Claim Text:
1. A removable tray device for use with a chair comprising: a tray component comprising a top surface, a bottom surface, a front edge, and a back edge; and a swivel component secured to a left front leg of the chair for removably securing the tray component to the left front leg and for swiveling horizontally relative to a plane of the tray component; and a pinned hinge secured to the swivel component for allowing the tray component to rotate vertically up for use or down into a storage position relative to a leg of the chair; and wherein the pinned hinge comprises a pin, a hinge joint, and a locking collar which acts to lock or release the pinned hinge; and wherein a snap ring holds a spring onto the locking collar to allow the collar to move up and down to cover or uncover the hinge joint; and wherein the locking collar is secured to the tray component via a bracket such that when the locking collar is pushed in, the tray component rotates up or down, and when the locking collar is released and the spring pushes against the collar, the collar moves over the hinge joint, locking the tray component in place so it cannot rotate up or down; and wherein the pinned hinge allows the tray component to rotate vertically out in front of the chair relative to the leg of the chair and the swivel component allows the tray component to swivel horizontally in front of the chair for use relative to the plane of the tray component; and a pair of support arms secured to the bottom surface of the tray component, wherein the pair of support arms fold up and store under the tray component when not in use, and are folded down and secured to legs of the chair via a raised bolt when in use.
