Definitions

• the invention relates to a surface zipper for connecting tensile objects, in particular for releasably connecting tensile clothing parts such as belts, jackets, vests, trousers and skirt waistbands as well as for bandages and the like, each with two ⁇ because with hook elements and 'loop elements occupied friction surfaces.
• a .Manufacturing process for such band-like surface zippers is described in DE-OS 33 06 "757.
• the previously known surface zippers each have a friction surface on the objects to be connected, so that each friction surface forms a closure part and the tensile load acting on the friction surfaces is directed in the opposite direction, as is shown, for example, by DE-OS 32 05 522 for a waist belt fastener.
• the friction surface arranged on one belt end faces outwards and the friction surface arranged on the other belt end points inwards.
• the outward-facing friction surface is only completely covered and invisible if it is completely covered by the inward-facing friction surface.
• the invention has for its object to develop a surface * zipper of the known type in such a way that, despite the infinitely variable adjustability, no friction surface can be seen regardless of the adjustment range.
• the solution to this problem consists, according to the invention, in that both of the friction surfaces forming a closure part are of equal length and are connected to one another on their opposite sides in a non-displaceable manner, and that the other closure part consists of a flat bolt which can be inserted between the friction surfaces which can be detached from one another with a profile, which has at least one web which extends essentially transversely to the direction of pull, the web being so thin that the hook and loop elements of the friction surfaces outside the area covered by the bolt come into contact with the surface by external pressure .
• the surface zipper according to the invention no longer develops its closing effect by frictional engagement - as before • against a parallel displacement of the two friction surfaces to one another, since these are non-displaceably assigned to one another, rather by virtue of the fact that the partial areas of the friction surfaces hooked into one another in the pulling direction of the bolt or the webs of the bolt of a displacement of the one or more webs and thus of the bolt counteract.
• the immovable connection of the two friction surfaces means that none of the friction surfaces is ever visible.
• the bolt itself is visible, but it can be designed freely and in terms of color. But the bolt could also be made invisible by a hose-like sheathing which is fixed at the fastening end * of the bolt and can be pushed together in a "cuff" manner.
• the two friction surfaces or their carrier tape are connected to one another.
• For a longitudinal seam to replace the conventional, well-known link zipper it is necessary to connect the two friction surfaces on one long side.
• Both friction surfaces can also be attached to the ends of a common support band, since they are folded in the middle and fixed in the folded position, which forms a closure part.
• the bartack can consist of a solid woven band.
• plastic and bare steel strips are equally suitable, especially for closures on sporty clothing.
• the two friction surfaces are connected on one side and must be torn open in order to insert a band-like bolt, after which the upper friction surface is folded in and the frictional connection is brought about by hand pressure.
• a not inconsiderable simplification in the handling of a surface zip according to the invention is achieved in that the two friction surfaces are connected to one another in a tube-like manner along two parallel edges, and in that the latch is made of kink-resistant material.
• the interaction of these two features of the invention results in a simple plug-in closure, because the bolt only needs to be pushed between the two friction surfaces, for which purpose it is expediently sharpened like a blade at its free end. For the same reason, the free end can also be arrow-shaped.
• the tensile load is obtained with a maximum of transverse webs, since each partial frictional engagement on the sub-areas of the friction surfaces arranged upstream of the webs opposes the tearing resistance and thus absorbs tensile load. Since the dimensions of the partial areas in the direction of pull become smaller the more webs are provided on the length unit, with a maximum of webs there is the least reserve of frictional engagement in the event that the bolt temporarily slips under high tensile load, because the bars quickly tore open the short sections. The situation is reversed if, for example, only one web is provided on the bolt, the bolt is thus profiled like a hammer head. There is then only one area of frictional engagement in the direction of pull in front of the single web, so that even a slight exceeding of the limit tensile load leads to the bolt slipping, but over a maximum long way. , - - -.
• a buckle-like appearance can be obtained in that the outer friction surface is provided on its outer surface with a metallic cover which, by means of two beveled edge strips, encompasses the inner friction surface on two parallel longitudinal edges, The two friction surfaces are virtually clamped in via the folded edge strips and are therefore connected to one another so that they cannot move.

• Both friction surfaces 1, 2 are of equal length and are connected to one another on one narrow side by means of a plurality of transverse seams 3.
• the hook elements 2a of the friction surface 2 are, as usual, incorporated on a carrier tape 4 which ends in a bolt 5 according to FIG. 2 when the closure part consisting of the two friction surfaces 1, 2 and the closure part consisting of the bolt 5 form a bandage should belong.

• the latch In the embodiment according to FIGS. 4 and 5, the latch must therefore be pushed between the friction surfaces 1 and 2.
