Description

The invention relates to a shading with a rotatably mounted cloth shaft, from which a cloth is unwound, wherein a base side of the cloth forming side is fixed to the fabric shaft.

Such shades developable from a tube are known. A disadvantage of the known shading is that the cloth has too low a tension and sag the edges of the cloth.

From the document US 2014/0060757 A1 For example, an awning with a cloth which can be unwound from a tube is known, wherein one or more wires or cables are fastened along the cloth.

From the document DE 10 2006 034 428 A1 an awning with a developable from a fabric wave cloth is known, wherein the cloth has side seams, in which tension elements, in particular fiber-reinforced bands are incorporated.

From the document DE 10 2007 034 728 A1 an awning with a developable from a fabric wave cloth is known, wherein the cloth in the region of the seam has tension strips, in particular that it is in the tension strip to elastomers, in particular rubber.

The object of the invention is to provide a shading whose cloth has sufficient tension and in which sagging of the cloth edges is reliably avoided.

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

When shading with a rotatably mounted cloth shaft from which a cloth is unwound, wherein the base side of the cloth forming side is fixed to the fabric shaft, are directed to extend in the extension direction edges of the shading in the extension direction tensioning means, wherein the clamping means each by a Hose, in particular by a woven tube are formed, which deposits flat when winding on the fabric shaft.

The arrangement of clamping devices on the edges of the shading, the cloth can be applied in the region of the edges with the required voltage. As a result, in particular a sagging of the cloth edges is counteracted. Another particular advantage is that the clamping means are formed by a hose, in particular by a woven tube. Such a woven tube can thus be, in particular, a textile fabric.

Such as a hose, in particular designed as a woven hose tensioning means combines the extremely positive for the operation of a rope on the one hand and on the other hand a belt. In that region of the clamping device, which are guided under a tensile force, for example, over deflectors or pulleys, you are under tensile force hose with a circular cross-section, which can be performed easily and without high wear on deflectors or pulleys and the like. When winding the shading on the fabric shaft, the tensioning means formed by a hose lays flat, so that the clamping means can be easily wound up with the cloth on the fabric shaft, without causing objections.

Particularly preferably, the clamping means is formed by a woven tube. A woven hose combines a high tensile strength in the longitudinal direction of the tensioning means with a high flexibility of the woven hose perpendicular to the longitudinal direction, so that such a woven hose can be easily laid flat and wound while at the same time such a woven hose under tension in the longitudinal direction with a circular Cross section represents.

The operation of this tensioning means formed by the tube is understandable when one thinks of a wound fire hose. Rolled up forms such a tube in several layers over one another wound package whose width corresponds to half the circumference of the hose. However, the unwound region of the tube is such that this region has a circular cross-section.

Likewise, the invention according to the invention by a hose, preferably a woven tube formed clamping means of Dreieck shading behaves. In this case, a woven tube shows particularly advantageous properties due to its strength in the longitudinal direction and its flexibility perpendicular to the longitudinal direction. The term longitudinal direction refers to the Gegenzugmittel as such.

The extension direction indicates the direction from the fabric shaft to the front end of the Dreieck shadattung. With the front end of the triangular shading is meant that end of the triangular shading, which has the maximum distance in the extension direction of the fabric shaft at fully unwound cloth.

The shading is preferably a triangular shading, the cloth having a triangular basic shape and a side forming the base side of the triangular cloth being fastened to the fabric shaft.

By means of the clamping means, the edges of the triangular cloth are tensioned in the direction of the front tip of the triangle in the extension direction. Due to the configuration as a triangle, the tensioning means of each side lays down during winding in the form of a helical line on the fabric shaft. Throws or thickening thus arise when winding the triangular cloth with the arranged on the edges clamping means not.

In a preferred embodiment, the edges of the shade, which are directed towards the tip in the extension direction, are lined, the tensioning means being arranged in the hems. By arranging the clamping means in hems at the edges of the cloth shading, it is ensured that the necessary tension can be applied to the cloth edges with the clamping means.

Preferably, the clamping means of the first edge is connected to the clamping means of the second edge and guided over one or more deflections.

In particular, the clamping means of the first edge and the clamping means of the second edge may be formed as one-piece clamping means.

In this case, the first end of the one-piece clamping means is attached to the base of the cloth and / or cloth shaft at the first corner of the cloth, and the second end is also at the other end of the base to the opposite corner of the cloth at the base of the cloth and / or. or attached to the cloth shaft. In the case of triangular shading, the first end of the one-piece chuck is attached to the base of the triangular cloth and / or cloth shaft at the first corner of the triangle, and the second end is also at the other end of the base to the opposite corner of the triangle at the bottom of the triangular Cloth and / or attached to the cloth shaft. By such a one-piece clamping means, it is ensured that when applying a tensile force on the clamping means in the extension direction of the triangular shading on both edges of the same cloth over the tensioning means is applied.

