Description

The present invention relates to a toilet bowl, and more particularly to a toilet bowl that can be made smaller when not in use.

So far, various toilet bowls have been proposed (see, for example, Patent Document 1).
Patent Document 1 provides "a portable toilet bowl (51) as shown in FIG. 15". The toilet body (52) of the portable toilet (51) has an outer container (53) and a toilet container suspended in the outer container (53) from the upper surface opening (54) of the outer container (53). 55), a toilet seat (56) is installed on the peripheral edge of the upper surface opening (54) of the outer container (53), and the upper lid (57) is attached to the upper surface opening (54) and the toilet seat (56). Is covered. (Patent Document 1, Paragraph No. 0002) Regarding the conventional toilet bowl, "The front surface of the toilet bowl body (52) has a dome-shaped curved surface to reduce the degree of openness of the user. In order to reduce the degree, the user must sit on the front side of the toilet bowl body (52), the posture becomes unstable, and small water flows from the front end of the toilet bowl (55) to the inside of the outer container (53). There is also a risk of spilling. (Paragraph No. 0003 of Patent Document 1), "Providing a portable toilet bowl that allows a person to sit deeply and use a comfortable posture without increasing the degree of open legs" (Patent Document 1). The toilet bowl made for (summary task) is disclosed. Specifically, the toilet bowl disclosed in Patent Document 1 is "a portable toilet bowl characterized by forming leg storage recesses on both front sides of the toilet bowl body" (claim 1 of Patent Document 1). "If the user sits on the toilet bowl body (2) and stores both legs in the leg storage recesses (6,6), he / she can sit deeply on the toilet bowl body (2) without increasing the leg opening degree. Can be done. (The beginning of paragraph number 0005 of Patent Document 1).

The portable toilet bowl disclosed in Patent Document 1 states, "If both legs are stored in the leg storage recesses on both front sides of the toilet bowl body, it is possible to sit deeply on the toilet bowl and take a comfortable posture, especially for girls, without increasing the degree of openness. (Paragraph No. 0021 of Patent Document 1), but the size of the toilet can be large and inconvenient for transportation and storage. rice field.

Japanese Unexamined Patent Publication No. 2000-041893 (for example, abstract, claim 1, detailed description of the invention 0001 to 0005, 0021, FIGS. 1, 3, 15, etc.)

Therefore, it is an object of the present invention to provide a toilet bowl that can be made smaller when not in use (for example, when transporting or storing) than when in use (when receiving defecation).

The toilet bowl of the present invention (hereinafter referred to as "the toilet bowl") is vertically rotatable and attached to the inner surface of the cylinder portion that surrounds the defecation space that receives defecation from above from the side and the cylinder portion that faces the defecation space. A toilet bowl provided with a bottom plate that defines the bottom surface of the defecation space, and the rotation position of the bottom plate with respect to the cylinder portion defines the bottom surface of the defecation space in the usage state where the cylinder portion surrounds the defecation space. The downward rotation of the bottom plate is restricted by the moving position, and the size of the internal space of the cylinder part perpendicular to the rotation axis of the bottom plate with respect to the cylinder part in the top view is narrower than in the used state. It is a toilet bowl that you get.

