Technical Field
[0001] The present invention relates to a backpack including shoulder belts respectively
having hook-shaped (∩-shaped) tubes. More particularly, the present invention relates
to a backpack which enables a wearer to inject air into the tubes to inflate the tubes
into the ∩-shaped form and to thus enable the backpack to tightly contact the wearer's
shoulders despite of weight of the backpack, so that the backpack is prevented from
slipping from the wearer's shoulders or from moving sideways and the wearer can feel
less pressure of the backpack to the wearer's shoulders.
Background Art
[0002] In general, because a backpack that a student mainly uses instead of a school bag
or uses for traveling or hiking contains heavy things such as books or articles therein,
the weight of the heavy backpack is transferred to the a wearer's body as it is, so
that the wearer feels too much pressure.
[0003] Particularly, because the heavy backpack imposes a heavy burden on the wearer's waist
and shoulders, it has a bad effect on the wearer's spine and increases fatigue, and
especially, threatens teenage students' health.
[0004] Moreover, because the wearer who carries the bag on the wearer's shoulders cannot
walk in a correct posture due to a severe pressure and pain on the shoulders and walks
in an awkward posture, and hence, in the case of teenagers who carry the bags on their
shoulders every day, they have several problems in that their spines are crooked or
distorted in the process of their growth and in that they may feel pains on the waist,
shoulders, or neck.
[0005] Accordingly, it is encouraged to arrange things neatly in order inside the backpack
to thereby balance weight of the backpack and to adjust the length of the shoulder
belts according to the wearer's body conditions to thereby reduce a strain on the
wearer's waist, prevent the shoulder pain and make the wearer take a balanced posture.
However, such a method is just a temporary expedient and, actually, it is not easy
to relieve the strain or pressure on the waist and shoulders, and hence, some of the
backpacks respectively have a strap for tightening the wearer's chest part to fix
the backpack to the shoulders. Alternatively, some of the wearers pull the shoulder
belts tightly with both hands so that the rear part of the backpack gets in close
contact with the wearer's back.
[0006] In the meantime, in consideration of the above-mentioned problems, shoulder pads
are respectively attached to rear faces of the shoulder belts being in contact with
the wearer's shoulders so as to relieve the pain applied to the wearer's shoulders.
However, because the shoulder pads are in a simple structure that wrapping paper is
covered and sewed on an urethane foam or a sponge, which is fit on the shoulder belts,
the shoulder pads can just relieve pain or impact on the shoulders but cannot disperse
the weight applied to the waist and shoulders when the wearer carries the backpack
on the shoulders, and hence, the conventional methods cannot solve the above-mentioned
problems.
[0007] Korean Patent No.
10-0462464 discloses a shoulder band protector for bag. In the prior art, the shoulder band
protector for bag includes: a hard cover, which wraps a tube having an injection hole
for injecting and discharging air to thereby widely wrap around the wearer's shoulder;
retaining jaws respectively fixed at both sides of an upper portion of the cover in
such a fashion that a shoulder band is located between the retaining jaws to thereby
prevent the shoulder band from being separated sideways; and male and female detachable
buckles respectively joined to the shoulder bands respectively fixed to both sides
of the retaining jaws.
[0008] As another example, Korean Utility Model Publication No.
20-1992-0005175 discloses an air-injectable type suspender for bags. The air-injectable type suspender
for bags includes: a tube pouch formed in the middle of a connection strap to which
a hook and a buckle are connected, the tube pouch having a tube insertion hole, to
which a slide fastener is attached, and a protruding injection hole; and an air tube
inserted into the tube pouch, the air tube having an air injection hole and a partition
wall.
[0009] Such prior arts have the shoulder protector of the tube type, to which air is injected,
to thereby relieve pressure of the backpack applied to the wearer's shoulders. However,
the prior arts cannot reduce a burden applied to the wearer's waist because the backpack
is not fixed to the wearer's shoulders, and hence, have a problem in that the backpacks
may cause spondylopathy or fatigue because the backpack slips down from the wearer's
shoulders due to the weight of the backpack or moves sideways.
