Description

[Technical Field]

[0001] The present invention relates to a portable toilet. [Background technology]

[0002] Portable toilets equipped with a toilet bowl and legs attached to the toilet bowl have been known for some time. In these types of portable toilets, the height of the toilet bowl can be adjusted to suit the user's build. For example, Patent Document 1 discloses a portable toilet equipped with a mechanism for adjusting the length of the legs extending downward from the toilet bowl. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-138898 [Patent Document 2] Japanese Patent Application Laid-Open No. 2015-134040 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, some users of portable toilets find it easier to use by tilting the toilet body more than usual. Even with conventional portable toilets, the toilet body can be tilted by, for example, adjusting the length of the rear legs. However, depending on the shape of the leg surfaces that come into contact with the floor, the toilet body may become unstable when tilted, making it difficult for the user to use comfortably. As described in Patent Document 2, replacing the bottom parts of the legs can stabilize the toilet body even when tilted, but the user must replace the bottom parts every time the toilet body is tilted, which is a cumbersome process.

[0005] The present invention has been made in view of the above points, and its object is to provide a portable toilet that is stable when the toilet body is tilted. [Means for solving the problem]

[0006] The portable toilet of the present invention comprises a toilet body, front legs attached to the toilet body, and rear legs attached to the toilet body, positioned rearward of the front legs, and having an adjustable leg length extending from the toilet body. The toilet body is configured to be tiltable by adjusting the leg length of the rear legs, and the front legs and rear legs have first leg surfaces that come into surface contact with the floor when the toilet body is not tilted, and second leg surfaces that come into surface contact with the floor when the toilet body is tilted.

[0007] In the portable toilet of the present invention, the front and rear legs have first leg surfaces that come into surface contact with the floor when the toilet body is not tilted. Therefore, when a user uses the toilet body when it is not tilted (i.e., under normal circumstances), the first leg surfaces come into surface contact with the floor, thereby stabilizing the toilet body. The front and rear legs also have second leg surfaces that come into surface contact with the floor when the toilet body is tilted. Therefore, when a user uses the toilet body when it is tilted, the second leg surfaces come into surface contact with the floor, thereby stabilizing the toilet body. In this way, whether the toilet body is tilted or not, the toilet body is stably placed on the floor, allowing the user to use it comfortably.

[0008] According to a preferred embodiment of the present invention, the angle between the first leg surface and the floor surface is different from the angle between the second leg surface and the floor surface, and when the difference between the leg length of the rear legs and the leg length of the front legs is a first length, the first leg surface comes into surface contact with the floor surface, and when the difference between the leg length of the rear legs and the leg length of the front legs is a second length that is longer than the first length, the second leg surface comes into surface contact with the floor surface.

[0009] According to the above aspect, the leg surfaces that come into surface contact with the floor surface can be changed depending on the leg length of the rear legs, so the toilet body can be placed stably on the floor surface.

[0010] According to another preferred embodiment of the present invention, the first leg surface is a horizontal surface, and the second leg surface is an inclined surface.

[0011] According to the above aspect, the toilet body can be stably placed on the floor surface.

[0012] According to another preferred aspect of the present invention, the front legs are configured so that the leg length, which is the length the front legs extend from the toilet body, is adjustable.

[0013] According to the above aspect, the height of the toilet body from the floor can be adjusted, allowing the user to use the portable toilet more comfortably.

[0014] According to another preferred embodiment of the present invention, the angle difference between the first leg surface and the second leg surface is 10° or less.

[0015] According to the above aspect, the toilet body does not tilt excessively, allowing the user to use the portable toilet comfortably.

[0016] According to another preferred embodiment of the present invention, the area of ​​the first leg surface is larger than the area of ​​the second leg surface.

[0017] According to the above aspect, the toilet body can be stably supported by the legs during normal use when the toilet is used frequently (i.e., when the toilet body is not tilted).

[0018] According to another preferred aspect of the present invention, the area of ​​the first leg surface of the rear leg is larger than the area of ​​the first leg surface of the front leg.

[0019] According to the above aspect, when a user sits on the toilet body, the load applied to the rear legs is usually large, so by increasing the area of ​​the first leg surface of the rear legs, the toilet body can be more stably supported by the rear legs.

[0020] According to another preferred embodiment of the present invention, the area of ​​the second leg surface of the rear leg is larger than the area of ​​the second leg surface of the front leg.

[0021] According to the above aspect, when the toilet body is tilted, the area of ​​the second leg surface of the rear leg is made larger, thereby making the toilet body more stable. [Effects of the Invention]

[0022] According to the present invention, a portable toilet can be provided that allows for a high degree of freedom in adjusting the height of the toilet bowl body. [Brief explanation of the drawings]

[0024] Hereinafter, an embodiment of a portable toilet according to the present invention will be described with reference to the drawings. It should be noted that the embodiment described here is not intended to limit the present invention in any way. Furthermore, the same reference numerals are used to designate components and parts that perform the same functions, and redundant explanations will be omitted or simplified as appropriate.

