Mobile stand

Abstract

The present invention relates to a mobile stand in particular shading umbrellas, comprising a foot ( 1 ) which may be raised/lowered relative to the ground ( 4 ), furthermore a roller fixture ( 2 ) having at least three rollers and a lifting device connecting the foot ( 1 ) to the roller fixture ( 2 ) in a manner that the foot ( 1 ) is displaceable relative to the roller fixture ( 2 ). In order to optimize comfort of use and simultaneously to minimize danger of injury, said stand's design furthermore provides that the roller fixture ( 2 ) shall be configured above the foot ( 1 ). FIG. 1 a illustrates the abstract.

1 . A mobile stand, in particular for a shading umbrella, comprising: 
 a stand foot, hereafter foot, which can be raised/lowered relative to the ground,    a roller fixture which is fitted with at least three rollers and which is configured above the foot,    a lifting device connecting the foot in such manner to the roller fixture that the foot is displaceable relative to the roller fixture,    the weight of the foot being larger than that of the roller fixture in a manner that the positional stability of the stand is preponderantly assured by the weight of the foot.    
   
   
       2 . Stand as claimed in  claim 1 , characterized in that the roller fixture is intrinsically rigid.  
   
   
       3 . Stand as claimed in  claim 1 , characterized in that the roller fixture comprises a plate.  
   
   
       4 . Stand as claimed in  claim 1 , characterized in that the roller fixture is a rack, in particular composed of rods, bars or shapes such as U channels, T-bars and the like.  
   
   
       5 . Stand as claimed in  claim 1 , characterized in that the roller fixture constitutes a plane support surface parallel to the ground.  
   
   
       6 . Stand as claimed in  claim 1 , characterized in that the roller fixture comprises a cover element in particular made of plastic.  
   
   
       7 . Stand as claimed in  claim 6 , characterized in that the cover element comprises a downward pointing collar at its external periphery in a manner that the collar laterally encloses the foot and the roller fixture.  
   
   
       8 . Stand as claimed in  claim 1 , characterized in that the roller fixture comprises a downward-pointing collar at its outer periphery in a manner that the collar laterally encloses the foot.  
   
   
       9 . Stand as claimed in  claim 7 , characterized in that the collar comprises a preferably resilient soil-repelling element, in particular made of rubber or bristles, that runs along its lower edge.  
   
   
       10 . Stand as claimed in  claim 1 , characterized in that the foot comprises a plate.  
   
   
       11 . Stand as claimed in  claim 1 , characterized in that the foot comprises a rack in particular consisting of rods, bars or shapes such as U-channels, T-bars and the like.  
   
   
       12 . Stand as claimed in  claim 11 , characterized in that the rack is configured in a manner that several weight segments may be received by it.  
   
   
       13 . Stand as claimed in  claim 1 , characterized in that the foot is fitted at its underside with paws in particular made of plastic.  
   
   
       14 . Stand as claimed in  claim 1 , characterized in that the foot comprises at least at its underside a coating in particular made of plastic.  
   
   
       15 . Stand as claimed in  claim 1 , characterized in that the foot is configured within the zone enclosed by the rollers.  
   
   
       16 . Stand as claimed in  claim 1 , characterized in that the foot laterally extends beyond the zone enclosed by the rollers, clearances being optionally provided in the region of the rollers.  
   
   
       17 . Stand as claimed in  claim 1 , characterized in that the foot is made of a metal, in particular steel or lead.  
   
   
       18 . Stand as claimed in  claim 1 , characterized in that the weight of the foot is larger than that of the roller fixture.  
   
   
       19 . Stand as claimed in  claim 1 , characterized in that the lifting device is configured above the roller fixture.  
   
   
       20 . Stand as claimed in  claim 1 , characterized in that, in order to displace the foot relative to the roller fixture, the lifting device comprises one or more of the following means: a lever, a rocker element, a cable or chain drive, a gear unit.  
   
   
       21 . Stand as claimed in  claim 1 , characterized in that the lifting device comprises an adjustment motor, in particular an electric motor which is preferably remote-controlled.  
   
   
       22 . Stand as claimed in  claim 1 , characterized in that a pushrod is connected in preferably detachable manner to the stand.  
   
   
       23 . Stand as claimed in  claim 22 , characterized in that the pushrod is a component of the lifting device.
