DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chair type that can be used safely, easily, and cleanly by elderly people, people with weak legs, and people with physical disabilities without the help of a caregiver. It concerns a simple toilet.

[0002]

2. Description of the Related Art Chair-type simple toilets developed for elderly people, people with weak legs, and people with physical disabilities are becoming widespread in various facilities, hospitals, and general households.

A conventional simple toilet of this type is shown in FIG.
As shown in FIG. 1, a bucket-type toilet (not shown) is attached to a seat-type toilet body 11 under an openable / closable toilet seat 12 hinged to a seat surface portion thereof, and a hinge is provided above the toilet seat 12. An opening / closing seat pad 13 is provided, and an armrest 14 is attached to both sides of the toilet seat 12. When using the toilet, the sitting pad 13 is raised as shown in the figure and overlaps with the backrest. To be overlaid on the toilet seat 12.

However, when the simple toilet having such a structure is used as a chair, the sitting pad 13 is overlapped on the upper surface of the toilet seat 12, so that the surface of the toilet seat 12 is contaminated with dirt.
3 is attached to the back of the toilet seat, and the back of the sitting pad is used as a backrest when using the toilet. Therefore, the surface of the toilet seat 12 must be wiped off at all times. Had the disadvantage of being discomforted.

[0005] In order to solve the above-mentioned difficulties, various chair-type toilets have been proposed in which the contact surface of the sitting pad with the toilet seat 12 does not hit the back. For example, the chair-type simple toilet shown in FIG.
1 is a structure in which a toilet seat 22 is attached to a seat surface portion, and detachable armrests 23 are attached to both sides of the toilet seat 22. A central portion on the back side is rotatably attached to a concave support pipe 25, and the seat pad 24 is used when the toilet is used.
Is slid to the back side of the toilet main body as shown in the drawing, and is slanted forwardly to the toilet seat 22 side, and is drooped.
When used as a chair, the sitting pad 24 hanging down from the rear side is pulled up, pulled toward the user, and placed on the toilet seat 22. Therefore, in the case of this simple toilet, even if dirt on the surface of the toilet seat 22 adheres to the back surface of the sitting pad 24, the back surface of the sitting pad 24 is bent forward toward the toilet seat 22, so The above problem is solved because only the side edge of the sitting pad 24 hits and the dirty surface does not contact the back of the toilet user.

The chair type toilet shown in FIG. 7 uses a seat pad which can be folded in two as a means for preventing the contact surface of the sitting pad with the toilet seat from hitting the back. In a chair-type toilet having detachable armrests 33 attached to both sides of a toilet seat 32 attached to a seating surface of a main body 31, a sitting pad 34 that can be folded in half from the center is hinged to the end of the toilet seat 32. When the toilet is used, the sitting pad 34 is folded inward as shown in the figure to stand on the backrest side of the toilet body, and when used as a chair, the toilet pad is used when the toilet is used. The seat pad 34 folded inward is opened and placed on the toilet seat 32. Therefore, in the case of this simple toilet, the toilet seat 32
Even if the surface dirt adheres to the back surface of the sitting pad 34, the back surface that becomes the dirty surface by folding the sitting pad 34 inward faces inward, and the upper surface of the sitting pad 34 becomes the backrest surface. Therefore, the above problem is solved.

[0007]

However, the above-mentioned simple toilet has the following drawbacks. First, when using the toilet, the sitting pad 24 is pushed to the rear side of the toilet main body to be tilted forward to the toilet seat 22 side so that the sitting pad 24 is suspended downward. Since the sitting pad 24 hanging down to the side must be pulled up and pulled toward the user, the sitting pad 24 is pulled up alone and set on the toilet seat 22, especially for the elderly or the handicapped. It is difficult to use the toilet, and the upper part of the sitting pad 24, which is inclined forward and bent down to the back side of the toilet body when using the toilet, projects toward the toilet seat side from the backrest of the chair. It is undesired because it gets in the way. In addition, in the case of the simple toilet shown in FIG. 7 using the folding pad 34, not only is the cost of the sitting pad high, but also
Because it is split from the center, it is not comfortable to sit on,
The sitting pad in a state of being folded into two may inadvertently fall to the toilet seat side, which is not preferable. Furthermore, all of the above-mentioned conventional simple toilets have the disadvantage that the toilet seat and the sitting pad are of a fixed type and cannot be easily removed, so that they cannot be easily replaced and cleaning is inconvenient.

The present invention has been improved in order to solve such a conventional problem. When a toilet is used, one sitting pad can be exposed to the rear side of the toilet main body, and the strength of the arm can be improved. It aims to provide a chair-type simple toilet that can be easily removed by both elderly and handicapped people who cannot use it, and that both the sitting pad and the toilet seat can be easily removed. is there.
