Definitions

  • Figs. 10 and 11 are transverse sections of a still further modified end stop before and after securin of the coupling clamp.
  • Fig. 12 is a plan view of the two parts of the end stop according to'Fig. 2 without the coupling clamp.
  • uniting the two tapes at one end of the stringers comprises two parts which are each secured to one tape by die-casting and coupled to "each other by means of a clamp inserted in the two parts.
  • the clamp for changing a slider only the clamp must be removed from the two parts of the end stop, while the two parts themselves According to theinvention theend stop forpling sockets formed as grooves.
  • Fig. 1 is a plan view of a part of a fastener
  • Fig. 4 is a transverse section through the end i stop along the line'IV-"'IV of Fig. 2.
  • Fig. 13 is a similar View of the two parts of the end stop from the opposite side.
  • Figs. 14 and 15 show a fastener element seen from two opposite sides.
  • the separable fastener shown in Figs. 1 to 5 comprises fastener element supporting tapes I and 2 having and edge head 3 to which the fastener elements 4 are directly secured by means of die-casting or pressure casting.
  • an end stop S formed oftwo separate parts 5 and 6 which consist of the same material as the fastener elements 4. These parts 5 and 6 are die-cast on the tapes I and 2 in the same casting operation together with the elements 4.
  • the fastener elements and the end stop can consist of metal, such as cast zinc, or of a thermoplastic material, as for exampleof a high molecular condensation'product such as known under the name of nylon, or the like.
  • the fastener elements 4 comprise a coupling head which is provided on opposite sides with coupling projections formed as ribs and with cou- Referring to Figs. 2, 3, l4 and 15, the coupling head of the elements is provided on one side with two ribs 1 and 8 and with two grooves 9 and Ill, while the opposite side of the coupling head is provided with two ribs l l and I2 and with two grooves I3 and 14.
  • the ribs 8 and I! extend from one side face of the element to surfaces It and It, respectively, each of these surfaces being posi- ;;;tioned at substantially one half of the width of the element and parallel with the common plane of the two tapes I and 2.
  • the rib 1 extends from the opposite side of the element to a surface I?
  • the rib H extends from the same side of the element to the surface I 6.
  • the groove 53 extends through the same width as the rib ii from one side face of the element to the surface It, and the groove [4 extends from the opposite side face of the element to a surface it, also situated at substantially one half of the width of the element.
  • he two parts 5 and t of the end stop are also provided with interengaging projections and recesses which prevent a relative displacement of the two parts in longitudinal direction, and cooperatin surfaces extending parallel with the common plane of the two tapes 1 and 2 which prevent a relative displacement of the two parts at right angles to the said plane.
  • the part 5 of the end stop is provided with a projection 20 which extends from one side face of the part to a surface 25 situated substantially at one half the width of the part, which surface is parallel with the common plane of the two tapes i and 2.
  • This projection 2e penetrates into a recess 22 of the part is which also extends from one side face of the part to a surface 23, which surface is situated substantially at one half of the width of the part and is parallel with the common plane of the two tapes.
  • the part 5 also is provided with a similarly positioned surface.
  • a projection '25 extends from this surface 2 to one side face of the part, and a recess 26 extends from the surface 2 1 A towards the opposite side until the other side face of the part.
  • a further surface 27 of the part 5 extends at substantially one half of the width of the part and parallel with the common plane of the two tapes i and 2. This surface 2'! forms one side of a projection 28 and one side of a recess 23.
  • the joined parts 5 and 5 of the end stop are coupled by a U-shaped metallic clamp 30.
  • the two branches 3% of the clamp penetrate through slots 3i and 32 provided at opposite side faces of the two joined parts, while the central portion 33 of the clamp is partially sunk in recesses 34 and 35 provided on one face of the two parts 5 and 5.
  • the clamp is inserted with its two branches into the slots 31 and 32, the branches being stuck through the tapes I and 2.
  • the branches of the clamp are slightly longer than the height of the two parts 5 and 6 of the end stop and after insertion into the slots 31 and 32 the projecting ends of the branches are upset or riveted in order to obtain a rigid connection between the clamp and the two par-ts '5 and 6.
