Flame dispersant canister mounting system for under-microwave location

摘要

A fire extinguisher apparatus and related system is described for automatically suppressing stovetop fires. The fire extinguisher apparatus includes a canister restrained in a first location where the canister is operable to suppress fires on a rear burner of a stovetop. The canister is biased and movable to a second location where the canister is operable to suppress fires on a front burner of the stovetop. A trigger mechanism is provided for automatically moving the canister to the second location in response to a fire on the front burner. The fire extinguisher system includes an arrangement of fire extinguisher apparatuses wherein canisters are movable between the apparatuses to prevent collisions with external obstacles.

1. A fire extinguisher apparatus for suppressing a fire comprising:
a housing comprising mounting fixtures thereon for coupling the fire extinguisher apparatus generally above a stovetop; a mandrel depending from the housing; a canister operable for automatically releasing a fire suppressant material therefrom in response to a fire adjacent the canister, the canister movably supported by the housing between a first position with respect to the housing for extinguishing fire in a first location on the stovetop and a second position with respect to the housing for extinguishing fire in a second location on the stovetop; a bottom hinge coupled to the mandrel distal from the housing and that comprises a helical top surface; a top hinge coupled to the canister and having a sliding member that interfaces with the helical top surface; and a restraining member operably coupled to the canister for restraining the canister in the first position with respect to the housing and responsive to fire in the second location on the stovetop to permit movement of the canister from the first location with respect to the housing to the second location with respect to the housing, so that when the restraining member is removed the top hinge is rotated about the mandrel to swing the canister into the second position.
