Title:
GAS APPARATUS
Document Type and Number:
Japanese Patent JPH04174218
Kind Code:
A
Abstract:

PURPOSE: To obtain a safe gas apparatus nonignitible by the inadvertent actions other than a proper ignition operation by providing an improved ignition knob so arranged as not to permit the ignition knob to be pushed into the releasing position with any part of the body other than the hands.

CONSTITUTION: The subject gas heating device contains a locking means 6 capable of locking and releasing an ignition knob 2 against the force of a spring. A guard ring 4 is mounted around the periphery of the ignition knob 2 in such a manner that the front face of the ignition knob 2 and that of the guard ring 4 lie in almost the same plane in the locking position of the knob 2. The guard ring 4 is so sized and shaped as to permit a spherical body 5 to contact the guard ring 4 before the ignition knob 2 reaches the releasing position, when the spherical body 5 having a radius of about 60mm is held against the front face of the ignition knob 2 and pushed in. This method ensures that the ignition knob can not be pushed into the ignition position with any part of the body other than the hands and safety is maintained in the use of this device.
