The preferred embodiment of the present invention will be described in detail below with reference to the attached drawings. Note that in this specification and the drawings, components having substantially the same functional configuration are designated by the same reference numerals to avoid redundant description.

<1.1. Overview>
As described above, an object of the present invention is to easily realize height adjustment of an object in accordance with a step formed by two passages.

In recent years, there are various devices and structures that are installed in association with passageways. In addition, some of the above-mentioned devices are embedded in the step structure formed by two passageways.

One example of a device that is embedded in a step structure is a road fire hydrant installed inside a tunnel.

Some tunnels on expressways and other roads have guard passages for guards and maintenance personnel to use and carry out their work, in addition to roadways for vehicles to use.

The guard passages described above are generally set up at a height of about 900 to 1000 mm above the roadway. As a result, a step structure is formed within the tunnel between the roadway and the guard passages.

Some road fire hydrants are embedded into the step structure shown above.

The step structure formed by the roadway and the guard passageway has various heights and slopes depending on the slope of the roadway and the guard passageway.

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's 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's passage are required.

However, if the housing height is higher than the step structure, such adjustments are difficult.

Even if the housing height is lower than the step structure, adjustment requires highly accurate measurement of the step structure and adjustment work.

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

The present invention was made in consideration of the above problems, and the object of the present invention is to provide a new and improved housing that allows easy height adjustment according to the difference in level.

For this reason, the housing installed in the step structure formed by a first passage and a second passage having a height difference from the first passage according to one embodiment of the present invention includes a lower housing part 110 arranged on the side of the first passage, a cover part 120 covering the upper end of the lower housing part 110, and an adjustment part 130 that is provided so that the height of the cover part 120 can be adjusted to match the height of the second passage.

The above configuration makes it easy to adjust the housing height according to the step formed by the two passages, and it is possible to significantly reduce the amount of work required for the adjustment.

The configuration of the housing according to one embodiment of the present invention will be described in detail below. Note that the main example described below will be a road fire hydrant 10 as the housing according to this embodiment.

However, the housing according to this embodiment is not limited to this example and can be applied to various devices arranged in a stepped structure.

For example, the housing according to this embodiment may be applied to a device that is placed on a stepped structure formed by the tracks and the platform.

<<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 .

Figure 1 is a diagram for explaining the external configuration of a roadway fire hydrant 10 according to this embodiment. Figure 1 shows the external configuration of a roadway fire hydrant 10 according to this embodiment as viewed from the front, top, and side.

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

The road fire hydrant 10 according to this embodiment has a separable lower housing part 110 and a lid part 120.

The lower housing part 110 in this embodiment is disposed on the road side of the roadway RW (an example of a first passageway) and is equipped with a roadway side fire hydrant door 111 that can be opened from the roadway RW side.

By opening the roadway side fire hydrant door 111, the user can access the fire hydrant nozzle 152 and the fire hydrant lever 154 that are connected to the hose 150 located inside the lower housing part 110.

The roadway side fire hydrant door 111 in this embodiment may be, for example, a sliding door that slides left and right. In this case, the roadway side fire hydrant door 111 does not protrude to the roadway RW side, eliminating the possibility of interfering with firefighting activities taking place on the roadway RW side.

The lid 120 in this embodiment is configured to cover the upper end of the lower housing part 110 and is adjustable according to the height of the guard passage PW (an example of the second passage).

The cover 120 in this embodiment includes a first maintenance door 121, a second maintenance door 122, and a fire hydrant door 123 on the monitor's passage side that swing upward to open.

The first maintenance door 121 and the second maintenance door 122 in this embodiment are doors used by maintenance personnel to access various internal structures when performing maintenance work on the road fire hydrant 10.

On the other hand, the monitor passage side fire hydrant door 123 in this embodiment is a door for providing access to the fire hydrant nozzle 152 and the fire hydrant lever 154 from the monitor passage PW side.

The fire hydrant door 123 on the supervisor's passage allows the user to evacuate to the supervisor's passage PW and then carry out firefighting activities more safely.

