Description

[Technical Field]

[0001] The present invention relates to a fire extinguisher storage device that is installed flush with a guard passageway and stores a fire extinguisher in a removable manner, and to emergency equipment equipped with said device. [Background technology]

[0002] 2. Description of the Related Art Conventionally, emergency equipment is installed in tunnels on expressways and motorways to protect people and vehicles from fire accidents that occur inside the tunnel.

[0003] Such emergency equipment includes fire detectors, manual reporting devices, and emergency telephones for fire monitoring and reporting, as well as fire hydrants and fire extinguisher boxes for extinguishing fires and preventing the spread of fires, and water spray equipment that sprays fire-fighting water from water spray heads to protect the tunnel body from fires.The emergency equipment is monitored and controlled by connecting it to a transmission line from a disaster prevention receiving panel installed in the monitoring center.

[0004] For example, fire hydrant devices are installed at 50-meter intervals along the side walls facing the guard passages inside the tunnel, and each housing has a fire hydrant door that can be opened freely, and contains a hose with a nozzle at the end and various valves.

[0005] In addition, the fire extinguisher boxes are installed either integrally with the fire hydrant equipment or stand alone, and are installed, for example, at intervals of 50 meters along the side walls facing the guard passages installed inside the tunnel.

[0006] The inspector's passage is set up as a side wall passage about one meter higher than the road surface, allowing inspectors to safely inspect various equipment installed inside the tunnel, including fire extinguisher boxes, without interfering with vehicle traffic inside the tunnel.

[0007] In the event of a vehicle accident involving a fire, the driver or other user of the accident vehicle can open the fire extinguisher door of the fire extinguisher box, remove the fire extinguisher, and carry out fire extinguishing work. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-181057 [Patent Document 2] Japanese Patent Application Laid-Open No. 2008-055024 [Patent Document 3] Japanese Patent Application Laid-Open No. 2009-285126 [Patent Document 4] Japanese Patent Application Publication No. 2017-202232 [Patent Document 5] Japanese Patent Application Laid-Open No. 2017-209145 [Patent Document 6] Japanese Patent Application Laid-Open No. 2016-059790 Summary of the Invention [Problem to be solved by the invention]

[0009] However, in urban tunnels constructed using the shield tunneling method, etc., the structure does not allow fire extinguisher boxes to be embedded in the tunnel walls, so fire extinguisher boxes must be embedded in the side (wall) of the guard passage.

[0010] However, when a conventional fire extinguisher box with a front-opening door is installed in the guard's passage, there is a problem that when the fire extinguisher door opens, it will jump out onto the road beyond the building limit.

[0011] On the other hand, even if this problem could be solved, if the fire hydrant box were installed flush with the wall of the guard's passage facing the road inside the tunnel, when a vehicle fire occurs and the vehicle stops in front of the fire extinguisher door, the stopped vehicle may get in the way and make it impossible to open the door and take out the fire extinguisher. Furthermore, even if it were possible to operate the fire extinguisher door from the guard's passage, it would require the guard to bend down and reach out to open it, which could make it difficult to take out the fire extinguisher from the box.

[0012] An object of the present invention is to provide a fire extinguisher storage device that allows a fire extinguisher to be easily and simply removed by opening the door of the fire extinguisher box, and emergency equipment equipped with said device. [Means for solving the problem]

[0013] (Fire extinguisher storage device) The present invention provides a fire extinguisher storage device that is embedded under the road surface of a guard passageway above the road surface of a tunnel and has a fire extinguisher storage unit that stores a fire extinguisher, The fire extinguisher storage area is a front door opening formed on the road side of the tunnel when installed; A front door that opens and closes the front door opening; a fire extinguisher removal structure that allows the fire extinguisher stored in the fire extinguisher storage section to be removed by tilting the upper side of the fire extinguisher forward without contacting the front door in an open state; The present invention is characterized by the following features.

[0014] (Fire extinguisher access structure on the front door) The fire extinguisher removal structure is provided on the door surface of the front door on the fire extinguisher storage compartment side.

[0015] (Fire extinguisher access structure installed on a front door with a fixed door and a sliding door) The front door is a fixed door fixed to the bottom; A plurality of sliding doors arranged on the upper side so as to be freely opened and closed in the vertical direction; Equipped with The fire extinguisher removal structure is provided on the door surface of the fixed door or any of the sliding doors that is located closest to the fire extinguisher storage section when in the open state.

[0016] (Guide roller or hollow pipe) The fire extinguisher removal structure includes a guide roller or a hollow pipe.

[0017] (Emergency equipment) In another aspect of the present invention, there is provided an emergency facility comprising: The fire extinguisher storage device is characterized in that it is embedded in an embedded portion below the road surface of a guard passageway located above the road surface of a tunnel. [Effects of the Invention]

[0018] (Basic effect) The present invention relates to a tunnel fire extinguisher box, which is installed by recessing it in the guard's passage along the tunnel wall and which contains a housing containing a fire extinguisher, a front door at the front door opening of the housing on the road side, which has a fixed door fixed at the bottom and multiple sliding doors arranged on the top so that they can slide open and close in the vertical direction, and an upper door at the door opening of the housing on the guard's passage side, which is arranged so that it can be opened both front and rear. In the front-opening arrangement, the upper door is arranged so that it can be opened and closed around the rear edge of the upper door as an axis, and in the rear-opening arrangement, it is arranged so that it can be opened and closed around the front edge of the upper door as an axis.Therefore, in the event of a fire caused by a vehicle accident, a user can slide open the front door facing the road and open the upper door in the front-opening position so that it can be opened in the depth direction, which opens the upper front and top of the fire extinguisher box widely, and the fire extinguisher stored in the housing can be easily and simply removed to extinguish the fire.

[0019] In addition, the front door consists of three doors: a fixed door and at least two sliding doors. When the sliding doors are slid open, the upper two-thirds of the fixed door is opened, exposing approximately the upper half of the fire extinguisher stored inside the housing. This ensures a sufficient door opening area, making it easy to remove the fire extinguisher from the road side.

