Fastening device comprising a net and a touch fastener

The invention relates to a fastening device having the features of The preamble of claim 1.

It is known, adhesive parts textile surface fasteners for fixing to use mosquito nets. It is woven and / or knitted adhesive tapes whose interlocking mushroom-usually are formed. The attachment of the fly screen is done in the way, that self-adhesive pressure sensitive adhesive tapes rush of around the window frame glued and then trimmed to size with flyscreen their edges are pressed onto the adhesive tapes. The interlocking elements penetrate the mesh formed by the lattice-shaped structure Fly screen and hold it so tightly.

A disadvantage of this type of pressure-sensitive tapes, that for a good Verhakungswahrscheinlichkeit provide a number of interlocking elements must that is significantly greater than the number of stitches. Here one is with regard the number of interlocking elements of machine gauges and / or pitches due to the manufacturing process of weaving textile or knitting bound.

In contrast, reveals the US - A - 4,001,366 already a method to non-textile base produce adhesive fastener material having engaging elements, by the longitudinal ribs of a planar extruded material in a direction transverse to the longitudinal ribs extending direction very finely sawed or are cut and the remaining between the incisions Supernatants by subsequent stretching of the sheet material in Direction of the longitudinal ribs are away from each other, so that a geometrically regular arrangement of these supernatants in longitudinal and transverse rows arises representing the interlocking elements of the touch fastener material. the compound is As with any type of application fibrillar Material called. The idea of ​​the distance of hooking on the Fibrillenabstand a regularly structured material, in this So the sense coordinated with the mesh width of a regular mesh material, is not disclosed.

The US-A-4993471 is concerned with an application, a flexible mesh material fix reversible means of a fastener tape, especially of vehicle openings, such as the window or the sliding roof. In the given there is the solution provided with interlocking elements Touch fastener material first by example, gluing or sewing attached to the mesh material and then the hard closure material attached along the periphery of each opening to be covered by the interlocking elements with optionally along the perimeter of covered Opening existing fabric material contact. Thus comes to solving the mounting task a complete adhesive closure tape used, consisting of interlocking elements and Corresponding Fluff, what the known solution is difficult and expensive can be in the production and assembly.

A solution, network material as flyscreen LABEL FOR immediately with hooks Hart closure material, without additional fixation means affixed to them, shown already in the US-A-3753458. dimensioning the head diameter of the interlocking elements is chosen so that it is always larger than the mesh size as measured by the Outer periphery of the mesh. This implies that the mutual distance the interlocking elements must be spaced greater than the Mesh size of the network, so that it is not possible that one or longer reach than one interlocking element per stitch engaged can. The latter reduces the Verhakungswahrscheinlichkeit so that the flyscreen unintentionally anyway in the known solution can be detached from the fastening tape.

Starting from this prior art, the invention has the task based on a cost-effective and safe in the entanglement Fastening device, consisting of a grid with individual Mesh and at least one fastening strap, with a plurality of interlocking elements for fixing the lattice on the fastening tape to further improve that Verhakungswahrscheinlichkeit the grid is raised to the fixing belt.

This object is achieved in that the distance the interlocking elements each longitudinal rib is such selected from each other that one to three interlocking elements per mesh mosquito net in Engagement come and that the spacing of the longitudinal ribs and the Transverse rows from each of the mesh size of the fly screen corresponds. With the application of an adhesive tape made of plastic the interlocking elements as part of the manufacturing process such are arranged in longitudinal and transverse rows, the spacing of the Longitudinal rows from each of the mesh size of the fly screen corresponds, so that the spacing of the hooking elements from each other can be selected such that one to three interlocking elements per loop the grille engage. In this case, the mutual distance selected independently of the interlocking elements in a longitudinal row be each other on the distance of the longitudinal rows, implying an adjustment the arrangement of the interlocking elements to different Geometries of grids allowed. This greatly improves the Verhakungswahrscheinlichkeit.

The arranged in longitudinal rows interlocking elements can be divided into cost-effective manner from arranged on the plastic tape longitudinal ribs obtained in which these divided into incisions that the define respective interlocking element, be stretched in one direction.

The interlocking elements themselves are preferably arrow-, pointed or harpoon-shaped to allow easy penetration into the formed by the mesh structure of the mosquito net to ensure. The invention of an exemplary embodiment is explained in more detail will.

The single FIGURE of the drawing shows a schematic incomplete represented View of a window frame with an inventive means of a Plastic adhesive tape attached flyscreen.

The plastic adhesive tape 1 of the invention comprises plastic longitudinal ribs 3, the are divided so that each 1, 2 or 3 resulting from the subdivision Hooking 5 hook into one stitch 7 a fly screen. 9 The manufacture of the longitudinal ribs 3 having plastic adhesive tape and the subdivision of the longitudinal ribs 3 to form the engaging elements 5 is happening according to the method disclosed in DE 22 13 686 C3 process. On said Patent is incorporated herein by reference. However, it should be taken into account, that the spacing of the longitudinal ribs 3 is chosen from one another so as the Mesh size of each mosquito net 9 corresponds.

In experiments plastic adhesive tapes 1 were prepared, whose hooking 5 adapted to an arrowhead-shaped and the other harpoon shaped were. Both embodiments of the hooking 5 showed a slight Penetration into the formed through the mesh 7 lattice structure of the respective Mosquito net 9, and thus a fast and safe hooking. Basically, but also another form of interlocking elements 5, for example, a mushroom-like Training of interlocking elements 5, are selected.

To fasten the mosquito net 9 that was produced as stated above - Plastic adhesive tape 1 on the side facing away from hooking 5 in at known manner and self-adhesive around a window frame 11 stuck. The flyscreen 9 was cut to the dimension of the window frame 11 and with its edges pressed on the plastic adhesive tape. 1 there has shown that even the plastic adhesive tape 1 whose hooking 5 each longitudinal rib 3 were designed such that a respective interlocking element 5 per Stitch 7 mosquito net 9 engages, shows sufficient adhesion had thereby had the advantage that the flyscreen 9 very quickly was appropriate because it was not necessary, several interlocking elements 5 to allow intervention in a stitch 7 of the fly screen. 9

The schematic view of the single figure is for the purpose of better illustration the subject matter of the invention slightly deviating from Plastic adhesive tape used in practice 1 and held therein flyscreen shown. 9 The band longitudinal direction of the plastic adhesive tapes used in practice 1 extends parallel to the longitudinal direction of the fly screen 9, which Stitches 7 are formed rectangular as a rule, in each case the longer Sides of each rectangle are oriented in the longitudinal direction of the fly screen. 9 The plastic adhesive tape 1 are themselves perpendicular to the longitudinal ribs 3 located transverse rows of interlocking elements 5 just so arranged that they each extending at an acute angle to the longitudinal edge of the fly screen. 9 This is not shown in the figure during the transverse rows of production engineering conditionally. The hooking elements 5 are formed by the plastic longitudinal ribs 3 divided by flat knife to form incisions be and the plastic adhesive tape 1 then stretched to a draw bench is to give the separated by a distance hooking 5 form. An arrangement of the transverse ribs in such a way that they also on the plastic adhesive tape 1 to fixed end flyscreen 9 form an acute angle form, prevents the formation of predetermined breaking points during stretching of the plastic adhesive tape 1. Here, the respective angular degrees this acute angle from Degree of strain-dependent.
