Description

The present invention relates to a fire extinguisher storage device that stores a fire extinguisher and the like and includes a fire hydrant device and a fire extinguisher box installed in a tunnel.

Conventionally, fire hydrant devices have been installed as tunnel emergency equipment in tunnels such as expressways and motorways. A fire hydrant device has a fire hydrant storage compartment in a housing equipped with a forward-tiling door (fire hydrant door), in which a fire hose with a nozzle attached to the tip and valves including a fire hydrant valve are stored, and a fire hydrant door is also provided. For example, two fire extinguishers are stored in the fire extinguisher storage section. Additionally, fire hydrant devices are generally installed by cutting out boxes in the tunnel wall and embedding them at intervals of, for example, 50 meters in the longitudinal direction of the tunnel.

By the way, in tunnels made using shield construction methods, etc., it is difficult to box out the tunnel wall and embed a fire hydrant device due to the cost and labor involved, due to the structure of the tunnel body. It is necessary to install the fire hydrant system in an exposed manner in the passageway.

In addition, in order to install the fire hydrant device on the tunnel wall without removing the box, a wall-mounted structure has been proposed in which the fire hydrant device is attached and fixed to a pedestal installed on the tunnel wall. It is composed of a support portion, a posture holding member that maintains the posture of the fire hydrant device, etc. (Patent Document 2).

In addition, there are issues with wall-mounted fire hydrant devices, such as the labor and time it takes to install them on tunnel walls, so it is recommended that the fire hydrant device be exposed on a pedestal installed on the road surface of the lifeguard passageway, which is easy to install. It is being considered to have a so-called stationary structure in which the device is installed and fixed.

Japanese Patent Application Publication No. 2016-055073 Japanese Patent Application Publication No. 2020-078429

By the way, even if the fire hydrant device has a wall-mounted structure or a stationary structure, for example, two fire extinguishers are stored in the fire extinguisher storage section of the casing equipped with a fire extinguisher door, and when a fire breaks out, road users When using a fire extinguisher, the person must open the fire extinguisher door sideways (the door pivots on one side and rotate) and take out the fire extinguisher from the fire extinguisher storage compartment to extinguish the fire. If the fire extinguisher door is left open sideways after the fire extinguisher is taken out, there is a problem in that it obstructs the passage of evacuees evacuating from the lifeguard passage.

In addition, when taking out a fire extinguisher from the side opening of the fire extinguisher door, it is necessary to grasp the fixed lever at the top of the fire extinguisher and tilt it forward to take it out diagonally upward. Because it is heavy, it is difficult for vulnerable people such as women and the elderly to take out the fire extinguisher, and there is a concern that they may drop it when they try to take it out.

This problem also applies to fire extinguisher boxes installed as emergency equipment in low-rank tunnels divided by traffic volume, tunnel length, etc.

In conjunction with the fire reporting operation, the fire extinguisher is moved to the extraction position outside the side of the casing, allowing road users to take it out and extinguish the fire.

(Effects of vertical or horizontal placement of fire extinguisher)
In addition, because the fire extinguisher was placed vertically in the fire extinguisher storage area inside the casing of the fire hydrant device, the fire extinguisher that was taken out to the outside of the side of the casing was placed vertically and exposed forward and upward. Road users can take out the fire extinguisher by grasping the fixed lever at the top of the fire extinguisher and lifting it from the bottom to the top. Lifting the fire extinguisher from the bottom to the top allows you to exert force while maintaining a comfortable posture. Therefore, even vulnerable people such as women and the elderly can easily take out and use the fire extinguisher.

When moving onto the road surface, the height is such that the lower part of the box frame passes through without touching the base, so the base, the first horizontal link, the second horizontal link, and the box frame create a parallel link mechanism. The structure is simple and robust, and the lower ends of the first horizontal link and the second horizontal link are pivotally supported on the base at a predetermined height, so that the lower part of the box frame comes into contact with the base. The parallel link mechanism allows it to be moved and placed on the road surface of the observer's passage in front of it without having to do so.

(Effect of fixing mechanism of fire extinguisher moving mechanism)
Additionally, when the fire extinguisher drawer structure moves the drawer body to the pull-out position, the fire extinguisher moving mechanism releases the fixation of forward movement of the box frame and moves the box frame forward using a parallel link mechanism.

DESCRIPTION OF EMBODIMENTS Below, embodiments of a fire hydrant device and a fire extinguisher box according to the present invention will be described in detail based on the drawings. Note that the present invention is not limited to the following embodiments.

[Basic concept of embodiment]
First, the basic concept of the embodiment will be explained. Embodiments generally relate to a fire hydrant device in which a fire extinguisher is arranged or stored in a housing, a fire extinguisher storage device including a fire extinguisher, and the like.

Here, a "fire extinguisher storage device" is a type of emergency equipment installed in tunnels of expressways and motorways that are targeted for fire extinguishing. A fire hydrant equipment such as a fire hose, electrical equipment such as a red indicator light or transmitter, and a fire extinguisher are arranged or housed in the electrical door.

Further, the fire extinguisher storage device is installed in an exposed state at a predetermined height above the road surface of a lifeguard passage provided along the inner wall surface of a tunnel having a road. Here, the "predetermined height" is the height at which the fire extinguisher storage device can be installed close to or in contact with the tunnel wall, for example, when installed on the road surface of the lifeguard passage. By attaching and fixing the casing to the top of the trestle, or by attaching and fixing the casing to the front part on the road side of the trestle installed on the tunnel wall above the road surface of the lifeguard passage, the casing can be fixed at a specified height. It will be installed.

Furthermore, the term "frame" refers to a structure that supports something using pillars and beams, and includes concepts such as a support stand, a foundation, a base, a pedestal, and a base, although specific examples are not shown.

The fire extinguisher storage device of this embodiment is provided with a fire extinguisher drawer structure that moves the fire extinguisher stored in the fire extinguisher storage section in the housing from the side of the housing to an external takeout position in accordance with the operation of a predetermined switch. When a road user uses a fire extinguisher to extinguish a fire, the fire extinguisher is placed in the direction of the side of the casing of the fire extinguisher storage device without obstructing traffic through the lifeguard passage. This allows the container to be pulled out and taken out.

The "fire extinguisher drawer structure" is a structure in which the fire extinguisher stored in the fire extinguisher storage area inside the housing can be taken in and out from the side of the housing by a road user's switch operation, and its shape and structure can be arbitrary. However, for example, it is composed of a drawer opening, a fire extinguisher storage section, a drawer main body, a side fire extinguisher door, a drawer mechanism, and a drive mechanism.

Moreover, the "drawer opening" is an opening formed in the side surface of the housing on the side where the fire extinguisher is stored. Further, the "fire extinguisher storage section" is a space formed inside the casing corresponding to the drawer opening and in which a fire extinguisher is stored. Moreover, the "drawer main body" is a member on which a fire extinguisher is placed, for example, a box-shaped container or stand with an opening at the top, and is arranged in the drawer opening so that it can be freely taken out and taken out from the outside.

Moreover, the "side fire extinguisher door" is a fire extinguisher door provided on the side surface of the housing, and is provided on the drawer side of the drawer main body, and opens and closes the drawer opening as the drawer main body is taken in and out. Furthermore, the "drawer mechanism" is a mechanism that supports the drawer main body with respect to the fire extinguisher storage part so as to be movable in the pull-out direction and the retraction direction (retraction direction). A drawer mechanism such as a desk or a document locker can be used, and a guide rail fixed to the drawer body side is slidably fitted into a guide rail fixed to the housing side via a guide roller. Note that the "side fire extinguisher door" includes the concept of "fire extinguisher side door."

Further, the "driving mechanism" is a mechanism that moves the drawer main body movably supported by the drawer mechanism from at least the drawer opening to an external takeout position on the side surface of the casing in response to the operation of a switch.

The structure, function, and type of the "drive mechanism" are arbitrary, but include, for example, a rack and pinion mechanism, a pulley mechanism, a plunger mechanism, a gas damper mechanism, a feed screw mechanism, and the like.

Although the structure and function of the "rack and pinion mechanism" which is an example of the "drive mechanism" are arbitrary, for example, it is composed of a rack bar, a pinion gear, a drive source, and a control section. Here, the "rack bar" is a long rectangular rod-shaped member with a rack gear linearly formed on one side thereof, and is arranged (fixed) along the entrance/exit direction of the bottom surface of the drawer main body. It is something that

Moreover, the "pinion gear" is a small gear (small gear) that meshes with a rack gear formed on the rack bar. In addition, the "drive source" is a device that rotates a pinion gear to move the rack bar and move the drawer body in and out of the drawer opening on the side of the case, and its structure, mechanism, and type may be arbitrary, but for example, , an electrically operated motor is used.

In addition, the "control unit" of the rack and pinion mechanism is a device that controls the drive source that moves the drawer main body from the drawer opening on the side of the case in the pull-out direction or the pull-in direction by operating a switch, and its configuration and function are arbitrary. However, for example, it is composed of a takeout switch, a storage switch, a first position detector, a second position detector, and a control circuit section.

Here, the "retrieval switch" is a switch that is operated by a road user or administrator to instruct the fire extinguisher storage device to take out the fire extinguisher, and the "storage switch" is a switch that is operated by a road user or administrator to instruct the fire extinguisher storage device to take out the fire extinguisher. The "first position detector" is a device that detects when the drawer main body has reached the take-out position, and the "second position detector" is a device that indicates the storage position of the drawer main body. This is to detect the arrival of the target. Furthermore, the "control circuit unit" drives the drive source in the drawing direction of the drawer main body when the operation of the take-out switch is detected, and then drives the drive source when a detection signal is obtained from the first position detector. One that stops the drive, drives the drive source in the drawing direction of the drawer body when the operation of the storage switch is detected, and then stops the drive source when a detection signal is obtained from the second position detector. It is.

Further, the structure and function of the "pulley mechanism", which is another example of the "drive mechanism", may be arbitrary, but for example, it may be composed of a folding pulley, a string member, a winding pulley, a drive source, and a control section. .

Here, the "folding pulley" is a pulley placed at a predetermined position near the drawer opening of the fire extinguisher storage section, and the "string member" is a pulley with one end fixed to the rear end of the drawer body and the other end. This includes a metal wire that is returned to the rear end side after being wound around a folding pulley, a resin-reinforced string such as Teflon (registered trademark), a reinforced fiber string impregnated with a synthetic resin, and the like. Further, the term "take-up pulley" is, for example, a pulley that is placed at a predetermined position in the fire extinguisher storage part, the other end of the string member is fixed, and performs winding, and includes a take-up drum.

