After inserting the conical end portion 7a and the male threaded portion 7b at the tip, the female screw 13 is tightened to the male threaded portion 7b at the tip to fix the connecting member 52 and the core adjustment shaft 7. Further, the front F-shaped interlocking hole 52c is fitted with the interlocking pin 53 at the center of the fine adjustment member 39.

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

First, when the operating lever 47 is pushed down, it rotates counterclockwise around the sixth stepped pin 51 and cuts from the below-core position 47A in FIG. 3a to the above-core position 47B in FIG. 3b. Change. At this time, the front part of the operating lever 47 is pivotally supported by the fifth step pin 48 to the interlocking member 41 through the oval-shaped hole 49 of the board 17, so the interlocking member 41 is supported by the oval-shaped hole 49 of the board 17. Hole 4
It goes up and down within the range of 9. Since the fine adjustment member 39 connected to the interlocking member 41 is pivotally supported by the core elevating member 32, it rotates counterclockwise around the second stepped pin 40, but the lower edge 55 of the front end of the fine adjustment member 39 Lifting material 3
The core lifting member 32 hits the bent portion 56 at the lower front end of the
rotates counterclockwise around the main bearing 24,
Switching is made from the extinguishing release position 32A to the extinguishing set position 32B. When the core elevating member 32 rotates counterclockwise in this manner, 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 rotates counterclockwise around the main bearing 24. Rotate to. Located at the far end of the emergency actuation member 26, the board 1
The third pin 28 passes through the hole 23 at the lower end of the locking member 20 through the oval-shaped hole 30 of No. 7.
The hole 23 of the locking member 20 is moved from the bottom to the top, and the locking member 20 is moved upward from the locking portion 23a. Locking material 2
0 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 and the third pin 28 will move in the opposite direction.
is slightly lowered and caught on the locking part 23a. The emergency actuation member 26 is provided with an emergency actuation spring 31 that is always biased clockwise, but after the emergency actuation member 26 rotates counterclockwise, the third pin 2
8 is locked to the locking portion 23a, the emergency operating member 26 is switched from the release position 26A to the extinguishing position 26B, and the spring 31 is set in an expanded state. Further, the hole 23 of the locking member 20 is an inverted dog-shaped hole with the lower side being in front of the locking part 23, and the hook 19 of the weight 16 and the third pin 28 are inserted into the hole 23. Since the chain 19 is attached at the lowest position, the third pin 28 is attached to the locking part 23.
At position a, there is a gap between the attachment portion of the link 19 and the locking member 20. Since the weight 16 is set in an inverted state, if it falls down due to an earthquake or shock, the locking member 20 will be pulled clockwise by the chain 19, and the third pin 28 in the locking portion 23a will come off. It 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, a second pin 27 at the front end of the emergency actuation member 26
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 the fourth swage crimped to the front end of the core elevating member 32.
The pin 33 descends while sliding the sliding part 44b of the extinguishing lever 44 from above to below, but the sliding part 44
Since b is formed in a dogleg shape, it rotates counterclockwise around the fourth stepped pin 45 and returns to its original position.
Therefore, the second pin 27 is connected to the fire extinguishing lever 44.
Smoothly enters the opening 44d located at. The fourth pin 33 of the core elevating member 32 slides on the sliding part 44b of the fire extinguishing lever 44 and descends, and then the fourth pin 33 moves down to the locking part 4 at the lower end.
4c. 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. Third pin 28 at the rear end of the emergency actuation member 26
is locked to the locking part 23a of the locking member 20, and after a short delay, the fourth pin 33 at the front end of the wick lifting member 32 is locked to the locking part 44c of the fire extinguishing lever 44. Therefore, the protrusion 57 at the rear upper part of the core elevating member 32 and the bent portion 58 of the emergency actuating member 26 are set with a slight gap between them.

The connecting member 52 , which is fitted into the interlocking pin 53 in the center of the fine adjustment member 39 and fixed to the tip of the core adjustment shaft 7 with a female screw 13 , rotates around the core adjustment shaft 7 in accordance with the rotation of the core lifting member 32 . Rotate clockwise. Accordingly, the lead lifting arm 8 fastened to the lead adjustment shaft 7 rotates counterclockwise, and the lead 5 connected to the lead holder 4 rises through the first pin 9 at the tip, returning to the set state. Become. 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 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, as shown in FIG. 3c. 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. . Fine adjustment material 3
9 is rotatably supported on the core elevating member 32 by a second stepped pin 40, so that it rotates clockwise, but as this rotation occurs, the interlocking pin 53 moves into the F-shaped interlocking hole 52c of the connecting member 52. Since it is fitted to the inside of this F-shaped interlocking hole 52c, move it to the back side,
Reach the mountain part of the letter. Between this, the F-shaped interlocking hole 5
A rotational force is applied to the connecting member 52 via the peripheral wall 2c, and movement is transmitted from the connecting member 52 to the core adjustment shaft 7, thereby performing fine adjustment of the core.

