DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this specification and the drawings, components having substantially the same functional configurations are designated by the same reference numerals, and duplicated explanations will be omitted.

[0010] <1.1. Overview> As described above, an object of the present invention is to easily realize height adjustment of an object according to a step formed by two passages.

[0011] Recently, there are various devices and structures that are installed in association with passageways. Among the above-mentioned devices, there are some that are embedded in a step structure formed by two passageways.

[0012] An example of a device that is embedded in a step structure is a road fire hydrant that is placed in a tunnel.

[0013] 2. Description of the Related Art Tunnels formed on expressways and the like include some that are equipped with supervisory passages through which supervisors and maintenance personnel can pass and perform their work, in addition to roadways through which vehicles can pass.

[0014] The guard passages as described above are generally provided at a height of about 900 to 1000 mm from the roadway, so a step structure is formed within the tunnel between the roadway and the guard passages.

[0015] Some road fire hydrants are embedded in the step structure as described above.

[0016] In addition, the step structure formed by the roadway and the guard passageway has various heights and inclinations depending on the inclinations of the roadway and the guard passageway.

[0017] However, because typical road fire hydrants have a fixed housing height, in order to match the height of the top of the road fire hydrant with the height of the guard passage, adjustments such as adding metal fittings under the road fire hydrant's stand or increasing or decreasing the height of the roadway or guard passage are required.

[0018] However, when the height of the housing is higher than the stepped structure, such adjustment is difficult.

[0019] Furthermore, even if the height of the housing is lower than the stepped structure, the adjustment requires highly accurate measurement of the stepped structure and adjustment work.

[0020] Furthermore, since road fire hydrants are generally installed at intervals of approximately 50 meters inside tunnels, if the heights of all road fire hydrants placed inside the tunnel were to be adjusted, an increase in construction labor is expected.

[0021] Therefore, the present invention has been made in consideration of the above problems, and an object of the present invention is to provide a new and improved housing that allows easy height adjustment to suit steps.

[0022] To this end, in one embodiment of the present invention, a housing that is embedded and installed in a step structure formed by a first passage and a second passage having a height difference from the first passage includes a lower part 110 of the housing that is arranged on the side of the first passage, a cover part 120 that covers the upper end of the lower part 110 of the housing, and an adjustment part 130 that is provided so as to adjust the height of the cover part 120 to match the height of the second passage.

[0023] According to the above-mentioned configuration, it is possible to easily adjust the housing height in accordance with the step formed by the two passages, and it is possible to significantly reduce the number of steps required for the adjustment.

[0024] The configuration of a housing according to an embodiment of the present invention will be described in detail below. Note that, in the following, a case in which the housing according to this embodiment is a road fire hydrant 10 will be mainly described as an example.

[0025] On the other hand, the housing according to this embodiment is not limited to this example, and can be applied to various devices arranged in a stepped structure.

[0026] For example, the housing according to this embodiment may be applied to a device that is arranged on a stepped structure formed by a railway line and a platform.

[0027] <<1.2. Configuration example of road fire hydrant 10>> First, an outline of the configuration of a road fire hydrant 10 according to this embodiment will be described with reference to Figs. 1 and 2.

[0028] Fig. 1 is a diagram for explaining the external configuration of a road fire hydrant 10 according to this embodiment. Fig. 1 shows the external configuration of the road fire hydrant 10 according to this embodiment as viewed from the front, top, and side.

[0029] Moreover, Fig. 2 is a diagram for explaining the internal configuration of the road fire hydrant 10 according to this embodiment. Fig. 2 shows the internal configuration of the front, top, and side of the road fire hydrant 10 according to this embodiment.

[0030] The road fire hydrant 10 according to this embodiment includes a separable lower housing part 110 and a cover part 120.

[0031] The lower housing part 110 according to this embodiment is disposed on the road side of the roadway RW (an example of a first passage) and includes a roadway side fire hydrant door 111 that can be opened from the roadway RW side.

[0032] By opening the roadway side fire hydrant door 111, a user can access a fire hydrant nozzle 152 and a fire hydrant lever 154 connected to a hose 150 arranged inside the lower housing part 110.

[0033] The roadway side fire hydrant door 111 according to this embodiment may be, for example, a sliding door that slides in the left-right direction. In this case, the roadway side fire hydrant door 111 does not protrude to the roadway RW side, so that the possibility of interfering with fire extinguishing activities on the roadway RW side can be eliminated.

