Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a wick lifting and lowering device with a fire extinguishing function in a liquid fuel combustor such as an upper and lower wick oil combustor.

<Prior art> In general, a wick lifting device has a vibration sensing mechanism that detects vibrations caused by an earthquake, immediately lowers the wick, and automatically extinguishes the fire, and a mechanism that automatically extinguishes the wick by lowering an operating lever. It has a mechanism that raises the wick in conjunction with this, and a mechanism that lowers the wick immediately by operating the extinguishing lever.

In the conventional wick lifting device, as shown in FIG.
A wick adjustment shaft 107 is disposed perpendicular to the combustion tank 101, and the front end of the wick adjustment shaft 107 protrudes from the front surface of the combustion tank 101. In addition, the combustion tank 101
Parts such as an operating lever 147 and a core lifting member 132 are arranged parallel to the front surface 101A.

A core adjustment shaft 107 is connected to the left end of the operating lever 147, and an operating knob 147A in a direction perpendicular thereto is connected to the right end of the operating lever 147.
is provided protrudingly so that the user can easily pick the operation knob 147A.

<Problems to be Solved by the Invention> However, since the knob 147A is perpendicular to the operating lever 147 in this way, a force is generated to pry the operating lever 147 due to the operating force when the lead is raised.
Therefore, there is a drawback that the operating lever 147 cannot be operated smoothly.

In view of the above, an object of the present invention is to provide a core lifting device that can smoothly operate the operating lever without causing any force that forces the operating lever when the lead is raised, and can also shorten the operating stroke. .

<Means for Solving the Problems> As shown in FIGS. 1, 2, and 4a, the means for solving the problems according to the present invention is such that a lead adjustment shaft 7 is installed laterally in the left-right direction, and the lead adjustment shaft 7 is attached to a lead holder. An operating knob 47A is fixed to the tip of a rotatable operating lever 47 which is rotatably supported on the combustion tank 1 in front of the left-right horizontal line CL passing through the center of 4, and which performs wick raising operation and wick fine adjustment. A lever 47 is disposed in a direction substantially perpendicular to the core adjustment shaft 7, and an interlocking mechanism is provided that rotates the core adjustment shaft 7 as the operating lever 47 rotates, and one side of the interlocking mechanism is connected to the operating lever. 47, and the other side is fixed to one end of the wick adjustment shaft 7, and rotates to the extinguishing set position 32B as the operating lever 47 is operated to raise the wick, and finely adjusts the wick of the interlocking mechanism at the extinguishing set position 32B. A lead elevating member 32 that allows movement only within a range is provided, and a locking means is provided for locking the lead elevating member 32 at the fire extinguishing set position 32B, so that the center of rotation of the operating lever 47 is the center of the lead holder 4. horizontal horizontal line passing through
A lead lifting arm 8 is movably connected to the other end of the lead adjusting shaft 7, which is disposed in front of the CL, and is substantially perpendicular to the lead adjusting shaft 7, so that the lead holder 4 is moved up and down by the rotation of the lead lifting arm 8. The core lifting arm 8
and the lead holder 4 are movably connected.

<Operation> In the problem solving means described above, in order to raise the lead 5, the lead operating lever 47 is pushed down. Then, the operation lever 47 rotates downward, and the kinetic force is applied to the movement member 41 connected to the operation lever 47 and the fine adjustment member 3 connected to the movement member 41, as shown in FIG.
9, and a connecting member 52 that moves on the fine adjustment member 39 and is fixed to the core adjustment shaft 7 (these constitute a movement mechanism)
, the core adjustment shaft 7 rotates, and the core lifting arm 8
rotates, and the lead 5 connected to the lead holder 4 is raised and set.

Further, as the fine adjustment member 39 moves, the fine adjustment member 39 hits the bent portion 56 of the core elevating member 32, and the core elevating member 32 rotates to switch from the extinguishing release position to the extinguishing set position. In the extinguishing set position of the wick elevating member 32, the pin 33 of the wick elevating member 32 is connected to the extinguishing lever 4.
4 (these constitute a locking means).

When finely adjusting the core 5, the operating lever 47 is pulled up by a desired amount. Then, the operating lever 47,
The movement member 41 and fine adjustment member 39 move in the opposite direction to the lifting operation, but since the core elevating member 32 is locked at the extinguishing set position, the extinguishing set position is maintained, and the fine adjustment member 39 bends the core elevating member 32 vertically. Rotation is allowed only within the portions 56 and 59, so that movement is transmitted from the connecting member 52 connected to the fine adjustment member 39 to the core adjustment shaft 7, and fine adjustment of the core 5 is performed.

