ABSTRACT:
The present invention relates to a tray table for invalid chairs operable in two modes, and methods for making and operating the tray table. Runners on the tray slide into brackets mounted to the arms of the chair, thus maintaining the tray in position in front of the patient. A detent mounted to at least one bracket is capable of engaging a hole on at least one runner. In one mode, the detent engages the hole in the tray table, locking the tray table in position on the chair. In a second mode, a sliding block is displaced under the knob of the detent. The detent is thereby maintained in a retained condition such that the runner may freely slide in and out of the bracket.