[0020] In addition, if a vehicle stops in front of the fire extinguisher box and the user cannot operate it from the road side, the user can climb onto the guard passage, bend down and open the upper door towards the road from the rear, thereby simply and easily removing the fire extinguisher from the housing and putting out the fire without being obstructed by the stopped vehicle.

[0021] In addition, when the upper door is opened toward the road, it functions as a fence, which prevents the user from falling onto the road when removing the fire extinguisher from the upper opening, and also prevents the fire extinguisher from being removed from inside and dropped onto the road.

[0022] (Effect of front and rear opening mechanisms) The upper door is provided with a front-opening mechanism operated by a front-opening handle and a rear-opening mechanism operated by a rear-opening handle. When the upper door is in the closed position, the front-opening mechanism engages the top of the front door to hold it in the closed position. When the front-opening handle is operated, the front door is released from its engagement, causing it to slide down and open to the front, and the top surface can be opened by operating the upper door to open from the front. When the upper door is in the closed position, the rear-opening mechanism engages with the housing side to hold it in the closed position. When the rear-opening handle is operated with the upper door in the closed position, the engagement with the housing side is released. Since the top can be opened by operating the upper door from the rear, when operating from the road side, the front door can be slid open and the upper door can be opened forward by lifting up the front opening handle, which is located in a position that can be operated from the road, and when operating from the guard passage side, the upper door can be opened from the rear by lifting up the rear opening handle, which is located in a position that can be operated from the guard passage.In the event of a fire caused by a vehicle accident, the user can easily and reliably open the front door and / or upper door by operating the handle according to the situation at the location where the fire extinguisher box is installed, and take out the fire extinguisher to put out the fire.

[0023] (Effect of detailed structure of front and rear opening mechanisms) The front-opening mechanism is arranged in front of the upper door, and includes a first door opening / closing mechanism that inserts a first shaft member taken out from both sides of the handle body into a rear shaft hole of the front door when the front-opening handle is not operated, thereby locking the front door, and pulls the first shaft member out of the rear shaft hole when the front-opening handle is operated, thereby unlocking the upper door; and a second door opening / closing mechanism that detachably supports a second shaft member supported on the underside of both front ends of the upper door by a ball catch mechanism or a semi-cylindrical bearing portion arranged on the housing side. The rear-opening mechanism is arranged in front of the upper door when the front-opening handle is not operated, thereby locking the front door. The third door opening / closing mechanism has a third shaft member removed from both sides of the dolly body that is inserted into the shaft hole on the housing side to lock the upper door in the closed position, and a rear-opening handle that pulls the third shaft member out of the shaft hole in the housing to release the lock on the upper door, allowing the door to be opened rearward around the second shaft member of the second door opening / closing mechanism.As a result, the first and third door opening / closing mechanisms can attach and detach the shaft member to the shaft hole on the fixed side by operating the handle, thereby achieving in a single structure the closed retention function that locks the door in the closed position and the function as a rotating shaft that rotates the upper door, which simplifies the mechanism structure.

[0024] In addition, the second door opening and closing mechanism also has a single structure that functions as a closed retention function that keeps the upper door in the closed position when it is closed, and as a rotating axis when the upper door is opened from the rear, making the mechanism structure simple.

[0025] (Effect of a front door with a sliding door behind a fixed door) In addition, the front door has a plurality of sliding doors arranged behind the fixed door so that they can be freely slid open and closed in the vertical direction, so that the sliding doors of the front door slide down inside the fixed door to open, preventing road users from having their toes pinched by the falling sliding doors and enabling the front door to be opened safely.

[0026] (Effect of a front door with a sliding door placed in front of a fixed door) In addition, the front door has multiple sliding doors arranged in front of the fixed door so that they can be slid open and closed in the vertical direction. In this case, a shock absorber is provided to absorb the impact of the sliding doors falling, preventing road users' feet from getting caught in the falling sliding doors.

[0027] (Effect of the front door with a sliding door stored inside the fixed door) Furthermore, the front door provided with a plurality of sliding doors is arranged so as to be able to slide open and close in the vertical direction so that the sliding door located above is stored inside the fixed door and the other sliding door located above it is stored inside the sliding door, so that road users will not have their toes caught by the sliding door as it falls, and the front door can be opened safely.

[0028] In addition, guide posts are erected on both the left and right sides inside the fixed door and the sliding door, and the tips of the guide posts are positioned to abut and support the back surface of the upper door when it is closed, allowing the multiple sliding doors located above the fixed door to slide open and close smoothly. Also, by supporting the upper door with the tips of the guide posts, it is possible to reliably support a person even when standing on the upper door.

[0029] (Effect of lifting up the sliding door) Furthermore, the multiple sliding doors are provided with a door connection structure that connects and pulls up the lower sliding doors when the upper sliding door is pulled up, so that when closing the open upper door, by pulling up the upper sliding door, the lower sliding doors can be pulled up one after the other by the door connection structure and held in the closed position.

[0030] (Effect of the divided nameplate on the front door of the fire extinguisher box) Furthermore, because the letters and / or graphics indicating a fire extinguisher are arranged vertically on the surface of the multiple sliding doors that make up the front door, which are divided vertically, the nameplate text indicating a fire extinguisher can be arranged in a sufficiently large character size that is clearly visible. This is because, in order to increase the opening area when the multiple sliding doors that make up the front door are dropped open and make it easier to remove a fire extinguisher, it is necessary to increase the number of sliding doors, for example, to five. However, as the number of doors increases, the vertical width of the sliding door becomes narrower, and if the nameplate text indicating "fire extinguisher" is arranged horizontally on a single sliding door, the character size becomes small. Therefore, by arranging the nameplate text indicating a fire extinguisher vertically on the surface of the multiple sliding doors, the nameplate text can be arranged in a sufficiently large character size without being affected by the narrowing of the vertical width of the sliding door due to the increase in the number of doors. Furthermore, it is possible to arrange nameplate text of a sufficient size that includes a pictogram indicating a fire extinguisher in addition to the nameplate text "fire extinguisher."

