Description

[Technical field]

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

[0002] Conventional fire extinguishers are generally known to spray white powder, but when used toward burning objects or equipment, the white powder sprayed from the nozzle falls onto the objects or equipment and adheres tenaciously, making it difficult to remove the white powder during post-processing after extinguishing the fire. When the white powder is sucked up with a vacuum cleaner, it passes through the filter, causing problems such as vacuum cleaner failure, and also adversely affecting post-processing after the fire extinguishing operation, making it difficult to handle and inconvenient.

[0003] Known fire extinguishers that solve this problem are disclosed in the following Patent Documents 1 and 2. Patent Document 1 discloses a fire extinguisher that causes little secondary damage by mixing inert gas and extinguishing liquid in a mixing nozzle to form a fine spray and then releasing it. This fire extinguisher forms a fine spray by mixing inert gas and extinguishing liquid, and releases the fine spray from the mixing nozzle through a hose. By operating a lever, a seal member provided at the outlet of the gas storage section is opened by a seal-breaking member, causing the compressed inert gas to flow out from the gas outlet and to be introduced into the liquid storage section from the pressurized gas inlet, and the extinguishing liquid pressurized by the inert gas to flow 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 using pressurized inert gas. After use of the fire extinguisher, water treatment is required. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2012-55360 A [Patent Document 2] JP 2004-135742 A Summary of the Invention [Problem to be solved by the invention]

[0006] A known fire extinguisher that is widely used in general is a heavy object, weighing, for example, 5 kg. This type of fire extinguisher is inconvenient to handle because of its weight. It is difficult to manually lift a heavy fire extinguisher to a high place or to manually bring the fire extinguisher close to a narrow space, so that if a fire occurs at a high place or in a narrow space, it is not possible to perform the desired fire extinguishing work.

[0007] Patent Document 1 discloses a fire extinguisher that contains extinguishing liquid inside a so-called vertically long container and uses normal water, distilled water, or pure water as the extinguishing liquid. Therefore, it is difficult to reduce the weight of the fire extinguisher body that contains a certain amount of extinguishing liquid required for extinguishing a fire. In addition, it is difficult to hold 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, there is a problem that the handling operation becomes difficult (operation becomes inconvenient).

[0008] Patent Document 2 discloses a fire extinguisher in which the nozzle is oriented in a direction perpendicular to the longitudinal direction of the container. The container is placed vertically when stored unused, and the mist nozzle is provided in a direction perpendicular to the direction of gravity of the vertical container, resulting in poor operability, which is an evaluation criterion for ease of use. In general, there is a strong demand for early fire extinguishing (extinguishing within 2 minutes) when a fire occurs. Achieving early fire extinguishing can significantly reduce damage and losses caused by fire. For this reason, providing a means to achieve early fire extinguishing is an important issue that is given top priority in society.

[0009] Fire extinguishers with a conventional standard configuration include powder, water, or gas type fire extinguishers. In all cases, a large-diameter cylindrical container is placed upright on the floor and a nozzle is provided on the outside of the top end of the container, or a hose is pulled out from the side of the container and the nozzle at the end of the hose is attached to the outer wall of the top end of the container. Furthermore, the basic principles of the powder, water or gas type fire extinguishers which have been widely used up until now have not been substantially changed for a long time.

[0010] The present invention has been made in consideration of the above-mentioned problems, and its object is to provide a fire extinguisher stick holder that serves as an auxiliary device for a fire extinguisher stick, further improving the operability and convenience of a small, lightweight, and easy-to-operate fire extinguisher stick. [Means for solving the problem]

[0011] The holder (20, 70, 80, 90) serving as an auxiliary device for a fire extinguisher stick of the present invention, or a fire extinguisher using the same, is a connecting device for a fire extinguisher stick that can be connected to the hollow cylindrical portion (15) of a fire extinguisher stick (1), and is configured to include 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 can be held at the other end.

[0012] The fire extinguisher stick holder of the present invention can serve as an auxiliary tool when using a lightweight and small fire extinguisher stick, thereby further enhancing the convenience and handling function of the fire extinguisher stick itself. By attaching (fitting) it to the hollow cylindrical part on the handle side of the fire extinguisher stick, the operating position of the hand is moved away from the spray part of the fire extinguisher stick, allowing fire extinguishing activities to be carried out quickly from a location away from the fire scene.

