Tool holding appliance for persons with limited use of hands
First Claim
1. In a tool holding appliance, a tool holding socket, a rotatable body that is a tool holding socket support, and a fixed body having an axis on which said rotatable body is rotatable, said fixed body being provided with slots to receive an attachment strap for attaching said body to the limb of a user, the novelty comprising:
- the fixed body comprising a circumferential outer rim about the rotatable body having an axis coaxial with the axis of the fixed body, the rotatable body being provided with an outwardly opening circumferential O-ring groove and said fixed body being provided with an inwardly opening O-ring groove complementary to said outwardly opening O-ring groove whereby an O-ring may be placed in one of said grooves and the rotatable body and the rim may be snapped together with the O-ring snapping into said complementary grooves to retain the parts assembled, the O-ring being of a size to control the frictional engagement between the parts by engagement with said grooves whereby to hold the rotatable body in a desired position unless a force greater than the frictional force between the O-ring and the grooves is exerted by a user.

Abstract
A tool holding device for persons with limited hand mobility has complementary tool handles and socket of cylindrical or conical form. The socket is integral with a rotatable part and may have an upper open section above the socket diameter permitting tools to be snapped into rotatable relationship with the socket. The rotatable base for the socket is surrounded by an annular fixed housing, and housing and socket base have complementary facing O-ring grooves above which the housing has a locating flange turned inward over the rotatable socket base. The O-ring locates the parts and provides frictional holding force while allowing snap-out snap-in disassembly for cleaning. A strap through the fixed rim retains the parts in assembly and has hook and loop or other easily fastened fasteners for securing the unit to the hand or other limb of the user.