This toilet bowl is provided with a cylinder and a bottom plate.
The cylinder part surrounds the defecation space from the side, and the defecation space accepts defecation from above (meaning the upper part when the toilet bowl is installed on a horizontal surface).
The bottom plate is rotatably attached to the inner surface of the cylinder (the surface of the cylinder facing the defecation space) in the vertical direction (the direction that has a vertical component when the toilet is installed on a horizontal surface), and the bottom surface of the defecation space. (Usually, the upper surface of the bottom plate defines the bottom surface of the defecation space).
Then, the tubular portion can be in a used state and a narrow state. The state of use is a state in which the defecation space receives defecation from above, and a tubular portion surrounds the defecation space. The narrow state is the dimension in the top view of the internal space of the cylinder along the direction perpendicular to the rotation axis with respect to the cylinder of the bottom plate (for example, when the toilet is installed on a horizontal plane, the toilet is viewed from vertically above. (Top view), the dimension of the internal space along the direction perpendicular to the rotation axis) is smaller than that in the used state.
Further, in the used state, the rotation position of the bottom plate with respect to the cylinder portion is restricted (for example, prohibited or restricted) from the downward rotation of the bottom plate at the used rotation position defining the bottom surface of the defecation space. It should be noted that restricting the downward rotation of the bottom plate at the used rotation position is not limited to the use of various methods, but for example, the bottom plate abuts on the inner surface of the cylinder (for example). , The edge of the bottom plate that moves up and down due to the rotation of the bottom plate abuts on the inner surface of the cylinder), the lower surface of the bottom plate abuts on the protrusions formed so as to protrude from the cylinder into the defecation space, and the inner surface of the cylinder. The tubular portion engaging means (for example, a hook or a button) formed on the bottom plate and the bottom plate engaging means (for example, a hook or a button) formed on the bottom plate are engaged with each other. , The use of a connecting means (exemplifying wire rods, rods, etc.) for detachably connecting the bottom plate and the cylinder portion can be mentioned.
According to this toilet device, the cylinder of the bottom plate is used in a state where the cylinder surrounds the defecation space (in the top view, the dimension of the internal space of the cylinder perpendicular to the rotation axis of the bottom plate with respect to the cylinder is relatively large). The rotation position with respect to the part is the use rotation position where the bottom plate defines the bottom surface of the defecation space. The rotation position of the bottom plate with respect to the cylinder portion (for example, the rotation position where the bottom plate does not interfere with the cylinder portion when the cylinder portion is changed from the used state to the narrow state) is set so that the bottom plate can be rotated with respect to the cylinder portion. By making the internal space dimension of the cylinder part smaller than the used state in the top view along the direction perpendicular to the rotation axis and making the cylinder part narrower, the cylinder in the used state at the time of use (when accepting defecation) This toilet can be made smaller by using a tubular portion that is narrower than the portion when not in use (for example, when transporting or storing).

In this toilet, the tubular portion may be formed by rotatably attaching a plurality of side plates whose inner surface defines a defecation space to each other (hereinafter referred to as "rotating side plate main toilet").
By doing so, these plurality of side plates are rotatably attached to each other, and the plurality of side plates can rotate between the used state and the narrow state. The number of side plates may be 2 or more (for example, the side plates of 2 form the "V" shape of the alphabet in the top view), but if it is 3 or more, a flat side plate is used. It is also possible to surround the defecation space (in the case of 3, the side plates of any of the adjacent flat plates of 3 can be detached from each other so that the side plates can be rotated in the removed state. If it is 4 or more, the side plates can be rotated and used without being detachable between any of the pair of side plates adjacent to each other (while keeping all the plurality of side plates connected). And can transition between narrow states.

Rotating side plate In this toilet, a plurality of side plates are 4 or more side plates, and the rotation angle between the plurality of side plates changes while all the plurality of side plates are connected, so that the usage state and width are changed. It may be a toilet that transitions between a narrow state (hereinafter referred to as "4 or more side plate main toilet bowl").
As described above, if the plurality of side plates are four or more side plates, the plurality of side plates are connected to each other without removing any of the pair of side plates adjacent to each other. The rotation angle can be changed to make a transition between the used state and the narrow state, and the transition is compared with the case where it is necessary to attach / detach between the side plates in the transition between the used state and the narrow state. Easy and quick.

4 or more side plates In this toilet, the cylinder portion abbreviates a square cylinder, and the plurality of said ones rotatably connected around four rotation axes along four sides parallel to each other of the square cylinder. It may be formed by the side plates of 4 which are side plates.
The plurality of side plates are used as the side plates of 4, and the side plates of 4 form a square cylinder which is a square pillar having an internal space in which both bottom surfaces are opened and the both bottom surfaces are communicated with each other. The side plates of the four have four sides parallel to each other of the square cylinder (all of the four sides have one end on one bottom surface of both bottom surfaces and the other end on the other bottom surface of both bottom surfaces. ) Is rotatably connected around the rotation axis of 4 to form a tubular portion that omits the square tube. By doing so, it is possible to change the rotation angle between the side plates in a state where all the plurality of side plates are connected to make a transition between the used state and the narrow state with a small number of side plates. It can be configured to reduce the manufacturing cost of this toilet and make the use of this toilet convenient.