  • the upsetting of the ends of the clamp produces a compression of the material of the parts 5 and 6 as shown in Fig. 4, so that the upset or riveted ends of the clamp overlie the edges of the parts 5 and 8 and firmly secure the clamp to the'two parts. These latter cannot separate any more and remain in their interengaged position.
  • the central portion 33 of the clamp 30 projecting beyond the outer face of the two parts 5 and 6 serves as stop for limiting the movement of the slider H], as shown in Fig. 1. Owing to this projecting clamp the slider cannot be lowered so far that the wedge portion 36 of the slider abuts against the end stop, or that the two parts 5 and 5 of the end stop are urged into the diverging guide passages of the slider; accordingly the two parts 5 and 6 are not subjected to any effort tending to separate them. In this manner, the clamp 30 itself is never subjected to any considerable stress, since its purpose is only to hold the two "parts 5 and '6 together, but these parts are not subjected to any effort tending to pull them out of engagement with each other.
  • the clamp When anew slider is to be engaged on the stringers of the fastener, the clamp can be removed from engagement with the two parts 5 and t 'by means of an appropriate tool. Then the old slider can be pulled off from the stringers and a new one can be engaged thereon without requiring to remove the end stop members -5 and 6 from the tapes 1 and 2, which would be impossible with the members die-cast directly on the tapes.
  • the part 6 of the end stop -on the tape 2 has its side facing the last fastener element 4 provided with'coupling ribs 1 and 8, and with coupling grooves 9 and 10, like one side of the coupling head of the fastener elements 4.
  • the ribs 1 and -'8 of the part 6 engage with the grooves l3 and [4 of the last fastener element '4 on the tape 1, and the ribs l1 and I2 of this element-"engage with the grooves 9 and I 0 of the part 6.
  • the upper 'open ends of the stringers are each provided with an end stop -40 which is also die-cast 'on the tapes I and 2 in the same casting operation together with the fastener elements '4 and the lower end stop 5 and 6.
  • the two end stops 40 have a length equal to the distance 'between two successive fastener elements, and for aesthetical reasons, the opposite side faces of the two stops '65 are formed with'the outer contour of two fastener elements which are rigidly connected by a central web 4
  • These stops 4B limit the upward movement of the slider, since they abut against each other int-he interiorof the slider and can accordingly not :pass out of the guide channel thereof.
  • the parts 5 and B are provided with notches 31 into which the material of the clamp ends can penetrate when these ends are upset, so as to produce a firm connection between the clamp and the two parts 5 and 6.
  • the branches of the clamp 3% are not passed through slots in the outer faces of the two parts of the end stop, but through tapering holes 38 provided in the two parts 5 and 9.
  • these parts consist of thermoplastic material, this latter is compressed upon forcing the branches of the clamp into the holes 38 of decreasing diameter, thus producing a frictional engagement between the clamp and the two parts.
  • the ends of the branches of the clamp are riveted as shown in Fig. 9.
  • the end stops 5 and t are made of cast zinc.
  • the holes for insertion of the clamp are cylindrical and formed with enlarged ends 33 into which the ends of the branches can be riveted.
  • the central web of the clamp is entirely sunk into the recesses 34 and 35 of the parts 5 and E, and accordingly does not act as limiting abutment for the movement of the slider. This latter is stopped by abutment of the wedge 36 against the end stop members 5 and 6.
  • the advantages of the described fastener are that the stringers can be cast together with the end stops on both ends thereof by a single casting operation in the same die and the two part end stop 5, 6 allows to readily exchange a slider for another one. Further, when the fastener elements and the end stop members consist of thermoplastic material, the coloring of the fastener elements and of the end stop member is absolutely identical, since they are cast simultaneously in a single operation and accordingly from the same supply of material.
  • the removable part is in the form of a U- shaped member having opposite legs and a base, the coupling members having exterior grooves for receiving said legs and base with said U-shaped member in embracing relation to said coupling members, with said base extending across said coupling members and said legs lying at those sides of said coupling members which are remote from each other, the terminal portions of said legs extending inwardly toward each other at the sides of said coupling members opposite said base for engaging said coupling members for securing said U-shaped member in assembled relation therewith.
  • each of the coupling members is formed with a perforation
  • the removable part is in the form of a U-shaped member having opposite legs received in said perforations.