This operating lever 47 is connected to the front surface 1 of the combustion tank 1.
Since it is almost perpendicular to A, the operation knob 47
A can be directly fixed to the front end of the control lever 47, so that the control lever 47 can be rotated smoothly without any force exerted on the control lever 47 by the operating force when raising the core and finely adjusting the core.

Further, the wick adjustment shaft 7 is rotatably supported by the combustion tank 1 in front of the horizontal line CL in the left-right direction passing through the center of the wick holder 4, and a wick lifting arm 8 is interposed between the wick holder 4 and the wick adjustment shaft 7. Since the center of rotation of the operating lever 47 is located in front of the horizontal line CL passing through the center of the lead holder 4, even if the vertical stroke of the knob 47A is short, the increased width of the lead lifting arm 8 allows the lead holder 4 to move forward. can be raised and lowered sufficiently. Therefore, the operating lever 47 is also shortened, and since the operating lever 47 is also used for core raising operation and core fine adjustment operation, each component can be made smaller, and the entire core lifting device can be made smaller and cheaper. .

Further, since the wick adjustment shaft 7 is parallel to the front surface 1A of the combustion tank 1, the position of the operating lever 47 can be arbitrarily changed in the left-right direction by simply changing its length in the left-right direction.

[motion] Next, a series of operations of the core lifting device will be explained.

(Core raising operation) First, when the operating lever 47 is pushed down,
The operating lever 47 rotates counterclockwise around the sixth stepped pin 51, and switches from the below-core position 47A in FIG. 3a to the above-core position 47B in FIG. 3b.

At this time, the front part of the operating lever 47 is pivotally supported by the fifth stepped pin 48 to the interlocking member 41 through the oval-shaped hole 49 of the base plate 17, so that the interlocking member 41 is
It moves up and down within the range of the oval-shaped hole 49 of the substrate 17.

Then, the fine adjustment member 3 connected to the interlocking member 41
9 is pivotally supported by the core lifting member 32, so the second
It rotates counterclockwise around the stepped pin 40. Then, the lower edge 55 of the front end of the fine preparation 39 is connected to the core lifting member 3.
The core lifting member 3 hits the bent portion 56 at the lower front end of the
2 rotates counterclockwise around the main bearing 24 from the extinguishing release position 32A to the extinguishing set position 32.
Switch to B.

Then, the bending portions 5 at the upper and lower central portions of the fine adjustment material 39
A connecting member 52 fixed with a female screw 13 to the tip of the core adjusting shaft 7 inserted into the core adjusting shaft 7 is connected to the core lifting member 32.
It rotates counterclockwise around the core adjustment shaft 7 in accordance with the rotation of. Along with this, the lead lifting arm 8 fastened to the lead adjustment shaft 7 rotates counterclockwise, and the lead 5 connected to the lead holder 4 via the first pin 9 at the tip rises and is set. state.

Furthermore, when the core elevating member 32 rotates counterclockwise, the protrusion 57 at the rear upper part hits the back surface of the bent portion 58 at the rear upper part of the emergency actuating member 26, and the emergency actuating member 26 moves counterclockwise around the main bearing 24. Rotate in the direction. Then, the third pin 28 at the rear end of the emergency actuation member 26 moves upward through the hole 23 at the lower end of the locking member 20 through the oval-shaped hole 30 in the base plate 17, and locks. It moves upward from the section 23a.

The locking member 20 is rotatably supported by the first stepped pin 21, but because it is heavy at the front, it always tries to rotate counterclockwise (when viewed from the side). Therefore, if you slightly loosen the pressure on the operating lever 47, the previous movement will reverse.
The third pin 28 is slightly lowered and caught on the locking portion 23a.

The emergency actuation member 26 is provided with an emergency actuation spring 31 that is always biased clockwise.
After the emergency actuation member 26 rotates counterclockwise, the third
Since the pin 28 is locked to the locking portion 23a, the emergency actuation member 26 moves from the release position 26A to the consumption position 26B.
The spring 31 is set in an expanded state.

Further, the hole 23 of the locking member 20 is an inverted dog-shaped hole such that the lower side is in front of the locking part 23, and the hook 19 of the weight 16 is connected to the third pin 28.
Since the link 19 is attached at the lowest position of the pull-out hole 23, a gap is created between the attachment part of the link 19 and the locking material 20 when the third pin 28 is at the position of the locking part 23a. There is. The weight 16 is set in an inverted state, so if it falls due to an earthquake or impact, it will
The locking member 20 is pulled clockwise by the hook 19, and the third pin 28 in the locking portion 23a comes off and moves downward by the force of the emergency actuation spring 31. When the third pin 28 moves downward, the weight 16 is automatically returned to the inverted state.

