Description

[Technical field]

[0001] The present invention relates to a non-flush excrement disposal device that receives excrement in front of the body, and is an assembly-type, simple excrement disposal device. It can be used as a simple urinal that can be stockpiled for disasters, prepared at evacuation sites in the event of a disaster, and is easy to store, transport, and install, is hygienic, and minimizes the burden on managers. [Background technology]

[0002] As a simple assembly toilet for urination, there is a simple assembly-type urinal consisting of a screen, a urinal, a hose, and a tank (for example, JP 2015-142635 A). However, such a simple urinal requires the manager or the like to dispose of the waste contained in the tank, which places a heavy burden on the manager and also poses hygiene issues.

[0003] An invention has been proposed for an easy-to-assemble and install urinal in which the urine receiving section and wall section can be assembled from a foldable sheet-like development diagram (JP Patent Publication 2018-202109). After assembling the urinal, the entire urinal is covered with a funnel section, which is connected to a drain hose and discharged into a manhole.

[0004] One invention concerns a disposable urinal for children that can be folded and carried around, and can be packed with absorbent material after use (Patent Publication No. 2007-520238). The above two inventions show assembly methods using development drawings, and share a common toilet bowl shape. Although they are easy to fold, they are not easy to assemble, as they require different materials than those shown in the development drawings to attach the surfaces or sides for assembly. In addition, they are not rational in shape as a container for urinary discharge during use, and there is waste in the materials required for their manufacture.

[0005] The shape of a men's urinal must be such that it can accommodate the spread of urine discharge and contribute to preventing urine from splashing and dripping. For this reason, it is desirable that the front end of the bowl be placed under the crotch area to serve as a drip receiver, and that there be rims on both the left and right sides with a certain height and width. It is also desirable that the height of the drip receiver and rims be adjusted to accommodate individual differences due to height. The pointed shape of the front end of the toilet proposed in JP 2015-142635 mentioned above provides good accessibility and is effective as a drip receiver, but since there are no rims on either side, it cannot accommodate the spread of the drip and cannot prevent splashing. Regarding the urinals in the above-mentioned Patent Publication No. 2018-202109 and Patent Publication No. 2007-520238, although there are rims on both the left and right wings, the left and right edges on the front side facing people prevent access and do not function as drip receivers.

[0006] Next, from the perspective of stability, the angle between two adjacent planes of the three-dimensional shape must be stably maintained for the three-dimensional structure assembled from the folded state or flat development. In this regard, the invention of JP 2015-142635 uses a folding screen to assemble a urinal by creating fold lines in a thin plate such as cardboard on a flat surface, but it has a combination of planes with multiple folds for one connecting side, and the angle between the planes sandwiching the folds must be maintained only by the thin plate members, making it an extremely unstable three-dimensional shape to be assembled. Regarding the invention of JP2007-520238, the three-dimensional shape after assembling the paperboard is stable, but the six connecting edges on the left and right are a major obstacle to easy assembly. In addition, regarding the invention of JP2018-202109, easy assembly is realized with two connecting edges, but with respect to the two planes adjacent to each other at a predetermined angle by the folding part, the three-dimensional shape assembled from the proposed development diagram has a free end portion on the top of the flap part where no support or tension acts, and is not a stable three-dimensional shape.

[0008] The problem to be solved is to provide an assembled excrement disposal device that is easy to store and transport, can secure a stable three-dimensional shape, and requires the minimum necessary area of ​​thin plate material. We propose an inexpensive and hygienic excrement disposal device that is economical and minimizes the burden on managers. We propose an excrement disposal device that can be used for excrement disposed of in the front of the body, specifically, for men's urinals or for people who have an artificial anus or bladder constructed in the abdomen for excretion. [Means for solving the problem]

