Description

[Technical Field]

[0001] The present invention relates to a fire hydrant device that is installed in a predetermined protected area such as indoors. [Background technology]

[0002] Conventionally, as a fire hydrant device known as an indoor fire hydrant, for example, the fire hydrant device shown in Fig. 16 is known. Note that Fig. 16(A) shows the front (front face), and Fig. 16(B) shows the plan (top face).

[0003] 16, the X, Y, and Z directions are perpendicular to each other. Specifically, the surface on which the hydrant door is provided is the front surface of the fire hydrant device, and when viewed from the front, the X direction is the left-right direction, the Y direction is the up-down direction, and the Z direction is the front-to-back direction. The +X side of the X direction is the right side, the -X side is the left side, the +Y side of the Y direction is the top side, the -Y side is the bottom side, and the +Z side of the Z direction is the front side, and the -Z side is the rear side. This also applies to FIGS. 1 to 15, which are embodiments of the present invention.

[0004] 16(A), a fire hydrant device 100, which is an indoor fire hydrant, is installed, for example, in the wall of a hallway in a building at predetermined intervals, for example, at intervals of 25 m horizontally, either embedded or exposed, and has a fire hydrant door 106 that can be opened sideways, for example, to the right, at a front opening 104 of a box-shaped housing 102. In addition, an emergency call door 124 is provided at the top of the housing 102, and emergency call door 124 is provided with a red indicator light 125, a transmitter 126, and an audio unit 128 with a built-in speaker.

[0005] Also, publicly known outdoor fire hydrants include Type 1 hydrants, which are standardized to be operated by two people using flat hoses (installation intervals of 40m horizontally, hose length of 40m (20m x 2), water discharge of 350 liters / minute or more), Type 2 hydrants, which are standardized to be operated by one person using a shape-retaining hose (installation intervals of 15m horizontally, hose length of 20m, water discharge of 60 liters / minute or more), wide-area Type 2 hydrants, which are standardized to be operated by one person using a shape-retaining hose (installation intervals of 25m horizontally, hose length of 30m, water discharge of 80 liters / minute or more, operated by one person), and, for Type 1 hydrants, easy-to-operate Type 1 hydrants, which are standardized to be operated by one person using a shape-retaining hose (installation intervals of 25m horizontally, hose length of 30m, water discharge of 130 liters / minute or more).

[0006] If a fire breaks out in the protected area, the operator in charge of firefighting activities opens the fire hydrant door 106, and if the hydrant can be operated by one person, he or she takes out the water discharge nozzle attached to the end of the fire hose stored in the housing 102, and turns the handle of the fire hydrant valve to open it, which automatically starts the fire pump and supplies fire water to the fire hose.The operator then pulls out the fire hose and heads toward the location of the fire, and performs firefighting activities by discharging fire water from the water discharge nozzle.

[0007] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-223447 [Patent Document 2] Japanese Patent Publication No. 2024-002731 Summary of the Invention [Problem to be solved by the invention]

[0008] However, in conventional fire hydrant devices, the hydrant door is sized to fit the front opening, which occupies most of the front of the housing, and when it opens sideways around either the left or right side edge, the space required to open and close the hydrant door 106 must be a wide semicircular area with a radius equal to the width (width in the left-right direction) of the hydrant door in a plan view.If an object is temporarily placed near the hydrant device, there is a high possibility that the opening of the hydrant door will be obstructed, which could slow down firefighting activities.

[0009] In addition, in an emergency situation such as a fire, a user in a hurry to operate the hydrant door may open it with more force than necessary. Because the hydrant door is large, if it is opened with too much force, it may reverse from the fully open position and bounce back, hitting the user and causing injury, which could impede rapid firefighting efforts.

[0010] The present invention aims to provide a fire hydrant device that reduces the space required to open and close the fire hydrant door and improves operability. [Means for solving the problem]

[0012] (Opening configuration) The opening is divided into a central opening and two side openings adjacent to the left and right of the central opening, A hose outlet is formed in the central opening, and a fire hydrant door is provided. Each of the side openings is closed by a facing plate.

[0013] (Side-opening fire hydrant door) The fire hydrant door is a door that opens sideways to either the left or right.

[0014] (Double-hinged fire hydrant door) The fire hydrant door is a double-hinged door consisting of a door located on the left side that opens to the left and a door located on the right side that opens to the right.

[0015] (Fire hydrant door located above the central opening) The fire hydrant door and the hose outlet are located in a predetermined area above the central opening, The fire hydrant door is a door that opens sideways to either the left or right, or a door that opens downwards. The area of ​​the central opening where the hydrant door and hose outlet are not located is closed off by exterior panels.

[0016] (Fire hydrant door located partly above the opening) A hose outlet is formed and a fire hydrant door is provided in a predetermined area above the opening (front opening), The fire hydrant door is a door that opens sideways to either the left or right, or a door that opens downwards. The areas of the opening where the hydrant door and hose outlet are not located are closed off with exterior panels.

[0017] (Hose guide at hose outlet) A hose guide is provided on the left and right side edges and / or bottom edge of the hose outlet to guide the fire hose when pulling it out from inside the device to the outside.

[0018] (Arrangement of water nozzles connected to fire hoses) A water nozzle is connected to the end of the fire hose. The water discharge nozzle is detachably held in a nozzle holder arranged on the back surface of the fire hydrant door.

[0019] (Fire hydrant valve placement) As a fire hydrant equipment, a fire hydrant valve is installed inside the device to control the supply and stop of fire water to the fire hose. The hydrant valve is provided in a position that is visible from outside the device when the hydrant door is open.

[0020] (Storage of fire hoses by inclined overlapping winding) The fire hose is stored in an inclined overlap winding in which it is wound in layers from the bottom of the device upwards at a predetermined inclination angle relative to the bottom of the device.

[0021] (Hose storage structure with angled winding) a tilting member having a tilted surface at a predetermined tilt angle relative to the bottom of the interior of the device is provided at the bottom of the interior of the device; The fire hose is stored in an inclined overlap winding by being stacked on the inclined member.

[0022] (Length of inclined surface) The length of the inclined surface in the direction forming a predetermined inclination angle with respect to the bottom inside the device is set to a length equal to or greater than a predetermined allowable bending diameter at which the fire hose stored in the inclined overlap winding will not bend.

[0023] (Angle of the inclined plate) The predetermined inclination angle of the inclined surface relative to the bottom of the inside of the device is: If the depth inside the device is L and the allowable bend diameter of the fire hose is D, θ=cos -1 (L / D) The angle is set to be equal to or larger than the inclination angle θ obtained by

[0024] (Storage of fire hoses by parallel overlapping winding) The fire hose is stored in a parallel overlapping winding in which it is wound in layers from the bottom of the device interior upward in parallel to the bottom of the device interior. [Effects of the Invention]

[0025] (Effect of fire hydrant devices) The present invention provides a fire hydrant device equipped with a fire hydrant including a fire hose inside the device, in which a hose outlet is formed in a portion of an opening formed in a predetermined surface, allowing the fire hose to be freely pulled out, and a fire hydrant door is provided that can be opened and closed freely, and the fire hose is stored so that it can be freely pulled out from inside the device to outside the device through the hose outlet when the fire hydrant door is open. This makes the fire hydrant door smaller than conventional fire hydrant doors, reduces the space required for opening and closing the fire hydrant door, and makes it possible to suppress or prevent the opening of the fire hydrant door from being obstructed by objects placed near the fire hydrant device. In addition, the fire hydrant door is lightweight, making it easy to open and close, allowing for reliable response even in situations where urgent operation is required, such as when a fire breaks out.

