Abstract:
A piezoelectric gas lighter with safety device designed to prevent children from the possibility of igniting the lighter, comprising:a driven cap disposed in the upper portion of the body and spring-pressed relative to the body and movable in a direction along the body, said cap being provided with a safety device;a burner valve having a lever for its pressing-off in order to emit to the atmosphere gaseous fuel stored within the body,said cap in the upper portion being provided with a rectangular cut-out positioned perpendicularly to a longitudinal axis of said body,said safety device comprising a button in the form of a rectangular plate disposed in the upper portion of said cap and movable in guide means along said cut-out in a direction perpendicular to said longitudinal axis of the lighter body,a spring for returning said button in the initial position after the pressure applied on in on the part of a user has been removed,said button in the form of the rectangular plate being provided with protrusions directed toward a piezo-element, which protrusions are in the form of two legs located with a gap with respect to the piezo-element such that said piezo-element is positioned between said legs,said button being provided with a support member having a socket for mounting therein one end of said button spring, another end of which is brought into contact with a support on the cap,said guide means for button movement comprising longitudinal protrusions in walls of said cut-out in said cap and longitudinal grooves in side walls of the button,in the area of said piezo-element location, the body being provided with a protrusion directed toward said button, said protrusion being positioned by its height with a gap with respect to free ends of said button protrusions when the button is pressed off in its upper position,said body being provided with a support for the burner valve lever, which support is located in the area between the burner and piezo-element, to provide rocking of said lever when its free end is depressed by said button legs and to provide pressing-off of said burner valve in order to emit gaseous fuel to the atmosphere.
