[0011] Preferred embodiments of the present invention will be described in detail below with reference to the attached drawings. In this specification and drawings, components having substantially the same functional configuration are denoted by the same reference numerals, and redundant descriptions will be omitted.

[0012] Furthermore, in this specification and drawings, when describing multiple identical functional configurations to distinguish them, an alphabet letter 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 letter may be omitted, and a description common to all identical functional configurations may be provided.

[0013] Furthermore, in drawings, even if a component is labeled with a reference numeral in other drawings, if that component can be identified by its positional relationship with other components, the reference numeral may be omitted to prioritize the visibility of the drawing.

[0014] <1. Embodiments> <<1.1. Configuration Example 10 of Road Hydrant>> First, referring to FIGS. 1 and 2, a configuration example of a road hydrant 10 according to an embodiment of the present invention will be described.

[0015] FIG. 1 is a diagram mainly for explaining the external structure of the road hydrant 10 according to the present embodiment. FIG. 2 is a diagram mainly for explaining the internal structure of the road hydrant 10 according to the present embodiment.

[0016] On the lower right side of FIGS. 1 and 2, a side view in the short side direction of the road hydrant 10 according to the present embodiment is shown. As shown in the side view in the short side direction, the road hydrant 10 according to the present embodiment is installed between a roadway RW and a passage PW parallel to the roadway RW in a tunnel or the like.

[0017] Note that the passage PW is provided for people to pass and work. The above work includes, for example, fire extinguishing work and maintenance work. In addition, the above passage includes, in addition to the passage for carrying out the above work, the passage associated with evacuation.

[0018] In addition, on the upper part of FIGS. 1 and 2, a top view of the road hydrant 10 according to the present embodiment is shown. In addition, on the lower left side of FIGS. 1 and 2, a side view in the longitudinal direction of the road hydrant 10 according to the present embodiment is shown.

[0019] As shown in FIG. 2, the road hydrant 10 according to the present embodiment includes a storage portion 120 composed of an upper storage portion 122 and a lower storage portion 124 inside a housing 110.

[0020] The upper storage portion 122 may be, for example, the upper space in the space of the storage portion 120 with reference to the upper surface of the passage PW. On the other hand, the lower storage portion 124 may be the lower space in the space of the storage portion 120 with reference to the upper surface of the passage PW.

[0021] For example, a hose 150 is stored in the lower storage section 124. On the other hand, a fire hydrant nozzle 160 connected to the hose 150 and a fire hydrant lever 170 are stored in the upper storage section 122.

[0022] In addition to the fire hydrant nozzle 160 and fire hydrant lever 170, the upper storage section 122 may also house electrical components for operating a red indicator light, push button, response lamp, etc., which are located outside the housing 110.

[0023] Furthermore, the road fire hydrant 10 according to this embodiment is equipped with a door 130 used for opening and closing the storage section 120.

[0024] Users performing firefighting operations or maintenance personnel performing maintenance on the road fire hydrant 10 can open and close the storage compartment 120 by gripping the handle 135 and opening and closing the door 130.

[0025] Figures 1 and 2 illustrate the configuration when the door 130 is fully open. As shown in Figures 1 and 2, when the door 130 is fully open, both the upper storage section 122 and the lower storage section 124 are opened.

[0026] Therefore, users and maintenance personnel performing firefighting operations can easily access the fire hydrant nozzle 160 stored in the upper storage section 122, whether from the roadway RW side or the walkway PW side, and can easily pull out the hose 150 stored in the lower storage section 124.

[0027] Furthermore, as shown in Figures 1 and 2, even when the door 130 is fully open, it does not protrude toward either the roadway RW or the passageway PW. In addition, as will be described in detail later, one of the features of the door 130 according to this embodiment is that it does not protrude toward either the roadway RW or the passageway PW at any stage of opening or closing. With such a configuration, traffic and work in the roadway RW and passageway PW are not obstructed, and safety is improved.

[0028] Furthermore, in order to enable the opening and closing of the door 130 as described above, the road fire hydrant 10 according to this embodiment is equipped with a guide member 140.

[0029] For example, Figures 1 and 2 illustrate a case in which the road fire hydrant 10 according to this embodiment is equipped with four guide members 140A to 140D.

[0030] The guide member 140 and the opening and closing of the door 130 achieved by the guide member 140 will be described in detail below.