[0010] Therefore, the backpacks according to the prior arts can relieve only the pain applied
to the top of the shoulder of the wearer where the shoulder protector touches but
cannot reduce the burden on the wearer's waist, and hence, cannot solve the problem
caused by pressure applied to the wearer's spine or clavicle.

Technical Problem
[0011] Accordingly, the present invention has been made in an effort to solve the above-mentioned
problems that a wearer's waist is bent backward or forward because the backpack is
not fixed to the wearer's shoulders and slips down and that the backpack imposes a
burden on the wearer's waist because the backpack moves sideways. Accordingly, it
is an object of the present invention to provide a backpack having a tube-type shoulder
belt having hook-shaped tubes respectively formed at upper portions of shoulder belts
so as to enable a wearer to inject air into the tubes to inflate the shoulder belt
into a hook shape and to thus enable the hook-shaped shoulder belts to tightly get
in contact with and be fixed to the wearer's shoulders without slipping down from
the wearer's shoulders and moving sideways, thereby reducing the weight of the backpack
applied to the wearer's waist and relieving heaviness of the backpack applied to the
wearer's shoulders owing to air pressure of the shoulder belts.
Technical Solution
[0012] To achieve the above objects, the present invention provides a backpack having a
tube-type shoulder belt including: a backpack body for accommodating books or articles
therein; and shoulder belts respectively having tubes, each of the tubes having an
air injection portion formed at one side thereof.
[0013] The two tubes of the upper portions of the shoulder belts may be interconnected via
a pipe.
[0014] The tubes of the upper portions of the shoulder belts of the backpack body may be
wrapped by a covering formed by sewing work, may be detachably attached to the shoulder
belts by female Velcro tape disposed on the upper portion of the shoulder belt of
the backpack body and male Velcro tape disposed on the tube, or may be respectively
inserted into spaces, which are respectively formed in the upper portions of the shoulder
belts made of fabric or the like for accommodating the tubes.
[0015] Furthermore, the shoulder belt may have an air injector for injecting air into the
air injection portion of the tube.
Advantageous Effects
[0016] The backpack having the tube-type shoulder belt according to the present invention
has hooks formed by air injected into the tubes located on the upper portions of the
shoulder straps for suspending the backpack on the wearer's shoulders so as to prevent
the backpack not from slipping down from the wearer's shoulders and moving sideways
by fixing and supporting the backpack on the wearer's shoulders, whereby the backpack
can prevent spondylopathy by reducing a burden applied to the wearer's waist and relieve
heaviness of the backpack applied to the wearer's shoulders owing to air pressure
of the tubes to thereby prevent spondylopathy and fatigue even though the wearer carries
the backpack on the shoulders for a long time because the backpack corrects the wearer's
posture.

Mode for Invention
[0018] Reference will be now made in detail to the preferred embodiment of the present invention
with reference to the attached drawings. It will be understood that words or terms
used in the specification and claims should be interpreted as having a meaning that
is consistent with their meaning in the context of the relevant art and the technical
idea of the invention, based on the principle that an inventor may properly define
the meaning of the words or terms to best explain the invention.
[0019] As shown in the drawings, a backpack having a tube-type shoulder belt includes: a
backpack body 10 for accommodating books or articles therein; two shoulder belts 20
respectively arranged on upper portions of two shoulder straps 11 of the backpack
body 10, the shoulder belts 20 respectively having tubes 22, each of the tubes 22
having an air injection portion 21 perforatingly formed at one side thereof so as
to enable a wearer to inject air into the tube so that the shoulder belt is inflated
in a hook shape to tightly get in contact with the wearer's shoulder.
[0020] The backpack body 10 is applicable to all types of bags, which students carry on
their shoulders after putting books or other articles therein, such as school bags,
bags for climbers, traveling backpacks, and others, and may be also applied to backpacks
having only one shoulder belt according to the shapes of the backpack body.
