BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a backpack bag such as a backpack.

[0002]

2. Description of the Related Art Conventionally, the mounting position of the upper end portion of the backpack belt can be vertically displaced so that anyone can easily carry it, regardless of the difference in height of the person carrying it on the back. There is a backpack bag. 7 and 8 show an example of such a backpack bag. Hereinafter, this conventional example will be described. In this backpack bag, a shoulder belt attachment plate 2 called a "patch" made of plastic for connecting the upper ends of the shoulder belts 1a and 1b is provided separately from the bag body 3, while the back surface of the bag body 3 is provided. 4 is provided with tape-shaped hooks 9 which are parallel to each other in a lateral arrangement and whose inner surface portions are opened in the vertical direction at a plurality of positions where the height of the central portion is different,
A hook-and-loop fastener (trade name is "Velcro" or "velcro tape") that can be inserted into the hooks 9 and is provided in the lower half of the hooks 9.
Etc.), and a mounting belt 6 provided with a hook portion 5b of a planar fastener in the upper half thereof, respectively. The mounting belt 6 is attached to the lower end portion of the shoulder belt mounting plate 2 described above. The shoulder belt mounting plate 2 is attached to the backrest surface 4 of the bag main body 3 at an arbitrary height by connecting the shoulder belt mounting plate 2 to the mounting hole 7 provided and then folding back to lock the receiving portion 5a and the hanging portion 5b of the planar fastener. It can be installed in any position.

However, in the conventional backpack bag as described above, the adhesion of the shoulder belt mounting plate 2 to the backrest surface 4 of the bag body 3 is poor and unstable, so that when the bag body 3 is carried on the back, the bag body is walked. 3 swayed from side to side, making it difficult to walk and tired easily. Further, since the load of the bag body 3 is mainly supported by the locking force of the receiving portions 5a and the hanging portions 5b of the sheet-like fasteners in the mounting belt 6, the receiving portions 5a and the hanging portions 5b are easily fatigued and deteriorated so that they are durable. There was also the problem of inferiority.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above problems, that is, improves the adhesion between the shoulder belt attachment plate and the backrest surface of the bag body in the backpack bag to make the bag body less prone to shake. At the same time, the purpose of the present invention is to reduce the load applied to the surface fastener of the mounting belt, prevent deterioration, and improve durability.

[0005]

In order to achieve the above object, the backpack bag according to the present invention is provided with a shoulder belt attachment plate 2 for connecting the upper ends of the shoulder belts 1a and 1b separately from the bag body 3. In a backpack bag in which the shoulder belt mounting plate 2 can be fixed at an arbitrary position on the backrest surface 4 by connecting the mounting belt 6 fixed to the backrest surface 4 of the bag body 3 to the shoulderrest belt mounting plate 2. , Providing projecting pieces 10 and 11 on the upper and lower ends of the shoulder belt mounting plate 2, respectively,
The projecting pieces 10 and 11 of the above-mentioned shoulder belt mounting plate 2 are formed inside the bag body 3 by opening the inner surface portion in parallel to each other at a plurality of different heights on the backrest surface 4 in a lateral arrangement and in the vertical direction. The tape-shaped hook 9 is provided which can be inserted from the vertical direction so as to be pinched.

[0006]

The projecting pieces 10 and 11 provided on the upper and lower ends of the shoulder belt mounting plate 2 are inserted into the inner surface portions of the hooks 9 provided at a plurality of positions on the backrest surface 4 of the bag body 3 at different heights so as to be caught. By doing so, the shoulder belt mounting plate 2 comes into close contact with the backrest surface 4 and the fixation is stabilized.

Further, the load of the bag body 3 is the mounting belt 6
Since the projecting piece 10 provided on the upper end of the shoulder belt mounting plate 2 is also borne by the hook 9 which is inserted into the inner surface portion, the burden on the planar fastener of the mounting belt 6 is reduced. Reduce.

[0008]

Embodiments of the present invention shown in the drawings will be described below. First, FIGS. 1 to 3 show a first embodiment. In the figure, reference numeral 2 is a plastic shoulder strap mounting plate called a "patch", and upper ends of a pair of left and right shoulder straps 1a and 1b are connected to both shoulder portions of the shoulder strap mounting plate 2. The shoulder belt attachment plate 2 is separated from the bag body 3 and can be moved to any position on the backrest surface 4 of the bag body 3. The shoulder belt mounting plate 2 is provided with projecting pieces 10 and 11 at both upper and lower ends, and two laterally long mounting holes 7 and 8 are formed in the lower projecting piece 11 so as to be parallel and close to each other in a vertical arrangement. I have set up.

Sideways tape-shaped hooks 9 are provided at equal intervals at a plurality of positions at different heights in the central portion of the backrest surface 4 of the bag body 3. The hooks 9 are parallel and arranged vertically, and both ends thereof are sewn to the back contact surface 4 to open the intermediate inner surface portion in the vertical direction.

