Definitions

  • This invention relates to sliders for slide fasteners of the so-called releasable type having means incorporated therewith for permitting selective spacing of the slider wings relative to one another, and particularly, to an improvement in or modification of the invention described and claimed in my co-pending application, Serial No. 349,914, filed April 20, 1953.
  • the present invention consists in an improved construction of the slider shown in the above identified application so as to provide an automatic locking arrangement on the slider for locking the slider at any point along the fastener elements as well as a releasable arrangement for the wings of the slider so that the slider wings may be selectively spaced a predetermined spaced distance apart in order to facilitate the freeing of the sliders from clothing or other foreign materials when accidentally caught therein, which sometimes happens upon longitudinal movement of the slider along ⁇ the fastener elements to engage and disengage the same.
  • manual means such as a latch member for permitting relative planar separation of the wings so as to define at least two positive spread positions or spacings, which positions or spacings are assumed automatically upon manual operation of the aforesaid latch member and which latch member is automatically returned to its normal position together with said wings by a biasing means which also functions to urge the locking member to its locked position.
  • Fig. 1 is a plan view, partly broken away, of a slide fastener having the improved slider of my invention incorporated therewith;
  • Fig. 2 is a side view of the fastener as shown in 7, partly in section and partly broken away to facilitate illustration, 4showing the locking member in its locked position;
  • Fig. 3 is a side view similar to Fig. 2 showing the locking member in its unlocked position
  • Fig. 4 is a sectional View taken on line 4 4 of Fig. 1;
  • Fig. 5 is a side view, partly broken away, of the improved slider of the present invention showing the slider wings and parts in their normal operating positions;
  • Fig. 6 is a side View, similar to Fig. 5, showing the slider parts in position to effect spreading of the wings to a predetermined spaced position;
  • Fig. 7 is a plan view of the slider body with both latch and locking members removed therefrom;
  • Fig. 8 is a perspective view of the latch member
  • Fig. 9 is a perspective view of the locking member.
  • the improved slider of my invention is shown incorporated with a conventional type slide fastener which consists of a pair of Stringer tapes 50 having a series of spaced-apart interlocking fastener elements 51 arranged along their opposed edges with the slider arranged thereon for longitudinal movement therealong for engaging and disengaging the fastener elements in a well-known manner.
  • a conventional type slide fastener which consists of a pair of Stringer tapes 50 having a series of spaced-apart interlocking fastener elements 51 arranged along their opposed edges with the slider arranged thereon for longitudinal movement therealong for engaging and disengaging the fastener elements in a well-known manner.

  • This enlarged head portion 14 preferably has side portions extending transversely to either side of the aperture 13 on the outer side of the wing 2. On the lower side of each of these side portions there is arranged a cam-like portion 15 which co-operates with a pair of recesses or grooves 16 and 17 arranged in side-by-side relation in the upper surface of the wing 2 to either side of the grooves 16 are shallower than, the outer grooves 17.
  • the inner side of the head portion 14 has preferably an inclined. r beveled. cam, surfaseas at 18.l
  • a lug portionZS'to which Vthere is pivotally attached, as at 26, an elongated cap-like locking member 27, whiclrisk Vshown in detail in Fig. 9.
  • This locking member has a top wall side, walls 28 and a rear and front,V walls 29'- and 30, respectively.
  • v There is also provided a rearwardly extending beveled or tapered portion 31 which normally rests on and cooperates with the inclined or beveled surface 1'8'of the latchmember 10 for av purpose hereinafter to be described.
  • a locking prong portion 32 which extends into and through an aperture 33 in the lower end of the slider and into the channel of the slider for engagement with andV between the fastener elements to lock the slider in a well known manner.
  • the forward wall 30 of this locking member 27 terminates in an inturned portion 34 which is adapted to engage a shoulder 35 arranged on a lug 36 which is positioned adjacent the lower end ⁇ of the wing'v 2 for limiting the outward movement ofthe locking member when the slider is manipulated to open and close the fastener, as more clearly shown in Fig. 3.
  • a pull member 37 having a trunnion portion 38 which is disposed in the space between the lugs'25- and 36 and under the locking member 27 and extends out through openings 39 in the side walls28 thereofn so as to be pivotally attached tothe slider body.
  • a rectangular-shaped recess 40,l At a spaced distance from this trunnion portion 38 in the pull' member 37, there is arrangedtherein preferably a rectangular-shaped recess 40,l so as to provide an inner camming wall portion 41 for a purpose hereinafter to be described.
  • the slider parts function in the following manner.
  • the wings- 2- and 3 are lin their normal spaced-apart operating positions with the cam portions 15 of the enlarged head portion 14 of the latch member 10 positioned' andV seated inthe shallow or inner grooves 16. on the outer surface of theA wing 2as shown in Figs. l, 2 and 5 of the drawings, so as to prevent normally the wings fromI moving apart.
  • the pull member 37 is moved to its uppermost position about its pivotal connection with the lug 13 so that the inner edge, of the wall portion 41 formed by the recess 40 in the pull member rests on the inclined' or beveled surface 1,8 of the enlargedheadv portion 14 ⁇ of the latch member 10.