Rotating side plate In this toilet, when the bottom plate is used with respect to the cylinder part, the edge of the bottom plate comes close to or abuts on the inner surface of the cylinder part, so that the rotation angle between the plurality of side plates changes. It may be regulated and the state of use may be maintained.
When using this toilet (when accepting defecation), it is necessary to maintain the usage state in which the cylinder part surrounds the defecation space, and the cylinder part has multiple side plates whose inner surface defines the defecation space rotate with each other. When it is formed by being movably attached, it is possible to maintain the used state by restricting (prohibiting or limiting) the change in the rotation angle between the plurality of side plates forming the tubular portion. The regulation of the change in the rotation angle between the plurality of side plates can be used in various ways and is not limited in any way. For example, the distance between the side plates whose distance changes due to the change in the rotation angle. It can be exemplified that a connecting member is detachably provided so that In particular, the rotation position of the bottom plate with respect to the cylinder portion defines the bottom surface of the defecation space. If the change in the moving angle is regulated (by rotating the bottom plate from the used rotation position, the bottom plate does not come close to or come into contact with the inner surface of the cylinder (inner surface of the side plate), and between a plurality of side plates. Changes in the rotation angle are allowed), and the used state can be maintained without requiring special means for regulating the change in the rotation angle between the side plates.

Rotating side plate In this toilet, the cylinder portion is formed by the side plates of 4 which are the plurality of side plates rotatably connected around the rotating shafts of 4 along the four parallel sides of the square cylinder. The square cylinder is abbreviated, and the bottom plate is rotatably attached to the inner surface of one side plate of the four side plates, and the bottom plate is adjacent to the one side plate of the four side plates at the used rotation position with respect to the cylinder portion. By the edge portion of the bottom plate approaching or abutting on the inner surface of the pair of side plates, the change in the rotation angle between the side plates of the four may be restricted and the used state may be maintained.
The plurality of side plates are used as the side plates of 4, and the side plates of 4 form a square cylinder which is a square pillar having an internal space in which both bottom surfaces are opened and the both bottom surfaces are communicated with each other. The side plates of the four have four sides parallel to each other of the square cylinder (all of the four sides have one end on one bottom surface of both bottom surfaces and the other end on the other bottom surface of both bottom surfaces. ) Is rotatably connected around the rotation axis of 4 to form a tubular portion that omits the square tube. Then, the bottom plate is rotatably attached to the inner surface of one of the four side plates. When the bottom plate is in use rotation position, the side plates of the four are close to each other or abut on the inner surface of a pair of side plates adjacent to the one side plate (the bottom plate is rotatably attached) among the four side plates. Since the change in the rotation angle between the side plates is regulated and the used state is maintained, the rotation angle between the side plates is changed while all the side plates are connected by a small number of side plates of 4 to change the used state. It is possible to make a transition between the narrow state and the bottom plate by approaching or abutting the inner surface of the pair of side plates on both sides of the bottom plate at the use rotation position (rotating the bottom plate from the use rotation position). Therefore, the bottom plates do not come close to or come into contact with the inner surfaces of the pair of side plates, and the change in the rotation angle between the side plates of 4 is allowed), and the change in the rotation angle between the side plates is regulated. It is possible to reliably maintain the state of use without the need for special means, reduce the manufacturing cost of this toilet bowl, and make the use of this toilet bowl convenient.

In this toilet, a protruding portion protruding into the defecation space is provided on the inner surface of the cylinder portion, and the bottom plate at the used rotation position is placed on the protruding portion so that the bottom plate rotates at the used rotation position. It may be regulated.
In this way, a protrusion protruding into the defecation space is provided on the inner surface of the cylinder, and the bottom plate at the use rotation position is placed on the protrusion, so that the bottom plate is restricted from rotating downward at the use rotation position. By doing so, the downward rotation of the bottom plate can be reliably regulated at the use rotation position by a simple configuration in which the protrusion is provided on the inner surface of the cylinder portion.

In this toilet, when the toilet is placed on a horizontal flat surface, the upper surface of the bottom plate at the position of rotation in use is slanted with respect to the horizontal plane (hereinafter referred to as "bottom plate inclined toilet"). ) May be.
By doing so, when the defecation space accepts defecation from above, the upper surface of the bottom plate that defines the bottom surface of the defecation space is slanted with respect to the horizontal plane, so that the defecation received in the defecation space is slanted. It can move along the upper surface of the bottom plate and gather downward, and can prevent the stool that has fallen on the lower part of the upper surface of the bottom plate from being scattered from there, and post-treatment such as taking out the stool can be performed. Make it easy.
The fact that the upper surface of the bottom plate is slanted with respect to the horizontal plane means that when the toilet is placed on a mounting surface that is a horizontal plane, it is a vertical vertical surface that intersects the upper surface so as to cross the upper surface. It is also horizontal at the end face of the upper surface due to all the transverse vertical planes parallel to the first vertical plane between a first vertical plane and a second vertical plane parallel to the first vertical plane and a transverse vertical plane. The height of the upper surface simply decreases as it goes in either of the same directions (eg, the upper surface is downward-sloping or downward-sloping at the end faces of the upper surface due to all the transverse vertical planes). Further, if the entire upper surface is slanted with respect to the horizontal plane, the above-mentioned effect of collecting stools is more successfully achieved. The inclination of the upper surface is the maximum value obtained by dividing the vertical height difference of the upper surface appearing on the end surface of the upper surface by the horizontal distance (when considering various first vertical faces and second vertical faces). If it is too small, the above-mentioned effect of collecting stools will not be fully exerted, and if it is too large, problems such as difficulty in taking out stools may occur. It is more preferably 25 degrees or more, most preferably 30 degrees or more, preferably 55 degrees or less, more preferably 45 degrees or less, and most preferably 40 degrees or less (about 35 degrees). Best).