[0026] (Effect of opening configuration) In addition, the opening is divided into a central opening and two side openings adjacent to the left and right of the central opening, and a hose outlet is formed in the central opening and a hydrant door is provided therein. Each of the side openings is closed by an exterior panel, so the width (width in the left-right direction) of the hydrant door is determined by the size of the width of the central opening, and the width of the hydrant door can be made sufficiently small compared to the width of the opening, reducing the amount of the hydrant door that projects when opened and significantly reducing interference with objects, etc. near the hydrant device.

[0027] (Effect of side-opening fire hydrant doors) Furthermore, since the fire hydrant door is a door that opens sideways to either the left or right, the amount of the fire hydrant door that projects to either the left or right when it is opened by opening it sideways as in conventional fire hydrant devices is reduced, making it possible to significantly reduce interference with objects near the fire hydrant device.

[0028] (The effect of double-hinged fire hydrant doors) In addition, the fire hydrant door is composed of a door located on the left side that opens to the left and a door located on the right side that opens to the right, and is a door that opens in both directions, so compared to when the fire hydrant door opens to the left or right, the amount of the fire hydrant door that projects to the left or right when opened can be further reduced, making it possible to significantly reduce interference with objects near the fire hydrant device.In addition, the space required to open and close the fire hydrant door can be further reduced compared to when the fire hydrant door opens to the left or right.

[0029] (Effect of a fire hydrant door located partly above the central opening) In addition, the hydrant door and the hose outlet are located in a predetermined area above the central opening, and the hydrant door is a door that opens sideways to the left or right, or a door that opens downwards, and the area of ​​the central opening where the hydrant door and the hose outlet are not located is closed off with an exterior panel, so the vertical width (width in the up and down direction) of the hydrant door can be made small, and by positioning the hydrant door at an upper position, the amount of the hydrant door that pops out when opened is further reduced, and interference with objects near the hydrant device can be greatly reduced. In addition, the hydrant door is made even lighter, which further improves operability.

[0030] (Effect of a fire hydrant door located partly above the opening) In addition, a hose outlet is formed and a hydrant door is provided in a specified area above the opening (front opening), and the hydrant door is a door that opens sideways to either the left or right, or a door that opens downwards, and the area of ​​the opening where the hydrant door and hose outlet are not located is closed off by an exterior panel, so that, as with conventional fire hydrant devices, even if the hydrant door has the same width as the opening, the vertical width of the hydrant door can be made sufficiently smaller than the vertical width of the opening, and also, because the hydrant door is positioned above, the amount of the hydrant door that pops out when it is opened is reduced, and interference with objects near the hydrant device can be greatly reduced.

[0031] (Effect of the hose guide at the hose outlet) In addition, hose guides are provided on the left and right side edges and / or bottom edge of the hose outlet to guide the fire hose when it is pulled out from inside the device to the outside, making it possible to smoothly pull out the fire hose even with the shape-retaining hose of a wide-range No. 2 fire hydrant or an easy-to-operate No. 1 fire hydrant, which are intended to be operated by one person, and reducing wear on the fire hose due to friction caused by contact with the hose guides.

[0032] (Effect of arrangement of water nozzles connected to fire hoses) In addition, a water discharge nozzle is connected to the tip of the fire hose, and the water discharge nozzle is detachably held in a nozzle holder located on the back side of the hydrant door. Therefore, when the hydrant door is opened, the water discharge nozzle held in the nozzle holder on the back side of the hydrant door is exposed, making it possible to simply and easily remove the water discharge nozzle.

[0033] (Effect of fire hydrant valve placement) In addition, as a fire hydrant equipment, a fire hydrant valve that controls the supply and stop of fire water to the fire hose is provided inside the device, and the fire hydrant valve is provided in a position that is visible from outside the device when the fire hydrant door is opened, so that users can see the fire hydrant valve when the fire hydrant door is opened, making it possible to operate the fire hydrant valve simply and easily.

[0034] (Effect of storing fire hoses by overlapping winding at an angle) In addition, the fire hose is stored in an inclined overlapping state, wound in layers from the bottom of the device upward at a predetermined inclination angle relative to the bottom of the device, which reduces the depth (width in the front-to-back direction) of the device and allows the fire hose to be stored in an overlapping state by being smoothly bent without bending inside the device, and also allows the fire hose to be pulled out smoothly when the fire hydrant door is opened.

[0035] (Effect of the hose's angled storage structure) In addition, an inclined member having an inclined surface at a predetermined angle to the bottom of the device is provided at the bottom inside the device, and the fire hose is stored in an inclined overlapping manner by being stacked on the inclined member, making it possible to store the fire hose in an inclined overlapping manner with a simple structure.

[0036] (Effect of the length of the inclined plane) In addition, the length of the inclined surface in the direction that forms a predetermined inclination angle with respect to the bottom inside the device is set to a length that is equal to or greater than the predetermined allowable bending diameter at which the fire hose stored in the inclined overlapping winding will not bend. Therefore, when the fire hose is stored in the inclined overlapping winding, the fire hose will not bend, and can be stored in an overlapping winding state with smooth bending.

[0037] (Effect of inclination angle of inclined surface) The specified inclination angle of the inclined surface relative to the bottom of the device is θ=cos -1 Since the inclination angle is set to be equal to or greater than the inclination angle θ calculated by (L / D), when the specified inclination angle relative to the bottom inside the device is set to be equal to or greater than the inclination angle θ, it is possible to ensure that the length of the inclined surface of the inclined member is equal to or greater than the allowable diameter of the bend. Therefore, even if the depth inside the device is less than the allowable diameter of the bend of the fire hose due to the thinning of the fire hydrant device, the fire hose can be stored in an inclined, overlapping wound state without bending.

[0038] (Effect of storing fire hoses by parallel overlapping winding) Furthermore, the fire hose is stored in a parallel overlapping winding in which it is wound in layers from the bottom of the device upward in parallel to the bottom of the device, so that the fire hose can be stored in an overlapping winding state by smoothly bending it without bending it inside the device, and also when the fire hydrant door is opened and the fire hose is pulled out, it can be pulled out smoothly.

[0040] Hereinafter, an embodiment of a fire hydrant device according to the present invention will be described with reference to the drawings. However, the present invention is not limited to the following embodiment.

[0041] [Basic concept of the embodiment] First, the basic concept of the embodiment will be described. The embodiment generally relates to a fire hydrant device installed in a predetermined protected area.

[0042] Here, a "protected area" refers to a designated outdoor or indoor area of ​​a certain extent that envisages a fire prevention object or part thereof, or each part of a building, that is protected from abnormalities such as fires by installing disaster prevention equipment such as fire hydrants, and is a concept that includes areas such as rooms, corridors, and staircases of a building.

