When the portable toilet described in Patent Document 1 and Patent Document 2 is in the folded state, it is necessary to remove the bucket each time. Moreover, it is necessary to set a bucket each time it changes from the folded state to the use state as a toilet. Therefore, it takes time and effort for the user and caregiver when folding or using the toilet. In addition, if the removed bucket is placed near a portable toilet so that it can be used immediately as a toilet, it may be forced to be placed on the floor surface with the bucket exposed. It will be missing.

Also, if the portable toilet does not stand up in a folded state, it must be leaned against walls or furniture when storing and storing the portable toilet. In this case, a place where the portable toilet is stored and stored is limited, and there is a concern that the user needs to place the portable toilet in a place where the user cannot immediately use the toilet, for example, a place far from the bed.

≪Operation of portable toilet 10≫
Next, the operation of the portable toilet 10 will be described. FIG. 10 is a perspective view of the portable toilet 10 in a folded state as viewed from the left diagonal front, and FIG. 11 is a perspective view of the portable toilet 10 in a folded state as viewed from diagonally left rear. FIG. 12 is a right side view of the portable toilet 10 in a folded state.

As described above, the leg part 11 is in a closed leg state in which the lower part of the front leg part 12 and the lower part of the rear leg part 13 approach each other from the open leg state in which the lower part of the front leg part 12 and the lower part of the rear leg part 13 are separated from each other. Can be folded. In addition, the toilet body 40 includes a sideways state where the receiving part 60 receives the bucket 50 with the opening 53 of the bucket 50 facing upward, and a state where the receiving part 60 faces the opening 53 of the bucket 50 rearward. The posture can be changed between the vertically oriented state where the bucket 50 is received. In this embodiment, the operation in which the toilet body 40 is changed from the horizontal state to the vertical state and the operation in which the leg part 11 is changed from the open leg state to the closed leg state are performed in conjunction with each other.

Specifically, as shown in FIG. 8, the front leg portion 12 is connected to the main body frame 61 via a connecting plate 64, and the rear leg portion 13 is connected to the main body frame 61 via a rotating shaft 65a. Yes. When the main body frame 61 is rotated upward to be arranged vertically, the lower part of the front leg part 12 and the lower part of the rear leg part 13 are drawn together in conjunction with the main body frame 61, and both approach each other. As a result, the portable toilet 10 is in the folded state shown in FIGS. In the state in which the portable toilet 10 is folded, the second grounding surface 39b is grounded on each leg of the leg portion 11, so that the portable toilet 10 can be stably and independently provided with the bucket 50 and the accommodating portion 62.

Here, in the portable toilet 10, there is no member that becomes an obstacle of the toilet body 40 in the rotation path of the toilet body 40, and the toilet body 40 in a state where the bucket 50 is received by the receiving unit 60. The rotation path is secured. Therefore, the bucket 50 and the accommodating part 62 can be folded without being removed.

As shown in FIG. 11, when the leg part 11 is closed, at least a part of the toilet body part 40 enters the space part 91 below the backrest part 90. Thereby, the thickness of the front-back direction in a folded state can be made as thin as possible. In a state in which the leg body portion 11 is folded, the seat portion 80 in a state of being superimposed on the upper portion of the receiving portion 60 together with the toilet seat 70 can pass under the backrest portion 90. In the present embodiment, as shown in FIG. 11, in a folded state, the seat portion 80 is pressed by the holding portion 75, and the seat portion 80 is overlapped with the toilet seat 70 while the receiving portion 60 receives the bucket 50. The state as it is is maintained. The operation of the holding portion 75 will be described in detail later.

