Description

[Technical Field]

[0001] The present invention relates to a fire hydrant device that stores a fire hose, a fire extinguisher, etc. and is installed in a tunnel, and a fire extinguisher box that stores a fire extinguisher and is installed in a tunnel. [Background technology]

[0002] Conventionally, fire hydrant systems have been installed as emergency tunnel equipment in tunnels such as expressways and expressways. A fire hydrant system consists of a casing with a tilt-forward door (fire hydrant door), a fire hose with a nozzle attached to the end, and valves including a fire hydrant valve, housed in a fire hydrant storage compartment. A fire extinguisher storage compartment with a fire extinguisher door houses, for example, two fire extinguishers. Furthermore, fire hydrant systems are generally installed by embedding boxes into the tunnel wall at intervals of, for example, 50 meters along the length of the tunnel.

[0003] However, in tunnels constructed using methods such as shield tunneling, the structure of the tunnel body makes it difficult to cut out a box in the tunnel wall and install a fire hydrant device by embedding it in place, due to the cost and effort involved, so the fire hydrant must be installed in an exposed position in the guard's passage.

[0004] Furthermore, in order to install the fire hydrant device on the tunnel wall surface without removing the box, a wall-mounted structure has been proposed in which the fire hydrant device is attached and fixed to a stand installed on the tunnel wall surface.In this case, the stand is composed of a main support part fixed to the wall surface and a position-maintaining member that maintains the position of the fire hydrant device (Patent Document 2).

[0005] Furthermore, since wall-mounted fire hydrant devices have issues such as the time and labor required to install them on the tunnel wall, it is being considered to use a so-called stationary structure in which the fire hydrant device is attached and fixed in an exposed state to a stand installed on the road surface of the guard passage, which is easier to install.

[0022] (Operation instructions for the side fire extinguisher door) The housing has an operation instruction displayed on the front and / or side of the housing corresponding to the fire extinguisher storage section, which guides the user on how to remove the fire extinguisher by pulling it out.

[0023] (Fire extinguisher box) The present invention provides a fire extinguisher box having a housing installed at a predetermined height above the road surface of a guard passage provided along the wall surface of a tunnel having a road, in proximity to or in contact with the tunnel wall surface, The fire extinguisher is characterized by having a fire extinguisher drawer structure that allows the fire extinguisher, which is placed horizontally in the fire extinguisher storage section inside the housing, to be taken out and put in from the side of the housing.

[0024] The details of the fire extinguisher drawer structure in the fire extinguisher box are the same as those in the case of the fire hydrant device described above, so their explanation will be omitted. [Effects of the Invention]

[0025] (Effect of fire hydrant devices) According to the present invention, a fire hydrant device has a housing installed close to or abutting the tunnel wall at a predetermined height above the road surface of a monitor's passage provided along the wall of a tunnel having a road, and is provided with a fire extinguisher pull-out structure that allows a fire extinguisher placed horizontally in a fire extinguisher storage section within the housing to be taken in and out from the side of the housing.Therefore, when a road user uses a fire extinguisher to perform firefighting activities, the fire extinguisher can be pulled out by pulling it out toward the side of the housing of the fire hydrant device, and the fire extinguisher can be taken out without obstructing the passage of evacuees through the monitor's passage in front of the housing.

[0026] (Effect of the fire extinguisher drawer structure separated into upper and lower fire extinguisher doors) The fire extinguisher drawer structure allows two fire extinguishers placed horizontally in the fire extinguisher storage section to be taken out and put in from the side of the housing, and includes a drawer 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 each of the upper and lower drawer openings that divide the drawer opening into two sections, one above the other, an upper drawer body located on the bottom side of the upper drawer opening so as to be freely inserted and removed from the upper fire extinguisher storage section, and on which one of the fire extinguishers is placed so as to be freely removed in a horizontally placed state, a lower drawer body located on the bottom side of the lower drawer opening so as to be freely inserted and removed from the lower fire extinguisher storage section, and on which the other fire extinguisher is placed so as to be freely removed in a horizontally placed state, and an upper drawer body fixed to the drawer side end of the upper drawer body and opening and closing the upper drawer opening as the upper drawer body is inserted and removed. The fire extinguisher unit is equipped with a fire extinguisher door on the upper side of the drawer body, a lower side fire extinguisher door that is fixed to the drawer side end of the lower drawer body and opens and closes the lower drawer opening as the lower drawer body is pulled in and out, an upper drawer mechanism that supports the upper drawer body so that it can move freely in the drawer direction relative to the upper fire extinguisher storage part, and a lower drawer mechanism that supports the lower drawer body so that it can move freely in the drawer direction relative to the lower fire extinguisher storage part.Therefore, when a road user pulls the upper side fire extinguisher door or the lower side fire extinguisher door towards them (towards the side of the housing), the upper drawer body or the lower drawer body is pulled out to an exposed position towards the side of the housing, for example, in the same way as opening a desk drawer, and the fire extinguishers pulled out in the horizontal position can be taken out.

[0027] (Effect of the interlocking structure of the upper and lower side fire extinguisher doors) The fire extinguisher drawer structure also includes a drawer 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, the drawer interlocking mechanism is designed so that the outer lower edge of the upper side fire extinguisher door is positioned inside the upper edge of the lower side fire extinguisher door, and as the upper side fire extinguisher door is pulled out, the outer lower edge abuts against the inner upper edge, pulling out the lower side fire extinguisher door. 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 drawer bodies are pulled out simultaneously, allowing for the removal of two fire extinguishers placed horizontally in each. Note that after the upper fire extinguisher is removed, road users can push the upper side fire extinguisher door back into the housing, making it easier to remove the lower fire extinguisher. Furthermore, the lower side fire extinguisher door can be pulled out independently without being linked to the upper side fire extinguisher door, allowing for the removal of one fire extinguisher placed horizontally in the lower drawer body.

[0028] (Door handle effect) In addition, the upper side fire extinguisher door is equipped with an upper door handle that releases the lock with the upper drawer opening in response to the drawer operation, and the lower side fire extinguisher door is equipped with a lower door handle that releases the lock with the upper side fire extinguisher door in response to the drawer 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, and when a road user wants to use a fire extinguisher, they can place their hand on the upper door handle or the lower door handle and perform the drawer operation, which releases the lock, allowing them to easily pull out the upper drawer body or the lower drawer body with the fire extinguisher placed horizontally to a position exposed to the outside toward the side of the housing.

[0029] (Effect of displaying the equipment name on the side fire extinguisher door) In addition, the word "fire extinguisher" is displayed on the sides of the housing, including the upper side fire extinguisher door and the lower side fire extinguisher door, making it easy for road users to understand that the door for removing the fire extinguisher from the fire hydrant device is located on the side of the housing.

