Abstract: A slider for a slide fastener, comprising: a slider body including an upper wing having a cutout; a board shaped cap resiliently received in the cutout and having a claw stopper hole; a claw stopper pivotally mounted in the cap and projecting through the upper wing and into the claw stopper hole; and a resilient claw stopper support mounted on a back surface of the cap and resiliently contacting the claw stopper.

Abstract: A slider for closing a coupling device, comprising: a slider body having a central guide for guiding male and female coupling elements of the coupling device, and a coupling guide channel; and a C-shape puller pivotally connected at its base to a front end of the slider body so as to be free in motion in a horizontal plane, there being a gap between the body and the puller.

Abstract: A lockable slide fastener slider includes an upper wing and a lower wing defining therebetween a guide channel for the passage of fastener coupling elements, a pull tab pivotably mounted on the upper wing and a locking member having a locking prong movable into and away from the guide channel. A resilient biasing arrangement is provided in operative relation to the pull tab for urging the latter to lie substantially flat against the upper wing.

Abstract: An automatic locking slider for slide fasteners comprises a slider body including a pair of upper and lower wings joined together, the upper wing having a pair of opposed lugs provided protuberantly on its upper surface; a locking member fitted between the lugs and pivotted at its middle to thereto, the locking member having at its lower end a locking prong; a spring member provided on the slider body for normally urging the front end of the locking member upwardly so as to bring the locking prong into locking disposition; and a pull tab for pulling up the rear end of the locking member so as to bring the locking prong out of locking disposition for reciprocation of the slider. The lugs are so bluged roundedly as to have their respective outer sides to extend substantially to and merge into the edge of the front end and as to substantially enclose a front half of the locking member on its opposed sides.

Abstract: An automatic lock slider for slide fastener comprises a slider body, a support lug integral with and disposed over the top surface of the slider body and a pull tab with which to move the slider. The slider includes a locking member in the form of a polygonal leaf spring having at one end a locking prong and at the other end a U-bent portion. A bulged portion is formed intermediate the prong and the U-bent portion and spaced a sufficient distance from the lower surface of the lug to permit lifting of the prong clear out of the passage of coupling element rows of a slide fastener.

Abstract: An automatic lock slider for slide fasteners comprises a slider body including an upper and a lower wing defining therebetween a guide channel for the passage of slide fastener elements, and a first and a second locking member associated with the upper and lower wings, respectively and rotatable in opposite directions into and out of engagement with each other through their respective link arms pivotally connected to the slider body, and a pair of pull tabs operatively associated with the locking members for manipulating the slider selectively from either of its sides.

Abstract: An automatic lock slider for slide fasteners comprises a slider body including an upper and a lower wing defining therebetween a guide channel for the passage of slide fastener coupling elements, a locking member for locking the slider against movement, a pull tab operatively associated with the locking member for manipulating the slider, a casing and a spring member interposed between the casing and the locking member and normally urging the latter in a direction to lock the slider. The casing has retaining lugs interiorly disposed for folding over the spring member to retain the latter in position stably but loosely to permit its resilient movement relative to the locking member.

Abstract: A slide fastener slider has an arch-shaped lug projecting from the top surface of an upper wing and terminating in a rear free end spaced from the top surface of the upper wing by a predetermined gap. A slide is slidably mounted in the upper wing and has a closure projection. The slide is movable between an open position in which the closure projection is spaced from the free end of the lug to open the gap for allowing the pintle of a pull tab to pass therethrough, and a closed position in which the closure projection is disposed adjacent to the free end of the lug to close the gap for preventing the pintle of the pull tab from passing therethrough. The slide is normally urged to its closed position by a spring mounted in the upper wing.

Abstract: A lockable slide fastener slider having a guide groove which allows a pair of rows of coupling elements to pass smoothly through a guide channel without entering an aperture communicating with the guide channel, even when the coupling elements are displaced toward the aperture. The guide groove is defined jointly by a bottom wall and a pair of oblique sidewalls diverging toward the guide channel, the bottom wall having a width substantially the same as that of the aperture. The peripheral wall bounding the aperture has an oblique end portion facing the guide channel and merging into the oblique sidewalls.

Abstract: A slider for a slide fastener comprises a slider body including a pair of upper and lower wings defining therebetween a Y-shaped guide channel, the lower wing having on its interior surface a ridge extending longitudinally of the guide channel for being locatable between a pair of stringer tapes of the slide fastener to slidably engage fastener elements of the slide fastener. The lower wing also has in the interior surface a pair of furrows disposed one on each side of the ridge and extending parallel thereto for allowing fastener-element-supporting edge portions of the tapes to be displaced into the furrows respectively. The furrows thus reduce frictional resistance between the stringers and the interior surfaces of the slider body. With such slider it is possible to correct a longitudinal divergence in interengagement between the opposed stringers without breakage or other damage to fastener-element-holding threads.

