Abstract

Surface zipper with two closure parts (1, 5), called fastener of the adherence type for connecting traction load objects, particularly parts of garments, wherein both friction surfaces (1, 2) provided with hook elements (2a), respectively loop elements (1) are undisplaceably connected to at least one edge (3) and form a part of the closure. Between the friction surfaces (1, 2) there may be inserted a flat crosspiece (8) forming the other part of the closure. Through the profile of the crosspiece (8) at least one transverse bridge (7) is formed. The area which is before the transverse bridge in the pull direction of the friction surfaces which form an adherence-type closure by means of an outer pressure is responsive to a release displacement of the crosspiece by a resistance producing a connection depending on the traction force for both parts of the closure. The more transverse bridges (7) are provided in the crosspiece (5), the higher is the resistance to the closure release upon a high traction load.

Area zipper for connecting tensile objects

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. Here, the friction surface arranged on one belt end faces outwards and the friction surface arranged on the other belt end points inwards. As a result, the outward-facing friction surface is only completely covered and invisible if it is completely covered by the inward-facing friction surface. However, since statements a length adjustability of the method is desirable for a covering position of the two friction surfaces is not guaranteed, but di _e outwardly facing friction surface is usually visible, which is unsightly, and the inwardly facing friction ^' Partially there is no frictional engagement with the other friction surface and could curl up, which is also undesirable. Therefore, the solution according to DE-OS 32 05 522 provides an umbilical panel on a belt end, which covers the fastener parts of the waist belt at every length setting. Another and more significant disadvantage of the known surface zippers can be seen in the fact that in order to adjust a large Verulullberulchu dlu outward-facing Uelbunqsi.läσhe must be made longer than the inward-facing friction surface, if one considers the the narrowest setting. eg: does not want to oversize the necessary adhesive length of a belt, ie it unnecessarily makes both friction surfaces of the same length. Especially if but the outwardly facing friction surface is made longer than the inwardly facing friction surface ^', the possibility of visibility of a Reibungs¬ enlarged 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. Depending on the setting position that the bolt occupies in relation to the closure part consisting of the friction surfaces, 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.

Depending on the intended use of the surface zip according to the invention, one has to choose the way in which the two friction surfaces or their carrier tape are connected to one another. For a simple bandage, it is recommended to connect the two friction surfaces on one narrow side, e.g. B. to sew so that the upper friction surface can be torn along its entire length to insert the bolt in the closed position. 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. In the case of a simple bandage, the bartack can consist of a solid woven band. For the rest, there are no limits to the choice of materials; Plastic and bare steel strips are equally suitable, especially for closures on sporty clothing. - *. -

As far as described so far, 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.

There are several ways to profile ^' the bar on its effective length' in the sense of the invention. The highest strength of the closure against loosening

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. , - - -.

So you have it by choosing the number of crossbars over the unit of length or their density in your hand, the surface zipper in the direction of maximum possible tensile load or maximum flexibility or maximum sliding distance until the closure is completely separated to interpret.

D, a or the bars of the bar extending transversely to the direction of tension try to tear open the frictional engagement of the hook and loop elements under tensile load, it is appropriate to make the edge of each bar of the bar pointing in the direction of tension sharp and / or thicker than the rest but that the hook and loop elements "web width not so thick because of their marginalized loading height 'on the part of areas no longer in Rei ^* * - can get exercise circuit.

If several crossbars are to be provided on the transom,. A profile similar to a ladder with a central longitudinal spar is recommended in particular for the pushing-in, kink-rigid bolt, in contrast to the ladder with two lateral longitudinal spars, since longitudinal spars belong to the area of the friction surfaces covered by the bolt and therefore ineffective. ^' .

For use of the surface zipper according to the invention with friction surfaces connected in a hose-like manner, 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. ^'In the drawing, three embodiments are shown of a Flä¬ chen-zipper according to the invention, and show indeed

1 a closure part consisting of two friction surfaces in a diagrammatic representation,

F_ig. 2 a band-like bolt for insertion into the closure part according to FIG. 1,

3 shows a plan view of the interlocking closure parts according to FIGS. 1 and 2,

4 ^"is a plan view of a closure with an insertable latch,

5 shows a cross section along the line V-V in Fig. 4,

6 shows a further embodiment with an insertable latch,

Fig. 7 shows a cross section along the line VII-VII _^ in Fig. 6, and Fig. 8 shows a bolt with ^" hammer head-like profile in a graphical representation.

