(Fire hydrant section)
The fire hydrant section 110 is a part forming a housing structure above the road fire hydrant 100. Inside the fire hydrant section 110, various control devices, operating devices, etc. necessary for extinguishing a fire using the road fire hydrant 100 are housed. Specifically, the fire hydrant part 110 houses a fire hydrant lever 101, a lever guide 103, and a nozzle fixing part 107 for fixing the nozzle 105.

The fire hydrant section 110 has a casing structure that is sealed to the extent that foreign objects (dust, small animals, or large amounts of moisture such as water leakage) can be suppressed from entering the interior, in order to protect the equipment stored therein. ing. On the other hand, a part of the housing structure of the fire hydrant section 110 can be opened and closed in order for the user to take out the nozzle 105 housed inside or operate the equipment during fire extinguishing work.

Specifically, as shown in FIGS. 3 and 4, the fire hydrant section 110 includes a fire hydrant door 111, a front hose door 113, and a side hose door 115. The fire hydrant door 111 is a door provided near the center of the fire hydrant part 110 in the width direction (X direction in FIG. 3) on the observer passageway PW side of the fire hydrant part 110. For example, the fire hydrant door 111 is pivotally supported by a pair of hinges 111a, so that the fire hydrant door 111 can be opened and closed toward the lifeguard passageway PW. The fire hydrant door 111 is opened, for example, at least when the hose 109 is taken out. That is, as shown in FIG. 3, by opening the fire hydrant door 111, it becomes possible to take out the nozzle 105 and the hose 109 from the inside of the fire hydrant section 110 to the lifeguard passage PW side.

(Front hose door)
The front hose door 113 is a door provided at the lower part of the fire hydrant section 110 on the observer passage PW side of the fire hydrant section 110. That is, the front hose door 113 is provided below the fire hydrant door 111. The front hose door 113 has a width W that is equal to the width of the fire hydrant section 110 (the length in the X direction in FIG. 3). Here, the width equal to the width of the fire hydrant part 110 is not limited to the case where the width of the front hose door 113 completely matches the width of the fire hydrant part 110, but also the gap for opening and closing the door, dimensional error, etc. The purpose is to allow differences caused by such factors. Further, the front hose door 113 has a height h1 that is greater than or equal to the diameter R of the hose 109. As an example, the diameter R of the hose 109 is about 40 mm. Furthermore, as an example, the height h1 of the front hose door 113 is approximately 60 to 70 mm.

Further, as shown in FIGS. 5A and 5B, the front hose door 113 covers the lifeguard passage PW side of the fire hydrant section 110, and also covers a part of the side hose door 115 from the outside. Specifically, the front hose door 113 has a main body part 113a and side parts 113b bent from both ends of the main body part 113a in the longitudinal direction (X direction in FIG. 5B).

The main body portion 113a covers a portion of the fire hydrant portion 110 below the fire hydrant door 111. The side surface portion 113b covers a part of the side hose door 115 from the outside, as shown in FIGS. 5A and 5B. That is, the side surface portion 113b faces the end of the side hose door 115 on the observer passage PW side when the front hose door 113 is closed. The width of the side surface portion 113b (the distance in the Y direction in FIG. 5B) is shorter than the width of the side hose door 115 (the distance in the Y direction in FIG. 5B).

When fire extinguishing work is not performed using the road fire hydrant 100, the front hose door 113 is attached and fixed to the lower end of the fire hydrant door 111 by a fixed magnet 113c provided at the upper end. On the other hand, during fire extinguishing work, the front hose door 113 is opened toward the outside of the fire hydrant section 110 as shown in FIGS. 6A and 6B by being rotated by a rotating shaft provided at the lower end. Specifically, as shown in FIG. 3, the front hose door 113 is pivotally supported via a pair of hinges 113d.

When the front hose door 113 is opened, the fire hydrant door 111 and the front hose door 113 can have a continuous opening (corresponding to the first opening 131 described below) when opened, although details will be described later. The inside and outside of the casing of the fire hydrant section 110 are communicated through this opening, and the hose 109 is drawn out to the outside of the road fire hydrant 100.

