Definitions

  • ABSTRACT A separable slide fastener includes a retainer having a channel therein for receiving interengaging elements of a stringer, the retainer being movable along the interengaging elements to a support member to be immovably mounted on the support member with a head portion of the support member locked in a pocket in the channel of the retainer.
  • Separable slide fasteners are conventionally utilized in many articles in order to permit complete separation of the portions of the article carrying respective slide fastener halves.
  • a bottom stop for the slide fastener is conventionally constructed with a retainer secured to one tape thereof to prevent the slider of the slide fastener from being removed from the interengaging elements and further to receive a pin carried at the end of the other tape of the slide fastener.
  • the slider is moved to abut the retainer and the pin is inserted through the channel in the slider and into the retainer such that the slider can then be moved along the interengaging elements to engage the same.
  • a separable slide fastener having a pair of tapes carrying interengaging elements along inner edges thereof, a slider movable along the interengaging elements to open and close the slide fastener, and a separable end stop including a support member secured to one of the tapes having a head portion, a pin member secured to the other of the tapes, and a retainer immovably mounted on the support member having first and second opposing side walls, a partition disposed between the first and second side walls to define first and second channels in the retainer for receiving the support member and the pin member, respectively, and means in the first channel defining a pocket having a configuration mating with the configuration of the head portion of the support member to lock the head portion in the pocket.
  • the present invention is further generally summarized in a method of forming a half of a separable slide fastener including the steps of gapping a stringer to remove interengaging elements from a portion thereof, assembling a retainer on the stringer, forming a support member on the stringer, moving the retainer along the stringer to the support member, and locking the retainer on the support member.
  • a further object of the present invention is to provide a method of forming a half of a separable slide fastener by assembling a retainer on a stringer, forming a support member at the end of the stringer, moving the retainer to the support member, and forcing a head portion of the support member into a pocket formed in the retainer to lock the retainer on the support member.
  • Another object of the present invention is to construct a retainer for a separable slide fastener having opposing side walls with a partition therein defining first and second channels for receiving a support member and a pin member, respectively, the first channel having a pocket formed therein with a configuration mating with the configuration of a head portion of the support member to lock the support member with the retainer and the second channel having a configuration to receive the pin member to permit closing ofthe slide fastener.
  • the present invention has an additional object in the forming of a stop member with a wedge-shaped head portion in order to facilitate assembly of the support member with a retainer, the head portion having an end wider than the mouth of a pocket formed in the retainer such that the head portion is deformed during assembly with the retainer.
  • Yet another object of the present invention is to con struct a retainer to have a pocket therein for locking engagement with a head portion of a support member, the pocket being defined by islands extending from a pair of wings of the retainer and having edges contacting an inner side of the support member at the head portion and permitting slight tilting of the retainer during insertion of a pin member therein to close the slide fastener.
  • An additional object of the present invention is to provide a retainer having a slider-like construction for a separable slide fastener with a partition of the retainer having a recess formed therein to permit passage of the interengaging elements of the slide fastener.
  • the retainer can be initially assembled on a stringer and then moved into locking engagement with a support member secured to the stringer without any additional securing step, the ends of the stringers of the separable slide fastener are received in the retainer so as not to extend therefrom thereby eliminating stress, the channel through the retainer is configured to permit the retainer to move along the interengaging elements of the slide fastener and the support member is constructed of a plastic material to permit deforming thereof as the retainer is locked on the support member.
  • FIGS. I and 2 are plan views of a separable slide fastener according to the present invention in closed and open states, respectively.
  • FIG. 3 is a broken perspective of the retainer of the separable slide fastener of the present invention.

  • the side wall 96 joins the side wall 90 at a rounded edge 100 laterally displaced from the longitudinal axis of the retainer.
  • a pocket, generally indicated at 102, is formed in channel 84 and defined by bosses 104 and I06 extending laterally from side wall 92 of the partition 64 and inwardly from the wings 60 and 62, respectively, along with bosses 108 and 110 extending laterally from flanges 66 and 70 and inwardly from wings 60 and 62, respectively.
  • the pocket 102 is further defined by islands 112 and 114 extending from wings 60 and 62, respectively, adjacent the recess 98 in partition 64 and protruding beyond edge 100 at the end 76 of the retainer.