When the portable toilet 10 is folded, the user or the assistant first puts the toilet seat 70 and the seat portion 80 over the receiving portion 60 as shown in FIG. Subsequently, the armrest main body 93 is flipped up and further rotated rearward and downward, so that the armrest main body 93 is turned downward from the horizontal state at the rear position of the toilet main body 40. Next, the user or the like turns one hand to the back of the backrest 90, attaches one hand to the rear surface of the backrest 90, and attaches the other hand to the lower part of the front side wall 61a of the body frame 61, The toilet body 40 is turned upward so that the backrest 90 and the front of the toilet body 40 are brought close to each other. Thereby, while the toilet body part 40 becomes vertical, the leg part 11 is folded in response to the operation | movement. When the portable toilet 10 is folded, the strap 55 is hooked on the protrusion 59, so that the folded state is stably maintained.

When opening the portable toilet 10 in the folded state, the user or caregiver first removes the ring portion 58 of the strap 55 from the protruding portion 59. Next, the toilet body 40 is rotated downward so that the backrest 90 and the front of the body frame 61 are separated from each other. At this time, it is good to assist so that the downward rotation of the toilet body 40 may be performed slowly with the strap 55 attached to the lower part of the front side wall 61c of the body frame 61. After the legs are opened, a state in which the toilet seat 70 and the seat 80 are overlaid on the receiving portion 60 is naturally formed by its own weight. Therefore, it can function as a chair immediately after the legs are opened. Moreover, if the seat part 80 is rotated and retracted backward, it can function as a toilet.

<< Operation of holding part 75 >>
Next, the operation of the holding unit 75 will be described in detail. FIG. 13 is a diagram illustrating a transition of the position of the holding unit 75 with respect to the seat 80 when the portable toilet 10 is folded. In FIG. 13, the portable toilet 10 is viewed from the right side. In FIG. 13, (a) shows an open leg state, (b) and (c) show states in the middle from the open leg state to the closed leg state, and (d) shows a closed leg state, respectively.

As the leg portion 11 changes from the open leg state to the closed leg state, the holding portion 75 moves from a non-holding position below the seat portion 80 to a position above the seat surface of the seat portion 80. Move to the holding position. Specifically, as illustrated in FIG. 13A, the rotating body 77 is positioned below the seating surface of the seat 80 due to the weight of the holding portion 75 in the open leg state. This position is a non-holding position of the holding portion 75.

In this process, the toilet body 40 is pivoted upward, and in the process of changing the posture of the leg part 11 from the open leg state to the closed leg state, as shown in FIG. Rotating body 77 in contact with the rear end of 80 and riding on the seat as it is from the rear of seat 80, and thereafter, as shown in FIG. Moves along the seating surface of the seat 80 while rotating forward while remaining in contact with the seating surface. Thereby, the state which the seat part 80 covered the upper part of the toilet seat 70 is hold | maintained during operation | movement of folding.

When the toilet body 40 is in a vertically oriented state and is in a folded state, the rotating body 77 remains in contact with the seating surface, more specifically, with the rotating body 77 holding the seating surface from above, It remains in a predetermined position above the seating surface of the portion 80 (see FIG. 13D). In the present embodiment, the holding position of the holding portion 75 is the position where the rotating body 77 is located at the intermediate position of the seat portion 80, more specifically, the front portion 82 side. By restraining from above the seating surface by the holding portion 75, the seat portion 80 is prevented from expanding rearward after folding, and the bucket 50, the tray 63, and the accommodating portion 62 are restrained from jumping out rearward. The rotating body 77 corresponds to a contact portion that contacts the seating surface of the seat portion 80 in a closed leg state.

≪Configuration of the lower end of the leg part 11≫
Next, the structure of the lower end part of the leg part 11 will be described in detail. FIG. 14 is a right side view of the lower end portion of the leg portion 11 in the open leg state, and FIG. 15 is a perspective view of the leg rubber 30. As shown in FIG. 14, on the lower surfaces of the front leg portion 12 and the rear leg portion 13, there are provided a first surface 29a and a second surface 29b that forms an angle intersecting the first surface 29a. The first surface 29a and the second surface 29b are disposed adjacent to each other in the front-rear direction. The second surface 29b is disposed on the outer side in the front-rear direction with respect to the first surface 29a.

