Description

The invention relates to a fabric with weft wires. In particular, it relates to a full metal fabric with weft wires.

Tissues, in particular metal mesh, are used for ever more diverse tasks. One of the most sought-after uses recently is that of facade cladding for buildings. Often, separate objects are placed on fabric. In the case of façade drapery, these may be, for example, support bars with LEDs or other light sources that are either aligned to illuminate the tissue or glow away from the tissue. In other applications, water pipes may be attached to the fabric, for example to achieve a decorative effect with water bubbling down the fabric. Furthermore, decorative twine, speakers and a variety of other items may be attached to the fabric.

The attachment of the articles to the fabric is not always easy and often requires a lot of working time, which makes a fabric provided with items quite expensive in the installation. In most cases, it is attempted to place an article to be attached to the tissue either directly on the tissue and then fix it with attachment wires. If the object is not intended to lie directly against the tissue, it has hitherto been regarded as unavoidable, first a holder on the To fix tissue that protrudes outwards. At its protruding end then the actual object can be attached. All previously known methods are therefore relatively expensive.

The invention has for its object to provide over the prior art, an improvement.

This object is achieved by a fabric according to claim 1. The wire in the fabric is particularly well suited due to its inherent strength of a wire to attach objects of any kind. Thus, both in a fabric which has no metal components in addition to the wire, as well as in a full metal fabric, the weft wire can be advantageously selected for this task. While conventional weft wires extend at least substantially one-dimensionally, the invention enables a considerably easier connection of objects to the weft wire. By targeted shaping of the crimped area on the weft wire, it is possible in particular to create wire areas which are particularly well suited for clipping on an object or at least are more easily accessible and accessible for manual fastening.

The threads or wires may be made of any materials. However, preference is given to metal or plastic. Depending on the application, monofilament or multifilament wires are suitable.
A fabric with a bent wire for carrying articles through a process space is out of the EP 0 478 925 A1 known. An object that is to be transported through the process space of a machine is placed on the woven process belt. After passing through the process space, the object is removed.
The EP 1 428 458 A1 discloses a vandalism resistant metal fabric.
In the DE 25 32 908 A1 An electrically woven matrix is disclosed. At certain points lines are not included in the entanglement, but executed in the form of a loop. The loops are severed and can then be connected to leads of circuit elements with the circuit elements mounted on a baseplate.
The US 2002/0107569 A1 time to create a metal mesh by screwing spiral wires,
In the EP 1 486 598 A2 a metal fabric with integrated light-conducting bodies is disclosed. Such a trade can be used architecturally, for example, as a room divider.
The DE 33 32 536 A1 shows for decorative purposes, a textile structure in which electrical lighting fixtures are mounted according to any pattern, which are connected for the purpose of lighting on the textile provided electrical lines with a power source switchable.
Other metal fabrics are for example the US 4,554,953 B , of the US 4,249,653 B , of the CN 2416129 Y or the WO 03/031292 A2 refer to.

The invention has for its object to provide over the prior art, an improvement.

This object is achieved by a fabric according to claim 1. The wire in the fabric is particularly well suited due to its inherent strength of a wire to attach objects of any kind. Both in a fabric which has no metal components in addition to the wire, as well as in a vollmetallemen tissue thus the weft wire can be advantageously selected for this task. While conventional weft wires extend at least substantially one-dimensionally, the invention enables a considerably easier connection of objects to the weft wire. By targeted shaping of the cranked area on the weft wire, in particular wire areas can be created which are particularly well suited for clipping on an object or are at least more accessible and accessible for manual attachment.

The threads or wires may be made of any materials. But is preferred metal or Kunstsoff. Depending on the application, monofilament or multifilament wires are suitable.

The offset in the weft wire can be in particular U-shaped. A U-shaped crank is particularly easy to produce by machine and can be a bracket arise from the non-cranked part of the weft wire protrudes. This is particularly suitable for the fact that objects are attached to it.

The above results in particular extent if the offset has at least two, in particular four, right angles. Thus, in particular during the weft wire first design erfölgen equal to a right angle, so that the weft wire is led out perpendicular to its remaining course direction of the tissue, there with two more right angles to a U-shape, is bent and then again with dips into the tissue at a right angle.

Regardless of its exact form, it is also advantageous that the offset protrudes from the tissue. It is thus easier to access for both manual and machine connections.

The extent to which the bend protrudes from the tissue depends on numerous circumstances. Thus, first of all, it is important how stable the weft wire is and which load it should remove in the operating state. The designated function may also provide appropriate dimensions. This is the case, for example, when carriers for light sources that illuminate the tissue are to be arranged at the tips of the protruding cranks. At a given light emission spread angle the light sources can illuminate a large area of the tissue, there may be a fairly large required distance to the tissue plane. Thus, it can be advantageous in many cases if the offset leads the weft wire farther out of the tissue than the distance between two chains, in some circumstances even more than twice the distance between two chains.

