[0015] In addition, in this specification and drawings, when multiple identical functional configurations are to be described separately, an alphabet may be added to the end of the reference numeral. On the other hand, when there is no need to distinguish between multiple identical functional configurations, the alphabet may be omitted and a description common to all multiple identical functional configurations may be given.

[0016] In addition, in the drawings, even if a component is assigned a symbol in another drawing, if the component can be identified by its positional relationship with other components, the symbol may be omitted in order to prioritize visibility of the drawing. <1. Embodiment> <<1.1. Configuration example of road fire hydrant 10>> First, a configuration example of a roadway fire hydrant 10 according to one embodiment of the present invention will be described with reference to Figures 1 to 4. The roadway fire hydrant 10 according to this embodiment includes an upper door 110 and a side door 120.

[0017] Figures 1 and 3 are diagrams mainly for explaining the external structure of the roadway fire hydrant 10 according to this embodiment. Figure 1 mainly shows the external structure of the roadway fire hydrant 10 when the upper door 110 and the side door 120 are in a fully closed state. On the other hand, Figure 3 mainly shows the external structure of the roadway fire hydrant 10 when the upper door 110 and the side door 120 are in a fully open state.

[0018] Figures 2 and 4 are diagrams mainly for explaining the internal structure of the roadway fire hydrant 10 according to this embodiment. Figure 2 mainly shows the internal structure of the roadway fire hydrant 10 when the upper door 110 and the side door 120 are in a fully closed state. On the other hand, Figure 4 mainly shows the internal structure of the roadway fire hydrant 10 when the upper door 110 and the side door 120 are in a fully open state.

[0019] 1 to 4 show a side view of the road fire hydrant 10 according to this embodiment in the short side direction. As shown in the side view of the short side, the road fire hydrant 10 according to this embodiment is installed in a tunnel or the like between a roadway RW and a passage PW parallel to the roadway RW.

[0020] The passageway PW is provided for people to pass through and perform work. The work includes, for example, firefighting, maintenance, etc. The passageway includes not only passage for carrying out the work but also passage for evacuation.

[0021] 1 to 4 show top views of the road fire hydrant 10 according to this embodiment, and the left side of the bottom rows of FIGS. 1 to 4 show longitudinal side views of the road fire hydrant 10 according to this embodiment.

[0022] As shown in FIGS. 2 and 4, the road hydrant 10 according to this embodiment includes a storage section 190 inside a housing 180, the storage section 190 comprising an upper storage section 192 and a lower storage section 194.

[0023] The upper storage section 192 may be, for example, a space above the passage PW (upper surface) within the space of the storage section 190. On the other hand, the lower storage section 194 may be a space below the passage PW (upper surface) within the space of the storage section 190.

[0024] The lower storage section 194 stores, for example, the hose 150. On the other hand, the upper storage section 192 stores the hydrant nozzle 160 connected to the hose 150 and the hydrant lever 170.

[0025] In addition to the hydrant nozzle 160 and the hydrant lever 170, the upper storage section 192 may also store electrical components for operating a red indicator light, push button, response lamp, etc., which are located outside the housing 180.

[0026] Next, the upper door 110 and the side door 120 provided on the road fire hydrant 10 according to this embodiment will be described.

[0027] The upper door 110 according to this embodiment is used to open and close the opening above the storage section 190. More specifically, the upper door 110 according to this embodiment is provided so as to be able to open and close the upper storage section 192 and the lower storage section 194 simultaneously.

[0028] A user performing firefighting work or a maintenance worker performing maintenance work on the road fire hydrant 10 can simultaneously open and close the upper storage section 192 and the lower storage section 194 by grasping the handle 115 and opening and closing the upper door 110.

[0029] Therefore, users and maintenance personnel performing fire extinguishing work can easily access the fire hydrant nozzle 160 stored in the upper storage section 192 whether from the roadway RW side or the passageway PW side, and can easily pull out the hose 150 stored in the lower storage section 194.

[0030] On the other hand, the side door 120 according to this embodiment is used to open and close the opening on the side of the lower storage section 194 on the roadway RW side.

