Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to buttons for clothing, etc., in which the main body of the button and the rivets are crimped and fixed, such as buttons for jeans, and in particular, the invention relates to buttons for clothing, etc., in which the main body of the button and the rivets are crimped and fixed, such as buttons for jeans. The present invention relates to a button for clothing, etc., in which a column is inserted under pressure, and the tip of the column is deformed by applying pressure to a plate provided inside the button body, thereby crimping and fixing the button body and the stud.

Prior Art This type of button generally has a body with a plate-shaped flange integrally formed at the upper end of an outer cylinder that is integrated with an inner cylinder at the bottom, and a plate is provided on the flange of this body, and a cap is provided. is attached to form a button main body, the pillar part of the rivet is inserted into the inner cylinder of the button main body, and the tip side of the pillar part is pressed against the plate to deform it. The portion is crimped and fixed to the upper end of the inner cylinder.

However, in conventional buttons of this type, the plate is a flat disk, so when the body and cap are loosened, the plate can move between the body and the cap, and as a result, the plate can be moved between the body and the cap. The disadvantage is that the plate collides with the body or cap when attached to the vehicle, producing a sound, especially a metallic sound.

In addition, this type of button is generally made of iron, such as carbon steel, which is harder than the rivet, in order to prevent the plate from deforming when the button body and the rivet are fastened together. However, if the plate is movable relative to the body or cap, the plating peels off as the plate moves, causing the plate to rust and staining clothes.

Further, a button has been proposed in which the center of the plate is bulged and the bulge is fitted into the outer cylinder of the body. However, even with this button, it is difficult to keep the plate and body fixed at all times, and the plate often moves, causing noise.

Purpose of the invention The object of the invention is to provide a button for clothing, etc., in which the plate does not move relative to the body and the cap, and the plate can be manufactured easily and inexpensively.

Structure of the invention According to the invention, the above object is to form at least three conical protrusions at equal intervals on one surface of the plate on a circle that is approximately the same as the inner peripheral surface of the upper end of the outer cylinder of the body. This is accomplished by bringing the sloped portions of the conical projections into contact with the inside of the upper end of the outer cylinder, and preventing the plate from moving by each conical projection.

Embodiments Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

The button main body A shown in FIGS. 1 and 2 includes a body 1, a cap 2 fitted to the body 1,
It is composed of a plate 3 provided between a body 1 and a cap 2.

The body 1 has an outer cylinder 5 and an inner cylinder 6 concentrically integrated at the bottom 4, and integrally has a dish-shaped flange part 7 at the upper end of the outer cylinder 5. The inner cylinder 6
is made lower than the outer cylinder 5, and an outwardly bent portion 8 is formed at the upper end. An annular rib 9 is formed on the flange portion 7 to be concentric with the outer cylinder 5, and a peripheral edge portion 10 is bent upward.

The cap 2 is formed of a spherical plate part 12 and a peripheral wall part 13 extending downward from its outer periphery, and the plate part 12 is curved with a radius of curvature larger than the diameter of the cap 2. The cap 2 has an inner diameter slightly larger than the outer diameter of the flange portion 7 of the body 1, and after being placed over the flange portion 7, the peripheral wall portion 13 is deformed inward by pressing or the like. Attach it to body 1. A tongue piece 14 is formed on the cap 2 to determine the direction when crimping and fixing a stud B, which will be described later, to the button body A.

The plate 3 is usually circular, but as shown in FIGS. 3 and 4, the plate 3 may have a hexagonal shape or other polygonal shape. Further, in the center of the plate 3, three conical projections 16 are formed at equal intervals on a circle 15 having approximately the same size as the inner diameter of the upper end of the outer cylinder 5 of the body 1. The inclined portion of each conical projection 16 contacts the upper inner surface of the outer cylinder 5 to prevent the plate 3 from moving between the body 1 and the cap 2. If the plate 3 is circular, it should be made to have approximately the same size as the inner diameter of the flange portion 7 of the body 1, and if it is polygonal, the interval between the corners should match the inner diameter of the flange portion 7 of the body 1. Therefore, movement of the plate 3 can be doubly prevented.

Each pyramidal projection 16 has a pyramidal shape, a conical shape, etc.
Any shape having an inclined portion may be used. Such a conical projection 16 can be formed by punching the plate 3 from one side to the other side by punching or the like, or can also be formed by injection molding.

The stud B used for the button main body A has a disk-shaped head 21 (FIG. 5) and a column 22 extending from the center of the head 21. The head 21 has a plurality of small protrusions 23 formed on the surface facing the column 22, and the surface opposite to the column 22 is a flat surface.
The base portion of the column portion 22 located on the head 21 side has a cylindrical shape with approximately the same diameter as the inner diameter of the inner cylinder 6 of the button main body 1, but the tip portion has a sharp apex portion 24 that is the most distal end thereof. It is formed into a pyramidal (or conical) shape slightly offset from the centerline 25 of the columnar portion 22 .

In addition, when the rivet 20 is a rivet for fabric with a hole for the rivet insertion, the tip does not necessarily have to be a sharp apex 24 and may be flat.

As shown in FIG. 6, the button main body A and stud B are assembled in such a state that the column part 22 of the stud B is pierced through the fabric C of the clothing and inserted into the inner cylinder 6 of the button main body A. By pressurizing the button main body A and the stud B with a press or the like, the tip portion of the pillar portion 22 is pressed against the plate 3 and deforms toward the recess 28 , and this deformed portion 32
is crimped and fixed in a state where it is locked to the bent portion 8.

According to this button, the plate 3 has three conical protrusions 16 on the circle 15 at its center, and the inclined part of each conical protrusion 16 is in contact with the inner surface of the upper end of the outer cylinder 5. Even if the tightening condition of body 1 and cap 2 becomes loose, the plate 3
movement is prevented. Further, since the plate 3 is made to have approximately the same size as the flange portion 7 of the body 1, the plate 3
It abuts on the inner surface and thus also prevents movement of the plate 3 relative to the body 1 and the cap 2.

Note that the present invention is not limited to the above-mentioned embodiment, and for example, at least three conical projections 16 may be formed.

Effects of the invention As described above, the present invention forms at least three conical protrusions at equal intervals on one side of the plate on a circle of approximately the same size as the inner peripheral surface of the upper end of the outer cylinder of the body. Since the inclined portion of each conical projection is brought into contact with the inner surface of the upper end of the outer cylinder, each conical projection engages with the outer cylinder and the plate does not move relative to the body or the cap 2.
Therefore, no metallic noise is generated as the plates move, and the plating on the plates does not peel off.
Further, each conical projection can be easily formed by punching using a press or the like or by injection molding, and therefore manufacturing is easy and inexpensive.
