DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for moving a disabled person, a sick person, or an old man with a weak leg (hereinafter simply referred to as a sick person) from a head to a wheelchair at home, a hospital, a nursing home, etc., without putting effort on a caregiver. In addition to moving from the chair or wheelchair to the head, the use of a hanging cloth allows the sick person to be lifted in a horizontal or sitting position, saving the caregiver's effort.

[0002]

BACKGROUND OF THE INVENTION Wheelchairs are currently most convenient to be transported and stored, and are equipped with a folding function, which is the most popular and excellent indispensable for moving sick people. However, only a folding function is added. Naturally, I would like something that has more functions related to nursing care. The care of the sick is performed in hospitals, nursing homes, homes, etc., but in most cases the area around the beds is so narrow that there is no room for nursing equipment. It can be stored in a separate place in hospitals and facilities, but in the case of home care, which accounts for most of the care of the elderly, a wheelchair can be set up by placing a bed in a room of about 6 tatami mats so that the caregiver can enter around. However, it is normal that there is no room to put a lift etc.

[0003] Caregivers most struggle with moving the sick. Wheelchairs can solve long horizontal movements, but even the slightest horizontal and vertical movements in and around the bed can be very difficult for caregivers, and may not be possible for elderly women who do most of their home care. Many. In such a case, it is sufficient to have a lift, but it is difficult to own one for each caregiver because the conventional lift takes up space and has no place to place and is expensive.

[0004]

In addition to simply carrying a sick person in a wheelchair, the sick person lying on a bed is lifted by supporting both shoulders or armpits, sitting on a wheelchair seat, or being lifted horizontally. An object of the present invention is to detachably attach a lift member, which can be moved to a device, to a wheelchair, thereby saving the occupied area of the lift device and reducing the price.

[0005]

According to the present invention, other members are attached to a four-wheeled wheelchair regardless of the presence or absence of a folding mechanism so that they can be used as a lift. This device can be used as a four-wheeled wheelchair. A short pipe with a bottom is fixed along the front surface of a vertical member formed by bending the front part of an armrest of a four-wheeled wheelchair vertically, and a weight supporting column for lifting a patient is detachably inserted into the short pipe with a bottom. The upper part of the left and right pillars is inclined forward, the upper part is connected, the hoisting shaft equipped with the winding drum of the lift rope is attached to both ends in parallel with the upper connecting member, and the weight hanging under the patient's armpit at the lower end of the rope The support is hung, the hoisting shaft is rotated by a deceleration motor attached to a member parallel to it, and another short pipe with a bottom is placed horizontally along the inside of the horizontal part at the front of the front and rear wheel connecting member. Fixed to
The wheel support rod for preventing the vehicle from tipping over or a simple rod or pipe is detachably inserted, and a rear pulling rope with a hook at one end hooked on the weight support is passed through the pulleys on the lower side of the hand pushing part and the rear end of one armrest. It is configured to be manually or electrically wound around the rope drum of the worm reducer fixed to the back of the vicinity, lift the upper body of the sick person in the sleeping position, change the caregiver to the forward kneeling posture, and lower it when reaching a certain height This is a wheelchair with a moving lift from a bed that pulls a sick person backward and sits down while pulling a backward pulling rope.

In order to mount the motor on the upper part of the column in parallel with the shaft, one lower connecting member is further required. The upper part of the column becomes heavier due to the presence of the motor. It becomes difficult. Therefore, once the column upper frame including the upper connecting member is separated, the column upper frame itself, the connecting member,
Shafts and parts are made of aluminum or plastic as much as possible to make them lighter, and removably attached to weight support columns. Attach a safety cover to the machine parts and motor of the hoisting shaft.

[0007] Both ends of the rope are fixed to the rope drum flange of the hoisting shaft, and the middle part hangs down near the head of the sick person in the sleeping position,
Hooks are attached to both ends of a plastic length adjusting tube having a length of about the chest width which has been passed through in advance, and an L-shaped weight support is hung on this hook and inserted under the patient's armpit. The length adjusting tube is used to adjust the distance between the shoulders of the sick and the left and right drums, which varies depending on the posture of the sick. A light plastic gear is fixed between the two drums of the shaft. When the switch is turned on, it meshes with the small gear of the reduction motor to rotate the drum and lift both shoulders of the sick. In addition, the cross section of the column and the short pipe with the bottom is not limited to a circle but may be a corner.

