The pin 06 is passed through a pair of vertical holes 61 and 71 symmetrically drilled in the concave and convex joining portions of the two cylindrical bodies 6 and 7 to connect the two cylindrical bodies 6 and 7.

The diameter of the pin 06 is smaller than the width of the holes 61, 71, and the pin 06 loosely fits into both the holes 61, 71.
In order to ensure the operation of the present invention, which will be described later, 1 has a tapered lower end and a shape that widens at the upper end.

Reference numeral 09 denotes a circular plate which is firmly fitted into the main body 01 and into which the second cylinder 7 is rotatably fitted, supporting the first cylinder 6 and supporting the second cylinder 7. A predetermined torque is applied to the second cylindrical body 7 by a frictional resistor 091 which is a sealing material installed at the insertion point.

91 is a ring-shaped stopper on which both ends of the pin 06 slide on the inner periphery when the pin 06 rotates horizontally at the lower end position of the elongated holes 61, 71, and a stop piece 911 that receives and stops the pin 06 is placed symmetrically on the inside. A pair of protruding pieces 912 are provided on the outside, and a circular arc notch 9 is provided on the main body 01 to correspond to the protruding pieces 912.
2, the rotation range is set in order to absorb the deviation in the stopping angle of the pin 06 that occurs when the pin 06 is stopped by the left and right sides of the stopper piece 911.

A cam surface is disposed in a lower chamber inside the main body 01 divided by the annular plate 09, which is stepped integrally with the second cylindrical body 7 and which presses and drives the valve shaft as it rotates.1. The cam surface 72 is the first gas valve 3
, the cam surface 73 is the pilot gas valve 2, and the cam surface 74 is the second
Gas valve 4 is opened.

051 is a conical bearing in which a pressing shaft 05 is fitted in the center thereof so as to be able to move up and down, and supports the second cylindrical body 7.

80 is a spring that always biases the operating shaft 03 in the upward direction.

A spring 81 is interposed between the bottom of the cavity 75 in the upper part of the second cylindrical body 7 and the pin 06, and constantly biases the pin 06 in the upward direction.

A spring 82 is installed in the cavity 76 at the bottom of the second cylindrical body 7 with its lower end supported by a bearing 051 and its upper end fixed to the pressing shaft 05, and constantly urges the pressing shaft 05 in the upward direction.

A spring 83 is provided between the connecting body 5 and the first cylindrical body 6, and constantly urges the connecting body 5 in the upward direction.

In addition, in the figure, numeral 08 is an igniter, and 10 is a gas inlet.

Next, the operation of the present invention will be explained.

When the operating knob 02 is at the stop position, the spring 83 holds the protrusion 51 at the upper end of the downward path a of the groove 07, and the pin 06 is located at the upper end of the elongated holes 61, 71. At the same time, each valve body is closed by a spring provided on the back surface.

If the operating shaft 03 is pushed down from this point, the operating shaft 03 will move to the protruding piece 5.
1 is pushed into the main body 01 to the position of the lower end of the descending path a,
The pressing shaft 05 simultaneously descends via the rotating shaft 04, presses the electromagnetic safety valve shaft 12, and thins the electromagnetic safety valve 1.

In this state, if the knob 02 is rotated 90 degrees to the left, the rotational force is transmitted to the first cylindrical body 6 via the linking body 5, and the second cylindrical body 7 is also rotated in conjunction with the pin 06, so that the cam surface 73, the pilot gas valve 2 is opened, the igniter 08 is activated, and the pilot burner is ignited.

During this time, the pin 06 is guided to the mountain 901, and the long holes 61, 71
reaches the lower end of .

Now, after the electromagnetic safety valve 1 is kept open by a sufficient thermal electromotive force, when you release your hand from the knob 02 and release the pressing force, the operating shaft 03 is moved by the spring 80, the linking body 5 is moved by the spring 83, and the pressing shaft 05 is moved by the spring 80. Each is raised by the spring 82 and returned to its original height position, and the pressure on the electromagnetic safety valve 1 is released.

If the knob 02 is further rotated to the left, a predetermined torque is applied to the second cylindrical body 7, so a pressing force in the opposite direction is applied to the pin 06 from both cylindrical bodies 6, 7. The stopper 91 rotates horizontally against the spring 81 while being held by the stopper 91.
The knob 02180 is prevented from rotating by the stopper 911.
(see Figure 4.1).

During this time, the cam surface 72 presses and drives the first gas valve shaft 32 against the spring 33 to open the first gas valve 3.

If you let go of knob 02 and release the rotating force, pin 06
The clamping between the two cylindrical bodies 6 and 7 is released, and the pin 06 is held by the spring 8.
1 and reaches the upper ends of the elongated holes 61 and 71, and the knob 02 becomes rotatable.

Further, when the knob 02 is turned to the left, the cam surface 74 opens the second gas valve 4, and the pin 06 is again inserted into the elongated hole 61 by the ridge 901.
, 71, and the protruding piece 51 of the linking body 5 is guided to the lower end of the groove 07.
The knob 02 reaches the end of the upper horizontal path d and stops at the 2700 position.

Now, in the extinguishing process, if the knob is rotated to the right from the 02270° position, the pin 06 will rotate horizontally at the lower end position of the elongated holes 61 and 71 while being held between the two cylinders 6.7, as described above. ,
The stopper 911 prevents the knob from rotating at the 02180° position (see Figures 4 and 2).

At this point, if you release your hand from knob 02 and release the rotational force, the pin 06 will be released, the pin 06 will reach the upper end of the elongated hole 61.71, and the knob will be able to rotate again. If it deviates, rotation is blocked at the knob 0290' position, and the push and turn operation returns it to the original stop position.

As described in detail above, the present invention has an operating device in which the opening and closing of the first gas valve and the second gas valve are separated by knobs at 180° positions. By once being prevented from rotating at the 180° position, knob 1
By having the operator confirm the 80° position, malfunctions can be completely prevented.

In addition, at this 180° position, the blocking is reliably released simply by removing the hand from the knob, and the simple operation is sufficient and there is no operational inconvenience. Since the rotation prevention mechanism is cleverly placed at the 180° position, the operating knob stops every 90' of reciprocating motion, making it possible to operate and control gas appliances reliably and safely without visual confirmation. It is possible to obtain an operating device for a gas appliance that has the following functions.
