Description

DETAILED DESCRIPTION OF THE INVENTION The present invention comprises a bag body made of cloth, a generally rigid frame whose portion protrudes into the pocket of the bag body and engages with the bag body, and a length-adjustable backrest and shoulder straps. The present invention relates to a backpack with an adjustable harness having a hip belt.

The backrest is provided with a waist pad and at least one shoulder pad to reduce fatigue of the user. When carrying a fully loaded backpack correctly, approximately 70% of the load is transmitted through the hip belt, and this condition is the most comfortable and efficient way to support the load. Therefore, the scapular pad primarily serves only to stabilize the load. The closer the load is to your back, the more efficiently you can support heavy objects.
Adjust the shoulder straps for this purpose.

As is clear from the above description, it is extremely important to determine the length between the lumbar pad and the scapula pad in accordance with each individual's torso length in order to reduce fatigue and load support efficiency. Up until now, Riyutsukusatsuku have been made based solely on body length. Recently, however, two types of adjustable trunk lengths have appeared on the market.
These are called one-size bags and have the commercial advantage of reducing inventory for retailers compared to previous bags. Furthermore, they have become attractive to hikers because they can be used comfortably and efficiently by two or more people, allow growing young people to adjust the weight as they grow, and are easy to resell. There is.

Among the known types of shoulder straps that can adjust the length between the shoulder pad and the waist pad, one has a shoulder pad that is approximately V-shaped in outline and also forms the upper part of the shoulder strap, and one strap is V-shaped. is attached by a fastener to the apex of and extends downwardly from there. The strap extends down the center of the bag body and passes behind a transverse web sewn into the bag body in the form of a ladder. Raising and lowering the shoulder pad can be accomplished by removing the fastener and reattaching the strap to the upper or lower web.

Therefore, this structure allows only stepwise adjustment. Moreover, the adjustment work is time-consuming and cannot be done while carrying the backpack.

The other type of barrel length-adjustable jacket has ratchet-like strips suspended from it. The scapular pad is attached to the plate and the position of the pad can be adjusted by optionally engaging a ring member in vertically aligned notches in the strip. In this case as well, it is impossible to make adjustments while carrying the backpack on your back.
Furthermore, this structure has the disadvantage that the shoulder pad can only be adjusted at fixed intervals. In other words,
Only gradual adjustments are possible.

The main object of the present invention is to provide a rearrest of the type mentioned at the beginning, in other words, it is possible to steplessly and continuously adjust the length of the backrest part of a harness with shoulder pads and waist pads. To provide a reloading device that allows adjustment operations to be performed simply and quickly.

Although the length of the hipbelt can be adjusted in the conventional way by using one or more buckles in the known backpack, it is not possible to adjust the position of the pads on the hipbelt to suit the body physique, gender, and waist circumference.

Accordingly, a second object of the present invention is to provide a backpack whose hip belt can be easily adjusted according to the user's physique and preferences.

A principal object of the present invention is to form a frame portion by at least one generally rigid frame, a portion of which protrudes into the pocket of the bag body and engages the bag body, a length-adjustable backrest portion, a shoulder In a backpack with a harness including straps and a hip belt, the frame is formed by at least one generally vertical bar and a transverse plate slidable on the bar, and the back rest is provided with at least one scapular pad, This can be achieved by providing the shoulder pad on a slidable plate.

Preferably, the plate is attached to at least one runner so that the runner is in direct contact with the bar and can be moved to any position on the bar.

In order to easily adjust the position of the plate while carrying the backpack, it is preferable that the transverse plate or runner is provided with a hanging strap that can be pulled down.

According to the above configuration, the upper and lower positions of the shoulder pads are 11
Can be adjusted over cm.

According to an embodiment, the frame is provided with two generally parallel bars, with both a slidable plate and a waist plate extending between the bars to support the bars in a spaced apart manner. The lumbar plate can be connected to a vertical bar, but this is not required. In fact, in the embodiment, the waist plate is simply attached to a web pocket into which the lower end of the vertical bar enters.

It is most preferable for the waist pads to be diamond-shaped in the upright position. This will fit snugly into the hollow of the user's lower back and minimize pressure on the surrounding muscles.

The second object is to provide a hip belt with a flexible plate to which a hip pad is attached, and to adjustably attach the flexible plate to both sides of the hip plate.
This can be achieved by making it possible to adjust the hip pads to the optimal position.

In order to adjustably attach the flexible plate, holes are provided on both sides of the hip plate, a plurality of corresponding holes are provided in a row on the plate of the hip belt, the holes are aligned with each other, and pegs are inserted.
It is simple if the plate can be attached to the lumbar plate at any position by means of pegs.

The hip pad can be adjusted not only in its longitudinal position but also in its angular position. According to the above configuration, the hip belt can be adjusted over a total of about 16 cm.
Generally, the smaller the waist size, the larger the hip angle. The above hip belt can be adapted to a wide range of pelvic shapes,
It can be fully adapted to 95% of male and female users.

Most preferably, the adjustable plate, waist plate, and hip belt plate are all made from a material that has some flexibility, such as polypropylene.

Next, embodiments will be described with reference to the drawings.

In FIG. 6, the bag according to the embodiment of the present invention includes a cloth bag body 10 and a generally rigid frame 11.
and an adjustable harness 12. The frame 11 consists of a pair of flat aluminum bars 13. Both bars 13 are connected to the bag body 10
It engages web pockets (not shown) located at appropriate locations on the upper and lower ends of the outer rear wall of the holder, and are generally parallel and perpendicular to the rear wall. A plurality of bars 13 extend on the back side of the belt-shaped retaining web and are, of course, removable from the bag body 10. As shown in FIG. 1, the frame 11 is also provided with a waist plate 14 made of polypropylene. The waist plate 14 extends across the lower portion of the bar 13 and is held in place by, for example, stitching in the lower web pocket. A diamond-shaped waist pad 15 is attached to the center of the waist plate 14. A further polypropylene transverse plate 16 is provided as the third element of the frame 11. The horizontal plate 16 is located above the waist plate 14 and is slidably attached to both bars 13. A transverse plate 16 is also shown in FIG.

Each bar 13 serves as a rail for two runners 17. Upper runner 17 on both left and right sides
is attached to the horizontal plate 16 by a web portion. This web portion extends downward on both the left and right sides to form a lower strap 30. The lower strap 30 is attached to the bag body and its length can be adjusted by means of a buckle (not shown). As shown in FIGS. 2 and 4, a pair of shoulder pads 18 are attached to the slidable transverse plate 16. The two upper and lower runners 17 are connected by a strap 19, respectively. Strap 19
The end of the shoulder strap hangs down to a height that is easy for the person carrying the backpack to grasp, thereby allowing the shoulder pad 18 on the horizontal plate 16 to be lowered to the optimum position on the user's back. The runner 17 engages the aluminum bar 13 in a generally intimate manner so that it slides along the bar 13 when an external force is applied, but otherwise remains securely stationary at a desired position on the bar 13. ing.

As shown in FIGS. 2 and 6, the adjustable harness 12
Also provided is a pad-shaped shoulder strap 20 extending from the upper end of the shoulder pad 18. The shoulder straps 20 are attached to the upper end of the backpack by adjustable balancer straps 21, which allow the load to be placed as close as possible to the user's shoulder bones and to maximize load transfer efficiency. The padded shoulder straps 20 are also attached to the bottom of the backpack in the conventional manner by adjustable web straps 22.