In addition, the "drive source" is a device that moves the drawer main body from the drawer opening to the external take-out position on the side of the casing by rotating the take-up pulley and winding up the string member, and refers to its structure, mechanism, Although the type is arbitrary, for example, an electrically operated motor is used.

In addition, the "control unit" of the pulley mechanism is a device that controls the drive source to be driven in the direction of pulling out the drawer body to the outside (the direction of pulling out the drawer body) by operating a switch, and its configuration and function can be changed as desired. However, for example, it is composed of a take-out switch, a position detector, and a control circuit section.

Here, the "retrieval switch" is a switch that is operated by a road user or administrator to instruct the fire extinguisher storage device to retrieve the fire extinguisher, and the "position detector" refers to the This is to detect the arrival of the sample at the take-out position. Furthermore, the "control circuit section" is a circuit that drives the drive source in the direction of pulling out the drawer body when the operation of the take-out switch is detected, and then drives the drive source when a detection signal is obtained from the position detector. It is something that stops.

In addition, in the pulley mechanism, the drive source rotates the take-up pulley to move the drawer main body from the drawer opening to the external take-out position on the side of the casing. The removed drawer main body cannot be returned to the fire extinguisher storage section in the housing by a drive source, but can be stored in the fire hydrant storage section by manually pushing the drawer main body into the housing.

Further, the "control section" of the pulley mechanism can also be used as the "control section" of the rack and pinion mechanism described above. In this case, the drive source rotates the pinion gear to move the drawer main body from the drawer opening to the external removal position on the side of the case, and then artificially pushes it inside the case to prevent it from being stored in the fire hydrant storage section. It is possible.

Furthermore, the structure and function of the "first plunger mechanism", which is another example of the "drive mechanism", may be arbitrary, but for example, it may be composed of a plunger drive section and a control section.

Here, the "plunger drive unit" is a unit that protrudes the drawer main body in the drawer direction and moves it from the drawer opening to the external takeout position on the side of the casing, and its structure and function are arbitrary, but for example, This is an electromagnetic solenoid (push solenoid) that energizes a fixed core by energizing a coil to project a plunger (push rod) that is a movable core.

In addition, the "control unit" is a unit that controls the plunger drive unit to be driven in the direction of protruding the drawer body to the outside by operating a switch, and its configuration and function may be arbitrary, but for example, it may be a pull-out switch. and a control circuit section. As mentioned above, the "retrieval switch" is a switch that is operated by a road user or administrator to instruct the fire extinguisher storage device to retrieve the fire extinguisher, and also refers to the "control circuit The "section" is for controlling the plunger drive section to drive the plunger drive section in the direction of protruding the drawer main body to the outside when the operation of the switch is detected.

Further, the structure and function of the "second plunger mechanism", which is another example of the "drive mechanism", may be arbitrary, but for example, it may be composed of a first plunger drive section, a second plunger drive section, and a control section. It is something that will be done.

Here, the "first plunger drive section" is a device that protrudes the drawer main body in the drawer direction and moves it from the drawer opening to the external takeout position on the side of the casing, and its structure and function are arbitrary. For example, it is an electromagnetic solenoid (push solenoid) that excites a fixed iron core by energizing a coil to project a plunger (push rod) that is a movable iron core.

Furthermore, the "second plunger drive section" is a device that releases the lock of the drawer main body before the first plunger drive section pushes the drawer main body in the drawing direction, and its structure and function are arbitrary. For example, it is an electromagnetic solenoid (pull-in solenoid) that excites a fixed iron core by energizing a coil and pulls in a plunger (push rod) that is a movable iron core.

Furthermore, the "control unit" is a unit that drives the first plunger drive unit and the second plunger drive unit, and its configuration and function may be arbitrary, but for example, it may be configured with a take-out switch and a control circuit unit. It is something that Here, the "retrieval switch" is a switch that is operated by a road user or administrator to instruct the fire hydrant device to retrieve the fire extinguisher, as described above, and the "control circuit section" is a control that drives the second plunger drive source to release the lock of the drawer body when the operation of the eject switch is detected, and also drives the second plunger drive source in the direction of protruding the drawer body to the outside. This is what we do.

Further, a "gas damper mechanism with a lock control mechanism", which is another example of the "drive mechanism", is composed of a gas damper and a control section.

Here, the term "gas damper" refers to a device that is equipped with a lock control mechanism that unlocks a piston that is slidably provided in a cylinder and moves the cylinder and piston relative to each other based on the pressure of the filled inert gas. The concept includes a gas spring.

In addition, the "control unit" is a device that unlocks the gas damper and moves the drawer body to the external drawer position by operating a switch, and its configuration and function can be arbitrary, but for example, it can be used as a take-out switch. , a storage switch, a first position detector, a second position detector, and a control circuit section.

Here, the "retrieval switch" is a switch that is operated by a road user or administrator to instruct the fire hydrant device to retrieve the fire extinguisher, and the "storage switch" is Similarly, it is used to instruct storage of the fire extinguisher, and the "first position detector" is used to detect when the drawer main body reaches the removal position, and the "second position detector" is used to detect when the drawer main body reaches the removal position. This is to detect when the vehicle reaches the storage position.

Furthermore, the "control circuit section" is a device that unlocks the gas damper and moves the drawer body to the external drawer position when the operation of the eject switch is detected, and then a detection signal is obtained from the first position detector. When the storage switch is detected, the gas damper is locked to stop the movement of the drawer body, and when the operation of the storage switch is detected, the gas damper is unlocked to allow the drawer body to move to the storage position. When a detection signal is obtained from the two-position detector, the gas damper is locked to stop the movement of the drawer body.

When the drive mechanism is a "plunger mechanism," it is desirable that the drawer mechanism supports the drawer main body so as to be movable in a drawer direction at a predetermined angle that is inclined diagonally downward with respect to the horizontal direction. The "predetermined downwardly inclined angle" is arbitrary, but is, for example, about 2 to 3 degrees. When the drawer body is pushed out by the plunger mechanism, a force is applied to move the drawer body in the inclining direction due to its own weight, making it possible to reliably move the fire extinguisher to the removal position even if the drawer body is pushed out with a light force. It is something to do.

Here, "horizontal" does not necessarily mean parallel to the level indicated by the spirit level, that is, perpendicular to the vertical, but also approximately parallel to the tunnel road surface, or at least corresponds to the installation location if the road surface has a varying slope. In addition, when the width direction of the casing is installed along such a parallel direction, it is substantially parallel to the lateral direction (left-right direction, width direction) of the casing in the installed state. This concept includes being substantially perpendicular to the longitudinal direction (vertical direction, height direction) of the casing. Moreover, a "horizontal line" is a line substantially parallel to the "horizontal" direction.

Further, the structure and function of the "feed screw mechanism" which is another example of the "drive mechanism" are arbitrary, but for example, it is composed of a screw shaft, a moving member, a drive source, and a control section.

Here, the "screw shaft" is rotatably arranged at a predetermined position of the fire extinguisher storage part along the direction in which the drawer main body is taken in and taken out, for example, at the bottom. Further, the "movable member" is a member that is arranged (fixed) at a predetermined position on the depth side of the drawer main body, for example, on the bottom back surface, and has a screw hole screwed into a screw shaft. In addition, the "drive source" is a device that moves a movable member by rotation of a screw shaft to move the drawer main body in and out of the drawer opening on the side of the case, and its structure, mechanism, and type are arbitrary, but for example, , an electrically operated motor is used. Further, the "control unit" controls the drive source to be driven in the drawing direction or the drawing direction of the drawer main body by operating a switch.

The "control section" of the feed screw mechanism is composed of a take-out switch, a storage switch, a first position detector, a second position detector, and a control circuit section, similar to the "control section" of the rack and pinion mechanism described above. When the operation of the take-out switch is detected, the drive source is driven in the direction of pulling out the drawer main body, and then, when a detection signal is obtained from the first position detector, the drive source is stopped and the storage switch is activated. When the operation is detected, the drive source is driven in the drawing direction of the drawer main body, and thereafter, when a detection signal is obtained from the second position detector, the drive source is stopped.

In addition, the extraction switch used to operate the fire extinguisher drawer mechanism includes a dedicated switch provided on the front of the casing corresponding to the fire extinguisher storage area or other locations, or a transmitter provided on the electrical door on the front of the casing. It is a switch that has a layout and structure that makes it easy for road users who use the fire extinguisher to operate it.

Moreover, in the fire extinguisher storage device of this embodiment, the fire extinguisher is vertically arranged in the fire extinguisher storage section within the housing. Here, "placing the fire extinguisher vertically" means placing the fire extinguisher in an upright position with the container facing down and the opening lever and fixing lever facing upward.

In addition, the fire extinguisher is placed vertically in the drawer body that is pulled out to the outside of the side of the case, and is exposed to the front and top. The fire extinguisher can be taken out by lifting the fire extinguisher from the bottom to the top. Lifting the fire extinguisher from the bottom to the top is an operation that allows you to exert force in a comfortable position, so it is suitable for vulnerable people such as women and the elderly. This also allows the fire extinguisher to be easily taken out and used.

In addition, in the fire extinguisher storage device of this embodiment, the fire extinguisher is placed horizontally in the fire extinguisher storage section within the housing. Here, "laying the fire extinguisher horizontally" means placing the fire extinguisher in a horizontal position, which makes it possible to reduce the storage space for the fire extinguisher in the height direction within the housing.

In addition, "horizontal placement of the fire extinguisher" means that the fire extinguisher is placed horizontally in the drawer body in two stages, upper and lower, and when pulled out to the outside of the side of the case, the fire extinguisher is exposed at least on the front side. The fire extinguisher is placed horizontally so that road users can take it out and use it by holding the fire extinguisher's fixed lever with one hand and supporting the body of the fire extinguisher with the other hand.

Moreover, the "fire extinguisher drawer structure" of the embodiment includes a "fire extinguisher moving mechanism." "Fire extinguisher moving mechanism" means that when a fire extinguisher placed vertically is moved to a pull-out position outside the side of the case using a fire extinguisher drawer structure, the fire extinguisher is maintained in a vertically placed state and the front is monitored. It is moved onto the road surface of the passenger passageway, and its structure and mechanism are arbitrary, but for example, it is equipped with a box frame and a parallel link mechanism.