[0025] 1, 2, and 3 are perspective views of the portable toilet 10 according to this embodiment. FIG. 1 shows the lid 15 in a closed state. FIG. 2 shows the lid 15 in an open state (the lid 15 is raised). FIG. 3 shows the lid 15 and toilet seat 20 in an open state (the lid 15 and toilet seat 20 are raised). In the following description, the symbols F, Rr, L, R, U, and D in the drawings respectively represent front, rear, left, right, top, and bottom as seen by a user sitting on the toilet body 50. However, these directions are merely defined for the convenience of explanation and do not limit the installation mode of the portable toilet 10 or the present invention in any way.

[0026] As shown in Figures 1, 2, and 3, the portable toilet 10 is a toilet primarily used by caregivers, such as the elderly and physically disabled, and is suitable for use in such situations. The portable toilet 10 is not a toilet that is fixed to the floor, but is a movable toilet. The portable toilet 10 includes a lid 15, a toilet seat 20, a receiving plate 30, a bucket 40, a toilet bowl body 50, a backrest 70, armrests 80, and legs 100.

[0027] The lid 15 is a member that is placed over the toilet seat 20. As shown in FIG. 1, in this embodiment, the lid 15 is a substantially rectangular member that is attached to the rear of the toilet body 50 via a hinge (not shown) provided on the rear edge. The lid 15 is detachably attached to the toilet body 50. The lid 15 rotates around the hinge. A hinge (not shown) is attached to the lid 15 in the middle in the front-to-rear direction. The lid 15 can be folded at the middle in the front-to-rear direction by the hinge. The folded lid 15 can be passed through an opening 71 provided in the backrest 70. By passing the lid 15 through the opening 71 provided in the backrest 70, the position of the lid 15 can be appropriately changed between a position in which it is placed on the toilet seat 20 in front of the backrest 70 (see FIG. 1) and a position in which it is pulled up behind the backrest 70 (see FIG. 2).

[0028] As shown in Figure 2, the toilet seat 20 is positioned in the center of the top of the toilet body 50. The toilet seat 20 is attached to the rear of the backing plate 30 via a hinge (not shown). The toilet seat 20 rotates relative to the backing plate 30 around the hinge. The toilet seat 20 can be appropriately changed between a position where it is positioned on the top of the toilet body 50 (see Figure 2) and a position where it is pulled up from the top of the toilet body 50 (see Figure 3). The toilet seat 20 has a seat surface 21 on which the user rests their buttocks. An opening 22 is formed in the center of the toilet seat 20.

[0029] The backing plate 30 is disposed on top of the toilet body 50. The backing plate 30 is disposed so as to be detachable from the toilet body 50. The toilet seat 20 is disposed on top of the backing plate 30. The backing plate 30 supports the toilet seat 20 so that it can rotate. The backing plate 30 and the toilet seat 20 are integrated. As shown in Figure 3, an opening 31 is formed in the center of the backing plate 30. The backing plate 30 is also referred to as a toilet.

[0030] Bucket 40 is a bucket that receives the user's excrement and may be referred to as a "waste receptacle." Bucket 40 is a container with an open top and a deep bottom. Bucket 40 is placed below toilet seat 20. Bucket 40 is stored in toilet body 50 in a predetermined orientation. Bucket 40 is placed within opening 31 of receiving plate 30. Bucket 40 is removably stored in receiving plate 30. As shown in FIG. 2, a lid 42 (bucket lid) is attached to the opening of bucket 40, and lid 42 is removed when portable toilet 10 is in use. Furthermore, when portable toilet 10 is not in use, it is recommended to keep lid 42 on bucket 40 to prevent odors from escaping.

[0031] FIG. 4 is a perspective view of the toilet body 50. As shown in FIG. 4, the toilet body 50 has a main body section 51, a storage section 52, and a leg support section 55. The main body section 51 is formed in a substantially rectangular parallelepiped shape. A receiving plate 30 (see FIG. 3) is disposed on the upper part of the main body section 51. The storage section 52 is provided in the center of the main body section 51 and is a section that is recessed downward. A bucket 40 is stored in the storage section 52. The leg support sections 55 are provided at the four corners of the main body section 51 (front, rear, left, and right). The leg support sections 55 are formed with through holes 55H that penetrate in the vertical direction. The legs 100 (see FIG. 1) are inserted into the through holes 55H. The leg support sections 55 are sections that support the legs 100. As will be described later, the toilet body 50 is configured to be tiltable by adjusting the leg length of the rear legs 110Rr (see FIG. 1) of the legs 100.

[0032] As shown in FIG. 1 , the backrest 70 includes a left pillar 71L, a right pillar 71R, a backrest 72, and a cushion 73. The left pillar 71L and the right pillar 71R extend upward from both the left and right sides of the toilet body 50. The backrest 72 spans the upper ends of the left pillar 71L and the right pillar 71R. The backrest 72 extends in the left-right direction. The cushion 73 is attached to the front of the backrest 72. The cushion 73 is made of, for example, polypropylene resin or a foamed soft resin material. The area surrounded by the left pillar 71L, the right pillar 71R, and the backrest 72 forms an opening 71 for passing the lid 15 forward and backward.

