Description

  The present invention relates to a sewage basin and a temporary toilet system, and more particularly to, for example, a sewage basin and a temporary toilet system including the sewage basin, which are used in a temporary toilet system used as a drainage system for a temporary toilet.

  In recent years, a temporary toilet system used as a drainage system for temporary toilets has been installed in advance by attaching toilets to schools and parks that will be evacuation places when a disaster such as an earthquake occurs. Plans are underway.

  For example, Patent Literature 1 discloses an example of a conventional temporary toilet system. The temporary toilet system of Patent Literature 1 includes a plurality of manholes (sewage basins) and a first drain pipe connecting them. This manhole has a connection part (lateral pipe part) connected to the first connection pipe, and a rubber ring socket formed at the top. A vertical tube having been subjected to length adjustment and chamfering is joined to the rubber ring receiving port by a rubber ring.

  A tank (drainage storage tank) is connected to the downstream side of the first drainage pipe, and this tank is connected to the sewage main pipe via the second drainage pipe. A connection pipe for detachably connecting the first drain pipe and the second drain pipe is provided inside the tank, and when the sewage main pipe is usable, the first drain pipe is connected to the first drain pipe via the connection pipe. By communicating with the second drain pipe, drain water is discharged to the sewer main pipe. On the other hand, when the sewage main pipe cannot be used, the drainage is discharged into the tank and temporarily stored by removing the connecting pipe from the first drain pipe and the second drain pipe.

JP 2014-293 A

  Although the construction plan of the temporary toilet system as described above is progressing, the absolute number of temporary toilets that can be used at the time of disaster is not enough at present. Therefore, there is a demand to install a temporary toilet system by effectively using not only limited places such as schools and parks, but also empty spaces (such as gaps between buildings) in residential lands such as hotels, stores, housing complexes, and condominiums. There is.

  Here, in consideration of the labor and cost of the construction, it is preferable that the burial depth of the drainage pipe is made shallow as long as it satisfies the piping regulation stipulated by the regulations. However, the technique of Patent Document 1 is intended for a case where the cover of the drain pipe is 500 mm or more, and does not consider that the cover of the drain pipe is shallowly buried about 250 to 500 mm.

  Further, in the technique of Patent Document 1, it is necessary to connect a vertical pipe to a rubber ring receiving port. For this work, a cutting operation for cutting the vertical pipe to a desired length and a rubber ring joint are appropriately performed. This involves labor for chamfering the ends of the vertical pipes and connecting the rubber rings to the vertical pipes.

  Furthermore, since there is a case where it is not possible to secure space for installing a drainage storage tank in empty space in residential land, a temporary toilet system directly connected to a public basin that directly drains from a drain pipe to a public basin without a drainage storage tank is provided. It may be desirable.

  Therefore, it is a primary object of the present invention to provide a new sewage basin and temporary toilet system.

  Another object of the present invention is to provide a sewage basin and a temporary toilet system including the same, which can construct a temporary toilet system in which a drain pipe is buried shallowly and can be easily constructed.

That is, the protruding length of the riser pipe portion can be adjusted within 100 mm by cutting. Further, a protective lid is provided above the sewage basin, and the height of the protective lid is 150 mm, and the protective lid is installed so that a rising pipe portion of the sewage basin is located below. Therefore, by setting the lowermost position of the cuttable portion of the rising pipe portion to a height position of at most 100 mm from the zenith position of the horizontal pipe portion, the horizontal pipe portion of the wastewater basin has an earth covering of 250 mm. It can also be connected to shallow buried drain pipes.

  According to the first invention, since the cutable portion is provided in the rising pipe portion of the sewage basin, the operation of adjusting the axial length of the rising pipe portion becomes easy. In addition, since the lowest position of the severable part is the height position up to 100 mm at the longest from the zenith position of the horizontal pipe part, the wastewater basin is appropriately connected to the shallow buried drain pipe with 250 mm of earth covering become able to. Therefore, a temporary toilet system in which the drainage pipe is buried shallowly can be easily constructed, and the number of places where the temporary toilet can be installed can be increased.

The sewage basin has a cuttable portion whose position is set to a height of at most 100 mm from the zenith position of the horizontal pipe portion, and the cutoff portion is cut at a desired position, so that the axial direction of the rising pipe portion is reduced. This is a temporary toilet system that is buried underground with its length adjusted.

