Description

Technical Field

[0001] The present invention relates to a holder for a fire extinguisher stick.

Background Art

[0002] Conventional fire extinguishers are generally known to eject white powder in the case of powder-based fire extinguishers. However, when used towards burning articles or equipment, the white powder ejected from the nozzle falls onto the articles or equipment and adheres stubbornly, making it difficult to remove the white powder during post-treatment after extinguishing the fire. When sucking the white powder with a vacuum cleaner, it passes through the filter, causing problems such as malfunction of the vacuum cleaner, and also has an adverse effect on the post-treatment after the fire extinguishing operation, making it difficult to handle and inconvenient.

[0003] As known fire extinguishers for solving this problem, the following Patent Documents 1 and 2 are known. Patent Document 1 discloses a fire extinguisher with less secondary damage by mixing an inert gas and a fire extinguishing liquid in a mixing nozzle to form and release a fine spray. This fire extinguisher forms a fine spray by mixing an inert gas and a fire extinguishing liquid, and releases the fine spray from the mixing nozzle through a hose. By operating the lever, the seal member provided at the outlet of the gas storage part is opened by the unsealing member to allow the compressed inert gas to flow out from the gas outlet, and at the same time, it is introduced into the liquid storage part from the pressurized gas inlet, and the fire extinguishing liquid pressurized by the inert gas flows out from the liquid outlet of the discharge pipe.

[0004] Patent Document 2 discloses a water mist fire extinguisher that does not pose a risk of environmental damage by spraying water in a mist form with a pressurized inert gas. After using the fire extinguisher, the post-treatment becomes water treatment.

Patent Document 1

Patent Document 2

[0006] Commonly available fire extinguishers are heavy, weighing, for example, 5 kg. Because of their weight, these types of fire extinguishers are inconvenient to handle. It is difficult to manually lift heavy fire extinguishers to high places or to maneuver them into confined spaces. Therefore, if a fire occurs at a high place or in a confined space, it may be impossible to perform the desired firefighting operation.

[0007] Patent Document 1 discloses a fire extinguisher that contains a fire extinguishing liquid inside a so-called vertically elongated container, and uses ordinary water, distilled water, or pure water as the fire extinguishing liquid. Therefore, it has been difficult to make the weight of the fire extinguisher body, which contains a certain amount of fire extinguishing liquid required for fire extinguishing, lighter. Furthermore, it is difficult to grasp such a heavy fire extinguisher body with one hand, and if the container is supported with one hand and the nozzle is manually operated with the other hand, it becomes difficult to handle (inconvenient to operate).

[0008] Furthermore, Patent Document 2 discloses a fire extinguisher in which the nozzle is oriented perpendicular to the longitudinal direction of the container. Because the container is placed vertically when not in use and the mist nozzle is positioned perpendicular to the direction of gravity of the vertically oriented container, the operability, which is a criterion for evaluating usability, is poor. Generally, there is a strong demand to complete initial fire suppression (extinguishing the fire within two minutes) when a fire breaks out. Achieving initial fire suppression can significantly reduce the damage and losses caused by fire. Therefore, providing means to achieve initial fire suppression has become a top priority issue that society demands.

[0009] Traditionally, standard fire extinguishers include powder-based, water-based, and gas-based extinguishers. In most cases, all of these fire extinguishers consist of a large-diameter cylindrical container placed vertically on the floor, with a nozzle attached to the outside of the top of the container, or a hose extending from the side of the container with the nozzle at the end of the hose attached to the outer wall of the top of the container. Furthermore, the basic principles of conventionally widely used powder-based, water-based, or gas-based fire extinguishers have remained virtually unchanged for a long period of time.

[0010] The present invention has been made in view of the above-mentioned problems, and its purpose is to provide a holder for a fire extinguishing stick, which is an auxiliary tool for a fire extinguishing stick that further improves the operability and convenience of a small, lightweight, and easy-to-operate fire extinguishing stick. [Means for solving the problem]

[0011] The present invention provides a holder (20, 70, 80, 90) for use as an auxiliary tool for a fire extinguishing stick, or a fire extinguishing device using the same, which is a connecting device for a fire extinguishing stick that can be connected to the hollow cylindrical portion (15) of a fire extinguishing stick (1), and employs a configuration comprising a holder body (21, 71, 81, 91) having an inner wall (22, 95) at one end that can be connected to the outer wall (16) of the hollow cylindrical portion, and a cylinder (41) that is mechanically connected to the holder body and has a grippable cylinder at the other end.

