发明名称 Soft grip handle
摘要 A handle for a paint roller frame includes an inner core made of a substantially rigid plastic material and an outer grip made of a softer rubber-like material surrounding the inner core and extending part way around both ends thereof. At the outer end of the inner core is an internally threaded opening surrounded by a planar end wall. The outer grip includes an outer end portion overlying the planar end wall which acts like a locking washer, resisting unscrewing of an extension pole from the threaded opening when the extension pole is screwed down tight and a flange at a base of the extension pole threads comes into contact with the outer end portion of the outer grip overlying the planar end wall.
