Fire extinguisher operating lever

Abstract

This invention provides a fire extinguisher operating lever that enables safe and easy use of unfamiliar fire extinguishers in emergency situations such as fires. [Solution] The operating lever body 20 includes a gripping portion 40 that is gripped together with the fixing lever 5 of the fire extinguisher, a rotating portion 50 that supports the gripping portion 40 so that it can rotate relative to the main container 2, and a hose guide portion 60 that is supported by the rotating portion 50 on the side of the rotating portion 50 opposite to the side where the gripping portion 40 is located. The hose guide portion 60 has a first hose insertion hole 61 through which the hose 11 is inserted at its tip 63. When the gripping portion 40 is gripped, the rotating portion 50 rotates around the pin hole 51, allowing the hose 11 to move within the range of the first hose insertion hole 61 and lifting the hose 11 at the tip 63 of the hose guide portion 60. This suppresses the hose from flapping around when the extinguishing agent is sprayed and allows the extinguishing agent to be sprayed in the correct direction toward the target. This significantly improves the probability of achieving initial fire suppression.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Generally widely used known fire extinguishers include powder-based, water-based, or gas-based fire extinguishers. A cylindrical main body container is placed vertically on the floor surface, and the nozzle at the tip of the hose pulled out from the upper end of the main body container is locked to the outer wall on the side of the main body container. In many cases, the basic principle of the fire extinguisher has not been substantially changed for a long time.

[0006] Conventional fire extinguishers work by carrying the main container to the scene of the fire, detaching the nozzle from the hose, pulling up the operating lever located at the top of the container, and pointing the nozzle towards the fire. This causes the extinguishing agent to be sprayed from the nozzle. Because high-pressure gas is sprayed when the extinguishing agent is released from the nozzle, the nozzle or the hose near the nozzle must be held with one hand, and the nozzle's direction adjusted to direct the gas and extinguishing agent towards the fire.

[0007] If the operator fails to grip the nozzle at the end of the hose with one hand, the nozzle or hose may slip from their palm, causing the hose to thrash about independently. Once the hose begins to move erratically, it becomes difficult to control its uncontrolled motion. When the hose starts to move erratically, it not only hinders the intended firefighting activity, but the extinguishing agent sprayed from the nozzle scatters into the surrounding area, contaminating the floor, walls, equipment, and surroundings, as well as splashing onto the operator's body, resulting in significant losses for cleanup and recovery.

[0008] Furthermore, some standard fire extinguishers include a warning in the instruction manual's "How to Use a Fire Extinguisher" section stating, "Operating without holding the hose or letting go of it can cause the hose to shake violently, which is extremely dangerous."

[0009] In actual use of a standard fire extinguisher, there is often no time to read these kinds of handling instructions, and it is not always possible to properly direct the sprayed powder, water, or high-pressure gas from the nozzle towards the target. Even with regular fire extinguishing training, situations may arise where the operation cannot be reliably performed in an emergency.

[0010] Even if fire extinguishing training is conducted, the reality is that it mostly consists of posing, with little to no practical training involving pressing a lever and spraying fire extinguishing agent from the nozzle at the end of the hose. Even if training is conducted on how to spray the extinguishing agent from a standard fire extinguisher, there is no guarantee that one will be able to perform such an unusual operation correctly in an emergency situation at an actual fire scene.

[0011] Unlike instruction manuals for general household goods, there is room for technical improvement not only in the content of practical training but also in the tools themselves when it comes to emergency products (tools) used only in emergencies. Conventional fire extinguishers are widely distributed and installed throughout Japan, numbering approximately 4.2 million. While existing fire extinguishers are regularly inspected after purchase, for example every six months, the reality is that most of these inspections do not include training on how to hold the hose, operate the lever, and spray high-pressure gas.

[0012] The present invention aims to provide a fire extinguisher operating lever and a fire extinguisher that enable safe and easy use of unfamiliar fire extinguishers in emergency situations such as fire outbreaks. [Means for solving the problem]

[0013] The fire extinguisher operating lever of the present invention is an operating lever for initiating the spraying of fire extinguishing agent from the main container (2) of the fire extinguisher via a hose, The gripping portion (40) is held together with the fixing lever (5) of the fire extinguisher, A rotating part (50) supports the gripping part so that it can rotate with respect to the main container, The rotating portion includes a hose guide portion (60) supported by the rotating portion on the side opposite to the side with the gripping portion, The hose guide section employs a configuration in which a first guide hole (61) for inserting the hose (11) of the fire extinguisher is inserted into the tip (63) on the side opposite to the side with the rotating section.