Here, the "box frame" is a container that opens at least forwardly and upwardly, has a fire extinguisher placed therein vertically, and functions as a container that is mounted on the drawer main body. In addition, the "parallel link mechanism" is provided on each side of the box frame, and when the drawer main body moves to the drawer position, the box frame is monitored from the fire extinguisher storage part in the case by a predetermined operation. This is a mechanism that moves the vehicle to a predetermined position on the road surface of the passenger passageway.

Moreover, the "parallel link mechanism" is composed of a base, a first horizontal link, a second horizontal link, and a box frame. Here, the "base" is fixed to the upper part of the drawer main body. Moreover, the "first horizontal link" is a member whose lower end is pivotally supported on the rear end side of the base and whose upper end is pivotally supported on the rear end side of the upper side surface of the box frame. Moreover, the "second horizontal link" is a member whose lower end is pivotally supported on the front end side of the base and whose upper end is pivotally supported on the front end side of the upper side surface of the box frame body.

Furthermore, in the "parallel link mechanism", the position where the lower ends of the first horizontal link and the second horizontal link are pivotally supported on the base is such that the first horizontal link and the second horizontal link rotate forward with respect to the base. This is the height at which the lower part of the box frame passes without contacting the base when the box frame moves onto the road surface of the observer's passage.

Therefore, according to the fire extinguisher moving mechanism, when the fire extinguisher drawer structure moves the drawer main body to the exposed pull-out position on the side of the case, the box frame body on which the fire extinguisher is placed vertically moves from the parallel link The mechanism allows the fire extinguisher to be moved and placed on the observer's path in front of the drawer body, making it possible to take out the fire extinguisher safely and easily, and enabling quick firefighting operations using the fire extinguisher. In addition, by moving and placing the fire extinguisher on the lifeguard path, road users can not only take out the fire extinguisher from the lifeguard path, but also allow road users to safely and easily access the fire extinguisher from the road side. It becomes possible to take it out.

In addition, when the fire extinguisher drawer structure moves the drawer body to the pulled-out position, the "fire extinguisher moving mechanism" releases the fixation of forward movement of the box frame body by a predetermined operation and moves the box frame body using a parallel link mechanism. Equipped with a "fixation mechanism" that allows the body to move forward. When the drawer main body is pulled out to the outside side of the case due to the fire extinguisher drawer structure, the box frame on which the fire extinguisher mounted on the drawer main body is fixed, but the fire extinguisher drawer structure prevents the drawer from being pulled out. When the main unit moves to the exposed pull-out position on the side of the case, the fixation of the box frame is released and the box frame with the fire extinguisher placed on it is automatically moved onto the road surface of the lifeguard passage in front by the parallel link mechanism. The fire extinguisher can be retrieved by moving to the

Hereinafter, specific embodiments will be described. In the specific embodiments shown below, the "fire extinguisher storage device" is a "fire hydrant device" or a "fire extinguisher box," and the "fire hydrant device or fire extinguisher box is mounted on a mount installed on the lifeguard passage in the tunnel." A fire extinguisher drawer storage structure is provided in the fire extinguisher storage area of the housing, and a fire extinguisher door installed on the side of the housing near the fire extinguisher storage area is ``side fire extinguisher door'', and the ``drive mechanism when the fire extinguisher is placed vertically'' is a ``rack and pinion mechanism,'' ``pulley mechanism,'' ``plunger mechanism,'' ``gas damper mechanism with lock control mechanism,'' and The case where it is a "feed screw mechanism" will be explained. Next, we will explain the case where a "fire extinguisher moving mechanism" is provided in the "fire extinguisher drawer structure when the fire extinguisher is placed vertically," and then, "the fire extinguisher drawer structure when the fire extinguisher is placed horizontally." "Structure" will be explained. Furthermore, we will explain the "fire extinguisher box" installed inside the tunnel.

[b. Installation of fire hydrant equipment]
The installation of a fire hydrant device in a tunnel will be explained in more detail. As shown in FIGS. 1 and 2, a road 15 is constructed in the longitudinal direction (left and right direction) of the tunnel at the bottom of the cylindrical (circular cross-section) tunnel body constructed using the shield construction method, and a road 15 is constructed on the rear side of the road 15. An observer passage 35 having a predetermined height with respect to the road 15 is constructed below the tunnel wall surface 17 along the tunnel.

Since it is difficult to unbox the tunnel wall surface 17 using the shield construction method to install the fire hydrant device 10, a pedestal 30 is installed on the road surface of the lifeguard passageway 35 close to the tunnel wall surface 17, and the connected The fire hydrant device 10 is installed by attaching and fixing the first housing 11a and the second housing 11b onto the frame 30. Here, the height H1 of the pedestal 30 is set so that the height from the road surface of the lifeguard passageway 35 to the transmitter 24 placed on the fire hydrant device 10 falls within the legally defined range of 800 mm to 1500 mm. has been done.

Further, as shown in FIG. 2, the pedestal 30 of this embodiment has a side surface shaped like an inverted trapezoid with the top side longer than the bottom side, and the rear side is a sloped surface diagonally downward along the curved shape of the tunnel wall surface 17. . The first casing 11a and the second casing 11b, to which the fire hydrant device 10 is connected, are attached and fixed to the upper end surface of the pedestal 30. Furthermore, a water supply pipe 48 is connected to the fire hydrant device 10, which is raised from within the duct under the road surface of the lifeguard passageway 35 through the pedestal 30.

[c. Installation height and thinning of fire hydrant equipment]
The installation height and thinning of the fire hydrant device will be explained in more detail. In the description, reference is made to FIG. 3, which is an explanatory diagram schematically showing the installation state of the fire hydrant device in a tunnel cross section.

In this embodiment, in order to reduce restrictions on passage width due to the protrusion (protrusion) from the tunnel wall surface 17 of the fire hydrant device 10 installed on the road surface of the lifeguard passageway 35 by the mount 30, the fire hydrant device 10 is The installation height is optimized, and the fire hydrant device 10 is made as thin as possible.

First, since the installation height of the fire hydrant device 10 is determined by the pedestal 30, optimization of the height H1 of the pedestal 30 will be described in more detail. The tunnel wall surface 17 on which the fire hydrant device 10 is installed has a circular cross section, and in FIG. In the fire hydrant device 10 installed on the member passageway 35, the height H1 of the pedestal 30 is set so that the horizontal casing center line SL2 passing through the center in the height direction is as close as possible.

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.

FIG. 3(B) shows a case where the height H1 of the pedestal 30 is set so that the housing centerline SL2 coincides with the tunnel centerline 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 pedestal 30 will be adjusted within the possible range, taking into account the need to take out the fire extinguisher, etc.

Next, making the fire hydrant device 10 thinner will be explained in more detail. Among the devices stored in the fire hydrant device 10, the fire extinguisher stored in the second housing 11b has the largest size in the front-rear direction, and the width (thickness in the front-rear direction) of the fire hydrant device has the largest size in the front-rear direction. If the width of the fire hydrant device 10 is the minimum value that allows the fire extinguisher to be stored in the casing 11b, it is possible to make the fire hydrant device 10 thinner. is set to the width of

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, in the range of about 180 to 200 mm. The width of the fire hydrant device 10 is set to a predetermined width within the range. On the other hand, since the width of the conventional fire hydrant device 10, which is installed by punching out a box in the wall of a tunnel frame and embedding it, is about 300 mm, the width of the fire hydrant device 10 of this embodiment is set to 2/3 or less of the conventional width. Therefore, the fire hydrant device 10 can be made thinner.

[d. Configuration compatible with thinner fire hydrant equipment]
When the fire hydrant device 10 is thinned to a predetermined width in the range of about 180 to 200 mm in accordance with the outer diameter of the fire extinguisher, the first housing 11a is equipped with a fire hose of a predetermined length as in the conventional fire hydrant device, For example, it becomes difficult to store a 30 m long shape-retaining hose in an inwardly wound state. Therefore, in this embodiment, by increasing the width (width in the left-right direction) of the first housing 11a, a shape-retaining hose of the same predetermined length as the conventional hose can be stored in an inwardly wound state.

Additionally, as the fire hydrant device 10 becomes thinner, it becomes difficult to arrange the terminal boxes 26a and 26b on the rear surface of the casing on the rear side of the fire extinguisher storage section where the fire extinguisher is stored, as in conventional fire hydrant devices. . Therefore, in the present embodiment, the width (length in the left-right direction) of the second housing 11b is increased to accommodate a fire extinguisher and to allow placement of electrical equipment and a terminal box.

[e. Structure of fire hydrant device]
The structure of the fire hydrant device will be explained in more detail.

The motor 80 moves the rack bar 76 in the drawing direction by the rotation of the pinion gear 78 by normal rotation, and accordingly moves the drawer main body 32 in the drawing direction. Further, the motor 80 moves the rack bar 76 in the retracting direction by rotating the pinion gear 78 by reverse rotation, and accordingly moves the drawer main body 32 in the retracting direction. Furthermore, the motor 80 of this embodiment is equipped with a speed reduction mechanism and is, for example, a DC motor that outputs rotation at low speed and high torque, and the direction of rotation can be switched by switching the polarity of the applied voltage. .

The first position detector 82 detects when the drawer main body 32 reaches the fire extinguisher removal position, and its structure, function, and type are arbitrary, but for example, a limit switch is used, as shown in FIG. 11. The switch structure is such that the positioning member 86, which is disposed inside the bottom of the drawer opening 34 and protrudes downward from the back side of the drawer main body 32, comes into contact with the switch lever to switch from on to off. . Here, as shown in FIG. 13(C), the first position detector 82 is arranged at a position offset to one side with respect to the center line of the bottom of the casing in the pull-out direction. The same applies to the second position detector 84 in this respect. Further, as shown in FIG. 12(D), the positioning member 86 is located at a position offset to the same side as the first position detector 82 and the second position detector 84 with respect to the center line of the housing body 32 in the drawing direction. It is placed so as to protrude downward.

The second position detector 84 detects when the drawer main body 32 reaches the storage position, and its structure, function, and type are arbitrary, but for example, a limit switch is used, and as shown in FIG. , when the positioning member 86, which is disposed at a predetermined position on the bottom of the rear end side of the housing guide rail 42 and protrudes downward from the back side of the drawer main body 32 as shown in FIG. 10, comes into contact with the switch lever. , it has a switch structure that changes from on to off.

(f6. Rack and pinion mechanism control section)
The control section of the rack and pinion mechanism will be explained in more detail. In this description, reference is made to FIG. 15, which shows the control section of the rack and pinion mechanism. Note that FIG. 15(A) shows a control section using a computer circuit, and FIG. 15(B) shows a control section using a relay circuit.