  In the second invention, the temporary toilet system is constructed in advance in a residential area such as an apartment complex or an apartment, and is used as a drainage facility for the temporary toilet. The temporary toilet system is provided in a plurality of synthetic resin sewage basins, a drainage pipe with ribs connecting the plurality of sewage basins and the public basin, and a drainage pipe with ribs between the most downstream sewage basin and the public basin. Equipped with a height adjustment basin and the like. The sewage basin includes a horizontal pipe portion having a plurality of ribs formed on an outer peripheral surface thereof, and a rising pipe portion integrally formed on the top of the horizontal pipe portion. The riser tube has a cuttable portion whose lowermost position is located at a height of at most 100 mm from the zenith position of the horizontal tube. That is, the protruding length of the rising pipe portion can be adjusted within 100 mm by cutting. Then, the sewage basin is buried in the ground with the length of the rising pipe portion adjusted by cutting the cuttable portion at a desired position.

  According to the second aspect, as in the first aspect, since the cut-off portion is provided in the riser section of the wastewater basin, the work of adjusting the axial length of the riser section becomes easier. In addition, since the lowest position of the severable part is the height position up to 100 mm at the longest from the zenith position of the horizontal pipe part, the wastewater basin is appropriately connected to the shallow buried drain pipe with 250 mm of earth covering become able to.

It is a front view showing other examples of a filthy water basin. It is sectional drawing which shows the wastewater basin of FIG.

  Referring to FIG. 1 and FIG. 2, a temporary toilet system 10 (hereinafter, simply referred to as “system 10”) according to an embodiment of the present invention includes a plurality of sewage basins 12, drain pipes 14, and height adjustment basins 16. It is installed in advance in an empty space (a gap between buildings, etc.) in residential land such as a hotel, a store, an apartment complex, and an apartment. Then, in the event of a disaster, the toilet 100 and the temporary shed 102 are attached to predetermined positions to be used as drainage equipment for temporary toilets.

  As will be described in detail later, the system 10 is a temporary toilet system directly connected to a public basin that directly drains water from the drainage pipe 14 to the public basin 104 (and the sewer main pipe 106) without providing a drainage storage tank. In addition, the burial of the drain pipe 14 (burying depth up to the zenith) is a shallow burial of about 250 to 500 mm. Hereinafter, the configuration of the system 10 will be described.

  As shown in FIGS. 1 and 2, the plurality of sewage basins 12 are buried in the ground corresponding to a predetermined installation position of the toilet 100. In this embodiment, five wastewater basins 12 are arranged in a straight line, for example, every 1500 mm. The specific configuration of the wastewater basin 12 will be described later.

  The drain pipe 14 connects the sewage basins 12 and is disposed at a predetermined downward slope of, for example, 18 mm / 1000 mm. The drainage pipe 14 is a ribbed pipe having a plurality of ribs 14a formed on an outer peripheral surface thereof (ribbed drainage pipe), and is formed of a synthetic resin such as hard vinyl chloride. Each of the ribs 14a is formed in an annular shape and arranged so as to be arranged at predetermined intervals in the axial direction of the drain pipe 14. The inner diameter of the drain pipe 14 is, for example, 150 mm. In this embodiment, the overburden of the drain pipe 14 is approximately 250 mm at the most upstream portion (the portion connected to the water supply tank 18), and is approximately 385 mm at the portion connected to the most downstream sewage basin 12. It is about 800 mm in the downstream part (connection part with the public measure 104).

  The downstream end of the drain pipe 14 is connected to a public basin 104 connected to the sewer main pipe 106. That is, the drain pipe 14 connects the plurality of wastewater basins 12 and the public basin 104. The drain pipe 14 is provided with a height-adjusting tub 16, which will be described later, in a pipe portion between the most downstream sewage pit 12 and the public pit 104.

  On the other hand, a water supply tank 18 for feeding cleaning water into the drain pipe 14 is provided at an upstream end of the drain pipe 14. The water supply tank 18 is formed of a synthetic resin such as hard vinyl chloride into a bottomed cylindrical shape, and an inner lid is detachably attached to an upper end opening thereof. An outlet 18a connected to the upstream end of the drain pipe 14 is formed at the lower end of the side wall of the water supply tank 18, and a gate valve (not shown) is provided at the outlet 18a. The water supplied into the water supply tank 18 is flown as washing water into the drain pipe 14 from the outlet 18a by opening the gate valve. However, the gate valve does not necessarily need to be provided, and the water supplied to the water supply tank 18 may be supplied to the drain pipe 14 from the outlet 18a as it is. Further, the shape and the like of the water supply tank 18 can be appropriately changed.

