Definitions

This invention relates to slide fasteners and, more particularly, to a slide fastener which greatly improves the appearance of the garment to which it is applied.
a hook and eye it is common to attach a hook and eye to the body of the garment above the free ends of the slide fastener for the purpose of eliminating tape separation and gapping.
a hook and eye is not Wholly satisfactory because it is difficult and expensive to properly position and sew the same to the garment; and once sewn to the garment, it does not necessarily assure that the overlap of the garment will lie fiat and effectively conceal the fastener as well as the hook and eye.
hooks and eyes applied in the manner de- 3,605,208 Patented Sept. 20, 1971 scribed above' generally are of a relatively large size that greatly detracts from the desired appearance of the garment.
the present invention relates wherein the general object of this invention is to provide a cooperable hook and eye closure combination located on the opposed marginal edges of the tapes.
Another object of this invention is to provide an improved hook and eye closure attached to the carrying tapes during the construction of the slide fastener.
a further object of this invention is to provide a simple, inexpensive hook and eye closure which permits the overlap of garment to lie flat and which prevents the upper ends of the tapes from separating.
Still another object of this invention is to provide a hook and eye closure for a slide fastener in which the eye member is formed from the edge of one of the tapes.
FIG. 1 is a plan view of a fragment of a length of gapped slide fastener chain
FIG. 2 is a view similar to FIG. 1 showing the top and bottom stops as well as the hook and eye members in place on the stringer tapes;
FIG. 3 is a partial plan view of a finished open end slide fastener of this invention.
FIG. 4 is an enlarged plan view of the finished fastener shown in FIG. 3 with the hook and eye members engaged;
FIG. 5 is a partial sectional view taken along the lines 55 of FIG. 4.
FIGS. 1 to 3 of the drawings there is shown a length of slide fastener chain 10 of the continuous filament type which is generally supplied in rolls to the operator for the finishing operations.
Each length of slide fastener chain '10 comprises a pair of continuous length stringer tapes 12 with each having a continuous length of filament 14 secured to the beaded edge 16 thereof.
Filament 14 is deformed to provide a continuous series of spaced apart interlocking fastener elements 18 attached to the opposed beaded edges 16 of tapes 12.
the filamentary configuration shown in the drawings is of the helical coil type, although the invention is also applicable to a ladder type filamentary configuration such as is shown in US. Reissue Patent No.
gap portion 20 of continuous fastener chain 10 is indexed and positioned within a mold device (not shown), with the beaded edges 16 of gap portion 20 of stringer tapes 12 spread apart substantially in the manner as shown in FIG. 2.
a molten plastic material is injected into the mold, cooled, and the mold separated to leave the mold product 24, as best shown in FIG. 2.
Mold product 24 includes a sprue 26 as well as two elongated runners 28 and 30 of plastic material.
Bottom stop 32 for one slide fastener is located at the extreme end of runner 28.
Runner 30 is bifurcated at its lower end with each arm of the bifurcated portion extending laterally towards opposed beaded edges 16 of stringer tapes 12.
One arm of the bifurcated portion acts as a gate for a hook member 34 having a support portion 36 overlying the margins of tape 12 with hook member 34 located substantially symmetrical of tape 12.
the plastic material is directed along beaded edge 16 to form a plastic runner 38 which surrounds and partially impregnates beaded edge 16.
Runner 38 extends from hook member 34 to a top stop 40 of the fastener with runner 38 providing a pliable but relatively firm section to support beaded edge 16 and the marginal edges of tape 12 located adjacent thereto.
the other arm of the bifurcated portion terminates in an eye member 42 that is of a D shape in plan.
Eye member 42 that is of a D shape in plan.
Substantially a mirror image of eye member 42 is formed on the lower surface of tape 12, whereby in the formation thereof, the injected plastic material impregnates the voids in the tape fabric and becomes substantially a unitary mass of plastic material whose outline on the top and bottom surfaces of the tape has the form of the letter D.
the shank or bridge 44 of eye 42 is plastic which surrounds beaded edge 16 resulting in a tough substantially cylindrical member interconnecting the upper and lower arms of eye member 42.
a laterally disposed support member 46 provides added strength to eye member 42 and prevents the same from being removed from tape 12.
Central portion 48 of eye member 42 is not impregnated with plastic material as it is to be cut out in a subsequent operation.
a plastic runner 50 extends from eye member 42 to a second top stop 52 on stringer tape 12, which runner impregnates its beaded edge 16 to provide a pliable but relatively firm section to support beaded edge 16 and the marginal edges of tape 12 located adjacent thereto, in a manner similar to that previously disclosed with relation to runner 38.
both runner members 38 and 50 maintain their short lengths of beaded edges 16 of stringer tapes 12 in a relatively firm, but pliable condition.
a cutting operation trims mold product 24 from the slide fastener chain while simultaneously severing the chain intermediate hook 34 and eye 42 and bottom stop 32. At the same time central portion 48 of eye member 42 is cut out.
This cutting and severing operation can be performed in a punch press using a die member which positively locates mold product 24 and stringer tapes 12 therein, whereby mold product 24 can be quickly and accurately removed and individual fasteners manufactured.
the finished hook member 34 and eye member 42 can now be operatively engaged to draw stringer tapes 12 together, whereby beaded edges 16 located above hook and eye members 34 and 42, respectively, will be drawn together and maintained in substantially parallel relation to each other.
Runners 38 and 50 while they end to maintain tapes 12 in a given condition, have some flexibility so that each can be bent towards the other when the separated hook and eye members are initially brought together. It will be observed that when slider member 22 is moved to its fully closed position, top stops 40 and 52 will be located within the throat portion of slider member 22, with runners 38 and 50 projecting out of slider member 22 and normally being splayed apart. However, once hook member 34, which has an elongated curved tongue 54, is engaged with bridge 44 of eye member 42, tapes 12 above the hook and eye members are brought together in sub stantially parallel relationship. Runners 38 and 50 tend to maintain tapes 12 in a straight line condition, which condition tends to separate or splay the same apart.
hook 34 and eye 42 acts against the forces tending to splay tapes 12 apart, and these same forces will maintain hook 34 and eye 42 in its engaged condition. Because elongated curved tongue 54 wraps about bridge 44, tapes 12 can only be moved in their common plane towards each other to disengage hook 34 from bridge 44 of eye 42.
an improved hook and eye member, top and bottom stops and method of making the same which can be inexpensively and easily fabricated without the necessity of expensive tools or other equipment.
the improved hook and eye, top stops and bottom stops are formed of a material which can easily be added to a fastener.
a hook and eye and end stops for an open end type of slide fastener which is constructed and arranged so as to provide a maximum closing movement of the slider.
an open end slide fastener which includes:
stop means carried on each tape edge above the uppermost fastener element defining an open end of said slide fastener opposite said one end for preventing said slider member from being removed therefrom, with those portions of each tape in and immediately above said throat portion of said slider member splayed apart when said slider member is in the fully closed position;
said eye means including a bridge superimposed on an adjacent part of the edge of said other tape with said hook member entering said eye means and engaging said bridge to bring said tape edges into substantially parallel relation;
(h) means extending along each tape edge above said stop means thereon exerting forces tending to maintain the said portions of each tape splayed apart whereby the same forces act to retain said hook member in an engaged condition with said bridge.
a slide fastener according to claim 4 wherein said curved tongue member can be disengaged from said center portion of said eye means by movement in only one direction relative to said eye member.
