1. A paint brush system (10) comprising:
a lower component (22) having a cylindrical handle (14) adjacent to the lower end of the system, the cylindrical handle having a threaded aperture (24) extending upwardly into the cylindrical handle from the lower end of the system, the threaded aperture adapted to threadedly receive a threaded end of a conventional pole for painting at elevated locations, the lower component having a first cylindrical disk (28) with a first exterior surface (30) and a first interior surface (32), the lower component having a first cylindrical coupler (34) joining the cylindrical handle and the first cylindrical disk, the cylindrical handle having a first diameter and a first central axis, the first cylindrical disk having a second diameter and a second central axis, the first cylindrical coupler having a third diameter and a third central axis, the third diameter being less than the first diameter, the third central axis being parallel with and laterally offset from the first central axis, the second diameter being equal to the first diameter, the second central axis being at a right angle with respect to both the first central axis and the third central axis; an upper component (38) having a cylindrical base (40) and with bristles (18) adjacent to the upper end (16) of the system, the bristles being in a bristle plane, the upper component having a second cylindrical disk (42) with a second exterior surface 44 and a second interior surface (46), the upper component having a second cylindrical coupler (48) joining the bristles and the second cylindrical disk, the cylindrical base having a fourth diameter and a fourth central axis, the second cylindrical disk having a fifth diameter and a fifth central axis, the second cylindrical coupler having a sixth diameter and a sixth central axis, the sixth diameter being less than the fourth diameter, the sixth central axis being parallel with and laterally offset from the fourth central axis, the fifth diameter being less than the fourth diameter, the fifth central axis being at a right angle with respect to both the fourth central axis and the sixth central axis; and an adjustment assembly (52) intermediate the upper component and the lower component, the adjustment assembly including triangular recesses (58) projecting axially outwardly from the first interior surface of the first cylindrical disk, an annular first surface (60) in a planar configuration radially exterior of the triangular recesses, the adjustment assembly including triangular teeth (54) extending axially inwardly from the second interior surface of the second cylindrical disk, an annular second surface (56) in a planar configuration radially exterior of the triangular teeth, an aperture extending through the first cylindrical disk and the second cylindrical disk, the aperture being coaxial with the second central axis and the fifth central axis, a bolt (64) extending through the aperture, a wing nut (66) with a washer (68) holding together the first cylindrical disk and second cylindrical disk with the triangular teeth within the triangular recesses at any of a plurality of rotational orientations and also forming a washer-shaped plane between the annular first surface and the annular second surface to abate paint coming between the first cylindrical disk and the second cylindrical disk, the second central axis and the fifth central axis being in the bristle plane whereby forces on the triangular teeth and the triangular recesses are rotational rather than axial during use of the system. |
