Abstract:
1. An adjustable adaptor assembly for converting a can light of the type having an opening into an interior portion thereof defined by interior electrically conductive surfaces and having an Edison-screw electrical socket having screw-threads intended for receiving a light-producing lamp or device, the adjustable adaptor assembly adapting the can light to accept an auxiliary fixture, said assembly comprising: an extensible assembly including a stem-member adjustably and telescopically received within a stem-receiver along an assembly axis, the stem receiver including an internal axially extending bore for receiving the stem-member for relative telescoping movement between a fully extended position and at least one other position, said stem-member having an elongated slot formed therein having a length dimension substantially parallel to the assembly axis, said stem-member having a base member having screw-threads for mechanical and electrical engagement with the Edison-screw electrical socket of the can light, said stem-receiver having structure for mating with a cross-bar; a mechanical member having a first end fixed to said stem-receiver and a second end extending into the elongated slot in said stem member to limit relative axial movement between the stem-member and the stem-receiver to a distance not greater than the length dimension of the elongated slot and engage with an end of the elongated slot when the stem-member is in its fully extended position to prevent the stem-member from separating from the stem-receiver; said stem-member having a plurality of serrations or teeth thereon defining a corresponding plurality of axially spaced detent positions along said stem-member; a resilient spring member connected to the stem-receiver yieldably engaging at least a one of the plurality of serrations or teeth to maintain the positional relationship of said stem-member and said stem-receiver, whereby the application of an axially directed force causes the resilient spring member to yieldably move from a current detent position to another detent position and thereagain maintain the positional relationship of said stem-member and said stem-receiver thereat; a unitary resiliently biased electrically-conductive spring-wire connected at one end thereof to said stem-member, the spring-wire extending to a remote end thereof and having a length thereof sufficient for the remote end of said spring-wire to electrically contact an interior electrically conductive surface of the can light as said base member of said stem-member is rotated into the electrical socket of the can light, the remote end of the spring wire configured to slide along the interior electrically conductive surface of the can light while resiliently maintaining electrical contact therewith as the base member is further rotated to a full mechanical and electrical engagement with the electrical socket of the can light, an electrical wire connected to said resiliently biased electrically conductive spring-wire at the one end thereof and of sufficient length to connect to a ground portion of an auxiliary fixture.