[0043] In addition, the term "fire hydrant device" refers to a device that is installed in a protected area, has fire hydrant equipment including a fire hose inside the device, and is a concept that includes fire hydrant devices intended for indoor fire hydrants such as No. 1 fire hydrant, No. 2 fire hydrant, wide-area No. 2 fire hydrant, or easy-to-operate No. 1 fire hydrant, and is a concept that includes fire hydrant facilities with fire hydrant devices installed.

[0044] The fire hydrant device of this embodiment is characterized in that a hose outlet that allows the fire hose to be freely pulled out is formed in a part of an opening formed on a specified surface, and the fire hydrant door is provided so as to be freely opened and closed, and the fire hose is stored so as to be freely pulled out from inside the device to outside the device through the hose outlet when the fire hydrant door is opened.

[0045] The "hose outlet" is an opening formed by opening the hydrant door or an opening corresponding to a partial area thereof. In a specific embodiment, the predetermined surface on which the opening is formed and on which the hydrant door is provided is the front surface of the fire hydrant device, and the opening is referred to as the "front opening."

[0046] The opening (front opening) is divided into a central opening and two side openings adjacent to the left and right of the central opening, with a hose outlet formed in the central opening and a fire hydrant door installed, and each of the side openings being closed by exterior panels.

[0047] Here, the central opening and the two left and right side openings do not necessarily have to be physically separated openings, and are shown as virtually (conceptually) separated openings for the sake of explanation. Also, the "exterior panel" is a member for closing the area of ​​the opening where the hydrant door is not installed, and it is desirable that it be fixed so that it can remain closed when the user pulls out the fire hose from inside the device, but the fire hydrant device may also be equipped with a structure that allows the exterior panel to be released and opened depending on the situation, such as when rewinding the fire hose into the device.

[0048] Furthermore, when the fire hydrant door is a door installed in the central opening, the door structure may be, for example, a door that opens sideways to either the left or right, and in a specific embodiment, a fire hydrant device in which a fire hydrant door that opens sideways to the right is installed in the central opening is referred to as the "first embodiment of the fire hydrant device."

[0049] In addition, the fire hydrant door may have other door structures, such as a door that is composed of two doors, one located on the left side that opens horizontally to the left and one located on the right side that opens horizontally to the right, making it a double-hinged door.In a specific embodiment, a fire hydrant device in which a double-hinged fire hydrant door is provided at the central opening is referred to as the ``second embodiment of the fire hydrant device.''

[0050] For this reason, compared to conventional fire hydrant devices, the "first embodiment of the fire hydrant device" and the "second embodiment of the fire hydrant device" reduce the space required to open and close the hydrant door and the amount of the hydrant door that projects to the left and right when opened, significantly reducing interference with objects near the fire hydrant device. Furthermore, the smaller and lighter fire hydrant door makes it easier to open and close the fire hydrant door, enabling reliable response even in situations where urgent action is required, such as in the event of a fire. Furthermore, the "second embodiment of the fire hydrant device" in which the hydrant door opens on both sides further reduces the space required to open and close the fire hydrant door and the amount of the fire hydrant door that projects to the left and right when opened, compared to the "first embodiment of the fire hydrant device" in which the fire hydrant door opens to the side.

[0051] In addition, the fire hydrant door may be provided in a specified region above the central opening, for example, within the region within the upper half of the central opening, and may be a door that opens sideways to either the right or a door that opens downwards.In specific embodiments, a fire hydrant device in which a fire hydrant door that opens sideways to the right is provided in the upper half of the central opening is referred to as the "third embodiment of the fire hydrant device," and a fire hydrant device in which a fire hydrant door that opens downwards is provided in the upper half of the central opening is referred to as the "fourth embodiment of the fire hydrant device."

[0052] For this reason, the "third embodiment of the fire hydrant device" and the "fourth embodiment of the fire hydrant device" are installed in the upper half, which is a predetermined area above the central opening, and therefore it is possible to further reduce the space required to open and close the fire hydrant door and make the fire hydrant door lighter than the "first embodiment of the fire hydrant device" and the "second embodiment of the fire hydrant device." Also, in the "fourth embodiment of the fire hydrant device," in which the fire hydrant door opens downward, the fire hydrant door does not pop out to the left or right when opened.

[0053] Furthermore, the opening (front opening) is not divided into a central opening and two side openings, left and right, and the hydrant door is provided in a specified area above the opening (front opening), for example, in an area within the upper half of the opening (front opening), and may be a door that opens sideways to either the left or right, or a door that opens downwards; in a specific embodiment, a fire hydrant device in which a downward-opening fire hydrant door is provided in the upper half of the opening (front opening) is referred to as the "fifth embodiment of the fire hydrant device."

[0054] For this reason, in the "fifth embodiment of the fire hydrant device," the width of the fire hydrant door is the same as that of the opening (front opening), but it is located in the upper half of the opening (front opening), and the vertical width of the fire hydrant door can be made sufficiently smaller than the vertical width of the opening, which makes it possible to reduce the space required to open and close the fire hydrant door and make the fire hydrant door lighter than conventional fire hydrant devices.

[0055] In a specific embodiment, "horizontal" corresponds to the direction "left and right", "vertical" corresponds to the direction "up and down (height)", and "depth" corresponds to the direction "front and back".

[0056] Furthermore, since the fire hydrant device also covers indoor fire hydrants that are expected to be operated by one person, such as No. 2 hydrants, wide-range No. 2 hydrants, and easy-to-operate No. 1 hydrants, a hose guide may be provided on the left and right side edges and / or bottom edge of the hose outlet to guide the fire hose when it is pulled out from inside the device to the outside. The shape of the hose guide is arbitrary, but since the hose guide allows the fire hose to be pulled out smoothly and reduces wear on the fire hose due to friction caused by contact with the hose guide, it includes, for example, a cylindrical or columnar member.

[0057] A water discharge nozzle is connected to the end of the fire hose, and the water discharge nozzle is detachably held in a nozzle holder located on the back surface of the hydrant door. In the "second embodiment of the fire hydrant device" in which the hydrant door opens on both sides, the hydrant door is composed of two doors, but a nozzle holder may be provided on the back surface of only one of the doors, or nozzle holders may be provided on the back surfaces of both doors, making it possible to select which nozzle holder holds the water discharge nozzle.

[0058] Furthermore, a fire hydrant valve that controls the supply and stop of fire water to the fire hose is provided inside the device as a fire hydrant device, and the fire hydrant valve is provided in a position that can be seen from outside the device when the hydrant door is open. That is, in the "First Embodiment of the Fire Hydrant Device" and the "Second Embodiment of the Fire Hydrant Device," the fire hydrant valve is provided in a position that can be seen from the central opening, in the "Third Embodiment of the Fire Hydrant Device" and the "Fourth Embodiment of the Fire Hydrant Device," the fire hydrant valve is provided in a position that can be seen from the upper half of the central opening, and in the "Fifth Embodiment of the Fire Hydrant Device," the fire hydrant valve is provided in a position that can be seen from the upper half of the opening (front opening).

