Description

The present invention relates to a bucket for a portable toilet that is detachably attached to the toilet body of the portable toilet and a portable toilet provided with the bucket.

For example, as disclosed in Patent Document 1, the portable toilet includes a removable bucket arranged below the toilet seat. After using the portable toilet, the user or a caregiver (hereinafter collectively referred to as a user) removes the bucket from the bucket body and carries it to a sewage discharge place such as a toilet. Then, the user discharges the sewage collected in the bucket to the toilet bowl or the like of the toilet.

The bucket has a container and a handle that spans the top of the container. The user can remove the bucket by lifting the handle. In addition, the user can carry the bucket by moving while grasping the handle. When removing and carrying the bucket, the handle is held upright, but when using a portable toilet, the handle is tilted out of the way. Therefore, the handle is rotatably assembled with respect to the container.

However, if the handle is rotatable, the container may shake and sewage may be scattered to the outside when the user grabs the handle and carries the bucket. In addition, if the container hits furniture or the like during transportation, the container may tilt and sewage may spill.

Therefore, the inventor of the present application has considered providing a mechanism (hereinafter referred to as a lock mechanism) for fixing the bucket for a portable toilet so that it does not rotate with respect to the container when the handle is lifted. For example, Patent Document 2 discloses a bucket provided with such a locking mechanism, although it is not for a portable toilet.

Japanese Patent No. 6317893 Jikken Sho 54-148540

When draining sewage from a bucket to a toilet bowl or the like, the user tilts the container while grasping the handle. In a conventional bucket, the user grabs the handle with one hand, grabs the bottom of the back of the bucket with the other, and tilts the container forward.

However, the user had to bend down to grasp the bottom of the rear side of the bucket, which was a heavy work load. Also, in a bucket in which the handle is non-rotatably fixed to the container, tilting the container forward causes the handle to move forward. The work load was heavy because the distance between one hand holding the handle and the other hand holding the bottom of the back of the bucket was large.

An object of the present invention is a portable toilet bucket in which the handle is fixed so as not to rotate with respect to the container when the handle is lifted, and the work load is small when the container is tilted while grasping the handle to discharge sewage. It is to provide a portable toilet equipped with it.

The bucket for a portable toilet according to the present invention has a container having an upper edge opening upward, a handle that is rotatably engaged with the container from the left side portion to the right side portion of the container, and the handle. It is provided with a lock mechanism for fixing the handle to the container so as not to rotate when it is lifted upright. The upper edge portion of the container has an inner peripheral wall, an upper wall extending outward from the upper end of the inner peripheral wall, and an outer peripheral wall extending downward from the outer end of the upper wall. A handle protruding rearward is provided on the rear side of the upper edge portion and in the central portion in the left-right direction. The handle has a curved curved wall extending rearward and downward from the lower end of the outer peripheral wall, a horizontal wall extending rearward from the rear end of the curved wall, and a vertical wall extending downward from the rear end of the lateral wall. is doing. The left and right length of the handle is 35 mm or more, and the vertical length of the vertical wall is 2 mm or more.

According to the above-mentioned portable toilet bucket, the user can tilt the container forward by grasping the handle with one hand and hooking the other hand on the handle and lifting it, and draining sewage from the container. Can be done. The handle is provided on the rear side of the upper edge of the container and in the central portion in the left-right direction, and is arranged at a relatively high position. Therefore, the user can hook his / her finger on the handle without bending down. Also, the distance between one hand that grabs the handle and the other hand that hooks the finger on the handle does not increase. Further, since the left and right length of the handle is 35 mm or more, the user can hook at least three fingers on the handle. Further, since the vertical length of the vertical wall is 2 mm or more, it is easy to catch a finger on the vertical wall. Further, a curved wall is provided between the outer peripheral wall of the container and the side wall of the handle. Therefore, the tip of the finger is less likely to hurt when the finger is hooked on the handle, as compared with the case where the corner portion is formed between the outer peripheral wall of the container and the side wall of the handle. Therefore, according to the portable toilet bucket, it is possible to reduce the work load on the user when the container is tilted to discharge sewage.

The handle may have a curved wall, a lateral wall, and left and right walls arranged to the left and right of the vertical wall, respectively.

This prevents the left and right walls from shifting the finger hooked on the handle to the left or right. Therefore, the work of lifting the handle and tilting the container forward becomes easy.

The horizontal wall may extend in the horizontal direction, and the vertical wall may extend in the vertical direction.

This facilitates the work of lifting the handle and tilting the container forward.

By the way, dirt may adhere to the outer wall of the container. If the handle comes into contact with the outer wall of the container when the handle is rotated backward, the handle may become dirty. Therefore, the handle may be configured so that the handle can be placed on the handle when the handle is tilted backward.

