STATEMENT RE: FEDERALLY SPONSORED RESEARCH/DEVELOPMENT
Not Applicable
BACKGROUND
The present invention relates to an infant seat for retaining an infant in an
infant seat at a seated position.
Infants do not have the necessary muscles or physical coordination to remain
at a seated position. As such, the infant requires support from all sides when
being
seated. Otherwise, the infant may fall rearward hitting his/her head on the
ground or
fall sideways hitting his/her head on the ground. Furthermore, in certain
circumstances, the infant may also fall forward thereby possibly hitting his
or her face
on the ground. Prior art infant seats have been developed to support the
infant at the
seated position which may be the preferable orientation during certain
activities such
as feeding.
One such prior art infant seat is disclosed in W000/65965 ('965 application)
which is an international application published under the Patent Cooperation
Treaty.
The `965 application discloses a prior art infant seat having a back rest, two
side
supports, a front post and a tray which is removably attachable to the two
side
supports and the front post. The prior art infant seat supports the infant at
the seated
position. Unfortunately, the prior art infant seat suffers from many
deficiencies. For
example, the tray is attached to the infant seat based upon a three point
attachment
system. In particular, lateral protuberances are formed on lateral sides of
the tray and
a front protuberance is formed on a forward portion of the tray. These
protuberances
are inserted into recesses formed on the two side supports and the front post
of the
prior art infant seat. The tray may be attached to the prior art infant seat
by inserting
CA 02662336 2009-03-02
WO 2008/030255 PCT/US2006/045747
2
the protuberances into the recesses and may be retained therein despite the
infant's
efforts to remove the tray. Unfortunately, the three point attachment system
is
unreliable because infants are strong enough to dislodge the protuberances
from the
recesses as the protuberances and recesses are fabricated from soft, flexible
foam. As
such, the child may unexpectedly remove the tray from the infant seat and fall
forward hitting his/her head or escape out of the prior art infant seat.
BRIEF SUMMARY
An infant seat discussed herein addresses the needs discussed above, below
and those known in the art. The infant seat may have a seat rest, back rest,
two side
supports and a front post. The two side supports, back rest and seat rest
define a
receiving cavity sized and configured to comfortably receive an infant
therein. The
front post and two side supports define two grooves which are sized and
configured to
receive the legs of the infant. An entrance or upper opening of the grooves is
sufficiently large to allow a parent to place the infant in the infant seat or
remove the
infant from the infant seat easily. Bottom surfaces of the grooves are
elevationally
higher than a rear portion of the seat rest. As such, when the infant is place
in the
infant seat, the infant is leaned backwards onto the back rest providing
support to the
child to support the child in the seated position. The rearward angle of the
seat rest
retains the child or infant in the infant seat due to the infant's inability
to lift himself
or herself out of the infant seat.
A pommel or tray may be selectively and removably attachable to the front
post. Various structures are disclosed herein for removably attaching the
pommel or
tray to the front post. Generally, a male member is fixedly attached to the
pommel or
tray. Also, a female member is fixedly attached to the front post of the
infant seat.
The male and female members have interlocking parts that allow the male and
female
parts to be engaged or disengaged. When the tray or pommel is attached to the
front
post, the infant is retained in the infant seat because the tray or pommel
blocks the
infant from lifting himself or herself out the infant seat. To remove the
infant from
the infant seat, the tray or pommel may first be disengaged from the front
post. The
discussion of the infant seat herein may describe the tray and pommel as
blocking or
preventing the infant from being removed from the infant seat or lifting
himself or
herself out of the infant seat when the tray or pommel is attached to the
front post of
CA 02662336 2009-03-02
WO 2008/030255 PCT/US2006/045747
3
the infant seat. However, such condition is not necessary. It is contemplated
that the
infant may be removed from the infant seat when the tray or pommel is still
attached
to the front post. In this case, it may just be easier to remove the infant
from the
infant seat with the pommel and tray attached to the front post.
In an aspect of the infant seat, a toy may be removably attachable to an upper
surface of the tray.

DETAILED DESCRIPTION
Referring now to the drawings which are for the purpose of illustrating the
preferred embodiments of the infant seat and not for the purpose of limiting
the same,
Figure 1 illustrates an infant seat 10 for supporting an infant 12 at the
seated position
and for retaining the infant 12 in the infant seat 10. Infants 12 do not have
developed
muscles and have not yet learned how to stabilize themselves in the seated
position
(see Figure 1). Rather, infants 12 when placed in the seated position tend to
fall over
to their sides or backwards onto their head. In certain circumstances, it is
desirable
for the infants 12 to be supported at the seated position. By way of example
and not
limitation, the seated position is the preferred orientation when the parent
is feeding
the infant 12. Moreover, due to the short attention span of the infant 12, it
is also
desirable to retain the infant 12 in the infant seat 10 in the seated position
to focus the
infant's attention at certain times such as during the feeding process. The
infant 12
may move around and may be distracted from other objects and events occurring
around the infant 12. Nonetheless, the parent must feed the infant 12 and
attempt to
maintain the attention of the infant 12 during the feeding process.
Beneficially, the
CA 02662336 2009-03-02
WO 2008/030255 PCT/US2006/045747
6
infant seat 10 may support the infant 12 in the seated position and retain the
infant 12
in the infant seat 10 at the seated position.
By way of example and not limitation, as shown in Figure 2, the infant seat 10
may comprise a seat rest 14, back rest 16, two side supports 18 and a front
post 20.
The seat rest 14 may provide an upper surface 22 upon which the infant 12 may
be
seated. The upper surface 22 of the seat rest 14 may be sized and configured
to
receive the buttocks of the infant 12. Preferably the upper surface 22 of the
seat rest
14 may have a curvilinear configuration so as to comfortably receive the
buttocks of
the infant 12. In this manner, the infant 12 will not be distracted while
seated in the
infant seat 10 due to the comfort level of the infant seat 10. The back rest
16 may be
attached to the seat rest 14 and extend vertically upward so as to support the
lower
back and/or, preferably, the upper back of the infant 12. The front surface 24
of the
back rest 16 may be curvilinearly joined to the seat rest 14 and extend
substantially
vertically upward so as to support the infant 12 to the seated position.
The two side supports 18 may be attached to the seat rest 14 and also the back
rest 16 on lateral sides tliereof. The side supports 18 may also be joined to
the seat
rest 14 in a curvilinear fashion and extend vertically upward. The two side
supports
18 may also be curvilinearly joined to the back rest 16. The front post 20 may
extend
vertically upward from a front portion 26 (see Figure 3) of the seat rest 14
and may be
joined in a curvilinear fashion to the seat rest 14. As shown in Figure 3, the
front
portion 26 of the seat rest 14, front post 20 and the two side supports 18
define two
grooves 28 which may be sized and configured to comfortably receive legs 30
(see
Figure 1) of the infant 12 when the infant 12 is seated in the infant seat 10.
The seat rest 14, back rest 16, two side supports 18 may define a cavity
having
a bulbous configuration which cooperates with each other so as to comfortably
receive the buttocks, legs 30 and back of the infant 12. As shown in Figure 2,
the
upper surfaces 32, 34 of the back rest 16 and two side supports 18 may have a
sloping
configuration with an apex 36 terminating at a medial portion of the back rest
16.