Also, the second pin 2 at the front end of the emergency actuation member 26
7 moves from above to below through the oval-shaped cutout hole 29 in the base plate 17 and fits into the opening 44d formed in the extinguishing lever 44. At this time, the fire extinguishing lever 44 is lowered while the fourth pin 33 at the front end of the core elevating member 32 slides from above to below on the sliding part 44b of the consumption lever 44, but the sliding part 44b is formed in a dogleg shape. Therefore, it rotates counterclockwise around the fourth stepped pin 45 and returns to its original position. Therefore, the second pin 27 of the emergency actuation member 26 is connected to the fire extinguishing lever 44.
Smoothly enters the opening 44d located at. , the fourth pin 33 of the core lifting member 32 is connected to the fire extinguishing lever 4
After sliding down the sliding portion 44b of No. 4, it is locked by the locking portion 44c at the lower end. The core elevating member 32 is provided with a core elevating spring 36 that is always biased clockwise, but after the core elevating member 32 rotates counterclockwise, the fourth pin 33 engages with the locking portion 44c. Therefore, the core lifting spring 36 is set in an extended state.

The third pin 28 at the rear end of the emergency actuation member 26 is locked to the locking portion 23a of the locking member 20, and a little later, the fourth pin 33 at the front end of the core elevating member 32 is locked to the locking portion of the fire extinguishing lever 44. 44c, so the protrusion 57 on the back upper part of the core elevating member 32,
The emergency actuation member 26 is set with a slight gap between the bent portion 58.

The fire extinguishing lever spring 46 is provided so that the fourth pin 33 of the core elevating member 32 can be easily engaged with the engagement portion 44c.

(Fine adjustment operation of the lead) Fine adjustment of the lead is performed by pulling up the operating lever 47 by a desired amount from the state in which the lead has been set by the previous operation.

Then, the operating lever 47, interlocking member 41, and fine adjustment member 39 move in the opposite direction, but since the wick elevating member 32 and the emergency actuating member 26 are respectively locked, they maintain the locked state, that is, the extinguishing set positions 32B and 26B. .

The fine adjustment material 39 has a second stepped pin 4 on the core elevating material 32.
0, it rotates clockwise when the operating lever 47 is pulled up, but the bent part 53 at the top hits the back side of the bent part 59 at the front upper part of the core lifting member 32. Stop. Fine adjustment material 39
The connecting member 52 connected to the fine adjustment member 39 rotates within the upper and lower bent portions 56 and 59 of the core elevating member 32.
The movement is transmitted from the center to the core adjustment shaft 7, and fine adjustment of the core is performed.

(Normal fire extinguishing operation) In the case of normal fire extinguishing, when the fire extinguishing lever 44 to which the fire extinguishing knob (not shown) is attached is pushed counterclockwise, the wick is locked in the locking part 44c and is in the fire extinguishing set position 32B. The fourth pin 33 of the elevating member 32 comes off from the locking portion 44c. Then, the core elevating spring 36 rotates the core elevating member 32 clockwise, and the lower end 60 of the inner end hits the lower surface of the base plate 17 and stops at the extinguishing release position 32A. At the same time, fine adjustment material 3
9. The interlocking member 41 and the operating lever 47 operate in the opposite direction, returning to the original state.

Further, the connecting member 52, the wick adjustment shaft 7, the wick lifting arm 8, and the wick 5, which are linked to the fine adjustment member 39, similarly operate in the opposite direction, and the wick 5 descends to extinguish the fire.

The second pin 27 of the emergency actuation member 26 is
Since the extinguishing lever 44 is stopped near the upper edge 61 of the opening 44d, even if the extinguishing lever 44 is pushed, the extinguishing lever 44 rotates counterclockwise, so there is no contact between the second pin 27 and the extinguishing lever 44. Therefore, the third pin 28 of the emergency actuation member 26 remains locked to the locking portion 23a of the locking member 20.

When the operating lever 47 is pushed down again from this state, the same core raising operation as described above is performed.

(Operation for emergency fire extinguishing) Next, in the case of emergency fire extinguishing, when the weight 16 set in an inverted state as described above falls down due to an earthquake or impact, the locking member 20 rotates clockwise, and the locking member 20 rotates clockwise. The third pin 28 of the emergency actuation member 26, which is locked to the emergency actuation member 23a, comes off, and the emergency actuation member 26 begins to rotate clockwise by the force of the emergency actuation spring 31.