The control unit of the rack and pinion mechanism controls the motor 80 to move the drawer main body 32 in the pull-out direction or in the pull-in direction in accordance with the operation of the switch, and its configuration and function are arbitrary, but for example, as shown in FIG. 15(A) As shown in FIG. 2, it is composed of a takeout switch 27, a storage switch 29, a first position detector 82, a second position detector 84, and a control circuit section 85.

A take-out switch 27 , a storage switch 29 , a first position detector 82 , and a second position detector 84 are input connected to the control circuit section 85 , and a control signal (drive voltage) from the control circuit section 85 is applied to the motor 80 . The motor 80 is connected to the pinion gear 78 of the rack and pinion mechanism 88 .

Although the configuration and functions of the control circuit unit 85 are arbitrary, for example, it is a computer circuit equipped with a CPU, memory, and various input/output ports, and the control function is obtained by executing a program by the CPU. Note that the control circuit section 85 is not limited to a computer circuit, but includes appropriate electric circuits and electronic circuits such as sequence circuits and logic circuits.

When the control circuit unit 85 detects the operation of the extraction switch 27, the control circuit unit 85 rotates the motor 80 in the forward direction, drives the rack bar 76 in the extraction direction by rotation of the pinion gear 78 of the rack and pinion mechanism 88, and moves the extraction main body 32 into the housing. Move it to the external extraction position on the side of the body. When the drawer main body 32 moves to the take-out position, a detection signal is obtained from the first position detector 82, and the control circuit section 85 stops driving the motor 80 to stop the drawer main body 32 at the take-out position outside the side surface of the casing. .

On the other hand, after using the fire extinguisher, if a new fire extinguisher is to be placed vertically on the drawer main body 32 and returned to the fire extinguisher storage section, the storage switch 29 is operated. When the control circuit unit 85 detects the operation of the storage switch 29, the control circuit unit 85 rotates the motor 80 in the reverse direction, drives the rack bar 76 in the retracting direction by rotation of the pinion gear 78 of the rack and pinion mechanism 88, and extinguishes the drawer main body 32. Move it to the container storage area. When the drawer main body 32 moves to the storage position, a detection signal is obtained from the second position detector 84, and the control circuit section 85 stops driving the motor 80 to stop the drawer main body 32 in the storage position of the fire hydrant storage section.

In addition, the relay circuit functioning as a control section of the rack and pinion mechanism shown in FIG. It consists of a functional limit switch LS2, a relay X with relay contacts X1, X2, and X3, and a relay Y with relay contacts Y1, Y2, and Y3.

In the relay circuit, when the take-out switch 72 is turned on, the relay The rack and pinion mechanism is driven to move the drawer main body 32 in the drawing direction. When the drawer main body 32 moves to the external take-out position on the side of the case, the limit switch LS1 opens, the relay Stop at the external take-out position.

On the other hand, after using the fire extinguisher, when placing a new fire extinguisher vertically in the drawer body 32 and returning it to the fire extinguisher storage section, when the storage switch 29 is turned on, the relay circuit operates, relay contact Y1 closes and self-holds, and relay contacts Y2 and Y3 close to apply a DC voltage of opposite polarity to the motor 80 to rotate it in the reverse direction, driving the rack and pinion mechanism to rotate the drawer main body 32. move in the retraction direction. When the drawer main body 32 moves to the storage position in the housing, the limit switch LS2 opens, the relay Y is restored and the relay contacts Y1 to Y3 open, the drive of the motor 80 is stopped, and the drawer main body 32 is moved to the storage position in the fire hydrant storage section. to stop.

[g. Fire extinguisher drawer structure with pulley mechanism]
The fire extinguisher drawer structure equipped with a pulley mechanism will be explained in more detail. In this explanation, the fire extinguisher drawer structure equipped with a pulley mechanism is shown in FIG. Please refer to FIG. 17, which shows a partial cross section when viewed from the front, and FIG. 18, which shows a control section of the pulley mechanism.

(g1. Pulley mechanism)
The pulley mechanism moves the drawer main body 32 from the drawer opening 34 to the external take-out position on the side of the casing by operating a predetermined switch, and its structure and function can be arbitrary. It is composed of a pulley 92, a string member 94, a position detector 96, a positioning member 98, and a control section (not shown).

The folding pulley 90 is rotatably arranged at a predetermined position on the bottom near the drawer opening 34 of the fire hydrant storage section 50c, and is wound around a string member 94 whose one end is fixed to the rear end (deep end) of the drawer main body 32. It is folded back toward the rear end.

As shown in FIG. 17, the winding pulley 92 is fixed to the output shaft of a motor placed at a predetermined position at the rear bottom of the housing guide rail 42, and is rotated in the direction of winding the string member 94 by the forward rotation of the motor. Drive.

The position detector 96 detects when the drawer main body 32 reaches the external fire extinguisher extraction position on the side of the case, and its structure, function, and type are arbitrary, but for example, a limit switch is used. . A positioning member 98 for operating a position detector 96 is provided at the rear end (depth end) of the drawer main body 32 and protrudes downward from the back surface.

Normally, as shown in FIG. 16, the drawer main body 32 of the fire extinguisher drawer structure is pushed into the position where the side fire extinguisher door 16 closes the drawer opening on the side of the casing, and is stored in the storage position of the fire hydrant storage section 50c. has been done.

When using the fire extinguisher 72, the take-up pulley 92 is rotated by the motor driven by the operation of the take-out switch 27, and the string member 94, one end of which is fixed to the rear part of the drawer main body 32, is connected via the folding pulley 90. Winding is started, and the drawer main body 32 moves in the drawing direction by being pulled by the string member 94. As shown in FIG. 17, when the positioning member 98 protruding from the bottom back surface of the drawer main body 32 moves to a position where it comes into contact with the switch lever of the position detector 96, a detection signal is output from the position detector 96, and the motor starts winding. When the rotation of the take-up pulley 92 stops, the drawer main body 32 is pulled out to the take-out position outside the draw-out opening 34 and stops, allowing the fire extinguisher 72 to be taken out.

After using the fire extinguisher, when placing a new fire extinguisher vertically in the drawer main body 32 and returning it to the fire extinguisher storage section 50c, the administrator moves the side fire extinguisher door 16 to a position where the drawer opening 34 is closed. Push it back in by hand. In this case, since no drive voltage is applied to the motor 92, the motor 92 can rotate by receiving the force associated with pushing the drawer main body 32 through the string member 94. Therefore, as the drawer main body 32 is pushed in, the string member 94 is unwound from the take-up pulley 92, and the side fire extinguisher door 16 can be moved to the storage position where the drawer opening 34 is closed.

(g2. Pulley mechanism control unit)
Next, the control section of the pulley mechanism will be explained in more detail. The control unit of the pulley mechanism controls the movement of the drawer main body 32 in the direction of pulling it out to the outside by operating a switch, and its configuration and function can be arbitrary, but for example, as shown in FIG. 18(A), , a take-out switch 27, a position detector 96, and a control circuit section 100.

A take-out switch 27 and a position detector 96 are input connected to the control circuit section 100 , and a control signal (drive voltage) from the control circuit section 100 is output to a motor 102 . A pulley 92 is connected to the output shaft.

Although the configuration and functions of the control circuit section 100 are arbitrary, for example, it is a computer circuit equipped with a CPU, memory, and various input/output ports, and the control function is obtained by executing a program by the CPU. Note that the control circuit section 100 is not limited to a computer circuit, but includes appropriate electric circuits and electronic circuits such as sequence circuits and logic circuits.

When the control circuit section 100 detects the operation of the take-out switch 27, the control circuit section 100 rotates the motor 102 in the forward direction, and winds up the string member 94 via the folding pulley 90 by the rotation of the winding pulley 92 of the pulley mechanism 104. The drawer main body 32 is moved in the direction of drawing it out. When the drawer main body 32 moves to the take-out position, a detection signal is obtained from the position detector 96, and the control circuit section 100 stops driving the motor 102 to stop the drawer main body 32 at the take-out position outside the side surface of the casing.

Moreover, the control section of the pulley mechanism may be a relay circuit shown in FIG. 18(B) as another embodiment. A relay circuit that functions as a control section of the pulley mechanism includes a take-out switch 27, a limit switch LS that functions as a position detector 96, and a relay X that includes relay contacts X1 and X2.

In the relay circuit, when the take-out switch 72 is turned on, the relay X is activated, closes the relay contact X1 and maintains itself, and also closes the relay contact X2 to apply DC voltage to the motor 102 and rotate it, causing the pulley The winding pulley 92 of the mechanism is driven to rotate, the string member 94 is wound up, and the drawer main body 32 is moved in the drawing direction. When the drawer main body 32 moves to the take-out position, the limit switch LS opens, the relay X is restored, the relay contacts X1 and X2 open, the drive of the motor 102 is stopped, and the drawer main body 32 is moved to the take-out position outside the side of the casing. make it stop.

[h. Fire extinguisher drawer structure with first plunger mechanism]
The fire extinguisher drawer structure equipped with the first plunger mechanism will be described in more detail. In this explanation, the fire extinguisher drawer structure equipped with a plunger mechanism is shown in FIG. Please refer to FIG. 20, which shows a partial cross section when viewed from the front.

(h1. First plunger mechanism)
The first plunger mechanism, which functions as a drive mechanism of the fire extinguisher drawer structure, pushes out and drives the drawer body 32 in the direction of pulling out the drawer body 32 to the outside by operating the takeout switch 27, and its structure and function are arbitrary. As shown in FIGS. 19 and 20, it is composed of a plunger drive section 106, a plunger 108, and a control section (not shown).

The plunger drive unit 106 is disposed at a predetermined position on the bottom surface of the drawer main body 32 housed in the fire hydrant storage section 50c, which is the rear end side (depth end part), and is driven to protrude and retract relative to the rear end of the drawer main body 32. A plunger 108 is provided. The structure and function of the plunger drive unit 106 are arbitrary, but for example, in the case of an electromagnetic solenoid, the fixed iron core is excited by energizing the coil, and the plunger 108, which is the movable iron core, is attracted and the drawer main body 32 is moved in the drawing direction. It has a protruding configuration. Note that when the electromagnetic solenoid is de-energized, the plunger 108 returns to its initial position by the force of a spring.

The control unit of the first plunger mechanism is an arbitrary electric circuit, and for example, operates the extraction switch 27 to energize the electromagnetic solenoid of the plunger drive unit 106, and also controls the movement of the drawer main body 32 from the storage position. The electric circuit is configured to stop the energization of the electromagnetic solenoid when a detection signal from the position detector is obtained.

