Technical Field

[0001] The present invention relates to a bottom plate for a manhole toilet suitable for a manhole toilet and a manhole toilet provided with the bottom plate.

Background Art

[0002] Regarding a simple toilet (temporary toilet) that is indispensable in the event of a disaster or the like, conventionally, the mainstream mode has been to transport and install a simple toilet equipped with a toilet bowl to an evacuation site. However, in recent years, in schools, parks, etc. that serve as evacuation sites, manholes connected to sewer pipelines and large-capacity storage tanks have been installed in advance, and at the time of a disaster or the like, a simple toilet facility is installed in the manhole to make it available. The maintenance of manhole toilets is progressing. Along with the spread of these manhole toilets, various prior arts related to simple toilets have been disclosed (see, for example, Patent Documents 1 to Patent Documents 3).

[0003] The simple toilet disclosed in Patent Document 1 is composed of a disassemblable and assemblable floor panel, a frame, and a covering curtain. The floor panel has a feces dropping hole in the central part and frame mounting parts in the corner parts. The frame has a plurality of rod members that can be connected to the frame mounting parts and are assemblable with the disassembled and ceiling parts in a reverse U-shaped curved shape when viewed from the front. The covering curtain is made of a foldable flexible member, has a bottom surface opening shape that can form a toilet space together with the frame and the floor panel, and the front part is formed of a fixed surface part and a door-shaped surface part that can be opened and closed with a fastener part arranged from the center of the upper edge of the same surface part to one corner of the lower edge of the same surface part as a boundary.

[0004] According to the simple toilet disclosed in Patent Document 1, it is described that it is lightweight, compact, easy to store and transport, can be easily and quickly assembled by a layperson in an emergency, can be operated for entry and exit with one hand after installation, and is useful for emergency use.

[0005] Furthermore, Patent Document 2 discloses a temporary toilet that is constructed by combining a sewer manhole and a toilet bowl, characterized in that a floorboard with a toilet bowl installed in a toilet bowl hole drilled in the center is placed on the lid receiving frame after the iron cover of the sewer manhole has been removed, and a temporary hut having an opening and closing door is erected around the floorboard.

[0006] According to the temporary toilet disclosed in Patent Document 2, the toilet is constructed by attaching a floor plate with a toilet bowl to the opening of a sewer manhole, and it is stated that it can be easily installed and used after the iron cover of the sewer manhole is removed.

[0007] Furthermore, Patent Document 3 discloses a temporary toilet system that is used as a temporary toilet by attaching a temporary hut that forms a private room space around the toilet bowl when in use, comprising a plurality of vertical pipe members buried in the ground at a predetermined installation location for the toilet bowl, a drain pipe connecting the lower ends of the vertical pipe members, a vertical pipe cover provided so as to be substantially flush with the ground surface and covering the upper part of the vertical pipe members, and fixing support points installed around the vertical pipe members to which ropes or wires for fixing the temporary hut are connected, wherein the temporary hut is a box-shaped hut with a lockable door, and the fixing support points are pre-buried in the ground so that their upper ends are located below the ground surface.

[0008] According to the temporary toilet system disclosed in Patent Document 3, since fixing support points are permanently installed, the temporary hut can be easily and firmly fixed, making it easier to install the temporary toilet and shortening the installation time for the temporary toilet. [Prior art documents] [Patent Documents]

[0009] [Patent Document 1] Japanese Patent Application Publication No. 9-75259 [Patent Document 2] Japanese Patent Application Publication No. 9-285424 [Patent Document 3] Patent No. 7336829 [Overview of the Initiative] [Problems that the invention aims to solve]

[0010] The portable toilet disclosed in Patent Document 1 and the temporary toilet disclosed in Patent Document 2 appear to be relatively easy to install. However, the portable toilet disclosed in Patent Document 1 does not have a fixed floor panel, so while stability is increased when the user stands on the floor panel during use, it appears to lack stability when not in use. In particular, the cover made of flexible material is vulnerable to wind and rain, so even in emergency situations, it appears to be very stressful for the user.

