Description

The present invention relates to a simple toilet used mainly indoors.
In particular, it relates to the backrest structure of a simple toilet.

In the field of simple toilets, commonly referred to as portable toilets, they have traditionally been installed beside the bed in a room and used only by caregivers, but in recent years some caregivers have sat on the toilet seat. Since there are people who need a long time to complete the defecation, there is a high need for a chair-type simple toilet with a backrest so as not to get tired.
In addition, there is a demand for the assistant to use a simple chair by providing a cover on the toilet seat.
However, in the case of a chair-type simple toilet, a waste container is installed below the toilet seat as in the case of a normal toilet, and after use, the toilet seat is flipped up backwards, and the tip of the toilet seat is tilted backward. Because it is necessary to take out the trash container while maintaining the body, the depth from the tip of the seat (toilet seat) to the backrest is deeper than that of a general chair, and it has a relatively small physique or a body shape with a rounded back. It was difficult for caregivers to hold the upper body on the backrest and to sit for a long time with peace of mind.
Patent Document 1 discloses a technique for adjusting the backrest depth by laying a backrest material between a pair of left and right struts by means of depth adjustment means, but simply moving the backrest material in the front-rear direction. Yes,
The adjustment range is very limited.

Japanese Patent No. 3973653

  An object of the present invention is to provide a simple toilet that easily leans on a backrest and can easily adjust the depth and angle of the backrest according to the physique and height of the user.

A simple toilet according to the present invention is a chair-type simple toilet having a main body part and a back part pivotally attached to a toilet seat so that the toilet seat can be opened and closed, and the back part comprises a belt arranged between side parts opposed to each other on the left and right. Or having a backrest via the belt.
Here, it is preferable that the tension or length of the belt can be adjusted.
In the present invention, since the backrest is provided via a belt or a belt, it is preferable to provide a reinforcing member on the back, and there is no restriction on the way to provide the reinforcing member, and the reinforcing member may stand upright from the main body. The reinforcing bar may have a substantially U shape in a plan view in which the rear edge portion of the reinforcing bar is located behind the rear edge of the side portion. .
In addition, since the conventional simple toilet bowl has a deeper depth from the tip of the seat to the back than a general chair and cannot be stably seated, the present invention has a belt attached to the side of the toilet so that the toilet seat jumps vertically. The depth to the backrest may be set shallower than in the past by positioning it in front of the raised seat surface.
That the depth is shallower than that of the prior art expresses that the attachment position to the side portion of the belt is located in front of the seat surface where the toilet seat is flipped up vertically.
Therefore, when the length of the belt is adjustable, it means that the seat surface of the toilet seat hits the belt and cannot be raised up vertically when the belt is short or strongly stretched.
Moreover, when the toilet seat mentioned later is slidable in the front-back direction, the positional relationship with the seat surface in the use condition which positions a toilet seat back is said.
The length of the belt is adjustable, for example, when the user is sitting on a chair-type simple toilet, for example, the upper side facing position between the side parts erected from the left and right of the back part of the main body part that becomes the seat part Each has a belt attachment part, and if the belt is stretched strongly, there is little bending backward, the user's backrest position is relatively forward, and conversely, by stretching the belt weakly, An example in which the flexure increases and the backrest position becomes relatively rearward is given.
In addition, by attaching a cover-like backrest member to the belt, the backrest member is positioned forward when the belt length is short, and the backrest member is positioned relatively rearward when the belt length is increased. Can be mentioned.

In the present invention, the belt horizontally disposed between the opposite side portions of the back portion is arranged in a plurality of stages, and the tension of the tension or the length of each of the plurality of stages may be adjustable.
If it does in this way, adjustment of the angle which a user hits will also be attained by changing the tension strength and length between belts of the upper stage and the lower stage.

In the present invention, since the depth from the tip of the seat (toilet seat) to the backrest is set shallow, if the toilet seat is flipped up as it is, the tip of the toilet seat will hit the backrest with the front tilted, and the toilet seat is open as it is May not be held.
In such a case, the toilet seat is preferably slidable in the front-rear direction.
Here, when the toilet seat is slidable in the front-rear direction, when the toilet seat is slid forward and flipped up, it means that the front end of the toilet seat is in contact with the backrest while being tilted rearward, and is kept open.
Therefore, there is no restriction on the sliding structure in the front-rear direction of the toilet seat.

In the simple toilet according to the present invention, since the backrest is provided by a belt or via the belt, the depth from the front end of the seat portion to the backrest can be made shallower than before, and the backrest tends to lean on the backrest.
In addition, since the depth and angle of the user leaning against the backrest can be adjusted, the easy-to-seat toilet that matches the difference in the user's physique, height, or roundness of the back Become.
Since the back portion has the reinforcing member, even if the backrest is made of a belt, there is strength of the back portion, and safety against loosening of the belt or the like is high.
Furthermore, if the toilet seat is slidable in the front-rear direction, even if the distance in the front-rear direction from the sciatic position of the toilet seat to the position of the backrest is set to be short, the backrest is simply raised by moving the toilet seat forward. This keeps the door open and makes it easy to put in and out the trash.
