Description

DETAILED DESCRIPTION OF THE INVENTION <Technical Field> The present invention relates to a wick lifting device for a liquid fuel combustor such as a lever-operated kerosene stove.

<Prior Art> Among conventional kerosene stoves, there is no lever-operated kerosene stove that can be set in an emergency but cannot be set in a normal situation. For this reason, the normal setting can be made even though the emergency setting has not been completed, so in the event of an earthquake or the stove falling over, the emergency automatic fire extinguishing system will not operate.
There was a serious defect in which the wick would not lower (extinguish the fire) unless the extinguishing lever was operated manually.

<Purpose> Therefore, the present invention uses the same operating lever to perform emergency setting and normal use setting, and to prevent liquid fuel from being set (locked) during normal use until the emergency setting (lock) is completed. The present invention aims to provide a combustor wick lifting device.

<Example> Hereinafter, an example of the present invention will be described based on the drawings.

A bushing 2 is caulked into the hole 1a of the base plate 1, and the bushing 2 has a swing center hole 3a of the emergency actuation plate 3 and a swing of the core lifting plate 6 to which the adjustment plate 4 is pivotally connected by a stepped pin 5. A dynamic center hole 6a is attached so as to be swingable, and an E-ring 7 prevents them from coming off.
Further, an interlocking piece 3b is formed on the emergency actuation plate 3 for interlocking with the core elevating plate 6. A weight stand 8 constituting the emergency automatic fire extinguishing system A is fixed to the board 1 with eyelets 9, and a locking plate 10 is attached to the upper part of the board 1 with pins 11. A chain 13 is attached to the weight 12, and the chain 13 is passed through a hole in the weight stand 8, passes through a hole 10a at the tip of a locking plate 10, and is prevented from coming off by a chain stopper 14. A pipe shaft 15 is erected at the bottom of the substrate 1, an elevating body 16 is slidably fitted thereon, and the pipe shaft 15 is fixed to the substrate 1 from above with a pipe angle 17.
A knob 18a is press-fitted into the front part of an operating lever 18 protruding from the elevating body 16. Further, the rear convex portion 16a of the elevating body 16 is inserted into the slit portion 1b of the base plate 1 so that the operating lever 18 does not rotate.

The normal fire extinguishing lever 19 is swingably attached to the base plate 1 via a shaft 20, and the lower part 1 of the normal fire extinguishing lever 19
A fire extinguishing knob 21 is press-fitted into 9a. The fire extinguishing lever 19 usually has a small upper projection 1 with a cam function.
9b and a lower protrusion 19c. A locking pin 22 is caulked to the left end of the emergency actuation plate 3, and a locking pin 23 is attached to the right end of the core elevating plate 6. In addition, an emergency spring 24 is installed between the emergency operation plate 3 and the lower part of the base plate 1, and an emergency spring 24 is installed between the core lifting plate 6 and the base plate 1
A descending spring 25 is stretched between the lower portions of each of the two, and urges each of them in the counterclockwise direction.

An oval hole 4a at the right end of the adjusting plate 4 incorporated in the core elevating plate 6 engages with a lower front convex portion 16b of the elevating body 16. A fire extinguishing spring 26 is stretched between a normal fire extinguishing lever 19 pivotally connected to the lower part of the board 1 by a shaft 20 and the lower part of the board 1, and urges the normal fire extinguishing lever 19 in the direction of the board 1. The linking plate 28 on which the linking pin 27 is caulked is fixed with a screw 28a to a core lifting shaft 29 which is swingably fitted into the bushing 2, and is moved from the core to the holder by rotation of the lead lifting shaft 29. The core assembly 30 is raised and lowered.
The linking pin 27 engages with the center hole 4b of the adjustment plate 4,
Furthermore, it is inserted into the hole 6b of the core lifting plate 6.

As mentioned above, the wick lifting/lowering device has a wick lifting plate 6 which swings to the wick raising side and locks by the setting operation during normal use, and is unlocked and swings to the wick lowering side by the extinguishing operation during normal fire extinguishing. Then, the lowering spring 25, which biases the core lifting plate 6 toward the core lowering side, is unlocked by the operation of the emergency automatic fire extinguishing device A, and swings to the core lowering side, and at the same time, the core lifting plate 6 is moved to the core lowering side. It is provided with an emergency actuation plate 3 that is interlocked with each other, and an emergency spring 24 that biases the emergency actuation plate 3 toward the core downward direction.