Upper surfaces 34 of the two side supports 18 are preferably sized, configured
and
positioned so as to support the infant's elbows and arms when the infant 12 is
seated
in the infant seat 10, as shown in Figure 1.
The front portion 26 (see Figure 3) of the seat rest 14 may be elevationally
higher than a rear portion 38 (see Figure 2) of the seat rest 14. Accordingly,
when the
CA 02662336 2009-03-02
WO 2008/030255 PCT/US2006/045747
7
infant 12 is seated in the infant seat 10, the infant 12 is leaned backwards
with his/her
thighs raised upwards above the infant's buttocks. Due to the undeveloped
muscles of
the infant 12 and the infant's inability to coordinate his/her movements, the
infant 12
will have a difficult time raising himself or herself out of the infant seat
10. As such,
the infant 12 is retained in the infant seat 10. Preferably, the seat rest 14
is angled
between about fifteen degrees and forty five degrees and is preferably angled
at about
a thirty three degree slope.
The seat rest 14, back rest 16, two side supports 18 and front post 20 may be
fabricated from a soft material such as polyurethane, rubber or other
compliant
material. The seat rest 14, back rest 16, two side supports 18 and front post
20 may
collectively define a base 40 (see Figure 1) of the infant seat 10. The base
40 of the
infant seat 10, as shown in Figures 7, 18, 19 and 20, may have a hollow cavity
42 with
an outer peripheral support member 44. The outer peripheral support member 44
may
have a plurality of webs 46 (see Figure 7) which interconnect the outer
peripheral
support member 44 and the seat rest 14. The webs 46 may extend to a lower
surface
48 (see Figures 1 and 18) of the outer peripheral support member 44 so as to
provide
additional support to the infant seat 10.
The infant seat 10 may have a tray 50 (see Figure 1) or pommel 52 (see Figure
8) which is removably attachable to the front post 20 (see Figure 2). The tray
50 or
pommel 52 at least partially extends over the infant's leg when the tray 50 or
pommel
52 is attached to the front post 20 and the infant 12 is seated in the infant
seat 10. In
this manner, the infant 12 is retained in the infant seat 10 because the tray
50 or
pommel 52 blocks the infant's access out of the infant seat 10.
As shown in Figures 1-6, a tray 50 may be removably attachable to the front
post 20. When the tray 50 is attached to the front post 20, the lateral
portions 54 (see
Figure 5) of the tray 50 may extend over the grooves 28 and the side supports
18. As
such, the tray 50 and the grooves 28 provide an aperture through which the
infant's
legs 30 are locked in place to retain the infant 12 in the infant seat 10 at
the seated
position. The tray 50 may have a flat upper surface 56 with a ridge 58 formed
around
the upper surface 56, a shown in Figure 1. The upper surface 56 may be
substantially
level with the ground so as to allow the parent to rest food and other items
on the
upper surface 56 when feeding the infant 12. If liquid is spilled on the upper
surface
CA 02662336 2009-03-02
WO 2008/030255 PCT/US2006/045747
8
56 of the tray 50, the ridge 58 holds the fluid and prevents the fluid from
spilling onto
the ground or off of the upper surface 56.
The tray 50 may be removably attached to the front post 20 via mating male
and female members 60, 62 (see Figures 4 and 5) of a first embodiment, as
shown in
Figures 2-6. The male member 60 may be secured to the underside 64 of the tray
50
witli screws 66, as shown in Figure 5. The male member 60 may have two
outwardly
biased flexible levers 68. Lateral sides of the levers 68 may have at least
one tooth 70
which is engageable with a toothed slot 71 of the female member 62. The levers
68
may be squeezed inwardly by depressing distal portions 72 (see Figure 5) of
the lever
68, as shown in Figure 6. By depressing the levers 68, the teeth 70 of the
levers 68
are also inwardly displaced. When the distal ends of the levers 68 are
released, the
teeth 70 and the levers 68 are outwardly displaced.
The male member 60 may have inwardly directed flanges 74 (see Figures 3
and 5) which are mateable with outwardly directed flanges 76 (see Figures 3
and 4) of
the female member 62. The outwardly directed flanges 76 of the female member
62
may be disposed above an upper surface 78 of the front post 20. The flanges 76
of the
female member 62 and the upper surface 78 (see Figure 4) of the front post 20
form
slots which may receive the flanges 74 of the male member 60 when attaching
the
tray 50 to the infant seat 10, and more particularly, the front post 20, as
shown in
Figure 3. When the flange 74 of the male member 60 is inserted into the slot,
the tray
50 may not be lifted upward due to the interference between the mating flanges
74,
76. The female member 62 may be molded into the front post 20, glued to the
front
post 20 or otherwise attached to the front post via any method discussed
herein or
known in the art. The female member 62 may be fabricated from a hard material
(e.g., plastic).
Also, the female member 62 may have first and second rows of toothed slot 71
which are inwardly oriented toward each other, as shown in Figure 4. The
toothed
slot 71 of the first and second rows may be sized and configured to engage the
teeth
70 of the male member levers 68. In particular, when the tray 50 is attached
to the
front post 20, the parent may squeeze the distal portions 72 of the levers 68
thereby
displacing the levers 68 and the respective teeth 70 inwardly. A width of the
male
member teeth 70 is now narrower compared to the teeth of the toothed slot 71
of the
female member 62. The teeth 70 of the male member 60 levers 68 clear the teeth
of
CA 02662336 2009-03-02
WO 2008/030255 PCT/US2006/045747
9
the toothed slot 71 of the female member 62 thereby allowing the flange 74 of
the
male member 60 to be inserted into the slot formed by the flange 76 of the
female
member 62 and the upper surface 78 of the front post 20. Once the tray 50 is
positioned, the distal portions 72 of the levers 68 may be released so as to
displace the
teeth 70 of the levers 68 outward and into engagement with the toothed slot 71
of the
female member 62. In this manner, the tray 50 is selectively positioned and
may not
be pushed forward, away from the infant 12 or pushed rearward, toward the
infant 12.
The forward/rearward position of the tray 50 may be adjusted by disengaging
the
teeth 70, 71 of the male and female members 60, 62 by depressing the distal
portions
72 of the levers 68 and subsequently engaging the teeth 70 of the levers 68 to
corresponding toothed slot 71 of the female member 62 by releasing the levers
68.
In use, the tray 50 may be removed from the front post 20 of the infant seat
10
to allow easy removal of the infant 12 from the infant seat 10. The reason is
that
when the tray 50 is attached to the front post 20, the parent may not simply
lift the
infant 12 upward to remove the infant 12 from the infant seat 10. Rather, the
parent
must slide the legs 30 of the infant 12 out of the aperture formed by the
grooves 28
and the tray 50 to remove the infant 12 from the infant seat 10. Since the
tray 50 is
removably attachable from the front post 20, the parent may remove the tray 50
from
the front post 20 to facilitate removal of the infant 12 from the infant seat
10. After
the tray 50 is removed, the infant 12 may be lifted upward for removal from
the infant
seat 10. In a similar manner, the tray 50 may be removed from the front post
20 for
facilitating seating of the infant 12 in the infant seat 10.
The infant 12 is retained in the infant seat 10 due to the rearward angle of
the
seat rest 14 thereby leaning the infant 12 back onto the back rest 16.