[0030] (Effect of displaying the operation order on the fire extinguisher door) In addition, the upper and lower side fire extinguisher doors are marked with letters, figures or symbols indicating the order of operation. For example, by displaying "1" on the upper side fire extinguisher door and "2" on the lower side fire extinguisher door, road users will follow the numbers indicating the order and pull out the upper side fire extinguisher door and then the lower side fire extinguisher door, making it possible to pull out the fire extinguishers without hesitation even if there are two side fire extinguisher doors.

[0031] (Effect of the fire extinguisher drawer structure with the upper and lower side fire extinguisher doors integrated together) In addition, the fire extinguisher drawer structure is made up of an upper side fire extinguisher door and a lower side fire extinguisher The side fire extinguisher door is an integrated door, and the side fire extinguisher door is divided into two sections on the inside, upper and lower, with an upper drawer body and a lower drawer body. When the side fire extinguisher door is pulled out, the upper and lower drawer bodies are pulled out as a unit, making it possible to remove either or both of the two fire extinguishers placed horizontally on each side.

[0032] (Effect of the drawer mechanism of the fire extinguisher drawer structure with the upper and lower side fire extinguisher doors integrated together) Furthermore, the fire extinguisher drawer structure can simplify the drawer mechanism by omitting the upper drawer mechanism and providing only the lower drawer mechanism.

[0033] Even in this case, the side fire extinguisher door is equipped with a door handle that releases the lock with the drawer opening in response to the drawer operation, so that under normal circumstances the side fire extinguisher door is securely locked by the door handle, and when a road user uses the fire extinguisher, they place their hand on the door handle and perform the drawer operation, which releases the lock, allowing the upper and lower drawer bodies on which the fire extinguisher is placed horizontally to be easily pulled out to a position exposed to the outside on the side of the housing.

[0034] In addition, the side fire extinguisher door is marked with the word "fire extinguisher," making it easy for road users to understand that the door for removing the fire extinguisher from the fire hydrant device is located on the side of the housing.

[0035] (The fire extinguisher name and viewing window on the front of the case) In addition, the housing has the word "fire extinguisher" written horizontally or vertically on the front side corresponding to the fire extinguisher storage section, so that road users can easily see which side of the fire hydrant device the fire extinguisher is stored on.In addition, the housing is provided with a sight window that allows the storage status of the fire extinguisher to be seen, so that it can be easily confirmed from the outside that the fire extinguisher is stored correctly during inspection, etc.

[0036] (Effect of explaining how to operate the side fire extinguisher door) Furthermore, the housing has an operation instruction displayed on the front and / or side corresponding to the fire extinguisher storage section, which guides users on how to remove the fire extinguisher by pulling it out, so that road users who want to remove the fire extinguisher from the fire hydrant device can see the operation instruction on the front of the housing and know that the fire extinguisher door is located on the side of the housing and that the fire extinguisher can be removed by pulling out the side door, and can reliably pull out and remove the fire extinguisher using the side door. In particular, it is commonly known that the fire extinguisher door of a conventional fire hydrant device is provided on the front of the housing so that it can be freely opened sideways, and the side door on the side of the housing according to the present invention has a unique structure that is not found in conventional common sense, so that road users can remove the fire extinguisher by pulling out the side door provided on the side of the housing without any confusion, thanks to the operation instruction on the front of the housing.

[0037] (Fire extinguisher box effect) The fire extinguisher box of the present invention also provides the same effects as the fire hydrant device described above, so a description thereof will be omitted. [Brief explanation of the drawings]

[0039] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a fire hydrant device and a fire extinguisher box according to the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the following preferred embodiments.

[0040] [Basic concept of the embodiment] First, a basic concept of the embodiment will be described. The embodiment generally relates to a fire hydrant device in which a fire hydrant device and a fire extinguisher are arranged in a housing.

[0041] Here, a "fire hydrant device" is a type of emergency equipment installed in areas subject to fire extinguishing, such as tunnels on expressways and motorways, and is a housing installed in the area subject to fire extinguishing, in which fire hydrant equipment such as fire hoses, electrical equipment such as red indicator lights and transmitters on electrical doors, and fire extinguishers are placed or stored, and the concept includes fire hydrant facilities in which fire hydrant devices are installed.

[0042] The fire hydrant device is installed in an exposed state at a predetermined height above the road surface of a guard passageway that is provided along the interior wall of a tunnel that has a road. Here, the "predetermined height" refers to a height that allows the fire hydrant device to be installed in a position close to or in contact with the tunnel wall, and can be installed at the predetermined height by, for example, attaching and fixing a housing to the top of a platform installed on the road surface of the guard passageway, or by attaching and fixing a housing to the front part of a platform installed on the tunnel wall above the road surface of the guard passageway, which faces the road.

[0043] Furthermore, the term "frame" refers to a structure that supports an object using pillars, beams, etc., and although specific examples are not shown, it includes concepts such as a support base, foundation, base, seat, and base.

[0044] The fire hydrant device of this embodiment is characterized by the provision of a fire extinguisher drawer structure that allows a fire extinguisher placed horizontally in a fire extinguisher storage section within the housing to be taken in and out from the side of the housing, and when a road user uses a fire extinguisher to perform firefighting activities, the fire extinguisher can be pulled out toward the side of the housing of the fire hydrant device without obstructing the passage of the guard passage. Here, "placing the fire extinguisher horizontally" means placing the fire extinguisher in a lying position, which makes it possible to reduce the vertical storage space for the fire extinguisher within the housing.

[0045] The "fire extinguisher drawer structure" stores and draws out two fire extinguishers individually, one above the other, corresponding to the two separate side fire extinguisher doors in this embodiment. Its structure and shape are arbitrary, but for example, it is composed of an upper fire extinguisher drawer structure and a lower fire extinguisher drawer structure. The upper drawer structure is composed of an upper fire extinguisher storage section, an upper drawer body, an upper side fire extinguisher door, and an upper drawer mechanism. The lower fire extinguisher storage structure is composed of a lower fire extinguisher storage section, a lower drawer body, a lower side fire extinguisher door, and a lower drawer mechanism.