The clamping means arranged on the edges is fastened to the base side of the cloth on the cloth and / or on the cloth shaft. Such attachment can be done in particular by sewing and / or gluing and / or welding.

An extension profile is preferably arranged on the front end of the drape in the extension direction, on which directly or indirectly at least one traction means engages in the extension direction. In this way can be applied to the cloth and the clamping means in an advantageous manner, the required tension.

Preferably, the cloth is formed by an isosceles, in particular equilateral triangle.

Preferably, the cloth has a triangular basic shape and it engages at the front end in the extension direction of the triangular cloth at least one traction means in the extension direction. By such a traction means a tensile force in the extension direction is applied to the triangular cloth whereby this is tense. This ensures an optimal cloth level. In particular, such a traction means can also act directly on the clamping means and tension them in the extension direction.

The cloth having a triangular basic shape may have a flattening at its front end in the extension direction. In particular, an extension profile can be arranged on such a flattening of the tip of the cloth at the front end. On the extension profile can indirectly or directly attack a traction device in the extension direction.

Preferably, the clamping means of the first edge is guided over a first deflection and then guided over a second disposed on an extension second deflection and further guided in one piece in the clamping means of the second edge passing over a third deflection. In particular, the first deflection and the third deflection can lie on the same deflection axis and in particular be formed by the same deflection. Alternatively, the first deflection and the third deflection may be on different deflection axes.

In this case, preferably at the first and third deflection at least one traction means in the extension direction attack, whereby the clamping means of the first edge and the clamping means of the second edge are automatically stretched.

In a preferred embodiment, the cloth has one or more transverse struts extending in particular perpendicular to the extension direction. Such transverse struts can be attached to the edges of the cloth, in particular be received in pockets of hems on the cloth edges. By such cross struts, the stability of the cloth is increased in the extended state. When winding the cloth, these cross struts lay one behind the other on the fabric shaft and lie in the wound state parallel to the fabric shaft side by side over the circumference of the fabric shaft distributed.

Accordingly, in the arrangement of a plurality of transverse struts, the cross struts are preferably spaced apart from one another such that they are in the Wind the cloth on the cloth shaft side by side and thus avoid a line-shaped thickening.

Preferably, the cloth has one or more transverse to the extension direction transverse struts, wherein the transverse struts have a bias and set up arcuate in extended shading or triangular particular shading. Such pretensioned cross struts can be used to realize an arcuate installation of the shading or triangular shading in the extended state. In the case of a triangle shading the triangle then forms a spatially shaped triangular section of the surface of a ball due to the arcuate arrangement of the prestressed cross struts. This can be created by the triangular shading a particularly advantageous embodiment.

In a preferred embodiment, the cloth has one or more transverse to the extension direction transverse struts, wherein the cross struts has an excess length relative to the distance of the directed in the extension direction edges of the shading height of the respective cross strut and by means of arranged at the edges of the shading tension means a compressive stress is applied to the cross struts.

Due to the fact that the transverse struts have an excess length in relation to the distance of the edges of the shading directed in the extension direction at the level of the respective transverse strut, a compressive stress on the transverse struts clamped between the tensioning means is automatically generated as a result of the application of a tensile stress on the soot means at the edges of the scarf. As a result of this compressive stress on the cross struts, these are arcuate. Optionally, the cross struts may have an upward bias in the direction of the desired deflection of the cross struts.

Preferably, the roller shaft is driven by an electric motor. For this purpose, the cloth shaft an electric motor, in particular remote-controlled drive exhibit. Alternatively or cumulatively, the cloth shaft may be formed by a spring shaft. In particular, an automatic rolling up of the triangular shading can be realized by a spring shaft. The unwinding of the triangle shading takes place against the spring force of the spring shaft.

Preferably, at least one traction means engages directly or indirectly at the front end of the cloth in the extension direction and acts on the cloth in the extension direction with a tensile force. By such a tensile force, the required tension is induced by the tensioning means in the edges of the triangular shading and tensioned the cloth as a whole in the extension direction. Preferably, a pulling means engaging in the extension direction at the front end of the cloth is fastened to at least one in particular telescopic support. Such a support may in particular have a cable storage system. In particular, such a support can stand vertically and / or be variably adjustable and lockable in its inclination against the vertical. As a result, by an adjustment of the inclination of the support against the vertical, a retightening of the triangular shading possible.