This allows the handle to be supported by the handle when it is tilted backwards. Since the handle is prevented from coming into contact with the outer wall of the container, it is possible to prevent the handle from becoming dirty.

A shaft hole that engages with the handle may be formed on the left side portion and the right side portion of the upper edge portion of the container. The anteroposterior length between the front end of the container and the shaft hole may be longer than the anteroposterior length between the rear end of the container and the shaft hole.

This facilitates the work of holding the handle and tilting the container forward.

The bottom wall of the container may be inclined so as to go upward toward the front.

In a portable toilet, water is stored in a bucket so that the water level reaches a predetermined level before use. According to the above items, it is easy to secure the water level in the container even if the amount of water is relatively small. Therefore, water can be saved.

The upper edge portion of the container may have a liquid drain plate protruding forward from the front portion of the outer peripheral wall.

As a result, when the container is tilted and the sewage is discharged, the sewage flows down from the tip of the drain plate. It is suppressed that sewage is transmitted to the front surface of the outer peripheral wall, and that dirt is prevented from adhering to the outer wall of the container. Therefore, it is possible to prevent the outer wall of the container from becoming dirty.

A downwardly recessed spout may be formed at the front end of the upper edge of the container.

This allows the sewage to be drained intensively from the spout when the container is tilted. Therefore, it is possible to prevent the sewage from scattering to the left and right, and the sewage can be satisfactorily discharged from the container to the toilet bowl.

The container may have a circular bottom wall when viewed from above, and a peripheral wall extending upward from the bottom wall. The peripheral wall may have a posterior peripheral wall having an arcuate horizontal cross section and a front peripheral wall extending forward from the posterior peripheral wall and having a convex horizontal cross section forward. The front peripheral wall may have a lower wall portion, a left wall portion extending upward from the left end of the lower wall portion, and a right wall portion extending upward from the right end of the lower wall portion. The lower wall portion, the left wall portion, and the right wall portion may form a flow path extending back and forth when viewed from above. The left-right width of the flow path may be larger than half the radius of the bottom wall.

As a result, when the container is tilted, sewage can be discharged through the flow path. The left-right width of the flow path is more than half the radius of the bottom wall and is relatively large. Even when the container is tilted relatively large in order to discharge the sewage quickly, the sewage does not spread laterally beyond the flow path, and it is possible to prevent the sewage from splashing out of the toilet bowl or the like. The sewage in the container can be discharged in a relatively short time, and the work load on the user can be reduced.

The portable toilet according to the present invention is provided with the bucket for the portable toilet described above.

According to the present invention, a portable toilet bucket and a bucket in which the handle is fixed so as not to rotate with respect to the container when the handle is lifted, and the work load is small when the container is tilted while grasping the handle to discharge sewage. A portable toilet equipped with it can be provided.

The handle 50 is bridged from the left side portion to the right side portion of the container 20. The handle 50 is bridged over the container 20 so as to straddle the upper edge portion 22. Although the details will be described later, the handle 50 is rotatably engaged with the container 20 around the axis C1.

<Container>
3, FIG. 4, FIG. 5, and FIG. 6 are a plan view, a left side view, a rear view, and a bottom view of the container 20, respectively. FIG. 7 is a vertical sectional view of the container 20, and is a sectional view taken along line VII-VII of FIG. FIG. 8 is a horizontal sectional view of the container 20, and is a sectional view taken along line VIII-VIII of FIG. As shown in FIG. 7, the container 20 is provided on the bottom wall 24, the peripheral wall 26 extending upward from the bottom wall 24, the upper edge portion 22 located above the peripheral wall 26, and the lower side of the bottom wall 24. It is provided with an annular leg 28.

As shown in FIG. 3, the bottom wall 24 is formed in a circular shape when viewed from above. As shown in FIG. 7, the bottom wall 24 is formed in a concave shape recessed downward. In the present embodiment, the bottom wall 24 has a horizontal wall 24A that extends horizontally and is circular when viewed from above, and a sloping wall 24B that is inclined diagonally upward from the outer peripheral end of the horizontal wall 24A.

However, the shape of the bottom wall 24 is not particularly limited. As shown in FIG. 9, the bottom wall 24 may be curved in a concave shape. The bottom wall 24 may be formed so as not to have a bent portion. Also in this case, the bottom wall 24 is formed in a circular shape when viewed from above. The bottom wall 24 may be formed in a hemispherical shape.

As shown in FIG. 10, the bottom wall 24 may be inclined so as to go upward toward the front. In this case as well, the bottom wall 24 may be formed in a circular shape when viewed from above.