[0031] A user performing firefighting work or a maintenance worker performing maintenance work on the road hydrant 10 can roll up the hose 150 and store it from the opening on the side of the lower storage section 194 on the roadway RW side, which is opened when the side door 120 is opened.

[0032] As shown in Figures 3 and 4, the upper door 110 and the side door 120 according to this embodiment do not protrude toward either the roadway RW or the aisle PW even when fully open. Furthermore, as will be described in detail later, one of the features of the upper door 110 and the side door 120 according to this embodiment is that they do not protrude toward either the roadway RW or the aisle PW at any stage during opening or closing. This feature does not interfere with passage or work on the roadway RW or the aisle PW, improving safety.

[0033] Furthermore, one of the features of the side door 120 according to this embodiment is that it opens and closes simultaneously with the upper door 110 in conjunction with the opening and closing operation of the upper door 110. This feature improves convenience and also allows opening and closing operations from the aisle PW side, improving safety.

[0034] Hereinafter, a detailed description will be given of the configuration that realizes simultaneous opening and closing of the upper door 110 and the side door 120 according to this embodiment. Note that in Figs. 1 to 4, the illustration of this configuration is omitted in order to prioritize visibility of the drawings.

[0035] Fig. 5 shows a side view of the roadway hydrant 10 as seen from the roadway RW side when the upper door 110 and the side door 120 are in a fully closed state. Note that in Fig. 5 and subsequent figures, the handle 115 may be omitted. Also, in Fig. 5 and subsequent figures, a two-dot chain line may be used as an omission line.

[0036] As shown in Figure 5, the road hydrant 10 of this embodiment is arranged on the side of the housing 180 facing the roadway RW, and is equipped with a first guide member 210 having a housing connection portion 213 (also referred to as the first housing connection portion) connected to the housing 180 and a first upper door connection portion 211 connected to the upper door 110.

[0037] FIG. 5 illustrates an example in which the road hydrant 10 according to this embodiment includes two first guide members 210A and 210B.

[0038] In addition, the road fire hydrant 10 of this embodiment is arranged on the side of the housing 180 facing the roadway RW, and is equipped with a second guide member 220 having a housing connection portion 223 (also referred to as the second housing connection portion) connected to the housing 180 and a side door connection portion 222 connected to the side door 120.

[0039] FIG. 5 illustrates an example in which the road hydrant 10 according to this embodiment includes two second guide members 220A and 220B.

[0040] Here, one of the features of the side door 120 of this embodiment is that it opens and closes by rotating the housing connection part 223 due to the force transmitted from the housing connection part 213, which rotates as the upper door 110 opens and closes.

[0041] FIG. 6 is a diagram showing an example of the configuration of the first guide member 210 and the second guide member 220 according to this embodiment.

[0042] For example, as shown in FIG. 6, the housing connection portion 213 of the first guide member 210 may include a gear 214 , and the housing connection portion 223 of the second guide member 220 may include a gear 224 that mates with the gear 214 .

[0043] With this configuration, as the upper door 110 opens and closes, the first upper door connection portion 211 of the first guide member 210 rotates around the housing connection portion 213 as an axis, transmitting force from gear 214 to gear 224, and the side door connection portion 222 of the second guide member 220 rotates around the housing connection portion 223 as an axis, allowing the side door 120 to rotate in the opposite direction to the upper door 110.

[0044] The housing connection portion 213 of the first guide member 210 and the housing connection portion 223 of the second guide member 220 may be rotatably connected to the housing 180 by a housing fixing member 215 and a housing fixing member 225, respectively.

[0045] The first upper door connecting portion 211 of the first guide member 210 may be rotatably connected to the upper door 110 by an upper door fixing member 216 .

[0046] The side door connecting portion 222 of the second guide member 220 may be rotatably connected to the side door 120 by a side door fixing member 227 .

[0047] Figure 7 is a diagram for explaining the housing connection portion 213 and the first upper door connection portion 211 of the first guide member 210 in this embodiment, and the housing connection portion 223 and the side door connection portion 222 of the second guide member 220.

[0048] Figure 7 shows a side view of the housing connection part 213, the first upper door connection part 211, the housing connection part 223, and the side door connection part 222 when the first guide member 210 and the second guide member 220 are installed on the road fire hydrant 10.

