Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention arranges a fitting body having a through hole at the center of a male or female fitting portion on one side of a flexible sheet, and from the opposite side of the flexible sheet. The present invention relates to a snap fastener in which a projection of a driven rivet member is inserted into the through hole to be caulked.

[0002]

2. Description of the Related Art A snap fastener of this type can be manually attached to a flexible sheet (for example, cloth for clothes), but it is often attached by an automatic machine. To mount the snap fastener by an automatic machine, the male snap fitting or female snap fitting and the rivet member are adjusted to a fixed posture by the rotary hopper and chute, and fed into the upper and lower driving tools separately, and the middle flexible. By driving the upper and lower driving tools up and down with the sheet interposed, the protrusion of the rivet member is pierced through the flexible sheet and inserted into the through hole of the fitting body, and the protruding tip end of this protrusion is struck. This is performed by crimping so as to expand and deform the diameter, and the fitting body and the rivet member are integrally connected with the flexible sheet interposed therebetween.

By the way, when the snap fastener is attached to the overlapping portion of the clothing, the head of the rivet member of either the female or male snap always appears on the front surface of the clothing. Therefore, conventionally, the color of the rivet member has been modified according to the design and color of the clothes, or various patterns and marks have been added to the head of the rivet member to improve the design and fashionability. However, there were the following problems.

That is, as a pattern to be attached to the head of the rivet member, a pattern in which the vertical and horizontal relations are naturally limited (for example, if the pattern is a yacht or an automobile, it should be kept horizontal from the balance aspect). It is desired, and if it is a standing tree pattern, it is desired to keep the vertical state.),
Even if you select a pattern with other directions, it is impossible for an automatic machine to attach snap fasteners to clothes so that the directions of the patterns are aligned. However, for example, the yacht is tilted, the car is turned upside down, or the directions of various patterns are not uniform, which adversely affects the design.

In addition, because the head of the rivet member is limited to a circular shape or a regular quadrangle because it is loaded into an automatic machine, the size of the head is also limited by the supply to the driving tool by the rotary hopper and chute. Therefore, various designs cannot be selected, and further, it is necessary to prevent the deformation due to the pressure contact with the head receiving surface when the projection end of the rivet member is hit by the driving tool to be expanded and deformed. It was not possible to attach a prominent three-dimensional pattern to the mark, and the degree of marking was limited.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and enables a wide variety of directional designs even when the snap fastener is attached by an automatic machine. The purpose of the invention is to provide a snap fastener.

A snap fastener in which a protrusion of a rivet member is inserted into the through hole to be caulked, and a large number of recesses are formed at regular intervals on the outer periphery of the head of the rivet member, while the rivet member is formed. A decorative member is provided on the back surface of a decorative body having a size that covers the head of the head, and a plurality of fitting locking portions that are fitted into the recess and engage with the corners on the back surface side of the head are provided in series. The decorative member is attached to the head of the rivet member via the fitting and locking portion.

[0008]

According to the above construction, the projection of the rivet member driven from the opposite side of the flexible sheet is struck to attach the male snap or the female snap to the flexible sheet, and then the rivet member in this snap. A decorative member will be attached to the head. In this case, by appropriately selecting a large number of recesses formed on the outer periphery of the head and fitting the fitting locking portions of the decorative member into the recesses, the decorative member is attached to the head of the rivet member. Since the rivet member is prevented from being rotated, the decorative member can be attached with a predetermined directionality regardless of the direction of attachment of the rivet member.
