Description

Buckets for portable toilets and portable toilets

The present invention relates to a bucket for a portable toilet detachably mounted on a toilet body of a portable toilet and a portable toilet having the same.

The portable toilet is equipped with a detachable bucket disposed under a toilet seat. After use of the portable toilet, a user or a caregiver (hereafter collectively referred to as a user) removes the bucket from the bucket body and carries the bucket to a wastewater discharge location such as a toilet. Then, the user discharges the sewage accumulated in the bucket to a toilet bowl or the like of a toilet.

The bucket has a container and a handle placed over the top of the container. The user can remove the bucket by lifting the handle. In addition, the user can move the bucket by moving while gripping the handle. When removing and carrying the bucket, the handle is gripped in an upright state, but when using a portable toilet, the handle is in a collapsed state so as not to interfere. Therefore, the handle is assembled so as to be able to rotate with respect to the container.

However, if the handle is rotatable, when the user moves the bucket by gripping the handle, the container may be shaken and the sewage may be scattered outside. In addition, when the container touches furniture or the like while being moved, there is a possibility that the container tilts and overflows with sewage.

Then, the present inventor conceived of providing a mechanism (hereinafter referred to as a lock mechanism) fixed to the bucket for a portable toilet so as not to rotate with respect to the container when the handle is lifted. For example, Patent Literature 1 discloses a bucket provided with such a locking mechanism, although not for a portable toilet.

As shown in FIG. 32(a), the locking mechanism disclosed in Patent Literature 1 is constituted by a shaft hole 501 formed in a container 500 and a shaft 511 provided in a handle 510. there is. Shaft hole 501 is formed in a branch shape, and consists of a circular hole 502 and a vertical hole 503 above the circular hole 502 . The shaft 511 of the knob 510 has a rectangular cross section. As shown in Fig. 32(a), in a state where the knob 510 is knocked down, since the shaft 511 is located inside the circular hole 502, the knob 510 can rotate. On the other hand, as shown in Fig. 32(b), when the knob 510 is lifted upright, the shaft 511 moves from the round hole 502 to the vertical hole 503, so it becomes impossible to rotate. As a result, the handle 510 is fixed to the container 500 without rotation.

Japanese Utility Model Publication No. 54-148540

When a user discharges sewage from a bucket to a toilet bowl of a toilet bowl, first, as shown in Fig. 33(a), the container 500 is positioned above the toilet seat 520 while gripping the handle 510. At this time, as shown in Fig. 33(b), the shaft 511 of the knob 510 is caught in the longitudinal hole 503, and rotation of the knob 510 is restricted. Next, the user tilts the container 500 while holding the handle 510, as shown in Fig. 34(a). In the bucket provided with the locking mechanism, since the handle 510 is fixed to the container 500 immovably, the user tilts the handle 510 together with the container 500. At this time, a tilting force from the vertical hole 503 acts on the shaft 511 of the knob 510 (see Fig. 34(b)). The shaft 511 slides from the longitudinal hole 503 toward the circular hole 502 while gradually inclining. Then, when the degree of inclination increases, the shaft 511 moves away from the longitudinal hole 503 (see Fig. 35(b)). When the shaft 511 deviates from the vertical hole 503, the fixation of the handle 510 is released, and the container 500 tilts sharply (see Fig. 35(a)). As a result, a problem arises in that sewage is discharged with strong force toward the toilet 520 and the sewage is scattered outside the toilet 520 .

An object of the present invention is to keep the upper and lower dimensions of the shaft hole of the container small, fix the handle so that it does not rotate with respect to the container, and to prevent the handle from being unfixed when discharging sewage by tilting the container while holding the handle. It is to provide a portable toilet bucket and a portable toilet equipped with the bucket.

A bucket for a portable toilet according to the present invention comprises a container having an upper edge portion opened upwards, a left portion and a right portion, and a container placed from the left portion to the right portion of the container and rotatably engaged with the container. Provide a handle. At least one of the left and right sides of the container is formed with a shaft hole including a circular hole and a longitudinal hole extending upward in a straight line from the circular hole. The handle has a shaft inserted into the shaft hole. The shaft is rotatable within the circular hole, and is configured to move from the circular hole to the final hole and be caught in the final hole when the handle is raised and lifted. The vertical hole has a front edge extending linearly upward from the front end of the circular hole, and a rear edge formed behind the front edge and extending upward linearly. The shaft has a first shaft edge on a straight line opposite to the front edge and a second shaft edge on a straight line opposite to the rear edge when the shaft is inserted into the longitudinal hole. A vertical length of the front edge is longer than a length of the first shaft edge.

According to the bucket for the portable toilet, since the shaft of the handle is rotatable inside the circular hole of the container, the handle is rotatable with respect to the container. Since the handle can be knocked down when the bucket is attached to the toilet body of the portable toilet, the handle does not get in the way when using the portable toilet. On the other hand, when the handle is lifted upright, the shaft of the handle moves from the round hole to the end hole of the container and is caught in the end hole. Thereby, the handle is secured against rotation relative to the container. Therefore, it becomes easy to move the bucket so that sewage does not overflow. When discharging sewage from a bucket, tilt the container forward while holding the handle. At this time, a force inclined from the vertical hole acts on the shaft. However, in the bucket, the upper and lower length of the front edge of the vertical hole is longer than the length of the first shaft edge of the shaft. Therefore, even if the force acts on the shaft, the lower end of the first shaft edge remains supported by the front edge of the vertical hole, and the shaft does not deviate from the vertical hole. Therefore, the fixation of the handle is not released, and the container can be prevented from tilting rapidly. Therefore, it is possible to prevent waste water from being discharged from the container with strong force. Further, according to the portable toilet bucket, the front edge of the longitudinal hole extends upward from the front end of the circular hole. Therefore, it is possible to suppress the vertical dimension of the shaft hole while securing the vertical length of the front edge.

