Definitions

  • the present invention relates to an improved fastener or zipper wherein both of its rows of coupling elements are completely separable from one another due to uncoupling terminal members seated at each row of coupling elements when a fastener slider moves into its open position. Furthermore, the separation movement takes place transverse to the direction of movement of the slider in the plane of the breadth of the fastener and brings out of engagement projections of both terminal members which mutually support themselves in this direction of movement, and whereby the terminal member detachable from the terminal member guiding the slider is moved through an associated lateral slot of the aforesaid fastener slider.
  • fasteners provided with rows of coupling elements completely separable from one another, in which the terminal member of one row of coupling elements is brought into the fastener slider located in the open position from the wide slider end and to a sleeve seated at the other row of coupling elements, to provide the confronting narrow sides of the terminal members with at least one, preferably a plurality of teeth which, during their tilting towards one another brought about by the movement of the slider in the closing direction engage one another and should bring about an effective locking lengthwise and transversely.
  • Such type fasteners also require careful handling if operational malfunctions are to be prevented.
  • terminal members mounted in front of the locking members carry the rows of coupling ele ments, of which the one, during effecting the connection, is moved through the associated side slot of the slider.
  • a carrier or support extending in front of the terminal members and which exhibits plugs or pins over which should engage eyelets applied at the bands.
  • a further important object of the present invention resides in the provision of an improved separable fastener which is relatively simple in construction, easy and economical to manufacture, reliable in operation and easy to handle so that the danger of malfunctioning or in operativeness is practically eliminated.
  • the mutual support of both of the terminal members directed away from the rows of coupling elements is constructed in the form of a guide or socket support releasable or disconnectable towards the side turned away from the rows of coupling elements and which pivotally guides a terminal member through the associated side slot of the fastener slider.
  • a guide or socket support releasable or disconnectable towards the side turned away from the rows of coupling elements and which pivotally guides a terminal member through the associated side slot of the fastener slider.
  • the arrangement can, thus, be readily selected in such a manner that, the pivoting-in can only then take place when the fastener slider assumes the required longitudinal or lengthwise position at the rows of coupling elements guiding it, that is, assumes the terminal position. If this should not occur then a stop or impact surface or the like can prevent the pivoting-in of the terminal member which is to be brought into the slider.
  • the socket support guarantees that upon displacement of the slider in the closing direction the lengthwise position of the terminal member introduced into the slider can no longer change. The support is, therefore, already given prior to the time that the fastener slider is moved in the sense of closing. Also, in this regard particular attention is not necessary during handling of the fastener.
  • the invention can be realized in a number of different ways. It is particularly advantageous to provide the terminal member which is pivotable with respect to the terminal member supporting the fastener slider at the end of the row of coupling elements with a projection extending past the width of the lateral or side slot of the fastener slider, the path of movement of which during pivoting of the terminal member lies in front of the frontal end of the fastener slider at the side of the row of coupling elements. Then it is possible to employ for the fastener a fastener slider of the standard type, whereby there further exists the security that the slider during pivoting-in and pivoting-out assumes the necessary lengthwise position at the row of coupling elements supporting it, because on the other hand the previously mentioned projection would prevent such pivoting-in and pivoting-out.
  • the projection forms the first coupling element of the associated row of coupling elements.
  • the terminal elements or members provided for the inventive fastener can, moreover, be configured in different manners. Particularly advantageous is a construction in which the terminal member supporting the slider in the terminal region turned away from the rows of coupling elements carries a bifurcated or forked extension forming the guide or socket support and the pivotable terminal element or member carries a projection provided with hearing pins engaging between the bifurcated arms of the socket support.
  • the terminal member supporting the slider in the terminal region turned away from the rows of coupling elements carries a bifurcated or forked extension forming the guide or socket support and the pivotable terminal element or member carries a projection provided with hearing pins engaging between the bifurcated arms of the socket support.
  • the terminal member arrangement in the position ready for separation and connection lies essentially within the fastener slider which has moyed into the open position, it is necessary to construct the terminal member of that row of coupling elements which guides the fastener slider such that it can accommodate itself to its form and that of its guide channel respectively. Additionally, it is recommended to divide such terminal member into a support element and a guide element pivotable with respect to the support element in the plane of the breadth of the fastener.
  • the arrangement is, thus, advantageously selected in such a manner that the frontal surface of the guide element at the end of the row of coupling elements forms a supporting or bearing surface for the already mentioned projection, preferably constructed as a coupling element, of the terminal member which can pivot-in and pivot-out.
  • the guide element is provided with guide surfaces embracing the guide ledges limiting or bounding the associated side slot of the fastening slider, in order to guarantee that during displacement of the slider upon the row of coupling elements guiding it, such always is reliably movable into the terminal position necessary for receiving the other terminal element, without thereby requiring any special attention.
  • the support element and the guide element arranged in front of the aforesaid support element can each independently be connected behind one another upon the relevant fastener carrier band.
  • the already mentioned direct lengthwise coupling of the support element with the guide element can be formed in a number of different ways.
  • the support element With the preferably nonmetallic terminal members injection molded onto the fastener hands it is recommendable to manufacture the support element with a projection which with subsequent injection molding of the guide element is embedded therein.
  • the projection then provides a reliable lengthwise connection which, on account of the flexibility of the injection moldable material coming under consideration for such purposes, provides the necessary additional relatively small mobility.

