Fire extinguisher mounting platform

Abstract

This fire extinguisher stand provides improved operability and convenience, enabling safe and easy use of unfamiliar fire extinguishers in emergency situations such as fires. [Solution] The mounting stand 10, which serves as an auxiliary device for the fire extinguisher, is equipped with a base plate having a support surface on which the fire extinguisher body 2 can be placed. The base plate has a pin 30 having a second guide hole 31 into which the nozzle 13 at the end of the fire extinguisher hose can be locked (inserted), and this pin can be fitted into a locking hole 20. A long pin that matches the size and shape of the nozzle at the end of the hose connected to the fire extinguisher body can be fitted into this second guide hole 31. As a result, at a fire scene, after releasing the safety pin 7, the fire extinguisher body 2 can be lifted from the support surface of the base plate by lifting the fixing lever 5, thus eliminating the need for manual operation to release the locking of the nozzle 13. Therefore, instead of pin, pop, and bang, the extinguishing agent can be sprayed from the nozzle in two simple steps: pin and bang.

Description

Technical Field

[0001] The present invention relates to a stand on which a fire extinguisher can be placed.

Background Art

[0002] Patent Document 1 is a device for automatically releasing the safety plug of a fire extinguisher. A unlocking portion is provided at the curved portion of the hose of the fire extinguisher. When the hose is directed towards the fire source, the unlocking portion operates around a fulcrum, the spring is released, and the safety plug pops out. Thus, in the event of a fire, when the hose is directed towards the fire source, the safety plug is automatically released, enabling the initial fire extinguishing effect to be exerted.

[0003] Also, Patent Document 2 is a safety device for a fire extinguisher. The rotating piece can be rotated by raising and lowering the hose, and an annular portion formed at the tip of the rotating piece loosely fits over the hose to lock the hose. Thus, the activation lever can be freely depressed, enabling the fire extinguisher to be smoothly activated in case of an incorrect operation.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Generally widely spread 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. The extinguishing agent is then sprayed from the nozzle. Because high-pressure gas is sprayed when the extinguishing agent is released from the nozzle, the nozzle or the hose body near the nozzle must be held with one hand, and the nozzle's direction must be adjusted to spray 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 the hose itself may slip from their palm, causing the hose to move erratically on its own. Once the hose begins to move uncontrollably, it becomes difficult to restrain it. When the hose starts to move erratically, it not only hinders the intended firefighting activity, but the extinguishing agent sprayed from the nozzle will scatter 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 to spray 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 the high-pressure gas.

[0012] Furthermore, in Patent Document 3, the applicant discloses a fire extinguisher hose in which, when the locking of the nozzle at the end of the hose is released from the locking part 30 of the fire extinguisher body at the start of firefighting, the shape of the hose body is guided straight by the inherent return and restoration action of the spring, thereby suppressing the flailing motion of the hose body.

[0013] The present invention aims to provide a fire extinguisher stand that enables the safe and easy use of unfamiliar fire extinguishers in emergency situations such as fire outbreaks. [Means for solving the problem]

[0014] The fire extinguisher mounting stand of the present invention is a stand on which a fire extinguisher body (2) can be mounted, A base plate (16) having a support surface (15) on which the fire extinguisher body can be placed. and, The aforementioned bottom plate A guide wall (17) is formed in an arc shape at the edge, It is possible to fit it into the guide hole (20) formed on the top surface of the guide wall, A nozzle (13) at the end of the fire extinguisher hose can be locked in place. 2nd Guide hole A cylindrical pin (30, 301, 302) having (31, 311, 312) and of Prepare, The pin is a replaceable pin having the second guide hole with an inner diameter into which the nozzle can be fitted. We will adopt this configuration.