The vertical length of the rear edge may be shorter than the length of the first shaft edge.

In this way, the vertical dimension of the shaft hole can be further suppressed.

The vertical length of the front edge of the vertical hole may be longer than the hole width between the front edge and the rear edge of the vertical hole.

If the vertical length of the front edge of the vertical hole is increased in this way, the shaft becomes more difficult to deviate from the vertical hole. It is possible to more reliably prevent the handle from being unfixed when the container is tilted.

The cross-sectional shape of the shaft is the first shaft edge, the second shaft edge, a third shaft edge connecting one end of the first shaft edge and one end of the second shaft edge, and the other end of the first shaft edge It may be formed in a quadrangular shape having a fourth shaft edge connecting the other end of the second shaft edge. Lengths of the first shaft edge and the second shaft edge may be longer than the lengths of the third shaft edge and the fourth shaft edge.

Accordingly, since the length of the first axial edge is relatively long, the contact area between the first axial line and the front edge is relatively large. The shaft of the handle is sufficiently supported by the front edge of the vertical hole. Therefore, it is possible to more reliably prevent the shaft from moving away from the longitudinal hole. It is possible to more reliably prevent the fixation of the handle from being released.

The handle may have a stopper formed on the distal end side of the shaft. The stopper may have a stopper main body portion at least part of which is located inside the circular hole when viewed from the axial direction of the shaft when the handle is knocked down, and a protruding portion projecting upward from the stopper main body portion. The protrusion is formed so as to overlap the periphery of the vertical hole of the container when viewed from the axial direction of the shaft when the handle is knocked down and located inside the vertical hole when viewed from the axial direction of the shaft, and when the handle is lifted upright. it may be

Accordingly, the knob has a stopper formed on the distal end side of the shaft, but in a state where the knob is knocked down, the protruding portion of the stopper is located inside the longitudinal hole when viewed from the axial direction of the shaft. Therefore, it is easy to pass the stopper through the shaft hole, and the handle can be easily attached to the container. When the handle is lifted upright, the protruding portion of the stopper overlaps the peripheral portion of the longitudinal hole of the container when viewed in the axial direction of the shaft. Therefore, even if the handle is displaced in the axial direction of the shaft, the protruding portion of the stopper is in contact with the periphery of the vertical hole, so the shaft does not come off from the vertical hole and the handle is prevented from being removed from the container. Accordingly, it is possible to provide a bucket for a portable toilet whose handle does not easily fall out of the container.

The stopper body portion may be formed in a circular shape having an outer diameter larger than the hole width of the vertical hole when viewed in an axial direction of the shaft. The cross-sectional shape of the shaft may be formed in a rectangular shape.

The shaft hole may be formed in a left side portion and a right side portion of the container. The shaft and the stopper may be formed on both sides of the handle.

Even if the protrusion is formed so as to be located inside the vertical hole when viewed from the axial direction of the shaft when the handle is lowered backward, and positioned forward of the vertical hole when viewed from the axial direction of the shaft when the handle is lifted upright. do.

Accordingly, in a state in which the handle is tilted backward, since the protruding portion of the stopper is located inside the vertical hole, the stopper can pass through the shaft hole. By knocking the handle backwards, the handle can be attached to the container. When the handle is erected and lifted, the protruding portion of the stopper is located in front of the longitudinal hole, so that the protruding portion can be engaged with the front portion of the longitudinal hole of the container. Therefore, the handle is prevented from coming off the container.

The container may have an inverted U-shaped reinforcing rib protruding from a peripheral portion of the vertical hole in one direction of an axial line of the shaft. The knob may have a reinforcing portion formed on one side of the axial direction of the shaft with respect to the first shaft edge and the second shaft edge, and inserted inside the reinforcing rib when the knob is lifted upright.

Accordingly, when the container is tilted, the force applied to the container from the shaft is supported not only by the front edge of the longitudinal hole but also by the reinforcing rib. Since the peripheral portion of the vertical hole is not easily deformed, the shaft is further prevented from deviating from the vertical hole. Therefore, when the container is tilted, it is possible to more effectively prevent the handle from being unfixed.

The container may have transverse ribs extending forward or backward from the reinforcing ribs.

Accordingly, the periphery of the longitudinal hole becomes more difficult to deform, and the deviation of the shaft from the longitudinal hole is prevented more reliably. When the container is tilted, the fixation of the handle can be more effectively prevented from being released.

The front-back length of the container may be longer than the left-right length of the container.

A length in the front-back direction between the front end of the container and the shaft hole may be longer than a length in the front-back direction between the rear end of the container and the shaft hole.

The bottom wall of the container may be inclined upward toward the front.

In a portable toilet, water is collected in a bucket before use to reach a predetermined water level. According to the above, it becomes easy to secure the water level in the container when the water quantity is relatively small. Therefore, water can be saved.

The upper edge portion of the container may have an outer circumferential wall extending vertically and a liquid-cutting plate protruding forward from a front portion of the outer circumferential wall.

Accordingly, when the container is tilted to discharge the sewage, the sewage flows down from the tip of the liquid plate. The movement of sewage along the outer circumferential wall is suppressed, and contamination of the outer circumferential wall is suppressed. Therefore, contamination of the outer circumferential wall of the container due to discharge of filthy water can be suppressed.

An inlet concave downward may be formed at the front end of the upper edge portion of the container.

Accordingly, when the container is tilted, the sewage is intensively discharged from the inlet. Therefore, it is prevented that the sewage water is scattered from side to side. Sewage can be discharged satisfactorily into a toilet bowl or the like.

