Definitions

  • the present invention relates to a slider for a slide fastener, having a locking member adapted to cooperate with the fastener members of the fastener.
  • a slider for a slide fastener having a locking member adapted to cooperate with the fastener members of the fastener comprises a core piecearranged in the slide body so as to be pivotable in both pulling directions of the slider, said core piece bearing, in the operative position of a locking member having a locking arm and pivotable in the pivoting plane of the core piece about a supporting point of the slider body, with at least two spacedly arranged pressure points against said locking member, the latter being held in said operative position by a spring supported at the slider body, the core piece in the operative position of the locking member being in a middle position in which said pressure points in the pivoting plane of the core piece at both sides of the respective pivoting axle of the core piece lie on the same side of the supporting point of the locking member and serve to operate the latter in such manner that pivoting of the core piece out of its middle position in both directions results in a pivoting of the locking member against the action of the spring into inoperative position.
  • the lever arm required for producing the releasing force may be selected greater and also a greater pivoting distance is at disposal compared with the cases in which the pull member is used directly for actuating the locking member at its engagement point at the core piece.
  • such construction simplifies the manufacture of the core piece and the assembling of the slider.
  • FIGURE 1 is a front view of a first embodiment with the pull member removed.
  • FIGURE 2 is a longitudinal section through the slider of FIGURE 1, transversally with respect to the plane of the slider body, and with a locking member in operative position.
  • FIGURE 3 is a plan view of the slider of FIGURE 1.
  • FIGURES 4 and 5 each show a longitudinal section corresponding to that of FIGURE 2, but with the core piece pivoted in different directions.
  • FIGURE 6 is a front view similar to that of FIGURE 1 of a second embodiment.
  • FIGURE 7 is a longitudinal section corresponding to that of FIGURE 2 but through the slider of FIGURE 6.
  • FIGURE 8 is a front view similar to that of FIGURE 1 but of a third embodiment.
  • FIGURE 9 is a longitudinal section corresponding to that of FIGURE 2 but through the slider of FIGURE 8.
  • the slide fastener slider illustrated in FIGURES 1 to 5 comprises a two-part slider body or slider plate A and a core piece B made of one piece.
  • the portion 1 of the slider body A comprises in well known manner inwardly bent rim portions 2 forming the guiding channel of the slider for guiding the fastener members when the slider is displaced along the rows of fastener members.
  • the portion 1 of the body is further provided with a rectangular middle recess 3, which is Wedge-like tapered in its lower section.
  • two semi-cylindrical recesses 4 extending transversally to the longitudinal axis of portion 1 and coaxially with respect to each other.
  • These recesses 4 open into the middle recess 3 and they house cylindrical axle pins 5 of the core piece B inserted from the rear side of the slider body and through the middle recess thereof. These pins 5 project laterally outwardly from end flanges of the core piece B, said end flanges being formed by a longitudinal groove 6 in the rear side of the core piece B.
  • the recesses 4 constituting one of the bearing bushes for the pins 5 are completed by recesses 7 provided at the inner side of the cover portion 8 of the slider body A forming the second bearing bush.
  • the cover portion 8 secured to portion 1 closes the middle recess 3 of the body portions 1 towards the rear side.
  • the cover portion 8 On its inner side facing the core piece B the cover portion 8 has a longitudinal groove 9 extending in the middle thereof and opposite the longitudinal groove 6 of the core piece B.
  • This longitudinal groove 9 receives a leaf spring 10 elliptically vaulted outwardly.
  • the spring 10 loads with its dishing between the two pins 5 a locking member 11 arranged in the middle recess 3 of the body portion 1 and in the longitudinal groove 6 of the core B.
  • the head end of locking member 11 lies in an upper recess 3a of the slider body in such manner between a wall 12 of the portion 1 and a nose 13 that this locking member 11 is pivotable between two end positions about this supporting point in a plane perpendicular to the plane of the slider body.
  • the lower or free end portion 14 of the locking member 11 is bent forwardly and sidewardly and extends in operative position of the locking member through a recessed portion 6a of the groove 6, and transversally through one of the branches of the Y-shaped guiding channel of the slider body.
  • the middle portion of the locking member 11 abuts in operative position of the latterv a plane surface of the base of groove 6 of the core piece B.
  • the end edges 15, 16 of this plane base of the groove form a pair of spacedly arranged pressure points.
  • the pressure point 15 lies below and the pressure point 16 above the pivotal axis of the core piece formed by the axis of the pin 5 while both pressure points are below the supporting point 12, 13 of the locking member.
  • An eyelet 17 of the core piece B projecting out of the front side of the guiding channel of the slider body A serves to secure the pull member which is not shown.
  • FIGURE 2 shows the parts of the slider with the pull member not operated.
