Adjustable tool mount apparatus and specialized tool handle thereof

A quick connect tool mount apparatus for adjustably and releasably securing the rear end of a handgrip handle of painting and other hand tools having the tool-mounting hand grip handle configured for supporting a hand tool for intended, primary operation held in a single hand of a user onto a threaded tool mount shaft of an extension pole member for orienting the hand tool for use of the normally hand-held hand tool thereon at extended reach from a user, said quick connect tool mount apparatus comprising:

• a) a tool handle end member associated with the rear terminal end of a hand tool handle, said end member having a substantially cylindrical external body portion configured with a predetermined, substantially cylindrical external surface diameter and a plurality of equally circumferentially spaced-apart studs on and projecting axially rearwardly from the rear terminal end of the end member body,
• b) an elongated, end member-receiving coupler body member configured for mounting onto the threaded tool mount shaft of an extension pole member, said coupler body member having opposite longitudinal end portions, one said longitudinal end portion providing a substantially hollow cavity having an internal diameter configured for axial sliding reception of said cylindrical body portion of the tool handle end member inserted thereinto, the cavity terminating in an inner, rear end wall having a plurality of equally circumferentially spaced-apart bores therein arranged to matingly correspond with and receive said studs projecting axially from said rear terminal end of said cylindrical body portion of the tool handle end member fully inserted into the cavity of said one end of the coupler body member to prevent relative rotation of the fully inserted end member and coupler body member, and
• c) lock means for releasably engaging the cylindrical body portion of the tool handle end member fully inserted into said hollow cavity and releasably securing the end member therein with said axially projecting studs matingly received in said corresponding bores in the rear end wall of the cavity of the coupler body member and with the tool handle projecting axially from the coupler body member, whereby
• d) with the coupler body member mounted on the threaded tool mount shaft of an extension pole member, the tool handle end member on the terminal end of the tool handle may be inserted partially into the cavity of the coupler body member and the tool handle rotated to orient the hand tool as desired for use on the extension pole member and to bring the plurality of corresponding studs and bores into axial alignment for mating reception therebetween as the tool handle end member is inserted fully into said cavity whereupon the locking means engages the cylindrical body portion of the end member to releasably secure the hand tool handle in desired orientation connected to the coupler body member supported on the threaded tool mount shaft of the extension pole member.
