Adjustable light fixture

A lighting fixture comprising:

• mounting means for supporting said fixture;
• a plurality of elongated tracks, each being mounted at one end to said mounting means, said tracks biased for movement in directions transverse to their length;
• detent means, including protrusions, serially disposed along said tracks;
• a support member for supporting a lamp assembly, said support member being provided with a plurality of detent engaging means;
• and
• rollers provided on said support member, said protrusions and rollers forming a series of overcenter arrangements, said rollers engagable between adjacent ones of said protrusions, said protrusions and said rollers being operable to engage each other to selectively position said lamp assembly with respect to said mounting means in response to the adjustment.

A light fixture comprising:

• a hollow, elongated housing having an open end and a closed end;
• a plurality of spaced-apart, resilient, elongated tracks mounted at one end to the closed end of said housing, a series of camming surfaces disposed along said tracks;
• a support member including a plate receivable within said housing for telescopic and tilting movement with respect thereto;
• lamp assembly means mounted on said support member;
• a plurality of predeterminedly spaced-apart cam engaging means mounted on said support member for engaging said camming surfaces disposed along said tracks;
• said one end of said tracks spaced-apart from each other a predetermined distance corresponding generally to the predetermined spacing of said cam engaging means, said tracks diverging downwardly and being biased outwardly, terminating at free ends;
• said support member and said cam engaging means defining a plurality of apertures for receiving respective ones of said tracks, allowing said tracks to telescope through said apertures;
• and
• said tracks deflected toward each other, against said outward bias when telescoped through said apertures, whereby said series of camming surfaces and said cam engaging means form a series of overcenter arrangements with each of said camming surfaces selectively engagable between said adjacent ones of said cam engaging means in response to the movement of said support member in said housing along said tracks.
