Definitions

  • the present invention relates to a slide fastener slider comprising a slider body, a pull tab support pivotably connected at one end to the slider body, a pull tab removably attached to the opposite end of the pull tab support, and means for detachably connecting the pull tab and the pull tab support, said pull tab support having at the opposite end an aperture and a support portion comprising a rod defining one side of said aperture, said pull tab having neck portion normally received in said aperture, and an opening in said neck portion normally receiving therein said support portion and said connecting means comprising a resilient pull tab retainer movable between a first position under its own resiliency and a second position against its own resiliency.
  • a slide fastener slider of this type is disclosed in US-A-2811 763.
  • the pull tab support is formed with an opening and pull tab is provided with a hook-like support portion defining an aperture.
  • the pull tab also comprises a resilient retainer that normally closes the aperture defined by said hook-like support portion.
  • WO 80/02494 describes a slide fastener slider whose pull tab support comprises a resilient tongue projecting into an elongate aperture of the pull tab and rearwardly engaging a shoulder of the pull tab.
  • pull tab support comprises a resilient tongue projecting into an elongate aperture of the pull tab and rearwardly engaging a shoulder of the pull tab.
  • the invention aims at improving the slide fastener slider of the type mentioned above in respect to the mechanical strength thereof, for the connection between the pull tab and the pull tab support to withstand great tensile forces.
  • a slide fastener slider satisfying this requirement is characterized in that said resilient pull tab retainer is disposed on said pull tab support, the wall of said pull tab support has a recessed thin portion adjacent said aperture, said thin portion including a channel extending alongside said rod from the outer edge of said pull tab support to said aperture, said neck portion comprises a sleeve, said opening being defined in said sleeve for receiving therein said rod, said sleeve having a longitudinal slit having a width wide enough to allow said thin portion to pass therethrough, but narrow enough to prevent said rod from passing therethrough, said resilient pull tab retainer normally closing said channel in its first position and being displaced out of said channel in its second position in order to disengage said pull tab from said pull tab support.
  • the pull tab can be attached to and detached from the pull tab support quickly in a simple operation.
  • the pull tab retainer is relatively simple in construction and hence can operate reliably and stably for an extended period of time.
  • the overall slider structure is accordingly relatively simple and can be assembled through a simple and timesaving procedure which easily lends itself to automation.
  • the pull tab can therefore be replaced with other pull tabs to suit desired application or meet users's preference.
  • the slide fastener slider 20 generally comprises a slider body 21, a pull tab support 22 pivotably connected at one end to the slider body 21, and a pull tab 23 detachably attached to the pull tab support 22.
  • the pull tab support 22 has a substantially oval opening 24 in one end thereof and a substantially rectangular aperture 25 in the opposite end thereof.
  • the opening 24 is partly defined by an arcuate pivot portion 26 pivotably connected to the slider body 21 (Figure 11).
  • the aperture 25 is defined, at its one side remote from said opening 24, by a straight support portion 27.
  • the support portion 27 is in the shape of a rod having an oval cross section ( Figure 3) and has an enlarged end 27' of circular cross section having a diameter D ( Figure 3) which is substantially the same as the length of the major axis of the oval cross section.
  • the pull tab 23 has at one end thereof a neck portion 28 and an opening 29 extending in and transversely through the neck portion 28.
  • the neck portion 28 is in the shape of a split sleeve having a longitudinal slit 30 ( Figures 3 and 4) communicating with the opening 29.
  • the opening 29 has a diameter which is larger than the diameter D of the end portion 27', and the slit 30 has a width W ( Figures 3 and 4) which is smaller than the diameter D and the length of the minor axis of the oval cross section of the support portion 27.
  • the pull tab 23 as it is mounted on the pull tab support 22 is pivotably movable with the opening 29 loosely receiving therein the support portion 27.
  • the pull tab support 22 is recessed in its opposite surfaces to form a thin portion 31 adjacent to the aperture 25, and a pair of channels 32, 33 extending parallel to the end 27' and communicating with the aperture 25.
  • the thin portion 31 has a thickness T ( Figure 3) which is smaller than the width W of the slit 30 in the neck portion 28 so that the latter can be moved through the channels 32, 33 in the directions of the arrowheads A ( Figures 2 and 4).
  • the thin portion 31 further has a recess 34 opening to the aperture 25 adjacent to the end 27'.
  • the channels 32, 33 are normally closed by a resilient pull tab retainer 35 acting as a torsion spring on the pull tab support 22.
  • the pull tab retainer 35 is generally U-shaped and comprises a pair of laterally spaced legs 36, 37 connected by a lateral joint 38 and a pair of confronting bent ends 39, 40 extending from the legs 36, 37 remotely from the lateral joint 38.
  • the lateral joint 38 is slightly twisted on itself such that the legs 36, 37 are normally out of lateral alignment with each other as shown in Figure 2.
  • the thin portion 31 has in its opposite surfaces a pair of holes 41, 42 located remotely from the aperture 25 and the channels 32, 33 and positioned out of lateral registry.
