Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a manual fire extinguishing system in which a person holds a nozzle and discharges a fire extinguishing agent toward the source of the fire, and in particular, the present invention relates to a manual fire extinguishing system in which a person holds a nozzle and discharges a fire extinguishing agent toward the source of the fire. The present invention relates to a fire extinguishing device in which the internal structure of the activation part which is provided as a structural part that activates the release of extinguishing agent during extinguishing action is improved.

[Prior art]

Conventionally, various manual fire extinguishing devices or fire extinguishers have been proposed and implemented.

For example, in Japanese Utility Model Application Publication No. 64-20867, a fire extinguishing agent discharge nozzle is always attached to a valve opening mechanism of a fire extinguishing agent container to keep it in a non-activated state, and when the nozzle is removed, the valve opening mechanism A fire extinguishing system is disclosed that has a structure in which a fire extinguisher is activated.

[Problem to be solved by the invention]

However, in this type of fire extinguishing device, if the nozzle is inserted and removed in a predetermined direction, it can be easily operated, but if a deviation occurs in the direction of insertion and removal, insertion and removal becomes difficult. In other words, extra pulling force and insertion force are required. In an emergency situation during a fire, operators of fire extinguishing equipment generally do not have the mental capacity to do so, so they may not be able to pull out the nozzle in the correct direction, and the equipment may not be able to be used for fire extinguishing purposes.

On the other hand, in the above conventional fire extinguishing equipment, after the nozzle is removed and used for fire extinguishing activities, the nozzle can be reattached and the valve closed. If you forget to replace it, there is a problem that it becomes useless in extinguishing a fire.

In view of these problems, the present invention provides a fire extinguishing system with extremely good operability that allows the operator to reliably and easily remove the nozzle even in situations where the operator lacks emotional stability due to the outbreak of a fire. It is about providing.

On the other hand, the present invention provides a fire extinguishing device having a structure that prevents the nozzle from being easily reattached once the nozzle has been removed, and has a structure that actively encourages replenishment of extinguishing agent or replacement of the fire extinguishing container.

[Means to solve the problem]

In a manual fire extinguishing system, the present invention has an internal structure of the starting part such that when the extinguishing agent discharge nozzle is pulled out from the starting part, the extinguishing agent container is automatically opened to enable extinguishing agent to be discharged. A simple pivoting mechanism that prevents the extinguishing agent discharge nozzle from being returned to the actuator and returning the extinguishing device to a ready state for use after use, unless the extinguishing agent is refilled or the extinguishing agent container is replaced with a new one. A metal fitting member is provided, and a nozzle guide is provided to allow the operator to reliably and easily pull out the extinguishing agent discharge nozzle during highly urgent fire extinguishing operations, thereby ensuring the fire extinguishing function of the fire extinguisher at all times and improving operability. It was designed to achieve this.

That is, according to the present invention, in a fire extinguishing system configured by integrally incorporating a fire extinguishing agent container, a starting part for starting the valve opening of the container, and a nozzle device for discharging the fire extinguishing agent, the starting part includes: an activation book body attached to the container; an activation lever that activates opening of the extinguishing agent container by pivoting downward from the upper limit position; and one end engaged with the activation lever; A starter lever biasing device that always biases the lever downward from the upper limit position, and a guide hole provided in the starter book body to insert and guide the nozzle tip of the nozzle device into the starter body. A nozzle guide and a nozzle tip of the nozzle device inserted into the nozzle guide are provided so as to be able to pivot from a closing position of the guide hole to a lever holding position that holds the activation lever at the upper limit position. The present invention provides a fire extinguishing device comprising: and a lever holder that is pushed by the activation lever to move to the closing position of the guide hole and stop when the nozzle of the nozzle device is removed. Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

〔Example〕

1 and 2 are cross-sectional views showing the detailed structure of the fire extinguishing system according to the present invention. FIG. 3 is an enlarged partial sectional view illustrating a normal state in which the extinguishing agent discharge nozzle of the nozzle device is installed in a guide hole formed in a nozzle guide of a starting part that activates the opening of the extinguishing agent container; FIG. 4 is a similar sectional view showing the internal state of the starting part when the nozzle is removed from the starting part.

Now, in this embodiment, a pressure accumulation type fire extinguishing system will be explained as an example, but it goes without saying that the present invention is equally applicable to a pressurized type fire extinguishing system.

