DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elderly or sick person who is unable to move on his own by himself in a wheelchair without any care by a single caregiver or without any caregiver. The present invention relates to a structure of a wheelchair that allows a user to sit down on a toilet seat and use the toilet.

[0002]

Background of the Invention Recently, the number of wheelchairs has been greatly increased, and the range of action has been widened for the elderly and the sick and disabled persons with leg disorders, especially for the elderly or the sick who cannot move their bodies. Is used by some people to move to a laboratory in a facility or hospital, or to receive consultation from another department,
Anyone who can move a little has some benefit, such as going to the cafeteria in the facility himself and omitting the labor, and also exercising. But it's a matter of whether it's useful where it's really needed.

[0003] However, in reality, even an elderly or sick person who can hardly move their body (hereinafter simply referred to as sick person) wants to use only the toilet in the toilet, but is required to be put on a wheelchair by a caregiver. Even if you go to the toilet, getting down the wheelchair and sitting on the toilet seat requires a great deal of effort by the caregiver alone, and of course it is rarely necessary to go to the toilet because you can not do it yourself. The cause is lack of wheelchair function.

[0004]

SUMMARY OF THE INVENTION The present invention eliminates the labor of raising and holding a sick person from nursing care, so that the caregiver can use the toilet without using the labor or in the wheelchair independently of the sick person. It is intended to provide a structure of a wheelchair that allows the user to sit and use the vehicle.

[0005]

The wheelchair according to the present invention is a combination of an outer frame and an inner frame. The outer frame frame supported by the front wheels of two casters and two rear wheels is a caster. A horizontal member connecting the left and right sides of the inclined member, a footrest, an armrest, a back portion of the outer frame, a pushing portion, and a connecting rod connecting the left and right frames at the upper portion, and other horizontal members and wheel supporting members; The inner frame is formed by an inner frame horizontal bar connecting the left and right frames at the seat part, the inner frame back part and the upper part, and both frames can be rotated at the intersection of the seat frame front extension of the inner frame and the outer frame inclined member. So that the screw rod is mounted at the center of the outer frame upper connecting rod so that the tip can rotate up and down, and the screw rod passes through the center of the inner frame upper horizontal bar so that it can be rotated vertically. Provide a passage cylinder, and rotate the screw rod to the part that has passed through the cylinder. A female screw cylinder with a dollar to screw coupling the threaded inside and outside frame. Or, if there is no caregiver, reverse the position of the screw rod and the female screw with handle, fix the female screw cylinder to the passing cylinder, rotate the screw rod with the handle on the sick side without rotating, The handle at the back of the neck is difficult to operate, but the handle without the handle removes the need for a caregiver. It is more convenient for the inner frame back to be located behind the outer frame back.

[0006] The seat sheet enables the inner frame seat to be slid back and forth by means of a tubular object or a ring on both left and right edges. In front of the seat, cut out an oval hole of about 20cm in width and about 35cm in length at the center in accordance with the toilet seat in the center, and in normal times, wind it into the winding cylinder under the seat with a spring force or by hand. The seat is pulled up rearward along the inner frame and the oval hole is aligned with the toilet seat. The lifting structure fixes the pulling bar to the rear edge of the seat, and grips it at the time of pulling up, and also fixes both ends of the belt or rope slightly longer than the bar to the part protruding from the seat at both ends of the bar. If a pulling rope is connected to the midpoint and the rope is pulled with a stronger force than the spring of the winding cylinder via a pulley provided on the back of the inner frame, the seat is pulled rearward and pulled up. The other end of the pulling rope is hooked to a catch on the underside of the armrest using a second pulley or a slippery guide surface.

[0007]

[Function] When the toilet is used, the wheelchair is pushed backward to the position suitable for the toilet while the sick person is placed on the toilet seat with the lid open, and the brake is applied. Next, in order to receive the weight of the sick provided on the outer frame, the belt-shaped weight support device such as a plastic or the like provided on the outer frame upper connecting rod is put under the sick under the sick, and then suspended. If you rotate the operation handle of the screw bar to widen the space between the back of the inner frame and the back of the outer frame, the inner frame seat lowers. If you lower the seat of the inner frame by 4 to 5 cm, the sick body will be in a floating state. The leading edge also falls,
There is a gap between the seat surface and the body and below the knee. At this time, the patient's weight is completely separated from the seat, so the seat can be pulled out to the rear of the inner frame, and the drawer end is pulled up along the inner frame so that the oval hole of the seat overlaps the toilet seat. Through the pulley, fasten the front end of the pulling rope to the latch below the armrest. At this time, remove the waist clothing.
Next, rotate the handle of the screw rod to bring the back of the inner frame closer to the back of the outer frame.The inner frame seat rises and receives the weight of the sick, so remove the weight support from the armpit of the sick, and then remove the handle. If it rotates and lowers the inner frame seat portion to the toilet seat, it can be used as it is.

When the stool is completed, the handle is rotated to raise the weight of the inner frame seat to a level at which the weight support can be put under the patient's armpit to support the weight, and then the handle is rotated to lower the inner frame seat. If the rope is removed from the latch on the underside of the armrest at the same time as creating a space between the body and the waist clothing, the seat will be wrapped around the front part by the spring or manually, and the seat Both ends are caught by the wheel support member and stop at the normal position. Finally, by turning the steering wheel to raise the inner frame seat to the normal height and removing the weight support, you can run as a normal wheelchair.

[0009] In addition, if the patient is sick or handicapped who has strong arms and hands, it is possible without a caregiver. In this case, the screw rod is rotated with a handle attached to the back of the occupant's neck. It may be mounted so as to be rotatable in a vertical plane. However, if desired by the user, the handle can be mounted at an easily operable position by using a flexible shaft, gears, a roller chain, a universal joint, or the like instead of the handle, although it is complicated.