[0021] Because the shoulder belt 20 has the same hook shape as the upper portion of the
wearer's shoulder, the backpack can tightly get in contact with the entire upper portion
of the shoulder of the wearer in such a way as to be fixed on the wearer's shoulder
to prevent the backpack from slipping down or moving sideways, so that the backpack
makes the wearer take a correct posture by evenly dispersing the load of the backpack
and prevents spondylopathy and fatigue by reducing a burden applied to the wearer's
waist.
[0022] Particularly, because the shoulder belts 20 respectively have the tubes 22, when
the wearer injects air into the tubes 22 using the air injection portions 21 respectively
formed on the tubes 22, pressure applied to the wearer's shoulder is relieved due
to a damped pressure by the injected air.
[0023] As shown in FIG. 1, a pipe 30 is interposed between the tubes 22 of the two shoulder
belts 20 for connecting the tubes 22 with each other.
[0024] Accordingly, even though the air injection portion is formed on only one tube, when
the wearer inject air through the air injection portion 21, the injected air is transferred
to the tube 22 of the other shoulder belt 20 connected to the pipe 30, so that air
can be injected into all of the tubes 22 of the shoulder belts 20 to thereby enhance
usability.
[0025] Particularly, the shoulder belts 20 which are located at the wearer's shoulders and
chest part are supported by the wearer's shoulders and chest while the wearer carries
the backpack 10 on the shoulders, and hence, it enhances contactability and supportability
of the backpack 10. In this instance, because air is injected into the tubes 22, the
shoulder belts 20 provide a natural cushioning function so as not to pressurize the
wearer's shoulders and chest.
[0026] Moreover, in another preferred embodiment of the present invention, the tube 22 which
is joined to the backpack body 10 is extended to the length of the backpack body and
is joined to a back plate of the backpack, and then, the backpack can reduce pressure
applied to the user's back due to a buffering action of the tubes.
[0027] In the meantime, it is preferable that each of the shoulder belts has a covering
23 made of fabric or the like for wrapping and protecting the tube 22 and connecting
the tube 22 to the backpack body 10 and the shoulder strap 11. The tube 22 and the
covering 23 of the shoulder belt 20 may be bonded through generally used bonding work,
such as high-frequency deposition, and the shoulder belts 20 respectively having the
tubes 22 and the coverings 23 can be respectively connected to the backpack body 10
and the shoulder straps 11 through sewing work or the like.
[0028] Furthermore, the backpack body 10 further includes a female Velcro tape 10a disposed
on the rear face of the shoulder strap 11 and the shoulder belt 20 has a male Velcro
tape 20a, so that the shoulder belt 20 is detachably attached to the shoulder strap
11 via the female and male Velcro tapes 10a and 20a. Alternatively, the shoulder belt
20 may be formed in such a fashion that a space for accommodating the tube is formed
in the upper portion of the shoulder strap, which is made of fabric or the like, and
the tube 22 is inserted into the space.
[0029] In the case that the tube 22 is extended to the length of the backpack body and is
joined to the back plate of the backpack, an extension portion of the tube 22 may
be mounted inside the back plate of the backpack.
[0030] Therefore, because the shoulder belts 20 can be detachably attached to the shoulder
straps 11, as occasion demands, the wearer can attach the shoulder belts 20 onto the
shoulder straps 11 or detach the shoulder belts 20 from the shoulder straps 11 in
order to use only the shoulder straps 11, and hence, it enhances usability and convenience.
[0031] The shoulder belt 20 may further include an air injector for injecting air into the
air injection portion 21 of the tube 22. So, the wearer can conveniently increase
and decrease air pressure of the inside of the tube 22 of the shoulder belt 20 using
the air injector so as to reinforce the hook shape of the shoulder belt or to relieve
the pressure of the backpack applied to the wearer's shoulder or chest.
[0032] Additionally, if necessary, the wearer can easily discharge the inside air of the
tube 22 through the air injection portion 21, and the tube 22 may further include
an air outlet.
[0033] The preferred embodiments of the present invention are capable of being modified
and changed in various ways, but it should be understood that there is no intent to
limit the present invention to said embodiments, and it should be also understood
by those of ordinary skill in the art that various changes of the embodiments in combination
with the prior arts may be made therein within the scope of the invention as defined
by the appended claims.
