Embodiment Construction

[0031] [31] In general, the present invention relates to rollable curtain-type devices cooperating with drive means for moving the curtain between an open position and a closed position. It is important to point out that the curtain can be wound around a common shaft with the drive. Curtains are generally used to close a door, window or any other opening in a wall, to cover a swimming pool, a space such as a corridor, to form a shelter such as in front of a window, and the like. Of course, this list is limited.

[0032] [32] Within the scope of the present invention, the term "curtain" includes, where appropriate, any apron or planar surface that can be wound around a shaft, said apron or planar surface consisting of an at least partially soft, , semi-rigid material, or with one or more reinforcements such as tarpaulins, plastic straps, metal mesh or sheet metal, frames, etc.

[0033] [33] It is necessary to point out, however, that a flexible curtain formed, for example, of...

Abstract

The invention relates to a curtain device mounted on a shaft (2) about which said curtain (1) can be wound to an open position and unwound into a closed position, a drive wheel (7) fixed coaxially to said shaft (2) and cooperating with said curtain (1) such as to displace the latter between said two positions. The device comprises an oblong flexible control body (11), cooperating with the drive wheel (7), said body (11) being embodied to permit the displacement of the curtain (1) between the open position and the closed position thereof, independently of the slack formed in the curtain (1) and to be able to be displaced along at least one of the lateral edges (4) of the curtain (1) and act upon the region (8) of the latter as opposed to that arranged on the shaft (2).

Description

technical field [0001] [01] The present invention relates to a curtain device mounted on a shaft around which the curtain can be wound towards an open position and from which it can be unrolled towards a closed position, a Drive wheels are preferably secured coaxially to said shaft on either side of the curtain and cooperate with the curtain to move the curtain between said two positions. Background technique [0002] [02] Devices of said kind are known, in particular from documents US 5655591, US 5392836, US5353859, US 4690194, DE 3245009, WO 99 / 19590 A, GB 1588438 A, DE 19820933 A and EP 1298264 A, which The curtain is required to be taut throughout its travel between its open position and its closed position. The consequence of this requirement is that due to the necessity of springs, transfer pulleys, deceleration systems, etc. - which generally require fairly fine adjustments to function well, are subject to severe wear and require frequent maintenance especially when ...