At this time, since no force is applied to the core lifting member 32 to release the fourth pin 33, the locked state is maintained.
Since the locking part 44c of the fire extinguishing lever 44 is locked with a slight deviation, the emergency actuation member 26 operates only by the gap between the protrusion 57 of the core elevating member 32 and the bent portion 58 of the emergency actuation member 26. The second pin 27 rotates clockwise and hits the upper edge 61 of the opening 44d of the fire extinguishing lever 44, causing the fire extinguishing lever 44 to rotate counterclockwise and the fourth pin 33 is locked to the lower locking part 44c. is removed, the core lifting member 32 and the emergency actuating member 26 are rotated clockwise by the forces of the core lifting spring 36 and the emergency actuating spring 31, respectively, and the core is lowered by a series of operations.

(Summary of the present invention) In the above embodiment, to summarize the technical idea of the present invention, as shown in FIG. The wick adjustment shaft 7 is rotatably supported in the combustion tank 1 on the front side of the horizontal line CL in the left-right direction passing through the center of the cylindrical wick holder 4, and an operating lever 47 for performing a wick raising operation and a wick fine adjustment operation is provided. , is interlockingly connected to one end of the core adjustment shaft 7 in a direction substantially orthogonal thereto, indirectly or directly without intervening the interlocking member 41, the fine adjustment member 39, the connecting member 52, etc.; A lead lifting arm 8 that is substantially orthogonal to the other end of the lead adjusting shaft 7 is interlocked with the lead lifting arm 8 and the lead holder 4 so that the lead lifting arm 8 and the lead holder 4 are moved up and down by the rotation of the lead lifting arm 8. are linked together.

That is, in this embodiment, since the operating lever 47 is substantially perpendicular to the front surface 1A of the combustion tank 1, the operating knob 47A can be directly fixed to the front end of the operating lever 47, so that when the wick is raised, Since no force is generated to pry the operating lever 47 due to the operating force, the operating lever 47 can be rotated smoothly.

The wick adjustment shaft 7 is rotatably supported by the combustion tank 1 in front of the horizontal line CL in the left-right direction passing through the center of the wick holder 4, and a wick lifting arm 8 is interposed between the wick holder 4 and the wick adjustment shaft 7. Therefore, even if the vertical stroke of the knob 47A is short, the lead holder 4 can be raised and lowered by a sufficient amount due to the increased width of the lead lifting arm 8. Therefore, the operating lever 47 can also be short, and moreover, the operating lever 47 can be used for the lead raising operation. Since it is used both for the purpose of operation and fine adjustment of the core, each component can be made smaller, and the entire core lifting/lowering device can be made smaller and cheaper.

Further, since the wick adjustment shaft 7 is parallel to the front surface 1A of the combustion tank 1, the position of the operating lever 47 can be changed in the left-right direction by simply changing its length in the left-right direction.

[Proposed example] If the lead adjustment shaft 7 is arranged on the horizontal line CL passing through the center of the lead holder 4 (or on the back side of it) as in the proposed example shown in Fig. 5, the operating lever 47 etc. At the same time as each part became larger, the knob 47
Although the vertical stroke of A also needs to be long, the present invention does not have these drawbacks.

[Second Embodiment] Furthermore, the present invention is not limited to the above-mentioned first embodiment. In the present invention, for example, as in the second embodiment shown in FIG. 4b, the core lifting arm 8 is It may be formed into a U-shape in plan view, and the pins 9 at both ends thereof may be configured to engage with the elongated holes of the lead holder 4.

<Effects of the Invention> As is clear from the above description, according to the present invention, since the operating lever is arranged in the front-rear direction, the operating knob can be directly fixed to the front end of the operating lever. Since no force is generated to pry the operating lever, the operating lever can be rotated smoothly.

In addition, the wick adjustment shaft is rotatably supported on the combustion tank in front of the horizontal horizontal line passing through the center of the wick holder, and a wick lifting arm is interposed between the wick holder and the wick adjustment shaft, and the rotation center of the operating lever is is located in front of the horizontal horizontal line passing through the center of the lead holder, so even if the operating stroke of the operating lever is short, the lead lifting arm can raise and lower the lead holder by a sufficient amount, and therefore the operating lever is also short. Moreover, since the operating lever is used for both the core raising operation and the core fine adjustment operation, each component can be made smaller, and the entire core lifting device can be made smaller and cheaper, which is an excellent effect.