  • the leaf spring 10 presses the locking member 11 outwardly about the supporting point 12, 13 of the latter.
  • the whole base surface of the groove 6 including pressure points 15, 16 contacts the locking member. Consequently, locking arm 14 thereby projects in a known manner into the guiding channel of the slider.
  • the core piece B is pivoted with its pivoting pins 5 in direction of arrow b in FIGURE 5.
  • the upper pres sure point 16 thereby is pressed against the locking member 11 and pivots the latter against the action of spring about its supporting point 12, 13 in direction of arrow 0 so that the locking arm 14 is also pressed out of the guiding channel of the slider and the slider can freely be displaced upwardly.
  • the locking member returns automatically into its operative position under the action of the spring 10.
  • the slider illustrated in FIGURES 6 and 7 comprises a helical spring 20 in place of a leaf spring and its core piece B instead of being arranged with only one pair of axle pins is arranged in the slider body A with two pairs of axle pins 21, 22.
  • the body portion 1 is provided with two pairs of transversal recesses 23 having a semi-cylindrical base and these recesses are closed outwardly by appropriate semi-cylindrical recesses 24 at the inner side of the cover portion 8.
  • the axle pins 21 and 22, respectively are not only rotatable, but may also effect limited displacements in a direction parallel to themselves. Moreover the semi-cylindrical portions of these bearing openings have a diameter slightly superior to that of the axle pins 21, 22 so that the core piece may selectively pivot to a. certain extent about the axle of one or of the other of the two pairs of axle pins.
  • the pins 21 are arranged in the zone of the pressure point 16 and the pins 22 are arranged in the zone of the pressure point of the core piece B, whereby the axes of these pins lie within the distance separating the pressure points.
  • a boring 25 in the cover portion 8 said boring housing and supporting one end of the helical spring loading with its other end the locking member 11. Otherwise the slider of FIGURES 6 and 7 is of the same construction as the slider described with reference to FIGURES 1 to 5.
  • the core piece B analogously pivots about the axis of the lower pins 22 which remain in the position shown in FIGURE 7 as the pins 21 slide into the portion 24 of the bearing opening.
  • the pressure point 16 pivots the locking member 11 again in clock-wise direction shown in FIGURE 7 about its supporting point 12, 13 until the locking arm 14 releases the guiding channel of the slider.
  • the parts return into their starting position shown in FIGURE 7 under the action of pressure spring 20.
  • the slide fastener slider illustrated in FIGURES 8 and 9 as the one described with reference to FIGURES 1 to 5 comprises a slider body A made of two parts and having a middle recess 3, 3a, and a core piece B pivotally mounted in the slider body by means of a pair of axle pins 5.
  • the locking member 11a with its locking arm 14 is supported at 12, 13 in the recess 3a and is loaded as in the embodiment of FIGURES 6 and 7 by a helical spring 20 lodged in a boring 25 at the inner side of the cover portion 8 of the slider body A.
  • the locking member 11a has a widened middle portion from which is cut or stamped out a tongue 26.
  • This tongue forms a recess in the locking member and the helical spring 20 is supported by this tongue 26.
  • the longitudinal groove 27 of the core piece B which receives the locking member 11a is provided, between two eminences forming the pressure points 15a and 160, with a recess 2717 while the locking arm 14 in the operative position of the locking member 11:: as in the preceding embodiment extends transversal- 1y to one of the branches of the Y-shaped guiding channel.
  • the pressure point 15a is arranged below and the pressure point 16:: is arranged above the axis of the pins 5 while both pressure points are below the supporting point 12', 13 of the locking member 11a.
  • the operation of this slider provided with a twin eyelet 17a at the core piece B for a not represented pull member corresponds exactly to the operation of the slider described with reference to FIGURES 1 and 5.
  • a slide for a slide fastener having fastener members comprising a slider body, a pivotable core piece including a pivoting axle arranged in said slider body so as to be pivotable in both pulling directions of the slider about said pivoting axle, said core piece and slider body defining guiding channels for said fastener members, a pivotable locking member having a locking arm adapted to cooperate with the fastener members of the fastener, said locking member being pivotable in coplanar relation with said core piece between an operative and inoperative position, said slider body defining a support for said locking member said core piece including at least two end edge portions defining spaced pressure points, said locking member bearing on said pressure points with the locking member in said operative position, a spring supported on the slider body to resist pivoting of the locking memher, said pivoting axle being between said pressure points and said pressure points being on one side of the support for the locking member so that pivoting of the core piece in either direction causes pivoting of the locking member from an operative to an inoperative position.
  • a slider as claimed in claim 2 including a pair of axle pins provided at both sides of the groove for the locking member, the core piece being mounted in the slider body by said pair of axle pins.