The leg rubber 30 is attached to the lower surfaces of the first surface 29a and the second surface 29b. The leg rubber 30 is provided across the first surface 29 a and the second surface 29 b with respect to the lower surfaces of the front leg portion 12 and the rear leg portion 13. In the present embodiment, the leg rubber 30 is attached to the lower surfaces of the

height adjusting portions

24 and 26 of the front leg portion 12 and the rear leg portion 13.

The leg rubber 30 is a long plate-like rubber member. One plate surface of the leg rubber 30 is a contact surface 31 that is in contact with the first surface 29a and the second surface 29b of each leg of the leg portion 11, and the other plate surface is the contact surface 31. The ground surface 39 is grounded to the floor surface in contact with the first surface 29a and the second surface 29b. The ground contact surface 39 has a first contact surface 39a parallel to the first surface 29a and a second contact parallel to the second surface 29b in a state where the leg rubber 30 is attached to the lower surfaces of the front leg portion 12 and the rear leg portion 13. And ground 39b. The first ground surface 39a is grounded to the floor surface when the first surface 29a of the leg portion 11 is disposed to face the floor surface, and the second ground surface 39b is disposed to face the floor surface to the second surface 29b. When touching, it is grounded to the floor. The first ground plane 39a and the second ground plane 39b are disposed adjacent to each other, and the first ground plane 39a has a larger area than the second ground plane 39b.

The first grounding surface 39a has a protrusion 32 protruding from the first grounding surface 39a at the end on the second grounding surface 39b side. In the present embodiment, as shown in FIG. 15, the protrusion 32 extends along the length direction of the boundary between the first ground surface 39 a and the second ground surface 39 b at the end on the second ground surface 39 side. It is a ridge. The protruding portion extends over the entire region in the length direction of the boundary between the first ground surface 39a and the second ground surface 39b.

As shown in FIG. 15, a groove 33 extending in the length direction of the boundary is formed on the ground surface 39 of the leg rubber 30 at the boundary between the first ground surface 39a and the second ground surface 39b. The groove 33 is formed over the entire length direction of the boundary between the first ground surface 39a and the second ground surface 39b, and the protrusion 32 is disposed on the first ground surface 39a adjacent to the groove 33. Has been. The leg rubber 30 is attached to the first surface 29a and the second surface 29b by being bent at the groove 33 so that the contact surface 31 is inside. Since the groove 33 is formed on the plate surface, the leg rubber 30 can be easily bent at the boundary between the first ground surface 39a and the second ground surface 39b and attached to the first surface 29a and the second surface 29b. It has become.

A through hole 34 penetrating in the thickness direction is formed in the ground surface 39. In the present embodiment, one through hole 34 is provided on each of the first ground surface 39a and the second ground surface 39b. Projections (not shown) projecting downward are formed on the first surface 29 a and the second surface 29 b of the leg 11. The height of the protrusion is smaller than the thickness of the main body 35 of the leg rubber 30. The leg rubber 30 can be attached to and detached from the lower surfaces of the front leg portion 12 and the rear leg portion 13 by fitting the through holes 34 of the leg rubber 30 into the protruding portions.

≪Operation of leg rubber 30≫
Next, an operation when the leg rubber 30 is attached to each leg of the leg body portion 11 will be described.

As shown in FIG. 14, the portable toilet 10 is provided with a protrusion 32 on the outer edge in the front-rear direction of the first ground surface 39a. Therefore, when the portable toilet 10 is not grounded and viewed sideways in an open leg state, the lower end of the outer edge 38A in the front-rear direction on the first ground surface 39a is lower than the lower end of the inner edge 38B. positioned. More specifically, in both the front and rear legs of the leg portion 11, the lower end of the outer edge 38A in the front-rear direction on the first ground surface 39a is positioned below the lower end of the inner edge 38B. 14 represents the height position of the lower end of the outer edge portion 38A.

