Description

The invention relates to an awning with a rotatably mounted in a housing roller tube, from which a cloth is unwound, the front end is attached to an extension profile, wherein the Ausfahrprofil is guided on guide rails in the extension direction movable, wherein the Ausfahrprofil means of a Gegenzugmittels in the extension direction means a tensile force is applied and wherein the fabric shaft has at least one section for winding the Gegenzugmittels, which is wound up during extension of the Ausfahrprofils and unwound when retracting the Ausfahrprofils, wherein the Gegenzugmittel is coupled to the Ausfahrprofil and tensioned by means of a spring accumulator.

Such awnings are known. Such awnings, in which the extension profile is guided extendable on guide rails in the extension direction, are used in particular as conservatory awnings respectively interior shading in conservatories.

In order to extend the extension profile and to ensure optimum cloth level for winter awnings and interior shading, it is necessary to apply a tensile force in the extension direction on the extension profile. From the EP 0 595 959 B1 is a clamping device for a flexible, flat cover means is known in which a clamping system for tensioning the awning fabric is arranged in the Ausfahrprofil.

From the DE 20 2013 103 538 U1 is an awning with a Gegenzugsystem known in which the winding portion for the Gegenzugmittel has laterally delimiting cheeks, wherein at least one of the cheeks has an inside projecting bead. As a result, a winding of several rope sections to be avoided one above the other, since such a winding of several cable sections one above the other results in that the live rope slips down and thereby produces an undesirable noise.

The disadvantage here is that even by such a bead, at least a brief winding of several cable sections one above the other and a subsequent slide down the live rope is not completely excluded.

From the DE 93 09 350 U1 an awning for shading conservatories is known in which a Gegenzugmittel is provided in the form of a belt. The belt is guided over several pulleys and twisted several times by 90 °, since the orientation of the winding of the belt on the roller tube is perpendicular to the direction of deflection of the belt at the front end and the clamping system.

From the EP 1 273 734 is an awning with a Gegenzugsystem known in which straps are provided, which are elastically formed in sections, to provide a construction without clamping elements and yet to ensure that the awning fabric has a tight fit regardless of the extended position.

A disadvantage of the known awnings, which have a belt as traction means is that the belt is subject to the necessary twisting a high wear and does not reach a satisfactory service life, but quickly has unsightly fraying and in the worst case can even break.

The object of the invention is therefore to further develop an awning of the type mentioned above, so that the mentioned disadvantages are overcome and the awning has a high reliability and durability.

This object is achieved by an awning according to claim 1. Advantageous developments of the invention are specified in the subclaims.

Particularly advantageous in the awning with a rotatably mounted in a housing roller tube from which a cloth is unwound, the front end is attached to an extension profile, the Ausfahrprofil is guided on guide rails in the extension direction movable, wherein the Ausfahrprofil by means of a Gegenzugmittels in the extension direction means a tensile force is applied and wherein the fabric shaft has at least one portion for winding the Gegenzugmittels, which is wound up during deployment of the Ausfahrprofils and unwound when retracting the Ausfahrprofils, wherein the Gegenzugmittel is coupled to the Ausfahrprofil and tensioned by means of a tension accumulator, it is that the Gegenzugmittel is formed by at least two sections, wherein a first portion of the Gegenzugmittels, which is wound up during extension of the Ausfahrprofils, formed by a belt, wherein a second portion of the Gegenzugmittels is formed by a rope.

The first section of the counteracting means is thus formed by a flat belt with preferably a flat cross section, ie that the belt has a greater width than thickness. The flat cross-section of the belt allows the belt to be rolled up over several layers without the risk of lateral slipping. The second section of the counteracting means is formed by a rope, that is, this second section of the Gegenzugmittels preferably has a round cross-section. As a result, a guide and deflection of the second portion of the Gegenzugmittels via pulleys is easily possible.

The extension direction indicates the direction from the fabric shaft to the front end of the guide rails. With the front end of the guide rails is meant that end of the guide rails, which has the maximum distance in the extension direction of the housing of the awning. The housing of the awning is accordingly arranged at the rear end of the guide rails and can be inserted in particular via corresponding locking pins in the guide rails to allow easy mounting of housing and guide rails to each other. The terms rear and front end of the guide rails are accordingly used regardless of the type of awning and the intended installation of the awning, that is both in horizontal or at a slight inclination extending conservatory awnings or interior shading.

