JPS58142088A - Gas controller - Google Patents

Abstract

PURPOSE:To secure such a controller that has no unstable motion, by installing a click body and a ball operating this click body for clicking as well as a spring body, while opening a gas passage only after the click body is kept in a state of being clicked with certainty. CONSTITUTION:When an operating knob 7 is rotated around a rotary center shaft 11 of a click body 6 upon operation in an arrow direction, the click body 6 is set in click motion by means of a ball 18 being pressed by a pressing spring 9 and simultaneously secured forcibly to the position of each stage with the balance between forces of the ball 8, the pressing spring 9 and the click body 6. In this case, since distance D is provided between the terminal of a contactor 5 and a gas on-off valve 10, at a time when the ball 8 exists on the crest of a curved part 6a of the click body 6, the contactor 5 does never push the gas on- off valve 10 so that no gas may come out.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gas control device, and an object of the present invention is to provide a control device with good operability and a high degree of safety.

In gas appliances, there is a control device that opens and closes a gas cock located at a distance using a lever or the like, but the present invention prevents the gas opening/closing part from being opened/closed halfway due to delicate movements of the operating part, which does not compromise safety. The purpose of the present invention is to provide a gas control device with a good uJ taste.

An embodiment of the present invention will be described below with reference to the drawings.

Figure 1 and B show the operating knob in the closed state and the second knob.

B shows the configuration in which the click is at the peak position while moving the operating knob, the third prong, and B shows the configuration in which the gas is in the open state.

In each figure, 1.2 is a flexible band-shaped plate, 3 is a contact, 4 is an operating movable part, 6 is a contact that operates the gas opening/closing valve 1o, 6 is a click body, 7 is an operating knob, 8 9 is a ball, 9 is a pressing spring of the ball, and 11 is a rotation center axis of the click body 6. At the end of the chestnut body 6, there are peaks and valleys 6.
a is formed and configured to receive the ball 8.

Now operate the operation knob 7 in the direction of the arrow to click the click button 6.
Rotate around the rotation center axis 11 of.

At this time, the click body 6 is clicked by the ball 8 pressed by the pressure spring 9, and is forcibly fixed at each stage position by the balance of the forces of the ball 8, the pressure spring 9, and the click body 6. The tip of the contactor 5 presses the gas opening/closing pulp 1° to emit gas using the two strip plates 1.2.

Figures 2 and 3B show the ball 8 just stopping at the peaks and troughs 6& of the click body 6 (ffi').

Although such a state is rare, if gas is released in this state, the ball 8 will move due to subsequent vibrations, and the click body 6 will move, resulting in an open state or an open state. Such an unstable state must be avoided at all costs, and for this purpose a space is provided between the end of the contactor 5 and the gas switch pulp 10. In other words, the ball 8 has the click body 60 and the peaks and valleys 6.
When it is at the peak of 1L, the contactor 6 never presses the gas opening/closing valve 10'i so that gas does not come out. Therefore, the gas will only flow out in the position shown in FIG. The gas opening/closing pulp 10 may be configured to open wide with a small stroke.

As described above, according to the present invention, the gas flow path is opened only after the click body is reliably maintained in the clicked state, so that a stable device without unstable operation can be provided.
