DESCRIPTION
TITLE OF INVENTION: BACKPACK
TECHNICAL FIELD
[0001] The present invention relates to a backpack (rucksack).
BACKGROUND ART
[0002] A conventional backpack includes ventilation means by which a back
plate,
which is a back-side surface constituting a storage part, does not contact
directly with the
back of a wearer. The conventional ventilation means includes a ventilation
plate of a
mesh-net material which is disposed opposite to the back plate (for example,
see Patent
Documents 1 and 2).
[0003] The ventilation plate is spaced apart from the back plate such that a
constant
space interval between the ventilation plate and the back plate is maintained
under an
elastic force by the lower fixing panel flexed in an arc shape. Such a
backpack prevents
a wearer from sweating on his back when being worn for a long time and is
useable with
comfort.

[0011] The storage part 2 includes a back plate 24 opposite to the back PB of
the wearer
P and an upper opening 2e allowing objects to be into and out of on an upper
side 2a,
which has a bag shape and is made of the other member. An upper opening 2e is
provided with a top cover 8 to cover the upper opening 2e. Upper ends and
lower ends
of vertical belts 15, 15 are sewn up and fixed with stretch to a reinforcing
cover lid and
the mesh net 10 to prevent the frame 11 from expansion in a top-bottom
direction. The
reinforcing cover 11d, which will be described later, is arranged around an
upper frame
1 lg and a lower frame lie of the frame 11. Shoulder belts 3, 3 have a widened
belt
shape and detachably attached at four points in a top and a bottom of a back-
side surface
BP.
[0012] The supporter 4 includes: the frame 11 made of a metal and arranged
along the
top, bottom, right and left of the storage part 2; the mesh net 10 attached to
the frame 11,
having a ventilation characteristic and arranged apart from the storage part
2; a pair of
ball members 13, 13 arranged in a right-left direction between the mesh net 10
and the
storage part 2, which are being attached to the frame 11 via a spring (an
elastic member)
12; and the reinforcing cover lid having an elongated bag shape (see FIG. 2).
An inside
edge of the reinforcing cover lid is sewn up along the circumference of the
frame 11 to
contain the frame 11 inside thereof.
[0013] As shown in FIG. 1 and FIG. 4, the frame 11, for example, is formed
annularly
with a tube body made of steel as a spring member. The frame 11 is composed of
some
parts including; the upper flame 1 lg arranged on the top of the frame 11; the
lower frame
lie arranged on the bottom of the frame 11; a right frame member 1 lf arranged
on the
right side of the upper frame hg and the lower frame lie; and a left frame
member 1 lf
arranged on the left side of the upper frame 1 lg and the lower frame lie.
Upper ends
11h and lli being provided on the upper frame llg are connected annularly and
integrally
to form a curved shape having approximate hyperbola and parabola. The outer
periphery of the mesh net 10 is sewn up to the inside of the reinforcing cover
11d. The
mesh net 10 is fixed with stretch by the frame 11 to form a three-dimensional
saddle-like
shape which allows the mesh net 10 to fit on the back PB of the wearer P.
[0014] The right and left frame members 1 if, 1 lf of the frame 11, as shown
in FIG. 3
and FIG. 4, are arranged in front of the right side 2d and left side 2c of the
storage part 2
respectively in a right-left direction X. The right and left frame members 1
If, 1 if are
curved with convex in Al and A2 directions being apart from the storage part 2
(a
direction toward in behind of the wearer P). The frame
11, as shown in FIG. 2 and FIG.
4, are arranged in front of the upper side 2a and the lower side 2b of the
storage part 2
respectively in a top-bottom direction Z. The upper side 2a and the lower side
2b are
4
Date Recue/Date Received 2021-03-17
87166833 CA 03113209 2021-03-17
curved in B1 and B2 directions being close to the storage part 2 (a direction
toward in
front of the wearer P). This allows the frame 11 to be a shape fitted on the
back PB of
the wearer P. In particular, the left frame member 1 if and the right frame
member 1 if
are fitted on the back PB of the wearer P and it is advantageous that the
frame 11 does
not interfere with a swing of arms during walking.
