Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a backpack used for mountain climbing and the like.

[0002]

2. Description of the Related Art The length of a belt such as a shoulder belt attached to a backpack depends on the size of the backpack. However, the belt may be too long or too short depending on the physique of the person carrying the Zach, the type of clothes worn, the number of clothes, and the like. For example, it is often too short when a man with a large physique is heavily dressed in winter, and too long when a small woman is lightly dressed in summer. Therefore, it is necessary to adjust the length of the belt, and in the conventional Zac, a single length adjustment tape with a fixed length attached to the handjob etc. is connected to the shoulder belt,
The length of the length adjustment tape is adjusted. However, there is a dissatisfaction that it is difficult to adjust the belt to an optimum length because the adjustment range is narrow only by changing the length of one length adjustment tape.

[0003]

SUMMARY OF THE INVENTION Therefore, according to the present invention, the range in which the length of the belt attached to the backpack body can be adjusted can be expanded, and the belt can be adjusted to an optimum length according to the size of the person carrying the backpack. The task is to provide a Zach that can do it.

[0004]

In order to solve the above-mentioned problems, a zac according to the present invention comprises two length adjusting tapes 4 and 5 as components of a belt, and one of the length adjusting tapes 4 is attached to one of the length adjusting tapes 4. The length adjuster 6 is configured by attaching the handjob 7 movably in the longitudinal direction thereof and integrally attaching the lock body 9 capable of fixing the handjob 7 to the length adjusting tape 4 to the handjob 7, The lock body 9 of the length adjusting tool 6 is attached to the other length adjusting tape 5 so as to be movable in the longitudinal direction and fixed at an arbitrary position. It is.

[0005]

Embodiments of the present invention will be described below with reference to the drawings. First, FIG. 1 shows a backpack in which the length of the shoulder belt 2 can be adjusted.
Two shoulder belts 2 are attached to the front surface of the Zach main body 1. This shoulder belt 2 has a shoulder pad 3 whose upper end is fixed to the Zach main body 1 and whose lower end is free, and a lower end of the shoulder pad 3. An upper length adjusting tape 4 having an upper end connected to a lower portion and a lower end being free, a lower length adjusting tape 5 having a lower end fixed to the backpack 1 and an upper end being free, and a lower length adjusting tape 4 having an upper end being free. And a length adjusting tool 6 for connecting the unit length adjusting tape 5.

The length adjuster 6 is composed of a footjob 7 and a lock body 9 which is rotatably fixed at one end to the footjob 7 by a shaft 8 and integrally attached thereto.

The footjob 7 is provided with a plurality of through holes 10 that open from the front side to the back side, and the upper length adjusting tape 4 is inserted into these through holes 10 while bending. The footjob 7 is movable in the longitudinal direction of the upper length adjusting tape 4.

The lock body 9 also has a plurality of through holes 11 that open from the front side to the back side, and the lower length adjusting tape 5 is inserted through these through holes 11 while bending. The lock body 9 is movable in the longitudinal direction of the lower length adjusting tape 5 and can be fixed at an arbitrary position.

The lock body 9 can be raised and lowered with respect to the footjob 7 so that the lock body 9 presses the upper length adjusting tape 4 against the footjob 7 when the lock body 9 is turned down as shown in FIG. By tightening, the footjob 7 can be fixed to the upper length adjusting tape 4 and locked so as not to move.

When the lock body 9 is raised as shown in FIG. 4, the lock body 9 loosens the tightening of the upper length adjustment tape 4 to release the locked state, so that the upper length adjustment tape 4 is released. Is movable.

That is, the length of the shoulder belt 2 can be adjusted by moving the lock body 9 of the length adjusting tool 6 with respect to the lower length adjusting tape 5. Footjob for length adjuster 6
The length of the tape can also be adjusted by moving the length adjustment tapes, and the length of both length adjustment tapes 4 and 5 can be adjusted, so that the adjustment range can be expanded.

In addition to the above-mentioned shoulder belt 2, the Zach main body 1 can be provided with a squeezing prevention belt 12 called a top pull that pulls the upper part of the Zach main body 1 forward. FIG. 6 shows a backpack in which the length of the squeezing prevention belt 12 can be adjusted. An upper length adjusting tape 4 whose upper end is connected to the upper part of the Zach main body 1 and whose lower end is free,
It comprises a lower length adjusting tape 5 whose lower end is connected to the shoulder belt 2 and whose upper end is free, and a length adjusting tool 6 for connecting the lower length adjusting tape 5 to the upper length adjusting tape 4. The length adjuster 6 is also constructed by integrally assembling the footjob 7 and the lock body 9 and has the same function as that attached to the shoulder belt 2 described above.

Conventionally, the upper length adjusting belt 4 and the lower length adjusting belt 5 which can be connected to the upper length adjusting belt 4 constitute a twist prevention belt 12, and the upper length adjusting belt 4 and the lower length adjusting belt 5 are connected. There is a Zach whose length can be adjusted, but it has a structure in which a footjob 7 is attached to an upper length adjustment belt 4 and a lower length adjustment belt 5, respectively. I have. In contrast,
In the backpack according to the present invention, since the foot adjuster 6 and the lock body 9 are integrally assembled to form the length adjuster 6, each of the upper length adjuster belt 4 and the lower length adjuster belt 5 of the creel prevention belt 12 is provided. There is an advantage that the length can be adjusted with only one length adjuster 6.

[0014]

The backpack according to the present invention is as described above, and the lengths of the two length adjusting tapes 4 and 5 are respectively adjusted by one length adjusting tool 6 composed of the footjob 7 and the lock body 9. As a result, the range in which the length can be adjusted is increased as compared with the conventional case, and the belt can be adjusted to an optimal length according to the physique of the person carrying the bag.
