Definitions
- 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.
- the portable toilet is equipped with a removable bucket placed below the toilet seat.
- the user or a caregiver (hereinafter collectively referred to as a user) removes the bucket from the bucket body and carries the bucket 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.
- the user can carry the bucket by moving while grasping the handle.
- 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.
- the container may shake and sewage may be scattered to the outside when the user grabs the handle and carries the bucket.
- the container may tilt and sewage may spill.
- Patent Document 1 discloses a bucket provided with such a locking mechanism, although it is not for a portable toilet.
- the locking mechanism disclosed in Patent Document 1 is composed of a shaft hole 501 formed in the container 500 and a shaft 511 provided in the handle 510.
- the shaft hole 501 is formed in an eggplant shape, and is composed of a circular hole 502 and a vertical hole 503 above the circular hole 502.
- the shaft 511 of the handle 510 has a rectangular cross-sectional shape.
- FIG. 32 (a) when the handle 510 is tilted down, the shaft 511 is located inside the circular hole 502, so that the handle 510 is rotatable.
- FIG. 32 (b) when the handle 510 is raised and lifted, the shaft 511 moves from the circular hole 502 to the vertical hole 503, so that it cannot rotate.
- the handle 510 is non-rotatably fixed to the container 500.
- the user When draining sewage from the bucket to the toilet bowl, the user first positions the container 500 above the toilet bowl 520 while grasping the handle 510, as shown in FIG. 33 (a). At this time, as shown in FIG. 33 (b), the shaft 511 of the handle 510 is fitted in the vertical hole 503, and the rotation of the handle 510 is restricted. Next, as shown in FIG. 34 (a), the user tilts the container 500 while grasping the handle 510. In a bucket provided with a locking mechanism, the handle 510 is non-rotatably fixed to the container 500, so that the user tilts the handle 510 together with the container 500. At this time, a force that tilts from the vertical hole 503 acts on the shaft 511 of the handle 510 (see FIG. 34 (b)).
- the shaft 511 gradually tilts and slides from the vertical hole 503 toward the circular hole 502. Then, when the degree of inclination becomes large, the shaft 511 deviates from the vertical hole 503 (see FIG. 35 (b)). When the shaft 511 is disengaged from the vertical hole 503, the handle 510 is released from being fixed, and the container 500 is suddenly tilted (see FIG. 35 (a)). As a result, the sewage is vigorously discharged toward the toilet bowl 520, causing a problem that the sewage is scattered outside the toilet bowl 520.
- An object of the present invention is that the handle can be fixed so as not to rotate with respect to the container while keeping the vertical dimension of the shaft hole of the container small, and when the container is tilted while grasping the handle, sewage is discharged. It is to provide a portable toilet bucket in which the handle is not released and a portable toilet equipped with the bucket.

Abstract
Description
ポータブルトイレ1は、トイレ本体2と、トイレ本体2に着脱可能に装着されるポータブルトイレ用バケツ(以下、単にバケツという)10とを備えている。
まず、トイレ本体2について説明する。トイレ本体2は、椅子部3と、椅子部3を支持する脚4と、便座5と、背もたれ6と、左右の肘掛け7と、蓋8とを備えている。椅子部3は、上方に開口した箱状に形成されている。バケツ10は、椅子部3の内側に装着される。便座5は、椅子部3の後部に回動可能に取り付けられている。便座5を前方に回動させると、便座5を水平に倒すことができ、利用者は便座5の上に座ることができる。便座5を上方に回動させると、便座5を立たせることができ、椅子部3の内側を開放することができる。便座5を立たせた状態とすることにより、バケツ10を椅子部3から上方に取り外すことができ、また、バケツ10を椅子部3に向けて上方から取り付けることができる。
次に、バケツ10について説明する。以下のバケツ10に関する説明では、前、後、左、右とは、バケツ10がトイレ本体2に装着されているときに、便座5に座った利用者から見た前、後、左、右の各方向をそれぞれ意味するものとする。上、下は、バケツ10が水平面に置かれたときの上、下をそれぞれ意味するものとする。図面中の符号F、Re、L、R、U、Dは、それぞれ前、後、左、右、上、下を表すものとする。
図3、図4、図5、図6は、それぞれ容器20の平面図、左側面図、背面図、底面図である。図7は容器20の縦断面図であり、図5のVII-VII線断面図である。図8は容器20の水平断面図であり、図4のVIII-VIII線断面図である。図7に示すように、容器20は、底壁24と、底壁24から上方に延びる周壁26と、周壁26の上方に位置する上縁部22と、底壁24の下側に設けられた環状脚28とを備えている。
図16に示すように、取っ手50は、柄部51と、柄部51の両端部に設けられた係合部52とを有している。係合部52は、容器20の軸孔30に係合する部分である。図17に示すように、係合部52は、柄部51の先端部から内側に延びている。係合部52は、軸54と、軸54の内側に設けられたストッパ56と、軸54の外側に設けられた補強部58とを有している。ストッパ56は、軸54の先端側に設けられている。詳しくは、取っ手50の右側の係合部52は、補強部58と、補強部58の左方に設けられた軸54と、軸54の左方に設けられたストッパ56とを有している。取っ手50の左側の係合部52は、補強部58と、補強部58の右方に設けられた軸54と、軸54の右方に設けられたストッパ56とを有している。
利用者がポータブルトイレ1を使用すると、バケツ10に汚水が溜める。利用者はバケツ10の汚水を捨てるために、まず、取っ手50を立てて持ち上げることにより、バケツ10をトイレ本体2から取り外す。この際、取っ手50の軸54が容器20の縦孔32に嵌まり込み、取っ手50は容器20に回動不能に固定される。そのため、利用者は、バケツ10を容易に取り外すことができる。
次に、本実施形態によってもたらされる様々な効果について説明する。
以上、本発明の一実施形態について説明したが、前記実施形態は一例に過ぎない。本発明は、他にも様々な形態にて実施することができる。次に、他の実施形態の例について簡単に説明する。