[0046] Taking the upper fire extinguisher drawer structure as an example, the "upper fire extinguisher storage section" refers to a storage section formed above the fire extinguisher storage section in the housing, corresponding to the upper drawer opening divided into two sections, upper and lower. The "upper drawer main body" refers to a section located at the bottom of the upper drawer opening, allowing the fire extinguisher to be freely inserted and removed from the upper fire extinguisher storage section. The "upper side fire extinguisher door" refers to a fire extinguisher door fixed to the drawer-side end of the upper drawer main body, which opens and closes relative to the upper drawer opening as the upper drawer main body is inserted and removed. The "fire extinguisher door" in this embodiment does not refer to a section that opens and closes, but rather refers to a structure fixed to the drawer-side end of the drawer main body, and includes concepts such as a fire extinguisher drawer panel, side panel, and fire extinguisher storage section cover.

[0047] The "upper drawer mechanism" is a mechanism that supports the upper drawer body so that it can move freely in the drawer direction relative to the upper fire extinguisher storage section, and although its structure and function are arbitrary, it can be used, for example, as a drawer mechanism for an office desk or document locker, in which a guide rail fixed to the housing side is slidably fitted into a guide rail fixed to the drawer body side via a guide roller. The same applies to the lower fire extinguisher drawer structure, if you read "upper" as "lower".

[0048] The upper side fire extinguisher door and the lower side fire extinguisher door can be pulled out individually, allowing road users to pull out the fire extinguishers placed horizontally in each drawer body and remove them one by one.In this embodiment, a drawer linkage structure is provided so that 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, making it possible to remove two fire extinguishers by pulling out the upper side fire extinguisher door.

[0049] In addition, the upper and lower side fire extinguisher doors are marked with letters, figures or symbols indicating the order of operation, for example, numbers such as "1" on the upper side fire extinguisher door and "2" on the lower side fire extinguisher door, and these numbers guide road users, for example, when to remove the fire extinguisher by pulling out the upper side fire extinguisher door.

[0050] In addition, an upper door handle is provided on the upper side fire extinguisher door, and a lower door handle is provided on the lower side fire extinguisher door. Here, the "upper door handle" is what releases the lock with the upper drawer opening in response to the drawer operation, and normally the upper side fire extinguisher door is locked by the lock with the upper door handle, and when a road user pulls out the upper door handle, the lock is released and the upper drawer body can be pulled out to a position exposed to the outside in the direction of the side of the housing, allowing the fire extinguisher to be removed.

[0051] In addition, the "lower door handle" releases the lock with the upper side fire extinguisher door in response to the pull-out operation; under normal circumstances, the lower side fire extinguisher door is locked by the lower door handle engaging with the upper side fire extinguisher door; when a road user pulls out the lower door handle, the lock is released, and the lower drawer body can be pulled out to a position exposed to the outside toward the side of the housing, allowing the fire extinguisher to be removed.

[0052] The side fire extinguisher door may also be a single, integrated door, rather than being divided into two, upper and lower, pieces. In this case, two fire extinguishers can be removed by pulling out one side fire extinguisher door. In this case, the pull-out mechanism may only have a lower pull-out function, without an upper pull-out mechanism.

[0053] In addition, the word "fire extinguisher" is written vertically on the side of the housing including the upper side fire extinguisher door and the lower side fire extinguisher door, and this word indicates to road users that the fire extinguisher door is installed 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 section, and this word also makes it easy to understand which side of the fire hydrant device the fire extinguisher is stored on.

[0054] In addition, a "sight window" is provided on the front of the housing corresponding to the fire extinguisher storage section, which makes it easy to check from the outside that the fire extinguisher is stored correctly during inspection, etc.

[0055] In addition, "fire extinguisher operation instructions" are displayed on the front and / or side of the housing corresponding to the fire extinguisher storage section. Here, the "fire extinguisher operation instructions" are a display that guides users on how to remove the fire extinguisher by pulling out the side fire extinguisher door. Road users who wish to remove a fire extinguisher from the fire hydrant device can see the "fire extinguisher operation instructions" on the front of the housing and know 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, making it possible for them to easily remove the fire extinguisher.

[0056] In particular, it is commonly known that the fire extinguisher door of a conventional fire hydrant device is provided on the front of the housing so that it can be freely opened sideways. Even so, the "fire extinguisher operation instructions" on the front of the housing allow road users to easily remove the fire extinguisher by pulling out the side fire extinguisher door provided on the side of the housing.

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

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

[0059] Specific embodiments will be described below. In the specific embodiments shown below, a case will be described in which "a fire hydrant device is attached and fixed to a stand installed above the guard passage in the tunnel," a "fire extinguisher drawer storage structure" is provided in the fire extinguisher storage section of the housing, and the fire extinguisher storage section is divided into two levels, upper and lower, and provided with an "upper fire extinguisher drawer structure" and a "lower fire extinguisher drawer structure."

[0061] [a. Overview of the fire hydrant equipment] The outline of the fire hydrant device with a fire extinguisher drawer structure will be explained in more detail below. In this explanation, reference will be made to Figure 1, which shows the installation state of the fire hydrant device with a fire extinguisher drawer structure in a tunnel in a longitudinal cross section (cross section in the longitudinal direction of the tunnel), and Figure 2, which shows the installation state of the fire hydrant device in Figure 1 in a cross section of the tunnel.

[0062] 1 and 2, the X, Y, and Z directions are directions that are orthogonal to each other. Specifically, when looking at the front face of the fire hydrant device 10 from the front, the X direction is the left-right direction, the Y direction is the up-down direction, and the Z direction is the front-to-back direction. In addition, the +X side in the X direction is the right side, the -X side is the left side, the +Y side in the Y direction is the upper side, the -Y side is the lower side, and the +Z side in the Z direction is the front side, and the -Z side is the rear side. In this respect, the X, Y, and Z directions are the same in Figures 3 to 22, which illustrate embodiments of the present invention.

[0063] As shown in Fig. 1, the housing of the fire hydrant device 10 of 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 halves, with a tilt-forward door 12 that functions as a fire hydrant door and opens downward on hinges 12a being located at the lower side of the door opening, and a maintenance door 14 that opens upward on hinges 14a being located at the upper side of the door opening. A fire hydrant device storage compartment inside the first housing 11a stores predetermined fire hydrant devices, including fire hoses and valves such as a fire hydrant valve.

[0064] A decorative frame 13b is attached to the front of the second housing 11b. A door opening is provided above the decorative frame 13b, and an electrical door 18 that opens downward via hinges 18a is disposed in the door opening. The electrical door 18 is provided with electrical equipment such as a red indicator light 22, a transmitter 24, and an answer lamp 25, and is also provided with a telephone jack on the inside.