[0013] By using the holder of the present invention on a fire extinguishing stick, it is possible to extinguish fires in narrow spaces or high places, and the probability of extinguishing a fire in its early stages can be significantly improved. In addition, by connecting it to a control stick, fire extinguishing activities can be conveniently performed by remote control.

[0014] For example, if the disc brakes of the tires of a large transport truck cause a fire, the driver may not notice the fire and may only become aware of it when a passenger in another vehicle notifies him. In that case, he can bring his vehicle to an emergency stop, remove the fire extinguisher stick and other auxiliary tools from the loading platform, attach the holder of the present invention to the fire extinguisher stick, and quickly move on to firefighting activities.

[0016] Hereinafter, a fire extinguisher stick holder according to an embodiment of the present invention will be described with reference to the drawings. Note that, in a plurality of embodiments, substantially the same components are designated by the same reference numerals, and description thereof will be omitted.

[0017] First embodiment A first embodiment of the present invention will be described with reference to FIGS. 1 to 16 and 31. FIG. The fire extinguisher stick holder of the present invention is an auxiliary device that is connected to the cylindrical part (handle) of a fire extinguisher stick.

[0018] (Fire stick configuration) 1 to 3 show an example of a fire extinguisher stick. A fire extinguisher stick is a lightweight, small, and slender tool for putting out fires that replaces conventional fire extinguishers. This holder is an auxiliary device that is connected to the cylindrical part of the fire extinguisher stick.

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

[0020] The fire extinguisher stick 1 comprises a cylindrical metal body 3, an ignition part 7 consisting of an ignition agent placed at the tip of the body 3, a handle 5 coaxially connected to one end of the body 3 opposite the tip, a removable resin protective cap 4 which 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 which is removably attached to one end of the handle 5 opposite the body.

[0021] A cartridge (not shown) housed in the main body 3 contains a fire extinguishing agent. The ignition unit 7 includes an ignition agent equivalent to the head powder of a match. The handle 5 has a hollow cylindrical portion 15 having a hollow cylindrical shape, one end of which has an opening 8, and the other end of which is connected to the base end side of the main body 3 and can be gripped by the user.

[0022] The protective cap 4 is a hollow cylinder with one end closed and a protective cap gripping portion 13 at the other end which 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 the arrow 17 relative to the handle 5 in Figure 3.

[0023] The end cap 6 is provided so as to be detachable and capable of closing the opening 8 of the hollow cylindrical portion 15, and as shown in Figs. 4 to 6, a side medicine portion 10 is provided at the tip of the end cap body 9. When the end cap 6 is attached to the hollow cylindrical portion 15, the end cap body 9 is fitted into the opening 8 by holding the end cap gripping portion 13 in the direction of the arrow 18 shown in Fig. 4, and the outer wall of the body 9 slides against the inner wall of the hollow cylindrical portion 15, and the abutting portion 19 of the end cap gripping portion 12 abuts against the opening 8, positioning is performed, and the outer wall of the end cap body 9 and the inner wall of the hollow cylindrical portion 15 are joined with a sense of moderation. When the end cap is attached, the side medicine portion 10 is accommodated inside the handle 5. When the end cap 6 is removed, the end cap 6 can be removed from the hollow cylindrical portion 15 by holding the end cap gripping portion 12 and pulling it out from the opening 8.

[0024] (Holder configuration) Next, a holder connectable to the fire extinguisher stick 1 will be described with reference to FIGS. The holder 20 has at one end a hollow cylindrical holder body 21 having an inner wall 22 connectable to the outer wall 16 of the hollow cylindrical portion 15 constituting the handle 5 of the fire extinguisher stick 1, and at the other end a grippable cylinder 41. The holder body 21 has an opening 23 at one end and a guide tube portion 31 on the bottom side.

[0025] The inner wall 22 of the holder body 21 has a first support portion 37 on the bottom side capable of supporting the tip portion of the hollow cylindrical portion 15 of the fire extinguisher stick 1, and a second support portion 27 on the opening side capable of supporting the body portion of the hollow cylindrical portion. The first support portion 37 is formed with a guide tube portion 31 extending coaxially from the inner bottom 33 of the holder body 21 along the axis of the holder body 21. A tapered, chamfered slope 32 is formed at the tip of the guide tube portion 31 to guide the tip inner wall portion 11 of the hollow cylindrical portion 15 of the fire extinguisher stick 1 so as to facilitate insertion. The holder body 21 has the guide tube portion 31 which guides the tip inner wall portion 11 of the hollow cylindrical portion 15 from the radially inward direction when the hollow cylindrical portion 15 is inserted from the opening 23 of the holder body 21.

