Description

Technical Field

[0001] The present invention relates to a fire hydrant device installed in a tunnel for storing a fire hose, a fire extinguisher, etc., and a fire extinguisher box installed in a tunnel for storing a fire extinguisher.

Background Art

[0002] Conventionally, in tunnels such as highways and motorways, a fire hydrant device is installed as an emergency facility in the tunnel. The fire hydrant device includes a fire hose with a nozzle attached to its tip and valves including a fire hydrant valve stored in a fire hydrant storage section of a housing equipped with a forward-tilting door (fire hydrant door), and, for example, two fire extinguishers are stored in a fire extinguisher storage section equipped with a fire extinguisher door. Also, the fire hydrant device is generally installed in the tunnel wall by cutting out the tunnel wall at intervals of, for example, 50 meters in the longitudinal direction of the tunnel.

[0003] By the way, in a tunnel constructed by the shield method or the like, due to the structure of the tunnel body, it is difficult to install the fire hydrant device by cutting out the tunnel wall and embedding it due to cost and labor issues. Therefore, it is necessary to install the fire hydrant device in a state where it is exposed in the monitor passage.

[0004] Also, in order to install the fire hydrant device without cutting out the tunnel wall, a wall-mounted structure has been proposed in which the fire hydrant device is attached and fixed to a pedestal installed on the tunnel wall. In this case, the pedestal is composed of a main support portion fixed to the wall surface and a posture holding member that holds the posture of the fire hydrant device (Patent Document 2).

[0005] Also, since the wall-mounted fire hydrant device has problems such as taking a lot of labor and time to attach to the tunnel wall, it is considered to adopt a so-called stationary structure in which the fire hydrant device is attached and fixed in an exposed state to a pedestal installed on the road surface of the monitor passage where installation is easy.

[0007] Incidentally, even in the case of wall-mounted or freestanding fire hydrant systems, if, for example, two fire extinguishers are stored in the fire extinguisher storage section of a housing equipped with a fire extinguisher door, when a fire breaks out and road users need to use the fire extinguishers, they will need to open the fire extinguisher door sideways (the door, which is pivotally supported on one side, rotates) to take out the fire extinguishers from the storage section and carry out firefighting. However, if the fire extinguisher door remains open after the fire extinguishers have been taken out, it creates a problem as it obstructs the passage of evacuees evacuating from the guard's passage.

[0008] This problem also applies to fire extinguisher boxes installed as emergency equipment in lower-ranked tunnels, which are categorized based on factors such as traffic volume and tunnel length.

[0009] The present invention aims to provide a fire hydrant system and a fire extinguisher box that do not obstruct the passage of security personnel and allow road users to easily retrieve fire extinguishers. [Means for solving the problem]

[0016] (Display of operation sequence of fire extinguisher door) On the upper side fire extinguisher door and the lower side fire extinguisher door, characters, figures or symbols indicating the order of operations are displayed.

[0017] (Fire extinguisher pulling structure with upper and lower integrated side fire extinguisher doors) The fire extinguisher pulling structure has a side fire extinguisher door in which the upper side fire extinguisher door and the lower side fire extinguisher door are integrated. The side fire extinguisher door has an upper pulling body and a lower pulling body divided into two upper and lower stages on the inner surface.

[0018] (Pulling mechanism of fire extinguisher pulling structure with upper and lower integrated side fire extinguisher doors) The fire extinguisher pulling structure omits the upper pulling mechanism and has only the lower pulling mechanism.

[0019] (Door handle) The side fire extinguisher door has a door handle that releases the lock with the pulling opening in response to a pulling operation.

[0020] (Display of equipment name) On the side fire extinguisher door, the character string "Fire Extinguisher" is displayed.

[0021] (Equipment name and viewing window on the front of the housing) On the front of the housing corresponding to the fire extinguisher storage part, the character string "Fire Extinguisher" written horizontally or vertically is displayed, and it has a viewing window that allows the storage state of the fire extinguisher to be visually recognized.

[0022] (Operation instructions for side fire extinguisher door) The casing features an operating manual on the front and / or side of the fire extinguisher storage compartment, guiding users through the process of removing the fire extinguisher by pulling it out.

[0023] (Fire extinguisher box) The present invention relates to a fire extinguisher box in which the housing is installed at a predetermined height above the road surface of a monitoring walkway provided along the wall of a tunnel having a road, and is located close to or in contact with the tunnel wall, It is characterized by having a fire extinguisher pull-out structure that allows the fire extinguisher, which is placed horizontally in the fire extinguisher storage section inside the casing, to be taken in and out from the side of the casing.

[0024] The details of the fire extinguisher drawer structure in the fire extinguisher box are the same as those for the fire hydrant system described above, so we will omit that explanation. [Effects of the Invention]

[0025] (Effectiveness of fire hydrant systems) According to the present invention, a fire hydrant device is provided in which a housing is installed at a predetermined height above the road surface of a monitoring walkway provided along the wall surface of a tunnel having a road, and the housing is installed in close proximity to or in contact with the tunnel wall surface, and the fire extinguisher, which is placed horizontally in the fire extinguisher storage section inside the housing, is equipped with a fire extinguisher pull-out structure that allows the fire extinguisher to be moved in and out from the side of the housing when road users use the fire extinguisher to perform firefighting activities, and the fire extinguisher can be pulled out in the direction of the side of the housing of the fire hydrant device, making it possible to take out the fire extinguisher without obstructing the passage of evacuees in the monitoring walkway in front of the housing.

[0026] (Effect of the fire extinguisher drawer structure separated into upper and lower sections on the fire extinguisher door) Furthermore, the fire extinguisher pull-out structure allows two fire extinguishers, which are placed horizontally in the fire extinguisher storage section, to be inserted into and removed from the side of the housing. The structure includes a pull-out opening formed on the side of the housing, an upper fire extinguisher storage section and a lower fire extinguisher storage section formed inside the housing corresponding to the upper and lower pull-out openings which divide the pull-out opening into upper and lower sections, an upper pull-out body located on the bottom side of the upper pull-out opening and provided to be inserted into and removed from the upper fire extinguisher storage section, and for placing one fire extinguisher horizontally so that it can be removed easily, an upper pull-out body located on the bottom side of the lower pull-out opening and provided to be inserted into and removed from the lower fire extinguisher storage section, and for placing the other fire extinguisher horizontally so that it can be removed easily, and an upper pull-out mechanism fixed to the pull-out end of the upper pull-out body that opens and closes the upper pull-out opening when the upper pull-out body is inserted and removed. The enclosure is equipped with a side fire extinguisher door, a lower side fire extinguisher door fixed to the drawer-side end of the lower drawer body which opens and closes the lower drawer opening as the lower drawer body is extended and retracted, an upper drawer mechanism which supports the upper drawer body so as to be movable in the drawer direction relative to the upper fire extinguisher storage section, and a lower drawer mechanism which supports the lower drawer body so as to be movable in the drawer direction relative to the lower fire extinguisher storage section. As a result, the two fire extinguishers housed horizontally in the upper and lower drawer bodies can be pulled out by road users by pulling the upper side fire extinguisher door or the lower side fire extinguisher door towards them (towards the side of the enclosure), extinguishing the upper or lower drawer body to an exposed position on the side of the enclosure, for example, like opening a desk drawer, and allowing the horizontally positioned fire extinguishers to be removed.

[0027] (Effects of the interlocking mechanism for the upper and lower side fire extinguisher doors) Furthermore, the fire extinguisher pull-out structure is equipped with a pull-out interlocking mechanism that pulls out the lower side fire extinguisher door in conjunction with the pull-out operation of the upper side fire extinguisher door. For example, in the pull-out interlocking mechanism, the lower outer edge of the upper side fire extinguisher door is located on the inner side of the upper edge of the lower side fire extinguisher door, and as the upper side fire extinguisher door is pulled out, the lower outer edge comes into contact with the upper inner edge, causing the lower side fire extinguisher door to be pulled out. Therefore, when the upper side fire extinguisher door is pulled out, the lower side fire extinguisher door is also pulled out in conjunction with this operation, and the upper and lower pull-out bodies are pulled out simultaneously, making it possible to remove the two fire extinguishers that are placed horizontally in each. After the upper fire extinguisher has been removed, road users can push the upper side fire extinguisher door back into the housing to make it easier to remove the lower fire extinguisher. In addition, the lower side fire extinguisher door can be pulled out independently without being interlocked with the upper side fire extinguisher door, making it possible to remove the single fire extinguisher that is placed horizontally in the lower pull-out body.