Moreover, the
infant 12 may be retained in the infant seat 10 by attaching the tray 50 to
the front
post 20. When the tray 50 is attached to the front post 20, the tray 50
extends over the
grooves 28. The grooves 28 and the tray 50 form apertures through which the
legs 30
of the infant 12 are disposed. When the legs 30 of the infant 12 are disposed
in the
apertures, the infant 12 may not simply lift himself or herself out of the
infant seat 10.
In another aspect, the tray 50 may be replaced with a pomme152, as shown in
Figure 8. Figure 8 illustrates a second embodiment of the infant seat 10. The
pommel
52 may have a bulbous configuration and a soft exterior surface to prevent the
infant
12 from hurting himself or herself when grabbing the pommel 52. The pommel 52
CA 02662336 2009-03-02
WO 2008/030255 PCT/US2006/045747
may extend laterally outward from the front post 20 and be disposed at least
partially
over the grooves 28 formed by the front post 20, seat rest 14 and the two side
supports
18. In this manner, the baby when seated in the infant seat 10 may find it
difficult to
lift himself or herself out of the infant seat 10 because the space between
the pommel
5 52 and the side supports 18 may be less than an outer diameter of the
infant's legs 30.
More particularly, the pommel 52 may extend laterally outward such that an
outer
periphery 80 of the pommel 52 and the two side supports 18 define a distance
which
is less than the outer diameter of the infant's leg. In this manner, the
pommel 52
creates an additional retaining force when the infant 12 attempts to raise
himself or
10 herself out of the infant seat 10. The infant's leg simultaneously contacts
the pommel
52 and the two side supports 18. Since the space between the pommel 52 and the
two
side supports 18 is less than the outer diameter of the infant's leg, the
infant 12 is
prevented from escaping out of the infant seat 10.
When the parent desires to remove the infant 12 from the infant seat 10, the
pommel 52 may be removed from the front post 20 thereby enlarging the space
between the front post 20 and the two side supports 18. The parent or
caretaker may
lift the infant 12 out of the infant seat 10 at this moment. The pommel 52
shown in
Figure 8 may be removably attachable to the front post 20 in a similar fashion
as
described in Figures 1-6 with mating male and female members 60, 62. The
female
member 62 may be molded into the front post 20 as described in relation to
Figures 1-
6. Also, the male member 60 may be molded into the pomme152.
Figure 9 is a cross-sectional view of a pommel 52 removably attachable to the
front post 20 illustrating a third embodiment. The pommel 52 is removably
attachable
to the front post 20 via a male member 82 attached to the pommel 52 and a
female
member 86 attached to the front post 20. The male meinber 82 may comprise a
left
lever 84a and a right lever 84b which are traversable between a relaxed
position and a
depressed position. Preferably, the left lever 84a may have a mirror
configuration
compared to the right lever 84b. The left and riglit levers 84a, 84b may be
outwardly
biased and inwardly displaceable by depressing finger receiving surfaces 88 of
the left
and right levers 84a, 84b. Distal ends of the left and right levers 84a, 84b
may have
pawls 90 attached thereto. The pawls 90 may have a beveled surface 92 which
cooperates with the female member 86 to inwardly displace the left and right
levers
CA 02662336 2009-03-02
WO 2008/030255 PCT/US2006/045747
11
84a, 84b when attaching the pommel 52 to the front post 20. The pawls 90 may
be
removably engageable to the female member 86.
The female member 86 may have an inverted hat configuration. A cavity 100
may be formed at a central portion of the female member 86 which is sized and
configured to receive the pawls 90 of the left and right levers 84a, 84b. More
particularly, a leading edge 102 of the aperture may be sized and configured
to mate
with the beveled surfaces 92 of the left and right lever 84a, 84b pawls 90
when the
pommel 52 is being attached to the female member 86. In the relaxed position,
the
pawls 90 are aligned to the leading edge 102 of the female member 86 aperture.
Due
to the angle of the beveled surface 92, the levers 84 are inwardly displaced
when the
beveled surfaces 92 contact the leading edge 102 of the aperture and the
pommel 52 is
engaged to the front post 20. As the pommel 52 is pushed into engagement with
the
front post 20, the pawls 90 are contained within the cylindrical portion of
the female
member 86. As the pawls 90 are further inserted into the aperture of the
female
member 86, the lower distal ends 98 of the finger receiving surfaces 88
contacts a rim
96 of the female member 86 preventing further insertion of the pawls 90 into
the
aperture. At about this moment, the pawls 90 are displaced outwardly and
received
into openings defining cam surfaces 104. The cam surfaces 104 engage the pawls
90
and the pomme152 is locked to the front post 20.
To remove the pommel 52 from the front post 20, the parent may inwardly
depress the finger receiving surfaces 88 which disengage the pawls 90 from the
cam
surfaces 104. At this point, the pommel 52 may be lifted out of the apei-ture
of the
female member 86 and the pomme152 is disengaged and removed from the front
post
20.
The parent may place the infant 12 into the infant seat 10 by first removing
the
pommel 52 from the front post 20 by depressing the finger receiving surfaces
88 and
pulling upward on the pommel 52. Thereafter, the infant 12 is placed in the
infant
seat 10 and leaned against the back rest 16 in the seated position. Once the
infant 12
is in the seated position, the parent may attach the pommel 52 to the front
post 20.
The distance between the outer periphery 80 of the pommel 52 and the two side
supports 18 may be less than an outer diameter of the infant's leg 30 thereby
preventing the infant 12 from pushing himself or herself up out of the infant
seat 10
due to the interference between the legs 30 of the infant 12 and the pomme152.

Figures 10 and 11 illustrate a fourth embodiment. In particular, a male
member, 110 may be fixedly attached to the pommel 112 and may be removably
engageable to a female member 114 fixedly attached to the front post 20 (see
Figure
2). The male member 110 may have a downwardly protruding post 116 (see Figures
10 and 11) with a hollow lower cavity 118 (see Figure 11). The downwardly
protruding post 116 may have a cylindrical configuration and may define a
circular
wall and a lower distal end 120 (see Figure 11). The hollow lower cavity 118
may
define an upper surface 122. A compression spring 124 may be fixedly attached
to
the upper surface 122 of the hollow lower cavity 118. The downwardly
protruding
post 116 may have at least one tab 126 which extends radially outward from
post 116.
Preferably, the post 116 may have two tabs 126 on opposing sides thereof.
The female member 114 may have an aperture. The aperture may be defined
by a cylindrical wall 127 (see Figure 11). The cylindrical wall 127 may have a
slot
128 (see Figure 10) having a J-configuration. The slot 128 may have an
entrance
portion 130 which extends from a leading edge 132 (see Figure 11) of the
aperture
and a locking portion 134 which hooks upward. The rim 136 of the female member
114 may have a cut out 138 aligned to the entrance portion 130 of the slot 128
for
allowing the tab 126 to enter the entrance portion 130 of the J-configured
slot 128.
The center of the aperture may have a raised portion 140 which may be sized
and
configured to receive the spring 124.
To attach the pommel 112 to the front post 20, the post 116 is inserted into
the
aperture of the female member 114. The tab 126 is received into the entrance
portion
130 of the slot 128 of the female member 114 via the cut-out 138 and the
spring 124
may press against the raised portion 140 of the female member 114. The post
116 is
inserted fully into the aperture of the female member 114 then rotated
counterclockwise to align the tab 126 to locking portion 134 of the slot 128.