A mounting belt 6 is also provided at the center of the back surface 4 of the bag body 3. The lower end of the attachment belt 6 is fixed to the backrest surface 4, and the portion above it is free. In addition, a receiving portion 5a of a planar fastener in which a large number of loop-shaped yarns are planted is provided in a substantially lower half portion of the attachment belt 6, and a large number of hook-shaped yarns are also implanted in a substantially upper half portion of the above. The hook portion 5b of the planar fastener that can be locked to the receiving portion 5a is provided. The attachment belt 6 is inserted through the inner surface of each hook 9 described above.

The shoulder belt mounting plate 2 is fixed to the backrest surface of the bag body 3 by the following procedure. First, shoulder belt mounting plate 2
Is arranged at a position at an arbitrary height in the center of the backrest surface 4, and the attachment belt 6 is connected to the shoulder belt attachment plate 2. In this case, of the two mounting holes 7 and 8 provided in the shoulder belt mounting plate 2, first, the mounting belt 6 is inserted into the upper mounting hole 7 from the back side, and then the mounting belt 6 protruding to the front side is inserted. This time, conversely, the lower mounting hole 8 is inserted from the front surface side to the rear surface side, and then the tip of the mounting belt 6 is inserted downward to the inner surface portion of the hook 9 to receive the planar fastener. 5a and hook 5b are locked. In this way, when the mounting belt 6 is inserted into the two mounting holes 7 and 8 of the shoulder belt mounting plate 2, the two mounting holes 7 and 8 are the same as the belt length adjuster generally called "koki". The mounting belt 6 is firmly fixed by exerting a stopper function. As in the above-mentioned conventional example, since there is no stopper function if there is only one mounting hole, the load of the bag body against the locking force of the sheet fastener is large, but two mounting holes are used as in this embodiment. If the holes 7 and 8 are provided so as to have a stopper function, the load is applied to the main body of the mounting belt 6 and the shoulder belt mounting plate 2, so that the load on the planar fastener becomes extremely small. Next, the protruding piece 1 provided on the upper end of the shoulder belt mounting plate 2
0 is inserted into the inner surface portion of the hook 9 located above it from below, and the protruding piece 11 provided at the lower end of the shoulder strap mounting plate 2 is inserted into the inner surface portion of the hook 9 located below it from above. As a result, the upper and lower ends of the shoulder belt mounting plate 2 are pressed down, do not float, and come into close contact with the backrest surface 4, and there is no vertical displacement. Further, since a part of the load applied to the shoulder-belt mounting plate 2 as described above also acts on the hook 9 into which the protruding piece 10 provided at the upper end of the shoulder-belt mounting plate 2 is inserted, The burdens on the belt 6 and the receiving portions 5a and the hanging portions 5b of the planar fasteners of the mounting belt 6 are reduced.

Next, FIGS. 4 to 6 show a second embodiment of the present invention. In the above-described first embodiment, the number of the projecting pieces 10 and 11 provided at the upper and lower ends of the shoulder belt attachment plate 2 is only one, but in the second embodiment, the upper portion of the shoulder belt attachment plate 2 is at the upper end. Protruding pieces 10 and 11 are provided at two places on the left and right and two places on the left and right at the lower end, respectively. In response to this, the hooks 9 provided on the backrest surface 4 of the bag body 3 are made a little longer, and both ends and the central portion are sewn to the backrest surface 4 so that the protrusions 10 on the left and right sides are separated. Each of 11 can be inserted into the inner surface portion. Further, the attachment belt 6 is also provided with two right and left and is inserted into the inner surface portion of the hook 9, respectively. The other structure is the same as that of the first embodiment. If the two protruding pieces 10 and 11 are provided on the upper and lower ends of the shoulder-belt mounting plate 2 as in the second embodiment, the four corners of the shoulder-belt mounting plate 2 are held down. As compared with the case where the projecting pieces 10 and 11 are one as in the first embodiment, the fixing of the shoulder belt mounting plate 2 by the hook 9 is more stable. Further, lateral displacement of the shoulder belt mounting plate 2 can be suppressed.

[0013]

The present invention is as described above, and since the adhesion of the shoulder belt mounting plate 2 to the back-contacting surface 4 of the bag body 3 is improved and the fixed state is stabilized, when the bag body 3 is carried on the back. The effect is that it can suppress the swaying of the body and make it easier for the person carrying the back to walk and less tired. Further, since a part of the load of the bag body 3 is shared by the hooks 9, there is an effect that the load on the surface fastener of the mounting belt 6 is reduced, deterioration is suppressed, and durability is improved. If the shoulder belt mounting plate 2 is provided with the two mounting holes 7 and 8 as in the above-mentioned embodiment and the stopper function is provided like "Koki", the load of the sheet fasteners becomes extremely small. Is big.