[0014] According to the fire extinguisher operating lever of the present invention, it is rotatably supported and mounted on the main body container of the fire extinguisher, and the movable lever of the fire extinguisher operating lever can be easily retrofitted by covering an existing movable lever or by replacing an existing movable lever. According to the fire extinguisher operating lever of the present invention, the fire extinguisher operating lever of the present invention can be assembled during the manufacturing of the fire extinguisher in place of the conventional movable lever.

[0015] According to the fire extinguisher operating lever of the present invention and the fire extinguisher using the fire extinguisher operating lever of the present invention, the shape of the fire extinguisher hose can be kept "straight" at the start of firefighting. Because the hose maintains its straightness and extends in a straight shape, the hose does not thrash around freely in three-dimensional space. Therefore, the extinguishing agent discharged from the nozzle is basically ejected in the direction desired by the operator. As a result, the hose can be properly operated towards the fire site without thrashing around, and the scattering of extinguishing agent into the surrounding area can be prevented. This makes it possible to properly handle the direction of the nozzle at the end of the hose without the hose thrashing around when fighting a fire, even in an emergency. This significantly improves the success rate of initial fire suppression.

[0016] The fire extinguisher operating lever of the present invention can be easily retrofitted or replaced on existing fire extinguishers or fire extinguishers that are not yet on sale.

[0017] The fire extinguisher operating lever of the present invention, when applied around the safety pin of an existing fire extinguisher, can be attached to or replaced on the fire extinguisher, thereby increasing the probability of avoiding improper operation that is likely to occur during a fire, from the moment the fire extinguisher is installed inside or outside a house, factory, or other building. Therefore, the incidence of hose flailing, which has occurred for many years when using a fire extinguisher, can be significantly reduced.

[0018] This reduces the risk of disaster and contamination during initial firefighting operations, and significantly improves the effectiveness of supporting genuine firefighting activities, especially initial firefighting.

[0019] According to the operating lever for a fire extinguisher of the present invention, at the fire scene, instead of the three steps of pulling out the safety plug, releasing the nozzle from the main body container, and gripping the operating lever, the fire extinguishing agent can be ejected from the nozzle through the two simple steps of pulling out the safety plug and gripping the operating lever. When ejecting the fire extinguishing agent, the whipping of the hose can be suppressed, and the fire extinguishing agent can be ejected in an accurate direction towards the target. Thereby, the probability of achieving initial fire extinguishing can be significantly improved.

Modes for Carrying Out the Invention

[0021] The following describes the fire extinguisher operating lever according to an embodiment of the present invention, based on the drawings. In addition, substantially identical components in multiple embodiments are denoted by the same reference numerals, and their descriptions are omitted.

[0022] (First Embodiment) An operating lever for a fire extinguisher according to the first embodiment of the present invention will be described with reference to Figures 1 to 7.

[0023] The operating lever body 20, which corresponds to the fire extinguisher operating lever (movable lever) of the present invention, is an elongated member as a whole, as shown in Figures 1 to 7, and the basic shape of its cross-section is U-shaped. The operating lever body 20 can be divided into three parts by function: a gripping part 40 that can be grasped by the operator, a rotating part 50 that can be rotatably supported with respect to a member fixed to the fire extinguisher body 1, and a hose guide part 60 that guides the hose 11. The operating lever body 20 has the gripping part 40, the rotating part 50, and the hose guide part 60 integrally formed.

[0024] Furthermore, the operating lever body 20 has a U-shaped cross-section perpendicular to its longitudinal direction and has legs 201 and 202. The width between the inner walls of leg 201 and leg 202 corresponds to the width between the outer walls of the conventional movable lever 6. As a result, as shown in Figure 8, the operating lever body 20 can be assembled so as to fit over the upper surface of the movable lever 6 of the fire extinguisher body 1. After assembly, the side outer wall of the movable lever 6 faces the inner walls of legs 201 and 202. The space between legs 201 and 202 of the hose guide section 60 forms a passage for the hose 11, guiding the hose 11 and making the overall size of the fire extinguisher body 1, including the hose 11, more compact.

[0025] The rotating part 50 has a claw 81 shown in Figure 6 that can be snap-fitted to a movable lever 6 which is rotatable around a pin 51 shown in Figure 8 that is inserted through a pin hole (not shown) formed in a member fixed to the main body container 2. As shown in Figure 6, the gripping part 40 has the other claw 82. The operating lever body 20 is fixed to the movable lever 6 by the claws 81 and 82 engaging with both ends of the movable lever 6 so as to cover the upper surface of the movable lever 6. When attaching the operating lever body 20 to the movable lever 6, the claws 81 and 82 bend elastically before engaging with both ends of the movable lever 6. This allows the operating lever body 20 to be retrofitted to the movable lever 5.