[0028] (Effect of the door handle) Furthermore, the upper side fire extinguisher door is equipped with an upper door handle that releases the lock from the upper drawer opening in response to the pull-out operation, and the lower side fire extinguisher door is equipped with a lower door handle that releases the lock from the upper side fire extinguisher door in response to the pull-out operation. Therefore, under normal circumstances, the upper side fire extinguisher door is securely locked by the upper door handle, and the lower side fire extinguisher door is securely locked by the lower door handle. When a road user wants to use the fire extinguisher, they can place their hand on the upper or lower door handle and pull it out, releasing the lock and allowing them to easily pull out the upper or lower drawer body, on which the fire extinguisher is placed horizontally, to an external position on the side of the housing.

[0029] (Effect of displaying the equipment name on the side fire extinguisher door) Furthermore, the enclosure displays the word "fire extinguisher" on its sides, including the upper and lower side fire extinguisher doors, making it easy for road users to understand that the doors for removing fire extinguishers from the fire hydrant system are located on the sides of the enclosure.

[0030] (Effect of displaying the operating sequence on the fire extinguisher door) Furthermore, the upper and lower side fire extinguisher doors are marked with letters, figures, or symbols indicating the order of operation. For example, if the upper side fire extinguisher door displays "1" and the lower side fire extinguisher door displays "2," road users will operate the door in the order of the upper side fire extinguisher door followed by the lower side fire extinguisher door, according to the numbers indicating the order. This ensures that even with two side fire extinguisher doors, users can operate them without confusion.

[0031] (Effect of a fire extinguisher pull-out structure with the side fire extinguisher door integrated into the upper and lower sections) Furthermore, the fire extinguisher pull-out structure features a side fire extinguisher door that integrates the upper and lower side fire extinguisher doors. The side fire extinguisher door is divided into two sections on its inner surface, an upper pull-out body and a lower pull-out body. Therefore, when the side fire extinguisher door is pulled out, the upper and lower pull-out bodies are pulled out together, allowing either or both of the two fire extinguishers placed horizontally inside to be removed.

[0032] (Effect of the drawer mechanism of a fire extinguisher drawer structure in which the side fire extinguisher door is integrated into the upper and lower sections) Furthermore, the fire extinguisher pull-out structure simplifies the mechanism by omitting the upper pull-out mechanism and only providing a lower pull-out mechanism.

[0033] In this case as well, the side fire extinguisher door is equipped with a door handle that releases the lock from the drawer opening in response to the drawer operation. Therefore, under normal circumstances, the side fire extinguisher door is securely locked by the door handle, and when a road user wants to use the fire extinguisher, they can place their hand on the door handle and perform the drawer operation, which releases the lock and allows the upper and lower drawer bodies, on which the fire extinguisher is placed horizontally, to be easily pulled out to an external position on the side of the housing.

[0034] Furthermore, the side fire extinguisher door displays the word "fire extinguisher," making it easy for road users to understand that the door for removing the fire extinguisher in the fire hydrant system is located on the side of the casing.

[0035] (The name of the fire extinguisher on the front of the enclosure and the effect of the viewing window) Furthermore, the casing features the word "fire extinguisher" displayed horizontally or vertically on the front of the fire extinguisher storage compartment, making it easy for road users to identify the side of the fire hydrant system where the fire extinguisher is stored. It also includes a viewing window that allows for visual confirmation of the fire extinguisher's storage status, making it easy to verify from the outside during inspections that the fire extinguisher is properly stored.

[0036] (Effect of providing instructions on how to operate the side fire extinguisher door) Furthermore, the housing has instructions on the front and / or side corresponding to the fire extinguisher storage area, guiding users on how to remove the fire extinguisher by pulling it out. This allows road users attempting to retrieve a fire extinguisher from a fire hydrant to see the instructions on the front of the housing, learn that the fire extinguisher door is on the side of the housing, and that the fire extinguisher can be removed by pulling out the side fire extinguisher door, thus enabling them to reliably pull out and remove the fire extinguisher using the side fire extinguisher door. In particular, it is commonly known that the fire extinguisher doors of conventional fire hydrant systems are provided on the front of the housing and can be freely opened horizontally. However, the side fire extinguisher door on the side of the housing according to the present invention has a unique structure that is not common knowledge. Therefore, road users can remove the fire extinguisher by pulling out the side fire extinguisher door provided on the side of the housing without confusion by following the instructions on the front of the housing.

[0037] (Effect of fire extinguisher boxes) Since the fire extinguisher box of the present invention provides the same effects as the fire hydrant device described above, a detailed explanation will be omitted. [Brief explanation of the drawing]

[0039] Embodiments of the fire hydrant system and fire extinguisher box according to the present invention will be described in detail below with reference to the drawings. However, the present invention is not limited to the following embodiments.

[0040] [Basic Concepts of the Embodiment] First, the basic concept of the embodiment will be explained. The embodiment generally relates to a fire hydrant system in which fire hydrant equipment and fire extinguishers are arranged inside a housing.

[0041] Here, "fire hydrant system" refers to a type of emergency equipment installed in tunnels on expressways and other roads that are designated as fire-fighting areas. It consists of a housing installed in the fire-fighting area containing fire hoses and other fire hydrant equipment, an electrically operated door with red indicator lights and transmitters, and fire extinguishers, and is a concept that includes fire hydrant facilities where a fire hydrant system is installed.

[0042] Furthermore, the fire hydrant system is installed exposed at a predetermined height above the road surface of the guardian's walkway, which is provided along the inner wall of the tunnel containing the road. Here, "predetermined height" refers to a height at which the fire hydrant system can be installed in close proximity to or in contact with the tunnel wall. For example, this can be achieved by attaching and fixing the housing to the upper part of a frame installed on the road surface of the guardian's walkway, or by attaching and fixing the housing to the front part of a frame installed on the tunnel wall above the road surface of the guardian's walkway, which is on the road side.

[0043] Furthermore, "framework" refers to a structure that supports objects using columns and beams, and although specific examples are not shown in the illustration, it includes concepts such as support base, foundation, base, pedestal, and base.

[0044] The fire hydrant device of this embodiment is characterized by having a fire extinguisher pull-out structure that allows a fire extinguisher, which is placed horizontally in the fire extinguisher storage section inside the housing, to be moved in and out from the side of the housing. When road users use a fire extinguisher to fight a fire, they can pull out the fire extinguisher from the side of the fire hydrant device housing without obstructing the passage of the guardian's walkway. Here, "placing the fire extinguisher horizontally" means placing the fire extinguisher on its side, which reduces the vertical storage space required for the fire extinguisher inside the housing.

[0045] The "fire extinguisher pull-out structure" is designed to individually store and pull out two fire extinguishers, corresponding to the two separate side fire extinguisher doors in this embodiment. Its structure and shape are arbitrary, but for example, it consists of an upper fire extinguisher pull-out structure and a lower fire extinguisher pull-out structure. The upper pull-out structure consists of an upper fire extinguisher storage section, an upper pull-out body, an upper side fire extinguisher door, and an upper pull-out mechanism. The lower fire extinguisher storage structure consists of a lower fire extinguisher storage section, a lower pull-out body, a lower side fire extinguisher door, and a lower pull-out mechanism.

[0046] Here, taking the upper fire extinguisher drawer structure as an example, the "upper fire extinguisher storage section" is a storage section formed on the upper side of the fire extinguisher storage section within the housing, corresponding to the upper drawer opening which is divided into upper and lower sections. The "upper drawer body" is located on the bottom side of the upper drawer opening and is installed to be easily inserted into and removed from the upper fire extinguisher storage section. The "upper side fire extinguisher door" is a fire extinguisher door fixed to the drawer-side end of the upper drawer body and opens and closes relative to the upper drawer opening as the upper drawer body is inserted and removed. In this embodiment, the "fire extinguisher door" does not refer only to this part that opens and closes, but to a structure fixed to the drawer-side end of the drawer body, and includes concepts such as the fire extinguisher drawer panel, side panel, and fire extinguisher storage section cover.

[0047] Furthermore, the "upper drawer mechanism" is a mechanism that supports the upper drawer body so that it can move freely in the pulling direction relative to the upper fire extinguisher storage section. Its structure and function are arbitrary, but for example, drawer mechanisms from office desks or document lockers can be used. In this mechanism, a guide rail fixed to the drawer body is slidably fitted into a guide rail fixed to the housing side via guide rollers. The lower fire extinguisher drawer structure is similar, simply by replacing "upper" with "lower".