  • the pull tab retainer 35 is attached over the thin portion 31 across the channels 32, 33 with the bent ends 39, 40 pivotably fitted respectively in the holes 41, 42.
  • the shape of the pull tab retainer 35 and the position of the holes 41, 42 are selected such that the pull tab retainer 35 is normally urged under its own resiliency to move in the counter-clockwise direction indicated by the arrow B ( Figure 2) with the lateral joint 38 received in the recess 34, thus closing off the channels 32, 33.
  • the pull tab retainer 35 is angularly moved by fingers (not shown) in the direction of the arrow C ( Figure 2) against the resiliency of the retainer 35 until the retainer 35 is lifted clear out of the channels 32, 33.
  • the pull tab 23 can now be detached from the pull tab support 22 by pulling the neck portion 28 out through the channels 32, 33.
  • the pull tab retainer 35 can move in the direction of the arrow B under its own resiliency to close off the channels 32, 33 again when it is released from the finger pull.
  • Figures 5 through 8 show a modification according to the present invention in which a pull tab 43 is removably attached to a pull tab support 44.
  • the pull tab 43 and the pull tab support 44 are substantially the same as the pull tab 23 and the pull tab support 22 described above and shown in Figures 1 to 4 with the exception that the pull tab support 44 is recessed in one surface thereof to form a substantially rectangular thin portion 45 extending perpendicular to a support portion 46 along one end of an aperture 47.
  • the thin portion 45 has a thickness which is smaller than the width of a slit (not shown) in a neck portion 48 of the pull tab 43.
  • the pull tab support 44 further has a blind hole 49 extending parallel to the support portion 46 across the aperture 47, the hole 49 opening at one end 50 ( Figure 6) to the thin portion 45.
  • a stopper 51 extends on the thin portion 45 along an edge 52 thereof remote from the aperture 47 so as to define a gap 53 between the end 50 of the hole 49 and the stopper 51, there being also defined, between one or the lower end of the stopper 51 and one end 54 of the support portion 46, a channel 55 for the passage therethrough of the neck portion 48.
  • a substantially U-shaped, resilient pull tab retainer 56 is placed in the hole 49.
  • the pull tab retainer 56 has a pair of interconnected legs 57, 58 spaced from each other, the legs 57, 58 being snugly received in the blind hole 49.
  • the leg 58 has an outwardly bent end portion 59 extending through the gap 53 normally across the channel 55 to thereby prevent the neck portion 48 from being removed out of the aperture 47 through the channel 55.
  • the bent end portion 59 of the pull tab retainer 56 is lifted by a finger (not shown) inserted through the channel 55 against the resiliency of the retainer 56 until the bent end portion 59 abuts against the stopper 51 as shown in Figure 6. Then, the pull tab 43 is pulled off the pull tab support 44 by guiding the neck portion 48 through the channel 55. When released from the finger, the bent end portion 59 and hence the leg 58 is resiliently lowered to the position of Figure 5.
  • the neck portion 48 is pushed into the channel 55 to thereby force the bent end portion 59 to move upwardly out of the channel 55. At this time, the upward movement of the leg 58 may be assisted by a finger inserted through the channel 55. The neck portion 48 is finally moved past the bent end portion 59 into the aperture 47, and then the leg 58 springs downwardly back to the position of Figure 5.
  • a pull tab support 60 has in its one surface a substantially C-shaped recess 61 extending along and in spaced relation to an aperture 62.
  • the recess 61 communicates at one end with a groove 63 extending longitudinally in a support portion 64.
  • the opposite end of the recess 61 is held in communication with the aperture 62 to form a channel 65 for the passage therethrough of a neck portion 66 of a pull tab 67 (shown by phantom lines by clarity).
  • a generally U-shaped, resilient pull tab retainer 68 has a pair of interconnected legs 69, 70 spaced from each other and extending normally parallel to each other, the legs 69, 70 being positioned respectively in the recess 61 and the groove 63.
  • the leg 69 has an inwardly bent end portion 71 normally extending across the channel 65 to thereby prevent the pull tab 67 from displacing off the pull tab support 60.
  • the leg 70 is first placed in the groove 63 and then is secured to the support portion 64 by staking opposite edges 72, 73 of the groove 63.
  • the bent end portion 71 of the resilient pull tab retainer 68 is elevated by a finger (not shown) against the resiliency of the retainer 68 until the bent end portion 71 is displaced clear out of the channel 65. Then, the neck portion 66 is guided through the channel 65 into the aperture 62 as shown in Figure 10. When released from the finger, the retainer 68 can snappingly be returned to its normal position shown in Figure 9.
  • the neck portion 66 is pushed into the channel 65 against the bent end portion 71, which is forcibly moved upwardly against the resiliency of the retainer 68. The neck portion 66 is forced until it moves past the bent end portion 71 into the aperture 62. The retainer 68 then snaps downwardly to the normal position of Figure 9 in which the bent end portion 71 closes off the channel 65.