[0031] Figure 3 is a diagram illustrating an example of the shape of the guide member 140 according to this embodiment. The upper part of Figure 3 shows a top view of the guide member 140 mounted on the road fire hydrant 10. On the other hand, the lower part of Figure 3 shows a side view of the guide member 140 mounted on the road fire hydrant 10.

[0032] As shown in Figure 3, the guide member 140 according to this embodiment has holes 145 at one end and the other end.

[0033] Figure 4 is a diagram illustrating the first connection portion 141 and the second connection portion 142 of the guide member 140 according to this embodiment.

[0034] The guide member 140 according to this embodiment has a first connecting portion 141 that connects to the housing 110 on the roadway RW side or the passageway PW side, and a second connecting portion 142 that connects to the door 130.

[0035] Figure 4 shows top views of the first connection parts 141A to 141D and the second connection parts 142A to 142D when the guide members 140A to 140D are mounted on the road fire hydrant 10.

[0036] For example, the second connection portion 142A of the guide member 140A may be realized by fixing a mounting member 147 that passes through a hole 145A formed at one end of the guide member 140A to the door 130, as shown in the first row of the bottom row of Figure 4.

[0037] Alternatively, for example, the first connection portion 141A of the guide member 140A may be realized by fixing a mounting member 147 that passes through a hole 145A formed at the other end of the guide member 140A to the housing 110, as shown in the second row from the bottom of Figure 4.

[0038] The first connection portion 141B and the second connection portion 142B of guide member 140B, the first connection portion 141C and the second connection portion 142C of guide member 140C, and the first connection portion 141D and the second connection portion 142D of guide member 140D may be implemented similarly.

[0039] Next, with reference to Figures 5 to 9, the opening and closing operation of the door 130 realized by the guide member 140 according to this embodiment will be described in detail.

[0040] Figure 5 shows a top view (upper row), a side view in the short direction (lower left row), and a side view in the long direction (lower right row) of a road fire hydrant 10 with the door 130 fully closed.

[0041] Figure 6 shows a top view (upper row), a side view in the short direction (lower left row), and a side view in the long direction (lower right row) of a road fire hydrant 10 with the door 130 open about one-quarter of the way.

[0042] Figure 7 shows a top view (upper row), a side view in the short direction (lower left row), and a side view in the long direction (lower right row) of a road fire hydrant 10 with the door 130 open about halfway.

[0043] Figure 8 shows a top view (upper row), a side view in the short direction (lower left row), and a side view in the long direction (lower right row) of a road fire hydrant 10 with the door 130 open about three-quarters of the way.

[0044] Figure 9 shows a top view (upper row), a side view in the short direction (lower left row), and a side view in the long direction (lower right row) of a road fire hydrant 10 with the door 130 fully open.

[0045] Users and maintenance personnel can simultaneously open the upper storage compartment 122 and the lower storage compartment 124 by grasping the handle 135 and opening the door 130 in the order shown in Figures 5 to 9.

[0046] On the other hand, users and maintenance personnel can simultaneously close the upper storage section 122 and the lower storage section 124 by grasping the handle 135 and closing the door 130 in the reverse order of those shown in Figures 5 to 9.

[0047] One of the features of the second connecting portion 142 of the guide member 140 according to this embodiment is that it rotates together with the door 130 on the first connecting portion 141 as an axis in conjunction with the operation of the door 130 related to opening or closing the storage portion 120 as described above.

[0048] Figure 9 shows the trajectory 149A related to the rotation of the second connection portion 142A of the guide member 140A, and the trajectory 149C related to the rotation of the second connection portion 142C of the guide member 140C.

[0049] For example, if the distance between the first connecting portion 141A and the second connecting portion 142A of the guide member 140A is 190 mm, then the track 149A will be a semicircle with a radius of 190 mm.

[0050] Similarly, if the distance between the first connecting portion 141C and the second connecting portion 142C of the guide member 140C is 190 mm, then the track 149C will be a semicircle with a radius of 190 mm.

[0051] In other words, if the distance between the first connection part 141A and the second connection part 142A, and the distance between the first connection part 141C and the second connection part 142C are 190 mm, the door 130 will rotate on a semicircle with a radius of 190 mm.

