Abstract

(57) [Summary] [PROBLEMS] To provide an eyelet metal fitting in which a female die passed through a male cylindrical portion is hard to fall off. SOLUTION: The eyelet fitting includes a male die 1 and a female die 2.
The male die 1 has a cylindrical portion 1a and a collar portion 1b provided on the lower edge of the cylindrical portion 1a. Further, the female die 2 is an annular one that is passed through the cylindrical portion 1 a of the male die 1. Male 1
The upper edge of the cylindrical portion 1a is flared outward in a bosh-like shape. The diameter d of the upper edge is substantially equal to the inner diameter D of the female die 2, and the upper edge substantially contacts the inner circumference of the female die 2. Once the female die 2 is passed through the cylindrical portion 1a of the male die 1, the female die 2 is caught on the upper edge of the cylindrical portion 1a of the male die 1, so that the female die 2 does not easily fall off from the cylindrical portion 1a.

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to eyelet fittings for reinforcing a hole in a fabric through which a cord is passed, for example.

[0002]

[Prior art]

 This type of eyelet fitting is composed of a male die 41 and a female die 42 as shown in FIG. 4, and is formed by punching out a thin metal plate. The male die 41 has a cylindrical portion 41a and an annular flange portion 41b provided on one of both edges of the cylindrical portion 41a.

As shown in FIG. 5, the cylindrical portion 41a of the male die 41 is passed through the hole 43a of the cloth 43, and then the annular female die 42 is passed through the cylindrical portion 41a, and the cylindrical portion 41a is crushed and expanded. When peeled, the eyelet fitting rims the hole 43a of the fabric 43 and reinforces the hole 43a.

[0004]

[Problems to be solved by the device]

 By the way, when attaching a plurality of eyelet fittings, the work procedure is as follows. First, the cylindrical portions 41a of all the male dies 41 are passed through the holes of the fabric and the female dies 42, and then the cylindrical portions of the male dies 41 are inserted. 41a is squeezed in sequence and expanded.

However, even if the female die 42 is passed through the cylindrical portion 41a of the male die 41, the female die 42 is easily removed from the cylindrical portion 41a, and the male die 41 is not noticed that the female die 42 has come off. Often, the cylindrical portion 41a was crushed. In this case, the crushed male mold 42 is removed from the cloth, and after that, the work of attaching a new eyelet metal fitting is to be redone, but this is often the case, and it took a lot of time and effort.

Therefore, an object of the present invention is to provide an eyelet fitting in which a female die passed through a male cylindrical portion is hard to drop off.

[0007]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a male mold including a cylindrical portion and a flange portion provided at one of both edges of the cylindrical portion, and the male cylindrical portion through the male cylindrical portion. In the eyelet metal fitting including an annular female die facing the part, the other edge of the male cylindrical portion is expanded outward until the other edge substantially contacts the inner periphery of the female annular shape.

According to this invention, the other of the both edges of the male cylindrical portion is expanded outward until it substantially contacts the inner circumference of the female annular portion. Therefore, once the female mold is passed through the male cylinder, the female mold is caught on the edge of the male cylinder and is difficult to separate from the male mold.

Further, instead of expanding the edge of the male cylindrical portion to the outside, a part of the male cylindrical portion is projected outward until a portion of the male cylindrical portion substantially contacts the inner circumference of the female annular portion. Does not matter.

Also in this case, once the female die is passed through the male cylindrical portion, the female die is caught on a part of the cylindrical portion and is unlikely to come off the male die.

[0011]

[Embodiment of device]

 Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows an embodiment of an eyelet fitting of the present invention. This eyelet fitting is composed of a male die 1 and a female die 2. The male die 1 has a cylindrical portion 1a and a collar portion 1b provided on the lower edge of the cylindrical portion 1a. Further, the female die 2 is an annular one that is passed through the cylindrical portion 1 a of the male die 1.

The upper edge of the cylindrical portion 1 a of the male die 1 is flared outward in a boshish shape. The diameter d of the upper edge is substantially equal to the inner diameter D of the female die 2, and the upper edge is substantially in contact with the inner circumference of the female die 2.

Once the female die 2 having such a shape is passed through the cylindrical portion 1a of the male die 1, the female die 2 is caught on the upper edge of the cylindrical portion 1a of the male die 1 and is easily removed from the cylindrical portion 1a. Will never fall out. For this reason, it is possible to reduce the operational error of crushing the cylindrical portion 1a of the male die 1 without noticing that the female die 2 has fallen off as described above, and improve the working efficiency. Can be expected.

FIG. 2 shows another embodiment of the eyelet fitting of the present invention. Here, a plurality of convex portions 4 are formed on the cylindrical portion 3a of the male die 3, and the diameter d 1 of the circle in contact with these convex portions 4 is set to be substantially equal to the inner diameter D of the female die 5.

In the case of this eyelet fitting, when the female die 5 is passed through the cylindrical portion 3a of the male die 3, the female die 5 is caught by each convex portion 4 of the cylindrical portion 3a and is unlikely to fall off from the cylindrical portion 3a.

FIG. 3 shows another embodiment of the eyelet fitting of the present invention. In this eyelet fitting, an annular convex portion 7 is formed on the cylindrical portion 6a of the male die 6, and the diameter d of the convex portion 7 is made substantially equal to the inner diameter D of the female die 8. Also in this case, the female die 8 is caught on the convex portion 7 of the cylindrical portion 6a of the male die 6 and is unlikely to drop off.

[0018]

【effect】

 As described above, in the eyelet fitting of the present invention, since the edge of the male cylindrical portion is widened or a part of the male cylindrical portion is projected outward, the female die is hard to fall off.