In the bottom plate inclined toilet bowl, the upper surface of the bottom plate may be lowered as it approaches the position of the inner surface of the cylinder portion to which the bottom plate is rotatably attached.
By doing so, the upper surface of the bottom plate descends (the height of the upper surface simply decreases) as it approaches the position of the inner surface of the cylinder to which the bottom plate is rotatably attached. Since it is held between the upper surface of the cylinder and the inner surface of the cylinder portion to which the bottom plate is rotatably attached, post-processing such as defecation can be facilitated.

In this toilet bowl, the bottom plate has a bottom plate main body including a flat plate member whose main surfaces are substantially flat surfaces, and a grip portion formed on one main surface of the bottom plate main body (hereinafter, "grasping"). It may be called "partial toilet bowl").
In this way, the bottom plate has a bottom plate main body and a grip portion formed on one main surface of the bottom plate main body, so that the bottom plate that can be rotatably attached to the inner surface of the tubular portion in the vertical direction is vertically oriented. Since the grip portion can be gripped and rotated when rotating to, the bottom plate can be smoothly and reliably rotated when transitioning between the used state and the narrow state.
The grip portion is not limited as long as it can be easily and surely gripped, but for example, a handle, a handle, or a protrusion formed so as to protrude from one main surface of the bottom plate main body, or Examples thereof include recesses and openings provided on one surface of the bottom plate main body.

Grip portion In this toilet, the grip portion is formed so as to protrude from one main surface of the bottom plate main body, and the bottom plate is rotated with respect to the cylinder portion and the bottom plate rotates on the one main surface of the bottom plate main body. A recess or an opening accommodating at least a part of the grip portion may be formed on the inner surface of the cylinder portion when it comes into contact with or is brought close to the inner surface of the freely attached cylinder portion.
If the grip portion is formed so as to protrude from one main surface of the bottom plate body, the bottom plate is rotated with respect to the cylinder portion to form the one main surface (the surface on which the grip portion is formed) of the bottom plate body. May interfere with the inner surface of the cylinder when the grip is in contact with or close to the inner surface of the rotatably attached cylinder. In such a case, by forming a recess or an opening accommodating at least a part of the grip portion on the inner surface of the cylinder portion, interference of the grip portion with the inner surface of the cylinder portion is prevented or reduced, and the transition to the narrow state is achieved. Smooth.

In this toilet, the edge portion of the bottom plate may come into contact with the inner surface of the tubular portion to restrict downward rotation at the use rotation position.
By doing so, the bottom plate edge that moves up and down due to the rotation of the bottom plate comes into contact with the inner surface of the cylinder. Therefore, the downward rotation of the bottom plate can be reliably regulated at the used rotation position without providing any special means.

The embodiments of the present invention will be described in detail with reference to the drawings, but the present invention is not limited thereto.

FIG. 1 is a diagram showing a portable toilet bowl (main toilet bowl) 11 according to an embodiment of the present invention, and in detail, FIG. 1A is a plan view (top view) of the toilet bowl 11 and is shown in FIG. 1 (top view). b) is a left side view of the toilet bowl 11 (shown from the direction of arrow A in FIG. 1 (a)). FIG. 2 is a cross-sectional view taken along the line BB of FIG. 1 (a). The toilet bowl 11 will be described with reference to FIGS. 1 and 2.
Hereinafter, for ease of explanation and understanding, X-axis, Y-axis and Z-axis orthogonal to each other are used, and these are indicated by arrows X, Y and Z in the figure.

