Benefits of technology

[0005] The problem solved by the present invention is to create an adjustable awning or canopy with a canvas cover, with which large areas can be shaded and at the same time the canvas cover is held in tension with a simple construction.

Problems solved by technology

For larger surfaces, however, this type of blind is not suitable, because the articulated arms sag too much and very large leverage forces act on the attachment devices.
A disadvantage of this construction is that, because of the windup rollers located at the ends, the entire length of the shaft is not available for winding up the canvas cover.
The applied forces can deform the shaft, so that the canvas cover can no longer be rolled up smoothly on the shaft.
Therefore, the canvas cover itself can become damaged.
One sided unwinding is not possible.

Embodiment Construction

[0030] In FIG. 1, an awning or canopy comprising a canvas cover 1 is shown, which is rolled onto a rotatable canvas cover shaft 2. The canvas cover shaft 2 is held at its ends by two vertical supports 3a, 3b. On the support 3a, there is a windup shaft 4 that extends parallel to the canvas cover shaft 2. The windup shaft 4 is at a distance from the canvas cover shaft 2. The windup shaft 4 and the canvas cover shaft 2 are held by a common holder 5 that is fixed to the support 3a. A holding element 6 carries the windup shaft 4 on the end away from the support. The holding element 6 is connected to the holder 5 by connecting elements 7, so that the windup shaft 4 is held stably supported and can rotate easily. Together with the connecting elements 7, the holding element 6 and the holder 5 form a cage that encloses the windup shaft 4.

Abstract

An adjustable canopy or awning includes a canvas cover which is connected to at least one cable pull, can be rolled onto a canvas cover shaft that is rotatably supported between two supports and is connected to a drive mechanism. The cable pull can be rolled onto a separate windup shaft and the windup shaft is driven by the canvas cover shaft. The canvas cover can be unrolled from the canvas cover shaft in opposite directions or two separate canvas covers and canvas cover shafts can be provided between the supports.

Description

BACKGROUND OF THE INVENTION [0001] The present invention relates to an adjustable canopy or awning comprising a canvas cover which is connected to at least one cable pull and can be rolled onto a canvas cover shaft that is rotatably supported between two supports and is provided with at least one drive mechanism. [0002] Blinds, canopy or canvas cover arrangements are known in which a canvas cover is attached to a rotating shaft so that the canvas cover is completely fixed at one edge on the shaft. On the opposite edge of the canvas cover there is an emerging profile on which articulated arms engage. If the canvas cover is unrolled from the shaft, then the articulated arms pivot out and tension the canvas cover between bars carried by it and the shaft. For larger surfaces, however, this type of blind is not suitable, because the articulated arms sag too much and very large leverage forces act on the attachment devices. [0003] Furthermore, canvas covers or canopies that can be unrolle...
