Definitions

  • This invention relates to a slider holding device for releasably holding sliders while assembling a slide fastener chain therethrough.
  • Slider holders find most application in holding sliders in position for mounting on a slide fastener chain already attached to for example a garment fabric such as trouser flies.
  • Such slider holders in conventional use were designed such that the operator had to place and position the slider on the holder each time with hand, with the result that the rate of slider assembly was considerably retarded.
  • FIG. 1 is a partly sectional front elevation of a slider holder according to the invention, showing a slider mounted thereon for assembly on a slide fastener chain;
  • FIG. 2 is a similar view but showing the holder as in a position for receiving a slider prior to assembly thereof;
  • FIG. 3 is a perspective view of the slider holder of FIGS. 1 and 2, showing a typical mode of application of the same.
  • the slider holder 10 generally comprises a vertically elongated support structure 11 of generally square cross section having an interior guide channel 12 extending substantially to the full length of the structure 11, which guide channel is adapted to accommodate and guide a slider holding means hereinafter described.
  • Designated at 13 are frame members constituting the support structure 11, and one of which frame members specifically denoted by 13a is provided therein with a long vertical guide slot 14 for guiding the movement of a reciprocable connecting rod later described.
  • a frame member 13b Opposite to the said one frame member 13a is a frame member 13b which is provided therein with a short vertical guide slot 15 for receiving a crank-armed clamping means later described.
  • the slider holding means 16 has a slider mount 17 formed on the top end thereof for receiving the slider S and an opening 18 therein for accommodating the pull tab S, depending from the slider body.
  • Designated at 19 is a retaining means pivotally connected as at 20 to the slider holding means 16 and normally biased by a spring 21 in a direction to press the pull tab S, against a recessed inner wall 22 contiguous to the opening 18.
  • the movement of the slider holding means 16 is effected by the vertical stroke of the connecting rod 23 having at one end a horizontally projecting pin 24, which is fixedly connected to the slider holding means, and at the other end connected to a suitable driving means not shown.
  • the slider holding means 16 is thus movable vertically within the guide channel 12 between a first and a second position. In the first position wherein the slider holding means 16 is lowered, it receives the slider S as shown in FIG. 2 from a slider supplying means 25 movable into and away from the guide channel 12.
  • the slider supplying means 25 may be arranged to receive the sliders S for example one at a time from a suitable slider supply chute not shown. Further arrangement of the slider supplying means 25 is optional whereby it can move horizontally back and forth or turn arcuately in a horizontal plane into and away from the path of the slider holding means 16 in the guide channel 12, for which purpose the frame member or members 13 are provided with a lateral opening as at 26 through which the slider supplying means 25 is allowed to pass.
  • the retaining means 19 is brought into abutting engagement with a prong 27 projecting laterally from the frame member 13b and connected thereto by a compression spring 28.
  • This compression spring 28 is greater in tension than the aforesaid spring 21 so that abutting engagement of the retaining means 19 with the prong 27 causes the same to move against the tension of the spring 21 in a direction to release the pull tab S, as shown in FIG. 2.
  • the slider S is transferred from the supplying means 25 to the holding means 16 with the pull tab S, inserted dependently through the opening 18.
  • the retaining means 19 is disengaged from the prong 27 and urged by the spring 21 in a direction to press the pull tab against the recessed wall 22 thereby preventing the slider S from falling away prior to arrival at the second position.
  • the prong 27 comes into contact with an upwardly inclined cam surface 29 of the holding means 16 whereupon it is retracted away from the guide channel 12 against the tension of the spring 28.
  • Designated at 30 is the crank-armed clamping means for clamping the slider S carried on the slider holding means 16 which has arrived at the second position wherein the upward movement of the holding means 16 is terminated with the slider S on the mount 17 exposed above the top end of the support structure 11 to permit threading of the fastener chain F through the slider guide channel in the usual manner.
  • the clamping means 30 is pivotally connected to the frame member 13b as at 31.
  • One or first arm 30a of the clamping means 30 extends substantially vertically upward from the pivot 31 and has a hook-shaped projection 32 integrally formed at its free end for coming into and out of engagement with an aperture S in the pull tab S of the slider S.
  • the other or second arm 30b of the clamping means 30 extends horizontally from the pivot 31 substantially at right angles to the first recited arm 30a and has its free end pivotally connected as at 33 to a vertically extending connecting bar 34.
  • This bar has a conically shaped contact member 35 disposed at a midpart thereof for coming into and out of engagement with a limit switch 36. Engagement of the conical member 35 with the limit switch 36 causes the latter to close whereupon an actuating means not shown is energized to effect the downward stroke of the connecting rod 23 to lower the slider holding means 16 toward the first position.
  • a spring member 37 is connected between the other end of the connecting bar 34 and the pivotted end of the second recited arm 30b of the clamping means 30, and is adapted to normally urge the clamping means 30 in a direction in which the projection 32 engages in the pull tab aperture S of the slider S set in assembling position. Under the influence of the spring 37 the projection 32 pulls the pull tab S, downward so as to anchor the slider S firmly in place.
  • This arrangement also ensures that the locking element not shown of an automatically locking slider be retracted from the slider guide channel to permit running of the fastener chain F therethrough.
  • the slider S may be simply pulled apart from the holding means 16 or may be so pulled after depressing a pressure plate 38 (best shown in FIG. 3) attached to the arm 30b against the tension of the spring 37.
  • a pressure plate 38 (best shown in FIG. 3) attached to the arm 30b against the tension of the spring 37.
  • the clamping means 30 rotate under the influence of tension of the spring 37 until the projection 32 moves across the channel 12 and nearly reaches the frame member 13a as depicted in FIG. 2.
  • the absence of the slider S is sensed by the clamping means 30 in such a manner that the conical contact member 35 engages with and closes the limit switch 36 with results aforementioned.
  • Designated at 39 is a table on which the assembling operation may be conveniently performed and which has an opening 40 through which the upper portion of the slider holder 10 is exposed as depicted in FIG. 3.
  • a slider holder for releasably holding sliders while assembling a slide fastener chain therethrough which slider holder comprises:
  • a slider holding means movable within said opening between a first and a second position
  • a slider supplying means movable into and away from said opening and supplying sliders to said slider holding means at said second position.
  • a slider holder as defined in claim 1 which includes a crank-armed clamping means pivotally connected to said support structure and having a hookshaped projection engageable with the slider to retain the latter in position.
