Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a flexible fastener that is attached to bags such as school bags and bags, and other items, and that connects the hooks at the ends of belts, straps, and the like.

(Prior art) Such a flexible fastener is designed in Design Registration No. 305180 and No. 305180.
It is known from the publication No. 332550.

(Problem that the invention aims to solve) Each part of the conventional fastener is made of metal, and the ring part that hooks and connects the hook of the belt or strap has a C
It is molded into a shape, and its ends are inserted into the holes on both sides of the central cylindrical part that can rotate 360 degrees. For this reason, when a strong tensile force is applied from the belt or strap, the C-shaped ring expands and breaks through the holes on both sides of the central tube, causing damage. In addition, screws and rivets protrude from the back of the base plate that rotatably supports the central tube for attachment to bags, etc., and when attached, the nuts and rivet caulking portions are exposed on the back of the bag, resulting in an unsightly appearance.

(Means for Solving the Problems) Therefore, the present invention has an endless ring and a flange extending from the outer periphery at the lower end, and in order to hang the ring so that it can be raised and lowered, the ring is cut halfway upward from the lower end including the flange. It has a shaft with a deep cut groove, a thin peripheral part, a recess in the center that is open to the lower surface and rotatably accommodates the collar of the shaft, and the upper wall of the recess has a It is characterized by comprising a hole through which the shaft is rotatably passed, and a mounting plate provided with a slit communicating with the hole for deforming and passing the ring across the hole.

(Example) In the drawings, 1 is an endless ring, 2 is a shaft, 3
indicates a mounting plate, and in this embodiment, the three parts mentioned above are made of plastic, but the ring may be made of metal, with the joints at both ends brought into close contact.

Note that the ring is not limited to the D shape shown in the drawings, but may be any shape such as O, circular, oval, triangular, or quadrangular.
The shaft 2 has a flange 4 projecting from the outer periphery at the lower end, and a cut groove 5 cut halfway upward from the lower end including the flange 4 so that the endless ring 1 can be hung up and down. The width of this cut groove 5 is, of course, slightly larger than the thickness of the ring 1.

The mounting plate 3 has a thin peripheral part 6, and the central part has a recess 7 open to the lower surface for rotatably housing the collar 4, and a raised upper wall 7' of the recess 7 has a shaft 2. A rotatably passing hole 8 and diametrically opposed slits 9, 9 communicating with said hole are provided. To assemble these three parts, first, as shown in FIG. , 9 from below along with shaft 2. As a result, the ring 1 is slightly deformed and the slits 9, 9
The shaft 2 also projects upward from the hole 8 from the portion where the ring crosses, and the collar 4 is rotatably housed inside the recess 7.
Note that the depth of the recess 7 is made slightly larger than the thickness of the collar 4.

After the ring 1 passes through the slits 9, 9,
Since it will be restored on the upper wall of the recess, temporarily slit 9,
Even if it is aligned with 9, it will not fall down, so the above three parts are maintained in the assembled state. The shaft 2 can rotate 360 degrees with respect to the mounting plate together with the ring 1, and since the ring 1 can be raised and lowered with respect to the shaft 2, a band or strap 1 connected to the ring 1 with a hook 10 can be attached.
1 can freely face the direction in which it is pulled.

Thin peripheral part 6 for attaching to fabrics such as bags
All you have to do is pass the thread 12 through with a needle and sew. Incidentally, in order to reinforce the thin peripheral portion, it is preferable to provide a thickened portion 13 integrally along the outer edge thereof.

The mounting plate 3 is not limited to a circular shape as shown in the drawings, but may be square or any other arbitrary shape. By molding each part 1, 2, 3 or 2, 3 out of plastic, it can be colored in a color that harmonizes with the color of the object to which it is attached, such as a bag.

(Effect of the invention) Since the ring 1 of the flexible fastener of the present invention is endless, if a strong tensile force is applied from the strap 11, the connection between the ring and the shaft will come undone unless ring 1 is torn or the upper part of the shaft is torn. do not have. Since the mounting plate is stacked on top of the fabric such as a bag and sewn to the fabric using thread at the thin peripheral part, screws, nuts, and caulked parts of rivets do not protrude from the back side of the fabric, resulting in a good appearance.

[Brief explanation of the drawing]

The drawings show one embodiment of the present invention; Fig. 1 is a perspective view of the device attached to fabric, Fig. 2 is a perspective view of the disassembled parts, and Fig. 3 is a perspective view of the assembled ring and shaft. Figures 4 and 4 are front views of half of the state shown in Figure 1, in which 1 is a ring, 2 is a shaft, and 3 is a cross-sectional view.
4 is a mounting plate, 4 is a flange, 5 is a cut groove, 6 is a thin peripheral part, 7 is a recess, 7' is an upper wall of the recess, 8 is a hole, and 9 is a slit.

Claims (1)

[Scope of utility model registration request] an endless ring, a shaft having a flange extending from the outer periphery at the lower end, a cut groove cut halfway upward from the lower end including the flange in order to allow the ring to hang up and down, and a thin periphery. The center part has a recess open to the lower surface for rotatably accommodating the collar of the shaft, and the upper wall of the recess has a hole through which the shaft rotatably passes; and a mounting plate provided with a slit communicating with the hole for deforming and passing the ring therethrough.
