Slide fastener and method of making the same

The invention relates to slide fasteners, and more particularly a zipper which greatly improves the appearance of the garment to which it is attached.

It is common on garments and in particular Garments for women to gather the edges a zipper to an opening of the garment use. In general, the extreme end portions of the slide fastener tapes that do not interlock gripping closing elements are located when fully closed Position of the sliding element not in the desired juxtaposition brought. The ligaments are more likely to separate or gape apart and attached to theirs outermost end areas to form an opening that is unsightly and from the smooth and neat contour of the garment distracts greatly. Where the type of attachment so

0098 3 8/0125 " ² "

If there is a portion of the garment overlying the zipper, a large gap between the tapes cannot easily covered by the normal overlapping.

In general, it is common to be above the free ends of the zipper to attach a hook and an eye to the garment itself to prevent tearing and gape to eliminate the ligaments. In practice, however, a hook and eye is not entirely satisfactory as it is difficult and expensive to apply and sew in place on the garment, and when Once they are sewn to the garment, this does not necessarily ensure that the overarching Piece of the garment lies flat and completely and effectively covers the zipper and hook and eye.

In the prior art, as shown in U.S. Patents 2,181 and 3,287,779, hooks are made of metal and eyelets attached to the slide fastener, the carrier elements of which are riveted to the beaded edges of the slide fastener tapes are. Since both the hook and the eye of the opposite Edges of the bands stick out, the dimensions of the resulting shape often prevent the beaded edges of the bands from doing so can be contracted so that they are substantially parallel to each other. Even if, as shown in U.S. Patent 2,962,725 is, hooks and eyes are sewn to the ties therefore do not lay the overlapping piece of clothing smoothly over the zipper, and zipper and hooks and eyes remain unhidden.

Furthermore, the hooks and eyes used in the above manner are usually of relatively large dimensions, whereby the desired appearance of the garment suffers greatly.

The improvement according to the invention is achieved by a zipper with one open end, with a sliding element with mouth and neck area, and with a pair of zipper strips connected to one another at one of their ends and carrying a large number of interlocking closing elements, each of which is closed when the sliding element is moved in the direction of a 'closed' Position connected to one another and to be able to be released from one another in the direction of an open position, and with a lower stop connecting the straps at one of their ends, characterized by interconnectable elements that are attached to the edges of the straps above the uppermost closing element at said one end opposite open end of the zipper are attached and both prevent the sliding element from moving away from there , _ the areas of both straps within the neck area of the sliding element and immediately above it in the fully closed position of Eq The elements are spread apart and also serve to draw together the areas of the ligaments located above the sliding element against the force which spreads them apart, essentially parallel to one another.

The present invention also provides a method to make the above open ended Zipper in front of the interacting hook 'and öeenelemente on a zipper length with a couple of zips * - fastener tapes are formed, both of which interlock with rows ender locking elements are provided which are attached to the opposite edges thereof j, wherein . There is a short piece on both bands without these fasteners. The procedure is characterized by inserting the. named Tleißverschlußbandpaares in a form, where the Piece without elements to lie in the middle, injection of plastic material into sprues and channels of the mold,

to at the same time make a lower stop close to each other connected elements at one end of the element-free piece, a pair of upper stops at the other end of the element-free piece Piece, and a hook and eye element between the to shape upper stops and the lower stop, cutting off said sprue areas from plastic material, which connect the lower stop, the upper stops and the hook and eye, with an area from which the eye element carries The tape is cut out and one zipper is cut transversely from the next zipper close to the ends of the tape .

In the following the invention is attached with reference to the Drawings described in more detail:

The other arm of the forked area terminates in an eyelet element 42 which, in plan view, has the shape of a "D". A mirror image of the eyelet area 42 vd.rd is formed on the lower surface of the band 12 . During the formation of the same, the injected plastic material impregnates the gaps in the belt fabric and a substantially uniform mass of plastic material is created, the shape of which on the upper and lower surfaces of the belt has the shape of the letter "D °. The shaft or bridge 44 of the eyelet 42 made of plastic, softer the bead edge Ib surrounds and a solid, thus forming substantially cylindrical, the upper and lower arms dee eye member 42 connecting each element. a affixed to the side holding member 46 contributes to the attachment of the eye member 42 and prevents that the same can be removed from the belt 12. The middle area 48 of the eyelet element 42 is not impregnated with plastic material, since it is to be reconciled in a subsequent operation , where the

Running element impregnated the bead edge 16 and a bendable, but a relatively fine section which forms the bead edge 16 and holds the side areas of the belt 12 which are adjacent in a similar manner as already described in connection with the running element 38 is disclosed. Be that way through the running elements 38 and 50 the short lengths of Bead edges 16 of the bands 12 are designed to be relatively firm but flexible.

As best shown in Fig. 3 too. Is seen., The casting 24 is cut out of the zipper by a cutting process, the length between the hook 34 and eye 42 and the lower stop 32 is severed at the same time. At the same time, the middle area 48 of the eyelet element 42 is cut out. These tendon cutting and severing operations can be performed in a punch press using a molding element which constrains the casting 24 and tapes 12 in place, allowing the casting 24 to be quickly and accurately removed and fabricated into custom zippers.

To use the zip fastener, as shown in FIGS. 4 and 5, the finished hook element 34 can now be hooked into the eyelet element 42 in order to draw the straps 12 together, whereby the bead edges 16 lying above the hook and eyelet elements 34 and 42 are drawn together and are held substantially parallel to one another. While the running elements 38 and 50 hold the straps 12 in a given condition, they have some flexibility so that they can be bent towards one another when the hook is initially hooked into the eyelet. It will be noted that when the sliding element 22 is in the fully closed position, the upper ends 40 and 5 ² lie in the neck region of the sliding element 22, with the running elements 38 and 50 protruding from the sliding element 22 and normal.

are usually spread apart. However, if that is with a elongated curved tongue 54 provided hook element 34 in When the bridge 44 engages the eyelet 42, the straps 12 over the hook and eyelet become substantially parallel to one another brought together. The running elements 38 and 50 hold the bands 12 in a straight line, which is why they spread apart. This is how the joining works of hook? 4 and eyelet 42 against the forces that the Spread the straps 12 apart, and these equal forces hold the hook 34 and eyelet 42 hooked. There the elongated curved tongue 54 wraps around the bridge 44, the straps 12 can only be moved against one another in their common plane, in order to remove the hook 34 from the bridge 44 or the eyelet 42 to solve.

The result of the present invention is to provide an improved loop, top and bottom hook Stops and a method of making the same which is inexpensive and easy to manufacture without expensive tools or other facilities would be required. Furthermore, the improved parts, namely hook and eye and upper and lower stops formed from a material that can be easily attached to a zipper. There are Also hooks and eyes and end stops for open ended zippers are provided that are so constructed and arranged that a maximum closing movement of the sliding element is ensured.
