The toilet seat has a pair of detachable handles that also serve as armrests on both side portions of the toilet seat, and a chair-type simple toilet that has an openable and closable seat pad that is placed on the toilet seat. It consists of a pair of left and right ground members and a vertical plate erected on the upper surface of the ground member, and the seat frame is attached to the legs so that the height can be adjusted by a screw pin insertion type height adjustment mechanism, The openable toilet seat and the openable seat pad are detachably attached so as to overlap each other on the back side of the seat frame, and the pair of left and right removable handles that also serve as the armrests are a long handle portion and A vertical part bent at a right angle from the end of the handle part and parallel to the long handle part from the vertical part It is composed of a single member having a short handle portion bent at right angles, and is detachably attached to the side surfaces of the seat frame and the backrest portion so that the height position can be changed. A chair-type simple toilet having a structure that can be attached with the short handle portion on the lower side, the short handle portion on the upper side, and the long handle portion on the lower side (see Patent Document 2).
(3) The seat frame, which is supported by the leg so that the height can be adjusted, is integrated with a backrest, and both sides of the toilet seat are equipped with flip-up or detachable armrests and placed on the toilet seat. A chair-type simple toilet having an openable and closable sitting pad, wherein the leg is composed of a pair of left and right grounding members parallel to each other and a wide vertical plate standing on the upper surface of the grounding member. The seat frame is attached so that the height can be adjusted by a screw pin insertion type height adjustment mechanism, and the openable and closable toilet seat and the openable and closable seat pad are detachable so as to overlap each other on the back side of the seat frame. In the chair-type simple toilet attached to the chair, the seat frame body includes left and right side plates and a rear plate, a front plate inclined inward, and a curved plate mounted so as to be slidable vertically along the lower inner surface of the front plate. The backrest has a backrest material between a pair of left and right struts. The backrest depth is adjustable so that it can be moved in the front-rear direction, and the opening / closing operation force of the opening / closing seat pad is reduced, and the opening / closing operation force of the opening / closing seat pad is reduced. The elastic support means includes a spring cylinder, the elastic means includes a kick spring, and the spring cylinder elastically supports the openable toilet seat. A chair-type toilet that is attached to a seat frame and is mounted on a pivoting portion of the seat pad so that the kick spring urges the opening / closing seat pad to rotate in a certain direction (Patent Document 3).

  However, the conventional general chair-type toilets including the above-described three types of chair-type toilets, except for the portable toilets with a very simple structure, cannot be folded in all chair-type toilets. Therefore, it is not only inconvenient to carry, but also cannot be stored and stored easily in a narrow and limited space. The fact is that we are struggling with.

In view of such a situation, the present inventors set the chair-type simple toilet body in the front-rear direction without impairing the function as a conventional general chair-type simple toilet including the above three types of chair-type simple toilets. A folding chair-type simple toilet that can be easily folded has been proposed (Patent Document 4).
This foldable chair-type toilet has a pair of left and right backrest / rear pipes and a pair of left and right front pipes, and has a toilet seat receiver horizontally disposed between the backrest / rear pipe and the front pipe. The front part of the toilet seat receiver is pivotably attached to the front and back, and the rear part of the toilet seat receiver is pivotally attached to the backrest and rear pipe so that it can be turned up and down. The toilet seat receiver and front pipe rotate up and down through a pair of left and right folding connecting rods, and the toilet body is folded back and forth, and the toilet body is folded at the backrest / rear pipe and toilet seat receiver. With a locking mechanism in the open state, the toilet body can be folded back and forth with a simple operation Because it is a structure that can be carried, it is not only convenient to carry, but can also be easily stored and stored in a narrow and limited space. Is easy to secure, and has a locking mechanism to prevent the toilet body from being opened or folded inadvertently. It has an excellent feature that is improved.
However, in this folding chair-type simple toilet, when the toilet body is opened from the folded state, when the lock mechanism in the opened state is released, the opening operation of the toilet body is instantaneously performed by the weight of the toilet body. Therefore, when the front pipe is suddenly opened, it is necessary to be careful not to cause injury due to contact with the toilet bowl or armrest, etc. In some cases, the toilet body is relatively heavy, which causes a burden on the handle and is not preferable.