  A pedestal 50 made of synthetic resin is embedded so as to surround each of the upper ends of the sewage basin 12, the height adjustment basin 16 and the water supply tank 18. On this pedestal 50, a protective lid composed of a receiving frame 52, an iron lid 54 and the like is placed. That is, a substantially cylindrical iron receiving frame 52 is placed on the pedestal 50, and an iron lid 54 is detachably provided at an upper end opening of the receiving frame 52. The upper surface of the iron lid 54 faces the ground surface. By removing the iron lid 54, each of the upper ends of the sewage basin 12, the height adjustment basin 16 and the water supply tank 18 is exposed to the outside. The height (vertical length) of the protective lid including the receiving frame 52 and the iron lid 54 is, for example, 150 mm.

  Next, the configuration of the wastewater basin 12 will be specifically described. As shown in FIGS. 3 and 4, the wastewater basin 12 includes a horizontal pipe portion 20 and a rising pipe portion 22, and is formed of a synthetic resin such as hard vinyl chloride.

  The horizontal pipe portion 20 of the wastewater basin 12 is formed so as to extend linearly in the horizontal direction. A plurality of ribs 24 extending in the circumferential direction are formed on the outer peripheral surface of the horizontal tube portion 20 so as to be arranged at predetermined intervals in the axial direction. In addition, two legs 26, which are rectangular frame-shaped projections, are provided at the bottom of the horizontal tube portion 20 at the central portion in the axial direction. Further, at one end of the horizontal pipe portion 20, an enlarged-diameter receiving port 28 as an inflow-side pipe connection portion (inflow port) is formed, and at the other end of the horizontal pipe portion 20, an outflow-side pipe connection portion is provided. A spout 30 which is a part (outflow port) is formed. A rubber ring 32 is mounted on the outer peripheral surface on the distal end side of the spigot 30. In addition, a mark line 34 is provided on the outer peripheral surface on the base end side of the spigot 30 as a guide for the insertion depth of the spigot 30. The drainage pipe 14 is rubber-joined to each of the enlarged-diameter receiving port 28 and the spigot 30, and the horizontal pipe section 20 forms a drainage pipe for flowing sewage together with the drainage pipe 14.

  The rising pipe part 22 of the sewage basin 12 is formed integrally with the horizontal pipe part 20 so as to extend upward from the top of the axial center part of the horizontal pipe part 20. The inner diameter of the riser section 22 is, for example, 300 mm.

  Each of such sewage basins 12 is buried under the protective cover including the iron cover 72 and the receiving frame 74, that is, such that the upper end of the rising pipe portion 22 is at a height of, for example, 150 mm from the ground surface. Is done. On the other hand, the burying depth of the horizontal pipe 20 is deeper toward the downstream side because the drain pipe 14 connected to the horizontal pipe 20 is disposed at a predetermined downward slope. That is, the height dimension of the sewage basin 12 varies depending on the arrangement position (the burying depth of the horizontal pipe portion 20).

  Regarding this point, in the sewage basin used in the conventional temporary toilet system, a rubber ring socket is formed at the top of the sewage basin, and a vertical pipe whose length is adjusted to this rubber ring socket is bonded to the rubber ring. This has been addressed by adjusting the axial length of the riser section. However, the work of connecting the vertical pipe to the rubber ring receiving port of the sewage basin includes cutting work for cutting the vertical pipe to a desired length, chamfering work of the end of the vertical pipe for appropriately performing rubber ring joining, In addition, the connecting operation for joining the rubber ring receiving port and the vertical pipe to the rubber ring is included, which is troublesome. Further, in the conventional sewage basin, the axial length of the standing pipe portion is inevitably increased by an amount corresponding to the provision of the rubber ring receiving port and the rubber ring joining. For this reason, the embedding depth of the horizontal pipe portion (connection portion with the drainage pipe) cannot be reduced, and connection to a shallowly buried drainage pipe with an earth covering of about 250 to 500 mm has been impossible. .

