Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable toilet. 2. Description of the Related Art Conventionally, a toilet bowl is provided at an opening on an upper surface of a toilet body, a toilet seat and an upper lid are pivotally mounted on an upper surface, and wheels and wheels whose relative height relationship can be changed on a lower surface. A portable toilet provided with a shoe is disclosed in, for example, Japanese Patent Laid-Open No. 5-111.
No. 443. [0003] However, in such a portable toilet, in order to prevent unintentional movement at the time of sitting or standing, at least the wheels and the brake shoes are required. There is a problem that a mechanism for moving one of them up and down is required, and it is necessary to perform the trouble of grounding and releasing the brake shoe before and after the movement. An object of the present invention is to solve the above-mentioned conventional problems and to provide a portable toilet capable of moving and installing the portable toilet without any trouble. In the portable toilet of the present invention, a substantially comb-shaped concave groove is formed in a side surface of an upper cylindrical portion, and the groove is projected obliquely upward from a flange edge at a lower end. A pair of substantially tooth-rod-like supporting legs having wheels rotatably supported on the arm rods are drilled at the four corners of the toilet body, and plate-like projections engaging with the lateral grooves of the concave grooves are formed on the peripheral wall. It is characterized in that the two protruding circular holes are inserted and fitted into two adjacent ones so that the wheels do not touch the ground when erected. [0006] In the portable toilet of the present invention, the material of the supporting leg and the supporting leg with wheels is not particularly limited as long as the material has a load strength sufficient to support the weight of the user. Hard thermoplastic resins such as glass fiber reinforced unsaturated polyester (FRP), acrylonitrile-butadiene-styrene (ABS), and polyamide (PA) are exemplified. The shape of the substantially comb-shaped concave groove formed on the side surface of the upper cylindrical portion of the supporting leg and the supporting leg with wheels is not particularly limited, but the width of the vertical groove portion whose upper end is open is a circular hole. It is preferable that the width is slightly larger than the width of the plate-like projection so that the plate-like projection protruding from the peripheral wall can be smoothly inserted. One end is closed and the length of the horizontal lateral groove portion, which is vertically arranged at equal intervals, is closed so that a load can be dispersed and supported over the entire plate-like projection when the rotation is made. It is made larger than the width of the projection, so that the calculation of the adjustment height is easy,
Preferably, the pitch is 10 mm. Although the number of the grooves is not particularly limited, three to four grooves are required so that the angle of rotation for engaging the plate-like projection inserted into the vertical groove with the horizontal groove may be small. Are preferably engraved at equal intervals. It is preferable to add an ordinal or a different color point to the side of the lateral groove so that the lateral groove can be easily visually recognized in which lateral groove the plate-like projection is engaged.
The ordinal numbers or color points do not necessarily need to be added to all the horizontal groove portions as long as the horizontal groove portions can be identified, and may be added every other groove or the like. [0011] A synthetic rubber non-slip may be attached to the ground surface of the support leg and the support leg with wheels so as to prevent damage to the floor surface and lateral displacement. Irregularities such as a radial shape and a concentric shape may be provided on the bottom surface of the slip stopper. The shape of the arm rod projecting obliquely upward from the flange edge at the lower end of the support leg with wheels is not particularly limited as long as the wheel supported at the time of erecting does not touch the ground. The upper surfaces of the semicircular plate-shaped projections may be connected by a substantially semicylindrical curved plate. The material of the arm rod is not particularly limited.
A hard thermoplastic resin such as ABS or PA of the same material as the support legs with wheels may be used. The method of fixing the arm rod to the supporting leg with wheels is not particularly limited, and may be any of, for example, fusion, fitting, and screwing. The support legs with wheels are inserted into two adjacent circular holes formed in the four corners of the toilet body so that the wheels can contact the ground by tilting the toilet body toward the wheels. When a handrail or a backrest is provided upright on the upper surface, there is an advantage that the handrail or the backrest can be gripped and moved as a handhold. The shape of the wheel is not particularly limited.
Any of a roller shape, a ball shape, a disk shape and the like may be used. The material of the wheel is not particularly limited, and may be, for example, any of a hard synthetic resin and a synthetic rubber.

In the portable toilet of the present invention, the material of the bottom plate of the toilet body is not particularly limited, and examples thereof include hard thermoplastic resins such as PP and HDPE made of the same material as the toilet body. The method of fixing the bottom plate to the toilet body is not particularly limited,
For example, any of fusion, fitting, and the like may be used. On the upper surface of the toilet body, there may be provided an armrest for assisting the user in sitting and standing, and a backrest capable of taking a relaxed posture when the user is seated. The armrest and the backrest may be formed integrally with the toilet body or may be formed separately and detachable as necessary. In the latter case, the material of the armrest and the backrest is not particularly limited as long as it has a sufficient load strength to support the weight of the user. For example, synthetic resin-coated metal, wood, ABS, Hard thermoplastic resin such as PA, FRP and the like can be mentioned. In the portable toilet of the present invention, the material of the toilet tank supported by the opening on the upper surface of the toilet body is not particularly limited. For example, a metal such as aluminum or a hard thermoplastic such as PP or HDPE is used. Resins. The shape of the toilet tank is not particularly limited. For example, a folded edge for preventing deformation is provided around the opening,
Preferably, the bottom wall is inclined forward so that the contents can be concentrated, and a handle is projected behind the bottom wall outer surface so that the contents can be easily inclined forward when discarding the contents. A hand may be pivotally attached to the folded edge so that the toilet tank can be easily carried when the contents are discarded. Since the carrying hand is rotated rearward of the toilet tank when the contents are discarded, it may be formed in a substantially zigzag shape or a substantially semicircular arc shape according to the planar shape of the rear half of the toilet tank. The material of the hand is not particularly limited, for example, metal,
A hard thermoplastic resin can be used. In the portable toilet of the present invention, the material of the toilet seat rotatably mounted on the upper surface of the toilet main body has a sufficient load strength to support the weight of the user. There is no particular limitation as long as it is not particularly limited. For example, a hard thermoplastic resin such as PP or ABS may be used, and a heater may be incorporated inside so as not to feel unpleasant cold when sitting in winter. The means for attaching the toilet seat is not particularly limited. For example, two projections protruding from the upper surface of the toilet body and a circular hole are formed in the side surface of the base end of the toilet seat, and the toilet seat is pivoted by the rotating shaft. Even if it is worn, even if a rod-shaped projection is protruded on one of the inner surface of the adjacent protrusion and the outer surface of the base end portion, and a circular hole is drilled on the other, both are pivotally attached, Either may be used. In the portable toilet of the present invention, the material of the upper lid rotatably mounted on the upper surface of the toilet body is not particularly limited. For example, a hard thermoplastic resin such as PP or HDPE may be used. No. The shape of the upper lid is determined in accordance with the shape of the toilet seat, and is not particularly limited as long as it can cover the toilet seat. The divided front half and rear half may be foldably connected. The means for attaching the upper lid is not particularly limited. For example, two projections projecting from the upper surface of the toilet body and a circular hole are formed on the side surface of the base end of the upper lid, and the shaft is rotated by the rotating shaft. Even if it is worn, even if a rod-shaped projection is protruded on one of the inner surface of the adjacent protrusion and the outer surface of the base end portion, and a circular hole is drilled on the other, both are pivotally attached, Either may be used.
