Adjustable lighting fixture
View Patent ↗An adjustable lighting fixture has a moveable housing. A first housing has a first opening and a second opening. A second housing is adapted to movably engage the first housing. A resilient member is connected to the second housing and adapted to be received by one of the first and second openings in the first housing. The first opening corresponds to a contracted position of the lighting fixture and the second opening corresponds to an expanded position of the lighting fixture. A lamp disposed in the lighting fixture has a longitudinal axis that is substantially perpendicular to a direction of movement of the first and second housings.

2. An adjustable lighting fixture according to claim 1 , wherein
said resilient member is integrally formed with said second housing.
3. A lighting fixture according to claim 1 , wherein
said first and second housings are moveable with said lamp disposed in said adjustable lighting fixture.
4. A lighting fixture according to claim 1 , wherein
a boss extends outwardly from a lower surface of said first housing; and
a slot in said second housing extending in a direction of movement of said first and second housings, said slot receiving said boss.
5. A lighting fixture according to claim 4 , wherein
a bore extends through said boss and receives a fastener to secure said second housing to said first housing.
6. A lighting fixture according to claim 5 , wherein
a channel is disposed beneath said second housing, said fastener extending through said channel, through said slot in said second housing and through said bore in said boss in said first housing.
7. A lighting fixture according to claim 6 , wherein
said channel is substantially U-shaped.
8. A lighting fixture according to claim 6 , wherein
sockets secured to said channel receive said lamp.
9. A lighting fixture according to claim 1 , wherein
said first and second housing are made of steel.
10. A lighting fixture according to claim 1 , wherein
said longitudinal axis of said lamp is in a first plane substantially parallel to a second plane in which said first and second housings are moved.
11. An adjustable lighting fixture, comprising:
a first housing having a first base, and first, second and third walls extending substantially perpendicularly from said first base;
first and second openings in said first wall;
a boss extending downwardly from said first base of said first housing, and a bore extending through said boss;
a second housing having a second base, and fourth, fifth and sixth walls extending substantially downwardly from said second base, said second housing being movably engaged with said first housing;
a slot in said second base of said second housing member extending in a direction of movement of said first and second housings, said slot receiving said boss;
a first resilient member connected to said fourth wall of said second housing and received by one of said first and second openings in said first wall of said first housing, said first opening corresponding to a contracted position and said second opening corresponding to an extended position of said adjustable lighting fixture;
a channel disposed beneath said second base of said second housing;
a fastener extending through said channel, through said slot in said second housing and through said bore in said boss in said first housing to secure the channel, and first and second housings together; and
a lamp secured to said channel, a longitudinal axis of said lamp being substantially perpendicular to the direction of movement of said first and second housings.
12. A lighting fixture according to claim 11 , wherein
said channel is substantially U-shaped.
13. A lighting fixture according to claim 11 , wherein
sockets are secured to said channel and receive said lamp.
14. A lighting fixture according to claim 11 , wherein
said first resilient member is integrally formed with said second housing.
15. A lighting fixture according to claim 11 , wherein
third and fourth openings are disposed in said third wall, and a second resilient member is connected to said sixth wall, said third opening corresponding to said contracted position and said second opening corresponding to said extended position of said adjustable lighting fixture.