[0052] As the door 130 rotates along the aforementioned trajectory when opening and closing, it does not protrude toward either the roadway RW side or the passageway PW side, thus eliminating the possibility of obstructing passage or work.

[0053] Next, a firefighting operation using the road fire hydrant 10 according to this embodiment will be described. After fully opening the door 130, the user grasps the fire hydrant nozzle 160 and pulls out the hose 150 towards the passage PW side as shown in Figure 10, or pulls out the hose 150 towards the roadway RW side as shown in Figure 11.

[0054] Furthermore, 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 activation switch, which is installed separately from the road fire hydrant 10, and simultaneously opening the fire hydrant valve, allowing them to perform firefighting operations.

[0055] Furthermore, after the firefighting operation is completed, the user may open the hose storage door 180 to open the lower storage section 124 and then wind up and store the pulled-out hose 150 from its base.

[0056] <<1.2. Effects>> Next, the effects achieved by the road fire hydrant 10 according to this embodiment will be described in more detail.

[0057] As described above, the door 130 according to this embodiment rotates along a predetermined track by being connected to the guide member 140. Since the door 130 according to this embodiment does not protrude toward either the roadway RW side or the passageway PW side when open or closed, it does not obstruct passage or work on the roadway RW and passageway PW, thereby improving safety.

[0058] Furthermore, the door 130 according to this embodiment may be designed to operate in the closing or opening direction by its own weight. For example, if no artificial force is applied to the door 130 in the state shown in Figure 6, it may be fully closed by its own weight as shown in Figure 5. Also, for example, if no artificial force is applied to the door 130 in the state shown in Figure 8, it may be fully open by its own weight as shown in Figure 9.

[0059] Thus, when the door 130 moves in the closing or opening direction due to its own weight, the possibility of the door 130 opening spontaneously due to vibrations or wind and the storage compartment 120 being opened is extremely low. Therefore, it is not necessary to provide a lock or the like to secure the door 130, and problems such as the door 130 not being able to be unlocked in an emergency can be avoided.

[0060] Furthermore, in the road fire hydrant 10 according to this embodiment, the fire hydrant nozzle 160 and the fire hydrant lever 170 are stored in an upper storage section 122 that is provided above the passageway PW. This allows the user to retrieve the fire hydrant nozzle 160 and operate the fire hydrant lever 170 from above their feet, even when approaching from the passageway PW side, thereby improving convenience and safety.

[0061] Furthermore, since the door 130 according to this embodiment is formed in an L-shape, as shown in the figure, it becomes possible to open or close the upper storage section 122 and the lower storage section 124 simultaneously, thereby improving convenience.

[0062] Furthermore, the door 130 according to this embodiment does not necessarily have to be formed in an L-shape with right angles; it is sufficient if it is formed in a shape that allows the upper storage section 122 and the lower storage section 124 to be opened or closed simultaneously. For example, the door 130 according to this embodiment may have a curved shape in part.

[0063] Furthermore, by arranging the guide member 140 according to this embodiment as shown in the figure, the following effects can be achieved.

[0064] When the door 130 is in the fully closed position, the guide member 140 is protected from external impacts and other factors that could cause malfunction.

[0065] When the door 130 is fully open, the guide member 140 does not affect the pulling out of the hose 150, etc.

[0066] The door 130 is supported horizontally at any point in time when it transitions from the fully open state to the fully closed state, or from the fully closed state to the fully open state.

[0067] Regardless of who operates it, the door 130 moves along the same trajectory and reaches either a fully closed or fully open position at the same location.

[0068] However, the road fire hydrant 10 according to this embodiment does not necessarily have to be equipped with four (two pairs) guide members 140 as shown in the figure.

[0069] For example, the road fire hydrant 10 may be equipped with one pair of guide members 140, or it may be equipped with three pairs of guide members.

[0070] Furthermore, for example, if the guide member 140 can adequately support the weight of the door 130, the guide member may be provided only on either the roadway RW side or the passageway PW side.

[0071] The number and arrangement of the guide members 140 according to this embodiment can be flexibly modified.

[0072] Although preferred embodiments of the present invention have been described in detail above with reference to the attached drawings, the present invention is not limited to these examples. It is clear to any person with ordinary skill in the art to which the present invention belongs that various modifications or alterations can be conceived within the scope of the technical idea described in the claims, and these are also understood to fall within the technical scope of the present invention.