[0011] Furthermore, the floorboards for the temporary toilets disclosed in Patent Document 2 are made of steel plates or wooden floorboards, and the structure involves installing the floorboards in the manhole and then fixing them to the ground with anchors. While steel plate floorboards are thought to offer improved stability, fixing them to the ground with anchors is not easy, and the surface is thought to become very slippery when wet. On the other hand, while wooden floorboards are lightweight and easy to handle, cleaning the surface when it gets dirty is difficult, and there is a possibility of problems with dirt and odor.

[0012] Furthermore, while the temporary toilet system disclosed in Patent Document 3 is thought to be easy to install, the fixing members used to secure the temporary hut generally get in the way. Therefore, there is a need for a manhole toilet that is highly stable, hygienic, and easy to install without such fixing members.

[0013] Therefore, in view of the above-mentioned problems, the inventors of this application have diligently conducted research to provide a manhole toilet base plate and a manhole toilet equipped with this base plate, which can significantly improve the stability of the manhole toilet during installation and is also highly hygienic and versatile. As a result, they have arrived at the present invention. [Means for solving the problem]

[0014] In other words, the present invention is a bottom plate for a manhole toilet that forms the floor surface of a manhole toilet installed in a manhole, comprising at least a perforated metal having a plurality of small holes formed therein, The perforated metal comprises an opening formed at a predetermined position in the perforated metal, a connecting pipe projecting downward from near the opening edge of the opening on the lower surface side of the perforated metal, and a reinforcing member disposed on the lower surface side to form a gap between the installation surface of the perforated metal and the perforated metal, wherein the connecting pipe is provided with fixing means for fixing the connecting pipe to the manhole, the connecting pipe is inserted into the manhole, and the inserted connecting pipe is fixed to the manhole by the fixing means.

[0015] Furthermore, the bottom plate for manhole toilets according to the present invention is characterized in that the height from the installation surface to the upper surface of the perforated metal is 20 mm or less.

[0016] Furthermore, the bottom plate for a manhole toilet of the present invention is characterized in that a support plate is provided around the periphery of the perforated metal, except for the position where the door member for the manhole toilet is provided, and a clamping piece is erected opposite the support plate, with a predetermined gap between them.

[0017] Furthermore, the present invention relates to a manhole toilet installed in a manhole, comprising at least a manhole toilet base plate comprising: perforated metal; an opening formed at a predetermined position in the perforated metal; a connecting pipe projecting downward from near the edge of the opening on the lower surface side of the perforated metal; and a reinforcing member disposed on the lower surface side of the perforated metal and forming a gap between the installation surface of the perforated metal and the perforated metal; a wall member erected along the periphery of the manhole toilet base plate; a door member installed on a part of the wall member; a roof member disposed to cover the upper opening formed by the wall member; and a toilet bowl installed in the opening, wherein the connecting pipe relating to the manhole toilet base plate is provided with fixing means for fixing the connecting pipe to the manhole, and the manhole toilet base plate is fixed to the manhole by inserting the connecting pipe into the manhole and fixing the inserted connecting pipe to the manhole by the fixing means.

[0018] Furthermore, in the manhole toilet of the present invention, a support plate is provided around the periphery of the perforated metal, except at the position where the door member is installed, and a clamping piece is erected at a position opposite the support plate with a predetermined gap between it and the support plate, the wall member is inserted into the gap, and the wall member is fixed in a state where it is clamped between the support plate and the clamping piece. [Effects of the Invention]

[0019] The manhole toilet base plate of the present invention can be easily installed by simply inserting the connecting pipe provided on the base plate into an existing manhole and securing it with fixing means. Furthermore, because it is mainly made of perforated metal, it has a moderate weight and high stability, making it easy to prevent the manhole toilet base plate from shifting position. Thus, the instability that occurs when installing a manhole toilet can be eliminated.