[0015] An outline of the frame 11 formed to be annular, as shown in FIG. 5, is
larger
than that of the storage part 2. The mesh net 10 is attached to the frame 11
and arranged
with stretch inside the annular frame 11. The mesh net 10 is in a mesh, is
made of a
polyester fiber for example, has a quick-drying feature, and has flexibility.
The
polyester fiber allows the mesh net 10 to fit a body of the wearer P and to
disperse a load
of the backpack 1. The mesh net 10, for example, arranged inside the annular
frame 11
via the reinforcing cover lid and stretched with curvature along the back PB
of the wearer
P.
[0016] The ball members 13. 13 are attached to the frame 11 via the spring 12.
The
spring 12 in this embodiment includes a first spring (a first elastic
member)12a and a
second spring (a second elastic member) 12b which are coil springs having the
same
length. One ends of the first spring 12a and second spring 12b are fixed to
parts of the
frame members 1 if, 1 if, the parts are convex in a direction apart from the
storage part 2.
[0017] The other ends of the first spring 12a and second spring 12b are
attached to a
pair of the ball members 13, 13 which are arranged in a right-left direction
in a row and
are connected to prevent an interval of ball members 13, 13 from widening. The
ball
members 13, 13 of the present embodiment are also formed to be sphere and are
supported
to be rotatable in a front-rear direction with a supporting axis of the spring
12 being a
rotational center. The ball member 13 may be preferably smaller than a tennis
ball and
larger than a table tennis ball, further may be preferably a sphere made of
wood in about
the size of a golf ball.
[0018] The ball members 13, 13, as shown in FIG. 2, are arranged between the
mesh net
and the storage part 2 when the supporter 4 and the storage part 2 are
assembled. The
first spring (the first elastic member) 12a and the second spring (the second
elastic
member) 12b bias the ball members 13, 13 in a direction to press the mesh net
10. That
is, the ball members 13, 13 press the back PB of the wearer P via the mesh net
10 with a
tension of the spring 12.
[0019] The back plate 24 of the storage part 2, as shown in FIG. 4, is
provided with a
lateral belt 16 in a right-left direction X. The lateral belt 16, as shown in
FIG. 1, is
inserted to be movable between the vertical belts 15, 15 and the back plate 24
of the
storage part 2. The lateral belt 16, as shown in FIG. 5, also allow the
storage part 2 to
5
Date Recue/Date Received 2021-03-17
87166833 CA 03113209 2021-03-17
move in a swing direction U and restricts the storage part 2 to move behind
the wearer P
(in a B2 direction) as shown in FIG. 2.
[0020] The frame 11, as shown in FIG. 5, locks and releases a locknut 1 la
arranged
between a pair of the upper ends 11h, lli to and from a screw part lib
arranged opposite
to the locknut 1 la. A hanging ribbon 9 is attached to a center of the upper
side 2a of the
storage part 2. The hanging ribbon 9 is also hanged on a neck part of a belt
insertion
part 17 to hang the storage part 2 on a center of a right-left direction X of
the frame 11.
A width of the belt insertion part 17 is formed to be larger than that of a
ribbon ring 9a of
the hanging ribbon 9 being hanged.
[0021] The shoulder belts 3, 3. as shown in FIG. 1, is inserted being crossed
in a X shape
into the belt insertion part 17 of the frame 11. The lower parts of the
shoulder belts 3, 3
are inserted into annular ring parts 11c, 11c respectively which are formed at
right and
left ends of lower parts of the frame 11. The upper ends and the lower ends of
the
shoulder belts 3, 3 are provided with carabiners 22, 22, respectively. Front
parts of an
upper part and a lower part of the storage part 2, as shown in FIG. 2, are
provided with
locking parts 20, 20 having locking rings. Both the upper and lower carabiners
22, 22
are detachably locked with the locking rings of the locking parts 20, 20,
respectively.
