Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the two tubes of the upper portions of the shoulder belts may be interconnected via a pipe.
  • 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.
  • the shoulder belt may have an air injector for injecting air into the air injection portion of the tube.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • a pipe 30 is interposed between the tubes 22 of the two shoulder belts 20 for connecting the tubes 22 with each other.
  • 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.
  • 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.
  • the shoulder belts 20 provide a natural cushioning function so as not to pressurize the wearer's shoulders and chest.
  • 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.
  • 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.
  • 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.
  • 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.
  • an extension portion of the tube 22 may be mounted inside the back plate of the backpack.
  • 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.
  • 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.
  • 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.
