Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an injection starting method and a fire extinguishing apparatus therefor. Regarding

[0002]

2. Description of the Related Art A fire causes a great deal of damage, and when it occurs, it is important to extinguish it on the spot as much as possible. Therefore, much research and development has been conventionally performed on fire prevention or extinguishing devices. For example, as one of the devices that automatically detects and extinguishes a fire when it occurs, a sprinkler type is installed on the ceiling, and water is automatically sprinkled when the detector detects a fire. There is a fire extinguishing system.

Furthermore, a commercially available fire extinguisher is used to automatically extinguish a fire by a simple automatic system in which a sensor such as a temperature sensor and a starter using a motor are connected by an electronic circuit. There is a fire extinguisher. However, in such a conventional sprinkler-type fire extinguishing system, the system is large in scale and may be too expensive, so that it is not always easy to install in a general home.

Similarly, in the conventional simple automatic fire extinguisher, since the temperature sensor and the electronic circuit are used, the structure is unexpectedly complicated and the cost is high although it is a simple type. In addition, failure is likely to occur, and moreover, the failed part of the temperature sensor or the electronic circuit is often invisible. If we did not know the failure, there was a risk that it would not work in the event of an emergency, and it was not always sufficient in terms of reliability.

Since this conventional simple automatic fire extinguisher does not have an important function of removing the safety device, that is, pulling out the safety pin, in order to start a commercially available fire extinguisher with this device. It is necessary to remove the safety pin in advance. Therefore, when a fire occurs, it may happen that the driver forgets to remove the safety pin due to dismay and often grips the grip lever for jetting. Eventually, the fire spreads and it falls into a state where it cannot be managed. The conventional device is thus prone to error in the fire extinguishing operation at an early stage and thus has a fatal defect.

[0006]

SUMMARY OF THE INVENTION The present invention is intended to solve the above problems. That is, an object of the present invention is to provide a starting method and a fire extinguisher for a very convenient fire extinguisher which can be easily detached from a safety device and can be activated, and which has a simple structure and is inexpensive. .

And a supporting member that supports and guides the moving wire and is attachable to the main body.

Further, a fire extinguisher for ejecting a fire extinguishing agent by pulling out the safety pin and pushing down the upper lever with respect to the lower lever of the grip lever, which is a moving wire loosely inserted in the lower lever and directly connected to the safety pin. A fire extinguisher including a pressing member provided on the moving wire for pressing the lower lever, and a supporting member that supports the moving wire and guides it and can be attached to the fire extinguisher main body.

[0013] Further, there is a fire extinguishing device in which the wire is loosely inserted in the lower lever via a guide body. Further, the fire extinguisher includes a sensor and a winding portion that winds a wire according to a signal from the sensor. Further, the sensing of the sensor is also present in the fire extinguisher in which the flammable material that suspends the weight cuts and the weight falls.

It has the function of preventing the 14A from being pushed down carelessly, and is a so-called safety valve.

The safety block 13 is pierced and held by the safety pin 12 from above the upper lever 14A. When the safety pin 12 is pulled out, the safety block 13 is tilted to one side. When operating the fire extinguisher,
Pull out the safety pin 12 with your hand, grasp the grip 14,
By pushing down the upper lever 14A against the lower lever 14B with the shaft 15 as a fulcrum, the extinguishant can be injected.

FIG. 2 is a diagram showing the entire fire extinguisher of the present invention. Further, FIG. 3 is a view showing the support member 3, (a) is a side view, and (b) is a top view. First, a support member 3 is attached to the periphery of the main body 1 and is detachable by a tightening band as described later.

The support member 3 is composed of a pair of left and right columns 31A and 31B each having an inverted L shape, and fastening bands 32 and 33 fixed laterally to the columns. , Tightening buckles 32A, 33A
Is equipped with. Therefore, the support member 3 is provided with a buckle 32A for tightening around the main body 1 in the tightening band,
It can be securely fixed using 33A. By adjusting the stop positions of the tightening buckles 32A and 33A, the main body 1 can be freely fixed even if it has different thicknesses.

The supporting member 3 can be easily removed from the main body by removing the tightening buckle. On the other hand, two guide rolls 34 and 35 are provided so as to straddle the left and right upper side portions 36 of the left and right columns 31A and 31B. A board 37 is fixed to the tightening bands 32 and 33 of the support member at the position of the back of the main body, and the board 37 is bent to form a bottom plate 38A abutting on the bottom of the main body. Therefore, the bottom plate 38A prevents the main body from falling off even if the support member 3 is held and pulled up by hand.

A winding drive unit 5 having a function of winding a moving wire W, which will be described later, is attached to the substrate 37. Inside the winding drive unit 5, a motor 51 is provided above the winding drive unit 5 with the protruding portion of the rotating shaft 55 facing upward, and below the motor drive battery 52 is provided. A winding pulley 54 is attached to the tip of the rotary shaft 55. A guide member 53 is arranged near the winding pulley 54.

On the other hand, a movement wire W, which is a motion transmission means, is directly connected to the safety pin 12,
The moving wire W is loosely inserted into the grip 14 via the guide rolls 34 and 35. The loosely inserted moving wire W is connected to the winding pulley 54 of the motor via the guide member 53. Further, the moving wire W includes the upper side portion 36 of the column 31 and the upper lever 1 of the grip 14.
The push-down body 2 is fixed at a position between 4A and 4A.

The push-down body 2 serves to push down the upper lever 14A with respect to the lower lever 14B. The distance between the push-down body 2 and the upper lever 14A is set such that the push-down body 2 comes into contact with the upper lever after at least the moving wire W has moved through the safety pin 12 and will be described later. . In short, the time difference between the timing of pulling out the safety pin and the timing of pushing down the upper lever can be adjusted by the interval between the pushing body and the upper lever.

