Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The assisting device for persons with disabilities according to the present invention is
For persons with disabilities (hereinafter referred to as physically handicapped persons), a single caretaker is required to move the bedding on the tatami or bed, narrow bathtub, toilet, changing clothes, wheelchairs, and steps between car seats. Made possible with little effort. That is, the burden on the caregiver associated with various kinds of care for the disabled is reduced.

[0002]

2. Description of the Related Art For example, in a conventional bathing apparatus, a rail is provided on the ceiling of a house to suspend and carry a disabled person,
There is a device that allows people with disabilities in their beds to bathe in a special bathtub. The former is not easy to modify a house. The latter does not apply to people with disabilities on tatami mats, and they cannot bathe in the bathtubs normally used in homes. Furthermore, the ability to cross the step is small.

[0003]

[Problems to be Solved by the Invention]

1. To lift a handicapped person in bedding on a tatami mat, for example, or to lift a handicapped person in a bathroom washroom and lower it into a bathtub, the arm must be projected about 50 cm from the device. This condition causes the device to tip over. That is, the first problem is the equilibrium (stability) when the person with a physical disability is lifted above the end of the arm. 2. When the device is moved from bedding on a tatami mat to a bathroom, for example, it usually passes through a corner of a corridor, and the size of the device is limited especially in the bottom area because the bathroom is small. When a person with a disability is suspended and carried by such a device, there is a great risk of falling. That is, the second problem is miniaturization of the device and stability during movement. The third and third issue is increasing the ability to cross steps. 4. When using this device to move a disabled person from, for example, a tatami mat or a bed to the seat of this device, the posture of the disabled person is that the upper body is substantially vertical and the upper thighs (thighs) are substantially horizontal, that is, as shown in FIG. The posture (a) (referred to as a key shape) or the posture (b) (referred to as an L shape) is required. For example, in the posture of (c) (referred to as V-shape), there is a risk of slipping from the seat. Or the seat becomes larger and the device becomes larger. On the other hand, the posture when moving from the seat to the tatami mat or to the bed is inconvenient for the key type or the L type. Especially when moving to a bed, there is a risk of falling from the bed. For example, the V type does not have such a possibility (details will be described in the text). In other words, the body holder used in this device must change depending on the situation of use. That is, the fourth issue is the development of such a body holder. 5. The effort of the caregiver when attaching and detaching the body holder to the physically handicapped person is small.

[0004]

[Means for Solving the Problems]

1. The first problem, that is, the equilibrium by suspending a disabled person on the arm protruding toward the front of the device, is solved by engaging a weight balance wheel at the rear part of the device. Alternatively, a caregiver rides in place of the weight balance car. 2. The second problem is solved as follows. This device raises and lowers a handicapped person suspended on the tip of the protruding arm and moves it back and forth along the protruding arm. When this operation is performed, the movement by the device is stopped, the device is locked to the floor, and the caregiver assists, so there is no instability. On the other hand, the movement of the device is performed in a state where the physically handicapped person is sitting on the seat, so that the device is similar to a known wheelchair and there is no risk of falling. In addition, the device has a small size because it has a mechanism that shrinks all the protruding parts, which enables bathing in a small bathroom, for example. 3. By using the mechanism for raising and lowering the handicapped that is built into this device, the swash plate installed at the step can be moved up and down,
It made it possible to cross a large step with a small amount of care by the caregiver. 4. It is necessary for the handicapped person to have a different posture, for example, when moving from a tatami mat or from a bed to a seat, and vice versa. However, one-touch operation on the body holder enables necessary conversion. 5. Using the mechanism to move the handicapped person up and down, the body holder was easily attached and detached.

[0007]