[0048] The upper and lower side fire extinguisher doors are operated individually to allow road users to pull out the fire extinguishers, which are placed horizontally in each drawer, and take them out one by one. In this embodiment, however, when the upper side fire extinguisher door is pulled out, the lower side fire extinguisher door is also pulled out in conjunction with this operation, and a pull-out mechanism is provided that allows two fire extinguishers to be taken out by pulling out the upper side fire extinguisher door.

[0049] Furthermore, the upper and lower side fire extinguisher doors are marked with letters, figures, or symbols indicating the order of operation. For example, the upper side fire extinguisher door displays "1" and the lower side fire extinguisher door displays "2." These numbers guide road users, for example, in retrieving the fire extinguisher by pulling out the upper side fire extinguisher door.

[0050] Furthermore, the upper side fire extinguisher door is provided with an upper door handle, and the lower side fire extinguisher door is provided with a lower door handle. Here, the "upper door handle" is used to release the lock from the upper drawer opening in response to the drawer operation. Normally, the upper side fire extinguisher door is locked by the upper door handle, and when a road user pulls out the upper door handle, the lock is released, allowing the upper drawer body to be pulled out to an exposed position on the side of the housing, making it possible to remove the fire extinguisher.

[0051] Furthermore, the "lower door handle" releases the lock from the upper side fire extinguisher door in response to the pull-out operation. Normally, the lower side fire extinguisher door is locked to the upper side fire extinguisher door by the lower door handle. When a road user pulls out the lower door handle, the lock is released, allowing the lower drawer body to be pulled out to an exposed position on the side of the housing, enabling the fire extinguisher to be removed.

[0052] Alternatively, the side fire extinguisher door may be a single, integrated door rather than being divided into two upper and lower sections. In this case, two fire extinguishers can be removed by pulling out the single side fire extinguisher door. In this case, the pull-out mechanism may not have an upper pull-out mechanism, and may only have a lower pull-out function.

[0053] Furthermore, the word "Fire Extinguisher" is displayed vertically on the side of the housing, including the upper and lower side fire extinguisher doors, indicating to road users that the fire extinguisher doors are located on the side of the housing. The word "Fire Extinguisher" is also displayed on the front of the housing corresponding to the fire extinguisher storage area, further clarifying the location of the fire extinguisher storage in the fire hydrant system.

[0054] Furthermore, a "viewing window" is provided on the front of the housing that corresponds to the fire extinguisher storage compartment. This viewing window allows for easy external confirmation of whether the fire extinguisher is properly stored during inspections.

[0055] Furthermore, "Instructions for Operating the Fire Extinguisher" are displayed on the front and / or side of the housing corresponding to the fire extinguisher storage compartment. Here, "Instructions for Operating the Fire Extinguisher" are instructions that guide users on how to remove the fire extinguisher by pulling out the side fire extinguisher door. Road users who wish to retrieve a fire extinguisher from a fire hydrant can see the "Instructions for Operating the Fire Extinguisher" on the front of the housing, learn that the fire extinguisher door is on the side of the housing, and can easily retrieve the fire extinguisher by pulling out the side fire extinguisher door.

[0056] In particular, it is commonly known that the fire extinguisher doors of conventional fire hydrant systems are mounted on the front of the casing and can be opened horizontally. Even so, the "fire extinguisher operation instructions" on the front of the casing allow road users to easily retrieve the fire extinguisher by pulling out the side fire extinguisher door located on the side of the casing.

[0057] Furthermore, this embodiment relates to a fire extinguisher box in which a fire extinguisher is placed inside a housing. Here, "fire extinguisher box" is a type of emergency equipment installed in areas to be extinguished, such as tunnels on expressways and motorways, and is a concept that includes a fire extinguisher system in which a fire extinguisher box is installed, with a fire extinguisher and electrical equipment such as a red indicator light and a transmitter housed inside a housing installed in the area to be extinguished, and an electrical door.

[0058] In the embodiment of the fire extinguisher box, as in the case of the fire hydrant system described above, a "fire extinguisher pull-out structure" is provided that allows the fire extinguisher, which is placed horizontally in the fire extinguisher storage section inside the housing, to be taken in and out from the side of the housing.

[0059] The following describes a specific embodiment. In the specific embodiment shown below, the fire hydrant device is mounted and fixed on a stand installed on the monitoring staff walkway inside the tunnel, and the fire extinguisher storage section of the housing is provided with a fire extinguisher pull-out storage structure, and the fire extinguisher storage section is divided into upper and lower sections, with an upper fire extinguisher pull-out structure and a lower fire extinguisher pull-out structure.

[0060] [Specific details of the embodiment] We will now explain the fire hydrant system in more detail. The explanation will be divided as follows: a. Overview of fire hydrant systems b. Installation of fire hydrant system c. Installation height and slimming of fire hydrant systems d. Configuration that accommodates the miniaturization of fire hydrant systems e.

Modifications of the present invention

[0061] [a. Overview of fire hydrant systems] A more detailed explanation of the fire hydrant system equipped with a fire extinguisher pull-out structure will be provided. In this explanation, refer to Figure 1, which shows the installation state of the fire hydrant system equipped with a fire extinguisher pull-out structure in a tunnel in a longitudinal section (cross section in the longitudinal direction of the tunnel), and Figure 2, which shows the installation state of the fire hydrant system in Figure 1 in a cross section of the tunnel.

[0062] In the explanation of Figures 1 and 2, the X, Y, and Z directions are mutually orthogonal. Specifically, when viewing the front of the fire hydrant device 10, the X direction is the left-right direction, the Y direction is the up-down direction, and the Z direction is the front-back direction. Furthermore, in the X direction, the +X side is the right side and the -X side is the left side; in the Y direction, the +Y side is the upper side and the -Y side is the lower side; and in the Z direction, the +Z side is the front side and the -Z side is the rear side. This aspect of the X, Y, and Z directions is the same in Figures 3 to 22, which represent embodiments of the present invention.

[0063] As shown in Figure 1, the housing of the fire hydrant device 10 in this embodiment is divided into a first housing 11a and a second housing 11b. A decorative frame 13a is attached to the front of the first housing 11a. The door opening of the decorative frame 13a is divided into upper and lower sections. A forward-tilting door 12, which functions as a fire hydrant door, is positioned on the lower side of the door opening and opens downward by a hinge 12a. A maintenance door 14, which opens upward by a hinge 14a, is positioned on the upper side of the door opening. The storage section for fire hydrant equipment, which is inside the first housing 11a, houses predetermined fire hydrant equipment, including fire hoses and valves such as fire hydrant valves.

[0064] A decorative frame 13b is attached to the front of the second enclosure 11b. A door opening is provided on the upper side of the decorative frame 13b, and an electrical door 18 that opens downward by a hinge 18a is positioned in the door opening. The electrical door 18 is equipped with electrical equipment such as a red indicator light 22, a transmitter 24, and an answer lamp 25, and a telephone jack is provided on the inside.

[0065] The red indicator light 22 is always illuminated, allowing the location of the fire hydrant device 10 to be identified from a distance. When a fire occurs and the transmitter 24 is pressed, turning on the push-button switch, a transmission signal is sent, and a fire alarm is output from the disaster prevention receiving panel installed in the electrical room or elsewhere that receives this signal. The fire hydrant device 10 receives a response signal from the disaster prevention receiving panel, causing the red indicator light 22 to flash and the response lamp 25 to light up.

[0066] The inside of the second enclosure 11b is a fire extinguisher storage area, and on the left side of the second enclosure 11b, which is close to the fire extinguisher storage area, there are two separate upper and lower side fire extinguisher doors 16(16-1) and 16(16-2), as shown in Figure 2. The upper side fire extinguisher door 16(16-1) is equipped with an upper door handle 1611 and an operation sequence indicator 1615 consisting of the number (Arabic numeral) "1" enclosed in a circle. The lower side fire extinguisher door 16(16-2) is equipped with a lower door handle 1612 and an operation sequence indicator 1616 consisting of the number "2" enclosed in a circle. Note that the operation sequence indicators 1615 and 1616 may be other than Arabic numerals, such as the English letters (Roman letters) "A" and "B" or the Roman numerals "I" and "II".