As shown in FIG. 8, the peripheral wall 26 has a posterior peripheral wall 26A having an arcuate horizontal cross section and a front peripheral wall 26B extending forward from the posterior peripheral wall 26A and having a horizontal cross section convex forward. As shown in FIG. 4, when viewed from the side, the contour of the front peripheral wall 26B has a portion 26BL that is curved so that the inclination angle α with respect to the horizon becomes smaller toward the upper side. The ratio of the curved portion 26BL to the entire contour of the front peripheral wall 26B is not particularly limited, but is preferably 50% or more, and more preferably 65% or more. In this embodiment, it is 80% or more. The entire contour of the front peripheral wall 26B may be the curved portion 26BL.

As shown in FIG. 7, an upper vertical wall 26BU is provided above the portion 26BL that is curved so that the inclination angle α with respect to the horizon becomes smaller toward the upper side. The upper vertical wall 26BU is a substantially vertical wall. The upper vertical wall 26BU may extend vertically or may be slightly tilted from the vertical plane. For example, the upper vertical wall 26BU may be tilted at an angle within ± 10 degrees, preferably within ± 5 degrees from the vertical plane. The upper vertical wall 26BU serves to prevent urine from splashing in front of the container 20 due to the force of urination when the portable toilet 1 is used. From the viewpoint of preventing urine from scattering, the vertical dimension of the upper vertical wall 26BU is preferably 3 mm or more, and more preferably 8 mm or more. On the other hand, if the vertical dimension of the upper vertical wall 26BU is large, when the container 20 is tilted forward to discharge the sewage after using the portable toilet 1, the last remaining sewage jumps in front of the upper vertical wall 26BU. It tends to hit the upper vertical wall 26BU and easily pop out. From the viewpoint of preventing such sewage from scattering, the vertical dimension of the upper vertical wall 26BU is preferably 30 mm or less, more preferably 20 mm or less. If the vertical dimension of the vertical vertical wall 26BU is set to 17 mm or less, it is possible to further prevent the sewage from spilling out.

FIG. 11 is a vertical sectional view of the front peripheral wall 26B, and is a sectional view taken along line XI-XI of FIG. The vertical cross section shown in FIG. 11 is a vertical cross section of the front peripheral wall 26B at an intermediate position between the rear end 26Bb of the front peripheral wall 26B and the front end 20f of the container 20. As shown in FIG. 11, the front peripheral wall 26B includes a lower wall portion 27D, a left wall portion 27L extending upward from the left end of the lower wall portion 27D, and a right wall portion 27R extending upward from the right end of the lower wall portion 27D. Have. As shown in FIG. 3, the lower wall portion 27D, the left wall portion 27L, and the right wall portion 27R form a flow path 27 extending back and forth when viewed from above.

The left and right widths W27 of the flow path 27 are relatively large. The left and right width W27 of the flow path 27 referred to here is the left and right width in the cross section of the flow path 27 (the cross section at the intermediate position between the rear end 26Bb of the front peripheral wall 26B and the front end 20f of the container 20). be. The left and right width W27 of the flow path 27 is larger than half of the radius r24 of the bottom wall 24. Further, the left and right width W27 of the flow path 27 is larger than the radius r24A of the horizontal wall 24A of the bottom wall 24. Here, the left and right width W27 of the flow path 27 is larger than the radius r24 of the bottom wall 24. Further, the left and right width W27 of the flow path 27 is larger than the radius r28 (see FIG. 6) of the annular leg 28. The radius of the annular leg 28 means 1/2 of the inner diameter of the annular leg 28. The annular leg 28 is formed in a substantially annular shape when viewed from below. The substantially annular shape includes a shape that circulates around the center 24C of the bottom wall 24 (that is, a strict annular shape) and a shape in which a cut 28a is provided in a part of the annular shape as shown in FIG.

The upper limit of the width W27 on the left and right of the flow path 27 is not particularly limited, but is preferably 170 mm or less, for example. This makes it easier to pour sewage into a relatively small reservoir of a standard Japanese style toilet at once without overflowing.

In the portable toilet 1, it is recommended to store a predetermined volume of water in the bucket 10 before use. As shown in FIG. 7, the peripheral wall 26 is provided with a step 25 as a mark indicating the position of the water surface when a predetermined volume of water is stored in the container 20. Here, the step 25 is provided at the position of the water surface when a volume of water of 1 liter is stored in the container 20. Since a sufficient water level can be secured by storing 1 liter of water, the stool is usually submerged in water and the generation of odor can be suppressed. Although the step 25 is provided on the rear peripheral wall 26A, it may be provided on the front peripheral wall 26B. The mark may be visible and is not limited to the step 25. As a mark, a groove, a protrusion, or the like may be used instead of the step 25. Further, colored lines, figures, characters, symbols and the like may be used as marks. However, it is particularly preferable to use the step 25 as a mark because visibility can be ensured even if dirt is accumulated and it does not disappear even after long-term use.

