摘要:
A female member (1) of a snap fastener includes a main body (2) made of a metal and having a cylindrical tube portion (23) and a dish-shaped portion (22), a resin spring (3) housed in the main body (2), and a surface covering member (4) crimped onto the cylindrical tube portion (23). The resin spring (3) is a resin plate that can be housed in the main body (2), and the resin plate has a slot (35, 35A, 35B, 35C) at a central portion thereof. The cylindrical tube portion (23) has a support portion for the resin spring (3), and the resin spring (3, 3A, 3B, 3C) is fixed in position by the support portion.

From the "face" side of the base (12) of the male part (4), an engagement protrusion (18) extends directly upwards in the direction of the engagement socket (18). On the surface of the engagement socket (14) side of the base (12), a slanting surface (12a) parallel with the protrusion-forming slanting surface (18b) is formed. From the "face" side of the base (20) of the male part (8), an engagement protrusion (23) extends diagonally downwards in the direction of the engagement socket (21). On both sides of the step (23c), a wall (23e) is provided. On the "face" side of the engagement socket (21) of the base (20), a slanting surface (20a) parallel with the protrusion-forming slanting surface (23b) is formed. The snap fastener has directionality in respect not only of disengagement but also of engagement.

A cam mechanism is used as a safety apparatus for a pressing apparatus that stops the pressing operation in an emergency by detecting the existence of a foreign object through a change in the operation of the press cylinder itself without adding a separate sensor. In the cam mechanism a cam follower (30) engages an endless guide groove (13) to impart a reciprocal movement to a follower link (31). The guide groove (13) comprises a restraining region (14) in which the cam follower (30) is guided in a restrained condition and a floating region (15) in which the cam follower (30) is guided in such a way that it can float freely in the direction that the follower link (31) reciprocates.
摘要:
A tape-mounted fastener is formed by introducing a tape (lla,llb) having at least one through hole (l3a,l3b) into a molding chamber (l8) having a shape corresponding to the desired fastener element (l0,20), feeding a synthetic resin into said molding chamber to enclose the edge of said through hole, and allowing or causing said resin to cure to form a fastener element integral with the tape. The edge of the through hole is restrained against deflection by the resin charged to the mold by projections (l9) provided in the molding chamber.

An engaging member for attaching an upholstery material to a cushion member, which has a positioning member at least one lengthwise terminal end. The positioning member places the starting end of loop engaging element portion in precise position in the groove of the cushion member. The engaging member is long and flexible and bends in conformity with the complicated shape of the curved groove. The method of producing an upholstered cushion molding using the engaging member improves the working efficiency.

A male-mounted tape (18) is composed of a plurality of synthetic resin male snaps (6) moulded and fastened onto a cloth tape at certain intervals in such a way that their engagement sides (61) and non-engagement sides (62), which are asymmetric to each other, are on the front side and the back side of the cloth tape respectively. A female tape (30) is composed of a plurality of synthetic resin female snaps (4) moulded and fastened onto a cloth tape at the same intervals as the male snaps in such a way that their engagement sides (41) and non-engagement sides (42), which are asymmetric to each other, are on the front side and the back side of the cloth tape respectively. The cloth tapes, on which the female and male snaps (4, 6) are formed and fastened, are not provided with holes for mounting the snaps. The engagement sides (61) and the non-engagement sides (62) of the male snaps (6) coexist on both the front side and the back side of the male tape, and the engagement sides (41) and the non-engagement sides (42) of the female snaps (4) coexist on both the front side and the back side of the female tape.