From a manufacturing point of view, it is advantageous if the offset lies in the course of the weft wire, ie between two chains and not at the edge of the fabric. If the crimp is in the tissue, both the leg of the weft wire, which leads out of the fabric, as well as the one, which leads the weft wire back into the fabric statically supported on each Next chains. In contrast, the cranking would easily become one. Twist under load tend to tilt when placed on the edge of the fabric.

The fabric is particularly stable when the bend is between two immediately adjacent chains.

In order to store and transport a tissue of the type proposed in front of its final place of use space-saving and easy to handle, it is proposed that the cranked weft wire can be rotated about an axis defined by its part located in the tissue and thus laid quite flat on the tissue. In this way it is possible to roll up the fabric like a conventional fabric. When unrolling the crank can be laid flat and rolled into the roll without leading to a too large volume increase of the fabric roll

It is understood that the tissue can already be used advantageously with a crank. In particular, however, it can also have a multiply cranked weft wire and / or several cranked weft wires. In this case, the cranks along the one weft wire, as well as we, the several cranked weft wires may be evenly spaced. In both ways, the carrying capacity for objects is increased significantly in a simple manner.

In order to be able to fix two cranks at an angle to each other and / or to the tissue after installation of the tissue, it is proposed that a tensioning thread is provided for this purpose. The tensioning thread can in particular lead along all the cranks of the fabric, which are lined up linearly to each other, so that if necessary, a plurality of tensioning thread is provided. Ideally, each offset has an attachment with a tensioning thread. After installation of the fabric then only the individual cranked weft wires must be rotated or bent into their desired position, if then the tensioning thread is attached to all Krüpfungen and the tensioning thread is particularly fixed outside the fabric or at the edge of the fabric as possible under tension , the cranks are protected from unwanted rotation about their uncut portions in the tissue. Furthermore Increases such attachment by means of a tensioning thread, the carrying capacity.

It is understood that the object underlying the invention is also achieved by a method according to claim 13. It is immediately apparent that such a fabric manufacturing process results in a fabric of the type described above. It is machine easily possible to perform the crank within the fanned Celts, so that the actual weaving process by the crank in the weft wire is completely unaffected. In this case, the bend can easily lead the weft wire almost as far out of its axis as in the loom, the chain is fanned out. If, for example, the fan dimension in the loom is 20 cm, it is readily possible to set the offset of the weft wire to 19 cm.

Because a fabric described above is used as the basic structure for supporting an article separate from the fabric, it is proposed that the article be worn on the crotch. It has already been explained that the offset is particularly easy to access for securing the objects and, due to the possible spacing to the tissue plane, brings with it further advantages, for example when the article has an electronically controllable light source which is to be used, for example to light the tissue.

After the already explained above, the object also achieves a method according to claim 14. In this case, a full-metal fabric is particularly suitable as building hangings. This can also be used particularly advantageously with respect to its light reflexes as soon as networked light sources, in particular networked LEDs, are provided, which reproduce photos or films via control electronics. If the light source carriers are merely clipped on the cranks, that is to say are fastened to them via a latching mechanism, the later replacement of the light source carriers is also particularly easy if they should be defective once.

In addition, according to the already explained above, the object also achieves a method according to claim 15. A tissue rolled up in this way can then be transported in a particularly space-saving manner to its later place of use, for example to a building whose curtain is to form it. After unrolling the cranks can then be pivoted back to the desired position relative to the tissue plane.

FIG. 6

the side view FIG. 4 with the cranked weft wire in an unfolded and in a flat position:

The metal fabric 1 in the FIGS. 1 to 6 consists essentially of metallic warp threads (exemplified by 2, 3) and conventional weft wires (exemplified by 4, 5).

However, the metal fabric 1 deviates from a conventional fabric in that at those points where weft wires 4, 5 would continue to be located at regular intervals in a conventional fabric, here are two bent weft wires 6, 7 in the fabric. The cranked weft wires 6, 7 are like the her, conventional weft wires 4, 5 integrated into the fabric 1 and are thus held by the warp threads 2, 3.

In the course of each cranked weft wire 6, 7, however, the weft wire is bent at a first point 8 (shown only by way of example on the weft wire 6) by 90 ° and leads out of there from a tissue plane 9. In its course 10, the weft wire 6 is slightly curved, but it leads continuously approximately at right angles to the tissue plane 9 away from this.

At a clear distance from the tissue plane 9, the cranked weft wire 6 is again bent at a second point 11 substantially at right angles and now proceeds essentially parallel to its original course 12 and to the tissue plane 9. However, before it has bridged a field width 13 between the adjacent chains 2, 3, it is at a third point 14 in turn bent by 90 ° and leads next to the course 10 parallel to this in a course 15 (the outgoing course 10 obscuring) again Tissue plane 9 back. There, the weft wire 6 is again bent at a fourth point 16 by 90 ° and now continues its original course 12 in the rest of the tissue.