[0034] Moreover, the lid 120 according to this embodiment is configured to cover the upper end of the lower housing part 110, and is provided so as to be adjustable according to the height of the guard passage PW (an example of a second passage).

[0035] The cover portion 120 according to this embodiment includes a first maintenance door 121, a second maintenance door 122, and a monitor passage side fire hydrant door 123, which open while rotating upward.

[0036] The first maintenance door 121 and the second maintenance door 122 according to this embodiment are doors used for accessing various internal structures when a maintenance worker performs maintenance work on the road fire hydrant 10.

[0037] On the other hand, the lifeguard passage side fire hydrant door 123 according to this embodiment is a door for allowing access to the fire hydrant nozzle 152 and the fire hydrant lever 154 from the lifeguard passage PW side.

[0038] The fire hydrant door 123 on the guard passage side allows the user to evacuate to the guard passage PW and then perform firefighting activities more safely.

[0039] Also, one of the features of the road fire hydrant 10 according to this embodiment is that it is equipped with an adjustment part 130 that is provided so as to be able to adjust the height of the cover part 120 in accordance with the height of the monitor passage PW.

[0040] The road fire hydrant 10 according to this embodiment may include four adjustment parts 130a to 130d that can adjust the height of the four corners of the cover part 120 independently.

[0041] Hereinafter, the height adjustment of the cover part 120 by the adjustment part 130 according to this embodiment will be described in detail.

[0042] First, adjustment when the roadway RW and the guard passage PW are approximately parallel will be described.

[0043] FIG. 3 is a diagram for explaining an example of the configuration of the adjustment section 130 according to this embodiment and an overview of the height adjustment of the cover section 120 by the adjustment section 130. As shown in FIG.

[0044] The adjustment portion 130 according to this embodiment is fixed to a fixing plate 112 provided on the lower part 110 of the housing.

[0045] For this purpose, as shown in FIG. 3, the adjustment part 130 in this embodiment includes a rod-shaped member 131 that passes through an attachment hole formed in the fixed plate 112, a support base 132 that is connected to the upper end of the rod-shaped member 131 and contacts the lower surface of the cover part 120, and a fixing member 134 that fixes the rod-shaped member 131 to the fixed plate 112.

[0046] Moreover, adjustment unit 130 according to this embodiment may further include angle adjustment member 133 that is disposed between rod-shaped member 131 and support base 132 and that is capable of adjusting the angle of support base 132 relative to rod-shaped member 131. Details of the function of angle adjustment member 133 according to this embodiment will be described separately.

[0047] The rod-shaped member 131 according to the present embodiment may be, for example, a bolt, etc. The fixing member 134 according to the present embodiment may be, for example, a nut, etc.

[0048] The adjustment portion 130 may further include a spring washer 135 and a washer 136 .

[0049] The adjustment section 130 according to this embodiment makes it possible to adjust the height of the lid section 120 by adjusting the fixed height of the rod-shaped member 131 .

[0050] Hereinafter, it is assumed that the housing height (the height from the bottom surface of the housing lower part 110 to the top surface of the cover part 120) of the road fire hydrant 10 before adjustment is 900 mm.

[0051] Here, if the elevation difference between the roadway RW and the monitor passage PW of the road fire hydrant 10 is 920 mm, and the roadway RW and the monitor passage PW are approximately parallel, the housing height of the road fire hydrant 10 is required to be increased by 20 mm overall.

[0052] In this case, as shown on the right side of FIG. 3, all of the adjustment portions 130a to 130d may be fixed to the fixing plates 112a to 112d, respectively, so as to protrude upward by an additional 20 mm compared to the initial state shown in the center of FIG.

[0053] By making the above adjustment, the height of the four corners of the cover portion 120 can be increased by a uniform 20 mm, making it possible to match the housing height of the road fire hydrant 10 with the height of the monitor passage PW.

[0054] On the other hand, if the difference in elevation between the roadway RW and the monitor passage PW of the road fire hydrant 10 is 880 mm and the roadway RW and the monitor passage PW are approximately parallel, the housing height of the road fire hydrant 10 needs to be lowered by 20 mm overall.

[0055] In this case, as shown on the left side of FIG. 3, all of the adjustment portions 130a to 130d may be fixed to the fixing plates 112a to 112d, respectively, so as to protrude downward by an additional 20 mm compared to the initial state shown in the center of FIG.

[0056] By making the above adjustment, the height of the four corners of the cover portion 120 can be uniformly reduced by 20 mm, making it possible to match the housing height of the road fire hydrant 10 with the height of the guard passage PW.

