Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The device according to the present invention is designed to remodel a publicly known wheelchair used by a physically handicapped person (hereinafter referred to as a physically handicapped person) so that a person with a disability can be selected from a bed or a bed on a tatami mat in a Japanese house It is a device that can be put into a domestic bathtub by a caregiver. In addition, by adding a known slow-moving tool to this device, in the event of an emergency such as a fire, the disabled person escapes from the window of a high-rise building and descends while staying on a known wheelchair.

[0002]

2. Description of the Related Art Conventional bathing equipment requires renovation of a house. In other words, rails are installed on the ceiling and people with disabilities are hung and carried, but this work is not easy for ordinary households in Japanese houses. Moreover, there is no device for an emergency person to escape from the window while sitting on a wheelchair.

[0003]

[Problems to be Solved by the Invention]

1. In order to lift a person with a disability to the center of the bathtub in the bathroom washroom, 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 equilibrium (stability) when the physically handicapped person is put in the bathtub. 2 A person with a physical disability must be lifted by the arm to enter the bathtub. On the other hand, when the device reaches the bathroom from the bedding on the tatami mat, it usually passes through a corner of the corridor, etc., so that the size of the device is particularly limited in its bottom area. There is a high risk of falling when a person with a disability is suspended and carried by such a device. That is, the second problem is stability during movement.

[0004]

[Means for Solving the Problems]

1 The first problem is solved by the following two points. The first point is as follows. Equilibrium by suspending the disabled person on the arm protruding in front of the device is solved by placing a weight balance weight on the back of the device. Or, a caregiver rides in place of the weight balance weight. Next, the second point will be described. It is necessary to change the direction of the arm to put the handicapped person in the bathtub. If only the arm is rotated while the device remains the same, the equilibrium is broken. The entire device must rotate in the washroom to maintain balance. The size of the washroom is usually 90c
It is m square. Since this device has a depth of 70 cm and a width of 55 cm, it can be rotated with a diagonal line of 89 cm (if the device itself is made heavier, only the arm can be rotated). 2 The second problem is solved as follows. This device can move a person with a disability suspended above the protruding arm up and down and back and forth along the protruding arm. When this operation is performed, the device is stopped, the wheels are braked, and the caregiver assists, so there is no instability. In addition, this operation allows the handicapped person to sit on the stool installed in the device. Since all movements of the device are carried out while the disabled person is sitting on his / her back, the movement is similar to that of a known wheelchair, and there is no risk of falling.

[0007]

Next, the operation of this device will be described. First, the balance of this device will be described. The hanger 31 moves back and forth along the horizontal pillar while suspending the disabled person. Since the casters 4 are located almost at the tip of the dolly, when the hanger is away from the proper cube, the device has a counterclockwise rotation centering on the contact portion 80 between the casters and the floor, which is mainly based on the weight of the disabled person. A clockwise moment acts based on the moment and the weight of the device. The counterclockwise moment is the largest when the hanger is located at the end of the horizontal column and is not balanced by the weight of the device. In order to make up for it, the required number of weight balance weights 14 are placed on the balance weight installation plate at the rear of the bogie. In the embodiment, the thickness is 2 cm, the width is 20 cm, and the length is 40 c.
It is an iron plate of m and weighs about 12 kg. If 80 kg is needed, 7 pieces will be 14 cm in height. There is no problem with the balance that the weight balance weight is too heavy. Next, the order of bathing a person with a disability using this device is described (the bottom of the bathtub is about 30 cm lower than the washroom). First, the caregiver puts on a pants-type belt for the disabled person sleeping in the bed. Put both feet of the handicapped person in the part 88 of FIG. 7, put one foot out from 89 and the other out from 90, and raise the pants belt from the knee to the crotch. When putting it on the waist
In the vicinity of 1, pull the string 87 upward so that the string 87 faces the upper half of the body and especially the part of the string at the end. Because of the string, the belt portion 86 does not roll up and penetrates between the waist and the bedding of the physically handicapped person. Next, pull 92 strongly as well,
By repeating this alternately, you can easily put on a pants-type belt. Next, the device is brought close to the bed and the rotating horizontal column is extended. Attach the neck belt, armpit belt and knee belt to the hanger. The tip of the horizontal column projects 50 cm from the characteristic cube, while the width of the bed is usually 1 m. Further, since this device is a caster and easily rotates, the end of the lateral column can be positioned right above the waist of the handicapped person. The caregiver operates the portable up / down front / rear switch 69 to fully lower the hanger, hang the two rings of the pant-type belt on the carabiner at both ends of the hanger, and then place the neck belt, armpit belt, and knee belt on the affected area. Call each one. Operate the portable up / down and front / rear switches to lift the disabled person (Fig. 6) and sit on his back while assisting the disabled person by moving backward and downward. Next, turn the rotating horizontal column to fit it into the unique cube and push the push rod to move it to the bathroom. Enter the washroom and rotate the device to orient the horizontal pillar toward the center of the bathtub. At this time, if the handicapped person's foot gets stuck in the bathtub, operate the portable switch to lift it up and turn it. Brake the wheels. Extend the horizontal pillar and operate the portable switch 69 to raise, move forward, and lower the handicapped person to assist them.
Put the handicapped person in hot water. Similarly, move the disabled to the washing area, wash them, and then put them in the bathtub again. After bathing, reverse the above procedure and return to bed.

