Reference numeral 57 denotes an actuating plate whose one end is rotatably supported by the shaft support base 18 with a pin 58. When the latch shaft 42 moves forward, the latch 45 is attached to a locking shaft 59 attached to the actuating plate 57. The locking pawl 46 is locked. The other end of the actuating plate 57 is linked with the actuating rod 38 of the above-mentioned vibration-sensing actuating member 36, and when the actuating rod 38 moves upward due to the swinging of the weight 37, the other end of the actuating plate 57 becomes a disk. 41, and the engagement between the latch 45 and the locking shaft 59 is released.

Furthermore, the latch shaft 42 is in a state of being moved forward when the core 6 is raised to the combustion position as shown in FIG. If the return force of the spring 52 does not lower the latch 52, the latch 45 is disengaged from the locking shaft 59, and the latch shaft 42 is forcibly moved manually to the position shown in FIG. 4A. By moving the latch shaft movable body 4 to
8. The core body 6 can be forcibly lowered via the rotating arm 53, the core vertical shaft 14, etc. Therefore, the latch shaft 42 also functions as a manual core lowering means for forcibly lowering the core body 6 by manual operation.

60 is a vertical axis 14 whose base is centered within the supporting base 18;
It is an interlocking lever with a generally dogleg-shaped side that is rotatably pivoted on the side, and the tip of the dogleg-shaped piece 61 is connected to the movable body

Reference numeral 72 designates a fire extinguishing lever pivotally attached to the outer end of the core vertical shaft 14. When the extinguishing button 73 at the tip is moved down, a protruding piece 74 at the other end moves upward, and this protruding piece 74 engages the locking shaft 59. The other end of the actuating plate 57 is lifted to release the engagement between the latch 45 and the locking shaft 59, and the core body 6, which has risen to the combustion position, is suddenly lowered by the biasing force of the spring 52 to extinguish the fire. That's what happens.

Next, the operation of the above configuration will be explained. First, when the push-down button 68 shown in FIG. As this occurs, the interlocking lever 60 rotates counterclockwise about the core vertical shaft 14.

As the interlocking lever 60 rotates, the roller 62 moves the latch shaft movable body 48 from the position shown in FIG. 4A to the position shown in FIG. At the same time, the guide pin 50 rotates the rotating arm 53 counterclockwise, and as the rotating arm 53 rotates, the core vertical shaft 14 also rotates in a direction that raises the core 6 via the crank body 12. do. The latch shaft 42 moves while compressing the spring 52 on the one hand, and the locking pawl 46 of the latch 45 at the other end locks on the locking shaft 59 of the operating plate 57 when the movement of the latch 45 is completed by a predetermined amount. At this time,
The spring 52 of the latch shaft 42 is compressed to store force, and due to the engagement of the locking shaft 49 and the locking pawl 46, the latch shaft 42 maintains the stored force of the spring 52 and remains stationary. With the operations up to this point, the core body 6 has completed its rise to the combustion position, and is held in the raised state by the latch 45.

Next, the operation of the core body 6 will be explained based on FIG. 2. The core body 6 shown in FIG. 2 is in the extinguishing position (lowest lowered position), and from this state the crank operating mechanism 1
The crank body 12 is rotated in accordance with the counterclockwise rotation of the core vertical shaft 14 of No. The core body 6 is raised via the plate 9 and the core support fitting 7. The crank receiving plate 9 can suppress the lateral movement caused by the rotation of the crank body 12 by engaging the small diameter portion 20 at the tip of the core vertical shaft 14 with the vertical elongated hole 10. Performs linear movement only in the direction, and the center vertical axis 1
4, it instantly rises from the extinguishing position to the combustion position by rotating approximately 60 degrees.

Next, the adjustment of the core height of the raised core body 6 will be explained. Due to the engagement between the latch 45 and the locking shaft 59 of the actuating plate 57, the core body 6 remains in the raised state unless the engagement is released, but the latch shaft 42 and the latch 45 are connected by screwing. Therefore, when the rotary knob 43 is rotated, the latch shaft 42 moves slowly in the axial direction relative to the latch 45 which is stationary due to engagement with the locking shaft 59. As the latch shaft 42 moves, the core vertical shaft 14 also rotates by a small angle via the movable body 48 and the rotating arm 53, and this slight rotation of the core vertical shaft 14 adjusts the center height of the core body 6. It will be a clause. Once the core height is adjusted in this way, there is no need to adjust the core height every time the core is raised.

Next, automatic fire extinguishing due to earthquakes, etc. will be explained.
When vibration is applied to the instrument, the vertical plumb 37 of the vibration-sensing actuating member 36
When the actuating plate 57 swings, the actuating plate 57 is moved through the actuating vertical rod 38.
The other end is moved upward, and here the engagement between the locking pawl 46 of the latch 45 and the locking shaft 59 is released, and the latch shaft 42 is instantly moved to its original position by the stored force of the spring 52. Then, the core vertical shaft 14 is reversely rotated via the movable body 48 and the rotating arm 53, and the core body 6 is suddenly lowered to extinguish the fire.

Also, in normal fire extinguishing, when the extinguishing button 73 is pressed down, the extinguishing lever 72 moves the other end of the operating plate 57 upward, reversely rotates the core vertical shaft 14 in the same manner as described above, and causes the core body 6 to descend rapidly. Can extinguish fire.

Next, a case will be described in which the core body 6 is forcibly lowered to the extinguishing position by a manual movement operation. If tar adheres to the upper end of the core 6, even if the engagement between the latch 45 and the locking shaft 59 is released, the biasing force of the spring 52 will not lower the core 6; The state in which it moves forward while disengaging from the stop shaft 59 [see Figure 4 B]
By pressing the latch shaft 42 and moving it rearward (see FIG. 4A), the latch shaft movable body 48 rotates the core vertical shaft 14 clockwise via the rotation arm 53. This clockwise rotation of the core vertical shaft 14 causes the crank body 12 to lower the core body 6 from the combustion position to the extinguishing position.

Furthermore, the latch shaft 42 reciprocates in conjunction with the raising and lowering movement of the core 6, and moves forward when the core 6 is in the combustion position and returns to its original position when the core 6 is in the extinguishing position. The position of the latch shaft 42 makes it easy to confirm that the core 6 has not been lowered to the extinguishing position.

As described above, according to the present invention, when the core cannot be lowered due to the elastic force of the spring for lowering the core, the core can be forcibly moved by moving the core height adjustment body that adjusts the core height position of the core. Since the core is made to be able to be lowered, even if tar or the like is attached to the core and the core cannot be lowered, the fire can be reliably extinguished and safety can be improved. In addition, since the core height adjuster reciprocates in conjunction with the lifting and lowering movement of the core, if the core does not fall to the extinguishing position even though you have tried to extinguish the fire by operating the fire extinguishing button, you can check the situation. This can be easily confirmed by the position of the center height adjuster, further improving safety.

Furthermore, the core height adjuster was used to lower the core, which was unable to move by the force of the spring alone, to the extinguishing position. There is no need to provide it separately, and the configuration can be simplified.
