ABSTRACT:
An extension handle is provided for extending the reach of a tool such as a paint roller or the like. The handle includes a first end presenting an axial opening, and is provided with a locking mechanism for locking the tool on the extension handle. The locking mechanism includes a housing supported on the extension handle at the first end and including a stepped inner surface presenting a plurality of axially extending teeth. A pin is supported by the housing for shifting movement in a direction transverse to the length of the extension handle between a locked position extending into the opening and an unlocked position withdrawn from the opening, and a biasing member biases the pin toward the locked position. A release button releases the biasing member and shifts the pin to the unlocked position. The extension handle is adapted for use with a special tool having a handle presenting a free end that is sized for receipt in the axial opening of the extension handle and that includes a cavity within which the pin is received when the handle is positioned in the axial opening and the pin is in the locked position. However, through the use of adapters, the extension handle can also be used with conventional tools having handles presenting internally threaded open ends or quick-release mechanisms.
