Portable adjustable table extension for use by the physically impaired

Abstract

A portable, detachable desk or table extension is disclosed for use by a person in a wheelchair that may be vertically and angularly adjusted to an optimum height and position for use. The extension has a portable work surface or platform that extends out, away from, and above the surface of the desk or table to which it is attached, so that a user in a wheel chair may pull up to and under it and not be blocked or hindered by the table or desk underneath. The elevation as well as the angle of tilt of the platform may be adjusted for optimum positioning so that the user in a wheelchair may pull up close to and under it. The extension clamps to the table via a pair of vertical supports.

1 - 2 . (canceled)  
   
   
       3 . A portable work surface for attachment to a stationary structure, the stationary structure having a stationary work surface, comprising: 
 a platform having a planar work surface;    a pair of spaced apart support members coupled to the platform;    wherein said support members are configured to support the platform at an elevation above the stationary work surface;    wherein said support members are configured to abut at least partially against a side edge of the stationary structure;    at least one bracing member coupled to the support elements;    wherein the bracing member is configured to contact the stationary work surface; and    at least one clamping member coupled to the support elements;    wherein the clamping member is configured to contact a lower surface of the stationary structure to releasably secure the support members to the stationary structure.    
   
   
       4 . A portable work surface as recited in  claim 3 , wherein the platform is coupled to the support members so that the platform is capable of translating with respect to the support members to alter the elevation of the platform with respect to the stationary work surface.  
   
   
       5 . A portable work surface as recited in  claim 3 , wherein the platform is rotatably coupled to the support members so that the platform is capable of rotating with respect to the support elements to alter the angle of the platform with respect to the stationary work surface.
