ABSTRACT:
An improvement to a gripping device for handicapped persons provides a three-point lateral restraint. The structure for accomplishing this restraint includes a thumb support element, a wrist brace element and an arm support element. These respective elements may be quickly mounted on either side of the device, thereby enabling the device to be used by either right-handed or left-handed persons. A lanyard including a noose is also provided to faciliate convenient manipulation of the gripping device by the free hand of the user. A toggle mechanism includes an over-the-center spring for controlling a pair of gripping tongs.