As described above, when the lower end of the outer edge portion 38A is positioned below the lower end of the inner edge portion 38B, the outer edge portion in the front-rear direction of the first ground surface 39a in the opened state. 38A is easily grounded. Further, since the outer edge 38A in the front-rear direction of the first grounding surface 39a is easily grounded, the distance between the grounded portions in the front-rear direction can be made as long as possible. Therefore, the center of gravity of the portable toilet 10 can be set at a low position, which contributes to improvement of stability in the open leg state. Further, even when the rattling of the leg occurs due to product variation or the like, the outer edge 38A in the front-rear direction of the first ground surface 39a can be preferentially grounded. As a result, stability can be improved while suppressing rattling in the open leg state.

FIG. 16 is an enlarged side view showing the transition of the ground contact state of the lower surface of the leg portion 11 when the posture is changed from the closed leg state to the open leg state. Although the rear leg portion 13 is described here, the same applies to the front leg portion 12. In FIG. 16, (a) shows a closed leg state, (b) shows a state during the posture change from the closed leg state to the open leg state, and (c) shows a closed leg state.

In the closed leg state, as shown in FIG. 16A, the second ground surface 39b is in a state of being grounded to the floor surface G. When the leg state is changed from this state, the grounding state with the second grounding surface 39b is changed to the grounding state with the first grounding surface 39a. In the portable toilet 10, since the protrusion 32 is provided at the outer edge 38A in the front-rear direction of the first ground surface 39a, when the first ground surface 39a changes from the non-ground state to the ground state, the first ground surface The outer edge portion 38A of 39a is likely to be grounded first (see FIG. 16B). In the state where the user is seated in the open leg state, as shown in FIG. 16C, the protrusion 32 is crushed by the elastic deformation of the rubber and the first ground contact surface 39a is received by the surface. Stabilize. However, the protrusion 32 may be crushed by the dead weight of the portable toilet 10, and the first ground contact surface 39a may be received by the surface.

According to the configuration of the present embodiment described in detail above, the following excellent effects can be obtained.

Since the portable toilet 10 has a rotation path of the toilet body 40 in a state where the bucket 50 is received by the receiving portion 60, the portable toilet 10 can be folded with the bucket 50. In addition, since the front leg portion 12 and the rear leg portion 13 can stand on their own in the closed leg state, they can stably stand on their own in the folded state even with the bucket 50 and the accommodating portion 62 provided.

The portable toilet 10 is provided with a main body support portion 67 that supports the toilet main body 40 so that the toilet main body 40 is kept in the horizontal state in the open leg state. As a result, when the toilet body 40 is made to be pivotable while being in an open leg state, the sideways state of the toilet body 40 can be stably maintained. Further, even when a force is applied to the toilet main body 40 from above by the user when using the toilet, the horizontal posture of the toilet main body 40 is stably maintained by being supported from below by the main body support 67. be able to. In particular, in the present embodiment, since the main body support portion 67 is provided on the inner plate surface of the front leg portion 12, the main body frame 61 can be supported at a more forward position. Thereby, in the open leg state, the toilet body 40 can be kept in a more stable sideways state. In addition, since the main body support portion 67 is provided on the inner plate surface of the front leg portion 12, the main body support portion 67 is hardly conspicuous from the outside, and the appearance is also good.

The connecting arm 28 and the leg abutting portion 18 are provided as a restricting portion for restricting the lower portion of the front leg portion 12 and the lower portion of the rear leg portion 13 from being further separated in a predetermined open state. By having such a restricting portion, the maximum leg position of the leg portion 11 can be determined. Thereby, even when a user is seated and a force is applied to the toilet body 40, the portable toilet 10 can be stably maintained in a predetermined open leg state.

In particular, the leg contact portion 18 is provided on the inner plate surface of the rear leg portion 13, and the lower surface of the front leg portion 12 and the rear leg portion 13 are brought into contact with the rear surface of the front leg portion 12 against the contact surface 18 a. Since the lower portion is regulated so as not to be further separated, it is possible to more reliably regulate the further opening from a predetermined open leg state, which is preferable from the viewpoint of safety. Moreover, since it fixed to the plate | board surface of the rear leg part 13, it is excellent also in stability and durability. Further, since the leg abutting portion 18 is provided on the inner plate surface of the rear leg portion 13, it is difficult to stand out from the outside and the appearance is good.