The
spring 124 lifts the tab 126 into the locking portion 134 of the J-configured
slot 128
such that the child or infant 12 may not remove the pommel 1,12 from the front
post
20. To remove the pommel 112 from the front post 20, the parent may push down
on
the pommel 112 until the tab 126 is released from the locking portion 134 of
the J-
configured slot 128. The pommel 112 is rotated in the clockwise direction and
the tab
126 is aligned to the entrance portion 130 of the slot 128. The tab 126
traverses
through and out of the entrance portion 130 via the cut out 138 and the post
116 is
CA 02662336 2009-03-02
WO 2008/030255 PCT/US2006/045747
13
lifted out of the aperture of the female member 114. In this manner, the
pommel 112
is removed from the front post 20.
The pommel 112 shown in Figures 10 and 11 may extend outward over the
grooves 28 when the pommel 112 is attached to the front post 20 to block the
infant
12 from standing up out of the infant seat 10. The pommel 112 blocks the
infant 12
from standing up because a distance between the outer periphery of the pommel
112
and the two side supports 18 may be less than an outer diameter of the legs 30
of the
infant 12.
The fourth embodiment of the infant seat 10 was described in a manner that
counter clockwise rotation of the pommel 112 engaged the pommel 112 to the
front
post 20 and cloclcwise rotation of the pommel 112 disengaged the pommel 112
from
the front post 20. However, it is also contemplated that the structure of the
male and
female members 110, 114 may be reversed such that the pommel 112 is engageable
to
the front post 20 via a clockwise rotation of the pommel 112 and the pommel
112 is
disengageable from the front post 20 via a counter clockwise rotation of the
pommel
112.
Figures 12-16 illustrate a fifth embodiment of removably attaching a pommel
154 to the front post 20. As shown, the pommel 154 may be removably attachable
to
the front post 20 via mating male and female members 150, 152. The male member
150 may be embedded into the pommel 154. Likewise, the female member 152 may
be embedded into the front post 20. The male member 150 may comprise a
plurality
of flanges 156 vertically and perpendicularly aligned to each other. For
example, as
shown in Figure 12, four flanges 156 are perpendicularly aligned to each other
forming a cross configuration. Other angular orientations of the flanges 156
are also
contemplated such as eight flanges 156 at forty five degrees with respect to
each
other. Additionally, it is also contemplated that there may be more than four
flanges
156 or less than four flanges 156. A proximal portion of the flanges 156 may
be
attached to the pommel 154 by molding the pommel 154 over the proximal portion
of
the flanges 156. Distal portions of the flanges 156 may have a notch 158 and a
stop
160. In particular, at least one of the flanges 156 may have a notch 158
formed at a
distal portion thereof. Also, at least one of the flanges 156 may have a stop
160
formed at a distal portion thereof. Preferably, opposing flanges 156 have
notches 158
formed at distal portions thereof, and the second set of opposing flanges 156
have
CA 02662336 2009-03-02
WO 2008/030255 PCT/US2006/045747
14
stops 160 formed at distal portions thereof. The notches 158 are removably
engageable to a lower plate 162 of the female member 152.
The female member 152 may have a central aperture 164 (see Figure 13) in
which the flanges 156 may be inserted. The lower plate 162 may be attached to
the
distal portion of the central aperture 164. The lower plate 162 may have a
notch 168
for receiving the flange 156 of the male member 150. To attach the pommel 154
to
the front post 20, the distal ends of the flanges 156 extend past the lower
plate 162
through the notch 168 of the lower plate 162 until the stop 160 contacts the
lower
plate 162 (see Figure 14). The notches 158 of the flanges 156 are aligned to
the lower
plate 162. Once the flange notches 158 are aligned to the lower plate 162, the
pommel 154 is rotated (see Figures 14 and 15) to lock the pommel 154 to the
front
post 20, as shown in Figures 14-15. The lower plate 162 is received into the
notches
158 of the male member 150 (see Figure 16). In this manner, the pommel 154 may
not be removed from the front post 20. The lower plate 162 may have an
enlarging
thickness defining a cam surface wherein the thinnest portion of the lower
plate 162 is
adjacent the notch 158 of the lower plate 162. As the pommel 154 is rotated
(see
Figure 15), the cam surface frictionally engages the notch 158 of the male
member
150 (see Figure 16). Preferably, the notch 158 frictionally engages the cam
surface
when the pommel 154 is rotated about 40 degrees, as shown by reference numeral
166
in Figure 16.
To remove the pommel 154 from the front post 20, the pommel 154 is rotated
in the opposite direction. The flange 156 of the male member 150 is then
aligned to
the notch 168 of the lower plate 162. Also, the notch 158 of the flange 156
releases
the cam surface or the lower plate 162. The male member 150 may now be removed
from the female member 152 and the pommel 154 released from the front post 20.
Figures 17 and 18 illustrate a sixth embodiment of removably attaching a tray
50 to the infant seat 10. In particular, the tray 50 may have a mushroom head
type
protuberance 170 with a bulbous distal portion 172 attached to an underside of
the
tray 50. As used herein, bulbous may mean round balloon configuration, star
shape,
box shape or any other enlarged shaped. The protuberance 170 is receivable
into a
corresponding cavity 173 formed in the front post 20. The mushroom head type
protuberance 170 may be compressed such that the mushroom head type
protuberance
170 may slide into the cavity 173 of the front post 20 and be engaged thereto.
A
CA 02662336 2009-03-02
WO 2008/030255 PCT/US2006/045747
distal or lower surface of the cavity 173 may have a through hole 174 to allow
air to
be ejected out of the cavity 42 or introduced into the cavity 173 when the
mushroom
head type protuberance 170 is inserted into or removed from the cavity 173. In
this
manner, the cavity 173 does not create any pressure or vacuum when the
mushroom
5 head type protuberance 170 is inserted into or removed from the cavity 173.
The
protuberance 170 may optionally have a vertical slit 176 which extends from a
distal
end of the protuberance 170 and extend upward to assist in inserting and
removing the
protuberance 170 from the cavity 173.
More particularly, the protuberance 170 may be attached to an underside of
10 the tray 50 or pommel. The protuberance 170 may be sized and configured to
be
mateable with a cavity 173 formed in the front post 20 of the infant seat 10.
By way
of example and not limitation, the protuberance 170 may have an elongate
structure.
A distal portion 172 of the protuberance 170 may have a bulbous configuration.
Similarly, the cavity 173 formed in the front post 20 may have an elongate
15 configuration. A distal portion 178 of the cavity 173 may have a mating
bulbous
configuration. For example, if the bulbous distal portion 172 has a box
configuration,
then the distal portion 178 of the cavity 173 may also have a box
configuration. To
attach the tray 50 to the front post 20, the distal portion 172 of the
protuberance 170 is
aligned to an entrance of the cavity 173. The tray 50 is pushed downward until
inner
side walls of the cavity 173 apply radial inward forces to the bulbous distal
portion
172 of the protuberance 170. Such radial inward forces reduce the diameter of
the
bulbous portion 172 such that the bulbous portion 172 may slide past a neck
180 of
the cavity 42. Once the bulbous portion 172 traverses downward past the neck
180 of
the cavity 42, the bulbous portion 172 expands to fill the bulbous configured
portion
184 of the cavity 173.