[0067] The upper side fire extinguisher door 16(16-1) can be pulled out in an exposed state, allowing access to a fire extinguisher stored in the upper part of the fire extinguisher storage compartment, by a road user placing their hand on the upper door handle 1611 and pulling it forward (sideways), thereby releasing the latch. The lower side fire extinguisher door 16(16-2) can be pulled out in an exposed state, allowing access to another fire extinguisher stored in the lower part of the fire extinguisher storage compartment, by a road user placing their hand on the lower door handle 1612 and pulling it forward (sideways), thereby releasing the latch. In this embodiment, when the upper side fire extinguisher door 16(16-1) is pulled out, the lower side fire extinguisher door 16(16-2) is pulled out in conjunction with it, thanks to an interlocking pull-out mechanism.

[0068] Furthermore, on the side of the housing above the upper side fire extinguisher door 16 (16-1), there is a device name display 1613 with the word "fire extinguisher" written vertically, and an operation instruction sheet 1614 which shows instructions for pulling out and removing the fire extinguisher using diagrams and other visuals.

[0069] Furthermore, as shown in Figure 1, the decorative frame 13b corresponding to the fire hydrant storage section on the left side of the second housing 11b is provided with a device name display 1613 with the word "fire extinguisher" written horizontally, the same operation instructions 1614 as on the side of the housing in Figure 2, and a viewing window 19. The viewing window 19 allows the presence or absence of a fire extinguisher to be confirmed from the outside.

[0070] [b. Installation of fire hydrant systems] The installation of fire hydrant equipment inside the tunnel will be explained in more detail. As shown in Figures 1 and 2, a road 15 is constructed in the longitudinal direction (left-right direction) of the tunnel at the bottom of the cylindrical (circular cross-section) tunnel structure constructed by the shield tunneling method, and a monitoring walkway 35 is constructed at a predetermined height relative to the road 15 on the lower side of the tunnel wall 17 along the rear side of the road 15.

[0071] Because it is difficult to cut out a box in the tunnel wall 17 constructed using the shield tunneling method to install the fire hydrant device 10, a support frame 30 is installed on the road surface of the monitoring walkway 35, close to the tunnel wall 17, and the connected first housing 11a and second housing 11b are attached and fixed onto the support frame 30 to install the fire hydrant device 10. Here, the height H1 of the support frame 30 is set so that the height from the road surface of the monitoring walkway 35 to the transmitter 24 placed on the fire hydrant device 10 falls within the legally stipulated range of 800 mm to 1500 mm.

[0072] Furthermore, as shown in Figure 2, the frame 30 of this embodiment has a side shape that is an inverted trapezoid with the top side longer than the bottom side, and the rear side is an inclined surface that slopes diagonally downward along the curved shape of the tunnel wall 17. The upper end surface of the frame 30 is to which the first housing 11a and the second housing 11b, to which the fire hydrant device 10 is connected, are attached and fixed. In addition, a water supply pipe 48 that rises up from inside the duct below the road surface of the monitoring walkway 35 through the frame 30 is connected to the fire hydrant device 10.

[0073] [c. Installation height and slimming of fire hydrant systems] The installation height and thinning of the fire hydrant system will be explained in more detail. For this explanation, please refer to Figure 3, an explanatory diagram that schematically shows the installation state of the fire hydrant system in the tunnel cross-section.

[0074] In this embodiment, in order to reduce the constraint on the width of the passage due to the protrusion (overhang) of the fire hydrant device 10, which is installed on the road surface of the guardian passage 35 by the support frame 30, from the tunnel wall 17, the installation height of the fire hydrant device 10 is optimized, and the fire hydrant device 10 is made as thin as possible.

[0075] First, since the installation height of the fire hydrant device 10 is determined by the support frame 30, we will explain in more detail how to optimize the height H1 of the support frame 30. The tunnel wall 17 on which the fire hydrant device 10 is installed has a circular cross-section. In Figure 3(A), the height H1 of the support frame 30 is set such that the horizontal centerline SL2 of the housing of the fire hydrant device 10, which is installed on the monitoring staff passage 35, is as close as possible to the horizontal tunnel centerline SL1 from the tunnel center (center of the circular cross-section) P.

[0076] In this case, the closer the housing centerline SL2 is to the tunnel centerline SL1, the less the fire hydrant device 10 protrudes from the tunnel wall 17.

[0077] Figure 3(B) shows the case where the height H1 of the support frame 30 is set so that the centerline SL2 of the housing coincides with the centerline SL1 of the tunnel. In this case, the degree to which the fire hydrant device 10 protrudes from the tunnel wall 17 can be minimized. However, the height H1 of the support frame 30 should be adjusted within the limits possible, taking into account the removal of fire extinguishers, etc.

[0078] Next, the thinning of the fire hydrant device 10 will be explained in more detail. The largest component in the fire hydrant device 10 in the front-to-back direction is the fire extinguisher housed in the second housing 11b. If the width (thickness in the front-to-back direction) of the fire hydrant device is the minimum value that the fire extinguisher can accommodate in the second housing 11b, then the fire hydrant device 10 can be made thinner. Therefore, the width of the fire hydrant device 10 is set to a predetermined width corresponding to the outer diameter of the fire extinguisher housed in the second housing 11b.

[0079] The outer diameter of a fire extinguisher is approximately 150-160 mm. If a gap is secured so that the stored fire extinguisher does not come into contact with the second housing 11b, the minimum width of the fire hydrant device 10 will be, for example, within a range of approximately 180-200 mm, and the width of the fire hydrant device 10 will be set to a predetermined width within that range. In contrast, the width of a conventional fire hydrant device 10, which is installed by cutting out a box in the wall of a tunnel structure, is approximately 300 mm. Therefore, the width of the fire hydrant device 10 in this embodiment can be reduced to 2 / 3 or less of the conventional width, and the fire hydrant device 10 can be made thinner.

[0080] [d. Configuration adapted to the miniaturization of fire hydrant systems] If the fire hydrant device 10 is made thinner to a predetermined width of approximately 180 to 200 mm, corresponding to the outer diameter of the fire extinguisher, it becomes difficult to store a fire extinguishing hose of a predetermined length, such as a 30 m shape-retaining hose, in the first housing 11a in an inward-curled state, as in conventional fire hydrant devices. Therefore, in this embodiment, by increasing the width (width in the left-right direction) of the first housing 11a, it becomes possible to store a shape-retaining hose of the same predetermined length as in conventional devices in an inward-curled state.

[0081] [e. Structure of a fire hydrant system equipped with a side fire extinguisher door] The structure of a fire hydrant system equipped with a side fire extinguisher door will be described in more detail. In this description, the internal structure of the fire hydrant system will be shown from the front with the front-sloping door open, Figure 5 will be shown in plan, Figure 6 will be shown from the right side, and Figure 7 will be shown on the side (left side) of the fire hydrant system where the fire extinguisher is stored. Of these, Figure 5 is the cross-section shown by the cutting line aa in Figure 4, and Figure 6 is the cross-section shown by the cutting line bb in Figure 4. Note that the front-sloping door 12 in Figure 6 is the side of the door in Figure 4.

[0082] (e1. Structure of the first enclosure) The structure of the first housing 11a will now be explained in more detail. The interior of the first housing 11a, which houses the fire hydrant equipment, is divided into a valve storage section 50a and a hose storage section 50b. In the valve storage section 50a, a water supply pipe 48 is drawn in from below through the frame 30 and connected to a water tap 52. The water supply pipe 48 also branches downward, and a fire hydrant valve 54 and an automatic pressure regulating valve 56 are provided at the branch end, followed by a fire extinguishing hose 60 using a shape-retaining hose.

[0083] The fire hydrant valve 54 is opened and closed by a fire hydrant valve opening / closing lever 58. When the fire hydrant valve opening / closing lever 58 is opened or closed, the fire hydrant valve 54 is remotely opened and closed by a known wire linkage mechanism. When the fire hydrant valve opening / closing lever 58 is opened or closed, a pump activation interlocking switch located in the control box is turned on or off. In addition, a pump activation switch 64 for use by the fire brigade is located to the upper right of the water tap 52.

[0084] A hose storage frame 62 is provided in the hose storage section 50b, and the fire extinguishing hose 60, which is pulled in from below, is stored in a clockwise or counterclockwise inward-curved state. Here, the hose storage frame 62 has been widened to accommodate the increased width of the first housing 11a due to the thinning of the fire extinguishing device 10, and it is possible to store the same predetermined length of fire extinguishing hose 60 with fewer turns compared to conventional fire extinguishing devices. In addition, a nozzle 68 is attached to the end of the fire extinguishing hose 60 that is pulled out through the hose guide 66, and the nozzle 68 is detachably held in the nozzle holder 70.

