JP 2001-190448 A

By the way, it is troublesome to attach and detach each time the sheet body is used as a toilet in the type in which the sheet body is once removed and used when using such a portable toilet. Further, when the removed sheet body is placed on the floor without a place for storage, it is necessary to squat once to take it up after the stool, and such an operation may be difficult for the sick or elderly. Therefore, there is an idea that the sheet body is folded in two without being removed and retracted to the rear position of the backrest. However, such an evacuation type has the following problems.
1) When the sheet body is folded in two without being removed and retracted to the back position of the backrest, the space below the backrest 50 is moved backward through the sheet body 51 as shown in FIG. There is a need. As shown in FIG. 9, there is no problem if the position of the backrest 50 is increased and a sufficient space can be formed below the backrest 50 position. However, in reality, this type of portable toilet for a chair is set so that the back of the human body of a general body abuts against the backrest at a lower position than the shoulder ribs. This is intended to hold a person with no physical strength, such as an elderly person or a sick person, and to prevent the thin part of the skin above the shoulder rib from touching the backrest as much as possible. Therefore, in the portable toilet for chairs, the space below the backrest is narrow. In addition, this type of chair-to-chair portable toilet has a relatively large seat body for attaching a toilet seat and a bucket, and accordingly, the front and rear length of the seat body is designed to be long. That is, in addition to the narrow space below the backrest, it was actually impossible to fold and pass the space below the backrest coupled with the long front and back of the seat body.
2) Other accessory equipment (for example, a container, a shower toilet unit, a shower tank, etc.) may be attached to the back of the backrest. If there is such an attached facility, even if the sheet body can be folded, the attached facility becomes an obstacle and the sheet body cannot be retracted backward.
The present invention has been made paying attention to such problems existing in the prior art. An object of the present invention is to provide a portable toilet for a chair that includes a seat body that can be folded even if the space below the backrest is limited and does not protrude greatly before and after the backrest.

  In order to achieve the above object, according to the first aspect of the present invention, a seat having an opening, a plurality of legs that support the seat, and a toilet seat disposed in the opening of the seat, , A seat mounted on the upper surface of the same seat covering the toilet seat, a pair of left and right backrests erected on the back of the seat, and supported by the both struts and below the support position In a portable toilet for a chair having a backrest that forms a space communicating in a direction, the seat body is divided into two in the front-rear direction to form a front divided body and a rear divided body, and the two divided bodies are folded upward by a hinge member. A pivot arm having a pivot center disposed at a position spaced apart from the rear segment is attached to the rear end side of the rear segment, and the rear portion is mounted on the seat with the pivot arm. The divided body is pivotally supported so that it is behind the rear divided body. A storage space having a shelf that is stepped down with respect to the upper surface of the seat portion is formed at a position below the backrest, and the rear divided body is erected while rotating backward with the pivot arm as a base point. The gist is that the rear end face of the rear divided body is brought into contact with the shelf of the storage space, and the rear divided body is arranged between the backrest and the shelf.

  In such a configuration, when the rear divided body is erected while rotating backward with the pivot arm as a base point, the pivot center of the pivot arm is located at a position separated from the rear divided body. The body also turns from the turning center of the turning arm along a trajectory corresponding to the length and extending direction of the arm. In the present invention, the shelf is formed at the rear of the rear divided body and is formed one step below the backrest, and the rotating arm is rotated to such a position that the rear end surface of the rear divided body can be erected at this position. A moving center is arranged, and further, it is configured to have a predetermined extension length and shape. The rear divided body moves rearward along with the start-up operation, and at the same time, moves obliquely toward the shelf portion that is lowered by one step. Therefore, even if the position of the backrest is low, the rear divided body can be stored in the storage space. Further, since the storage space is arranged just below the backrest, the folded sheet body does not protrude from the backrest to the rear side. The rear divided body is stored in the storage space in a state of being sandwiched between the backrest and the shelf. At the same time, the front division follows the standing of the rear division and is arranged back to back.

In addition, in the invention of claim 2, in addition to the configuration of the invention of claim 1, the rear divided body does not tilt further when the rear end face of the rear divided body is brought into contact with the shelf. The gist is to do so.
As a result, the rear divided body stored in the storage space does not fall to the rear side of the backrest, so that, for example, even if other accessory equipment (for example, a shower tank) is disposed behind the backrest, Absent. Moreover, since it does not protrude beyond the backrest, it is preferable in terms of appearance.
Further, in the invention of claim 3, in addition to the configuration of the invention of claim 1 or 2, it is the same as when the front divided body is erected back to back with the rear divided body in a state where the rear divided body is stored. The gist of the invention is that the thicknesses of the two divided bodies substantially coincide with the front-rear width of the backrest. According to a fourth aspect of the invention, in addition to the configuration of the third aspect of the invention, the upper surface of the front divided body is arranged substantially flush with the front surface of the backrest in the standing state. The gist.
In other words, since the thickness of the two split bodies in the folded state substantially matches the width of the back and forth of the backrest and does not protrude greatly, the rear side will not abut against this even if there are other accessory equipment. In this case, it does not disturb the user who leans against the backrest. The upper surface of the front divided body is preferably disposed substantially flush with the front surface of the backrest in the standing state.
Further, in the invention of claim 5, in addition to the structure of the invention of any one of claims 1 to 4, the gist is that a holding means is provided so that the rear divided body is held in an upright state. And
When the holding means for maintaining the standing state of the rear divided body is provided in this way, the rear divided body does not fall forward and the usability is good. Specifically, it is preferable that the left and right widths of the rear divided body be the same as or slightly wider than the interval between the backrest struts so as to be press-fitted into the backrest struts and sandwiched. Alternatively, it is preferable that the front and rear widths of the rear divided body be the same as or slightly wider than the interval between the backrest and the shelf and press-fit into the backrest and the shelf to be sandwiched.