The cloth shaft accordingly has a section for winding the belt, in particular in the form of a belt pulley. Characterized in that that region of the Gegenzugmittels, which is wound on extension of the Ausfahrprofils in the extension direction on the fabric shaft, is formed by a flat belt, the construction of multiple layers of a rope connected to the problem of unwanted noise is reliably avoided. Instead, that area which is wound up during the extension of the extension profile is formed by a flat belt, which can easily be wound up in several layers. It is also no problem that the Gegenzugmittel is under a tensile stress.

The section of the fabric shaft for winding the belt is preferably designed as a belt pulley. Preferably, the portion of the cloth shaft for winding the belt on side cheeks whose distance is equal to or greater than the width of the belt. As a result, lateral slipping of the belt is prevented. Furthermore, the belt is guided by these lateral cheeks and can be wound in several layers one above the other.

A second portion of the Gegenzugmittels is inventively formed by a rope. This second section of the retraction means, which is formed by a rope, is preferably guided over one or more deflection rollers and / or one or more loose rollers in or on the guide rails and / or the extension profile. The fact that this second portion of the Gegenzugmittels is formed by a rope, a guide of the Gegenzugmittels on the required pulleys is easily possible, whereas would result in using a belt in this second section difficulties in the deflection of the Gegenzugmittels and increased wear. These disadvantages are reliably avoided by virtue of the fact that the counter-tensioning means is formed by a cable in the second section of the counter-tensioning means.

Accordingly, it is a particular advantage of the invention that the region of the counteracting means which is wound up during the extension of the extension profile is formed by a flat belt which can be laid over one another in several layers, whereas the second section of the counteracting means which passes over deflection rollers is formed by a rope. A rope, in contrast to a belt easily over deflection rollers can be performed in any way without a problem, for example, by a buckling of the Gegenzugmittels in the longitudinal direction or twisting of a belt or the like could occur, as might happen in a guided over pulleys belt. In particular, by the use of a rope as the second portion of the counter-tension means, which is guided over deflection rollers, the wear is avoided, as it inevitably occurs in guided over pulleys belts.

In a preferred embodiment, the counter-tensioning means is formed completely or in sections by an elastic material and forms a traction accumulator. In this case, the tension accumulator, which serves to tension the counter-tensioning means to apply a corresponding tensile force in the extension direction on the Ausfahrprofil and to produce an optimal cloth state of the awning, in particular in the extended state, formed by an elastic Gegenzugmittel itself. Here, the first portion of the Gegenzugmittels, which is formed by a belt, and / or the second portion of the Gegenzugmittels, which is formed by a rope, be formed of elastic material. It is particularly advantageous if a combination of materials is selected in which the second section of the counter-tensioning means designed as a cable has a higher elasticity corresponding to a lower strength than the first section of the counter-tensioning means designed as a belt. In this case, the belt provided with a lower elasticity and thus higher strength ensures the stability in particular when wind loads occur, whereas the elastic rope introduced in the extended state into the extension profile via deflecting rollers forms the traction force accumulator.

In a sectional or complete formation of the Gegenzugmittels made of elastic material, the Gegenzugmittel simultaneously serves as path compensation, since the Peripheral decrease of the wound on the winding shaft cloth during unwinding and the increase in circumference of the wound up during deployment belt are inversely proportional, but it may happen that any deviations occurring are compensated.

Particularly preferably, the second portion of the Gegenzugmittels, which is formed by a rope, guided over a loose role, wherein the loose roller is kinematically coupled to the spring accumulator.

By such a kinematic coupling of a loose roll, over which the Gegenzugmittel is guided, with the spring accumulator, the Gegenzugmittel is biased accordingly, so that always the required tensile force is applied to the Gegenzugmittel resulting in the desired optimum tension of the cloth, so that the cloth the awning also has an optimum cloth level even when the extension profile is extended and does not sag.

The arrangement of a spring accumulator as traction accumulator can thus be carried out alternatively to an elastic Gegenzugmittel, in particular partially elastic Gegenzugmittel, or cumulatively to an elastic Gegenzugmittel, in particular partially elastic Gegenzugmittel.

The tension accumulator, which serves to apply a corresponding tensile force in the extension direction on the Ausfahrprofil, can thus be formed by the Gegenzugmittel itself and / or by a spring accumulator. By means of this tension accumulator can be compensated in particular the explained distance differences during extension and retraction of the awning between the reeling cloth and the unwinding belt when retracting or vice versa the unwinding cloth and the winding belt when extending the awning. The distance compensation can thus be realized by means of an elastic Gegenzugmittels and / or by means of a spring accumulator.