[0059] Furthermore, fire hydrant devices house fire hoses inside, and the hose storage structures include, for example, a "hose inclined winding storage structure" and a "hose parallel winding storage structure."

[0060] The "hose diagonal winding storage structure" is a structure for storing a fire hose in an "inclined overlapping winding" in which the hose is wound in layers from the bottom of the device upward at a predetermined angle relative to the bottom of the device. For example, an inclined member having an inclined surface at a predetermined angle relative to the bottom of the device is provided at the bottom of the device, and the fire hose is stored in an inclined overlapping winding by being stacked on the inclined member. Here, the "inclined member" may be a member of any shape, such as a plate or a right-angled triangular prism, as long as it allows the fire hose to be stored in an inclined overlapping winding.

[0061] Furthermore, the length of the inclined surface of the inclined member in a direction that forms a predetermined inclination angle with respect to the bottom inside the device is set to a length that is equal to or greater than a predetermined allowable bend diameter at which the fire hose stored in the inclined overlap winding will not bend. Note that the "length of the inclined surface in a direction that forms a predetermined inclination angle with respect to the bottom inside the device" refers to the case where the inclined member is placed at the bottom inside the device, and in a specific embodiment, refers to the length of the side that includes the front-to-back component (depth component) and the up-to-down component (height or vertical component) of the two sides that form the inclined surface.

[0062] The specified inclination angle of the inclined surface relative to the bottom of the device is, assuming that the depth of the device is L and the allowable bend diameter of the fire hose is D, θ=cos -1 (L / D) The angle is set to be equal to or larger than the inclination angle θ obtained by

[0063] The "hose parallel winding storage structure" is a structure for storing a fire hose in a "parallel overlapping winding" in which the hose is wound in layers from the bottom of the device upwards, parallel to the bottom of the device.

[0064] Note that "parallel" does not necessarily mean being strictly parallel to the object (the bottom of the device in the case of parallel overlap winding), but includes being approximately parallel to the object, and "perpendicular" does not necessarily mean being strictly perpendicular to the object, but includes being approximately perpendicular to the object.

[0065] Specific embodiments will be described below. In the specific embodiments shown below, the fire hydrant device is intended for an "indoor fire hydrant, easily operable No. 1 fire hydrant (installed at horizontal intervals of 25 m, with a hose length of 30 m, and a discharge rate of 130 liters / minute or more)," and will be described in first to fifth embodiments.

Fig. 1(A) shows the front (front face) of the fire hydrant device, and Fig. 1(B) shows the plan (top face).

[0069] As shown in Figure 1(A), the fire hydrant device 10 is intended for, for example, an easily operable No. 1 fire hydrant and has a box-shaped housing 12 that opens to the front. The size of the housing 12 is arbitrary, but for example, the height H (length in the vertical direction) is 1300 mm, the width W (length in the left-right direction) is 800 mm, and the depth L (length in the front-to-back direction) is 180 mm.

[0070] An emergency notification door 24 is provided on the upper front side of the housing 12 of the fire hydrant device 10. The emergency notification door 24 is equipped with a red indicator light 25, a transmitter 26, and an audio unit 28. The red indicator light 25 is normally always lit, allowing the location of the fire hydrant device 10 to be confirmed from a distance. When the transmitter 26 is pressed and switched on in the event of a fire or other emergency, it transmits a signal to the disaster prevention receiving panel. The disaster prevention receiving panel, upon receiving the signal, sends a fire signal to the fire hydrant starting device. The fire hydrant starting device sends a start signal to the fire pump, and by flashing the red indicator light 25 in response to a pump start confirmation signal, notifies the protected area in which the fire hydrant device 10 is installed that the pump has started. It also initiates the pressurized supply of fire water to the shape-retaining hose housed inside the housing 12. The audio unit 28 has a built-in speaker and outputs a predetermined sound or voice alarm under the control of the disaster prevention receiving panel.

[0071] A fire hydrant structure is provided below the emergency call door 24 of the housing 12. A rectangular front opening 14 is formed inside a frame having a width W0 on the front side of the housing 12 below the emergency call door 24, and a fire hydrant door 16 is provided in a central opening 1410 located in the center of the front opening 14 in the left-right direction.

[0072] The hydrant door 16 is pivotally supported on an exterior panel 18 located on the right side by torque hinges 22 provided at the top and bottom of the right edge, and can be freely opened sideways to the right as shown in Figure 1(B). A door opening / closing handle 20 is provided in the center of the left side of the hydrant door 16, and pulling the door opening / closing handle 20 towards you releases the hydrant door 16 from its closed position, allowing it to be opened. A nameplate 15 is provided in a predetermined position on the hydrant door 16, for example on the upper side.

[0073] (a2. Fire hydrant door and exterior panel) Next, the fire hydrant door and exterior panel will be explained, with reference to Figure 1.

[0074] As shown in Figure 1(A), the front opening 14 of the housing 12 is virtually divided into three sections: a central opening 1410 and left and right side openings 1412 and 1414. A fire hydrant door 16 is disposed in the central opening 1410, and exterior panels 18 are disposed in the side openings 1412 and 1414. Note that the fire hydrant door 16 can be freely opened sideways, but the exterior panels 18 are fixed to the housing 12 and keep the side openings 1412 and 1414 closed at all times.

[0075] Here, the width W1 of the central opening 1410 and the width W2 of the side openings 1412 and 1414 are arbitrary, but for example, the width W1 is set to a predetermined width within a range of 40% to 60% of the width W0 of the front opening 14, and the width W2 is set to a predetermined width within a range of 30% to 20%.

[0076] More specifically, for example, if the width W3 of the frame of the housing 12 is 25 mm, the width W0 of the front opening 14 is 750 mm, the width W1 of the central opening 1410 is 375 mm, which is 50% of the width of the front opening 14, and the width W2 of the side openings 1412 and 1414 is 187.5 mm, the width of the hydrant door 16 is the width W1 (= 375 mm) of the central opening 1410, and the width of the exterior panel 18 is the width W2 (= 187.5 mm) of the side openings 1412 and 1414. In this case, the width W of the housing 12 is W = W0 + 2 × W3 = W1 + 2 × W2 + 2 × W3 = 800 mm. Note that although the width W2 of the side openings 1412 and 1414 is the same size, they may have different widths.

[0077] (a3. Torque hinge) Next, we will explain the torque hinge that pivotally supports the fire hydrant door on the exterior panel on the right side so that the fire hydrant door can be freely opened sideways. In this explanation, refer to Figure 2, which shows the pivotal support structure of the fire hydrant device in Figure 1. Note that Figure 2(A) shows the pivotal support structure when the fire hydrant door is closed, as viewed from above, Figure 2(B) shows the pivotal support structure when the fire hydrant door is open, as viewed from above, and Figure 2(C) shows the torque hinge that realizes the pivotal support structure.

[0078] The torque hinges 22 provided at the upper and lower parts of the right edge of the fire hydrant door 16 have a structure in which blades 2210 and 2212, which have flat head screw holes 2216 at two locations, top and bottom, are pivotally supported by a shaft 2214, as shown in FIG. 2(C), and further have a known torque generating structure that holds the blades 2210 and 2212 stopped at any position when they are rotated and released, and includes, for example, a free stop hinge.

