Definitions

  • Sliders for slide fasteners usually comprise a slider body and a pull attachin member formed as loop projecting above the surface of the slider body. Itis customary to mold the slider body and the pull attaching member either in a single piece, or to form them as separate members and subsequently attach them to one another. When the slider body and the pull attaching member form a single piece the pull tab must be formed as open or slotted loop in order that it can be introduced into the pull attaching member whereafter it must be squeezed together. In this case it can happen that the pull tab is pulled off from its attaching member when exerting a pulling action on the tab.
  • sliders which are molded from artificial resin materials and the like it is however possible to place a pull tab having a closed loop into the empty mold prior to forming the slider and then to mold the slider with the pull attaching member traversing a closed loop pull tab in a single piece.
  • This method of molding sliders however is complicated and can be used only for pull tabs of particular shapes.
  • the object of the invention is the provision of a slider which can consist of metallic or nonmetallic materials, and which comprises a slider body and a pull attaching member,'formed as separate parts, the two parts-being provided with cooperating portions. engaging each other for securing the pull attaching member to the slider body without the use of supplementary fastening members.
  • a further object of the invention is the provision of a method for making sliders of metallic or non-metallic materials and being formed by a slider body and a separate pull attaching member, which method avoidsthe above mentioned inconveniences and provides an easy, simple and reliablefastening of the two parts one to the other. 4

  • the two upper and lower narrow sides of the pull attaching member are then pressed inwardly as shown in Figs.,50 and 53 so as to form wall portions I29 engaging behind the projections I20 and I2I and preventing removal of the pull attaching member from the slider body.
  • the cap member 52 in turn is maintained in its position by the surfaces I2I of the pull attaching member, and the upper end I25 of the locking spring is engaged in the slot I23 between the abutment I20 and the wall surface of the pull attaching member and cannot be removed from its position.
  • the pull attaching member I30 is U-shaped in cross section and is formed at its upper end with an extension I3I having an opening I32 engaging with play over a projection I33 of the slider body 40.
  • the lower portion of the pull attaching member 4I extends through an opening I34 of the upper wing 43 and is provided with a. locking prong I35 capable of penetrating betweensuccessive fastener members of the slide fastener stringers along which the slider can move.
  • the pull attaching member At its lower end the pull attaching member is provided with an extension I36 which is bent downwardly and engages behind a web I31 projecting beyond the plane of the upper wing 43.
  • the lateral walls of the pull attaching member are provided with recesses I39 for receiving the pull tab, not represented.
  • This latter is maintained on the slider body by flanging its edge portion about the edge of the upper plate, and is provided with the necessary openings to give passage to the extension I3I and to the projection I40, as well as to the locking prong I35 and to the extension I36.
  • a tongue MI is cut out from the upper portion of the cap member 52, and an opening I42 permits insertion of the spring I38 after the cap member 52 has been secured to the slider body. After securing the cap member in its position and insertion of the spring I38, the pull attaching member I30 is placed in its correct position on the slider body and then the tongue I of the cap member is pressed inwardly until it abuts against the upper face of the extension Ill oi the pull attaching member, as shown in Figs. 54 and 55.
  • the pull attaching member now cannot move any more in longitudinal direction, but is maintained on the slider body by the tongue I of the cap member and by the web I91 the upper wing 43, and can only effect a limited rocking movement required for engaging and disengaging the locking prong I35.
  • the cap member 52 covering the upper wing 43 is secured to the slider body by bending its edge portion over the edge of the upper wing.
  • a recess I43 is provided in the upper wing (Fig. 62) at both sides of which the material of the upper wing originally forms projections I44.
  • the upper end I45 of the locking spring is inserted into the recess I43 and the material of the projections I44 is then pressed over the spring end I45 (Fig. 59) so that the spring is fixedly clamped in the slider body.
  • the locking prong 62 oi the spring 59 extends through an opening I46 in the upper wing 43.
  • a recess I41 is provided on the top of the slider body and a hook-shaped end I48 of an extension I49 of the pull attaching member.engages in this recess I41.
  • the lower end or the pull attaching member is provided with a downwardly bent extension I50 engaging behind the web IUI adjacent to the opening I46 of the upper wing 43.
  • the cap member 52 is provided with an opening I52 giving passage to the extension I49 of the pull attaching member, and with a. tongue I similar to that shown in Figs. 54 and 56.
  • the tongue I of the cap member is pressed downwardly until it abuts against the upper face of the extension I49 of the pull attaching member as shown in Fig. 58.
  • the pull attaching member cannot move any more in longitudinal direction and the bent down end I49 of the extension I49 cannot release from engagement behind the projection I" of the upper wing 43, while the lower extension I50 of the pull attaching member remains engaged behind the web II.
  • the abutment surface I94 of the pull attaching member lying against the cap member 52 assists in maintaining the cap member on the slider body.
  • the spring 59 in its locking position abuts against two projections I59 and I59 of the upper wing 43.
  • The'projection I59 also serves as abutment for the not represented pull tab, so that the pull attaching member is partially relieved from the action of the pulling effort when the slider is upwardly pulled as seen; in Fig. 58.
  • the slider shown in Figs. 60 and 61 is similar to that represented in Figs. 58 and 59.
  • Th extension I49 of the pull attaching member H is not bent down as in Fig. 58 but is originally straight.
  • the extension I 49 is inserted through a corresponding opening in the cap member into the recess I41 of the slider body (Fig. 60).
  • pressure is exerted from above on the portion of the cap member 52 extendin over the upper edge of the slider body to bend the extension I49 into th recess I41, so that this extension engages behind the projection I53 of the upper wing of the slider body.
  • the spring end I of the locking spring is attached to the slider body in the same manner as described with reference to Figs. 58 and 59.
  • a slider for slide fasteners comprising a slider body having an aperture therein, a pull tab and an attaching member, the pull tab having a portion thereof extending between the attaching member and the body, there being a slider locking detent present, said detent being secured at one of its ends between the body and an overlying part of said attaching member and extending away from said end, then extending between said portion of the pull tab and the attaching member and finally terminating in a locking prong that projects through said aperture in said body in a plane at right angles to the plane of such secured end portion, whereby a pull upon said pull tab move said locking prong into an inoperative position.
  • a slider of the construction set forth in claim 1 wherein such secured part of said slider locking detent has a T shaped head, seated in a complementary recess. so as to anchor the same securely against movement longitudinally or transversely with respect to said slider body.
