Definitions

  • the invention concerns a zipper comprising two members provided with ribbons, the zipper being closed by pressing the members together and opened by bringing the members apart, or lby using a lock which by drawing in one direction -brings the members together and by drawing in the other direction brings the members apart.
  • Such zippers are known where the inner edge of the ribbon of both members are provided with metal hooks in succession at certain intervals. These hooks are r-unning zigzag with respect to each other in the two members one side surface of the part extending from the edge of the ribbons is provided with a projection and the other side surface is provided with a corresponding depression.
  • both members hook into each other in such a way that the projection of a hook on one member always goes into the depression of a hook on the other member.
  • such zippers have many marked disadvantages. Thus, they may open up quite easily when subjected to tension in the transverse direction, especially if the Zipper hooks are worn from use.
  • Such zippers are also known where the individual clos- Aing elements of both members, the so-called male and female elements, are bent from narrow-thin metal strips.
  • the strip is bent to a loop-shaped head and to opposite sides after the neckportion, and then inwardly to attach the element to the ribbon to form a run of closing elements.
  • the female elements again are made in such a way that the lower middle portion of the element facing the ribbon is plane and then both ends of it are first bent upwardly and then inwardly, so that a central opening for the head of the punch element is formed.
  • each female element may have a punched point for fixing the elements to the ribbon to form a run of closing elements.
  • the zipper made up of the above-mentioned elements is closed by pressing the heads of the punch elements one after another into the central openings of the matrice elements and the zipper is opened by the opposite move.
  • both members comprise a thin uniform strip of sheet metal, provided with transversal slits or cuts in succession at certain intervals to accomplish flexiblity, which strip is bent to an openlooplike ridge viewed in cross-section, extending over its entire length, at which in closing the zipper the ridge of one member can be pressed into the ridge of the other member through the open neck portion, thus locking the ridges to each other.
  • the ridge of both members is located substantially at the centre of the strip at which one edge or both edges of the strip are provided with projections, teeth, or the like, for fastening the ribbons, such slits or cuts being provided at least at each tooth.
  • both members comprise a uniform metal strip catching to each other no such parts exist, e.g. hooks, which are able to take a position that would make locking impossible. Due to the uniform metal strips the members are quite stiff and thus provide support for the edges of the opening to be closed, for instance, when the zipper is fixed to the opening of a pocket, or to the leg of a shoe. Nevertheless, the zipper is flexible enough due to the transversal slits or cuts provided the metal strip which make up both members.
  • the zipper, according to the invention is also extremely reliable and will not open even when subjected to transverse tension. Furthermore, the manufacture is easy and simple, and likewise the fixing of the metal strips to the ribbons. On this account the zipper will be cheaper than those previously known.
  • FIG. l presents from above a portion of the female member of the zipper, according to a first working example of the invention, partially fastened to the ribbon of the Zipper
  • FIG. 2 presents a cross-section of FIGURE l taken on the line II-II
  • FIG. 3 presents a cross-section of the zipper with the male and female members in a closed position
  • FIG. 4 presents from above a portion of the metal strip used for making the members of the zipper according to a second working example
  • FIG. 5 presents from above a portion of the metal strip used for making the members of the zipper according to a third working example
  • FIG. 6 presents from above a member, according to a fourth working example, before fastening to the ribbon,
  • FIG. 7 presents a section through the slit of a zipper made from the metal strip presented in FIGURE 5 or 6, in closed position and provided with ribbons,
  • FIG. 8 presents a cross-section through the slit of the zipper according to a fifth Working example, in closed position and provided with ribbons,
  • FIG. 9 presents a cross-section of the zipper according to FIG. 7 in closed position and fastened to the counter part, and FIG. 10 presents in the same Way as FIG. 9
  • the zipper according to the invention is only a few millimeters wide and comprises a female member including a ribbon, male member likewise including a ribbon, and possibly a lock for closing and opening the zipper.
  • Both halves are preferably made from a long, thin, and narrow strip of steel, copper-tin or copper nickel alloy, which is cut to pieces corresponding to the desired length of the zipper.