[0031] (Effect of fire extinguisher removal structure) In another form of the present invention, a fire extinguisher box for a tunnel is provided with a housing that is recessed into the guard passage along the tunnel wall and contains a fire extinguisher, a front door at the front door opening of the housing on the road side, which has a fixed door fixed at the bottom and multiple sliding doors arranged on the top that can slide open and close in the vertical direction, an upper door at the door opening of the housing on the guard passage side, which is arranged to be able to open both front and rear, and a fire extinguisher removal structure that allows the fire extinguisher stored in the housing to be tilted diagonally upward and forward when the front door and upper door are open, so that although the fire extinguisher is heavy at around 10 kilograms, when it is removed from the open front door, it can be tilted forward and pulled out in this position, eliminating the need for road users to directly lift the heavy fire extinguisher and making it possible to simply and easily remove the fire extinguisher from the housing.

[0032] (Effect of guide rollers for fire extinguisher removal) In addition, the fire extinguisher removal structure is designed so that when the topmost sliding door that makes up the front door is open, a guide roller is positioned on the inner upper edge of the inner sliding door, so when the fire extinguisher is pulled out by tilting it forward, the fire extinguisher can be pulled out while being placed against the guide roller, making it possible to simply and easily remove the fire extinguisher from inside the housing.

[0033] (Effect of fire extinguisher removal structure using two hollow pipes) In addition, the fire extinguisher removal structure is designed so that when the multiple sliding doors that make up the front door are open, a large-diameter hollow pipe is arranged on the inside of the lower part of the inner sliding door and a small-diameter hollow pipe is arranged on the inside of the upper part.Therefore, when the multiple sliding doors that make up the front door are open and the fire extinguisher is pulled out forward, the fire extinguisher hits the large-diameter hollow pipe on the bottom of the door and the small-diameter hollow pipe on the top of the door, causing it to tilt diagonally, and by pulling the fire extinguisher out along the large-diameter hollow pipe and the upper small-diameter guide pipe while it remains tilted, the fire extinguisher can be easily and simply removed from inside the housing.

[0034] (Effect of the cylindrical base structure for removing the fire extinguisher) In addition, the fire extinguisher removal structure comprises a cylindrical base for storing the fire extinguisher, a pivot shaft provided at the bottom of the cylindrical base for rotating the cylindrical base back and forth, and guide rollers arranged circumferentially inside the cylindrical base. Therefore, when removing the fire extinguisher from inside the housing, the fire extinguisher can be easily tilted forward because it is stored in the cylindrical base supported by the pivot shaft, and the guide rollers are arranged circumferentially inside the cylindrical base, making it possible to easily remove the fire extinguisher from the cylindrical base.

[0035] In addition, in the normal state when the front door and top door are closed, the fire extinguisher stored in the cylindrical base is stored tilted toward the rear side within the housing because the bottom of the cylindrical base is supported by a rotating shaft, and it will not fall forward.As a result, the opening of the multiple sliding doors that make up the front door due to their own weight falling is not hindered by the fire extinguisher tilting forward.

[0037] [Outline of tunnel emergency equipment] Figure 1 is an explanatory diagram showing emergency tunnel equipment, including a fire extinguisher box, installed in a tunnel for expressways. As shown in Figure 1, the inside of a tunnel 10 constructed using the shield tunneling method is covered with a cylindrical tunnel wall 12, and a road 15 is provided by separating it with a deck slab 17. In this example, the road 15 has two lanes in one direction.

[0038] A guard passage 14 is provided along the tunnel wall 12 on the left side of the road 15 separated by the deck 17, and the internal space below the guard passage 14 is used as a duct 22 in which electrical conduits and the like are laid. The guard passage 14 is, for example, 90 centimeters high and 70 centimeters wide.

[0039] The underside of the deck 17 on which the road 15 is formed is divided into multiple sections laterally across the tunnel, and for example, the section located below the guard passage 14 is used as a maintenance passage 23, which is also used as an emergency evacuation passage in the event of a fire inside the tunnel. A water supply main 24 is laid in the maintenance passage 23.

[0040] Fire hydrant equipment 16 is installed every 50 meters along the length of tunnel 10. Each fire hydrant equipment 16 is equipped with a fire hydrant storage box 18 containing a hose and a fire extinguisher box 20 containing, for example, two fire extinguishers. A water discharge control mechanism storage section 25 is installed separately from the fire hydrant storage box 18 in the management passage 23.

[0041] The fire extinguisher box 20 and the fire hydrant storage box 18 are placed in a fire hydrant recess that is carved into a box shape extending from the road surface of the guard passage 14 to the wall on the road 15 side. Although the fire extinguisher box 20 may be placed separately from the fire extinguisher storage box 18, the following explanation will be given taking the case where it is installed integrally with the fire hydrant storage box 18 as an example.

[0042] [Fire hydrant facilities] (External structure of fire hydrant storage box) Figure 2 is an explanatory diagram showing a fire extinguisher box together with a fire hydrant storage box, Figure 3 is an explanatory diagram showing a fire extinguisher box with the upper door opened from the front and slid down to open, and Figure 4 is an explanatory diagram showing a fire extinguisher box with the upper door opened from the rear.

[0043] As shown in Figure 2, the fire extinguisher box 20 is embedded in the internal space below the road surface of the guard passage 14. The fire extinguisher box 20 has a front door 30 provided in the center of the front of a housing 31, and the front door 30 has a fixed door 35 disposed on the lower side, and two sliding doors 36a, 36b disposed above the fixed door 35 so as to be able to slide open and close in the vertical direction.

[0044] Additionally, an upper door 32 having the same width as the front door 30 is disposed on the upper surface of the fire extinguisher box 20 facing the road surface of the guard passage 14. The upper door 32 can be opened from the front as shown in FIG. 3 or from the rear as shown in FIG. 4.

