DESCRIPTION

BACKGROUND OF THE INVENTION
1. Field of the Invention

The present invention relates to a body elongator, and in particular to a body
elongator comprising a lower body stretching and elongating structure that can
aid to stretch the muscles, providing warm up for exercises, and to prevent
muscle cramps. It is convenient for carrying since the two structures can be
folded inside a frame.

2. The Prior Arts

Body stretching is mainly to enhance the mobility of the joints, and able to
maintain the muscle in a certain length and proper flexibility. Body
stretching
is required under many circumstances, such as, for example, for the elderly
who need to stretch their muscles and tendons, and bones, office workers
having to sit for extended durations, people feeling tired because of the body
weight stresses exerting on spines, teenagers who wanted to be simulated for
additional growth, and patients who need rehabilitation after surgical
operations. In addition, body stretching sometimes can be used as a method
for warm up of the body before exercising, such as for preventing and
alleviating muscle cramps of the track runners, swimmers, and ballet dancers.
At present, irregardless of whether it is the body stretcher sold on the
market
for physical fitness or the body stretching device provided in hospitals for
rehabilitation, they are all bulky and structurally complicated. As an
example,
U.S. Patent No. 4,826,158 discloses leg-stretching and exercising equipment,
which is one such classic example. This type of equipment has many
disadvantages, such as having a complicated structure that is inconvenient for
reassembling and disassembling, and thus cannot be easily carried, and are
mostly disposed at stationary locations. As a result, in one aspect, the user
would require to first have enough perseverance, and to arrange time to do the
body stretching at a specified location. Furthermore, the effectiveness of
1

-. ,
CA 02582093 2008-10-28

body stretching is negatively affected because of limited usage time. In
addition, due to the
excessive size of the device, the user may feel intimidated, and refuse to use
it. Accordingly, for
those who require to do body stretching everyday, a compact and portable body
elongator is
necessary.

Apart from the above-mentioned drawbacks due to structural complexity, the
conventional body
stretching equipment only provides a leg stretching function, which has less
added value, and is
much more uneconomical for manufacturers and consumers alike.

SUMMARY OF THE INVENTION

According to the invention there is provided a portable traction device, which
includes a
base, a body elongator housed ort the base, the body elongator having a
support for ankles on
the base. A toe bar having a cylinder rotatably mounted to two carrier posts
connected to
opposite sides of the base is moveable from a retracted position adjacent the
base to an
extended position in which the cylinder is positioned to engage the toes of a
user and stretch a
user's Achilles tendon and calf muscle groups.

Preferably a cover is hingedly attached to the base and, when in a closed
position,
encloses the body elongator and is locked to the base, and when in an open
position, exposes
the body elongator for use.

The cover has two sections hinged together for closing the open top and the
open end of
the base, respectively. The cover is hinged to the base, and is positionable
underneath a
bottom of the base.

A heel rest supports ankles of a user and secures straps operative to fasten a
user's
ankles down to respective ones of the heel rests. The heel rests are slidable
relative to the base
so as to pull on the legs of a user.

The securing straps are hook and loop fasteners which engage corresponding
hook and
loop fasteners on the heel rests.

The base has two opposite sidewalls, a guide bar mounted to each end of the
heel rest
and carrying at least one roller movably received in the slide rail whereby
the heel rest is
movable with respect to the base while the roller moves along the slide rail.

2


CA 02582093 2008-10-28

A driving mechanism is coupled to the heel rest, and is operative to drive the
heel rest so
as to place a user in traction.

The case made up of the base and the cover has a size substantially
corresponding to a
laptop computer. To operate, the cover is unfolded underneath the bottom of
the base, serving
as a base board stably disposed on a fixture surface, such as a bed, and if
desired, the toe bar
is moved upward beyond the base. To pack, the toe bar is laid flat back into
the base, and the
steel cable is wound up, and, together with the driving mechanism, is placed
inside the base
within a space between the ankle support slide and the toe bar, and thus
providing easy
carrying and storage convenience after the base is closed by the cover.

In comparison with known body stretchers, the present invention is small and
highly
portable. A user is able to adjust the desired degree of stretching of the
muscle groups before
sleeping, so as to allow the body to be stretched in a smooth continuous
manner whether the
user is asleep or awake.