[0026] The gripping portion 40 is the part that the operator can grip together with the fixing lever 5. Of the gripping portion 40 and the rotating portion 50, at least the rotating portion 50 has a safety pin hole 53 through which the safety pin 7 on the fire extinguisher body side can be inserted after assembly. During firefighting, the safety pin 7 can be pulled out from the main container 2 through the safety pin hole 53.

[0027] The hose guide portion 60 is the part that extends from the rotating portion 50 to the side opposite to the side with the gripping portion 40. The main container 2 has a shape that curves gently towards the shoulder. The tip 63 of the hose guide section 60 has a first hose insertion hole 61, which corresponds to a first guide hole through which the hose 11 can be guided (inserted). This allows the tip 63 of the hose guide section 60 to restrict the direction in which the hose 11 extends. The upper surface 64 of the hose guide section 60 has a second hose insertion hole 62, which corresponds to a second guide hole through which the hose 11 can be guided (inserted). This functions as a relief hole to prevent collision between the hose 11 and the operating lever body 20 when the operating lever body 20 is rotated. When the fire extinguisher is not in use, as shown in Figure 12, the back of the hose 11 can be passed through the second hose insertion hole 62, and the hose 11 can be compactly stored in the fire extinguisher body 1, allowing the hose to be guided in a straight line when the fire extinguisher is in use. When releasing the locking mechanism from the locking part 30 during firefighting operations, the hose 11 changes shape from a curved state to a straight state. The first hose insertion hole 61 of the hose guide part 60 restricts the hose 11 from moving freely, preventing it from extending straight.

[0028] When the gripping portion 40 of the operating lever body 20 is gripped, the rotating portion 50 rotates on the pin 51 as a pivot point, and the tip 63 of the hose guide portion 60 guides the hose guide portion 60 so that it lifts the hose 11. Furthermore, when the nozzle 13 is released from the locking part 30 during firefighting, the first hose insertion hole 61 guides the movement of the hose 11 within an acceptable range, restricting the hose 11 from moving erratically and assisting in the straightening of the hose 11. The operating lever body 20 has a safety pin hole 53 and a second hose insertion hole 62 on its upper surface 64, and an opening 85 on its lower surface. When assembling the operating lever body 20, when assembling the rotating part 50 and the gripping part 40 from the upper side of the movable lever 6, it is possible to house parts of the movable lever 6 and the hose 11 in the space inside the operating lever body 20 through the opening 85. This makes the overall size of the fire extinguisher body 1, including its surrounding equipment, more compact.

[0029] (Fire extinguisher configuration) Figure 8 shows an example of a fire extinguisher to which the above-mentioned fire extinguisher operating lever is applied. The fire extinguisher using the operating lever for the fire extinguisher according to the first embodiment has a basic configuration similar to that of a general fire extinguisher, and includes a cylindrical pressure vessel that encloses a fire extinguishing agent and high-pressure gas.

[0030] The fire extinguisher 1 comprises a main container 2, a main outlet 3, a safety pin 7 that blocks a passage (not shown) inside the main outlet 3, a discharge port 15 that communicates with the pressure chamber of the main container 2 and switches the passage to an open state when the safety pin 7 is pulled out, a fixed lever 5 and a movable lever 6 that intermittently open the passage, an operating lever body 20 that is attached over the movable lever 6, an indicator pressure gauge 8 that detects the pressure in the passage on the inlet side of the operating lever body 20, and a cap 4 that fixes the indicator pressure gauge 8 to the main container 2. One end of the hose 11 is connected to the main body outlet 3, and the other end, the tip, is connected to the nozzle 13. The locking portion 30 formed on the side of the main body container 2 has a locking hole 31 into which the nozzle 13 can be fitted and locked.

[0031] As shown in Figure 9, when the nozzle 13 is locked to the locking part 30, the hose 11 bends and flexes, and the nozzle 13 connected to the hose 11 is locked to the locking part 30.

[0032] When using the fire extinguisher, from the state shown in Figure 9, the safety pin 7 is pulled out in the direction of arrow 9, and the fixing lever 5 and the gripping part 40 of the operating lever body 20 are grasped and activated. The operating lever body 20 then rotates around the pivot point of the rotating part 50, causing the hose guide part 60 to lift, and as shown in Figure 10, the tip 63 of the hose guide part 60 lifts the hose 11 passing through the first hose insertion hole 61. At this time, the hose 11 is lifted with a light feel using the lever principle, and the hose 11 is guided to extend in a straight line. When the hose 11 rises, high-pressure gas and fire extinguishing agent try to flow out from the container body 2 through the body outlet 3, but this causes high-pressure fluctuations in the passage inside the hose 11, causing the hose 11 to thrash around. However, the hose guide part 60 suppresses the thrashing of the hose 11.