[0065] The red indicator light 22 is always lit, allowing the installation location of the fire hydrant device 10 to be confirmed from a distance. When a fire breaks out and the transmitter 24 is pressed to turn on the push button switch, a transmission signal is sent, which is received by a disaster prevention receiving panel installed in an electrical room or the like and issues a fire alarm. 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 housing 11b is a fire extinguisher storage section, and on the left side surface of the second housing 11b near the fire extinguisher storage section, an upper side fire extinguisher door 16(16-1) and a lower side fire extinguisher door 16(16-2) are provided in two upper and lower stages, as shown in FIG. 2. The upper side fire extinguisher door 16(16-1) is provided with an upper door handle 1611 and an operation order indicator 1615 consisting of the number "1" in a circle (Arabic numeral). The lower side fire extinguisher door 16(16-2) is provided with a lower door handle 1612 and an operation order indicator 1616 consisting of the number "2" in a circle. Note that the operation order indicators 1615, 1616 may be, in addition to Arabic numerals, English letters (Roman letters) "A" and "B" or Roman numerals "I" and "II," etc.

[0067] When a road user places their hand on the upper door handle 1611 and pulls the upper side door 16 (16-1) forward (toward the side), the latch is released and the door can be pulled out to an exposed state where a fire extinguisher stored in the upper part of the fire extinguisher storage section can be removed. When a road user places their hand on the lower door handle 1612 and pulls the lower side door 16 (16-2) forward (toward the side), the latch is released and the door can be pulled out to an exposed state where another fire extinguisher stored in the lower part of the fire extinguisher storage section can be removed. In this embodiment, a pull-out interlocking structure is provided whereby when the upper side door 16 (16-1) is pulled out, the lower side door 16 (16-2) is pulled out in conjunction with this.

[0068] In addition, on the side of the housing above the upper side fire extinguisher door 16 (16-1), there is provided an equipment name display 1613 with the word "fire extinguisher" written vertically, and an operation instruction 1614 that displays, using graphics or the like, instructions on how to pull out the fire extinguisher so that it can be removed.

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

[0070] [b. Installation of fire hydrant equipment] The installation of fire hydrant equipment inside tunnels will be explained in more detail below. As shown in Figures 1 and 2, a road 15 is constructed in the longitudinal direction (left and right direction) of the tunnel below the cylindrical (circular cross section) tunnel body constructed using the shield tunneling method, and a guard passage 35 is constructed at a predetermined height above the road 15 below the tunnel wall 17 along the rear side of the road 15.

[0071] Since it is difficult to cut out a box from the tunnel wall 17 constructed by the shield construction method to install the fire hydrant device 10, the mount 30 is installed close to the tunnel wall 17 on the road surface of the monitor's passage 35, and the connected first housing 11a and second housing 11b are attached and fixed to the mount 30, thereby installing the fire hydrant device 10. Here, the height H1 of the mount 30 is set so that the height from the road surface of the monitor's passage 35 to the transmitter 24 installed on the fire hydrant device 10 is within the legally specified range of 800 mm to 1500 mm.

[0072] 2, the side shape of the mount 30 of this embodiment is an inverted trapezoid with the top side longer than the bottom side, and the rear side is a surface that slopes diagonally downward to fit the curved shape of the tunnel wall surface 17. The first housing 11a and second housing 11b of the fire hydrant device 10, which are connected to each other, are attached and fixed to the upper end surface of the mount 30. A water supply pipe 48 that rises from inside a duct below the road surface of the monitor passage 35 through the mount 30 is connected to the fire hydrant device 10.

[0073] [c. Installation height and thinness of fire hydrant equipment] The installation height and thinness of the fire hydrant device will be explained in more detail below, with reference to Figure 3, which is an explanatory diagram showing the installation state of the fire hydrant device on the cross section of the tunnel.

[0074] In this embodiment, in order to reduce the restriction on the passage width caused by the protrusion (projection) of the fire hydrant device 10, which is installed on the road surface of the monitor passage 35 by the stand 30, from the tunnel wall surface 17, the installation height of the fire hydrant device 10 is optimized, and at the same time, 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 mounting base 30, we will explain in more detail how to optimize the height H1 of the mounting base 30. The tunnel wall 17 on which the fire hydrant device 10 is installed has a circular cross section, and in Figure 3(A), the height H1 of the mounting base 30 is set so that the horizontal housing center line SL2 passing through the center of the height direction of the fire hydrant device 10 installed on the monitor passage 35 is as close as possible to the horizontal tunnel center line SL1 from the tunnel center (center of the circular cross section) P.

[0076] In this case, the closer the housing center line SL2 is to the tunnel center line SL1, the more the degree to which the fire hydrant device 10 protrudes from the tunnel wall surface 17 can be reduced.

[0077] 3(B) shows a case where the height H1 of the mount 30 is set so that the housing center line SL2 coincides with the tunnel center line SL1. In this case, the degree to which the fire hydrant device 10 protrudes from the tunnel wall surface 17 can be minimized. However, the height H1 of the mount 30 is adjusted within the possible range, taking into account the ease of removing the fire extinguisher, etc.

[0078] Next, a more detailed explanation will be given of how the fire hydrant device 10 can be made thinner. Of the devices housed in the fire hydrant device 10, the fire extinguisher housed in the second housing 11b is the device with the largest size in the front-to-rear direction, and the fire hydrant device 10 can be made thinner if the width (thickness in the front-to-rear direction) of the fire hydrant device is the minimum value that allows the fire extinguisher to be housed in the second housing 11b, so the width of the fire hydrant device 10 is set to a predetermined width that corresponds to the outer diameter of the fire extinguisher housed in the second housing 11b.

[0079] The outer diameter of the fire extinguisher is about 150 to 160 mm, and 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 is, for example, within a range of about 180 to 200 mm, and the width of the fire hydrant device 10 is set to a predetermined width within that range. In contrast, the width of a conventional fire hydrant device 10 that is installed by cutting a box out of the wall surface of a tunnel body and embedding it in place is about 300 mm, so the width of the fire hydrant device 10 of this embodiment can be made two-thirds or less of the conventional one, allowing the fire hydrant device 10 to be made thinner.

[0080] [d. Configuration compatible with thinner fire hydrant devices] If the fire hydrant device 10 is thinned to a predetermined width in the range of about 180 to 200 mm corresponding to the outer diameter of the fire extinguisher, it becomes difficult to store a fire hose of a predetermined length, for example, a 30 m shape-retaining hose, in an inwardly coiled state in the first housing 11a, 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 fire hydrant devices in an inwardly coiled state.