  • the pocket 102 as defined by bosses 104, I06, 108 and 110 and islands 112 and 114, has a configuration mating with the configuration of the head portion 40 of support member 26, as best illustrated in FIG. 4, with the flaring side 38 of the head portion engaging bosses I08 and 110 and the inner side 34 engaging the islands I12 and 114 while the corner of the head portion where end 41 joins side 34 is captured by abutment with the ends of bosses 104 and 106.
  • a pair of slide fastener stringers are initially produced, such stringers each including a carrier tape with filamentary interengaging elements along the edges thereof, as illustrated in FIG. 7, wherein the stringers are given reference numbers corresponding to the slide fastener as described above. Portions of the stringers are gapped and cleaned in order to remove interengaging elements therefrom as indicated at 116 on tape 12 and 118 on tape 14 in FIG. 7.
  • the production of slide fastener stringers using filamentary interengaging elements and the gapping and cleaning of portions thereof is conventional and well known in the art; and, accordingly, no detailed description thereof follows.
  • the slider 20 is assembled with the interengaging elements 16 by in troducing the slider at the gapped portion 116, and the retainer 30 is similarly assembled with the interengaging elements 16 by introducing the end 76 of the retainer at the gapped portion 116 and moving the retainer 30 such that the interengaging elements I6 pass through the channel 84 in the retainer, the recess 98 in the partition accommodating the interengaging elements 16 to permit passage through the channel.
  • the tapes l2 and 14 are forwarded to an end stop forming apparatus where the support member 26 and the pin member 28 of the separating bottom stop and the top stop members 22 and 24 are simultaneously formed at the junctures of gapped portions 116 and 118 with interengaging elements l6 and 18, respectively, as illustrated in FIG. 8.
  • the members 22, 24, 26 and 28 are preferably constructed of a thermally fusible plastic material and can be formed by molding to the tape or preforming the members and then ultrasonically fusing the members onto the tape. The techniques for the production of such stop members are well known in the art and are not described in detail hereinafter.
  • the retainer 30 With the slide fastener chain in the condition illustrated in FIG. 8, the stringers are cut at the gapped portions to separate individual slide fasteners and thereaf ter the retainer 30 is moved along the interengaging elements 16 to the support member 26. With the retainer in this position, sufficient force is applied to retainer 30 to force the end 41 of the head portion of the support member 26 through the mouth between bosses 104, H16 and bosses 108, 110, the construction of the support member of a plastic material permitting the head portion to deform to pass by the bosses and into the pocket 102. Once the head portion is received in the pocket, it is fixedly captured due to the abutment of end 41 with the ends of bosses 104 and 106 and the mating configuration of the head portion with the pocket. Accordingly, the retainer 30 cannot be moved either onto the interengaging elements 16 or off of the support member 26 and is firmly locked in place.
  • the slider 20 can be moved down the interengaging elements 16 to abut the end 76 of the retainer and thereafter the pin member 28 is inserted through the slider 20 and into the channel 86 until the edge of flap 58 abuts wall 82. With the pin member in this position, guide tooth 56 will be positioned between the terminal interengaging elements l6 and the end of flange 42, and the slider can be moved upward to close the slide fastener.
  • the method of forming half of a separable slide fastener in accordance with the present invention requires only the assembling of the retainer on the interengaging elements of the stringer, forming the support member, moving the retainer to the support member and locking the retainer on the support member by forcing the wedge-shaped head portion of the support member through the narrower mouth of the pocket in the retainer to deform the support member and lock it in the pocket.
  • the retainer be formed of a relatively strong material, preferably die cast of metal, while the support member is formed of a deformable material, preferably plastic.
  • the wedgeshaped configuration of the head portion of the support member facilitates forcing of the head portion through the mouth of the pocket and further assures nonmovement of the retainer relative to the support member once the support member and retainer are interlocked.
  • the slight angular orientation of the edges of the islands extending from the wings of the retainer permits the inner wall of the support member at the head portion to engage the edges of the islands while permitting slight tilting of the retainer during insertion of the pin member therein in order to close the slide fastener.