[0057] The above describes the adjustment when the roadway RW and the guard passage PW are approximately parallel to each other.

[0058] In addition, in the above-mentioned adjustment, the heights of the four corners of the cover portion 120 are uniformly adjusted up and down, so that the fixing positions of the adjustment portions 130a to 130d relative to the mounting holes 113a to 113b provided in the fixing plates 112a to 112d, respectively, have the same positional relationship as shown in FIG.

[0059] Next, adjustment when the roadway RW and the guard passage PW are not substantially parallel will be described.

[0060] First, a case where the monitor passage PW has an inclination in the width direction of the road fire hydrant 10 will be described.

[0061] FIG. 5 is a diagram showing an example in which the monitor passage PW has an inclination in the width direction of the road fire hydrant 10. In FIG.

[0062] In the example shown in FIG. 5, the monitor passage PW has an inclination that gradually increases from the right shoulder direction (left direction in the figure) of the road fire hydrant 10 to the left shoulder direction (right direction in the figure).

[0063] In this case, it is necessary to adjust the adjustment parts 130a to 130d so that the left shoulder of the road fire hydrant 10 is higher than the right shoulder, and to match the inclination of the cover part 120 with the inclination of the monitor passage PW.

[0064] FIG. 6 is a diagram for explaining adjustment when the monitor passage PW has an inclination in the width direction of the road fire hydrant 10. In FIG.

[0065] Here, an example will be described in which the housing height of the roadway fire hydrant 10 is 900 mm when not adjusted, and the height of the right shoulder of the roadway fire hydrant 10 is adjusted to 880 mm and the height of the left shoulder is adjusted to 920 mm.

[0066] In the above case, the adjustment parts 130a and 130b arranged on the right shoulder of the road fire hydrant 10 are fixed to the fixing plates 112a and 112b, respectively, so as to protrude downward by an additional 20 mm compared to the initial state, as shown on the left side of Figure 6.

[0067] On the other hand, the adjustment parts 130c and 130d arranged on the left shoulder of the road fire hydrant 10 are fixed to the fixing plates 112c and 112d, respectively, so as to protrude further upward by 20 mm compared to the initial state, as shown on the right side of FIG.

[0068] In this case, the lid portion 120 has an inclination of about 2°, and the supports 132a to 132d in contact with the lower surface of the lid portion 120 are also inclined at about 2° with respect to the rod-shaped members 131a to 131d, respectively.

[0069] In order to achieve the above-mentioned tilt, the adjustment unit 130 of this embodiment may include an angle adjustment member 133 that is arranged between the rod-shaped member 131 and the support base 132 and enables adjustment of the angle of the support base 132 relative to the rod-shaped member 131.

[0070] The angle adjustment member 133 according to this embodiment may be, for example, in a spherical shape that is freely rotatable together with the support base 132 at the upper end of the rod-shaped member 131 .

[0071] By adjusting as described above, the housing heights of the right and left shoulders of the road fire hydrant 10 can be made different heights, making it possible to match the height of the monitor passage PW, which has a slope in the width direction of the road fire hydrant 10.

[0072] When the above-mentioned adjustment is performed, the horizontal distance between the adjustment units 130a and 130c and the horizontal distance between the adjustment units 130b and 130d become slightly shorter than in the initial state.

[0073] Furthermore, in order to prevent contact between the cover portion 120 and the housing lower portion 110, the adjustment portions 130a to 130d are fixed after their positions relative to the mounting holes 113a to 113d are adjusted.

[0074] In the example shown in the lower part of FIG. 6, each of rod-shaped members 131c and 131d is slidably adjusted and fixed in attachment hole 113c or 113d so as to approach the center of lower housing part 110 in the width direction.

[0075] Next, adjustment when the monitor passage PW has an incline in the depth direction of the road fire hydrant 10 will be described.

[0076] FIG. 7 is a diagram showing an example in which the monitor passage PW has an incline in the depth direction of the road fire hydrant 10. In FIG.

[0077] In the example shown in FIG. 7, the monitor passage PW has an inclination that gradually increases from the front direction (right direction in the drawing) of the road fire hydrant 10 to the rear direction (right direction in the drawing).

[0078] In this case, it is necessary to adjust the adjustment parts 130a to 130d so that the rear face of the road fire hydrant 10 is higher than the front face, and to match the inclination of the cover part 120 with the inclination of the monitor passage PW.

[0079] FIG. 8 is a diagram for explaining adjustment when the monitor passage PW has an incline in the depth direction of the road fire hydrant 10. In FIG.

