Definitions

  • An essentially plate-shaped slider has two wings with confronting camming edges separated by a gap for the passage of coupling formations of a pair of mating fastener halves, each of these halves forming a pair of interconnected parallel flanges carrying the corresponding coupling formations and bracketing a respective wing between them.
  • connection between the flanges may extend between the confronting camming edges or around the opposite, outer edges of the two wings; in the first instance the wings are interconnected by at least one transverse end strip separated from them by slots giving passage to one of the flanges of each half, whereas in the latter instance they are interconnected by a central web toward which the split coupling formations project from opposite sides.
  • the leading ends of the wings as seen in the direction of closure motion, may diverge in opposite directions from the common plane of their trailing ends whereby the coupling formations of the two fastener halves are moved perpendicularly to that plane for interlinking or disengagement.
  • My present invention relates to a slide fastener and, more particularly, to the construction of a slider and associated fastener halves whose complementary coupling formations are interengageable and disengageable by reciprocation of that slider as is well known per BAACKGROUND OF THE INVENTION
  • Conventional sliders generally comprise a pair of substantially parallel plates, respectively overand underlying each fastener half, which are interconnected by a central wedge piece designed to open the fastener; the outer edges of these plates are provided with confronting projections for closing the fastener by exerting a camming action upon its two elastically deformable halves.
  • Such a slider is therefore essentially a threedimensional body which is relatively bulky and has a rather limited compressive strength perpendicular to its plates. Moreover, since the two fastener halves are completely bracketedby these plates, restrictions are imposed upon their mode of attachment to associated stringer tapes through which these halves are conventionally connected with parts of garments or the like that are to be joined together by the fastener.
  • the general object of my invention is to provide an improved slider-and-fastener combination avoiding the aforest'ated disadvantages.
  • a more particular object is to provide a simplified slider, adapted to be manufactured for example by a single stamping operation, for use with an otherwise more or less conventional fastener, e.g., one whose halves consist of meandering monofilaments such as nylon threads.
  • a slider embodying my invention is essentially plateshaped and has a pair of wings with confronting camming edges separated by a gap for the passage of the coupling formations of the associated fastener halves, each of these halves forming a pair of interconnected, substantially parallel flanges carrying the corresponding coupling formations and bracketing a respective wing between them.
  • the wings are interconnected at the leading end of the slider (as seen in the direction of closure motion), or at each end fastener half to be divided into a series of separate links held together by a common stringer tape.
  • the leading ends of the two wings may diverge in opposite directions from the common plane of their trailing ends so that the coupling formations of the fastener halves are guided into and out of engagement with each other by a motion perpendicular to that plane.
  • the coupling formations may be designed as continuous beads rather than as longitudinally separated heads of the type commonly used in slide fasteners.
  • FIG. I is a plan view of a significant part of a slide fastener embodying my invention.
  • FIG. 2 is a longitudinal sectional view taken on the line II II of FIG. 1;
  • FIG. 2A is a view similar to FIG. 2; showing a modification
  • FIG. 3 is a cross-sectional view taken on the line III III of FIG. 1;
  • FIG. 4 is a plan view of a slider forming part of the embodiment of FIGS. 1 3;
  • FIG. 5 is a view similar to FIG. 1, illustrating another embodiment
  • FIG. 6 is a longitudinal sectional view taken on the line VI VI of FIG. 5;
  • FIG. 7 is a cross-sectional view taken on the line VII VII of FIG. 5;
  • FIG. 8 is a plan view, similar to FIG. 4, of a slider used in the embodiment of FIGS, 5 7;
  • FIGS. 9 and 10 are cross-sectional views respectively taken on lines IX IX and X X of FIG. 5;
  • FIG. 11 is a plan view, similar to FIGS. 1 and 5, of a further embodiment
  • FIG. 12 is a cross-sectional view taken on the line XII XII of FIG. 11;
  • FIGS. 13 17 are cross-sectional views generally similar to FIG. 7, illustrating various combinations of fasthereof, by bridge means in the form of a transverse strip which is separated from these wings by slots giving passage to one of the flangesof each fastener half; if the slider is flat, the two fastener halves are bent out of its plane on passing through these slots, yet the slider may also be curved to preserve the planar position of these halves.