[0081] [e. Structure of a fire hydrant device with a side fire extinguisher door] The structure of a fire hydrant device equipped with a side fire extinguisher door will be described in more detail. In this description, reference will be made to Fig. 4, which shows the internal structure of the fire hydrant device from the front with the tilting door open, Fig. 5, which shows the internal structure of the fire hydrant device in plan view, Fig. 6, which shows the internal structure of the fire hydrant device from the right side, and Fig. 7, which shows the side (left side) of the fire extinguisher storage side of the fire hydrant device. Of these, Fig. 5 is a cross section indicated by section line aa in Fig. 4, and Fig. 6 is a cross section indicated by section line bb in Fig. 4. Note that the tilting door 12 in Fig. 6 shows the side of the door in Fig. 4.

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

[0083] The hydrant valve 54 is opened and closed by a hydrant valve opening / closing lever 58, and when the hydrant valve opening / closing lever 58 is opened or closed, the hydrant valve 54 is remotely opened or closed by a known wire link mechanism. When the hydrant valve opening / closing lever 58 is opened or closed, a pump start interlock switch provided on the operation box turns on or off. In addition, a pump start switch 64 for use by the fire brigade is provided on the upper right of the hydrant 52.

[0084] A hose storage frame 62 is provided in the hose storage section 50b, and the fire hose 60, which is pulled in from below, is stored in a state of being wound inward clockwise or counterclockwise. Here, the hose storage frame 62 has a wider width to accommodate the wider width of the first housing 11a that accompanies the slimming of the fire hydrant device 10, and it is possible to store the fire hose 60 of the same predetermined length as in conventional fire hydrant devices with fewer windings than in conventional fire hydrant devices. In addition, a nozzle 68 is attached to the tip of the fire hose 60 pulled out through the hose guide 66, and the nozzle 68 is detachably held in a nozzle holder 70.

[0085] As shown in FIG. 6, a cable rack 49 is provided above the hose storage section 50b to allow cables pulled in from outside the first housing 11a, for example, cables that are raised through the stand 30, to be routed to the second housing 11b, and 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 housing) The structure of the electrical equipment side of second housing 11b will be described in more detail below. As shown in Figures 4 and 5, the interior of second housing 11b is a fire extinguisher storage section 50c, and an electrical equipment door 18 that opens downward on hinges 18a is located in the door opening on the upper front side of second housing 11b. On electrical equipment door 18, from right to left, a red indicator light 22, a transmitter 24, a telephone jack 28, and an answer lamp 25 are located, and the telephone jack 28 is located inside electrical equipment door 18.

[0087] Here, of the electrical equipment, the red indicator light 22 has the largest size in the front-to-rear direction in the fire extinguisher storage section 50c inside the second housing 11b, and its size is approximately 120 mm.Therefore, even if the fire hydrant device 10 is made thin to a predetermined width in the range of approximately 180 to 200 mm, each electrical equipment can be arranged while ensuring space for the cables pulled in from the first housing 11a side.

[0088] Terminal boxes 26a and 26b are arranged in the left-right direction on the rear surface of the interior of second housing 11b opposite electrical door 18. Terminal boxes 26a and 26b are composed of a box body and a lid member, and when placed in second housing 11b, their dimensions (length (up and down) × width (left and right) × depth (front and back)) are approximately 140 mm × 220 mm × 80 mm.

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

[0090] (e3. Fire extinguisher storage area) 4 and 5, in the fire extinguisher storage section 50c inside the second housing 11b, two fire extinguishers 72 with an outer diameter of about 150 to 160 mm are stored horizontally in two separate upper and lower stages using a fire extinguisher drawer structure. Also, as mentioned above, in order to make the fire hydrant device 10 thinner, the width of the fire hydrant device 10 is set to a predetermined width in the range of 180 to 200 mm corresponding to the outer diameter of the fire extinguisher 72, and gaps of about 15 to 25 mm are secured in front and behind the stored fire extinguisher 72, allowing the fire extinguisher 72 to be stored without coming into contact with the second housing 11b.

[0091] 7, on the left side surface of the second housing 11b near the fire extinguisher storage section 50c, an upper side fire extinguisher door 16 (16-1) is disposed in the upper drawer opening 34 (34-1) so as to be freely drawn out toward the front, and a lower side fire extinguisher door 16 (16-2) is disposed in the lower drawer opening 34 (34-2) so as to be freely drawn out toward the front, as in FIG. 2, and 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, an equipment name 1613 with "fire extinguisher" written horizontally and an operation instruction 1614 are provided on the side surface of the housing above the door.

[0092] As shown in Fig. 4, a fire extinguisher 72 is placed horizontally and removably in each of the upper drawer body 32 (32-1) of the upper fire extinguisher drawer structure 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 drawer structure fixed to the inside of the lower side fire extinguisher door 16 (16-2). Therefore, 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 imaginary lines in Fig. 5, making it possible to remove the fire extinguisher 72.

[0093] [f. Fire extinguisher drawer structure] The fire extinguisher draw-out structure will be described in more detail below with reference to Fig. 8 showing the drawer body of the fire extinguisher draw-out structure removed, Fig. 9 showing the detailed structure of the upper drawer body, Fig. 10 showing the fire extinguisher used in this embodiment, Fig. 11 showing the housing side of the fire extinguisher draw-out structure, Fig. 12 showing the operation of the lower draw-out mechanism of the fire extinguisher draw-out structure removed, Fig. 13 showing the fire hydrant device in a fire extinguisher storage state with the side fire extinguisher door closed, Fig. 14 showing the pull-out operation of the lower side draw-out door linked to the pull-out operation of the upper side fire extinguisher door, and Fig. 15 showing the pull-out operation of the lower side fire extinguisher door.

[0094] 8(A) and (B) show the drawer-side structure of the upper and lower fire extinguisher drawer structures, and Fig. 9(A), (B), (C), (D), and (E) show the side, rear, front, and rear views of the fire extinguisher drawer structure, as well as an enlarged cross section of section line dd in Fig. 9(A). Also, Fig. 11(A), (B), (C), and (D) show the front, side cross section, and top cross section of the housing side of the fire extinguisher drawer structure, as well as an enlarged view of part A of the housing guide rail.

[0095] The fire extinguisher drawer structure allows road users to pull out fire extinguishers stored horizontally in two upper and lower levels in the fire extinguisher storage section of the second housing 11b from inside the housing 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 be composed of an upper fire extinguisher drawer structure and a lower fire extinguisher drawer structure, and the upper fire extinguisher drawer structure and the lower fire extinguisher drawer structure may each be composed of a drawer side structure and a housing side structure.

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

[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 move it to the outside of 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 state to the inside of the lower part of the upper side fire extinguisher door 16 (16-1).