[0026] A plurality of first protrusions 35 extending radially from the axis of the holder body 21 are formed at the base of the guide tube portion 31. When the opening 8 of the hollow cylindrical portion 15 of the fire extinguisher stick 1 is pushed into the inner bottom 33, the first protrusions 35 press the tip inner wall portion 11 in the radially outward direction to support the hollow cylindrical portion 15.

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

[0028] The cylinder 41 is formed in a hollow cylindrical shape from the inner bottom 43 on the opposite side of the inner bottom 33 of the holder body 21 coaxially with the axial center line of the holder body 21. The outer diameter of the cylinder 41 is smaller than that of the holder body 21. The opening 48 of this cylinder 41 has a conical tapered surface 47 on the inner wall so that the operating rod 50 shown in FIG. 16B can be inserted. The outer wall of the cylinder 41 is formed with 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 the shape of a conical inclined surface. The cylinder 41 has holes 44 and 45 that penetrate in the diameter direction. A lock pin for connecting an operating rod that enables remote operation of the fire extinguishing stick can be inserted and fixed in the holes 44 and 45 of the cylinder 41.

[0029] 14 shows a state in the middle of inserting the hollow cylindrical portion 15 of the fire extinguisher 1 from the opening 23 of the holder 20 when connecting the fire extinguisher 1 and the holder 20. When the hollow cylindrical portion 15 is inserted further toward the inner bottom 33 from the state shown in FIG. 14, the tip inner wall portion 11 of the hollow cylindrical portion 15 fits into the outer wall of the first protrusion 35.

[0030] Next, how to use the holder 20 will be described with reference to FIG. As shown in FIG. 15A, the user removes the protective cap 4 from the body 3 of the fire extinguisher stick 1 shown in FIG. 3, and as shown in FIG. 15B, removes the end cap 6 from the handle 5.

[0031] Next, as shown in FIG. 15C, the hollow cylindrical portion 15 of the fire extinguisher stick 1 is inserted into the opening 23 of the holder 20. Next, as shown in FIG. 15D, the side charge portion 10 of the end cap 6 is rubbed against the ignition portion 7 of the main body 3 to ignite it. As shown in Fig. 15E, when extinguishing a fire by gripping the hollow cylindrical portion 15 corresponding to the handle of the holder 20, the fire extinguisher stick 1 can be operated manually and remotely operated from the hand as much as the holder 20 is attached. At this time, inert gas or the like can be sprayed from the tip of the fire extinguisher stick 1 connected to the holder 20 to put out the fire.

[0032] (Comparison with comparative form) The conventional fire extinguisher for comparison uses a large diameter cylindrical metal container and is heavy, weighing, for example, 5 kg. The idea of ​​applying the holder of the present invention to such a heavy fire extinguisher would not have occurred to anyone. It was difficult to spray extinguishing agent at a flame source in a high place or in a narrow space by using the conventional heavy fire extinguisher for comparison.

[0033] In contrast, the holder of this embodiment is applied to a lightweight fire extinguisher stick weighing, for example, 365 g. The holder of this embodiment is applied to a fire extinguisher stick that is significantly smaller, lighter, easier to operate, and more convenient than a conventional fire extinguisher of a comparative form. The holder of this embodiment is attached to the hollow cylindrical part that corresponds to the handle part of the fire extinguisher stick.

[0034] The fire extinguishing stick, which has a fire extinguishing function for the other party to which the holder is applied, is a so-called fire extinguishing stick that has characteristics not found in conventional comparative fire extinguishers that are widely used in the general public. The holder of this embodiment functions as an auxiliary device for the fire extinguishing stick. By using the holder and the fire extinguishing stick in combination, the efficiency of remote-controlled fire fighting can be significantly improved. For example, when a fire originates at a high altitude, the fire extinguishing stick can start to spray the fire extinguishing agent toward the source of the fire in a short time.

[0035] According to the holder of the present embodiment, as described above, the holder can be easily attached to the light-weight and easy-to-operate fire extinguisher stick, and the holder for the fire extinguisher stick can be used. Therefore, the convenience, operability, and light-weight and small-sized advantages of the fire extinguisher stick can be further enhanced. Therefore, the possibility of realizing early-stage extinguishing can be greatly improved.

[0036] (About the function of the fire extinguishing stick) An example of the function of the fire extinguisher stick will now be described.