[0033] As shown in FIG. 1 , the armrest 80 has a left armrest 80L located to the left of the lid 15 and a right armrest 80R located to the right of the lid 15. The left armrest 80L and the right armrest 80R have roughly the same structure. The left armrest 80L and the right armrest 80R have an armrest main body 81 on which the user's elbows rest, and a first support pillar 82 and a second support pillar 83 extending downward from the armrest main body 81. The armrest main body 81 extends in the front-to-rear direction. The second support pillar 83 is located behind the first support pillar 82. The left armrest 80L and the right armrest 80R are attached to the toilet body 50. The left armrest 80L and the right armrest 80R are configured so that their height relative to the toilet body 50 can be adjusted. The left armrest 80L and the right armrest 80R can be removed from the toilet body 50 as needed depending on the needs of the user and / or caregiver.

[0034] As shown in FIG. 1, the legs 100 are provided on the toilet body 50. The legs 100 include a pair of left and right front legs 110F and a pair of left and right rear legs 110Rr located rearward of the front legs 110F. The front legs 110F and the rear legs 110Rr are configured so that the leg length, which is the length the legs extend from the toilet body 50, can be adjusted. The pair of left and right front legs 110F are symmetrical in the left-right direction. That is, the adjustment buttons 218, which will be described later, are located on the inside and face each other. The pair of left and right rear legs 110Rr are symmetrical in the left-right direction. That is, the adjustment buttons 218, which will be described later, are located on the inside and face each other. The rear legs 110Rr are provided with casters 115 for movement. The casters 115 are formed integrally with the leg bottoms 131, which will be described later. The casters 115 are in contact with the floor when the toilet body 50 is in a horizontal state (i.e., the height from a first leg surface 141 of the front leg 110F, described later, to the toilet seat 20 is the same as the height from a first leg surface 141 of the rear leg 110Rr, described later, to the toilet seat 20). The casters 115 are located above the floor when the toilet body 50 is in a horizontal state, and may not be in contact with the floor. The casters 115 may be detachably attached to the rear leg 110Rr. The front leg 110F and the rear leg 110Rr have roughly the same structure except that the front leg 110F is provided with a stepless adjustment mechanism 260, described later, and therefore the front leg 110F will be described below.

[0035] Figure 5 is an exploded perspective view of the right front leg 110F and its surrounding structure. As shown in Figure 5, the leg 100 has a leg body 121, a leg bottom 131, and a restricting member 150. The leg body 121 is an example of a first leg portion. The leg bottom 131 is an example of a second leg portion. In this embodiment, the leg body 121 and the leg bottom 131 of the front leg 110F are formed separately, while the leg body 121 and the leg bottom 131 of the rear leg 110Rr are formed integrally.

[0036] As shown in FIG. 5, the leg body 121 is located above the leg bottom 131. The leg body 121 extends in the vertical direction. The leg body 121 has a hollow leg 122 extending in the vertical direction and a first cylindrical portion 124 located below the leg 122. The leg 122 and the first cylindrical portion 124 are integrally formed. As shown in FIG. 6, the leg body 121 has a restricting wall 128 between the leg 122 and the first cylindrical portion 124. The restricting wall 128 is a wall that restricts the movement of the restricting member 150. The restricting wall 128 has an insertion hole 129 formed therein, into which a portion of a protruding member 135 (described later) of the leg bottom 131 is inserted. The insertion hole 129 penetrates the restricting wall 128 in the vertical direction.

[0037] As shown in FIG. 5, the leg 122 has a substantially rectangular cross section. A plurality of leg-side engaging portions 123 are formed on the outer peripheral surface (here, the left and right surfaces) of the leg 122. The leg-side engaging portions 123 are recessed inward (horizontally) from the outer peripheral surface of the leg 122. The leg-side engaging portions 123 may be through-holes that penetrate the leg 122. The plurality of leg-side engaging portions 123 are spaced apart in the vertical direction. The plurality of leg-side engaging portions 123 are arranged at equal intervals. The leg-side engaging portions 123 are provided at intervals of, for example, 0.3 cm to 3 cm (preferably 0.7 cm to 1.5 cm, e.g., 1 cm). The leg-side engaging portions 123 engage with the main body-side engaging portions 220, which will be described later.

[0038] As shown in FIG. 5, the first cylindrical portion 124 is formed in a cylindrical shape. The outer shape of the first cylindrical portion 124 is larger than the outer shape of the leg portion 122. That is, the outer peripheral surface of the first cylindrical portion 124 is located outward from the outer peripheral surface of the leg portion 122. A first screw groove 125 is formed on the outer peripheral surface of the first cylindrical portion 124. As shown in FIG. 6, a protruding wall 127 extending downward from a restricting wall portion 128 is formed inside the first cylindrical portion 124. The protruding wall 127 is formed outward from an insertion hole 129. Note that the rear leg 110Rr does not have a first cylindrical portion 124 because the leg body portion 121 and the leg bottom portion 131 are integrally formed.