Next, to explain the operation, move the operating knob 18a, that is, the operating lever 18 downwards to the emergency spring 2.
4. When pushed against the lowering spring 25, the elevating body 16 integrated with the operating lever 18 moves downward using the pipe shaft 15 as a guide, and the elevating body 16 and the adjustment plate 4 are engaged. , these move downward, and at the same time, the emergency actuation plate 3 engaged by the interlocking piece 3b also swings clockwise, and the linking plate 28, to which the linking pin 27 is crimped, also swings clockwise. , the core lifting shaft 29 and the core assembly 30 connected thereto also begin to move. The lock pin 22 crimped on the emergency actuation plate 3 is inserted into the guide hole 10b of the locking plate 10.
The locking pin 23 of the core lifting plate 6 is locked to the upper protrusion 19b and set.
As shown in Fig. 4, the emergency operation plate 3 and the wick lifting plate 6 are set, and the wick assembly 30 is raised to prepare for combustion (set).
is completed.

When the fire extinguishing knob 21 is pushed downward, the normal fire extinguishing lever 19 integrated therewith moves toward you, and the locking pin 23 of the wick elevating plate 6 is disengaged from the upper protrusion 19b and engaged with the wick elevating plate 6. By means of the linking pin 27, the linking plate 28, the core elevating shaft 29, the core assembly 30, the adjustment plate 4 incorporated in the core elevating plate 6, the elevating body 16 engaged therewith, the knob 18a, etc. are all lowered by the lowering spring 25. Switches to extinguished state or unlocked state by force. In this case, the emergency actuation plate 3 does not come off and remains locked. In the next operation, only the core lifting plate 6 is slid, so that only the force of the lowering spring 25 is applied to the operating lever 18, and the operation can be performed easily.

In the event of an earthquake or fall, the weight 12 falls down, the chain 13 is pulled up, and the locking plate 10, which is stopped by the chain stopper 14, moves counterclockwise, and the locking pin 22, which is crimped on the emergency activation plate 3, moves to the locking part. 10c, the emergency activation plate 3 moves downward in a counterclockwise direction by the force of the emergency spring 24, and the right end shoulder 3c of the emergency activation plate 3 moves upward, causing the lower protrusion 19c of the normal extinguishing lever 19 to move toward the front. By pushing the fire extinguishing knob 21 downward, the locking pin 23 of the core lifting plate 6 is removed from the upper protrusion 19b of the normal fire extinguishing lever 19, and the following movement of the parts is the same as normal extinguishing. . In this case, since the forces of the emergency spring 24 and the lowering spring 25 are applied, the core assembly 3
The descending force at 0 becomes stronger and descends rapidly.

Next, mainly based on FIGS. 3 and 4, there is provided an operating lever 18 that can perform both an emergency setting operation for the emergency automatic fire extinguishing system A and a normal use setting operation for the core assembly 30, and a normal fire extinguishing operation. The structure and operation of the normal fire extinguishing lever 19, which is possible and which allows the normal use setting to be completed only after the emergency setting is completed when the operating lever 18 is set, will be explained.

Figure 3a shows the normal fire extinguishing lever 1 in the unlocked state.
9. A side view showing the locking pin 23 and the right end shoulder 3c of the emergency actuation plate 3; FIG. , same c shows that the locking pin 23 is in a lockable state, but the normal fire extinguishing lever 19 and the locking pin 2 cannot be locked because the lower protrusion 19c of the normal fire extinguishing lever 19 hits the right end shoulder 3c.
3. Side view of the right end shoulder 3c, d shows the normal extinguishing lever 19, the locking pin 23, and the right end shoulder in the fully set (locked) state when the locking pin 22 is locked to the locking plate 10 as shown in FIG. 3c is a side view.