Another feature of the road fire hydrant 10 according to this embodiment is that it is equipped with an adjustment section 130 that allows the height of the cover section 120 to be adjusted according to the height of the guard passage PW.

The road fire hydrant 10 according to this embodiment may be equipped with four adjustment parts 130a to 130d that can independently adjust the height of each of the four corners of the cover part 120.

The height adjustment of the lid portion 120 using the adjustment portion 130 according to this embodiment is described in detail below.

First, we will discuss adjustments when the roadway RW and the guard passageway PW are approximately parallel.

Figure 3 is a diagram illustrating an example of the configuration of the adjustment unit 130 according to this embodiment, and an overview of the height adjustment of the lid unit 120 by the adjustment unit 130.

The adjustment unit 130 in this embodiment is fixed to a fixing plate 112 provided on the lower housing part 110.

To this end, as shown in FIG. 3, the adjustment unit 130 according to 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 lid 120, and a fixing member 134 that fixes the rod-shaped member 131 to the fixed plate 112.

The adjustment unit 130 according to this embodiment may further include an angle adjustment member 133 that is disposed between the rod-shaped member 131 and the support base 132 and that allows the angle of the support base 132 relative to the rod-shaped member 131 to be adjusted. The function of the angle adjustment member 133 according to this embodiment will be described in detail separately.

The rod-shaped member 131 according to this embodiment may be, for example, a bolt. The fixing member 134 according to this embodiment may be, for example, a nut.

The adjustment unit 130 may further include a spring washer 135 and a washer 136.

The adjustment unit 130 in this embodiment allows the height of the lid unit 120 to be adjusted by adjusting the fixed height of the rod-shaped member 131.

In the following, it is assumed that the housing height (height from the bottom surface of the lower housing part 110 to the top surface of the cover part 120) of the road fire hydrant 10 when not adjusted is 900 mm.

Here, if the elevation difference between the roadway RW and the guard passage PW of the roadway fire hydrant 10 is 920 mm, and the roadway RW and the guard passage PW are approximately parallel, it is necessary to increase the housing height of the roadway fire hydrant 10 by 20 mm overall.

In this case, as shown on the right side of Figure 3, all of the adjustment sections 130a to 130d can be fixed to the fixing plates 112a to 112d, respectively, so that they protrude an additional 20 mm upward compared to the initial state shown in the center of Figure 3.

By adjusting as described above, the height of the four corners of the cover 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 guard passage PW.

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

In this case, as shown on the left side of Figure 3, all of the adjustment sections 130a to 130d can be fixed to the fixing plates 112a to 112d respectively so that they protrude downward by an additional 20 mm compared to the initial state shown in the center of Figure 3.

By adjusting as described above, the height of the four corners of the cover 120 can be uniformly reduced by 20 mm, making it possible to align the housing height of the road fire hydrant 10 with the height of the guard passage PW.

Above, we have explained the adjustment when the roadway RW and the guard passage PW are approximately parallel.

In addition, with the above adjustment, the heights of the four corners of the lid portion 120 are adjusted uniformly up and down, so 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, are in the same positional relationship as shown in Figure 4.

Next, we will explain the adjustments to be made when the roadway RW and the guard passageway PW are not approximately parallel.

First, we will describe the case where the monitor passage PW has an incline in the width direction of the road fire hydrant 10.

Figure 5 shows an example in which the monitor passage PW has an incline in the width direction of the road fire hydrant 10.

In the example shown in FIG. 5, the monitor passage PW has a slope 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).

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 guard passage PW.

Figure 6 is a diagram to explain the adjustment when the monitor passage PW has an incline in the width direction of the road fire hydrant 10.

Here, we will explain an example in which the housing height of the road fire hydrant 10 is 900 mm when not adjusted, and the height of the right shoulder of the road fire hydrant 10 is adjusted to 880 mm and the height of the left shoulder is adjusted to 920 mm.

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

On the other hand, the adjustment parts 130c and 130d, which are located on the left shoulder of the road fire hydrant 10, are fixed to the fixing plates 112c and 112d, respectively, so that they protrude further upward by 20 mm compared to the initial state, as shown on the right side of Figure 6.

