Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chair for assisting a person with a physical disability to wake up when a bedridden person, such as a sick person or an elderly person, gets up from a bed.

In this specification, the term "bed" includes not only a bed but also a bed such as a bedding on the floor.

[0003]

2. Description of the Related Art Bedridden persons with illness and the elderly are
When adding stools or moving in a wheelchair, the caregiver lifted the body of the physically handicapped person and pulled him up from the bed. This is a considerable burden on the body, and especially when the handicapped person has a heavy weight, a single caregiver may hurt the waist and the like, so that it may be necessary to assist several people.

Therefore, in order to reduce the burden on the caregiver, a device has been devised and put into practical use, in which a disabled person is wrapped in a cloth sheet, and the electric lift lifts the entire sheet to wake up from the bed.

[0005]

However, since the above-mentioned device lifts a disabled person with an electric lift, the disabled person often feels anxious and dislikes its use.

The present invention has been made in view of the above-mentioned problems, and it is possible to reduce the physical burden on the caregiver when the physically handicapped person gets up and the like, and at the same time, to give the physically handicapped person anxiety. It is an object of the present invention to provide a device for assisting the getting up of persons with disabilities.

[0007]

In order to achieve the above object, a chair for assisting the wake-up of a physically handicapped person according to the present invention comprises a lower fixed portion and an upper lift portion which is attached to the lower fixed portion so as to be movable up and down. It has a leg arranged on the side, a seat plate whose one side is attached to the elevating part of the leg, and a backrest plate which is connected to the rear end of the seat plate so as to be able to rise and fall. It is designed to be rotatable around the elevating part.

The leg is composed of, for example, a fixed part made of a cylinder having a base at the lower end, and an elevating part made of a pillar or a cylinder fitted in or fitted on the fixed part so as to be vertically slidable. The fixing portion may be fixed to a side frame of the bed or the like, or may be fixed to a floor surface on one side of the bed. Further, casters may be provided on the lower surface of the fixed portion so that they can be moved. Examples of means for raising and lowering the raising and lowering unit include a hydraulic cylinder and a pneumatic cylinder, and a combination of a toothed rack and a gear. The size of the legs and the lifting distance of the lifting unit are appropriately set according to the distance between the bed upper surface and the floor surface, the length of the lower leg of the physically handicapped person, and the like. As the material for the legs, stainless steel is preferably used because it is required to have strength for supporting a seat plate, a back plate, and a physically handicapped person, but other metals may be used.

The seat plate is preferably an O-shaped or U-shaped toilet seat-shaped member having a hole or a notch for stools formed in the central portion. Further, a foot rest on which the foot of a physically handicapped person is put may be attached to the front end of the seat plate so as to be slidable back and forth.
The backrest plate is preferably provided with a pillow made of urethane foam or the like on the upper surface of the rear end thereof, and belts for fixing the upper half of the handicapped person are provided on both sides of the pillow. Examples of means for connecting the backrest plate to the rear end of the seat plate so that the backrest plate can move up and down include, for example, those that use an angle adjusting device that connects both plates with a hinge and combines a ratchet wheel and a ratchet. Other means commonly used in chairs and passenger car reclining seats may be used. As with the legs, stainless steel is preferably used as the material for the seat plate and the backrest plate, but at least the upper surfaces thereof are preferably covered with a cushion material such as sponge.

One side of the seat plate is rotatably attached to the elevating part of the leg, or one side of the seat plate is fixedly attached to the elevating part of the leg. By being rotatable about the central axis of the leg, the leg is rotatable about the elevating part. The rotation angle of the seat plate should be at least about 90 °. The seat plate and the backrest plate may be removable from the elevating part of the leg when not in use.
Further, a hinge may be provided at a portion of the seat plate where the leg is attached to the elevating part so that the seat plate and the backrest plate can be stored laterally of the bed when not in use.

[0011]

Since the chair for wakeup assistance for persons with disabilities according to the present invention has the above-described structure, the person with a disability is laid on his / her back and the backrest plate which is tilted backward, and the backrest plate is raised to allow the disabled person to sit on the seatboard. , In this state, the seat plate is raised to a rotatable height through the lifting part of the legs, and then the caregiver moves the seat plate by about 90 ° in the required direction by moving the seat with the foot of the disabled person. After that, the seat board is lowered to a height at which the foot of the handicapped person touches the floor via the lifting portions of the legs. When raising a disabled person, a caregiver can hold the hand of the disabled person and pull it. When the seat plate is in the shape of a toilet seat, a person with disabilities can add stool while sitting on the seat plate. When the person with a physical disability is put to bed, the operation reverse to the above may be performed.

[0012]