  • the flanges are interconnected at the outer edges of the slider wings which in turn are joined 'to each other by a central web; this requires a foreshortening of the coupling formations or, preferably, a splitting thereof into segments approaching that web from opposite sides, i.e., from the front and the back of the slider.
  • Such an inverted arrangement also allows each tener halves and sliders according to my invention;
  • FIG. 18 is a plan view similar to FIGS. 1, 5 and 11, showing still another embodiment.
  • FIG. 19 is a cross-sectional view taken on the line XIX XIX of FIG. 18.
  • FIGS. 1 4 The embodiment of my invention shown in FIGS. 1 4 comprises two elastically deformable fastener halves l with coupling formations 6 in the shape of projecting heads longitudinally spaced along their confronting edges.
  • Each fastener half includes two parallel flanges 3 and 4 defining, together with a connecting part2 carrying the coupling heads 6, a generally J- shaped profile as best seen in FIG. 3.
  • the shorter flange 3 overlies the front surface 12 of a flat, plate-shaped slider 5 whose back surface 13 rests against the longer flange 4; this slider is formed with two wings 10 each bracketed by the flanges 3, 4 of a respective fastener half 1.
  • the fastener halves may be integrally molded from theremoplastic material, e.g., polyamide; parts 2 4 could also be woven from preferably theremoplastic fibershaving the necessary elasticity and stiffness, with the coupling heads 6 secured thereto by any suitable means.
  • polyamide polyamide
  • parts 2 4 could also be woven from preferably theremoplastic fibershaving the necessary elasticity and stiffness, with the coupling heads 6 secured thereto by any suitable means.
  • the wings 10 of slider are separated by a longitudinally extending gap 9 which is relatively narrow at the trailing ends 10a of these wings (as viewed in the direction of the closing stroke of the slider indicated by an arrow A) and has a diverging portion in the region of their leading ends 10b.
  • the wings are interconnected by an end strip 14 spaced from their leading ends 10b by slots 11 which communicate with the gap 9 and are traversed by the shorter forward flanges 3 of fastener halves l as best seen in FIG. 2.
  • End strip 14 is integral with a wedge piece 14a which projects into the widening gap portion between the leading ends 10b of wings 10 and serves to disengage the interlinked coupling heads 6 of the two fastener halves during the opening stroke of the slider, i.e., upon its movement opposite the direction of arrow A.
  • a tab 16 which facilitates manual operation of the slider and may also be manipulated to lock the slider in position as is well known per se, is hinged to the end strip 14 which bridges the wings 10.
  • FIG. 2A I have shown a slider 5' which, in contradistinction to the slider 5 of FIGS. 1 4, has its end strip 14 bent out of the plane of wings 10 to an extent sufficient to let the front flange 3 of each fastener half 1 pass straight through its slot 11' so that the two fastener halves can retain their planar positions during reciprocation of the slider.
  • a wedge piece 14a depends from the strip 14 into the plane of the wings.
  • the slider 5 could also be slightly curved abouts its longitudinal centerline, e.g., with its outer edges bent up as viewed in FIG. 3.
  • FIGS. 5 10 I have provided a slider 105 which, as best seen in FIG. 8, differs from slider 5 mainly by the fact that its wings 1 10 are bridged by two end strips 114' and 114" spaced from their leading and trailing ends by respective slots 111' and 111". These end strips are connected with the slider wings through bent legs 115', 115" so as to be raised from the plane of the wings 110, substantially in the manner of strip 14' (FIG. 2A), for the purpose of allowing the flange 103 of a fastener half 101 to remain essentially straight during slider reciprocation.
  • the strips 114' and 114 are centrally interconnected by a handle bar 114b offset from the plane of the wings; a separating wedge piece 114a depends from leading strip 114 in a manner similar to that of wedge piece 14a in FIG. 2A.
  • FIG. 6 alsoshows a pair of end stops limiting the slider stroke, namely a top stop 117 and a bottom stop 117".
