Awning

Abstract

An awning that has a support device, a cloth shaft, a cloth, a lead bar and a drive device. The lead bar can be adjusted via the drive device between a fully retracted minimum position and a completely extended maximum position. The drive device has at least one first arm link which, at its inner end facing the cloth shaft, is mounted via a joint device so as to pivot about a pivot axis. The joint device is designed such that an inclination of the pivot axis relative to the vertical changes depending on the pivoting movement of the first arm link and depending on the distance of the lead bar from the cloth shaft. A control part is provided which is connected in an articulated manner to a first arm link at a first joint and which is connected in an articulated manner to the support device at a second joint.

What is claimed is: 
     
         1 . An awning comprising:
 a support;   a horizontally extending cloth shaft that is rotatably mounted on the support;   a cloth;   a horizontally extending lead bar;   a drive; and   a control part,   wherein the cloth is connected to the cloth shaft in a region of an inner cloth edge and to the lead bar in a region of an opposite outer cloth edge,   wherein the lead bar is adapted to be moved via the drive between a fully retracted minimum position, in which the cloth is wound up as far as possible on the cloth shaft, and a fully extended maximum position, in which the cloth is stretched as far as possible, the lead bar occupying a plurality of intermediate positions between the minimum position and the maximum position during the adjustment,   wherein the drive has at least one first arm link which is pivotally mounted at its inner end facing the cloth shaft about a pivot axis via a joint,   wherein each position of the lead bar is associated with a defined pivot position of the first arm link about the pivot axis,   wherein the joint is designed such that an inclination of the pivot axis relative to a vertical changes depending on the pivot position of the first arm link and depending on the distance of the lead bar from the cloth shaft, and   wherein the control part is connected in an articulated manner to the first arm link at a first joint and which is connected in an articulated manner to the support at a second joint.   
     
     
         2 . The awning according to  claim 1 , wherein the control part is rod-shaped or tab-shaped and has, at one end, the first joint with a first joint axis and at its opposite end the second joint with a second joint axis. 
     
     
         3 . The awning according to  claim 2 , wherein the first joint axis and the second joint axis run inclined relative to each other at an angle in the range of 70° to 90°. 
     
     
         4 . The awning according to  claim 1 , wherein the joint is designed such that the inclination of the pivot axis relative to the vertical is, at least in a partial range of the adjustment of the lead bar between the minimum position and the maximum position greater the further the lead bar is away from the cloth shaft. 
     
     
         5 . The awning according to  claim 1 , wherein, in the minimum position, the pivot axis runs vertically. 
     
     
         6 . The awning according to  claim 1 , wherein the inclination of the pivot axis relative to the vertical is greatest in the maximum position of the lead bar. 
     
     
         7 . The awning according to  claim 1 , wherein, in the maximum position of the lead bar, the inclination of the pivot axis relative to the vertical is in the range of 9° to 35°. 
     
     
         8 . The awning according to  claim 1 , wherein the pivot axis is formed between the first arm link and a bearing part, and wherein the bearing part is pivotally mounted on the support about a tilt axis. 
     
     
         9 . The awning according to  claim 8 , wherein the tilt axis runs horizontally +/−5°. 
     
     
         10 . The awning according to  claim 8 , wherein the bearing part has a console-formed attachment, and wherein the pivot axis penetrates the attachment.