[0037] When the ignition agent in the main body 3 is ignited, the ingredients inside the cartridge undergo a chemical reaction, and the extinguishing agent is sprayed from the tip of the main body 3. In detail, potassium nitrate and dicyandiamide combust through a chemical reaction, and an inert gas containing white vapor-like potassium particles is sprayed. The large amount of potassium radicals have a suffocating and suppressing effect that depletes the oxygen inside and around the flame, interrupting the chain of combustion.

[0038] (Comparison between the fire extinguisher stick and a comparable type of fire extinguisher) The fire extinguisher stick 1 will be explained in comparison with a general fire extinguisher (powder fire extinguisher).

[0039] (1) Spray time: The fire extinguishing stick can be sprayed continuously for up to 100 seconds. Generally, the initial fire extinguishing period is said to be two minutes from the start of a fire, but this is a significant effect in achieving initial fire extinguishing. (2) Weight: The fire extinguisher stick (excluding accessories) is lightweight at 365g, making it easy to carry in the event of a fire. (3) Residues: Fire extinguishing sticks spray inert gas, so no harmful residues remain. This makes it easy to restore items and equipment in the affected area after the fire is extinguished. (4) Fire extinguisher sticks can also be used to treat flammable gas fires that general fire extinguishers cannot handle.

[0040] (5) Expiration date: The expiration date of the fire extinguisher stick is 15 years, which is longer than that of ordinary fire extinguishers. (6) Durability: The fire extinguisher stick is non-pressurized, making it highly durable and impact resistant. (7) Regular inspection: Fire extinguisher sticks do not require regular inspection by a legally qualified person. (8) Safety and environment: The gas used to propel the fire extinguisher is an inert gas. This means that it does not adversely affect the breathing or eyesight of the operator or those around, and it does not contribute to global warming or the destruction of the ozone layer.

[0041] In comparison, the specifications of a conventional fire extinguisher for comparison are as follows for reference: (1) Injection time: Conventional fire extinguishers have an injection period of, for example, about 15 seconds. In many cases, they are unable to extinguish a fire in its initial stage. (2) Weight: Conventional fire extinguishers are generally heavy, weighing about 5 kg. This makes them difficult to carry in the event of a fire. (3) Residues: General fire extinguishers leave chemical residue and dirt behind after spraying, making it difficult to restore items and equipment in affected areas after the fire is extinguished. (4) Conventional fire extinguishers cannot handle flammable gas fires. (5) Expiration date: Conventional fire extinguishers deteriorate quickly and have a short expiration date. (6) Durability: Conventional fire extinguishers are pressurized, so they have poor durability and impact resistance. (7) Regular inspection: Conventional fire extinguishers require regular inspection by a legally qualified person, and are complicated to use. (8) Safety and the Environment: Conventional fire extinguishers can affect the breathing and eyesight of the operator and those around them, and are also a cause of global warming and destruction of the ozone layer.

[0042] (Operation of the embodiment of the present invention) According to this embodiment, the fire extinguisher stick is ignited and inert gas is sprayed out in the same way as manually striking a match, and a holder can be provided that functions as an auxiliary tool for the fire extinguisher stick that is small, lightweight, and easy to handle, thereby increasing the utilization of the fire extinguisher stick.

[0043] Generally, when operating a fire extinguisher of the comparative type, it is necessary to hold the body of the fire extinguisher in one hand and manually operate the nozzle with the other hand, which is time-consuming and inconvenient to operate.

[0044] In contrast, according to this embodiment, when starting to use the fire extinguisher, simply remove the cap and turn the ignition on, and inert gas will be sprayed from the tip of the fire extinguisher stick. For example, before ejection, the opening 23 of the holder body 21 of the holder 20 of the present invention is fitted and inserted into the end of the hollow cylindrical portion 15 of the fire extinguisher 1, thereby extending the effective length of the fire extinguisher, and the gas ejected from the tip of the fire extinguisher can be easily ejected toward the fire by grasping the outer wall of the cylinder 41 of the holder 20. The ejection direction can be changed by manually operating the holder, allowing fire extinguishing activities to be carried out with simple operations.

[0045] By attaching an operating rod 50 to the anti-stick end of holder 20 as shown in Figure 16B, by grasping the handle 51 on the free end side of the operating rod 50, it is possible to remotely control the tip of the fire extinguisher stick 1 connected to the tip of the holder on the side opposite to the gripping side so that inert gas is ejected in the desired direction. When extinguishing a fire at a high altitude, extinguishing the fire at a high altitude can be completed effectively through remote control. According to this embodiment, by connecting it to a fire extinguishing stick, it is extremely effective in extinguishing fires at high altitudes.

