Height-Adjustable Pedestal

Abstract

The invention relates to a height-adjustable pedestal comprising a height adjustable pedestal platform, a spring device that provides a spring force according to a corresponding spring characteristic, and a lever mechanism that is interconnected between the spring device and the pedestal platform in such a way that the spring force is transferred by the lever mechanism to the pedestal platform in the form of a lifting force that counteracts the weight force of the pedestal platform, in order to facilitate the height-adjustment of the pedestal platform, wherein the lever mechanism is configured such that it at least partially compensates for a variation of the spring force that occurs according to the spring characteristics.

1 . A height-adjustable pedestal comprising:
 a height-adjustable pedestal platform,   a spring device that provides a spring force according to a corresponding spring characteristic, and   a lever mechanism that is interconnected between the spring device and the pedestal platform in such a way that the spring force is transferred by the lever mechanism to the pedestal platform in a manner so as to provide a lifting force that counteracts the weight force of the pedestal platform in order to facilitate the height-adjustment of the pedestal platform, wherein the lever mechanism is configured such that it at least partially compensates for a variation of the spring force that occurs according to the spring characteristic.   
     
     
         2 . The pedestal according to  claim 1 , wherein the lever mechanism comprises
 a cam disc that defines a leverage ratio variation, and   a cable that is guided over the cam disc, and   wherein the spring force is transferred to the pedestal platform by means of the cable.   
     
     
         3 . The pedestal according to  claim 2 , wherein the cam disc is a cone-shaped body with a curved line formed thereon, wherein the curved line extends along the cone-shaped body in a helically wound spiral manner. 
     
     
         4 . The pedestal according to  claim 2 , wherein the spring device comprises a mechanical spring. 
     
     
         5 . The pedestal according to  claim 4 , wherein the mechanical spring is a torsion spring. 
     
     
         6 . The pedestal according to  claim 4 , wherein the mechanical spring is arranged coaxially with a rotation shaft of the cam disc. 
     
     
         7 . The pedestal according to  claim 6 , wherein the mechanical spring is a torsion spring. 
     
     
         8 . The pedestal according to  claim 7 , wherein one end of the torsion spring is non-rotatably coupled to the cam disc so as to co-rotate with the cam disc. 
     
     
         9 . The pedestal according to  claim 4 , wherein the mechanical spring is a coil spring, which is arranged with its longitudinal direction being aligned vertically. 
     
     
         10 . The pedestal according to  claim 4 , wherein the mechanical spring is a coil spring, which is arranged with its longitudinal direction being aligned horizontally. 
     
     
         11 . The pedestal according to  claim 1 , wherein the spring device comprises a mechanical spring. 
     
     
         12 . The pedestal according to  claim 11 , wherein the mechanical spring is a torsion spring. 
     
     
         13 . The pedestal according to  claim 11 , wherein the mechanical spring is a coil spring, which is arranged with its longitudinal direction being aligned vertically. 
     
     
         14 . The pedestal according to  claim 11 , wherein the mechanical spring is a coil spring, which is arranged with its longitudinal direction being aligned horizontally. 
     
     
         15 . The pedestal according to  claim 1 , wherein the spring device and the lever mechanism are arranged to be stationary. 
     
     
         16 . The pedestal according to  claim 1 , wherein the spring device and the lever mechanism are arranged on the pedestal platform to be vertically movable therewith. 
     
     
         17 . The pedestal according to  claim 1 , wherein the pedestal comprises two spring devices. 
     
     
         18 . The pedestal according to  claim 17 , wherein each of the two spring devices comprises a coil spring. 
     
     
         19 . The pedestal according to  claim 18 , wherein each of the coil springs is arranged with its longitudinal axis being aligned horizontally, and wherein the two coil springs are arranged one above the other. 
     
     
         20 . The pedestal according to  claim 1 , wherein the pedestal comprises a guiding device, and
 wherein the pedestal platform is movable along the guiding device while being guided along the guiding device in a vertical direction defined by the guiding device.