(side hose door)
As shown in FIGS. 3 and 4, the side hose door 115 is a door provided on the side wall 117 of the fire hydrant section 110 (the wall facing in the X direction in FIG. 4) and at the bottom of the fire hydrant section 110. be. The side hose door 115 is provided at the same position as the front hose door 113 in the vertical direction (Z direction in FIG. 4). Further, the side hose door 115 has a height h2 that is greater than or equal to the diameter R of the hose 109. As an example, the height h2 of the side hose door 115 is approximately 60 to 70 mm.

The side hose door 115 is opened toward the outside of the fire hydrant section 110 by rotating around a rotation shaft provided at the upper end. Specifically, as shown in FIG. 4, the side hose door 115 is pivotally supported at its upper end via a hinge 115a. On the other hand, when fire extinguishing work is not performed using the road fire hydrant 100, the side hose door 115 is biased by an unillustrated biasing member (for example, a torsion spring, etc.), so that the side hose door 115 is closed. The state is maintained.

When the side hose door 115 is opened, the front hose door 113 and the side hose door 115 can have a continuous opening (corresponding to a second opening 132 described below) when opened, although details will be described later. . The inside and outside of the casing of the fire hydrant section 110 are communicated through this opening, and the hose 109 is drawn out to the outside of the road fire hydrant 100.

(Hose storage part)
As shown in FIGS. 3 and 4, the hose storage section 120 is a portion having a housing structure capable of storing the hose 109 connected to the nozzle 105. The hose storage section 120 is provided below the fire hydrant section 110, and the hose storage section 120 and the fire hydrant section 110 communicate with each other inside the road fire hydrant 100. The hose storage section 120 has a hose cage 121 that is a pair of rod-shaped members. The hose cage 121 has its longitudinal direction extending along the width direction of the fire hydrant 100 (X direction in FIG. 3). Further, the hose cages 121, which are a pair of rod-shaped members, are arranged apart from each other in the vertical direction (Z direction in FIG. 3). The hose 109 wound into an oblong shape is held by the hose cage 121 within the housing structure of the hose storage section 120, as shown in FIG.

A distal end side 109a of the hose 109 (an end side to which the nozzle 105 is attached) passes between a pair of hose cages 121, and is disposed toward the fire hydrant section 110 from the hose storage section 120. When the road fire hydrant 100 is used, the hose 109 is pulled out from the hose storage part 120 while passing between the hose cages 121. The rear end side 109b of the hose 109 (the end side where the nozzle 105 is not attached) is connected to a fire extinguishing water supply source (not shown) provided outside the road fire hydrant 100 via a pipe connection metal 109c. has been done.

Further, the hose storage section 120 is provided closer to the observer path PW than the front hose door 113. Specifically, as shown in FIG. 4, when the road fire hydrant 100 is viewed from the side (viewed in the X direction in FIG. 4), the wound hose 109 is placed closer to the front hose door 113 by the hose cage 121. It is held on the lifeguard passage PW side. The schematic configuration of the road fire hydrant 100 according to the present embodiment has been described above.

<3. How to use road fire hydrants>
Next, a method of using the road fire hydrant 100 according to this embodiment will be described with reference to FIGS. 7 to 19. 7 to 19 are diagrams showing usage examples of the road fire hydrant 100 according to the present embodiment.

First, with reference to FIGS. 7 to 15, a case will be described in which the hose 109 is pulled out to the left of the road fire hydrant 100 when viewed from the lifeguard passageway PW side. First, as shown in FIG. 7, the fire hydrant door 111 is operated by the user to open the road fire hydrant 100 with the fire hydrant door 111 closed. Specifically, the grip part 111b provided on the fire hydrant door 111 is operated by the user to release the fixation of the fire hydrant door 111, and the fire hydrant door 111 is opened to the lifeguard passageway PW side.