[0045] Here, the front-opening of the upper door 32 means that it opens and closes by rotating upward around the rear edge on the depth side of the upper door 32 as an axis, as shown in Figure 3, and the rear-opening of the upper door 32 means that it opens and closes by rotating upward around the front edge in front of the upper door 32 as an axis, as shown in Figure 4.

[0046] As shown in Figure 2, in the normal state, the top sliding door 36a of the front door 30 is locked in the closed state by the upper door 32 which is in the closed state. When a user operates the front door 30 from the road 15 side, by opening the front opening handle 34, the sliding door 36a is unlocked from the upper door 32. As shown in Figure 3, the sliding doors 36a and 36b fall to the back side of the fixed door 35 due to their own weight, opening the front door opening of the fire extinguisher box 20. Also, by opening the upper door 32 from the front, the top door opening of the fire extinguisher box 20 is opened.

[0047] The front door 30 is opened by dropping two sliding doors 36a and 36b behind the fixed door 35. If the fixed door 35 and the sliding doors 36a and 36b are the same height, then the upper two-thirds of the front door 30 will be open. By increasing the opening area of the front door 30, it becomes easier to remove the fire extinguisher stored in the housing 31 from the road 15 side.

[0048] In this embodiment, the front door 30 is divided into three parts by a total of three doors: the fixed door 35 and two sliding doors 36a, 36. However, by increasing the number of divisions, the opening area when the front door 30 is opened can be further enlarged, making it easier to remove the fire extinguisher stored in the housing 31 from the road 15 side.

[0049] In addition, when a user operates the device from the monitor passage 14 side, opening the rear-opening handle 38 releases the upper door 32 from the housing 31, and by opening the upper door 32 from the rear as shown in Figure 4, the top door opening of the fire extinguisher box 20 is opened.

[0050] As shown in Figure 2, a reporting device panel door 42 is provided on the front right side of the fire extinguisher box 20. The reporting device panel door 42 is provided with a red indicator light 44, a transmitter 45, a telephone jack 46, and a response lamp 48. The red indicator light 44 is always lit, allowing the location of the fire hydrant equipment to be identified from a distance. In the event of a fire, when the transmitter 45 is pressed to turn on the push-button switch, a transmission signal is sent to the fire receiver in the monitoring room, issuing a fire alarm. In response to this, a response signal is sent from the fire receiver, turning on the response lamp 48 and causing the red indicator light 44 to flash.

[0051] [Front door and upper door opening / closing mechanism] Figure 5 is an explanatory diagram showing the fire extinguisher box from the front and top with the front and top doors closed, Figure 6 is an explanatory diagram showing the front door side of the fire extinguisher box as seen from the inside, Figure 7 is an explanatory diagram showing the functional configuration of the first door opening and closing mechanism that releases the front door from the top door and allows it to slide open, and Figure 8 is an explanatory diagram showing a cross section of the second door opening and closing mechanism that engages the top door in a closed position and opens it to the rear.

[0052] (Front and rear opening mechanisms) As shown in Figures 5 and 6, the upper door 32 arranged at the top door opening of the fire extinguisher box 20 has a front-opening mechanism operated by a front-opening handle 34 and a rear-opening mechanism operated by a rear-opening handle 38.

[0053] When the upper door 32 is in the closed position as shown, the front-opening mechanism of the upper door 32 engages the top of the sliding door 36a, which is located at the top of the front door 30, with the first door opening / closing mechanism 60 to hold it in the closed position; when the front-opening handle 34, which is positioned facing downward on the front edge of the upper door 32, is lifted up (opened), the sliding door 36a is released from its engagement with the upper door 32, causing the two sliding doors 36a, 36b to slide down to the back of the fixed door 35, opening the front door opening that was closed by the two sliding doors 36a, 36b.

[0054] In addition, when the upper door 32 is opened from the front in the depth direction, the second door opening / closing mechanism 62 releases its engagement with the housing 31, and the upper door 32 is opened from the front using the axial center line 85 of the third door opening / closing mechanism 64 arranged on the depth side of the upper door 32 as the rotation axis, thereby opening the top surface.

[0055] When the upper door 32 is in the closed position, the rear-opening mechanism of the upper door 32 engages the upper door 32 with the housing 31 side using the third door opening / closing mechanism 64 to hold it in the closed position, and when the rear-opening handle 38 provided on the rear edge side of the upper door 32 is operated, the engagement with the housing 31 side is released, and the upper door 32 is opened from the rear using the axial center line 75 of the first door opening / closing mechanism 60 and the second door opening / closing mechanism 62 provided on the front edge side of the upper door 32 as the rotation axis, thereby opening the top surface.

[0056] (First door opening / closing mechanism) As shown in Figures 4 to 7, the first door opening / closing mechanism 60, which is arranged at the top center of the topmost sliding door 36a of the front door 30 and at the center of the front edge of the upper door 32, has an axis member (first axis member) 66 protruding on both sides from the handle body 34a on the back side of the front-opening handle 34, and the tip of the axis member 66 is inserted into an axis hole of a bearing portion 68 fixed to the back surface of the sliding door 36a, thereby engaging the sliding door 36a with the upper door 32 and holding it in the closed position.

[0057] The sliding door 36b located below the sliding door 36a is connected to the back side of the sliding door 36a so as to be suspended when the sliding door 36a is engaged with the upper door 32 and held in the closed position, thereby being held in the closed position.

[0058] When the front-opening handle 34 is lifted up, the shaft member 66 of the handle body 34a is pulled inward and comes out of the shaft hole of the bearing portion 68, thereby releasing the lock on the sliding door 36a, and the sliding doors 36a and 36b slide under their own weight and fall to the back side of the fixed door 35, opening the upper part of the front face.

[0059] As shown in FIG. 7(A), the details of the first door opening / closing mechanism 60 are as follows: one end of a pair of bent links 78 is connected to a movable fulcrum 80 within the handle main body 34a, the bent position of the link 78 is fixed to the handle main body 34a side as a fixed fulcrum 82, and the other end of the link 78 is connected to a fulcrum 86 at the shaft end of the shaft member 66 as a sliding fulcrum 84; and further, the movable fulcrum 80 is biased upward as shown by a spring 88.

