JPS6017131Y2 - Hanging ring mounting bracket for school bags that can move up and down - Google Patents

Description

[Detailed Description of the Invention] This invention relates to a vertically movable hanging ring mounting bracket for a school bag, which can only move up and down in a regular manner on a track to prevent the hanging ring from falling down.

Up to now, the vertically movable hanging ring was housed and held by bending a plate-shaped piece connected to the main body of the band mounting bracket in the center, and the upper side of the bend was attached to the locking part of the hanging ring. On the other hand, the latching ring was capable of being latched to the latching portion, and had separate openings on both sides below the overlapping leg portion.

The retaining ring is rotatable at the retaining portion, and if the retaining ring remains rotated and lies down, there is a drawback that it may cause a collision accident on the nape of the neck of the person carrying the backpack.

The object of this invention is to provide a vertically movable hanging ring attachment for a school bag, which solves the conventional drawbacks and allows regular vertical movement.

An example of this invention will be described with reference to the drawings.
FIG. 1 is a rear view of the metal fitting of the present invention, FIG. 2 is a central vertical cross-sectional view of the device in use, and FIG. 3 is a cross-sectional view thereof.

In this invention, a supporting member 2 having a vertical groove is installed vertically on the band mounting bracket mounting bracket main body 1 to form a sliding part 8 of the hanging ring, and the support member 2 is installed inside this sliding part 8 and can move freely up and down. The leg portion of the hanging ring 3 is a bifurcated leg 4 with a spaced interval that is slightly narrower than the width of the sliding portion 8 and whose lower end is connected. A vertically movable latching ring mounting bracket for a school bag that has a latching means 5 provided at an appropriate position on the sliding portion 8 is recommended.

The band mounting bracket body 1 is made by folding the plate surface into a shape with a notch in the center so that the center does not overlap, and the connecting ring 6 of the shoulder strap is held on one side of the plate so that it can rotate freely. A sliding portion 8 of the leg portion of the retaining ring 3 is formed by forming a cylindrical portion 7 that can be held in place, and fixing a supporting member 2 having a vertical groove to the other surface.

The legs of the hanging ring 3 stored in the sliding part 8 have a length such that the lower end thereof in the stored state emerges from the lower side of the band mounting bracket main body 1, and the head part is bent outward when hanging the school bag. Eliminates band failure.

Although the drawer is long enough, the cushioning material on the back plate is pressed during storage, so the lower part of the latch ring is pressed against it to prevent it from rolling out.

The leg part has a hook part 9 that connects the lower part of the bifurcated legs 4 with an interval between them, and between the bifurcated legs 4 there is a shaft of a rivet 11 that can fix the band attachment fitting main body 1 to the school bag back plate 10. 12 is interposed at the intermediate position and controls the upward extension length of the retaining ring.

In addition, the drawing code 13 is a cushion material, 14 is a core plate, and 15
is the skin material, 16 is the interior material, 17 is the outer skin of the mounting bracket,
It is sewn and fixed to the skin material 15.

The above is the configuration of this invention, and its operation and effect will be explained by comparing it with the conventional one shown in FIGS. 4 and 5. Since it is regulated by a wall and the inside is regulated by a shaft 12 riveted in the center, there is no left and right wobbling, and vertical movement is extremely smooth.

When the school bag is latched, the upper part of the leg of the latching ring comes out from the mounting bracket body 1, but the lower part contacts the inside of the mounting bracket body 1 and the support member 2, so that rotational movement in the front and back direction is controlled.
There is no possibility of it lying down, and since it can come into contact with the side wall of the sliding part 8, the rotational movement in the left and right directions is also controlled, so it will not remain in a state of being rotated to the right or left.

Therefore, even if you forget to put the latching ring back in when you remove the schoolbag from its latches and put it on your back, the latching ring will not rotate, so it will not hit the user's neck and cause injury. Since it can only move up and down in one direction, the retaining ring will automatically descend.

That is, since the left and right and front and rear directions are restricted, the connecting ring 6 can only move up and down.

Next time when you carry it on your back, the hanging ring will be lowered and stored in the mounting bracket, but
The lower part of the leg presses the cushioning material 13 and descends, and the cushioning material springs and fixes as if crimped to the inner surface of the mounting bracket body, so that even if the school bag swings, the latching ring will not close to the mounting bracket body 1. It won't jump out.

On the other hand, in the conventional type, the locking action of the locking ring 3' is performed at the upper side of the mounting bracket main body 1', and this portion is rotatable.

Therefore, when the school bag is latched, the band may be obstructed and the bag may be easily latched.

However, since there are no restrictions on both sides and the center of the leg as in the present invention, when it is stored in the mounting bracket, a load is applied to the latching ring due to forced storage, such as lowering the leg while tilting to either the left or right. Damage such as falling off from the mounting bracket main body 1' can be avoided, and it may also lead to an unexpected accident such as the blade flying out from the mounting bracket and falling over when the backpack is carried on the back.

However, according to this invention, there is no possibility of such damage or accidents.

As described above, the present invention is extremely sturdy considering that the latching metal fittings are frequently used, and is capable of accurate lifting and lowering operations, and is capable of being used in any situation when lying down. The fact that this was completely prevented in this case is an epoch-making invention that made it possible to provide an extremely safe school bag since the intended users of the school bag were children.
