Patent ID: 8356796

Claim:
A unitary damper shaft extender for HVAC air ducts, the extender comprising a unitary apparatus including y-shaped shaft connector, a longitudinally extending collar having an outer wall and a longitudinally extending, open ended bore therethrough, the bore being in cross-section being substantially complementary in size and shape to the y-shaped shaft connector to permit sliding of the y-shaped shaft connector through the bore and relative to the holder outer wall, the y-shaped shaft connector being slidably held within the longitudinal open ended bore; and locking means for preventing the removal from the holder bore of the connector, the locking means comprising a guide pin extending from one surface of the connector and a guide slot through the outer wall of the holder and extending only partially along the length of the outer wall, the pin and the guide slot being juxtaposed to allow the pin to slide along the slot for only a limited distance, as the connector is caused to slide through the bore of the holder.