[0009] a third valley fold line formed on a thin plate material having an outer shape including a first isosceles trapezoid and a rectangle having an upper base of the first isosceles trapezoid as a lower side and left and right sides whose lengths are equal to or greater than the lengths of the left and right legs of the first isosceles trapezoid, the third valley fold line being formed on the upper base of the thin plate material, the third valley fold line being formed on the right and left legs of a second isosceles trapezoid having an upper base that is a part of the center of the lower base of the first isosceles trapezoid, the third valley fold line being formed on the right and left legs of the second isosceles trapezoid, the third valley fold line being formed on the right and left legs of the first isosceles trapezoid, the third valley fold line being formed on the right and left legs of the first isosceles trapezoid, A back plate of the rectangular portion; A front panel of the second isosceles trapezoidal portion; Side panels of the portions from the left and right legs of the first isosceles trapezoid to the right and left legs of the second isosceles trapezoid; A connecting portion provided on the rear panel and the side panel; A device for receiving excrement comprising: Effect of the Invention

[0010] As a simple non-flush urinal for disaster areas, it is inexpensive, extremely easy to store, and the burden of use is relatively small, as it can be used after covering a plastic bag with a receiving device assembled from thin plate materials such as cardboard or thick paper, and since the whole is covered with a plastic bag, it is hygienic, and waste can be easily disposed of at one's own risk by using a coagulant when used, reducing the burden on the manager. By specializing it for men's urination in disaster areas, it can help to alleviate congestion in unisex toilets. It can also be used as an excretion device for people who have had an artificial anus or bladder constructed in their abdomen or other area for excretion, reducing the burden on people and caregivers who have difficulty using conventional home toilets to dispose of excretion. The shape of the receiver, compared to conventional types, is able to accommodate the spread of excrement in the direction of discharge and helps prevent excrement from scattering and dripping, with the tip of the front of the toilet serving as a drip receiver under the crotch, and rims of a certain height and width on both the left and right wings, and the height of the drip receiver and rims can be adjusted to suit individual differences due to height. While providing these functions, the toilet is structurally stable and uses the minimum amount of flat plate material necessary. These are explained using the following numbers 1 and below.

[0011]

number

[0012] Mathematical formula 1 shows the shape of two solid bodies after assembly, in which the positions of the valley broken line in the first isosceles trapezoid are different, for two developments having the same outer shape consisting of a rectangle and a first isosceles trapezoid with the lower side of the rectangle as the upper base. Mathematical formula 1 (1) shows a development of a thin plate material. The left and right legs of the first isosceles trapezoid are at an angle of θ outward from the perpendicular line connecting the left and right ends of the upper base and the lower base, and the development shows a development having a valley broken line c rotated an angle of α inward from the perpendicular line, and two developments with the perpendicular line a as the valley broken line in one figure. The valley broken line c corresponds to the right and left legs of the second isosceles trapezoid in claim 1. In comparison with the developed views, (2-1) and (3-1) show views in which the first valley fold line is rotated inward around the rotation axis, and at the same time either the valley fold line c or a is folded inward around the rotation axis, and the left and right legs of the first isosceles trapezoid are attached to the sides of the rectangle. (2-1) is an oblique view and (2-2) is a right side view showing the valley fold at the valley fold line c, and (3-1) is an oblique view and (3-2) is a right side view showing the valley fold at the valley fold line a. As shown in the formula 1 (2-1), (α+θ) must be less than 90 degrees in order for the storage section to store excrement. The formula (2-2) expresses the angle β in the side view, β≦α+θ, and Acos is the arc cosine, which is the inverse function of cos. A in the formula (2-2) is the area shown by the thin dotted line at a 45-degree angle to the right in (2-1), and represents the area of ​​the receiving opening of the excrement receiver of the present invention. Also, V is the volume shown by the thin dotted line at a 45-degree angle to the left in (2-1) and (2-2), and represents the capacity of the storage section of the excrement receiver. On the other hand, the pocket section with a as the valley line shown in (3-1) is in the shape of a triangular prism, and in the side view of (3-2), β=θ, and the area At of the entrance of the pocket section and the capacity Vt of the storage section can be calculated by the formula (3-2).

