<p>A system for rotating a paintbrush that connects handle (31), which may also be connected to an extension pole, to a paintbrush (10) comprises a rotary connection device (36) or silicone tube sections (80, 81) including a first member (56) having an internal cylindrical surface (57) and a second member (33) located within and substantially coaxial with the member (56) and having an external cylindrical surface. One member is attached to the handle (31), and the other to the paintbrush. If the bristles of the brush (10) are place in a painting position against a surface with the axis of the brush extending substantially perpendicular to the surface and the handle (31) is moved with a circular motion substantially coinciding with the axis of the brush, the cylindrical surfaces of the two members will interact and cause the brush to rotate about its axis.</p> |
