  • This invention relates generally to slide fasteners and more specifically to a cooperative pair of top stops for arresting the movement of a slider in a fastener closing direction on a pair of fastener stringers. Even more specifically, the invention is directed to top stops for use in a slide fastener of the type having a continuous coupling
  • top stops for slide fasteners
  • the endmost fastener element on each stringer tape is fused and deformed into such shape as to arrest the movement of the slider. It is also known to fuse film-like piecesof thermoplastic material onto the respective stringer tapes. generally in V-shaped arrangement.
  • top stops are mostly not of sufficient strength to resist the thrust of the slider that acts repeatedly thereon in the use of the slide fastener. Such top stops are therefore relatively easy to be bro ken or otherwise rendered inoperable or are not so endurable as they are required to be.
  • an object of this invention to provide improved top stops which are so constructed and arranged as to well withstand the thrust of the slider acting thereon throughout the prolonged period of use of the slide fastener.
  • Another object of the invention is to provide top stops so constructed and arranged that the slider can be positively guided to its predetermined topmost position on the pair of fastener stringers.
  • top stops according to the invention are intended for use in a slide fastener of the type having a continuous coupling element which is made of a synthetic resin filament and which is arranged on one surface of each stringer tape along its longitudinal edge lying adjacent the other tape.
  • the continuous coupling element is so shaped as to provide a longitudinal row of coupling heads adapted to engage between the similar coupling heads of the complementary coupling element. and a longitudinal row of connective portions remote from the coupling heads.
  • top stops which are of synthetic resin material, are fused to the respective stringer tapes at the upper extremities of the continuous coupling elements.
  • Each top stop integrally comprises a stop portion against which the slider abuts at the end of its fastener closing movement, and a guide portion which. as the slider draws near the end of the fastener closing movement.
  • FIG. I is a partial top plan view of a slide fastener incorporating a preferred form of the top stops according to the invention, in which the slider is shown in its topmost position on the pair of fastener stringers and in which the front wing of the slider is cut away to clearly reveal the relations between the top stops. the fastener stringers and the slider;
  • FIG. 2 is a perspective view of one of the fastener stringers shown in FIG. I;
  • FIG. 3 is a sectional view taken along the plane of line III-III in FIG/I.
  • FIG. I best illustrates the general organization of a slide fastener for which the improved top stops of this invention are particularly well adapted.”
  • lhe illustrated slide fastener comprises a pair of stringers I0 and a slider II.
  • Each stringer It has a tape I2 with a continuous coupling element 13 arranged along one of its longitudinal edges opposed to the corresponding edge of the other stringer tape.
  • Each continuous coupling element I3 is substantially in the form of a coil or helix of a synthetic resin filament and is secured to one surface only of each stringer tape 12 by a line of stitching 1.4 with the aid of a core member 15 extending longitudinally.throughthe coupling element.
  • the continuous coupling element 13 comprises a series of uniformly intercsticcd coupling heads arranged along one of the longitudinal edges thereof for engagement between the similar coupling heads of the complementary coupling element, and a series of connective portions 17 arranged along the other longitudinal edge of the coupling element.
  • the slider 11 slidable along the pair of continuous coupling elements 13 in either direction to open or. close the fastener, has a body comprising a front wing 18 and a back w ing I9 which are interconnected by a web 20, as will be seen by referring also to FIG. 3.
  • the wings I8 and I9 and the web 20 define the usual Y shaped guide channel through which the coupling cle ments I3 are adapted to pass.
  • the front wing I8 has a pair,of side flanges 2
  • the side flanges 21 include divergent portions 22 adjacent the .llarcd top end 23 of the slider body and parallel portions 24 adjacent the contracted bottom end 25 of the slider body.
  • a cooperative pair of structurally similar top stops 26 are fixedly mounted on the respective stringers 10 at or ad;
  • each top stop 26 a chip orsheet of nylon or like synthetic resin material. may be placed in the specified position on each stringer 10. so as to partly overlie several of the connective portions 17. including the topmost one, of the continuous coupling element [3.
  • the chip or the like is then fuscdunder application of pressure. as by the known high-frequency or ultrasonic welding techniques. in such a fashion that the resulting top stop 26 envelops and' unites integral with the several connective portions l7 of the coupling element.
  • Each top stop 26 thusvmolded and fused to the stringer tape is. formed. at the same time. with a guide portion 27. a stop portion 28 and a flat base por tion 29.
  • the guide portion 27 is substantially in the shape of a right-angled trianglewhen seen in a plan view as shown in FIG. I. with a sloping guide edge or surface 30 located remote from the element carrying edge of the stringer tape 12. and generally tapers in a direction away from the top end of the fastener.
  • the stop portion 28 is substantially rectangular in shape. is greater in height and in a dimension in the transverse direction ofth'e tape (see FIG. 2). and is located immediately on the fastener top-end side of the guide portion 27. mentioned previously.
  • these guide portion 27 and stop portion 28 of each top stop 26 envelop and unite integralwith thc several connective portions 17. including the topmost one. of the corresponding continuous coupling clement l3 W lt ⁇ vill be observed from a consideration ofFlGS. l andy2 that at least thc topmost coupling head of each continuous coupling element 13. which head is transversely aligned with the stop portion 28 of each top stop 26. is removed from the coupling element. It is unne"es s' ry to remove the coupling heads transversely aligned with the guide portions 27 of the top stops.
  • the slider ll slides along the continuous coupling elements 13 on its fastener closing movement to the topmost position on the pair ofstringers 'lil.
  • the guide portions 27 of the topstops 26 first enterfrclatively into the slider body through its flared top end 23.
  • the slider 11 can be positively guided to its predetermined topmost position shown in Fl(iS. l and 3. in which position the top edges oftlie side flanges 2
  • stop portions 28 of the top stops 26 are by far the most conspicuous members on the stringer tapes 12 because oftheir extra height and transverse dimension. their positions on the stringer tapes can be visually ascertained in a simple and accurate manner. so that a border line 28: extending transversely and defined between the guide portion 27 and the stop portion 28 of each top stop 26 serves as a reference point in correctly positioning the top stop 26 ⁇ vithrespect to a preceding or first coupling .element 13a on each of the stringer tapes in the assem- 'bling process of slide fasteners.
  • a slide fastener of the type comprising a pair of stringer tapes each having a continuous coupling element arranged on one surface thereof so as to extend along its one longitudinal edge adjacent the other stringer tape.
  • said eoupling'elcment being made of a synthetic resin filament and including a series of coupling heads arranged along one longitudinal edge of the coupling element and a series of connective portions arranged along the other longitudinal edge of the coupling element.
  • said coupling heads being adapted to engage between the similar coupling heads of the other coupling element.
  • a slider slidable along said coupling elements and including a body having a flared top end and a contracted bottom end.
  • said slider body ineluding a front wing and a back wing which are interconnected by a web located at said flared top end.
  • said front wing of said slider body having a pair of side flanges. the combination thereof with a pair oftop stops made of synthetic resin material and fused to said stringer tapes at the upper extremities of said coupling elements. respectively.
  • each of said top stops integrally comprising a stop portion against which the top edge of one of said side flanges of said front wing abuts when said slider is moved along said continuous coupling ele ments to its predetermined topmost position on the slide fastener.
  • each top. stop being substantially rectangular in shape and being greater than said guide portion both in height and in a dimension in a transverse direction ofthe stringer tape. said stop portion and said guide portion of each top stop enveloping and uniting integral with several of said connective portions. including the topmost one. of the corresponding coupling element.