Particularly preferably, the awning on a symmetrical structure with two Gegenzugmitteln. In particular, the counter-tensioning means can be coupled to one another on the extension profile, in particular both counter-tensioning means can be made in one piece. This means that on both sides of the cloth on the cloth shaft in each case a belt pulley, in particular side cheeks having arranged for winding that portion of the Gegenzugmittels on each side of the cloth, which is formed by a belt. Both Gegenzugmittel on both sides of the cloth further have a second portion which is formed by a rope and which is guided over guide rollers in or on the guide rails and / or the Ausfahrprofil, wherein particularly preferably both Gegenzugmittel are designed in one piece, that within of the extension profile, merge into each other. Preferably, at least one spring store is arranged within the extension profile, by means of which the counter-tensioning means are tensioned. It can also be arranged for each of the two sides of the Gegenzugmittels each have a spring accumulator.

Particularly preferably, the counter-tensioning means are tensioned by a spring accumulator acting directly or indirectly on the counter-tensioning means. The spring accumulator may in particular be one or more tension springs and / or compression spring (s).

Alternatively or cumulatively, the counter-tensioning means are tensioned by a spring mechanism acting directly or indirectly on a loose roller over which the respective counter-tensioning means is guided. In such a spring memory may in particular be one or more tension springs and / or compression spring / s.

In a particularly preferred embodiment corresponding Gegenzugmittel are arranged in a symmetrical structure of the awning on both sides of the cloth, which merge within the Ausfahrprofile and thus coupled to each other, each of the side via pulleys in the Ausfahrprofil in guided Gegenzugmittel each one loose Roller is performed, which acts on the spring memory, so that due to the coupling of the two counter-tensioning means and the arrangement of the spring accumulator on both sides of the cloth, the same tensile force is applied to the Ausfahrprofil, so that there is a symmetrical tensile force and optimum cloth level.

The two portions of the Gegenzugmittels, that is, the first portion of the Gegenzugmittels in the form of the belt and the second portion of the Gegenzugmittels in the form of the rope can be formed by different materials or by identical materials.

By combining different materials, the respective desired material properties can be combined. However, it can also be used Gegenzugmittel in which both the flat belt and the rope and thus both portions of the Gegenzugmittels are formed by the same material. In particular, the two sections of the counteracting means can be formed by a fabric. In this case, both sections of the counteracting means may in particular be formed in one piece by a fabric. This can be created by weaving the countermeans by changing from weaving a flat belt is carried out in a weaving of a rope, so that there is a one-piece woven Gegenzugmittel.

When the awning is designed such that it has a symmetrical construction, a counter-tensioning means can be produced in such a way that, after weaving a first section in the form of a flat belt, a transition to weaving a section in the form of a rope takes place and then finally a transition to Weaving a flat belt is done. By producing such a fabric running in one piece thus the required Gegenzugmittel can be produced in one piece, which then on both sides of the awning cloth each arranged Gegenzugmittel each comprising a portion which is formed by a flat belt and when extending the Ausfahrprofils on the Gurtscheiben to both Sides of the cloth is wound on the fabric shaft, and each having a second section in the form of a rope, which is guided over deflection rollers and loose rollers, wherein engage the loose rollers of the / the spring store.

The two sections of the counter-agent can be formed by a thermoplastic. In particular, the two sections may be coupled together by welding.

Alternatively or cumulatively, the two sections of the counter-tensioning means can be coupled to one another by means of a coupling part, in particular by means of a pressing part.

Further, the two portions of the counteracting means may be coupled together by means of a belt buckle or by interlocking loops. For this purpose, at the respective ends of the sections of both the belt and the rope loops may be formed, which are fixed by pressing parts. By passing one loop through the other loop prior to compression of the pressed part, a permanent connection of the two portions of the counter-tensioning means between the strap and the rope can be formed.

The counter-tensioning means may also consist of a homogeneous woven belt-rope combination in which the transition between belt and rope is fluid.

In this way, in particular, the possibility is given to roll the Gegenzugmittel so far that even the transition region from the belt to the rope and if necessary even beyond the Gegenzugmittel wind up to expand in this way the usable range of Gegenzugmittel. In this case, even a few revolutions can take place with a winding of a section formed by the cable, wherein the unwanted drop of the rope is prevented by the fact that this rests on the already wound flat belt.

In a preferred embodiment, the distances of the coiling retracting means and the unwrapping wipe are opposite proportional and vice versa due to the increase in circumference in the winding of the retraction means and the circumferential decrease in the unwinding of the wipe.

Particularly preferably, the first portion of the counteracting means, which is formed by the flat belt, the same material thickness, as the cloth and / or as arranged on the cloth cloth cavities and / or longitudinal seams.

