Extension pole mechanism for paint roller

摘要

An extendable pole mechanism may be used with a pair of poles that are longitudinally movable to adjust the overall length of both poles. The mechanism may include a collar that receives the poles and a roller sleeve that rotates with respect to the collar to adjust the mechanism between a use condition, where the poles are held in a longitudinally relative fixed position, and an adjustment condition, where the poles are longitudinally moveable with respect to each other.

1. An extendable pole mechanism for use with a first associated pole that is longitudinally movable with respect to a second associated pole to adjust the overall length of both poles, the extendable pole mechanism comprising:
a collar that: (1) receives the first and second associated poles; and, (2) contacts the second associated pole to prevent substantial relative longitudinal motion of the second pole with respect to the collar; a roller cage that: (1) has at least one roller; (2) receives the first associated pole; and, (3) is rotatable with respect to the first associated pole; a roller sleeve that: (1) receives the roller cage; (2) is rotatable with respect to the roller cage; (3) is attached to the collar; and, (4) is rotatable with respect to the collar; and, wherein the extendable pole mechanism is adjustable by rotating the roller sleeve with respect to the collar and with respect to the roller cage between: (1) a use condition where the first associated pole is held by contact with the at least one roller in a longitudinally substantially fixed position with respect to the second associated pole; and, (2) an adjustment condition where: (a) the first associated pole is not held by contact with the at least one roller in a longitudinally substantially fixed position with respect to the second associated pole; and, (b) the first associated pole is longitudinally moveable with respect to the second associated pole.
