Benefits of technology

The locking mechanism effectively prevents accidental ignition and injury by ensuring the operating component cannot be depressed when the swing-arm is folded, maintaining safety during folding and use, thus enhancing user safety.

Problems solved by technology

Due to the separation of the tip of the tip pipe emitting the flame from the body held by the user's hand, a lighter of this type can safely and easily ignite objects without burning the user, but there is a problem in that comparatively more space is required to store the lighter due to lengthening its overall dimensions.

Embodiment Construction

[0005]With the lighter described in Japanese Examined Patent H5-14172 (FIGS. 2 and 3), during folding of the extension tube, a finger can be injured or another external object can be damaged by compression between the extension tube and the operating component. Also, there is a danger of ignition by inadvertent pressing of the button.

[0006]Based on the above information, it is an object of the present invention to provide a safe, foldable lighter that prevents accidental ignition by inadvertent pressing of the button when folding the swing-arm to make the lighter compact.

[0007]A foldable lighter comprising:

[0008]a body that contains a fuel tank and a piezoelectric unit and has an operating component exposed to the outside for simultaneously operating the aforementioned piezoelectric unit and a fuel supply valve that controls supply of fuel from the fuel tank;

[0009]a swing-arm pivotally connected to one end of the lighter body and containing a flame-emission nozzle in the vicinity of...

Abstract

A foldable lighter having a safety mechanism for preventing inadvertent ignition. The foldable lighter comprises a body that has an operating member for igniting the lighter, and a swing-arm pivotally connected to the body by a swing-mount. The locking mechanism comprises an arcuate protrusion on an annular wall of the swing-mount, which interferes with operation of the operating member through a predetermined rotation of the swing-arm.

Description

STATEMENT OF PRIORITY[0001]This is a continuation application of Ser. No. 12 / 065,157, filed Mar. 18, 2008, which claims priority to PCT / IB06 / 04143, filed Aug. 31, 2006, which claims priority to Japanese Patent Application 2005-254868, filed on Sep. 2, 2005.FIELD OF THE INVENTION[0002]This invention relates to a lighter (igniter) that drives a piezoelectric unit by activating an operating component and that emits a flame from the tip of a swing-arm that extends from the lighter body. In particular, the invention relates to a foldable lighter, which is provided with a swing-arm that is pivotally attached to the lighter body.DESCRIPTION OF THE PRIOR ART[0003]Lighters have been used for lighting gas burners and igniters for solid fuels and fireworks. An example of such a lighter is a well known lighter (Japanese Unexamined Patent H9-133359) that has a tip pipe (extension) extended in a rod-shape from the body for emitting a flame. In its body, the lighter has a gas tank and a piezoelect...