[0013] The formula 1 (3-1) is for comparing a conventional excrement receiving device having a simple and stable structure with the formula 1 (2-1) of the present invention. In the case of a men's urinal, the side between the valley broken lines of c (l' x 2 in Mathematical 1 (1)) in the part of the lower base of the first isosceles trapezoid shown in Mathematical 1 (2-1) is located at the closest position when the user excretes, and by clarifying the center position of the excretory device and shortening the side, it is possible to install it under the crotch, making it easier for the user to approach the device. Also, by making the part other than the valley broken lines of c in the lower base of the first isosceles trapezoid the upper side of the side panel, the side panel spreads out radially from the user and becomes a flat surface at an acute angle to the back panel, and the side panel acts as a rim to prevent the scattering of excrement. Furthermore, a comparison of the area of ​​the receiving opening and the capacity of the storage section of the excretion receiving device calculated using equations (2-2) and (3-2) in mathematical expression 1 as three-dimensional shapes that can be obtained from thin sheet material of the same area shows that the three-dimensional shape shown in (2-1) is a streamlined and efficient shape for a device to store excrement, and also allows for a reduction in the amount of thin sheet material used. Details regarding specific receiving area and capacity are provided below. [Brief description of the drawings]

[0015] In this specification, the term "excrement treatment device" refers to a concept that includes a receiving device for excrement, a bag that covers the receiving device, a coagulant that coagulates excrement, and the like. In the claims, two isosceles trapezoids are described in the development, but an isosceles trapezoid is a shape consisting of an upper base, a lower base that is horizontal to the upper base and has a longer side length than the upper base, and two legs that connect the left and right ends of the lower base to the left and right ends of the upper base, and the interior angles formed by the left and right legs with the lower base are equal. Regarding θ and α in the formula 1, the interior angle formed by the legs of the first isosceles trapezoid with the lower base is (π / 2-θ), and the interior angle of the second isosceles trapezoid is (π / 2-α). The upper base and the lower base do not indicate a positional relationship between up and down. In addition, the second isosceles trapezoid is a concept that includes l'=0 on the development of the formula 1 (1), that is, the length of the upper base is 0. The development diagram described in the claims is a diagram of a solid object cut open and spread out on a single plane, and can also be assembled in reverse to form the solid object. It consists of cut lines that form the outer shape, valley fold lines that are folds for folding the front side inward, and mountain fold lines that are folds for folding the front side outward. The cut lines are represented by solid lines, the valley fold lines by dashed lines, and the mountain fold lines by dashed lines. When assembling using thin plate materials shown in an exploded view as shown in the claims of this application, the connecting parts provided on the back panel and side panels described in the claims, which are essential for assembly, can be of various types, such as a method in which a glue is provided and the panels are attached with an adhesive, or a method using adhesive tape, a stapler, or eyelets for adhesion, but these are omitted in the drawings other than the explanatory diagrams of the connecting parts in Figures 3 to 5 where part of the thin plate materials is used as the connecting part. Thin plate materials are materials that can be assembled in the above-mentioned development diagram, and examples of such materials include paper materials such as cardboard and thick paper, synthetic resin materials, and metal plates. From the perspective of repeated use, however, they must be easily deformable around the fold lines and, after deformation, must easily return to their original shape by either removing or applying force. EXAMPLES

[0016] Fig. 1 shows an embodiment of the present invention, and Fig. 1(1), (2), (3), (4), (5) and (6) show six views, i.e., a plan view, a front view, a bottom view, a left side view, a right side view and a rear view, respectively. Fig. 1(7) is a development view 2. Regarding the development of Figure 1 (7), a trapezoid with the first valley broken line 24 of l as the upper base, the straight line formed by c, d, and e as the lower base, and b and f as the left and right legs is called a first isosceles trapezoid 21. A trapezoid with d as the upper base, l as the lower base, and the second valley broken lines n and m25 as the right and left legs is called a second isosceles trapezoid 23. In addition, a rectangle is formed with the first valley broken line l as the lower side, the cut line h as the upper side, and the cut lines a and g as the left and right sides.