[0012] According to the fire extinguishing stick holder of the present invention, when using a lightweight and compact fire extinguishing stick, the convenience and handling functionality of the fire extinguishing stick itself can be further enhanced as an auxiliary tool. By attaching (fitting) it to the hollow cylindrical part on the handle side of the fire extinguishing stick, the operating position of the hand is moved away from the spray nozzle of the fire extinguishing stick, allowing for quick firefighting operations from a position away from the fire scene.

[0013] By using the holder of the present invention for a fire extinguisher stick, it becomes possible to extinguish fires in gap spaces and high spaces, and the probability of achieving initial fire extinguishing can be significantly improved. Also, by connecting it to an operating rod, fire extinguishing activities can be conveniently carried out remotely.

[0014] For example, when a disk brake of a tire of a large transport truck causes a fire, the driver may not notice and may learn of the fire in his own vehicle upon receiving notice from the passengers of other vehicles. In such a case, the driver can immediately stop the vehicle, remove the in-vehicle fire extinguisher stick and other aids from the cargo bed, attach the holder of the present invention to the fire extinguisher stick, and quickly proceed to the fire extinguishing activity.

[0017] (First Embodiment) A first embodiment of the present invention will be described with reference to Figures 1 to 16 and Figure 31. The fire extinguishing stick holder of the present invention is an auxiliary device that connects to the cylindrical portion (handle) of a fire extinguishing stick.

[0018] (Composition of a fire extinguisher stick) Figures 1 to 3 show examples of fire extinguishing sticks. A fire extinguishing stick is a lightweight, compact, and slender tool used to extinguish fires, serving as an alternative to conventional fire extinguishers. This holder is an auxiliary device that connects to the cylindrical part of the fire extinguishing stick.

[0019] Figure 3 shows a fire extinguishing stick with a protective cap and end cap, Figure 1 shows a fire extinguishing stick with the protective cap removed from the state in Figure 3, and Figure 2 shows a fire extinguishing stick with both the protective cap and end cap removed from the state in Figure 1.

[0020] The fire extinguishing stick 1 comprises a cylindrical metal body 3, an ignition part 7 consisting of an igniter installed at the tip of the body 3, a handle 5 integrally connected coaxially to one end of the body 3 on the opposite end, a detachable resin protective cap 4 that covers the ignition part 7 and the outside of the body 3 from the tip side of the body 3, and an end cap 6 that is detachably attached to one end of the handle 5 on the opposite end.

[0021] The cartridge (not shown) housed in the main unit 3 contains a fire extinguishing agent. The ignition unit 7 is equipped with an ignition agent equivalent to the head of a match. The handle 5 has a hollow cylindrical section 15, with one end having an opening 8 and the other end connected to the base end of the main body 3, and is grippable by the user.

[0022] The protective cap 4 is a hollow cylindrical shape with one end closed, and the protective cap gripping portion 13 at the other end is open. When using the main body 3, the protective cap 4 can be removed from the handle 5 by holding the protective cap gripping portion 13 in the direction of arrow 17 in Figure 3.

[0023] The end cap 6 is detachably provided so as to be able to close the opening 8 of the hollow cylindrical portion 15, and as shown in Figures 4 to 6, a side fitting portion 10 is provided at the tip of the end cap body 9. When attaching the end cap 6 to the hollow cylindrical portion 15, the end cap grip portion 13 is held in the direction of the arrow 18 shown in Figure 4 and the end cap body 9 is fitted into the opening 8. The outer wall of the body 9 and the inner wall of the hollow cylindrical portion 15 slide against each other, and the contact portion 19 of the end cap grip portion 12 contacts the opening 8, positioning it and creating a secure connection between the outer wall of the end cap body 9 and the inner wall of the hollow cylindrical portion 15. When the end cap is attached, the side fitting portion 10 is housed inside the handle 5. When removing the end cap 6, the end cap grip portion 12 is held and pulled out from the opening 8, allowing the end cap 6 to be removed from the hollow cylindrical portion 15.

[0024] (Holder configuration) Next, the holder that can be connected to the fire extinguishing stick 1 will be explained based on Figures 7 to 14. The holder 20 has a hollow cylindrical holder body 21 at one end, which has an inner wall 22 that can be connected to the outer wall 16 of the hollow cylindrical portion 15 that constitutes the handle 5 of the fire extinguishing stick 1, and a grippable cylinder 41 at the other end. The holder body 21 has an opening 23 at one end and a guide tube portion 31 on its bottom side.