[0098] The stand 38 (38-1) is used to place the fire extinguisher in a horizontally placed state, and in order to hold the horizontally placed fire extinguisher 72, a support frame 3810 using a metal round bar or the like stands up from the depth side of the stand 38 (38-1) to the center of the side that is the back side of the fire hydrant device 10, and a front stopper 3811 using an elastic material such as rubber is provided on the plate surface near the door side, and a side stopper is provided on the plate surface near the side that is the fire extinguisher removal side (the front side of the fire hydrant device 10). 3 812 is provided.

[0099] The main body guide rails 36 (36-1) of the upper drawer mechanism are fixed to the outside of the side plates on both sides of the stand 38 (38-1). As shown in Fig. 9(E), which is an enlarged cross section of the section line dd in Fig. 9(A), the main body guide rails 36 (36-1) have a rail protrusion 3610 with a rectangular cross section arranged on the outside of the side plates of the stand 38 (38-1). In addition, a roller 40 is provided at the tip of the rear side (right side) of the main body guide rail 36 (36-1), and a stopper piece 3611 with an inclined surface that is raised on the front side (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 display 1615. The upper door handle 1611 has a latch claw 1617 facing upward on the rear surface of the door, and when the upper door handle 1611 is pulled toward you, the latch claw 1617 retracts, releasing the door lock on the upper drawer opening on the side of the housing and allowing the fire extinguisher to be drawn out.

[0101] Furthermore, an abutment piece 1618 that is bent downward from the inside is formed integrally with the lower end of the upper side fire extinguisher door 16 (16-1), and the abutment piece 1618 is located inside the upper end of the lower side fire extinguisher door 16 (16-2) shown in Figure 8 (B). Therefore, when the upper side fire extinguisher door 16 (16-1) is pulled out, the abutment piece 1618 abuts against the inside of the upper end of the lower side fire extinguisher door 16 (16-2), thereby configuring 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 drawer side of the lower fire extinguisher drawer structure) The structure of the drawer side of the lower fire extinguisher drawer structure will be described in more detail. The drawer side of the lower fire extinguisher drawer structure is a structure for inserting and removing a fire extinguisher into and from the lower fire extinguisher storage section of the housing, and while its shape and structure are arbitrary, 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 move it to the outside of the side of the housing, and one end of the stand 38 (38-2) is fixed in a cantilevered position to the inside lower part of the lower side fire extinguisher door 16 (16-2).

[0104] The stand 38 (38-2) is used to place the fire extinguisher in a horizontally placed state, and in order to hold the horizontally placed fire extinguisher 72, a support frame 3810 using a metal round bar or the like stands up from the depth side of the stand 38 (38-2) to the center of the side that is the back side of the fire hydrant device 10, and a front stopper 3811 using an elastic material such as rubber is provided on the plate surface on the door side, and a side stopper is provided on the plate surface near the side that is the side where the fire extinguisher is taken out (the front side of the fire hydrant device 10). 3 812 is provided.

[0105] The main body guide rails 36 (36-2) of the lower drawer mechanism are fixed to the outside of the side plates on both sides of the stand 38 (38-2). The main body guide rails 36 (36-2) have a rail protrusion 3610 with a rectangular cross section arranged on the outside of the side plates of the stand 38 (38-2). In addition, a roller 40 is provided at the tip of the rear side (right side) of the main body guide rail 36 (36-2), and a stopper piece 3611 with an inclined surface that is raised on the front side (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 rear surface of the door, and when the lower door handle 1612 is pulled toward you, the latch claw 1619 retracts, and the abutment piece 1618 at the lower end of the upper side fire extinguisher door 16 (16-1) shown in Figure 8 (A) against the inside is released, allowing the door to be pulled out.

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

[0108] When a road user removes such a fire extinguisher 72 from a horizontally placed state, the user grasps the fixing lever 7212 to remove the fire extinguisher 72, but to facilitate removal of the horizontally placed fire extinguisher 72, the handle 74 is fastened and fixed near the center of the trunk of the fire extinguisher body 7210 with two bands 76. The fixing structure of the handle 74 to the fire extinguisher body 7210 is arbitrary, and includes fixing by an appropriate method other than the bands 76, such as adhesive. Therefore, by holding both the fixing lever 7212 and the handle 74, the road user can easily remove the fire extinguisher 72 even when it is horizontally placed.

[0109] (f4. Structure of the housing) The structure of the housing side of the fire extinguisher drawer structure will be described in more detail. The housing side structure of the fire extinguisher drawer structure supports the upper drawer body 32 (32-1) and the lower drawer body 32 (32-2) so that they can be freely drawn out within the housing, and although the shape and structure thereof are arbitrary, 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 drawer opening 34 (34-1) and a lower fire extinguisher storage section 5020 having a lower drawer opening 34 (34-2), and 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 main body 32 (32-1) and the lower drawer main body 32 (32-2) shown in Fig. 8. In addition, 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 sideways, as shown in Fig. 11(D), which is an enlarged view of part A in Fig. 11(A), and the roller 40 arranged at the tip side of the corresponding main body guide rail 36 (36-2) shown in Fig. 8 rolls inside the U-shaped frame plate member.

[0111] The upper housing guide rail 42 (42-1) and the lower housing guide rail 42 (42-2) have openings 4210 that widen upward toward the corresponding upper drawer opening 34 (34-1) and lower drawer opening 34 (34-2), so that the rollers 40 at the ends of the main body guide rails 36 (36-1) and 36 (36-2) shown in Fig. 8 can be inserted into the rails from diagonally above. A stopper 46 is fixed above the openings 4210 of the upper housing guide rail 42 (42-1) and the lower housing guide rail 42 (42-2) via a predetermined gap, 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, a stopper piece 3611 abuts against them to prevent them from slipping out.

[0112] Furthermore, rollers 44 are disposed below the openings 4210 of the upper housing guide rail 42 (42-1) and the lower housing guide rail 42 (42-2). The upper sides of the rollers 44 extend beyond the bottom surfaces of the upper housing guide rail 42 (42-1) and the lower housing guide rail 42 (42-2) and enter inside, so that the lower surfaces of the rail protrusions 3610 of the main body guide rails 36 (36-1), 36 (36-2) inserted into the upper housing guide rail 42 (42-1) and the lower housing guide rail 42 (42-2) can move while resting on the rollers 44.

[0113] (f5.Drawer mechanism) The draw-out mechanism in the fire extinguisher draw-out structure will be described in more detail. The draw-out mechanism is divided into an upper draw-out mechanism and a lower draw-out mechanism, and in this description, reference will be made to Figure 12, which shows the operation of the lower draw-out mechanism of the fire extinguisher draw-out structure. Note that Figure 12(A) shows the state in which the draw-out side is removed, Figure 12(B) shows the initial state in which the draw-out side is inserted or the state in which it is fully drawn out, Figure 12(C) shows the state in the middle of being drawn out, and Figure 12(D) shows the state in which the draw-out side is closed. Also, the overlapping portions of the guide rails in Figures 12(B) to (D) are shown in perspective.

