DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1A is a system diagram of a safety device for a cooking device. In FIG. 1A, 101 is a gas table casing as a cooking device, and 102 is an ignition / fire extinguishing operation body as an ignition / fire extinguishing operation means for operating a gas cock. FIG.
In (b), 102a is a first operating body as a first operating means forming the ignition / extinguishing operating body 102, and 102b.
Similarly, is a second operating body as a second operating means for forming the ignition / extinguishing operating body 102. When the first operating body 102a is integrated with the second operating body 102b, the stroke d1 between the first operating body 102a and the housing 101 is as shown in FIG.
Is too small to operate as a gas cock. When the second operating body 102b has a shape that largely protrudes from the first operating body 102a as shown in FIG. 1D, a stroke d2 with the housing 101 as shown in FIG.
Becomes larger, and sufficient operation is possible to operate the gas cock.

In FIG. 1G, the second operating body 102b
Has its own guide 103 and an engagement pin 104 inside the guide 103, and the engagement pin 104 can be engaged by a spring 105. In FIG. 1 (f), the first operating body 102a is engaged with the engaging pin 104 of the second operating body to be fixed, and the concave portion 106 and the engaging pin 10 from the concave portion 106.
There are a releasing body 107 having a working rod 107a for pushing the 4 to disengage, and a return spring 108 for pushing back the releasing body 107. The engaging pin 104, the spring 105 and the recess 106 form a fixing means. When the operating means is integrated as shown in FIG. 1B, the engagement pin 104 is in engagement with the recess 106. Here, after the action rod 107a of the releasing body 107 is pushed out and the engagement pin 104 is pushed in, the second operating body 102b can perform the protruding operation along the guide 103 thereof. Then, by rotating and fixing the slit 103a in the guide 103, the stroke d2 is removed, and the ignition of the gas cock is enabled. In this way, the operating bodies 102a and 102b are operated by operating the releasing body 107 at two locations.
It is difficult for a child to operate the device by requesting the operation of releasing the engagement of the device, rotating the guide 103, and then pushing it in.

Next, another embodiment will be described. Figure 2
In the figure, 110 is a connecting rod as a connecting means for connecting the ignition / extinguishing operation body 102 and the gas cock, and 110 a is a closing projection as a first closing means provided in a part of the connecting rod 110. Reference numeral 111 is a closing body as a second closing means for preventing the force from the ignition / fire extinguishing operation body 102 from being transmitted to the gas cock by acting on the closing projection 110a.
The closing body 111 is the operation panel unit 1 on the front surface of the housing 101.
It has two operating parts, that is, a first operating part 111a and a second operating part 111b, which project through the through holes provided in the device 12. And normally, the closing body 111 is close to the connecting rod 110, and the projecting portion 111c abuts on the closing protrusion 110a. When it is desired to ignite, the first operation section 111a and the second operation section 111b on the operation panel section 112 are lifted and hooked on the support 113 protruding from the housing 101. Thereby, the protrusion 1 of the closing body 111
11c does not hit the closing projection 110a, and the ignition / fire extinguishing operation body 102 is pushed in so that the gas cock can be opened. By holding the first operation unit 111a and the second operation unit 111b at two places, a child with a small hand cannot lift the first and second operation units 111a and 111b with one hand, preventing an unexpected operation by the child. It will be possible.

Next, another embodiment will be described. FIG.
In (a), 120 is a shield as a flexible shield, and 121 is a first fixing means for maintaining the shield at the end of the shield 120.
A fixed body 122 is a second body for fixing the shield 120 which is fitted to the first fixed body 121 on the front surface of the housing 101.
2 is a second fixing body as a fixing means, and 123 is a storing body as a storing means that pulls the shield 120 back into the housing when the first fixed body 121 is removed from the second fixed body 122. While the gas stove is normally used, the operation / panel unit 112 is arranged so that the ignition / fire extinguishing operation body 102 can be easily seen from the outside as shown in FIG. However, after use, or in an environment where a child tries to play tricks, the shield 120 is immediately pulled out from the lower portion of the housing 101, and as shown in FIG.
The two are combined to hide the operation panel unit 112. This prevents children from mischief and is safe. Further, since the portion facing the outside is flat, cleaning can be easily performed even if it becomes dirty due to dust or the like. A side sectional view in this case is shown in FIG. Shield 1 from FIG.
When 20 is outside, the container 123 is ready to be pulled back. Here, a spring is used as the storage body 123. This allows the shield 120 to be immediately pulled back to the lower part of the housing 101 at the start of use, which is convenient.

