Abstract
Abstract An adjustable table is provided for use with a hospital bed and which allows a person reclining in the bed to easily change the angle of inclination of the table surface. The planar member is rotatably connected at one end to and extended horizontally outward from a vertical support member by means of frictionally engaged gripping elements. Lifting up on the free end of the planar member disengages the gripping elements whereby the planar member can thereafter be freely tilted or rotated about its longitudinal axis to a selected angle of inclination. Lowering the free end of the planar member to its original position re-engages the gripping elements to fix the planar member at the selected angle of inclination.

Claim 1
Independent Claim
97 words
An adjustable table having a base and an upright support member mounted on said base, comprising: a horizontal support member rotatably connected at one extremity to said upright support member and extending outwardly therefrom, a first table portion secured along one surface to said horizontal support member, a first substantially vertically disposed frictional element secured to said upright support member, a second substantially vertically disposed frictional element secured to said first table portion and positioned to engage said first frictional element, and means cooperating with said horizontal support member for disengaging said first and second frictional elements.
Claim 2
Dependent Claim
97 words
An adjustable table having a base and an upright support member mounted on said base, comprising: a horizontal support member rotatably connected at one extremity to said upright support member and extending outwardly therefrom, a first table portion secured along one surface to said horizontal support member, a first substantially vertically disposed frictional element secured to said upright support member, a second substantially vertically disposed frictional element secured to said first table portion and positioned to engage said first frictional element, and means cooperating with said horizontal support member for disengaging said first and second frictional elements.
Claim 3
Dependent Claim
17 words
The table described in claim 1, wherein said first and second frictional elements are substantially arcuately shaped.
Claim 4
Dependent Claim
24 words