To remove the tray 50 from the front post 20, the protuberance 170 is removed
from the cavity 173. In particular, the parent may lift the tray 50 upward
which urges
the bulbous distal portion 172 of the protuberance 170 upward. The neck 180 of
the
cavity 173 applies radial inward forces which reduces the diameter of the
bulbous
portion 172 such that the bulbous portion 172 may slide past the neck 180 of
the
cavity 42. Once the bulbous portion 172 traverses upward past the neck 180 of
the
cavity 173, the protuberance 170 may easily be removed from the cavity 173 and
the
tray 50 is disengaged from the front post 20.

Under normal usage, the infant 12 should not be able to create sufficient
upward force to remove the protuberance 170 from the cavity 42 formed in the
front
post 20. Also, the parent should be able to easily lift the tray 50 so as to
disengage the
tray 50 from the infant seat 10.
The amount of force required to insert the protuberance 170 into the cavity
173 and remove the protuberance 170 from the cavity 173 may be increased or
decreased by altering the surface texture, surface treatment and type of
material for
the protuberance 170 and the front post 20.
Figure 19 illustrates a seventh embodiment wherein a tray 50 is removably
attachable to an infant seat 10. In particular, a tapered shaft 190 is
frictionally
engageable to a corresponding tapered cavity 192 formed in the front post 20
to attach
the tray 50 to the infant seat 10. The shaft 190 may have a reducing diameter
starting
from a proximal portion of the shaft 190 and ending at a distal portion of the
shaft
190. The cavity 192 formed in the front post 20 may have an identical
configuration
compared to the shaft 190.
To engage the tray 50 to the infant seat 10, the shaft 190 is inserted into
the
cavity 192. The outer surface of the shaft 190 begins to engage the inner
surface of
the cavity 192. The shaft 190 is fully inserted when a stop 194 contacts the
upper
surface 78 of the front post 20. When the shaft 190 is fully inserted into the
cavity
192, the shaft 190 is frictionally engaged to the cavity 192. An infant 12
seated in the
infant seat 10 is not able to lift the tray 50 up because of the frictional
engagement
between the shaft 190 and the cavity 192. Moreover, the infant 12 is not able
to push
the tray 50 forward or pull the tray 50 backward because the shaft 190 is
fixedly
engaged to the tray 50 and frictionally engaged to the cavity 192.
The tray 50 may be removed from the infant seat 10 to assist in the removal or
seating of the infant 12 in the infant seat 10. In particular, the parent may
lift up the
tray 50 overcoming the frictional engagement between the shaft 190 and the
cavity
192. After the frictional engagement between the shaft 190 and cavity 192 has
been
overcome, the parent may remove the tray 50 from the infant seat 10. Although
Figure 19 illustrates a tray 50 which is removably attachable to the infant
seat 10, it is
also contemplated that a pommel may be removably attachable to the infant seat
10
via the structure shown in Figure 19.

Figure 20 illustrates an eighth embodiment wherein a tray 50 is removably
attachable via a push button locking mechanism 200. In particular, the tray 50
may be
attached to an elongate shaft 202. The elongate shaft 202 may have a cam
surface
204 positionable adjacent to a push button 206. The push button 206 may
comprise a
button, spring 208 and a latch 210. The latch 210 is traversable from a
retracted
position (see Figure 20) to a release position by depressing the button. When
the
button is released, the latch 210 is traversed from the release position to
the retracted
position. The latch 210 may be biased toward the retracted position.
The latch 210 may have a hook configuration. The latch 210 may engage the
cam surface 204 of the elongate shaft 202 when the elongate shaft 202 is
inserted into
a cavity of the front post 20 and the latch 210 is traversed to the retracted
position.
When the latch 210 engages the cam surface 204, the tray 50 is engaged to the
front
post 20 and may not be removed by the infant 12. To remove the tray 50 from
the
infant seat 10, the parent may depress the button which is preferably
positioned out of
the reach of the infant 12 when the infant 12 is seated in the infant seat 10.
For
example, the button may be positioned at a lower central portion of the front
post 20.
When the button is depressed, the latch 210 is traversed to the released
position. The
parent may lift the tray 50 upward and remove the shaft 202 out of the cavity
and the
tray 50 from the infant seat 10. Although Figure 20 illustrates a tray 50
which is
removably attachable to the infant seat 10, it is also contemplated that a
pommel may
be removably attachable via the method shown in Figure 20. Preferably, it is
contemplated that the button may be located at any position on the infant seat
10 so
long as the infant 12 is not able to reach the button when seated in the
infant seat 10.
Figures 21-29 illustrate a ninth embodiment of releasably attaching the
pommel 220 to the front post 20. To engage the pommel 220 to the front post
20, the
pommel 220 may be molded with a male member 222 (see Figure 21 a) such that
the
male member 222 is fixedly attached to the pommel 220 (see Figures 21a and
23).
Also, the front post 20 may be fixedly attached to a female member 224 (see
Figures
21 a and 23). The female and male members 224, 222 may be fixedly attached to
the
front post 20 and pommel 220 via any method known in the art such as molding,
adhesive connections, etc. To engage the pommel 220 to the front post 20, the
male
member 222 may be inserted into the female member 224 (see Figures 21a and 23)
and pushed downwardly. To disengage the pommel 220 from the front post 20, the
CA 02662336 2009-03-02
WO 2008/030255 PCT/US2006/045747
18
male and female members 222, 224 may be fabricated so as to require one or two
motions. By way of example and not limitation, the pommel 220 may be removed
from the front post 20 by rotating the pommel 220 counterclockwise (see Figure
22b).
Alternatively, the male and female members 222, 224 may be fabricated so as to
require that the parent push down (see Figure 22a) and rotate (see Figure 22b)
the
pommel 220 countercloclcwise to disengage the pommel 220 from the front post
20.
The male member 222 may have an upper portion 226 and a lower portion
228, as shown in Figure 23. The upper portion 226 of the male member 222 may
be
fixedly attached to the pommel 220. By way of example and not limitation, the
pommel 220 may be molded over the upper portion 226. The upper portion 226 may
have a plurality of apertures 230 such that the pommel material is interlocked
into the
upper portion 226 when the pommel 220 is molded over the upper portion 226.
The
bottom surface 232 of the pommel 220 may have a skirt 234 which may be sized
and
configured to receive the front post 20, as shown in Figures 21-21b. The lower
portion 228 of the male member 222 may have a cylindrical configuration (see
Figure
23). The lower portion 228 may comprise opposed inwardly displaceable tangs
236.
These tangs 236 may be sized and configured to be insertable into the female
member
224 and be engageably removable from the female member 224. More particularly,
each tang 236 may have a base portion 238 which is attached to the upper
portion
226. The tang 236 may also define a distal hook 240 having at least one nub
242
directed outwardly. Above the hook 240, a neck portion 244 may define a
receiving
area 246 for receiving a beveled protrusion 248 (Figure 24) of the female
member 224
to interlock the male and female members 222, 224.
