A slide fastener stringer includes a row of helically coiled or zig-zag coupling elements of thermoplastic synthetic resin with a reinforcing core extending longitudinally therethrough. The coupling elements are secured to one surface of a stringer tape by sewing threads having portions running across and over upper legs of the coupling elements. Some of the coupling elements are cut off to provide an element-free space on the stringer tape. A terminal or endmost complete coupling element disposed adjacent to the element-free space has a free-ended connecting portion remote from a longitudinal edge of the stringer tape. To form an end of the slide fastener stringer, the free-ended connecting end portion of the terminal coupling element is fused to the stringer tape, and at the same time, the upper leg of the terminal coupling element is heated and pressed toward the stringer tape. A device for forming such a stringer end includes a stringer rest for supporting the end of the stringer, and a heating presser having a first surface for heating and pressing the free-ended connecting portion of the terminal coupling element against the stringer tape and a second surface for heating and pressing the upper leg of the terminal coupling element toward the stringer tape. The first surface projects beyond the second surface toward the stringer rest.

A fastening device for fastening a web-like material to a bag or like garment article comprises a connecting member, a link rotatable relative thereto, a cylindrical retaining member fitted rotatably over the connecting member and having a retaining bar, and a hook member having a J-shaped hook. A retaining pin member is adapted to interconnect the connecting member, the retaining member and the hook member and is resiliently releasable from the retaining member to permit the latter to rotate so that the retaining bar moves out of registration with the J-shaped hook.

A swivel hook comprises a hook body including a proximal part having an aperture formed at its upper end to define a pair of overhangs and a substantially J-shaped hook portion extending downward from the proximal part, an annular link having an connecting axle provided on one side thereof, the connecting axle having an enlarged head formed on its distal end, the enlarged head being inserted into the aperture into engagement with the overhangs; a locking member having a pair of opposing side walls defining therebetween a chamber; and biasing means mounted in the chamber. The proximal part of the hook body is pivotally mounted on the locking member within the chamber with the aperture closed by the opposing side walls and with the biasing means acting between the proximal part and the locking member for normally urging the locking member into engagement with the J-shaped hook portion.

Double lockable sliders comprise a pair of first and second sliders reciprocatively mounted on the slide fastener and disposed reversely to each other. When the second pull tab is turned flat against the first pull tab, the engaging projection provided at the distal end and on one surface of the second pull tab comes into the recess formed in one surface of the first pull tab, and the prong provided at one end of the latch member resiliently comes into locking engagement with the indentation formed in one side of the engaging projection. The double lockable sliders further include cam means for imparting to the engaging projection upward motion when the latch member is pulled away from the second slider longitudinally of the slide fastener.

A lock assembly for use on luggage, bags and the like has a mounting plate accommodating various lock operating parts including a latch, a hook member including a hook element and an ornamental cover fitted over the mounting plate. The latch is engageable resiliently with the hook element and lockable by a key. The ornamental cover is removably connected to the mounting plate and changeable from one to another with different types and designs.

A slide fastener lock assembly comprises a slider pull tab having an engaging pin and a lock having a locking lug releasably engageable therewith. The lock has a latch movable toward and away from the locking lug to lock and unlock the pull tab. A lock tumbler is rotatable by a key to releasably lock the latch with the engaging pin. The pull tab and the lock can be joined together simply by flipping the pull tab down with its aperture fitted over the locking lug.

In a method of making an ornament, a metal ornament body having an internal groove opening at one end to an end edge of the metal ornament body and at an opposite end to front and rear surfaces of the metal ornament body is held between two relatively movable mold members while the one end of the internal groove is connected to a gate of the mold members and the opposite end of the internal groove communicates with mold cavities in the mold members. Then, a melted synthetic resin material is injected into the mold cavities through the gate and the internal groove. The gate mark is not formed on the outside surface of an ornamental member molded of synthetic resin but left on the end edge of the metal ornament body. The gate mark thus formed is normally hidden from view and does not deteriorate the aesthetical appearance of the ornament.