[0008]

The rope winding shaft and the deceleration motor are more stable when mounted on the lower part of the vehicle body. However, the strength of the pillar and the motor capacity must be doubled, and they are mounted on the upper part in consideration of the price.
To move a sick person with weak legs from a bed to a wheelchair, first raise your knees, lift one arm at a time and fit your weight support under the armpits,
Lay the head support cloth under the head so that the neck can not be seen, hang those left and right ropes on the hooks at both ends of the length adjustment pipe,
Turn on the motor up switch. First, the head is slightly raised, then pulled up with the shoulders, and the upper body is raised.
When the neck sits on the way, the head support cloth naturally slips and falls on the shoulder, so it can be removed at any time. When the waist rises from the bed, the caregiver turns the sick 90 degrees to the opposite side of the wheelchair. At this time, the caregiver requires almost no labor. When the buttocks of the sick are raised about 10 cm above the seat surface of the wheelchair, the lift is switched to lowering, and the lowering switch is turned on and off so as to keep the rear pull rope approximately horizontal, and the user is seated on the wheelchair. Keeping it about level is the easiest for caregivers. Since the legs remain on the bed, the caregiver supports the legs and gently lowers them while retracting the wheelchair. To move from a wheelchair to a bed, reverse the above steps.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In this embodiment, the lift device uses an electric motor, and the winding drum of the rear pull rope uses a manual handle. As shown in FIGS. 1, 2, and 3, when the lift device and the electric motor are attached to the upper part of the pillar, the weight becomes heavy and it becomes difficult to assemble by a single woman. A short pipe 2 with a length of about 30 cm is fixed along the front surface of the vertical member 1, and left and right weight supporting columns 3 having a height of about 160 cm from the floor, and an upper part of about 40 cm are inclined obliquely forward by about 30 degrees. It is bent and removably inserted, and the aluminum column upper frame 4 having a height of about 30 cm is removably inserted and fixed. The hoisting shaft 6 provided in parallel with the upper connecting member 5 at the upper end thereof is attached to the rope drum 11 and the nylon gear 12 at both ends, and is welded to the upper aluminum cylinder 7 fitted to the surfaces of the left and right column upper frames 4. A motor support cylinder 14 made of steel pipe is previously fitted to a lower connecting member 13 supported on the bearing ring 9 via an oilless bearing 10 and further welded to the inside of the lower aluminum cylinder 8, and a base plate of the reduction motor 15. 16 is fixed by welding. Therefore, the speed reduction motor 15 is not fixed to the lower connecting member 13, and it is necessary to determine the meshing between the small gear 17 and the gear 12. In this example, a part of the base plate 16 is bent to surround the outer periphery of the deceleration motor 15, and a part thereof is fastened and fixed on both sides by an adjustment bolt 18 rotatably attached to the upper connecting member 5. According to this structure, it is possible to fix the motor and change the combination of the gears to change the lift hoisting speed.

The aluminum column upper frame 5 has a hoisting shaft 6
, The motor support cylinder 14, the base plate 16 and the bolts are made of steel, and the other parts are made of aluminum or plastic. However, only the outer frame of the deceleration motor 15 is cast aluminum, but the contents are conventional materials. Thus, the in-post equipment would be significantly lighter and almost all women would be lifted. However, it is safer to mount the wheelchair forward or backward on the floor. Also, a short pipe 21 with a bottom is fixed horizontally by welding along the front inside of the front and rear wheel connecting member 20 so as not to come out in front of the inclined member 23 for supporting the footrest, and a caster 22 is provided at a tip end of about 40 cm. The other end of the handle is inserted into the short pipe 21, and the caster is detachably fixed so as to float about 1 cm from the floor. If the caster cannot be inserted due to the lower part of the bed, a support rod or a support pipe 22 connecting both ends may be used.

Further, as shown in FIGS. 4 and 5, a lift rope 24 having both ends fixed to the rope drum 11 has an intermediate portion hanging above the head of a sick person in a sleeping posture, and both ends of a length adjusting tube 25 previously passed through. And a head support cloth 27
The both ends of the rope whose length is adjustable and the both ends of the rope on which the L-shaped weight support device 28 to be inserted under the armpit is hung. Since the left and right lengths of the lift rope vary depending on the posture of the sick and the position of the wheelchair, the left and right lengths are adjusted by the length adjustment tube 25. When the patient's knee is raised and the switch of the motor 15 is turned on and the shaft 6 is rotated, the weight support 28 slightly idles, so that the head is raised first, then the shoulder is raised, and the upper body is raised. For this purpose, the length of the head support cloth 27 is made adjustable so that the neck is not overloaded. Then, the hips are lifted, so turn your body slightly away from the wheelchair and lift both knees upright. If the buttocks rise slightly above the wheelchair seat, switch to the down switch.
It is easy to pull the rear pull rope 32 approximately horizontally, and one end is hooked on the lower hole 29 of the weight support device 28, and the other end is fixed to the rear back of the armrest via the left and right pulleys 30 under the hand pushing part. Since it is wound around the rearward pulling drum 33 of the machine 31, the detachable handle 34 can be turned to pull the upper body to a position above the seat.

According to the present invention, a caregiver can move a sick person directly from a bed to a wheelchair with little effort. Also, if the lifting parts are removed, they will fit in a small box and will not shrink the room. By using a supporting cloth such as a head, a waist, a thigh, and a leg together with a weight supporting device, the sick person can be lifted from a bed in a horizontal or sitting posture, and can be used for movement and other various care work.