Next, another embodiment will be described. FIG.
(A) is an example of a conventional ignition / extinguishing operation body 102.
In this case, no matter where the ignition / extinguishing operation body 102 is pressed, the force is transmitted to the gas cock via the connecting rod 110.
In FIG. 4 (b), the shaft of the ignition / extinguishing operation member 102 having a hollow has a shaft end 130x in a hemispherical shape. The rod end 110x of the connecting rod 110 is also hemispherical.
The contact portions of both the end portions of the shaft end 130x and the rod end 110x are small area portions such as dots, and unless force is applied straight, the force cannot be accurately transmitted to the gas cock. ignition·
The plurality of depressions on the surface of the fire extinguishing body 102 are divided into effective depressions 130a and 130b and invalid depressions 130c. Specific depression or effective depression 130
A spring as a repulsion body 131 as a repulsion means is provided between the casings 101 and 130a and 130b. As for the arrangement of the depressions, for example, if the effective depressions are diagonally arranged as shown in FIG. 4C, the operation becomes easy. In addition, a layout that is beautiful in terms of design may be configured.

To explain the operation, first, when the ignition / fire extinguishing operation body 102 having a depression is pushed in to open the gas cock, if the two effective depressions 130a and 130b are pushed in at the same time, the shaft end 130x of the ignition / extinguishing operation article will be straightened. The force is pushed out, and its force is transmitted to the gas cock via the connecting rod 110 via the hemispherical contact points. If the depression 130c is pushed in when pushing, the ignition / fire extinguishing operation body 102 tilts, and therefore the shaft end 130x and the rod end 11 of the connecting rod.
0x has an angle and the force is correct. Connecting rod 110
Will not be transmitted to. This is because the repulsion body 131 is installed only in the lower part of the effective depression of the ignition / extinguishing operation body 102, and therefore, when the depression is pressed ineffectively, the ignition / extinguishing operation body 102 is inclined. Therefore, the gas cock cannot be opened. Therefore, it is possible for an adult with memory to judge this effective depression and invalid depression, but this judgment is difficult for a child and the gas cock cannot be easily opened, preventing manipulation by mischief, etc. Will be able to.

Next, another embodiment will be described. Figure 5
(A), 140 is a braking body as a braking means for limiting the pressing operation of the connecting rod 110, 141 is a holding body as a holding means for fixing and adjusting the position of the braking body 140, and 142 is a rotating body. Is an adjusting rod for adjusting the sensitivity of the braking body 140, that is, the friction sensitivity of the braking body 140 in contact with the connecting rod 110, and 143 is an adjusting body as an adjusting means for rotating the adjusting rod 142. 144 is a handle installed on the operation panel unit 112. When the arrangement of each part is viewed from above, it becomes as shown in FIG.

To explain the operation, normally, the ignition / extinguishing operation member 102 is pushed in with a small force. Therefore, even a child can operate it. As a method of preventing this, a certain amount of frictional force is applied to the connecting rod 110 so that the ignition / extinguishing operation body 102 is difficult to push. This will be described with reference to FIG. Adjuster 143
When the brake body 140 is rotated, the opening degree of the braking body 140 can be adjusted via the holding body 141 by the action of the screw cut at the tip of the adjustment rod 142. If a frictional force is applied to the connecting rod 110 by slightly tightening the opening degree of the braking body 140, the ignition / extinguishing operation body 102 cannot be pushed in with a normal force. Therefore, the handle 144 is held by one hand and the ignition / extinguishing operation body 102 is pushed by the other hand. This can prevent operation by a child. When the cooker is not used by installing the adjusting body 143 in a position where children cannot physically reach, the connecting rod 110 is fixed by the braking body 140 and the gas cock 14 is actually used.
Only when 9 is opened, the adjustment body 143 is rotated to rotate the braking body 1
40 may be loosened to make the connecting rod 110 movable. The number of the braking members 140 is not one, and the connecting rod 11 is not shown as shown in FIG.
It is more effective to dispose two pieces 140a and 140b on both sides of 0. Further, when the braking body 140 has a structure such as 140c shown in FIG. 5D by folding a shape memory alloy whose shape is changed by heat, for example, after the gas cock 149 is opened, ignition is performed and the surroundings become hot. And the braking body 140 are warmed, and the heat causes the shape memory alloy 14
0c is deformed so that the frictional force of the connecting rod 110 can be relaxed. This facilitates the operation of the connecting rod 110 at the time of extinguishing the fire and allows the fire extinguishing work to be performed quickly.