Normally, as shown in FIG. 19, the drawer main body 32 of the fire extinguisher drawer structure is pushed into the position where the side fire extinguisher door 16 closes the drawer opening on the side of the casing, and is stored in the storage position of the fire hydrant storage section 50c. has been done.

When using the fire extinguisher 72, when the take-out switch 27 is operated, the electromagnetic solenoid of the plunger drive unit 106 is energized to drive the plunger 108 and push out the drawer body 32 in the drawing direction. The drawer main body 32 is pushed out to the removal position outside the drawer opening 34, and the fire extinguisher 72 can be removed. After using the fire extinguisher, when placing a new fire extinguisher vertically in the drawer main body 32 and returning it to the fire extinguisher storage section 50c, the administrator moves the side fire extinguisher door 16 to a position where the drawer opening 34 is closed. Push it back in by hand.

(h2. Inclined structure of drawer mechanism)
The inclined structure of the pull-out mechanism in the fire extinguisher pull-out structure including the first plunger mechanism will be described in more detail. In the description, reference is made to FIG. 21, which shows a fire extinguisher drawer structure including a plunger mechanism having a downward inclination angle in the drawer direction.

As shown in FIG. 21, in the drawer mechanism of the fire extinguisher drawer structure equipped with the first plunger mechanism of this embodiment, a drawer main body 32 is provided on the bottom side of the side fire extinguisher door 16 located in the vertical direction. Although one end is fixed in the vertical direction (right angle), the longitudinal center line SL2 of the main body guide rail 36 provided on the drawer main body 32 is inclined diagonally downward in the drawer direction (to the left) with respect to the horizontal line HL. It is set at a predetermined angle θ. Furthermore, the center line SL3 of the housing guardrail 42 fixed to the bottom corner of the fire extinguisher storage section 50c of the second housing 11b is inclined diagonally downward in the pull-out direction (left direction) with respect to the horizontal line HL at the same predetermined angle θ. is set to . Here, the downward inclination angle θ is arbitrary, but is, for example, about 2 to 3 degrees.

Therefore, by slidably inserting the main body guide rail 36 into the housing guide rail 42, the drawer main body 32 is stored in the fire extinguisher storage part 50c in a state tilted diagonally downward in the direction of the drawer, and the extinguisher is extinguished. The drawer main body 32 on which the container 72 is placed vertically is subjected to a sliding force in the direction of inclination due to its own weight. Therefore, when the plunger 108 pushes out the drawer main body 32 by driving the plunger drive unit 106, a synergistic effect is obtained with the force of moving the drawer main body 32 in the inclination direction due to its own weight on which the fire extinguisher 72 is placed, and the drawer main body 32 is pushed out. The main body 32 reliably moves to the fire extinguisher removal position. Further, the force for pushing out the plunger 108 by the plunger drive unit 106 can be made smaller than in the case where there is no inclination angle θ, so the plunger mechanism can be made smaller.

[i. Fire extinguisher drawer structure with second plunger mechanism]
The fire extinguisher drawer structure equipped with the second plunger mechanism will be described in more detail. In the description, reference will be made to FIG. 19, which shows a partially cross-sectional view of a fire extinguisher drawer structure equipped with a second plunger mechanism when viewed from the front in a fire extinguisher storage state.

The second plunger mechanism, which functions as a drive mechanism of the fire extinguisher drawer structure, is driven to project the drawer body 32 in the direction of pulling it out to the outside by operating the take-out switch 27, and its structure and function are arbitrary. As shown in FIG. 22, it is comprised of a plunger drive section 106 that functions as a first plunger drive section and an unlocking plunger drive section 107 that functions as a second plunger drive section.

The plunger drive unit 106 is similar to the first plunger drive mechanism shown in FIG. 19, and is located at a predetermined position on the bottom surface of the drawer main body 32 stored in the fire hydrant storage unit 50c at the rear end side (depth end). A plunger 108 is disposed at the rear end of the drawer main body 32 and protrudes when energized. Note that when the electromagnetic solenoid is de-energized, the plunger 108 returns to its initial position by the force of a spring.

The unlocking plunger drive unit 107 is disposed at a predetermined position on the bottom surface of the drawer main body 32 stored in the fire hydrant housing 50c, which is the rear end side (depth end), for example, at a position in front of the plunger drive unit 106. It is provided with a plunger 109 that faces the bottom of the drawer main body 32 and is drawn in when energized. Note that when the electromagnetic solenoid is de-energized, the plunger 109 is projected to the locking position by the force of the spring.

The control unit of the second plunger mechanism is an arbitrary electric circuit, for example, an electric circuit that sequentially energizes the electromagnetic solenoids of the unlocking plunger drive unit 107 and the plunger drive unit 106 by operating the ejection switch 27. do.

Normally, as shown in FIG. 22, the drawer main body 32 of the fire extinguisher drawer structure is pushed into the position where the side fire extinguisher door 16 closes the drawer opening on the side of the casing, and is stored in the storage position of the fire hydrant storage section 50c. The plunger 109 of the unlocking plunger drive unit 107 is locked to the bottom of the drawer main body 32, thereby locking the movement of the drawer main body 32.

When using the fire extinguisher 72, when the take-out switch 27 is operated, the electromagnetic solenoid of the unlocking plunger drive unit 107 is first energized, and the drawer body 32 is unlocked by retracting the plunger 109. . Subsequently, the electromagnetic solenoid of the plunger drive unit 106 is energized to drive the plunger 108 and project the drawer main body 32 in the drawing direction. Therefore, the drawer main body 32 is pushed out to the extraction position outside the drawer opening 34 by the movement of the main body guide rail 36 along the case guide rail 42 (see FIG. 21) arranged diagonally downward, and the fire extinguisher 72 can be taken out. After using the fire extinguisher, if a new fire extinguisher is to be placed vertically on the drawer main body 32 and returned to the fire extinguisher storage section 50c, the administrator closes the side fire extinguisher door 16 and the drawer opening 34. Push it back into position by hand.

[j. Drive mechanism with gasle damper with lock control function]
The structure drive mechanism provided with a gas damper with a lock control function will be described in more detail. For this explanation, please refer to FIG. 23 showing a drive mechanism provided with a gas damper with a lock control mechanism, FIG. 24 showing details of the gas damper, and FIG. 25 showing a control section of the drive mechanism in FIG. 22. do. Note that FIG. 24(A) shows an exploded view of the gas damper, and FIG. 24(B) shows a sectional view of the internal structure of the gas damper.

(j1. Drive mechanism equipped with gas damper)
Drive mechanism provided with a gas damper The drive mechanism moves the drawer main body 32 from the drawer opening 34 to the external extraction position on the side of the casing by operating a predetermined switch, and its structure and function are arbitrary, but for example, , a gas damper 120, a lock control mechanism 150, a plunger drive section 160, and a control section (not shown).

The gas damper 120 includes a cylinder 1210 and a rod 1212, and the left end of the cylinder 1210 is pivoted on the bottom surface of the drawer main body 32 near the end on the drawer side by a cylinder connecting portion 130 so as to be rotatable and slightly movable up and down. However, the tip of the rod 1212 taken out from the cylinder 1210 to the right is attached and fixed to a rod fixing part 140 arranged at the bottom of the fire extinguisher storage part 50c.

As shown in the exploded view of FIG. 24(A), a push pin 1211 protrudes from the tip of a rod 1212 taken out from the cylinder 1210 of the gas damper 120. When the push pin 1211 is pushed in, the lock of the gas damper 120 is released, and when the rod 1212 is set to the fixed side, the cylinder 1210, which is the moving side, can be moved to the left, which is the drawing direction.

The lock control mechanism 150 is a mechanism that pushes the push pin 1211 of the gas damper 120, and the release head 1214. It is composed of a release wire 1218 and a push button unit 1216 including a push button 1215. The release head 1214 can be attached to a threaded portion 1213 at the tip of the rod, and a release wire 1218 is drawn out from the release head 1214 and connected to the push button unit 1216 by wire. The push button unit 1216 is provided with a push button 1215 pushed out by a spring. Further, the nut 1220 is screwed into the threaded portion 1213 to attach and fix the tip of the rod 1212 to the rod fixing portion 140 disposed at the bottom of the fire extinguisher storage portion 50c, as shown in FIG.

As shown in FIG. 23, the push button unit 1216 is disposed on the bottom of the fire extinguisher storage section 50c following the rod fixing section 140, and is driven by a plunger drive section 160 disposed on the bottom opposite the push button 1215. The tip of plunger 162 is in contact with it.

When the plunger 162 is protruded by energizing the electromagnetic solenoid of the plunger drive unit 160 and the push button 1215 is pushed in, a known wire link mechanism connecting the push button unit 1216, the release wire 1218, and the release head 1214 moves, causing the gas damper to move. The push pin 1211 of 120 is pushed in, and while the push pin 1211 is pushed in, the gas damper 120 is unlocked.

(j2. Gas damper)
The gas damper 120 with a lock control function has a structure shown in FIG. 24(B). The gas damper 120 includes a cylinder 1210, in which a piston 1222 functioning as a first piston is slidably provided, and a separate piston 1226 functioning as a second piston following the piston 1222 is slidably provided in the cylinder. The piston 1222 is provided integrally with the rod 1212, and the rod 1212 is taken out from one end of the cylinder 1210.

Inside the cylinder 1210, a first cylinder chamber 1228, a second cylinder chamber 1230, and a third cylinder chamber 1232 are sequentially formed by the arrangement of the piston 1222 and the release piston 1226. The first cylinder chamber 1228 and the second cylinder chamber 1230 are filled with oil, and the third cylinder chamber 1232 is filled with an inert gas, such as nitrogen gas, pressurized to a predetermined pressure.

The piston 1222 is provided with an orifice 1234 and a valve 1236. A push pin 1211 is provided inside the rod 1212 so as to be movable in the axial direction, one end of which protrudes to the outside of the rod 1212, and the other end of which is connected to the valve 1236, with the illustrated push pin 1211 protruding to the outside. When the valve 1236 is closed and the push pin 1211 is pushed in, the valve 1236 is opened.

The valve 1236 opens and closes a flow path of an orifice 1234 that communicates a first cylinder chamber 1228 and a second cylinder chamber 1230 provided in the piston 1222. That is, in the push release position where the push pin 1211 protrudes to the outside, the valve 1236 closes the flow path passing through the orifice 1234 and locks the piston 1222.

