Definitions

  • a bridge top stop consists of a body typically comprising a pair of wings or plate members interconnected at their lower ends by a central web or coupling link of wedge-shaped cross section.
  • One of the plate members has a pair of flanges along its lateral edges, which flanges cooperate with the wedge-shaped web to form a downwardly diverging, inverted Y-shaped guide channel through the bridge top stop body for reception of fastener elements therein.
  • the opposed inside edge portions of the stringers are manipulated into and through the inverted Y- shaped guide channel of the top stop body from its lower end, just as when a pair of such stringers is threaded through the similar guide channel of the usual slider for slide fastener assemblage.
  • Some of the fastener elements including the topmost ones of the respective stringers will interengage within the top stop body.
  • This invention relates generally to slide fasteners and in particular to what is commonly referred to as bridge top stops whose primary function is to inseparably connect the upper ends of the stringers of a slide fastener for limiting the upward movement of a slider in the operation of coupling or closing the fastener stringers.
  • bridge top stops As is well known, slide fasteners equipped with bridge top stops of the character described have found extensive use in garment placket and other closure openings including those in bags, suitcases and like articles. While a wide variety of bridge top stops have been proposed and used in the art, most of them have been found not entirely satisfactory in that, for instance, such prior art bridge top stops cannot be easily mounted in position adjacent the upper ends of a pair of fastener stringers, requiring undue attention on the part of the workman to the relative positioning of the stringers and the top stop. This difficulty arises, among other reasons, from the fact that the prior art bridge top stops are usually clamped or otherwise secured directly onto the reinforced or beaded edges of the stringer tapes.
  • Another object of the invention is to provide a bridge top stop which can be mounted on the fastener stringers with sufficient mechanical strength and positional stability to remain in service over extended lengths of time.
  • a further object of the invention is to provide a bridge top stop which can be formed of either metallic or thermoplastic material, with equally favorable manufactural and operational characteristics.
  • this invention contemplates the provision of a bridge top stop of the character referred to, which includes a body having a downwardly diverging, inverted Y-shaped guide channel therethrough for receiving corresponding parts of rows of interlocking fastener elements carried along the respective inside edges of a pair of fastener stringer tapes.
  • the opposed inside edges of these stringers are threaded through the inverted Y-shaped guide channelof the stop body, just as through the guide channel of the conventional slider, until the topmost fastener elements on the respective stringer tapes reach its upper end, with the result that some of the fastener elements including the topmost ones interengage in the guide channel of the top stop.
  • the bridge top stop according to the invention can thus be substantially integrally united with parts of the rows of fastener elements throughout the entire longitudinal dimension thereof.
  • the stop can be mounted in position on the stringers with high mechanical stability and is further effective to retain the fastener elements of the respective stringers in their correct relative positions.
  • FIG. 1 is a fragmentary top plan view of a slide fastener incorporating the bridge top stop according to this invention
  • FIG. 2 is a perspective view of the bridge top stop shown in FIG. 1;
  • FIG. 3 is a sectional view showing the inside surface of a top wing or plate member in the bridge top stop of FIGS. 1 and 2;
  • FIG. 4 is a sectional view taken along the plane of line IVIV in FIG. 1;
  • FIG. 5 is a perspective view of another preferred embodiment of the invention.
  • FIG. 6 is a view similar to FIG. 4 but showing the embodiment of FIG. 5 mounted in position on a pair of fastener stringers;
  • FIG. 7 is a schematic longitudinal sectional view explanatory of a further preferred embodiment of the invention.
  • FIG. 1 DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference is first directed to FIG. 1 to briefly describe the general organization of a slide fastener employing the bridge top stop according to this invention.
  • the illustrated slide fastener comprises a pair of stringers generally designated 10 and 11, respectively.
  • Each stringer includes a tape 12 having along the reinforced inside edge 13 thereof a row of interlocking fastener elements 14 of any known or suitable type anchored thereto in a suitable manner.
  • the rows of fastener elements 14 can be engaged and disengaged relative to each other by a conventional slider, also not shown, which is slidable therealong.
  • the reference numeral 15 generally designates a preferred form of the bridge top stop according to this invention.
