  • Patent number: 7524124
    Abstract: A paint roller (10) has a frustoconically-shaped applicator (12), a paint-absorbable member (14) and a movement coupler (16). The applicator (12) has a coupling portion (18) and two opposite ends (20, 22) and is rotatable at the coupling portion (18) about a rotary axis (24). The end (20) is a coupling end (20) that has a planar cross-section smaller than that of the other end (22). The coupling portion (18) is formed at the coupling end (20) and is disposed centrally thereat. The movement coupler (16) has a rotary connecting portion (40) that is detachably coupled to the applicator (12) at the coupling portion (40) that is detachably coupled to the applicator (12) at the coupling portion (18) for rotary movement about the rotary axis (24) and a pivotal connecting portion (42) that is adapted to coact with a pivot mount of a handle (not shown) for pivotal movement of the applicator (12).

  • Patent number: 6922866
    Abstract: A paint roller (10) has a paint applicator (12), two holder mounts an applicator holder (14). The paint applicator (12) has a cylindrical outer surface and two opposite ends (18a,18b). The two holder mounts, respectively associated with the two opposite ends (18a, 18b), each has a base surface (24) and a journal (26) that protrudes from the surface (24) away from the paint applicator (12). The applicator holder (14) has a handle (40) and a fork (42) with opposite sides (44,48) that each has a journal engagement portion (48,50). In a preferred embodiment, each of the holder mounts has holder abutments, (30) that protrude from the surface (24) away from the paint applicator (12). In an alternate embodiment, the applicator holder (14) has applicator abutments that protrude from mount abutment surfaces of each of two journal engagement portions towards the paint applicator (12).