[0079] Furthermore, by fixing the blade 2210 to the left edge of the exterior panel 18 and the blade 2212 to the right edge of the hydrant door 16, for example, the torque hinge 22 can hold the hydrant door 16 in a released position (open position) when the hydrant door 16 is opened laterally to the right around the shaft 2214 of the torque hinge 22. Furthermore, as shown in Figure 2(B), the position where the hydrant door 16 is opened laterally to the right by approximately 180° is the fully open position.

[0080] When the torque hinge 22 is provided by fixing the blade 2212 to the right edge of the hydrant door 16 and fixing the blade 2210 to the left edge of the exterior panel 18, a gap corresponding to the torque range 22 is generated between the hydrant door 16 and the exterior panel 18, so a waterproof structure is provided by arranging a sealing member such as a rubber sheet on the inside of the end face of the exterior panel 18. Furthermore, the structure for opening the hydrant door 16 sideways is not limited to the torque range 22, and may include any pivot structure.

[0081] (a4. Hose storage structure with angled winding) Next, we will explain the diagonally wound hose storage structure provided as the hose storage structure of the fire hydrant device. In this explanation, reference will be made to Figure 3, which shows the diagonally wound hose storage structure. Note that Figure 3(A) shows the front (front) of the fire hydrant device of Figure 1 with the front opening open, Figure 3(B) shows the fire hydrant device of Figure 1 with the front opening open in cross section as seen from the right side, and Figure 3(C) shows the diagonally wound hose storage structure as seen from the top. Also, Figure 3(B) shows the cross section taken along the cutting line aa in Figure 3(A).

[0082] As shown in Figure 3(A), a hose storage section 30 is provided inside the housing 12 of the fire hydrant device 10, and hose guides 42 are erected on the front side of the hose storage section 30 at positions corresponding to each of the positions near the boundary between the central opening 1410 and the side openings 1412, 1414 shown in Figure 1(A), and the shape-retaining hose 32 is stored inside (rear side of) the hose guide 42 of the hose storage section 30 in a manner that allows it to be freely pulled out using a hose inclined winding storage structure.

[0083] A hose outlet is formed by two hose guides 42 and the upper and lower frames of the housing 12. For example, a cylindrical or columnar support member is used as the hose guide 42, which reduces frictional resistance when the hose guide 42 slides against the shape-retaining hose 32 as it is being pulled out, making it possible to pull out the shape-retaining hose 32 with less force and reducing wear on the shape-retaining hose 32. As shown in Figures 2(A) and (B), the hose guide 42 stands upright so that approximately half of it is located on the side of the central opening 1410 where the hydrant door 16 is provided.

[0084] A fire hydrant valve 38 is provided at a predetermined position on the upper back surface (rear face) of the housing 12, between the two hose guides 42. As shown in Fig. 3(B), a water supply pipe 44 is connected from the rear to the inlet of the fire hydrant valve 38, and the shape-retaining hose 32 is connected to the outlet of the fire hydrant valve 38. The fire hydrant valve 38 is normally closed, and when the handle is turned, for example, to the left when viewed from the front, it is opened and fire water is supplied from the water supply pipe 44 to the shape-retaining hose 32.

[0085] Furthermore, as shown in Figure 3(B), the hose inclined winding storage structure provided in the hose storage section 30 has an inclined plate 40 provided on the bottom (lower part) of the housing 12 so that the inclination angle with the bottom (lower part) inside the housing 12 is θ0 by inclining it diagonally downwards towards the front, and the shape-retaining hose 32 can be wound around on the inclined plate 40 in a layered manner from the bottom to the top along the inner wall of the housing 12 (hereinafter referred to as inclined overlap winding).

[0086] Here, when overlapping and winding the shape-retaining hose 32, the hose is curved on both the left and right sides to prevent bending, so a bending diameter of at least a predetermined allowable bending diameter D must be ensured. The shape-retaining hose used for the easy-to-operate No. 1 fire hydrant targeted in the embodiment has an outer diameter of about 30 mm and an allowable bending diameter D of about 240 mm, but because the depth L of the housing 12 is 180 mm, which is narrower than the allowable bending diameter D (= 240 mm), the shape-retaining hose 32 cannot be overlapped and wound parallel to the bottom inside the housing 12.

[0087] Therefore, in the embodiment, an inclined plate 40 is provided at the bottom of the housing 12, and the shape-retaining hose 32 is wound in an inclined overlapping manner on the inclined plate 40, thereby making it possible to store the shape-retaining hose 32 while ensuring a bending diameter greater than the allowable bending diameter D.

[0088] Here, when the plate width D0 of the inclined plate 40 is the allowable bending diameter D of the shape-retaining hose 32, the inclination angle θ is cosθ=L / D Therefore, θ=cos -1 (L / D) That is, by setting the inclination angle θ0 so that the inclination angle θ is equal to or greater than the plate width D0 of the inclined plate 40 when the allowable bending diameter D of the shape-retaining hose 32 is taken as the plate width D0, it is possible to ensure a bending diameter equal to or greater than the allowable bending diameter D.

[0089] When the allowable bending diameter D is 240 mm and the depth L of the housing 12 is 180 mm, the inclination angle θ is approximately 41°. In order to allow some leeway in the width of the inclined plate 40, for example, the inclination angle θ0 is set to approximately 45°, and the plate width D0 of the inclined plate 40 is set to 255 mm.

[0090] Here, the length per turn of the shape-retaining hose 32 wound in an inclined overlapping manner on the inclined plate 40 is approximately 1.7 m when the width of the hose storage section 30 (= width W0 of the front opening 14) is 750 mm, and a 30 m shape-retaining hose 32 can be stored with approximately 18 turns of inclined overlapping winding.

[0091] Furthermore, as shown in Figure 3(C), when the shape-retaining hose 32 is stored in the hose storage section 30 in an overlapping, diagonal winding, the shape-retaining hose 32 is curved inward at the two hose guides 42 and wound around, increasing the pressing stress on the inner wall surfaces of the curved portions on both the left and right sides, thereby suppressing and preventing the collapse of the shape-retaining hose 32 that is overlapping, diagonally wound.

[0092] (a5. Opening the fire hydrant door) Next, the opening of the hydrant door will be explained. In this explanation, reference will be made to Figure 4, which shows the fire hydrant device of Figure 1 with the hydrant door open. Figure 4(A) shows the front (front view), and Figure 4(B) shows the plan (top view).

[0093] By operating the door opening / closing handle 20 to release the fire hydrant door 16 held in the closed position, the fire hydrant door 16 can be opened sideways to the right around the torque hinges 22 provided at the upper and lower parts of the right edge as an axis, and can be opened up to a fully open position rotated by approximately 180° and held in the open position, as shown in Figure 4(A).

[0094] When the fire hydrant door 16 is opened to the fully open position, the protrusion width W4 of the open fire hydrant door 16 from the right edge of the housing 12 is W4=W1-(W2+W3) For example, if the width W1 of the central opening 1410 where the hydrant door 16 is disposed is 375 mm, the width W2 of the side openings 1412 and 1414 where the exterior panels 18 are disposed is 187.5 mm, and the frame width W3 of the housing 12 is 25 mm, the protrusion width W4 is 162.5 mm (approximately 16 cm), which makes it possible to significantly reduce the amount of protrusion of the hydrant door 16 to the right compared to the conventional fire hydrant device 100 shown in FIG.

