For semipermanently locking a slider in a fully closed position on interlockable rows of fastener elements, a locking pawl is formed integral with one of the wings of the slider for engagement with the fastener elements received therein. The locking pawl may either automatically lock the slider against movement in its closed position or be pincered into the slider at the end of its fastener closing movement.

A continuous coupling element is fashioned from an elongated synthetic resin filament or the like, which filament is bent to a zigzag or meandering configuration to provide a series of U-shaped transverse portions each having a coupling head and a pair of legs extending rearwardly therefrom. Parts of the legs of each U-shaped portion are deformed to provide tape gripping portions, respectively, which include laterally expanded, flat surfaces arranged in opposed relationship to each other. The continuous coupling element is to be anchored to a stringer tape as by bonding or fusing the tape gripping portions to the opposite surfaces of the tape.

In a slide fastener stringer having a row of discrete fastener elements arranged along one longitudinal edge thereof and each comprising a coupling head at its front end and a pair of parallel spaced legs extending rearwardly from the coupling head, the rear end portions of the legs of each fastener element are flattened into plate-like shape, with steps formed between these flattened rear end portions of the respective legs and their remaining portions. The flattened rear end portions of the legs of each fastener element are embedded into the stringer tape from both surfaces thereof, to such a degree that the outer surfaces of the flattened rear end portions are flush with the corresponding surfaces of the stringer tape, thereby providing slideways for the marginal guide flanges of a slider traveling along the fastener elements.

An automatic slider lock mechanism releasable by a pull tab, comprising a locking leaf spring arranged under the island separator on the front end of the slider body, and an actuating lever received in an aperture formed through the separator. The actuating lever has a pair of shoulders at its bottom end which are urged by the leaf spring into engaging contact with the bottom edges of the separator. Upon exertion of a pull on the pull tab coupled to the top end of the actuating lever, the latter is pivoted within the aperture to cause retraction of a locking pawl at one end of the leaf spring away from the guide channel in the slider body.
摘要:
A slide fastener having an emergency opening zone at its intermediate point from which the fastener can be forced open in an emergency without pulling a slider along interengaged rows of fastener elements. To make this slide fastener reusable, a slider escape mechanism is arranged at its top end for causing the slider to ride on only one of the stringers by releasing the other stringer therefrom after the fastener has been forced open. Arranged at the bottom end of the fastener is a connect-disconnect terminal mechanism which may take the form of a box-and-pin separable coupling, such that the fastener stringer can be reconnected to permit normal slider movement after having been completely separated from each other.
摘要:
A sliding clasp fastener including interlocking elements of a continued meander structure which are disposed astride a longitudinal tape edge at their leg and connecting portions. The leg and connecting portions are deformed to provide flattened, enlarged undersurfaces adapted to be held in intimate contact with the tape. The connecting portions are also deformed to produce recesses for receiving therein side flanges of a slider.
摘要:
A support strip preferably made of resilient material and adapted to permit a number of sliders to be removably mounted astraddle one of the longitudinal edges thereof for the sake of convenience in storage. A longitudinal row of spaced apart apertures is formed through the support strip substantially the full length thereof, such that when the sliders are later required for the assemblage of complete slide fasteners, the sliders can be fed to a desired assemblying machine with the support strip running over a sprocket having its teeth engaged in the successive apertures formed therein. A reciprocable push rod may be employed for removal of the successive sliders from the support strip.
摘要:
A chair of a relatively simple construction is disclosed, which essentially comprises a seat and a back-rest interconnected therewith by a sliding clasp fastener. The back-rest in particular is clad with a cover attached with one of a pair of fastener stringers, the other stringer being attached to a marginal edge of the seat or its cover.

There is disclosed an adapter and anchoring means combination for securing floor coverings into position on floors or the like. The adapter comprises a longitudinal strip for attachment to a reverse surface of the covering or carpet and a locking projection formed integrally with and extending along a longitudinal edge of the strip. The anchoring means is in the form of plinth or baseboard and has an elongate channel and a slit communicating coextensively with the channel. The locking projection protrudes from an edge of the carpet and is retained in locked relation to the channel when the adapter is attached to the carpet.
摘要:
A safety head-rest for an automobile seat or the like is provided with a sliding clasp fastener secured to marginal edges of an opening defined by two substantially identical halves constituting a head-rest body, one of said halves having an aperture for receiving a support post adapted to connect the head-rest to the seat.
