Abstract
Abstract This disclosure is of a portable supporting construction primarily devised for use on or in connection with beds or wheel chairs, which construction includes a single support member having a mounting device at each end, which devices include means to facilitate rotative movement of the support member into various positions, in which positions the member may be locked, the member having adjustable means thereon which will engage a tray or the like, whereby the tray may be pivoted with the member and removed when desired, the tray or the like thus being angularly positioned with respect to the area over which it is supported when in use.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
82 words
In portable construction of the class described, in combination, a support member, a tray-like means carried thereby, a mounting device at each end of the member, said devices including means providing for rotative movement of the member, instrumentalities to lock said member in various rotative positions and means connecting the tray-like means to said member, said connecting means being adjustable transversely along the support member and interengaged therewith for rotation thereby, whereby the means will be rotated simultaneously with the support member.
Claim 2
Dependent Claim
82 words
In portable construction of the class described, in combination, a support member, a tray-like means carried thereby, a mounting device at each end of the member, said devices including means providing for rotative movement of the member, instrumentalities to lock said member in various rotative positions and means connecting the tray-like means to said member, said connecting means being adjustable transversely along the support member and interengaged therewith for rotation thereby, whereby the means will be rotated simultaneously with the support member.
Claim 3
Dependent Claim
61 words
Construction as claimed in claim 1, wherein the support member is a rectangular bar, and the instrumentalities to lock the member comprise a socket in one of the devices to receive an end of said member and to lock the same in various rotative positions around said bar, means being provided to selectively maintain said member in one of said positions.
Claim 4
Dependent Claim
