Summary of the Invention

Problems to be Solved by the Invention

[0004] When a sonar sensor is provided on a pole such as a utility pole as in the traffic safety system described in Patent Document 1, there may be a case where it is desired to protect the sonar sensor from rainwater.

[0005] An object of the present invention is to provide a pole capable of protecting an ultrasonic sensor from rainwater.

Means for Solving the Problems

[0006] The present invention [1] includes a pole installed outdoors, the pole including a pole body, a housing portion capable of housing an ultrasonic sensor and having an opening through which ultrasonic waves from the ultrasonic sensor can pass, and a moisture-permeable waterproof sheet for closing the opening.

[0007] According to such a configuration, the ultrasonic sensor can be housed in the housing portion to protect the ultrasonic sensor from rainwater and the like.

[0008] Furthermore, since the housing is provided with an opening through which ultrasonic waves from the ultrasonic sensor can pass, it is possible to suppress the obstruction of ultrasonic wave emission from the ultrasonic sensor by the housing.

[0009] Furthermore, the opening of the containment area is closed with a breathable waterproof sheet. The breathable waterproof sheet allows gas (water vapor) to pass through but not liquid (water).

[0010] Therefore, ultrasonic waves from the ultrasonic sensor pass through the breathable waterproof sheet, while rainwater does not.

[0011] This allows ultrasonic waves from the ultrasonic sensor to be transmitted to the outside of the housing through the opening, while preventing rainwater from entering the housing through the opening.

[0012] As a result, the ultrasonic sensor can be protected from rainwater while suppressing interference with the emission of ultrasonic waves from the sensor.

[0013] The present invention [2] further comprises a first cover having a through hole through which ultrasonic waves from the ultrasonic sensor can pass and covering the opening, and a second cover having a through hole through which ultrasonic waves from the ultrasonic sensor can pass and overlapping the first cover, wherein the breathable waterproof sheet includes the pole of [1] disposed between the first cover and the second cover.

[0014] With this configuration, the first cover and the second cover can protect the breathable waterproof sheet.

[0015] As a result, it is possible to prevent rainwater from entering the containment area by tearing the breathable waterproof sheet.

[0016] The present invention [3] includes the pole described in [1] or [2] above, wherein the housing is located inside the pole body and the opening is located on the side of the pole body.

[0017] With this configuration, the ultrasonic sensor can be housed in the space inside the pole itself. [Effect of the Invention]

[0018] According to the pole of the present invention, the ultrasonic sensor can be protected from rainwater. [Brief Description of the Drawings]

[Figure 3] FIG. 3 is a cross-sectional view taken along the line B-B of the pole shown in FIG. 2. [Modes for Carrying Out the Invention]

[0020] 1. Pole As shown in FIG. 1, the pole 1 is installed outdoors. The use of the pole 1 is not limited. The pole 1 is used, for example, as a service pole, a lighting pole, a wireless Pillars and and is used as such. As shown in FIGS. 1 and 2, the pole 1 includes a pole body 2, a housing portion 3, a first cover 4 (see FIG. 2), a packing 5 (see FIG. 2), a moisture-permeable waterproof sheet 6 (see FIG. 2), and a second cover 7 (see FIG. 2).

[0021] (1) Pole body The pole body 2 is made of steel. The pole body 2 is made of, for example, a steel pipe. Examples of the steel pipe include a carbon steel pipe for general structure (JIS G 3444:2021). The pole body 2 may be made of concrete. The pole body 2 has, for example, a cylindrical shape or a columnar shape. The outer surface of the pole body 2 may be painted.

[0022] (2) Housing portion As shown in Figure 2, the housing section 3 is capable of housing the ultrasonic sensor S. In this embodiment, the housing section 3 is part of the pole body 2. The housing section 3 is located inside the pole body 2. If the pole body 2 is a steel pipe, the housing section 3 can be provided within the internal space of the steel pipe. The housing section 3 has at least a support member for supporting the ultrasonic sensor S. The support member is not shown. The support member is attached to the inner surface of the pole body 2. The housing section 3 may also be a box located outside the pole body 2. The housing section 3 has an opening 31.

[0023] The opening 31 is located on the side surface 21 of the pole body 2. If the pole body 2 is a steel pipe, the opening 31 is formed as a through-hole in the peripheral wall of the steel pipe. The opening 31 is connected to the internal space of the housing 3. Ultrasonic waves from the ultrasonic sensor S can pass through the opening 31. As long as ultrasonic waves from the ultrasonic sensor S can pass through, the size and shape of the opening 31 are not limited. In this embodiment, the opening 31 is substantially rectangular.

