Abstract

A fire suppression system for a decorative tree, such as a Christmas tree, of the present invention wherein, disguised, for example, as a Christmas gift or incorporated as an integral part of the stand for the tree itself, there is provided a canister with a dry, substantially inert chemical, such as Halon, or similar fire suppressant substance, is disclosed. The fire suppressant substance is forced, e.g., by the application of pressure, when a heater smoke-sensitive sensor, released by a solenoid valve, is used to project the dispersant through a tubular plenum to a dispersant nozzle contained within, or as an integral part of, an ornament, e.g., a star, atop of the decorative tree. The flow of the fire suppressant fluid is preferably directed outward from a plurality of oval-shaped holes, preferably at least four such oval-shaped holes, which encircle a cylinder-type nozzle so as to provide dispersant to all directions surrounding the tree. The use of oval-shaped dispersing holes, or exit holes, for the fire suppressant substance has been discovered to have the beneficial effect of maximizing the flow of the fire suppressant substance by properly directing in a downward and outward direction thereby efficiently covering the tree in a time-effective manner.

Claims2

Dependent claims

Apparatus for the suppression of a tree fire, upon a substantially conical shaped decorative tree comprising:

a canister capable of containing a fire suppression material;
a conduit leading from said canister for transporting therethrough the fire suppression material, said conduit having a plurality of stationary openings for permitting the exiting of the fire suppression material;
means for sensing the presence of heat or smoke;
and,
means for forcing the fire suppression material contained within said canister through said conduit to and through the plurality of openings of said conduit in order to combat a tree fire, said means for forcing being activated in response to said sensing means sensing the presence of heat or smoke;
means for directing said fire suppression material outward and downward over the substantially conical shaped decorative tree, said means being said plurality of openings being oval shaped and said openings having a horizontal diameter which is greater than a vertical diameter;
said means for sensing the presence of heater smoke includes a plurality of heat/smoke detectors which encircle a tree;
said means for forcing the fire suppression material contained within said canister through said conduit includes a solenoid valve;
an electrical control relay connected within said conduit, said electrical control relay being capable of deactivating electrical power for a tree.