Next, another embodiment will be described. Figure 6
In (a), 150 is a locking body, 151 is a guide for changing the position of the locking body 150, 152 is a guide operating body for operating the guide 151, and 153 is a suction means for pulling back the guide operating body 152. Is a suction body.
The operation will be described with reference to FIGS. 6B, 6C, 6D, and 6E. Normally, the locking body 150 is positioned as shown in FIG. 6 (b), and it works so as not to push the ignition / fire extinguishing operation body 102 by acting on the closing projection 110a on the connecting rod 110. The positional relationship is as shown in FIG. When the gas cock is opened, the guide operating body 152 is pulled out to the front of the operation panel portion as shown in FIG. As a result, the guide 151 integrated with the guide operating body 152 utilizes the constricted shape of the locking body 15
The position of the locking body 150 is changed when passing through the hole portions 150b and 150c provided in 0. In this embodiment, the locking body 1 is on the right side.
50 moves. As a result, when the recess 150a provided in the upper portion of the locking body 150 moves to the position of the closing projection 110a of the connecting rod, the closing effect disappears and the ignition / fire extinguishing operation body 102 is lost.
Will be able to push. The positional relationship at this time is shown in (e) of FIG. 6, and the overall positional relationship of the cooking device is shown in (f) of FIG. This operation is normally done with one hand
Pull 2 and use the other hand to ignite and extinguish the operator 102
Since it is operated by a child, it becomes a complicated operation for a child and cannot be easily mischieved. Therefore, it becomes possible to prevent accidents caused by the operation of children.

Next, another embodiment will be described. Figure 7
, 160 is a main valve, 161 is the main valve 1
An opening / closing body as an opening / closing means for opening / closing 60, and an operation rod 162 for operating the opening / closing body 161.

The operation will be described. Normally a gas cock 149
There is a valve in this that opens and closes the gas.
Therefore, the main valve 160 remains open. In many cases, a plurality of gas cocks 149 are installed in a gas table or the like, and when all gas cocks are suddenly closed due to some accident or disturbance, a plurality of ignition / extinguishing operation bodies are individually operated, which is complicated. Therefore, the main valve 160 is installed upstream of the gas cock 149 so that it can be opened and closed. For example, when cooking a tempura or the like by a burner through a certain gas cock 149 and a fire occurs, the gas cock 149 is of course closed, but other gas cocks must be closed at the same time.
In this case, by pulling the operation rod 162 in front of the operation panel unit 112, the main valve 16 is opened via the opening / closing body 161.
0 can be closed. As a result, the gas supply to the burners located downstream of all the gas cocks can be stopped by one operation, the fire extinguishing work can be completed in an instant, and a dangerous state can be avoided. In the present embodiment, the operation rod 162 is pulled, but it is possible to realize the function by pushing it in or rotating it, and it is a condition that it can be easily operated from the operation panel unit 112.

