Definitions

  • An ornamented plastic zipper construction comprising integrally molded plastic elements having front and rear portions with the'side edges of the rear portion being undulated or of zigzag configuration whereby to define outwardly extending teeth and inwardly extending recesses, said teeth extending outwardly of the adjacent side edge of the front portion, and said recesses extending inwardly thereof, whereby when said zipper elements are interlocked, the teeth of one element extend into the recesses of the next-adjacent elements, the outermost portion of saidteeth underlying the front portions of the adjacent elements whereby there is a simultaneous interlocking and overlapping between adjacent elements so as to resist pull-apart, shear, and flexural forces on the closed zipper.
  • a further'feature of the present invention resides in the fact that adjacent zipper elements, when interlocked, form a straight line with the abutting edges of adjacent elements in close adjacency to each other.
  • the present invention relates generally to a plastic zipper construction, and particularly a plastic zipper of the ornamented type, such as are frequently used in womens apparel and the like or wherever the zipper is to simultaneously provide an ornamental function as well as the conventional fastening function.
  • Plastic zippers of this type may be ornamented on the outer surfaces of their front portions by the mounting of ornamental stones, such as rhinestones and the like, thereon; and such zippers may be used in place of buttons and buttonholes, hooks and eyes, and the like normally found on articles of womens apparel.
  • the interlocking zip-- per elements are arranged in two rows and secured alternately on the opposite edges of the material to be secured, with each element having a ball-like projection extending from one side edge thereof and a complementary socket or recess located at the opposite side edge thereof; whereby when the elements are interlocked, the ball-like projection of one element engages within the complementary socket or recess of the nextadjacentelement to maintain the zipper in closed or interlocked condition.
  • Another object of this invention is the provision of an ornamented zipper construction of the character described wherein each zipper element, although being integrally molded, comprises distinct front and rear portions, with the functional interlocking parts located entirely in the rear portions, whereby the rear portions may be molded in one cavity, and the front portions in the other cavity of a two-part mold, thus permitting the same rear mold tobe used with different front molds so as to permit zippers having different ornamental front portions to be readily and easily manufactured.
  • a further object is the provision of a zipper construction of the character described that is relatively simple and economically feasible to manufacture, but which nevertheless is relatively durable and effective in use.
  • FIG. 1 is a front elevational view of a zipper construction comprising the present invention with the zipper shown in partially closed position;
  • FIG. 2 is a rear elevational view thereof
  • FIG. 3 is a side elevationalview of one of the zipper elements per se
  • FIGS. 3, 5 and 6 there is shown generally at 10 a zipper element of one-piece, unitary molded construction. More specifically, the element 10 is injection molded of any suitable plastic material having the required strength characteristicsand being capable of withstanding the usual degreasing solvents. For example,
  • portion 12 is preferably of a rectangular configuration at parting line 34, the top or front part of portion 12 may be rounded or otherwise configured, as desired.
  • the front surface 16 of front portion 12 may be provided with a centrally positioned recess, such as 18, in which may be mounted an ornamental stone 20 such as a rhinestone or the like.
  • the opposed side edges 22, inner edge 24, and outer edge 26 of portion 12 are all inclined or beveled outwardly from the surface 16, as will be seen most clearly in FIGS. 3 and 5.
  • Rear portion 14 of zipper element 10 has opposed side edges 28 of an undulating or zigzag-like configuration defining outwardly extending tooth portions 30 and inwardly extending recesses 32. It will specifically be noted, and this is of critical importance, that the outwardly extending tooth portions 30 extend outwardly a substantial distance beyond the flat parting line 34, which is the line of separation between front portion 12 and rear portion 14. Likewise, it will be noted that recesses 32 extend substantially inward of line 34, and said recesses are of a configuration generally complementary to the configuration of the tooth portions'30, both being of a somewhat V shape.
  • a generally circular 3 groove 36 is located adjacent the inner edge of element and has a slot 38 in communication therewith. At its opposite or outer edge, the element 10 is provided with a U-shaped groove 40, it being noted that both the groove 36 and the groove 40 extend from side to side of element 10.
  • FIGS. 1 and 2 there are shown a pair of fabric strips 42, each being provided along its inner edge with a pair of parallel cords 44, 46.
  • the strips 42 are adapted to be secured to the edges of a garment or article of apparel, all in a well-known manner, which edges are then adapted to be joined or united by the zipper construction shown.
  • the elements 10 are secured to the spaced strips 42 in spaced, staggered relation with the cord 46 received within groove 36.
  • the elements 10 are molded directly onto the strips 42, as is well known and conventional in the art.
  • a conventional slider 48 such as one having the onstruction shown in aforesaid U.S. Pat. No.
  • 3,028,647 may be manipulated to close and open the zipper in a well-known and conventional manner.
  • the outwardly extending teeth 30 of each element engage within the recesses 32 of the adjacent elements toeffect an interlock which will resist pull-apart forces on the closed zipper.
  • the outermost portion of teeth 30 actually extend'under the parting line or ledge 34 so as to partially underlie the front portion 12 of the adjacent element 10.
  • This overlapping relationship functions to resist both shear and flexural forces that may be normally encountered and which might otherwise result in advertent separation of adjacent elements.
  • it is the simultaneous interlocking and overlapping of adjacent elements that results in a zipper construction having the desired strength, but which nevertheless still has sufficient flexibility so as to be comfortable and effective in use; i
  • the element 10 is injection molded, and preferably in a two-part mold, the parting line of which is located at line 34, which preferably is located substantially midway of the thickness of the element 10.
  • the front portion 12 is molded in one cavity,'while the rear portion 14 is molded in a separate cavity.
  • different mold cavities may be substituted-for forming the front portions 12, which molds may easily be mated with the mold ,which forms rear portion 14, which latter mold, of
  • a zipper element for joining a pair of fastener strips comprising inner, outer and opposite side edges and having superimposed front and rear portions of different peripheral configurations, a first groove positioned substantially centrally of said inner edge and extending thereacross from side edge to side edge' for securement to an edge of one of said strips, a second groove of substantially the same size as said first groove positioned substantially centrally of said outer edge and extending thereacross from side edge to side edge for releasably receiving the edge of the other of said strips, said rear portion having generally undulating side edges defining outwardly extending teeth andiiiwardly extending recesses, said teeth extending outwardly beyond the adjacent front portionsideedge and said recesses extending inwardly thereof, said teeth and recesses being generally complementary in configuration and arranged so that when a pair of reversely extending elements are positioned side by side, theteeth of one element extend into the recess of the next element and underlie the front portion of said next element in order to maintain said elements interlocked against pull
  • a zipper construction comprising interlocking zipper elements in two rows and secured alternately on the opposing edges of the material to be fastened, said elements comprising members having superimposed front and rear portions of different peripheral configurations, said elements further having inner and outer edges and opposed side edges, means at said inner edges for effecting securement of said elements to their respective edges of material, means at said outer edges for releasably receiving the opposite material edge when said elements are interlocked, said rear portions having generally undulating side edges defining outwardly extending teeth and inwardly extending recesses, said teeth extending outwardly beyond the adja cent front portion side edge and said recesses extending inwardly thereof, whereby when said, elements are interlocked, the teeth of one element engage within the recesses of thenext-adjacent elements and at the same time underlie the front portion of said next-adjacent elments form a straight line, when viewed from front or ements, the side edges of adjacent interlocked elements rean being In substantially abutting relation, the mteren-