  Therefore, in this embodiment, a rising pipe portion 22 having a predetermined length (an assumed maximum length) is provided integrally with the horizontal pipe portion 20, and the rising pipe portion 22 is cut at a desired position. Thus, the cuttable portion 22a whose length can be adjusted can be formed. Thus, when adjusting the height of the sewage basin 12 (the axial length of the riser pipe portion 22), it is sufficient to cut the cuttable portion 22a at a desired position. Becomes easier.

  The lowermost position 22b of the severable portion 22a is a height position from the zenith position 20a of the horizontal tube portion 20 to at most 100 mm. That is, the height difference h between the lowermost position 22b of the cuttable portion 22a and the zenith position 20a of the horizontal tube portion 20 is within 100 mm, and the protruding length of the rising tube portion 22 (the zenith position of the horizontal tube portion 20). The length from 20a to the upper end of the riser section 22) can be adjusted within 100 mm. Here, the height of the protective lid is 150 mm, and the protective lid is installed so that the rising pipe portion 22 of the sewage basin 12 is located below it. Therefore, by setting the lowermost position 22b of the cuttable portion 22a of the riser tube portion 22 to a height position of at most 100 mm from the zenith position 20a of the horizontal tube portion 20, a shallow burial having an earth cover of 250mm is provided. The wastewater basin 12 can also be connected to the drain pipe 14.

  Here, the cuttable portion 22a is a portion of the riser tube portion 22 that is easily cut and formed in a plain tubular shape (straight tubular shape) and does not impair the function of the wastewater basin 12 even when cut. .

  Specifically, when manufacturing the wastewater basin 12 of this embodiment, the horizontal pipe portion 20 and the base end portion of the short cylindrical rising pipe portion 22 are integrally formed by injection molding. Then, the horizontal tube portion 20 and the riser tube portion 22 are integrated with the base end portion by bonding and joining a single receiving straight tube having an adhesive receiving port formed at one end. The protruding length of the rising pipe portion 22 is, for example, 375 mm. In this embodiment, the plain tubular portion excluding the adhesive joint portion is the cuttable portion 22a, and the height difference h between the lowermost position 22b of the cuttable portion 22a and the zenith position 20a of the horizontal pipe portion 20 is 85 mm. It is.

  Although not shown, a mark indicating the range of the cuttable portion 22a or the lowest position 22b may be provided on the riser tube portion 22 so that the operator can easily identify the cuttable portion 22a. it can.

  As shown in FIGS. 1 and 5, the sewage basin 12 as described above cuts the cuttable portion 22a at a desired position in accordance with the burial depth of the drainage pipe 14 and the horizontal pipe section 20, thereby forming a rising pipe. It is buried in the ground with the axial length of the part 22 adjusted. Further, an inner lid 56 made of a synthetic resin is attached to the upper end opening of the rising pipe portion 22 after the cutting.

  Further, as described above, the drainage pipe 14 is rubber-joined to each of the enlarged-diameter receiving port 28 and the spigot 30 of the horizontal pipe section 20. At this time, ribs 14a and 24 are formed on the outer peripheral surfaces of the drain pipe 14 and the horizontal pipe section 20 of the wastewater basin 12, and the drain pipe formed by the drain pipe 14 and the horizontal pipe section 20 has high strength. This drainage line can be backfilled with crushed stone (not shown). By backfilling with crushed stone, liquefaction of the surrounding ground during an earthquake can be suppressed.

  Next, the configuration of the height adjustment box 16 will be described. As shown in FIGS. 1 and 6, the height adjusting tub 16 is formed with a stepped portion in the drain pipe 14 so that the drain pipe 14 and the public tub 104 can be properly connected to each other. For adjusting the burying depth, and is made of synthetic resin such as hard vinyl chloride. The height adjustment box 16 is also used as a check box.

  Specifically, the height adjustment box 16 includes a box body 60 formed in a bottomed cylindrical shape. The inside diameter of the box body 60 is, for example, 300 mm. An inner lid 56 is detachably attached to the upper end opening of the basin body 60. An outlet 62 connected to the drain pipe 14 is provided at the lower end of the downstream side wall of the basin body 60, and an inlet 64 connected to the drain pipe 14 is provided on the upstream side wall of the basin body 60. Is provided. The inflow port 64 is formed by a clap-shaped joint, and the installation height of the inflow port 64 with respect to the box body 60 can be changed. When the inlet 64 is provided in the box body 60, the side wall of the box body 60 is pierced at a desired height position, and the inlet 64 is adhesively bonded to the perforated portion.