[0060] When the front-opening handle 34 is not operated, the link 78 rotates outward under the force of the spring 88, fitting the shaft member 66 into the shaft hole of the bearing portion 68 and locking the sliding door 36a to the upper door 32.

[0061] When the front-opening handle 34 is lifted up, as shown in Figure 7(B), the moving fulcrum 80 moves downward against the spring 88 via a link mechanism not shown, causing the link 78 to rotate inward and pull the shaft member 66 inward, thereby removing the tip of the shaft member 66 from the shaft hole of the bearing portion 68, releasing the lock on the sliding door 36a, causing the sliding door 36a to slide down together with the sliding door 36b under their own weight and opening the front door opening.

[0062] The first door opening / closing mechanism 60 is not limited to the link mechanism of FIG. 7, but may include any suitable link mechanism that lifts up the front-opening handle 34 to pull the shaft member 66 inward and remove it from the shaft hole of the bearing portion 68.

[0063] (Second door opening / closing mechanism) As shown in Figures 5 and 6, the second door opening / closing mechanism 62, which is arranged at both ends of the front edge of the upper door 32, has an axial member (second axial member) 72 cantilevered inside the upper door 32 so that it is floating above the back surface of the door, and is arranged so that it can be attached and detached from above to a bearing portion 70 fixed to the housing 31 side.

[0064] The second door opening / closing mechanism 62 is disposed on the same axial center line 75 as the first door opening / closing mechanism 60, and the axial center line 75 serves as the center of rotation when the upper door 32 is opened from the rear.

[0065] As shown in detail in Figure 8, the shaft member 72 is cantilevered by a support member 73 on the inside of the upper door 32, and is rotatably fitted into a bearing portion 70 fixed to the housing 31 side when the upper door 32 is closed.

[0066] The bearing portion 70 is provided with a semi-cylindrical open bearing member 71 that opens upward, and a pair of ball catches 77 made of an elastic material such as rubber are arranged on the upper side of the open bearing member 71, thereby forming a ball catch mechanism that supports the shaft member 72 from above in a manner that allows it to be freely attached and detached to the open bearing member 71.

[0067] A slit 79 is formed at the upper end of the sliding door 36a, and a gap is formed that allows the support member 73 supporting the shaft member 70 to rotate when the upper door 32 is opened from the rear.

[0068] In addition, instead of providing a ball catch 77 in the bearing portion 70, a semi-cylindrical open bearing member 71 that opens upward may be provided, and the open bearing member 71 may receive the shaft member 72 from above in a detachable manner and support it so that it can rotate freely.

[0069] (Third door opening / closing mechanism) As shown in Figure 5 (B), the third door opening / closing mechanism 64, which is located in the center of the rear edge of the upper door 32, has an axial member (third axial member) 74 protruding on both sides from the handle body 38a on the back side of the rear-opening handle 38, and the tip of the axial member 74 is inserted into an axial hole of a bearing portion 76 fixed to the inner back surface of the housing 31, so that the rear edge side of the upper door 32 is engaged with the housing 31 side and held in the closed position.

[0070] When the rear-opening handle 38 is lifted up (opened), the shaft member 74 is pulled inward and comes out of the shaft hole of the bearing portion 76, thereby releasing the lock on the rear edge side of the upper door 32 and allowing the upper door 32 to be opened rearward around the shaft center line 75 (see Figure 6) formed by the first door opening / closing mechanism 60 and the second door opening / closing mechanism 62 arranged on the front edge side of the upper door 32, thereby opening the upper door opening.

[0071] The third door opening / closing mechanism 64 that releases the lock of the upper door 32 by lifting up the rear-opening handle 38 has the same mechanical structure as the first door opening / closing mechanism 60 shown in FIG.

[0072] [Opening the upper and front doors from the road side] As shown in Figure 3, when a road user lifts up the front opening handle 34, the uppermost sliding door 36a of the front door 30 is released from its lock, and the sliding door 36a slides down together with the sliding door 36b under its own weight and is stored behind the fixed door 35, and the front door 30 is opened.

[0073] Next, when a road user performs a front-opening operation to open the upper door 32 in the depth direction, the shaft members 66 arranged on both sides of the front edge of the upper door 32 are pulled out from the bearing portions 68, the locking of the front edge side to the housing 31 side is released, and the upper door 32 is opened forward around the shaft center line of the third door opening / closing mechanism 64 arranged on the depth side, and the upper door opening is opened.

[0074] At this time, more than half of the upper side of the fire extinguisher 50 stored in the housing 31 is exposed, and by reaching out from the road 15 side and tilting the fire extinguisher 50 forward and pulling it out diagonally forward in this state, it is not necessary to directly lift the heavy fire extinguisher 50 weighing 10 kilograms, and it can be easily and simply removed.

[0075] [Opening the upper door from the guard passage] As shown in Figure 4, when a road user operates the fire extinguisher box 20 from the guard passage 14 side, they bend down from the guard passage 14 and lift up the rear-opening handle 38, which releases the lock on the rear edge of the upper door 32 to the housing 31 side, and the upper door 32 opens rearward around the common axial center line 75 of the first door opening / closing mechanism 60 and the second door opening / closing mechanism 62 located on the front edge side, as shown in Figures 5 and 6, forming an upper opening, and road personnel can reach through the upper opening to remove the fire extinguisher 50 stored in the housing 31.

[0076] In this case, the upper door 32 opens toward the road and functions as a fence, which prevents road users from falling onto the road when removing the fire extinguisher 50 from the upper opening, and also makes it possible to prevent the fire extinguisher 50 removed from inside from being dropped onto the road.

[0077] [Front door opening and closing mechanism] (Front door opening and closing structure with a sliding door located behind a fixed door) FIG. 9 is an explanatory diagram showing the structure of the front door that slides the sliding door open and closed behind the fixed door.

[0078] As shown in FIG. 9, the opening and closing structure of the front door 30 of this embodiment is arranged so that two upper sliding doors 36a, 36b slide open and close behind the lower fixed door 35.