[0025] The inner wall 22 of the holder body 21 has a bottom-side first support portion 37 capable of supporting the tip of the hollow cylindrical portion 15 of the fire extinguishing stick 1, and an opening-side second support portion 27 capable of supporting the body of the hollow cylindrical portion. The first support portion 37 has a guide tube portion 31 that extends coaxially from the inner bottom 33 of the holder body 21 along the axis of the holder body 21. The tip of the guide tube portion 31 has a tapered chamfered slope 32 that guides the tip inner wall portion 11 of the hollow cylindrical portion 15 of the fire extinguishing stick 1 to pass through easily. The holder body 21 has a guide tube portion 31 that guides the tip inner wall portion 11 of the hollow cylindrical portion 15 from the radial direction when the hollow cylindrical portion 15 is inserted through the opening 23 of the holder body 21.

[0026] Multiple first protrusions 35 are formed at the base of the guide tube portion 31, extending radially from the axis of the holder body 21. When the opening 8 of the hollow cylindrical portion 15 of the fire extinguishing stick 1 is pushed towards the inner bottom 33, the first protrusions 35 press against the inner wall portion 11 of the tip in a radially outward direction, supporting the hollow cylindrical portion 15.

[0027] The second support portion 27 has a plurality of second protrusions 25 (in this case, five) that project radially inward toward the opening 23 side of the inner wall 22, and these protrusions are formed at equal intervals in the circumferential direction. The second protrusions 25 have an inclined surface that is gently sloped in the axial direction, is convex in the radial direction, and forms a gently curved surface in the circumferential direction.

[0028] The cylinder 41 is formed in a hollow cylindrical shape coaxially with the axis of the holder body 21, extending from the inner bottom 43 opposite to the inner bottom 33 of the holder body 21. The outer diameter of the cylinder 41 is smaller than the outer diameter of the holder body 21. The opening 48 of the cylinder 41 has a conical tapered surface 47 on its inner wall, allowing the operating rod 50 shown in Figure 16B to be inserted. The outer wall of the cylinder 41 is formed to have an outer diameter that is easy to grip and operate. The connecting portion 40 between the cylinder 41 and the holder body 21 is formed so that the outer wall is continuous in a conical inclined shape. Holes 44 and 45 are formed in the cylinder 41, penetrating in the diametrical direction. Lock pins for connecting an operating rod that allows remote control of the fire extinguishing stick can be inserted and fixed into the holes 44 and 45 of the cylinder 41.

[0029] Figure 14 shows the intermediate state of the process of inserting the hollow cylindrical portion 15 of the fire extinguishing stick 1 into the opening 23 of the holder 20 when connecting the fire extinguishing stick 1 and the holder 20. When the hollow cylindrical portion 15 is inserted further towards the inner bottom 33 from the state shown in Figure 14, the inner wall portion 11 at the tip of the hollow cylindrical portion 15 fits with the outer wall of the first protrusion 35.

[0030] Next, we will explain how to use holder 20 based on Figure 15. As shown in Figure 15A, the user removes the protective cap 4 from the main body 3 of the fire extinguishing stick 1 shown in Figure 3, and as shown in Figure 15B, removes the end cap 6 from the handle 5.

[0031] Next, as shown in Figure 15C, the hollow cylindrical portion 15 of the fire extinguishing stick 1 is inserted through the opening 23 of the holder 20. Next, as shown in Figure 15D, the side heating element 10 of the end cap 6 is rubbed against the ignition part 7 of the main body 3 to ignite it. As shown in Figure 15E, when extinguishing a fire by gripping the hollow cylindrical portion 15, which corresponds to the handle of the holder 20, the fire extinguishing stick 1 can be operated manually, and remote control can be performed from the user's hand as far as the holder 20 is attached to. At this time, an inert gas or the like can be sprayed from the tip of the fire extinguishing stick 1 connected to the holder 20 to extinguish the fire.

[0032] (Comparison with comparative forms) Conventional fire extinguishers, as a comparative example, use large-diameter cylindrical metal containers and weigh, for example, 5 kg. The idea of ​​applying the holder of the present invention to such a heavy fire extinguisher would not arise. Using conventional heavy fire extinguishers, it was difficult to spray extinguishing agent at flame sources in high places or in narrow spaces.