[0049] The housing connection portion 213 of the first guide member 210 may be realized, for example, by fixing a gear 214 and a housing fixing member 215 that passes through a hole formed at one end of the first guide member 210 to the housing 180, as shown in the upper left side of Figure 7.

[0050] Similarly, the housing connection portion 223 of the second guide member 220 may be realized, for example, by fixing a gear 224 and a housing fixing member 225 that passes through a hole formed at one end of the second guide member 220 to the housing 180, as shown in the lower left side of Figure 7.

[0051] In addition, the first upper door connection portion 211 of the first guide member 210 may be realized, for example, by passing an upper door fixing member 216 through a hole formed at the other end of the first guide member 210 and a fixed portion 117 formed on the upper door 110 and fixing them, as shown in the upper right side of Figure 7.

[0052] Similarly, the side door connection portion 222 of the second guide member 220 may be realized, for example, by passing a side door fixing member 227 through a hole formed at the other end of the second guide member 220 and a hole formed in the side door 120, as shown in the lower right side of Figure 7.

[0053] The above describes exemplary configurations of the first guide member 210 and the second guide member 220 according to this embodiment. However, the configurations described above are merely examples, and the configurations of the first guide member 210 and the second guide member 220 according to this embodiment are not limited to these examples.

[0054] For example, in the above description, the case has been described in which the housing connection portion 213 of the first guide member 210 includes the gear 214 and the housing connection portion 223 of the second guide member 220 includes the gear 224 that fits with the gear 214.

[0055] However, the configuration for transmitting the force to the housing connection portion 223 of the second guide member 220 when the upper door 110 is opened or closed can be flexibly modified.

[0056] For example, gear 214 and gear 224 may not be directly interlocked but may be connected via one or more other gears.

[0057] Furthermore, as a configuration for realizing transmission of force to the housing connection portion 223 of the second guide member 220 in association with the opening and closing of the upper door 110, a pulley, a belt, or the like can also be employed.

[0058] Next, the simultaneous opening and closing of the upper door 110 and the side door 120 achieved by the first guide member 210 and the second guide member 220 according to this embodiment will be described in detail with reference to Figures 5, 8 to 11. Note that the internal configuration of the road hydrant 10 is not shown in Figures 5, 8 to 11.

[0059] FIG. 8 shows a side view of the roadway fire hydrant 10 seen from the roadway RW side with the upper door 110 in a state of being about 1 / 4 open.

[0060] At this time, as the upper door 110 opens and closes, the force related to the opening and closing is transmitted to the first guide member 210, the second guide member 220, and the side door 120, and the side door 120 also opens to about 1 / 4 of its width.

[0061] FIG. 9 shows a side view of the roadway fire hydrant 10 seen from the roadway RW side with the upper door 110 in a state of being about half-open.

[0062] At this time, as the upper door 110 opens and closes, the force related to the opening and closing is transmitted to the first guide member 210, the second guide member 220, and the side door 120, and the side door 120 also opens about halfway.

[0063] FIG. 10 shows a side view of the roadway fire hydrant 10 seen from the roadway RW side with the upper door 110 in a state of being about 3 / 4 open.

[0064] At this time, as the upper door 110 opens and closes, the force related to the opening and closing is transmitted to the first guide member 210, the second guide member 220, and the side door 120, and the side door 120 also opens to about 3 / 4 of its original size.

[0065] FIG. 11 shows a side view of the road fire hydrant 10 with the upper door 110 in a fully open state, as viewed from the roadway RW side.

[0066] At this time, as the upper door 110 opens, the force related to the door opening is transmitted to the first guide member 210, the second guide member 220, and the side door 120, and the side door 120 also becomes fully open.

[0067] A user or maintenance person can grasp the handle 115 and open the upper door 110 in the order shown in Figures 5, 8 to 11, thereby simultaneously opening the side door 120 and opening the upper storage section 192 and the lower storage section 194.

[0068] On the other hand, a user or maintenance person can grasp the handle 115 and close the upper door 110 in the reverse order to that shown in Figures 5, 8 to 11, thereby simultaneously closing the side door 120 and also simultaneously closing the upper storage section 192 and the lower storage section 194.