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

[0115] When storing the lower drawer main body 32 (32-2) in the lower fire extinguisher storage section 5020 on the housing side, the worker aligns the roller 40 at the tip of the drawer guide rail 36 (36-2) provided on the lower drawer main body 32 (32-2) 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) facing diagonally downward. At this time, the stopper piece 3611 of the drawer guide rail 36 (36-2) is inserted so that it passes above 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 protrusion 3610 of the main body guide rail 36 (36-2), and further, the stopper piece 3611 abuts against the stopper 46 to prevent it from coming out, and this state is the position where the lower drawer main body 32 (32-2) is pulled out furthest from the housing side.

[0117] Next, when the lower side fire extinguisher door 16 (16-2) is pushed in, the rollers 40 and 44 roll, and the lower housing guide rail 4 2 (4 2 The main body guide rail 36 (36-2) moves smoothly relative to the lower drawer main body 32 (32-2) and, as shown in Figure 12 (D), the lower drawer main body 32 (32-2) can be moved to a position where it is completely stored in the lower fire extinguisher storage section 5020.

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

[0119] (f6. Fire extinguisher withdrawal operation) The operation of drawing out the fire extinguisher using the fire extinguisher drawer structure will be explained in more detail below. In this explanation, reference will be made to Figure 13, which shows the fire extinguisher storage state with the side fire extinguisher door closed, Figure 14, which shows the drawing operation of the lower side fire extinguisher door linked to the drawing operation of the upper side fire extinguisher door, and Figure 15, which shows the drawing 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 a 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) toward themselves (in the -X direction) in accordance with the number "1" in the operation sequence display 1615, and as shown in Figure 14, the upper drawer body 32 (32-1) on which the fire extinguisher 72 is placed horizontally is pulled outward from the upper drawer opening 34 (34-1).

[0121] At this time, the abutment piece 1618 formed at the lower end of the upper side fire extinguisher door 16 (16-1) shown in Figure 8 (A) abuts against the inner surface of the upper end of the lower side fire extinguisher door 16 (16-2), so that the lower side fire extinguisher door 16 (16-2) also begins to operate in conjunction with the pulling out operation of the upper side fire extinguisher door 16 (16-1), and when both the upper drawer body 32 (32-1) and the lower drawer body 32 (32-2) are pulled out from the corresponding upper drawer opening 34 (34-1) and lower drawer opening 34 (34-2), the two fire extinguishers 72 placed horizontally can be removed.

[0122] For example, a road user can simply and easily remove the fire extinguisher 72 by holding the fixed 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 toward them.

[0123] Next, when a road user wants to remove the fire extinguisher 72 from the lower drawer body 32 (32-2), since the upper drawer body 32 (32-1) gets in the way, the road user can simply and easily remove the fire extinguisher 72 by, for example, pushing the upper side fire extinguisher door 16 (16-1) closed, and then holding the fixed lever 7212 (see Figure 10) and handle 74 of the fire extinguisher 72 placed horizontally in the lower drawer body 32 (32-2) with both hands and lifting it toward them.

[0124] In addition, since the fire extinguisher 72 can be pulled out to the outside of the side of the housing of the fire hydrant device 10, the guard passage 35 in the front direction of the housing through which evacuees pass is not restricted, and the fire extinguisher 72 can be pulled out and taken out without obstructing passage through the guard passage 35.

[0125] Figure 15 shows a case where a road user pulls out the lower side fire extinguisher door 16 (16-2) while the upper side fire extinguisher door 16 (16-1) is closed. By pulling the lower door handle 1612 forward (in the -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 out alone from the lower drawer opening 34 (34-2) to the outside.

[0126] In this case, since the upper side fire extinguisher door 16 (16-1) is in the closed position, the fire extinguisher 72 placed horizontally in the lower drawer body 32 (32-2) can be easily and simply removed by holding the fixed lever 7212 (see Figure 10) and handle 74 of the fire extinguisher 72 with both hands and lifting it toward you, 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] The fire extinguisher drawer structure with the upper and lower integrated side door will be described in more detail below. In this description, reference will be made to Fig. 16, which shows a fire hydrant device with a fire extinguisher drawer structure with the upper and lower integrated side door, Fig. 17, which shows the drawer body side of the fire extinguisher drawer structure of Fig. 16, and Fig. 18, which shows the operation of drawing out the fire extinguisher from the fire hydrant device of Fig. 16.

[0128] In the fire extinguisher drawer structure shown in Fig. 16, a side fire extinguisher door 16 is provided on the side of the second housing 11b, and is integrated and can be freely pulled out. As shown in Fig. 17, an upper drawer body 32 (32-1) and a lower drawer body 32 (32-2) are provided inside the side fire extinguisher door 16, separated into upper and lower two stages, and the right ends on the depth side are connected vertically by a support member 1620, and two fire extinguishers 72 are placed horizontally on the upper and lower two stages.

[0129] The details of the upper fire extinguisher drawer structure and the lower fire extinguisher drawer structure in this embodiment are the same as those of the embodiment shown in Figures 8 to 12, except for the side fire extinguisher door 16 that is integrated at the top and bottom, so the same symbols are used and their explanations are omitted.

[0130] In the fire hydrant device equipped with the fire extinguisher drawer structure of this embodiment, when a road user wants to use a fire extinguisher, the door handle 1611 of the side fire extinguisher door 16 is pulled forward (in the -X direction) to release the lock, and 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 outward from the upper drawer opening 34 (34-1) and the lower drawer opening 34 (34-2).The fire extinguisher 72 can then be simply and easily removed by holding the fixing lever 7212 (see Figure 10) and the handle 74 of the fire extinguisher 72 with both hands and pulling it forward (in the +Z direction) while lifting it up, whether it is 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.

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

[0132] The fire extinguisher drawer structure of this embodiment is simplified by not providing an upper drawer mechanism but only a lower drawer mechanism.

[0133] As shown in Figure 19, the drawer body side of the fire extinguisher drawer structure is provided with an upper drawer body 32 (32-1) and a lower drawer body 32 (32-2) separated into two upper and lower stages inside the side fire extinguisher door 16, but the upper drawer body 32 (32-1) only has a stand 38 (38-1) and is not provided with the body guide rails and rollers that make up the drawer mechanism, while the lower drawer body 32 (32-2) is provided with the lower body guide rails 36 (36-2) and rollers 40 that make up the lower drawer mechanism. The stand 38 (38-1) is reinforced by a beam member 3813.