Roughly speaking, the toilet bowl 11 includes a side plate portion 20 and a bottom plate portion 30 rotatably attached to the inner surface of the side plate portion 20.
The "left", "right", "top" and "bottom" used in the explanation are the users who use the toilet bowl 11 straddling the toilet bowl 11 (not shown, the upper surface of the right side plate 25 described later). The right leg is above 25a and the left leg is above the top surface 27a of the left plate 27.) Refers to "left", "right", "up" and "bottom" (Y-axis in the left-right direction). The front-back direction is along the X-axis, and the up-down direction is along the Z-axis.)

The side plate portion 20 has a front side plate 21, a rear side plate 23, a right side plate 25, and a left side plate 27, and the main surface of each of the front side plate 21, the rear side plate 23, the right side plate 25, and the left side plate 27 is rectangular. It is composed of a rectangular plate member.
In the state shown in FIGS. 1 and 2 (hereinafter referred to as “installed state”), the lower portion 21d of the front side plate 21 (see particularly FIG. 2), the rear side plate 23, the right side plate 25, and the left side plate 27 form four sides. A cylinder (a hollow square pillar with no bottom and no lid) is formed along the four sides of a rectangular parallelepiped parallel to the Z axis. Further, in the installed state, both main surfaces of the front side plate 21 (two sides of the four sides of the rectangle formed by the main surface are parallel to the Z axis) and both main surfaces of the rear side plate 23 (the main surface is formed). Two of the four sides of the rectangle are parallel to the Z axis) is approximately perpendicular to the X axis, and both main surfaces of the right plate 25 (two of the four sides of the rectangle formed by the main surface are the Z axis). (Parallel to the Z axis) and both main surfaces of the left side plate 27 (two of the four sides of the rectangle formed by the main surface are parallel to the Z axis) are substantially perpendicular to the Y axis.

The right side plate 25 is attached to the front side plate 21 by a first hinge 29c1 so as to be rotatable around the first rotation shaft c1. The left side plate 27 is attached to the front side plate 21 by a second hinge 29c2 so as to be rotatable around the second rotation shaft c2. The right side plate 25 is attached to the rear side plate 23 by a third hinge 29c3 so as to be rotatable around the third rotation shaft c3. The left side plate 27 is attached to the rear side plate 23 by a fourth hinge 29c4 so as to be rotatable around the fourth rotation shaft c4. The first rotation shaft c1, the second rotation shaft c2, the third rotation shaft c3, and the fourth rotation shaft c4 are all parallel to the Z axis, and the first rotation shaft c1 and the second rotation The distance between the shaft c2 is equal to the distance between the third rotation shaft c3 and the fourth rotation shaft c4, and the distance between the first rotation shaft c1 and the third rotation shaft c3 is the first. It is equal to the distance between the 2 rotation shaft c2 and the 4th rotation shaft c4 (in the installed state, the 1st rotation shaft c1, the 2nd rotation shaft c2, the 3rd rotation shaft c3 and the 4th rotation). Each of the axes c4 is along the four sides of the virtual square.)
The lower surface 21b of the front side plate 21, the lower surface 23b of the rear side plate 23, the lower surface 25b of the right side plate 25, and the lower surface 27b of the left side plate 27 substantially face a plane perpendicular to the Z axis. The upper surface 23a of the rear side plate 23, the upper surface 25a of the right side plate 25, and the upper surface 27a of the left side plate 27 substantially face another plane perpendicular to the Z axis.

The bottom plate portion 30 includes a bottom plate main body 31 made of a flat plate member having a rectangular main surface, and a handle 33 attached to the upper surface 31a of the bottom plate main body 31.
One side of the bottom plate main body 31 is rotatably attached to the inner surface of the side plate portion 20 (specifically, the front side plate 21 (lower portion 21d)) by the fifth hinge 29d so as to be rotatable around the rotation shaft c5 parallel to the Y axis. ing. In the installed state, the lower surface 31b (particularly see FIG. 2) of the bottom plate main body 31 abuts from above on the bottom plate stopper 24, which is a protrusion provided on the inner surface of the side plate portion 20 (specifically, the rear side plate 23) (see FIG. 2). In FIG. 2, the bottom plate main body 31 is supported by further clockwise rotation of the bottom plate main body 31 around the rotation shaft c5).