[0033] In contrast, the holder of this embodiment is applied to a lightweight fire extinguishing stick, for example, weighing 365g. The holder of this embodiment is applied to a fire extinguishing stick that is significantly smaller, lighter, and more operable and convenient than conventional fire extinguishers in comparative form. The holder of this embodiment is used by attaching it to the hollow cylindrical part corresponding to the handle of the fire extinguishing stick.

[0034] The fire extinguishing stick to which the holder is applied is a so-called fire extinguishing stick that has characteristics not found in conventional fire extinguishers that are widely used. The holder of this embodiment functions as an auxiliary device for the fire extinguishing stick. By using the holder and fire extinguishing stick of the present invention in combination, the efficiency of remotely controlled firefighting activities can be significantly improved. For example, if a fire breaks out at a high place, the fire extinguishing agent can be quickly initiated from the fire extinguishing stick toward the source of the flames.

[0035] As described above, the holder of this embodiment allows for the easy attachment of the holder to a lightweight and easy-to-operate fire extinguishing stick, enabling the use of the fire extinguishing stick holder. This further enhances the convenience, ease of operation, and lightweight / compact advantages of the fire extinguishing stick. Consequently, the possibility of achieving initial fire suppression can be significantly improved.

[0036] (Regarding the action of fire extinguisher sticks) Let me explain an example of how a fire extinguishing stick works.

[0037] When the ignition agent in the main unit 3 is ignited, the components inside the cartridge undergo a chemical reaction, and the extinguishing agent is sprayed from the tip of the main unit 3. Specifically, potassium nitrate and dicyandiamide burn through a chemical reaction, and an inert gas containing white, vapor-like potassium particles is sprayed out. The large amount of potassium radicals depletes the oxygen inside and around the flame, creating a suffocating and suppressive effect that interrupts the combustion chain.

[0038] (Comparison of a fire extinguisher stick with a fire extinguisher) This explanation will compare Fire Extinguishing Stick 1 with a standard fire extinguisher (powder fire extinguisher).

[0039] (1) Spray duration: The fire extinguishing stick can spray continuously for up to 100 seconds, for example. Generally, the first two minutes after a fire starts are called the initial fire extinguishing period, and this has a remarkable effect in achieving initial fire extinguishing. (2) Weight: The fire extinguishing stick (excluding accessories) is lightweight at 365g. Therefore, it is easy to carry in the event of a fire. (3) Residues: Because the fire extinguishing stick sprays an inert gas, no harmful residues are left behind. Therefore, it is easy to restore items and equipment at the site of the fire after it has been extinguished. (4) The fire extinguishing stick can also be used to deal with flammable gas fires that cannot be handled by ordinary fire extinguishers.

[0040] (5) Expiration date: The expiration date for fire extinguishing sticks is 15 years, which is longer than that of general fire extinguishers. (6) Durability: Because the fire extinguishing stick is non-pressurized, it has excellent durability and impact resistance. (7) Periodic inspection: Fire extinguishing sticks do not require periodic inspection by a legally qualified person. (8) Safety and Environment: The fire extinguishing stick uses an inert gas as its propellant. Therefore, it does not adversely affect the breathing or vision of the operator or those nearby, and does not contribute to global warming or ozone layer depletion.

[0041] For reference, the specifications of conventional fire extinguishers are as follows: (1) Spray duration: Conventional fire extinguishers have a spray duration of, for example, about 15 seconds. This often fails to achieve initial fire suppression. (2) Weight: Conventional fire extinguishers are generally heavy, with most weighing around 5 kg. This makes them difficult to carry during a fire. (3) Residues: Standard fire extinguishers leave behind chemical residue and stains after spraying. This makes it difficult to restore items and equipment in the affected area after the fire has been extinguished. (4) Conventional fire extinguishers cannot handle flammable gas fires. (5) Expiry date: Conventional fire extinguishers deteriorate quickly and have a short shelf life. (6) Durability: Conventional fire extinguishers are pressurized, so they have poor durability and impact resistance. (7) Periodic inspections: Conventional fire extinguishers require periodic inspections by legally qualified personnel, and their handling is complicated. (8) Safety and Environment: Conventional fire extinguishers can easily affect the breathing and vision of the operator and those nearby, and are also contributing to global warming and ozone layer depletion.