[0033] Therefore, the hose 11 is prevented from moving violently, significantly increasing the success rate of initial firefighting, which in turn greatly reduces social losses, economic losses, and psychological damage.

[0034] According to the fire extinguisher using the operating lever of this embodiment, by installing the fire extinguisher body 1 inside or outside a building such as a house or factory after purchasing the fire extinguisher, in the event of an emergency, when the lock on the nozzle 13 and the safety pin 7 are released and the lever is operated, high-pressure gas passes through the body outlet 3 from the body outlet 3, causing pressure fluctuations in the passage. At this time, the hose guide section 60 of the fire extinguisher operating lever 10 restricts the shape change of the hose 11 inserted into the first hose insertion hole 61, guiding the hose 11 to extend straight, thereby suppressing the swaying motion of the hose 11 beyond the main body mounting bracket 16. Even if the gripping motion of the hands is released from the hose 11 when the lever is operated with both hands, it is possible to avoid the fire extinguishing agent scattering from the nozzle 13 into the surrounding area. After spraying begins, the hose guide section 60 restricts the swaying of the hose 11, so that the fire extinguishing agent can be sprayed in the desired and appropriate direction at the fire scene by manual operation.

[0035] At a fire scene, instead of the three-step process of "ping, pong, pan," the extinguishing agent is sprayed from the nozzle with a simple two-step operation: "ping" and "pan." This suppresses hose movement during spraying, allowing the extinguishing agent to be sprayed precisely towards the target. This significantly improves the probability of achieving initial fire suppression.

[0036] According to this embodiment, even if the operator is unfamiliar with the operation, the turbulence of the hose 11 during high-pressure spraying is suppressed, and the fire extinguishing agent can be reliably sprayed in the direction of spraying. The technical ingenuity of this embodiment leads to effective disaster mitigation, and by adopting this device, social losses, economic losses, and psychological damage can be significantly reduced. With this operating lever, the configuration of a conventional fire extinguisher can be used as is, and the operating lever body 20 can be retrofitted to the movable lever. By simply fitting the claws 81 and 82 onto both ends of the movable lever 6, the claws 81 and 82 elastically flex and attach to the movable lever 6, making assembly easy. A fire extinguisher equipped with this operating lever has the effect of enabling accurate, rapid, and error-free firefighting operations.

[0037] (Comparison with comparative example) <Comparative Example 1> Here, we will refer to a standard fire extinguisher (conventional fire extinguisher) as a comparative fire extinguisher. In the comparative fire extinguisher 70 shown in Figure 14, the fire extinguisher body and nozzle are connected by a hose.

[0038] When using a fire extinguisher, if the extinguishing powder, water, or gas is ejected along with the high-pressure gas from the extinguisher body, and the powder, water, or gas is ejected from the nozzle at the end of the hose, and the nozzle is not held properly at that time, the hose will shake as it leaves the user's hand. Once the hose starts shaking, the hose and nozzle will become unstable, not only hindering the intended firefighting activity, but the extinguishing agent ejected from the nozzle at the end of the hose will scatter into the surrounding area, contaminating floors, equipment, buildings, etc., and also falling on the operator's body, resulting in significant losses.

[0039] During the initial operation of a comparative fire extinguisher, if the hose and nozzle are released due to misoperation or carelessness, the hose may shake violently, causing the extinguishing agent sprayed from the nozzle to scatter in an unintended direction. Once the hose begins to shake violently, it is not easy to stop the shaking. The instruction manual for the comparative fire extinguisher states, "Never perform a test discharge." Therefore, the prohibition against test discharge indicates that a problem exists in locations where such comparative fire extinguishers are deployed, as operators are typically unfamiliar with using the fire extinguisher hose.

[0040] As shown in Figure 14, the comparative fire extinguisher 70 is normally operated by placing the bottom surface of the fire extinguisher body 71 on the floor surface 42 in the direction of arrow 43, and gripping the fixed lever 5 and the movable lever 6 with the fire extinguisher body 71 in an upright position. If, for example, both levers are gripped with one hand and the hose 11 is not held with the other hand, the force of the high-pressure gas flowing inside the hose 11 will cause the hose 11 to thrash around, for example in the direction of arrow 44, and once the hose 11 starts to thrash around, it is not easy to stop the thrashing hose 11.