The operation of the mechanism relating to the handle 35 will be described. The caregiver turns the handle to move the handicapped person mounted on the carrier 29 back and forth, but when the caregiver is releasing his / her hand from the handle, if some external force is applied to the suspended handicapped person carelessly, the handicapped person will fall on the horizontal pillar. In particular, there is a risk that it may start moving toward the tip of the horizontal column. The mechanism associated with the handle prevents that. That is, when the assistant releases the handle pipe 40, the lock rod 44 is fitted into the lock hole of the lock plate 46 fixed to the head due to the compression spring 45, and the rotation of the handle is stopped. When the caregiver rotates the handle, the compression spring 45 is rotated while being compressed. Next, the operation of the mechanism of the rotating horizontal column will be described. The horizontal column is rotated by a hinge. At this time, the front and rear chains change the direction by 180 degrees along the hinge joint, so that the sprocket 33 and the tip pulley 34 are rotated together.
The interval of will shrink. Also, when the rotating horizontal column that is turned 180 degrees is extended in a straight line, the distance between the sub rocket and the tip pulley increases with rotation. The configuration of the device allows this to be done smoothly. The operation of the lock ring 61 and the compression spring 62 relates to the safety of this device. In this device, it is dangerous to turn the handle 59 upward along the groove 63 when the hanger 84 is under load. This mechanism prevents inadvertent operation. That is, the notch 60 engraved on the locking ring
Therefore, if you do not push the knob 52 to the left with your finger,
Do not leave 3. Next, the action based on the mechanism for extending and contracting the vertical column will be described. In FIG. 4, the vertical column is located at the center of the handle shaft 95, and the caregiver presses the handle shaft with one hand and the handle pipe 96 with the other hand against the vertical column. The middle diameter of the handle shaft is smaller than the width of the widening hole and larger than the width of the vertical groove. Therefore, if that portion is inserted into the widening hole, the upper vertical column and the lower vertical column are fixed. Let's eat one side. Then, tighten the knob nut 97. Since the device has three widening holes, the height of the device can be changed in five steps. Ie 17
0 cm, 150 cm normal (when height is especially required) and 120 cm (when riding a car). Further, if the vertical column adjustment handle is moved to the bottom of the vertical groove provided in the vertical column receiver 10, it becomes 100 cm, and the head is attached and detached at this height. Also, if you remove the head, it will be 80 cm, which is the height when you substitute for a wheelchair. Next, based on FIG. 5, the belt detachment prevention device 7
Write 8. The belt disengagement preventer is swingable with respect to the hook 77 because of the fulcrum 79. Because of the stopper 83, it does not rotate to the right from the position shown in the figure, and because of the stopper 82, it does not rotate to the left about 45 degrees or more from the position shown. Further, because of the tail portion 81, the position shown in FIG. 5 is always kept. Therefore, the belt can enter the hook by pushing the claw 80, but cannot exit the belt unless the caregiver raises the tail portion 81 upward. Next, the operation of the oil adhesion preventing cylinder 85 of FIG. 1 will be described. When the disabled person is lifted and the posture of the disabled person is a key type described below, the hanger pulley 70 may approach the face of the disabled person and the hanger pulley and the load chain immediately above may contact the face. At that time, the chain lubricating oil adheres to the face. The oil adhesion prevention cylinder covers the chain to prevent oil adhesion. When the hanger rises and approaches the horizontal pillar, the oil adhesion prevention cylinder closes, but when the hanger lowers, it is restored by the restoring force of the coil spring. The ring 88 prevents the upper part of the oil adhesion preventing cylinder from getting into the groove of the hanger rail. The balance when the horizontal pillar is extended and the disabled person is suspended at the tip of the horizontal pillar may be achieved by engaging the weight balance wheel with the rear balance weight support plate 14 as described above. When the handicapped person moves ahead of the arm and the device tilts, the central portion of the rear balance weight support plate pushes the center of gravity of the weight balance vehicle. Next, the operation of the caregiver lifting the handicapped person with respect to the body holder will be described. The caregiver lifts the disabled person's head and puts the back belt 143 under the head. The chain 141 is placed between the disabled arm and chest, and the connector 142 is operated to