Pneumatic landscape light
First Claim
1. An in-ground, pneumatically-operated, extensible and retractable landscape light comprising:
- a) an elongated outer housing adapted to be at least partially buried in a surrounding volume of ground, the outer housing having an upper end with an opening therein, a lower end, an inner surface, and an outer surface;
b) an elongated inner housing having an upper end a lower end, and an outer surface the inner housing being received into the opening in the upper end of the outer housing in a telescoping, mating relationship and being at least partially within the outer housing when in a retracted position and projecting at least partially outside the outer housing when in an extended position;
c) an inlet in the outer housing for allowing air to be injected into the outer housing for pneumatically forcing the inner housing to an extended position; and
d) a light source operably connected to the elongated inner housing for illuminating an area of landscape surrounding the light.

Abstract
An in-ground, pneumatically-operated, extensible-and-retractable landscape light comprised of an elongated outer housing having an air inlet in its body and an opening in its upper end into which is received in a telescoping, mating relationship an elongated inner housing which has a light source operably connected to the upper end thereof. The light source may be comprised of a light bulb and a source of electrical power, and the light source may be sheltered by an interchangeable light source sheltering unit. In use, the injection of air into the outer housing through the air inlet raises the inner housing from its retracted position to its extended position. The inner housing may be selectively locked in its extended position by a locking mechanism such as a solenoid with a solenoid plunger attached to one housing and a notch for receiving the plunger in the other housing.

6. An in-ground, pneumatically-operated, extensible and retractable landscape light comprising:
-
a) an elongated outer housing adapted to be at least partially buried in a surrounding volume of ground, the outer housing having an upper end with an opening therein, a lower end, an inner surface. and an outer surface; b) an elongated inner housing having an upper end and a lower end, the inner housing being received into the opening in the upper end of the outer housing in a telescoping, mating relationship and being at least partially within the outer housing when in a retracted position and projecting at least partially outside the outer housing when in an extended position; c) an inlet in the outer housing for allowing air to be injected into the outer housing for pneumatically forcing the inner housing to an extended position; d) a light source operably connected to the elongated inner housing for illuminating an area of landscape surrounding the light; and e) a means secured to the light for selectively locking the inner housing in the extended position of the inner housing whereby the inner housing may be held in an extended position without a constant influx of pressurized air when the locking means is activated, and the inner housing may be allowed to retract when the locking means is deactivated. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)
