DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a simple chair type toilet bowl,
In particular, the present invention relates to a simple chair-type toilet that is suitable for use by the elderly and the physically handicapped.

[0002]

2. Description of the Related Art Elderly or physically handicapped persons who have weak legs are difficult to move to a toilet, and therefore, a portable simple toilet is sometimes used for stool.

[0003] As a conventional simple toilet, there is a toilet in which the appearance is formed in a chair shape. In this toilet, a waste container is detachably attached to a seating portion, and an upper end opening portion of the waste container is opened and closed. It has a lid that has both a function as a seat and a function as a seat plate of a chair. In addition, a backrest stands upright behind the disposing portion of the waste container.

In this case, when the lid is opened, the waste container becomes usable and can be used, and the lid for closing the upper end opening of the waste container can also be used as a seat plate of a chair. So you can sit down and take a rest. Further, since the appearance is formed in a chair shape, it does not impair the design feeling in the room by exhibiting an interior decoration function as compared with a toilet having a clear appearance that it is apparently a toilet.

[0005]

However, in the above-mentioned conventional simple toilet bowl, although it is used by elderly people with weak legs and the like, it does not have a function for assisting the sitting or standing operation. There was a problem that physical burden could not be reduced.

[0006] The present invention has been made in view of the above points, and an object of the present invention is to make it possible to easily perform a sitting operation and a standing operation. * 1

[0007]

The technical means of the present invention for solving the above-mentioned problems is as follows: a frame for mounting a waste container having an open upper end in a dropped state, a frame attached to the frame, and A vertically rotatable lid that closes the upper end opening of the waste container, and the lid and the toilet seat portion of the waste container below the lid are located between a seating position suitable for a user to sit and an upward position above the toilet seat. And an operation switch for turning on / off a drive source of the elevating mechanism so as to move the frame body integrally so as to move integrally.

According to the above technical means, when the driving source is turned on by operating the operation switch, the lifting / lowering mechanism is actuated by the driving source, whereby the waste container and the lid for closing the waste container are moved together with the frame. Go up and down. That is, the toilet seat or the lid of the waste container integrally reciprocates between a seating position suitable for seating and a rising position above the seating position.

[0009] Therefore, after the user deposits the buttocks on the toilet seat or the lid at the elevated position, the toilet seat or the lid of the waste container can be lowered to the seating position below the user. Conversely, when the toilet seat or the lid of the waste container is raised from the sitting position to the raised position, the user's buttocks are raised and the position of the center of gravity of the body is raised.

[0010]

The present invention has the following specific effects. After the user deposits the buttocks on the toilet seat or the lid of the waste container at the ascending position, the toilet seat or the lid can be lowered to the seating position below the user, so that the seating operation can be easily performed. On the other hand, when the user stands up, the toilet seat and the lid of the waste container rise and the buttocks of the user rise, so that the standing operation can be easily performed.

"
Since the frame is moved up and down using the four-bar link mechanism as each unit elevating mechanism, the movement locus of the frame is uniquely determined. Therefore, the movement trajectory of the toilet seat and the lid of the waste container attached to the frame is stabilized.

* 3. In the above two items, in the above two items, "the pair of front and rear links is
When the front link is shorter than the rear link, the upper end of the rear link rises faster than the upper end of the front link when raising the frame, so the frame with the waste container etc. tilts forward. State, and the user can stand and sit more easily.

* 4. In the above item 2 or 3, in which the output portion of the driving source is connected to a connecting bar connecting the pair of rear links, the output of the driving source is It is distributed to a pair of links on the rear side via the connecting bar. Therefore, unlike the case where the output portion of the drive source is directly connected to only one of the pair of rear links, no torsional force acts on the frame, and the frame is less likely to be deformed. In particular, when the frame including the waste container and the like is inclined forward when the frame body including the waste container and the like is lifted, the rear part of the seated person's buttocks at the output part of the driving source is obliquely upward from behind. As a result, the frame body is smoothly inclined to the forwardly inclined posture as compared with the case where the front part of the frame body is pushed up.

* 5. In the above-described items 1 to 4, in which "the means for holding the lid body in the open position" is provided, the lid body in the open state falls down carelessly. Can be avoided. The following can be employed as specific means for holding the lid in the open position. That is, "the means for holding the lid in the open position is a tension spring provided between the lid and the frame, and the tension spring is provided at the upper end opening of the waste container. The most extended state when it is in the middle position between the closed position in which the cover is closed and the open position in which it is opened '' and `` an engagement pin projecting from a side portion near the pivot point of the lid, A corrugated leaf spring (provided on the frame) having a concave portion into which the engaging pin is forcibly fitted when the body is released ”(see FIG. 5).

Item 6 In the above item 1 to item 5, the item "having an elbow rest continuously provided on both sides of the frame body in the lateral direction of the toilet" is characterized in that the elbow rest is a waste container or a lid thereof. Since the user moves up and down with the body, the user can stand and sit with the elbow resting on the elbow rest, and the movement can be stabilized.

Item 7 In the above item 1 to item 6, the item "having a backrest connected to the rear end of the frame" has a backrest connected to the frame on which the waste container is mounted. Since it is provided, the back of the user who stands and sits on his back can stabilize the standing and sitting motion.