[0015] According to the fire extinguisher mounting base of the present invention, after an operator releases the safety plug of the fire extinguisher body and then performs an operation of lifting the fire extinguisher body, a nozzle locking release operation is automatically performed following the operation, so that fire extinguishing activities can be carried out simply and quickly. When an operator lifts the fire extinguisher body placed on the support surface of the bottom plate, the nozzle can be simultaneously pulled out from the locking hole of the bottom plate. Therefore, the probability of realizing initial fire extinguishing with a simple operation without going through the manual locking release operation of the nozzle can be increased.

[0016] According to the fire extinguisher mounting base of the present invention, it can be easily attached or replaced to an existing general fire extinguisher or a general fire extinguisher before sale by retrofitting.

[0017] According to the fire extinguisher mounting base of the present invention, it has a guide hole capable of locking the nozzle at the hose tip of the fire extinguisher body. By replacing the pin that matches the outer diameter of the nozzle and the inner diameter of the guide hole for locking and inserting the nozzle for different forms of nozzles with various outer diameters, without replacing the bottom plate, it can be easily adapted to existing fire extinguishers with various nozzle shapes only by replacing the pins.

[0018] According to the fire extinguisher mounting base of the present invention, if a fire extinguisher equipped with the fire extinguisher hose described in Patent Document 3 is used in combination, when an operator lifts the fire extinguisher body placed on the support surface of the bottom plate, the nozzle can be simultaneously pulled out from the locking hole of the bottom plate. Therefore, at the fire scene, instead of the "pin, pump, pan" operation, the fire extinguishing agent can be ejected from the nozzle with a simple two-step operation of "pin, pan" (the pin is the operation of pulling out the safety plug, and the pan is the operation of lifting the fire extinguisher body). When ejecting, the flailing 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 realizing initial fire extinguishing can be significantly improved.

[0019] If this fire extinguisher mounting base is used, the probability of avoiding incomplete operations that are likely to occur during a fire can be increased from the time when fire extinguishers are installed inside and outside houses, factories, and other buildings. Therefore, when using a fire extinguisher, the occurrence rate of hose flailing that has occurred over the years can be significantly reduced.

[0020] This can reduce the disaster risk and pollution risk during fire extinguishing activities at the initial stage of fire extinguishing, and can significantly improve the effect of supporting the true fire extinguishing activities, especially the initial fire extinguishing activities.

Modes for Carrying Out the Invention

[0022] Hereinafter, the fire extinguisher installation base according to the embodiment of the present invention will be described based on the drawings. In addition, the same reference numerals are given to substantially the same constituent parts in a plurality of embodiments, and the description thereof is omitted.

[0023] (First Embodiment) The first embodiment of the present invention will be described based on FIGS. 1 to 6. FIGS. 1 to 3 show the fire extinguisher installation base according to the first embodiment of the present invention.

[0024] (Configuration of the Fire Extinguisher Installation Base) The fire extinguisher installation base according to the present embodiment is, as shown in FIGS. 1 to 3, an auxiliary tool for the fire extinguisher main body and is a base on which the fire extinguisher main body can be placed. The mounting base 10 includes a base plate 16 having a support surface 15 on which the fire extinguisher body 2 can be placed. The center of the upper surface of the base plate 16 has a support surface 15 on which the fire extinguisher body 2 can be placed. The support surface 15 is sized to include the bottom surface 22 of the fire extinguisher body 2, and the area around the support surface 15 on which the bottom surface 22 of the fire extinguisher body 2 can be in contact is at a flat level.

[0025] The edges of the support surface 15 have guide walls 17 that rise above the level of the support surface, and these guide walls 17 are C-shaped when viewed from above. On the upper surface of the base plate 16, both ends of the C-shape of the upward-rising guide walls 17 form mounting portions 18, and the peripheral surfaces of the mounting portions 18 have flat edge surfaces 19.

[0026] The upper edge of the base plate 16 has a guide wall 17 that is formed in an arc shape, which appears as a C shape when viewed from above. The support surface 15 is basically formed in a circular shape. The top surface of the guide wall 17 is continuous with the top surface of the mount part 18. The base plate 16 has a locking hole 20 that corresponds to a guide hole into which the nozzle 13 at the end of the fire extinguisher hose can be locked (inserted). Pins 30 (301, 302) shown in Figures 4A and 4B can be fitted into this locking hole 20.