Next, another embodiment will be described. FIG.
(A), 170 is an opening adjusting body as an opening adjusting means for adjusting the opening of the gas cock 149, and 171 is integrated with the opening adjusting body 170 and acts on the closing projection 110a on the connecting rod 110. It is a closing plate as a closing means for limiting the operation of the connecting rod 110. The closing plate 171 is shown in FIG.
As shown in (e), a recess 171a is partially formed. The operation will be described. Usually, when the cooker is not used, the connecting rod 11 is as shown in FIGS. 8 (a) and 8 (b).
There is a closing plate 171 on the gas cock 149 side behind the closing protrusion 110a at 0. Therefore, the ignition / extinguishing operation body 10
I can't press 2. When the gas cock 149 is opened and used, as shown in FIGS. 8C and 8D, the opening adjusting body 170 is positioned in parallel with the connecting rod 110, and the recessed portion provided in the closing plate 171. 171a makes it dodge the closing protrusion 110a. In this state, the opening adjustment body 1
By pulling 70 in front of the operation panel 112, the closing plate 171 can be brought forward of the closing protrusion 110a. As a result, the ignition / fire extinguishing operation body 102 can be pushed in, and the opening degree adjusting body 170 for adjusting the gas cock can also be operated. This operation requires that the opening adjusting body 170 be brought to a certain position, then pulled, and then the ignition / extinguishing operation body 102 is pushed in only when it is used. Since the relationship between the operation procedure and the position is important to some extent, it is difficult for a child to operate this far due to mischief, and the risk is reduced. In this embodiment, the concave portion 171a of the closing plate 171 is configured to be effective in parallel with the connecting rod 110. However, when a burner that requires strong combustion at the time of ignition is used, the opening adjustment body 1 is used.
Where 70 is at that position, the recess 17 of the closing plate 171 is
It is better to form 1a.

Next, another embodiment will be described. Figure 9
In (a) of item 180, reference numeral 180 is a closing hanging plate as a closing means for limiting the operation of the connecting rod 110. Opening control body 1
Reference numeral 70 denotes a vertical movement portion 170a and a connection portion 170b connected to the gas cock, and the vertical movement portion 170a can move up and down at the joint. The closing hanging plate 180 has a hole portion through which the connecting rod 110 penetrates, and a sliding resistance portion 181 as a flexible sliding resistance means is provided in the lower portion of this hole portion. The operation will be described.
When the normal cooking device is not used, the vertical movement portion 170a of the opening degree adjuster 170 is lifted upward as shown in FIG. 9B, and the sliding resistance portion 181 prevents the connecting rod 110 from moving. . Therefore, the ignition / extinguishing operation body 102 cannot be pushed in. When the gas cock 149 is opened and used, as shown in FIG.
The sliding resistance portion 181 is separated from the connecting rod 110 by lowering the vertically moving portion 170a of FIG. 9B from the state of FIG. 9B.
As a result, the connecting rod 110 can be operated, the ignition / fire extinguishing operation body 102 can be pushed in, and the opening degree adjusting body 170 for adjusting the gas cock can also be operated. In this operation, the ignition / fire extinguishing body can be pushed in by pulling down the vertically moving portion 170a only when it is used, and the operation preventing function can be realized without adding a complicated mechanism.

Next, another embodiment will be described. FIG.
Reference numeral 0 (a) is a conventional ignition circuit, 190 is a battery as a power source, 191 is a power switch that opens and closes in conjunction with the ignition / extinguishing operation member 102, and 192 is an igniter. In this configuration, by pressing the ignition / extinguishing operation body 102, the power switch 191 is closed, power is supplied to the igniter 192, and an ignition spark is emitted. Since the normal ignition / extinguishing operation body 102 operates with a force that can be pushed even by a child, there is a possibility that operations such as mischief will frequently occur. In order to solve this problem, a power switch 191 and a battery 190 are provided as shown in FIG.
A second switch 193 is provided in series between the two. Therefore, if the second switch 193 is opened, even if the ignition / fire extinguishing operation body 102 is pushed, no current is supplied to the igniter 192 and no ignition spark is emitted, which is safe. Also, if the second switch 193 is installed on the operation panel unit 112, the child may learn the operation and may not be useful. For this reason, as shown in FIG. 9C, if the second switch 193 is installed in a place where children cannot reach physically, the second switch 193 will not be operated. In this embodiment, it is installed at the rear of the casing 101, but it may be difficult to operate because it operates across the burner unit 199. In this case, the upper surface 19 of the housing
In FIG. 4, the second switch 193 may be installed at a position apart from the operation panel unit 112.
