Abstract:
1. In combination: a sanding block having at least one sanding surface with a generally round perimeter; a ball; a socket coupled to said ball and operative therewith as a first pivoting joint, said socket further firmly coupled to said sanding block; a handle coupling operative to couple with an elongated pole for manipulation by a person; a neck having a transverse cross-section smaller than a diameter of said ball and smaller than a transverse cross-section of said handle coupling, said neck rigidly coupling said handle coupling to said ball; and castellations within said socket, each of size comparable to said neck and suitable to engage said neck at a limit of angular position with respect to said socket, said neck having a full angular range of motion extending primarily outside of said castellations, said castellations permitting more degrees of freedom between said socket and said handle coupling, while simultaneously permitting said neck to be locked relative to said socket by engaging said neck with at least one of said castellations at said limit of angular position.