[0020] In addition, since the bottom plate for the manhole toilet of the present invention is mainly formed of punching metal, when the upper surface of the punching metal is soiled, it can be easily cleaned, which is very hygienic. Also, even after cleaning or on rainy days, the floor is not slippery, and the safety during toilet use is improved. Furthermore, since a slight gap is formed on the lower surface side of the punching metal by a reinforcing member, the cleaning water when cleaning the upper surface of the punching metal falls to the lower surface side of the punching metal and can finally be discharged outside the bottom plate for the manhole toilet, further improving the hygiene aspect.

[0021] In addition, in the bottom plate for the manhole toilet of the present invention, by setting the height from the installation surface to the upper surface of the punching metal to 20 mm or less, a barrier-free manhole toilet can be provided.

[0022] Furthermore, in the bottom plate for the manhole toilet of the present invention, along the periphery of the punching metal, a support plate is provided around except for the position where the door member related to the manhole toilet is arranged, and at a position opposite to the support plate, a clamping piece is erected with a predetermined gap between it and the support plate. As a result, it is easy to install the wall surface member on the bottom plate for the manhole toilet of the present invention, and the installation work of the manhole toilet becomes very easy.

[0023] In addition, according to the manhole toilet of the present invention, since it has a configuration including the above-mentioned bottom plate for the manhole toilet, a manhole toilet with excellent stability, hygiene, and high safety can be easily provided.

[0024] Also, in the manhole toilet of the present invention, along the periphery of the punching metal, a support plate is provided around except for the position where the door member is arranged, and at a position opposite to the support plate, a clamping piece is erected with a predetermined gap between it and the support plate. By inserting the wall surface member into this gap and fixing it in a state of being clamped by the support plate and the clamping piece, the installation work of the manhole toilet becomes very easy.

[Figure 4] A manhole toilet according to one embodiment of the present invention, wherein (a) is a front view, (b) is a left side view, and (c) is a rear view. [Modes for carrying out the invention]

[0026] The embodiments of the manhole toilet base plate and manhole toilet of the present invention will be described in detail below with reference to the drawings. Figure 1 is an exploded perspective view of a manhole toilet 1 including a manhole toilet base plate 10 according to one embodiment of the present invention, Figure 2 is a plan view of the manhole toilet base plate 10 of this embodiment, Figure 3(a) is a cross-sectional view AA of the manhole toilet base plate 10 shown in Figure 2, and Figure 3(b) is a cross-sectional view BB of the manhole toilet base plate 10 shown in Figure 2.

[0027] As shown in Figures 1 to 3, the manhole toilet bottom plate 10 of this embodiment is a manhole toilet bottom plate that forms the floor surface of a manhole toilet 1 installed in a manhole M, and comprises at least a perforated metal 12 with a plurality of small holes formed therein, an opening 14 formed at a predetermined position in the perforated metal 12, a connecting pipe 16 that protrudes downward from near the opening edge 14a of the opening 14 on the lower surface 12a side of the perforated metal 12, and a reinforcing member 18 disposed on the lower surface 12a side of the perforated metal 12 and forming a gap C between the perforated metal 12 and the installation surface F of the perforated metal 12, such as the ground or the manhole toilet installation location.

[0028] The perforated metal 12 in the manhole toilet base plate 10 of this embodiment is made of stainless steel. Although it is slightly heavier than resin, it is very lighter than iron plate, making installation relatively easy. Furthermore, the moderate weight provides excellent stability to the manhole toilet base plate 10 when it is installed, including the perforated metal 12.