[0134] Corresponding to the drawer body side of such a fire extinguisher drawer structure, on the housing side, as shown in Figure 20, for the fire extinguisher storage section 50c of the second housing 11b, which is divided into an upper and lower virtual fire extinguisher storage section 5010 and a lower fire extinguisher storage section 5020, the upper fire extinguisher storage section 5010 is not provided with housing guide rails or the like that constitute the drawer mechanism on the housing side, and 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 drawer mechanism.

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

[0136] [i. Fire extinguisher box embodiment] The structure of a fire extinguisher box with a fire extinguisher drawer structure in which a fire extinguisher is stored horizontally will be described in more detail. In this description, reference will be made to Fig. 21, which shows an embodiment of a fire extinguisher box with a fire extinguisher drawer structure, and Fig. 22, which shows the operation of drawing out a fire extinguisher in the fire extinguisher box of Fig. 21. Fig. 22(A) shows the state in which the fire extinguisher is drawn out by operating the upper side drawer door, and Fig. 22(B) shows the state in which the fire extinguisher is drawn out by operating the lower side drawer door.

[0137] As shown in Figure 21, the fire extinguisher box 100 of this embodiment corresponds to a 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 surface is closed. Since a fire extinguisher drawer structure similar to that of the fire hydrant device 10 is provided inside the housing 1100 of the fire extinguisher box 100, it is designated by the same reference numeral and description thereof will be 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, divided into two levels, upper and lower.

[0139] When a road user uses a fire extinguisher, the lock is released by pulling the upper door handle 1611 of the upper side fire extinguisher door 16 (16-1) forward (in the -X direction) according to the number "1" on the operation sequence display 1615, and the upper drawer body 32 (32-1) with the fire extinguisher 72 placed horizontally is pulled outward from the upper drawer opening 34 (34-1) as shown in Figure 22 (A).

[0140] At this time, as shown in Figure 8 (A), the abutment piece 1618 formed at the lower end of the upper side fire extinguisher door 16 (16-1) abuts against the inner surface of the upper end of the lower side fire extinguisher door 16 (16-2), so that the lower side fire extinguisher door 16 (16-2) is also pulled out from the lower pull-out opening 34 (34-2) in conjunction with the pulling-out operation of the upper side fire extinguisher door 16 (16-1), making it possible to remove the two fire extinguishers 72 placed horizontally.

[0141] For example, a road user can simply and easily remove the fire extinguisher 72 by holding the fixed 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 toward them.

[0142] Next, when a road user wants to remove the fire extinguisher 72 from the lower drawer body 32 (32-2), since the upper drawer body 32 (32-1) gets in the way, the road user can simply and easily remove the fire extinguisher 72 by, for example, pushing the upper side fire extinguisher door 16 (16-1) closed, and then holding the fixed lever 7212 (see Figure 10) and handle 74 of the fire extinguisher 72 placed horizontally in the lower drawer body 32 (32-2) with both hands and lifting it toward them.

[0143] In addition, since the fire extinguisher 72 can be pulled out to the outside of the side of the housing of the fire hydrant device 10, the guard passage 35 in the front direction of the housing through which evacuees pass is not restricted, and the fire extinguisher 72 can be pulled out and taken out without obstructing passage through the guard passage 35.

[0144] Figure 22 (B) shows the case where a road user pulls out the lower side fire extinguisher door 16 (16-2) while the upper side fire extinguisher door 16 (16-1) is closed. By pulling the lower door handle 1612 forward (in the -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 out alone from the lower drawer opening 34 (34-2) to the outside.

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

[0146] [j. Modifications of the present invention] Modifications of the fire hydrant device according to the present invention will now be described. In addition to the above-described embodiment, 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 device) The above embodiment has been given as an example of a fire hydrant device with a stationary structure in which the housing is attached and fixed to the top of a stand installed on the road surface of the guard passage close to or abutting the tunnel wall side, but this is not limited to this. Similarly, a wall-mounted fire hydrant device in which the housing is attached and fixed to the front part on the road side of a stand installed on the tunnel wall surface above the road surface of the guard passage may also be used, in which a side door is provided on the side of the housing and the side door can be opened to allow work inside the housing from the outside side.

[0148] (If the tunnel wall has a cross section other than a circular cross section) In the above embodiment, the tunnel cross-sectional shape is circular, but if the tunnel cross-section is other than circular, such as a tricentric circle, the present invention can be applied by taking the horizontal line at the position where the horizontal width of the tunnel cross-sectional shape is widest as the tunnel center line SL1 in the above explanation.

[0149] (Fire hydrant device structure compatible with thinning) In the fire hydrant device in the above embodiment, the width of the first and second housings is increased to accommodate the reduction in thickness of the fire hydrant device, thereby ensuring the internal volume that would have been reduced by the reduction in thickness. However, the vertical width of the first and second housings may also be increased to ensure the internal volume that would have been reduced by the reduction in thickness.

[0150] (Downward diagonal drawer mechanism) The drawer mechanism of the above embodiment may support the drawer body movably in a direction inclined diagonally downward from the horizontal direction of the drawer. The diagonally downward angle may be any angle, but for example, by supporting the drawer body movably in a direction inclined diagonally downward from the horizontal direction at an angle of about 2 to 3 degrees, when a road user releases the lock of the side fire extinguisher door with the door handle, the fire extinguisher can be pulled out with a light force to be exposed to the removal position, and further, the weight of the drawer body in which the fire extinguisher is placed vertically acts as a force to move it in the diagonal direction, so that the fire extinguisher can be moved to the removal position even when the door handle is released. Here, "horizontal" does not only mean being parallel to the horizontal indicated by a spirit level, i.e. perpendicular to the vertical, but also includes being approximately parallel to the tunnel road surface, and at least being approximately parallel to the road surface corresponding to the installation location when the road surface has a varying gradient, and further includes being approximately parallel to the lateral direction (left-right direction, width direction) of the installed housing or approximately perpendicular to the longitudinal direction (up-down direction, height direction) of the housing when it is installed when the width direction of the housing is roughly along such parallel lines. Also, a "horizontal line" is a line approximately parallel to the "horizontal" direction.

[0151] (Drawer mechanism) The drawer mechanism of the fire extinguisher drawer structure in the above embodiment is a drawer mechanism that uses two guide rails, with the drawer guide rail of the drawer body slidably fitted into the fixed housing guide rail, but it may also be a drawer mechanism that uses 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 the objects and advantages thereof, and is not limited to the numerical values ​​shown in the above embodiments. [Explanation of symbols]
