Definitions

  • the device comprises a pair of release arms pivotally supported on the guide struc ture in opposed relationship to each other and yieldably urged into abutment against the opposite surfaces, respectively, of the support structure when the same is held in its most elevated position, Upon descent of the support structure into the guide structure, the free ends of the release arms slide along the respective opposite surfaces of the support structure to engage the slider mounted in upside-down disposition on the slider rest and hence to release the slider from the slider rest as the support structure continues descending to its most depressed position within the guide structure.
  • This invention relates to a device for holding a slider during assemblage therethrough of a fastener chain or a pair of fastener stringers. More specifically, the invention concerns some improvements in such slider holder whereby the slider is automatically released therefrom each time the fastener chain has been threaded through the guide channels of the slider.
  • an object of this invention to provide an improved slider holder wherein the slider can be automatically released following assemblage of a fastener chain therethrough, so that slide fasteners can be assembled continuously in a truly efficient manner.
  • Another object of the invention is to provide a simple, inexpensive, and absolutely self-actuated release mechanism whereby the slider can be released unfailingly from the slider holder without any possibility of causing trouble in its functioning.
  • a slider holder of the type including an upright support structure having a slider rest on its top and slidably mounted in a hollow guide structure for up-and-down motion therethrough.
  • a slider is placed upside down on the slider rest in a depressed position of the support structure within the guide structure, and a fastener chain is assembled through the slider in the most elevated position of the support structure.
  • a pair of opposed release arms are pivotally supported on the guide structure and are spring-energized toward each other.
  • the free ends of the release arms slide along the respective opposite surfaces of the support structure to engage the assembled slider and hence to release the same from the slider rest as the support structure continues descending to its depressed position for receiving the next slider.
  • the vertical reciprocation of the support structure within the guide structure is thus utilized for automatic release of the successive assembled sliders from the slider rest, so that no actuating mechanism is required for the operation of the release arms.
  • FIG. 1 is a perspective view of a slider holder constructed in accordance with the novel concepts of this invention
  • FIG. 2 is a partly broken away side elevational view of the slider holder of FIG. I, in which the support structure is shown in its fully elevated position;
  • FIG. 3 is a top plan view of the arrangement of FIG. 2;
  • FIG. 4 is a vertical sectional view of the slider holder in which the support structure is shown in its depressed position.
  • the slider holder illustrated therein by way of a'preferred embodiment of this invention is broadly comprised of an upright support structure 10, a hollow guide structure 11. and a feed mechanism 12.
  • the support structure 10 is slidably mounted within the guide structure 11 for up-anddown motion therethrough and includes an upper portion 13 of substantially pyramidal shape which projects upwardly of the guide structure when the support structure is in its most elevated position.
  • a slider rest adapted to fixedly support a slider 14 of the usual construction placed upside down thereon, as hereinafter set forth in more detail.
  • the slider rest includes a first channel 15 adapted to receive a lug 16 arranged longitudinally on the channeled body of the slider 14 and a second channel 17 adapted to receive a pull tab 18 pivotally and slidably attached to the lug 16.
  • the first and second channels 15 and 17 are thus disposed at right angles with each other on the top of the support structure 10.
  • the slider rest differs in form with the type of slider 14 used. Where the tab 18 projects directly from the slider body in the absence of lug 16, the first channel 15 may be dispensed with.
  • the hollow guide structure 11 may be mostly buried within a working table 19, and a pair of opposed slots 20 are formed vertically in the upper end portion of the guide structure projecting upwardly of the working table. As will be seen from FIGS. 1 and 3 in particular, the slots 20 are vertically aligned with the open lateral ends, respectively, of the aforesaid second channel 17 formed in the support structure 10.
  • release arms 21 Accommodated in the respective slots 20 with appropriate clearance is a cooperative pair of release arms 21 each pivotally supported at its bottom end by a shaft 22 extending across each slot. These release arms 21 are biased toward each other as by means of torsion springs 23 fitted over the respective shafts 22. The top ends of the release arms 21 are cut at such an-angle that they will offer horizontal surfaces in coplanar relationship when the release arms are turned to their operative positions shown in FIG. 4, in order to properly support the channeled body of the slider 14 thereon.
  • the opposed inside surfaces of the release arms 21 should be grooved or otherwise recessed longitudinally as indicated at 24 in FIGS. 1 and 3 in order that the lateral edges of the slider pull tab 18 may be received in such grooves.
  • guide grooves 25 should be formed on the opposite surfaces of the upper portion 13 of the support structure to direct the respective release arms 21 therealong and further to permit their grooved upper end portions to positively engage the slider 14 upon descent of the support structure into the guide structure 11.
  • the feed mechanism 12 may be of any known or suitable configuration as long as the same is capable of delivering successive sliders in upside-down disposition onto the slider rest.
  • each slider 14 which has been conveyed by the feed mechanism 12 is deposited upside down on the slider rest on the top of the support structure 10 when the same is in its depressed position within the guide structure 11.
  • the slider thus placed on the slider rest, of course, has its lug l6 neatly received in the first channel 15 and its pull tab 18 in the second channel 17.
  • the support structure 10 is then caused to rise, by any suitable means known to the specialists, through the guide structure 11 to its fully elevated position illustrated in FIGS. 1 and 2, thereby causing the grooved upper ends of the release arms 21 to turn away from each other to their inoperative or standby positions against the forces of the respective torsion springs 23.
  • the released slider 14 together with the assembled stringers may be manually removed from over the guide structure 11.
  • the slider can be left supported on the release arms 21 because it can be automatically cast off by the support structure 10 as the same succeedingly rises to carry the next slider 14a, P16. 4, to its fully elevated position. The same procedure may thereafter be repeated to allow for a faster operation in assembling the fastener stringers through the successive sliders.
  • this slider holder be provided with means for securely locking the slider in position on the slider rest at least while the support structure 10 is held in its most elevated position. Any displacement or detachment of the slider from the slider rest can thus be prevented during assemblage of the fastener stringers therethrough.
  • the slider must of course be unlocked as the support structure starts descending, in order to be properly released from the slider rest by the release arms 21 as hereinbefore described.
  • a device for holding a slider during assemblage of a fastener chain therethrough wherein the slider includes a channeled body and a pull tab pivotally attached thereto, the combination of:
  • a slider rest formed on the top of said support structure to hold the slider in upside-down disposition thereon, said slider rest including at least one channel extending downwardly therefrom to receive the pull tab of the slider, so that the fastener chain can be manipulated through the channeled body of the slider in said most elevated position of said support structure;
