Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for attaching buttons to fabric without using threads.

[Conventional technology]

Generally, buttons are attached to fabric using thread, but buttons that can be attached without using thread have been proposed (for example, Japanese Utility Model Publication No. 56-30010).

The button has a needle with a disc-shaped plate integrated into the plastic button body, and the needle is pushed into the fabric, and the tip of the needle is heated with an ironing iron or the like to form a lump, and the fabric is pressed into the circle. The button is attached to the fabric by holding it between the plate and the block.

[Problem to be solved by the invention] However, in order to attach the above-mentioned button, the tip of the button is simply passed through the fabric and then heated with an iron or the like, so the shape of the resulting lump is not constant and therefore the button is difficult to install accurately and reliably. Moreover, since each attachment must be attached using an ironing iron, etc., it is troublesome and inefficient.

The present invention has been devised in view of the above, and its purpose is to provide a method for attaching buttons to fabrics accurately and reliably, and to facilitate and efficiently attach buttons.

[Means to solve the problem]

The structure of the present invention to achieve the above object is that the thermoplastic needle of the button is provided with a thermoplastic needle integrally having a disc-shaped plate in the button body, and the tip of the thermoplastic needle is heat-treated to form a lump, and the fabric is shaped into a disc-shaped In a device for attaching a button to a piece of fabric by sandwiching the button between a plate and a block, a casing to which a heat transfer tube is attached to a support tube of a pedestal via a pressure spring and a cylinder is placed on the pedestal, and the casing and the pedestal are A button clamping plate fixed to the support tube is arranged in the seat, a molded recess is formed on the lower surface of the heat transfer tube, and a groove into which a thermoplastic needle can be loosely inserted is formed in a portion of the button clamping plate corresponding to the molded recess. At the same time, a recess into which the button body is inserted and guided is formed on the back surface of the button clamping plate.

[Effect]

A button is placed upside down on a pedestal, held by a button clamp plate, the thermoplastic needle penetrates the fabric, and the casing with the heat transfer tube attached is lowered downward against the spring force of the push spring. The tip of the plastic needle softens within the molding recess to form a precisely shaped mass, and the button is attached by sandwiching the fabric between the mass and the disc-shaped plate. When the user releases the casing after attachment, the casing is pulled back up by the restoring force of the push spring. By repeating this operation, the button attachment work is performed continuously.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

Figures 1 and 2 are examples of buttons applicable to the present invention.
FIGS. 3 to 9 show an embodiment of the present invention.

In the figure, 1 is a button applied to the present invention, and 2 is the button body of the button 1. The button body 2 is made of cylindrical wood, for example, with a diameter of 10 mm.
At the center of the back side, a disc-shaped plate 3 with a thickness of 0.1 mm and a diameter of 3 mm is placed at a distance of 1 mm from the button body 2.
Thermoplastic, weather-resistant and strong diameter
A 0.7 mm nylon needle 4 is attached.
In this case, the diameter of the needle 4 can be selected depending on the size of the button body 2, but the diameter of the button body 2 is 12 mm for strength reasons.
If the diameter is within mm, approximately 0.7 mm is sufficient, and if the diameter of the button body 2 is 12 mm or more, approximately 1 mm is sufficient.
Further, in consideration of ease of attachment to the fabric 5, fastening to the button hole 6, etc., the diameter of the needle 4 is preferably set to such a dimension.

Since the button 1 is used to insert and attach the needle 4 into the fabric 5, unlike a normal button, the button body 2 does not have a hole through which a thread can be passed and attached to the fabric. Further, the disc-shaped plate 3 has an eighth
As shown in the figure, when the button 1 is inserted into the fabric 5, it functions as a fabric retainer, that is, to maintain a slight gap between the button body 2 and the fabric 5.
If it is formed with a thickness of 0.1 to 0.3 mm and a diameter of 3 to 5 mm depending on the material, it will sufficiently perform its function. The distance between the button body 2 and the disc-shaped plate 3 depends on the material and thickness of the fabric on the button hole side, but it is generally 1 mm when the diameter of the button body 2 is within 12 mm, and 1 mm when the diameter of the button body 2 is within 12 mm. When the length is 12 mm or more, it is preferable for the appearance to be formed with an interval of 2 mm, and it is also easy to hang the button 1 in the button hole 6, and it is also easy to fasten the fabric 5 into which the button 1 is inserted and the fabric 5 on the button hole 6 side. be.

The needle 4 is loosely inserted into the groove 25 with the button clamp plate 23 of the recess 26b interposed therebetween, and the heat exchanger tube 1 is inserted.
The button 1 is held upside down on a button clamping plate 23 via a disc-shaped plate 3 at a position corresponding to 9. Next, the cloth 5 to which the button 1 is to be attached is applied to the needle 4 and penetrated to bring it into close contact with the disk-like plate 3, and the adhesive 30 is dripped onto the cloth 5 to adhere the disk-like plate 3 and the cloth 5. Then, the connecting pipe 16 of the mounting device 8 is pushed down in the direction of arrow A against the spring force of the push spring 11 to move the casing 15 and melt the thermoplastic needle 4 in the molded recess 22 of the heated heat transfer tube 19. At the same time, press the fabric 5, and then press the spring 1.
When the casing 15 is pulled up in the direction of arrow B by the restoring force of 1, the thermoplastic needle 4 melts and a resin mass 4a of a certain shape is formed as shown in FIG. Since the fabric 5 is held between the resin mass 4a that is in close contact with the fabric 5 and the disc-shaped plate 3, the button 1 can be easily and accurately inserted into the fabric 5 in a very short time without using threads. can be done. Due to the function of the disc-shaped plate 3, a required distance is maintained between the button body 2 and the fabric 5, so that the fabric 5 and the fabric 7 can be fastened together easily. In addition, traditional yarns (cotton,
Since the diameter of the needle 4 is larger than that of threads made of silk, linen, nylon, etc., and it has elasticity, it has a strong tensile strength and is therefore difficult to break and can withstand washing well.