As shown in FIG. 7, the upper edge portion 22 has an inner peripheral wall 22A located above the peripheral wall 26, an upper wall 22B extending outward from the upper end of the inner peripheral wall 22A, and an outer peripheral extending downward from the outer end of the upper wall 22B.

As shown in FIG. 16, the handle 50 has a handle portion 51 and engaging portions 52 provided at both ends of the handle portion 51. The engaging portion 52 is a portion that engages with the shaft hole 30 of the container 20. As shown in FIG. 17, the engaging portion 52 extends inward from the tip end portion of the handle portion 51. The engaging portion 52 has a shaft 54, a stopper 56 provided inside the shaft 54, and a reinforcing portion 58 provided outside the shaft 54. The stopper 56 is provided on the tip end side of the shaft 54. Specifically, the engaging portion 52 on the right side of the handle 50 has a reinforcing portion 58, a shaft 54 provided on the left side of the reinforcing portion 58, and a stopper 56 provided on the left side of the shaft 54. .. The engaging portion 52 on the left side of the handle 50 has a reinforcing portion 58, a shaft 54 provided on the right side of the reinforcing portion 58, and a stopper 56 provided on the right side of the shaft 54.

The shaft 54 is formed in a square columnar shape. As shown in FIG. 18, the cross-sectional shape of the shaft 54 is formed in a square shape. The square shape referred to here is not limited to a strict square shape having right-angled corners, but also includes a square shape having rounded corners as shown in FIG. The shaft 54 is a third shaft connecting a first shaft edge 54a, a second shaft edge 54b located on the opposite side of the first shaft edge 54a, one end of the first shaft edge 54a, and one end of the second shaft edge 54b. It has an edge 54c and a fourth axis edge 54d connecting the other end of the first axis edge 54a and the other end of the second axis edge 54b. The length of the first shaft edge 54a and the second shaft edge 54b is longer than the length of the third shaft edge 54c and the fourth shaft edge 54d.

Since the handle 50 rotatably engages with the container 20, the handle 50 can be tilted forward as shown in FIG. Further, as shown in FIG. 20, the handle 50 can be raised. Further, as shown in FIG. 21, the handle 50 can be tilted backward. When the handle 50 is tilted backward, the handle 50 is placed on the side wall 42 of the handle 40. When the handle 50 is tilted backward, the handle 50 is supported by the handle 40.

The shaft 54 is inserted into the shaft hole 30. The shaft 54 is formed in a size that can be rotated in the circular hole 31. The maximum dimension L54 (here, diagonal dimension; see FIG. 18) of the cross section of the shaft 54 is smaller than the inner diameter of the circular hole 31. When the shaft 54 is in the circular hole 31, the handle 50 can be rotated. When the handle 50 is tilted, the shaft 54 is arranged in the circular hole 31.

When the handle 50 is raised and lifted (see FIG. 20), as shown in FIG. 22, the shaft 54 moves from the circular hole 31 to the vertical hole 32 and fits into the vertical hole 32. When the shaft 54 is fitted into the vertical hole 32, the rotation of the shaft 54 is restricted by the vertical hole 32. Therefore, when the handle 50 is raised and lifted, the handle 50 becomes non-rotatable. The shaft 54 and the vertical hole 32 constitute a lock mechanism 55 that rotatably fixes the handle 50 to the container 20 when the handle 50 is raised and lifted.

When the shaft 54 is fitted into the vertical hole 32, the first shaft edge 54a faces the leading edge 32f of the vertical hole 32, and the second shaft edge 54b faces the trailing edge 32b of the vertical hole 32. The third shaft edge 54c abuts on the upper edge 32t of the vertical hole 32. The hole width W32 (see FIG. 12) of the vertical hole 32 is equal to the length H54c of the third shaft edge 54c, or slightly larger than the length H54c of the third shaft edge 54c. The vertical length H32f of the leading edge 32f of the vertical hole 32 is longer than the length H54a of the first shaft edge 54a. The vertical length H32b of the trailing edge 32b of the vertical hole 32 is shorter than the length H54a of the first shaft edge 54a.

As shown in FIG. 18, the reinforcing portion 58 is formed in a square columnar shape like the shaft 54. The cross-sectional shape of the reinforcing portion 58 is formed in a square shape slightly larger than the shaft 54. As shown in FIG. 22, when the shaft 54 is fitted into the vertical hole 32, the reinforcing portion 58 is inserted inside the reinforcing rib 34. The reinforcing portion 58 fits inside the reinforcing rib 34 and comes into contact with the reinforcing rib 34.