[0027] (Pin description) Each pin 30 (301, 302) has an elongated shape and a second locking hole 31 (311, 312) that corresponds to a second guide hole that fits the size and shape of the nozzle 13 at the end of the hose connected to the fire extinguisher body 2. The pins 30 (301, 302) are cylindrical in shape and have a second locking hole opening at one end, which guides (fits into) the tip of the nozzle 13 for locking. A pin 30 is selected that has a second locking hole with a shape corresponding to the size and shape of the outer diameter of the outer wall of the locking portion of the nozzle 13. Figure 4A shows pin 301 with an inner diameter d1 of the second locking hole 311, and Figure 4B shows pin 302 with an inner diameter d2 of the second locking hole 312. Select a pin that matches the outer diameter of the nozzle locking part at the end of the hose of the fire extinguisher and fit it into the locking hole. The outer diameters of pin 301 and pin 302 are the same.

[0028] Next, Figures 5 and 6 show examples of how the fire extinguisher stand is used. (Fire extinguisher configuration) As shown in Figure 5, the fire extinguisher 1 placed on the mounting base 10 includes a fire extinguisher body 2, a body outlet 3, a safety pin 7 that blocks a passage (not shown) inside the body outlet 3, a discharge port 42 that communicates with the pressure chamber (not shown) of the body container 2 and switches the passage open when the safety pin 7 is pulled out, a fixed lever 5 and a movable lever 6 that intermittently open the passage, an indicator pressure gauge 8 that detects the pressure in the passage on the inlet side of the fixed lever 5 and the movable lever 6, and a cap 43 that fixes the indicator pressure gauge 8 to the fire extinguisher body 2.

[0029] The fire extinguisher hose 40 consists of a hose body 11 made of a flexible tubular material and a compression coil spring 41 inserted around its outer circumference. In its free state, the compression coil spring 41 has straight-line movement along its central axis, which is straight. The compression coil spring 41 has a shape that extends straight in the axial direction when in its free state. When a compressive force is applied to the free-state compression coil spring 41 in the axial direction, it can be compressed according to the magnitude of the axial force, and when the compressive force is released, it returns to its original axial length.

[0030] On the side of the fire extinguisher hose 40 that attaches to the fire extinguisher body, a body-side fastener 47 is screw-connected to the threads of the body outlet 3, and one end of the hose body 11 is inserted into the outer wall of the small-diameter cylinder of the body-side fastener 47. As shown in Figure 5, the nozzle attachment side of the fire extinguisher hose 40 has the other end of the hose body 11 inserted into the outer wall of a small-diameter cylinder (not shown) formed on the opposite side of the nozzle 13's discharge hole (not shown). The nozzle 13 is crimped and fixed to the outer wall of the other end of the hose body 11 by a fitting (not shown). As a result, one end of the compression coil spring 41 guides the other end of the hose body 11 while maintaining a free state.

[0031] When the nozzle 13 is locked in the locking hole 31 (second guide hole) of the pin 30, as shown in Figure 5, the hose body 11 bends and flexes, and the nozzle 13 connected to the hose body 11 is locked in the locking hole 31 (second guide hole). At this time, the compression coil spring 41 that guides the hose body 11 maintains a restoring force that would cause it to extend straight, while bending and flexing in accordance with the bending and flexing of the hose body 11.

[0032] Next, when firefighting is performed in the event of a fire, the operator grasps the locking lever 5 from the state shown in Figure 5, pulls out the safety pin 7 in the direction of arrow 25, and then, as shown in Figure 6, when the operator lifts the locking lever 5, the fire extinguisher body 2 moves away from the support surface 15 of the bottom plate 16 of the mounting base 10 in the direction of arrow 36, and the nozzle 13 at the tip of the hose is released from the second locking hole 31 in the direction of arrow 35 and moves away from the pin 30. When the locking from the pin 30 of the nozzle 13 is released, as shown in Figure 6, the compression coil spring 41 returns to its original position in the direction of arrow 45 due to the restoring force and extends straight, and the hose body 11, which is mechanically guided by the compression coil spring 41, also extends straight, resulting in a shape in which the hose body 11 extends in the axial direction of the main body outlet 3 in its natural state.