[0095] Furthermore, as shown in Figure 4(B), the space required to open and close the fire hydrant door 16 (the area through which the fire hydrant door 16 passes) is a semicircular area in plan view with the torque hinge 22 at the center and the radius being the width W1 of the central opening 1410 where the fire hydrant door 16 is placed, which can be significantly reduced compared to the conventional fire hydrant device 100 shown in Figure 16.

[0096] This reduces or prevents the opening of the fire hydrant door from being obstructed by objects placed near the fire hydrant device, and the fire hydrant door is now lighter and narrower, making it easier to open and close, and enabling reliable response even in situations where urgent action is required, such as in the event of a fire.

[0097] As shown in Figure 4(A), a water discharge nozzle 34 is connected to the tip of the shape-retaining hose 32, and the water discharge nozzle 34 is detachably held in a nozzle holder 36 provided on the back side of the hydrant door 16. By opening the hydrant door 16, it is possible to operate a fire hydrant valve 38 provided on the back side inside the housing 12.

[0098] Therefore, when a user opens the fire hydrant door 16, the user can take out the water discharge nozzle 34 that appears in front of the user and operate the fire hydrant valve 38 to supply fire water to the shape-retaining hose 32 and discharge water from the water discharge nozzle 34.

[0099] (a6. Parallel hose storage structure) Next, we will explain the parallel hose winding storage structure provided as the hose storage structure of the fire hydrant device. In this explanation, reference will be made to Figure 5, which shows the parallel hose winding structure. Note that Figure 5(A) shows the front (front side) of the fire hydrant device of Figure 1 with the front opening open and provided with the parallel hose winding storage structure, Figure 5(B) is a cross section seen from the right side, showing the fire hydrant device of Figure 1 with the front opening open and provided with the parallel hose winding storage structure, and Figure 5(C) shows the parallel hose winding storage structure as seen from the top. Also, Figure 5(B) shows the cross section taken along the cutting line bb in Figure 5(A).

[0100] The fire hydrant device 10 has a hose diagonal winding storage structure in which the shape-retaining hose 32 is stored in the hose storage section 30 in a diagonal overlapping winding. However, as shown in FIG. 5, the shape-retaining hose 32 may be stored by being wound parallel to the bottom of the housing 12 along the inner wall of the housing 12 so as to be layered from the bottom to the top of the housing 12 (hereinafter referred to as parallel overlapping winding).

[0101] Here, as mentioned above, when the shape-retaining hose 32 is wound in an overlapping manner, the hose must be bent on both the left and right sides to prevent bending, and therefore a bending diameter of at least a predetermined allowable bending diameter D must be ensured. The shape-retaining hose used for the easily operable No. 1 fire hydrant has an outer diameter of about 30 mm and an allowable bending diameter D of about 240 mm. Therefore, when a parallel hose winding storage structure is adopted as the hose storage structure, the depth of the housing 12 must be expanded to L1, which is at least the allowable bending diameter D, and the size of the housing 12 will be larger than when an angled hose winding storage structure is adopted.

[0102] In addition, the length per turn of the shape-retaining hose 32 wound in parallel overlapping fashion is approximately 1.7 m when the width of the hose storage section 30 (= width W0 of the front opening 14) is 750 mm, just like when wound diagonally overlapping, and a 30 m shape-retaining hose 32 can be stored with approximately 18 turns of parallel overlapping fashion.

[0103] Furthermore, as in the case of diagonal overlap winding, the shape-retaining hose 32 is curved inward at the two hose guides 42 and wound around, which increases the pressing stress on the inner wall surfaces of the curved portions on both the left and right sides and suppresses and prevents the collapse of the shape-retaining hose 32, which is wound in parallel overlaps.

[0104] [b. Second embodiment of the fire hydrant device] Next, a second embodiment of the fire hydrant device will be described. The second embodiment of the fire hydrant device is characterized by a double-hinged fire hydrant door. In this description, reference will be made to Fig. 6, which shows the second embodiment of the fire hydrant device, and Fig. 7, which shows the fire hydrant device of Fig. 6 with the hydrant door open. Note that Figs. 6(A) and 7(A) show the front (front), and Figs. 6(B) and 7(B) show the plan (top). Furthermore, for components that are assigned the same reference numerals as in the first embodiment and whose description is omitted in the second embodiment, the contents described in the first embodiment are basically to be referenced.

[0105] 6(A), the fire hydrant device 10 of the second embodiment has a front opening 14 that is virtually divided into a central opening 1410 and side openings 1412, 1414, formed on the front surface of the housing 12 below the emergency notification door 24, a pair of fire hydrant doors 46 that swing both ways are arranged in the central opening 1410, and exterior panels 18 are arranged in the side openings 1412, 1414. The exterior panels 18 are fixed to the housing 12, and keep the side openings 1412, 1414 closed at all times.

[0106] The right side of the double-swinging fire hydrant door 46 is pivotally supported by torque hinges 22 provided at the top and bottom of the right edge on the exterior panel 18 located on the right side, allowing it to open sideways to the right, and the left side of the fire hydrant door 46 is pivotally supported by torque hinges 22 provided at the top and bottom of the left edge on the exterior panel 18 located on the left side, allowing it to open sideways to the left, so that the pair of fire hydrant doors 46 can be opened in both directions. In addition, each of the fire hydrant doors 46 is provided with a door opening / closing handle 20, and when the door opening / closing handle 20 is pulled toward you, the pair of fire hydrant doors 46, which are held in the closed position, are released and can be opened in both directions.

[0107] Here, in the second embodiment, as shown in FIG. 7 , when the right side of the double-hinged fire hydrant door 46 is opened laterally by approximately 180° to the right and the left side hydrant door 46 is opened laterally by approximately 180° to the left, and the fire hydrant doors 46 are opened in both directions to the fully open position, the fire hydrant door 46 does not protrude from the left and right side edges of the housing 12. For example, the width W1 of the central opening 1410 is set to 1 / 4 of the width W0 of the front opening 14, the width W2 of the side openings 1412 and 1414 is set to 1 / 4 of the width W0 of the front opening 14, and the widths W11 and W12 of the fire hydrant doors 46 are set to 1 / 2 of the width W1 of the central opening 1410. That is, W11=W12=W2=W0 / 4 The width is set so that

[0108] As a result, the pair of fire hydrant doors 46 do not protrude to the left or right sides of the housing 12, and the space required to open and close the pair of fire hydrant doors 46 (the passing area of ​​the pair of fire hydrant doors 46) is, as shown in Figure 7 (B), two semicircular areas in plan view with the torque hinge 22 as the center and the widths W11 and W12 of the pair of fire hydrant doors 46 as radii, which can be significantly reduced compared to the conventional fire hydrant device 100 shown in Figure 16.

