Zipper with a bridge-like upper end stop

The innovation concerns a friction lock with a bridge-like one upper end stop,

Bridge-like upper end stops are usually used as a connecting link for connecting the upper ends of the zipper straps and zippers provided with such bridge-like end stops are largely used in garment pockets or slots and other openings provided with zippers, e.g. in handbags, suitcases etc. used. There have already been proposed numerous bridge-like upper end stops, mostly in terms of their mechanical strength and
their storage stability are not completely satisfactory. These
However, properties are necessary so that these end stops can withstand high stresses during the opening and closing of the zipper by the slide, as well as stresses through which the carrier tapes are pulled apart sideways. One of the numerous facts that are unfavorable

on the durability of the known brüoken-like upper end stops affect is, in particular, that the connection with both the coupling elements and the straps to is weak.

In view of these disadvantages of the conventional bridge-like upper end stops, the object of the innovation is to a zipper with a novel improved bridge-like to create an upper limit stop which is stable for a long time in terms of its position and in terms of its mechanical properties Properties.

The bridge-like upper end stop according to the innovation is arranged such that it attaches a group of coupling elements. surrounds an upper end section of the zipper and on: this rests, as well as another group in front of coupling elements that join the first group, but not in coupling I engage with each other, whereby the upper end stop together: jait tightly fastened these coupling element groups with the supporting straps melted. j

The tasks i on which the present innovation is based are, according to the innovation, in the case of a zipper with two one-on-one ί of the associated fastener tapes, on one longitudinal edge of which a row of coupling elements is attached, along which a slide i for coupling and uncoupling of the coupling elements is reciprocable, as well as with a bridge-like upper end stop which is attached to the j Oberend3 öss zip closure to limit the slide movement: is provided, in particular achieved in that the bridge-like upper end stop on a first group of coupling elements this upper end surrounds, which remain in the coupled state, and a second group of coupling elements which are attached to the first group connect and remain in the unsupplied state, and that the end stop, together with the first and second coupling element groups, is firmly connected to the straps.

Further advantages, details and features of the innovation emerge from the following description. On the drawing is the innovation shown for example, namely show

Fig. 1 is a plan view of the upper end of a zipper, on which according to the innovation bridge-like upper end stop is applied,

FIG. 2 shows a cross section in a plane II-II of FIG Fig. 1,

3 shows a plan view according to FIG. 1, using another bridge-like upper end Anscblages according to the innovation, j

4 shows a cross section in a plane IV-IV of FIG. 3, and

Fig. 5 is a top plan view of Fig. 3, using another bridge-like upper end stop according to the innovation.

1 and 2 show the upper end of a _{zip fastener F 1} which generally has two fastener tapes T ^, T2, on one longitudinal edge of which a row of coupling elements E of conventional design are fastened by means of sewing threads S; the two rows of coupling elements E can be coupled and uncoupled in a known manner by means of a slide (not shown). ^l -

A bridge-like upper end stop 10 connects the upper ends of the two carrier tapes Tj, T2 ^and prevents the slide from being pulled out over the end of the zipper on which it is attached. The bridge-like upper end stop 10 according to the innovation has a body 11 which is fork-shaped at one end, so that claw-like sections 12, 13 protrude downwards. The body 11 surrounds or

covers a first length or group of interengaging coupling elements Ea, while the crotches or the claw-like ones Section 12, 13 has a second length or group of raut, interengaging dome brackets Sb of the respective Support straps T-), T2 surround or cover.

The forks or claw-like sections 12, 13 delimit a bulge or slot 14 between them for receiving the neck or the wedge-shaped section of the slide and their circumference 12a or 13a each has an outline that has practically the same shape as the inner circumferential walls of the Slide flanges, so that the slide can be picked up unhindered and locked in close contact with the upper end stop 10. The upper end stop 10 also has outwardly directed lateral lugs or flanges 15, 16 which adhere firmly _{to the corresponding support straps Tj, T 2.}

The material from which the bridge-like upper end stop 10 according to the present embodiment is made corresponds preferably the material of the coupling elements E, so that these zipper components form an intimate bond with one another can enter. As part of the present innovation, there are both the coupling elements and the bridge-like upper end stop for example from thermoplastics. This makes it possible to move the bridge-like upper end stop 10 under the action of heat and pressure, for example through high-frequency or ultrasound treatment, or by means of an injection molding process with the zipper F to create an adhesive bond or to create an ' of merging. When using metallic coupling elements j one preferably uses an injection-molded bridge; like upper end stop 10. The type of attachment of the bridge-like upper end stop 10 on the zipper F is not essential to the innovation; he can, as shown in Fig. 1 and 2, ur-, initially preformed and fixed by heat and pressure

i -5-;

or punched onto the bite cover after it has been applied will,,

The essential features of the innovation consist rather in the arrangement of the bridge-like upper Snuanachlagö 10, which overlaps a group of coupling elements Ea at the upper end of the fastener F, which remain in the coupled state, and another group of coupling elements Eb, which adjoins the first coupling element group are uncoupled. The upper end stop 10 is firmly connected together with these coupling element groups with the support straps T-], T _2.

A modified embodiment of the bridge-like upper End stop 10 is shown in FIGS. The end stop 10 lies in a similar manner on both a first group of coupled coupling elements Ea as well as on a second group of uncoupled coupling elements Eb on * The bridge-like upper end stop ΙΟ according to this embodiment is characterized from the fact that it is attached to the keiss lock F by injection molding, as FIG. 4 shows. :

Fig. 5 shows another embodiment, the bridge! like upper end stop 10 according to FIGS. 3 and 4 is essentially the same, but in which a strip uiermopla- | Stischen material 17 is fastened together with the body of the bridge-like < upper end stop 10 at the upper end of each support tape Tj, T ₂ , so that the support tape end is reinforced. The stripper 17 can together with the bridge-like upper end stop 10 through; Be applied injection molding. i
