MATINGLY INTERFITTED TOOL HANDLE AND EXTENSION FOR PREVENTING RELATIVE ROTATION

摘要

An extension pole is disclosed for use with a paint roller tool. The pole a nd handle cooperatively provide a smooth flush connection and prevent relative rotation therebetween. In particular, an end portion of the extension pole comprises a locking mechanism that is designed to releasably interconnect the paint roller tool and the extension pole via operation of a button assembly on the extension pole. The locking mechanism includes a housing presenting a narrow outer surface defined along a circle coaxial with the pole and snugly received within the paint roller handle. A wide outer surfac e spaced radially outward from the narrow surface presents a key section, which when received within a recess extending inwardly from the rear end of the tool handle, cooperates with the handle to prevent relative rotation between the tool and extension pole. Additionally, the wide surface of the extension pole, as well as the key section thereof, are designed to be flush with the gripping surface of the tool handle, thereby creating a connection that is comfortable to the user and aesthetically appealing.