In addition, at the push-in position of the push pin 1211, the valve 1236 opens the flow path passing through the orifice 1236 to unlock the piston 1222, and the cylinder 1210, which is on the movable side, is moved in the pulling direction (leftward direction) with respect to the rod 1212, which is on the fixed side. ). In this case, the moving speed corresponds to the flow resistance of the oil flowing through the orifice 1234, and the cylinder 1210 is moved slowly.

Here, when comparing the pressure receiving area S1 at the right end of the cylinder 1210 in the first cylinder chamber 1228 and the pressure receiving area S2 at the left end of the cylinder 1210 in the third cylinder chamber 1232, it is found that the pressure receiving area S1 at the left end of the cylinder 1210 in the first cylinder chamber 1228 is The pressure receiving area S1 at the right end is smaller than the pressure receiving area S2 at the right end. Further, the pressures in the first cylinder chamber 1228, the second cylinder chamber 1230, and the third cylinder chamber 1230 are equal to the pressure P of the nitrogen gas filled in the third cylinder chamber 1232.

Therefore, when the rod 1212 is on the fixed side, a rightward force F1 determined by the pressure receiving area S1 and pressure P at the right end is applied to the cylinder 1210, and a leftward force F2 determined by the pressure receiving area S2 and pressure P at the left end is applied to the cylinder 1210. Since F1<F2 holds, a leftward force (force in the pull-out direction) of (F2-F1) is applied to the cylinder 1210.

In this state, when the push pin 1211 is pressed to open the valve 1236 and unlock the piston 1222, the cylinder 1210, which is on the movable side with respect to the rod 1212, which is on the fixed side, receives a force of (F2-F1). Move to the left, which is the pull-out direction.

(j3. Control unit)
Next, the control section of the drive mechanism provided with the gas damper shown in FIG. 23 will be described in more detail. In this description, reference is made to FIG. 25, which shows a control section of a drive mechanism provided with a gas damper. Note that FIG. 25(A) shows a control section using a computer circuit, and FIG. 25(B) shows a control section using a relay circuit.

The control unit of the drive mechanism provided with the gas damper controls the movement of the drawer main body 32 in the drawer direction by unlocking the gas damper 120 in response to the operation of a switch, and its configuration and function may be arbitrary. For example, as shown in FIG. 25(A), it is composed of a takeout switch 27, a storage switch 29, a first position detector 82, a second position detector 84, and a control circuit section 85.

A take-out switch 27, a storage switch 29, a first position detector 82, and a second position detector 84 are input connected to the control circuit section 85, and the control signal (drive voltage) of the control circuit section 85 drives the plunger. It is output to section 160. Here, the take-out switch 27, the storage switch 29, the first position detector 82, and the second position detector 84 are the same as the control section of the rack and pinion mechanism shown in FIG. 15, so a description thereof will be omitted. The control circuit section 85 that controls the plunger drive section 160 has a unique configuration and function.

Although the configuration and functions of the control circuit unit 85 are arbitrary, for example, it is a computer circuit equipped with a CPU, memory, and various input/output ports, and the control function is obtained by executing a program by the CPU. Note that the control circuit section 85 is not limited to a computer circuit, but includes appropriate electric circuits and electronic circuits such as sequence circuits and logic circuits.

When the control circuit section 85 detects the operation of the ejection switch 27, it energizes the electromagnetic solenoid of the plunger drive section 160, causes the plunger 162 shown in FIG. The push pin 1211 of the gas damper 120 is pushed in to release the lock, and the fixed rod 1212 is moved in the drawing direction by the pressure of the nitrogen gas filling the cylinder 1210, and the drawer main body 32 is removed from the casing. Move it to the external extraction position on the side of the body. When the drawer main body 32 moves to the extraction position, a detection signal is obtained from the first position detector 82, and the control circuit section 85 stops energizing the plunger drive section 160, returns the plunger 162 to its original position, and presses the push button 1215. is released, the gas damper 120 is locked, and the movement of the cylinder 1210 is stopped.

On the other hand, after using the fire extinguisher, if a new fire extinguisher is to be placed vertically on the drawer main body 32 and returned to the fire extinguisher storage section, the storage switch 29 is operated. When the control circuit section 85 detects the operation of the storage switch 29, the control circuit section 85 energizes the electromagnetic solenoid of the plunger drive section 160, causes the plunger 162 shown in FIG. The push pin 1211 of the oil damper device 120 is pushed in to release the lock. When the road drawer manager pushes the drawer main body 32 into the fire extinguisher storage section 32 in this state, since the gas damper 120 is unlocked, the drawer main body 32 cannot be moved into the fire extinguisher storage section 50c. can.

When the drawer main body 32 moves to the storage position in response to the push, a detection signal is obtained from the second position detector 84, and the control circuit section 85 stops energizing the plunger drive section 160 and returns the plunger 162 to its original position. The push button 1215 is released, the gas damper 120 is locked, and the movement of the cylinder 1210 is stopped.

In addition, the relay circuit functioning as a control section of the drive mechanism provided with the gas damper shown in FIG. It is composed of a limit switch LS2 functioning as a detector 84, a relay X having relay contacts X1 and X2, and a relay Y having relay contacts Y1 and Y2.

In the relay circuit, when the take-out switch 72 is turned on, the relay X is activated, and the relay contact X1 is closed and self-maintained, and the relay contact X2 is closed and the plunger drive unit 160 is energized, so that the gas damper 120 is activated. The lock is released and the drawer main body 32 is moved in the drawing direction. When the drawer main body 32 moves to the external take-out position on the side of the casing, the limit switch LS1 opens, the relay It is locked and the drawer main body 32 is stopped at the external extraction position on the side surface of the casing.

On the other hand, after using the fire extinguisher, when placing a new fire extinguisher vertically in the drawer body 32 and returning it to the fire extinguisher storage section, when the storage switch 29 is turned on, the relay circuit operates, relay contact Y1 closes and self-holds, and relay contact Y2 closes and energizes the plunger drive unit 160 to unlock the gas damper 120, and the drawer main body 32 is pushed into the storage position. allows for movement of When the drawer main body 32 moves to the storage position in the housing, the limit switch LS2 opens, the relay Y is restored, the relay contacts Y1 and Y2 open, the plunger drive unit 160 is de-energized, and the gas damper 120 is locked. The drawer main body 32 is stopped at an external extraction position on the side surface of the casing.

[k. Fire extinguisher drawer structure with feed screw mechanism]
The fire extinguisher drawer structure equipped with a feed screw mechanism will be explained in more detail. In this explanation, the fire extinguisher drawer structure equipped with a feed screw mechanism is shown in FIG. Please refer to FIG. 27, which shows a partial cross section when viewed from the front.

(k1. Feed screw mechanism)
The feed screw mechanism that functions as a drive mechanism of the fire extinguisher drawer structure moves the drawer body 32 in the pull-out direction when the take-out switch 27 is operated, and moves the drawer body 32 in the pull-in direction when the storage switch 29 is operated. Although the structure and function are arbitrary, as shown in FIGS. 26 and 27, a screw shaft 110, a motor 112, a moving member 114, a bearing member 116, a first position detector 82, a second position detector 84, and a control section (not shown).

The screw shaft 110 is a shaft member having external threads cut at a predetermined pitch, and is rotatably arranged along the pull-out direction (left-right direction) at a predetermined position below the drawer main body 32 stored in the fire extinguisher storage section 50c. One shaft end side in the pull-in direction (depth direction) is connected to the output shaft of the motor 112 fixed to the bottom of the fire extinguisher storage section 50c, and the other shaft end side in the pull-out direction (lateral side external direction) is connected to the drawer opening. It is rotatably supported by a bearing member 116 fixed to the bottom of the fire extinguisher storage section 50c near 34.

The movable member 114 is fixed to a predetermined position on the back surface near the rear end (depth end) of the drawer main body 32 so as to protrude downward, and has a screw hole into which the screw shaft 110 is screwed. Therefore, the screw shaft 110 whose one end is connected to the output shaft of the motor 112 passes through (screws into) the screw hole of the movable member 114 fixed to the bottom surface of the drawer main body 32, and the tip thereof is connected to the shaft of the bearing member 116. Rotatably supported in the hole.

When the screw shaft 110 is rotated in the forward direction by the motor 112, the moving member 114 moves in the drawing direction, and the drawer main body 32 moves accordingly to the removal position. Further, when the screw shaft 110 is reversely rotated by the motor 112, the moving member 114 moves in the retraction direction (storage direction), and the drawer main body 32 moves accordingly to the storage position.

More specifically, when the screw shaft 110 has a right-hand thread, when the screw shaft 110 rotates to the left (corresponding to forward rotation) when viewed from the motor 112, the movable member 114 moves in the drawing direction, and the drawer main body 32 is removed accordingly. position, and on the other hand, when the screw shaft rotates clockwise (corresponding to reverse rotation), the moving member 114 moves in the retraction direction (storage direction), and the drawer main body 32 moves accordingly to the storage position.

Further, the motor 112 is equipped with a speed reduction mechanism, and is, for example, a DC motor that outputs rotation at low speed and high torque, and the direction of rotation can be switched by switching the polarity of the applied voltage.

The first position detector 82 detects when the drawer main body 32 reaches the fire extinguisher removal position, and its structure, function, and type are arbitrary, but a limit switch is used, for example, as shown in FIG. In addition, the switch structure is such that it is fixed to the depth side of a bearing member 116 disposed at the bottom near the drawer opening 34, and is switched from on to off when the moving member 114 comes into contact with the switch lever.

The second position detector 84 detects when the drawer main body 32 reaches the storage position, and its structure, function, and type are arbitrary, but for example, a limit switch is used, and as shown in FIG. , is arranged at a predetermined position on the bottom surface of the rear end side of the main body guide rail 36, and has a switch structure that is switched from on to off when the moving member 114 arranged on the back surface of the drawer main body 32 comes into contact with the switch lever. .

(k2. Control unit of feed screw mechanism)
The control section of the feed screw mechanism will be explained in more detail. The control unit of the feed screw mechanism controls the motor 112 to move the drawer main body 32 in the pull-out direction or in the pull-in direction by operating a switch, and its configuration and function are arbitrary. ), it is composed of a take-out switch 27, a storage switch 29, a first position detector 82, a second position detector 84, and a control circuit part 85. The difference is that the feed screw mechanism is controlled by the Therefore, if the motor 80 in FIGS. 15(A) and 15(B) is assumed to be the motor 112, and the rack and pinion mechanism 88 is assumed to be a feed screw mechanism, the explanation will be as follows.