Referring to Figures 23 and 24, the female member 224 may have a central
aperture 250 through which the lower portion 228 of the male member 222 may be
inserted. The central aperture 250 of the female member 224 may have a
cylindrical
configuration. The beveled protrusion 248 with an angled upper surface 252 may
be
formed along the inner surface of the central aperture 250. The beveled
protrusion
248 may be alignable to the tangs 236 when the pommel 220 is being engaged to
the
front post 20. As discussed above, the pommel bottom surface 232 may have a
skirt
234 which is formed to have a close fit with the front post 20. If the pommel
skirt 234
is angularly misaligned to the front post 20, the tangs 236 are not aligned to
the
beveled protrusion 248. Moreover, the pommel 220 would not be engageable with
CA 02662336 2009-03-02
WO 2008/030255 PCT/US2006/045747
19
the front post 20 based on a view that the skirt 234 of the pommel 220 would
interfere
with the front post 20. When the skirt 234 of the pomme1220 is aligned to the
front
post 20 would the tangs 236 be aligned to the beveled protrusions 248.
To engage the pommel 220 to the front post 20, the lower portion 228 of the
male member 222 is inserted into the aperture 250 of the female member 226.
(See
Figure 23). The skirt 234 of the pommel 220 is aligned to the front post 20
thereby
aligning the tangs 236 to the beveled protrusions 248. The pommel 220 is then
pushed downwardly such that the hooks 240 or distal ends of the tangs 236 (see
Figure 23) would contact the beveled surface 252 (see Figure 24) of the
beveled
protrusion 248. As the pommel 220 is further pushed downwardly, the beveled
surface 252 inwardly displaces the tangs 236 thereby moving the hooks 240 or
nubs
242 out of the way of the beveled protrusions 248. Before the hooks 240 engage
the
beveled protrusion 248, the bottom surface 232 of the pommel 220 may contact
the
upper surface 78 of the front post 20. To engage the hook 240 to the beveled
protrusion 248, it is preferable that the parent or user provide an increased
downward
push or downward force to engage the hook 240 to the beveled protrusion 248.
When
the pommel 220 is engaged to the front post 20, the beveled protrusion 248 may
be
positioned within the neck portion 244 of the tang 236. Preferably, an upper
surface
254 (see Figure 23) of the hook 240 and a bottom surface 256 (see Figure 24)
of the
beveled protrusion 248 have interlocking mating surfaces or interlocking
configurations. For example, the upper surface 254 of the hook 240 may be
parallel
with a transverse plane to a central axis 258 (see Figure 23) of the male
member 222.
Also, the bottom surface 256 of the beveled protrusion 248 may be parallel
with a
transverse plane to a central axis 260 (see Figure 23) of the female member
224. In
this manner, even though the pommel 220 may be pulled upwardly, the beveled
protrusions 248 do not inwardly displace the tangs 236 so as to release the
pommel
220 from the front post 20. More preferably, the upper surface 254 of the hook
240
and the bottom surface 256 of the beveled protrusion 248 may have interlocking
upward configurations as shown in Figure 25. As such, when the hook 240 is
mated
to the beveled protrusion 248, the respective surfaces 254, 256 would
interlock. Any
upward force applied to the pommel 220 would force the hook 240 further into
the
beveled protrusion 248 thereby ensuring engagement between the pommel 220 and
CA 02662336 2009-03-02
WO 2008/030255 PCT/US2006/045747
the front post 20. When the pommel 220 is engaged to the front post 20, the
beveled
protrusion 248 may be positioned within the neclc portion 244 of the tang 236.
The pommel 220 may be removed from the front post 20 by rotating the
pommel 220 (e.g., 45 degree) with respect to the front post 20, as shown in
Figure
5 22b. As discussed above, the skirt 234 of the pommel 220 is generally
configured to
the front post 20. As such, any rotation of the pommel 220 would be resisted
by the
skirt 234 of the pommel 220. However, the pommel 220 may be manufactured or
fabricated from a generally flexible and resilient material. As such, under
sufficient
rotational force, the skirt 234 would flex and the pommel 220 may be rotated
with
10 respect to the front post 20. When the pomme1220 is rotated with respect to
the front
post 20, the beveled protrusion 248 (see Figure 24) slides or rotates away
from the
tang 236 (i.e., neck portion 244) (see Figure 23) and into a slotted portion
262 (see
Figure 23) of the lower portion 228 of the male member 222. The pommel 220 may
be lifted up so as to slide the beveled protrusion 248 through the slotted
portion 262 of
15 the lower portion 228 of the male member 222. The pommel 220 is now
disengaged
from the front post 20. Such disengagement occurred by the motion of twisting
the
pommel 220.
Alternatively, the pommel 220 may be removable from the front post 20 via
two motions, namely, a downward force (see Figure 22a) and twisting action
(see
20 Figure 22b). For example, the tang 236 may also have a lip 264 (see Figure
23a)
which joins the hook 240 and the neck portion 244, as shown in Figure 23a. The
lip
264 would interfere with the beveled protrusion 248 if the pommel 220 was only
rotated thus preventing the beveled protrusion 248 from being aligned to the
slotted
portion 262 of the lower portion 228 of the male member 222. To align the
beveled
protrusion 248 to the slotted portion 262, the user must push downwardly on
the
pommel 220 such that the beveled protrusion 248 clears the lip 264 of the tang
236, as
shown by arrow 266 in Figure 23a. Now the user or parent may rotate the pommel
220 to align the beveled protrusion 248 to the slotted portion 262. The pommel
220
may be raised, the beveled protrusion 248 slid through the slotted portion 262
and the
pomme1220 is now disengaged from the front post 20.
As discussed above, the female member 224 may be fixedly engaged to the
front post 20 via adhesive, molding or any other method known in the art. One
method not known in the art will be described below. By way of example and not

21
limitation, the female member 224 may be selectively engageable to a locking
ring
268 (see Figure 26). The locking ring 268 may be molded into the front post 20
and
an aperture 270 may be formed through the front post 20 extending between the
upper
surface 78 of the front post 20 to the locking ring 268, as shown in Figure
27. The
female member 224 may have a plurality of flanges 272, as shown in Figure 28.
These flanges 272 may be inserted into the aperture 270 of the front post 20.
Distal
ends 274 of the flanges 272 may have notches 276 formed therein, as shown in
Figure
28. The notches 276 may be horizontally aligned to each other.
The locking ring 268 may have a corresponding number of apertures 278 as
there are flanges 272 as shown in Figure 26. The apertures 278 of the loclcing
ring
268 may be sized and configured to receive the distal ends 274 of the flanges
272. In
particular, each aperture 278 may have a first longer slot 280 which is sized
and
configured to receive a distal end 274 of the flange 272. As such, the flanges
272
may be aligned and inserted into the first longer slots 280. The flange 272
may also
have a stop surface 282 (see Figure 28) which contacts an upper surface 284
(see
Figure 27) of the locking ring 268. When the stop surface 282 contacts the
upper
surface 284 of the locking ring 268, the flange 272 is fully inserted into the
first
longer slot 280. A lower surface 286 of the locking ring 268 may have locking
tabs
288 and biasing tabs 290, as shown in Figure 26. Preferably, as shown in
Figure 26,
opposed apertures 278 may have the locking tabs 288 attached to a periphery of
the
first longer slot 280. Also, the second set of opposed apertures 278 may have
the
biasing tabs 290 which urge the flanges 272 from the first slot 280 to the
second slot
292.