[0022] Changing the length of the shoulder belts 3, 3 adjusts a position of
the storage
part 2 in a top-bottom direction Z according to a body shape of the wearer P.
When
changing the length of the shoulder belts 3, 3, the right and left frame
members 1 lf, 1 if
of the frame 11 keeps the mesh net 10 in close contact with right and left of
body sides
PW of the wearer P to hold body sides PW. Thus, a position of the ball members
13, 13
does not shift from a point in backbones F of the wearer P in top-bottom and
right-left
directions, which has a better massaging effect, and the ball members 13, 13
contact with
a proper position to apply an appropriate stimulation.
[0023] Next, functions and effects of the backpack 1 of the present embodiment
will be
described. The backpack 1 of the present embodiment has a pair of the first
spring 12a
and the second spring 12b arranged in a right-left direction and disposed
between right
and left frames 1 if, 1 lf formed to be curved. When the wearer P wears the
backpack 1
of the present embodiment on the back PB, the first spring 12a and the second
spring 12b
arrange the ball members 13, 13 to a point where the ball members 13, 13
contact with
on a desired point of the center of the back PB. The ball members 13, 13 press
around
the backbones F in a condition where the mesh net 10 intervenes as a cushion.
[0024] The ball members 13, 13, as shown in FIG. 5, are arranged between an
eighth
thoracic spine F8 and a tenth thoracic spine F10 of the wearer P to press the
backbones F
accurately from right and left, for example, like pressing with a pad of a
thumb. The
6
Date Recue/Date Received 2021-03-17
87166833 CA 03113209 2021-03-17
ball members 13, 13 press a desired part of the wearer P almost equally from
right and
left to stimulate the desired point, thus the wearer P expects a health-
promoting effect.
When pressing the backbones F, the ball members 13, 13 contact with the back
PB in a
condition where the mesh net 10 intervenes as a cushion to reduce an impact
relative to
contacting with the backbones F directly.
[0025] When the ball members 13, 13 receive a separating force, the first
spring 12a and
the second spring 12b expand and absorb the force to prevent the ball members
13, 13
from separating each other. This reduces a position shift of the ball members
13, 13 in
a right-left direction X, and the ball members 13, 13 contact accurately with
the point
having a better massaging effect.
[0026] With adjusting a force of sliding and contacting between the ball
members 13,
13 and the mesh net 10, the ball members 13, 13 contact with the mesh net 10
along the
backbones F having a roughness in a top-bottom direction Z (see FIG. 5). This
rotates
the ball members 13, 13 in a vertical direction and gives a better stimulation
to nerves
between the eighth thoracic spine F8 and the tenth thoracic spine F10.
[0027] The right and left frame members 1 if, 1 if of the frame 11, as shown
in FIG. 4,
are curved apart from the storage part 2 and curves around in front directions
of Al and
A2 of the wearer P. The supporter 4 keeps the mesh net 10 to contact firmly
with a large
area of body which are from the back PB to the right and left body sides PW of
the wearer
P. The frame 11 is formed with a spring member having elasticity. This makes
the
frame members 1 if, 1 if to be curved around in Al and A2 directions toward in
front of
the wearer P, also makes an upper side and a lower side of the frame 11 to be
curved in
B1 and B2 directions being close to the storage part 2 toward behind the
wearer P. As
a result, when the mesh net 10 contacts with the body, the supporter 4 fits
various body
shapes to bring a better holding property. In particular, the ribbon 9 hanged
on the belt
insertion part 17 brings a weight of the backpack 1 to the frame 11 foimed by
a spring
member, and the upper frame hg and the lower frame lie curves in B1 and B2
directions
toward behind the wearer P, respectively. Thus, the frame members 1 if, llf
further
come closer to the right and left body sides PW (see FIG. 5) and are curved
around in
directions of Al and A2 toward in front of the wearer P to improve sense of
fit.