In FIG. 15(A), the take-out switch 27, the storage switch 29, the first position detector 82, and the second position detector 84 are input connected to the control circuit section 85, and the control circuit section 85 receives the control signal ( A driving voltage) is output to a motor 112, and the motor 112 is connected to a screw shaft 110 of a feed screw mechanism.

When the control circuit section 85 detects the operation of the extraction switch 27, the control circuit section 85 rotates the motor 112 in the forward direction, drives the moving member 114 in the withdrawal direction by forward rotation of the screw shaft 110, and moves the drawer main body 32 to the outside of the side surface of the housing. Move it to the extraction position. When the drawer main body 32 moves to the take-out position, a detection signal is obtained from the first position detector 82, and the control circuit section 85 stops driving the motor 112 to stop the drawer main body 32 at the take-out position outside the side surface of the casing. .

On the other hand, after using the fire extinguisher, if a new fire extinguisher is to be placed vertically on the drawer main body 32 and returned to the fire extinguisher storage section, the storage switch 29 is operated. When the control circuit section 85 detects the operation of the storage switch 29, it reversely rotates the motor 112, drives the moving member 114 in the retracting direction by reversely rotating the screw shaft 110, and moves the drawer main body 32 to the fire extinguisher storage section. let When the drawer main body 32 moves to the storage position, a detection signal is obtained from the second position detector 84, and the control circuit section 85 stops driving the motor 112 to stop the drawer main body 32 at the storage position of the fire hydrant storage section.

In addition, as another embodiment of the control section of the feed screw mechanism, in the case of the relay circuit shown in FIG. It is composed of a limit switch LS2 functioning as a two-position detector 84, a relay X having relay contacts X1, X2, and X3, and a relay Y having relay contacts Y1, Y2, and Y3.

In the relay circuit, when the take-out switch 72 is turned on, the relay X is activated, closes the relay contact X1 and maintains itself, and also closes the relay contacts X2 and X3 to apply a positive DC voltage to the motor 112. Then, the screw shaft 110 is rotated in the forward direction, and the moving member 114 is moved in the drawing direction. When the drawer body 32 moves to the take-out position, the limit switch LS1 opens, the relay make it stop.

On the other hand, after using the fire extinguisher, when placing a new fire extinguisher vertically in the drawer body 32 and returning it to the fire extinguisher storage section, when the storage switch 29 is turned on, the relay circuit operates, relay contact Y1 closes and self-holds, and relay contacts Y2 and Y3 close to apply a DC voltage of opposite polarity to the motor 112 to reversely rotate the screw shaft 110 and move the movable member 114 in the retracting direction. move it to When the drawer main body 32 moves to the storage position in the housing, the limit switch LS2 opens, the relay Y is restored, the relay contacts Y1 to Y3 open, the drive of the motor 112 is stopped, and the drawer main body 32 is moved to the storage position in the fire hydrant storage section. to stop.

[l. Overview of fire extinguisher moving mechanism]
An overview of the fire extinguisher moving mechanism provided in the fire extinguisher storage section of a fire hydrant device will be described by taking as an example the case where it is applied to a fire extinguisher drawer structure having a rack and pinion mechanism in the drive part shown in FIGS. 8 to 14. In this explanation, Figure 28 shows the internal structure of the fire hydrant device before the fire extinguisher is pulled out, partially shown in cross section from the front, and Figure 28 shows the internal structure of the fire hydrant device when the fire extinguisher is moved to the pulled out position on the side of the housing. Refer to FIG. 29, which shows the internal structure in a partial cross section from the front, and FIG. 30, which shows the internal structure of the fire hydrant device in a partial cross section from the front when the fire extinguisher is moved onto the road surface of the lifeguard passage.

As shown in FIG. 28, two fire hydrant moving mechanisms 200 are installed in the fire extinguisher storage section 50c of the fire hydrant device 10 using the fire extinguisher drawer structure using the rack and pinion mechanism shown in FIGS. 8 to 14. A fire extinguisher 72 is stored vertically. The fire extinguisher moving mechanism 200 has a box frame body 204 supported by a parallel link mechanism mounted on a drawer body 32 provided in a fire extinguisher drawer structure, and has two fire extinguishers in the box frame body 204. The container 72 is placed vertically.

When a road user uses a fire extinguisher, for example, when the road user operates the take-out switch 27 provided on the electrical door 18 and turns on the fire extinguisher, the fire extinguisher is pulled out by the drive of the rack and pinion mechanism, as shown in FIG. The main body 32 is pulled out to an external pull-out position on the left side of the first housing 11b. Subsequently, as shown in FIG. 30, the box frame body 204 is moved to a position on the road surface of the lifeguard passageway 35 by the forward rotation of the parallel link mechanism of the fire extinguisher moving mechanism 200, and the fire extinguisher 72 is removed. It becomes possible.

[m. Configuration of fire extinguisher moving mechanism]
The configuration of the fire extinguisher moving mechanism will be explained in more detail. The explanation includes Figure 31, which shows the internal structure of the fire hydrant system from the side before the fire extinguisher is pulled out, and Figure 31, which shows the internal structure of the fire hydrant system from the side when the fire extinguisher moves onto the road surface of the lifeguard passage. Figure 32 shows a cross section, Figure 33 shows a fire extinguisher moving mechanism installed in the fire extinguisher drawer structure taken out, Figure 34 shows a perspective view of the state before the fire hydrant moving mechanism is moved, and after the fire hydrant moving mechanism moves. Refer to FIG. 35, which shows a perspective view of the state. In addition, FIGS. 33(A), (B), (C), and (D) show the left side, front, right side, and plane of the fire extinguisher drawer structure, and FIG. 33(E) shows FIG. 33(C). Part C is shown enlarged.

As shown in FIG. 33, the fire extinguisher moving mechanism 200 of this embodiment is composed of a parallel link mechanism including a base 202 and a box frame 204.

(m1. box frame)
The box frame body 204 provided in the fire extinguisher moving mechanism 200 will be explained in more detail. As shown in FIGS. 33 to 35, the box frame body 204 is opened forward and upward, and can be used as a container or a container, for example, in which two fire extinguishers can be placed vertically and can be taken out from the outside. It is a storage box. Further, as shown in FIGS. 33(B) and 33(D), a holder 222 for removably holding two fire extinguishers in a vertical position is provided at a predetermined height position on the inner back surface of the box frame body 204. ing.

(m2.Parallel link mechanism)
The parallel link mechanism of the fire extinguisher moving mechanism 200 will be explained in more detail. As shown in FIG. 33, the parallel link mechanism of the fire extinguisher moving mechanism 200 includes a base 202, two sets of left and right first horizontal links 206 and second horizontal links 208, and a box frame 204.

As shown in FIGS. 33 and 34, the base 202 is a member that fixes the fire extinguisher moving mechanism 200 on the drawer main body 32 of the fire extinguisher drawer structure, and is open at the front, rear and top, and has both sides open to the bottom. It is a box-shaped member that stands upright.

The lower end sides of the first horizontal link 206 and the second horizontal link 208 are rotatably supported on the base 202, and the upper end sides of the first horizontal link 206 and the second horizontal link 208 are rotatably supported on the box frame body 204. be supported. That is, the first horizontal link 206 has a lower end supported by a fulcrum shaft 210 on the rear end side of the base 202, and an upper end supported by a fulcrum shaft 214 on the rear end side of the upper side surface of the box frame body 204. The second horizontal link 208 has a lower end supported by a fulcrum shaft 212 on the front end side of the base 202, and an upper end supported by a fulcrum shaft 216 on the front end side of the upper side surface of the box frame body 204.

Here, the parallel link mechanism connects four links including the first horizontal link 206 and the second horizontal link 208 in a parallelogram. A lower link is virtually formed by a portion of the base 202 between the fulcrum shaft 210 at the lower end, the second horizontal link 208 rotatably supported by the base 202, and the fulcrum shaft 212 at the lower end. Also, the box frame is connected between the fulcrum shaft 214 at the upper end of the first horizontal link 206 that is pivotally supported by the box frame 204 and the fulcrum shaft 216 at the upper end of the second lateral link 208 that is pivotally supported by the box frame 204. A portion 204 virtually forms an upper link.

Therefore, as shown in FIG. 34, the box frame body 204 on which the fire extinguisher 72 is placed is supported in a suspended state from the base 202 by the first horizontal link 206 and the second horizontal link 208 in the initial state. As shown in FIG. 35, as the first horizontal link 206 and the second horizontal link 208 rotate forward, they move forward and downward while maintaining their posture.

Further, the first horizontal link 206 is provided with a biasing member that biases the first horizontal link 206 to rotate forward about the fulcrum shaft 210 . Although the structure and type of the biasing member are arbitrary, for example, a coiled spring 218 is provided. The coil spring 218 is wound around the fulcrum shaft 210 , one end is fixed to the fulcrum shaft 210 , and the other end is pressed against the rear side of the first horizontal link 206 . Similarly, the second horizontal link 208 is also provided with a coil spring 220 as a biasing member that biases the second horizontal link 208 to rotate forward about the fulcrum shaft 212 . Note that the biasing member may be provided on either one of the first horizontal link 206 and the second horizontal link 208 instead of both.

Further, as shown in FIG. 32, the fire extinguisher moving mechanism 200 is provided with a swinging damper 244 that functions as a shock absorber at the pivot point 212. The structure of the swinging damper 224 is well known. For example, oil is filled between an external stator and an internal rotor, and an orifice is provided in a protrusion of the rotor that slides on the inner periphery of the stator. Torque is generated by restricting the oil flow caused by relative rotation using an orifice.

Therefore, when the box frame body 204 on which the fire extinguisher 72 is mounted moves forward due to the rotation of the first horizontal link 206 and the second horizontal link 208, the swinging damper 224 moves the orifice flow path of the rotor. The movement of the stator is suppressed by the flow resistance of the flowing oil, and no impact occurs when the box frame body 204 on which the fire extinguisher 72 is mounted is moved forward at a gentle speed and positioned on the road surface of the lifeguard passageway 35. It looks like this.

Note that the swing damper 224 may be installed at any position, and may be installed at the fulcrum shafts 210, 212 at the lower ends of the first horizontal link 206 and/or the second horizontal link 208. Further, the shock absorbing device of the fire extinguisher moving mechanism 200 is not limited to the swinging damper 224, and may be, for example, a structure in which piston dampers are connected.