The driving mechanism includes a steel cable having an end connected to a
flexible rope
windable around a reel shaft and an opposite end extending through a hole
defined in a stop
mounted to the base and connected to said heel rest.

The driving mechanism includes two racks mounted to respective sides of the
heel rest,
two pinions engageable with respective ones of the racks, and two motors
mounted on the base
and operative to drive the pinion and move the heel rest.

The carrier posts have a plurality of mounting holes to selectively engage the
ends of the
toe bar for adjusting the location of the toe bar along the length of the
carrier posts.

The toe bar has an elongated shaft extending between the carrier posts, first
and second
gears mounted to the elongated shaft, and first and second motors mounted to
the base and
operative to drive third and fourth gears engaging the first and second gears,
respectively,
whereby operation of the motors selectively moves the toe bar between a
horizontal and vertical
position.

DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to the drawings and in particular to Figure 1, a body elongator
constructed in
accordance with the present invention comprises a case, generally designated
with reference
numeral 3, in which an accommodation space is defined. The body elongator also
comprises a
heel elongator I and a calf stretcher 2, both being arranged inside the case 3
to make a
compact construction that allows for easy carrying and transportation.

The case 3 comprises a base 31 having-a suitable size, such as three inches in
height, fourteen
inches in both length and width, to accommodate the heel elongator 1 and the
calf stretcher 2.
The base 31 has an open top for a user's access of the heel elongator 1 and
the calf stretcher 2
and an open proximal end through which the user's feet may extend for being
treated by the
heel elongator 1 and the calf stretcher 2.

A cover 32 is attached to the base 31 with hinges 33. The cover 32 is composed
of two boards
connected with hinges 33 and the two boards are respectively corresponding to
the open top
and open end of the base 31 for selectively opening and/or closing the open
top and open end
of the base 31.

Also referring to Figure 2, when the case 3 is opened for use, the cover 32 is
folded under the
bottom of the base 31, serving as a base board and exposing the open end of
the base 31, so
as not to obstruct the movement of the user's feet. If desired, a handle 34
(see Figure 8) may be
attached to the base 31 for hand carrying. A plurality of engagement snaps 36
(see Figure 1) is
provided on the base 31 on opposite sides of the handle 34. The cover 32
further comprises a
snap latch hinge 35 for engaging with the latch, such that the case 3 is
secured when the cover
32 is closed to allow for easy carrying and transportation and storage.

Also referring to Figure 2, the cover 32 is hinged to the base 31 and can be
unfolded
underneath the bottom of the base 31. The two-board structure allows the cover
32 to expose
the open end of the base 31 when the cover 32 is unfolded under the bottom of
the base 31 and
the heel elongator I that is arranged inside the base 31 can be seen.

The heel elongator 1 comprises a leg support slide 11 movable in a
longitudinal direction of the
base 31 and having two lateral ends adjacent to opposite sidewalls of the base
31. Preferably,


CA 02582093 2008-10-28

a one-inch gap is present between the leg support slide 11 and the sidewall of
the base 31.
Slide guide means comprising a slide rail 12 and a guide bar 121 is provided
between each
lateral end of the leg support slide 11 and the corresponding sidewall of the
base 31 for guiding
movement of the leg support slide 11 with respect to the base 31. The guide
bar 121 is
mounted to the lateral end of the leg support slide 11 and longitudinally
extends in a direction
into the base 31. Rollers 122 are mounted to the guide bar 121. The slide rail
12 comprises an
elongated slot defined in the sidewall of the base 31 and movably receives the
roller of the
guide bar 121 to guide longitudinal movement of the leg support slide 11 with
respect to the
base 31.

The leg support slide 11 further comprises a hook 19 (see Figure 4A) disposed
at ;a bottom
surface thereof, and the base 31 comprises another hook 19 at the surface
thereof. A spring
191 has two ends respectively fixed to the hooks 19. An attachment stop 15 is
mounted to a
bottom surface of the base 31 at a location away from the leg support slide
11.