At the time of folding, at least a part of the toilet body 40 enters the space 91 below the backrest 90. In this case, in the folded state, since at least a part of the toilet body 40 enters the space 91 below the backrest 90, the thickness in the front-rear direction can be made as thin as possible in the folded state. Thereby, it can be made more compact in the folded state.

The portable toilet 10 is provided with a holding part 75 that holds the receiving part 60 in a closed leg state in which the bucket 50 is received. Thereby, it can suppress that the bucket 50 jumps back when it is set as a folding state. Further, since the holding portion 75 moves from the non-holding position to the holding position as the leg is closed, the above function of the holding portion 75 can be exhibited in conjunction with the folding operation. Thereby, even if the user does not bother to operate the holding portion 75, the bucket 50 can be prevented from jumping backward in the folded state.

Since the seat 80 is provided in the portable toilet 10, it can function not only as a toilet but also as a chair. Moreover, if the seat part 80 is rotated and retracted to the rear, it can immediately function as a toilet. Further, since the holding portion 75 holds the seat portion 80 in a state of being overlapped with the toilet seat 70 in the closed leg state, the cleanliness can be improved in the folded state without exposing the toilet seat 70 and the opening 53 of the bucket 50. it can.

The holding portion 75 has a rotating body 77 as a contact portion that contacts at least the seating surface of the seating portion 80 in the closed leg state, and the rotating body 77 moves along the seating surface in the process of changing the posture from the open leg state to the closed leg state. By moving, the seat 80 is held in a state of being overlapped with the toilet seat 70. In this case, the state in which the seat 80 covers the toilet seat 70 can be maintained not only after the folding state but also during the operation until the folding state. Thus, the toilet seat 70 and the opening 53 of the bucket 50 can be covered with the seat portion 80 from time to time except when using the toilet, and a clean state can be maintained.

In addition, since the rotating body 77 is provided in the holding portion 75 and the rotating body 77 functions as a contact portion, the contact portion moves smoothly along the seating surface in the process of changing the posture from the open leg state to the closed leg state. Can do. Thereby, the state in which the holding portion 75 holds the posture of the seat portion 80 can be formed smoothly.

A process in which the holding part 75 moves from the non-holding state to the holding state so that the holding part 75 includes the linear body 76 and the rotating body 77 and restricts the rotation of the linear body 76 within a predetermined rotation range. In the initial stage in which the rotation of the linear member 76 is permitted, the rotating member 77 can smoothly ride on the seating surface, and after the rotating member 77 rides on the seating surface, By restricting the rotation of 76, the rotating body 77 can maintain a state in which the seat surface of the seat portion 80 is suppressed from above.

A connecting portion 23 for connecting each front leg portion 12 is provided above the lower end of the front leg portion 12, and the front surface 23a of the plate surface of the connecting portion 23 faces obliquely downward in the open leg state. With such a configuration, it is possible to secure a wider space in the lower portion of the front leg portion 12 while increasing the strength of the leg portion 11. Thereby, it is possible to make it easier for a toilet user or a caregiver to step in the backward direction from the front of the toilet.

In the open leg state, the front surface 23a of the connecting member 23 faces diagonally downward, so that the rear surface 23b of the connecting member 23 faces obliquely upward. It is possible to contribute to securing an installation area and making it easier to secure a rotation path of the toilet body 40.

Since the side wall portion 62b of the housing portion 62 is inclined inward toward the bottom portion 62a, the toilet body portion 40 is less likely to contact the connecting portion 23 when the toilet body portion 40 is rotated upward. Therefore, it is possible to contribute to securing the rotation path of the toilet body 40.