In the bottom plate main body 31 supported by the fifth hinge 29d and the bottom plate stopper 24 in this way, as shown in FIG. 1A, the outer edge of the bottom plate main body 31 is on the inner surface of the rear side plate 23, the right side plate 25, and the left side plate 27. Since they are close to each other, as shown in FIG. 1A, the side plate portion 20 maintains a state in which a rectangle is substantially formed in a plan view (top view). That is, the angle formed by the adjacent plates of the front side plate 21, the rear side plate 23, the right side plate 25, and the left side plate 27 constituting the side plate portion 20 (all about 90 degrees in the state of FIG. 1A) is about 90 degrees. When trying to change from, the outer edge of the bottom plate main body 31 comes into contact with the inner surfaces of the rear side plate 23, the right side plate 25, and the left side plate 27, and the change is prohibited.
The handle 33 is composed of a ridge-shaped member attached to the upper surface 31a of the bottom plate main body 31, and by grasping and pulling up the handle 33 by hand, the bottom plate main body 31 is counterclockwise around the rotation shaft c5 in FIG. It can be rotated around and pulled up. Further, the front side plate 21 (here, the upper portion 21c) is formed with a handle accommodating portion 21h, which is an opening for inserting and accommodating the handle 33, as will be described later.

FIG. 3 shows that in the toilet bowl 11 in the state shown in FIGS. 1 and 2, the handle 33 is grasped by hand (not shown) and pulled up (in FIG. 2, the bottom plate main body 31 is counterclockwise around the rotation shaft c5. 3 (a) shows a view seen from the same direction as FIG. 1 (a), and FIG. 3 (b) shows a view showing a state (rotated to). 3 (a) is a sectional view taken along the line BB (that is, the same sectional position as the sectional view shown in FIG. 2).
From the state shown in FIGS. 1 and 2, the bottom plate main body 31 rotates counterclockwise in FIG. 2 around the rotation shaft c5, and in the state of FIG. 3, the bottom plate main body 31 is substantially upright (bottom plate main body). Both main surfaces 31a and 31b of 31 are substantially perpendicular to the X-axis), and the handle 33 is penetrated and accommodated in the handle accommodating portion 21h. By rotating the bottom plate main body 31 clockwise around the rotation shaft c5 in FIG. 3B, the handle 33 can be removed from the handle accommodating portion 21h and returned to the state shown in FIGS. 1 and 2.

In the state shown in FIG. 3, since the outer edge of the bottom plate main body 31 is not close to the inner surfaces of the rear side plate 23, the right side plate 25, and the left side plate 27, the side plate portion 20 substantially forms a rectangle in a plan view (FIG. 3A). The state of being is not maintained. Therefore, the first hinge 29c1, the second hinge 29c2, the third hinge 29c3, and the fourth hinge 29c4 have the first rotation shaft c1, the second rotation shaft c2, the third rotation shaft c3, and the fourth rotation shaft c4, respectively. The side plate portion 20 can be folded freely from the state of FIG. 3A to the state of FIG. 4 as in the state of FIG. Specifically, when transitioning from the state of FIG. 3A to the state of FIG. 4, both the angle formed by the front side plate 21 and the right side plate 25 and the angle formed by the rear side plate 23 and the left side plate 27 are both. As the number increases, both the angle formed by the front side plate 21 and the left side plate 27 and the angle formed by the rear side plate 23 and the right side plate 25 decrease, and the side plate portion 20 is a parallelogram in a plan view (FIG. 4). Is roughly formed. On the contrary, from the state of FIG. 3A, both the angle formed by the front side plate 21 and the right side plate 25 and the angle formed by the rear side plate 23 and the left side plate 27 decrease, and at the same time, Both the angle formed by the front side plate 21 and the left side plate 27 and the angle formed by the rear side plate 23 and the right side plate 25 increase, and the side plate portion 20 can substantially form a parallelogram in a plan view. .. By making the side plate portion 20 substantially form a parallelogram in the plan view (top view) in this way, the side plate portion 20 perpendicular to the rotation axis c5 in the top view (FIGS. 1A and 4) The dimension of the internal space is dimension Q1 in FIG. 1A, whereas it is dimension Q2 (Q2 <Q1) in FIG. 4, so that the toilet bowl 11 can be transported and stored as shown in FIG. Make it easy. Further, the width E (distance between the outer surface of the right side plate 25 and the outer surface of the left side plate 27) of the toilet bowl 11 can be reduced (the width E in FIG. 4 is smaller than the width E in FIG. 3A). From this point as well, it facilitates the transportation and storage of the toilet bowl 11.

How to use the toilet bowl 11 will be briefly described.
As shown in FIG. 3, the side plate portion 20 of the toilet bowl 11 transported and stored in the state shown in FIG. 4 substantially forms a rectangle in a plan view (specifically, the front side plate 21 and the right side plate).
