Definitions

  • ABSTRACT A slider aligning device is disclosed for use in a separable slide fastener of the class comprising a pair of stringers having longitudinal rows of interfitting fastener elements on their opposed edges respectively, and a pair of sliders arranged reversely to each other on the rows of fastener elements for longitudinal movement therealong to engage and disengage the same.
  • the aligning device includes a pair of recesses formed inconspicuously at the contracted end of one of the sliders, and a pair of tongues formed correspondingly at the opposed contracted end of the other sliderf
  • the tongues are so shaped and sized as to fit neatly in the respective recesses when the contracted ends of the two sliders are brought into contact with each other, so that the sliders can be held in correct alignment during insertion or removal of a pin member at one end of one of the stringers into or out of the guide channels of the respective sliders.
  • the device is adaptable for a separable slide fastener of the type incorporating a box and pin coupling.
  • the box member has a projecting pin portion adapted to enter a groove or grooves formed internally of the slider, but this arrangement is unapplicable to the two-way type of separable fasteners.
  • Another object of the invention is to provide an aligning device of the character described, whereby the manipulation of the separable slide fasteners is materially simplified, particularly in connection with insertion or removal of a pin member on one of the fastener stringers into or out of a pair of sliders on the other stringer.
  • a further object of the invention is to provide an aligning device of the character described, which requires minimum modification in the shape or size of the sliders, such that the general appearance of the conventionally known sliders is substantially retained intact.
  • a still further object of the invention is to provide an aligning device of the character described, which is compact, inexpensive and endurable in construction and which permits the sliders to be correctly and securely aligned with each other over prolonged periods of use.
  • an aligning device for a separable slide fastener of the two-way type having a pair of sliders arranged reversely with respect to each other on rows of interlocking fastener elements arranged along the opposed edges of a pair of stringer tapes respectively.
  • the device comprises a pair of recesses formed at that end of one of the sliders disposed opposite to the other slider, in such a way that the recesses are substantially invisible from the outside of the slider, and a pair of tongues formed at the corresponding end of the other slider to be neatly received in the respective recesses, whereby the two sliders can be exactly aligned one with respect to the other.
  • FIG. 1 is a fragmentary perspective view of a separable slide fastener of the two-way type configured in accordance with the novel concepts of this invention
  • FIG. 2 is a fragmentary top plan view of the separable slide fastener of FIG. 1, in which the pull tabs are omitted and in which the pair of sliders are shown in their properly aligned position;
  • FIG. 3 is a side elevational view, partly in section, of the pair of sliders aligned as in FIG. 2;
  • FIG. 4 is a view similar to FIG. 2 which is explanatory of the positions which the respective sliders will assume when a pin member is about to be inserted into their guide channels;
  • FIG. 5 is a sectional view taken along the plane of line VV in FIG. 4;
  • FIG. 6 is also a sectional view taken along the plane of line VIVI in FIG. 2;
  • FIG. 7 is a fragmentary sectional view similar to FIG. 3 showing another preferred embodiment of the invention.
  • FIG. 8 is a fragmentary top plan view showing still another preferred embodiment of the invention.
  • FIG. 9 is a perspective view of the box member of a box and pin separable coupling constructed according to the concepts of the invention.
  • FIGS. 1 to 6 a separable slide fastener of the aforesaid two-way or double acting type incorporating the novel concepts of the invention.
  • the two-way separable fastener comprises a pair of stringer tapes and 11 carrying longitudinal rows of spaced-apart interlocking fastener elements 12 of any known or suitable type on their opposed beaded edges respectively.
  • each of the sliders 13 and 14 has a body portion comprising a pair of spaced-apart wings or plate members 15 and 16 having flanges 17 along their marginal edges and interconnected through an integral neck or web 18 at their flared end 19 so as to define a generally Y-shaped guide channel through the slider.
  • Such guide channels of the respective sliders are adapted to permit the rows of fastener elements 12 to be threaded therethrough for their engagement or disengagement.
  • Each of the sliders l3 and 14 is further provided with a longitudinally extending lug 20 on its top wing 15 to which there is pivotally and slidably attached a finger piece or pull tab 21 for use in manipulating the slider.
  • a pair of pin members 22 and 23 are attached to the opposed edges of the respective stringer tapes 10 and 11 at one end of the fastener.
  • the pin member 23 includes an integral stop portion 24 for limiting the movement of the slider 14 at the said one end of the fastener and for retaining the sliders 13 and 14 on the stringer tape 11 after it has been completely separated from the other stringer tape 10. It may be noted from FIGS. 2 and 3 that during insertion or removal of the pin member 22 on the stringer tape 10 into or out of the sliders l3 and 14, the contracted end 25 of the slider 13 is to be held in neat contact with a similar contracted end 26 of the other slider 14, so that the two sliders will be completely aligned with respect to each other.
