The present invention relates to a pair of synthetic resin snap coupling members that snap-fit two parts of a snap fastener, such as a snap button or a cord stop, used in clothes or a bag.

Conventional synthetic resin snap coupling members for snap fasteners, such as snap buttons, are disclosed in Japanese Utility Model Publication Nos. 39-L1309 on 1964, 4 and 30 and Japanese Patent Publication No. 43-4035 on 1968, 2 and 14 Is disclosed.

These existing snap engagement members consist of a male member with an annular stud protruding from one side of the base and an arm member with an annular socket on the base. By inserting an annular stud into the annular socket, the male and female members can be assembled together.

One problem with conventional snap engagement members is an arm. Care must be taken when assembling them because the male members are structurally different and must be distinguished from each other.

In view of the above problems of conventional snap coupling members, an object of the present invention is to provide a pair of snap coupling members that can be easily assembled in a simple and clear process without paying special attention.

According to the present invention, each pair of arms. A pair of snap engagement members of the same shape are provided, each comprising a base with male snap protrusions, the male snap protrusions being disposed opposite each other on one side of the coupling member and each laterally opposite to each other. Protruding protrusions, the female snap protrusions having a pair of locks arranged facing away from each other on the one side and protruding laterally toward each other, so that the protrusions The ends are to face each other.

When engaging the snap engagement members, the male snap protrusions on the base of one of them snap into engagement with the female snap protrusions on the base of the other coupling member, and the female snap protrusions on the base of the former coupling member. Are snapped into engagement with the male snaps at the base of the latter engaging member.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Like parts are designated by like reference numerals throughout the drawings.

FIG. 1 shows two snap fasteners L1 shown as snap buttons for merging the snap coupling members according to the first embodiment of the present invention. Each of the snap buttons L1 is made of synthetic resin and has an attachment portion 14 with a central stud 13 protruding from the back of the head L2, and made of synthetic resin and with a central insertion hole 15 intersecting. It consists of a snap engaging member with a base 16 extending therethrough.

The snap engagement member is fixed to the distal end of the stud 13 inserted into the insertion hole 15 with the cloth C clamped between the head 12 and the base 16, and the distal end of the stud 13 is fixed to the base. It is deformed into a flange 17 which engages the front face of 16 (see FIG. 5).

As shown in Figs. 1 and 2, the base 16 is in the form of a disc and there is a pair of male snap protrusions 19, a pair of female snap protrusions 20 and guide protrusions 21 on the front side, all of which are It extends from the attachment portion 14 and is actually elongated squares in shape. The male snap protrusion 19, the female snap protrusions 20, and the guide protrusion 21 are substantially the same height and protrude above the upper surface of the flange 17.

The male snap protrusions 19 have measuring surfaces 23 coincident with the first center line L1 extending in the radial direction across the base 16, respectively, and the male snap protrusions are located at the first center line L1. It is also vertically arranged symmetrically with respect to the second center line which extends radially across the base 16. The lengths of the male snap protrusions 19 are the same in the direction along the second center line L2. As shown in FIG. 3, the male snap protrusions 19 each have protrusions 24 at their outer edges. The protrusions 24 protrude outwardly from each other.

The arm snap protrusions 20 have measuring surfaces 26 coincident with the first center line, respectively, which are arranged symmetrically with respect to the second center line. The female snap protrusions 20 are arranged farther than the male snap protrusions 19 at the second center line L2, but the measuring surfaces 26 of the female snap protrusions are the measuring surfaces of the male snap protrusions 19. It is partially in contact with (23). The length of the arm snap protrusions 20 is the same in the direction of the second center line. Male and female snap protrusions 20 and 19 are equal in length to each other. As shown in FIG. 4, there are locks 27 at the inner edges of the female snap protrusions 20, which protrude laterally inwards toward each other. For example, the projections 24 of the male snap protrusions 19 on the base 16 of the snap engagement member at the top of FIG. 1 are the female snap protrusions on the base 16 of the other snap engagement member at the bottom of FIG. It can snap to the locking portions 27 of the (20). The protrusions 24 of the male snap protrusions 19 and the locks 27 of the female snap protrusions 20 have longitudinally opposite ends facing each other.

The guide protrusion 21 extends along the first center line L1 across the second center line L2 with the female snap protrusions 20 apart from the first center line L1. The length of the guide protrusion 21 is smaller than the distance between the opposite inner surfaces of the male snap protrusions 19.

On the outer periphery of the attachment portion 14 there is a projection 14a which positions the character group or direction pattern on the head 12 surface. Similarly, there is also a protrusion 16a at the outer edge of the base 16 of the snap connection member that determines the direction or position of the base 16 with respect to the piece of clothing C.

When the snap connection members mounted on each of the pieces of clothing C snap to each other as shown in FIG. 5, the snap coupling members are axially aligned and overlap each other, and the protrusions 16a are inserted into the insertion holes. It is arranged in the opposite position across the field 15. The bases 16 are then pressed against each other with the guide protrusions 21 on the bases 16 facing each other across the insertion holes 15. The male snap protrusions 19 of one of the bases 16 snap to the female snap protrusions 20 of the other base 16 and the female snap protrusions 20 of the one of the bases 16 The other base 16 snaps to the male snaps 19 (see FIG. 5). Guide protrusions 21 may not be necessary.

The snap engagement members are identical in structure to each other and may fit into each other when engaging the snap fasteners. The snap coupling members do not need to be distinguished from each other. Therefore, snap fasteners such as snap buttons 11 can be simply assembled without special assembly precautions. cancer. Since the measuring surfaces 26 and 23 of the male snap protrusions 20 and 19 are partially disposed adjacent to each other, the male snap protrusions of one of the bases 16 when the snap buttons 11 are engaged. The measuring surfaces 23 of 19 are gripped against the measuring surface 23 of the male snap protrusions 19 of the other base 16, and the female snap protrusions 20 of one of the bases 16. Measuring surfaces 26 of the other base 16 are gripped against the measuring surfaces 26 of the arm snap protrusions 20 of the other base 16. Thus, the snap coupling members, when assembled together, do not shake or move with each other.

As the snap coupling members are of the same shape, they can be cast into one type of mold and the molding machine for casting them requires only one absorber and chute.
