The invention relates to a bite seal slider, in particular such a slide, which acts on an unfinished hot seal chain is applied after this or the like on a garment. has been attached.

It is a common practice among manufacturers of confection or the like., Long hot lock chains instead of finished To buy cut zipper lengths, these hot lock chains cut into individual lengths that correspond to the shape and size of the objects in question, and the so required To sew lengths of the hot-fastener chain to the objects or on other way of fastening. Other parts of the hot seal, such as top and bottom end stops and slides, will be in progress attached to the sewing process. It was found that by This practice increases the cost of manufacturing these items considerably / can be reduced.

However, this precision has disadvantages with regard to that Passing the separated at the edges of an opening in a certain object, as mentioned above, fastened straps of the lleißver close it through the guide grooves in the slider, so that the rows of zipper elements adhere to each other opposite edges can interlock in the correct position with respect to one another. It's a high grade of Skill and mental concentration on the part of the operator are required to operate the two fastener tapes at the same time thread into the slider by hand without misalignment or mismatch between the interlocking ' To cause locking elements.

Lend to the now interlocking, however in the wrong position in relation to each other locking elements are then separated from each other, see above that the closure elements only within dos slide still with each other remain engaged, which is now at one end of the straps. Thereupon the correct iaisricht de in incorrect engagement with one another locking elements one of the fastener tapes pulled forcefully through the slide, wherein the elastic deformation of the closure elements is used (which is made from a continuous plastic wire in screw-helical or meander shape), so that the two carrying straps are aligned with their ends in relation to one another. To During this process it is necessary to return the two fastener tapes

to pull the output end of the slide so that it is is at or near the point on the tapes where a j lower end stop is to be attached. This lower end stop is attached to the fastener after the fastener straps it has been pulled back through the slider in the closing direction of the zipper.

Assembly of zippers as described by Dalben However, it has the disadvantage that the closure elements often get caught in the guide groove in the slide when the fastener tapes after aligning or correcting the position of the incorrectly aligned Yer closure elements in relation to one another in the opening direction of the zipper can be pulled through the slider. The reason for this is the additional weight of the den Zippered object through which the straps caused to hang vertically downwards with the result, that the coupling heads of the closure elements tend to be raised near the exit end of the slide or after to be moved up. The vigorous pulling of the fastener tapes in such a condition through the limited space in the slider often results in permanent deformation or other damage to the closure elements.

In view of the above difficulties in conventional assembly of zippers is to create a novel slider for zippers by the invention v / ground, which has design features that allow the straps, in particular beforehand to a piece of clothing or the like. fastened straps allow extremely easy and without the closure elements in the Fülirungsrinne in the slide can get caught in the slider.

According to the invention is a zipper slider with an input and an output end is provided which has an upper and a lower wing which at one end by means of a web are connected to each other and of which the upper wing with an upwardly protruding and with a pull tab pivotally connected bracket is provided and spaced apart, integrally formed with it side flange has, which between .sich a substantially Y-shaped Limit the guide trough for the closure elements. This slide ! ber is characterized by the fact that the distance between the flanj see larger, measured from their outer circumference aiu exit end j is as the corresponding distance atn input end and that the Flanges are provided with tape guide surfaces, the width of which ! is largest at the exit end, making the valve body a!

Fig. 1 shows a slide constructed according to the invention 10. The slide 10 has an upper wing 11 and a lower one Wing 12, which at one end by a web 13 with each other are connected. A bracket 14 protrudes from the upper wing 11 upwards and a pull tab 13 can be pivoted with the bracket 14 tied together. Side flanges 16, 16 ', which are spaced apart from one another, are formed in one piece with the upper wing 11 and delimit a substantially Y-shaped guide channel 17 between them, through which the ends of the locking devices E run (Fig. 2).

According to an important feature of the invention, the slide 10 is essentially triangular in its horizontal extension, the outlet end 18 forming the base, as illustrated in FIG expanded to the outside, where they reach their maximum width B, B ¹ , whereby they form widened or enlarged guide surfaces 19, 19 ', which serve to support the opposing fastener straps T, T ^{1 of} the slide fastener chain F (Fig. 3) during installation of the slider 10 horizontally flat, as described later. Opposite the output end 18 of the slide 10 is an input end 20 through which the carrier tapes T, T ¹ enter the guide channel 1? ' to be introduced.

The distance V / between the side flanges 16, 16 'is measured of its outer circumference, in contrast to conventional slides, is larger at the output end 18 than the corresponding one Distance W * at the entrance end 20.

As shown in Fig. 3, the slider 10 is that described above Construction upside down, i.e. with

his! upper wing 11 turned downwards, arranged on a slide holder 21 and is in a position in which it can accommodate the two fastener straps T, T ^{1 of} the slide fastener chain F attached to an item of clothing G. The two fastener tapes T, T 'are inserted one after the other through the input end 20 into the guide channel 17 of the slide 10 and the position of the strings of the closure elements E in relation to one another is corrected as described above, whereupon the fastener tapes T, T' back again be pulled through the slide 10 in the opening direction of the tie. Here, if the design features of the invention were not present, the closure elements E on both or on one of the fastener tapes T or T 'with their coupling head portions Ea above the normal horizontal of engagement with those of the corresponding fastener tape T' and would be under the Influence of the additional weight of the garment G- caught at the exit end 16, as shown in FIG.

This problem is addressed in accordance with the invention by providing the widened guide surfaces 19, 19 'of the side flanges 16 'released, which is laterally over the inner edges of the fastener tapes T, T ', on which the rows of locking elements E are attached, and extend beyond the tape areas Ta, Ta 'to the support tapes flat against the guide surfaces 19, 19 'to keep and prevent them from being under the influence the weight of the garment G bend down where ·? aligned horizontally by the rows of the closure elements E. held and pulled through the exit end 18 into the Fülirungsrinne 17 of the slide 10 v / ground.

Slide holder 21 is also used to hold the slide 10 to hold holder 21 firmly in place on the slide during assembly.

At this point it should be mentioned that the FIG. to 3, in particular FIG. 2, apparent dimensional ratios have proven to be particularly useful.
