Definitions

  • This invention relates to separable fasteners which can be made of metallic or thermoplastic materials. More particularly, the invention relates to stringers for slider operated separable fasteners of the type wherein two rows of fastener elements are interlocked and disengaged by the slider bending the rows in the planes thereof toward and away from each other.
  • This application is a division of my prior application Serial No. 480,463, flied March 25, 1943, now Patent 2,380,623, dated July 31, 1945.
  • each fastener element is provided with a stud forming an integral extension of the head portion element and by means of which the element is directly attached to the article to be provided with the separable fastener.
  • the elements are first strung on a carrier consisting of rigid material but which owing to its shape or feeble cross sectional area is rendered flexible, so as to obtain fastener stringers having the required flexibility for the operation of the usual slider producing engagement and disengagement of the cooperating elements.
  • the carrier can preferably consist of a thermoplastic material, such as high molecular condensation products, polyamides and the like, in the shape of threads, wires or bands, on which the fastener elements are longitudinally spaced.
  • Such carrier threads can be obtained by draw ing the material nearly to its limit of expansion, so that the threads do. not expand any more and the fastener elements fixed thereon always keep their correct spacing, while in transverse direction these threads are extremely flexible to allow an easy displacment of the slider along the stringers.

  • the connecting stud I of the head portion I of the fastener element is provided with a laterally open notch I! for the carrier thread I.
  • the connecting stud is provided on one side of the head portion I, while on the other side of this portion a guide surface I for the slider is protwo hooks II and II of the end portions II and II are axially displaced so that they do not prevent each other from penetrating into the material.
  • the width or cross sectional area of the connecting stud I is smaller than that of the fastener element so that shoulders I are formed between the connecting stud and the fastener element for guiding the usual operating slider I of the fastener.
  • the carrier I is inserted into a notch II provided in the lower portion of the head portion I laterally of the connecting stud I and then the projection II laterally of the notch is bent towards the carrier I and pressed against the latter so as to ensure a ilrm connection of the fastener element with the carrier.
  • the attachment of the fastener elements on the article II which is to be provided with the fastener is eflected in the same manner as in the example according to Figs. 1 to 3, by means of the end portions II and II of the connecting studs I. Guiding of the slider is obtained by means of shoulder surfaces I on both sides of the connecting stud I.
  • a notch II is provided in the middle of the rear end of the head portion, while the connecting stud I is disposed on one side of this portion.
  • the carrier thread I placed in the notch II is fixed to the fastener element by clamping the projection II down on the carrier.
  • a guiding surface I for the slider is disposed on one side of the head portion I.
  • the connecting stud I is again provided with two free end portions II and II which are clamped towards each other for attaching the stringer formed by the fastener elements and the carrier I to the article II, whereby the hooks II and II penetrate into the material of the article.

  • the edge portion of this latter is introduced between the end portions II and II which are then clamped towards each other so that the pointed ends II and I2 traverse the material of the article.
  • the fastener element represented in Figs. 16 and 17 is provided with a notch I1 in the connecting stud I for insertion of the carrier thread I which is clamped in the notch by pressing the two projections 58 of the material of the connecting stud against the carrier.
  • the stud I is provided with two end portions II and II which are spread apart before the fastener element is attached to an article.
  • the end portion II is provided with small prongs II, and the end portion II with corresponding conical holes II.
  • an edge portion of this latter is introduced between the two end portions II and II which are then pressed together so that the prongs II penetrate through the material of the article and into the holes 66 of the end portion II, where they are then riveted as shown in Fig. 17.
  • the carrier I is secured in a notch I! of the fastener element by pressing the projections II over the carrier inserted in the notch.
  • the connecting stud is provided with two free end portions I! and II, of which the portion I! has a hook-shaped pointed end II, while the portion II is provided with a recess 10.
  • an edge portion of the article is introduced between the spread apart end portions 61 and II and then these latter are clamped towards each other, so that the hook shaped end 89 penetrates through the material of thearticle 92 and into the recess 19 of the portion I, to engage behind the nose ll of this portion.
  • the head portion i of the fastener element is secured to a carrier 9 inserted into a notch provided in the element.
  • the connecting stud 4 is provided with two free end portions 13 and 14.
  • the end portion 13 forms an extension of the connecting stud I and is directed according to the vertical axis of the fastener element, while the end portion 14 is spread laterally.
