Abstract:
An extended reciprocating tool, intended to drive any tool head adapted to perform any type of abrasive action including but not restricted to sanding, scraping, and scrubbing in a reciprocating stroke displacement, said extended reciprocating tool comprising:a graspable main body containing an electric motor, a power supply, a graspable sleeve, a rigid longitudinal extension, frictional suspension means, and a coupling;said graspable sleeve comprising a rigid longitudinal structure possessing a longitudinal interior through which said rigid longitudinal extension extends longitudinally;said rigid longitudinal extension possessing a rear end mechanically linked to said electric motor such that operation of said electric motor exerts a reciprocating drive upon said rear end of said rigid longitudinal extension;said frictional suspension means frictionally suspending said rigid longitudinal extension within said graspable sleeve such that reciprocal longitudinal displacement of said rigid longitudinal extension with respect to said graspable sleeve without direct contact between said rigid longitudinal extension and said graspable sleeve is facilitated;said rigid longitudinal extension possessing a front end terminating in said coupling, said coupling providing mechanical attachment of an abrasive tool head to said front end of said rigid longitudinal extension;operation of said electric motor within said graspable main body thereby causing reciprocation of said rigid longitudinal extension with respect to said graspable sleeve which may be grasped by one hand and held immobile with respect to the reciprocating rigid longitudinal extension;whereby mechanical attachment of a selected abrasive tool head upon said front end of said rigid longitudinal extension with said coupling, grasping of said main body with one hand, grasping of said sleeve with another hand, and operation of said electric motor effects powered reciprocal displacement of said tool head in a manner which is readily guided in the performance of a selected abrasive task at a remove from said main body.
