Canvas shaft holder

Abstract

A canvas shaft holder for an awning having a canvas shaft, on which an awning canvas can be wound. At least one shaft end piece is provided, which is inserted into the canvas shaft in an axial end region thereof, the shaft end piece being connected to the canvas shaft in a force-fitting manner. A pressing part, which is inserted axially into the canvas shaft, is movable relative to the shaft end piece and/or to the canvas shaft in the axial direction of the canvas shaft between a clamping position and a release position. In the clamping position, a radial pressing force is exerted on the shaft end piece. The canvas shaft holder has at least one clamping bar which is guided through the pressing part and the shaft end piece and via which the pressing part is movable from the release position into the clamping position.

What is claimed is: 
     
         1 . A canvas shaft holder for an awning, the canvas shaft holder comprising:
 a canvas shaft on which an awning canvas is adapted to be wound;   at least one shaft end piece that is inserted into the canvas shaft in an axial end region thereof, the shaft end piece being connected to the canvas shaft in a force-fitting manner;   a pressing part, which is inserted into the canvas shaft, being movable relative to the shaft end piece and/or to the canvas shaft in an axial direction and/or in a circumferential direction of the canvas shaft between a clamping position and a release position, and, in the clamping position, exerts a radial pressing force on the shaft end piece and clamps the shaft end piece against an inner wall of the canvas shaft; and   at least one clamping bar being guided through the pressing part and the shaft end piece, and via which the pressing part is movable from the release position into the clamping position, the clamping bar, in a bearing region arranged outside the canvas shaft, has a bearing pin via which the canvas shaft is adapted to be rotatably mounted in a bearing.   
     
     
         2 . The canvas shaft holder according to  claim 1 , wherein the clamping bar extends in the axial longitudinal direction of the canvas shaft. 
     
     
         3 . The canvas shaft holder according to  claim 1 , wherein the clamping bar and the bearing pin are designed as a one-piece component. 
     
     
         4 . The canvas shaft holder according to  claim 1 , wherein the clamping bar has a threaded portion, with which a clamping element is adapted to be brought into engagement, and wherein the clamping bar is movable in the axial direction of the canvas shaft via the clamping element. 
     
     
         5 . The canvas shaft holder according to  claim 4 , wherein the shaft end piece, on a side facing away from the canvas shaft, has a locking, via which the clamping element is adapted to be locked in the clamping position of the pressing part. 
     
     
         6 . The canvas shaft holder according to  claim 1 , wherein the clamping bar has a rotation preventor, via which the clamping bar is mounted in a rotationally fixed manner relative to the pressing part. 
     
     
         7 . The canvas shaft holder according to  claim 1 , wherein the pressing part, in the axial direction of the canvas shaft, has at least in part a conical pressing surface, via which the shaft end piece is adapted to be radially splayed. 
     
     
         8 . The canvas shaft holder according to  claim 1 , wherein the shaft end piece, on a shaft side facing toward an interior of the canvas shaft, has a pressing recess into which the pressing part is adapted to be inserted. 
     
     
         9 . The canvas shaft holder according to  claim 1 , wherein the shaft end piece has several splayable ribs arranged spaced apart around a shaft circumference, which in the clamping position are radially splayed via the pressing force. 
     
     
         10 . The canvas shaft holder according to  claim 1 , wherein the shaft end piece has at least one guide, via which the pressing part in the clamping position is mounted in a rotationally fixed manner relative to the shaft end piece and which guides the pressing part during the axial movement thereof.
