Abstract
The apparatus is attachable and detachable to walkers via rotating spring clips attached to the rails or legs of walkers. It is stable, attached at three points, yet variable in height and angle of surface by use of the telescopic brace, rotating clips and sliding brace attached to the tray angle by wing nuts and bolts. It is usable and storable and out of the walker user's way via the rotating attachment clips and telescopic brace. It does not rust not corrode and is cleanable with soap and water. The sliding of the brace horizontally in the angle, the telescopic variable height and tray angle, the angles of bends of the brace ends, and fully rotating attachment clips allow the apparatus to be assembled, attached and detached to multiple designs of walkers. The variable angle of the tray surface provides a writing surface while the apparatus is attached. The tray is countersunk and usable while attached for carrying items. Without the use of tools, the apparatus is assembled, attached or detached to walkers. The entire apparatus, when attached, fits inside the exterior side-to-side dimensions of the walker and does not interfere with the user nor use of the walker during movement …