[0085] Furthermore, as shown in Figure 6, a cable rack 49 is provided at the top of the hose storage section 50b to route cables drawn in from outside the first housing 11a, for example, cables raised through the support frame 30, to the second housing 11b side. A cable passage opening is provided in the partition wall of the first housing 11a opposite the left end of the cable rack 49.

[0086] (e2. Structure of the second enclosure) The structure of the electrical equipment placement side of the second housing 11b will now be described in more detail. As shown in Figures 4 and 5, the interior of the second housing 11b is a fire extinguisher storage section 50c, and an electrical equipment door 18 that opens downward by a hinge 18a is placed in the door opening on the upper front side of the second housing 11b, and a red indicator light 22, a transmitter 24, a telephone jack 28, and an answer lamp 25 are arranged on the electrical equipment door 18 from right to left, with the telephone jack 28 located on the inside of the electrical equipment door 18.

[0087] Here, among the electrical equipment, the largest in the front-to-back direction within the fire extinguisher storage section 50c, which is located inside the second housing 11b, is the red indicator light 22, which measures approximately 120 mm. Therefore, even if the fire hydrant device 10 is made thinner to a predetermined width of approximately 180 to 200 mm, it is possible to arrange the electrical equipment while still securing space for the cables pulled in from the first housing 11a.

[0088] Furthermore, terminal boxes 26a and 26b are arranged horizontally on the rear surface of the interior of the second enclosure 11b, which faces the electrical door 18. Each terminal box 26a and 26b consists of a box body and a lid, and when placed in the second enclosure 11b, its dimensions (height (top and bottom) x width (left and right) x depth (front and back)) are approximately 140mm x 220mm x 80mm.

[0089] Therefore, even if the fire hydrant device 10 is made thinner to a predetermined width in the range of approximately 180 to 200 mm, the depth (front to back) of the terminal boxes 26a and 26b is approximately 80 mm, so sufficient space is secured inside the second housing 11b to accommodate the terminal boxes 26a and 26b.

[0090] (e3. Fire extinguisher storage area) As shown in Figures 4 and 5, two fire extinguishers 72 with an outer diameter of approximately 150-160 mm are stored horizontally in two layers, upper and lower, in the fire extinguisher storage section 50c inside the second housing 11b, using a fire extinguisher pull-out structure. Furthermore, as mentioned above, in order to make the fire hydrant device 10 thinner, the width of the fire hydrant device 10 is a predetermined width in the range of 180-200 mm, corresponding to the outer diameter of the fire extinguishers 72. A gap of approximately 15-25 mm is secured in front of and behind the stored fire extinguishers 72, allowing the fire extinguishers 72 to be stored without contacting the second housing 11b.

[0091] As shown in Figure 7, on the left side of the second housing 11b near the fire extinguisher storage section 50c, similar to Figure 2, an upper side fire extinguisher door 16 (16-1) is positioned in the upper pull-out opening 34 (34-1) so as to be able to be pulled out towards the front, and a lower side fire extinguisher door 16 (16-2) is positioned in the lower pull-out opening 34 (34-2) so as to be able to be pulled out towards the front. An upper door handle 1611 and a lower door handle 1612 are provided on the door surface, and operation sequence indicators 1615 and 1616 are also provided. In addition, the equipment name 1613, which is written horizontally as "fire extinguisher", and an operation instruction 1614 are provided on the side of the housing above the door.

[0092] As shown in Figure 4, the upper drawer body 32(32-1) of the upper fire extinguisher pull-out structure, which is fixed to the inside of the upper side fire extinguisher door 16(16-1), and the lower drawer body 32(32-2) of the lower fire extinguisher pull-out structure, which is fixed to the inside of the lower side fire extinguisher door 16(16-2), each have a fire extinguisher 72 placed horizontally so that it can be easily removed. For example, by pulling out the upper side fire extinguisher door 16(16-1) using the upper door handle 1611, the upper drawer body 32(32-1) is pulled out to the side, as shown by the dashed line in Figure 5, and the fire extinguisher 72 can be removed.

[0093] [f. Fire extinguisher drawer structure] The fire extinguisher pull-out structure will be explained in more detail. In this explanation, refer to Figure 8, which shows the pull-out body of the fire extinguisher pull-out structure removed; Figure 9, which shows the detailed structure of the upper pull-out body; Figure 10, which shows the fire extinguisher used in this embodiment; Figure 11, which shows the housing side of the fire extinguisher pull-out structure removed and in operation; Figure 12, which shows the lower pull-out mechanism of the fire extinguisher pull-out structure removed and in operation; Figure 13, which shows the fire hydrant device in the state of fire extinguisher storage with the side fire extinguisher door closed; Figure 14, which shows the pull-out operation of the lower side pull-out door linked to the pull-out operation of the upper side fire extinguisher door; and Figure 15, which shows the pull-out operation of the lower side fire extinguisher door.

[0094] Figures 8(A) and 8(B) show the structure of the upper and lower fire extinguisher pull-out structures, respectively, and Figures 9(A), 9(B), 9(C), 9(D), and 9(E) show the side, rear, front, rear, and enlarged cross-section of the fire extinguisher pull-out structure, as well as the cutting line dd in Figure 9(A). Figures 11(A), 9(B), 11(C), and 11(D) show the front, side, and plan views of the housing side of the fire extinguisher pull-out structure, as well as an enlarged view of section A of the housing guide rail.

[0095] The fire extinguisher pull-out structure allows road users to pull out fire extinguishers stored horizontally in two tiers, upper and lower, in the fire extinguisher storage section of the second housing 11b, using the upper side fire extinguisher door 16(16-1) and the lower side fire extinguisher door 16(16-2). The structure and mechanism are arbitrary, but for example, it may consist of an upper fire extinguisher pull-out structure and a lower fire extinguisher pull-out structure, and the upper fire extinguisher pull-out structure and the lower fire extinguisher pull-out structure may each consist of a pull-out side structure and a housing side structure.

[0096] (f1. Structure of the drawer side of the upper fire extinguisher drawer structure) The structure of the drawer side of the upper fire extinguisher drawer structure will be explained in more detail. The drawer side of the upper fire extinguisher drawer structure is a structure for inserting and removing the fire extinguisher into and out of the upper fire extinguisher storage section of the housing. Its shape and structure are arbitrary, but for example, as shown in Figures 8(A) and 9, it is composed of an upper side fire extinguisher door 16 (16-1) and an upper drawer body 32 (32-1).

[0097] The upper drawer body 32 (32-1) is used to place the fire extinguisher 72 horizontally in the upper fire extinguisher storage section and to move it to the outside on the side of the housing. Its structure and shape are arbitrary, but for example, one end of the stand 38 (38-1) is fixed in a cantilevered manner to the lower inside of the upper side fire extinguisher door 16 (16-1).

[0098] The stand 38(38-1) is for placing the fire extinguisher horizontally. To hold the horizontally placed fire extinguisher 72, a support frame 3810 made of a metal rod or the like rises from the depth side of the stand 38(38-1) to the center of the side that is the rear side of the fire hydrant device 10. In addition, a front stopper 3811 made of an elastic material such as rubber is provided on the plate surface closer to the door side, and a side stopper 3812 is provided on the plate surface closer to the side that is the fire extinguisher removal side (the front side of the fire hydrant device 10).

[0099] The main body guide rails 36(36-1) of the upper drawer mechanism are fixed to the outer sides of the side panels on both sides of the base plate 38(38-1). As shown in Figure 9(E), which is an enlarged view of the cross section of the cutting line dd in Figure 9(A), the main body guide rails 36(36-1) have rectangular cross-section rail protrusions 3610 positioned on the outer side of the side panels of the base plate 38(38-1). In addition, a roller 40 is provided at the rear (right) end of the main body guide rails 36(36-1), and a stopper piece 3611 with an inclined surface that is raised on the front (left) side is formed above the roller 40.

[0100] The upper side fire extinguisher door 16 (16-1) is provided with an upper door handle 1611 and an operation sequence indicator 1615. The upper door handle 1611 has a latch claw 1617 facing upward on the back side of the door. When the upper door handle 1611 is pulled forward, the latch claw 1617 retracts, releasing the door lock on the upper pull-out opening on the side of the housing, allowing it to be pulled out.