[0008]

In this device, since the horizontal column is rotated by rotating the device, the balance between the handicapped person and the weight balance weight is not lost. Further, when the device is moved by the push rod, the disabled person sits on his / her back, so that the device is not unstable.

[0009]

Second Embodiment Next, a second embodiment will be described. In the first embodiment, since the weight balance weight is placed on the platform, the entire device becomes heavy. This embodiment improves this point, but on the other hand presents a risk associated with operational error. The method is a method in which an assistant is placed on the balance weight installation plate instead of placing the weight balance weight, and if there is a shortage, a small amount of weight balance weight is placed in advance for the reason described below. The operational inconvenience resulting from this is as follows. The caregiver forgets to ride on the balance weight installation plate and operates the switch, and carelessly exits from the balance weight installation plate when operating on the balance weight installation plate.
In order to prevent this inconvenience from occurring, the following modifications are made.
A portable up / down front / rear switch 69 is fixed to the vertical column near 78 in FIG. In addition, the circumference of this switch box is raised so that it becomes difficult to operate the push button unless the caregiver gets on the balance weight installation plate. Alternatively, a foot switch is provided so that the switch cannot be operated unless an assistant rides on the balance weight installation plate. Further, in order to prevent the balance weight installation plate from being unintentionally removed, one end of the safety rope 94 shown in FIG. 1 is fixed to one of the two hand push rods 6, and the hook 9 is attached to the other end of the rope.
Fix 5 The ring is fixed to the other hand push rod, and the hook 95 is always hooked on the ring. When the caregiver rides on the balance weight installation plate, remove the hook from the ring and ride it, then turn this rope around the waist and hang the hook on the ring. Unless the hook is removed from the ring, it cannot be removed from the balance weight installation plate, preventing accidental removal. However, since the portable switch is necessary when the person with a physical disability is immersed in hot water as described above, the portable up / down switch 79 is placed at the position 70 in FIG. In addition, when the caregiver rides on the balance weight installation plate and drops the disabled person into the bathtub, the weight of the disabled person will be lighter if he / she is immersed in hot water.
When used to a certain extent, it is necessary for the caregiver to assist the handicapped person by moving out of the balance weight installation plate. Therefore, the weight balance weight to be placed on the balance weight installation plate should be determined in consideration of the ease of this operation. When moving from the bathtub to the washroom, it is desirable to put a low chair or a mat in the washroom to protect the handicapped person according to the situation of the handicapped person. FIG. 8 is an electrical wiring diagram of the second embodiment.

