Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 287 words
In combination with a chair structure comprising a pair of similar tubular side frames joined by seat and backrest members each of said frames including front and rear leg portions and an armrest; a tubular frame member affixed to the outside of one of said frames; a tray; a generally U-shaped supporting member for said tray, said supporting member having two spaced apart substantially parallel legs, one of said legs being pivotally secured to the undersurface of said trAy, the other of said legs being hollow and telescopingly received by said tubular frame member, said legs being spaced apart a distance substantially the same as the distance between said tubular frame member and the upper surface of the armrest on the one of said frames to which said tubular member is attached; and bracket means for selectively fastening the undersurface of the opposite edge of said tray in the position of use to the armrest of the other of said frames and in the stored position to the armrest portion of the one of said frames to which said tubular member is attached, the improvement which comprises: means interconnecting said tubular member and the other of said legs to permit relative rotational movement therebetween and limited relative longitudinal movement and prevent disassociation therebetween to militate against the removal of said tray from the chair including a rod having one end affixed to said tubular frame member, said other leg having a reduced opening in the end thereof, the other end of said rod fitted through the opening in said leg, and stop means on said other end of said rod providing a limit to the relative longitudinal movement between said tubular frame member and said other leg.