[0069] The first upper door connecting portion 211 of the first guide member 210 according to this embodiment rotates together with the upper door 110 around the housing connecting portion 213 as an axis in accordance with the opening and closing operation of the upper door 110 as described above.

[0070] Furthermore, the side door connecting portion 222 of the second guide member 220 according to this embodiment rotates together with the side door 120 around the housing connecting portion 223 as an axis in accordance with the opening and closing operation of the upper door 110 as described above.

[0071] FIG. 11 shows a track 219A related to the rotation of the first upper door connection portion 211A of the first guide member 210A, a track 219B related to the rotation of the first upper door connection portion 211B of the first guide member 210B, a track 229A related to the rotation of the side door connection portion 222A of the second guide member 220A, and a track 229B related to the rotation of the side door connection portion 222B of the second guide member 220B.

[0072] For example, if the distance between the housing connection part 213A of the first guide member 210A and the first upper door connection part 211A is 190 mm, the track 219A is a semicircle with a radius of 190 mm.

[0073] Similarly, when the distance between the housing connection part 213B of the first guide member 210B and the first upper door connection part 211B is 190 mm, the track 219B is a semicircle with a radius of 190 mm.

[0074] In other words, when the distance between the housing connection part 213A and the first upper door connection part 211A and the distance between the housing connection part 213B and the first upper door connection part 211B are 190 mm, the upper door 110 will rotate along an orbit of a semicircle with a radius of 190 mm.

[0075] Furthermore, for example, when the distance between the housing connection part 223A and the side door connection part 222A of the second guide member 220A is 190 mm, the track 229A is a semicircle with a radius of 190 mm.

[0076] Similarly, when the distance between the housing connection part 223B and the side door connection part 222B of the second guide member 220B is 190 mm, the track 229B is a semicircle with a radius of 190 mm.

[0077] That is, when the distance between the housing connection part 223A and the side door connection part 222A and the distance between the housing connection part 223B and the side door connection part 222B are 190 mm, the side door 120 rotates along an orbit that is a semicircle with a radius of 190 mm.

[0078] By rotating the upper door 110 and the side door 120 along the above-mentioned trajectory when opening and closing the doors, the doors do not protrude toward either the roadway RW or the aisle PW, eliminating the possibility of obstructing passage or work.

[0079] Next, we will explain the third guide member 230 according to this embodiment. If the first guide member 210 and the second guide member 220 have sufficient strength to withstand the weight of the upper door 110 and the side door 120, the first guide member 210 and the second guide member 220 alone can realize simultaneous opening and closing of both doors.

[0080] On the other hand, the third guide member 230 described below makes it possible to more stably open and close the upper door 110 and the side door 120 and also to reduce the effort required for the opening and closing.

[0081] Fig. 12 is a diagram for explaining the positional relationship between the first guide member 210 and the third guide member 230 according to this embodiment. Fig. 12 shows a top view of the road hydrant 10.

[0082] In Fig. 12, the first guide member 210 and the third guide member 230 are shown by solid lines for the sake of visibility. Fig. 12 also illustrates an example in which the road hydrant 10 according to this embodiment is equipped with two third guide members 230A and 230B.

[0083] 12, the third guide member 230 according to this embodiment is disposed on the side of the housing 180 opposite to the side on which the first guide member 210 is disposed. That is, the third guide member 230 according to this embodiment may be disposed on the side of the housing 180 on the passage PW side.

[0084] The third guide member 230 according to this embodiment has a housing connection part 233 (also referred to as a third housing connection part) that is connected to the housing 180 and a second upper door connection part 231 that is connected to the upper door 110.

[0085] Figure 13 shows a side view of the road fire hydrant 10 as seen from the passage PW side when the upper door 110 and the side door 120 are in a fully closed state. As shown in Figure 13, when the upper door 110 and the side door 120 are in a fully closed state, the housing connection part 233 of the third guide member 230 and the second upper door connection part 231 are positioned horizontally, as are the housing connection part 213 and the first upper door connection part 211 of the first guide member 210.