1 shows a friction surface 1 with loop elements 1a on the underside and a further friction surface 2 with hook elements 2a on the top. 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 bolt 5 is provided with rectangular openings 6, which results in webs 7 extending transversely to the tensile load on the closure. If the bolt 5 in the direction of the arrow between the friction

5 surfaces 1 and 2 are inserted and the friction surfaces are pressed against each other, the locking position according to FIG. 3 results when the bolt has been inserted as far as possible between the friction surfaces 1, 2. In Fig. 3 the openings 6 are dotted to show that in 0 these areas the loop elements 1a with the hook elements 2a come into frictional engagement by pressure and oppose the webs 7 in the pulling direction Z resistance. The bar 5 consists in the embodiment of FIGS. 1-3 from a fixed woven band or - as already mentioned - 5 from the support band 4 of the lower or inner friction surface 2, if it is a bandage closure.

The exemplary embodiment according to FIGS. 4 and 5 differs from that according to FIGS. 1-3 initially in that both friction surfaces are connected to one another in a hose-like manner at two parallel longitudinal edges by longitudinal seams 10. This can be seen best from the cross section according to Fig. 5, ^• as in Aμsführungsbeispiel the friction lächen 1 and 2 on the bottom side of a fragmentary portion shown a 5 jacket 11 are mounted. In addition to the longitudinal seams 10, the friction surfaces 1, 2 are also connected to one another on the left narrow side via transverse seams 3. However, on the opposite narrow side, which ends with the edge 11a of the folded-over jacket part 11, the friction surfaces 1, 2 are open.

In the embodiment according to FIGS. 4 and 5, the latch must therefore be pushed between the friction surfaces 1 and 2. The bar 12 pushed in over part of its length has the profile of a ladder with a central cross bar 12a and a number of rungs or cross bars 13, The crosspiece 13a at the free end of the bolt 12 ^• is arrow-shaped and provided with a sharpened cutting edge 13b in order to facilitate the insertion of the bolt 12 between the friction surfaces 1 and 2 which are on top of one another and which may be in frictional engagement. 4, the partial areas of the frictional engagement 14 between the webs 13 are dotted.

The latch 13 is made of rigid material, for. B. bright polished "steel, so that the plug-in closure shown in FIGS. 4 and 5 is primarily suitable for athletic clothing. The latch 12 is provided with an eyelet 14, via which it is attached by means of a loop 15 and transverse seams 16 the folded under portion of the jacket 11 can be attached. ^•

In the exemplary embodiment according to FIGS. 6 and 7, the two fabric edges 20 which are spaced apart from one another are assigned to a bolero-like vest. The outer friction surface 1 (Fig. 7) is on its outer surface in the manner of a buckle. provided with a metallic cover 21 which, by means of two beveled edge strips 21a, surrounds and clamps the inner friction surface 2 at two parallel longitudinal edges. The • two friction surfaces 1 and 2 are also tubular in their length. Both friction surfaces are also attached to the ends of a common carrier tape 4 which is pulled through an eyelet 22 and fixed by a transverse seam 23. A further loop 24 serves ^" for fastening the entire closure part to the fabric part 20.

In the exemplary embodiment according to FIG. 6, the push bar 25 is designed with a profile approximately corresponding to FIG. 2, that is to say it has openings 6 and transverse webs 7. At the front end, the bar 25, which is made of bare steel band, is provided with a sharpened arrowhead 25a. It is connected to the fabric part 20 in the same way as the bar 12 according to FIG. 4 via an eyelet and a loop. The hammer head-like bolt 27 according to FIG. 8 consists of a sufficiently rigid bar 28 and a single transverse web 28a, the edge 28b of which in the direction of tension is formed with sharp edges. Incidentally, the thickness increases of the web 27a in Einstoßrich ^'tung from up to a cutting edge 28c.