[0010]

Third Embodiment Next, a third embodiment will be described. This device is normally used for bathing and for escape in an emergency. FIG. 1 is modified as shown in FIGS. 9 and 10. In this device, the weight of the handicapped person is balanced only by the weight balance weight, and the caregiver does not ride on the balance weight installation plate. Or, in the case of an emergency, a helper rides, but in an emergency, a weight balance weight corresponding to the weight of the helper and the weight of the wheelchair used for escape is placed on the balance weight installation plate. The vertical column 100 and the horizontal column 101 are removed from each other, and the horizontal column is the swing shaft 10.
Allow swinging around 2. As for the horizontal pillar, the support shaft 103 is in contact with the portion of the support shaft 103 to keep the horizontal pillar substantially horizontal. In an emergency, if the caregiver pushes up the horizontal pillar on the left side of the swing shaft 102 in FIG. 9, the protrusion 105 will be bitten by the spring force into the hole formed in the vertical pillar corresponding to the protrusion, and the horizontal pillar will Figure 9 on the vertical column
It locks like a tilt. Remove the sprockets, worms, worm wheels, electromagnetic solenoids, etc. attached to the joints of the horizontal and vertical columns in FIG. 1 and attach them to the dolly as shown in FIG. 106 is a DC motor and a storage battery, 10
7 is a vertical worm, 108 is a vertical worm wheel that meshes with the vertical worm wheel, 109 is a vertical trolley side sprocket fixed to the worm wheel, 110 is a vertical stanchion side sprocket rotatably mounted on the swing shaft 102, and 111 is 109. 11
A vertical roller chain for coupling 0, 112 is a vertical sprocket fixed to the vertical horizontal column side sprocket 110, and 113 is a vertical chain that engages with 112, and operates in the same manner as the vertical chain 30 of FIG. The mechanism for moving the household chain 114 is similar to that of the up / down chain 113, but the front / rear worm 115 includes the electromagnetic solenoid 1
By means of 16, the rotation of the motor is transmitted only when necessary, as in the first embodiment. A hook 118 for suspending the two loosening implements is fixed to the tip of the horizontal column. Although not shown in the figure, the slow-moving tool ring is fixed to the center of the horizontal bar of the hanger used for this, and the upper and lower chains are fixed to it. 1
Reference numeral 19 denotes a switch which is opened when the horizontal column is horizontal, but is closed when the horizontal column is tilted as shown in FIG. This switch is shown by the dotted line 119 in FIGS. Next, the operation of this device will be described. Do in the following order: For wheelchairs that can be used by persons with disabilities when escaping through a window, wear hanger joint belts with rings attached to the left and right armrests in advance. The emergency caregiver carries the wheelchair and the device near the bed, locks the rotating column of the device in alignment, and connects the hook 118 at the tip with two known one-way loosening devices 121, Pull down the carabiner at the end of the descent rope that hangs down from one of them to a place where it can be reached when the horizontal column is tilted. Tilt the horizontal pillar to lock it, and move the device to bring the tip of the horizontal pillar onto the disabled. Put the pants-type belt on the handicapped person, lower the hanger and connect the body holder to the hanger. The handicapped person is lifted and lowered onto a wheelchair, and the tip ring of the hanger coupling belt of the wheelchair is coupled to the carabiner 120 of the hanger. A handicapped person in a wheelchair is lifted up and a carabiner at the end of the rope hanging from the slow-moving tool is connected to the slow-moving tool ring at the center of the hanger. The person with a physical disability is further hung up, and as shown in FIG. The caregiver continues to press the descent button. Since the upper and lower chains are connected to the fulcrum of 46 through the limiter 74 of FIG. 1, the limiter 74 will act and the switch 74 of FIG. 5 will eventually open.
However, since the switch of 119 is closed, the motor continues to rotate without stopping. Since the chain is easily deviated from the fulcrum 46, the chain deviates from the fulcrum and can be disengaged from the vertical sprocket.
At this time, the weight of the disabled person and the wheelchair is applied to the descending rope of the one-way loosening tool, and thereafter, the descending rope is rolled out, and the disabled person gets on the ground. After this, the caregiver descends using the other one-way slow-moving device.