A portable toilet related to the present invention is provided with the aforementioned portable toilet bucket.

According to the present invention, while keeping the vertical dimension of the shaft hole of the container small, the handle can be fixed so as not to rotate with respect to the container, and the fixation of the handle is not released when the container is tilted while holding the handle to discharge sewage. A toilet bucket and a portable toilet equipped with the bucket can be provided.

In addition, the toilet main body 2 shown in FIG. 1 is only an example. As long as the bucket 10 is detachably mounted, the configuration of the toilet body 2 is not particularly limited. The armrest 7, the backrest 6, or the cover 8 is not necessarily required. When the chair part 3 is formed so that it may be directly mounted on the floor, the leg 4 may be absent.

<bucket>

Next, the bucket 10 will be described. In the description of the bucket 10 below, when the bucket 10 is attached to the toilet body 2, the user sitting on the toilet seat 5 sees the front, rear, left, right, It is assumed that each direction of the right is respectively meant. Up and down mean up and down when the bucket 10 is placed on a horizontal surface, respectively. Symbols F, Re, L, R, U, and D in the figure indicate front, back, left, right, top, and bottom, respectively.

Unless otherwise specified, the front shall include not only the forward direction in the horizontal direction, but also the direction tilted at an angle of less than 90 degrees left and right from the direction. The backward direction shall include not only the backward direction in the horizontal direction, but also the direction inclined at an angle of less than 90 degrees left and right from the direction. The term "left" includes not only the leftward direction in the horizontal direction but also a direction inclined at an angle of less than 90 degrees forward and backward from the direction. The term "right" includes not only the rightward direction in the horizontal direction, but also a direction inclined at an angle of less than 90 degrees forward and backward from the direction.

The handle 50 is placed from the left side of the container 20 to the right side. The handle 50 is placed across the container 20 so as to span the upper edge portion 22 . Although detailed later, the handle 50 is engaged with the container 20 around the axis C1 so that rotation is possible.

<Courage>

3, 4, 5, and 6 are a plan view, a left view, a rear view, and a bottom view of the container 20, respectively. Fig. 7 is a longitudinal cross-sectional view of the container 20, and is a cross-sectional view along line VII-VII of Fig. 5; 8 is a horizontal sectional view of the container 20, and is a sectional view along line VIII-VIII of FIG. As shown in FIG. 7 , the container 20 includes a bottom wall 24, a circumferential wall 26 extending upward from the bottom wall 24, and an upper edge portion located above the circumferential wall 26. (22) and an annular leg (28) formed below the bottom wall (24).

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 downward concave shape. In the present embodiment, the bottom wall 24 includes a circular horizontal wall 24A extending horizontally and viewed from above, and an inclined wall 24B inclined upward from the outer circumferential end of the horizontal wall 24A. Have.

However, the shape of the bottom wall 24 is not particularly limited. As shown in FIG. 9, the bottom wall 24 may be curved concavely. The bottom wall 24 may be formed without 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 upward toward the front. Also in this case, the bottom wall 24 may be formed in a circular shape when viewed from above.

As shown in FIG. 8 , the circumferential wall 26 includes a rear circumferential wall 26A having an arc-shaped horizontal cross section and a front circumferential wall extending forward from the rear circumferential wall 26A and having a forward convex horizontal cross section ( 26B). As shown in Fig. 4, when viewed from the side, the outline of the front circumferential wall 26B has a curved portion 26BL such that the inclination angle α with respect to the horizontal line decreases as it goes upward. The ratio of the curved portion 26BL to the entire outline of the front circumferential 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 outline of the front circumferential wall 26B may be the curved portion 26BL.

As shown in Fig. 7, an upper vertical wall 26BU is formed above the curved portion 26BL so that the inclination angle α with respect to the horizontal line decreases as it goes upward. The upper vertical wall 26BU is a substantially vertical wall. The upper vertical wall 26BU may extend vertically or may be slightly inclined from the vertical plane. For example, the upper vertical wall 26BU may be inclined at an angle within ±10 degrees from the vertical plane, preferably within ±5 degrees. The upper vertical wall 26BU serves to prevent urine from scattering forward of the container 20 with the force of urination when the portable toilet 1 is used. From the viewpoint of preventing urine from scattering, the upper and lower dimensions of the upper vertical wall 26BU are preferably 3 mm or more, more preferably 8 mm or more. On the other hand, if the top and bottom dimensions of the upper vertical wall 26BU are 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. As a result, it tends to come into contact with the upper vertical wall 26BU and come out easily. From the viewpoint of preventing the scattering of such sewage, the vertical dimension of the upper vertical wall 26BU is preferably 30 mm or less, more preferably 20 mm or less. When the upper and lower dimensions of the upper and lower vertical walls 26BU are 17 mm or less, splashing of sewage can be further prevented.

Fig. 11 is a vertical sectional view of the front circumferential wall 26B, and is a sectional view along line XI-XI in Fig. 4 . The vertical section shown in FIG. 11 is a vertical section of the front side wall 26B at an intermediate position between the rear end 26Bb of the front side wall 26B and the front end 20f of the container 20. As shown in Fig. 11, the front circumferential wall 26B has a lower wall portion 27D, a left wall portion 27L extending upward from the left end of the lower wall portion 27D, and an upper portion from the right end of the lower wall portion 27D. It has a right wall portion 27R extending to . As shown in Fig. 3, the flow passage 27 extending forward and backward when viewed from above is formed by the lower wall portion 27D, the left wall portion 27L, and the right wall portion 27R.

