BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a button including a button body having a hollow portion and a mounting stud inserted into the hollow portion and caulking and fixing the tip thereof.

[0002]

2. Description of the Related Art Conventionally, a button body of a button of this type has a cylindrical metal cap having a flat central portion, a flat plate-shaped insert member, and a cylindrical shape with a flange for sandwiching the insert member with the metal cap. No. 60-65011 is a button constructed by inserting a mounting stud into the cylinder of the button base , fixing the tip of the mounting stud to the insert member and deforming it by caulking . Disclosed in the gazette
Has been .

The center of the back surface of the front plate forming the button body
A small recess is provided on the
Projected insert member, surface plate of this insert member
The button sandwiched between and the cylindrical button base with flange is actually fair
It is disclosed in JP-A-2-32081 .

[0004]

[Problems to be Solved by the Invention] The previously known button described above.
Is a flat plate when the mounting tacks are inserted into the cylindrical shape of the button base of the button body and the tips of the mounting tacks are brought into contact with the insert member and caulked and fixed.
Or, it has a protrusion with a diameter smaller than the mounting tack.
Therefore, the concentrated stress applied to the insert member causes the deformation of the metal cap itself, and the decorative body adhered to the surface of the metal cap is peeled off. However, there has been a problem that the amount of deformation of the metal cap becomes large and a crack phenomenon occurs in the synthetic resin decorative body.

Therefore, the present invention solves the above conventional problems .
Considering the time of crimping of the mounting studs into the button body, depending on stress concentration applied to the insert member, the insert member
It is an object of the present invention to provide a button which prevents deformation of the metal cap and the metal cap , and further prevents the phenomenon of peeling from the synthetic resin decorative body adhered to the surface of the metal cap and the cracking phenomenon of the decorative body. It is a thing .

[0006]

In order to achieve the above-mentioned object, the present invention has a button body 1 having a hollow portion, and a caulked fixing.
The button body 1 is thicker than the diameter of the pillar portion 17 of the mounting tack 11 protruding upward in the center.
A ridge 1 provided with a convex portion 12 and protruding around the convex portion 12
8 is provided with a metal cap 3 and a raised portion 13 that is aligned with the convex portion 12 on the surface, and has the same diameter as the raised portion 13 on the opposite surface.
A plate-shaped insert member 4 having a protruding portion 14 of
Consists of the insert member 4 from the flange 7 with Kino cylindrical button base portion 2 which is pinched between the metal cap 3, the main components of the adherent button decorative member 6 on the surface of the metal cap 3
I am trying .

Then, it is provided on the surface of the insert member 4 in a protruding manner.
The protruding portion 14 is a straight portion of the protruding portion 13 that is provided on the opposite surface.
Formed in a convex shape with a larger diameter than the diameter and a flat surface
It is a button .

[0008]

[Function] The insert member 4 of the button body 1 is provided with a metal cap.
By configuring 3 to match the inner surface of the convex portion 12, a mounting stud 11 to the button main body 1 during crimping, the mounting studs 11
The pillar portion 17 is inserted through the hollow cylindrical portion 9 of the button base portion 2 and comes into contact with the protruding portion 14 formed thickly in the center of the insert member 4, the tip of the pillar portion 17 is deformed, and the bent portion of the button base portion 2 is deformed. It is locked so that it does not come out to 10 . When mounting stud 11 abuts to deform the protrusion 14 of the insert member 4, but concentrated stress is applied such as the insert member 4 and the metal cap 3 receives a concentrated load at the entire surface of the matching, partially concentrated Not subject to load and insert member
4 of the convex portion 12 the inner surface of the raised portion 13 and the metal cap 3 is, if one follows the other side, the stress concentration integrally deformed, was added to the insert member 4, form the uneven shape
Evenly formed so that only the formed metal cap 3 is not deformed
Even if stress is applied to the metal cap 3,
It can be absorbed by the ridges 18 formed around the portion 12.
It is obtained by sea urchin.

[Effect of the invention] button of this invention is Ri configuration der as described above, in which the following effects by the configuration
There is .

The button according to the present invention is particularly located in the center of the button body.
Provide a protrusion that is thicker than the mounting tack that protrudes upward, and
A metal cap with a ridge around it, and a protrusion on the surface
Equipped with matching ridges, forming protrusions of approximately the same diameter on the opposite surface
By forming the the plate-shaped insert member, when crimping of the mounting studs into the button body, the insert member is collected
Since only the contact part of the stud is made thick,
Even if the sart member is a thin plate, it does not damage
Even duck concentrated stress is added, and the convex portion of the ridge and the metal cap of the insert member, one for changing integrally following the other, deformation hardly occurs in the metal cap, if stress acts However, due to the hollow ridge,
Le can be absorbed, and peeling <br/> bonding portion between the metal cap decorative body, or cracking phenomena occurs decorations
There is no effect .

The button in this invention is an insert.
The protruding part protruding from the member is thicker than the protruding part provided on the opposite surface.
A convex shape.
DOO in Therefore, the mounting studs when caulking, from the mounting studs
The load can be easily received and transmitted evenly, and
It has the effect of facilitating the deformation of the tip of the tack.
However, the effect of this invention is extremely remarkable .