[0017] The relationship between the development 2 and the solid shown in the six-sided drawing will be explained. The first valley fold line 24 in the development is rotated more than 90 degrees around the axis of rotation to make a valley fold, and at the same time, the left and right legs n and m of the second isosceles trapezoid 23 are valley folded, and the legs b and f of the first isosceles trapezoid are attached to the left and right sides a and g of the rectangle 22, respectively, to assemble the solid shown in the six-sided drawing. The front view of FIG. 1(2) is a view from the direction of the user of the excrement receiving device of the present invention, and d in the development, which is the upper side of the front panel 11, is the side closest to the user. The front panel and the back panel 13 are connected by the left and right side panels 12 that are attached to the left and right sides of the back panel, which is rectangular in the front view. The surface formed by the upper side of the front panel, the upper sides of the left and right side panels shown as c and e in the development, and the back panel 13 becomes the excrement receiving opening, and has a large area when viewed from diagonally above. The left and right side views are as shown in Figures 1 (4) and (5), and it can be seen that the inclination of the front and rear panels forms an excrement storage section 15 between the side panels. The shape of the waste receiver is shown in more detail by the numeral 2.

[0018]

number

[0019] The angle θ shown in the development of the formula 2 is the angle between the perpendicular line from the upper base to the lower base of the first isosceles trapezoid and the leg, and α is the angle between the leg of the second isosceles trapezoid and the perpendicular line from the upper base to the lower base of the second isosceles trapezoid. a is an auxiliary line showing the perpendicular line from the upper base of the first isosceles trapezoid, b shows the leg of the first isosceles trapezoid, and c shows the leg of the second isosceles trapezoid. When expressed as a formula, a, b, and c show their respective lengths. l shows the length of 1 / 2 the width of the back panel, and (l' x 2) shows the length of the upper side of the front panel, which is usually the side closest to the user. h in the formula 2(1) is the height of the upper side of the front panel as shown in the "side view," and β in the formula 1(2) shows the interior angle between the back panel and the front panel as shown in the "side view." The above-mentioned h can be found from the "auxiliary diagram for determining height" in equation 2, and in equation (1), h=a×cos(θ+α) / cosα, the angle that side c makes with the vertical side b is (θ+α), and can be found by substituting c for a / cosα in the developed diagram. By finding this h from the "side view" in equation 2, β can be found from the vertical side b and the hypotenuse a, as shown in equation (2) in equation 2. A in equation (3) is the area shown in the "side view" and "auxiliary diagram for determining the area of ​​the receiving opening" in equation 2, and is an important element as a receiving device for excrement. It can be found by finding the length of the upper and lower bases of the isosceles trapezoid in the "auxiliary diagram for determining the area of ​​the receiving opening" and the distance between them from the "side view". In addition, V in formula (4) is the volume shown in the "side view" and "plan view" of formula 2, which is an important element as an excrement receiving device, just like the area mentioned above, and is calculated as 1 / 2 the product of the area of ​​the isosceles trapezoid shown in the "plan view" and the height h. Next, V and V, which are the storage capacity of the two solids shown in formula 1, are calculated by formula 3. t A comparison is made regarding:

[0020]

number

[0021] Based on the formula 1 and the formula 2, the formula 3 is a range in which the excrement receiving device of the present invention, the solid shown in the formula 1(2-1) and the solid shown in the formula 1(3-1), can show superiority in terms of the storage capacity of the storage section. As shown in the formula 3, V = (l + l') / 4 × a 2 ×sin(2×β) Vt = l / 2 × a 2 ×sin(2×θ) Furthermore, because the nature of the sine curve causes a decrease when the angle exceeds 90°, when β>θ is taken into consideration, V>Vt cannot be satisfied unless θ<45°. Therefore, with regard to the capacity of the storage section, a θ of less than 45° is a condition for the present invention to demonstrate its superiority.

