Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a button with a simple structure that can be easily and firmly attached to clothing without using thread.

[Conventional technology]

Conventionally, buttons have been sewn using thread, but attaching buttons in this manner requires time and effort and is low in productivity. In order to solve these problems, the applicant filed a patent application in
033, we proposed a button that consists of a button body, a leg body, and an indigenous body, and that can be attached to clothing with a so-called one-touch operation.

However, in this case, the leg body is attached to the button body by penetrating the fastening body into the leg body, and the structure is complicated, and the leg body forming the neck wrap part is small. Since it is also a component, the strength of the attachment between the leg body and the button body tends to be somewhat insufficient.

Therefore, in Japanese Patent Application No. 59-226438, the present applicant proposed a button in which the attachment strength between the button body and the leg body can be improved by fixing the button body and the leg body by rotational friction welding.

[Problem that the invention seeks to solve]

Therefore, although this product can solve the above-mentioned problems, it requires a rotating device, which requires a relatively large amount of installation work, and tends to be low in productivity.

On the other hand, adhesives have made remarkable progress in recent years, and adhesives that have high strength and can bond various materials in a short time have been developed.

An object of the present invention is to provide a button that can easily and firmly attach the button body and the leg body by using an adhesive, and that can solve the above-mentioned problems.

[Means for solving problems]

Hereinafter, one embodiment of the means of the present invention capable of achieving the above-mentioned objects and solving the problems will be described with reference to the drawings.

In the figure, the button 1 of the present invention is composed of a button body 2, a leg body 3, and a fastening body 4, and the button body 2 and the leg body 3 are fixed using an adhesive.

The button body 2 is made of natural materials such as safes, corners, glass, and ceramics, or acetal resin, acetate, polyester synthetic resin,
The base body 5 has a well-known shape such as a disk shape formed by cutting or molding using an artificial material such as acrylic resin, urea resin, epoxy resin, or ABS resin. In addition, a cylindrical recess 9 is formed in the center of the lower surface of the base body 5, with the end of the cylindrical surface 7a extending toward the inner depth with the same diameter connected to the inner surface 7b-C parallel to the lower surface of the base body 5. . In this example, the diameter D1 of the recess 9 is 3 to 7R1, for example, about 5fi, and the depth dimension L
1 is formed to be 1.5 to 4ws, for example, about 2.5fi.

The leg body 3 is a molded product made of strong, elastic, and creep-resistant synthetic resin such as polyacecool resin or polycarbonate resin, and has a circular cylindrical shape that extends from the lower end and has an inner hole 11 consisting of a square hole. At the upper end of the base 12, the base 1
A cylindrical insertion part 13 having a diameter larger than that of the base part 12 is arranged concentrically, and a flange 14 is provided on the outer periphery of the upper and lower end of the base part 12.

The base 12 has a U-shaped split with side edges at both ends of the upper side.
2o and 2o are formed facing each other. The upper edge passes through the lower end of the flange 14, and the side edges are located at the side edges of the inner hole 11 facing each other, with the lower end reaching slightly above the flange 15. Therefore, the grooves 20.20 are formed by a pair of opposing elastic pieces 22.
22 is formed. Further, on the inner surface of each elastic piece 22, a meshing portion 23 is formed that extends beyond the side surface, faces the inner hole 11, and projects into the interior thereof.

In this example, the engaging portion 23 has a substantially horizontal locking surface 24 at its upper portion.
It is provided with multi-stage sawtooth-shaped convex portions 24 having slopes 24C extending obliquely outward from their inner ends.

The button body 2 and leg body 3 are fixed by bonding the insertion portion 13 to the recess 9 using adhesive A as described above.

Adhesive A in this example is an instant adhesive based on cyanoacrylate, and a low-whitening type is used to prevent whitening around the adhesive site caused by evaporation and re-deposition of the base. There is. Note that additives are added to the adhesive A, including a boiling point elevating agent that increases the boiling point and prevents evaporation, and a curing agent that increases the polymerization rate. Therefore, evaporation of the adhesive A is suppressed by raising the boiling point and rapidly curing, and as a result, whitening can be prevented and the button body 2 and the leg body 3 can be bonded together with good appearance.

As adhesive A, synthetic resin adhesive such as epoxy resin, polyurethane resin, butyral resin, acrylic resin, etc.
Also, synthetic rubber adhesives and the like may be used as appropriate depending on the material.

Further, as the additives, alkyl such as methyl is used as a boiling point elevating agent, amines, polyamide, acid, etc. are used as a curing agent, and hydrous silica gel, etc., which absorbs vaporized gas of a solvent, etc. are also used.

In addition, the adhesive A is applied to the insertion part 13, for example, and then the insertion part 13 is inserted into the recess 9, so that the inner surface 7 of the recess 9 is coated with the adhesive A.
b and the end surface of the insertion portion 13 and between the cylindrical surface 7a and the insertion portion 1
The button body 2 and the leg body 3 are firmly fixed by bonding between the three side surfaces. Note that fixation can be performed for about 1 to 3 seconds.

The fastening body 4 has a shaft 28 protruding from approximately the center of the table piece 27. The shaft rod 28 is a prismatic body with a rectangular cross section that can be inserted into the inner hole 11, and a cone-shaped insertion piece 29 with a sharp tip is provided at its upper end through a small-medium cut portion 28A. Also, on each side of the shaft rod 28 facing each other, a locking surface 30a and a slope 3 are provided.
A pawl portion 31 is formed in which grooves 30 having a shape opposite to that of the convex portion 24 and into which the convex portion 24 fits are provided in multiple stages. Note that the groove portion 30 has a locking surface 30a that is connected to the locking surface 2.
It is formed slightly longer than 4a. Further, the shaft rod 28 is molded integrally with the substantially elliptical base piece 27 and the insertion piece 29 using the same material as the leg body 3. Note that when the shaft rod 28 is pressed against the lower surface of the flange 15 of the leg body 3 and the stand piece 27 with the clothing C sandwiched therebetween, its pawl portion 31 can be engaged with the meshing portion 23, and its upper end portion can be The length is set to reach the extension of the inner hole 11.

The stand piece 27 also has a needle-like pin body 32 around the shaft rod 28.