[0101] Furthermore, a contact piece 1618, which is bent downwards from the inside, is integrally formed at the lower end of the upper side fire extinguisher door 16(16-1), and the contact piece 1618 is located on the inside of the upper end of the lower side fire extinguisher door 16(16-2) as shown in Figure 8(B). Therefore, when the upper side fire extinguisher door 16(16-1) is pulled out, the contact piece 1618 comes into contact with the inside of the upper end of the lower side fire extinguisher door 16(16-2), creating a pull-out interlocking structure in which the lower side fire extinguisher door 16(16-2) is pulled out in conjunction with the pull-out operation of the upper side fire extinguisher door 16(16-1).

[0102] (f2. Structure of the pull-out side of the lower fire extinguisher pull-out mechanism) The structure of the drawer side of the lower fire extinguisher drawer structure will be explained in more detail. The drawer side of the lower fire extinguisher drawer structure is a structure for inserting and removing the fire extinguisher into and out of the lower fire extinguisher storage section of the housing. Its shape and structure are arbitrary, but for example, as shown in Figure 8(B), it is composed of a lower side fire extinguisher door 16 (16-2) and a lower drawer body 32 (32-2).

[0103] The lower drawer body 32 (32-2) is used to place the fire extinguisher 72 horizontally in the lower fire extinguisher storage section and to move it to the outside on the side of the housing, with one end of the stand 38 (38-2) fixed in a cantilevered manner to the lower inside of the lower side fire extinguisher door 16 (16-2).

[0104] The stand 38(38-2) is used to support the fire extinguisher in a horizontal position. To hold the fire extinguisher 72 in this horizontal position, a support frame 3810 made of a metal rod or the like extends from the depth side of the stand 38(38-2) to the center of the side that is the rear side of the fire hydrant device 10. Additionally, a front stopper 3811 made of an elastic material such as rubber is provided on the surface used on the door side, and a side stopper 3812 is provided on the surface of the plate closest to the side where the fire extinguisher can be removed (the front side of the fire hydrant device 10).

[0105] The main body guide rails 36(36-2) of the lower drawer mechanism are fixed to the outer sides of the side panels on both sides of the base 38(38-2). The main body guide rails 36(36-2) have rectangular cross-section rail protrusions 3610 positioned on the outer side of the side panels of the base 38(38-2). In addition, a roller 40 is provided at the rear (right) end of the main body guide rails 36(36-2), and a stopper piece 3611 with an inclined surface that is raised on the front (left) side is formed above the roller 40.

[0106] The lower side fire extinguisher door 16(16-2) is provided with a lower door handle 1612. The lower door handle 1612 has a latch claw 1619 facing upward on the back side of the door. When the lower door handle 1612 is pulled forward, the latch claw 1619 retracts, releasing the contact between the lower end contact piece 1618 of the upper side fire extinguisher door 16(16-1) shown in Figure 8(A) and the inside of the door, allowing it to be pulled out.

[0107] (f3. Fire extinguisher) As shown in Figures 8(A) and 8(B), the fire extinguisher 72, which is placed horizontally in the upper drawer body 32 (32-1) and the lower drawer body 32 (32-2), has an opening lever 7211 and a locking lever 7212 on the top of the fire extinguisher body 7210, as shown in Figure 10, and the opening lever 7211 is locked with a safety pin 7213. In addition, a nozzle 7215 is attached to the end of a hose 7214 connected to the top of the fire extinguisher body 7210. The fire extinguisher 72 is, for example, known as a No. 20 fire extinguisher, and the fire extinguisher body 7210 contains, for example, 6 kg of ABC powder fire extinguishing agent, with dimensions of approximately 200 mm x 600 mm and a weight of about 10 kg.

[0108] When a road user retrieves such a fire extinguisher 72 from a horizontal position, they will grasp the fixing lever 7212 to remove it. To facilitate the removal of the horizontally placed fire extinguisher 72, a handle 74 is secured to the center of the body of the fire extinguisher 7210 with two bands 76. The fixing structure of the handle 74 to the fire extinguisher body 7210 is arbitrary and includes cases where it is fixed by appropriate methods other than bands 76, such as adhesive. Therefore, by holding both the fixing lever 7212 and the handle 74, road users can easily retrieve the fire extinguisher 72 even when it is lying horizontally.

[0109] (f4. Structure of the enclosure) The structure of the housing side of the fire extinguisher pull-out structure will be explained in more detail. The housing side of the fire extinguisher pull-out structure supports the upper pull-out body 32 (32-1) and the lower pull-out body 32 (32-2) so that they can be pulled out freely within the housing. Its shape and structure are arbitrary, but for example, as shown in Figure 11, the fire extinguisher storage section 50c inside the second housing 11b is divided into an upper fire extinguisher storage section 5010 having an upper pull-out opening 34 (34-1) and a lower fire extinguisher storage section 5020 having a lower pull-out opening 34 (34-2). Upper housing guide rails 42 (42-1) are fixed to the inner surfaces on both sides of the upper fire extinguisher storage section 5010, and lower housing guide rails 42 (42-2) are fixed to the bottom corners on both sides of the lower fire extinguisher storage section 5020.

[0110] The upper housing guide rail 42(42-1) and the lower housing guide rail 42(42-2) have a predetermined length that is the same as or longer than the main body guide rails 36(36-1) and 36(36-2) of the upper drawer body 32(32-1) and the lower drawer body 32(32-2) shown in Figure 8. Furthermore, the upper housing guide rail 42(42-1) and the lower housing guide rail 42(42-2) are U-shaped frame plate members that open laterally, as shown in Figure 11(D), which is an enlargement of part A in Figure 11(A), and the roller 40 positioned on the tip side of the corresponding main body guide rail 36(36-2) shown in Figure 8 will roll inside the U-shaped frame plate member.

[0111] Furthermore, the upper housing guide rail 42(42-1) and the lower housing guide rail 42(42-2) have openings 4210 that widen at the top on the corresponding upper drawer opening 34(34-1) side and lower drawer opening 34(34-2) side, respectively, so that the rollers 40 at the ends of the main body guide rails 36(36-1) and 36(36-2) shown in Figure 8 can be inserted into the rails from diagonally above. In addition, a stopper 46 is fixed to the upper side of the opening 4210 of the upper housing guide rail 42(42-1) and the lower housing guide rail 42(42-2) with a predetermined gap between them, so that when the main body guide rails 36(36-1) and 36(36-2) fitted into the upper housing guide rail 42(42-1) and the lower housing guide rail 42(42-2) are pulled out, the stopper piece 3611 comes into contact with them and prevents them from coming out.

[0112] Furthermore, rollers 44 are positioned below the openings 4210 of the upper housing guide rail 42(42-1) and the lower housing guide rail 42(42-2). The upper side of the rollers 44 extends inward beyond the bottom surface of the upper housing guide rail 42(42-1) and the lower housing guide rail 42(42-2), allowing the lower surfaces of the rail protrusions 3610 of the main body guide rails 36(36-1) and 36(36-2), which are inserted into the upper housing guide rail 42(42-1) and the lower housing guide rail 42(42-2), to move while resting on the rollers 44.

[0113] (f5.Drawer mechanism) The drawer mechanism in the fire extinguisher drawer structure will be explained in more detail. The drawer mechanism is divided into an upper drawer mechanism and a lower drawer mechanism. In this explanation, refer to Figure 12, which shows the lower drawer mechanism of the fire extinguisher drawer structure removed and in operation. Figure 12(A) shows the drawer side removed, Figure 12(B) shows the initial state with the drawer side fitted or fully drawn out, Figure 12(C) shows the drawer side partially drawn out, and Figure 12(D) shows the drawer side closed. In Figures 12(B) to (D), the parts where the guide rails overlap are shown in a transparent view.

[0114] As shown in Figure 12, the lower drawer mechanism consists of the housing guide rail 36(36-2) of the lower drawer body 32(32-2) shown in Figure 8(B) and the lower housing guide rail 42(42-2) shown in Figure 11. Of course, it also includes rollers 40, 44 and a stopper 46.

[0115] When storing the lower drawer body 32(32-2) in the lower fire extinguisher storage section 5020 on the housing side, as shown in Figure 12(A), the worker aligns the roller 40 at the tip of the drawer guide rail 36(36-2) provided on the lower drawer body 32(32-2) side with the opening 4210 of the lower housing guide rail 42(42-2), and inserts the main body guide rail 36(36-2) into the lower housing guide rail 42(42-2) with the main body guide rail 36(36-2) angled downwards. At this time, the stopper piece 3611 of the drawer guide rail 36(36-2) is inserted so that it passes over the stopper 46 on the housing side.

