Description

[Detailed description of the invention] This invention was devised so that a set of vibrating fire extinguishing devices for up-and-down wick type oil-burning appliances can be set up with one touch when in use.

Examples will be described below with reference to the drawings. Reference numeral 1 denotes a mounting board to be attached to a combustion tank (not shown), and is formed into a substantially U-shape on the side. 2 has a vertical plumb reset projecting piece 3 formed at one end, and a weight 4 swingably placed on the mounting board 1 is connected to the other end by a chain 5.
It is a seismic actuating plate with a guide hole 7 with a locking protrusion 6 in a suitable position, and is pivoted on the back side of the mounting board 1 with a pivot 8, so that when the weight 4 is tilted, the chain 5 uses the pivot 8 as a fulcrum. The projecting piece 3 for resetting the vertical weight is formed so as to rotate downward (counterclockwise), and normally rotate clockwise due to its own weight. 9 is bent upward on both sides, and a locking pin 10 that is engaged with the guide hole 7 of the vibration-sensing actuating plate 2 is provided on one side of the bent piece. A set actuating piece 1 is provided with a receiving claw 11 for supporting the lower surface, is bent into a substantially L shape on the other side of the bent piece, and is pivoted on a pivot 12 so as to be rotatable only clockwise.
3, whose base end is pivotally attached to the surface of the mounting board 1 with a pivot 14, and a spring 15 is stretched between the movable plate 9 and the mounting board 1, so that the pivot 14 is always used as a fulcrum. The movable plate 9 is urged upward (clockwise). 16 is a pivot 14 whose base end is coaxial with the movable plate 9.
The free end is removably engaged with a ratchet wheel 18 inserted through the core adjustment shaft 17, and is also provided so as to be movable toward and away from the vertical plumb reset protrusion 3 of the vibration-sensing actuating plate 2. The lower surface of the locking plate 16 is supported by the receiving pawl 11 of the movable plate 9 by a locking plate to which the locking pin 19 is fixed, and a spring 20 is stretched between the locking plate 16 and the set operation piece 13. At the same time, the set operating piece 13 also rotates the pivot 1.
It is biased downward (counterclockwise) using 2 as a fulcrum.
The ratchet wheel 18 has an operating pin 21 that is removably engaged with the setting operating piece 13 of the movable plate 9, and an operating pin 21 that engages with an operating pin 23 that protrudes from the core adjustment shaft 17.
A locking pin 22 is provided in a protruding manner to rotate the ratchet wheel 18 when the combustion wick is rotated in the upward direction of the combustion wick. Reference numeral 24 is a wick lowering spring which is stretched between a tank (not shown) and the ratchet wheel 18, and is formed so as to store force in the direction of lowering the combustion wick when the wick adjustment shaft 17 is rotated in the direction of raising the combustion wick.

Since the present invention is configured as described above, when extinguishing a fire, the movable plate 9 is rotated upward (clockwise) by the spring 15 and the lower surface is supported by the receiving claw 11. The locking plate 16 that has been rotated upward (clockwise) disengages the locking pin 19 from the ratchet wheel 18, and furthermore, the locking protrusion 6 of the vibration-sensitive actuating plate 2 and the movable plate 9 disengage from each other. The locking with the stop pin 10 is also released. (Figures 2 and 4) At this time, when the weight 4 is tilted, it is impossible to reset it with one touch, so according to the conventional example, a separate reset device is provided, but according to the present invention, this can be done. In this case, a movable plate 9 is pivoted on a pivot shaft 14 by the biasing force of a spring 15, and a locking plate 16 is pivoted on the pivot shaft 14 with its lower surface supported by a receiving claw 11 of the movable plate 9. Since both are rotated upward (clockwise), in the middle of this, the locking pin 19 of the locking plate 16 abuts and locks the lower surface of the vertical plumb reset protrusion 3, and the pivot 8 becomes the fulcrum. Since the weight 4 is rotated upward (clockwise), the chain 5 is pulled and the weight 4 is reset to a state in which it is properly placed on the mounting board 1, and this state is maintained when no combustion occurs.

Next, for combustion, rotate the wick adjustment shaft 17 in the combustion wick upward direction (clockwise).
A locking pin 23 protruding from the locking pin 23 locks the locking pin 22 of the ratchet wheel 18 and rotates the ratchet wheel 18 together to store energy in the core lowering spring 24, while the operating pin of the ratchet wheel 18 21 engages with the set operating piece 13 to rotate the movable plate 9 downward (counterclockwise) against the spring 15. At this time, due to the elastic force of the spring 20, the locking plate 1 is
6 is also moved downward (counterclockwise) to lock the locking pin 19 to the outer pawl of the ratchet wheel 18, and the locking pin 10 of the movable plate 9 moves downward in the guide hole 7 to lock the locking protrusion 6. When the vibration-sensing actuating plate 2 rotates clockwise under its own weight and is locked by the locking protrusion 6, the ratchet wheel 18 and the locking pin 19 are kept locked. By performing 17 rotations, the combustion wick can be raised to a predetermined position and locked, and the combustion wick is ignited and combusted. (Fig. 1) Next, during the above-mentioned combustion operation, if the weight 4 is forcibly swung and tilted when an earthquake or other shock is felt or to perform an emergency fire extinguishment manually, the chain 5 is pulled and the chain 5 is pulled. Since the vibration actuating plate 2 is rotated downward (counterclockwise), the locking pin 10 and the locking protrusion 6 are disengaged, and the movable plate 9
is rotated upward (clockwise) about the pivot 14 as a fulcrum by the tension of the spring 15, and the locking plate 16, whose lower surface is supported by the receiving pawl 11, is also rotated upward (clockwise) and the locking pin is rotated upward (clockwise). 19 and the ratchet wheel 18, the ratchet wheel 1 is released by the accumulated force of the core lowering spring 24.
8 clockwise, the locking pin 22 of the ratchet wheel 18 and the locking pin 23 of the core adjustment shaft 17 engage with each other, and the core adjustment shaft 17 is rotated counterclockwise to instantly extinguish the fire. . At the same time as extinguishing the fire, the weight 4 is
is automatically placed in the correct position on the mounting board 1. (See Figure 2) According to the present invention, the seismic actuating plate 2 is provided with the protrusion 3 for resetting the plumb mass, and the locking pin 19 of the locking plate 16 is provided so as to be able to come into contact with and separate from the locking pin 19, so that the weight 4 is automatically reset when extinguishing a fire. It has the feature of being reset to the correct position. Further, since the set operating piece 13 is rotatably provided on the movable plate 9, and the operating pin 21 that is engaged with the set operating piece 13 is provided on the ratchet wheel 18, the fire extinguishing system can be reset with a single touch when the combustion wick is raised. There are also some features that can be used.
