Field of the Invention The present invention relates to slide fasteners and, more particularly, to an improved slider for a filamentary fastener.
  • conventional slide fasteners typically include a pair of elongated carrier tapes upon which are attached a series of individual coupling elements along one of the longitudinal edges of each tape. Such elements have long been made of metal and are crimped or otherwise secured along a woven bead on the edge of each tape to form the fastener chain.
  • a slider defining a V-shaped channel is slidably disposed on the chain and has a pull tab enabling one to selectively interengage or disengage the chain halves by upward or downward movement, respectively, of the slider. 7
  • a slider for a slide fastener includes a main body member having a. pair of spaced, parallel wing members, a pair of flanges extending respectively from opposite lateral edges of each wingmember toward each other to define a Y-shaped channel for slidably receiving the slide fastener, and each of the. flanges being chamfered along at least a portion of a longitudinal inner edge thereof whereby the channel conforms to the configuration of a laterally loaded fastener.
  • This invention has a further object in the construction of a fastener slider having fewer sharp edges and conforming to the configuration of a laterally loaded fastener chain.
  • Another object of the present invention is to reduce slider binding and excessive stitching thread wear while enhancing the smoothness of operation of a completed fastener.
  • Some of the advantages of the present invention reside in its freedom from binding, its smoothness in operation and its ability to provide improved operation without cutting, fraying or otherwise damaging or disrupting the fastener stitching threads.
  • FIG. 1 is a fragmentary plan view of a filamentary slide fastener having an improved slider according to the present invention
  • FIG. 2 is an enlarged sectional view of the slider of FIG. 1;
  • FIG. 3 is a sectional view of a complete slider taken along line 3-3 of FIG. 2;
  • FIG. 4 is a-sectional view similar to FIG. 3 taken along line 4--4 of FIG, 2;
  • FIG. 5 is a sectional view similar to FIG. 3 taken along line 55 of FIG. 2;
  • FIG. 6 is a sectional view ofthe fastener chain of FIG. 1 in an unloadedor relaxed state
  • FIG. 7 is a sectional view similar to FIG. 6 with the chain in a laterally loaded condition and showing the cooperation between the stitching threads and the slider according to the present invention.
  • the present invention is embodied in a filamentary slide fastener indicated generally at 10 in FIG. 1 including a pair of interengagable filamentary stringers 12 and 14 mounted on carrier tapes 16 and 18, respectively.
  • the filamentary stringers l2 and 14 are each disposed along a longitudinal edge of a respective one of the carrier tapes at a woven, elongated bead 20-22 formed thereon and are held securely in place by any suitable means such as stitching threads 24 and 26, respectively, (FIG. 6).
  • a pull tab 28 is connected to a slider, indicated generally at 30, which is disposed on tapes l6 and 18 to facilitate selective opening and closing of the slide fastener 10.
  • Slider 30 has a pair of parallel superposed wing members 3.2,and 34 which are joined at their upper ends (as visualized in FIGS. 1 and 2) by a generally rectangular spacing member or neck 36 having its longer dimension aligned longitudinally of the carrier tapes 16 and 18.
  • wing members 32 and 34 extend from neck or spacing member 36 in cantileverfashion.
  • Spacing member 36 has an exteriorend 38 which may be formed flush with the upper edges of wings 32 and 34 and an interior end 40 which is tapered in the plane of tapes 16 and 18 to form an apex 42.
  • End 40 of spacing member 36 also may be tapered in a plane normal to the plane of tapes l6 and 18 to form a V-shaped edge (not shown) with the shaped edge and apex 42 joined by a smooth continuous surface which acts to separate the interengaged stringers l2 and 14 as the slider is moved downwardly along the fastener tapes.
  • Flanges 44 and 46 forming a first pair of opposing flanges, extend from one lateral edge of each wing member 32 and 34, respectively, toward each either; similarly, flanges 48 and 50, forming a second pair of opposing flanges, extend from an opposite lateral edge of each wing member 32 and 34, respectively, toward each other.