In FIG. 1, a fire extinguisher 1 of the fire extinguishing system is a fire extinguisher container
Inside this container 2, a fire extinguishing agent (not shown) is sealed and filled under pressure of compressed gas. A valve body 4 is attached to the upper part of the container mouth 3 of the fire extinguishant container 2. An outlet 5 is formed in the valve body 4, and the tip of a hose 6 connected to the outlet 5 is connected to a nozzle device 7. A configuration is provided in which the valve opens when a valve stem 9 (FIGS. 3 and 4) protruding from the upper end of the valve body 4 is pushed down as necessary. The outer casing 10 that integrally houses the fire extinguisher 1, the hose 6, the valve body 4, and the starting part 8 includes a hose 6.
A door 11 is provided so that it can be easily taken out. The pedestal 20 on which the hose 6 is loaded is configured to lift the hose 6 to the same height as the lower end of the door 11. FIG. 2 shows a state in which the door 11 of the outer casing 10 is opened.

Next, the configuration of the starting section 8 will be explained in more detail based on FIG. 3. The valve stem 9 of the valve body 4 is provided so as to protrude toward the bottom of the starting section 8 and is located below the starting lever 12 of the starting section 8 .

The activation lever 12 has a hole 12a at its upper end into which a bottle 13a provided as a tip member of a safety stopper 13 that is sealed with a seal (not shown) and is maintained in a sealed state during normal times is inserted. Time is this safety stopper 13 bottle 1
3a is inserted through the safety stopper guide 14, the activation lever 12 is mechanically maintained in a fixed state at a certain upper limit position (the position shown in FIG. 3), so that the activation lever 12
The activation lever 12 is stopped and held at the upper limit position even though the spring force of the activation spring 15 that presses and urges the activation lever 12 downward is applied. Further, a movable lever presser 16 is interposed between the activation lever 12 and the nozzle 71 at the tip of the nozzle device 7.

The starting section 8 has the nozzle 7 of the nozzle device 7 on its side surface.
1 is provided with a nozzle guide 18 having a guide hole 17 that allows the nozzle device 7 to be inserted into the starting part 8 from the outside. It has a structure that determines and guides you. In normal times, the extinguishing agent container 2 is filled with extinguishing agent, the nozzle device 7 is installed in the starting part 8,
In addition, when the safety bottle 13 is inserted into the hole 12a of the starting part 8 and the starting lever 12 is stopped, the nozzle device 7
A nozzle 71 at the tip of the nozzle 71 is inserted into the guide hole 17 via the nozzle guide 18, and the tip of the nozzle 71 pushes up the lever holder 16, and also pushes up the lever holder 16 and pushes the safety stopper 13 onto the activation lever 12. By fitting in, the activation lever 12 is stably held at the upper limit position shown in FIG. 3. The nozzle device 7 has a nozzle tip 71 and a nozzle lever 72. When in use, the hose 6 is pulled out, the nozzle 71 is directed toward the fire source, and when the operator grasps the nozzle lever 72 with his or her hand, extinguishing agent is ejected. It is configured so that Here, the activation lever 12 and the lever presser 1 are
6 are provided as inexpensive metal fitting elements manufactured by bending sheet metal materials. In particular, the lever presser 16 provided according to the present invention is shown in front and side views in FIGS. 5 and 6. As shown in the figure, it is formed as a simple U-shaped metal fitting member in cross section with a pivoting bottle insertion hole 16a, and is pivotally mounted around the bottle fixed to the main body member 8a of the activation section 8. The lever is mounted so as to be movable between a lever pressing position (the state shown in FIG. 3) in which the activation lever 12 is pressed down in response to . On the other hand, the activation lever 12 is attached to a part of the main body 8a of the activation unit 8, and the activation lever 12 is normally located at the upper limit position, so that the contacts are physically contacted (this state can be turned off). ) Also, a microswitch 19 is provided whose contacts become non-contact (this state is turned on) as the starting lever 12 pivots downward during startup. In other words, when the microswitch 19 is activated, it sends a signal indicating activation to the outside. In the configuration of the above-described embodiment, the activation spring 15 is a coil-shaped spring, but it may be constructed of other leaf springs or the like as long as it has the effect of imparting a biasing action to the activation lever 12.

Next, the operation of the fire extinguishing system according to this embodiment having the above-described configuration will be explained.