Due to the telescoping of such a particular vertical front support, the inclination of the triangular shading can be variably adjusted. The traction means is preferably formed by a rope. In particular, such a tensioning cable can be arranged on a particularly vertical support. The support may be arranged with a bottom plate and / or sunk in a bottom-side receptacle. This support as a front receptacle and attachment of the triangular shade can have a rope storage system with traction accumulator. In particular, a cable storage system can be arranged with a self-locking crank mechanism. By such a self-locking crank mechanism, the tensioning cable can be tensioned by a slight actuation, due to the self-locking of the crank mechanism, an independent release is reliably prevented. The tensioning cable engages directly or indirectly at the front end of the triangular shading and thereby generates the desired tension of the triangular shading in the extension direction.

Fig. 1 shows the top view of a triangle shading in the extended state with the roller tube 1. The roller tube 1 is rotatably mounted. Furthermore, the cloth 2 with a triangular basic shape can be seen in the plan view. The base 3 of the cloth 2 is attached to the cloth shaft 1. The extension direction is indicated by the arrow 4 in the figures.

The side edges of the cloth 2 have the seams 5, 6. Inserted in the seams 5, 6 of the cloth 2 are tensioning means 7, 8 whose guide or deflection is described below Fig. 3 is explained. By means of the inserted in the hems 5, 6 in the cloth edges of the cloth 2 tensioning means 7, 8, the triangular cloth 2 is stretched in the extension 4, to bring about an optimal cloth level. Furthermore, the cloth 2 perpendicular to the extension direction leading struts 10, which are attached to the cloth edges of the cloth 2 to the hems 5, 6.

The cloth 2 is flattened at the front end and has a small extension profile 9. The front flattened end of the triangular cloth 2 is attached to the extension profile 9. Indirectly via the clamping means 7, 8 engages a traction means 12 in the extension direction 4 at the Ausfahrprofil 9 and biases the cloth 2 in the extension 4. The traction means 12 is fixed to the vertical support eleventh

The support 11 is, as in Fig. 2 represented by the double arrow 12, vertically adjustable. By the vertical adjustment of the support 11, the inclination of the cloth 2 of the triangular shading can be adjusted. The fabric shaft 1 is fixed by means not shown brackets, for example, on a building wall. The cloth shaft 1 is rotatably mounted and the cloth 2 is unwound from the rotatable cloth shaft 1.

The leadership of the clamping means 7, 8 of the cloth 2 is based Fig. 3 in the enlarged view of detail A after Fig. 1 recognizable. The tensioning means 7 of the left-hand cloth edge of the cloth 2 and the tensioning means 8 of the right-hand cloth edge of the cloth 2 are made in one piece and are first guided in each case via a first deflection 13 and then via a second deflection 14. The fact that the clamping means 7, 8 are integrally formed, there is an optimal application of force and tension of both edges of the cloth cloth 2 in the extension 4. The integrally running clamping means 7, 8 is formed by a woven tube. Such a woven tube has the advantage that it is placed in a circular manner under a tensile force and, accordingly, can be deflected over the deflections 13, 14 without twisting.

The traction means 7, 8 is deflected twice over the first deflection 13 and over the second deflection 14, so that overall a symmetrical design is formed, as in Fig. 3 is recognizable. At the first deflection 13 engages in the extension direction 4, the traction means 12 which is attached to the support 11. The support 11 has a cable storage for the traction means 12. Furthermore, the support 11 has a clamping system by means of which the traction means 12 can be tensioned in the extension direction 4. The two deflections 13, 14 are formed by snap hooks.

In the cloth shaft 1 is a spring wave, ie that by applying the tensile force by means of the traction means 12 in the extension towards the front tip of the triangular cloth 2 this against the torsional force of the spring shaft 1 in the extension 4 can be unwound. As soon as the traction means 12 by applying the clamping system a lower force on the cloth in Extending 4 applies, ie that by a user by pressing a yielding of the traction device 12 is carried out by the turning back of the spring shaft 1, an automatic winding of the cloth 2 on the fabric shaft 1. When winding the cloth 2 on the fabric shaft 1 put through the Fabric tension formed clamping means 7, 8 in the form of a helical line flat on the fabric shaft 1, so that warping and wrinkles are avoided. Accordingly, the tensioning means 7, 8 can be wound up in a simple manner together with the cloth 2 on the cloth shaft 1.

Fig. 4 shows the section B - B after Fig. 1 through the strut 10. The cloth 2 has as in Fig. 1 is shown, extending perpendicular to the extension direction struts 10, which are attached to the side edges in the seams 5, 6 of the cloth 2. The struts 10 have a bias, so that they set up arcuate, as in Fig. 4 is recognizable. As a result, an arcuately erected Dreieck shading is created in the extended state.
