ABSTRACT:
A pivoting tray is provided for a walker. A pair of link arms disposed on each side of the tray provide for ease of movement between a first, operative position disposed between side frame assemblies of the walker, to a second, storage position generally vertically oriented in front of the walker. The mounting brackets are adapted for use with either a single actuator or dual release style of walker. Moreover, the mounting bracket is symmetrical for use on both the right-hand and left-hand sides of the walker, thereby reducing manufacturing costs and inventory.
