Abstract: There is provided a slide fastener slider. A front mounting portion and a rear mounting portion are respectively provided with receiving grooves for receiving a lock member. The receiving grooves have right and left side walls. Protrusions are respectively provided on upper end edges of the side walls of the front mounting portion. When the upper end portions of the side walls of the front mounting portion are inclined in a direction of approaching each other, the protrusions approach each other, and the protrusions cover the lock member more largely relative to portions of the side walls other than the protrusions.

Abstract: A cover fastening clip includes a locking section that locks with an end member to be locked that is provided on the edge of a cover, and a hook that engages with a wire disposed in a groove of a cushion material. The hook is provided with an extended section that extends down from the locking section and a claw-shaped section, and the locking section is provided with a guide piece. The guide piece extends down along the extended section of the hook, bends at a midway bending section, and extends toward the distal end of the claw-shaped section. A wire insertion opening that has a prescribed gap and into which the wire is inserted is formed by the distal end of the guide piece reaching a location that faces the distal end of the claw-shaped section.

Abstract: A component for fasteners, including a molded component formed of a polyamide resin composition including reinforcing fiber, wherein a dyed layer being dyed inward from a surface of the molded component is disposed, and the thickness of the dyed layer is 30 to 100 ?m.

Abstract: Systems and methods for joining two or more pieces of hook fastener tape. In some embodiments, the two or more pieces of tape are spliced together using ultrasonic welding. At least one of the splicing components used to splice the tapes together may be configured so that the component influences the profile of a connecting portion along which the two tapes are welded together. In some cases, at least one of the splicing components may be configured to minimize deformation of the tapes as they are welded together.

Abstract: A buckle with an enhanced efficiency in removing a foreign substance is provided. The buckle includes: a plug; and a socket provided with an insertion opening into which the plug is to be inserted. The socket includes: a pair of front pieces disposed side by side in a width direction intersecting with an insertion direction of the plug; a back piece disposed to face each of the front pieces; and a bottom piece that connects each of the front pieces and the back piece. A slit defined between the pair of front pieces extends in the insertion direction from the insertion opening across the bottom piece and the front pieces of the socket. Due to the presence of the slit, a cross section of the socket intersecting with the insertion direction is in a C-shape.

Abstract: These fastener elements have: an element main body portion having a coupling head portion; and first and second projections that project in a tape surface/rear-surface direction from the element main body portion. The first and second projections have a top surface, peripheral side surfaces standing upright from the element main body portion, and at least one sloped surface between the top surface and the peripheral side surfaces that has a different angle of inclination from the top surface and the peripheral side surfaces. As a result, the fastener elements appear long and narrow in the element length direction and have an external appearance close to that of a metal element. Furthermore, a stop claw portion is less likely to catch on the fastener elements when starting the sliding operation of a slider.

Abstract: A skin material fastening structure for removably fastening an edge of a first skin material covering a part of molded foam and an edge of a second skin material covering another part of the molded foam in a fastening groove formed in the molded foam. The fastening groove includes first and second sides facing each other, and a bottom extending between lower ends of the first and second sides. A hook and loop fastener is fixed on the first and second sides. Each of the edges of the first and second skin materials has loops capable of engaging with the hooks.

Abstract: A surface fastener member includes left and right longitudinal protective wall sections and front and rear lateral protective wall sections. Each of the lateral protective wall sections includes an outer first lateral wall section and an inner second lateral wall section. The first lateral wall section is continuously placed between the left and right longitudinal protective wall sections at a predetermined height. The second lateral wall section includes a plurality of divided lateral wall bodies which are intermittently placed along a width direction, and a plurality of second engagement elements. The distance is set smaller than a mounting pitch of the first engagement elements in the longitudinal direction of the surface fastener member. According to this, when the molded surface fastener is integrally molded on a cushion body, it is possible to prevent resin material from entering an engagement element region of the surface fastener member.

Abstract: There is provided a stop for a slide fastener. A top plate and a bottom plate are linked with one another at a transversely intermediate position by an integral connecting post. The lower side of the top plate is substantially flat. The bottom plate slopes away from the connecting post to form two leg members provided with a respective end flange pointing towards the top plate, the leg members being adapted to cooperate in use with the top plate to retain fastener tapes therebetween.

Abstract: A rivet is applied from a rear surface of a fabric for mounting a burr on a front surface of the fabric. The rivet comprises a disk-shaped base, and a shank projecting from and concentrically with the base. The base includes an annular recess around a proximal end of the shank, which is depressed in a direction opposite to the shank-projecting direction, and a flange radially outward from the recess. The flange includes a plurality of bumps which are raised from an upper surface in the shank-projecting direction. The bumps may be provided on the upper surface of the flange at equal circumferential intervals, and a top of each of the bumps may be a curved face. The recess may have an inclined outer surface adjacent to the flange. Each of the bumps may have an inclined inner surface extending continuously from the inclined outer surface of the recess.

Abstract: There is provided an opener of a slide fastener. A separable pin accommodation part of a retainer has upper and lower walls facing each other, a pair of wall parts protruding from the upper and lower walls in a direction of narrowing an interval therebetween, and a bottom wall configured to join the upper and lower walls at the rear of the pair of wall parts. The pair of wall parts extend toward the bottom wall from a rear side relative to front ends of the upper and lower walls. A pair of restriction parts are configured to collide with each other so as to restrict a position of a rearmost end of a separable pin to be inserted into a separable pin hole to a position between the bottom wall and front ends of the pair of wall parts are separately provided for the retainer and the separable pin.

Abstract: There is provided a slider cover for a slide fastener. An upper member and a lower member are spaced apart from each other in an upward and downward direction and arranged in parallel to each other. A connecting post connects the upper member with the lower member. The upper member includes a receiving portion configured to receive at least a part of an upper blade of a slider.

Abstract: There is provided a slider for a slide fastener. The slider includes a slider body, an elastic body and a pull tab. The pull tab includes a shaft, a pull tab main body and a cam. The cam is configured to elastically deform the elastic body when the pull tab is laid down. The slider body includes an upper blade and a pair of pull tab attaching posts. The upper blade includes a recess portion and a crimping portion. The recess portion includes a pair of lateral recess portions and a center recess portion. The crimping portion protrudes from at least one of the lateral recess portions at a protruding location located at a center side relative to both front and rear ends of the center recess portion.