  • the contracted end 26 of the other slider 14 has integral tongues 29 and 30 protruding from its top and bottom wings 15 and 16 respectively.
  • These tongues 29 and 30 correspond both in shape and size to the recesses 27 and 28, and as will be seen from FIG. 3, the inside surfaces of the tongues 29 and 30 are on the same planes as the inside surfaces of the respective top and bottom wings of the slider 14.
  • the tongues 29 and 30 of the slider 14 are to be neatly received in the respective recesses 27 and 28 of the slider 13 when the contracted ends 25 and 26 of the two sliders are brought into contact with each other, so that the sliders can be held in completely aligned relationship to each other.
  • the stringers of the fastener have been completely separated from each other and that the pin member 22 on the stringer tape 10 is now about to be inserted into the guide channels of the respective sliders 13 and 14 for joining the corresponding ends of the stringers together, as illustrated in FIG. 4.
  • the sliders 13 and 14 may not at first be aligned with respect to each other and may further be partly displaced from the plane of the stringer tape 11, as illustrated in FIGS. 4 and 5, even though the tongues 29 and 30 of the slider 14 may be partly received in the respective recesses 27 and 28 of the slider 13.
  • the pin member 22 can now be smoothly inserted into and through the guide channel of the slider 13 and further into the guide channel of the slider 14 until the pin member is properly positioned therein to permit the correct engagement of the fastener elements 12 upon movement of the slider 13 away from the slider 14.
  • both wings 15 and 16 of each of the sliders 13 and 14 are provided with their own recesses 27 and 28 or tongues 29 and 30.
  • This arrangement permits dual interengagement, so to say of the sliders 13 and 14, so that these sliders can be securely prevented from any misalignment relative to each other as the pin member 22 is inserted into or removed from their guide channels.
  • FIG. 7 there is illustrated a modification of the preceding embodiment of FIGS. 1 to 6, in which the tongues 29 and 30 protruding from the respective Wings 15 and 16 of the slider 14 are replaced by those which have unvarying thickness and width, that is, are not tapered like the tongues 29 and 30.
  • Only one, 29a, of such modified tongues is illustrated in FIG. 7 for the sake of simplicity, together with a correspondingly modified recess 27a to be formed in the other slider.
  • its leading edges are suitably rounded as indicated at 31 in the drawing. It is, of course, assumed that the other tongue is of identical shape.
  • FIG. 8 illustrates another preferred embodiment of the invention, in which the tongue 29b protruding from each of the wings 15 and 16 of the slider 14 has a notch 32 formed centrally in its leading end.
  • the mating notch 32 and protuberancev 33 are calculated to ensure still more correct alignment of the sliders 13 and 14 which would otherwise be insufficient due to the presence of recesses 27, 28 during insertion or removal of the pin member 22 into or out of their guide channels.
  • the concepts of this invention are applicable to a separable slide fastener of the usual box-andpin-coupling type whereby the fastener can be opened from one end only.
  • Only the box member 34 of the box and pin separable coupling is illustrated in FIG. 9, but it will be apparent that this box member is to be used to render the slider 14 stationary in the first described embodiment of FIGS. 1 to 6.
  • the box member 34 has a pair of tongues 29c and 30c formed integral with its top and bottom plate portions 35 and 36, respectively, at their ends to be disposed opposite to the contracted end of the slider 13.
  • This box member is to be employed in combination with the slider 13 in the well known manner.
  • the tongues 29c and 300 as illustrated in FIG.
  • FIGS. 9 are shaped exactly like the tongues 29 and shown previously in FIGS. 2 and 3 in particular, it will be understood that they can be modified in shape like the examples of FIGS. 7 and 8, with corresponding modifications in the shape of the recesses to be formed in the cooperating slider 13.
  • a separable slide fastener of the class including a pair of stringers having longitudinal rows of interlocking fastener elements on their opposed edges respectively, a pair of sliders arranged reversely with respect to each other on said rows of fastener elements for longitudinal movement therealong to engage and disengage the same, each of said sliders having a body consisting of a pair of spaced-apart and interconnected wings apadted to define a generally Y-shaped guide channel therethrough, a top member arranged on one end of one of said stringers for retaining said sliders on said one stringer when the other stringer is completely separated therefrom, and a pin member arranged on the corresponding end of said other stringer for insertion through the guide channels of both of said sliders, the improvement comprising a pair of recesses formed at that end of one of said sliders disposed opposite to the other slider, said recesses being formed in the respective wings of said one slider so as to be invisible at least through the outside surfaces of said wings, and a pair of tongues formed at the corresponding
  • each of said recesses is of generally trapezoidal shape, as seen in a plan view, tapering inwardly both in width and thickness, and wherein each of said tongues is of corresponding shape.