The left and right widths W27 of the flow path 27 are relatively large. In addition, the left and right width W27 of the flow path 27 here means the cross section of the flow path 27 (between the rear end 26Bb of the front circumferential wall 26B and the front end 20f of the container 20 at an intermediate position). It refers to the width of the left and right sides of a section). The left and right width W27 of the passage 27 is greater than half the radius r24 of the bottom wall 24 . In addition, 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 passage 27 is larger than the radius r24 of the bottom wall 24 . Further, the left and right widths W27 of the passage 27 are larger than the radius r28 of the annular leg 28 (see Fig. 6). In addition, the radius of the annular leg 28 shall mean 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. In the substantially annular shape, a shape that goes around the center 24C of the bottom wall 24 (that is, a strict annular shape) and a shape in which an incision 28a is formed in a part of the annular shape as shown in FIG. 6 . This is included.

The upper limit of the left and right width W27 of the flow path 27 is not particularly limited, but is preferably 170 mm or less, for example. This makes it easy to inject sewage at once without overflowing even with a relatively small water flow part of a standard Japanese toilet.

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 , a step 25 is formed on the circumferential wall 26 as a guide indicating the position of the water surface when a predetermined volume of water is stored in the container 20 . Here, the level difference 25 is formed at the position of the water surface when water of a volume of 1 liter is stored in the container 20. Since a sufficient water level can be ensured by storing 1 liter of water, the feces are usually submerged in water and the generation of odor can be suppressed. The step 25 is formed on the rear circumferential wall 26A, but may be formed on the front circumferential wall 26B. In addition, an eye mark should just be what can be visually recognized, and is not limited to the level difference 25. As an eye mark, you may use grooves, protrusions, etc. instead of the step 25. Moreover, you may use colored lines, figures, characters, symbols, etc. as an eye mark. However, using the level difference 25 as an eye mark is particularly preferable because visibility can be ensured even if dirt is deposited, and it does not disappear even after long-term use.

As shown in FIG. 7 , the upper edge portion 22 includes an inner circumferential wall 22A located above the circumferential wall 26, an upper wall 22B extending outward from the upper end of the inner circumferential wall 22A, It has an outer peripheral wall 22C extending downward from the outer end of the upper wall 22B. The upper edge portion 22 is formed in a shape bent downward from the inner side toward the outer side. The upper edge portion 22 is formed in an inverted U-shape in cross section. In addition, the inner circumferential wall 22A may coincide with the upper vertical wall 26BU described above, or may be a part of the upper vertical wall 26BU.

As shown in FIG. 4 , shaft holes 30 into which handles 50 (see FIG. 2 ) are engaged are formed in the left and right portions of the container 20 . Here, the shaft hole 30 is formed on the left side and right side of the outer circumferential wall 22C of the upper edge portion 22 .

As shown in FIG. 12 , the shaft hole 30 includes a circular hole 31 and a vertical hole 32 extending upward from the circular hole 31 . In addition, the virtual line 30S in FIG. 12 is a line which shows the boundary of the circular hole 31 and the vertical hole 32. As shown in FIG.

The center line of the vertical hole 32 (a line extending vertically passing through the middle of the front edge 32f and the rear edge 32b) 32CL extends from the center 31C of the round hole 31 to the front edge 32f side. is out of sync The vertical length H32f of the front edge 32f is longer than the hole width W32 between the front edge 32f and the rear edge 32b.

As shown in Fig. 13, an inverted U-shaped reinforcing rib 34 projecting outward is formed around the vertical hole 32 of the outer peripheral wall 22C. The reinforcing rib 34 protrudes in one direction in the axial direction from the outer peripheral wall 22C. In detail, a reinforcing rib 34 protruding left is formed around the vertical hole 32 on the left side, and a reinforcing rib 34 protruding rightward is formed around the peripheral hole 32 on the right side. has been The reinforcing ribs 34 include a front rib 34A located in front of the vertical hole 32, a rear rib 34B located in the rear of the vertical hole 32, and an upper rib located above the vertical hole 32. (34T). In addition, circular arc-shaped reinforcing ribs 35 protruding outward are also formed around the circular hole 31 . The reinforcing rib 34 and the reinforcing rib 35 are connected. In this embodiment, the reinforcing rib 34 and the reinforcing rib 35 are formed so as to surround the entire shaft hole 30 .

Further, transverse ribs 36A and 36B extending forward and backward from the reinforcing rib 34 are formed on the outer peripheral wall 22C. The transverse rib 36A is formed above the transverse rib 36B. The front-rear length of the lower transverse rib 36B is longer than the front-rear length of the upper transverse rib 36A.

As shown in FIGS. 4 and 5 , a handle 40 protruding rearward is formed on the rear side of the upper edge portion 22 and at the center portion in the left-right direction. Fig. 14 is a longitudinal sectional view of the handle 40, and is an enlarged view of part XIV in Fig. 7 . As shown in FIG. 14, the handle 40 includes a curved wall 41 extending rearwardly and downwardly from the lower end of the outer circumferential wall 22C, and a side wall 42 extending rearward from the rear end of the curved wall 41. and a vertical wall 43 extending downward from the rear end of the transverse wall 42 .

As shown in Fig. 15, the upper edge portion 22 of the container 20 is provided with a liquid-clamping plate 23 protruding forward from the front of the outer circumferential wall 22C. Here, the liquid-removing plate 23 is formed flush with the upper wall 22B.

As shown in FIG. 2 , the front-back length of the container 20 is longer than the left-right length of the container 20 . As shown in FIG. 4 , the length L20f in the front-back direction between the front end 20f of the container 20 and the shaft hole 30 is the length L20f in the front-back direction between the rear end 20b of the container 20 and the shaft hole 30 is longer than the length of (L20b). In addition, the length in the front-back direction between the front end 20f of the container 20 and the shaft hole 30 is the center position in the front-back direction of the front end 20f of the container 20 and the shaft hole 30 (here, the round hole 31 ) refers to the length in the front-back direction between the positions of the center 31C) of ). Similarly, the length in the front-back direction between the rear end 20b of the container 20 and the shaft hole 30 is the center position in the front-back direction of the rear end 20b of the container 20 and the shaft hole 30 (here, the circular hole ( 31) refers to the length in the front-back direction between the positions of the centers 31C).