[0086] 14 and 15 are diagrams for explaining the housing connection portion 233 and the second upper door connection portion 231 of the third guide member 230 according to this embodiment.

[0087] Fig. 14 shows a side view of the third guide member 230 according to this embodiment as seen from the passage PW side. Fig. 15 shows a side view in the short side direction of the housing connection part 233 and the second upper door connection part 231 of the third guide member 230 according to this embodiment.

[0088] The housing connection portion 233 of the third guide member 230 may be realized, for example, by fixing a housing fixing member 235 that passes through a hole formed at one end of the third guide member 230 to the housing 180, as shown on the left side of Figure 15.

[0089] In addition, the second upper door connection portion 231 of the third guide member 230 may be realized, for example, by passing an upper door fixing member 236 through a hole formed at the other end of the third guide member 230 and a fixed portion 117 formed on the upper door 110 and fixing the same, as shown on the right side of Figure 15.

[0090] Next, the operation of the third guide member 230 accompanying the opening of the upper door 110 will be described in detail with reference to Fig. 13 and Figs. 16 to 19. Note that in Fig. 13 and Figs. 16 to 19, the internal configuration of the road hydrant 10 is omitted from illustration.

[0091] FIG. 16 shows a side view of the road fire hydrant 10 seen from the passage PW side with the upper door 110 in a state of being about 1 / 4 open.

[0092] FIG. 17 shows a side view of the road fire hydrant 10 seen from the passage PW side with the upper door 110 in a state of being about half-open.

[0093] FIG. 18 shows a side view of the road fire hydrant 10 seen from the passage PW side with the upper door 110 in a state of being about 3 / 4 open.

[0094] FIG. 19 shows a side view of the road fire hydrant 10 with the upper door 110 in a fully open state, as viewed from the passage PW side.

[0095] One of the features of the second upper door connecting portion 231 of the third guide member 230 according to this embodiment is that it rotates together with the upper door 110 around the housing connecting portion 233 as an axis when the upper door 110 is opened or closed.

[0096] FIG. 19 shows a track 239A for rotation of the second upper door connecting portion 231A of the third guide member 230A, and a track 239B for rotation of the second upper door connecting portion 231B of the third guide member 230B.

[0097] For example, when the distance between the housing connection part 233A of the third guide member 230A and the second upper door connection part 231A is 190 mm, the track 239A is a semicircle with a radius of 190 mm.

[0098] Similarly, when the distance between the housing connection part 233B of the third guide member 230B and the second upper door connection part 231B is 190 mm, the track 239B is a semicircle with a radius of 190 mm.

[0099] The above has described in detail the third guide member 230 according to this embodiment. The third guide member 230 according to this embodiment makes it possible to more stably open and close the upper door 110 and the side door 120 and reduce the effort required for the opening and closing.

[0100] Next, a description will be given of firefighting using the roadway hydrant 10 according to this embodiment. After operating the upper door 110 and fully opening the upper door 110 and the side door 120, the user grasps the hydrant nozzle 160 and pulls out the hose 150 to the passage PW side as shown in Fig. 20, or pulls out the hose 150 to the roadway RW side as shown in Fig. 21.

[0101] In addition, after pulling out the hose 150, the user can operate the fire hydrant lever 170 in the direction of water discharge (for example, by tilting the fire hydrant lever 170 from top to bottom), thereby turning on the fire pump start switch installed separately from the road fire hydrant 10 and simultaneously opening the fire hydrant valve, thereby performing firefighting operations.

[0102] After the fire extinguishing operation is completed, the user winds up the hose 150 from the base and stores it through the opening on the roadway RW side of the lower storage section 194, which has been opened by opening the side door 120, and operates the upper door 110 to fully close the upper door 110 and the side door 120.

[0103] <<1.2.Effects>> Next, the effects achieved by the road fire hydrant 10 according to this embodiment will be described in more detail.

[0104] As described above, the upper door 110 and the side door 120 according to this embodiment rotate along a predetermined track. The upper door 110 and the side door 120 according to this embodiment do not protrude toward the roadway RW or the passage PW during opening and closing operations, so they do not interfere with passage or work on the roadway RW or the passage PW, improving safety.