disconnect the chain from the knee belt. Lift the ankle one side at a time and put the knee belt in the proper position on the thigh (the proper position depends on the person's upper back etc.), and connect the shin tape under the knee as shown at 150 in FIG. 14 (a). , Make sure the knee belt does not shift from its proper position. Operate the coupler to connect the chain to the knee belt. Hang the hook on the hanger as close to the side of the chain as possible. When the armpit enters the side of the handicapped person and the specific chain described below appears between the chest and arm, lower the hanger and hang the hook on the specific chain. At this time, the hanger direction display mark on the hanger pulley 70 should face the handicapped person. When a person with a physical disability is lifted, the person with a physical disability turns their back toward the seat, so if you pull it down with the handle, you can sit on the seat.
When the handicapped person is lifted up and the armpit belt is likely to move to the back due to small friction of clothes, the vertical column tape 144 and the chain 141 are connected with the auxiliary tape 146. The posture of a person with a disability when suspended depends on the position of the chain. When the position of the chain is close to the knee belt, the posture of the handicapped person is shown in Fig. 14 (a).
It is called a key type. It is called V-shaped, which is (c) in the vicinity of the middle between the side belt and the knee belt. After making the posture of the handicapped person into a key shape, attach the ankle tape 1 of Fig. 9 to the ankle of the handicapped person.
55, hook the ring 162, pull up the loop 153 with one hand and pull the free end 160 with the other hand.
Is pulled to obtain the L shape shown in FIG. If the belt adjuster 159 is pushed in the direction of the arrow, the belt becomes loose and becomes a key shape. Now, a person with a disability needs a key shape or an L shape in order to get on the seat of the present apparatus, a seat of a wheelchair, or the like, and a V shape is necessary for getting on a tatami mat or a bed. For example, in the case of the key type or the L type, as shown in FIG. 14, in the case of a bed in which the lying direction is not fixed after a part of the body comes into contact, there is a risk of falling from the bed. Also, the distance d that the head separates from the contact point while lying down is large in (a) and (b) and small in (c), and in (c), the direction in which the head falls after the contact with a part of the body. It is fixed. It is necessary to have an L-shaped posture and the height of the horizontally extended legs to be higher than the height of the bathtub. Further, if the chain is hooked at two places at the same time, the main belt 136 is shortened, and this state is necessary when the disabled person is transferred from the apparatus to the seat of the automobile. That is, it is not necessary to prepare various belts such as L, M, and S. In addition, when moving to the seat of the automobile, the physically handicapped person needs to sit sideways on the seat of this device. To remove the belt from the handicapped, hang it up and hang it over both ends of one of the chains. The disabled will turn sideways and the belt will eventually come off.
The sideways position is convenient for the caregiver to wipe the body. Next, the auxiliary belt of FIG. 11 will be described. When putting a belt on the lower half of the handicapped person, it may be difficult for the knee belt to get under the knee depending on the condition of the foot. In such a case, rotate one end of the auxiliary belt under the knee and rotate the rings 173 and 175.
You can easily put on the knee belt by hooking on the hook and lifting your foot to an appropriate height. Next, in order for the device to pass over the protrusion of about 6 cm or less, the caregiver grasps the handle 35 with the right hand and the step bar 65 with the left hand in FIG. 2 and pulls one foot on the balance weight receiving plate 17 to push the front wheel. Over. The rear wheels are relatively easy to cross if they are not inflated with a large diameter. Next, referring to FIG. 12, a situation where a large step is crossed will be described. The swash plate 177 is applied to the step, and the pulley 182, the support square pipe 179, and the pulley 1
83 is mounted as shown in FIG. The caregiver removes the chain hook 69 at the tip of the load chain from the chain support rod 67,
The load chain is applied as shown in FIG. Pulley 18 at fulcrum 181
2 and Chien hook 69 are attached. The helper puts the hand chain 7
If you pull 5, the device will climb the swashplate. When descending, it descends in the posture shown in FIG. The chain hook 69 is the fulcrum 1
When the pulley 183 is removed from the circular ring 180 and the chain hook is hung on the circular ring from 81, the weight of the hand chain doubles but the speed doubles. If a fulcrum 184 is provided on the step (a hotel in the future, etc.), the supporting angle pipe is unnecessary and another rope may be added.