[0024] (3) Cover 1 The first cover 4 covers the entire opening 31. The first cover 4 supports the breathable waterproof sheet 6. The first cover 4 extends along the side surface 21 of the pole body 2. The first cover 4 is plate-shaped. The edge of the first cover 4 overlaps with the edge of the opening 31. The size and shape of the first cover 4 are not limited as long as it can cover the entire opening 31. In this embodiment, the first cover 4 is substantially rectangular and larger than the opening 31. The first cover 4 has a plurality of through holes 41. The plurality of through holes 41 are positioned to overlap with the opening 31. The plurality of through holes 41 are connected to the opening 31. Ultrasonic waves from the ultrasonic sensor S can pass through the plurality of through holes 41. The shape of the through holes 41 is not limited. For example, the through holes 41 may be slits extending in the vertical direction.

[0025] Examples of materials for the first cover 4 include metals and resins. Examples of metals include iron and stainless steel. Examples of resins include polyethylene terephthalate, acrylic resin, polyvinyl chloride and polycarbonate.

[0026] (4) Gasket The packing 5 seals the gap between the side surface 21 of the pole body 2 and the first cover 4. The packing 5 is positioned at the edge of the opening 31. The packing 5 surrounds the opening 31. In this embodiment, the packing 5 has a frame shape. The shape of the packing 5 is not limited. The packing 5 is positioned at the edge of the opening 31 between the side surface 21 of the pole body 2 and the first cover 4. The packing 5 is made of rubber or resin.

[0027] (5) Breathable waterproof sheet The breathable waterproof sheet 6 is placed between the first cover 4 and the second cover 7. The breathable waterproof sheet 6 closes all of the multiple through holes 41 in the first cover 4. As a result, the breathable waterproof sheet 6, together with the first cover 4, closes the opening 31. The breathable waterproof sheet 6 allows gas (water vapor) to pass through but not liquid (water). Therefore, ultrasonic waves from the ultrasonic sensor S pass through the breathable waterproof sheet 6, while rainwater does not. This allows ultrasonic waves from the ultrasonic sensor S to be transmitted to the outside of the housing 3 through the opening 31, while preventing rainwater from entering the housing 3 through the opening 31. The thickness of the breathable waterproof sheet 6 is not limited as long as it can allow ultrasonic waves from the ultrasonic sensor S to pass through.

[0028] (6) Second cover The second cover 7 covers the breathable waterproof sheet 6. The second cover 7 protects the breathable waterproof sheet 6. The second cover 7 overlaps with the breathable waterproof sheet 6 and the first cover 4. In this embodiment, the second cover 7 is screwed to the pole body 2 together with the first cover 4, the packing 5 and the breathable waterproof sheet 6. The second cover 7 has a plurality of through holes 71. The plurality of through holes 71 are positioned to overlap with the opening 31. At least a portion of the through holes 71 overlaps with the through holes 41 of the first cover 4. Ultrasonic waves from the ultrasonic sensor S can pass through the plurality of through holes 71. The shape of the through holes 71 is not limited. For example, the through holes 71 may be slits extending in the vertical direction.

[0029] As for the material of the second cover 7, for example, the same material as the material of the first cover 4 described above can be used.

[0030] 2. Effects (1) According to pole 1, as shown in Figure 2, the ultrasonic sensor S can be housed in the housing 3, thereby protecting the ultrasonic sensor S from rainwater and the like.

[0031] Furthermore, since the housing section 3 is provided with an opening 31 through which ultrasonic waves from the ultrasonic sensor S can pass, it is possible to suppress the obstruction of ultrasonic wave emission from the ultrasonic sensor S by the housing section 3.

[0032] Furthermore, the opening 31 of the housing section 3 is closed by a breathable waterproof sheet 6. The breathable waterproof sheet 6 allows gas (water vapor) to pass through but does not allow liquid (water) to pass through.

[0033] Therefore, ultrasonic waves from the ultrasonic sensor S pass through the breathable waterproof sheet 6, while rainwater does not pass through the breathable waterproof sheet 6.

[0034] This allows ultrasonic waves from the ultrasonic sensor S to be transmitted to the outside of the housing 3 through the opening 31, while suppressing rainwater from entering the housing 3 through the opening 31.

[0035] As a result, the ultrasonic sensor S can be protected from rainwater while suppressing interference with the emission of ultrasonic waves from the ultrasonic sensor S.

[0036] (2) According to pole 1, as shown in Figure 2, the breathable waterproof sheet 6 is placed between the first cover 4 and the second cover 7.

[0037] Therefore, the first cover 4 and the second cover 7 can protect the breathable waterproof sheet 6.

[0038] As a result, it is possible to prevent the breathable waterproof sheet 6 from tearing and rainwater from entering the storage area 3.

[0039] (3) According to pole 1, as shown in Figure 2, the housing section 3 is located inside the pole body 2.

[0040] Therefore, the ultrasonic sensor S can be housed in the space inside the pole body 2. [Explanation of symbols]