[0029] The opening 14 in the manhole toilet base plate 10 of this embodiment is formed approximately in the center of the perforated metal 12, and a connecting pipe 16 is provided projecting downward from near the opening edge 14a of the opening 14 on the lower surface 12a side of the perforated metal 12. The diameters of the opening 14 and the connecting pipe 16 are not particularly limited, but it is preferable that the diameter of the opening 14 is smaller than the diameter of the connecting pipe 16. By setting the diameter of the opening 14 to be smaller than the diameter of the connecting pipe 16, the fixing means 20, which will be described later, can be arranged between the opening edge 14a of the opening 14 and the inner circumferential surface of the connecting pipe 16, so that when installing the toilet T in the opening 14 the fixing means 20 does not get in the way and the installation work becomes easier. Furthermore, since the diameter of manholes can be of various sizes, such as 250 mm, 300 mm, and 400 mm, it is preferable to set the diameter of the connecting pipe 16 to less than 250 mm in order to ensure the versatility of the connecting pipe 16 and, by extension, the versatility of the manhole toilet base plate 10 of this embodiment. However, for the connecting pipe 16 related to the base plate 10 for manhole toilets whose installation location has been specified in advance, it is also possible to set the diameter of the connecting pipe 16 to match the diameter of the manhole M at the installation location.

[0030] Furthermore, the connecting pipe 16 for the manhole toilet base plate 10 of this embodiment is equipped with fixing means 20 for fixing the connecting pipe 16 to the manhole M. The form of the fixing means 20 is not particularly limited, but for example, a wing bolt as shown in Figure 2 can be used. By inserting the connecting pipe 16 into the manhole M and, in this embodiment, bringing the tips of the three wing bolts into contact with the inner circumferential surface of the manhole M, the manhole toilet base plate 10 of this embodiment can be fixed to the manhole M via the connecting pipe 16. The length of the wing bolts used as fixing means 20 is appropriately selected according to the diameter of the manhole M.

[0031] Furthermore, on the lower surface 12a side of the perforated metal 12 in the manhole toilet bottom plate 10 of this embodiment, a reinforcing member 18 is provided to form a gap C between the perforated metal 12 and the installation surface F of the perforated metal 12, such as the ground or the location where the manhole toilet is installed. The reinforcing member 18 in this embodiment is a long member with a U-shaped cross-section, and reinforces the perforated metal 12 while securing a gap C on the lower surface 12b side of the perforated metal 12.

[0032] At least, with the manhole toilet base plate 10 of this embodiment having the above configuration, it can be easily installed by simply inserting the connecting pipe 16 of the manhole toilet base plate 10 into the existing manhole M and fixing it with the fixing means 20. Furthermore, because it is mainly made of perforated metal 12, it has a moderate weight and high stability, and displacement of the manhole toilet base plate 10 can be easily prevented. Therefore, instability during the installation of the manhole toilet 1 can be eliminated.

[0033] Furthermore, since the manhole toilet bottom plate 10 of this embodiment is mainly made of perforated metal 12, the upper surface 12a of the perforated metal 12 can be easily cleaned if it becomes dirty, making it very hygienic. In addition, even after cleaning or in rainy weather, the surface is less slippery, improving safety when using the toilet. Moreover, since a small gap C is formed on the lower surface 12b side of the perforated metal 12 by the reinforcing member 18, the cleaning water when cleaning the upper surface 12a of the perforated metal 12 falls to the lower surface 12b side of the perforated metal 12 and can finally be discharged to the outside of the manhole toilet bottom plate 10, further improving hygiene.

[0034] The base plate 10 for the manhole toilet of this embodiment has been described in detail above. Here, it is particularly preferable to set the height from the installation surface F of the base plate 10 to the upper surface 12a of the perforated metal 12 to 20 mm or less. By setting the height from the installation surface F of the base plate 10 to the upper surface 12a of the perforated metal 12 to 20 mm or less, a barrier-free base plate 10 for the manhole toilet and manhole toilet 1 can be provided.

[0035] Furthermore, in the manhole toilet bottom plate 10 of this embodiment, a support plate 22 is provided around the periphery of the perforated metal 12, except for the position where the door member D for the manhole toilet 1 is installed, and a clamping piece 24 is erected opposite the support plate 22, leaving a predetermined gap I between them. Here, the wall member W that constitutes the manhole toilet 1 is inserted into the gap I between the support plate 22 and the clamping piece 24. In other words, because a gap I into which the wall member W can be inserted is formed between the support plate 22 and the clamping piece 24, when assembling the manhole toilet 1, the wall member W can be easily erected by simply inserting the wall member W into the gap I between the support plate 22 and the clamping piece 24.

