Abstract

PROBLEM TO BE SOLVED: To make it possible to eliminate the inconvenience when the ornamental base plate of a female type snap is made large in shape in order to enhance a design feel, i.e., the unsightly appearance resulted from inclination of this ornamental base plate and the consequent formation of a spacing between the base late and a clothing surface and to prevent the failure of the ornamental base plate regardless of its material. SOLUTION: This snap consists of a fitting body 6 which has an either female or male fitting part 6b on an annular base plate 6a, the ornamental base plate 7 which is extremely larger than this fitting body 6 and is ornamented on its surface and a sheet clamping base plate 8 which clamps the peripheral edge of the fitting body 6 and a flexible sheet 3 around this body by the ornamental base plate 7. Plural pieces of engaging parts 8b penetrating the sheet clamping base plate 8 in the sheet clamping direction are formed on the sheet clamping base plate. On the other hand, the ornamental base plate 7 is provided with detaining bodies 7a which penetrate the flexible sheet 3 and are fitted and detained to the engaging parts 8b.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a male or female snap constituting a snap fastener.

[0002]

2. Description of the Related Art The above-mentioned snap is to be attached to a seam such as a front garment or cuff of clothes. Generally, a female snap is provided on the outer fabric of the seam,
A male snap is provided on the inner fabric. This is not necessarily specified, and a female snap may be provided on the outer fabric of the seam, but for convenience sake, the description will be continued on the assumption that the outer fabric is provided with the female snap.

As these male and female snaps, there are synthetic resin snaps having the structure shown in FIG. These male and female snaps 1 and 2 are structurally the same, and the male snap 1 has a flexible sheet (for example, cloth for clothes) 3 on the back side of the dish-shaped substrate 4a. A rivet member 4 in which a protrusion 4b that is pierced from one side is continuously provided, and a male fitting body 5 in which a male fitting portion 5c is formed in the central portion of an annular substrate 5a. The female snap 2 is formed on the substrate 11a. It is composed of a rivet member 11 in which a protrusion 11b is continuously provided on the back surface side, and a female fitting body 6 in which a female fitting portion 6b is formed in a central portion of an annular substrate 6a.

The male fitting portion 5b has a locking portion a bulged on the outer surface of the distal end of the annular peripheral wall thereof, and the female fitting portion 6b has a male fitting portion 5b. The protruding portion b that releasably locks the locking portion a is bulged. Further, through holes 5c and 6c for penetrating the projections 4b and 11b pierced by the flexible sheet 3 and caulking are formed in the central portions of the bottom walls of the male and female fitting portions 5b and 6b. .

By the way, giving a design feeling to the board surface of the rivet member 11 of the female snap 2 which is easily noticeable in the state of wearing clothes leads to an improvement in the design and fashion of the clothes. The substrate 11a is made to be significantly large so as to be easily noticeable, and then the substrate 1
The surface of 1a may be subjected to engraving decoration such as a pattern or mark, or coloring decoration.

The male snap 1 in this can be attached to the flexible sheet 3 by an automatic snap striking machine. That is, the rivet member 4 and the male fitting body 5 are housed in a rotary hopper, and they are taken out from the rotary hopper while being aligned in a fixed posture, and are individually fed by a chute to a rivet receiver and a fitting body driving tool, and between them. The flexible sheet 3 is inserted and pressed against the male fitting 5, and the projection 4b of the rivet member 4 is relatively pierced into the flexible sheet 3 from one side, and this is inserted through the through hole of the male fitting 5. The male snap 1 can be automatically attached to the flexible sheet 3 by projecting it from 5c and crimping the projecting tip of the projection 4b so as to expand and deform it by striking.

The female snap 2 is usually attached to the flexible sheet 3 by a manual or semi-automatic machine that artificially supplies the rivet member 11 to the rivet receiver. That is, in order to prevent the engraving decoration on the substrate surface from being scratched by the impact of the tip of the protrusion, or because the shape of the decorative substrate 11a is, for example, an elliptical shape or a rectangular shape, As the rivet receiver, one that conforms to the surface shape of the decorative substrate 11a is required. Therefore, since the rivet member 11 cannot be automatically supplied to this rivet receiver, the supply of the rivet member 11 is not possible. A manual or semi-automatic attachment form is used to artificially perform.

[0008]

However, the decorative substrate 1
To prepare a large number of rivet receivers according to the complicated surface shape of 1a and according to the type of female snap, the equipment cost is very high, which leads to an increase in the cost of clothes. There was a problem. For example, the decorative substrate 11a
Even if a large number of rivet receivers that match the surface shape of the decorative substrate 11a are prepared, the decorative substrate 11a may be impacted by the impact of the protruding tip of the protrusion 11b depending on the material of the decorative substrate 11a.
Was sometimes damaged.

When the decorative substrate 11a is remarkably large, the decorative substrate 11a is attached to the cloth 3 of the garment by the female fitting 6 locally, and the decorative substrate 11a becomes heavy. When wearing the
The upper side of the decorative substrate 11a tilts forward so as to separate from the fabric surface, and a gap S may be formed between the decorative substrate 11a and the fabric surface, which may look unnatural, and the decorative substrate 11a of the female fitting 2 is easily noticeable. There is also a problem in that making the size larger and giving it a design feel makes it unattractive, and rather impairs the design and fashionability of clothes.