The leg portion 11 has, at the lower end of each leg, a first grounding surface 39a that is a grounding surface in the open leg state and a second grounding surface 39b that is a grounding surface in the closed leg state. In this case, when the toilet is used, the first ground surface 39a of each leg is grounded to the floor surface, so that stability when the user puts weight on the toilet body 40 can be ensured. Further, in the folded state, the second grounding surface 39b of each leg is grounded to the floor surface, so that the legs can be stably and independently supported by the front, rear, left and right legs. Therefore, it can be set as a portable toilet with high stability in both the open leg state and the closed leg state.

When viewed from the side in the open leg state, the lower end of the outer edge 38A in the front-rear direction on the first ground contact surface 39a is located below the lower end of the inner edge 38B. In this case, in the open leg state, it is possible to form a state in which at least the outer edge portion 38A of the first ground surface 39a is grounded, and the center of gravity can be set at a lower position. Thereby, the stability in an open leg state is securable.

In particular, with respect to the opening and closing directions of the front leg portion 12 and the rear leg portion 13, the lower end of the outer edge portion of the first ground contact surface 39a is positioned below the lower end of the inner edge portion, so that the movement of the leg is This is preferable in terms of ensuring stability in the allowed direction.

The rattling of the leg portion 11 due to product variations or the like tends to increase by widening the first ground contact surface 39a. In this regard, by setting the lower end of the outer edge 38A in the front-rear direction on the first ground contact surface 39a to be positioned below the lower end of the inner edge 38B, the center of gravity can be set at a lower position. Thereby, shakiness of the leg part 11 can be suppressed.

Since the second ground surface 39b is provided on the outer side in the front-rear direction with respect to the first ground surface 39a, the second ground surface 39b can be made to stand by itself more stably when the leg is closed. In addition, the first ground contact surface 39a is opened because the lower end of the outer edge 38A is located below the lower end of the inner edge 38B in a side view when the leg 11 is not grounded. At the time of the leg, the center of gravity can be set at a low position, and the stability when the user is seated can be ensured. That is, it is possible to achieve both stability when the legs are opened and stability when the legs are closed.

The leg portion 11 has a plate-like leg rubber 30 at the lower end of each leg, and a first grounding surface 39 a and a second grounding surface 39 b are formed by the lower surface of the leg rubber 30. By using the leg rubber 30 which is a separate member, it is possible to easily form a state in which the lower end of the outer edge 38A in the front-rear direction on the first ground surface 39a is positioned below the lower end of the inner edge 38B. . Moreover, by using a rubber member, it is possible to have both a function of ensuring stability and a function of preventing slipping.

The leg rubber 30 has a protrusion 32 protruding downward on the outer edge 38A in the front-rear direction of the first ground contact surface 39a. By providing the protrusion 32 formed of rubber on the outer edge 38A in the front-rear direction of the first ground surface 39a, the outer edge 38A of the first ground surface 39a is first grounded to the floor surface when the legs are opened. It can be made easier. Thereby, stability can be ensured from the earliest possible stage of the process from the closed leg state to the open leg state. In addition, in a state where the legs are opened and a force is applied to the first grounding surface 39a from above, the rubber is elastically deformed. Therefore, even when the protrusions 32 are provided, the toilet body 40 while suppressing the occurrence of rattling. Can be supported by the leg portion 11.

When the portable toilet 10 is folded and opened, the ground contact surface 39 is easily rubbed or brought into contact with the floor surface, and the protrusion 32 may be reduced as time passes. In this respect, since the protrusion 32 is a protrusion extending in the left-right direction at the outer edge 38A in the front-rear direction of the first grounding surface 39a, it is excellent in terms of strength and durability. Therefore, the function of ensuring stability in the open leg state by the leg rubber 30 can be maintained for a long time.

Since the groove 33 is provided at the boundary between the first ground surface 39a and the second ground surface 39b in the lower surface of the leg rubber 30, the leg rubber 30 is easily bent at the boundary position between the first ground surface 39a and the second ground surface 39b. The front leg portion 12 and the rear leg portion 13 can be easily attached along the shape of the lower surface.