[0046] The fire extinguisher stick and holder used in this embodiment can be permanently installed in a vehicle such as a large truck. When normally kept in the vehicle, both the fire extinguisher stick and holder are lightweight, small in volume, and easy to operate when installed in the vehicle, and when a fire breaks out from the wheels of the truck, the driver or passenger can greatly increase the probability of carrying out initial fire extinguishing by operating them.

[0047] By connecting the holder 20 to the hollow cylindrical portion 15, which is the handle portion of the fire extinguisher stick, the useful area of ​​the fire extinguisher stick can be expanded, and for example, inert gas can be sprayed from a position one step forward, making it possible to operate it remotely. If it is mounted on a truck, it can be removed from the mounting location and the fire extinguisher stick can be attached to the holder with a single touch. After attaching the fire extinguisher stick, the ignition point of the cap is rubbed against the ejection end of the fire extinguisher stick, and inert gas can be immediately sprayed from the tip of the fire extinguisher stick. Inert gas is sprayed from the tip of the stick on the tip side of the holder held in one hand. Therefore, it is lightweight and easy to handle, and inert gas can be easily sprayed from the tip of the stick toward the target by simply operating it in one hand.

[0048] Second Embodiment A second embodiment of the present invention is shown in FIG. 16B. In the second embodiment, the holder body 21 of the holder 20 is fitted onto the handle 5 of the fire extinguisher 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 a telescopic operating rod 53. The connecting part 54 has a function of connecting one end of the basic operating rod 52 and one end of the telescopic operating rod, and the position when connected can be changed in the axial direction. The telescopic operating rod 53 is fixed in the axial direction of the holder 20 by inserting and fixing a lock pin (not shown) of the telescopic operating rod 53 into the holes 44, 45 of the cylinder 41, 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] If a long operating rod 50 is attached to the cylinder 41 side of the holder 20, fire extinguishing activities can be performed by remote control. Since the fire extinguishing stick 1 is lightweight, for example, weighing 365 g, by operating the operating rod 50, inert gas can be sprayed from the fire extinguishing stick 1 toward the source of a fire at a high place via the holder 20.

[0050] To use the second embodiment, the user removes the protective cap 4 from the body 3 of the fire extinguisher stick 1 shown in FIG. 3 as shown in FIG. 17A, and removes the end cap 6 from the handle 5 as shown in FIG. 17B.

[0051] Next, as shown in Figures 16B and 17C, the hollow cylindrical portion 15 of the fire extinguisher 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 lock pin (not shown) is fitted into and fixed in the holes 44 and 45, thereby attaching the operating rod 50 to the holder 20. Next, as shown in FIG. 17D, the side charge portion 10 of the end cap 6 is rubbed against the ignition portion 7 of the main body 3 to ignite it.

[0052] As shown in Figs. 16B and 17E, when carrying out firefighting activities by gripping the handle 51 on the free end side of the operating rod 50, remote control can be performed from the hand by the amount of the holder 20 and the operating rod 50 attached. Furthermore, the slim fire extinguisher stick 1 and operating rod 50 can be inserted into narrow spaces, making it possible to take advantage of the convenience and ease of use of the fire extinguisher stick 1 and increase the possibility of extinguishing a fire in its initial stages.

[0053] Third embodiment A third embodiment of the present invention is shown in FIGS. 16C, 18 and 19. In the third embodiment, the holder body 21 of the holder 20 is fitted onto the handle 5 of the fire extinguisher 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 includes an angle changer 56 between the holder 20 and the operating rod 50. The angle changer 56 includes a locking mechanism 58 that adjusts the angle θ between the axes of the tubes 59 and 60. By adjusting the angle changer 56, the angle of the direction of the gas ejected from the fire extinguisher stick 1 can be adjusted relative to the axial direction of the handle 51 of the operating rod 50. 18 and 19, the angle changer 56 can fix or release the angle θ by operating a locking mechanism 58 by turning a button 57 on or off, and can freely adjust the angle θ between the axis of the holder 20 and the axis of the operating rod 50. 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 in the same way as in the second embodiment.

[0054] Fourth embodiment A fourth embodiment is shown in FIG. The inner wall of the tip end of the hollow cylindrical holder body 71 of the holder 70 has a projection 72 that is convex in the circumferential direction and extends radially inward. The outer wall of the hollow cylindrical portion 15 of the fire extinguisher stick 1 is fixed between the projection 72 and the inner wall 72 of the holder body 71. The holder body 71 is formed integrally with a cylinder 41 having a small outer diameter.