  By providing such a height-adjusting basin 16 between the most downstream sewage basin 12 and the public basin 104, even if the drainage pipe 14 is buried shallowly, the drainage pipe 14 does not require a large space. And the public square 104 can be properly connected. That is, the height of the drain pipe 14 can be adjusted by using two universal joints or the like and providing an inclined portion of the drain pipe 14 with a slope larger than a predetermined slope (18 mm / 1000 mm). Since this requires a certain distance, a large space is required. On the other hand, by using the height adjustment box 16, space can be saved.

  By installing the above system 10 in the ground of an evacuation site before a disaster occurs, a temporary toilet can be quickly and easily installed when a disaster occurs. .

  When the system 10 is used as a drainage system for a temporary toilet, first, equipment such as the toilet bowl 100 and the temporary shed 102 is carried out from a storage (not shown) to the ground near the system 10. Next, the iron cover 54 provided above each sewage basin 12 and the inner cover 56 attached to the riser pipe section 22 are removed, and the toilet 100 is installed above each sewage basin 12. In addition, a temporary shed 102 is installed so as to surround each toilet 100. Thereby, the temporary toilet can be used.

  Cleaning water is supplied into the water supply tank 18 using a water supply pump (not shown) or the like. As a water supply source for supplying the cleaning water into the water supply tank 18, a water tank or a well in which rainwater, tap water, or the like is stored in advance may be used. For example, various rainwater storage tanks (refer to http://www.kubota-ci.co.jp/products/sewage/rain.html) manufactured and sold by the applicant of the present application are used for the piping route of the drain pipe 14. It is preferable that the rainwater stored in the rainwater storage tank be supplied adjacent to the water supply tank 18.

  When the temporary toilet is used and the waste discharged from each toilet 100 into the wastewater basin 12 is accumulated, the gate valve of the water supply tank 18 is opened, and the drainage pipe 14 is opened from the outlet 18 a of the water supply tank 18. A predetermined amount of washing water is allowed to flow in. The timing of opening the gate valve of the water supply tank 18 and the amount of the cleaning water fed from the water supply tank 18 are appropriately adjusted so that the waste collected in each sewage basin 12 can be swept with a relatively small amount of the cleaning water. I do.

  The cleaning water supplied from the water supply tank 18 to the drainage pipe 14 flows down the drainage pipe 14 and the horizontal pipe part 20 of the wastewater basin 12 at a predetermined speed, while washing away the dirt accumulated in each wastewater basin 12, It is guided to the public square 104 and discharged from the public square 104 to the sewage main pipe 106. Thereby, the temporary toilet can be used hygienically.

  As described above, according to this embodiment, since the cuttable portion 22a is provided in the riser pipe portion 22 of the wastewater basin 12, the work of adjusting the axial length of the riser pipe portion 22 becomes easy. In addition, since the lowermost position 22b of the cuttable portion 22a is set to a height of at most 100 mm from the zenith position 20a of the horizontal tube portion 20, the drainage pipe 14 having a shallow burial having an earth covering of 250mm is also contaminated. The squares 12 can be connected appropriately. Therefore, a temporary toilet system in which the drain pipe 14 is buried shallowly can be easily constructed, and the number of places where the temporary toilet can be installed can be increased.

  In addition, since the height adjustment basin 16 is provided for the drainage pipe 14 between the most downstream sewage basin 12 and the public basin 104, even if the drainage pipe 14 is buried shallowly, a large space is not required. The drain pipe 14 and the public measure 104 can be appropriately connected.

  In the above-described embodiment, the inner lid 56 is provided in the riser pipe portion 22 of the sewage basin 12, and the iron lid 54 (protective lid) facing the ground surface is provided above the sewage basin 12. The lid 54 can be omitted. For example, as in the embodiment shown in FIG. 7, a substantially disc-shaped synthetic resin lid 80 is attached to the upper end opening of the rising portion 22, and the wastewater basin 12 is buried so that the lid 80 faces the ground surface. You can also. When the toilet 100 is installed above the sewage basin 12 in the event of a disaster, the lid 80 need only be removed. Similarly, the iron cover 54 may be omitted for one or both of the height adjustment box 16 and the water supply tank 18. As described above, by omitting the iron cover 54, the drain pipe 14 can be further buried.