The leg support slide 11 is of a box-shape, having a top in which two arc
recesses 111 are
defined to serve as heel rest portions. Leg fastener means is provided in each
heel rest portion
111, comprising a first portion 112 fixed in the heel rest portion 111 and a
separate second
portion 141 that is releasably engageable with the first portion 112 to secure
a user's leg there
between when the leg is positioned in the heel rest portion 111. In the
embodiment illustrated,
the leg fastener means are made of hoop and loop fastener strips and the first
portion 112 of the
leg fastener means comprises a female hoop and loop fastener piece, while the
second portion
141 comprises a male hoop and loop fastener piece. Preferably, the male hoop
and loop
fastener piece 141 is carried by a fastening band 14.

A driving mechanism is provided for driving the leg support slide 11 with
respect to the base 31.
In an embodiment, the driving mechanism is a manually operated mechanism, as
shown in the
embodiment illustrated in Figure 2. The manually operated driving mechanism,
which is
generally designated with reference numeral 14 in Figure 2, comprises a steel
cable 131
wrapped by a protective tubular sheath 132. The steel cable 131 has an outer
end connected to
a flexible rope 133 and an opposite inner end extending through a hole (not
labeled) defined in
the attachment stop 15 and fixed to the leg support slide 11. The flexible
rope 133 is enclosed
by a protective tube section 134 and is further wound around a reel shaft 135
that has a wing
nut like end portion for hand operation. The reel shaft 135 cooperates with a
locking pin 136.

6


CA 02582093 2008-10-28

To drive the leg support slide 11, the reel shaft 135 is manually rotated with
the wing nut like
end portion to wind the flexible rope 133 and the steel cable 131 drives the
leg support slide 11
toward the attachment stop 15. As a result, the spring 191 is stretched along
with the
movement of the leg support slide 11.

Alternatively, the driving mechanism can be a power device. Figure 3 shows a
power-operated
driving mechanism in accordance with another embodiment of the present
invention, which
comprises two motors 16 and two sets of racks and pinions 17, which are
preferable of the
same specifications. The motors 16 are fixed to the base 31 and have spindles
161 carrying the
pinions 172 respectively. The racks 171 are fixed to the leg support slide 11,
preferably at a
bottom surface of the leg support slide 11, and are engageable with the
pinions 172. When the
motors 16 are in operation, the pinions 172 are rotated in either forward or
reverse directions to
move the racks 171 and thus the leg support slide 11 forward or backward
inside the base 31.
The moving distance of the leg support slide 11 is limited to the length of
the rack 171.
Referring to Figures 2, 4A and 4B, elongating the heel or body of a user with
the heel elongator
I is realized by longitudinally moving the leg support slide 11 with respect
to the case 3, which
in operation, is made stationary by placing on a fixture surface, with the
driving mechanism 13.
Legs of the user are put into the case 3 with the ankle resting in the
recesses 111 and secured
by the leg fastener means. In the embodiment illustrated, the male hoop and
loop fastener
pieces 141 of the fastening bands 14 is put in engagement with the female hoop
and loop
fastener pieces 112 to tightly secure the ankles to the leg support slide 11.
The reel rotating
shaft 135 is then manually rotated to wind the flexible rope 133 thereon,
thereby pulling the steel
cable 131 to drive the leg support slide 11 longitudinally. With the linear
movement of the leg
support side 11, heels secure to the leg support slide 11 are thus stretched
(Figure 4B shows
the legs after stretching). When the leg support slide 11 is moved to a
desired position, the
locking pin 136 is put into a positioning hole (not labeled) defined in the
reel shaft 135 to secure
the reel shaft 135 and thus fixing the leg support slide 11 in said desired
position with respect to
case 3. At this time, the spring 191 is stretched.

To terminate the leg stretching, the locking pin 136 is released, and the leg
support slide 11 is
then returned to the original, un-stretched position by the springing force of
the spring 191.
Alternatively, the legs can be simply released and lifted by separating the
male hoop and loop
fastener pieces 141 from the female hoop and loop fastener pieces 112.

7


CA 02582093 2008-10-28

Referring to Figure 3, the power-operated driving mechanism comprises a switch
18 for
controlling the actuation of the motors 16. Thus, the user, once having his or
her ankles
secured to the leg support slide 11, operates the switch 18 to actuate the
motors 16 for inducing
movement of the leg support slide 11 to the desired position to effect
elongation of heels.