Thereafter, as shown in FIGS. 8 and 9, the nozzle 105 is removed from the nozzle fixing part 107 and taken out from the fire hydrant part 110. Further, the fire hydrant lever 101 is operated to supply fire extinguishing water into the hose 109. As the nozzle 105 is removed, the distal end 109a of the hose 109 connected to the nozzle 105 is also removed from the fire hydrant section 110 toward the lifeguard passageway PW.

As the hose 109 is taken out to the observer path PW side, the hose 109 comes into contact with the front hose door 113, thereby opening the front hose door 113. Specifically, as shown in FIG. 9, the front hose door 113 is opened to the outside of the fire hydrant section 110 around the rotation axis of the hinge 113d at the lower end. In particular, when fire extinguishing water is supplied into the hose 109, the weight of the hose 109 increases not only by its own weight but also by the extinguishing water. As a result, the front hose door 113 comes into contact with the hose 109 and becomes easier to open. The opened front hose door 113 comes into contact with the upper surface of the lifeguard passageway PW, and is in a state of being bridged between the road fire hydrant 100 and the upper face of the lifeguard passageway PW.

By opening the front hose door 113, a continuous first opening 131 is formed when the fire hydrant door 111 and the front hose door 113 are opened, as shown in FIG. The first opening 131 is an opening that communicates the fire hydrant section 110 with the outside. Through the first opening 131, the hose 109 is taken out from the fire hydrant section 110 toward the lifeguard passage PW side.

Thereafter, as shown in FIGS. 10 and 11, the nozzle 105 and the hose 109 are further pulled out to the left with respect to the road fire hydrant 100. That is, when the user moves along the lifeguard path PW while holding the nozzle 105, the hose 109 is pulled out from the road fire hydrant 100 together with the nozzle 105. At this time, since the front hose door 113 is open, the hose 109 can easily come out to the observer passageway PW side.

Furthermore, as shown in FIGS. 12 and 13, the hose 109 continues to be pulled out. As a result, a portion of the hose 109 gradually moves downward due to its weight. At this time, the first opening 131 is formed by opening the front hose door 113 together with the fire hydrant door 111, so even if a portion of the hose 109 descends, there will be no problem in drawing out the hose 109. . That is, the opening formed by opening the fire hydrant door 111 and the opening formed by opening the front hose door 113 are continuous, so that the hose 109 is placed at a relatively high position at the beginning of pulling out (from the height of the front hose door 113). The movement from a relatively high position (near the upper surface of the lifeguard passageway PW) to a relatively low position (near the top surface of the observer passageway PW) after being pulled out to some extent is performed smoothly. As a result, the movement of the hose 109 is not hindered, so that the hose 109 is prevented from getting caught, and less force is required for pulling out the hose 109, so that there is less trouble in pulling out the hose 109.

Furthermore, as shown in FIGS. 14 and 15, if the hose 109 continues to be pulled out, a portion of the hose 109 will be pulled out while being supported by the upper surface of the lifeguard passageway PW. Furthermore, as a result of the longer distance that the hose 109 is pulled out, the direction in which the hose 109 is pulled out approaches the direction along the width direction of the road fire hydrant 100 (the X direction in FIG. 14). Therefore, as the hose 109 is pulled out, the side hose door 115 and the hose 109 come into contact. Although the side hose door 115 is biased to remain closed by a biasing member (not shown) such as a torsion spring, as the hose 109 moves, the side hose door 115 opens upward as shown in FIG. It is pushed up and released.

In particular, assuming that the width of the lifeguard passageway PW (distance in the Y direction in FIG. 15) is approximately 70 cm and the hose 109 is pulled out along the lifeguard passageway PW for approximately several tens of meters (for example, 30m), the hose 109 is pulled out along the almost lateral direction (X direction in FIG. 14) with respect to the road fire hydrant 100.

When the side hose door 115 is opened, a continuous second opening 132 is formed when the front hose door 113 and the side hose door 115 are opened, as shown in FIGS. 14 and 15. The second opening 132 is an opening that communicates the fire hydrant section 110 with the outside. The hose 109 is taken out to the side of the road fire hydrant 100 through the second opening 132 .

