ES2349226T3 - WINDING FOR WINTER OR SIMILAR GARDENS. - Google Patents

Abstract

The tensile bands used to apply tension to the sun-blind fabric (5) are elastic over at least part of their length section. The sun-blind fabric is unwound from or wound-up onto a rotary shaft (1) and is guided by lateral guide rails (9). Tensile bands are attached to the front end (4) of the fabric or to a drop-out tube (7). Tensioning devices for making the fabric taught are also provided.

Description

The invention relates to a canopy for winter gardens or the like comprising a winding tube of the rotationally actuated fabric, comprising a canopy fabric, lateral guide rails for the awning fabric and braces acting on the front end of the awning fabric or in a loading tube, as well as tension devices for the awning fabric, the straps being elastically configured to exert tension on the awning fabric at least by sections in the longitudinal direction. A similar awning for winter gardens is known from DE 4 005 963 A1. EP 0 736 642 B1 describes an awning with tension means in the form of rubber cables.

In the case of rolled awning, the winding diameter of the braces is greater than with rolled awning even as the same fabric winding. To compensate for the different paths produced by the different winding diameters, tension elements containing spring elements are usually used. Similar spring elements condition a considerable assembly expense and increase manufacturing costs.

To remedy this, according to DE 100 33 419 it is planned to transport the awning fabric in the direction of deployment on its own rigid thrust bands.

The invention aims to allow a construction without tension elements, keeping the braces, which regardless of the position of unfolding of the awning fabric guarantees a tense and optically pleasing seat, having to avoid too intense deviations in the case of applying forces of impulse type, as due to gusts of wind.

This objective is solved according to the invention because the braces are made, for example, of a fabric or net that behaves elastically only until a certain elongation and after exceeding this elongation is essentially inelastic. Therefore, the awning in the unfolded state may extend rigidly due to a blockage of its gear or motor and in the case of wind loading or in the case of another type of loading results in a very well tensioned fabric.

In this case it can be advantageously provided that the braces are mounted with pretension, so that in each case an anchoring effort is exerted on the awning fabric.

By means of the solution according to the invention, the need for additional tension elements is suppressed, since the braces themselves are spring-shaped in an elastic manner longitudinally over the entire length or by sections.

The invention is explained in detail below by means of a preferred embodiment in conjunction with the drawing. In this case they show:

A winter garden awning shown in the drawing comprises a winding tube of the rotationally actuated fabric with a fabric winding 2 that can be operated by rotation in the direction of the double arrow 3, and for folding in the direction of the upper partial arrow in fig. 1st fig. 2 and for deployment in the direction of the lower partial arrow in fig. 1st fig. 2.

The front end 4 of the awning fabric 5 is fixed in a weatherstrip groove 6 of a loading tube 7, which is guided on each time a lateral sliding piece 8 in lateral guide rails 9.

On each sliding piece 8, an elastic strip 10 acts, which deflects 180 ° in the area of the outer end of the guide rail 9 by means of a bypass roller 11.and which is connected with the sliding piece 8 or the load tube 7 through a weatherstrip 12. In the area of the inner end of the guide rail 9, a second bypass roller of 90 ° 13 is provided, by means of which the strip 10 is driven in bypass and winding rollers arranged laterally in the fabric winding tube, with which the inner end of the braces is fixedly attached, such that in the case of an elongation of the fabric winding tube 1 in the direction of deployment of the straps 10, exerts a tensile force on the sliding parts 8 and therefore on the loading tube 7 and correspondingly on the awning fabric 5.

The elastic straps 10 are mounted with pretension, so that a tension of tension is always applied on the awning fabric 5 and this is therefore held taut.