[0011]

[Modification of Mechanism] Next, another example of the mechanism for moving the hanger up and down and back and forth is shown in FIG. Reference numeral 122 is a vertical column, 123 is a horizontal column, and 124 is a moving chain block. Four known pulleys are attached to a known electric chain block so that a carrier rail of the horizontal column can be moved. Reference numeral 125 denotes a vertical chain that engages with the movable chain block 124. One end of the vertical chain hangs down on the hanger 126 and the other end hangs down inside the vertical column. Reference numeral 127 is a front-rear chain, which is engaged with a drive sprocket 128 and a tip sprocket 129, and both ends of the front-rear chain are fixed to a movable chain block. Reference numeral 130 is a worm wheel fixed to a drive sprocket and driven by a motor 131 and a worm 132. 133 is an automatic code winder. The operation of this mechanism is clear. It should be noted that the movement of this device may be driven by a motor or an internal combustion engine without depending on the human power of an assistant.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The device according to the present invention is designed to remodel a publicly known wheelchair used by a physically handicapped person (hereinafter referred to as a physically handicapped person) so that the disabled person can be removed from a bed or bed on a tatami mat in a Japanese house. It is a device that can be put into a domestic bathtub by a caregiver. In addition, by adding a known slow-moving tool to this device, in the event of an emergency such as a fire, the disabled person escapes from the window of a high-rise building and descends while staying on a known wheelchair.

[0002]

2. Description of the Related Art Conventional bathing equipment requires renovation of a house. In other words, rails are installed on the ceiling and people with disabilities are hung and carried, but this work is not easy for ordinary households in Japanese houses. Moreover, there is no device for an emergency person to escape from the window while sitting on a wheelchair.

[0003]

[Problems to be Solved by the Invention] 1. In order to lift a person with a disability to the center of the bathtub in the bathroom washroom, the arm must be projected about 50 cm from the device. This condition causes the device to tip over. That is, the first issue is the equilibrium (stability) when putting a disabled person in a bathtub. 2. In order to enter the bathtub, the handicapped person must be lifted by his arm. On the other hand, when the device reaches the bathroom from the bedding on the tatami mat, it usually passes through a corner of the corridor, etc., so that the size of the device is particularly limited in its bottom area. There is a high risk of falling when a person with a disability is suspended and carried by such a device. That is, the second problem is stability during movement.

[0004]

[Means for Solving the Problem] 1. The first problem is solved by the following two points. The first point is as follows. Equilibrium by suspending the disabled person on the arm protruding in front of the device is solved by placing a weight balance weight on the back of the device. Or, a caregiver rides instead of the weight balance weight. The second point is described below. It is necessary to change the direction of the arm to put the handicapped person in the bathtub. If only the arm is rotated while the device remains the same, the equilibrium is broken. The entire device must rotate in the washroom to maintain balance. The size of the washroom is usually 90c
It is m square. Since this device has a depth of 70 cm and a width of 55 cm, it can rotate with a diagonal line of 89 cm (only the arm can rotate if the device itself is heavy). 2. The second problem is solved as follows. This device can move a person with a disability suspended above the protruding arm up and down and back and forth along the protruding arm. When this operation is performed, the device is stopped, the wheels are braked, and the caregiver assists, so there is no instability. In addition, this operation allows the handicapped person to sit on the stool installed in the device. Since all movements of the device are performed while the disabled person is sitting on his / her back, the movement is similar to that of a known wheelchair, and there is no risk of falling.