In the drawing, the state where the female snaps 2, 1 are tilted forward when the male and female snaps 2, 1 are disengaged is shown. However, it will be easily understood that the male and female snaps 2, 1 are united and fall forward.

The present invention has been made with the above points in mind, and the purpose thereof is to use a snap attachment technique which is completely different from that of the prior art, without requiring any rivet receiver. A large decorative substrate can be attached to the flexible sheet in a state where there is no unnatural inclination or gap, and moreover, the decorative substrate can be prevented from being damaged regardless of the material.

[0012]

The snap according to the present invention, which has achieved the above-mentioned object, is a fitting body provided with one male and female fitting portions on an annular substrate, and is significantly larger than this fitting body. And a sheet sandwiching substrate that sandwiches the peripheral portion of the fitting body and the flexible sheet around it with the decorative substrate, and the sheet sandwiching A plurality of engaging portions are formed on the board so as to penetrate therethrough in the sheet sandwiching direction, and a locking body that penetrates the flexible sheet and is fitted and locked to the engaging portions is formed on the decorative board. The point is that it is provided.

A female snap 2 is attached to the outer fabric (flexible sheet) 3 such as a pocket, and a male snap 1 is attached to the inner fabric 3, so that the clothes can be seen in a state where the clothes are worn. The surface of the female snap 2 is provided with engraving-like decorations such as patterns and marks.

The male snap 1 is a back side of the dish-shaped substrate 4a having a rounded outer shoulder portion (the cloth material 3 side of clothes,
Hereinafter, the fabric 3 side of the garment will be referred to as the back side. ) In the center of
A rivet member 4 made of synthetic resin integrally formed with a sharp projection 4b having a circular cross section whose tip end is expanded and deformed by impact.
And a male fitting 5 made of synthetic resin, which is integrated with the rivet member 4 and attached to the cloth 3 of clothes,
The male fitting 5 has a through hole 5c formed in the center of the annular substrate 5a for inserting the protrusion 4b of the rivet member 4, and the through hole 5c is formed on the front surface side of the annular substrate 5a. The core-shaped cylindrical male fitting portion 5b is integrally formed, and the locking portion a is bulged on the outer surface of the distal end side of the annular peripheral wall of the male fitting portion 5b.

The female snap 2 includes female fittings 6 each made of synthetic resin, a decoration board 7 which is significantly larger than the female fittings 6 and whose surface is decorated, and the female fittings 6. A sheet sandwiching substrate 8 which is locked to the outer surface of the peripheral edge of the mold fitting body 6 and sandwiches the female fitting body 6 and the flexible sheet 3 around the female fitting body 6 with the decorative substrate 7.

The female fitting 6 is constructed as follows. That is, the central portion of the annular substrate 6a is recessed on the back side to form a female fitting portion 6b, and the female fitting portion 6b is provided with an inner surface portion on the upper side of the peripheral wall of the male fitting portion 5b. The ridges b that detachably lock the locking portion a are bulged at predetermined intervals in the circumferential direction, and the female base fitting is made to correspond to the ridges b and the annular substrate 6a. Arc-shaped slits c around the portion 6b are formed, and radial ribs d are formed on the back surface side of the annular substrate 6a and between the slits c and c.

The annular sheet sandwiching substrate 8 is a female fitting 6
Through hole 8a with locking portion e along the outer surface shape of the peripheral edge of
And the outer surface of the peripheral portion of the female fitting body 6 is locked to the locking portion e so that the sheet-side surfaces of both of them 8 and 6 are flush with each other. There is. Further, on the sheet sandwiching substrate 8, a plurality of engaging portions 8b with locking step portions penetrating in the sheet sandwiching direction are formed at predetermined intervals in the circumferential direction.

On the other hand, on the sheet-side surface portion of the decorative substrate 7, a locking body 7a which penetrates the flexible sheet 3 and is fitted and locked to the engaging portion 8b is continuously provided. This locking body 7a
Has a hook-shaped hook body f, which is slightly larger than the hole diameter of the engaging portion 8b, at the tip, and an axial slit h is formed in the hook body f to form the flexible sheet 3 The hook body f can be elastically deformed in the radial direction so that the hook body f penetrating through can be expanded at the large diameter hole of the engaging portion 8b, and the hook body f is engaged by this expansion. By locking to the locking step of the mating portion 8b, the locking body 7 from the engaging portion 8b
The escape of a is impossible.

Under the fitting and locking which cannot be pulled out,
The sheet sandwiching substrate 8 is made to conform to the outer shape of the decorative substrate 7 so that the sheet sandwiching substrate 8 does not project from the peripheral portion of the decorative substrate 7, but the peripheral portion of the decorative substrate 7 is slightly different. The sheet sandwich substrate 8 may be projected from the above. Alternatively, when the decorative substrate 7 has an elliptical shape or a rectangular shape, the sheet sandwiching substrate 8 may be formed in a circular shape as large as possible, for example, by making the minimum width of the decorative substrate 7 a diameter.

The above male snap 1 is attached to the flexible sheet 3 by, for example, an automatic snap striking machine.
That is, the rivet member 4 and the male fitting body 5 are taken out from the rotary hopper in a fixed posture, fed individually into the rivet receiver and the fitting body driving tool through the chute, and the rivet member 4 is driven into the rivet. Member 4
