(Means for Solving the Problems) This invention was made by paying attention to the problems of the conventional technology, and it is a method to solve the problems of the conventional technology. The purpose of the present invention is to solve the above-mentioned problems by forming the support stand in a space where there is no stand to sit on and opening and closing the tip of the support stand.

This invention will be explained below based on the drawings.

FIG. 1 is a diagram showing the basic concept of this invention.

In FIG. 1, 1 is the backrest main body,
It is composed of a back support plate (a) and a support arm (b). Reference numeral 2 denotes support stands, which are arranged as a pair horizontally opposite to each other on the left and right sides, and whose tips are curved inward and protrude to the front so that they can be opened and closed. Then, the bases of the left and right support arms B are connected to the support stands 2, 2, and the connecting parts are pivoted 3, 3, and the entire support stands 2, 2 are connected with the pivot parts 3, 3 as fulcrums. In some cases, the bases of the support arms (b) and (b) are fixed on the support bases 2, 2, so that the support bases 2, 2
In some cases, the tip is extended slightly forward, and only the pivoted tip part can be opened and closed. In addition, the supporting arms B and B are
It can also be configured to be able to slide back and forth on the supports 2, 2 so that the angle can be changed together with the backrest that forms part of the main body 1. 4 is the space, a table on which to sit;
In other words, it is a part without a board on which to sit down, and the supports 2, 2 are formed so as to surround the waist on both sides thereof.

(Function) Lift the upper body and open the tips of the supports 2, 2 from the back of the seated upper body, pull the backrest A together with the main body 1 so that it comes into contact with the seat back, and in the space 4 of the supports 2, 2. Close the tips of the supports 2, 2 inward so as to narrow the waist, insert the protruding portions of the tips under the thighs or the base of the thighs, and press from above with the thighs. As shown in the figure, it is placed on the backrest A. In addition, when discontinuing use and taking out the backrest, open the ends with your hands on both sides and pull it out from under the thighs or the base of the thighs. In other words, all you have to do is support the backs of crippled people, bedridden elderly people, sick people, etc. with your hands and then put them back to sleep (Example) In the examples described below, the same reference numerals refer to the first
It shows the same parts as in the figure.

FIG. 2 is a diagram showing an embodiment of the present invention,
To explain its structure, the main body 1 is composed of a backrest A and a support arm B. 2 is a support stand,
The lower ends of both support arms B are fixed to the upper surfaces of the left and right support stands 2, 2, and the support stands 2, 2 are extended a little longer forward and backward around the fixed parts, and furthermore, the support stands 2, The fulcrums 6 of the curved rods 5, 5 are provided at the tips of the rods 2 and connected to each other so that they can be opened and closed freely.

Next, to explain the operation, the curved rods 5, 5 are opened from the back of the upper body raised in a sitting position, and the backrest A is pulled together with the supports 2, 2 from behind so as to be pressed against the back, and the space part 4 is They are held together so that the lower back is present, and the tips of the curved rods 5, 5 are inserted into the thighs or the bases of the thighs, and the weight of the thighs presses down from above, and at the same time the upper body is used by leaning against the backrest A. If you wish to stop using the patient next time, simply pull out the tips of the curved rods 5, 5 from under your thighs, then pull out the backrest body 1 backward while temporarily supporting your upper body, and let the sick person lie down. .

Next, in the embodiment shown in FIG. 3, the main body 1 is composed of a backrest A and a support arm B, and a horseshoe-shaped support base 2 whose tip part opens and closes on the lower side of the mounting plate of the support arm B.
Two fulcrums 7 are provided, and the interior of the support stands 2, 2 is formed into a space 4 without a stand on which to sit.

Next, the action will be explained.

The action in Figure 3 is almost the same as in Figure 1,
First, open the supports 2, 2 to the left and right and open the ends, then raise the upper body of the sick or disabled person, and insert the openings of the supports 2, 2 from behind from both sides of the waist. , in the space 4, hold the lower back between the supports 2 and 2 from the left and right so that it is in contact with the back of the backrest A, insert the tip of the lower part of the lower back into the lower part of the thigh, and gradually lie the upper body backwards and rest on the backrest A. Let them support you. Next, when taking out the supports 2, 2, pull out the tips of the supports 2, 2 from the underside of the thighs, pull them out backwards with the supports 2, 2 open, and remove the patient. All you have to do is place the disabled person in that position and let him lie down.

Next, the embodiment shown in FIG. 4 will be explained.

In FIG. 4, a main body 1 is formed by a backrest A and support arms B and B, and the lower ends of the support arms B and B are fixed on U-shaped support stands 2, 2. A space 4 is formed between and 2. Reference numeral 8 denotes a protrusion, which is loosely inserted inward from the tip of the support bases 2, 2 so as to be freely removable.

This operation is similar to each of the conventional embodiments. The only difference is that a person with a disability or illness, etc., raises his or her upper body and inserts the openings of the supports 2, 2 into which the protrusion 8 is retracted from behind, from both sides of the waist.
Pull the backrest A against your back,
After inserting the protruding part 8 into the lower side of the thigh, all that is required is to gently lean the upper body back against the backrest A. Next, when the support stands 2, 2 are to be taken out, the left and right protrusions 8 are pulled out from the lower side of the thighs and taken out to the back, as in the conventional embodiment.

(Effects of the invention) This invention opens and closes the support stand itself, which has a backrest without a stand to sit on, so that crippled, bedridden, elderly, and sick people can raise only their upper bodies, keep their lower back on the floor, and sit on their backs. Since it can be inserted and removed more easily, it reduces the labor required by conventional nurses, and it is easy to use and has many practical benefits for users.