  • the stop portion 21 provided with a stop or arresting surface for the slider moved into the open position of the fastener, forms a shoulder or lug 22 extending past the longitudinal centrai plane of the closed fastener which is bifurcated parallel to the plane of the breadth of the carrier band 11, and in each bifurcated arm 22a forms a so-called guide or socket support 23.
  • An extension or shoulder 24 providing a hearing or support surface extends into the space bounded by both of the flanges formed by the bifurcation, such shoulder 24 following a recess 25 serving for further lengthwise support.
  • the support element 18 carries an extension or shoulder 26 above the recess 25 which cooperates with the guide element 19 which will hereinafter be described.
  • the support element 18 at both sides of the roll or bead 12 of the carrier tape or band 11 is provided with a respective neck or throat 27 transforming into a larger head 28.
  • the head 28 is embedded in the guide element 19.
  • This guide element 19 likewise spans the closure or carrier band 11 including its marginal bead 12 and partially extends past such.
  • the guide element 19 carries at both of its breadth faces or sides bearing against the carrier band 11 a respective channelor trough-like guide rail 29 which engages at both sides the confronting edges of the flanges 15b of the slider 15.
  • the guide element 19 For the purpose of supporting the guide element 19 with respect to the support element 18 there serves, on the one hand, the already-mentioned shoulder or extension 26 of the support element 18 and, on the other hand, a cam or dog 30 which engages in an appropriately configured groove or recess 30a of the support element 18.
  • the guide element 19 can pivot in clockwise direction about the neck 27 while utilizing the elasticity of the same and out of the position illustrated in FIGURE 3, in order to accommodate itself to the slider 15 which has moved into the open position.

  • the terminal member or element 16 particularly illustrated in FIGURES 5 and 6 only extends a small amount past the width of the associated band 10. Such is cutaway at its lower portion at the side of the marginal head 12.
  • the terminal member 16 incorporates a rearward portion bearing against both of the breadth faces of the band 10 and corresponds in thickness to that of the upper region of the already described support element 18 and the guide element 19.
  • the rearward portion 35 carries a thinner edge or flange portion 36 which likewise bears against both of the breadth faces of the band 10.
  • the narrow side of the edge portion 36 is arranged and configured in accordance with the projections in the bifurcated regions of the support element 18 and the guide element 19 respectively; and includes a projection 36a that seats in the recess 25 of support 18, whereby the terminal elements 16 and 17 mutually support each other in the direction of movement of the slider 15.
