[Modes for carrying out the invention]

[0021] Hereinafter, an assembly-type toilet according to an embodiment of the present invention will be described based on the drawings. Figures 1 and 2 show the external appearance of the assembly-type toilet 1 according to this embodiment. In the following, from the perspective of a user (not shown) seated on the assembly-type toilet 1, the front is defined as the front, the back as the rear, the sides as the right and left, and the height direction of the assembly-type toilet as the top and bottom (see Figure 1).

[0022] As shown in Figures 1 and 2, the modular toilet 1 is composed of multiple parts and can be disassembled and assembled. Specifically, the modular toilet 1 is composed of a plate-shaped front member 20, a plate-shaped rear member 30, a plate-shaped right side member 40, a plate-shaped left side member 50, and a plate-shaped toilet seat member 10. The toilet seat member 10 is attached to the upper end 3 of the main body 2, which is formed by combining the front member 20, rear member 30, right side member 40, and left side member 50. A storage space 5 is formed inside the enclosure of the front member 20, rear member 30, right side member 40, and left side member 50, and a nozzle 6 extending into the storage space 5 is attached to the rear member 30 via a support member 8. A plastic bag (not shown) or the like is placed in the storage space 5. The assembled modular toilet 1 is an octagonal prism. The main body 2 is an octahedron, and the upper end 3 and lower end 4 are octagons of the same shape. The front-to-back length L of the main body 2 is longer than the left-to-right width W of the main body 2, and the left-to-right width W of the front of the main body 2 F The width W is the left-right width of the rear of the main unit. R Shorter than [the specified length]. Each component 10, 20, 30, 40, and 50 is made of metal such as stainless steel or aluminum, or resin such as polyethylene or polyamide.

[0023] Here, the toilet seat member 10, front member 20, rear member 30, right side member 40, and left side member 50 will be described based on the drawings. Figure 3 shows the top surface of the toilet seat member 10, and Figure 4 shows a cross-section of the toilet seat member 10. Figure 5 shows the top surface of the front member 20, and Figure 6 shows the front surface of the front member 20. Figure 7 shows the top surface of the rear member 30, Figure 8 shows the first rear surface of the rear member 30, and Figure 9 shows the second rear surface of the rear member 30. Figure 10 shows the top surface of the left side member 50, Figure 11 shows the first side surface of the left side member 50, and Figure 12 shows the second side surface of the left side member 50. Note that the right side member 40 is symmetrical to the left side member 50 and is therefore omitted from the drawing.

[0024] As shown in Figures 3 and 4, the toilet seat member 10 is made of a flat, thin plate with its front, rear, left, and right ends bent downwards. The toilet seat member 10 has a seat surface portion 11 that is roughly octagonal in the front-to-back direction, a front end portion 12 that extends downwards from the front end of the seat surface portion 11 at a right angle to the seat surface portion 11, a rear end portion 13 that extends downwards from the rear end of the seat surface portion 11 at a right angle to the seat surface portion 11, a right end portion 14 that extends downwards from the right end of the seat surface portion 11 at a right angle to the seat surface portion 11, and a left end portion 15 that extends downwards from the left end of the seat surface portion 11 at a right angle to the seat surface portion 11. An elliptical or elongated opening 16 is formed in the center of the seat surface portion 11. Similar to the main body 2, the front-to-back length L of the seat portion 11 is longer than the left-to-right width W of the seat portion 11, and the left-to-right width W of the front of the seat portion 11 F The width W is the left-right width at the rear of the seat portion 11. R It is shorter than that.

[0025] As shown in Figures 5 and 6, the front member 20 is a flat, thin plate with its top, bottom, left, and right edges bent forward. The front member 20 has a rectangular front portion 21, an upper front end piece 22 that extends forward from the upper end of the front portion 21 at a right angle to the front portion 21, a lower front end piece 23 that extends forward from the lower end of the front portion 21 at a right angle to the front portion 21, a right front end piece 24 that extends forward from the right end of the front portion 21 at an obtuse angle to the front portion 21, and a left front end piece 25 that extends forward from the left end of the front portion 21 at an obtuse angle to the front portion 21. The front portion 21 has a front window portion 26 and a front hole portion 27 for weight reduction. The front window portion 26 is a rectangle that is elongated in the left-right direction and is formed near the upper front end piece 22 and the lower front end piece 23, respectively.