[0109] Furthermore, a shape-retaining hose 32 is stored in a hose storage section inside the housing 12 so that it can be pulled out freely, and as shown in Figure 7(A), a water-discharge nozzle 34 is connected to the tip of the shape-retaining hose 32. The water-discharge nozzle 34 is detachably held in a nozzle holder 36 provided on the back side of the right-side fire hydrant door 46, for example, and by opening the pair of fire hydrant doors 46, it is possible to operate a fire hydrant valve 38 provided on the back side inside the housing 12.

[0110] Therefore, when a user opens a pair of fire hydrant doors 46, the user can take out the water discharge nozzle 34 that appears in front of the user and operate the fire hydrant valve 38 to supply fire water to the shape-retaining hose 32 and discharge water from the water discharge nozzle 34.

[0111] [c. Third embodiment of the fire hydrant device] Next, a third embodiment of the fire hydrant device will be described. This third embodiment of the fire hydrant device is characterized by a hydrant door that opens laterally in the upper half of the central opening. In this description, reference will be made to FIG. 8, which shows the third embodiment of the fire hydrant device; FIG. 9, which shows the fire hydrant device of FIG. 8 with the hydrant door open; FIG. 10, which shows the hose guide structure of the fire hydrant device of FIG. 8; and FIG. 11, which shows the open structure of the exterior panel of the fire hydrant device of FIG. 8. Note that FIGS. 8(A), 9(A), and 11(B) show the front (front), FIGS. 8(B) and 9(B) show the plan (top), and FIG. 11(A) shows the right side. Also, FIG. 11(A) shows a cross section taken along line cc in FIG. 11(B), with the stored shape-retaining hose omitted. Furthermore, for components that are designated with the same reference numerals as those in the first embodiment and whose description is omitted in the third embodiment, the contents described in the first embodiment are essentially the same.

[0112] As shown in FIG. 8(A), the fire hydrant device 10 of the third embodiment has a front opening 14 that is virtually divided into a central opening 1410 and side openings 1412, 1414 on the front surface of the housing 12 below the emergency call door 24, and a fire hydrant door 48 is arranged in the upper half of the central opening 1410, and exterior panels 18 are arranged on the lower half of the central opening 1410 and the side openings 1412, 1414.

[0113] The width and height of the hydrant door 48 are arbitrary, but for example, the width of the hydrant door 48 (= width of the central opening 1410) is set to W1 (= 375 mm) as in the first embodiment, and the height is set to H1 (= 450 mm), which is half the height H0 of the front opening 14, which is 900 mm. In addition, the width of the side openings 1412, 1414 is also set to W2 (= 178.5 mm) as in the first embodiment.

[0114] As in the first embodiment, the fire hydrant door 48 is pivotally supported on the exterior panel 18 by torque hinges 22 provided at the upper and lower parts of the right edge, and can be freely opened sideways to the right.

[0115] Therefore, as shown in FIG. 9, when the hydrant door 48 is opened to the fully open position by rotating it approximately 180°, as in the first embodiment, the open hydrant door 48 protrudes approximately 17 cm from the right edge of the housing 12. However, the amount of protrusion of the hydrant door 48 to the right can be significantly reduced compared to the conventional fire hydrant device 100 shown in FIG. 16. Furthermore, as shown in FIG. 9(B), the space required to open and close the hydrant door 48 (the area through which the hydrant door 48 passes) is a semicircular area in plan view, with the torque hinge 22 at the center and the width W1 of the central opening 1410 in which the hydrant door 48 is disposed as the radius, and can be significantly reduced compared to the conventional fire hydrant device 100 shown in FIG. 16. Furthermore, because the hydrant door 48 is disposed in the upper half of the central opening 1410, it is possible to further suppress or prevent the opening of the hydrant door from being obstructed by objects placed near the hydrant device, and it is also possible to further reduce the weight of the hydrant door.

[0116] Furthermore, a shape-retaining hose 32 is stored in a hose storage section inside the housing 12 so that it can be pulled out freely, and as shown in Figure 9(A), a water-discharge nozzle 34 is connected to the tip of the shape-retaining hose 32, and the water-discharge nozzle 34 is detachably held in a nozzle holder 36 provided on the back side of the hydrant door 48, and by opening the hydrant door 48, it is possible to operate the hydrant valve 38 provided on the back side inside the housing 12.

[0117] Therefore, when a user opens the fire hydrant door 48, the user can take out the water discharge nozzle 34 that appears in front of the user and operate the fire hydrant valve 38 to supply fire water to the shape-retaining hose 32 and discharge water from the water discharge nozzle 34.

[0118] As shown in FIG. 10, hose guides 42 are erected on the front side of the hose storage section 30 at positions near the boundary between the central opening 1410 and the side openings 1412 and 1414, and hose guides 45 are provided in the left-right direction between the hose guides 42 so that the upper half is exposed from the lower edge of the opening when the hydrant door 48 is opened.

[0119] The hose outlet is formed by the upper frame of the housing 12 of the two hose guides 42 and 45, and cylindrical or columnar support members are used as the hose guides 42 and 45, for example, which reduces frictional resistance when the hose guides 42 and 45 slide against each other as the shape-retaining hose 32 is pulled out, making it possible to pull out the shape-retaining hose 32 with little force and suppressing wear on the shape-retaining hose 32.

[0120] In addition, in the third embodiment, in order to make it easy to open the hydrant door 48 and rewind the shape-retaining hose 32 that has been pulled out into the hose storage section 30 inside the housing 12, the structure allows the exterior panel 18 to be opened when the shape-retaining hose 32 is rewound.

[0121] 11 , exterior plate 18 is pivotally supported by hinges 52 at the lower left and right side edges relative to the frame of housing 12 so that it can rotate freely around its lower edge, and is fixed in a position that closes front opening 14 by passing screws 56 through screw holes 54 formed in the upper and center of each side edge and through screw holes formed in the frame of housing 12 that correspond to screw holes 54. In addition, a chain 58 is provided between the upper back surface of exterior plate 18 and the front of the top surface inside housing 12.

[0122] Therefore, when the pulled-out shape-retaining hose 32 is to be rewound into the hose storage section 30 inside the housing 12, after draining the water from the shape-retaining hose 32, the screws 56 are removed to release the outer plate 18 from the housing 12, and the outer plate 18 is rotated around its lower edge to the fully open position determined by the length of the chain 58, and the chain 58 holds the outer plate 18 in the fully open position.By utilizing the opening formed by opening the outer plate 18, the shape-retaining hose 32 can be easily wound in an inclined overlapping manner onto the inclined plate 40 of the hose storage section 30.

[0123] [d. Fourth embodiment of the fire hydrant device] Next, a fourth embodiment of the fire hydrant device will be described. The fourth embodiment of the fire hydrant device is characterized by a downward-opening hydrant door provided in the upper half of the central opening. In this description, reference will be made to FIG. 12, which shows the fourth embodiment of the fire hydrant device, and FIG. 13, which shows the fire hydrant device of FIG. 12 with the hydrant door open. Note that FIGS. 12(A) and 13(A) show the right side, and FIGS. 12(B) and 13(B) show the front (anterior). Furthermore, for components that are assigned the same reference numerals as in the first embodiment and whose description is omitted in the fourth embodiment, the contents described in the first embodiment are basically to be referenced.