The above is the configuration of the container. Next, the handle 50 will be described. 16 is a perspective view of the handle 50. Fig. 17 is an enlarged view of part XVII of Fig. 16;

<handle>

As shown in FIG. 16 , the handle 50 has a bottled portion 51 and engaging portions 52 formed at both ends of the bottled portion 51 . The engaging portion 52 is a portion engaged with the shaft hole 30 of the container 20 . As shown in FIG. 17 , the engaging portion 52 extends inward from the front end of the bottle portion 51 . The engaging portion 52 has a shaft 54, a stopper 56 formed inside the shaft 54, and a reinforcing portion 58 formed outside the shaft 54. The stopper 56 is formed on the tip side of the shaft 54. In detail, the engaging part 52 on the right side of the handle 50 is a reinforcing part 58, a shaft 54 formed on the left side of the reinforcing part 58, and a stopper formed on the left side of the shaft 54 (56). The engaging portion 52 on the left side of the handle 50 includes a reinforcing portion 58, a shaft 54 formed on the right side of the reinforcing portion 58, and a stopper 56 formed on the right side of the shaft 54. Have.

Shaft 54 is formed in the shape of a square prism. As shown in Fig. 18, the cross-sectional shape of the shaft 54 is formed in a rectangular shape. Note that the quadrangular shape referred to herein is not limited to a strict quadrangle with right angle corners, but also includes a quadrangular shape with rounded corners as shown in FIG. 18 . The shaft 54 includes 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 a second shaft edge. It has a third shaft edge 54c connecting one end of 54b and a fourth shaft edge 54d connecting the other end of the first shaft edge 54a and the other end of the second shaft edge 54b. The lengths of the first shaft edge 54a and the second shaft edge 54b are longer than the lengths of the third shaft edge 54c and the fourth shaft edge 54d.

Since the handle 50 is engaged with the container 20 so that rotation is possible, as shown in FIG. 19 , the handle 50 can be knocked down forward. Moreover, as shown in FIG. 20, the knob 50 can stand upright. Moreover, as shown in FIG. 21, the knob 50 can be knocked back. Also, when the handle 50 is tipped backward, the handle 50 rests on the side wall 42 of the handle 40. When the handle 50 is knocked back, the handle 50 is supported by the handle 40 .

Shaft 54 is inserted into shaft hole 30 . The shaft 54 is formed in a size capable of rotating within the circular hole 31 . The maximum dimension L54 of the cross section of the shaft 54 (here, the dimension in the diagonal direction. See Fig. 18) is smaller than the inner diameter of the circular hole 31. When the shaft 54 is within the circular hole 31, the handle 50 can be rotated. When the handle 50 is in a collapsed state, the shaft 54 is disposed in the circular hole 31.

When the handle 50 is lifted upright (see Fig. 20), as shown in Fig. 22, the shaft 54 moves from the circular hole 31 to the vertical hole 32 and is caught in the vertical hole 32. When the shaft 54 is caught in the vertical hole 32, rotation of the shaft 54 is restricted by the vertical hole 32. Therefore, when the handle 50 is erected and lifted, the handle 50 becomes unable to rotate. The shaft 54 and the vertical hole 32 constitute a locking mechanism 55 that fixes the handle 50 to the container 20 in a non-rotatable manner when the handle 50 is lifted upright.

When the shaft 54 is caught in the longitudinal hole 32, the first shaft edge 54a opposes the front edge 32f of the longitudinal hole 32, and the second shaft edge 54b faces the rear edge of the longitudinal hole 32. It opposes (32b). The third shaft edge 54c abuts against 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 front 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 rear edge 32b of the longitudinal hole 32 is shorter than the length H54a of the first shaft edge 54a.

As shown in FIG. 18, the reinforcement part 58 is formed in the shape of a square column like the shaft 54. The cross-sectional shape of the reinforcing portion 58 is formed in a rectangular shape one size larger than the shaft 54 . As shown in FIG. 22 , when the shaft 54 is caught in the vertical hole 32, the reinforcing portion 58 is inserted inside the reinforcing rib 34. The reinforcing portion 58 is sandwiched inside the reinforcing rib 34 and contacts the reinforcing rib 34 .

As shown in Fig. 17, the stopper 56 has a disk-shaped stopper body portion 56A and a protruding portion 56B protruding from the stopper body portion 56A. When viewed in the axial direction of the shaft 54, the stopper 56 is formed in a b-shape. The stopper 56 is formed to prevent the engaging portion 52 of the knob 50 from being pulled out of the shaft hole 30. 23 to 25 are views schematically illustrating 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, views of the outer peripheral wall 22C on the right side of the container 20 viewed from the left side to the right) ) am.

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

As shown in Fig. 21, when the handle 50 is knocked down backward, as shown in Fig. 23, when viewed in the axial direction, the projecting portion 56B protrudes upward from the stopper main body 56A. When viewed from the axial direction when the knob 50 is tilted backward, the protrusion 56B is located inside the longitudinal hole 32 . The container 20 is made of resin and has elasticity. When the stopper 56 is inserted into the shaft hole 30 in a state in which the handle 50 is tilted backward, the round hole 31 is temporarily pressed by the stopper main body 56A and spreads. Accordingly, the stopper body portion 56A can pass through the circular hole 31 . Moreover, since the protruding part 56 is located inside the vertical hole 32, it 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 in a state in which the knob 50 is tilted backward, the stopper 56 is moved to the rear side of the shaft hole 30 (in other words, the outer circumferential wall ( 22C)).