When the lifting body 16 is pushed down in the state shown in FIG. 1 and the core lifting plate 6 is moved clockwise in the set direction, its left end hits the interlocking piece 3b of the emergency actuation plate 3 and both start moving at the same time. As shown in Figure 3 a,
Normally, the fire extinguishing lever 19 is pushed forward by the locking pin 23 at the right end of the core elevating plate 6, so the emergency activation plate 3 normally moves without touching the fire extinguishing lever 19. After passing through the state shown in Figure 3b, the lock pin 22
is in a position where it can be locked, but as shown in FIG.
When the emergency activation plate 3 is in a position where it cannot be locked, the right shoulder 3c at the right end of the emergency actuation plate 3 is below the lower protrusion 19c of the normal fire extinguishing lever 19, and it is centered on the upper protrusion 19b of the normal fire extinguishing lever 19. The locking pin 23 of the elevating plate 6 engages and locks. At the point where the locking plate 10 and the locking pin 22 are locked, the upper protrusion 19b of the fire extinguishing lever 19 and the locking pin 23 are normally connected as shown in Fig. 3c.
As shown, the lock point has passed. Therefore, when you stop pressing the operating lever 18, the core lifting plate 6 that has turned too far clockwise is pulled back by the lowering spring 25, and the upper protrusion 19 of the fire extinguishing lever 19 is normally pulled back.
b The locking pin 23 of the core lifting plate 6 returns to the lower edge,
As shown in FIG. 4, a gap C is created between the lower edge of the interlocking piece 3b of the emergency actuation plate 3 and the upper edge of the core lifting plate 6. This gap C
is important during emergency firefighting (earthquakes, falls).

Next, when the weight 12 is activated due to an earthquake, fall, etc., when the weight 12 falls, the locking plate 10 rotates counterclockwise, and the lock pin 22 crimped to the emergency activation plate 3 comes off, causing the emergency activation plate 3 to only begins to move.
This is because a gap C is provided between the above-mentioned emergency actuation plate 3 and the core lifting plate 6, and the movement of the right end shoulder 3c of the emergency actuation plate 3 by the amount of the gap C causes the normal extinguishing lever 1 to move.
As the lower protrusion 19c of 9 is strongly pushed, the normal fire extinguishing lever 19 moves in the front direction, the locking pin 23 built into the wick lifting plate 6 comes off, and the wick lifting plate 6 also releases its lowering spring in the same way as the emergency activation plate 3. 25, the core assembly 30 is rotated counterclockwise by the force of the emergency spring 24 and lowered via the linking plate 28 and the core lifting/lowering shaft 29.

For normal fire extinguishing, when the fire extinguishing knob 21 is pressed, the normal fire extinguishing lever 19 moves in the front direction, removes the locking pin 23 built into the core lifting plate 6, and lowers the lowering spring 2.
It is rotated counterclockwise by the force of 5, and the core is lowered. In this case, the emergency actuation plate 3 does not move. The locking pin 22 and the locking plate 10 are locked, and normally remain in that state regardless of when the fire is extinguished. Therefore, the next core raising operation can be carried out easily since only the force of the lowering spring 25 connected to the core lifting plate 6 is applied.

<Effects> As is clear from the above description, the present invention has a wick lifting shaft that rotates to move the fuel wick up and down, a wick lifting plate that swings to rotate the wick lifting shaft, and a wick lifting plate that swings to rotate the wick lifting shaft. A lowering spring that biases the core lifting plate toward the core lowering side, an operating lever for swinging the core lifting plate toward the core lifting side, and a set completion posture and core lifting/lowering that locks the core lifting plate in the core lifting position. A normal fire extinguishing lever that can swing freely to switch to a release position that releases the locking of the plate, a fire extinguishing spring that urges the normal fire extinguishing lever toward the set completion side, and a locking part of the emergency automatic fire extinguishing system that engages. an emergency actuation plate that swings between a set position in which the core is moved and a release position in which the core is released from the locking portion; an emergency spring that biases the emergency actuation plate in the core lowering side; In conjunction with the swinging, the emergency actuating plate is locked in the locking part of the emergency automatic fire extinguishing system at the wick up position, and when the emergency actuating plate swings to the wick lowering side due to the activation of the emergency automatic fire extinguishing system, the wick lifting plate is an interlocking piece formed on the emergency activation plate so as to swing in conjunction with the lowering side of the core, the end of the emergency activation plate including:
It is extended to a position where it engages with the normal fire extinguishing lever so as to prevent the core lifting plate from engaging with the normal fire extinguishing lever before the emergency setting is completed.

Therefore, according to the invention, the interlocking piece allows
By operating the control lever, the core lift plate and emergency activation plate are linked, allowing the same control lever to be used for both emergency and normal use settings.
At this time, the end of the emergency activation plate is extended to a position where it engages with the normal fire extinguishing lever so as to prevent the core lifting plate from engaging the normal fire extinguishing lever before the emergency setting is completed. Since the emergency automatic fire extinguishing system cannot be set for normal use until the emergency setting is completed, excellent effects can be expected, such as being able to operate the emergency automatic fire extinguishing system at all times.