[0036] Next, a manhole toilet 1 according to one embodiment of the present invention will be described. As shown in Figures 1 and 4, the manhole toilet 1 of this embodiment is installed in a manhole M. It comprises at least the manhole toilet base plate 10 according to the embodiment of the present invention described above, a wall member W erected along the periphery of the manhole toilet base plate 10, a door member D installed on the wall member W, a roof member R disposed to cover the upper opening formed by the wall member W, and a toilet bowl T installed in the opening 14 related to the manhole toilet base plate 10.

[0037] The manhole toilet base plate 10 according to this embodiment of the manhole toilet 1 has the same configuration as the manhole toilet base plate 10 according to the embodiment of the present invention described above. Specifically, it is composed of a perforated metal 12 with a plurality of small holes formed therein, an opening 14 formed at a predetermined position in the perforated metal 12, a connecting pipe 16 projecting downward from near the opening edge 14a of the opening 14 on the lower surface 12b side of the perforated metal 12, and a reinforcing member 18 disposed on the lower surface 12b side of the perforated metal 12 and forming a gap C between the installation surface F of the perforated metal 12 and the perforated metal 12. Furthermore, the connecting pipe 16 according to the manhole toilet base plate 10 is provided with fixing means 20 for fixing the connecting pipe 16 to the manhole M.

[0038] The manhole toilet 1 of this embodiment, having at least the above configuration, can be installed by the following procedure. Specifically, as shown in Figure 1, first the manhole toilet base plate 10 is installed on the installation surface F. More precisely, the connecting pipe 16 provided on the manhole toilet base plate 10 is inserted into the manhole M, and the manhole toilet base plate 10 is fixed to the manhole M via the connecting pipe 16 using the fixing means 20 provided on the connecting pipe 16.

[0039] After fixing the manhole toilet base plate 10 according to this embodiment to the manhole M, wall members W are erected around the periphery of the manhole toilet base plate 10, and a door member D is installed. Furthermore, a roof member R is placed to cover the upper opening formed by the wall members W, and a toilet seat T is installed in the opening 14 formed in the manhole toilet base plate 10, thereby forming the manhole toilet 1 of this embodiment.

[0040] According to the manhole toilet 1 of this embodiment, which has at least the above configuration, the configuration includes the bottom plate 10 for the manhole toilet of this embodiment described above, making it possible to easily provide a manhole toilet 1 that is highly stable, hygienic, and safe.

[0041] In this embodiment of the manhole toilet 1, it is preferable that a support plate 22 is provided around the periphery of the perforated metal 12 relating to the manhole toilet bottom plate 10, except for the position where the door member D is provided, and that a clamping piece 24 is erected opposite the support plate 22, leaving a predetermined gap I between them. In this way, by providing a support plate 22 at a predetermined position along the periphery of the perforated metal 12, and erecting a clamping piece 24 opposite the support plate 22 with a predetermined gap I, the wall member W is inserted into the gap I formed between the support plate 22 and the clamping piece 24, and the wall member W is fixed in a clamped state between the support plate 22 and the clamping piece 24, making the installation of the manhole toilet 1 of this embodiment very easy.

[0042] While it is possible to form the wall surface of the manhole toilet 1 of this embodiment simply by inserting the wall member W into the gap I formed between the support plate 22 and the clamping piece 24, it is more preferable to, for example, as shown in Figures 2 and 3, to place a fixing member 26 on the clamping piece 24, insert the wall member W into the gap I, and then fix the wall member W with this fixing member 26.

[0043] Although embodiments of the manhole toilet base plate and the manhole toilet equipped with this base plate have been described in detail above, these embodiments should not be interpreted as substantially limiting the technical idea of ​​the present invention. For example, in the wall member W of the manhole toilet 1 of this embodiment, it is also possible to make it foldable by a hinge H, as shown in Figure 4. The present invention can be implemented with appropriate improvements, modifications, or additions by those skilled in the art, without departing from its essence, through their ingenuity and creativity.
