Description

An indoor wheelchair for elderly people who strongly desire home care

Previously, a letter in the local newspaper, Niigata Nippo, stated that the current wheelchair is very difficult to use at home, inconvenient, and that it would be easier to use.
Therefore, I thought that it would be useful even a little, I made a lot of ingenuity and made a wheelchair for home use only.

The first requirement for a wheelchair that is easy to use in the home is small and compact, can be changed 360 degrees in a stationary state, can be used in a narrow home corridor, etc. The second is a car in a narrow toilet Entering a chair and making it easy to use, a portable toilet on the side of the bed is good, but the room smells bad, and the elderly also want to go to the bathroom. Third, go to the bathroom with a wheelchair and help It's hard work for the elderly to be able to help bathing easily, especially in the bathroom, hugging the elderly and putting them in the tub.

In order to enter a narrow toilet, etc., the tilted backrest and the footrest angle can be changed vertically or changed into a tilted shape, and the main structure of the wheelchair frame is a rectangular box structure, and the rear part Make a hollow underneath the half of the seat and under the seat so that the toilet can fit completely there, and make a toilet hole in the seat to make a toilet hole, and a lid that opens and closes there Then, pull out the lid so that it can be used, back the wheelchair backwards, enter the toilet, cover the toilet bowl with a lid, and even a serious person can sit on the wheelchair and use it as a wheelchair. In addition, the seat is made to be a slippery structure so that the elderly can be slid without lifting up, transfer to the bed, etc., when taking a bath, attach another slide plate that matches the height of the bathtub, making it a high seat, Separately, prepare a slide plate for bathing, Put it on the bathtub and slide it from the high seat of the wheelchair to the sliding board for bathing without lifting the elderly, and transfer and bathe. Prepare a separate sliding plate for the bed and use an electric reclining bed whose height can be changed

The low seats with different heights and the slide plates provided on the high seats allow the transfer from wheelchairs to beds, bathtubs, etc. to be slid without lifting the elderly, and caregivers are freed from heavy labor. In addition, when bathing, the dedicated bathing slide plate is transferred to the bathtub in a bridge shape, and the bed is also transferred using the dedicated slide plate, but the bed can be changed in height. When using the electric reclining bed, when entering the toilet, as a pre-preparation, if the reclining angle is set up vertically by operating the rear folding stopper, the backrest will be the same vertical, and the front When the leg rest is lowered vertically by operating the folding stopper on the leg rest, the wheelchair can turn, and the toilet cover is pulled out from under the front of the low seat, and the wheelchair is When you enter the toilet, you should bend your knees and put your feet on the front. Because it is a universal wheel, it can be moved to the side like a crab with a 360-degree change of direction when it stops, and it can be used in small homes. Easier to bathe, transfer to bed, etc., free from heavy labor

The seat of the wheelchair is composed of two seats of different heights: a high seat and a low seat. A part of the front of the low seat is cut and attached with a hinge so that it can be tilted and held freely. When the front is lifted and slanted, the support angle provided on the back is automatically supported to provide a comfortable ride, and a cushioning material is applied to the surface of the general seat, making the surface smooth and slippery. The slide plate is made by pasting the seats, and it can be slid and transferred to the bed or the like without lifting the elderly. In addition, the oval toilet hole is roughly oval on the low seat slide plate. The toilet cover is covered with the same shape toilet cover, and the toilet cover is attached with multiple L-shaped angles on the back of the toilet hall, supporting the toilet cover, and raising the front of the seat. Previous A structure that pulled out to a bed ERROR to the others, the elderly, with no slip caused by ERROR can it is a feature that the lift in one's arms, and the low seat slide plate, the toilet hole and toilet cover, car chair with

The high seat is also a cushion plate on the surface, and a slide plate with a smooth surface and a slippery slide is bonded together, and it can be slid without lifting an elderly person and transferred to a bathtub or the like. The part slide plate is used for bathing, because the height of the helicopter of the bathtub is higher than that of the toilet bowl, and the generally high seat part is attached with a rotary joint at the rear, and is held freely. When not in use, raise the front part of the high seat, raise it, overlay it on the back and back, and stop it with a stopper. Attach a pivoting retractable leg that is pinned, rotate the retractable leg 90 degrees and pull it out. When the general seat is tilted horizontally, the retractable leg maintains the difference in height between the seat and the seat. Used when taking a bath It can ERROR to use slide plate, bathing the surface sliding plate, on the back, pulling legs and, wheelchair having a dais portion consisting of a backrest front