[0124] As shown in FIG. 12(B), in the fire hydrant device 10 of the fourth embodiment, similar to the third embodiment, a front opening 14 is formed on the front surface of the housing 12 below the emergency call door 24, which is virtually divided into a central opening 1410 and side openings 1412, 1414, and a fire hydrant door 48 is arranged in the upper half of the central opening 1410, and exterior panels 18 are arranged on the lower half of the central opening 1410 and the side openings 1412, 1414.

[0125] Also, as in the third embodiment, the width of the fire hydrant door 48 (= width of the central opening 1410) is W1 (= 375 mm), the vertical width is H1 (= 450 mm), which is half the vertical width H0 (= 900 mm) of the front opening 14, and the width of the side openings 1412, 1414 is W2 (= 187.5 mm).

[0126] The hydrant door 48 is pivotally supported on the exterior panel 18 by torque hinges 22 provided on both the left and right sides of the lower edge, allowing it to be freely opened downward. By operating the door opening / closing handle 50 provided on the top of the hydrant door 48, the state in which the door is held in the closed position is released, and the door is rotated approximately 180° to the fully open position as shown in Figure 13, allowing it to be opened.

[0127] For this reason, the open fire hydrant door 48 does not protrude in the vertical or horizontal directions from the housing 12, and the space required to open and close the fire hydrant door 48 (the area through which the fire hydrant door 48 passes) is a semicircular area with the torque hinge 22 as the axis and the vertical width H1 of the fire hydrant door 48 as the radius in a side view, as shown in Fig. 13(B), which can be significantly reduced compared to the conventional fire hydrant device 100 shown in Fig. 16. Furthermore, because the fire hydrant door 48 is arranged in the upper half of the central opening 1410, it is possible to further suppress or prevent the opening of the fire hydrant door from being obstructed by objects placed near the fire hydrant device, and it is also possible to further reduce the weight of the fire hydrant door.

[0128] Furthermore, a shape-retaining hose 32 is stored in a hose storage section inside the housing 12 so as to be freely retractable, and as shown in Figure 13(B), a water discharge nozzle 34 is connected to the tip of the shape-retaining hose 32, and the water discharge nozzle 34 is detachably held in a nozzle holder 36 provided on the back side of the hydrant door 48, and opening the hydrant door 48 makes it possible to operate the hydrant valve 38 provided on the back side inside the housing 12. Note that it is desirable to shift the nozzle holder 36 to an offset position so that the hydrant valve 38 and the water discharge nozzle 34 held in the nozzle holder 34 do not overlap when the hydrant door 48 is closed.

[0129] Therefore, when a user opens the fire hydrant door 48, the user can take out the water discharge nozzle 34 that appears in front of the user and operate the fire hydrant valve 38 to supply fire water to the shape-retaining hose 32 and discharge water from the water discharge nozzle 34.

[0130] Furthermore, similar to the third embodiment shown in FIG. 10, hose guides 42 are erected on the front side of the hose storage section 30 at positions near the boundary between the central opening 1410 and the side openings 1412, 1414, and hose guides 45 are provided in the left-right direction between the hose guides 42 so that the upper half is exposed from the lower edge of the opening when the hydrant door 48 is opened.

[0131] 11, the exterior plate 18 is pivotally supported by hinges 52 at the lower portions of both left and right side edges relative to the frame of the housing 12, and is fixed in a position that closes the front opening 14 by passing screws 56 through screw holes 54 formed at the upper and center of both left and right side edges and through screw holes formed in the frame of the housing 12 that correspond to the screw holes 54, and a chain 58 is provided between the upper back surface of the exterior plate 18 and the front of the top surface inside the housing 12.

[0132] [e. Fifth embodiment of the fire hydrant device] Next, a fifth embodiment of the fire hydrant device will be described. The fifth embodiment of the fire hydrant device is characterized by the provision of a downward-opening fire hydrant door in the upper half of the front opening. In this description, reference will be made to Fig. 14, which shows the fifth embodiment of the fire hydrant device, and Fig. 15, which shows the fire hydrant device of Fig. 14 with the hydrant door open. Note that Fig. 15(A) shows the right side, and Fig. 15(B) shows the front (front). Furthermore, for components that are assigned the same reference numerals as in the first embodiment and whose description is omitted in the fifth embodiment, the contents described in the first embodiment are basically to be referenced.

[0133] As shown in FIG. 14, the fire hydrant device 10 of the fifth embodiment has a front opening 14 formed on the front surface of the housing 12 below the emergency notification door 24, a fire hydrant door 60 arranged in the upper half of the front opening 14, and an exterior panel 18 arranged in the lower half of the front opening 14.

[0134] The width of the fire hydrant door 60 is the width W0 (= 750 mm) of the front opening 14, and the vertical width is H1 (= 450 mm), which is half the vertical width H0 (= 900 mm) of the front opening 14, as in the third embodiment.

[0135] The hydrant door 60 is pivotally supported on the exterior panel 18 by torque hinges 22 provided on both the left and right sides of the lower edge, allowing it to be freely opened downward. By operating the door opening / closing handle 50 provided on the top of the hydrant door 60, the state in which it is held in the closed position is released, and it rotates approximately 180° to the fully open position as shown in Figure 15 and is opened.

[0136] As a result, the open fire hydrant door 60 does not protrude in the vertical or horizontal directions from the housing 12, and the space required to open and close the fire hydrant door 60 (the area through which the fire hydrant door 60 passes) is a semicircular area in side view, as shown in Figure 15 (A), with the torque hinge 22 as the axis and the vertical width H1 of the fire hydrant door 48 as the radius, which can be significantly reduced compared to the conventional fire hydrant device 100 shown in Figure 16.

[0137] In addition, a shape-retaining hose 32 is stored in a hose storage section inside the housing 12 so that it can be pulled out freely, and as shown in Figure 15 (B), a water-discharge nozzle 34 is connected to the tip of the shape-retaining hose 32, and the water-discharge nozzle 34 is detachably held in a nozzle holder 36 provided on the back side of the hydrant door 60, and by opening the hydrant door 60, it is possible to operate the hydrant valve 38 provided on the back side inside the housing 12.

[0138] Therefore, when a user opens the fire hydrant door 60, the user can take out the water discharge nozzle 34 that appears in front of the user and operate the fire hydrant valve 38 to supply fire water to the shape-retaining hose 32 and discharge water from the water discharge nozzle 34.

[0139] In addition, hose guides 42 are erected at predetermined intervals in the hose storage section inside the housing 12, and hose guides 45 are provided in the left-right direction between the hose guides 42 so that the upper half is exposed from the lower edge of the opening when the fire hydrant door 48 is opened.

[0140] Furthermore, because opening the hydrant door 60 creates a sufficiently large opening in the upper half of the front opening 14, the structure that enables the exterior panel 18 shown in the third embodiment to be opened is not necessary, and it is possible to easily insert one's hand through the opening formed by the downward-opening hydrant door 60 and rewind the shape-retaining hose 32 into the hose storage section 30.

[0141] [f. Modifications of the present invention] Modifications of the fire hydrant device according to the present invention will be described. In addition to the above-described embodiment, the fire hydrant device of the present invention includes the following modifications.