[0005]

Next, the operation of this device will be described. First, the balance of this device will be described. The hanger 31 moves back and forth along the horizontal pillar while suspending the disabled person. Since the casters 4 are located almost at the tip of the dolly, when the hanger is away from the proper cube, the device has a counterclockwise rotation centering on the contact portion 80 between the casters and the floor, which is mainly based on the weight of the disabled person. A clockwise moment acts based on the moment and the weight of the device. The counterclockwise moment is greatest when the hanger is located at the end of the horizontal column and is not balanced by the weight of the device. In order to make up for it, the required number of weight balance weights 14 are placed on the balance weight installation plate at the rear of the bogie. In the example, heat 2 cm, width 20 cm, length 4
A 0 cm iron plate weighs about 12 kg. If 80 kg is needed, 7 pieces will be 14 cm in height. There is no problem with the balance that the weight balance weight is too heavy. Next, the order of bathing a physically handicapped person using this apparatus will be described. (The bottom of the bathtub is about 30 cm lower than the wash area). First, the caregiver puts on a pants-type belt for the disabled person sleeping in the bed. Put both feet of the handicapped person in the part 88 of FIG. 7, put one foot out from 89 and the other out from 90, and raise the pants belt from the knee to the crotch. When putting it on the waist, the caregiver pulls strongly toward the upper part of the belt portion 86 so that the string 87 faces the upper half of the body and particularly the string portion at the end. Because of the string, the belt portion 86 does not roll up and penetrates between the waist and the bedding of the physically handicapped person. Next, pull 92 strongly similarly, and by repeating this alternately, the pant-type belt can be easily worn. Next, the device is brought close to the bed and the rotating cross column is extended, and the neck belt, the side belt and the knee belt are connected to the hanger. The tip of the horizontal column is 5 from the unique cube
It projects 0 cm and the width of the bed is usually 1 m. Further, since this device is a caster and easily rotates, the end of the lateral column can be positioned right above the waist of the handicapped person. The caregiver operates the portable up / down front / rear switch 69 to fully lower the hanger, hang the two rings of the pant-type belt on the carabiner at both ends of the hanger, and then place the neck belt, armpit belt, and knee belt on the affected area. Call each one. The handicapped person is lifted by operating the portable up / down front / rear switch (Fig. 6). Next, turn the rotating horizontal column to fit it into the unique cube and push the push rod to move it to the bathroom. Enter the washroom and rotate the device to orient the horizontal pillar toward the center of the bathtub. At this time, when the foot of the handicapped person touches the bathtub, the portable switch is operated to lift and rotate it by that amount, and the wheels are braked. The horizontal pillar is extended and the portable switch 69 is operated to raise, move forward, and lower the disabled person to assist the disabled person, and to put the disabled person in hot water. Similarly, move the disabled to the washing area, wash them, and then put them in the bathtub again. After bathing, reverse the above procedure and return to bed.

[0008]

In this device, since the horizontal column is rotated by rotating the device, the balance between the handicapped person and the weight balance weight is not lost. Further, when the device is moved by the push rod, the disabled person sits on his / her back, so that the device is not unstable.

[0009]

Second Embodiment Next, a second embodiment will be described. In the first embodiment, since the weight balance weight is placed on the platform, the entire device becomes heavy. This embodiment improves this point, but on the other hand presents a risk associated with operational error. The method is a method in which a helper rides instead of placing the weight balance weight on the balance weight installation plate, and if there is a shortage, a certain amount of weight balance weight is placed in advance for the reason described below. The operational inconvenience resulting from this is as follows. The caregiver forgets to ride on the balance weight installation plate and operates the switch, and carelessly exits from the balance weight installation plate when operating on the balance weight installation plate.
In order to prevent this inconvenience from occurring, the following modifications are made.
A portable up / down front / rear switch 69 is fixed to the vertical column near 78 in FIG. In addition, the circumference of this switch box is raised so that it becomes difficult to operate the push button unless the caregiver gets on the balance weight installation plate. Alternatively, a foot switch is provided to disable the operation of the switch unless an assistant rides on the balance weight installation plate. Further, in order to prevent the operator from inadvertently descending from the balance weight installation plate, one end of the safety rope 94 shown in FIG. 1 is fixed to one of the two push bars 6 and the hook 9 is attached to the other end of the rope.
Fix 5 Attach the ring to the other hand push rod and keep the hook 95 on the ring at all times. When the caregiver gets on the balance weight installation plate, remove the hook from the ring and ride it, then turn this rope around your waist and put the hook on the ring. It is possible to prevent careless removal because the balance weight installation plate cannot be removed unless the hook is removed from the ring. However, since the portable switch is necessary when the person with a physical disability is exposed to hot water as described above, the portable up / down switch 79 is placed at the position 70 in FIG. When a person with a disability gets on a balance weight installation board and puts a person with a disability in the bathtub, the weight of the person with a disability gets lighter. When used to a certain extent, it is necessary for the caregiver to assist the handicapped person by moving out of the balance weight installation plate. Therefore, the weight balance weight to be placed on the balance weight installation plate should be determined in consideration of the ease of this operation. When moving from the bathtub to the washing room, it is desirable to put a low chair or a mat in the washing room according to the situation of the disabled to protect the disabled. FIG. 8 is an electrical wiring diagram of the second embodiment.