[0022] For two three-dimensional shapes assembled by developments having the same outline of the cut lines, the receiving port area and storage capacity are shown in equation 1, and the advantages of the three-dimensional shape according to the present invention are shown by specific numerical calculation examples. Tables 1 and 2 are numerical calculation examples when a=0.3m, l=0.3m in equation 1, θ is a maximum of 45 degrees, and α is a maximum of 45 degrees. Table 1 shows the receiving port area, and Table 2 shows the storage capacity.

[0023] [Table 1]

[0024] The calculation example of the receiving area in Table 1 shows the calculation results of the receiving area by combination of θ and α, where α is calculated from 0 degrees to 45 degrees in the horizontal direction, and θ is calculated from 5 degrees to 45 degrees in the vertical direction, in increments of 5 degrees. When α is 0 degrees, A in equation 1 t This shows the three-dimensional shape shown in (3-1) of equation 1. When α is 45 degrees, in this example, a = 0.3 m and l = 0.3 m, l' in equation 1 is 0, and the length of the upper side of the front panel is 0. θ is calculated in increments of 5 degrees from 5 degrees to 45 degrees. The graph in Table 2 shows the results of this calculation. As shown in the graph, each value of θ is expressed by a two-dot chain line, a one-dot chain line, a dashed line, a solid line, and a different line thickness. As θ increases, the upper side of the side panel becomes longer, and the receiving area becomes larger. On the other hand, α has a mountain shape with a peak in the range of approximately 15 degrees to 35 degrees, and when θ is 5 degrees, α peaks at a position of approximately 30 degrees to 35 degrees, and the receiving area is approximately 422 cm 2When θ is 15 degrees, the peak occurs at about α 30 degrees, and the peak is about 790 cm 2 When θ is 25 degrees, α peaks at approximately 25 degrees, and the peak is about 1115 cm 2 When θ is 35 degrees, α peaks at a position between 20 and 25 degrees. That is, the larger θ is, the smaller the maximum value of α becomes for the receiving port area. In this example, when θ is approximately 30 degrees or less, regardless of the value of α, the three-dimensional shape of the present invention shown in (2-1) of equation 1 exceeds the receiving port area of ​​the three-dimensional shape (α=0) shown in (3-1) of equation 1.

[0025] [Table 2]

[0026] Table 2 is a calculation of the storage capacity (volume) under the same conditions as Table 1. In comparison when α is 0 degrees, the larger θ is, the larger the capacity is. The calculated values ​​in Table 2 are shown in a graph. According to this, for the maximum storage volume at the same θ, at θ5 degrees, the peak is about 5.9 liters at a position of approximately α30 degrees, at θ10 degrees, the peak is about 8 liters at a position of approximately α25 degrees, and at θ15 degrees, the peak is about 9.4 liters at a position of approximately α20 degrees. In this way, as θ increases, the maximum value α of the storage volume decreases, which is the same tendency as the receiving port area described above. At θ45 degrees, α is maximum at 0 degrees, so if only the storage capacity is taken into consideration, the three-dimensional shape according to the present invention has no advantage. This shows the results of the study of Equation 3.

[0027] The above study compares the three-dimensional assembled shape of the present application with the conventional one obtained from the same area of ​​material, by providing an easy-to-assemble and stable three-dimensional shape, shortening the length of the upper edge of the front panel and lengthening the upper edge of the side panel, making it easier for users to approach the waste receiver, and preventing waste from scattering. Regarding Tables 1 and 2, when θ is 35 degrees or less, the shape of the number 1 (2-1) according to the present invention has a numerical advantage in both the area of ​​the receiving part and the capacity of the storage part, compared to the assembled shape of the number 1 (3-1) assembled from the development drawing of the same outer shape except for the connecting part, by setting α. It can be said that it is extremely efficient as an assembled receiving tool obtained from a thin plate material of the same area. In addition, for a certain θ, the degree of freedom of the shape by setting α is high, and it is possible to set the optimum shape by taking into account factors such as the length of the front side of the front panel closest to the user, the receiving opening area, or the capacity of the storage part. In this way, the present invention is not simply a specific shape adopted from the conventional shape as an assembled urinal, but a new concept of a second isosceles trapezoid is introduced, and it is possible to obtain the optimum shape as a urinal by setting the internal angle of the legs, and it has an extremely advantageous effect compared to the conventional invention.