[0039] The leg bottom 131 is in surface contact with the floor surface. As shown in Fig. 5, the leg bottom 131 has a base member 132, a grip member 138 attached to the underside of the base member 132, and a protruding member 135 protruding upward from the base member 132. Note that the rear leg 110Rr does not have the protruding member 135 because the leg body 121 and the leg bottom 131 are integrally formed.

[0040] 5, the base member 132 is formed in a flat shape. The outer shape of the base member 132 is larger than the outer shape of the leg body 121. The base member 132 is made of a different material from the leg body 121.

[0041] As shown in FIG. 6, the grip member 138 is attached to the back surface of the base member 132. The grip member 138 is made of, for example, a rubber material or an elastomer material. Rubber materials and elastomer materials with a durometer type A hardness of 30 to 90 degrees according to JIS K 6253-3 are preferably used. Examples of rubber materials include silicone rubber, natural rubber, nitrile rubber, and butyl rubber. Examples of elastomer materials include olefin-based elastomers and styrene-based elastomers. The grip member 138 firmly secures the portable toilet 10 to the floor when the user uses the portable toilet 10. As shown in FIG. 7, the grip member 138 has a first leg surface 141 and a second leg surface 142. The first leg surface 141 is located rearward of the second leg surface 142. The angle between the first leg surface 141 and the floor surface is different from the angle between the second leg surface 142 and the floor surface. The first leg surface 141 is a surface that comes into surface contact with the floor when the toilet body 50 is not tilted (see FIG. 8). In this embodiment, the first leg surface 141 is a horizontal surface. The second leg surface 142 is a surface that comes into surface contact with the floor when the toilet body 50 is tilted, as will be described later (see FIG. 9). In this embodiment, the second leg surface 142 is an inclined surface. The second leg surface 142 extends upward as it goes forward. The second leg surface 142 is located forward of the leg body portion 121. The angle difference between the first leg surface 136 and the second leg surface 137 is 10° or less (for example, 1° or more and 10° or less; preferably 2° or more and 9° or less; more preferably 3° or more and 7° or less; even more preferably 3° or more and 6° or less; and still more preferably 3° or more and 5° or less; here, 3°).

[0042] As shown in Fig. 8, when the difference between the leg length RrL of the rear leg 110Rr and the leg length FL of the front leg 110F is a first length, the first leg surface 141 comes into surface contact with the floor surface MM. As shown in Fig. 9, when the difference between the leg length RrL of the rear leg 110Rr and the leg length FL of the front leg 110F is a second length that is longer than the first length (for example, the first length plus a few centimeters (for example, 1 cm to 5 cm, for example, 2 cm)), the second leg surface 142 comes into surface contact with the floor surface MM. At this time, the first leg surface 141 does not come into surface contact with the floor surface MM. In this embodiment, the leg length FL of the front leg 110F is the vertical distance from the lower end of a stopper member 240 attached to a clamping member 230 (see FIG. 6), which will be described later, to the first leg surface 141 of the leg bottom portion 131, and the leg length RrL of the rear leg 110Rr is the vertical distance from the lower end of the stopper member 240 attached to the clamping member 230 to the first leg surface 141 of the leg bottom portion 131. In this embodiment, as shown in FIG. 8, when the leg length RrL of the rear leg 110Rr and the leg length FL of the front leg 110F are at their shortest, the leg length FL is longer than the leg length RrL. When the leg length RrL of the rear leg 110Rr and the leg length FL of the front leg 110F are at their shortest, if the leg length FL and the leg length RrL are the same, the first length is zero.

[0043] 10, the first leg surface 141 and the second leg surface 142 of the front leg 110F have different shapes from the first leg surface 141 and the second leg surface 142 of the rear leg 110Rr. The area of ​​the first leg surface 141 of the front leg 110F is larger than the area of ​​the second leg surface 142 of the front leg 110F. The area of ​​the first leg surface 141 of the rear leg 110Rr is larger than the area of ​​the second leg surface 142 of the rear leg 110Rr. The area of ​​the first leg surface 141 of the rear leg 110Rr is larger than the area of ​​the first leg surface 141 of the front leg 110F. The area of ​​the second leg surface 142 of the rear leg 110Rr is larger than the area of ​​the second leg surface 142 of the front leg 110F.

[0044] As shown in FIG. 5, the protruding member 135 is integrally formed with the base member 132. As shown in FIG. 6, the protruding member 135 is inserted into the leg body 121. The protruding member 135 includes a base portion 135A that is inserted into a stepless adjustment mechanism 260 (described later) and rotatably supports the stepless adjustment mechanism 260; a stepped portion 135B that is located above the base portion 135A and prevents the protruding member 135 from being inserted into the leg body 121 by more than a predetermined distance; a tip portion 135C that is located above the stepped portion 135B and engages with a regulating member 150 (described later); and a support portion 135D that is provided inside the base portion 135A and supports the regulating member 150. The protruding member 135 is a tapered protrusion that protrudes outward in stages from the tip portion 135C toward the base portion 135A. The stepped portion 135B is formed so as to be able to contact the protruding wall 127. Step portion 135B comes into contact with protruding wall 127, thereby restricting upward movement of protruding member 135. An insertion hole 135H into which restricting member 150 is inserted is formed in tip end portion 135C. Tip end portion 135C is inserted into insertion hole 129 formed in restricting wall portion 128 of leg body portion 121.