[0042] (Operation of the Embodiment of the Present Invention) According to this embodiment, the fire extinguishing stick is ignited and an inert gas is sprayed out, similar to manually striking a match. This provides a holder that functions as an auxiliary tool for a small, lightweight, and easy-to-handle fire extinguishing stick, thereby enhancing the usability of the fire extinguishing stick.

[0043] Generally, operating a fire extinguisher of this type required holding the extinguisher body in one hand and manually operating the nozzle with the other, making it inconvenient to use.

[0044] In contrast, according to this embodiment, when starting use, simply remove the cap and perform the ignition operation to spray inert gas from the tip of the fire extinguishing stick. For example, before spraying, the opening 23 of the holder body 21 of the holder 20 of the present invention can be fitted and inserted onto the end of the hollow cylindrical portion 15 of the fire extinguishing stick 1, thereby extending the effective length of the fire extinguishing stick. By gripping the outer wall of the cylinder 41 of the holder 20, the gas sprayed from the tip of the fire extinguishing stick can be easily directed towards the fire. The spray direction can be easily changed by manually operating the holder, allowing for easy firefighting operations.

[0045] As shown in Figure 16B, by attaching the operating rod 50 to the non-stick end of the holder 20, the operating rod 50 can be gripped to remotely control the fire extinguishing stick 1, which is connected to the holder tip on the opposite side of the grip, to inject inert gas in a desired direction. When extinguishing fires at high altitudes, remote control allows for the effective completion of the firefighting process. According to this embodiment, by connecting it to a fire extinguishing stick, it exhibits remarkable effectiveness in extinguishing fires at high places.

[0046] The fire extinguishing stick and holder used in this embodiment can be kept on board large trucks and other vehicles at all times. When kept on board a vehicle under normal circumstances, both the fire extinguishing stick and holder are lightweight, compact, and easy to handle while on board. This significantly increases the probability that initial fire suppression can be carried out by the driver or passenger in the event of a fire originating from the truck's wheels or other parts.

[0047] By connecting the holder 20 to the hollow cylindrical part 15, which is the handle of the fire extinguishing stick, the range of convenience for the fire extinguishing stick is expanded, allowing for, for example, the spraying of inert gas from a position one step forward and enabling remote operation. When mounted in a truck, the fire extinguishing stick can be easily removed from its storage location and attached to the holder with a single touch. After attaching the fire extinguishing stick, rubbing the ignition point on the cap against the ejection end of the fire extinguishing stick immediately releases inert gas from its tip. The inert gas is released from the tip of the stick on the end of the holder held in one hand. Therefore, it is lightweight and easy to handle, and inert gas can be easily released from the tip of the stick towards a target with only one-handed operation.

[0048] (Second embodiment) A second embodiment of the present invention is shown in Figure 16B. The second embodiment is a configuration in which the holder body 21 of the holder 20 is fitted onto the handle 5 of the fire extinguishing stick 1, and a long operating rod 50 is attached to the cylinder 41. This operating rod 50 comprises a basic operating rod 52, a connecting part 54, and an extendable operating rod 53. The connecting part 54 has the function of connecting one end of the basic operating rod 52 and one end of the extendable operating rod, and the position when connected can be varied in the axial direction. By inserting and fixing lock pins (not shown) of the telescopic operating rod 53 into holes 44 and 45 of the cylinder 41, the telescopic operating rod 53 is fixed in the axial direction of the holder 20, and the fire extinguishing stick can be remotely operated by operating the handle 51 of the basic operating rod 52. In addition, the sum of the lengths of the basic operating rod 52 and the telescopic operating rod 53 can be adjusted.

[0049] By attaching a long operating rod 50 to the cylindrical side 41 of the holder 20, firefighting operations can be performed remotely. Since the firefighting stick 1 is lightweight, for example, 365g, inert gas can be ejected from the firefighting stick 1 towards the source of the fire at a high place via the holder 20 by operating the operating rod 50.

[0050] In the second embodiment, as shown in Figure 17A, the user removes the protective cap 4 from the main body 3 of the fire extinguishing stick 1 shown in Figure 3, and as shown in Figure 17B, removes the end cap 6 from the handle 5.