[0026] As shown in Figures 7 to 9, the rear member 30 has three surfaces formed by bending a flat, thin plate at an obtuse angle, with the top, bottom, left, and right ends bent towards the rear. The rear member 30 has a rectangular first rear section 31, a second rear section 32 which is connected at an obtuse angle to the right end of the first rear section 31 and is a rectangle wider than the first rear section 31, a third rear section 33 which is connected at an obtuse angle to the left end of the first rear section 31 and is a rectangle with the same width as the second rear section 32, and from the upper ends of the first rear section 31, the second rear section 32, and the third rear section 33 toward the rear, It has a rear upper end piece 34 that protrudes at a right angle, a rear lower end piece 35 that protrudes from the lower end of each rear section 31, 32, 33 toward the rear at a right angle to each rear section 31, 32, 33, a rear right end piece 36 that protrudes from the right end of the second rear section 32 toward the rear at an obtuse angle to the second rear section 32, and a rear left end piece 37 that protrudes from the left end of the third rear section 33 toward the rear at an obtuse angle to the third rear section 33.

[0027] The first rear portion 31 has a rear hole 38 for weight reduction. The second rear portion 32 has a rear window 39 and a rear hole 38 for weight reduction. The rear window 39 is a rectangle that is elongated in the left-right direction and is formed near the rear upper end piece 34 and the rear lower end piece 35, respectively. Similarly, the third rear portion 33 also has a rear window 39 and a rear hole 38. Note that the third rear portion 33 is symmetrical to the second rear portion 32 and is therefore not shown.

[0028] As shown in Figures 10 to 12, the left side member 50 has two surfaces formed by bending a flat, thin plate at an obtuse angle, with the top, bottom, left, and right edges bent to the left. The left side member 50 has a rectangular first left side portion 51, a second rectangular left side portion 52 that is obtusely connected to the rear end of the first left side portion 51 and has a shorter front-to-back length than the first left side portion 51, an upper left side end portion 53 that extends to the left from the upper ends of the first left side portion 51 and the second left side portion 52 at a right angle to each left side portion 51 and 52, a lower left side end portion 54 that extends to the left from the lower ends of each left side portion 51 and 52 at a right angle to each left side portion 51 and 52, a front left side end portion 55 that extends to the left from the front end of the first left side portion 51 at an obtuse angle to the first left side portion 51, and a rear left side end portion 56 that extends to the left from the rear end of the second left side portion 52 at an obtuse angle to the second left side portion 52.

[0029] The first left side portion 51 and the second left side portion 52 have left side holes 57 and left side windows 58 formed therein for weight reduction. The left side windows 58 are rectangular in shape, elongated in the left-right direction, and are formed near the left upper end piece 53 and the left lower end piece 54, respectively.

[0030] Next, the assembly procedure for each component will be explained. First, the main body 2 is formed by combining the front member 20, rear member 30, right side member 40, and left side member 50. Then, the toilet seat member 10 is attached to the upper end 3 (or lower end 4) of the main body 2. Note that the assembly procedure for the main body 2 described below is just one example, and the assembly procedure for the main body 2 is arbitrary.

[0031] A support member 8 for supporting the nozzle 6 is pre-fixed to the second rear portion 32 of the rear member 30 (see Figures 1 and 2). The support member 8 is positioned on the outer surface of the second rear portion 32 near the rear window portion 39, closer to the rear upper end piece 34. Therefore, the nozzle 6 attached to the support member 8 passes through the rear window portion 39 from the outside to the inside. Since the support member 8 is rotatable about its axis of rotation in the vertical direction, the orientation of the nozzle 6 can be freely changed.

[0032] In Figures 1 and 2, when the front member 20 and the left side member 50 are connected, the front left end piece 25 of the front member 20 and the left front end piece 55 of the left side member 50 overlap, and the bolts and nuts 9 are fastened to connect the two members 20 and 50. Similarly, when the front member 20 and the right side member 40 are connected, the front right end piece 24 of the front member 20 and the right front end piece 45 of the right side member 40 overlap, and the bolts and nuts 9 are fastened to connect the two members 20 and 40.

[0033] When the rear member 30 and the left side member 50 are connected, the bolts and nuts 9 are fastened with the rear left end piece 37 of the rear member 30 and the left rear end piece 56 of the left side member 50 overlapping, thereby connecting the two members 30 and 50. Similarly, when the rear member 30 and the right side member 40 are connected, the bolts and nuts 9 are fastened with the rear right end piece 36 of the rear member 30 and the right rear end piece 46 of the right side member 40 overlapping, thereby connecting the two members 30 and 40.

[0034] With the front member 20 and the rear member 30 facing each other, and the right side member 40 and the left side member 50 facing each other, the main body 2, which is connected at four points: the front left end piece 25 and the left front end piece 55, the front right end piece 24 and the right front end piece 45, the rear left end piece 37 and the left rear end piece 56, and the rear right end piece 36 and the right rear end piece 46, is formed in an annular shape, and a storage space 5 is formed inside (see Figure 2).

