Abstract
A pair of paint rollers are respectively rotatably mounted to a pair of parallel, spaced apart axle members that form a part of a rigid frame. A rigid clip rod at the center of the frame is releasably engaged by a clip member that is pivotally secured to a handle-receiving socket member at the leading end of an elongate handle which is held by a painter when paint is applied to a preselected surface. The pivotal attachment allows pivotal movement between the clip member and hence the frame and the longitudinal axis of the elongate handle in a first plane. The clip rod is cylindrical and is captured by the clip member when the clip member is in a position of repose, but the cylindrical surface allows the frame member to pivot with respect to the clip member and hence the elongate handle in a second plane that is normal to the first plane. A lock member is slideably mounted on the leading end of the socket member. It does not interfere with the pivotal movement in the first plane when in a retracted position, but it disable the pivotal movement in the first plane when in an extended position.