[0116] As a result, as shown in Figure 12(B), the roller 40 of the main body guide rail 36(36-2) enters the lower housing guide rail 42(42-2), the roller 44 contacts the underside of the rail projection 3610 of the main body guide rail 36(36-2), and the stopper piece 3611 abuts against the stopper 46, preventing it from coming out. This state represents the position where the lower drawer body 32(32-2) is pulled out as far as it will be from the housing side.

[0117] Next, when the lower side fire extinguisher door 16 (16-2) is pushed in, as shown in Figure 12(C), the rolling of the rollers 40 and 44 causes the main body guide rail 36 (36-2) to move smoothly relative to the lower housing guide rail 42 (42-2), and as shown in Figure 12(D), the lower drawer body 32 (32-2) can move to a position where it is fully stored in the lower fire extinguisher storage section 5020.

[0118] Furthermore, the upper drawer mechanism consists of the housing guide rail 36(36-1) of the upper drawer body 32(32-1) shown in Figure 8(A) and the upper housing guide rail 42(42-1) shown in Figure 11. Its operation is the same as that of the lower drawer mechanism shown in Figure 12, so its explanation will be omitted.

[0119] (f6. Pulling out the fire extinguisher) The operation of pulling out the fire extinguisher using the fire extinguisher pull-out structure will be explained in more detail. In this explanation, refer to Figure 13, which shows the fire extinguisher stored with the side fire extinguisher door closed; Figure 14, which shows the pulling out operation of the lower side fire extinguisher door in conjunction with the pulling out operation of the upper side fire extinguisher door; and Figure 15, which shows the pulling out operation of the lower side fire extinguisher door.

[0120] As shown in Figure 13, under normal circumstances, the upper side fire extinguisher door 16(16-1) and the lower side fire extinguisher door 16(16-2) of the fire hydrant device 10 are locked in the closed position. When a road user wants to use a fire extinguisher, the lock is released by pulling the upper door handle 1611 of the upper side fire extinguisher door 16(16-1) towards the user (-X direction) according to the number "1" on the operation sequence indicator 1615. As shown in Figure 14, the upper drawer body 32(32-1) on which the fire extinguisher 72 is placed horizontally is then pulled outwards from the upper drawer opening 34(34-1).

[0121] At this time, the contact piece 1618 formed at the lower end of the upper side fire extinguisher door 16(16-1) shown in Figure 8(A) is in contact with the inner surface of the upper end of the lower side fire extinguisher door 16(16-2). As a result, the lower side fire extinguisher door 16(16-2) also starts to operate in conjunction with the pulling operation of the upper side fire extinguisher door 16(16-1). When both the upper drawer body 32(32-1) and the lower drawer body 32(32-2) are pulled out from their corresponding upper drawer openings 34(34-1) and lower drawer openings 34(34-2), the two horizontally placed fire extinguishers 72 become removable.

[0122] For road users to retrieve the fire extinguisher 72, for example, they can easily and quickly remove it by holding the fixing lever 7212 (see Figure 10) and handle 74 of the fire extinguisher 72, which is placed horizontally in the upper drawer body 32 (32-1), with both hands and lifting it towards them.

[0123] Next, when a road user wants to take out the fire extinguisher 72 from the lower drawer body 32 (32-2), the upper drawer body 32 (32-1) gets in the way. For example, the upper side fire extinguisher door 16 (16-1) is pushed in to close it, and the fire extinguisher 72, which is placed horizontally in the lower drawer body 32 (32-2), can be easily and quickly removed by holding the fixing lever 7212 (see Figure 10) and handle 74 of the fire extinguisher 72 with both hands and lifting it towards the user.

[0124] Furthermore, since the fire extinguisher 72 can be pulled out from the outside of the side of the fire hydrant device 10's casing, the monitoring staff passage 35 in the front direction of the casing, through which evacuees pass, is not restricted, and the fire extinguisher 72 can be pulled out and removed without obstructing passage in the monitoring staff passage 35.

[0125] Figure 15 shows the case where the upper side fire extinguisher door 16 (16-1) is closed and a road user operates the lower side fire extinguisher door 16 (16-2). By pulling the lower door handle 1612 towards the user (-X direction), the lock on the lower end of the upper side fire extinguisher door 16 (16-2) is released, and the lower drawer body 32 (32-2), on which the fire extinguisher 72 is placed horizontally, is pulled outwards independently from the lower drawer opening 34 (34-2).

[0126] In this case, since the upper side fire extinguisher door 16 (16-1) is in the closed position, the fire extinguisher 72, which is placed horizontally in the lower drawer body 32 (32-2), can be easily and quickly removed by holding the fixing lever 7212 (see Figure 10) and handle 74 of the fire extinguisher 72 with both hands and lifting it towards the user, without being obstructed by the upper drawer body 32 (32-1).

[0127] [g. Fire extinguisher drawer structure with integrated upper and lower side fire extinguisher doors] A fire extinguisher pull-out structure with an integrated upper and lower side fire extinguisher door will be described in more detail. In this description, refer to Figure 16, which shows a fire hydrant device with a fire extinguisher pull-out structure with an integrated upper and lower side fire extinguisher door; Figure 17, which shows the pull-out body side of the fire extinguisher pull-out structure from Figure 16; and Figure 18, which shows the fire extinguisher pull-out operation in the fire hydrant device from Figure 16.

[0128] In the fire extinguisher drawer structure shown in Figure 16, a side fire extinguisher door 16, which is integrated without being divided into upper and lower sections, is provided on the side of the second housing 11b and can be freely pulled out. Inside the side fire extinguisher door 16, as shown in Figure 17, an upper drawer body 32 (32-1) and a lower drawer body 32 (32-2) are provided, divided into upper and lower sections. The right end, which is the depth side, is connected vertically by a support member 1620, and two fire extinguishers 72 are placed horizontally in the upper and lower sections.

[0129] The details of the upper and lower fire extinguisher pull-out structures in this embodiment are the same as those of the embodiments shown in Figures 8 to 12, except for the side fire extinguisher door 16 which is integrated vertically. Therefore, the same reference numerals are used and their descriptions are omitted.

[0130] In the fire hydrant device equipped with the fire extinguisher pull-out structure of this embodiment, when a road user wants to use a fire extinguisher, the lock is released by pulling the door handle 1611 of the side fire extinguisher door 16 toward the user (-X direction). As shown in Figure 18, the upper drawer body 32(32-1) and the lower drawer body 32(32-2), on which the fire extinguisher 72 is placed horizontally, are pulled outwards from the upper drawer opening 34(34-1) and the lower drawer opening 34(34-2). By holding the fixing lever 7212 (see Figure 10) and the handle 74 of the fire extinguisher 72 with both hands and pulling toward the user (+Z direction) while lifting, either the fire extinguisher 72 on the upper drawer body 32(32-1) side or the fire extinguisher 72 on the lower drawer body 32(32-2) side can be easily and quickly removed.

[0131] [h. Simplification of the fire extinguisher drawer structure with a side fire extinguisher door that is integrated into the top and bottom.] Next, a simplified embodiment of the fire extinguisher drawer structure, which has an integrated upper and lower side fire extinguisher door, will be described in more detail. In this description, refer to Figure 19, which shows the drawer body side of the fire extinguisher drawer structure equipped only with the lower drawer mechanism, and Figure 20, which shows the housing side of the fire extinguisher drawer structure equipped only with the lower drawer mechanism.

[0132] The fire extinguisher pull-out structure of this embodiment is simplified by omitting the upper pull-out mechanism and using only the lower pull-out mechanism.

[0133] As shown in Figure 19, the drawer body side of the fire extinguisher pull-out structure has an upper drawer body 32 (32-1) and a lower drawer body 32 (32-2) installed in two stages inside the side fire extinguisher door 16. The upper drawer body 32 (32-1) consists only of a base 38 (38-1) and does not have the main body guide rails or rollers that constitute the pull-out mechanism, while the lower drawer body 32 (32-2) is equipped with the lower main body guide rail 36 (36-2) and rollers 40 that constitute the lower pull-out mechanism. The base 38 (38-1) is reinforced by a beam member 3813.

[0134] Corresponding to the drawer body side of such a fire extinguisher pull-out structure, on the housing side, as shown in Figure 20, the second housing 11b has a virtual upper fire extinguisher storage section 5010 and a lower fire extinguisher storage section 5020 that are divided vertically into upper and lower sections. The upper fire extinguisher storage section 5010 is not provided with housing guide rails, etc., which constitute the draw-out mechanism on the housing side, while only the lower fire extinguisher storage section 5020 is provided with housing guide rails 42 (42-2), rollers 44 and stoppers 46 that constitute the lower draw-out mechanism.