The legrest in front of the wheelchair is attached to the upper part of the front horizontal frame with a cross joint at the upper end, and is pivotably held. Underneath, the outer arm and the free arm that connects the inner cylinder extend and retract with a double cylinder structure. It is characterized by being held freely, a hanging joint is arranged on the outer cylinder and a bending joint is arranged on the inner cylinder, both of which are connected by a hanging bar, and the bending joint is held so that the angle can be changed freely. When the angle joint is tilted, the friction is generated between the inner cylinder and the inner cylinder is locked and stopped, and the height is maintained. When the bending joint is leveled, there is no friction with the inner cylinder, and the inner cylinder can be raised and lowered freely, so that the leg rest that can be locked by changing the height of the leg rest freely, Equal length Two angles are pivotally connected with a pin, and one end is attached to the outer cylinder of the free arm and the other end is pivotally attached to the front frame. When the folding stopper is folded, both ends are shortened, the continuous leg rest is vertical, and when the folding stopper pin is pushed, the both ends are straight and the continuous leg rest is front It is also characterized by being able to go out, tilt, lock, and change the legrest to two angles, and when entering a narrow toilet, if the legrest is vertical, the wheelchair will be compact and the turning will be small The foldable stopper that can be folded is attached with a L-shaped stopper to prevent overrun, the height can be freely changed and locked at two angles, Guresuto

As above, in order to allow the wheelchair to turn slightly, the backrest part is supported, and the reclining angle is pivotably attached to the left and right of the rear part. In addition, when two sets of vertical stopper and tilting stopper are arranged in the front and rear, the reclining angle is vertical, and the front vertical stopper pin is pushed down, the stopper can be extended and locked in a straight line, When tilting the reclining angle, first raise the pin of the vertical stopper, the stopper will bend and contract, and the lock will be released.Next, tilt the reclining angle and lower the pin of the tilting stopper. The stopper is also characterized by its ability to extend and lock in a straight line. Also, because the slope to the rear can relax, and when the backrest portion of the vertical-like, at the time of the tilt-back, two-point reclining angle that can lock

The lock brakes on both the left and right sides have a short frame that extends rearward at a right angle below the front frame. A brake lever is pivotally attached to the tip of the lock brake, and a short angle is placed on the lower end of the brake lever. A slightly longer angle is pivotably connected to the angle, and a slightly longer angle is pivotally connected to a tachi band attached to the short frame, and the slightly longer angle and a slightly shorter angle. A non-rotating wheel that is not stopped by a pin is attached in the middle. The non-rotating wheel is lowered when the brake lever is pulled backward, and at the same time, the front wheel is lifted about 5 to 6 mm from the floor. In addition, it has a stop to prevent overrun between the brake lever and a slightly short angle, With a short angle and a short straight line, it stops at a position where it overruns about 5 to 6 degrees in angle, and it can be locked by wheelchair load, with a lock brake, and when the brake lever is pushed forward, The brake is released, the lock brake

The front-up device below the front part of the internal space under the seat is arranged in the front and rear direction, the frame is arranged on the left and right sides, the frame along the left and right lateral direction is arranged on the front and rear, and assembled in a square shape, The left and right frames along the front and rear are stretchably held by a double cylinder structure, and the front end of the rectangular frame is a horizontal frame that extends to the left and right under the front frame by a cross joint. This device is equipped with a steel wire that is pivotally mounted, and has a steel wire that is fixed at a fixed position when the wheel is mounted on a frame extending downward at right angles immediately after the cross joint, and the double cylinder frame is extended. When not in use, keep it up, and when using it, hold the rear part of the square frame and lower it down. Arrow D, pull, the double cylinder frame will stretch and stop with steel wire.