[0028] Next, based on the developed view 2 shown in Figure 1 (7), the connecting portion described in claim 3 is a part of the thin plate material, and for an excrement receiving device that can be assembled using only the thin plate material, the connecting portion for forming the three-dimensional shape shown in Figures 1 (1) to (6) is shown. In Fig. 3, a T-shaped connecting portion 51 is provided at the edge of the side panel, and a T-shaped receiving portion 52 is provided at the side of the back panel. The connecting portion described in the claims is a concept that includes the above T-shaped connecting portion and the T-shaped receiving portion, as shown in Fig. 3(6). This is the same for other connecting structures. In comparison with the development view of Fig. 3(6), an enlarged view of the T-shaped receiving portion provided at the side of the back panel is shown in Fig. 3(1), and an enlarged view of the T-shaped connecting portion provided at the edge of the side panel is shown in Fig. 3(2). In comparison with the T-shaped receiving portion of the back panel, which is represented by a cut line for removal, the T-shaped connecting portion is a T-shaped protrusion on the side material. The webs of the T-shaped receiving portion and the T-shaped connecting portion have approximately the same width, and by making the width of the flange of the T-shaped connecting portion larger than the receiving portion, the connecting portion can be inserted into the receiving portion from each other's webs, and can be locked by the flange portion. When inserted, it is in the state shown in Figure 3 (4-1), but as shown by the arrow in the figure, it can be rotated 90 degrees, and when rotated to the same plane, it is in the state shown in Figure 3 (4-2), and an enlarged view from the plane at that time is shown in Figure 3 (3). As shown in Figure 3 (4-1), it can be connected and assembled at a nearly right angle to form the three-dimensional structure shown in Figure 1. An example of use for planar engagement of thin plate materials is shown in the example of Figure 6 described below. EXAMPLES

[0029] Example 2 is an example of a three-dimensional shape assembled by folding the first valley fold line 24 and the second valley fold line 25 around the rotation axis, and attaching the left and right legs of the first isosceles trapezoid 21, which is the edge of the side panel, to the inside of the rectangle, which is the back panel. Figure 2 (7) shows a development 2. In this development, the length of d, which is the upper edge of the front panel, and the position of the second valley fold line associated with it are different from those of Example 1, but the external shape is the same. As shown in Figures 2 (1) to (5), the shape is such that the left and right legs of the first isosceles trapezoid are attached to the inside of the rectangle of the back panel. The closer the attachment position is to the side of the rectangle, the closer the shape is to the shape shown in Example 1. However, Example 2 is inferior to the shape of Example 1 in both the receiving opening area and the storage capacity as discussed above. However, when a part of the thin plate is used as a connecting part and the plate is assembled using only the thin plate, there are advantages in ease of material processing and economy by providing a receiving portion for the connecting part inside the rectangular rear panel, as described below.

