A hand tool according to the present invention comprises in combination, a workpiece assembly and a handle assembly adapted for quick release coupling to one another to provide a manually supported tool having rapidly interchangeable workpieces. The workpiece assembly includes a work head adapted to function as a painting or decorating tool or the like and a support member on the head. The support member has a section of its length disposed rearwardly from the head which extends in a tortuous path to form a first coupler element. The handle assembly comprises an elongated manually engageable handle and a quick release clamp. The quick release clamp comprises first and second jaws which have a clamping face formed with a channel-shaped clamping recess which extends along a tortuous path corresponding to that followed by the coupler element whereby the coupler element may be seated in the clamping recess in a close fitting relationship. The tortuous path in the clamp and on the support member are arranged in a configuration to prevent relative movement between the head and the handle in use.

In combination, a paint or a decorating workpiece assembly and a handle assembly adapted for quick release coupling to one another to provide a manually supported tool having a rapidly interchangeable workpiece, said workpiece assembly comprising; (a) a work head adapted to function as a painting or decorating tool, (b) a support member mounted on said work head, said support member having a section of its length disposed rearwardly from said work head which extends in a tortuous path to form a first coupler element, said handle assembly comprising, (i) an elongated manually engageable handle having an inner end and an outer end, (ii) a quick release clamp assembly comprising first and second jaw members, said first jaw member having a first face which extends outwardly from the outer end of said handle toward said work head in a first plane, a channel-shaped recess formed in said first face of said first jaw member and extending to a substantial depth below said first plane, said recess having a mounting passage opening longitudinally thereof in said first plane, said recess extending along said first jaw in a tortuous path, the configuration of which is such that the walls of the recess restrict relative movement between said first coupler element and said first jaw to movement into and out of said recess through said mounting passage in a first direction substantially perpendicular to said first plane, at least one end of said recess opening outwardly from said first jaw member at one edge of said first jaw member through which said support member extends to communicate between said first coupler element and said work head, said second jaw member having a second clamping face, said second jaw member being adapted to cooperate with said first jaw member for movement relative to said second jaw member between the clamping position in which said second clamping face overlies and closes said mounting passage of said channel-shaped recess to retain said first coupler element against movement in said first direction and a second position in which said clamping face is spaced from said second jaw to permit mounting and removal of said coupler element through said mounting passage, (iii) means for securing said jaws with respect to one another in said clamping position comprising a U-shaped body having first and second oppositely disposed legs spaced from one another by a clamping channel, said first leg being adapted to pivot on the outer edge of one of said jaws from a first position in which the second leg overlies and engages the outer end of the other jaw and secures the outer end of said jaws within said clamping channel to retain said jaws in said clamping position, said body being pivotable about its pivotal connection to move said second leg away from said first position to a position spaced from said other jaw to release said jaws for movement to said release position.