At the second right angle 11 and at the third right angle 14, the weft wire 6 is not simply bent over - as at the right angles 8 and 16 - but also slightly bent to the extent that it turns in the transverse direction according to FIG Figures 2 . 4 and 6 an apparent U-shaped groove 17 results. In each groove 17, an at least partially translucent tube 18 is pressed. The tubes 18 are equipped with light emitters, preferably with LEDs. These can be individually switched on and off via a central control cable to the LEDs or to other electronic components or other light emitters can be accommodated inconspicuously in the tubes 18 and so for example led to the edge of the fabric 1.

In this way, the metal fabric 1 with the help of the LEDs in the tubes 18 have been deliberately lit static and dynamic. Preferably, light-emitting diodes or other light emitters in the colors red, green and blue (preferably in the ratio 2: 2: 1) are present so that the fabric 1 can be illuminated in a wide variety of colors. With a sufficiently large ratio of the observer distance to the fineness of the grid of the lighting means or of the carrier tubes 18 and supporting cranks 10, 17, 15 required for this purpose, a static or moving image can thus be generated for the viewer.

It can be seen that the cranked weft wires 6, 7 can easily be pivoted about their areas 12 extending in the woven fabric 9 almost up to a right angle, ie up to a position in which the brackets 21, 22 hub too flat on the rest Rest tissue. Such a position is in FIG. 6 clarified. The U-shaped bracket head 17 carries the tube 18 with the LEDs in an eye-folded position of the bracket 21 and can easily be pivoted together with this along a pivoting path 20 in a transport position quite flat on the tissue plane 9 (17 ', 18'). In this position, the entire fabric 1 can be rolled up like a conventional fabric and despite the protruding bracket 21, 22 of the cranked weft wires 6, 7 results in only a small increase in volume of a fabric roll.

In order to fix the support brackets 21, 22 in their swung-out position for operation, two tension side 23, 24, 25, 26 are attached to the fabric 1, which each lead to the bracket 17 and there are also fixed. The tension cables 23, 24 and 25, 26 form in relation to the tissue plane in the lateral view (see FIG. FIG. 2 . 4 ) a triangle, so that a deflection of a support bracket 21, 22 or clamp strap 17 immediately sets one of the tension cables 23 or 24 or 25 or 26 under train and is thus held in the unfolded position. For fixing the tensioning cables 23, 24, 25, 26, a guide groove is provided on the bracket 17, preferably as in FIG Fig. 5 pictured in the middle of the temple.

In the unfolded position, the respective light sources in the support tubes 18, when suitably designed, cast a large cone of light (marked by reference numerals 27) against the tissue 1. The tubes 18 can easily be rotated about their longitudinal axis (represented by the twisting arrow 28) ), so that the light cone 27 of the light emitter can still be individually adapted to each support tube 18. In this case, the clamps 17 may be designed so that they securely fix the tubes 18 in their orientation for operation already by the mere latching or Einklemmkraft.

In detail, the chains 2, 3 are each formed as a group of three grouped wire ropes.

It should be noted that the tissue view in the Figures 1 and 2 can only represent a section of a larger tissue. Above all, the invention makes sense in such tissues, in which in each case a filament tube 18 of at least two cranks 21st and 22 is held along a weft wire 6 and 7, respectively. However, the invention is not limited to such applications.

The exact attachment of the tubes or other objects separated from the tissue at the top of the U-shaped support brackets 21, 22 can be done in many ways, for example, in addition to the shown entrapment or latching by small metal wires, plastic clips or other means.

Essential for the invention is that a continuously producible tissue from the tissue plane protruding support structures, namely the cranked bracket having.

It should be noted that the tension cables fulfill their function not only when they each connect a carrying handle directly to the rest of the tissue, but also when tension cables are mounted between the support brackets, then only one, preferably two. Bracket must be fixed in its swing angle. For this purpose, in turn, a tensioning cable can be used, which at these points in each case leads from the tensioning bow to the rest of the tissue or to the edge of the tissue. The tension wire ropes can be fixed in particular on the edge of the fabric on local support rods under tension.

In use, the tissues of the invention can be placed in a variety of sizes and used meaningful, starting with a small decorative tissue paintwork, for example in window size up to curtains for entire building facades, which can even extend over entire skyscrapers, where - as already indicated above as objects to be carried tubes use Einden, which are fed via a multimedia control electronics specifically with Ström, so that integrated into them Light sources emit colored light either in the direction towards the tissue and / or in the direction away from the tissue. The first variant is particularly suitable for dipping the fabric in color effects that can change over time. In particular, the second variant is suitable for presenting a static and / or dynamic image to a viewer who is far away in the case of a correspondingly dense resolution of the light sources. For example, commercials or art films can be viewed in this way on a building facade.