Since the hose 109 is pulled out through the second opening 132, even if the hose 109 is pulled out while contacting the upper surface of the lifeguard passageway PW, the hose 109 is less likely to be hindered in being pulled out. That is, the opening formed by opening the front hose door 113 and the opening formed by opening the side hose door 115 are continuous, so that the hose 109 can be moved in the width direction of the road fire hydrant 100 (X direction in FIG. 14). Since the road fire hydrant 100 is pulled out in the direction along the road, the movement of the road fire hydrant 100 from the front side to the side side is not hindered. Further, as shown in FIG. 15, the route taken by the hose 109 in the road fire hydrant 100 is a straight line from the hose storage section 120 to the side hose door 115. Therefore, resistance to pulling out due to bending is less likely to occur. As a result, it is difficult for the hose 109 to be pulled out without difficulty.

Fire extinguishing water is supplied to the location of the fire via the pulled out nozzle 105 and hose 109, and fire extinguishing activities are carried out.

Next, the case where the hose 109 is pulled out to the right with respect to the road fire hydrant 100 will be described with reference to FIGS. 16 to 19. It should be noted that a description of contents common to the above-described case where the hose 109 is pulled out to the left with respect to the road fire hydrant 100 may be omitted.

First, as shown in FIGS. 16 and 17, after the nozzle 105 and the hose 109 are pulled out, the hose 109 comes into contact with the front hose door 113, thereby opening the front hose door 113. As a result, when the fire hydrant door 111 and the front hose door 113 are opened, a continuous first opening 131 is formed. Through the first opening 131, the hose 109 is taken out from inside the fire hydrant section 110 toward the lifeguard passageway PW.

Furthermore, as shown in FIGS. 18 and 19, if the hose 109 continues to be pulled out, a portion of the hose 109 will be pulled out while being supported by the upper surface of the lifeguard passageway PW. As the hose 109 is pulled out, the side hose door 115 and the hose 109 come into contact. Although the side hose door 115 is biased by a biasing member (not shown), it is pushed upward and opened as the hose 109 moves. When the side hose door 115 is opened, a continuous second opening 132 is formed when the front hose door 113 and the side hose door 115 are opened. The hose 109 is taken out to the right side of the road fire hydrant 100 through the second opening 132 . Fire extinguishing water is supplied to the location of the fire via the pulled out nozzle 105 and hose 109, and fire extinguishing activities are carried out. The method of using the road fire hydrant 100 according to the present embodiment has been described above.

(effect)
According to this embodiment, after the hose 109 is taken out from the fire hydrant door 111, the front hose door 113 comes into contact with the hose 109 and is opened, and the hose 109 passes through the first opening 131 to the lifeguard passage PW side. taken out. Furthermore, if the hose 109 continues to be pulled out to the side of the fire hydrant section 110, the side hose door 115 will be opened and the hose 109 will be pulled out through the second opening 132. Thereby, it becomes possible to suppress the curvature of the hose 109 within the road fire hydrant 100, and it becomes easy to take out the hose 109 to the side of the fire hydrant section 110.

In other words, assuming that the hose 109 is taken out only from the opening that occurs when the fire hydrant door 111 is opened, the hose 109 will be pulled out from the hose storage section 120 to the opening of the fire hydrant door 111 while curving greatly. That is, inside the road fire hydrant 100, after the hose 109 is once pulled out to the road RW, it passes through the opening of the fire hydrant door 111 while drawing a curved path in a side view of the road fire hydrant 100. Furthermore, even after the hose 109 comes out of the road fire hydrant 100, the distal end 109a of the hose 109 is pulled out along the lifeguard passage PW in the lateral direction of the road fire hydrant 100, so that the hose 109 is bent. do. In this way, when the hose 109 is taken out only through the opening that occurs when the fire hydrant door 100 is opened, the hose 109 is bent tightly (the radius of curvature is small), and there are many curved parts, resulting in a large resistance when being pulled out. Become. Furthermore, since the hose 109 is pulled out from the opening of the fire hydrant door 100 of the fire hydrant section 100 to the side of the road fire hydrant 100, it becomes easily caught on the edge of the opening of the fire hydrant door 111.