As shown in FIG. 17, the stopper 56 has a disk-shaped stopper main body portion 56A and a protrusion 56B protruding from the stopper main body portion 56A. The stopper 56 is formed in a b shape when viewed from the axial direction of the shaft 54. The stopper 56 is provided to prevent the engaging portion 52 of the handle 50 from coming off the shaft hole 30. 23 to 25 are views schematically showing the shaft hole 30, the stopper 56, and the shaft 54 when viewed from the axial direction of the shaft 54. 23 to 25 are views of the outer peripheral wall 22C on the right side of the container 20 viewed from the back side (in other words, a view of the outer peripheral wall 22C on the right side of the container 20 viewed from the left side to the right).

As shown in FIG. 23, when the handle 50 is tilted, at least a part of the stopper main body portion 56A is located inside the circular hole 31 when viewed from the axial direction. The stopper main body 56A may be formed in a circular shape having an outer diameter equal to or smaller than the inner diameter of the circular hole 31 when viewed from the axial direction, but here, the circle having an outer diameter slightly larger than the inner diameter of the circular hole 31. It is formed in a shape. The outer diameter D56A of the stopper main body 56A is larger than the hole width W32 of the vertical hole 32.

When the handle 50 is tilted backward as shown in FIG. 21, the protrusion 56B projects upward from the stopper main body 56A when viewed from the axial direction as shown in FIG. 23. When the handle 50 is tilted backward, the protrusion 56B is located inside the vertical hole 32 when viewed from the axial direction. The container 20 is made of resin and has elasticity. When the stopper 56 is inserted into the shaft hole 30 with the handle 50 tilted backward, the circular hole 31 is temporarily expanded by the stopper main body portion 56A. Therefore, the stopper main body portion 56A can pass through the circular hole 31. Further, since the protrusion 56 is located inside the vertical hole 32, the protrusion 56 can pass through the vertical hole 32 as it is. Therefore, by pressing the stopper 56 against the shaft hole 30 from the front side with the handle 50 tilted backward, the stopper 56 can be arranged on the back side of the shaft hole 30 (in other words, inside the outer peripheral wall 22C).

As shown in FIG. 24, when the handle 50 is rotated from the tilted state, the protrusion 56B moves to the outside of the shaft hole 30 when viewed from the axial direction. The protrusion 56B overlaps with the peripheral portion of the shaft hole 30 of the outer peripheral wall 22C when viewed from the axial direction. When the protrusion 56B comes into contact with the peripheral portion of the shaft hole 30, the handle 50 is restricted from being displaced in the axial direction, and the handle 50 is prevented from coming out of the shaft hole 30.

When the handle 50 is raised and lifted as shown in FIG. 20, the shaft 54 moves from the circular hole 31 to the vertical hole 32 as shown in FIG. 25. The protrusion 56B is located in front of the vertical hole 32 when viewed from the axial direction. Also in this case, the protrusion 56B overlaps with the peripheral portion of the shaft hole 30 of the outer peripheral wall 22C when viewed from the axial direction. Therefore, the handle 50 is prevented from coming out of the shaft hole 30.

After using the portable toilet 1, the user removes the bucket 10 from the toilet body 2 by raising and lifting the handle 50. In addition, the user carries the bucket 10 to the toilet by moving while grasping the handle 50. As described above, in the container 20, the length L20f of the front portion of the shaft hole 30 is longer than the length L20b of the rear portion of the shaft hole 30 (see FIG. 4). However, the front peripheral wall 26B is inclined forward and diagonally upward when viewed from the side. The container 20 is formed so that when a predetermined amount or less of water is stored, the position of the container 20 and the center of gravity of the entire water in the front-rear direction is located in the vicinity of the shaft hole 30 regardless of the water level. That is, the container 20 is formed so that the total center of gravity of the container 20 and the water is substantially located directly below the shaft hole 30 when water of a predetermined volume or less is stored, and the container 20 is formed before and after the center of gravity even if the water level changes. It is formed so that the fluctuation of the position is small.

If the storage amount of the container 20 is too large, it becomes difficult to carry the bucket 10. Therefore, in the portable toilet 1, the upper limit of the storage volume of the container 20 is often set in advance. The predetermined volume may be equal to, for example, the upper limit of the storage volume of the container 20. However, it is not limited. The predetermined volume may be smaller than the upper limit of the storage volume of the container 20. Here, as shown in FIG. 20, when water of 50% or less of the internal volume of the container 20 is stored in the container 20, the position of the container 20 and the center of gravity of the entire water in the front-rear direction is not related to the water level. It is formed so as to be located between a position P1 10 mm forward from the front end of the shaft hole 30 and a position P2 10 mm rearward from the rear end of the shaft hole 30.