After the flanges 272 are fully inserted into the first slot 280 of the
aperture
278, the biasing tabs 290 and locking tabs 288 are flexed upwardly. The female
member 224 may be subsequently rotated so as to align the flange 272 to a
second
smaller slot 292 (see Figure 26) via the biasing tabs 290 or by physically
rotating the
female member 224. At this position, the locking ring 268 is received into
notches
276. Also, the female member 224 may not be lifted out of the locking ring
268.
Moreover, the locking tabs 288 flex forward (see Figure 29) so as to prevent
the
flange 272 from being re-alignable to the first longer slot 280. More
particularly, the
biasing tab 290 may be attached to the locking ring 268 at a periphery of the
first slot
280. When the female member 224 is fully engaged to the locking ring 268 and
the
CA 02662336 2009-03-02
WO 2008/030255 PCT/US2006/045747
22
flanges 272 are aligned to the second slot 292, the female member 224 may be
squared to the front post 20 and the infant seat 10.
Referring now to Figures 30-33, a tenth embodiment of removably attaching a
tray 294 to a front post 296 of an infant seat 298 is illustrated. The.tray
294, and more
particularly, the underside surface 300 (see Figure 32) of the tray 294 may be
attached
a male member 302 via any method lcnown in the art (e.g., adhesive, screws,
etc.). A
mating female member 304 (see Figure 31) may be fixedly attached to the front
post
296 of the infant seat 298 via any method known in the art or described
herein. The
male and female members 302, 304 may have inter locking slots 306 a, b and
flanges
308 a, b (see Figures 31 and 32) such that the tray 294 may not be lifted
upward once
the tray 294 is engaged to the front post 296. Additionally, the male and
female
members 302 and 304 may have mating ridges 310 a, b (see Figures 31, 32, and
32A)
to prevent or resist forward/backward movement of the tray 294 with respect to
the
front post 296. To engage the tray 294 to the front post 296, the flange of
308b male
member 302 is aligned to the slot 306a formed by the female member 304 and the
front post 296. The flange 308b of the male member 302 is received into the
slot
306a of the female member 304 and the tray 294 is pushed rearward toward the
infant.
The ridges 310b of the male member 302 may flex upward and engage the ridges
310a of the female member 304. The tray 294 may be positionable in a forward
rearward direction by engaging the ridges 310 of the male member 302 deeper
into
the ridges 310a of the female member 304. The ridges 310a of the female member
304 push the male member 302 upward, as shown by force 312 in Figure 32A, such
that the ridges 310b of the male member 302 clear the ridges of the female
member
304when the tray 294 is pushed rearwardly.
Conversely, to remove the tray 294 from the front post 296, the tray 294 is
urged forward. As the tray 294 is pushed forwardly, the ridges 310b of the
male
member 302 slide over the ridges 310a of the female member 304 until the
ridges
310b of the male member 302 entirely or completely disengage the ridges 310a
of the
female member 304. The flange 308b of the male member 302 is removed from the
slot 306a of the female member 304, and thus, the tray 294 is removed from the
front
post 296.
More particularly, as shown in Figure 30 and 31, the female member 304 and
the front post 296 may form slots 306a which are opened outwardly. The female
CA 02662336 2009-03-02
WO 2008/030255 PCT/US2006/045747
23
member 304 may also include a plurality of ridges 310a interposed between the
slots
306a. The ridges 310a of the female member 304 may comprise at least one, and
preferably three resisting ridges 314 and one enlarged stopping ridge 316. The
resisting ridges 314 are positioned in front of the stopping ridge 316. When
the tray
294 is engaged to the front post 296, the ridges 310b of the male member 302
may
slide over the resisting ridges 314. However, when the ridges 310b of the male
member 302 contact the stopping ridge 316, the tray 294 stops moving
rearwardly
because the ridges 310b of the male member 302 may not slide over the stopping
ridge 316. Accordingly, the tray 294 may not be positioned beyond the stopping
ridge
316.
The male member 302 may be attached to the underside surface 300 of the
tray 294 via any method known in the art. The male member 302 may comprise a
base portion 318 which is attached to the tray 294 and a lever 320 pivotable
with
respect to the base portion 318. The lever 320 may be engaged to the base
portion
318 with interlocking hooks 322. When the lever 320 is engaged to the base
portion
318, the ridges 310b or the lever portion 320 is flexed upwardly, as shown by
the
dashed lines in Figure 32A. As such, when the ridges 310b of the male member
302
initially contact the ridges 310a of the female member 304, the ridges 310a of
the
female member 304 push the ridges 310b of the male member 302 upwardly. As
such, the ridges 310b of the male member 302 may slide over the resisting
ridges 314
of the female member 304 until the ridges 310b of the male member 302 contacts
the
stopping ridge 316.
The lever 320 is flexed upwardly in a bow configuration. The junction 324
(see Figure 32A) of the base portion 318 and the lever 320 may be sized and
configured so as to have gap 326 between the ridges of the male member 310b
and the
base portion 318. Additionally, on the proximal portion of the lever 320, a
support
member 328 may be formed. The support member 328 may contact the base portion
318 when the lever 320 is engaged to the base portion 318. As can be seen in
Figure
32A, the support member 328 and the junction 324 between the base portion 318
and
the lever 320 separate the ridges of the male member 310b from the base
portion 318.
The male member 302, and more particularly, the lever 320 may be fabricated
from a
bendable material. As such, when the ridges of the female member 3 10a push
the
CA 02662336 2009-03-02
WO 2008/030255 PCT/US2006/045747
24
ridges of the male member 310b upward, the lever 320 is bowed such that the
ridges
of the male member 310b may clear the ridges of the female resisting ridges
314.
In an aspect of the infant seat 10, the same may be formed with at least one
suction cup 420 (see Figure 18) for securing the infant seat 10 onto a support
member
(e.g., table top). In particular, a bottom surface of the seat rest 14 may
extend to the
lower distal end 48 of the outer peripheral member 44 of the base 40. The
bottom
surface may be formed with a suction cup 420, as shown in Figure 18. In use,
the
parent may place the infant seat 10 on a smooth table top. The parent pushes
down in
the direction of arrow "A" (see Figure 18) on the seat rest 14 which pushes
the suction
cup 420 against the smooth table top. The suction cup 420 creates a suction
force
with the table top. In this manner, the infant seat 10 is securable to a
support member
such as a table top.
In an. aspect of the infant seat 10, a toy 422 may be removably attachable to
the tray 50, as shown in Figures 34-37. As shown in Figure 34, an upper
surface 56
of the tray 50 may be formed with at least one depression 424. Preferably, the
upper
surface 56 of the tray 50 is formed with two depressions 424. These
depressions 424
may have a semi-circular bottom surface and opposing vertical side wall
surfaces 434
(see Figures 34 and 35). Nubs 426 are formed in the vertical opposing side
wall
surfaces 434 and oriented toward each other. The depressions 424 may be formed
at a
central location of the tray 50, or at any other convenient location.
An elongate member 428 may be removably engageable to the tray 50 via the
depressions 424. In particular, the elongate member 428 may have a rod like
configuration. The elongate member 428 may be bendable and flexible and may
also
hold its shape once it is bent or shaped. For example, the elongate member 428
shown in Figure 34 may initially be provided to the parent in a straight
configuration.