[0079] The top sliding door 36a has T-shaped end sliders 92 fixed vertically to the front on both sides of the door, and a guide rail 90 that opens to the back side is embedded vertically inside the door on the back side of the sliding door 36b located below the sliders 92, and by fitting the sliders 92 into the guide rails 90, the sliding door 36a can be slid freely up and down relative to the sliding door 36b.

[0080] The same is true between the central sliding door 36b and the fixed door 35; the sliding door 36b has a slider 92 with a T-shaped end fixed vertically to the front on both sides of the door, and a guide rail 90 that opens to the back side is embedded vertically inside the door on the back side of the fixed door 35 located below the slider 92; by fitting the slider 92 into the guide rail 90, the sliding door 36b can be slid freely up and down relative to the fixed door 35.

[0081] In addition, as a connecting structure for pulling up the uppermost sliding door 36a to the closed position as shown in the figure, the sliding door 36b below it is pulled up to the closed position in conjunction with the sliding door 36a. Connecting pieces 94 extend laterally from the lower ends on both sides of the sliding door 36a, and corresponding connecting support pieces 96 extend laterally from the upper ends on both sides of the sliding door 36b located below it. By stacking the sliding doors 36a and 36b so that the connecting pieces 94 fit under the connecting support pieces 96, the upper end of the sliding door 36b is connected so that it hangs from the lower end of the sliding door 36a, and by pulling up the sliding door 36a, the sliding door 36b below it can also be pulled up and held in the closed position.

[0082] The same is true for sliding door 36b and fixed door 35, with connecting pieces 94 extending horizontally from the lower ends on both sides of sliding door 36b, and corresponding connecting support pieces 96 extending horizontally from the upper ends on both sides of the fixed door 35 located below it.By stacking sliding door 36b and fixed door 35 so that connecting pieces 94 fit under connecting support pieces 96, they function as stoppers that determine the closed position when sliding door 36b is pulled up by sliding door 36a.

[0083] According to this opening and closing structure of the front door 30, when the front door 30 is closed as shown in the figure, and the sliding door 36a is released from its engagement with the upper door side by an opening operation, the sliding doors 36a and 36b slide down under their own weight and are stored on the back side of the fixed door 35.

[0084] At this time, even if a road user attempts to open the front door 30 while standing in front of the fire extinguisher box 20, the sliding doors 36a, 36b slide down and are stored behind the fixed door 35, so there is no risk of the user's feet getting caught in the sliding doors 36a, 36b as they slide down, and the front door 30 can be opened safely.

[0085] Furthermore, when closing the front door 30 that is in an open state, by manually lifting the innermost sliding door 36a upward, the sliding door 36b is also lifted in a suspended, connected state, and the sliding door 36a is engaged with the upper door 32, thereby keeping it in a closed state.

[0086] (Front door opening and closing structure with a sliding door placed in front of a fixed door) FIG. 10 is an explanatory diagram showing the opening and closing structure of the front door that slides the movable door open and close in front of the fixed door, where FIG. 10(A) shows the door structure and FIG. 10(B) shows the guide mechanism.

[0087] As shown in Figure 10(A), the opening and closing structure of the front door 30 of this embodiment is arranged so that the two upper sliding doors 36a, 36b slide open and closed in front of the lower fixed door 35.

[0088] The uppermost sliding door 36a has a rod 102 supported downward by support pieces 104 on the upper back surface of both sides of the door, and a double-structured piston 100 is fixed to the tip of the rod 102 at a position beyond the lower end of the door, and the piston 100 is slidably fitted into a cylinder 98 arranged inside the lower sliding door 36b.

[0089] The same is true between the central sliding door 36b and the fixed door 35 below it, with sliding door 36b having rods 102 supported downward from support pieces 104 on the upper back surface of both sides of the door, and a double-structured piston 100 fixed to the tip of rod 102 at a position beyond the lower end of the door, with piston 100 slidably fitted into a cylinder 98 arranged inside the lower fixed door 35. A damper 106 is incorporated into the lower part of cylinder 98, and is made up of a receiving plate 106a and a spring 106b.

[0090] As shown in Figure 10(B), a retaining cover 101 is attached to the upper opening of the cylinder 98, and a rod 102 is fitted through an axial hole in the retaining cover 101. When the rod 102 is pulled up, the piston 100 hits the retaining cover 101, thereby realizing a connecting structure that connects the doors in a hanging state.

[0091] Even with this opening and closing mechanism for the front door 30, when an opening operation is performed to release the engagement with the upper door side while the front door 30 is in the closed state as shown in Figure 10 (A), the sliding doors 36a and 36b slide down under their own weight and are stored in front of the fixed door 35.

[0092] At this time, the piston 100 sliding inside the cylinder 98 of the fixed door 35 provided at the tip of the rod of the sliding door 36b hits the damper 106 at the dropped position and its movement is suppressed, and even if a road user attempts to open the front door 30 while standing in front of the fire extinguisher box 20, the falling speed of the sliding doors 36a, 36b is suppressed by the damper 106, and there is no risk of the user's toes getting caught in the sliding doors 36a, 36b as they slide down, and the front door 30 can be opened safely.

[0093] Furthermore, when closing the front door 30 that is in an open state, by manually lifting the innermost sliding door 36a upward, the sliding door 36b is also lifted in a suspended, connected state, and the sliding door 36a is engaged with the upper door 32, thereby keeping it in a closed state.

[0094] (Front door opening and closing structure that stores a sliding door inside a fixed door) FIG. 11 is an explanatory diagram showing the opening and closing structure of the front door that slides open and closes so as to house the movable door inside the fixed door.

[0095] As shown in Figure 11, the opening and closing structure of the front door 30 in this embodiment is such that the fixed door 35 located at the bottom has a thickness that allows the sliding door 36b above it to be stored, and the sliding door 36b has a thickness that allows the sliding door 36a above it to be stored.

