Tool handle with locking assembly

An apparatus for use in extending the reach of a tool, wherein the tool includes a handle presenting an open end that is internally threaded, the apparatus comprising:

• an elongated extension handle including a first end presenting an axial opening;
• a generally tubular housing supported on the extension handle at the first end and including an inner surface that is stepped, the inner surface presenting a large diameter section sized for receipt on the extension handle and a small diameter section extending axially from the first end of the extension handle, the small diameter section presenting a plurality of axially extending teeth spaced circumferentially from one another;
• a pin 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to the length of the extension handle between a locked position extending into the opening and an unlocked position withdrawn from the opening;
• a biasing means for biasing the pin toward the locked position;
• a release means for releasing the biasing means and shifting the pin to the unlocked position;
• and
• an adaptor including a first end that is externally threaded for receipt in the open end of the tool handle and a second end that is sized for receipt in the axial opening of the extension handle,
• the second end of the adaptor including an outer circumferential surface in which a cavity is formed, the cavity being aligned with and receiving the pin when the adaptor is positioned in the axial opening and the pin is in the locked position so that the adaptor is prevented from being pulled from the extension handle,
• the circumferential surface of the second end of the adaptor including at least one axially extending tooth that engages the teeth on the small diameter section of the housing when the adaptor is positioned in the axial opening so that the adaptor is prevented from being rotated relative to the extension handle.

An apparatus for use in extending the reach of a tool, wherein the tool includes a handle presenting an open end sized for receipt of a first extension handle and a quick release mechanism for releasing the first extension handle from the tool, the apparatus comprising:

• an elongated second extension handle including a first end presenting an axial opening;
• a generally tubular housing supported on the second extension handle at the first end and including an inner surface that is stepped, the inner surface presenting a large diameter section sized for receipt on the second extension handle and a small diameter section extending axially from the first end of the second extension handle, the small diameter section presenting a plurality of axially extending teeth spaced circumferentially from one another;
• a pin supported by the housing for shifting movement in a direction transverse to the length of the second extension handle between a locked position extending into the opening and an unlocked position withdrawn from the opening;
• a biasing means for biasing the pin toward the locked position;
• a release means for releasing the biasing means and shifting the pin to the unlocked position;
• and
• an adaptor including a first end that is sized for receipt in the open end of the tool handle and is adapted for engagement by the quick release mechanism, and a second end that is sized for receipt in the axial opening of the second extension handle,
• the second end of the adaptor including an outer circumferential surface in which a cavity is formed, the cavity being aligned with and receiving the pin when the adaptor is positioned in the axial opening and the pin is in the locked position so that the adaptor is prevented from being pulled from the second extension handle,
• the circumferential surface of the second end of the adaptor including at least one axially extending tooth that engages the teeth on the small diameter section of the housing when the adaptor is positioned in the axial opening so that the adaptor is prevented from being rotated relative to the second extension handle.

An adaptor for use in adapting a tool for use with an extension handle, wherein the tool includes a handle presenting an open end that is internally threaded and the extension handle includes a first end presenting an axially extending opening having a non-circular cross-sectional shape presenting a plurality of axially extending teeth, a pin supported 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, a biasing means for biasing the pin toward the locked position, and a release means for releasing the biasing means and shifting the pin to the unlocked position, the adaptor comprising:

• a first end that is externally threaded for receipt in the open end of the tool handle;
• and
• a second end that is sized for receipt in the axial opening of the extension handle and includes an outer circumferential surface in which a cavity is formed, the cavity being aligned with and receiving the pin when the adaptor is positioned in the axial opening and the pin is in the locked position so that the adaptor is prevented from being pulled from the extension handle,
• the circumferential surface of the second end of the adaptor including at least one axially extending tooth that engages the teeth on the housing when the adaptor is positioned in the axial opening so that the adaptor is prevented from being rotated relative to the extension handle.
