Corresponding to the lock hole 51a, the upper support column 52 has a lock claw support hole 52b.
The lock member 53 is an example of a so-called E-lock member that includes a lock claw 53a and a ring portion 53b that elastically contacts the outer periphery of the upper support column 52 at the center.
Accordingly, the height can be adjusted by slidingly selecting the lock hole 51a of the base column 51.
The lower end portion of the upper column 52 has a male screw portion 52d, and can be fastened and fixed to the base column 51 by screwing a tightening ring 54 having a female screw portion inside.

  The portable toilet according to the present invention has a compact structure by resin-molding the toilet body 10 and the leg 50 supporting the toilet body 10 as separate members.

Next, an example of the mounting structure of the casters 57 will be described with reference to FIGS.
6 (a) to 6 (c) show a state where the caster 57 is attached to the main leg, and FIGS. 6 (d) to 6 (g) show that the auxiliary leg 55 is attached to the lower part of the main leg. 55 shows a state in which casters 57 are attached.
At the bottom of the base column 51, there is a mounting portion 51b of a caster 57, and the caster 57 has a structure as shown in FIG.
7A is a front view of the caster 57, and FIG. 7B is a bottom view.
The caster 57 is provided with a shaft portion 57c spaced from the arcuate mounting piece 57b by a predetermined distance and mounted with a wheel 57a, and the mounting portion 51b of a concave caster provided with the mounting piece 57b on the bottom of the base column 51. The wheel 57a is attached in a state of being detached from the bottom surface by being attached to the wheel.
When the toilet body 10 is slightly tilted rearward, the wheels 57a of the casters 57 come into contact with the floor surface to facilitate movement.
The auxiliary leg 55 is attached to the bottom of the main leg when it is not sufficient to adjust the height of the main leg. In this case, the height of the seating surface becomes high and the center of gravity becomes unstable. Because of fear, the outer shape of the auxiliary leg portion 55 is larger than the outer shape of the bottom portion of the main leg portion (the bottom portion of the base column 51).
The auxiliary leg portion 55 includes an insertion portion 55 a that is inserted into the bottom opening portion of the base column 51 and an attachment positioning portion 55 b.
When the auxiliary leg 55 is attached to the bottom opening of the base column 51, if the positioning around the circumference is not determined, the direction of the caster 57 attached to the auxiliary leg 55 is not constant.
Therefore, in this embodiment, a caster mounting opening 51c of the base column 51 is used as a positioning recess provided at the bottom of the base column 51, and the mounting positioning unit 55b is a caster mounting opening of the base column 51 constituting the main leg. The shape fits with 51c.
Even when the caster 57 is attached to the auxiliary leg 55, when using the portable toilet, the wheel 57a is released without touching the floor so that the portable toilet can be stably placed. It touches the floor and is easy to move.
Here, when the size of the outer shape of the auxiliary leg portion 55 is larger than the outer size of the bottom portion of the main leg portion and the stability is ensured, the caster 57 is attached as it is to the side portion of the auxiliary leg portion having the larger outer shape. The distance from the bottom center of the leg portion to the wheel shaft portion 57c of the caster 57 is increased.
However, as the distance from the bottom center of the leg to the shaft 57c of the caster 57 increases, the center of gravity of the portable toilet and the distance to the shaft 57c of the caster 57 also change, and the force required to move the portable toilet tilted. In addition, there is a difference from the case where the auxiliary leg portion is not attached.
Therefore, in the present invention, a concave caster mounting portion 55c having the same center radius as the caster mounting opening 51c of the main leg portion is formed on the bottom surface of the auxiliary leg portion 55, and the caster 57 is mounted and attached to this portion. I did it.
6 (c) and (f), the distance L from the center of the bottom surface to the wheel shaft 57c becomes the same even though the auxiliary leg portion 55 has a large outer shape. Improved mobility.

Next, FIG.8 and FIG.9 shows the attachment structural example of the storage shelf 60. FIG.
FIG. 8A shows a side view of the storage shelf 60, and FIG. 9 shows a partial view of the storage shelf 60 viewed from the back of the portable toilet.
As shown in FIG. 8 (b), the bottom surface of the toilet body 10 has a hook portion 10c that is substantially L-shaped in side view, while the upper portion of the storage shelf 60 has a locking hole 61. The locking hole 61 is hooked on the hook portion 10 c of the toilet main body 10.
As shown in FIG. 9, a fixed piece 52c protrudes from the side portion of the leg portion 50, and a protruding portion protrudes downward from a fixed portion 62 provided in the storage shelf 60 in a fixed hole 52e provided in the fixed piece. 62a is fitted.
As a result, when the upper part of the leg part 50 is connected to the connecting recess 13 of the toilet body main part, the storage shelf 60 supports the toilet bowl 60 so that the fixed part 62 of the storage shelf 60 is supported from below by the fixing part composed of the fixing piece 52c of the leg part 50. It is fixed to the lower surface of the main body 10.
Therefore, since the storage shelf 60 can be attached to the toilet main body without using a fixing member such as a screw, the assembly workability is good.
In addition, the weight of the storage shelf can be supported from below by a fixing portion provided on the leg portion, and the storage shelf can be firmly fixed with a simple structure as compared with a structure in which the storage shelf is suspended below the toilet body main body portion.