  • projections or teeth 2 are punched into one edge of the metal strip 1, as well as transversal slits 3 into the centre of the strip at a distance from each other. Furthermore, the edge of the strip opposite to the teeth 2 is provided with a bend 18.
  • the outer half 4 is bent longitudinally in such a way that a ridge 5 is formed along the centre of the strip, the cross-section of which is shaped as an open loop. This shape of the ridge reminds of the cross-section of a pressbutton, i.e., a loop with a neck-portion and a main portion.
  • the ridge 5 of the loop in the case presented is not symmetrically located in relation to the centre-line of the neck-portion 6, but its outer edge is somewhat larger than the inner edge.
  • the ridge 5 may also be symmetrical.
  • An edge-portion 7 covering the entire length of the member remains between the neck-portion 6 and the teeth.
  • the female-half 4 is usually fastened to a ribbon 8 of cloth by means of the teeth 2, which are clinched on the other side of the ribbon, so that the clinched toothends almost entirely will surround the edge of the ribbon, as shown in FIG. 2.
  • the shape of the zipper male member 9 almost corresponds to that of the female member 4, it is made of a similar metal strip and the outer edge is fastened to the ribbon 12 in the same manner as the female member 4.
  • the ridge 10 at the centre is also provided with perforated or punched slits or cuts over the entire length. It differs from the female member 4 in that a cross-sectional view discloses that the ridge 5 of the loop is smaller, the neckportion is narrower and longer and the inner edge provided with the bend 18a is longer than corresponding parts of the loop of the female member 4, so that the loop of the male member 9 lits into that of the female member. Otherwise, these loops chiefly correspond to each other as far as shape is concerned and both of them may be symmetrical or similarly unsymmetrical in relation to the vertical centre-line of the neck-portion.
  • the zipper is now closed in which position the edge of the female member 4 provided with the bend 18 rests on top of the edge of the male member 9 on the ribbon 12 side, and the edge of the male member provided with the bend 18a is situated under the clinched side of the male member. Opening of the zipper is carried out by drawing the lock in the opposite direction, so that the members are released from each other.
  • both halves are made from the metal strip 1 presented in FIGURE 4 by bending in the manner described above.
  • the thing that differs in comparison with the metal strip according to FIGURE l is that the slit 3 punched at each tooth 2 extends about to the edge on the toothside of the strip 1 and in addition, that the other end of the slit 3a punched between every two teeth 2 extends open to the edge between the teeth.
  • the opposite ends of all slits 3 and 3a relative to the teeth extend to a given distance from the edge of the strip 1, so that an edging is obtained which is formed to a bend 18.
  • Both side edges of the metal strip 1 according to FIG- URE 5, used for making the members in accordance with one working example of the invention, are provided with teeth 2 punched at a distance from cach other. These are always situated on one edge between the teeth on the other edge, i.e., they are situated in a zig-zag to each other on the opposite edges of the metal strip.
  • a transversal slit 3 is punched into the metal strip 1 at the middle of each tooth 2, which slit extends from within the tooth to the opposite edge of the strip, and is narrowed at the end of the tooth.
  • FIG. 6 presents from above the female member of the Zipper according to one working example of the invention.
  • the metal strip 1 making up the members differs from the strip according to FIG. 5 in that the teeth 2 on the opposite edges are situated against each other, and that the transversal slits 3 at the teeth only reach to the edges of the strip 1, or somewhat beyond the edges.
  • the zipper of which a cross-sectional view is presented in FIG. 7 can be made from metal strips 1 according to FIGURES 5 and 6.
  • the female member 4 of the Zipper is made by bending a ridge 5 along the centre of the strip with a cross-section forming of an open loop the neckportion of which extending to the plane edge-portion 7 of the strip 1.
  • the ridge 5 is not symmetrical relative to the central vertical plane.
  • the left side of the ridge in FIG. 2 is slightly longer than the right side although the ridge may also be symmetrical. According to FIG.
  • a ribbon 8 is fixed by means of the teeth 2 to both edges of the female member 4 of the above-mentioned zipper in such a way that the teeth first pass through the ribbon from above and then distance along its lower surface so that the end of the tooth 2 is clinched around the edge of the ribbon.