Abstract: A lockable slider includes a cylindrical plug rotatably mounted in a slider body and a locking member urged at its fore end by a spring member against a cam face of the cylindrical plug for pivotal movement about the one end in response to the rotation of the cylindrical plug, whereby a locking pawl disposed at the rear end of the locking member is brought into and out of locking engagement with a pair of coupling element rows of a slide fastener. The cam face includes a recessed central portion in which the fore end of the locking member is received with the slider in locked position, and a flat peripheral portion over which the fore end of the locking member lying across the recessed central portion is disposed with the slider in unlocked position. The cam face allows the cylindrical plug to be rotated bidirectionally for either locking or unlocking the slider.

Abstract: An automatically locking slider for slide fasteners has a locking member including a piece of resilient strip which is bent into a generally "3" or "E" shape having a U-shaped base extending around a transverse spindle of a pull tab, a locking prong extending from one end of the base, and an anchor extending from the other end of the base and terminating in a recessed end interlocked with a locking-member retaining-nose on a neck of a slider body. The base is normally urged against the spindle of the pull tab by the resilience of the strip. The recessed end of the anchor is normally urged against the nose by the resilience of the strip and is thereby prevented from coming out of interlocking engagement with the nose. Thus the locking member is held in position on the slider body solely by the resilience of the strip, requiring no bending or deformation of any part of the slider body that would make the slider defective from an aesthetic view.

Abstract: An automatically locking slider for slide fasteners has a locking member including a piece of resilient strip, preferably made of stainless steel, which is bent into a generally "3" shape having a U-shaped base extending around a transverse spindle of a pull tab, a locking prong extending from one end of the base, and an anchor extending from the other end of the base and terminating in a hook-shaped end hooked with a locking-member retaining nose on a slider's neck. The base is normally urged against the spindle of the pull tab by the resilience of the strip. The hook-shaped end of the anchor is normally urged against the nose by the resilience of the strip and is thereby prevented from being unhooked from the nose. Thus the locking member is held in position on a slider body solely by the resilience of the strip, requiring no bending or deforming of any part of the slider body that would make the slider defective from an aesthetic view.

Abstract: A slider with lock for a slide fastener is provided of which the built-in lock comprises (a) a cylindrical housing integrally fixed onto the upper wing of the slider body and provided with a sloped cam face on the inner surface thereof, (b) a rotor coaxially installed within the housing, capable of being turned with a key and capable of moving in the axial direction when turned by being guided along the sloped cam face on the inner surface of the housing, (c) a locking member with a lock claw directed toward the element rows of the slide fastener and engaged with the rotor so as to be moved in the axial direction of the rotor by rotating by being guided along the sloped cam face, (d) a spring interposed between the rotor and the locking member so that the locking member is always urged toward the element rows, and (e) a cover. With this structure of the lock, the element rows are locked by being jammed with the lock claw which is pressed firmly by the compressive resilience of the spring.

Abstract: Disclosed is a lockable slider for a slide fastener in which but a single spring is provided on the fore thereof that has double functions to urge a cylindrical member upwardly for enabling the rotation thereof by a separate key and to simultaneously bias the fore end of a locking lever pivotally supported at its middle upwardly to pivot it in such a way to intrude a locking pawl formed at the rear end thereof into engagement with fastener elements, thus locking the slider relative thereto. The lockable slider thus permits to be the more compact in its rear, rendered itself the more attractive in appearance compared with the prior art slider equipped with two springs, one on the fore and the other on the rear thereof.

Abstract: A slider for a concealed slide fastener comprises a body including a flared front end and a contracted rear end, and having a bottom wall, a pair of side flanges formed on the bottom wall, and a pair of inturned lips extending from the side flanges. A element guide island is formed centrally on the bottom wall near the flared front end and cooperates with the side flanges in providing a substantially Y-shaped guide channel for the passage therethrough of a pair of rows of interlocking fastener elements. A support lug is provided on the island, and a pull tab is pivotally supported on the lug. The pull tab is rectangular and has at one end an aperture, bifurcations bounding the aperture, and a pintle connecting the bifurcations together and passing through a hole formed in the lug. The bifurcations have extensions held in engagement with the sides of said support lug.
