Description

[Detailed Description of the Invention] [Industrial field of application] This invention is a shoulder belt having a dharma seat for attaching a shoulder belt or the like of a school bag, particularly a bra part of the school bag detachably attached to the main body of the school bag, and a dharma can. Related to the provision of fixtures such as.

[Prior Art] Usually, the shoulder belt of the school bag is locked so that the length of the shoulder belt of the school bag body can be adjusted with respect to the bra portion fixed to a fitting called "Darmacan" of the Dharma seat provided on the bottom surface of the body. ing.

In the school bag shown in FIG. 21, the bra part n is fixed by using the dalma can m assembled to the conventional dharma seat, and the lower part of the shoulder belt body p is attached to the buckle u of the bra part n. It is inserted and locked, and the length of the shoulder belt body p can be adjusted.

[Problems to be solved by the invention] With such a conventional school bag, it is possible to adjust the length of the shoulder belt, and by fitting the shoulder belt to the height of the user of the school bag, it is easy to put on and take off the school bag and carry it on the back. The backpack was properly attached to the back so that the backpack was easy to carry.

Further, by releasing the engagement between the shoulder belt main body p and the bra portion n, the curved state formed by the shoulder belt main body p and the bra portion n is eliminated, so that the shoulder belt main body p and the like are provided on the back side of the school bag. It could be turned around to package, or it could be folded and packaged, and the structure was convenient for storing and delivering school bags.

Further, in the case where the shoulder belt of the school bag on the back is held in a tensioned state and the upper arm cannot be pulled out from the shoulder belt, the bra portion n
Therefore, by unlocking the shoulder belt main body p, there is an advantage that the school bag can be detached without removing the upper arm from the shoulder belt.

However, because the bra portion n locked to the shoulder belt body p is fixed to the school bag body,
This bra portion may come into contact with the skin surface or the like of the school bag when the school bag is packaged, which may damage the decorative surface of the school bag, and it is difficult to avoid the bulkiness of the package.

Further, when the shoulder belt of the school bag which is carried on the shoulder bites into the shoulder portion and the locked state between the shoulder belt body p and the bra portion n cannot be released, either the shoulder belt body p or the bra portion n is I had to disconnect and release.

Furthermore, even if the bra part is damaged or dirty,
Since only the bra part cannot be replaced, the school bag itself cannot be used.

Furthermore, since the attached bra part cannot be used by replacing it with another bra part having a different length, it cannot be diverted to a person whose height is extremely different, and there is a limit to the transfer and reuse of the school bag. It was

The mounting device according to the present invention is made so that the bra part can be freely removed from the satchel body by devising the above-mentioned daruma seat and darumakan provided on the satchel etc. Provided with a fixture that allows the shoulder belt of the car to be released without pulling out the shoulder, replaces a damaged or soiled bra part, and freely changes it to a part having a different length. It is an object.

[Means for Solving the Problems] In order to achieve the above object, the fixture according to the present invention has a structure such as a shoulder belt, in which a mounting base A having a cylindrical boss portion, A buckle B having a cylindrical bearing portion 2 rotatably fitted to the boss portion 1 and a boss portion 1 of a mounting base A to which the bearing portion 2 of the buckle B is fitted. It is composed of a shaft-rod-shaped lock pin C that is inserted in a removable manner and is twistable.

On one side of the lock pin C, a collar-shaped head 3 that engages with the bearing portion 2 of the buckle B is provided, and on the side opposite to the head 3 of the lock pin C. The rod 4 in a direction substantially orthogonal to the rod 4 of the lock pin C.
There is provided a lock portion 5 protruding from the side to the side.

Further, the mounting base A into which the lock pin C is inserted
The boss portion 1 is provided with a long hole 6 in one direction through which the lock portion 5 of the lock pin C is inserted, and the boss portion 1 on the side through which the lock portion 5 is inserted is provided. A space 7 for accommodating at least the lock portion 5 of the lock pin C is provided on the short width side of the hole 6.

The head 3 of the lock pin C, which is inserted and twisted into the boss 1 of the mounting base A on which the bearing 2 of the buckle B is fitted, engages with the bearing 2 in the state described above. The lock portion 5 of the lock pin C passing through the hole 6 is configured to engage with the surface 7a of the space 7 along the short width side of the hole 6.

[Operation] Buckle B that constitutes a fixture such as a shoulder belt
The bearing portion 2 is fitted to the boss portion 1 of the mounting base A, and the head portion 3 of the lock pin C inserted and twisted in the boss portion 1 is engaged with the bearing portion 2, and Since the lock portion 5 of the lock pin C inserted into the hole 6 of the boss portion 1 is configured to engage with the surface 7a as the screw is twisted, the lock portion 5 is rotatable with respect to the boss portion 1 of the mounting base A. Has been done.

Further, by twisting the lock pin C, the lock portion 5 of the lock pin C is turned from the surface 7a of the space 7 to the hole 6 side, and the length direction of the lock portion 5 is aligned with the length direction of the hole 6. Since the lock portion 5 of the lock pin C is unlocked, the lock pin C can be removed and the buckle B can be detached.
