[Technical field to which the device belongs]

 The present invention relates to a sitting chair whose height can be adjusted and which has fall prevention.

[0002]

[Prior art]

 Many of the traditional sitting chairs are made only of the average size of Japanese people, the sitting area is small, and many of them are tired. I get tired when I sit for a little while after sitting down, and it becomes a pain to sit down unless I change my hip position from time to time. At that time, he often falls to the rear. When sitting straight, the heels of the left and right feet are always on the soles of the feet, so they hit the buttocks and support half the weight of the upper body. That causes pressure on the ankles and heels, causing numbness in the legs, loss of sensation in the legs, loss of freedom of movement, and an instant inability to move to the next action, causing a fall. Further, in the conventional products, when there are leg plates on both outer sides, both legs are restricted to the leg plates from the outer side, the distance between both knees is narrowed, and the sitting position is difficult for a large person. Even if you can change the seat height, you will not be in a comfortable sitting position.

[0003]

[Problems to be solved by the device]

 In the present invention, the leg plates supporting the upper seat plate are set as a pair, and the leg plates stand in two rows at 10 cm in front and 6 cm in the rear from the center. A rear fall prevention unit with a length of 12 cm is provided at the rear of the unit. The reason for bringing the leg plate to the center is that there is no doubt that a person called a person is mentally tired but physically tired when standing upright with the heel attached. When you take the "rest" attitude, you can relax and relax, both physically and mentally. It is exactly the same when sitting straight down. If you sit with your front knees open about 10 cm (15 cm depending on your build), you will have a comfortable posture. In this case, there is no fear of falling sideways. By increasing the base of the sitting posture and increasing the stability of the sitting posture, when sitting long, it is possible to sit comfortably mentally and physically. Taking this fact into consideration, I brought a leg plate near the center.

When sitting continuously in a sitting position for a long time, the weight of the upper body is directly applied to the bent leg, and the leg, particularly the ankle and the heel are subjected to heavy pressure, and the muscles and blood vessels exert weight pressure. If you receive it, you may get numb, and you may lose the sensation of your legs and fall. In order to prevent such a condition, the left and right ends are removed in a semicircular shape as shown in Fig. 6 at the rear of the upper seat, and the heel of the ankle is exposed in the space with the back of the ankle up. , The ankles are free to move and no upper body weight is applied, so even if you sit for a long time, you will not get tired. The bent part of the knee in the front part is the height of the upper seat body to the extent that it does not transmit the pressure of the thigh to the thigh, and the weight of the seated person and the thickness of the thigh are the most comfortable for him. Position the leg plates parallel to each other or move up and down to adjust the position so that the thigh pressure is not transmitted to the thighs. As a result, the weight pressure on the bent part of the front part of the knee is prevented, the knee part and the heel part are eased, and the sitting position for a long time can be comfortably spent.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the sitting chair of the present invention can prevent the fall and eliminate the anxiety by adding a fall prevention part to the rear part. In addition, three types of sitting chairs, S type, M type, and L type are made, and the seat height can cover most of the Japanese, that is, it is designed so that it can be adapted to a person from 35 cm to about 95 cm. It is a property The seat type is S type, which can be adjusted to 4 steps of height of 7 cm, 8 cm and 9 cm from the height of 6 cm, and the M type is 4 levels of 11, 12, 13 cm from 10 cm to 1 cm. And the L type is the one that can be adjusted in 5 steps from 14 cm to 18 cm. Even if the body weight is the same, there is often a difference in body shape between the thighs and thighs. Considering the thickness of the thighs, the pressure of the thighs of the person sitting upright is not applied to the knees and thighs. However, it may happen that the seating body is slightly raised and the person who sits upright sits at an appropriate height.

[Embodiment of device]

 The assembly method is that the leg plate body 2 is erected on the body upper plate portion 1, the leg plate body 3 is inserted in the body portion 4 and the front portion of the leg plate body 3 is inserted from the rear side of the body upper plate portion and left there. Align the 5 body located at the front of 3 with the front of the leg plate body 2 and fasten with 11 metal fittings patchons. The assembly is completed by fixing the rear body 6 after the leg plate body 2 with the metal fitting patchon 11 of the fitting 11. When disassembling, the front and rear patchons 11 are removed, the leg plate body 3 is pulled out backward, the leg plate body 2 is laid down sideways, and the main body upper plate portion 1 and the leg plate body 3 are stored in a storage bag.

For example, when it is considered that the seat plate 11 cm in seat height is appropriate for the person in question, two front and rear leg plates are set as a set, and the front leg plate is the A plate back plate and the B leg is the back plate. In this case, all nuts are embedded in the holes of plate B, so turn the bolts into the holes of number 11 on plate A from the threaded part of the bolt part of the nut. The work is completed by tightening all four with a small spanner. It takes about 10 minutes to complete.

A cushion having a size suitable for sitting on a sitting chair can be attached with a magic tape, and only that item can be washed by itself for removal. Also, put a hard sponge in the center to ease the pressure on the upper body.

[Effect of device]

 As described above, according to the present invention, the height can be adjusted according to the physique, weight, and the thickness of the foot, and the disassembling and assembling operation is easy, which is convenient for carrying. Moreover, by adding the fall prevention unit, you can sit down comfortably for a long time without the fall prevention and the anxiety. Further, when the right and left end portions of the seat plate body shown in FIG. 6 are raised to 1 cm above the parallel lines, the leg portions can be moved easily.