In this case, the lid 120 will have an inclination of about 2°, and the support bases 132a to 132d that come into contact with the underside of the lid 120 will also be inclined by about 2° relative to the rod members 131a to 131d, respectively.

To achieve the above-mentioned tilt, the adjustment unit 130 according to this embodiment may include an angle adjustment member 133 that is disposed between the rod-shaped member 131 and the support base 132 and that allows the angle of the support base 132 relative to the rod-shaped member 131 to be adjusted.

The angle adjustment member 133 in this embodiment may be, for example, a spherical shape that can freely rotate together with the support base 132 at the upper end of the rod-shaped member 131.

By adjusting as described above, the housing heights of the right and left shoulders of the road fire hydrant 10 can be set to 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.

When performing the above adjustments, the horizontal distance between adjustment units 130a and 130c, and the horizontal distance between adjustment units 130b and 130d, will be slightly shorter than in the initial state.

In addition, to avoid contact between the cover 120 and the lower housing part 110, the adjustment parts 130a to 130d are fixed by adjusting their positions relative to the mounting holes 113a to 113d.

In the example shown at the bottom of Figure 6, each of the rod-shaped members 131c and 131d is slid and adjusted in the mounting hole 113c or 113d so as to approach the center of the width of the lower housing part 110, and is fixed in place.

Next, we will discuss adjustments when the monitor passage PW has an incline in the depth direction of the road fire hydrant 10.

Figure 7 shows an example in which the monitor passage PW has an incline in the depth direction of the road fire hydrant 10.

In the example shown in FIG. 7, the monitor passage PW has a slope that gradually increases from the front side (to the right in the figure) of the road fire hydrant 10 to the rear side (to the right in the figure).

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

Figure 8 is a diagram to explain the adjustment when the monitor passage PW has an incline in the depth direction of the road fire hydrant 10.

Here, we will explain an example in which the housing height of the road fire hydrant 10 is 900 mm when not adjusted, and the height of the front of the road fire hydrant 10 is adjusted to 880 mm and the height of the rear is adjusted to 900 mm.

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 further downward by 20 mm compared to the initial state, as shown on the left side of Figure 8.

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 Figure 8.

In this case, the lid 120 will have an inclination of about 5°, and the support bases 132a to 132d that come into contact with the underside of the lid 120 will also be inclined by about 5° relative to the rod members 131a to 131d, respectively.

In addition, when performing the above-described adjustment, the horizontal distance between adjustment units 130a and 130b, and the horizontal distance between adjustment units 130c and 130d, become shorter compared to the initial state.

In addition, to avoid contact between the cover 120 and the lower housing part 110, the adjustment parts 130a to 130d are fixed by adjusting their positions relative to the mounting holes 113a to 113d.

In the example shown at the bottom of Figure 8, each of the rod-shaped members 131a to 131d is slid and adjusted so as to approach the front side of the lower housing part 110 in the mounting holes 113a to 113d and fixed.

For this reason, the mounting hole 113 in this embodiment is formed with a size and shape that allows for the above-mentioned sliding adjustment.

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

The above describes the adjustment of the housing height of the road fire hydrant 10 by the adjustment unit 130 of this embodiment, using a specific example.

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 each other.

By independently adjusting the adjustment units 130a to 130d, for example, it is possible to adjust the case height so that it decreases in the order of rear right shoulder > front right shoulder > rear left shoulder > front left shoulder, or rear left shoulder > rear right shoulder > front left shoulder > front right shoulder.

Next, referring to Figure 9, we will explain how the road fire hydrant 10 will be used after the housing height has been adjusted.

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.

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 supervisor's walkway PW, and perform various maintenance tasks more safely.

For example, a user performing firefighting activities can open the fire hydrant door 123 on the guard passage side on the road fire hydrant 10 and the flat guard passage PW to access the fire hydrant nozzle 152 and the fire hydrant lever 154, allowing the user to perform firefighting activities more safely.

In order to enable the user to perform fire-fighting 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's passage side.

As a result, 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.