As shown in Fig. 24, when the handle 50 is rotated in a fallen state, the protruding portion 56B moves outside the shaft hole 30 when viewed in the axial direction. The protruding portion 56B overlaps the peripheral portion of the shaft hole 30 of the outer circumferential wall 22C when viewed in the axial direction. When the protruding portion 56B comes into contact with the periphery of the shaft hole 30, displacement of the handle 50 in the axial direction is restricted, and the handle 50 is prevented from coming out of the shaft hole 30.

As shown in FIG. 20 , when the handle 50 is lifted upright, the shaft 54 moves from the round hole 31 to the vertical hole 32 as shown in FIG. 25 . The projecting portion 56B is located in front of the vertical hole 32 when viewed in the axial direction. Also in this case, the protruding portion 56B overlaps the peripheral portion of the shaft hole 30 of the outer circumferential wall 22C when viewed in 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 detaches the bucket 10 from the toilet body 2 by standing up and lifting the handle 50. Moreover, the user carries the bucket 10 to the toilet by moving while gripping 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 circumferential wall 26B inclines in an upward direction when viewed from the side. The container 20 is formed so that, when a predetermined amount or less of water is stored, the center of gravity of the container 20 and the entire water in the front-back direction is located near the shaft hole 30 regardless of the water level. . That is, the container 20 is formed so that the center of gravity of the sum of the container 20 and the water is located directly below the shaft hole 30 when water of a predetermined volume or less is stored, and even if the water level changes, the center of gravity of the center of gravity It is formed so that the fluctuation of a position may be small.

Since it becomes difficult to move the bucket 10 when the storage amount of the container 20 is too large, in the portable toilet 1, the upper limit of the storage volume of the container 20 is set in advance in many cases. The said predetermined volume may be the same as the upper limit of the storage volume of the container 20, for example. However, it is not limited. The said predetermined volume should be less than the upper limit of the storage volume of the container 20. Here, as shown in FIG. 20 , in the container 20, when 50% or less of the internal volume of the container 20 is stored, the position of the center of gravity of the container 20 and the entire water in the front-back direction is Regardless of the water level, it is formed to be positioned 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 fluctuation of the front-back position of the center of gravity is reduced even when the water level changes, but when the bucket 10 is removed from the toilet body 2 or carried, the bucket 10 ) may be shaken or tilted by contact with furniture, etc. Depending on the shape of the container 20, there may be cases where the center of gravity moves to the tilted side and gravity acts to promote the tilt. In that case, the inclination becomes large, and a phenomenon in which sewage overflows from the container 20 may occur. For example, there is a case where a reservoir corner shape in which water can accumulate on an inclined side exists at a point away from a vertical plane passing through the axis C1 (see Fig. 2) of the shaft hole 30, or the like. However, this phenomenon can be avoided by devising the shape of the container 20 to reduce the volume of water accumulated on the inclined side. For example, the above phenomenon can be avoided by giving an angle to the floor so that the angle formed between the bottom serving as the corner of the reservoir and the front and rear walls is small, by making the bottom and the front and rear walls a curved or spherical surface, or by making the bottom deep. can

In this embodiment, the container 20 is formed as follows. 26(a) to (c), a vertical line VP represents a vertical plane passing through the axis line C1 of the shaft hole 30. The angle θ represents the angle of inclination of the container 20 with respect to the horizontal plane. 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, the container 20 is at least 0 degrees from the horizontal surface, as shown in FIG. When inclined backward and downward at an angle θ of greater than 20 degrees, the center of gravity G is formed to be located forward of the vertical plane VP. In addition, as shown in FIG. 26(c), when the container 20 stores water of 50% or less of the internal volume of the container 20, the container 20 is at least larger than 0 degrees with respect to the horizontal plane, and When tilted forward and downward at an angle θ of less than 20 degrees, the center of gravity G is formed to be located rearward than the vertical plane VP.

According to the present embodiment, when the bucket 10 is detached from the toilet body 2 or carried, at least when the container 20 is tilted at an angle of less than 20 degrees, gravity reverses the tilt. it works to Therefore, the inclination is prevented from increasing, and overflow of waste water from the container 20 is suppressed. Further, even when the container 20 is inclined at an angle of 20 degrees or more, it may be configured so that gravity acts so as to reverse the inclination.

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 a user uses the portable toilet 1, sewage is collected in the bucket 10. In order to dispose of the dirty water in the bucket 10, the user first lifts up the handle 50 to remove the bucket 10 from the toilet body 2. At this time, the shaft 54 of the handle 50 is caught in the longitudinal hole 32 of the container 20, and the handle 50 is immovably fixed to the container 20. Therefore, the user can remove the bucket 10 easily.

Next, the user moves to the toilet while holding the handle 50 . At this time, since the handle 50 is immovably fixed to the container 20, shaking of the container 20 is suppressed. Moreover, even if the container 20 touches furniture etc. in the middle of carrying, it does not incline greatly. Therefore, when the bucket 10 is being moved, overflowing of sewage water can be prevented.

After arriving at the toilet, the user discharges the sewage from the bucket 10 into the toilet bowl of the toilet. Referring to Figs. 27 to 29, the operation of discharging sewage from the bucket 10 to the toilet bowl will be described. 27(a), 28(a), and 29(a) are side views schematically illustrating a bucket and a toilet, and FIGS. 27(b), 28(b), and 29(b) show shaft and a diagram schematically showing the shaft hole.