As described above, the bucket 10 is formed so that the front-back position of the center of gravity does not fluctuate even if the water level changes. However, when the bucket 10 is removed from the toilet body 2 or transported, the bucket 10 shakes. Or it may tilt by touching furniture. Depending on the shape of the container 20, the center of gravity may move to the tilted side, and gravity may act to promote the tilt. In that case, the inclination becomes large, and a phenomenon that sewage spills from the container 20 may occur. For example, there is a case where there is a pool corner shape in which water can collect on the inclined side at a position away from the vertical plane passing through the axis C1 (see FIG. 2) of the shaft hole 30. However, the above phenomenon can be avoided by devising the shape of the container 20 so as to reduce the volume of water accumulated on the inclined side. For example, by making an angle to the bottom so as to reduce the angle between the bottom and the front and rear walls, which is the corner of the pool, making a curved surface or a spherical surface between the bottom and the front and rear walls, or making the bottom deeper, the above phenomenon occurs. Can be avoided.

In this embodiment, the container 20 is formed as follows. In FIGS. 26 (a) to 26 (c), the vertical line VP represents a vertical plane passing through the axis line C1 of the shaft hole 30. The angle θ represents the tilt angle of the container 20 with respect to the horizontal plane. The symbol G represents the position of the center of gravity of the container 20 and the entire water. In the present embodiment, when water of 50% or less of the internal volume of the container 20 is stored in the container 20, at least the container 20 is larger than 0 degrees with respect to the horizontal plane as shown in FIG. 26 (b). Moreover, the center of gravity G is formed so as to be located in front of the vertical VP when the center of gravity G is tilted backward at an angle θ of less than 20 degrees. Further, in the container 20, when water of 50% or less of the internal volume of the container 20 is stored, at least the container 20 is larger than 0 degrees and 20 degrees with respect to the horizontal plane, as shown in FIG. 26 (c). The center of gravity G is formed so as to be located behind the vertical VP when tilted forward at an angle θ less than.

According to the present embodiment, when removing or transporting the bucket 10 from the toilet body 2, gravity acts to restore the tilt, at least when the container 20 is tilted at an angle of less than 20 degrees. Therefore, it is prevented that the inclination becomes large, and sewage is suppressed from spilling from the container 20. Even when the container 20 is tilted at an angle of 20 degrees or more, the container 20 may be configured such that gravity acts so as to return the tilt.

The above is the configuration of the portable toilet 1 and the bucket 10 according to the present embodiment. Next, an example of how to use the bucket 10 will be described.

<How to use the bucket>
When the user uses the portable toilet 1, sewage collects in the bucket 10. In order to dispose of the sewage in the bucket 10, the user first removes the bucket 10 from the toilet body 2 by raising the handle 50 upright. At this time, the shaft 54 of the handle 50 is fitted into the vertical hole 32 of the container 20, and the handle 50 is fixed to the container 20 so as not to be rotatable. Therefore, the user can easily remove the bucket 10.

Next, the user moves to the toilet while grasping the handle 50. At this time, since the handle 50 is fixed to the container 20 so as not to be rotatable, the container 20 is suppressed from shaking. Further, even if the container 20 hits furniture or the like during transportation, it does not tilt significantly. Therefore, it is possible to prevent sewage from spilling while carrying the bucket 10.

After arriving at the toilet, the user discharges the sewage from the bucket 10 to the toilet bowl of the toilet. The operation of discharging sewage from the bucket 10 to the toilet bowl will be described with reference to FIGS. 27 to 29. 27 (a), 28 (a), and 29 (a) are side views schematically showing a bucket and a toilet bowl, and FIGS. 27 (b), 28 (b), and 29 (b) are views. , A shaft and a shaft hole are schematically shown.

As shown in FIG. 27 (a), the user hooks the other hand h2 on the handle 40 of the container 20 from below while grasping the handle 50 with one hand h1 above the toilet bowl 60. Then, by lifting the handle 40, the container 20 is tilted forward together with the handle 50.

As shown in FIG. 28 (a), by gradually increasing the inclination of the container 20, the sewage in the container 20 is quickly discharged to the toilet bowl. At this time, as shown in FIG. 28 (b), the shaft 54 of the handle 50 is pushed from the peripheral portion of the vertical hole 32, and a force (see arrow A1) that tilts from the vertical hole 32 acts on the shaft 54. However, since the vertical length of the leading edge 32f of the vertical hole 32 is longer than the length of the first shaft edge 54a of the shaft 54, even if the shaft 54 is tilted, the lower end portion 54ad of the first shaft edge 54a is the vertical hole 32. It remains supported by the leading edge 32f of. Therefore, the shaft 54 is prevented from coming off the vertical hole 32.