  • the bridge top stop 15 has a substantially dovetail-shaped body 16 comprising a pair of similar wings or plate members 17 and 18 interconnected at their lower ends by a centrally located web or neck 19 of wedge-shaped cross section.
  • the opposite lateral sides of the top wing 17 terminate in downward flanges 20 which are each slightly bent at an intermediate point and which cooperate with the wedgeshaped web 19 to form a downwardly diverging, inverted Y-shaped guide channel 21 for accepting the upper end portions of the rows of interlocking fastener elements 14 therein.
  • the lower end of the bridge top stop body 16 may be suitably concaved or recessed as seen in the drawings, thereby permitting the upper end portion of the unshown slider to fit snugly therein when the same is moved to its uppermost position to close the slider.
  • the inside edges 13 of these stringers may be threaded through the inverted Y-shaped guide channel 21 of the top stop body 16 from its lower end, in much the same way as when a pair of such stringers is manipulated through the guide channel of the usual slider for slide fastener assemblage.
  • the bridge top stop 15 is then shifted downwardly of the stringers l0 and 11 until the topmost ones of the'fastener elements 14 on the respective stringer tapes l2 reach the upper end of its body 16, as will be clearly seen from the showing of FIG. 1. It will also appear from a consideration of FIG. 1 that some of the fastener elements 14 including the topmost ones on the respective stringer tapes interengage in the upper end portion of the inverted Y-shaped guide channel 21 of the top stop body 16.
  • the bridge top stop 15 is metal made, its top and bottom wings l7 and 18 may be mechanically compressed into positive clamping engagement with the pair of stringers l0 and 11 as illustrated in FIG. 1.
  • the bridge top stop 15 is formed of some synthetic resin of thermoplastic nature, on the other hand, then its wings l7 and 18 may be substantially integrally secured to the stringers l0 and 11 under application of heat and pressure, as by the known techniques of supersonic or high frequency heating.
  • the fastener elements with which the stop is intended for use may also be metal made, and where a thermoplastic top stop is employed, the fastener elements will likewise be thermoplastic.
  • FIGS. and 6 illustrate another preferred embodiment of the invention, in which the bridge top stop a has a single plate member 170 corresponding in function to the top wing 17 in the preceding embodiment of FIGS. 1 to 4.
  • the plate member 17a has on its inner surface a pair of flanges a extending along the respective lateral edges and a column 19a ofwedgeshaped cross section located centrally at the lower end. These flanges 20a and column 19a cooperate to form a downwardly diverging, inverted Y-shaped guide channel or groove 21a as in the preceding embodiment.
  • the bridge top stop 15a of this general configuration may be formed of thermoplastic material and, as illustrated in FIG. 6, mounted in position on the pair of fastener stringers 10 and 11 under application of heat and pressure. If desired, the inner surfaces of the plate member 17a defining the guide groove 210 may be knurled by way of slippage prevention. Other details of construction are substantially the same as those set forth in connection with the preceding embodiment.
  • FIG. 7 schematically illustrates another preferred embodiment of the invention which assumes the use of metal for both fastener elements 14a and bridge top stop 15b.
  • the bridge top stop 15b also comprises top and bottom wings or plate members 17b and 18b interconnected and configured so as to define a downwardly diverging, that is, inverted Y-shaped guide channel therethrough as in the embodiment shown in FIGS. 1 to 4.
  • This bridge top stop 15b can also be mounted in position on the pair of fastener stringers by compressing its top and bottom wings 17b and 18b toward each other.
  • this final embodiment of the invention features a plurality of longitudinally spaced teeth 22 which are formed on the inside surface of the bottom wing 18b, or of the top wing 17b if desired, by inwardly raising parts of the wing as seen in the drawing. These teeth 22 are intended to project into the spacings between the fastener elements 14a for added positional stability.
  • a bridge top stop comprising a body adapted to be secured in position to the adjacent edges of said pair of stringers, and means on said body for defining a downwardly diverging, inverted Y- shaped guide channel therethrough, said guide channel being adapted to receive corresponding parts of said rows of fastener elements throughout the entire length thereof, in such a manner that some of the fastener elements including the topmost ones of the respective stringers interengage within said body.