After the fire extinguisher 1 of this fire extinguishing system is installed in a predetermined position, the seal is cut and the safety plug 13 is pulled out. At this point, the lever presser 16 and the tip nozzle 71 of the nozzle device 7 are still inserted into the guide hole 17 of the nozzle guide 18, so the activation lever 12 does not operate. Therefore, the microswitch 19 is in an off state. The operator grasps the nozzle device 7 and pulls out the nozzle tip portion 71, which has been installed in the guide hole 17 in advance, according to the guide of the nozzle guide 18. Then, the activation lever 12, which had been locked by the nozzle 71, pivots downward around the bottle 12b and is pushed down by the pressing blade of the activation spring 15, and the valve body 4 is brought to the valve opening position shown in FIG. Displace towards. As a result, the activation lever 12
The valve stem 9, which is pushed upward by compressed gas (not shown) inside the extinguishing agent container 2 and a spring 91 inside the valve body 4, is moved by the internal pressure caused by the compressed gas inside the extinguishing agent container 2 and the spring force of the spring 91. Push down against it. This pushing down action of the activation lever 12 causes the valve opening of the fire extinguishing agent container 2 (
(not shown) is opened. In this state, the extinguishing agent is not yet spouted from the extinguishing agent container 2, but the micro switch 19
turns on and sends a start signal to the outside. Since a fire is a highly urgent abnormality in which the moment is of the essence, it is reported by the initial actions of fire extinguishing operations. Further, the lever presser 16 is in a position (FIG. 4) where the guide hole 17 is closed by the activation lever 12, and when the lever presser 16 is pivoted to this closed position, the nozzle 7 can be easily reattached. It is not possible. Next, the operator carries the nozzle device 7 that he is currently holding toward the fire source. That is, when the nozzle 7 is pulled out from the door 11 of the outer casing 10, the door 11, which has been hooked in advance, comes off from the hook, and the door is urged in the opening direction by the door opening spring force of a spring (not shown). Also, pedestal 2
0 has a hose placed thereon, and since the lowest hose is placed at the same height as the door 11, the hose 6 can be smoothly taken out. (If there is a difference between the housing and the lower end of the door, the hose may get caught.) As a result, since the hose 6 is connected to the nozzle device 7, it can be pulled out together with the hose 6. It is possible to approach and respond to fires that are far away. Furthermore, even if there is a fire near the fire extinguisher, the hose only needs to be carried a necessary distance, and even if the hose 6 is still stored in the fire extinguisher 1, it is not stored in a folded state, so that the fire extinguishing agent can be sprayed out.

Next, the operator directs the tip nozzle 71 of the nozzle device 7 directly toward the fire source and manipulates the nozzle lever 72. As a result, the extinguishing agent passage in the nozzle device 7 is opened, and the extinguishing agent in the extinguishing agent container 2 passes through the coiled hose 6 due to the pressure of the compressed gas via the already open valve. The liquid is ejected from the nozzle device 7. In other words, in the event of a fire within the distance of the coiled hose 6, the operator can spray extinguishing agent toward the source of the fire very naturally by simply grasping and operating the nozzle device 7 with one hand, regardless of other components. This makes it possible to extinguish the fire initially. In this embodiment, the starting part of the pressure accumulation type fire extinguishing system has been described, but it goes without saying that a type without a valve, such as a seal-breaking mechanism, may also be used.

Further, according to the present invention, after the nozzle 71 at the tip of the nozzle device 7 is pulled out from the main body 8a of the starting part 8 and the extinguishing agent is released, the presser lever 16 is moved as described above.
The guide hole 17 of the nozzle guide 18 is closed internally. Moreover, the blocked state can be fixed by removing the starting part 8 from the fire extinguisher 1 and filling the fire extinguishing agent container 2 with fire extinguishing agent, or by replacing the fire extinguishing agent container 2 itself with a new one. The nozzle 71 at the tip of the nozzle device 7 cannot be installed in the main body 8a of the starting section 8 until after the nozzle 71 is pushed up to the upper limit position. Therefore, the state in which the nozzle device 7 is attached to the starting part 8 guarantees that the fire extinguishing device is ready for use at any time.

〔effect〕

As is clear from the above explanation, the fire extinguishing device of the present invention is
Since the activation lever is held at a constant immovable upper limit position by a safety plug and a lever presser attached to the nozzle, it is stable and ready for use under normal conditions. In addition, since a nozzle guide is provided in the starting part, the direction of the nozzle removal hole is fixed, making it easy to remove the nozzle even when an ordinary operator is panicked or upset in an emergency situation such as a flame outbreak. obtain. Furthermore, when the nozzle of the nozzle device is removed from the activation section, an activation signal can be sent to the outside, which has the effect of quickly carrying out countermeasures following the operation of the fire extinguishing device. Moreover, once the nozzle of the fire extinguisher is removed, it cannot be easily re-inserted, so the fire extinguisher is not installed with the inside of the fire extinguisher container empty.
