Abstract:
A safety catch for a gas burner having a gas supply device connected to a storage barrel, the gas supply device including a flow control valve, an extensible control valve, a gas jet and a piezoelectric apparatus, the safety catch comprising:a) a casing covering the gas supply device; b) a press element movably mounted on the casing and including a press chamber receiving a portion of the extensible control valve, a press tenon engaging the piezoelectric apparatus, an extending press stem with a lateral engaging projection and a fixing base on a bottom of the press element; c) an engaging element mounted on the fixing base so as to be movable relative to the press element, the engaging element including a tilt lock plate with a lock hook; and, d) a catch element movably mounted on the casing so as to be movable between a locked position and an unlocked position, the catch element including a push key located exteriorly of the casing, a step seat with a lateral protrusion and a plate tenon spaced from the lateral protrusion, whereby, when the catch element is in the locked position, the lateral protrusion contacts the press stem thereby preventing movement of the press element which prevents opening of the extensible control valve and actuation of the piezoelectric apparatus, and engagement of the plate tenon with the lock hook on the engaging element prevents movement of the catch element from the locked position, and, when the engaging element is moved relative to the press element, the lock hook is disengaged from the plate tenon, enabling the catch element to be moved to the unlocked position thereby disengaging the lateral protrusion from the press stem enabling movement of the press element relative to the casing, such movement opening the extensible control valve and actuating the piezoelectric apparatus to ignite the gas burner.