The object of the present invention is to solve the problems associated with various kinds of assistance for persons with disabilities as much as possible and to reduce the burden on the assistant. (1) Regarding the burden of attaching a body support tool to a physically handicapped person, the helper's effort is the burden of lifting the head and ankle of the physically handicapped person one side at a time, and the other heavy burden is taken by the chain block. The chain block will be responsible for all disengagement of body retainers. It is easy to change clothes such as underwear by raising the upper half of the body with a side belt, sitting on the bedding, and hanging halfway. (2) Next, the case where the bedding on the tatami mat is transferred to this device will be described. With respect to the inclination of the present device that occurs when a person with a disability is suspended at the end of a horizontal pillar protruding from the device placed beside the bedding, the present device is provided with a preventive means at the rear portion of the device. This will be described below. (A) In FIG. 15, the counterclockwise moment generated by suspending the disabled person at the end of the horizontal column is M _L , and the weight W of the disabled person is
₁ , and letting a be the distance between the contact point P between the front wheel and the floor and the direction of gravity due to W ₁ , then M _L = aW ₁ . A clockwise moment centered on P is W _R , a force W ₂ that the rear wheels push on the floor based on the weight of the device, a distance b between the front wheels and the rear wheels, and M _L provided at the rear of the device. Letting W ₃ be the equivalent load obtained by the means for canceling, and c be the distance between the directions of P and W ₃ , then M _R = bW ₂ + cW ₃ , and when this device is in the equilibrium state, W _L = _{W R,} hence the _{aW 1 = bW 2 + cW 3} . It is desirable that the self-weight W _{2 of} this device be as small as possible. Also, if C is increased from this equation, W ₃ may be small, but since this device is intended for use in a small bathroom, b and c are limited and the size of W ₃ is limited. Settled. In this device, a = 44 cm, b = 45 cm,
c = 65cm Of the weight of the device _{W 2} Haoumune 2
It is 5 kg. If W ₁ = 100 kg, W _{3 is} 50
It becomes kg. Means for sell equivalent load W ₃ to offset (b) M _L, for example Toka method that does not require W ₃ and W ₂ is sufficiently large, the fulcrum on the floor of the rear vicinity of the device Although there is a method of providing the present apparatus and connecting it to the apparatus, the former method is disadvantageous in that the weight of the entire apparatus becomes large and, for example, a tatami mat in a house or a step is exceeded. The latter is also uncommon. The following three methods will be compared below. A weight to be placed on the balance weight receiving plate 17 is prepared in advance, and an assistant can place it on the support when necessary. The weight of the weight is W ₁ = 1 as described above.
If the weight is 00 kg, the weight will be 50 kg, and it will be a considerable burden on the caregiver to raise or lower this weight each time. For example, if the caregiver weighs 40 kg, 10 kg is always placed on the balance weight support plate, and the caregiver rests when necessary. Although this method is less burdensome to the caregiver, it has the drawback that the disabled person cannot separate from the balance weight support plate while he is at the end of the horizontal column. This does not allow the caregiver to provide sufficient care, for example, when taking a bath. In addition, there is a risk of falling when separated. In other words, this method has a drawback that the caregiver is not burdened sufficiently, but cannot be sufficiently assisted. However, if this method is used well, it is often possible to exert a sufficient effect of assistance. A method of preparing a weight balance wheel having a necessary weight and engaging the weight balance plate when necessary. The reason for this is that there is almost no burden on the caregiver, but the reason is as follows. (A) It is not always necessary to mount the required W ₃ on the balance weight support plate. That is, when the physically handicapped person advances in front of the horizontal column, this device tilts and the balance weight support plate rises. On the other hand, if an object having a weight of W ₃ is placed close to the balance weight receiving plate, after the two come into contact with each other, the lifting of the balance weight receiving plate stops. (B) Even if it takes a heavy load to move W ₃ up and down, the movement in the horizontal direction is light and does not become a burden because of the wheels.
That is, the caregiver may move the weight balance wheel onto the balance weight support plate. As described above, after the weight balance wheel is moved, the device main body and the weight balance wheel may be closely attached or coupled with each other by screws or the like. (Changing between connection and disconnection must be easy. You can't enter a narrow space until the connection and you can't go over small steps.) Since it is possible to move up and down, this method results in a small burden on the caregiver and sufficient care. (3) Since all movements of the handicapped person by this device are performed when the handicapped person is sitting, they do not fall down during the movement.
Further, since the person with disabilities can be connected to the column by the column tape 144, the body will not collapse during the movement. In addition, the vertical movement of the physically handicapped person is not accompanied by the front-back movement, so that the movement becomes stable. (4) Since this device has a mechanism of contracting the protruding portion, it can be used even in a narrow place. (5) For example, a person with a physical disability needs a key shape to move from the bed to the apparatus, and a V-shape is required to move from the apparatus to the bed.
Although a mold is required, since the belt contains chains, it can be done with almost one-touch operation, such as replacing hooks with chains. Moreover, it is easy to change the length of the belt according to the height of the handicapped person, and it becomes possible to ride in a car.
An L-shaped belt is required for bathing in a small bathroom, but this is easy with an ankle belt. (6) A small step can be performed by a simple operation, and a large step can be overcome with a small amount of labor by a caregiver by using a swash plate prepared separately from the chain block incorporated in this device. (7) The main body of the device can be divided into a vertical column and a trolley, which can be accommodated in the trunk of an automobile. Therefore, people with disabilities can go out and stay overnight with their family in their own car. (8) Depending on the purpose and place of use, this device does not require expansion or contraction of the horizontal or vertical columns. Further, the weight balance weight 133 may be placed on the rear portion of the carriage 5. The device is simple and therefore inexpensive. (9) It is possible to add a drive device using an internal combustion engine or electric power to this device so that not only the movement but also the forward / backward and vertical movements can be performed by the switch at hand.
