DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention is shown in FIGS.
It is shown in FIG. As shown in FIGS. 1 and 2, a portable toilet
A toilet tub (4) is suspended from the upper opening (3) of the toilet body (2) of (1), and a toilet seat (5) is placed around the periphery of the opening (3). Has an upper lid (6) attached thereto. The toilet seat
The rear ends of both (5) and the upper lid (6) are pivotally connected to the upper rear edge of the toilet body (2) by hinges (7).

The upper lid (6) has a front half (8) and a rear half (9)
The handle (10) is provided on the upper surface of the first half (8).
As shown in FIG. 6, an L-shaped bearing bracket (11) is suspended from the front edge of the rear half (9),
A straight plate-shaped bearing bracket (12) is suspended from the rear edge of (8), and both bearing brackets (11, 12) are rotatably connected by a shaft (13) to form a hinge (14). The axis (13) of the hinge (14) is offset from the front edge of the rear half (9) from the front, so that the front lid (6) is folded upright as shown in FIG. The trailing edge of 8) is higher than the leading edge of the latter half (9), and as shown in FIG.
When viewed from the front of (1), the hinge of the upper lid (6) in a folded state
The part (14) is set so as to be hidden by the rear edge of the front half part (8) so as not to be seen.

A backrest (1) is provided at the rear edge of the toilet body (2).
5) is installed. The backrest (15) comprises an upper side (16) and both sides (17, 17). As shown in FIG. 4, mounting cylinders (18, 18) extend from lower ends of both sides (17, 17). Have been. As shown in FIG. 8, the mounting cylinder (18) is provided with a pair of front and rear cut grooves (19) from the lower end, and claws (20) are protruded from left and right of the lower end of the mounting cylinder (18). I have.

As shown in FIGS. 4 and 8, the backrest
The mounting cylinders (18, 18) on both sides (17, 17) of (15) are
It is inserted into the mounting outer cylinder (21) which is open at the rear part on both sides of the upper surface of (2). As shown in FIGS. 9 and 10, the mounting outer cylinder (21) is provided with ribs (22, 23, 24, 25) in the toilet body (2).
Is reinforced and supported by the core tube from the bottom center
A notch (27) is provided on both the left and right sides of the bottom, and a mounting cylinder (18) on both sides (17) of the backrest (15) is provided on the mounting outer cylinder (21). 10, the claw (20) of the mounting cylinder (18) engages with the notch (27) of the mounting outer cylinder (21) as shown in FIG.

In the side portions (17, 17), a fixing tube (28) is inserted into the mounting tube (18) from above as shown in FIGS. 8, 9, and 10. A substrate (29) is provided at the upper end of the fixed cylinder (28), and a pair of front and rear cut grooves (30, 30) are provided from the lower end. There are projected, the fixed tube (28) in a state with interpolation to the mounting cylinder (18), the pawl (31) of the fixed cylinder (28) as shown in FIG. 9 mounting cylinder (18) Engaging with the upper end of the cut groove (19). In this way, the mounting cylinder (18) is prevented from being deformed such that the width is reduced by the fixing cylinder (28) through the cut groove (19), and the backrest (15)
Is attached to the rear edge of the toilet body (2) via mounting cylinders (18, 18) on both sides (17, 17).

[0010] The backrest (15) has both sides (17, 17) warped rearward. Therefore, as shown in FIG. 5, the position of the upper side (16) of the backrest (15) is It is offset backward by a width L from the hinge (7) between the toilet seat (5) and the upper lid (6). The inner space of the backrest (15) is
As shown in FIGS. 2 and 5, when the folded upper lid (6) is flipped rearward, the upper lid (6) is set so as to be able to pass through the inside of the backrest (15). Then, as shown in FIGS. 3 and 5, the toilet seat (5) is raised upward, and the backrest (1) is raised.
5) In a state where the upper end of the toilet seat (5) is in contact with the upper side portion (16) of the toilet seat (5), the raising angle θ of the toilet seat (5) is 90 ° or more,
The toilet seat (5) is stably supported on the upper side (16) of the backrest (15) without any support means in the raised state.

Armrests (32, 32) are attached to both sides of the upper surface of the toilet body (2). The armrest (32, 32)
Is an arm support part (33), support rods (34, 34) vertically suspended from the front and rear of the arm support part (33), and a base that is passed over the root end of the front and rear support rods (34, 34). 9 and 11, a mounting cylinder (36, 36) projecting forward and backward in the casing (35) and a screw cylinder (37, 37) having a screw through hole. ) And the armrests (32, 32)
The casing (35) is fitted in fitting recesses (38, 38) on both sides of the upper surface of the toilet body (2) as shown in FIG. In this state, the mounting cylinder (36, 36) in the casing (35) is
38) is fitted and positioned on the positioning projections (39, 39) standing upright from the bottom of the screw cylinder (37, 39) in the casing (35).
37), and a pair of front and rear support blocks (41, 41) standing upright from the bottom of the fitting recesses (38, 38).
The screw holes (4) of the bases (42, 42) provided on the front and rear sides of
The screws (40, 40) are screwed into and tightened to (3, 43).

In this way, the armrests (32, 32)
Are detachably mounted on both sides of the upper surface of the toilet body (2). When the armrests (32, 32) are mounted, the rear ends of the arm support portions (33) of the armrests (32, 32) are connected to both side portions (17, 17) of the backrest (15), and FIG. As shown in FIG. 7, a ridge (44) formed on the lower side of the rear end of the arm support portion (33) has both side edges (17, 17) of the backrest (15) and a front edge step (45). ) Is fitted in the fitting groove (46) formed in the middle of the above.
In this way, the backrest (15) and the armrests (32, 32) are integrated, and the user's body is moved to the armrests (32, 32).
And the backrest (15).

When the armrest (32) is unnecessary or when the user moves from the bed on the side to the toilet (1), the screw (40) is removed, and the armrest (32) is moved to the toilet body ( 2) can be removed from both sides of the upper surface, but when the armrest is removed, the fitting recess of the toilet body (2)
The lid (47) is closed so that (38) is not exposed. The lid (47)
As shown in FIG. 11, fitting cylinders (47A) are provided on the front and rear sides of the lower surface, and when the fitting recess (38) is closed with the lid (47), the lid (4
The fitting cylinder (47A) of (7) is provided with positioning projections (39, 39) of the fitting recess (38).
39), and furthermore, the support block (41, 41) of the fitting recess (38).
41) supports the lower surface of the lid (47).

At the four corners on the lower surface of the toilet body (2), legs (48) are attached. The legs (48) are screw-in type and can be adjusted in height. Therefore the portable toilet
In (1), the height can be adjusted according to the user's body shape, and can be tilted forward or backward according to the preference or the tilt of the foundation.

Further, the front surface (49) of the toilet body (2) is inclined so as to enter inside as it goes down,
Since both sides of (49) are recessed inward, the knee can be bent sharply when the user rises from the toilet (1),
Easy to rise. In addition, the assistant inserts his / her feet into the recessed portions on both sides of the front surface (49), so that the user can easily assist when standing up. Further, on the side of the toilet body (2), a lid plate (50) of a storage section for storing toilet paper and a deodorant is provided.
Is attached.

[0016]

According to the present invention, the screw (40) is inserted from above into the screw through hole of the base (35) at the root end portion of the armrest (32) and provided on both sides of the upper surface of the toilet body (2). Screw holes (4
Since the armrest (32) is attached to the toilet body (2) by screwing and tightening the screw (40) to 3), even if the user is sitting on the toilet, the screw (40) is removed from the outside and the armrest (32) is removed. Can be removed.