Therefore, as shown in FIGS. 29 (a) and 29 (b), even if the container 20 is tilted greatly, the shaft 54 does not come off from the vertical hole 32 and the handle 50 is not released from the fixing. The container 20 can be tilted as intended by the user while the handle 50 is maintained in a fixed state. If the handle 50 is unintentionally released while the container 20 is tilted, the container 20 may be tilted at once, and sewage may be rapidly discharged and scattered outside the toilet bowl 60. However, according to this embodiment, such a thing can be prevented.

After draining the sewage from the container 20 as described above, the user cleans the bucket 10. At this time, for example, the bucket 10 is placed on a sink or the floor of a bathtub, and the handle 50 is tilted backward. As a result, the inside of the container 20 can be cleaned without being disturbed by the handle 50.

After cleaning the bucket 10, the user stores a predetermined volume of water in the container 20. Then, the handle 50 is raised and lifted, the bucket 10 is carried while grasping the handle 50, and the bucket 10 is attached to the toilet body 2. After that, the handle 50 is tilted backward and the toilet seat 5 (see FIG. 1) is tilted forward. As a result, the portable toilet 1 becomes available again. The work of storing water in the container 20 is not limited to before the bucket 10 is attached to the toilet body 2, but may be performed after the bucket 10 is attached to the toilet body 2.

The above is an example of how to use the bucket 10. Here, the sewage of the bucket 10 is discharged to the toilet bowl 60 of the toilet, but the discharge location of the sewage is not limited to the toilet bowl of the toilet.

<Effect of embodiment>
Next, various effects brought about by this embodiment will be described.

According to the bucket 10 according to the present embodiment, as shown in FIG. 27 (a), the user grabs the handle 50 with one hand h1 and hooks the other hand h2 on the handle 40 to lift it. As shown in FIG. 28A, the container 20 can be tilted forward, and sewage can be discharged from the container 20 to the toilet bowl 60. The handle 40 is provided on the rear side of the upper edge portion 22 of the container 20 and in the central portion in the left-right direction, and is arranged at a relatively high position. Therefore, the user can hook his / her finger on the handle 40 without bending down. Further, in the bucket 10, when the handle 50 is being lifted, the handle 50 is fixed to the container 20, so that when the container 20 is tilted forward, the handle 50 moves forward. However, according to the present embodiment, one hand h1 that grips the handle 50 and the other hand h2 that hooks a finger on the handle 40 are compared with the case where the other hand h2 grips the bottom of the rear side of the container 20. The interval between is not large. Further, since the left and right lengths of the handle 40 are 35 mm or more, the user can hook at least three fingers on the handle 40. Further, since the vertical length of the vertical wall 43 of the handle 40 is 2 mm or more, it is easy to hook a finger on the vertical wall 43. Further, a curved wall 41 is provided between the outer peripheral wall 22C of the container 20 and the side wall 42 of the handle 40 (see FIG. 14). Therefore, the tip of the finger is less likely to hurt when the finger is hooked on the handle 40, as compared with the case where the corner portion is formed between the outer peripheral wall 22C of the container 20 and the side wall 42 of the handle 40. Therefore, according to the bucket 10 according to the present embodiment, it is possible to reduce the work load on the user when the container 20 is tilted forward to discharge the sewage. The user can discharge the sewage relatively easily.

In this embodiment, the handle 40 has a left wall 44L and a right wall 44R (see FIG. 5). The left wall 44L and the right wall 44R prevent the finger hooked on the handle 40 from shifting to the left or right. Therefore, the work of lifting the handle 40 and tilting the container 20 forward becomes easy.

The horizontal wall 42 of the handle 40 may be tilted from the horizontal direction, and the vertical wall 43 may be tilted from the vertical direction. However, in the present embodiment, the horizontal wall 42 extends in the horizontal direction and the vertical wall 43 is tilted in the vertical direction. It extends (see FIG. 14). This facilitates the work of lifting the handle 40 and tilting the container 20 forward.

Dirt may adhere to the outside of the peripheral wall 26 of the container 20. In that case, when the handle 50 is rotated backward, the handle 50 may come into contact with the outside of the peripheral wall of the container 20, and the handle 50 may become dirty. However, according to the present embodiment, the handle 40 is configured so that the handle 50 can be placed when the handle 50 is tilted backward (see FIG. 21). When the handle 50 is tilted backward, the handle 50 is supported by the handle 40. This prevents the handle 50 from coming into contact with the outside of the peripheral wall of the container 20. Therefore, it is possible to prevent the handle 50 from becoming dirty.