[0045] As shown in FIG. 6, the restricting member 150 is provided between the leg body 121 and the leg bottom 131. The restricting member 150 restricts the distance LS between the leg bottom 131 and the leg body 121 from exceeding a predetermined distance. As shown in FIG. 6, the distance LS is the distance between the lower end of the first tubular portion 124 of the leg body 121 and the upper end of the base member 132 of the leg bottom 131. The restricting member 150 includes a rod-shaped member 151 extending vertically and formed like a rod, a first restricting piece 152 provided at the upper end of the rod-shaped member 151, and a second restricting piece 153 provided at the lower end of the rod-shaped member 151. The rod-shaped member 151 is inserted into an insertion hole 135H formed in the tip 135C of the protruding member 135. The rod-shaped member 151 is supported by a support portion 135D of the protruding member 135. The first restricting piece 152 is engaged with the tip 135C. The first restricting piece 152 is engaged with the tip 135C so as not to rotate more than a predetermined angle. The first restricting piece 152 is located inside the leg body 121. The second restricting piece 153 is engaged with the support portion 135D. The second restricting piece 153 is located inside the leg bottom 131. As shown in FIG. 11, the first restricting piece 152 comes into contact with the restricting wall 128 of the leg body 121 when the distance LS between the leg bottom 131 and the leg body 121 is the largest distance LSL. This prevents the distance LS between the leg body 121 and the leg bottom 131 from widening beyond the largest distance LSL. On the other hand, the first restricting piece 152 does not come into contact with the restricting wall 128 of the leg body 121 when the distance LS between the leg bottom 131 and the leg body 121 is less than the largest distance LSL (see FIG. 6).

[0046] As shown in FIG. 5, the portable toilet 10 is equipped with a leg length adjustment mechanism 200. The leg length adjustment mechanism 200 is configured to adjust the leg length, which is the length by which the leg 100 extends from the toilet body 50. The leg length adjustment mechanism 200 is provided on each of the front leg 110F and the rear leg 110Rr. The leg length adjustment mechanism 200 provided on the front leg 110F is equipped with a stepped adjustment mechanism 210 that adjusts the leg length in steps, and a stepless adjustment mechanism 260 that adjusts the leg length in a stepless manner. On the other hand, the leg length adjustment mechanism 200 provided on the rear leg 110Rr is equipped with a stepped adjustment mechanism 210 that adjusts the leg length in steps. The stepped adjustment mechanism 210 is an example of a length adjustment locking section.

[0047] The stepped adjustment mechanism 210 is configured to be able to perform a fixing operation (see FIG. 6) that fixes the leg 100 to the toilet body 50, and a release operation (see FIG. 12) that makes the leg 100 movable relative to the toilet body 50. The stepped adjustment mechanism 210 is a mechanism that adjusts the leg length of the leg 100 in steps by performing the fixing operation and the release operation. As shown in FIG. 5, the stepped adjustment mechanism 210 includes a ring member 215, a clamping member 230, and a stopper member 240. As shown in FIG. 6, the ring member 215 and the clamping member 230 are fixed to the leg support part 55 of the toilet body 50. In other words, the ring member 215 and the clamping member 230 are part of the toilet body 50.

[0048] As shown in FIG. 5, the ring member 215 has a cylindrical main body portion 216, an adjustment button 218 protruding outward from the outer peripheral surface of the main body portion 216, a main body side engagement portion 220 protruding inward from the inner peripheral surface of the main body portion 216, and an extension portion 222 (see FIG. 6) extending downward from the main body portion 216.

[0049] The adjustment button 218 is configured to move when pressed. As shown in FIG. 12, when the adjustment button 218 is pressed, it moves horizontally (to the right in this case) relative to the clamping member 230 and the leg 100 (leg body 121). When the adjustment button 218 is pressed, the leg 100 can be moved relative to the toilet body 50. That is, as shown in FIG. 12, when the adjustment button 218 is pressed, the engagement between the body-side engagement portion 220 and the leg-side engagement portion 123 of the leg 100 is released, allowing the leg 100 to move up and down relative to the toilet body 50 (release operation). With the adjustment button 218 pressed, the leg length can be adjusted (changed) by changing the leg-side engagement portion 123 that engages with the body-side engagement portion 220. FIG. 13 is a side view showing the longest leg lengths of the leg body 121 of the front leg 110F and the leg body 121 of the rear leg 110Rr. In the example of FIG. 13, adjustment by the stepless adjustment mechanism 260 is not performed. Note that, as will be described later, when the stopper member 240 is attached to the clamping member 230, the adjustment button 218 cannot be pressed (see FIG. 6). As shown in FIG. 6, when the adjustment button 218 is not pressed, the leg 100 can be fixed to the toilet body 50. When the adjustment button 218 is not pressed, the adjustment button 218 is biased in a direction away from the clamping member 230 (i.e., in a direction in which the main body-side engaging portion 220 is inserted into the leg-side engaging portion 123; in this case, to the left) by a coil spring 238 (described later) provided between the back surface of the adjustment button 218 and the clamping member 230. In other words, when the adjustment button 218 is not pressed, the main body-side engaging portion 220 and the leg-side engaging portion 123 engage with each other, and the leg 100 can be fixed to the toilet body 50 (fixing operation).

