Problems solved by technology

Therefore, if the above-mentioned gap is large, when the ignition system is in a non-operating state, its metal components collide violently with each other and generate noise, thereby giving a bad impression to the product.

Abstract

A flint-type ignition mechanism comprising a freely rotatable support member; a spark wheel combined with the supporting member so as to be integrally rotatable with same; an elastic member installed around the support member; a thumb wheel having a gear-type inner face installed around the elastic member so that it can idle, the thumb wheel switching between the concentric and eccentric position; and a disk-shaped engaging member which rotates together with the supporting member and has engagement stoppers on the peripheral surface of the exterior circumference thereof for engaging the gear type inner face of the thumb wheel. When the thumb wheel is switched to the eccentric position by a deformation of the elastic member, the stoppers engage together and the spark wheel rotates together with the thumb wheel, causing it to be in the ignite-state. In the ignite-state, rotation of the thumb wheel rotates the spark wheel for ignition.

Description

technical field [0001] The present invention relates to an ignition mechanism for a gas lighter, which uses a flint and generates sparks by rotating an ignition wheel, and more particularly relates to an ignition mechanism that realizes a non-ignition state by rotating a thumbwheel idly. Background technique [0002] Some prior art ignition mechanisms have been proposed that have a thumb wheel that is separate from the ignition wheel so that the thumb wheel can idle. However, the ignition wheel cannot be turned by simply turning the thumb wheel, making it impossible for these ignition systems to ignite in order to prevent inadvertent ignition of the flame. [0003] Ignition mechanisms for such gas lighters are disclosed in US Patent Nos. 5,547,370; 5,759,023; 5,868,561; 5,913,674; 5,971,749; These systems include ignition mechanisms in which two surfaces, a surface of the thumbwheel and a surface of the ignition wheel, are engaged by pressing and rotating the thumbwheel, an...