  • the top stop 117 (which is individual to each fastener half 101) is formed by fusing the thermoplastic flanges 103 and 104 to each other.
  • the flanges of both fastener halves are fused to form the common bottom stop 117".
  • the coupling heads 6, 106 of fastener halves 1, 101 are shown provided with apertures 6a, 106a and projections 6b, l06b fitting into the apertures of the mating heads of the other fastener halves. It will be understood, however, that the shape of these heads may be varied and that different types of fasteners, such as meandering monofilamentary coils as illustrated in FIGS. 13 e '15, could also be used in the aforedescribed embodiments.
  • FIGS. 11 and I2 show a slider 205 which is generally similar to slider 5 of FIG. 4, except for the omission of wedge piece 14a and the fact that the leading ends of its wings 210 are bent in opposite directions out of the plane of their trailing ends, causing the connecting strip 214 to assume a generally S-shaped curvature.
  • the two fastener halves 201 invertedly engaged by these wings 210, which are again bracketed by flanges 203 and 204 thereof, are thus spread apart in a transverse plane (see FIG. 12) between the slider 205 and the nonillustrated top stops.
  • the fastener halves are moved toward each other at right angles to the basic plane of the slider (i.e., the plane of its trailing ends) so that their coupling formations 206 may be different from those shown at 6 and 106 inpreceding Figures.
  • these formations 206 may be continuous longitudinal beads of a profile as shown at 6E in FIG. 17 more fully described hereinafter.
  • FIGS. 13 14 I have illustrated various possibilities for attaching the two fastener halves to stringer tapes or other pieces of fabric to be joined to each other by the fastener.
  • two fastener halves 1A, bracketing a flat slider 5A of the type shown in FIGS. 1 4, are stitched at 22A to respective tapes 8A;
  • the fastener halves 1A are meandering monofilaments (e.g., of nylon) whose bight portions carry coupling heads 6A and which are further provided with ribs 23A for reducing the friction between their flange-forming sections and the slider wings bracketed thereby.
  • each fastener half 1B is traversed by a heavy filler cord 7B received in the gap between the two wings of a slider 58 which is generally similar to slider of FIGS. 5 8.
  • These filler cords are traversed by stitching 22B securing them to the meandering coils of the fastener halves which in this instance are shown provided with bosses 23B facilitating the relative displacement of the slider; the associated coupling heads have been designated 68.
  • the cords 7B may in turn be stitched onto respective pieces of sheet material, e.g., as illustrated in FIG.
  • each fastener half 1D comprises an extruded U-shaped profile 19D with flanges 3D, 4D and a bight portion 2D carrying the coupling heads 6D, this bight portion being recessed at 24D to receive stitching 22D which in the present instance is shown to pass through both layers of two pieces of folded fabric 8D.
  • FIG. 17 depicts fastener halves 1B in the form of extruded profiles, generally similar to those shown at 19D in FIG..16, which are integral with the above-discussed longitudinal beads 6E and are also made in one piece with respective strips 19E adapted to be stitched or otherwise secured to nonillustrated pieces of fabric or other sheet material.
  • FIGS. 13 17 are only given by way of example and may be modified, for example, by the interchange of compatible features thereof.
  • FIGS. 18 and 19 l have illustrated an embodiment of my invention wherein two fastener halves 301 coact with a slider 305 whose wings 310, separated by a gap 309, comprise each a multiplicity of links 320 clamped onto respective stringer tapes 308, each link forming a pair of flange sections 303, 304 which bracket a respective wing 310 of slider 305 and are interconnected by a leg 302 externally of the slider, i.'e., along the outer edge of its wing.
  • the two wings 310 are joined together by a central web 321 whose thickness is substantially less than that of the wings and which partly occupies the intervening gap 309.
  • Each link 320 (only a few of which have been illustrated in FIG.

  • the opening wedge 314 is not indispensable in this embodiment.
  • FIGS. 18 and 19 could also be used with fastener halves of the same general profile formed in one piece, e.g., as a monofilamentary coil or an extruded profile of the type shown in the preceding embodiments, rather than in discrete links held together by an associated stringer tape.
