Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a fire extinguishing device that operates a fire extinguisher valve by pulling down a presser rod with a wire based on impact.

[Conventional technology]

Conventionally, there has been a fire extinguishing system in which a support member is fixed to the head of a fire extinguisher, and a presser rod that passes through the valve head surface of the fire extinguisher head is swingably provided at one end of the support member. −41021 Publication, Publication No. 50-34799
When the presser rod is pushed down, the valve head is pushed and activated to extinguish the fire. The pressing down is usually done manually.

However, in the event of an earthquake or a car accident, a person may be injured and unable to press down, and in this case, the fire extinguishing device described above is of no use. Therefore, even if a fire occurs due to an earthquake, the injured people will not be able to extinguish the fire, resulting in a major accident.

In view of the above points, this invention focuses on the fact that shocks are always generated in earthquakes and car accidents, and aims to make it possible to automatically extinguish fires even with such shocks.

[Means to solve the problem]

In order to solve the above problems, in this invention, a support member 4 is fixed to the head 2 of the fire extinguisher 1, and a presser is attached to the support member 4, which passes through the upper surface of the valve head 3 of the fire extinguisher head 2. A swinging rod 11 is mounted on bases 10 and 20, which are mounted near parts that receive impact, such as the bumper of an automobile.
Alternatively, a sliding rod 21 is provided, the backing plates 12 and 22 are fixed to the tip of the swinging rod 11 or the sliding rod 21, and the wire 8 is guided from the swinging rod 11 or the sliding rod 12 to the presser rod 5. , The swinging rod 1 due to the impact on the backing plates 12 and 22
1 or by sliding the sliding rod 21, the presser rod 5 is pulled down via the wire 8, and the presser rod 5 pushes the valve head 3 of the fire extinguisher 1 to automatically inject the extinguishing agent from the hose 7. We adopted a configuration that allows this.

[Effect]

The fire extinguishing device according to the invention configured in this way has its bases 10 and 20 attached to various members such that the backing plates 12 and 22 face the member receiving impact, such as the bumper of a car, and the fire extinguisher 1 The extinguishing agent spouting hose 7 is directed toward a location where a fire is likely to occur due to its impact.

In this state, if an impact is applied to the bumper etc. and the impact is transmitted to the backing plates 12 and 22, the swinging rod 1
1 swings or the sliding rod 21 slides, and the wire 8
The presser foot 5 is pulled down via the presser foot 5. By this pulling down, the valve head 3 of the fire extinguisher 1 is pushed, the fire extinguisher 1 is activated, and the extinguishing agent is spouted from the hose 7.

〔Example〕

As shown in FIG. 1, a support rod 4 is fixed to the head 2 of the fire extinguisher 1, and a presser rod 5 is attached to one end of the support rod 4.
is swingably provided. This presser foot 5 is
It is supported by a spring 6 through the upper surface of the valve head 3 of the head 2, and when the presser rod 5 is pressed down as shown by the chain line in the figure against the spring 6, the valve head 3 is pressed.
Fire extinguishing agent is spouted from the hose 7.

One end of a wire 8 is fixed to the tip of the presser rod 5, and the wire 8 is guided to the puller A through the hole 4a at the tip of the support rod 4.

As shown in the figure, the puller A is provided with a square-shaped swinging rod 11 in the middle of the base 10 so as to be swingable.
A backing plate 12 is fixed to one end of this swinging rod 11,
The other end of the wire 8 is fixed to the other end.
The wire 8 is housed between the support rod 4 and the base 10 in an outer tube 8a fixed to both 4 and 10, and when the backing plate 12 is pushed, the swing rod 11
When it swings as shown by the arrow, the wire 8 is pulled and the presser rod 5 is pulled down as shown by the chain line. In the figure, 14 is a spring for returning the swinging rod 11.

This embodiment has the above-described configuration. For example, in order to install it on a car, the pull tool A is fixed to its mounting piece 13 at an angle behind the bumper, and the backing plate 12 is
facing the back of the bumper. On the other hand, the fire extinguisher 1 is fixed at an appropriate location, and its hose 7 is connected to an area where a fire is likely to occur due to a collision, for example, an engine room.

In this state, if a car collision occurs and an impact is applied to the bumper, the impact will cause the backing plate 12 to
moves backward, the swinging rod 11 swings, the presser rod 5 is pulled down via the wire 8, and the fire extinguisher 1 is activated.
A fire extinguishing agent is injected from the hose 7 to extinguish the fire.

Figure 2 shows another example of the puller A, which is
A sliding rod 21 is provided on the base 20, and this sliding rod 21
With a backing plate 22 at the tip and a stopper 25 at the rear end,
The wire 8 is fixed thereto. In the figure, 24 is a spring for returning the sliding rod 21.

This puller A is also used in the same manner as described above, and the sliding rod 21 slides as the backing plate 22 retreats due to the impact, and the fire extinguisher 1 is activated via the wire 8.

In the embodiment shown in FIG. 3, the fire extinguisher 1 can be started by a plurality of pullers A, and the support rod 4 is made up of two plates 30, 30, with a presser rod between them. 6 is provided. Each wire 8 from the puller A is fixed to the presser 6 after its outer tube 8a is fixed to a protruding piece 30a of one plate 30.

In this embodiment, each puller A is placed at an appropriate location that is likely to receive an impact, and the fire extinguisher 1 is activated by pulling the wire 8 due to the impact at that one location.

[Effect of idea]

This device is constructed as described above, and is capable of automatically extinguishing a fire due to impact, so even if someone is injured by the impact and the fire extinguisher cannot be activated, the fire will still be extinguished. There are preventive effects.
