Abstract
A fire extinguishing system for a Christmas tree including a base defining a water reservoir and having a submersible pump and container holding a fire extinguishing foam material mounted in the reservoir. A venturi block mixes the fire extinguishing foam material with water pumped from the reservoir upon detection of a fire condition by sensors scattered throughout the tree which mixture is discharged through a spray head mounted at the top of the tree. A relay connected to the fire sensors simultaneously closes an electric circuit to the pump and opens an electric circuit to the Christmas tree lights when the fire condition is sensed.
Claims14
A fire extinguishing system for a Christmas tree comprising:
- a tree stand defining a water reservoir;
- a submersible pump mounted in said reservoir;
- a conduit connected to an outlet from said submersible pump, said conduit adapted to extend upwardly through said tree and having an outlet end proximate a top of said tree;
- a spray head mounted to said outlet end of said conduit orientated for directing said water downwardly into said tree;
- means for sensing a fire condition in said tree;
- means responsive to said means for sensing said fire condition for actuating said submersible pump.
A fire extinguishing device for a Christmas tree comprising:
- a tree stand including a water reservoir;
- a submersible pump mounted in said reservoir;
- a container including a fire extinguishing foam material mounted in said water reservoir;
- a conduit connected to an outlet from said submersible pump, said conduit adapted to extend externally of said reservoir upwardly through said Christmas tree, said conduit having an outlet positionable near a top end of said tree;
- a spray head connected to said conduit at the outlet from said conduit for directing a mixture of said water and said fire extinguishing foam material onto said Christmas tree;
- means for mixing said fire extinguishing foam material with said water for mutual discharge through said conduit to said spray head;
- means for sensing a fire condition in said tree;
- and
- means responsive to said means for sensing for actuating said submersible pump.
A fire extinguishing system for a Christmas tree comprising:
- a hollow base including means for holding said Christmas tree upright;
- a normally closed solenoid valve mounted in said hollow base, said solenoid valve including an inlet and an outlet;
- means for connecting an external garden hose to said inlet of said solenoid valve;
- a conduit connected to said outlet from said solenoid valve adapted to extend externally of said base upwardly through said Christmas tree, said conduit including a spray head at an upper end orientated for directing a fire extinguishing material downwardly into said Christmas tree;
- means for sensing a fire condition in said Christmas tree;
- means responsive to said means for sensing for opening said normally closed solenoid valve.