  • the male member 9 is made from the metal strip 1 according to FIG. 5 in the same manner as the female member 4.
  • the male member 9 is also provided with a longitudinal, the cross-section of which is chiefly of the same shape as the ridge 5 of the female member 4, but still small enough to fit into the ridge S of the female member :t in order to close the zipper.
  • the neckportion 11 is longer and thinner than the corresponding part 6 of the female member 4 because it must extend below the outer half for attachment to ribbon 12 by means of the teeth 2a at both edges, i.e., along two rows of teeth.
  • the ribbons may be fastened to the edges of the female member in the manner shown in FIGURES 8 and l0, i.e. the teeth 2 pass through the ribbon from below.
  • the zipper made from the metal strip according to FIG. 5 is extremely elastic in the direction vertical to its plane. A zipper like this can be closed simply by pressing the ridge 5 of the female member over the ridge 9 of the male member, or by pushing the ridge of the male member into that of the female members, and it can be opened by detaching the members from each other.
  • the zipper also may be provided with a suitable lock, which closes the zipper on drawing in one direction and opens it on drawing in the other direction.
  • a zipper presented as a cross-section in FIG. 8 can be made from metal strips 1 according to FIGURES 5 and 6.
  • the ridge S of the outer half 4l of this zipper is bent in such a way, that its upper surface is plane and the edges are about triangular in shape.
  • the member 4 is xed to the ribbon 8 in such a way that the edge of the ribbon reaches to the neck-portion 6 Where the teeth 2 pass through the ribbon from below and the ends of the teeth are bent to the upper surface of the ribbon.
  • a narrow ribbon 13 is fastened to the other edge of the female member 4 by means of teeth 2.
  • the upper surface of the ridge 1G of the male member 8 is also plane but the edges are bent.
  • counting from the vertical centre-line is wider than the right side.
  • edges of the ridge 5 are covering the teeth 2 entirely so that only the plane upper surface and the edges of the female member ridge of the zipper are visible when fixed in place and in the closed position.
  • the lock 14 to be used ⁇ for a zipper of this kind has a cross-section which chiefly corresponds to the cross-section of the ridge 5 of the female member 4, while the edges of the look glide along the outer edges of the ridge 5 on closing and opening the zipper.
  • one ribbon 8 of the female member of the zipper according to FIG. 7 is turned for instance, around the edge of the seam 15 of a blouse and is fixed at point 16 by sewing.
  • the other ribbon 8 of the outer half is fixed to the salme seam 15 at point 17 by sewing.
  • the ribbon 12 of the male member 9' of the zipper is sewed to the other seam of the blouse in such a way that the seams will be situated opposite each other.
  • the working example according to FIG. is otherwise similar to that presented in FIG. 5 except that the ribbons 8 are joined to the female member 4 of the zipper by means of teeth 2 which pass through the ribbons from below and then along the upper surface to and around the edge lof the ribbon 8i. In this way the zipper will be flatter.
  • teeth or projections may exist on one edge (FIGS. 1-3) or on both edges of each member, either at a distance from each other or joining each other at the base.
  • teeth or projections are provided only on one edge (FIG. 4) of the metal strip, or if they are situated zigzag on opposite edges (FIGS. 5-8), every two adjacent teeth or projections on the same edge may be situated either at a distance from the slit extending open to this edge, or the base of adjacent teeth may unite with the edges of the open slits.
  • a zipper for connecting the edges of adjacent sheets of material comprising:
  • a resilient female member carried by the edge of one of the sheets to be connected, said member extending the length thereof and having a transversely intermediate portion formed into an upwardly projecting ridge, said ridge forming a longitudinal channel having a reduced width neck portion adjacent the mouth thereof, and
  • said male and female members having a plurality of spaced slits extending transversely across the width of said ridge.
  • each of said slits located transversely of one of said teeth extends into one of said teeth and wherein each of said slits located midway between said teeth is eut through the longitudinal edge of said member provided with said teeth.
