Note that the drive spring 48 has one end locked to the peripheral edge of the cover 55.

Then, an operation dial 52 is attached to the outer end of the operation shaft 37.

Further, a vibration sensing device 58 is provided on one side of the fixed tank 1 via a base 57.

This vibration sensing device 58 operates on the locking piece shaft 6 in response to the movement of the pendulum 59.

Further, a fire extinguishing lever 62 is provided in the interlocking process between the pendulum 59 and the locking piece 61.

Prior to fixing the burner basket 4 to the fixed tank 1, the operating shaft 37
, a return spring 51, a core holder 31, etc. are attached to the burner basket 4, and the above-mentioned connecting plate 16, upper and lower auxiliary guide plates 12, 13, guide plate 5, and drive circle are attached to the burner basket 4. When installing the burner basket 4 to the fixed tank 1 in this state, insert the slide pin 33 of the drive disk 29 into the slide pin insertion hole 33 of the core holder 31. When inserted, the pair of mounting brackets 4a installed oppositely on both sides of the burner basket 40 are overlapped with the pair of fixing brackets 1a installed oppositely on both sides of the fixed tank 10, and tightened with screws 65. .

Note that 4b is a base for mounting an ignition device (not shown).

In such a configuration, when the operating shaft 37 is rotated clockwise through the operating dial 52 during combustion use, the return spring 51 is also rotated clockwise together with the operating shaft 37, and the ratchet plate 46 also rotates clockwise in the vibration sensing device 58. The locking piece 61 rotates clockwise while resisting the spring pressure of a spring (not shown) and is prevented from reversing by the locking piece 61, and the spring 51 is gradually restored.

Further, the pinion 38 rotates clockwise together with the operating shaft 37, and the pinion 38 rotates the core holder 31 clockwise via the horizontal portion 34 of the rack 36 with which it engages, and rotates the drive disk 29 clockwise via the slide pin 33. let

As the drive disk 29 rotates clockwise, the drive shaft 20 is pushed by the small hole a in the long hole 30 of the drive disk 29.
The drive shaft 20 moves along the elongated holes 14, 15, and 28 of the auxiliary guide plates 12, 13 and the guide plate 5, thereby expanding the connecting plate 16 in the horizontal direction and moving the driven shaft of the finely movable end 1T. 21 is moved in the centrifugal direction along the small elongated holes 22, 23 and begins to open a passage for the wick 7 to move up and down.

Then, when the pinion 38 of the operation shaft 3T is located in the middle of the inclined portion 35 of the rack 36, the connecting plate 16
has finished opening completely, and the lamp wick 7, which had already started to rise at this stage, rises to the fixed position due to the engagement of the pinion 38 with the remaining part of the inclined part 35 in the rack 36, and at the same time, the drive shaft 20 moves through the elongated holes 14, 15, 28. Guided by this, the drive disk 29 moves from the small hole a to the long hole 30 in the long hole 30, and thereby the drive disk 29 rotates idly.

If combustion is used in this state and some kind of vibration exceeds a certain degree during combustion, the pendulum 59 in the vibration sensing device 58 will swing, and the locking piece 61 will move against the locking piece shaft 6.
0 as a fulcrum, and at the same time releases the lock from the ratchet plate 46, the reversing force stored in the return spring 51 causes the operating shaft 37 to rotate counterclockwise.

This counterclockwise rotation of the operating shaft 37 causes an operation in the reverse order of the operation during the above-mentioned combustion use, and the driving disk 2
The rotation transmitted to the elongated hole 30 idles in the elongated hole part of the elongated hole 30 and does not lower the lamp wick T, but moves the drive shaft 20 in the centripetal direction in the small hole part a of the elongated hole 30 and lowers the lamp wick 7. After this, the connecting plate 16 closes the passage of the lamp wick 7.

If you want to extinguish the fire manually, push down the fire extinguishing lever 62 against the spring pressure of a spring (not shown), rotate the locking piece 61 clockwise around the locking piece shaft 60, and close the ratchet plate. When the locking piece 61 is released from the locking member 46, the fire extinguishing action is performed through the same sequence as in the case of the operation of the seismic device 58 described above.

Note that when manually rotating the operation dial 52 to the left to adjust combustion or extinguish the fire, the operation shaft 37, this operation shaft 3
A retainer 53 integrated by a locking pin 49 of No. 7, and a cover 55 that is engaged with a protrusion 50 of the retainer 53 and has one end of the drive spring 48 secured to its peripheral edge are engaged with each other. In the stopped state, as the operating shaft 370 is rotated by the operating dial 52, it rotates to the left.

Also, when rotating the operation dial 52 clockwise during combustion, the spring holder 4 of the drive spring 48
7, the force overcomes the reversing force of the return spring 510 and acts to prevent counterclockwise rotation.

Next, the assembly configuration will be explained.

As mentioned above, when fixing the burner basket 4 to the fixed tank 1, the operating shaft 3 is attached to the fixed tank 1.

