Abstract:
A safety device for a gas burner, comprising:a securing member in the form of a seat member fixedly provided above a liquefied gas container, one side thereof having a bearing means projecting therefrom and an opposite side thereof having a wall edge, a connecting means and a pivotal connecting means being disposed between said wall edge and said bearing means, said securing member having a surface;a press member in the form of a key member, a bottom portion of one side thereof being connected to a retractable element and insertably disposed in said bearing means such that said press member can be longitudinally displaced therewithin, an opposite side of said press member being provided with a vertically extending stop piece, a bottom side thereof having a lap piece extending laterally therefrom;a slidable member in the form of a plate, one side thereof having a sliding means connected to a retractable element and said connecting means such that it can be horizontally displaced along the surface of said securing member, a bottom portion of an opposite side of said slidable member being provided with a connecting rod, a front end thereof having an abutting rod extending therefrom, said connecting rod abutting against said lap piece such that a clearance is defined between said abutting rod and said stop piece, a trigger rod further extending horizontally from said slidable member;a retaining member in the form of a plate, a middle section thereof having a slide means connected to a retractable element and said pivotal connecting means such that it can be horizontally displaced along the surface of said securing member, said retaining member having a fastening rod extending from an inner side thereof;a button member in the form of a push button, said button member straddling said bearing means, a bottom edge thereof being blocked by said stop piece, and having two side walls respectively provided with a wall hook and a wall rod;said press member being manipulated downwardly to reduce the height thereof so that said connecting rod of said slidable member displaces as a result of loss of support from said lap piece, with said abutting rod contacting said stop piece, said connecting rod laps the upper portion of said lap piece so that said press member cannot bounce back and be positioned; when said press member is manipulated downwardly, said button member is pressed, an ignition means is simultaneously actuated, and said wall hook causes a gas supply means to supply fuel gas to a burner device, the fuel gas being ignited by means of said ignition means, and said wall rod abutting against said trigger rod; by pressing said retaining member, said fastening rod fastens said gas supply means in position to maintain supply of fuel gas; after use, said button member returns to its original position and is automatically retained by said press member.