  • Each of flanges 44, 46, 48 and 50 has a longitudinal portion 52-54-56-58 (shown in transverse section in FIG. parallel to the longitudinal centerline of the slider 30 and an outwardly divergent portion 60-62-64-66 (shown in transverse section in FIG. 3) contiguously joined with the longitudinal portion to form an elbow 68-70-72-74 (shown in transverse section in FIG. 4).
  • each of the longitudinal and outwardly divergent portions is substantially straight such that each of the flanges 44, 46, 48 and 50 form an obtuse angle in the plane of the carrier tapes 16 and 18.
  • Angulated flanges 44, 46, 48 and 50, wing members 32 and 34, and tapered spacing member 36 cooperate to define a generally V-shaped channel for receiving the filamentary stringers 12 and 14 of the slide fastener 10.
  • each of the flanges 44, 46, 48 and 50 is disposed such that the elbow member thereof is adjacent the throat of the V-shaped channel and has a chamfered inner edge 76-78-80-82 to accommodate the configuration assumed by the fastener under a lateral load.
  • Chamfered edges 76, 78, 80 and 82 are each in the form of a canted planar surface having a generally triangular periphery best seen in FIG. 2.
  • the canted planar surfaces are obliquely disposed with respect to the longitudinal centerline of the slider 30 and to the parallel planes of wing members 32 and 34, with the angle of the canted surfaces less than the angle of the divergent portions of the flanges referenced to the slider longitudinal centerline.
  • planar chamfered edges 76, 78, 80 and 82 of flanges 44, 46, 48 and 50 respectively specifically conform to the configuration of the synthetic fastener chain including tapes l6 and 18, filamentary stringers l2 and 14 and stitching threads 24 and 26 especially when the chain is subjected to lateral tension as normally experienced during closing of the fastener.
  • FIGS. 6 and 7. a filamentary slide fastener is shown in section with the stitching threads illustrated in an unloaded or relaxed state. While the overall cross-sectional configuration of the stitching threads and the filamentary stringers is generally rectangular, it can be appreciated from a comparison with the diagrammatic view of FIG.
  • the present construction reduces the operational effort required to open and close the fastener and assures smooth slider operation free from binding and stitching thread wear.
  • the chamfered flange construction of the slider according to the present invention acts in a somewhat cam-like manner, especially during movement of the slider upward or in a closing direction, for enhancing the ability of the slider to draw the separated fastener chain halves together at the throat of the V- shaped channel.
  • the fastener halves are forced together by the divergent portions of the slider flanges for intercoupling at the throat of the channel.
  • the chamfered flange edges or canted'planar surfaces 76, 78, and 82 enable the fastener chain to pass through the channel without binding, as noted above, and at the same time act on the filamentary stringers 12 and 14 in a manner to promote the desired coupling thereof. Consequently, the slider 30 of the present invention does not tend to distort the filamentary stringers nor does it tend to pinch or capture individual stringer coupling elements as was often the case in the past.
  • the present invention provides a slider for a filamentary fastener having overall improved operational smoothness and freedom from binding, fraying and stitching thread wear. Furthermore, the slider of this invention conforms to the distorted configuration as sumed by fastener chain made of synthetic materials and having modern filamentary coupling elements seron to the carrier tapes. As such, the present invention represents a substantial departure from the prior art in the specific inclusion ofthe characteristics of filamentary chain both at rest and under loading as slider design parameters.
  • a slider for a slide fastener having filamentary coupling elements attached to a pair of carrier tapes by stitching threads comprising a main body having a pair of spaced, parallel wing members and a longitudinal center line,
  • each of said flanges having a first portion substantially parallel to said center line
  • each of said flanges having a second portion diverging outwardly from said center line
  • each of said flanges having an elbow joining said first portion and said second portion
  • each of said canted planar surfaces forming a chamfer of said elbow and defining a plane obliquely angled with respect to said center line such that said canted planar surfaces permit slider tions of said flanges is angled away from said center line at an angle greater than that made by said canted planar surface with respect to said center line.