[0033] Therefore, the hose body 11 can spray the fire extinguishing agent along with the high-pressure gas in the direction of the nozzle 13 pointed by the operator, without the hose body 11 moving erratically. When the fire extinguisher body 2, which is placed on the support surface 15 of the base plate 16, is lifted, the nozzle 13 can be simultaneously pulled out from the second locking hole 31 of the base plate 16. Therefore, at the scene of a fire, instead of a pin-pong-bang procedure, the extinguishing agent can be sprayed from the nozzle with a simple operation without the need to manually pull out the nozzle 13 from the second locking hole 31 of the pin 30 that fits into the base plate 16 in two steps (pin-bang). This suppresses the oscillating of the hose body 11 during spraying, allowing the extinguishing agent to be sprayed accurately in the direction of the target. This significantly improves the probability of achieving initial fire suppression.

[0034] (action) According to the present invention, the fire extinguisher mounting stand of this embodiment can be used as a stand on which the fire extinguisher body is placed. The method of using a fire extinguisher with a hose spring using the fire extinguisher mounting stand of this embodiment will be explained with reference to Figures 5 and 6.

[0035] First, as shown in Figure 5, pull the safety plug 7 out of the cap 4 in the direction of arrow 25. Next, when the locking lever 5 of the operating lever of the fire extinguisher placed on the mounting stand is lifted, the hose body 11, which is fixed to the main container 2 with a metal fitting, is pulled along with the main container 2. At the same time, the nozzle 13 at the tip of the hose body is released from the second locking hole 31 of the pin 30, and the nozzle 13 separates from the hose body 11.

[0036] As shown in Figure 6, the compression coil spring 41 returns to its free state, straight and extended shape, due to the restoring force. As the shape of the compression coil spring 41 changes due to the restoring force, it follows the shape change of the hose body 11, deforming the hose body 11 into a straight and extended shape. At this time, the fire extinguisher hose 10, guided by the coil spring 41, extends straight axially relative to the body outlet 3 in the direction of arrow 45 shown in Figure 6, due to the restoring force of the spring 41.

[0037] Next, when the operator grasps the fixed lever 5 and the movable lever 6, the high-pressure gas and fire extinguishing agent inside the main container 2 are sprayed from the nozzle 13 through the main outlet 3 and the passage (not shown) of the hose body 11. At this time, the hose body 11 tends to thrash violently due to pressure fluctuations in the passage, but the compression coil spring 12 extending in the axial direction around the hose body 11 maintains its straightness through restoring force, restricting the thrashing of the hose body 11 and attempting to maintain the straight shape of the hose body. As a result, the compression coil spring 12 restricts the change in shape of the hose body, so the shape of the hose body 11 is maintained in a straight line, and the straightness of the ejection direction of the fire extinguishing agent sprayed from the nozzle 13 is ensured.

[0038] According to the fire extinguisher stand of this embodiment, when the fire extinguisher body placed on the support surface of the base plate is lifted, the hose body connected to the fire extinguisher body is pulled, and the nozzle at the end of the hose is pulled out from the locking hole in the base plate. Therefore, at the scene of a fire, the extinguishing agent or gas can be sprayed in two stages: pulling out the safety pin and lifting the operating lever, rather than three stages: pulling out the safety pin and releasing the nozzle lock and lifting the operating lever. Sensory experience: instead of three stages of "ping, pop, bang," the extinguishing agent can be sprayed from the nozzle quickly and easily in two stages: "ping" and "bang."