[0051] Next, as shown in Figures 16B and 17C, the hollow cylindrical portion 15 of the fire extinguishing stick 1 is inserted through the opening 23 of the holder 20, one end of the telescopic operating rod 53 of the operating rod 50 is inserted into the opening 48 of the holder 20, and the locking pin (not shown) is fitted into holes 44 and 45 to secure it, thereby attaching the operating rod 50 to the holder 20. Next, as shown in Figure 17D, the side heating element 10 of the end cap 6 is rubbed against the ignition part 7 of the main body 3 to ignite it.

[0052] As shown in Figures 16B and 17E, when performing firefighting activities by gripping the handle 51 on the free end of the operating rod 50, remote operation can be performed from the user's hand to the extent that the holder 20 and the operating rod 50 are attached. Furthermore, by passing the slim fire extinguishing stick 1 and operating rod 50 through narrow spaces, the convenience and ease of operation of the fire extinguishing stick 1 can be utilized to increase the likelihood of achieving initial fire suppression.

[0053] (Third embodiment) A third embodiment of the present invention is shown in Figures 16C, 18, and 19. The third embodiment is a configuration in which the holder body 21 of the holder 20 is fitted onto the handle 5 of the fire extinguishing stick 1, and a long operating rod 50 is attached to the cylinder 41 via an angle changer 56. In addition to the configuration of the second embodiment, this embodiment is equipped with an angle changer 56 between the holder 20 and the operating rod 50. The angle changer 56 is equipped with a locking mechanism 58 that adjusts the angle θ between the axes of the pipes 59 and 60. By adjusting the angle changer 56, the angle of the direction of the gas ejected from the fire extinguishing stick 1 can be adjusted with respect to the axial direction of the handle 51 of the operating rod 50. As shown in Figures 18 and 19, the angle changer 56 allows the lock mechanism 58 to be operated by switching the button 57 on and off to switch the angle θ, thereby allowing the angle θ between the axis of the holder 20 and the axis of the operating rod 50 to be freely adjusted. The connecting part 54 allows the sum of the lengths of the basic operating rod 52 and the telescopic operating rod 53 to be adjusted, similar to the operation of the second embodiment.

[0054] (Fourth embodiment) A fourth embodiment is shown in Figure 20. The holder 70 has a hollow cylindrical holder body 71 with a projection 72 that is convex in the circumferential and radially inward direction on the inner wall of its tip end. The outer wall of the hollow cylindrical portion 15 of the fire extinguishing stick 1 is fixed between the projection 72 and the inner circumferential wall 72 of the holder body 71. The holder body 71 is integrally formed with the cylinder 41, which has a small outer diameter.

[0055] (Fifth embodiment) The fifth embodiment is shown in Figures 21 and 22. The holder 80 is composed of a cylinder 41, a hollow cylindrical holder body 81, and an inner cylinder 82. The holder body 81 and the inner cylinder 82 have a gap 83 extending axially between the two cylinders, and the hollow cylindrical portion 15 of the fire extinguishing stick 1 can be inserted into this axially extending gap 83. The inner wall of the holder body 81 forms a joining surface 85, which can be joined to the outer wall of the hollow cylindrical portion 15 of the fire extinguishing stick 1. The holder body 81 is integrally formed with the cylinder 41, which has a small outer diameter. The holder body 81 has air holes 84 formed therein.

[0056] (Sixth Embodiment) The sixth embodiment is shown in Figures 23 to 29. Figure 30 shows the usage configuration of the sixth embodiment. This holder 90 is an auxiliary device that snap-fits the hollow cylindrical part 15, which corresponds to the handle of the fire extinguishing stick, and the holder body 91. A fire extinguishing stick is a lightweight, compact, and slender tool for extinguishing fires, which replaces conventional fire extinguishers. This holder 90 has a cylindrical part 41 that serves as a gripping part, and by remotely operating the fire extinguishing stick fitted into the holder body 91, an inert gas or the like is sprayed from the tip of the fire extinguishing stick connected to the holder, thereby extinguishing the fire.

[0057] The holder 90 has its holder body 91 extending parallel to the cylinder 41 at positions close to each other in the same direction as the cylinder 41 extends. The fitting portion 96 of the holder body 91 has an arc shape in each cross-section, and the inner wall 95 is formed so as to extend in the same direction as the extension of the cylinder 41 corresponding to the handle. When the fire extinguishing stick 1 is fitted, the inner wall 95 of the fitting portion 96 becomes a joining surface that elastically contacts the outer circumferential and axial surfaces of the outer circumferential wall of the hollow cylindrical portion 15 of the fire extinguishing stick 1, so as to partially enclose the outer circumferential wall of the hollow cylindrical portion 15 of the fire extinguishing stick 1.