[0096] The fixed door 35 and the sliding doors 36a, 36b have openings at the top, allowing the door located above to be freely inserted and removed. The lower ends of the sliding doors 36a, 36b are bent outward, and the upper openings of the sliding door 36b and the fixed door 35 are bent inward, realizing a connecting structure when the doors are pulled up to a closed position.

[0097] Furthermore, guide posts 108 are erected on both sides of the door by fixed parts 110, penetrating from the inside of the fixed door 35 through the sliding doors 36a and 36b, and the tips of the guide posts 108 are located on the back side of the upper door 32, and reinforcing members 112 arranged on the back side of the upper door 32 abut against the tips of the guide posts 108. As a result, even if a load is applied by a person standing on the upper door 32, the upper door 32 is supported by the guide posts 108, making it possible to increase the strength of the upper door 32.

[0098] In addition, a damper 106 is provided at the bottom of a guide support 108 erected inside the fixed door 35. The damper 106 is composed of a receiving plate 106a and a spring 106b, and the damper 106 slows the falling speed of the sliding doors 36a and 36b as they release their engagement with the upper door 32 and slide down, thereby absorbing the impact.

[0099] [Fire extinguisher removal structure] (Fire extinguisher removal structure using door rollers) Figure 12 is an explanatory diagram showing a fire extinguisher removal structure that uses the guide rollers of the sliding door to tilt the fire extinguisher toward the road and remove it. Figure 12(A) shows the fire extinguisher in its stored state, Figure 12(B) shows the fire extinguisher in its removed state, and Figure 12(C) shows the relationship between the fire extinguisher tilt angle and the door position.

[0100] As shown in FIG. 12(A), in the fire extinguisher removal structure of this embodiment, a guide roller 118 is arranged across the width of the door on the inside of the upper part of the sliding door 36a that is located on the inside when the front door 30 is closed.

[0101] As shown in Figure 12 (B), when the front door 30 and the upper door 32 are opened to remove the fire extinguisher 50, the fire extinguisher 50 is tilted forward, and the fire extinguisher 50 tilts to a position where it hits the guide roller 118 provided on the sliding door 36a that has fallen to the open position.

[0102] Here, as shown in FIG. 12(C), the outer line 50b of the fire extinguisher 50, which has rotated forward around the rotation fulcrum 50a, comes into contact with the guide roller 118 of radius R and stops. The inclination angle α at this time is expressed as follows, where L is the horizontal distance from the rotation fulcrum 50a to the guide roller 118, H is the height to the intersection 120 between the extension of the inner side of the sliding door 36a and the outer line 50b of the fire extinguisher 50, and H1 is the height from the center of the guide roller 118 to the intersection 120. In order to position the guide roller 118 so that the outer line 50b of the fire extinguisher 50 does not come into contact with the sliding door 36a, if L, H, and H1 are constants, then tan α=(L / H)<(R / H1) The radius R of the guide roller 118 may be set so that

[0103] By satisfying this condition, the inclination angle α can be maximized so that the fire extinguisher 50 tilted toward the sliding door 36a does not come into contact with the sliding door 36a, making it easy to remove the fire extinguisher 50. Note that a hollow pipe may be used instead of the guide roller 118.

[0104] (Fire extinguisher removal structure with two hollow pipes) FIG. 13 is an explanatory diagram showing a fire extinguisher removal structure for tilting the fire extinguisher toward the road and removing it using large-diameter guide rollers and small-diameter guide rollers.

[0105] As shown in Figure 13, in the fire extinguisher removal structure of this embodiment, a large diameter hollow pipe 122 is arranged on the inside of the lower part of the sliding door 36a, which is located innermost when the front door 30 is open, across the width of the door, and a small diameter hollow pipe 124 is arranged on the inside of the upper part of the sliding door 36a across the width of the door.

[0106] In this embodiment, when the front door 30 and the upper door 32 are opened to remove the fire extinguisher 50, the fire extinguisher 50 stored in the housing 31 is tilted forward, so that the outside of the cylinder of the fire extinguisher 50 abuts both the large diameter hollow pipe 122 and the small diameter hollow pipe 124, and in this state the fire extinguisher 50 can be pulled out diagonally upward and forward, making it easier and more convenient to pull out than if the fire extinguisher 50 were lifted directly.

[0107] Instead of the large diameter hollow pipe 122 and the small diameter hollow pipe 124, a large diameter guide roller and a small diameter guide roller may be arranged.

[0108] (Fire extinguisher tilting structure with cylindrical base) Figure 14 is an explanatory diagram showing a fire extinguisher removal structure in which the fire extinguisher is stored in a rotatable cylindrical base that allows the fire extinguisher to be tilted toward the road and removed. Figure 14(A) shows the fire extinguisher in a stored state, Figure 14(B) shows the fire extinguisher in a removed state, and Figure 14(C) shows the cylindrical base removed.

[0109] As shown in Figure 14(A), in the fire extinguisher removal structure of this embodiment, a cylindrical base 114 that houses the fire extinguisher 50 is arranged so that it can be rotated freely in the forward and backward directions by a rotating shaft 116 arranged at the bottom of the housing 31.

[0110] As shown in Figure 14(C), the cylindrical base 114 is a cylindrical body that opens upward, and guide rollers 126 are arranged in the circumferential direction halfway along the cylinder. In addition, a contact member 128 made of an elastic material such as rubber is provided on the outside of the upper end located in the front of the cylindrical base 114.

[0111] 14(A), in the normal state where the front door 30 and the upper door 32 are closed, the fire extinguisher 50 stored in the cylindrical base 114 is stored in a state inclined toward the rear side around the pivot shaft 116, as shown by the fire extinguisher 50c in phantom lines. This prevents the fire extinguisher 50 from tilting forward and interfering with the sliding doors 36a, 36b sliding down to open the doors.

[0112] As shown in Figure 14 (B), when the front door 30 and the upper door 32 are opened, by pulling the fire extinguisher 50 toward you, the fire extinguisher 50 stored in the cylindrical base 114 rotates forward around the pivot axis 116 and falls over, and the abutment member 128 abuts against the sliding door 36a in the closed state, determining the inclination angle of the fire extinguisher 50. In this state, the fire extinguisher 50 can be simply and easily removed by pulling it diagonally upward and forward.