Here, the moving wire W is attached to the grip 14
Various cases can be considered as a mode that is loosely inserted into
An example (see FIGS. 4 and 5) is given below. In FIG. 4, holes are provided in the upper lever 14A and the lower lever 14B, which are grips, and after the moving wire W has passed through the hole H2 of the upper lever 14A of the grip 14, the holes of the lower lever 14B are similarly provided. It is inserted loosely by passing through. In this case, the moving wire W can be lowered through the side surface of the lever 14B without necessarily passing through the hole of the lower lever 14B.

In FIG. 5, the guide guide body A is attached to the upper lever 14A.
The moving wire W is loosely inserted through the. The guide guide body A is provided with a hole portion H1 having a size large enough for the moving wire W to be inserted, and normally, the upper lever 14 is provided.
To attach to A, the guide pieces A1, A2
It is securely fixed by bending. In this case, the lower lever 14B may or may not be provided with a hole, and when it is provided, it is also free to pass the moving wire therethrough.

By the way, the installation positions of the guide rolls 34, 35 are such that the guide member 53 for one guide roll 35 is installed.
It is more preferable to provide the virtual extension line from the position where the virtual center line extension of the safety pin 12 contacts the surface of the guide roll 34 with respect to the other guide roll 34. . In this way, the winding action of the moving wire-W and the pulling action of the safety pin 12 are mechanically efficient.

The winding drive unit 5 is driven by closing the switch 63 by the sensor 6 having a fire detection function. The sensor 6 is, for example, a cylindrical box-shaped frame 6
0, combustible material 61, weight 62, switch 63, etc.,
A groove 64 for guiding the connecting pin 65B to the frame body 60
Is provided.

A flammable material 61 is attached to the outside of the frame 60 via a stop pin 65A and a connecting pin 65B. When the combustible material 61 burns and cuts, the weight 62 falls,
The switch 63 located at the bottom will be closed. When the switch 63 is closed, the winding drive unit 5 is driven through the electric wire L to wind the wire W.

The fire extinguisher configured as described above is
Start-up injection is performed as follows (see FIG. 6). Now, a fire occurs at a certain ignition source position. When the combustible material 61 of the sensor 6 is burned out by the heat of the flame (a), the weight 62 falls (b),
The switch 63 is turned on (c). This allows the motor-5
2 is energized and starts rotating. Then, the motor rotating shaft 5
The winding pulley 54 attached to 5 starts winding the moving wire W (d).

As a result, the moving wire-W is guided by the guide member 5
3, it is wound up via the guide rolls 34 and 35 (e), and the safety pin 12 is started to be pulled up. Simultaneously upper lever-14
The push-down body 2 provided on the moving wire W between A and the guide roll 35 starts moving downward. At this time, the interval between the push-down body 2 and the upper lever 14A is slightly longer than the moving length of the moving wire-W required to completely remove the safety pin 12 as described above.

That is, the moving wire-W is directly connected to the actuated body, which is the safety pin 12, so that the moving wire-W moves.
Immediately, the safety pin 12 is moved, and the upper lever 14 is moved.
The actuated body A is provided with a space from the push-down body 2 to obtain a time difference. Therefore, at the moment when the moving wire-W has completely pulled out the safety pin 12 from the upper lever 14A (f), the push-down body 2 starts pushing down the upper lever 14A (g). The movement of the moving wire W further lowers the upper lever 14A, and as a result, the extinguishant is ejected from the nozzle 11 (h). Fire is extinguished here.

As described above, the fire extinguishing agent is used to start and inject the fire extinguishing agent to perform appropriate fire extinguishing. However, in the fire extinguishing apparatus of the present invention, the detector may be placed at the ignition source position. It should be installed. In other words, by focusing the nozzle of the fire extinguisher on the ignition point source position,
In an emergency, the fire extinguishing work can be performed unattended automatically and locally at the ignition source position, intensively and surely.

Specifically, as a place for installing the fire extinguisher,
It is possible to envisage kitchens, bathrooms, etc. at home, boilers, plant equipment, etc. at factories, vehicles such as trains, automobiles, etc., and all other installation locations. In the present invention, the safety pin 12 is pulled out and the lower lever of the grip 14 is pulled out.
A fire extinguisher for injecting a fire extinguishing agent by pushing down the upper lever 14A with respect to 14B.
After pulling out 2, the action with a time lag due to the hand of the person, such as pushing down the upper lever 14A, was performed using a movement transmitting means such as a moving wire-W, which is extremely simple in principle, It can be said to be useful.

Although the present invention has been described above, the present invention is
It is needless to say that the present invention is not limited to the embodiment, and various other modifications can be made without departing from the essence thereof. Further, in order to assist the action of pulling out the safety pin by the moving wire or pushing down the upper lever, it is also sufficiently possible to perform it through a lever mechanism or the like. The movement transmitting means is not necessarily limited to the moving wire,
For example, it may be a motion transmission system using gears.

In short, any mechanism may be used as long as there is a time difference between the action timings of the pulling out of the safety pin and the pushing down of the upper lever. In the present invention, since the operation of pulling down the safety pin and the operation of lowering the upper lever can be performed sequentially by simply pulling the moving wire by hand, it is possible to manually inject without using the winding drive unit and the sensor. You are also free to do so. Further, as the combustible substance of the sensor of the present invention, it is possible to employ a substance that melts by heat, a substance that sublimes by heat, etc., in addition to a substance that burns, and as a result, the weight is cut and the weight falls. It is enough.