As shown in FIG. 27(a), the user holds the handle 50 with one hand h1 above the toilet bowl 60, while the other hand h2 holds the handle 50 of the container 20 ( 40) from below. 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 into the toilet bowl. At this time, as shown in FIG. 28(b), the shaft 54 of the handle 50 is pressed from the peripheral portion of the vertical hole 32, and the shaft 54 is subjected to a force tilting from the vertical hole 32 (see arrow A1 ) works. However, since the vertical length of the front 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 first shaft edge 54a The lower end portion 54ad of the vertical hole 32 remains supported by the front edge 32f. Therefore, the shaft 54 is prevented from coming out of the vertical hole 32.

Therefore, as shown in FIGS. 29(a) and (b), even if the container 20 is greatly tilted, the shaft 54 does not come out of the vertical hole 32 and the fixation of the handle 50 is not released. With the handle 50 maintained in a fixed state, the container 20 can be tilted according to the user's intention. If the fixing of the handle 50 is unintentionally released while the container 20 is tilted, the container 20 tilts at once, and there is a risk that sewage water is rapidly discharged and scattered outside the toilet bowl 60. However, according to this embodiment, such a thing can be prevented.

After discharging 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 a floor surface of a bathtub and the like, and the handle 50 is knocked backwards. In this way, the inside of the container 20 can be cleaned without being obstructed by the handle 50.

After washing the bucket 10, the user collects a predetermined volume of water in the container 20. Then, the handle 50 is lifted upright, the bucket 10 is moved while gripping the handle 50, and attached to the toilet body 2. After that, the handle 50 is knocked down backwards, and the toilet seat 5 (see Fig. 1) is knocked forward. With this, the portable toilet 1 becomes usable again. The operation of collecting water in the container 20 is not limited to before attaching the bucket 10 to the toilet body 2, but may be performed after attaching the bucket 10 to the toilet main body 2.

The above is an example of how to use the bucket 10. In addition, although it was assumed here that the sewage from the bucket 10 is discharged to the toilet bowl 60 of the lavatory, the discharge location of the filthy water is not limited to the toilet bowl of the lavatory.

<Effect of Embodiment>

Next, various effects brought about by the present embodiment will be described.

As described above, according to the bucket 10 according to the present embodiment, the shaft 54 of the handle 50 is rotatable inside the hole 31 of the container 20, so the handle 50 is a container ( 20) can be rotated about. When the bucket 10 is attached to the toilet body 2 of the portable toilet 1, the handle 50 can be knocked down backwards (see FIG. 1), so when using the portable toilet 1, the handle 50 ) is not in the way. On the other hand, when the handle 50 is lifted upright, the shaft 54 of the handle 50 moves from the round hole 31 of the container 20 to the vertical hole 32 and is caught in the vertical hole 32. Thereby, the handle 50 is fixed non-rotatably relative to the container 20 . Therefore, it becomes easy for the user to move the bucket 10 so that the sewage does not overflow.

When draining sewage from the bucket 10, the container 20 is tilted while holding the handle 50. According to the bucket 10 according to the present embodiment, the vertical length H32f of the front edge 32f of the vertical hole 32 is longer than the length H54a of the first shaft edge 54a of the shaft 54. Therefore, while the container 20 is tilted, the lower end of the first shaft edge 54a remains supported by the front edge 32f, and the shaft 54 does not come out of the longitudinal hole 32 (FIG. 28(b) ) and see FIG. 29(b)). Accordingly, it is possible to prevent the container 20 from tilting abruptly while the container 20 is tilted without being released from the fixation of the handle 50 . Accordingly, it is possible to prevent waste water from being discharged from the container 20 with strong force. It can prevent sewage water from scattering outside the toilet bowl 60.

In this embodiment, as shown in FIG. 12, when viewed from the axial direction of the shaft 54, the shaft hole 30 is formed in a b-shape. The center line 32CL of the vertical hole 32 is shifted from the center 31C of the circular hole 31 toward the front edge 32f side. When the vertical hole 32 is formed so that the center line 32CL passes through the center 31C of the circular hole 31, and the vertical length H32f of the front edge 32f is to be equally secured, the shaft hole 30 It is necessary to lengthen the top and bottom length. When the center line 32CL passes through the center 31C of the circular hole 31, the vertical length of the shaft hole 30 is the vertical length H31 of the circular hole 31 and the vertical length H32f of the front edge 32f. is the length of However, according to the present embodiment, the vertical length of the shaft hole 30 is shorter than the sum of the vertical length H31 of the circular hole 31 and the vertical length H32f of the front edge 32f. Accordingly, the vertical length of the front edge 32f can be secured while the overall vertical dimension of the shaft hole 30 is suppressed. According to this embodiment, the shaft hole 30 exhibiting the above-mentioned effect can be miniaturized.

In this embodiment, the vertical length H32b of the rear edge 32b of the vertical hole 32 is shorter than the length H54a of the first shaft edge 54a. Accordingly, the upper and lower dimensions of the shaft hole 30 can be further suppressed.

Although not particularly limited, in the present embodiment, the vertical length H32f of the front edge 32f is longer than the hole width W32 between the front edge 32f and the rear end 32b of the vertical hole 32. The shaft 54 is configured to be more difficult to come off from the vertical hole 32 . Therefore, when the container 20 is tilted, it is possible to prevent the fixation of the handle 50 from being released more reliably.

According to this embodiment, the cross-sectional shape of the shaft 54 is formed in a rectangular shape, and the lengths of the first shaft edge 54a and the second shaft edge 54b are the third shaft edge 54c and the fourth shaft edge 54c. It is longer than the length of the edge 54d. Since the length of the first shaft edge 54a is relatively long, the contact area between the first shaft edge 54a and the front edge 32f is relatively large. The shaft 54 is sufficiently supported by the front edge 32f of the vertical hole 32 . Therefore, when the container 20 is tilted, it is possible to more reliably prevent the shaft 54 from coming out of the longitudinal hole 32, and to more reliably prevent the handle 50 from being released. .

