The upper lid (6) has a front half (8) and a rear half (9).
The upper half of the first half (8) is divided into a handle (10).
As shown in FIG. 6, an L-shaped bearing bracket (11) is hung vertically from the front edge of the rear half (9).
(8) A straight plate bearing bracket (12) is hung from the rear edge of the bearing, 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) to the front, so that the upper half (6) is folded upright as shown in FIG. 8) The trailing edge is higher than the leading edge of the latter half (9), and as shown in FIG.
When the (1) is viewed from the front, the hinge of the upper lid (6) in the folded state
The part (14) is hidden by the rear edge of the front half part (8) so that it cannot be seen.

At the rear edge of the toilet body (2), the backrest (1
5) is installed. The backrest (15) is composed of an upper side part (16) and both side parts (17, 17). As shown in FIG. 4, the mounting cylinders (18, 18) are extended from the lower ends of both side parts (17, 17). Has been done. 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 the left and right of the lower end of the mounting cylinder (18) have projecting claws (20). There is.

As shown in FIGS. 4 and 8, the backrest
The mounting cylinders (18, 18) on both sides (17, 17) of (15) are the toilet body
It is inserted into the mounting outer cylinder (21) that is open at the rear of both sides of the upper surface of (2). As shown in FIGS. 9 and 10, the mounting outer cylinder (21) has ribs (22, 23, 24, 25) in the toilet body (2).
It is reinforced and supported by the core tube from the bottom center.
(26) is upright, notches (27) are provided on the left and right sides of the bottom, and the mounting cylinder (21) is attached to the mounting outer cylinder (21) on both sides (17) of the backrest (15). As shown in FIG. 10, the claws (20) of the mounting cylinder (18) are engaged with the notches (27) of the mounting outer cylinder (21) when inserted into the mounting cylinder (18).

Inside the both side portions (17, 17), a fixed cylinder (28) is further inserted into the mounting cylinder (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, and a claw (31) is provided at the upper end of the cut groove (30). And the claws (31) of the fixed cylinder (28) are attached to the mounting cylinder (18) as shown in FIG. 9 with the fixed cylinder (28) inserted in the mounting cylinder (18). Engage with the upper end of the cut groove (19). In this way, the mounting cylinder (18) is prevented from being deformed by the fixed cylinder (28) such that the width thereof is reduced through the cut groove (19), and the backrest (15)
Is attached to the rear edge of the toilet body (2) via the attachment cylinders (18, 18) on both sides (17, 17).

Both sides (17, 17) of the backrest (15) are curved backward, so that the position of the upper side (16) of the backrest (15) is as shown in FIG. It is offset rearward by a width L from the hinge (7) between the toilet seat (5) and the upper lid (6). Also, the inner space of the backrest (15) is
When the folded upper lid (6) is flipped up rearward as shown in FIGS. 2 and 5, the upper lid (6) is set so that it can pass through the inside of the backrest (15). Then, as shown in FIG. 3 and FIG. 5, raise the toilet seat (5) upward, and set the backrest (1)
5) With the upper edge of the toilet seat (5) in contact with the upper side (16), the rising angle θ of the toilet seat (5) is 90 ° or more,
The toilet seat (5) is stably supported on the upper side portion (16) of the backrest (15) without raising any supporting means in the raised state.

Armrests (32, 32) are attached to both upper surfaces of the toilet body (2). The armrest (32,32)
Is the arm support part (33), the support rods (34, 34) suspended from the front and rear of the arm support part (33), and the base that is passed to the root ends of the front and rear support rods (34, 34). (35), a mounting cylinder (36, 36) projecting forward and backward in the casing (35) as shown in FIGS. 9 and 11, and a screw cylinder (37, 37) having a screw through hole. ) And the armrest (32,32)
The casing (35) is fitted into the 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 tube (36, 36) in the casing (35) is fitted into the fitting recess (38,
(38) is fitted and positioned by the positioning protrusions (39, 39) standing upright from the bottom, and the screw tube (37,
Insert the screws (40, 40) into the (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
Tighten the screws (40,40) by screwing them on 3,43).

In this way, the armrest (32, 32)
Are detachably attached to both sides of the upper surface of the toilet body (2). When the armrests (32, 32) are attached, 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), as shown in FIG. As shown in FIG. 7, the ridges (44) formed on the lower side of the rear end of the arm support (33) have 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.
In this way, the backrest (15) and the armrests (32, 32) are integrated, and the user's body is attached to the armrests (32, 32).
And it is stably held by the backrest (15).

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

Legs (48) are attached to the four corners of the lower surface of the toilet body (2), and the legs (48) are of a screw-in type so that the height can be adjusted. Therefore the portable toilet bowl
In (1), the height can be adjusted according to the body shape of the user, and can be tilted forward or backward depending on the preference or the inclination of the foundation.

Further, the front surface (49) of the toilet body (2) is inclined so as to enter inside as it goes downward, and the front surface (49) is further inclined.
Since both sides of (49) are recessed inward, the knee can be bent at an acute angle when the user stands up from the toilet bowl (1),
It becomes easier to stand up. Further, the caregiver can insert his / her feet into the concave portions on both sides of the front surface (49) to easily assist the user when standing up. Further, on the side surface of the toilet body (2), a lid plate (50) for storing the toilet paper and deodorant is stored.
Is being worn.

[0016]

According to the present invention, since the upper side of the backrest of the portable toilet is offset rearward from the toilet seat and the upper lid pivoting position, the toilet seat and the upper lid are flipped up rearward to stand up, and the toilet seat is placed on the backrest. In the leaned state, the toilet seat raising angle becomes larger than 90 °, so that the toilet seat can be leaned on the backrest in a stable manner. Furthermore,
When removing the mrest , cover the fitting recess of the toilet body.
Since it is closed with, make sure that the fitting recess is not exposed.
Rukoto can be. Furthermore, if the upper lid can be folded and flipped up in the folded state and passed through the inside of the backrest,
When the toilet seat is raised, there is no interference with the upper lid.
