Abstract

Provided is a wheelchair whose seat surface rises and falls according to the height of a table when eating.
An air compression pump (4) and a battery or a battery (5) are attached to the bottom of an air bag (2), and the air bag (2) provided with a seat surface (3) is installed on a seat surface (7) of a wheelchair. A person sitting in 3 lifts the body by operating the air compression pump 4, and when using a normal wheelchair 9, the air in the air bag 2 is exhausted by the exhaust valve 8. Can be moved.

Description

Since the present invention has a difference from the table when eating in a wheelchair, a thick cushion is laid on the seating surface, but a thick cushion is not required except for meals.

Because the seating surface of a conventional wheelchair is low, there is a difference in height from the table, and a thick cushion is laid on the seating surface of the wheelchair during meals. Does not reach the floor.

The air bag that is inflated with the compressed air pump is installed on the seat surface of the wheelchair, and the air bag is inflated with the air compression pump during meals, but the height to be inflated is about 10 cm to 15 centimeters, There are differences in height depending on the person, but I think 10cm is good.

Attach the air compression pump and battery or battery to the lower surface of the air bag, install it on the seat surface of the wheelchair, sit on the seat surface of this air bag and turn on the air compression pump. I think that the height limit is about 10 cm. In addition, in this state, the floor does not have a foot, so when the air is removed from the air bag and the body is lowered, the foot is attached to the floor.

Half of the people in the advocacy facilities use wheelchairs, but because Japanese people have short legs, if they raise the seating surface of the wheelchair, their feet will not reach the floor, so in ordinary wheelchairs the height of the seating can be bald with feet However, when the air compression pump is turned on, the body rises and the height of the table disappears, making it more enjoyable to eat.

Best mode for carrying out the invention

When using the wheelchair, half of the people turn the wheel with their hands or crawl with their feet and move around, but if they stick to the table in that state, it is difficult to eat because the table is high, so wheelchair A thick cushion is placed on the seat surface and the height is adjusted, but the foot is not used as it is, so it is usually used with the cushion removed.
In this device, the air bag that is moved up and down by the air compression pump is installed on the seat surface of the wheelchair, and the person is sitting on the seat surface on the upper surface of the air bag and the air compression pump is turned on to lift the body, but it is raised about 10 cm This is the limit, and during normal use, open the exhaust valve and lower the seat.

An air compression pump 4 and a battery or a battery 5 are attached to the lower part 1 of the air bag 2 in FIG. 2, and a seat surface 3 is attached to the upper part of the air bag 2. The switch 6 is taken out from the air compression pump 4 in the lower part 1 of the air bag 2, the exhaust valve 8 is attached to the air bag 2, the bottom 1 of the air bag 2 is installed on the seat surface 7 of the wheelchair 9, When a person sits on the upper seat surface 3 and the switch 6 of the air compression pump 4 is turned on, the seat surface 3 of the air bag 2 rises and there is no difference in height from the table. In addition, after the meal, the air is removed from the air bag by the waste air valve 8 and used at the height of the seat surface of the conventional wheelchair 9.
In this device, it is not necessary to remove a thick cushion at the time of eating, and if it is necessary to inflate an air bag of this size, a small battery or four single 6 dry batteries are sufficient.
When using a battery, a single charger is sufficient for individuals. However, since half of the facilities use wheelchairs, it is better to have 10 or more connected chargers.

Claims (2)

Attach an air compression pump and battery or battery to the lower part of the air bag, install an air bag with a seat on the top of the air bag on the seat of the wheelchair, and the person sitting on the seat above the air bag will compress the air Lifting the body by operating the pump, when using a flat wheelchair, the air in the air bag is exhausted by the exhaust valve, and when you lower the body, you can move the wheelchair because the feet stick to the floor. Is a wheelchair that goes up and down with an air bag. A person who sits on a chair with an air compression pump and a battery or battery attached to the lower part of the air bag with a seating surface on the upper surface operates the air compression pump to raise and lower the body. A wheelchair where the seating surface moves up and down with an air bag.
