Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an igniter that ejects gas and ignites gas by an ignition operation of rotating an operating member around a fulcrum member, and normally prohibits rotating operation of the operating member. Alternatively, the present invention relates to an igniter equipped with an operating mechanism that makes ignition impossible by insufficient operation amount or reset prevention of the ignition device, while eliminating these when using.

[0002]

2. Description of the Related Art An igniter, such as an ignition rod, is convenient because it can be easily ignited by pushing an operating member, but it cannot be accidentally ignited, or accidental ignition does not occur. Thus, it is required to install a lock mechanism and the like, and up to now, an igniter having various mechanisms has been proposed.

For example, in Japanese Unexamined Patent Publication No. 8-61673, a lock member for interlocking a lock portion with an operating member to lock ignition is installed so as to be movable in a direction intersecting the moving direction of the operating member. An urging member for urging the lock member in the locking direction is arranged, and further, the lock member has a release operation portion movable against the urging member, and the release operation portion is operated by the operation member. There is disclosed an igniter having a mechanism that is provided in the vicinity of the portion.

[0004]

However, in the lock mechanism as described above, the operation of the operation member of the operation mechanism is of the slide type, and the operation member targeted by the present invention is directly applied to the rotation type. You cannot do it.

Further, in these ignition lock mechanisms, it is common for the ignition operation to operate another member at a position apart from the operation member such as the lock release member before performing the ignition operation for the operation member. Since a stepwise operation is required and its operability is difficult, it is desirable to provide such that a transition to an ignitable state and a stable ignition can be performed by a series of operations. Further, after the ignition operation, it is desired to automatically return to the initial state in which ignition is impossible with the release of the finger from the operation member.

In view of this point, in the present invention, when ignition is performed by rotating the operating member, it is possible to obtain a non-ignition state and a series of ignition operations for releasing the non-ignition state while ensuring good operability. It is an object of the present invention to provide an igniter having the above-mentioned operating mechanism.

At this time, the lock member is provided on the main body case or the linking member in a projection shape that interferes with an engaging portion provided on the linking member or the main body case, and when the lock is released from the engaging portion, the linking member is released. Alternatively, the linking member may be configured to pass through a groove formed in the main body case to allow rotation.

Further, the urging member includes a pressing member that slides according to the movement of the operating member in the unlocking direction, and a spring that urges the pressing member, and the operating member is provided on the pressing member. It is preferable that a part of each of them is provided so as to be slidably in contact with the rotation thereof.

On the other hand, the second type operation mechanism includes a rotatable operation member, a fulcrum member serving as a rotation center of the operation member and supported by the main body case, and a rotation member according to the rotation of the operation member.

You are getting the desired functionality.

For example, in the one having the operation mechanism of the first system, when the operating member is in the non-operated state and is in the lock position by the biasing member, the lock member is in the ignition locked state in which the operation is performed, and the operation is performed. Rotational operation of the member is prohibited. Then, when the operating member is operated in a direction different from the rotating operation against the biasing member and the lock is released, the lock member is disengaged, whereby the rotating operation of the operating member becomes possible, and the ignition operation is performed. Ignition is performed on the fuel gas ejected as a result. When the operation of the operating member is released, the operating member is returned and rotated, and the operating member is moved to the ignition lock state by the bias of the biasing member and automatically returns.

Further, in the one having the second type operation mechanism, when the operation member is simply rotated without being assisted, the interlocking member accompanying the rotation operation of the operation member is used. The operation amount of the ignition device is smaller than the operation amount up to the discharge position and the ignition cannot be performed without discharging.

When it is rotated, it cannot be ignited without being discharged by the ignition device.
Auxiliary operation is performed on the operating member in a direction different from the rotating operation direction to operate the ignition device to the reset position against the reset blocking member, and then the rotating operation is performed to cause discharge and ignition of the ejected fuel gas. Done. When the operation of the operating member is released, the operating member is returned and rotated, and is automatically returned to the position requiring the auxiliary operation.

[0021]

According to the igniter of the present invention, before and after the turning operation of the operating member, it is necessary to perform an auxiliary operation of the operating member in a direction different from the turning operation. Inadvertent ignition can be prevented by making it difficult for an unknown person to shift to the ignitable state, and it can be left in the ignitable state by automatically returning to the initial state where ignition is not possible at the time of return movement. Therefore, in the extinguishing state, it is possible to secure a reliable non-ignitable state and improve reliability. In addition, the auxiliary operation and the rotating operation of the operation member can be performed in cooperation with each other, and the ignition operation can be performed in a series rather than in a multi-step operation, and excellent operability and stable ignition can be obtained.
