Abstract
The present invention provides for a pneumatically operated retractable lighting assembly that is adapted for insertion into the ground, existing ceilings, or the like. The pneumatically operated retractable lighting assembly includes a first housing that receives a second housing. The second housing is in a slidable relationship to the first housing. The second housing further supports the light fixture. When the device is activated, air is supplied to the first housing in order to lift and activate the second housing and current is supplied to the light fixture. During deactivation, the air escapes the first housing to permit the second housing to retract into the first housing while current is no longer supplied to the light fixture.
Claims20
A device that provides illumination when in use and which retracts into a base when not in use comprising:
- a first housing having an enclosed bottom and an opened top;
- a first flange is located on a periphery of said open top to provide for said first flange to be flushed with said ground when said first housing is buried in a base;
- a second housing is disposed within said opened top of said first housing and is adapted to slide through said opened top between a first position substantially retracted into said first housing and a second position at least partially extend out of said first housing;
- an illumination means is located above said second housing for providing illumination when said housing is in said second position;
- an activation means for activating and extending said second housing beyond said base;
- and
- said activation means includes a pneumatic activation means to provide for air to force said second housing above said first housing and said pneumatic activation means includes an air compressor for enabling air to raise said illumination means by providing air to lift said second housing to said second position and a releasing means for enabling the air to be released for enabling said second housing to be lowered to said first position.
A device that provides illumination when in use and which retracts into a base when not in use comprising:
- a first housing is buried in a base and said first housing includes a top and a bottom;
- said top is opened;
- a second housing is disposed within said first housing and is adapted to slide through said top between a first position substantially retraced into said first housing and a second position at least partially extended out of said first housing;
- an illumination means is located on said second housing for providing illumination when said housing is in said second position;
- an activation means for activating and extending said second housing beyond said base;
- said activation means includes a pneumatic activation means;
- said pneumatic activation means includes an air inlet means and an air releasing means;
- and
- said air inlet means enables air to enter into said first housing for raising said illumination means by providing air to lift said second housing to said second position and said releasing means provides for air to be released for enabling said second housing to be lowered to said first position.