[0080] Here, an example will be described in which the housing height of the roadway fire hydrant 10 is 900 mm when not adjusted, and the height of the front of the roadway fire hydrant 10 is adjusted to 880 mm and the height of the rear is adjusted to 900 mm.

[0081] In the above case, the adjustment parts 130b and 130d arranged on the front side of the road fire hydrant 10 are fixed to the fixing plates 112b and 112d, respectively, so as to protrude downward by an additional 20 mm compared to the initial state, as shown on the left side of Figure 8.

[0082] On the other hand, the adjustment parts 130a and 130c arranged on the rear side of the road fire hydrant 10 are fixed to the fixing plates 112a and 112c, respectively, at the same height as in the initial state, as shown on the right side of FIG.

[0083] In this case, the lid portion 120 has an inclination of about 5°, and the supports 132a to 132d in contact with the lower surface of the lid portion 120 are also inclined at about 5° relative to the rod members 131a to 131d, respectively.

[0084] Furthermore, when the above-mentioned adjustment is performed, the horizontal distance between the adjustment parts 130a and 130b and the horizontal distance between the adjustment parts 130c and 130d become shorter than in the initial state.

[0085] Furthermore, in order to prevent contact between the cover portion 120 and the housing lower portion 110, the adjustment portions 130a to 130d are fixed after their positions relative to the mounting holes 113a to 113d are adjusted.

[0086] In the example shown in the lower part of FIG. 8, each of the rod-shaped members 131a to 131d is slidably adjusted in the attachment holes 113a to 113d so as to approach the front side of the lower housing part 110, and then fixed.

[0087] For this reason, the mounting hole 113 according to this embodiment is formed with a size and shape that allows the above-mentioned sliding adjustment.

[0088] By adjusting as described above, the housing heights of the front and rear of the road fire hydrant 10 can be made different heights, making it possible to match the height of the monitor passage PW, which has a slope in the depth direction of the road fire hydrant 10.

[0089] The adjustment of the housing height of the road fire hydrant 10 by the adjustment unit 130 according to this embodiment has been described above with specific examples.

[0090] In addition to the examples given above, the adjustment units 130a to 130d according to this embodiment can also adjust the housing heights at the four corners to be different from one another.

[0091] By independently adjusting the adjustment sections 130a to 130d, for example, the housing height can be adjusted to decrease in the order of rear right shoulder > front right shoulder > rear left shoulder > front left shoulder, or the housing height can be adjusted to decrease in the order of rear left shoulder > rear right shoulder > front left shoulder > front right shoulder.

[0092] Next, a usage image of the road fire hydrant 10 after the housing height has been adjusted will be described with reference to FIG.

[0093] Figure 9 shows a monitor passage PW that gradually increases in slope from the right shoulder direction (left direction in the figure) to the left shoulder direction (right direction in the figure) of the road fire hydrant 10, and a road fire hydrant 10 whose housing height has been adjusted to match the monitor passage PW.

[0094] By adjusting as shown in FIG. 9, for example, a maintenance worker can open the first maintenance door 121 and the second maintenance door 122 above the road fire hydrant 10 and the flat supervisory walkway PW, and perform various maintenance tasks more safely.

[0095] In addition, for example, a user performing firefighting activities can open the fire hydrant door 123 on the monitor's passage side on the road fire hydrant 10 and the flat monitor's passage PW to access the fire hydrant nozzle 152 and the fire hydrant lever 154, thereby performing firefighting activities more safely.

[0096] In order to enable the user to perform fire extinguishing activities more quickly, the fire hydrant nozzle 152 and the fire hydrant lever 154 according to this embodiment may be fixed to the inside of the fire hydrant door 123 on the monitor passage side.

[0097] With this, even if the housing height of the road fire hydrant 10 is adjusted, the fire hydrant nozzle 152 and the fire hydrant lever 154 are positioned above the storage section that stores the hose 150, eliminating the possibility of interfering with the withdrawal of the hose 150.

[0098] <2. Summary> As described above, the housing according to one embodiment of the present invention is embedded and installed in a step structure formed by a first passage and a second passage having a height difference from the first passage. The housing according to one embodiment of the present invention includes a lower housing part 110 installed on the side of the first passage, a lid part 120 covering an upper end of the lower housing part 110, and an adjustment part 130 provided to adjust the height of the lid part 120 according to the height of the second passage.

[0099] According to the above-mentioned configuration, the height can be easily adjusted according to the step.
