A pair of second guide element passages are formed in a space among an upper plate, a lower plate, a pair of outer wall portions and a pair of inner wall portions to guide a pair of separated element rows into a first element guide passage of a slider. The upper plate, the lower plate and a connection post have a concave surface, which is recessed in a disengaging direction of the slider, in a surface facing toward an engaging direction of the slider. The pair of second guide element passages are configured so that tip ends of the pair of inner wall portions in the engaging direction are located at the same positions as or at a side of the engaging direction relative to tip ends of the pair of outer wall portions in the engaging direction.

Abstract: Embodiments herein provide modified slider bodies with one or more features such as an elongated spring cap, a protrusion on the bottom plate and/or plate coupler of the slider body, and/or vertically offset side rails. These features may minimize introduction of loose fabric, such as the lining of a lined garment, into the tape slot of the slider body, thereby help reduce jamming of the slider body during operation of the slide fastener.

Abstract: The invention provides a fastener stringer for a hidden slide fastener. Each of the fastener tapes includes a main tape body, a folded tape portion which is folded into a U-shape, and an element attaching portion. The folded tape portion includes at least two multiple-weave portions in which warp yarn forms a multiple-weave structure, and a single-weave portion arranged at least at one location of an intermediate portion of the folded tape portion. According to this, it is possible to enhance rigidity of the folded tape portion in a lateral direction of a tape, and to prevent a position of the warp yarn from being misaligned at the multiple-weave portion. Therefore, hiding performance of the hidden slide fastener can be enhanced.

Abstract: The CTF Flip-N-Zip slider enables the purchasers of a zipper with the CTF Flip-N-Zip slider installed to disconnect at least one side of a zipped zipper and return it to the starting position. Current fixed sliders are very hard to fix if a foreign object jams the zipper or if the zipper opens behind the slider. CTF Flip-N-Zip slider requires only that the owner disengage the lock and remove either the top or bottom plates or half plate depending on the design. This is shown in the drawings for a releasable latch pin of the slider. The owner would then return the zipper to the starting position and reattach and lock the slider and start over using the same slider. Other designs currently in consideration are push button releases, hinged plates with hidden lever, draw activated releases, etc. Sliders will be made to fit all available zippers and zipper materials.

Abstract: An integral zipper slide and guard. The integral slide and guard is formed as a single unit, thus alleviating previous problems of attachment of zipper guards to zipper slides. Moreover, the unitary structure of the zipper slide and guard permits a one-step molding operation, thus providing inexpensive manufacture.

Abstract: A concealed type slide fastener comprises two fastener tapes having their opposed edges folded thereon; two rows of fastener elements mounted on the folded edges; a top end stop mounted a fastener element row; and a slider movable along the element rows. The slider 1 has a slider body and a guidepost mounted on the body to define therewith a guide channel through which the element rows run. The guidepost has a sliding surface formed on each side and an overhanging element-guiding portion extending from the upper end of the sliding surface. The concealed type slide fastener further includes means for preventing contact between the element-guiding portion and a corner of the top end stop which faces the element-guiding portion.

Abstract: A zipper guard is formed as a one-piece homogeneous plastic molding. Resilient hooks or latches are formed on the zipper guard to provide a simple snap-fit interconnection between lugs on a zipper slide and two pairs of engagement legs on the zipper guard. The zipper guard may be retrofitted to existing zipper slides or fitted to new zipper slides.

Abstract: A zipper of the type having two tapes with interconnecting teeth, a slide having a front and rear and including a divider to separate and mesh the teeth in cooperation with a pull tab attached to the slide, includes spaced wing segments formed on the slide in proximity to the front of the slide. The spaced wing segments present a profile at the front or leading edge of the slide, in which the profile takes the form of a plow. The plow-like profile is formed as a beveled surface at the leading edge, and is thus adapted to force extraneous material such as threads, fabric, and the like, away from engagement with the interconnecting teeth when the zipper is zipped to the zipped-up condition. The trailing edge, or rear, of the slide may similarly be beveled to exclude unwanted fabric when the zipper is unzipped.

Abstract: A zipper including a pair of rows of teeth, a catch for joining/unjoining the two rows of teeth as the catch is moved relative to the two rows of teeth; a pair of flaps disposed underneath the two rows of teeth, respectively, such that as the catch moves relative to the two rows of teeth to join the two rows of teeth together, the pair of flaps overlap each other, thereby preventing extraneous material from being entangled in the catch and the two rows of teeth.

Abstract: An anti-binding slide for a slide fastener is provided and consists of a side wing segment at each corner of the slide to make a spreading action for reducing the binding of material to be zipped together and separated. The retainer bar is elongated and has an elongated slot therein so that the pull tab will put pressure at either extreme end of the slide when pulling the slide.

Abstract: A slide fastener slider includes a pair of parallel spaced wings each having a generally W-shaped front edge extending between a pair of flanges extending along the opposite lateral edges of the wing across a neck interconnecting the wings to define therebetween a substantially Y-shaped guide channel. The front edge has a pair of outer portions respectively disposed adjacent to the flanges and projecting forwardly beyond a pair of planes extending respectively between a front end of the neck and respective front ends of the flanges. Each of the wings has a pair of sloped interior guide surfaces extending respectively along the outer portions of the front edge and facing forwardly of a slider body of the slider.