[0035] A plastic bag is placed in the storage space 5, and the bag is attached to the upper end 3 of the main body 2.

[0036] At the upper end 3 of the main body 2, the front upper end piece 22 of the front member 20, the left upper end piece 53 of the left side member 50, the right upper end piece 43 of the right side member 40, and the rear upper end piece 34 of the rear member 30 are aligned on the same plane (see Figure 2). Similarly, at the lower end 4 of the main body, the front lower end piece 23 of the front member 20, the left lower end piece 54 of the left side member 50, the right lower end piece of the right side member 40, and the rear lower end piece 35 of the rear member 30 are aligned on the same plane. Therefore, the toilet seat member 10 is attached to the upper end 3 (or lower end 4). The front upper end piece 22, the left side upper end piece 53, the right side upper end piece 43, and the rear upper end piece 34 are housed inside the front end piece 12, the right end piece 14, the left end piece 15, and the rear end piece 13 of the seat surface of the toilet seat member 10. The bag is sandwiched between the upper end 3 and the toilet seat member 10.

[0037] The nozzle 6 is positioned in the housing space 5, with the nozzle opening 7 facing upwards (see Figure 2). Therefore, when cleaning water is sprayed from the nozzle opening 7, the cleaning water is sprayed upwards and passes through the opening 16 of the toilet seat member 10. The nozzle 6 is connected to a manual or electric pump and a container holding the cleaning water via a water supply hose (neither of which are shown). The cleaning solution is water or a chemical solution. After use, the bag is replaced.

[0038] The prefabricated toilet 1 is constructed as described above. Next, the effects of the prefabricated toilet 1 will be explained.

[0039] Because the modular toilet bowl 1 is made of metal or resin, it is significantly more robust than cardboard or other plastic materials. Furthermore, it is more water-resistant than cardboard, making it easy to clean. As a result, it is less prone to breakage and deterioration, allowing for long-term use and making it economical.

[0040] At the upper end 3 of the main body 2, the front upper end piece 22, the left upper end piece 53, the right upper end piece 43, and the rear upper end piece 34 are aligned on the same plane (see Figure 2). Similarly, at the lower end 4 of the main body 2, the front lower end piece 23, the left lower end piece 54, the right lower end piece, and the rear lower end piece 35 are aligned on the same plane, thus having the same shape. Therefore, the toilet seat member 10 can be attached to either the upper end 3 or the lower end 4 of the main body 2. Thus, it can be easily assembled.

[0041] The prefabricated toilet bowl 1 is an octagonal prism, with its front-to-back length L being longer than its left-to-right width W, and the front left-to-right width W F However, the width of the rear W R It is shorter than (see Figure 2). Therefore, it has a shape similar to a typical toilet. Thus, it is easy to use.

[0042] When the pump is activated, the cleaning fluid sprayed from the nozzle 6 and the spray opening 7 passes through the opening 16 of the toilet seat member 10 and hits the user's private parts. Therefore, the user's private parts can be cleaned. At that time, the support member 8 rotates, changing the orientation of the nozzle 6, so the position of the nozzle 6 can be changed forward, backward, left, and right according to the position of the private parts (see Figures 1 and 2).

[0043] Since the toilet seat member 10, front member 20, rear member 30, right side member 40, and left side member 50 are made of flat, thin plates, it is possible to stack the seat portion 11 of the toilet seat member 10, the front portion 21 of the front member 20, the first rear portion 31, second rear portion 32, and third rear portion 33 of the rear member 30, the first right side portion 41 and second right side portion 42 of the right side member 40 (see Figure 2), and the first left side portion 51 and second left side portion 52 of the left side member 50 facing each other. By stacking the members, it becomes easy to store them in a container (not shown), and easy to carry and transport. The order in which the members are stacked is arbitrary.

[0044] Another embodiment of the present invention has a lower end that has a different shape from the upper end. In another embodiment, the support member rotates on a left-right axis, causing the nozzle to swing up and down. Another embodiment does not have a nozzle. In another embodiment, the rear member, right side member, and left side member are streamlined with smoothly curved shapes. In another embodiment, the main body member is a polygonal prism, and the toilet seat member has a shape corresponding to the main body member. In another embodiment, the width from left to right and the length from front to back are the same. In other embodiments, the type of bolt and nut is arbitrary. In the illustrated embodiment, a wing nut is used, but in other embodiments, a regular hexagonal nut is welded on.

[0045] Although embodiments of the present invention have been described in detail above, the present invention is not limited to the embodiments described above. Furthermore, various design modifications can be made to the present invention as long as they do not deviate from the matters described in the claims for utility model registration.