The term longitudinal seam designates a seam running parallel to the extension direction in the awning fabric, which occurs when the awning fabric is sewn together from several sections. Furthermore, the cloth may have seams sewn around at its outer edges.

An embodiment of the invention is illustrated in the figures and will be explained below. Show it:

1 a perspective view of an awning with Gegenzugmittel;

2 the Gegenzugmittel the awning according to 1 as such.

1 shows a perspective view of an awning with a canvas shaft 1 , From the rotatably mounted canvas shaft 1 is the cloth 3 unwound, the front edge of which in the illustration according to 1 extended extension profile 2 is attached. The extension profile 2 is guided on guide rails in the extension direction movable. For better clarity are in the schematic representation according to 1 neither the housing in which the fabric shaft 1 is rotatably mounted, nor the guide rails on which the Ausfahrprofil 2 is movably guided, shown. In the illustration according to 1 is the extension profile 2 extended, leaving the cloth 3 between extension profile 2 and cloth shaft 1 is stretched.

On both sides of the cloth shaft 1 are belt pulleys 4 . 5 arranged on which the Gegenzugmittel 6 . 6 ' on both sides of the cloth shaft 1 when extending the extension profile 2 is wound up. For the purposes of the invention, the terms counteracting means and traction means are used interchangeably.

In the front area of the awning is the Gegenzugmittel 6 over pulleys 10 . 10 ' . 11 . 11 ' guided and further into the extension profile 2 ushered. There are two stationary pulleys 10 . 10 ' arranged at the front ends of the guide rails, not shown, while on the Ausfahrprofil 2 two together with the extension profile 2 traveling pulleys 11 . 11 ' are arranged, over which the Gegenzugmittel 6 . 6 ' on both sides in the extension profile 2 be brought into it.

The counteragent 6 . 6 ' is designed as an integral traction means such that this on both sides of the cloth 3 runs along and in the extension profile 2 over pulleys 11 . 11 ' is led into it. Within the extension profile 2 is the traction device 6 . 6 ' over two pulleys 7 . 7 ' guided, which are stationary in relation to the extension profile 2 are arranged. Furthermore, the traction means 6 over two loose rolls 8th . 8th' guided, on which on both sides symmetrically arranged spring accumulator 9 . 9 ' attack and thereby a pulling force on the Gegenzugmittel 6 exercise.

2 shows the counteragent 6 . 6 ' according to the awning 1 in a schematic representation. Overall, this is the counter-agent 6 . 6 ' integrally formed and thus engages on both sides of in 2 not shown awning fabric 3 at the also in 2 not shown extension profile 2 at. Because of that in 1 recognizable front pulleys 10 . 10 ' Fixed to the guide rails, not shown, thus a tensile force can be exerted in the extension on the Ausfahrprofil, resulting in an optimal cloth level of the awning fabric 3 results.

As in 2 and in particular in the enlarged view of the detail A is recognizable, is the traction means 6 through two sections 61 . 62 educated. The first paragraph 61 of the traction device 6 is formed by a flat belt, which extends the extension profile on the belt pulley 5 at the cloth shaft 1 is wound up. This is followed by a strap with the belt 61 coupled second section 62 which is formed by a rope. This second section 62 which is formed by the rope becomes as in 2 recognizable by the stationary pulleys 10 . 10 ' continue over the pulleys 11 . 11 ' on the extension profile 2 in the extension profile 2 ushered. The first paragraph 61 in the form of the belt and the second section 62 in the form of the rope of the traction device 6 are welded together in the coupling area. Both sections are formed in the illustrated embodiment by a thermoplastic.

When extending the extension profile 2 there is a winding of the traction means 6 . 6 ' on the corresponding sections 4 . 5 at the cloth shaft. As a result, due to the kinematic coupling, a tensile force in the extension direction on the Ausfahrprofil 2 induced, whereby the Ausfahrprofil 2 is moved in the extension direction and the unwinding of the awning fabric 3 from the cloth shaft 1 he follows.

The coupling of the counteragent 6 . 6 ' with the extension profile 2 takes place as in 1 represented by the fact that the Gegenzugmittel 6 . 6 ' over the fixed rollers 10 . 10 ' at the front end of the guide rails, not shown, and then on the extension profile 2 arranged pulleys 11 . 11 ' be guided into the Ausfahrprofil, so that in this way a tensile force by the Gegenzugmittel 6 . 6 ' can be applied in the extension direction on the extension profile. The counteragent 6 . 6 ' itself is again under the bias of the spring accumulator 9 . 9 ' so that always a corresponding tensile force in the extension direction on the extension profile 2 is applied and an optimal cloth level of the awning fabric 3 is brought about.