[0050] As shown in FIG. 6, the body-side engaging portion 220 is provided on the body portion 216 of the ring member 215. That is, the body-side engaging portion 220 is provided on the toilet body 50. The body-side engaging portion 220 protrudes inward (horizontally, to the left in this case) from the inner circumferential surface of the body portion 216. The body-side engaging portion 220 is provided on the opposite side of the adjustment button 218. The body-side engaging portion 220 moves in conjunction with the movement of the adjustment button 218. The body-side engaging portion 220 engages with the leg-side engaging portion 123 of the leg 100. The body-side engaging portion 220 is inserted into the leg-side engaging portion 123. A plurality of body-side engaging portions 220 (for example, four) are provided on the inner circumferential surface of the body portion 216. The plurality of body-side engaging portions 220 are spaced apart in the vertical direction. The plurality of body-side engaging portions 220 are arranged at equal intervals. The intervals between the main body side engaging parts 220 are the same as the intervals between the leg side engaging parts 123. The main body side engaging parts 220 are provided at intervals of, for example, 0.3 cm to 3 cm (preferably 0.7 cm to 1.5 cm, for example 1 cm).

[0051] 6, the extension portion 222 is housed in a groove 236 formed in a second clamping member 232 (described later) of the clamping member 230. A stopper member 240 is detachably attached to the outside of the extension portion 222.

[0052] As shown in FIG. 6 , the clamping member 230 is a member capable of clamping the leg 100 from the side. The clamping member 230 has a first clamping member 231 and a second clamping member 232 that are divided in a cross section (vertical plane) along the longitudinal direction of the clamping member 230. The first clamping member 231 and the second clamping member 232 clamp the leg 100 from the side. The first clamping member 231 and the second clamping member 232 each include a first portion 233 that is inserted into the ring member 215 and a second portion 234 that is formed in a semicircular shape and has a male screw groove 237 formed on the outer circumferential surface. The first portion 233 is located above the second portion 234. A spring receiving recess 235 that holds a coil spring 238 is formed in the first portion 233 of the first clamping member 231. Coil spring 238 is provided between clamping member 230 and ring member 215, and biases ring member 215 outward. A groove 236 is formed in second portion 234 of second clamping member 232 to accommodate extension portion 222 of ring member 215. A locking claw 239 that locks onto leg support portion 55 is provided at the upper end of first portion 233.

[0053] As shown in FIG. 5, the stopper member 240 is formed in a ring shape. The leg body portion 121 of the leg 100 is inserted into the stopper member 240. An internal thread groove 242 is formed on the inner peripheral surface of the stopper member 240. The internal thread groove 242 is threadedly engaged with the external thread groove 237 of the clamping member 230. The stopper member 240 is a so-called nut. As shown in FIG. 6, when the internal thread groove 242 of the stopper member 240 is threadedly engaged with the external thread groove 237 of the clamping member 230, the leg body portion 121 of the leg 100 is clamped by the clamping member 230. Furthermore, when the internal thread 242 and the external thread groove 237 are threadedly engaged, the stopper member 240 is positioned outward of the extension portion 222 of the ring member 215, and therefore the adjustment button 218 does not move even when pressed. In other words, the stopper member 240 restricts the movement of the adjustment button 218. The position of the stopper member 240 when the stopper member 240 restricts the movement of the adjustment button 218 is referred to as a first position P1.

[0054] On the other hand, as shown in FIG. 12 , when the stopper member 240 is rotated relative to the clamping member 230 and removed from the clamping member 230, that is, when the female thread groove 242 of the stopper member 240 is not threadedly engaged with the male thread groove 237 of the clamping member 230, the leg body portion 121 of the leg 100 is not clamped by the clamping member 230. Furthermore, when the female thread 242 and the male thread 237 are not threadedly engaged, the stopper member 240 is not positioned outside the extension portion 222 of the ring member 215, and therefore can press the adjustment button 218. In other words, the stopper member 240 allows the adjustment button 218 to move. The position of the stopper member 240 when the stopper member 240 allows the adjustment button 218 to move is referred to as the second position P2. The stopper member 240 is provided so as to be movable between a first position P1 (see FIG. 6 ) and a second position P2. When the stopper member 240 is removed from the clamping member 230, the stopper member 240 is located above the first cylindrical portion .

[0055] The stepless adjustment mechanism 260 is a screw-type mechanism that rotates to steplessly adjust the leg length of the leg 100. As shown in FIG. 6, the stepless adjustment mechanism 260 is provided between the leg body 121 and the leg bottom 131. The stepless adjustment mechanism 260 steplessly adjusts the distance LS between the leg body 121 and the leg bottom 131. In FIG. 6, the distance LS between the leg body 121 and the leg bottom 131 is the smallest distance LSS. In FIG. 11, the distance LS between the leg body 121 and the leg bottom 131 is the largest distance LSL.