According to the present embodiment, the handle 50 is provided with a stopper 56 formed on the distal end side of the shaft 54, but in a state in which the handle 50 is tilted backward, the protruding portion 56B of the stopper 56 is located inside the vertical hole 32 when viewed in the axial direction of the shaft 54. Therefore, it is easy to pass the stopper 56 through the shaft hole 30, and the handle 50 can be easily attached to the container 20. When the handle 50 is lifted upright, the protruding portion 56B of the stopper 56 overlaps the peripheral portion of the longitudinal hole 32 of the container 20 when viewed in the axial direction of the shaft 54. Therefore, even if the knob 50 is displaced in the axial direction of the shaft 54, the protruding portion 56B of the stopper 56 abuts against the peripheral portion of the vertical hole 32, so that the shaft 54 moves away from the shaft hole 30. , and the handle 50 is prevented from falling out of the container 20 . Therefore, the handle 50 is difficult to come out of the container 20.

According to the present embodiment, the container 20 has an inverted U-shaped reinforcing rib 34, and the shaft 54 is a reinforcing portion inserted inside the reinforcing rib 34 when the handle 50 is lifted upright. (58) has. Therefore, when the container 20 is tilted, the force applied to the container 20 from the handle 50 is supported not only by the front edge 32f of the longitudinal hole 32 but also by the reinforcing rib 34. Since the peripheral portion of the vertical hole 32 is not easily deformed, the shaft 54 is further prevented from deviating from the vertical hole 32. Accordingly, when the container 20 is tilted, it is possible to more effectively prevent the handle 50 from being unfixed.

According to this embodiment, the container 20 further has transverse ribs 36A extending from the reinforcing ribs 34 to the front and rear of the vertical hole 32 . Therefore, the peripheral portion of the vertical hole 32 is more difficult to deform, and the shaft 54 is prevented from coming out of the vertical hole 32 more reliably. When the container 20 is tilted, the fixation of the handle 50 can be more effectively prevented from being released.

In the portable toilet 1, water is collected in the bucket 10 to reach a predetermined water level before use. As shown in FIG. 10 , if the bottom wall 24 of the container 20 is inclined upward toward the front, it becomes easy to secure the water level in the container 20 when 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-clamping plate 23 protruding forward from the front of the outer circumferential wall 22C. For this reason, when the container 20 is tilted forward and the sewage is discharged, the sewage flows down from the front end of the liquid-removing plate 23. The movement of sewage along the outer circumferential wall 22C or the front circumferential wall 26B is suppressed. Contamination of the outer circumferential wall 22C and the front circumferential wall 26B can be suppressed. Therefore, contamination of the outer circumferential wall 22C and the front circumferential wall 26B of the container 20 due to discharge of filthy water can be suppressed.

<Other Embodiments>

As mentioned above, although one embodiment of this invention was described, the said embodiment is only an example. The present invention can be implemented in various other forms. Next, examples of other embodiments are briefly described.

In the above embodiment, the stopper 56 is inserted into the shaft hole 30 in a state in which the handle 50 is tilted backward (see FIG. 23), but as shown in FIG. 30, the handle 50 is moved forward. You may be comprised so that the stopper 56 may be inserted into the shaft hole 30 in the state which fell down. That is, the stopper 56 may be formed so that the protruding portion 56B may be located inside the vertical hole 32 when viewed from the axial direction when the handle 50 is knocked forward. In this case, the handle 50 can be attached to the container 20 by knocking the handle 50 forward. When the container 20 is attached to the toilet body 2 or placed on a floor surface or the like, when the handle 50 is tilted backward, the protrusion 56B of the stopper 56 is located below the round hole 31 Thus, the protruding portion 56B can be engaged with the lower portion of the circular hole 31 . Therefore, it is possible to prevent the handle 50 from being pulled out of the container 20 not only when the handle 50 is lifted but also when the handle 50 is knocked down backward.

As shown in Fig. 3, in the above embodiment, the inlet is not formed in the upper edge 22 of the container 20, but as shown in Fig. 31, the front end of the upper edge 22 of the container 20 An inlet 29 concave downward may be formed in the portion. Accordingly, when the container 20 is tilted forward, dirty water is intensively discharged from the inlet 29 . Therefore, it is possible to prevent the filthy water from scattering left and right, so that the filthy water can be satisfactorily discharged into the toilet bowl.

The shapes of the bottom wall 24 and the circumferential wall 26 of the container 20 described above are only examples and are not limited at all.

The cross-sectional shape of the shaft 54 is not limited to a rectangular shape. As the cross-sectional shape of the shaft 54, any shape having linear first shaft edges 54a and second shaft edges 54b can be adopted.

The vertical length H32b of the rear edge 32b of the vertical hole 32 may be equal to the length H54a of the first shaft edge 54a or longer than the length H54a of the first shaft edge 54a. .

The vertical length H32f of the front edge 32f of the vertical hole 32 may be equal to or smaller than the hole width W32 of the vertical hole 32 .

The lengths of the first shaft edge 54a and the second shaft edge 54b of the shaft 54 may be equal to or smaller than the lengths of the third shaft edge 54c and the fourth shaft edge 54d.

The reinforcing rib 34 may not be present. The transverse ribs 36A or 36B may be omitted.

The length L20f in the front-back direction between the front end 20f of the container 20 and the shaft hole 30 is the same as the length L20b in the front-back direction between the rear end 20b of the container 20 and the shaft hole 30. It may be used, or it may be shorter than the length (L20b).

The liquid-removing plate 23 of the container 20 may not be present.
