  • Patent number: 5392802
    Abstract: A fold-down detachable utility tray for invalid walkers is disclosed, including a generally rectangular tray frame in combination with a pair of locking, fold-down arms each having spring clips for securement to the upright members of an invalid walker. In one preferred embodiment, the center of gravity of the tray is located over the pivot point of the locking arms, so that the weight of objects placed on the tray causes the arms to lock more tightly, promoting stability of the tray. The locking arms each include an elongated angle bracket provided with a pivot. An actuator arm has a first end movably connected to the pivot and a second end slidingly engaged in a slot in the tray frame. One end of the slot is provided with a upwardly extending locking notch to hold the arm in the extended position.