[0030] 4 and 5 are explanatory diagrams of a connecting structure different from that of the example of FIG. 3 in the case where the connecting portion is a part of the thin plate material in the first or second embodiment. The development view of Fig. 4(1) shows that the long connecting parts 53, which are protrusions having hooks provided at the edge parts of the side panels, and the back panel are provided with slit parts 54. The long connecting parts are provided at the center parts of the left and right legs of the first isosceles trapezoid described in claim 1, and the slit parts are provided on the side sides of the rectangle described in claim 1. The connecting method is shown in Fig. 4(3)-(5). Fig. 4(3) is an enlarged side view of Fig. 4(1) when connected, and Fig. 4(4) and (5) show the slit parts and the long connecting parts from the side to show the state of inserting the long connecting parts into the slit parts. As shown in the figure, the long connecting parts are provided with hooks, and the length of the slit parts is shorter than the length of the long connecting parts including the hooks. Regarding insertion into the slits, the sides of the side panels rotate around the first and second valley fold lines to attach to the back panel, and by utilizing the flexibility of the side panels, the state shown in Fig. 4(4) can be changed to the inserted state shown in Fig. 4(5), and after the long connecting parts are inserted, a stable assembled shape can be ensured by the hooks of the long connecting parts even against the force of the first and second valley fold lines returning to their original shapes. However, in the connecting structure in the development diagram shown in Fig. 4(1), a slit is provided, so a slit installation allowance 55 shown in the same figure is required. The development view in Fig. 4(6) shows an example of a connecting portion for assembling into a three-dimensional shape in Example 2. The long connecting portion provided at the end of the side panel is the same as that described above, but a slit portion is provided at the attachment position of the end of the side panel inside the rectangular back panel, on a straight line from the intersection of the base and side of the rectangle. The connecting method is the same as above. In the case of Example 2, as shown in the figure, a triangular slit portion installation space 55 is required, but the slit portion can be accommodated inside the rectangular back panel, making it possible to assemble into a three-dimensional shape as shown in the perspective view in Fig. 4(7).

[0031] FIG. 5 shows an example of a connection that takes into consideration the structural stability of the connection shown in FIG. 4. In the development view of FIG. 5(1), a valley fold connection portion 56 is provided at the edge portion of the side panel, a valley fold slit portion 57 is provided at the back panel, and a cutout line for providing a valley fold portion 58 around the slit portion is provided on the rectangular side side of the valley fold slit portion. The connection method is described in FIG. 5(3) to (5). FIG. 5(3) is a schematic diagram from the front direction in which the connection portions in the development view are close to each other. FIG. 5(4) shows a state in which the valley fold slit portion and the valley fold portion around the slit portion are valley folded at about 90 degrees, and the valley fold connection portion of the side panel is valley folded. The connection of the valley fold connection portion to the slit is the same as that shown in FIG. 4(3) to (5), but the insertion direction is different. FIG. 5(4) and FIG. 5(5) after insertion are views from the front direction, and the connection in this example is by insertion from the side direction. The connection in Example 2 by this connection method is shown in Figures 5 (6) and (7). In this example, too, the receiving portion of the connection portion can be accommodated inside the rectangular back panel. Regarding the stability of the structure of a prefabricated three-dimensional object made of thin plate materials that is repeatedly used, the restoring force to the original shape often remains at the folds such as the valley fold line. When assembling from a flat development view as in the present application, the restoring force to the flat or folded state is the subject. In the case of the long connecting part fitting to the slit part in FIG. 4, the hook prevents the long connecting part from being pulled out of the slit part when the restoring force acts in the direction of pulling it out. In the connection shown in FIG. 5, in addition to the hook, in order to ensure a more stable shape, the connecting part is inserted and removed in a direction different from the direction in which the restoring force acts, and prevents the long connecting part from being pulled out of the slit. In the example shown in FIG. 5, in addition to the restoring force, the load of the excrement in the excrement storage part is applied, and the insertion and removal direction of the connecting part is changed to the side by folding the long connecting part and the slit part in the valley, and in the direction of rotating the side panel downward around the first valley fold line, the friction between the side panel end edge other than the long connecting part and the surface of the back panel provides a large resistance to the direction of rotation around the second valley fold line.

[0032] The excrement receiver of claim 1 formed from a development of an outer shape having a first isosceles trapezoid and a rectangle with the upper base of the isosceles trapezoid as its lower side is basically proposed from the viewpoint of eliminating waste of material with as little material as possible and a simple shape, and for example, by cutting the thin plate material of the main body material as shown in Fig. 8, it is possible to manufacture multiple required developments of thin plate materials from a large material without waste. In Fig. 8, multiple developments of thin plate materials 33 have a scrap part 34 left in the middle, but this can be used as a part of the rectangular back panel where the eyelets and string-like bodies are provided above the connecting parts shown in Fig. 6, and the entire material can be used with almost no waste. EXAMPLES