  Further, in the above-described embodiment, the Western toilet 100 is installed above each of the wastewater basins 12, but a Japanese toilet may be used. For example, in the embodiment shown in FIG. 8, an iron pedestal 50 is embedded so as to surround the upper end of the rising portion 22 of the wastewater basin 12. On this pedestal 50, a protective lid composed of a receiving frame 70, an iron lid 72, an inner lid 74 and the like is placed. Specifically, a substantially rectangular cylindrical iron receiving frame 70 is placed on the pedestal 50. The lower end of the receiving frame 70 is formed in a tapered shape, and a substantially short cylindrical lower end opening is formed therein. An iron lid 72 is rotatably provided at the upper end opening of the receiving frame 70 via a hinge, and an inner lid 74 is detachably attached to the lower end opening of the receiving frame 70. The height (length in the vertical direction) of the protective lid including the receiving frame 70, the iron lid 72, and the inner lid 74 is, for example, 150 mm. Note that a lid is not attached to the upper end opening of the rising portion 22 of the wastewater basin 12.

  When the system 10 of the embodiment shown in FIG. 8 is used as a drainage system for a temporary toilet, a temporary shed 102 is installed so as to surround each iron lid 72. In addition, the upper end opening of the receiving frame 70 is opened so that the iron cover 72 is set up, and the inner cover 74 is removed. Thereby, the temporary toilet can be used. That is, in the embodiment shown in FIG. 8, the receiving frame 70 itself is used as a Japanese-style toilet, and the iron cover 72 is used as a gold cover.

  In addition, in the embodiment shown in FIG. 8, not only the receiving frame 70 can be used as it is as a Japanese-style toilet but also a Western-style toilet can be obtained by installing the toilet 100 as shown in FIG. In addition, it is not necessary to use all Western styles or Japanese styles, and for example, Western styles and Japanese styles may be installed in half each.

  Further, in the above-described embodiment, the height adjusting box 16 provided with the outlet 62 at the lower end of the side wall of the box body 60 is used, but the configuration of the height adjusting box 16 can be changed as appropriate. For example, the height adjustment box 16 may be a drop box provided with an outlet on its bottom wall. The use of the height adjustment box 16 as a drop box is effective when the head (difference in height) between the drain pipe 14 and the connection part of the public box 104 is large, for example, when the head is 600 mm or more. In addition, it is not necessary that the installation height of the inflow port 64 of the height-adjusting cell 16 with respect to the cell main body 60 can be changed.

  Furthermore, in the above-described embodiment, the horizontal pipe portion 20 and the riser pipe portion 22 of the wastewater basin 12 are integrated using adhesive bonding, but the manufacturing method and the specific configuration of the wastewater basin 12 can be appropriately changed. .

  For example, as shown in FIGS. 9 and 10, the entire wastewater basin 12 can be integrally formed by injection molding. In the wastewater basin 12 of the embodiment shown in FIG. 9, the height difference h between the lowermost position 22 b of the cuttable portion 22 a and the zenith position 20 a of the horizontal pipe portion 20 is 20 mm. As described above, since the lowermost position 22b of the cuttable portion 22a can be set lower by integrally molding the wastewater basin 12 by injection molding, the drainage pipe 14 can be further buried shallowly. it can.

  In addition, the horizontal pipe portion 20 of the wastewater basin 12 can be formed in a curved tubular shape, or can be formed in a bent tubular shape bent at an angle such as 90 ° or 120 °. Further, the horizontal pipe portion 20 of the sewage basin 12 may be formed in a confluent tubular shape provided with a plurality of inflow ports (diameter expansion ports 28).

  Further, in the above-described embodiment, the five sewage basins 12 are linearly arranged at equal intervals, but this is merely an example, and the number and arrangement of the sewage basins 12 are determined by the size of the evacuation area. It can be changed appropriately according to the situation. For example, the wastewater basins 12 may be arranged in a curved line. Further, the wastewater basins 12 can be arranged in an L shape, a V shape, a Y shape, or the like.

  In the above-described embodiment, the system 10 is installed in an empty space in a residential area such as an apartment, but the system 10 can be installed in other places such as a school or a park.

  Note that the specific numerical values such as the dimensions described above are merely examples, and can be appropriately changed as necessary according to the specifications of the product.