[0056] As shown in FIG. 5, the stepless adjustment mechanism 260 has a second cylindrical portion 262 formed in a cylindrical shape. The second cylindrical portion 262 has an outer peripheral wall 263 located on the outside, an inner peripheral wall 264 located inside the outer peripheral wall 263, and a connecting wall 265 (see FIG. 6) connecting the lower end of the outer peripheral wall 263 and the lower end of the inner peripheral wall 264. As shown in FIG. 6, the outer peripheral wall 263 extends in the vertical direction. The outer peripheral wall 263 is formed in a ring shape in a plan view. The inner peripheral wall 264 is inclined inward as it extends from the bottom to the top. The inner peripheral wall 264 is formed in a ring shape in a plan view. The vertical length of the inner peripheral wall 264 is shorter than the vertical length of the outer peripheral wall 263. The connecting wall 265 extends in the horizontal direction. A second screw groove 266 is formed on the inner circumferential surface of the outer peripheral wall 263. The second screw groove 266 is threadably engaged with the first screw groove 125 formed in the first cylindrical portion 124 of the leg body portion 121 .

[0057] As shown in FIG. 6, the second cylindrical portion 262 of the stepless adjustment mechanism 260 is configured to be rotatable relative to the first cylindrical portion 124 of the leg body 121. By rotating the second cylindrical portion 262 relative to the first cylindrical portion 124, the distance LS between the leg body 121 and the leg bottom 131 can be adjusted steplessly. For example, by rotating the second cylindrical portion 262 in a first direction relative to the first cylindrical portion 124, the distance LS between the leg body 121 and the leg bottom 131 can be increased (see FIG. 11). On the other hand, by rotating the second cylindrical portion 262 in a second direction opposite to the first direction relative to the first cylindrical portion 124, the distance LS between the leg body 121 and the leg bottom 131 can be decreased (see FIG. 6). The distance LS between the leg body 121 and the leg bottom 131 is, for example, in the range from 0 mm to the vertical distance (hereinafter referred to as the pitch width) of the leg-side engagement portion 123 of the stepped adjustment mechanism 210. The distance LS is, for example, in the range from the minimum distance (e.g., several mm) between the leg body 121 and the leg bottom 131 to a value larger than the pitch width. The distance LS can be adjusted to a value larger than the pitch width. The second tubular portion 262 of the stepless adjustment mechanism 260 is inserted into the protruding member 135 of the leg bottom 131, but the second tubular portion 262 is not connected to the protruding member 135, and therefore the second tubular portion 262 can rotate around the protruding member 135 relative to the protruding member 135. Therefore, even if the second cylindrical portion 262 is rotated, the protruding member 135 does not rotate, and the orientation of the leg bottom portion 131 does not change (the second leg surface 142 is always positioned in front of the first leg surface 141). In this way, in this embodiment, the leg bottom portion 131 is configured not to rotate when the stepless adjustment mechanism 260 is rotated.

[0058] FIG. 8 shows the portable toilet 10 in its normal state, with the toilet body 50 not tilted. FIG. 9 shows the portable toilet 10 in its tilted state, with the toilet body 50 tilted forward. That is, the seat surface 21 of the toilet seat 20 (see FIG. 2) is tilted downward toward the front compared to its normal state. When using the portable toilet 10 in its tilted state, the leg length adjustment mechanisms 200 of the front legs 110F and the rear legs 110Rr can be adjusted appropriately to increase the height from the first leg surface 141 of the rear legs 110Rr to the toilet seat 20 by a few centimeters (e.g., 1 cm to 5 cm, e.g., 2 cm) compared to the height from the first leg surface 141 of the front legs 110F to the toilet seat 20. In this state, as shown in FIG. 9, the second leg surface 142 of the front legs 110F and the second leg surface 142 of the rear legs 110Rr come into surface contact with the floor surface MM.

[0059] The portable toilet 10 of this embodiment is made of a resin material. That is, the lid 15, toilet seat 20, receiving plate 30, bucket 40, toilet body 50, backrest 70, armrests 80, and legs 100 are made of a resin material. As the resin material, from the viewpoints of stain resistance (wipeability), rigidity, impact resistance, and moldability, for example, polypropylene resin, ABS resin, polyvinyl chloride resin, polycarbonate resin, polyester resin, etc. can be used. In particular, from the viewpoint of moldability, polypropylene resin and ABS resin can be preferably used. Each of the above components is manufactured by, for example, injection molding.