[0105] Furthermore, the upper door 110 according to this embodiment may be designed to move in the closing or opening direction under its own weight. For example, when the upper door 110 is in the state shown in Fig. 8 and no artificial force is applied, it may be in the fully closed state shown in Fig. 5 under its own weight. Furthermore, when the upper door 110 is in the state shown in Fig. 10 and no artificial force is applied, it may be in the fully open state shown in Fig. 11 under its own weight.

[0106] In this way, when the upper door 110 moves in the closing or opening direction due to its own weight, it is highly unlikely that the upper door 110 will open naturally due to vibrations, wind, etc., and the storage section 190 will be opened. Therefore, there is no need to provide a key or the like to secure the upper door 110, and problems such as the upper door 110 being unable to be unlocked in an emergency can be avoided.

[0107] For example, the upper door 110 according to this embodiment may be formed to weigh about 4 kg, and the side door 120 may be formed to weigh about 2.4 kg.

[0108] In this case, when the upper door 110 and the side door 120 are in the fully closed state, a weight of about 2.4 kg is applied to the gear 224A of the second guide member 220A and the gear 224B of the second guide member 220B in the rotation direction that closes both doors. On the other hand, a weight of about 2.4 kg is applied to the gear 214A of the first guide member 210A and the gear 214B of the first guide member 210B in the rotation direction that opens the upper door 110 and the side door 120.

[0109] Therefore, the force required to lift the upper door 110 to the highest position in the movable range as shown in Figure 9 only needs to be approximately 1.6 kg or more, which is the weight of the upper door 110 (approximately 4 kg) minus the weight of the side door 120 (approximately 2.4 kg), thereby reducing the operating burden.

[0110] Similarly, the force required to pull down the upper door 110 from the highest position of the movable range as shown in FIG. 9 to the lowest position of the movable range as shown in FIG. 5 or FIG. 11 is only about 1.6 kg or more, which reduces the operational burden.

[0111] Furthermore, even if the user unintentionally removes his / her hand from the upper door 110, the impact is reduced by the weight of about 2.4 kg, improving safety.

[0112] However, the weights of the upper door 110 and the side door 120 are not limited to the examples given above and can be designed as appropriate. In addition, the operating force for opening and closing the upper door 110 can also be adjusted by adjusting the weight difference between the upper door 110 and the side door 120.

[0113] Furthermore, in the roadway hydrant 10 according to this embodiment, the hydrant nozzle 160 and the hydrant lever 170 are stored in an upper storage section 192 that is provided above the passageway PW. This allows the user to take out the hydrant nozzle 160 and operate the hydrant lever 170 above their feet even from the passageway PW side, improving convenience and safety.

[0114] Furthermore, by forming the upper door 110 according to this embodiment in an L-shape, for example as shown in the figure, it becomes possible to simultaneously open or close the upper storage section 192 and the lower storage section 194, improving convenience.

[0115] Note that upper door 110 according to this embodiment does not necessarily have to be formed in an L-shape having a right angle, but may be formed in a shape that allows for simultaneous opening and closing of upper storage section 192 and lower storage section 194. As an example, upper door 110 according to this embodiment may have a curved shape in part.

[0116] Furthermore, by arranging the first guide member 210, the second guide member 220, and the third guide member 230 according to this embodiment as shown in the figure, the following effects are achieved.

[0117] When the upper door 110 and the side door 120 are in a fully closed state, the guide members are protected from external impacts that could cause malfunctions.

[0118] When the upper door 110 and the side door 120 are fully open, the guide members do not affect the drawing out of the hose 150, etc.

[0119] The upper door 110 is supported horizontally at any time when the upper door 110 transitions from the fully open state to the fully closed state, or from the fully closed state to the fully open state.

[0120] Regardless of who operates them, the upper door 110 and the side door 120 move along the same trajectory and are in the fully closed or fully open state at the same position.

[0121] Although the preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited to these examples. It is clear that a person skilled in the art to which the present invention pertains can conceive of various modifications and alterations within the scope of the technical ideas set forth in the claims, and it is understood that these also naturally fall within the technical scope of the present invention.