In case of an emergency, if the operating lever 47 is further pulled up to the upper limit as shown in FIG. Since the adjustment shaft 7 rotates,
The wick 5 descends to the lower limit and extinguishes the fire.

Next, the extinguishing operation when the operating lever 47 is in the states shown in FIGS. 3b and 3c will be described.

In the case of normal fire extinguishing, when the fire extinguishing lever 44 to which a fire extinguishing knob (not shown) is attached is pushed counterclockwise, the first part of the wick lifting member 32, which is locked by the locking part 44c and located at the fire extinguishing set position 32B, is pressed in the counterclockwise direction. 4 pin 33 is removed, and the core lifting member 32 is moved by the core lifting spring 36.
rotates clockwise, and the rear end lower edge 60 hits the lower surface of the board 17 and stops at the extinguishing release position 32A. At the same time, the fine adjustment member 39, interlocking member 41, and operating lever 47 operate in the opposite direction, returning to their original states. Also, a connecting member 52 interlocked with the fine adjustment member 39, a core adjustment shaft 7,
The core lifting arm 8 and the core 5 operate in the same manner in reverse, and the core 5
descends and extinguishes the fire. The second pin 27 of the emergency activation member 26 is connected to the opening 44 of the extinguishing lever 44 when set.
Since the extinguishing lever 44 is stopped near the upper edge 61 of d, the lever rotates counterclockwise even if the extinguishing lever 44 is pushed, 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.

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 shock, the locking member 20 rotates clockwise and is locked to the locking portion 23a. The third pin 28 of the emergency actuation member 26 is removed, and the emergency actuation member 26 begins to rotate clockwise by the force of the emergency actuation spring 31. At this time, no force is applied to the core lifting member 32 to disengage the fourth pin 33, so the locked state is maintained, but as described above, the locking portion 23a of the locking member 20 is
Since the locking part 44c of the fire extinguishing lever 44 is locked with a slight deviation, the emergency actuation member 2 only covers the gap between the protrusion 57 of the core elevating member 32 and the bent portion 58 of the emergency actuation member 26.
6 does not operate, but the second pin 27 rotates clockwise, and the upper edge 6 of the opening 44d of the extinguishing lever 44
1, the fire extinguishing lever 44 is rotated counterclockwise, and the fourth
Remove the pin 33 and remove the core lifting member 32 and the emergency actuating member 2.
6 is rotated clockwise by the force of the core lifting spring 36 and the emergency actuation spring 31, respectively, and the core is lowered by a series of operations.

In the above embodiment, the technical idea of the present invention can be summarized as follows: As shown in FIG. 32B also includes a wick elevating member 32 that switches to the extinguishing release position 32A when the wick is lowered, and a wick adjusting shaft 7 that raises and lowers the wick by rotation.
A fine adjustment interlocking mechanism is provided between the core adjustment shaft 7 and the operating lever 47, and includes an interlocking pin 53 of the fine adjustment member 39 and an F-shaped interlocking hole 52c of the connecting member 52. is configured to transmit the wick downward movement of the operating lever 47 to the wick adjustment shaft 7 until the wick can be extinguished when the wick lifting member 32 is in the extinguishing set position 32B.

That is, in this embodiment, since the interlocking hole 52c of the connecting member 52 is long, it allows the interlocking pin 53 to move a large distance, and therefore the operation lever 47 and the core adjustment shaft 7
This allows the wick to move downward to the extinguishing position, expanding the range of fine adjustment of the fine adjustment interlocking mechanism that finely adjusts the wick in the extinguishing set state to the extent that the wick can be extinguished, allowing emergency extinguishing to be carried out by operating the control lever. .

Furthermore, the present invention is not limited to the above first embodiment, and in the present invention, for example,
As in the second embodiment shown in FIG.
2c, and the interlocking pin 53 may be provided on the connecting member 52, and furthermore, the interlocking hole does not necessarily have to be shaped like an angle. If the fine adjustment member 39 or the connecting member 52 can be made large, it may be straight and long. It may also be a hole. Further, by appropriately selecting the interlocking hole, the fine adjustment range of the operating lever 47 can be designed in various ways. Further, the operating force for the operating lever 47 may be obtained from an electric motor or a shape memory alloy coil heated to exceed its transformation point.

<Effects> As is clear from the above explanation, according to the present invention, with the wick lifting member locked at the extinguishing set position by the locking means, the wick adjusting shaft can be moved to the wick lowering side by the operating lever to the extinguishing position. This means that when the fire extinguisher is set, the range of fine adjustment of the fine adjustment material used to finely adjust the wick can be expanded until the fire can be extinguished, and emergency fire extinguishing can be performed by operating the operating lever, so that automatic fire extinguishing equipment, etc. can malfunction for some reason. It has an excellent effect of preventing the occurrence of fire even in the event of a fire.