[0028] As shown in FIG. 5, the supporter 4 is curved in B1 and B2 directions
being
close to the storage part 2 at the upper side 2a and the lower side 2b of the
storage part 2.
The supporter 4 also makes the mesh net 10 to contact firmly and widely with
the back
PB of the wearer P being curved with convex in a side view. In particular,
around a
lumber of the wearer P, a part having a wide shape and widened in a right-left
direction
of the mesh net 10 is contacted with an upper lumber, and the mesh net 10
curves around
7
Date Recue/Date Received 2021-03-17
87166833 CA 03113209 2021-03-17
and contacts with the upper lumber to disperse a load come from the storage
part 2. This
prevents the supporter 4 from being uneven load and reduces a physical burden
of the
wearer P. An outline of the annular frame 11 is larger than that of the
storage part 2.
This allows an area of the mesh net 10 contacted firmly with the body of the
wearer P to
expand regardless of a size of the storage part 2, thereby dispersing a weight
of the
backpack 1 to wear.
[0029] As shown in FIG. 2, a distance is formed between the ball members 13,
13 of the
backpack 1 and storage part 2 to have a three-layer structure. This structure
allows the
back-side surface BP of the back plate 24 of the storage part 2 not to contact
with the back
PB directly, thereby passing air through mesh net 10 and dissipating heat.
When the
back plate 24 of the storage part 2 facing to the wearer P (see FIG. 2) is
close to the mesh
net 10, the ball members 13, 13 placed between the back plate 24 and the mesh
net 10
contacts with the back-side surface BP, thus the distance is maintained, and a
ventilation
improves. The back plate 24 is apart from the curving back PB and even if the
back PB
bends, the storage part 2 is hard to be deformed. The storage part 2,
therefore, efficiently
receives electric devices such as a tablet or a laptop computer, which might
be damaged.
[0030] Receiving objects having appropriate weight of 1 to 5 kilograms,
preferably 2.5
kilograms in the storage part 2 appropriately adjusts a force where the ball
members 13,
13 press a part between the eighth thoracic spine F8 and the tenth thoracic
spine F10 of
the wearer P. The storage part 2, as shown in FIG. 2, pulls shoulders PS of
the wearer
P in a behind direction of B1 with a position of the ball members 13, 13 as a
fulcrum to
be better for a round back.
[0031] The supporter 4 having a better holding property is hard to be shifted.
As
shown in Fig. 5, this allows the storage part 2 to move relatively in a swing
direction of
U where swing center is the ribbon ring 9a hanged on the belt insertion part
17 while the
ball members 13, 13 still contact with a desired point. A movement of the
storage part
2 in a swing direction of U whose swing center is the hanging ribbon 9 may be
measured
with a measuring instrument such as an angle sensor and a measured data may be
transferred to the wearer P's smart phone.
[0032] The backpack 1 of the present embodiment easily and removably attaches
the
storage part 2 to the supporter 4. It is easy to determine a position between
the storage
part 2 and the supporter 4. When the storage part 2 is attached to the
supporter 4 after
the storage part 2 is removed from the supporter 4, the ball members 13, 13 is
arranged
at the same position. A knapsack or a backpack having a different shape from
the
storage part 2 can be attached to the supporter 4 according to a purpose of
use. When
the wearer P wears the backpack 1 again after putting it off, the ball members
13, 13 are
8
Date Recue/Date Received 2021-03-17
87166833 CA 03113209 2021-03-17
arranged at the same position and the wearer P obtains the same massaging
effect.
[0033] The locknut 1 la and the screw part 1 lb, as shown in FIG. 4, are
fastened together
after a pair of the upper ends 11h, 11h is inserted into the hanging ribbon 9
attached to an
upper part of the storage part 2. The belt insertion part 17 is larger than
the ribbon ring
9a. This allows the hanging ribbon 9 to be hard to come off from the belt
insertion part
17 and further to support the storage part 2 stably.