(m3.Fixing mechanism)
The fixing mechanism provided in the fire extinguisher moving mechanism 200 will be explained in more detail. In this description, reference will be made to FIG. 36, which shows a fixing mechanism that releases the fixation of the box frame by pushing the operating knob. Note that FIG. 36(A) shows a fixed state, and FIG. 36(B) shows a released state.

As shown in FIG. 31, the fixing mechanism of the fire extinguisher moving mechanism 200 is such that when the box frame 204 is in the initial position above the base 202 by the parallel link mechanism, the box frame 204 is fixed by the parallel link mechanism and the coil spring. When the forward movement of the box frame 204 is fixed and the drawer main body 32 is pulled out to the drawer position on the side of the case by the fire extinguisher drawer structure, the forward movement of the box frame 204 is released and the box frame 204 to the front.

Although the structure and function of the fixing mechanism are arbitrary, for example, as shown in FIG. 36(A), it is composed of a fixing lever 226 provided on the base 202 side, a shaft 230, and an electromagnetic solenoid 232.

The fixing lever 226 has a fixing claw 228 formed upward at the tip of the lever, and is rotatably supported by a shaft 230 on the inner side surface of the base 202 . Further, the electromagnetic solenoid 232 is fixed to the rear of the bottom of the base 202, and a drive shaft that is drawn in when energized is connected to the rear lower side of the fixed lever 226.

Therefore, as shown in FIG. 28, when the drawer main body 32 is stored in the fire extinguisher storage section of the second housing 11b, the electromagnetic solenoid 232 is de-energized, as shown in FIG. 36(A). , the drive shaft is pushed forward, so that the fixing claw 228 of the fixing lever 226 comes into contact with the bottom tip of the box frame 204, and the box frame 204 is fixed at the initial position so as not to move forward. There is.

On the other hand, as shown in FIG. 29, when the drawer main body 32 is pulled out to the pulled-out position outside the side of the second casing 11b by the rack and pinion mechanism, movement to the pulled-out position is detected, and as shown in FIG. 36(B). As shown, when the electromagnetic solenoid 232 is energized and the drive shaft is pulled in, the fixing lever 226 is rotated clockwise, and the fixing claw 228 comes off the bottom tip of the box frame body 204 and the box frame is removed. The fixation of the body 204 to the initial position is released, and as shown in FIG. (clockwise), the box frame body 204 on which the fire extinguisher 72 is placed vertically moves onto the road surface of the lifeguard passageway 35, making it easy to take out the fire extinguisher. becomes possible.

(m4. Height of lower link of parallel link mechanism)
Next, the height of the lower link of the parallel link mechanism for allowing the lower part of the box frame body 204 to pass without contacting the base 202 will be explained in more detail. In this description, reference is made to FIG. 37, which shows the arrangement (positional relationship) of the parallel link mechanism that moves the lower part of the box frame body so as not to contact the base.

As shown in FIG. 37, the fire extinguisher moving mechanism 200 pivotally supports the lower ends of the first horizontal link 206 and the second horizontal link 208 of the parallel link mechanism, and rotates forward to move the first horizontal link 206 and the second horizontal link. When moving the box frame body 204 that is pivotally supported in a suspended state from the upper end of the horizontal link 208 onto the road surface of the guard passageway 35 in front, the bottom lower surface 2040 of the box frame body 204 touches the bottom upper surface 2020 of the base 202. You need to avoid contact. Note that the lower link 207 is virtually formed by the base 202, and the upper link 209 is virtually formed by the box frame 204.

Here, FIG. 37 shows a state in which the rear part of the box frame body 204 has moved to a position matching the front end of the base 202, and at this time, the rear end of the bottom lower surface 2040 of the box frame body 204 is It is necessary to determine the height Lx to avoid contact with the tip of the bottom upper surface 2020, that is, the height Lx from the bottom upper surface 2020 of the base 202 to the lower link 207 of the parallel link mechanism.

Here, the length of the second horizontal link 206 is L, the length of the lower link 207 is W, the inclination angle of the second horizontal link 208 when the box frame 204 moves to the tip of the base 202 is θ, and the lower link 207 is The horizontal distance between the link 207 and the upper link 209 to the front and rear ends of the box frame 204 is W1, and the distance from the upper end of the box frame 204 to the base 202 when the second horizontal link 208 is at the inclination angle θ is W1. If the vertical height to the bottom upper surface 2020 of is L1, and the vertical distance from the first horizontal link 206 and second horizontal link 208 to the upper and lower ends of the box frame body 204 is L2, then the following formula The following relationship is obtained.
Lcosθ=W+3・W1 (Formula 1)
θ=cos ^-1 (W+3・W1)/L (Formula 2)
Lsinθ=L1-L2-Lx (Formula 3)
Lx=L1-L2-Lsinθ (Formula 4)
That is, since L, W, W1, and L2 are given as constants, the height Lx can be determined by determining the inclination angle θ from (Formula 2) and substituting it into (Formula 4).

Here, as shown for the box frame 204 in the initial position, the height Lx from the lower link 207 to the bottom top surface 2020 of the base 202 is equal to L2 from the bottom bottom surface 2040 of the box frame 204 to the bottom top surface 2020 of the base 202 The height Ls to the top surface 2020 is added (L2+Ls),
Lx≦(L2+Ls)
If this relationship exists, the parallel link mechanism can move the box frame 204 forward without bringing the box frame 204 into contact with the base 202.

(m5. Control unit of fire extinguisher drawer mechanism equipped with fire extinguisher moving mechanism)
A control unit of a fire extinguisher drawer structure using a rack and pinion mechanism equipped with a fire extinguisher moving mechanism will be described in more detail. In this description, reference is made to FIG. 38, which shows a control section of a fire extinguisher drawer structure equipped with a fire extinguisher moving mechanism and a rack and pinion mechanism. Note that FIG. 38(A) shows a control section using a computer circuit, and FIG. 38(B) shows a control section using a relay circuit.

The control unit controls the movement of the drawer body 32 in the pull-out direction or the pull-in direction in accordance with the operation of the switch, and also releases the fixation of the fire extinguisher moving mechanism 200 when the drawer body 32 is moved to the pull-out position. The structure and function are arbitrary, but as shown in FIG. 38(A), for example, as shown in FIG. It is composed of a two-position detector 84, a motor 80, a rack and pinion mechanism 88, an electromagnetic solenoid 232, a fixing mechanism 234, and a control circuit section 85.

Here, the drawer main body 32 is moved in the pull-out direction or the pull-in direction by the take-out switch 27, the storage switch 29, the first position detector 82, the second position detector 84, the motor 80, the rack and pinion mechanism 88, and the control circuit section 85. Since the control to do this is the same as that shown in FIG. 15(A), the explanation thereof will be omitted, and the control of the fire extinguisher moving mechanism 200 by the electromagnetic solenoid 232 and the fixing mechanism 234 will be explained.

When the control circuit section 85 detects the operation of the ejection switch 27, the control circuit section 85 rotates the motor 80 in the forward direction, drives the rack bar 76 in the drawing direction by the rotation of the pinion gear 78 of the rack and pinion mechanism 88, and the drawer main body 32 is ejected. When the drawer body 32 moves to the position, a detection signal is obtained from the first position detector 82, and the control circuit section 85 stops driving the motor 80, and stops the drawer main body 32 at the extraction position outside the side surface of the casing.

When the control circuit unit 85 receives a detection signal from the first position detector 82 during movement to the drawn-out position, it energizes the electromagnetic solenoid 232 and rotates the fixed lever 226 as shown in FIG. 36(B). The fixing by the fixing claws 228 is then released, and the box frame body 204 on which the fire extinguisher is mounted is moved onto the observer's path by the parallel link mechanism.

In addition, in the relay circuit functioning as a control section of the rack and pinion mechanism shown in FIG. A limit switch LS2, a relay X having relay contacts X1, X2, and X3, and a relay Y having relay contacts Y1, Y2, and Y3 are the same as those shown in FIG. Correspondingly, a time relay T including time contacts T1 and T2 and a limit switch LS3 of an a contact that is interlocked with a limit switch LS1 of a b contact that functions as the first position detector 82 are newly provided.

The drawer control by turning on the takeout switch 27 of the relay circuit and the retracting control of the storage switch 29 are the same as those shown in FIG. 15(B), so the explanation thereof will be omitted. When the drawer main body 32 moves to the external pull-out position on the side of the housing and stops due to the operation of the relay circuit by the pull-out switch 27, the limit switch LS3 turns on in conjunction with the turn-off of the limit switch LS1, and activates the time relay T. Then, timer contacts T1 and T2 turn on.

When the time relay T is turned on and the electromagnetic solenoid 232 is energized, the fixing by the fixing lever 226 is released, and the box frame 204 on which the fire extinguisher is placed moves onto the observer's path by the parallel link mechanism. The time relay T turns off after a predetermined period of time after being turned on, turns off the time contacts T1 and T2, stops energizing the electromagnetic solenoid 232, and suppresses current consumption.

In addition, when replacing the fire extinguisher with a new one and storing it after using the fire extinguisher, when the administrator pushes the box frame body 204 back to the initial position above the drawer body 32, it will be fixed by the fixing mechanism, and it will be fixed in this state. By mounting a new fire extinguisher on the box frame body 204 and turning on the storage switch 29, the drawer main body 32 can be pulled into and stored in the fire hydrant storage section 50c in the second housing 11b.

In addition, the fire extinguisher moving mechanism 200 shown in FIGS. 28 to 35 takes as an example the case where the drive part of the fire extinguisher drawer structure is a rack and pinion mechanism, but the pulley mechanism, plunger mechanism, and plunger mechanism shown in FIGS. 16 to 27, The same applies to the gas damper mechanism and the feed screw mechanism.

[n. Fire hydrant device equipped with a fire extinguisher drawer structure that allows the fire extinguisher to be placed horizontally]
A fire hydrant device equipped with a fire extinguisher drawer structure for horizontally placing a fire extinguisher will be described in more detail. In this explanation, Figure 38 shows a fire hydrant device in which a fire extinguisher is placed horizontally, with the fire extinguisher stored, Figure 39 shows a fire hydrant device in which the fire extinguisher is placed horizontally, and the fire extinguisher is drawn out, Refer to FIG. 40, which shows the internal structure of a fire hydrant device in which a fire extinguisher is placed horizontally, from the front with the forward-tiling door open, and FIG. 41, which shows a plan view of the internal structure of a fire hydrant device in which a fire extinguisher is placed horizontally.

As shown in FIG. 38, the casing of the fire hydrant device 10 of this embodiment is divided into a first casing 11a and a second casing 11b.