[0055] Fifth embodiment A fifth embodiment is shown in FIGS. 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 in the axial direction between the double cylinders, and the hollow cylindrical portion 15 of the fire extinguisher stick 1 can be inserted into this axially extending gap 83. The inner wall of the holder body 81 serves as a joining surface 85 to which the outer wall of the hollow cylindrical portion 15 of the fire extinguisher stick 1 can be joined. The holder body 81 is formed integrally with the cylinder 41, which has a small outer diameter. The holder body 81 has an air hole 84 formed therein.

[0056] Sixth embodiment The sixth embodiment is shown in Figures 23 to 29. Figure 30 shows a usage form of the sixth embodiment. This holder 90 is an auxiliary device that snap-fits the hollow cylindrical portion 15, which corresponds to the handle of the fire extinguisher stick, to a holder body 91. A fire extinguisher stick is a lightweight, small, and slender tool for putting out fires that replaces conventional general fire extinguishers. This holder 90 has a cylinder 41 that serves as a gripping portion, and by remotely controlling the fire extinguisher stick fitted into the holder body 91, an inert gas or the like can be sprayed from the tip of the fire extinguisher stick connected to the holder to extinguish a fire.

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

[0058] The fitting portion 96 has a tapered surface 94 that allows the fire extinguisher stick 1 to be easily inserted through the opening 93 and fitted into the inner wall 95 . The fitting portion 96 is elastically fastened and fitted to the outer wall of the hollow cylindrical portion 15 of the fire extinguisher stick 1 with a moderate feeling.

[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 the axis lines of the two are offset from each other non-coaxially. This improves the handling operability by making it easier to elastically fit the fire extinguisher into the fitting part 96 of the holder 90 by a snap fit when using the fire extinguisher, and also improves the directional control and work operability of the inert gas etc. sprayed from the fire extinguisher during firefighting activities.

[0060] The hollow cylinder 41 has holes 44, 45 corresponding to locking holes to which one end of a long operating rod can be connected. For example, if a claw (not shown) of a one-touch button serving as a connecting member of a long operating rod 50 shown in FIG. 16B is configured to elastically fit into the holes 44, 45, the operating rod can be fixed to the cylinder 41 by this claw. This allows the fire extinguisher stick to be connected to the operating rod 50 via the holder 90. Therefore, the operating rod can be further operated to perform fire extinguishing activities using the fire extinguisher stick from a more remote location.

[0061] In addition, by connecting the cylinder 41 to an angle adjuster 56, such as that shown in Figures 18 and 19, which can adjust the inclination angle (θ) between the extension direction of the operating rod and the extension direction of the fire extinguisher stick, the spray direction of the inert gas ejected from the fire extinguisher stick can be changed. The basic usage of the holder 90 is similar to that of the first embodiment, and therefore a description thereof will be omitted.

[0062] (Example of use of embodiment) Figures 23 and 24 show an example of using the holder of the present invention when a fire breaks out on a large truck while it is moving. The fire extinguisher stick and the holder of the present invention are loaded onto the truck in advance. The fire extinguisher stick, holder, and operating rod are lightweight and small, making them easy to mount on the vehicle body. For example, if a fire breaks out on the rear brake disc of a vehicle, when the driver of the vehicle becomes aware of it through a notification from a crew member of another vehicle, the driver will immediately bring the vehicle to an emergency stop, remove the fire extinguisher stick, holder, and if necessary, the operating rod mounted on the vehicle, and carry out the fire extinguishing operation. The example of use shown in Fig. 23 shows a use example in which the holder 20 is fitted to the fire extinguishing stick 1 to perform fire extinguishing activities. Fire extinguishing activities can be performed by remote control only by the length of the holder 20 extended by the non-overlapping length with the handle 5.

[0063] The example of use shown in Figure 24 shows a use example of a fire extinguishing activity in which the holder 20, angle changer 56, and operating rod 50 shown in Figure 16C are fitted to the fire extinguishing stick 1. It can be remotely operated accurately to target the location of the fire while avoiding harsh environments such as hot air and flying sparks. This increases the probability of achieving early fire extinguishing. 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, so that by using it not only in the event of a fire in one's own vehicle but also in the event of a fire in another vehicle, it increases the possibility of being able to carry out initial fire extinguishing in an emergency, and can improve disaster prevention effectiveness as a disaster prevention auxiliary tool.
