Me present control- looks at a zipper and especially on-end soles for such zippers

Zip fasteners are made up of rigid flexible coupling strips and a slider - which is designed and arranged in such a way that when it is moved in one direction the zip fastener is opened and closed in the other direction
a Ansahl of coupling members is attached _Ä the such

are designed that they with appropriate coupling members ». Rows of the adjoining carrier tape 'domes *' These "coupling elements" can be attached individually to the carrier tape, or they can be formed by bending a continuous thread or wire in order to form a series of loops or U-shaped bends * which act as coupling elements "The invention looks now" in particular. on such zippers "closures * - in which the liuppluhgsglieäer order from such a continuous single thread or wire. Such tear-off fasteners are generally produced in two types. UeT is a type. The single thread is bent into a helical turn, which as such is sewn to an edge of a fastener tape, so that it is opposite to Hegenden turns. the Kupplungsgliederreihe'bilden _β in the other ^ generally referred to as a meander Ausführungsforis wt & d ά, & τ monofilament sunäohst in a plane zig-zacte * fÖmiig and AAnn further up its LSngsaciise U-f5rmig bent * wabeifdie free legs of the shapeless Äbbiegungen comprise the support band edge and sewn onto it »It is also known _{9 to} incorporate both the helical and meandering coupling links into the 'tape' during this', ... being woven Single threads are worked into the carrier tape as warp threads or using 'non-deformed' single threads as chain threads en., whereupon the © coupling links are continuously formed during the weaving of the question tape "

An end stop is provided at each end of the rows of coupling links. which prevents the slide? while his Actuation of the closure is sucked off «The end of the Zipper against the see the slider during the Closing movement defeated * "was considered the upper end stop and the End stop at the other end than the lower end stop. draws *

There are different types of top and bottom end stops known. A top end stop usually consists of a metal clip * which is wrapped around the tape immediately after the steer coupling link of the ropes or over the last coupling « link and the lanyard is clamped »A bottom end stop usually consists of a metal bracket or a Bracket, which around * both 'straps directly below the last, th coupling links the bump © is clamped. Possibly are these brackets around the last I coupling links and porters clamped around to hold them together at this point.

In the case of zip fasteners where the coupling links are made from a continuous single thread, it is rare that the coupling links between the slide and the lower end stop come out of contact with one another under a strong force be coupled when a strong pull is on

the slide is exercised against the lower stop *. Immediately above the lower end stop, however, there are no or three pairs of coupling elements out of engagement. They cannot be coupled with one another again because the coupling elements or coupling loops that are not in engagement are so large that they can enter the SeMeber body and thus not get into the coupling zone within the slider body. Once this deficiency has occurred, the coupling links directly adjoining the lower end stop remain constantly out of engagement with one another and the remaining links can easily open under an occurring stay.

According to the present hiring, a zipper is now proposed * * in which the coupling links are formed from a continuous thread and the end stops consist of a pin which is inserted into the arch of the linging canal, which through the coupling parts of some coupling links on one side end are formed by one or both Kupplungsgliederrelhen "the strength of the pin is in this case _a so that it tsird held by friction between the pin and ueen Kuppluhgsgliedern in its place. The pin can be made of metal or a firm, resilient plastic material

Such an end stop consisting of a pin can be used as a

upper or lower limit stop used; will. If it is used as an upper end stop, it is inserted into the longitudinal channel, which is formed by some coupling members in a row and the edge of the fastener tape on which the coupling members are attached. With a lower end stop, the pin is inserted into the common longitudinal channel introduced, which is formed between the coupling parts by different coupling links of both rows, so that this prevents the. ICupplungsglieder into which the pin is inserted and the sindi coupled together can uncoupled ?? ground when the slider reaches the affected area "

Preferably, the outer surface of the pin is roughened, thereby keeping example 'by quarrels or Sewinde- the friction between the pin and the Kupplungsglieöern to vergrössem "For the pen more secure in its position, it may be expedient may be ₅ something to apply liquid glue between the pen and the sides of the longitudinal channel into which the pen is inserted «.

The hiring is on the attached drawing in one embodiment shown and that shows ~ \ __

Figo 1 is a front view of a zipper according to the innovation and

Fig. 2 shows a section on the line HIJ de * »Fig. 1 ..

As can be seen from Fig. 1 * the zipper consists of "two rows of coupling links * polygons are formed from a continuous thread made of plastic memory material, namely this ¹ single thread is initially bent gick-saek-shaped in one plane. ,, being flattened along the center line Coupling part © 2 «2 ^ΰ - are formed and then this zig ^ zag-shaped pattern is bent in the center line in a U-shape and the legs are then attached to a strap 3, for example by sewing or * Schwelssen,?

The outer surface of the pin 5 is roughened by hand or a thread