<Example of Modification>
[0034] A backpack 101 as a modification example will be described with
reference to
FIG. 6. Note that the same parts or equivalent parts as the backpack 1 in the
present
embodiment will be described with the same numerals. The backpack 101, as
shown in
FIG. 6, includes: a storage part 102; a pair of shoulder belts 3, 3 attached
to the storage
part 2; and a supporter 104. The supporter 104 is attached to a back PB of a

direction of X is
inserted into the lower frame insertion part 112.
[0037] Next, functions and effects of the backpack 101 as the modification
example will
be described. In the backpack 101 as a modification example, which is
described above,
the storage part 102 is connected integrally with the supporter 104 and is
hard to move,
in addition to having the same functions and effects of the backpack 1 in the
above-
described embodiment. The other configuration, functions and effects are the
same or
equivalent as the backpack 1 in the embodiment and descriptions are omitted.
[0038] The present invention is not limited to the embodiments described above
and
allows various modifications. The embodiments described above are the examples
for
explaining the invention in an easy-to-understand manner and are not limited
to

9
Date Recue/Date Received 2021-03-17
87166833 CA 03113209 2021-03-17
another embodiment. Possible
modifications based on the above-described
embodiments will be described below.
[0039] The embodiments have been described to show that the backpack 1
includes the
storage part 2 having a bag shape and the upper opening 2e, arranged on the
upper side
2a, which is able to be opened and closed by the top cover 8 which allows
objects to be
taken in and out. Not limited to this, the invention may use any kind of
shapes, a number
and materials to form a backpack as long as they are supported by the
supporter 4 such as
a knapsack, a backpack having a different shape from the storage part 2.
[0040] The embodiments have been described to show that the storage part 2 and
the
supporter 4 of the backpack 1 are separatable with the removable shoulder
belts 3, 3.
However, not limited to this, the storage part 2 and the supporter 4 may be
separatable
with the shoulder belts 3, 3 having another separatable point, for example,
such that the
shoulder belts 3, 3 separates in a middle of the strap. The backpack 101 as
the
modification example has been further described to show that the storage part
102 and
the supporter 104 are combined with the upper and lower frame insertion parts
111, 112.
However, not limited to this, for example, the storage part 102 and supporter
104 may be
combined with another connecting point.
[0041] The mesh net 10 may have any mesh size as long as the mesh net 10 has a
ventilation characteristic and may combine some kinds of meshes having
different mesh
sizes. The mesh net 10 may have stretchiness and any kinds of materials may be
used
as long as the mesh net 10 fit a body shape of the wearer P. Note that a range
of attaching
the mesh net 10 is not limited to an entire area inside the frame 11, for
example, the range
may be between a pair of right and left vertical belts 15, 15, or a part of
inside the frame
11. A shape of
the mesh net 10 and a place to which the mesh net 10 is attached are not
limited to as long as the mesh net 10 is attached to the frame 11 so that the
storage part 2
having a bag shape such as a knapsack does not contact directly with the ball
members
13, 13 or the mesh net 10 through between the vertical belt 15.
[0042] The embodiments have been further described to show that the frame 11
is
configured to connect annularly frame members 1 if made of a metal each other,
but not
limited to this. The frame member, for example, may connect each other to form
rectangular, ellipse or oval and may be configured to use a carbon fiber
material. A
number, a shape and a material of the frame 11 are not limited. The frame 11
may be
configured with not only a tubular member but also a solid member and may have
springiness having elastic modification at from 5 to 10 kilograms.
[0043] The spring 12 as an elastic member is not limited to a shape of the
spring 12 of
the present embodiments. The spring 12 may form in a cater-corner such as a
radial
Date Recue/Date Received 2021-03-17