[0041] <Comparative Example 2> As shown in Figure 15, when using the fire extinguisher body 71 in an upright position, holding the fixed lever 5 and the movable lever 6, and lifting the fire extinguisher body 71 off the floor 42, if you lift it with both hands, you will release the hose 11 and the nozzle 13 at the end of the hose, causing the hose 11 to thrash around, and once it thrashes around, it cannot be stopped.

[0042] Similar to Comparative Example 1, the instruction manual states, "Never test-fire a standard fire extinguisher." Therefore, since test-firing is not possible, the operator is usually unfamiliar with operating the fire extinguisher, and there is a risk and challenge that the hose could become uncontrollably dangerous.

[0043] While fire extinguishing drills were conducted, in many cases, the comparative fire extinguishers did not actually receive training in operation. Even when training was carried out, the losses caused by the nozzle malfunction resulting from the aforementioned misoperation or carelessness were enormous, yet no technical solutions for fire extinguishers had been proposed for many years.

[0044] For many years, this issue has been left unresolved, without any effective solutions being offered. The resulting losses due to the inability to effectively use fire extinguishers are immeasurable.

[0045] According to this embodiment, technical improvements have been made to enable easy and reliable spraying of the fire extinguishing agent in the desired direction, even for unfamiliar operators in emergency situations. This leads to effective disaster mitigation, and by adopting this device, social losses, economic losses, and psychological damage can be significantly reduced.

[0046] (Second embodiment) A second embodiment of the present invention is a lever-replaceable type, as shown in Figure 12. In a conventional fire extinguisher, the pivot point (e.g., a rivet, not shown) of the conventional movable lever of the operating lever is removed, and the fire extinguisher is equipped with the fire extinguisher operating lever of the present invention in place of this movable lever. In the second embodiment, the operating lever body 80 shown in Figure 13 is used. The operating lever body 80 is the operating lever body corresponding to the operating lever body 20 in the first embodiment described above. In the configuration shown in Figure 13, components that are substantially the same as those in Figure 1 are denoted by the same reference numerals, and the description of the components of the same parts is omitted. The width between the outer walls of the leg portion 201 and the leg portion 202 is the same as the width between the outer walls of the conventional movable lever 6. The operating lever body 80 has a rotating portion 50 with convex bases 86 that protrude toward the fire extinguisher body 2 on both sides of the portion corresponding to the leg portions 201 and 202, and these bases 86 have pin holes 83, 83. The rotating portion 50 becomes rotatable relative to the main container 2 around rivets (not shown) inserted through the pin holes 83, 84.

[0047] According to this embodiment, the conventional movable lever (6) of an existing fire extinguisher can be easily removed and replaced with the operating lever of this embodiment. The method of using the fire extinguisher with the operating lever of this embodiment, as well as its effects, are the same as those described in the first embodiment.

[0048] (Third embodiment) The third embodiment is a manufacturing-integrated type, in which the movable lever of a typical fire extinguisher's operating lever is replaced at the manufacturing stage with the operating lever body 80 shown in Figure 13 according to the present invention. The configuration of the operating lever body 80 in the third embodiment is basically the same as the configuration of the operating lever body 80 in the second embodiment described above.

[0049] In the third embodiment, the operating lever body 80 has pin holes 83 and 84 inserted through the pin 51 of the fire extinguisher body 1, and the rotating part 50 is rotatable with the pin holes 83 and 84 as the pivot point. According to this embodiment, the operating lever (movable lever) of the present invention can be incorporated during the manufacturing of the fire extinguisher. According to this embodiment, by using the other components of a conventional fire extinguisher except for the movable lever, and by removing the pin that fits into the pinhole, reusing or replacing the pin, and then assembling the operating lever body of the third embodiment, the probability of quickly extinguishing a fire with simple operation during firefighting activities can be greatly improved, as described above.

[0050] (Other embodiments) In the above embodiment of the fire extinguisher operating lever of the present invention, the shape of the first guide hole formed at the tip of the hose guide portion is not limited to the illustrated form. In other embodiments, the shape of the operating lever body of the present invention may be a straight-extending shape. Furthermore, it goes without saying that the pivot point of the rotating part of the operating lever of the present invention may be made of a component other than a rivet.

[0051] The configuration of a fire extinguisher to which the fire extinguisher hose of the present invention is applied is not limited to the configuration of a fire extinguisher described above. As stated above, the present invention is not limited to the embodiments described above, and can be implemented in various forms without departing from its essence.