With reference to Figure 5, besides the heel elongator 1, the body elongator
in accordance with
the present invention additionally comprises a calf stretcher 2 arranged in
the base 31 of the
case 3.

The calf stretcher 2 comprises a toe bar 22, having a diameter of about 4
centimeters, rotatably
supported by two carrier posts 21 located on opposite ends of the toe bar 22.
A plurality of
aligned holes 211 is defined in and distributed along the carrier posts 21 to
selectively engage
the ends of the toe bar 22 for adjusting the height of the toe bar 22 with
respect to the base 31.
The carrier posts 21 are pivotally coupled to the sidewalls of the base 31 to
allow the carrier
posts 21 to rotate between a horizontal stowed position inside the base 31 and
a vertical
erected position. Two hook rings 212 are respectively provided on the carrier
posts 21 and
sidewalls of the base 31. When the toe bar 22 is rotated to the vertical
position with respect to
the base 31, a supporting rod 213 with hooks disposed at opposite ends thereof
is provided to
secure the toe bar 22 at the vertical position by clasping the hooks with the
hook rings 212.

To stow the calf stretcher 2 when it is not in use, the carrier posts 21,
together with the toe bar
22, is rotated to the horizontal position to bring the toe bar 22 back into
the base 31, preferably
at a location opposite to the leg support slide 11. When the calf stretcher 2
is called upon for
use, the bar 22 is manually rotated with the pivotal joint of the carrier
posts 21 with the case 3
as rotation center from the horizontal position to the vertical position along
a circular path.
Alternatively, as shown in Figure 6, the toe bar 22 can be of power driving to
move from the
horizontal position to the vertical position. The power driving of the toe bar
22 is realized by a
power driving mechanism comprising a long shaft 23 extending between and
connected to the
carrier posts 21 that are pivoted to the sidewalls of the base 31. The first
gears 24 are mounted
to the long shaft 23. The two first gears 24 are preferably identical and
spaced from each other
by a proper distance. The driving mechanism further comprises two motors 26
fixed in the base
31 of the case 3. Each motor 26 has a spindle (not labeled) to which a second
gear 27 is
mounted and engageable with the respective first gear 25. When the motors 26
are actuated,
the second gears 27 are rotated either forward or backward and drive the mated
first gears 24
to induce rotation of the long shaft 23, together with the carrier posts 21
and the toe bar 22

8


CA 02582093 2008-10-28

attached to the long shaft 23, about the pivotal joint of the carrier posts 21
with the sidewalls of
the base 31. To control the rotational angular range of the carrier posts 21
and the toe bar 22,
the number of rotations of the gears 27 (or 24) is set in advance, or
alternatively, a limit switch
(not shown) is applied, such that the toe bar 22 can move repeatedly within
the predetermined
angle.

Referring to Figure 7, to operate the calf stretcher 2, the carrier posts 21
are moved, either
manually or by power, from the horizontal position to the vertical position,
by rotating about the
pivotal joint of the carrier posts 21 to the base 31. To stabilize and provide
support for the
carrier posts 21 when the user's toes are placed on the toe bar 22, the
supporting rod 213 is
employed by clasping the two hooks of the supporting rod 213 with the hook
rings 212 on the
two carrier posts 21 and on the base 31, respectively. When a user lies on his
or her back on a
horizontal surface, preferably in the bed, with the toes tightly leaning
against the toe bar 22 and
the heel secured on the leg support slide 11 making the feet exhibit plantar
flexion along the
movement direction of the leg support slide 11 to gently pull down on the
user's leg, the Achilles
tendon and the calf muscles groups can thus be stretched to prevent the calf
cramps.

After use, the toe bar 22 is moved back into the base 31 of the case 3. In
addition, the steel
cable 131 and the driving mechanism 13 are put back into the base 31 at a
location between the
leg support slide 11 and the toe bar 22. The cover 32 is put on the base 31 to
close the case 3
and the whole device can be conveniently carried and stored, as illustrated in
Figure 8.

Although the present invention has been described with reference to the
preferred embodiments
thereof, it is apparent to those skilled in the art that a variety of
modification and changes may
be made without departing from the scope of the present invention which is
intended to be
defined by the appended claims.