[0033] 6 shows an embodiment in which the excrement receiving device of the present invention is used as a simple assembled toilet for urination. An example of use in which a bag and a coagulant are used in the receiving device is shown. Fig. 6(1) is a front view of the waste receiver after assembly and installation at a height suited to the user. As shown in Example 1, a connecting part 5 is provided in the assembled state of the thin plate material development view, and a separate back panel 13 that can be suspended is connected by providing an eyelet 41 at the top and a string-like body 4 that passes through the eyelet. However, the rectangular back panel in the present invention constitutes a rectangular back panel as a whole, regardless of the presence or position of the connecting part. Fig. 6(2) is a side view. FIG. 6(3) is a front view showing the state in which the bag body 31 is covered over the receiver assembled as shown in FIG. 6(1) and FIG. 6(2). The bag body is transparent and drawn with a thin solid line, and the receiver to be covered is drawn with a thick solid line. As shown in FIG. 6(1), the string-like body 4 is passed through the eyelet 41 from the front to the rear, so that the bag body covering the back panel from the front to the rear can cover the string-like body exposed in front of the back panel. This can also be confirmed from the side view of FIG. 6(4). This is for the sake of hygiene so that the processing tool can be used repeatedly. In this figure, the bag body in the excrement storage space of the receiver is shown with a broken line to show the state in which the bag body covers the storage space and receives the excrement. In this figure, the coagulant 32 is poured in after excretion, but it is also possible to pour in some of the coagulant in advance and use its weight to make it easier to secure the storage space for excrement and to prevent leakage from the seams of the bag body. EXAMPLES

[0034] Figure 7 shows an example of "a thin plate material of a development including an outer shape of a lower end edge that is continuous with a plurality of straight lines or a single or a plurality of curved lines between the intersection points of the left and right legs of a first isosceles trapezoid and the lower base, and the second valley broken line is a valley broken line that reaches the lower end edge" in claim 2. It is interpreted that the three-dimensional shape to be assembled from the development described in claim 1 includes a part of the inside having a concave or convex shape with respect to the outer shape of the development and a curved shape in the outer shape, except for the straightness or flatness of the legs of the first isosceles trapezoid and the face or side of the rectangular part that are connected or joined, but to avoid doubt, claim 2 is prescribed to include a case where a part of the curved line is included in the second isosceles trapezoid. There are cases where an excrement receiver is required to have a shape that is easier to use and more considerate in design than the excrement receivers of Examples 1 and 2. Regarding the upper base of the second isosceles trapezoid being the closest side facing the user, with a view to the act of excreting in front of the user's body, it is necessary to take into consideration, as an exception, cases where a person with an artificial anus or artificial bladder has the convenience of excreting diagonally forward.

[0035] The schematic front view and development view shown in Figure 7 (1-1) and (1-2) are of a receptacle for male urination, and the central bulge of the top base of the second isosceles trapezoid on the side closest to the user enhances its functionality as a urinal, such as reducing leakage, and the upper part of the rectangular joint with the legs 27 of the first isosceles trapezoid on the left and right of the side panel has a tapered recess after assembly, which is suitable for a small plastic bag that covers only the lower part of the toilet bowl. The height of the toilet bowl can be adjusted by the length of the string-like body and the position of the hanging fastener, making it easy to use as a simple toilet bowl for personal use. The schematic diagrams of the front view and the development view shown in Fig. 7 (2-1) and (2-2) are intended for use as an excretion tool for a person who has an artificial anus or an artificial bladder for excretion in the abdomen or the like. When it comes to disposal of excrement from an artificial bladder or an artificial anus, it may be inconvenient to do so in the center of the body. In order to access the toilet bowl biased to the left or right, the linear disposal tool such as in Example 1 and the above-mentioned symmetrical curved disposal tool are designed to be approached by a user on the right side from the front, such as the user shown by the dotted line in Fig. 7 (2-1). For the person who has installed the artificial bladder or an artificial anus, disposal of excrement and washing are performed in different positions, and it is extremely convenient to be able to easily adjust the height by the hanging length of the string as shown in Fig. 6.
