Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a portable toilet.

[0002]

2. Description of the Related Art Conventionally, a pair of armrests having a base extended to the root ends of two front and rear vertical rods vertically suspended from a horizontal rod are detachably mounted on both sides of an upper surface of a toilet body from the outside. The installed portable toilet is disclosed, for example, in Japanese Patent Application Laid-Open No. 11-267068.

[0003]

However, in such a portable toilet, the fitting recess of the base, which is inserted over the root end of the vertical rod, allows the user to carry the container from the side at the time of removal. There is a problem that smooth movement when transferring to the toilet is hindered, and extra parts such as a lid for closing the fitting recess are required.

The present invention solves the above-mentioned conventional problems, and allows the armrest to be attached and detached from the outside without adding extra parts.
It is an object of the present invention to provide a portable toilet that allows a user to smoothly transfer from a side.

[0005]

According to the portable toilet of the present invention, a tubular body having a flange on the inner periphery at the upper end and a male screw engraved on the outer peripheral surface is suspended from the horizontal rod of the armrest. It is fixed to the two front and rear vertical rods so as to be rotatable in the circumferential direction, and is screwed to a female screw engraved at the upper end of a hole formed on both sides of the upper surface of the toilet body. And

[0006] In the portable toilet of the present invention, the material of the toilet body is not particularly limited.
P) and hard thermoplastic resins such as high-density polyethylene (HDPE).

[0007] A backrest may be provided upright on the toilet body so as to take a relaxed posture when seated. The backrest may be formed integrally with the toilet body, may be formed separately, and may be detachable as necessary.

[0008] In the portable toilet of the present invention, the material of the armrest is not particularly limited as long as it has sufficient load strength to support the weight of the user. And hard thermoplastic resins such as fiber-reinforced synthetic resin (FRP), acrylonitrile-butadiene-styrene (ABS), and polyamide (PA).

It is preferable that the front vertical rod insertion holes formed on both sides of the upper surface of the toilet main body are formed so as to be located behind the front surface of the toilet main body. This is because, when the front vertical rod is erected near the front end of the toilet body, the thighs are pressed inward when seated and are cramped.

[0010] Preferably, the horizontal bar of the armrest protrudes to the front of the toilet body. If the front end of the horizontal rod is located behind the front end of the toilet body, the user is forced to take an unreasonable posture to hold the horizontal rod when standing and sitting.

[0011] When the horizontal rod of the armrest protrudes forward from the front vertical rod, it is preferable that the tip is formed substantially hemispherical. This is because, when the user stands and sits, it is easy to put his / her hand on the tip of the horizontal rod and manage the power.

The cross-sectional shape of the horizontal rod is not particularly limited.
It is preferable that the upper surface is formed in a substantially flat oval shape having a wide, substantially planar shape, a substantially rectangular shape with rounded corners, and the like. This is because the forearm can be placed on the upper surface of the horizontal rod and the body stability can be easily maintained without gripping the horizontal rod when sitting.

In the portable toilet of the present invention, the material of the cylindrical body fixed to the vertical rod so as to be rotatable in the circumferential direction is not particularly limited, and hard heat such as synthetic resin-coated metal, ABS, PA or the like is used. And a plastic resin. Non-slip irregularities may be engraved at the upper end of the outer periphery of the cylindrical body so that the cylindrical body can be easily gripped and rotated with a fingertip.

The means for fixing the cylindrical body to the vertical rod so as to be rotatable in the circumferential direction is not particularly limited. For example, a plurality of substantially zigzag cuts may be formed in the vertical rod at regular intervals. When the flange at the upper end of the tubular body is inserted, the strip bent inward with the base end as a fulcrum returns to its original shape, and the flange that protrudes from the upper end of the outer surface of the strip is formed. May support the flange of the tubular body. A substantially triangular reinforcing ridge may be provided vertically below the flange edge of the ridge.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A portable toilet of the present invention will be described below with reference to the drawings. 1 is a partially exploded perspective view showing an example of the portable toilet of the present invention, FIG. 2 is an enlarged view of a main part of FIG. 1, and FIG.
It is principal part sectional drawing which shows the attachment state of the armrest of the portable toilet shown in FIG.

In FIG. 1, reference numeral 1 denotes a toilet body having a substantially horseshoe-shaped opening formed on an upper surface thereof, and a folded edge (not shown) is provided around a substantially annular step around the opening. A substantially horseshoe-shaped stool tank is supported in plan view.

Above the opening of the toilet tank, a substantially horseshoe-shaped toilet seat having a substantially egg-shaped opening (not shown) and an upper lid 2 that completely covers the toilet seat are independently rotatable up and down. Axle-mounted. The approximately halved front half and rear half of the upper lid 2 are connected to be foldable in two.

A substantially inverted U-shaped backrest 3 in which an elastic body is fixed to the front surface of a horizontal rod connecting the upper ends of two vertical rods, the distal ends of the vertical rods are drilled on both sides of the upper surface of the toilet body 1 at the rear. It is erected by inserting it into the hole.

As shown in FIG. 2, the distal ends of the vertical rods 42 of the pair of armrests 4 each having two front and rear vertical rods 42 vertically extending from the horizontal rod 41 are reduced in diameter. In the reduced-diameter portion, two substantially Japanese-shaped cuts are formed at equal intervals to form a strip 43. At the upper end of the outer surface of the ridge 43, a flange 44 is protrudingly provided.
Below, a substantially triangular reinforcing ridge 45 is vertically provided.

A cylindrical body 5 having a flange edge 51 provided on the inner periphery at the upper end and a male screw 52 engraved on the outer peripheral surface is fitted into the reduced diameter portion of the vertical rod 42 and is shown in FIG. As described above, the flange edge 51 is supported by the flange edge 44 and is fixed so as to be rotatable in the circumferential direction.

When the armrest 4 is erected, the reduced diameter portion at the tip of the vertical rod 42 is removably inserted into the stepped holes 11 formed on both sides of the upper surface of the toilet body 1 to form a cylindrical shape. Male screw 52 of body 5 with stepped hole
What is necessary is just to screw in the female screw 12 carved in the upper end of 11.

[0022]

The portable toilet of the present invention is constructed as described above, so that the armrest can be detached from the outside and the user can smoothly transfer from the side without adding extra parts. Can be done.