[0039] When used in conjunction with a fire extinguisher equipped with a fire extinguisher hose as described in Patent Document 3, the nozzle lock is automatically released by a manual lifting operation at the start of firefighting, allowing for the spraying of high-pressure gas for firefighting. In an emergency, one step of the process of unfamiliar, non-routine operation can be omitted, and the process of spraying the extinguishing agent can be quickly and easily performed. By lifting the main container from the fixing lever and gripping the movable lever and operating lever, the shape of the fire extinguisher hose is kept "straight," maintaining its straight-line shape and trajectory. 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.

[0040] Therefore, the fire extinguishing agent discharged from the nozzle is essentially ejected in the direction desired by the operator. This allows for proper operation of the hose towards the fire without erratic movement, and prevents the fire extinguishing agent from scattering into the surrounding area. As a result, even in emergencies, the nozzle direction can be properly controlled when fighting a fire at the source of the fire. This significantly improves the success rate of initial fire suppression. In the event of a fire, it becomes possible to safely and easily extinguish the fire using an unfamiliar fire extinguisher, increasing the probability of achieving initial fire suppression.

[0041] (Other embodiments) In the embodiment of the present invention, the fire extinguisher mounting stand is provided with a pin having a second locking hole, and this pin is provided so as to be detachably fitted into the locking hole of the bottom plate. However, in the present invention, the nozzle at the end of the hose may be directly fitted into the locking hole of the bottom plate without providing a pin. Furthermore, the present invention may also involve a configuration in which the pin is fitted and fixed into the locking hole of the bottom plate, rather than using a pin that is detachable from the locking hole.

[0042] The periphery of the support surface of the present invention may be formed on a plane at the same level as the plane of the support surface 15, without providing an edge. The periphery of the support surface may be partially planar in the circumferential direction. Furthermore, in the present invention, when a guide wall is provided, it may be partially provided circumferentially around the support surface of the bottom plate, or the guide wall may be in a notched shape. The bottom surface of the base plate 16 may have a fixing portion that secures it to the floor surface.

[0043] 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. The form of the fire extinguisher is not limited to the above, and the fire extinguisher mounting stand of the present invention can be applied to fire extinguishers that use a bendable hose body. The mounting stand of the present invention can, of course, also be applied to fire extinguishers that have a hose nozzle without a spring.

[0044] The fire extinguisher stand of the present invention may also have a guide wall (17) on the edge of the bottom plate. The height of the guide wall may be such that the height on the opposite side of the opening position of the guide hole (h1) is less than the height of the opening position of the locking hole (h2). The guide wall may be configured to have an inclined surface (171) whose height decreases as it moves away from the location of the hole. The guide wall may be configured to have an arc-shaped height.

[0045] The fire extinguisher mounting stand of the present invention is equipped with cylindrical pins (30, 301, 302) having second guide holes (31, 311, 312) into which the nozzle at the end of the fire extinguisher hose can be locked (inserted), and the outer walls of the pins may be made to fit into the guide hole (20). The fire extinguisher stand of the present invention may have a planar side surface (19) on the edge surface of the bottom plate at a position 90 degrees circumferentially from the position of the guide hole with respect to the center of the support surface. Herein, the planar side surface is easy to use as a side surface for aligning the stand 10 with an interior wall surface such as a column or wall of a building that partitions the space in which the stand is placed. The fire extinguisher stand of the present invention may be configured to have a joint on the bottom surface of the bottom plate that can be fixed to the floor surface.

[0046] The present invention is most effective when applied to a fire extinguisher using the aforementioned fire extinguisher mounting stand, which is equipped with a spring (41) capable of maintaining the hose body in a straight shape. In this case, the fire extinguisher is one in which the hose has a spring attached, and the spring is not limited to a coil spring, but may also be a leaf spring, and the shape of the spring is not limited. Here, "in a straight shape" generally means in a straight line, but also includes the meaning of a strictly gently curving shape. The mounting stand of the present invention can, of course, be applied to fire extinguishers using a springless hose nozzle.

[0047] 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. [Explanation of symbols]
