Mobile workstation

Abstract

A mobile workstation comprises a generally horizontal work surface and a plurality of support structures coupled to the work station to support the work surface above a floor. The mobile workstation is configured to permit the workstation to be moved from one work area to another.

1 . A mobile workstation comprising 
 a work table including a top surface, a bottom surface, and legs extending downwardly from the bottom surface and adapted to rest on an underlying surface,    a truck including a base coupled to the work table, wheels coupled to the base, and an axle extending between the wheels, and    lift means for lifting the wheels away from the underlying surface to inhibit movement of the work table and truck relative to the underlying surface in response to tipping movement of the work table and truck relative to the underlying surface.    
   
   
       2 . The mobile workstation of  claim 1 , wherein the lift means includes a lifting wedge coupled to the base.  
   
   
       3 . The mobile workstation of  claim 2 , wherein the lifting wedge includes a top surface, a downwardly facing angled surface arranged to intersect the top surface to form an acute included angle therebetween, and a vertical surface arranged to intersect the downwardly-facing angled surface to define a leading edge and further arranged to extend upwardly to intersect the top surface, wherein the top surface, downwardly facing angled surface, and vertical surface cooperate to form a right triangle.  
   
   
       4 . The mobile workstation of  claim 3 , wherein the base includes a downwardly facing angled portion arranged to form a co-planar surface with the downwardly facing angled surface of the lifting wedge.  
   
   
       5 . The mobile workstation of  claim 3 , wherein a lowest point of each wheel cooperates with the leading edge to define a gap therebetween when the base is substantially perpendicular to the underlying surface.  
   
   
       6 . The mobile workstation of  claim 3 , wherein the leading edge is positioned to lie between the work table and the lowest point of each wheel when the truck is pivoted to cause the legs to move away from and the wheels to engage the underlying surface.  
   
   
       7 . The mobile workstation of  claim 3 , wherein the lifting wedge and the base cooperate to define a table support and the table support is monolithic.  
   
   
       8 . The mobile workstation of  claim 1 , wherein the base includes a bottom surface having a generally horizontal portion and a downwardly facing angled portion forming an obtuse included angle therebetween.  
   
   
       9 . A mobile workstation comprising 
 a work table including a top surface, a bottom surface, and legs extending downwardly from the bottom surface and adapted to rest on an underlying surface,    a truck including a base coupled to the work table, wheels coupled to the base, and an axle coupled to the base and configured to support the wheels for rotation about an axis of rotation, and    a lifting wedge coupled to the base and configured to include a horizontal top surface, a vertical side surface, a downwardly facing angled surface adjacent the vertical side surface, and a leading edge formed by the intersection of the vertical side surface and the downwardly facing angled surface.    
   
   
       10 . The mobile workstation of  claim 9 , wherein the downwardly facing angled surface is arranged to intersect the top surface to define an acute included angle therebetween.  
   
   
       11 . The mobile workstation of  claim 10 , wherein a lowest point of each wheel cooperates with the leading edge to define a gap therebetween when the base is substantially perpendicular to the underlying surface.  
   
   
       12 . The mobile workstation of  claim 10 , wherein the leading edge is positioned to lie between the work table and the lowest point of each wheel when the truck is pivoted to cause the legs to move away from and the wheels to engage the underlying surface.  
   
   
       13 . The mobile workstation of  claim 12 , wherein the base includes a bottom surface having a generally horizontal portion and a downwardly facing angled portion arranged to define an obtuse included angle.  
   
   
       14 . The mobile workstation of  claim 9 , wherein the lifting wedge and the base cooperate to define a table support and the table support is monolithic.  
   
   
       15 . The mobile workstation of  claim 9 , wherein the base includes a downwardly facing angled portion arranged to form a co-planar surface with the downwardly facing angled surface of the lifting wedge.  
   
   
       16 . The mobile workstation of  claim 15 , wherein the co-planar surface cooperates with the underlying surface to define a first acute included angle when a longitudinal axis of the base is in a substantially perpendicular relationship relative to the underlying surface.  
   
   
       17 . The mobile workstation of  claim 16 , wherein a second acute included angle smaller than the first acute included angle is defined by the co-planar surface and the underlying surface when the base is pivoted such that the wheels engage the underlying surface.  
   
   
       18 . A mobile workstation comprising 
 a work table including a top surface, a bottom surface, and legs extending downwardly from the bottom surface and adapted to rest on an underlying surface,    a truck including a base coupled to the work table, wheels coupled to the base, and an axle extending between the wheels, and    a lifting wedge depending from the base and being formed to include a leading edge configured to engage an underlying surface when the truck is in a substantially perpendicular relationship to the underlying surface to move the wheels away from the underlying surface.    
   
   
       19 . The mobile workstation of  claim 18 , wherein the lifting wedge includes a top surface coupled to the base, a downwardly facing angled surface arranged to intersect the top surface to define an acute included angle, and a vertical surface arranged to extend between the top surface and the downwardly facing angled surface.  
   
   
       20 . The mobile workstation of  claim 19 , wherein the downwardly facing angled portion is arranged to form a co-planar surface with the downwardly facing angled surface of the lifting wedge.
