Description

[Detailed description of the invention] Conventionally, buttons that are attached to relatively stiff fabrics such as jeans are firmly attached with metal rivets, so the buttons do not move and it is extremely difficult to remove them from the button holes. Ta.

In addition, the button whose button head rotates in a flat position is made in Jitsukō 39-2821.
The button is an enlarged portion at the base of the fixed tube, and is configured to enclose a tightening plate having an insertion hole with a slightly smaller diameter than the stop pin with a cut in order to fix the stop pin. The fixing mechanism to the fabric requires a tightening plate having an insertion hole with a cut, a retaining piece, and a stop pin in addition to the process of wrapping the plate in the bulk part, and the stop pin is drilled in the center of the tightening plate. The locking pin is inserted into an insertion hole with a smaller diameter than the locking pin, and the notches provided radially around the hole are used to engage the locking pin, so if the button head is pulled strongly, the locking pin will force the locking pin to tighten as many of the notches act elastically. There is a risk of loosening, the structure is complicated, the number of assembled parts is large, and manufacturing is expensive.

The present invention improves these drawbacks and makes it possible to manufacture and provide a durable button that is easy to put on and take off at a low cost.

To explain the embodiment of the present invention, the middle plate 1
The outer peripheral edge of 1 is formed into a flat part 17, and the middle seat plate 11
A hard metal backing plate 8 is placed on a seat part 7 having an engagement chamber 6 having a floating hole 5 with a folded part 19 formed around the center, and a connecting pipe 12 protruding from the center thereof. 9 is loosely fitted into the floating hole 5 of the button head 10 on which the connecting tube 12 is fitted, and the distal end of the connecting pipe 12 is curved to a wider diameter than the outer peripheral wall of the floating hole 5 to form a wide distal end peripheral edge 13. Insert the hollow leg 2 of the
The distal end thereof is enlarged and deformed into a substantially mushroom shape and fixed to the distal end periphery 13 of the connecting pipe 12, and is not fixed to the above-mentioned backing plate 8.

When attaching the button of the present invention to fabric such as jeans or clothing, place the fabric 14 on the middle seat plate 11 shown in FIG.
The hollow leg 2 of the attachment part 4 is placed along the connecting pipe 12 at the center of the middle seat plate, and the top plate 3 of the attachment part 4 is strongly pressed from above.

Since the tip of the hollow leg 2 is a sharp point, the attachment part 4 breaks through the fabric 14 and penetrates the inside of the connecting tube 12, and the tip of the hollow leg 2 comes into contact with the hard metal contact plate 8. The material 14 expands and deforms into a substantially mushroom shape and adheres to the peripheral edge 13 of the distal end of the connecting tube 12, so that the hollow leg 2 and the connecting tube 12 are integrally fixed, and the fabric 14 is attached to the seat plate 1 and the middle seat plate 11.
It is reliably and firmly clamped with a space 18 between the two.

In the present invention, as shown in FIGS. 2 and 3, the inner diameter of the floating hole 5 of the seat plate 7 of the button head 10 is formed to be slightly larger than the diameter of the hollow connecting tube 12, so that the connecting tube 12 is loosely inserted. The distal end of the connecting pipe 12 is fixed to the distal end periphery 13 which is curved to have a larger diameter than the peripheral wall of the floating hole 5 by enlarging and deforming the distal end portion of the hollow leg 2 of the attachment portion 4 into a substantially mushroom shape. Abutting plate 8 whose roughly mushroom-shaped part has a button head 10
Therefore, when attached to the fabric 14, the button head 10 can rotate around the connecting tube 12 and tilt forward, backward, left and right.

Therefore, the button head 10 can be easily inserted into and removed from the button hole 16 of the other fabric 15.

Note that the peripheral edge 13 of the leading end of the connecting pipe 12 of the middle seat plate 11
In this case, the inclined wall on the back surface of the enlarged and deformed part of the tip of the hollow leg 2 of the attachment part 4 is formed by overlapping, so that the button of the present invention is extremely strong against forceful pulling of the button head 10.
The hollow legs 2 are not loosened or damaged.

Furthermore, the button head 10 can be easily attached to the fabric 14 by pressing the top plate 3 of the attaching part 4.
Since the attachment part 4 can be attached to the button 2, attaching the button is extremely easy.

In addition, since the outer peripheral edge of the middle seat board 11 is formed flat, the fabric 14 is held between the seat board 1 and the flat part 17 on the outer periphery of the middle seat board 11 via the space 18. The mounting fabric 14 is securely and firmly clamped without wrinkles.

Moreover, the button of the present invention has a folded part 19 around the floating hole 5.
, the connecting pipe 12 of the middle seat plate 11 can be easily tilted back and forth and left and right, so the button head 10 can be easily tilted.
can be fitted and removed.

As described above, the button of the present invention is durable, has a relatively small number of parts, and has a relatively simple structure, making it easy and simple to manufacture.

Therefore, since it can be mass-produced, it has the advantage of being able to provide durable products at low cost.