The parent may bend the elongate member 428 in the W-configuration shown in
Figure 34. Once the parent releases the elongate member 428, the elongate
member
428 may retain its shape. The elongate member 428 may have alternating large
and
small diameters throughout the entire length of the elongate member 428.
Distal
portions of the elongate member 428 may have a post 430 and a retaining ring
432 set
back from the distal end of the post 430.
In use, the elongate member 428 may be engaged to the tray 50 via the
depressions 424. In particular, an outer diameter 436 of the elongate member
428
CA 02662336 2009-03-02
WO 2008/030255 PCT/US2006/045747
may be slightly greater than a distance between tips of the nubs 426 formed on
opposing vertical side wall surfaces 434 of the depressions 424. To engage the
elongate member 428 to the depressions 424, the elongate member 428 is bent,
as
shown in Figure 34. A first portion of the elongate member 428 is pushed into
the
5 first depression 424. The outer diameter of the elongate member 428 pushes
the nubs
426 away from each other making room for the elongate member 428 to be
inserted
into the depression 424 below the nubs 426. Once the elongate meinber 428
traverses
past the nubs 426, the nubs 426 close in above the elongate member 428 thereby
holding the elongate member 428 within the depression 424. Lilcewise, a second
10 portion of the elongate member 428 is pushed into the second depression 424
to
engage the elongate member 428 to the tray 50 in a similar manner that the
first
portion was pushed into the first depression 424.
The toy 422 may have apertures 438 which are sized and configured to receive
the post 430 of the elongate member 428. After the elongate member 428 is
attached
15 to the tray 50, the posts 430 are inserted into the apertures 438 of the
toy 422 and
further insertion of the post 430 into the apertures 438 of the toy 422 is
prevented by
the retaining ring 432.
Figure 35 illustrates first and second depressions 424 being formed in the
tray
50 via inserts 440. The inserts 440 may have an inner surface having the
20 configuration of the depression 424. The inserts 440 are inserted into a
receptacle 442
formed in the tray 50. The insert 440 may be secured or fixedly attached to
the tray
50 via any method known in the art such as sonic welding, adhering and the
like.
Alternatively, Figures 35 and 36 illustrate a second method of engaging a toy
422 to the tray 50. In particular, the tray 50 may be formed with first and
second
25 receiving cavities 444. These cavities 444 are formed by inserts 446 having
an
inverted hat configuration. The cavities 444 are sized and configured to
receive (i.e.,
frictionally engage) the post 430 of the elongate member 428. As such, the
elongate
member 428 may be bent or configured or shaped into the configuration as shown
in
Figure 36. The posts 430 of the elongate member 428 are inserted into the
receiving
cavities 444 of the inserts 440 shown in Figure 34. Small toys 422 may be slid
through the elongate member 428 prior to engaging the elongate member 428 to
the
tray 50.
CA 02662336 2009-03-02
WO 2008/030255 PCT/US2006/045747
26
The toy 422 may also be removably attachable to the upper surface 56 of the
tray 50 via a suction cup 448, as shown in Figure 37. In particular, as shown
in
Figure 37, a suction cup 448 may be formed with one depression 424. The
depression
424 may be sized and configured to receive and secure the elongate member 428
to
the suction cup 448. The elongate member 428 may be shaped as shown in Figure
37.
A toy 422 with apertures 438 may subsequently be attached to the elongate
member
428 by inserting the posts 430 of the elongate member 428 in the apertures 438
of the
toy 422. The suction cup 448 may be removably engageable to the upper surface
56
of the tray 50 during use of the infant seat 10.
In an aspect of the infant seat 10, it is contemplated that the tray 50 or
pommel
52 may be removably engageable to the front post 20 via any of the embodiments
discussed herein. By way of example and not limitation, although the third
embodiment illustrates a pommel 52 being removably engageable to the front
post 20,
it is also contemplated the tray 50 may be removably engageable to the front
post 20
via the same method disclosed in the third embodiment.
In another aspect, it is also contemplated that the infant seat may be
removably
engageable to both the tray and/or pommel. For example, as shown in Figures 12-
16
illustrating the fifth embodiment, a male member 150 fixedly attached to the
pommel
154 may be inserted into the female member 152 and engaged thereto by twisting
the
pommel 154, the pommel 154 may be engaged or removed from the front post 20.
Also, as shown in Figures 13 and 15, the female member 152, and more
particularly,
the upper surface of the female member 152 is formed with the first and second
rows
of toothed slots 71 as described in Figures 2-6 illustrating the first
embodiment. In
this regard, the tray 50 illustrated in the first embodiment may be removably
attachable to the front post 20 via the male member 60 illustrated in relation
to the
first embodiment, as shown in Figure 5. Accordingly, it is contemplated that
the
infant seat 10 may be provided to a parent or user as a kit. The kit may
comprise the
infant seat 10 itself, the tray 50 which is removably attachable with the male
and
female members 60, 62 shown in the first embodiment and/or a pommel 154 which
is
removably engageable to the front post 20 via the male and female member 150,
152
as shown in the fifth embodiment. It is contemplated that the pommel 154 and
tray 50
may be removably engageable to the front post 20 via any of the methods
disclosed
herein. As such, the same male and female members 150, 152 may be respectively
CA 02662336 2009-03-02
WO 2008/030255 PCT/US2006/045747
27
engaged to the pommel/tray 154, 50 and front post 20 so as to make the
pommel/tray
154, 50 removably engageable to the front post 20.
In the various embodiments of the infant seat discussed above, reference may
have been made that the tray or ponnmel when attached to the front post
prevents the
infant from being removed from the infant seat or prevents the infant from
lifting
himself or herself out of the infant seat. However, such condition is not
required.
Rather, when the tray or pommel is attached to the front post, it may be more
difficult
to remove the infant from the infant seat or the infant may have more
difficulty in
lifting himself or herself out of the infant seat.
Additionally, the above discussion of the infant seat referenced parts
rotating
in the counter clockwise or clockwise direction. However, the rotating
direction of
the parts was made for convenience and is not a requirement. The rotation of
the
parts may be reversed. By way of example and not limitation, Figure 22b
illustrates a
user rotating the pommel in a counter clockwise direction to remove the pommel
from
the front post of the infant seat. It is contemplated that the front post and
the pommel
structure may be reversed such that pommel is removed from the front post by
rotating the pommel in the clockwise direction.
Moreover, the above discussion of the infant seat discussed certain parts as
being molded to the infant seat. However, such condition is also not required.
Rather, the parts may be attached to the infant seat in any manner discussed
herein or
known in the art. By way of example and not limitation, Figure 23 illustrates
the male
member as being molded into the pommel and the female member molded into the
front post. However, it is also contemplated that the male member and female
member may be attached to the pommel and front post via glue or any other
method
known in the art or any method discussed herein.
The above description is given by way of example, and not limitation. Given
the above disclosure, one skilled in the art could devise variations that are
within the
scope and spirit of the invention disclosed herein. Further, the various
features of the
embodiments disclosed herein can be used alone, or in varying combinations
with
each other and are not intended to be limited to the specific combination
described
herein. Thus, the scope of the claims is not to be limited by the illustrated
embodiments.