According to the present embodiment, the length L20f in the front-rear direction between the front end 20f of the container 20 and the shaft hole 30 is larger than the length L20b in the front-rear direction between the rear end 20b of the container 20 and the shaft hole 30. long. This facilitates the work of holding the handle 40 and tilting the container 20 forward.

In the portable toilet 1, water is stored in the bucket 10 so as to reach a predetermined water level before use. As shown in FIG. 10, if the bottom wall 24 of the container 20 is inclined so as to move upward toward the front, it becomes easy to secure the water level in the container 20 even if the amount of water is relatively small. Therefore, water can be saved.

As shown in FIG. 15, the upper edge portion 22 of the container 20 has a liquid drain plate 23 projecting forward from the front portion of the outer peripheral wall 22C. Therefore, when the container 20 is tilted forward to discharge the sewage, the sewage flows down from the tip of the liquid drain plate 23. It is possible to prevent sewage from propagating through the outer peripheral wall 22C and the front peripheral wall 26B, and to prevent the outer peripheral wall 22C and the front peripheral wall 26B from becoming dirty. Therefore, it is possible to prevent the outer peripheral wall 22C and the front peripheral wall 26B of the container 20 from becoming dirty due to the discharge of sewage.

As shown in FIG. 3, the front peripheral wall 26B of the container 20 has a lower wall portion 27D, a left wall portion 27L, and a right wall portion 27R, which are the lower wall portion 27D, the left wall portion 27L, and the right wall portion. The portion 27R forms a flow path 27 extending back and forth when viewed from above. When the container 20 is tilted forward, the sewage in the container 20 is discharged through the flow path 27. According to the bucket 10, since the bucket 10 is provided with the flow path 27, sewage can be smoothly discharged. Further, the left and right width W27 of the flow path 27 is larger than half of the radius r24 of the bottom wall 24. The left and right widths W27 of the flow path 27 are relatively large. Therefore, the flow path 27 can guide a relatively large amount of sewage in a short time. Even when the container 20 is tilted relatively large in order to discharge the sewage quickly, the sewage does not spread laterally beyond the flow path 27, and the sewage can be prevented from splashing out of the toilet bowl 60. can. The sewage in the container 20 can be discharged in a relatively short time, and the work load on the user can be reduced.

<Other embodiments>
Although one embodiment of the present invention has been described above, the above-described embodiment is only an example. The present invention can be implemented in various other forms. Next, examples of other embodiments will be briefly described.

In the above embodiment, the stopper 56 is inserted into the shaft hole 30 with the handle 50 tilted backward (see FIG. 23), but as shown in FIG. 30, the handle 50 is tilted forward. The stopper 56 may be configured to be inserted into the shaft hole 30 in the state. That is, the stopper 56 may be formed so that the protrusion 56B is located inside the vertical hole 32 when the handle 50 is tilted forward when viewed from the axial direction. In this case, the handle 50 can be attached to the container 20 by tilting the handle 50 forward. When the handle 50 is tilted backward when the container 20 is attached to the toilet body 2 or placed on the floor or the like, the protrusion 56B of the stopper 56 is located below the circular hole 31, and the protrusion 56B is the circular hole 31. It can be engaged with the lower part. Therefore, it is possible to prevent the handle 50 from coming out of the container 20 not only when the handle 50 is lifted but also when the handle 50 is tilted backward.

As shown in FIG. 2, the spout is not formed in the upper edge portion 22 of the container 20 in the above embodiment, but as shown in FIG. 31, the front end portion of the upper edge portion 22 of the container 20 is recessed downward. The spout 29 may be formed. As a result, when the container 20 is tilted forward, the sewage is intensively discharged from the spout 29. Therefore, it is possible to prevent the sewage from scattering to the left and right, and the sewage can be satisfactorily discharged to the toilet bowl.

The shapes of the bottom wall 24 and the peripheral wall 26 of the container 20 described above are merely examples, and are not limited in any way.

The shape of the shaft hole 30 is not particularly limited as long as the shaft 54 of the handle 50 is rotatable. The configuration of the lock mechanism 55 that rotatably fixes the handle 50 to the container 20 when the handle 50 is lifted is not limited in any way.

The left wall 44L and the right wall 44R of the handle 40 may be omitted.

The handle 40 does not have to be configured so that the handle 50 can be placed when the handle 50 is tilted.

The length L20f in the front-rear direction between the front end 20f of the container 20 and the shaft hole 30 may be equal to the length L20b in the front-rear direction between the rear end 20b of the container 20 and the shaft hole 30. May be shorter than.

The liquid drain plate 23 of the container 20 may be omitted.

The left and right width W27 of the flow path 27 of the container 20 may be less than half of the radius r24 of the bottom wall 24. Further, the flow path 27 extending back and forth when viewed from above may not be provided.