[0058] The fitting portion 96 has a tapered surface 94 that facilitates inserting the fire extinguishing stick 1 through the opening 93 and fitting it into the inner wall 95. The fitting portion 96 elastically tightens and fits onto the outer wall of the hollow cylindrical portion 15 of the fire extinguishing stick 1 with a sense of appropriateness.

[0059] The joint 98 mechanically connects and fixes the holder body 91 and the cylinder 41, which corresponds to the handle. The axis lines of the holder body 91 and the cylinder 41 are parallel, and their axis lines are offset from each other on a non-coaxial basis. This improves handling operability by making it easier to elastically fit the fire extinguishing stick into the fitting portion 96 of the holder 90 using a snap-fit ​​system when using the fire extinguishing stick, and also improves the directional control and work operability of the inert gas and other substances sprayed from the fire extinguishing stick during firefighting activities.

[0060] The hollow cylindrical cylinder 41 has holes 44 and 45 corresponding to locking holes to which one end of a long operating rod can be connected. If the claws of a one-touch button (not shown), which serve as a connecting member for the long operating rod 50 as shown in Figure 16B, are elastically fitted into the holes 44 and 45, the operating rod can be fixed to the cylinder 41 using these claws. This allows the fire extinguishing stick to be connected to the operating rod 50 via the holder 90. Therefore, fire extinguishing activities using the fire extinguishing stick can be further carried out by operating the operating rod, enabling fire extinguishing activities from even more remote locations.

[0061] Furthermore, by connecting the cylinder 41 to an angle adjuster 56, such as the one shown in Figures 18 and 19, which allows adjustment of the inclination angle (θ) between the direction in which the operating rod extends and the direction in which the fire extinguishing stick extends, the direction of the inert gas ejected from the fire extinguishing stick can be changed. The basic usage of holder 90 is the same as in the first embodiment, so the explanation will be omitted.

[0062] (Example of use of the embodiment) Figures 23 and 24 show an example of using the holder of the present invention in the event of a fire in a moving large truck. The fire extinguishing stick and the holder of the present invention are pre-loaded onto the truck. The fire extinguishing stick, holder, and operating rod are lightweight and compact, making them easy to install on the vehicle. For example, if a fire breaks out in the rear brake disc of a vehicle, the driver of the vehicle must immediately bring the vehicle to an emergency stop upon notification from another vehicle's crew, retrieve the onboard fire extinguishing stick, holder, and, if necessary, the operating rod, and begin firefighting operations. The example shown in Figure 23 illustrates how the holder 20 is fitted onto the fire extinguishing stick 1 for firefighting. Firefighting can be performed remotely by the length of the holder 20, which is extended by a length that does not overlap with the handle 5.

[0063] The example shown in Figure 24 illustrates the use of the fire extinguishing stick 1 with the holder 20, angle changer 56, and operating rod 50 shown in Figure 16C attached for firefighting. This allows for precise remote operation, targeting the fire source while avoiding harsh environments such as heat and flying embers. This increases the probability of achieving initial fire suppression. According to the holder of the above embodiment of the present invention, it is easy to store and transport in the vehicle space and is convenient to handle. Therefore, it can be used not only when a fire occurs in one's own vehicle but also when a fire occurs in another vehicle, thereby increasing the possibility of performing initial firefighting in an emergency, and improving the disaster prevention effect as a disaster prevention aid.

[0064] While conventional fire extinguishers are large and heavy, making them difficult to carry and use, and therefore unsuitable for initial fire suppression, this invention, when used in conjunction with a fire extinguishing stick, increases the likelihood of achieving initial fire suppression and functions as an excellent auxiliary tool for disaster prevention.

[0065] According to the fire extinguishing stick holder of the present invention, when in use, the holder is stored in the same place or nearby as the small, lightweight, and slender fire extinguishing stick. For example, the fire extinguishing stick can be mounted in a vehicle or installed in a private residence, apartment building, factory, etc. In addition, the holder, angle adjuster, and operating rod, which function as auxiliary devices, are installed in the same place or nearby as the fire extinguishing stick. As a result, in the event of a fire in a vehicle, house, factory, etc., the fire extinguishing stick holder can be used to quickly carry out firefighting operations, increasing the probability of achieving initial fire suppression and increasing the probability of avoiding significant losses.
