Abstract
A protective system for vegetation has an underground housing from which a protective canopy can be deployed. The canopy unfurls as it is deployed and its position above ground can be adjusted after it is fully unfurled. After use, the canopy can be furled and lowered back into the housing. A liquid delivery system allows use of anti-freeze or fertilizer to be delivered via the system. Deployment of the system can be done manually or automatically in response to a selected signal.
Claims13
A system for protecting vegetation, said system comprising:
- an elongate housing body having a lower end, an upper end, and a length between said lower and upper ends, said housing body for being positioned substantially below ground level with said upper end being located proximal to ground level;
- a canopy assembly comprising a foldable canopy mounted to at least one column, said column being vertically extendable to raise said canopy;
- said canopy assembly having (i) a first, retracted position wherein said canopy assembly is fully retracted within said housing body length with said at least one column unextended;
- (ii) a second, deployed position wherein said at least one column extends beyond said length of said housing body;
- a motivator for extending and retracting said canopy assembly between said first and second positions;
- and
- a lid assembly rotatably connected to said housing body, said lid assembly having (i) an open condition to accommodate extension of said canopy assembly therethrough, and (ii) a closed condition, rotated away from said open condition, wherein said lid assembly covers said canopy assembly when said canopy assembly is in said first, retracted position.
