Height adjustable working table

Abstract

The invention relates to a height adjustable working table ( 1 ) with two guide tracks ( 3 ) for mounting a working surface ( 2 ) which may adjusted for height by means of a drive motor ( 15 ) with cable pulleys and draw cables ( 13 ).

1 . A height-adjustable working table with at least two guide rails ( 3 ) for receiving a worktop ( 2 ), which is adjustable in its working height by means of a drive motor with at least one cable drum and pull cables, wherein each guide rail ( 3 ) is formed by a profile and the worktop ( 2 ) is mounted displaceably on the guide rails in such a way that the downward movement of the worktop takes place by virtue of its own weight, the drive motor ( 15 ) with the cable drum ( 14 ) being arranged in the region of the worktop ( 2 ), and the guide rails ( 3 ) having means ( 16 ) with which in each case one end of the pull cables ( 13 ) can preferably be attached at the upper ends of the guide rods.  
   
   
       2 . The working table as claimed in  claim 1 , wherein the worktop ( 2 ) has a means ( 11 , 12 ) which interacts with the guide rails ( 3 ) on the inner and/or outer cross section.  
   
   
       3 . The working table as claimed in  claim 1 , wherein the guide rail ( 3 ) is designed essentially, as a rectangular tube.  
   
   
       4 . The working table as claimed in  claim 2 , wherein the means is a front and a rear roller ( 11 ,  12 ).  
   
   
       5 . The working table as claimed in  claim 4 , wherein the front roller ( 12 ) and the rear roller ( 11 ) each bear against the outer cross section of the guide rail ( 3 ), at the bottom and at the top respectively.  
   
   
       6 . The working table as claimed in  claim 4 , wherein the front roller ( 12 ) and the rear roller ( 11 ) each bear against the inner cross section of the guide rail ( 3 ), at the top and at the bottom respectively.  
   
   
       7 . The working table as claimed in  claim 4 , wherein the rollers ( 11 ,  12 ) are formed by ball bearings.