[0135] Even in the simplified fire extinguisher pull-out structure of this embodiment, when a road user wants to use a fire extinguisher, the lock is released by pulling the door handle 1611 of the side fire extinguisher door 16 towards the user (-X direction). The upper pull-out body 32(32-1) and lower pull-out body 32(32-2), on which the fire extinguisher 72 is placed horizontally, are pulled outwards from the upper pull-out opening 34(34-1) and lower pull-out opening 34(34-2) by the lower pull-out mechanism, which is equipped with a lower body guide rail 36(36-2) and a lower housing guide rail 42(42-2). The fire extinguisher 72 can then be easily and quickly removed by holding the fixing lever 7212 (see Figure 10) and handle 74 of the fire extinguisher 72 with both hands and pulling it towards the user (+Z direction) while lifting it up.

[0136] [i. Embodiment of a fire extinguisher box] The structure of a fire extinguisher box equipped with a fire extinguisher drawer structure that stores the fire extinguisher horizontally will be described in more detail. In this description, refer to Figure 21, which shows an embodiment of a fire extinguisher box equipped with a fire extinguisher drawer structure, and Figure 22, which shows the operation of drawing out the fire extinguisher in the fire extinguisher box of Figure 21. Figure 22(A) shows the state in which the fire extinguisher has been drawn out by operating the upper side drawer door, and Figure 22(B) shows the state in which the fire extinguisher has been drawn out by operating the lower side fire extinguisher door.

[0137] As shown in Figure 21, the fire extinguisher box 100 of this embodiment corresponds to the structure in which the second housing 11b of the fire hydrant device 10 shown in Figures 1 to 20 is separated and the right side is closed. Since the housing 1100 of the fire extinguisher box 100 is provided with a fire extinguisher pull-out structure similar to that of the fire hydrant device 10, the same reference numerals are used and their explanation is omitted.

[0138] Under normal circumstances, as shown in Figure 21, the upper side fire extinguisher door 16(16-1) and the lower side fire extinguisher door 16(16-2) of the fire extinguisher box 100 are locked in a position that closes the drawer opening on the side of the housing, so that the two fire extinguishers are stored horizontally in the fire extinguisher storage section inside the second housing 11b, separated into upper and lower levels.

[0139] When a road user wants to use the fire extinguisher, they pull the upper door handle 1611 of the upper side fire extinguisher door 16 (16-1) towards them (in the -X direction) according to the number "1" on the operation sequence display 1615, which releases the lock, and as shown in Figure 22(A), the upper drawer body 32 (32-1) on which the fire extinguisher 72 is placed horizontally is pulled outwards from the upper drawer opening 34 (34-1).

[0140] At this time, as shown in Figure 8(A), the contact piece 1618 formed at the lower end of the upper side fire extinguisher door 16(16-1) is in contact with the upper inner surface of the lower side fire extinguisher door 16(16-2). As a result, when the upper side fire extinguisher door 16(16-1) is pulled out, the lower side fire extinguisher door 16(16-2) is also pulled out from the lower pull-out opening 34(34-2), making the two horizontally placed fire extinguishers 72 available for removal.

[0141] For road users to retrieve the fire extinguisher 72, for example, they can easily and quickly remove it by holding the fixing lever 7212 (see Figure 10) and handle 74 of the fire extinguisher 72, which is placed horizontally in the upper drawer body 32 (32-1), with both hands and lifting it towards them.

[0142] Next, when a road user wants to take out the fire extinguisher 72 from the lower drawer body 32 (32-2), the upper drawer body 32 (32-1) gets in the way. For example, the upper side fire extinguisher door 16 (16-1) is pushed in to close it, and the fire extinguisher 72, which is placed horizontally in the lower drawer body 32 (32-2), can be easily and quickly removed by holding the fixing lever 7212 (see Figure 10) and handle 74 of the fire extinguisher 72 with both hands and lifting it towards the user.

[0143] Furthermore, since the fire extinguisher 72 can be pulled out from the outside of the side of the fire hydrant device 10's casing, the monitoring staff passage 35 in the front direction of the casing, through which evacuees pass, is not restricted, and the fire extinguisher 72 can be pulled out and removed without obstructing passage in the monitoring staff passage 35.

[0144] Figure 22(B) shows the case where the upper side fire extinguisher door 16(16-1) is closed and a road user operates the lower side fire extinguisher door 16(16-2). By pulling the lower door handle 1612 towards the user (-X direction), the lock on the lower end of the upper side fire extinguisher door 16(16-2) is released, and the lower drawer body 32(32-2), on which the fire extinguisher 72 is placed horizontally, is pulled outwards independently from the lower drawer opening 34(34-2).

[0145] In this case, since the upper side fire extinguisher door 16 (16-1) is in the closed position, the fire extinguisher 72, which is placed horizontally in the lower drawer body 32 (32-2), can be easily and quickly removed by holding the fixing lever 7212 (see Figure 10) and handle 74 of the fire extinguisher 72 with both hands and lifting it towards the user, without being obstructed by the upper drawer body 32 (32-1).

[0146] [j. Modified versions of the present invention] Modifications of the fire hydrant device according to the present invention will now be described. In addition to the embodiments described above, the fire hydrant device of the present invention includes the following modifications. The same applies to the fire extinguisher box.

[0147] (Wall-mounted fire hydrant system) The above embodiment takes as an example a fire hydrant device with a stationary structure in which the housing is attached and fixed to the upper part of a frame installed on the road surface of the guardian's walkway, close to or in contact with the tunnel wall. However, it is not limited to this, and in the case of a wall-mounted fire hydrant device with a housing attached and fixed to the front part on the road side of a frame installed on the tunnel wall above the road surface of the guardian's walkway, a side door is provided on the side of the housing, and by opening the side door, it is possible to work on the inside of the housing from the outside on the side.

[0148] (When the tunnel wall has a cross-section other than circular) Although the tunnel cross-sectional shape in the above embodiment is circular, if the tunnel cross-section is not circular, for example, a three-centered circle, the present invention can be applied by setting the horizontal line at the position with the widest horizontal width of the tunnel cross-sectional shape as the tunnel centerline SL1 in the above description.

[0149] (Structure of a fire hydrant device designed for a thinner design) In the fire hydrant device of the above embodiment, the width of the first and second housings is increased to compensate for the reduction in internal volume due to the thinning of the fire hydrant device. However, the height of the first and second housings may also be increased to compensate for the reduction in internal volume due to the thinning.

[0150] (Downward-facing drawer mechanism) The drawer mechanism of the above embodiment may be configured to support the drawer body so that it is movable in a predetermined angle that is inclined diagonally downward with respect to the horizontal direction of the drawer. The diagonal downward angle is arbitrary, but for example, by supporting the drawer body so that it is movable in a direction that is inclined diagonally downward at an angle of about 2 to 3 degrees with respect to the horizontal direction, when a road user releases the lock on the side fire extinguisher door with the door handle, it becomes possible to pull out the fire extinguisher with little force and expose it in the retrieval position. In addition, the weight of the drawer body in which the fire extinguisher is placed vertically exerts a force that moves it in the inclined direction, making it possible to move the fire extinguisher to the retrieval position even when the door handle is released. Here, "horizontal" is not limited to being parallel to the horizontal direction indicated by a spirit level, i.e., perpendicular to the vertical, but also includes being approximately parallel to the tunnel surface, or at least approximately parallel to the surface corresponding to the installation location if there is a changing gradient on the surface, and further, when the enclosure width direction is installed roughly along such parallel lines, it includes being approximately parallel to the lateral direction (left-right direction, width direction) of the enclosure in the installed state, or approximately perpendicular to the vertical direction (up-down direction, height direction) of the enclosure. Also, a "horizontal line" is a line that is approximately parallel to the "horizontal" direction.

[0151] (Drawer mechanism) In the above embodiment, the drawer mechanism of the fire extinguisher drawer structure uses two guide rails, into which the drawer guide rail of the drawer body is slidably fitted to the fixed housing guide rail. However, it may also be a drawer mechanism using three guide rails, with an intermediate guide rail positioned between the housing guide rail and the drawer guide rail.

[0152] (others) Furthermore, the present invention includes appropriate modifications that do not impair its purpose and advantages, and is not limited by the numerical values ​​shown in the above embodiments. [Explanation of Symbols]