At the same time, insert the slide pin 33 of the fixed tank 1.
A pair of mounting brackets 4 installed oppositely on both sides of the burner basket 40 versus a pair of fixing brackets 1a installed oppositely on both sides of the burner basket 40.
A is made to overlap and then tightened and fixed with a screw 65.

In this case, as shown in FIG.
On the side, two slide pins 33 of the driving disk 29 are disposed vertically at opposite positions on a concentric circle on the driving disk 29, and each slide pin 33 is held in advance by holding the continuous plate 16 in an open state. In this state, the drive disk 290 is vertically disposed offset by a predetermined angle α in one direction of rotation with respect to the arrangement position of the pair of fittings 4a of the burner basket 4.

In addition, as shown in FIG. 2A, two slide pin insertion holes 32 of the lead holder 31 are formed on the fixed tank 1 side at opposing positions on a concentric circle in the lead holder 31, and each The slide pin insertion hole 32 is deviated by a predetermined angle β in the other direction of rotation of the lead holder 31 with respect to the mounting position of the pair of fixing fittings 1a of the fixed tank 1 when the return spring 51 has no stored force in advance. Provided.

In this state, as shown in FIG. 2B, for each slide pin insertion hole 32 of the core holder 31 on the fixed tank 1 side,
Insert each slide pin 33 of the drive disk 29 on the burner basket 4 side.

In this connected state, the mounting bracket 4a of the burner basket 4 is deviated by an angle (α+β) which is the sum of the above-mentioned deviation angle between the slide pin 33 and the slide pin insertion hole 32 with respect to the fixing bracket 1a of the fixed tank 1. in position.

Next, when the burner basket 4 is rotated in one direction (clockwise in FIG. 2B) relative to the fixed tank 1, the wick holder 31 is rotated in the same direction through the engagement between the slide pin 33 and the slide pin insertion hole 32. horizontal part 3 of the rack 36
4, the operating shaft 37 is rotated together with the pinion 38 in the direction of raising the lamp wick T, and the return spring 51
It acts to tighten the winding.

At the same time, due to the tightening resistance of the return spring 510, the drive disk 29, which has a lower rotational resistance, is rotated counterclockwise in FIG. The drive shaft 2 is rotated, thereby causing the drive shaft 2
0 is moved while being engaged with the small hole a of the elongated hole 30 of the driving disk 29, and the connecting plate 16 is brought into a closed state.

Further, along with the closing operation of the connecting plate 16, the core holder 31 is further rotated in the same direction through the engagement between the slide pin 33 and the slide pin insertion hole 32 as described above, and the horizontal portion of the rack 36 is rotated. 34, the operating shaft 37 is further rotated together with the pinion 38 in the direction of raising the lamp wick 1, and this causes the return spring 51 to store energy, that is, the return spring 51 acts to lower the lamp wick 7. Stockpile a certain amount of biasing force.

In this case, the pinion 38 is attached to the horizontal portion 3 of the rack 36.
4, the lifting action of the lamp wick 7 is not performed (1 degree).As shown in FIG. When the mounting bracket 4 is aligned, tighten it with the screw 65 to fix it.

By assembling in this manner, the connecting plate 16 is set in a closed state, and the return spring 51 is set in a state in which it stores a biasing force in the direction of lowering the core.

The deflection angle α of the slide guide 33 and the deflection angle β of the slide pin insertion hole 32 may be appropriately selected depending on the amount of opening/closing movement of the connecting plate 16 and the biasing force of the return spring 51.

According to the present invention, by rotating the operating shaft during combustion, the core holder is rotated via the pinion and rack,
The drive disk is rotated via the slide pin, actuating the drive shaft to open the connecting plate and raise the lamp wick.Also, when extinguishing the lamp, the biasing force of the return spring is stored when the lamp wick rises. The wick holder is rotated in the opposite direction, lowering the wick and closing the connecting plate.
When assembling the burner basket side to the fixed tank side, insert the slide pin of the drive disk equipped on the burner basket side into the slide pin insertion hole of the core holder equipped on the fixed tank side, and
In this state, by rotating the burner basket in one direction and fixing the burner basket to the fixed tank, the driving disk moves in one direction by the preset deflection angle of the slide pin, that is, in the direction that closes the connecting plate. At the same time, the wick holder is rotated slightly in the other direction by the preset deflection angle of the slide pin insertion hole, that is, in the direction of raising the wick, and this causes the wick to return. The spring is stored with a certain biasing force that acts to lower the wick, and therefore, in the assembled state, the return spring can reliably apply the biasing force for lowering the wick and closing the connecting plate. In addition, since the return spring and the connecting plate can be assembled in a natural state with zero reaction force during assembly, the assembly work can be easily performed and workability can be improved.

In addition, the slide pin is provided with a predetermined angle deviation to one side with respect to the fixed position of the burner basket, and the slide pin insertion hole is provided with a predetermined angle deviation to the other side with respect to the fixed position of the burner basket. The respective deflection angles can be easily set separately depending on the amount of opening/closing movement of the connecting plate and the biasing force of the return spring on the lead holder side, making it possible to design and manufacture easily and reliably.