[0010]

Third Embodiment Next, a third embodiment will be described. This device is normally used for bathing and for escape in an emergency. FIG. 1 is modified as shown in FIGS. 9 and 10. In this device, the weight of the handicapped person is balanced only by the weight balance weight, and the caregiver does not ride on the balance weight installation plate. Or, in the case of an emergency, a helper rides, but in an emergency, a weight balance weight corresponding to the weight of the helper and the weight of the wheelchair used for escape is placed on the balance weight installation plate. The vertical column 100 and the horizontal column 101 are removed from each other, and the horizontal column is the swing shaft 10.
Allow swinging around 2. As for the horizontal pillar, the support shaft 103 is in contact with the portion of the support shaft 103 to keep the horizontal pillar substantially horizontal. In an emergency, if the caregiver pushes up the left side column of the swing shaft 102 in FIG. 9, the protrusion 105 is pushed into the column corresponding to the protrusion portion by the force of the spring, and the column becomes Lock the column by tilting it as shown in Fig. 9.

The mechanism for moving 4 is similar to that of the vertical chain 113, but the front and rear worms 115 are electromagnetic solenoids 116.
As in the case of the first embodiment, the rotation of the motor is
Tell only when you need it. A hook 118 for suspending the two loosening implements is fixed to the tip of the horizontal column. Although not shown in the figure, the slow-moving tool ring is fixed to the center of the horizontal bar of the hanger used for this, and the upper and lower chains are fixed to it. 119
Is a switch and the horizontal column is open when it is horizontal.
This switch, which is closed when tilted, is shown by the dotted line 119 in FIGS. Next, the operation of this device will be described. Do in the following order: A wheelchair for people with disabilities who want to escape from a window should be fitted with a hanger coupling belt with a ring attached to each of the left and right armrests in advance. The emergency caretaker carries the wheelchair and the device near the bed. Lock the rotating column of this device in a straight line, connect two known one-way slow-moving devices 121 to the hook 118 at the end, and tilt the horizontal column with the carabiner at the end of the descending rope hanging from one of them. When pulling it down to a reach, reach the handicapped person by tilting the lock to lock it and moving the device. Put the pants-type belt on the handicapped person, lower the hanger and connect the body holder to the hanger. The handicapped person is lifted and lowered onto a wheelchair, and the tip ring of the hanger coupling belt of the wheelchair is coupled to the carabiner 120 of the hanger. A carabiner at the end of the rope that hangs up a disabled person in a wheelchair and hangs from the slow-moving device is connected to the slow-moving device ring at the center of the hanger. The person with a physical disability is further hung up, and as shown in FIG. The caregiver continues to press the descent button. The upper and lower chains are the limiter 74 shown in Fig. 1.
Since it is connected to the fulcrum of 46 by means of, the limiter 74 will act and the switch 74 of FIG. 5 will open soon. However, since the switch of 119 is closed, the motor continues to rotate without stopping. Since the chain is easily disengaged from the fulcrum 46, the chain is disengaged from the fulcrum and disengaged from the vertical sprocket. At this time, the weight of the handicapped person and the wheelchair is applied to the descending rope of the one-way loosening device, and thereafter the descending rope is It is taken out and the handicapped gets to the ground. After this, the caregiver descends using the other one-way slow-moving device.
