Abstract

(57) [Summary] [Purpose] To provide a new clothing button which is devised so that a jagged point of a male rod of a sewing member is sharply configured to be sufficiently locked in a hole. [Structure] A zinc alloy sewn member 4 having a male rod 2 having a jaggedness 1 for preventing slippage and rotation on the outer peripheral surface on the back side, and having a hole 3 for sewn into clothes on the surface, and a center on the back Female hole 5
And the hard plastic button body 6 having the above are fixed to each other by press-fitting the male rod 2 into the female hole 5 and locking the jagged 1 on the inner peripheral surface of the female hole 5 in a non-removable and non-rotatable manner. It is a thing.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a clothing button having a sewing hole.

[0002]

[Prior art]

 Conventionally, Japanese Utility Model Publication No. 61-30487 discloses a button of a type in which the button knives are fixed to clothes by engaging the knurled rivets with the circumferential surface of the hole.

[0003]

[Problems to be solved by the device]

 The studs for the buttons described in the above-mentioned prior art are currently manufactured by a molding method or a forging method such as a heter bolt. For this reason, the jagged point edge looks sharp in the report, but it is not so sharp in reality. This lack of sharpness is one of the causes for insufficient locking of the button body to the hole.

It is an object of the present invention to provide a new dressing button which is designed so that the notched point is sharply configured so as to be sufficiently locked in the hole.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the dressing button according to the present invention has a male rod 2 having a notch and a rotation preventing jaggedness 1 on the outer peripheral surface integrally with a back surface, and having a hole 3 for sewing clothes on the front surface. A zinc alloy sewing member 4 and a hard plastic button main body 6 having a female hole 5 in the center of the back surface are press-fitted with a male rod 2 into the female hole 5 so that the notch 1 is formed on the inner peripheral surface of the female hole 5. They are fixed to each other by being locked so that they cannot be removed and cannot rotate.

[0006]

【Example】

 In the first embodiment shown in FIGS. 1 and 2, a male rod 2 having a notch 1 on its outer peripheral surface and a notch 1 for preventing rotation is integrally provided on the back side surface of the collar 8 by the following manufacturing method using a zinc alloy. A sewing member 4 having a sewing hole 3 for clothes (not shown) on the front side of the collar 8 is formed, and, separately from this, a female hole 5 is formed in the center of the back surface using hard plastic. The button body 6 is configured, and the male rod 2 of the sewing member 4 is press-fitted into the female hole 5 of the button body 6 so that the notched portion 1 is locked to the inner peripheral surface of the female hole 5 so as not to be extracted and to be rotatable. As a result, they are fixed to each other, and the back surface of the collar portion 8 is brought into pressure contact with the back surface of the button body 6.

The second embodiment shown in FIG. 3 is a case button in which the button body 6 is covered with a wrapping material 9 such as cloth or leather and the edges of the wrapping material 9 are clamped by the collar portion 8.

4 to 6 show a manufacturing process of the sewing member 4. That is, first, as shown in FIG. 4, a semi-finished product 12 integrally including a ring portion 10 for forming a sewing hole 3 on the front side surface of a collar portion 8 and a round columnar male rod forming portion 11 on the back side surface. Is cast and formed with a zinc alloy, and then the round-column nourishing male rod component 11 in the semi-finished product 12 is passed through the gap 14 between the rolling dice 13 to form the notched portion 1 on the portion 11, and thus the male rod 2 with the notched portion 1 is formed. The sewn member 4 is completed.

[0009]

[Action]

 Since tin alloys and lead alloys are soft, they are unsuitable for casting and molding, and aluminum alloys and brasses have high melting temperatures and are not preferable for casting and molding small products. Therefore, the present inventor has devised the present application by paying attention to a zinc alloy having a melting temperature of around 400 ° C. That is, after casting a semi-finished product that integrally has a round columnar male rod component on the back surface by casting with a zinc alloy, make a serration with a rolling die for the round columnar male rod component of the semi-finished product. This makes it possible to manufacture products with no parting line and sharp jagged edges.

Even if the semi-finished product may have a parting line, this part disappears due to the jaggedness caused by the rolling die. In addition, the knurled tip is formed by rolling, and is made much sharper than the knurling by casting.

[0011]

[Effect of device]

 The garment button according to the present invention has a male rod 2 having a notch 1 on the outer peripheral surface and a jaggedness 1 for preventing rotation and an integrally formed back rod, and has a zinc alloy sewing member 4 having a sewing hole 3 for clothing on the surface. And a hard plastic button body 6 having a female hole 5 in the center of the back surface thereof. The male rod 2 is press-fitted into the female hole 5 so that the notched portion 1 cannot be pulled out and cannot rotate on the inner peripheral surface of the female hole 5. Since they are fixed to each other by stopping, the jagged tips are remarkably sharp and sufficiently locked in the holes, which has the excellent effect of completely achieving the intended purpose. It is a thing.
