Automatically deploying flame suppression system

Abstract

A fire suppression system that deploys automatically in response to an open flame. The system includes a fuse, a cover, a pivot arm rotatingly coupled to the cover, and a canister secured to the pivot arm. Helical walls extend downward from the pivot arm that rest on the ends of fingers that attach to the cover. The fuse, when intact, interferes with relative rotation of the pivot arm with the cover. The fuse becomes degraded when combustion is initiated from exposure to the open flame. Degrading the fuse allows the pivot arm to rotate and position the canister over the flame, which causes the canister to release a fire suppressing agent that extinguishes the flame. A spring biases the arm away from the cover, without the fuse, the arm rotates and moves downward due to interaction of the fingers with the helical walls.