[0060] As described above, according to the portable toilet 10 of this embodiment, the front legs 110F and the rear legs 110Rr have first leg surfaces 141 that come into surface contact with the floor when the toilet body 50 is not tilted. Therefore, when a user uses the toilet body 50 in a state where it is not tilted (i.e., under normal circumstances), the first leg surfaces 141 come into surface contact with the floor, thereby stabilizing the toilet body 50. Furthermore, the front legs 110F and the rear legs 110Rr have second leg surfaces 142 that come into surface contact with the floor when the toilet body 50 is tilted. Therefore, when a user uses the toilet body 50 in a state where it is tilted, the second leg surfaces 142 come into surface contact with the floor, thereby stabilizing the toilet body 50. In this way, whether the toilet body 50 is not tilted or tilted, the toilet body 50 is stably positioned on the floor, allowing the user to use the portable toilet 10 comfortably.

[0061] In the portable toilet 10 of this embodiment, the angle between the first leg surface 141 and the floor surface and the angle between the second leg surface 142 and the floor surface are different, so that when the difference between the leg lengths of the rear legs 110Rr and the front legs 110F is a first length, the first leg surface 141 comes into surface contact with the floor surface, and when the difference between the leg lengths of the rear legs 110Rr and the front legs 110F is a second length that is longer than the first length, the second leg surface 142 comes into surface contact with the floor surface. With this configuration, the leg surface that comes into surface contact with the floor surface can be changed depending on the leg length of the rear legs 110Rr, so the toilet body 50 can be placed stably on the floor surface.

[0062] In the portable toilet 10 of this embodiment, the first leg surface 141 is a horizontal surface, and the second leg surface 142 is an inclined surface. With this configuration, the toilet body 50 can be stably placed on the floor.

[0063] In the portable toilet 10 of this embodiment, the front legs 110F are configured to be adjustable in leg length, which is the length that they extend from the toilet body 50. With this configuration, the height of the toilet body 50 from the floor can be adjusted, allowing the user to use the portable toilet 10 more comfortably.

[0064] In the portable toilet 10 of this embodiment, the angle difference between the first leg surface 141 and the second leg surface 142 is 10° or less. With this configuration, the toilet body 50 does not tilt excessively, allowing the user to use the portable toilet 10 comfortably.

[0065] In the portable toilet 10 of this embodiment, the area of ​​the first leg surface 141 is larger than the area of ​​the second leg surface 142. With this configuration, the toilet body 50 can be stably supported by the legs 100 during normal use when the toilet is used frequently (i.e., when the toilet body 50 is not tilted).

[0066] In the portable toilet 10 of this embodiment, the area of ​​the first leg surface 141 of the rear leg 110Rr is larger than the area of ​​the first leg surface 141 of the front leg 110F. When a user sits on the toilet body 50, a large load is normally applied to the rear leg 110Rr, so by making the area of ​​the first leg surface 141 of the rear leg 110Rr larger, the toilet body 50 can be more stably supported by the rear leg 110Rr.

[0067] In the portable toilet 10 of this embodiment, the area of ​​the second leg surface 142 of the rear leg 110Rr is larger than the area of ​​the second leg surface 142 of the front leg 110F. When the toilet body 50 is tilted, the toilet body 50 becomes more stable by increasing the area of ​​the second leg surface 142 of the rear leg 110Rr.

[0068] Although the preferred embodiments of the present invention have been described above, the above-described embodiments are merely examples, and the present invention can be embodied in various other forms.

[0069] In the above-described embodiment, the stepless adjustment mechanism 260 is provided only on the front leg 110F, but this is not limited to this. The stepless adjustment mechanism 260 may be provided only on the rear leg 110Rr. Furthermore, the stepless adjustment mechanism 260 may be provided on both the front leg 110F and the rear leg 110Rr. Furthermore, the portable toilet 10 does not have to be provided with the stepless adjustment mechanism 260.

[0070] In the above-described embodiment, the stepless adjustment mechanism 260 is a screw-type mechanism that rotates to steplessly adjust the leg length of the leg 100, but is not limited to this. The stepless adjustment mechanism 260 may also be a mechanism that steplessly adjusts the leg length of the leg 100 by a method other than rotation. The stepless adjustment mechanism 260 may be, for example, a mechanism that causes the leg body 121 to slide up and down relative to the leg bottom 131, and may also be a mechanism that fastens the leg body 121 and the leg bottom 131 with a screw.

[0071] In the embodiment described above, the stepped adjustment mechanism 210 engages and disengages the leg-side engagement portion 123 and the main body-side engagement portion 220 by pressing the adjustment button 218, but is not limited to this. Instead of the adjustment button 218, the engagement and disengagement between the leg-side engagement portion 123 and the main body-side engagement portion 220 may be performed by using another structure such as a lever.

[0072] In the above-described embodiment, the casters 115 for movement are provided on the rear legs 110Rr, but they may also be provided on the front legs 110F.

[0073] A cushion made of a foamed soft resin material may be placed on the surface of the seat 21 of the toilet seat 20 (the surface on which the user sits).

[0074] The grip member 138 of the leg bottom 131 may have another leg surface in addition to the first leg surface 141 and the second leg surface 142. When the grip member 138 has a third leg surface as the other leg surface, for example, the front leg 110F is longer than the rear leg 110Rr, and the third leg surface is formed so as to come into surface contact with the floor surface when the toilet body 50 is installed with a rearward tilt of 3°.