  In the inventions of the above-mentioned claims, it is possible to guide the folded sheet body downward in the backrest even if the position of the backrest is low in the portable toilet for chair and chair, which is subject to restrictions on the position of the backrest for the purpose of use. Since the storage space is formed, the folded sheet body can be stored without protruding back and forth.

An operation when the portable toilet 1 having such a configuration is used will be described.
When the portable toilet 1 is used as a chair, it is used in a state where the toilet seat 8 is covered by the sheet body 27 as shown in FIG. On the other hand, when used as a toilet, it is necessary to retract and store the sheet body 27 in the storage space 25 from the state of FIG. In that case, the entire sheet body 27 is pushed backward while holding the handle 29 and pulling the sheet body 27 upward. Then, with the movement of the sheet body 27, the rotation arm 30 starts to rotate, and the rear divided body 27b rotates in the standing direction. The front divided body 27a retreats following the retraction of the rear divided body 27b, and the front side hangs down by its own weight with the hinge 28 as the center.
At this time, when looking at the movement of the rear end of the rear divided body 27b, it moves rearward and obliquely downward as indicated by the arrow from the original position indicated by the phantom line in FIG. It will be followed. Then, as shown by phantom lines in FIG. 7, the rear end surface of the rear divided body 27b is in the reinforcing plate 20 and the reinforcing frame 22 in a state where the long portion 30a of the rotating arm 30 is horizontally lying down (rotated approximately 90 degrees). It will contact | abut to the upper surface. At this time, the rear divided body 27 b is erected substantially vertically along the rear leg 3 in the storage space 25.
Here, as shown in FIG. 3, the lateral width of the seat body 27 is configured to be slightly wider than the interval between the two rear legs 3. Therefore, the rear divided body 27b is clamped between the rear leg portions 3 by pushing the front divided body 27a rearward and press-fitted between the rear leg portions 3 so that the rear divided body 27b is firmly held in the storage space 25 without shaking. be able to. Furthermore, the front and rear divided bodies 27a and 27b are properly erected back to back by this pushing operation.
At this time, as shown in FIGS. 6 to 8, the rear divided body 27 b does not tilt backward, so that it does not interfere with the rear shower device 32. Further, since the front and rear divided bodies 27a and 27b fit within the front and rear width of the backrest 16, the front divided body 27a does not protrude from the front of the backrest 16 and push the back of the person using the toilet seat 8. Rather, the user's back is supported at the lower position of the backrest 16.

The present invention has the following specific effects by being configured as in the above embodiment. (1) Since the portable toilet 1 has the backrest 16 at a low position, it is generally difficult to bend the sheet body and pass the lower part thereof. However, in the above embodiment, the upper surfaces of the reinforcing plate 20 and the reinforcing frame 22 are formed at lower levels than the upper surfaces of the side frame 4 and the front frame 6, and the rear divided body 27 b is moved backward by the rotating arm 30. Since it moves obliquely downward, the sheet body 27 can be bent even when the backrest 16 is at a low position. Therefore, it can be stored in the storage space 25 below the backrest 16.
(2) Since the folded sheet body 27 can be stored in the storage space 25 below the backrest 16 without protruding forward and backward, it does not interfere with the shower device 32 arranged at the rear, and the back of the person using the toilet seat 8 There is no problem that would hit.
(3) Since the rear end of the rear divided body 27b is in contact with the upper surfaces of the reinforcing plate 20 and the reinforcing frame 22, the rear divided body 27b does not tilt any further because it serves as a stopper. Accordingly, the rear divided body 27b does not interfere with the shower device 32 disposed on the rear side.
(4) The lateral width of the seat body 27 is configured to be slightly wider than the interval between the two rear legs 3. Therefore, the rear divided body 27b is clamped between the rear leg portions 3 by pushing the front divided body 27a rearward and press-fitted between the rear leg portions 3 so that the rear divided body 27b is firmly held in the storage space 25 without shaking. be able to.

It should be noted that the present invention can be modified and embodied as follows.
In the above embodiment, the shower device 32 may be used without being provided.