Therefore, since the present embodiment has the above configuration, it is possible to suppress the bending of the hose 109 within the road fire hydrant 100, and the hose 109 can be taken out to the side of the fire hydrant part 110. becomes easier. In particular, the route taken by the hose 109 within the road fire hydrant 100 is a straight line from the hose storage section 120 to the side hose door 115. Also, when going out of the road fire hydrant 100, the hose is pulled out straight from the side hose door 115 to the side of the road fire hydrant 100. In this way, the ease with which the hose 109 can be taken out to the side of the road fire hydrant 100 can be improved.

Further, according to this embodiment, the front hose door 113 is configured to cover the side hose door 115 from the outside. This prevents the side hose door 115 from being opened inadvertently. Furthermore, since the side hose door 115 is further covered by the front hose door 113, entry of foreign matter into the road fire hydrant 100 is further suppressed.

Further, according to the present embodiment, the side hose door 115 is opened toward the outside of the fire hydrant section 110 by rotating around the rotation shaft provided at the upper end. Thereby, it becomes easy to open by contact with the hose 109, and it is possible to suppress the intrusion of foreign substances such as water flowing through the side wall 117 of the fire hydrant section 110. Furthermore, since it has a simple structure that rotates around a rotating shaft, malfunctions due to dust etc. are less likely to occur compared to opening and closing the door using a slide rail structure.

Further, according to the present embodiment, the front hose door 113 is opened toward the outside of the fire hydrant section 110 by rotating around the rotation shaft provided at the lower end. This facilitates opening of the front hose door 113 when the hose 109 is pulled out from the fire hydrant door 111. In addition, since it has a simple configuration in which it rotates by a rotating shaft, malfunctions due to adhesion of dust and the like are less likely to occur, compared to opening and closing a door using a slide rail structure.

In addition, since the front hose door 113 or the side hose door 115 is configured to be opened by rotating around the rotation axis, the road fire hydrant 100 and the front hose door 113 or the side hose door 115 remain open even after opening. They are all one. Therefore, parts of the road fire hydrant 100 are prevented from scattering onto the road RW or the lifeguard path PW.

Further, according to the present embodiment, the hose storage section 120 is provided closer to the observer path PW than the front hose door 113 is. If the hose storage section 120 is located closer to the lifeguard passageway PW than the front hose door 113, it will be more likely to curve when pulled out; By being pulled out to the side, the path of the hose 109 becomes straight, and bending of the hose 109 within the road fire hydrant 100 is suppressed. As a result, the ease with which the hose 109 can be taken out to the side of the road fire hydrant 100 can be improved.

Further, according to this embodiment, the side hose doors 115 are provided on both side walls 117 of the fire hydrant section 110, respectively. As a result, bending of the hose 109 within the road fire hydrant 100 is suppressed when the hose 109 is pulled out either to the left or to the right with respect to the road fire hydrant 100 when viewed from the lifeguard passageway PW side. . The road fire hydrant 100 according to one embodiment of the present invention has been described above.

Although preferred embodiments of the present invention have been described above in detail with reference to the accompanying drawings, the present invention is not limited to such examples. It is clear that a person with ordinary knowledge in the technical field to which the present invention pertains can come up with various modifications or applications within the scope of the technical idea stated in the claims. It is understood that these also naturally fall within the technical scope of the present invention.

For example, in the above embodiment, an example was shown in which the side hose doors 115 were provided on both side walls 117 of the fire hydrant section 110, but the present invention is not limited to such an example. For example, the side hose door 115 may be provided only on one side wall 117 of the fire hydrant section 110.

Further, in the above embodiment, an example was shown in which the front hose door 113 is made of a single plate-like member extending in the width direction of the fire hydrant section 110, but the present invention is not limited to such an example. For example, the front hose door 113 may be divided into a plurality of plate-like members in the width direction of the fire hydrant section 110, and each plate-like member may be opened independently.