[0113] Furthermore, guide rollers 126 are arranged in the circumferential direction inside cylindrical base 114, so that fire extinguisher 50 can be smoothly removed from cylindrical base 114.

[0114] The fire extinguisher removal structure shown in Figures 12 to 14 is an example of a front door opening and closing structure in which multiple sliding doors are slid down to the rear of a fixed door, as shown in Figure 9, but it can also be applied to a front door opening and closing structure in which multiple sliding doors are slid down to the front of a fixed door, as shown in Figure 10.

[0115] [Another embodiment of the fire extinguisher box] Figure 15 is an explanatory diagram showing the appearance of another embodiment of the fire extinguisher box together with the reporting device door side, Figure 16 is an explanatory diagram showing the fire extinguisher box of Figure 15 with the front door slid open, and Figure 17 is an explanatory diagram showing the fire extinguisher box of Figure 15 with the top door opened from the rear.

[0116] (External structure of fire hydrant storage box) As shown in Figure 15, the fire extinguisher box 20 has a front door 30 provided at the front door opening 130 of the housing 31, and in this embodiment, the front door 30 has five sliding doors 36a to 36e arranged on top of a fixed door 35 so that they can be slid open and closed in the vertical direction.

[0117] Additionally, an upper door 32 having the same width as the front door 30 is disposed on the upper surface of the fire extinguisher box 20 facing the road surface of the guard passage 14. The upper door 32 of this embodiment can only be opened from the rear as shown in FIG.

[0118] As shown in FIG. 15, in a normal state, the uppermost sliding door 36a of the front door 30 is locked to the housing 31 side by the locking mechanism of the front opening handle 132, closing the front door opening 130.

[0119] On the front surfaces of the five sliding doors 36a to 36e that make up the front door 30 and on the underside of the housing 31, nameplate letters 134 indicating "fire extinguisher" are arranged in vertically divided letters together with a fire extinguisher pictogram 136. The fire extinguisher pictogram 136 is painted in white on the front surfaces of the sliding doors 36a to 36e and the housing 31, which are painted red, and the word "fire extinguisher" is written vertically in red within the white cylinder portion of the fire extinguisher histogram 136.

[0120] Here, as shown in Figure 2, when the number of divisions of the sliding doors 36a, 36b that make up the front door 30 is as few as two, the vertical width of the sliding doors 36a, 36b is sufficient, so that the nameplate letters indicating "fire extinguisher" can be placed horizontally on one sliding door 36b. However, when the number of divisions is increased so that the front door 30 is composed of five sliding doors 36a to 36e, as shown in Figure 15, the vertical width of the sliding doors becomes narrower, and it is not possible to place nameplate letters of sufficient size horizontally.

[0121] In contrast to this, in the present embodiment shown in Figure 15, the nameplate characters 134 indicating "fire extinguisher" are arranged vertically in separate parts on the five sliding doors 36a to 36e that make up the front door 30, making it possible to make the characters large enough to be easily read from a distance.

[0122] The nameplate characters 134 and the fire extinguisher pictogram 136 may be attached by attaching a sheet member on which the nameplate characters 134 and the fire extinguisher pictogram 136 are displayed, instead of being painted.

[0123] A reporting device panel door 42 is provided on the front right side of the fire extinguisher box 20, and is equipped with a red indicator light 44, a transmitter 45, and an answer lamp 48. A telephone jack is provided inside the reporting device panel door 42.

[0124] When a user operates the fire extinguisher box 20 of this embodiment from the road 15 side, opening the front opening handle 132 releases the sliding door 36a from the receiving bracket 132a on the housing 31 side, and as shown in Figure 16, the sliding doors 36a to 36e fall under their own weight to the back side of the housing 31, which is below the front door opening 130, opening the front door opening 130 of the fire extinguisher box 20.

[0125] The front door 30 is opened by dropping down five sliding doors 36a to 36e. If the vertical width of the sliding doors 36a to 36e is the same, then approximately 4 / 5 of the upper side of the front door 30 will be opened. By increasing the opening area of the front door 30, it becomes easier to remove the fire extinguisher stored in the housing 31 from the road 15 side.

[0126] In this embodiment, as shown in the embodiment of Figure 16, the upper door 32 does not open and only the front door 30 opens, but by configuring the front door 30 with sliding doors 36a to 36e and increasing the number of divisions, the opening area can be increased when the sliding doors 36a to 36e slide down and open, and as shown in Figure 3, the fire extinguisher can be easily removed from inside the housing 31 without opening the upper door 32 to the front.

[0127] In addition, when a user operates the device from the monitor passage 14 side, by holding the rear-opening handle 138 and operating to open the upper door 32, the upper door 32 can be opened from the rear as shown in Figure 17, thereby opening the top door opening of the fire extinguisher box 20.

[0128] By making the upper door 32 only rear-openable in this way, the opening and closing mechanisms of the upper door 32 and front door 30 can be simplified compared to the upper door 32 in FIG. 3 which opens both front and rear.

[0129] [Modifications of the present invention] (1st to 3rd door opening and closing mechanisms) The first to third door opening / closing mechanisms for opening and closing the front door and upper door shown in the above embodiment are examples, and any appropriate mechanism is included as long as it has the function of releasing the front door's lock and allowing it to slide open as the upper door opens forward, and of allowing the upper door to open backward while keeping the front door in the closed position.

[0130] (Fire extinguisher box placement) The above embodiment is an example of a case where a fire extinguisher box that stores two fire extinguishers is placed on one side of the fire hydrant storage box, but a fire extinguisher box that stores one fire extinguisher may also be placed on both sides of the fire hydrant storage box.

[0131] (Multiple sliding doors) Furthermore, the door structure configured with a plurality of sliding doors shown in the embodiment of Figs. 15 to 17 can be applied to doors other than fire extinguisher doors.

[0132] (others) The present invention also 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]
