Next, a description will be given of a method of using the above-described upright assisting device to stand up an assistant who needs to be seated in a wheelchair and hold the upstanding state.
[0033]
First, as shown in FIG. 10, the standing assist device is moved to a predetermined position, and the caster 2 is fixed so as not to move by the fixing function. Next, the wheelchair in which the assistant is seated is moved onto the platform 22, and the wheelchair is brought into contact with the wheel stopper 27 to place the wheelchair at a predetermined position. At this time, the footrest 25 is moved up and down by the vertical movement adjusting means 26 so that the step of the wheelchair does not interfere with the footrest 25. For example, when the footrest 25 is raised, the lever 35 is pulled down to rotate the horizontally arranged rod member 34 in a vertical arc, thereby bringing the rod member 34 into a substantially vertical state. The footrest 25 supported by the rod member 34 rises by the length of the rod member 34. In order to lower the footrest 25, the lever 35 is pushed upward to rotate the rod member 34 in a vertical arc to level the rod member 34.
Next, the first actuator 14 is operated by operating an operation panel (not shown), and the parallel link 9 is rotated in an arc to arrange the pad portion 7 in front of the helper. The caregiver puts both arms on the arm pad 7b, grasps the handle member 10, attaches the body to the pad body 7a, and places the upper body in the pad 7. Next, the side holder 11a and the rear holder 11b are bent inward, and the torso of the person requiring assistance supported by the pad body 7a is fixed by the holder 11. In addition, the feet of the caregiver are replaced on the footrest 25 from the steps of the wheelchair.
[0035]
Next, the first actuator 14 and the second actuator 29 are operated by operating an operation panel (not shown). By operating the first actuator 14, the piston rod 14a reciprocates to push the parallel link mechanism 9 upward. The parallel link mechanism 9 rotates in an arc around the core members 6a and 6b attached to the base end of the support 3 side. The pad portion 7 attached to the tip of the parallel link mechanism 9 moves obliquely upward while maintaining a constant horizontal angle by the circular rotation of the parallel link mechanism 9. The body of the helper who needs to be put on the pad 7 is pushed upward with the movement of the pad 7.
[0036]
By operating the second actuator 29, the piston rod 29a is caused to reciprocate, and the arm member 30 is horizontally rotated about the bending point 30c. The roller 33 attached to the end of the arm member 30 rotates in an arc around the bending point 30c and moves while rotating between the two rectangular rod members 24 provided in parallel. The board 22 provided with the square rod-shaped members 24 moves rearward along the track member 21 shown in FIG. The footrest 25 and the knee pad 41 attached to the base 22 move rearward together with the base 22. The feet of the helper who is pushed upward with the movement of the pad section 7 move rearward together with the footrest 25. In addition, both knees of the helper need contact the knee pad 41.
[0037]
The helper needs to put his / her feet on the footrest 25, his / her knees against the knee pad 41, his / her arms on the arm pads 7b, the hand holding the handle member 10, and the torso in the pad body 7a. It stands up while being fixed by the holder 11. The caregiver attaches and detaches the clothes of the caregiver who stands up, and changes the clothes of the caregiver. After completion of the change of clothes, the first actuator 14 and the second actuator 29 are operated by operating an operation panel (not shown). When the first actuator 14 is operated, the pad section 7 is moved downward, and when the second actuator 29 is operated, the footrest 25 is moved forward, so that the person requiring assistance is seated in a wheelchair.
[0038]
According to the above-described standing assist device, the footrest 25 on which the feet of the helper is moved moves rearward, so that the buttocks of the helper are separated from the seat of the wheelchair, and at the same time, the feet of the helper are centered on the body center of gravity. When the assistant is standing up, the position of the foot of the assistant and the projection point of the center of gravity of the assistant need match. This can reduce the burden on the person who needs help when standing up, and can maintain a stable posture of the person who needs help when the person needs help standing up.
[0039]
In addition, since the footrest 25 can be adjusted up and down, the height of the footrest 25 is adjusted to be lower than the height of the step of the wheelchair when the assistant requiring assistance is sitting on the wheelchair. Thereby, it is possible to prevent a step having a different height depending on the type of the wheelchair from interfering with the footrest 25. Further, the height of the footrest 25 is adjusted according to the body of the person requiring assistance. Thus, it can be used by persons requiring a small body to those requiring a large body.
[0040]
In addition, the upper body of the care-requiring person is fixed to the pad portion 7 while being supported laterally by the side holder 11a and rearward by the rear holder 11b. Thus, even if the assistant requiring help falls down sideways or rearward, the body of the assistant requiring assistance can be supported by the holder 11.
[0041]
Further, since the pad portion 7 and the side holder 11a and the side holder 11a and the rear holder 11b are joined via the one-way clutch 12, the side holder 11a and the rear holder 11b exert a force in a desired bending direction. The angle can be easily adjusted simply by adding. Thereby, the angle of the side holder 11a and the rear holder 11b can be easily adjusted according to the body of the care-requiring person. In addition, when the caretaker needs to put his body on the side holder 11a or the rear holder 11b, the side holder 11a and the rear holder 11b are fixed. This makes it possible to reliably support the person requiring assistance when it falls down.
[0042]
Further, the pad portion 7 supporting the body of the care-requirer forms one side of the parallel link mechanism 9 which rotates in the vertical direction, and moves obliquely upward due to the rotation of the parallel link mechanism 9 in the vertical direction. It moves diagonally upward while maintaining the horizontal angle of. As a result, the body of the care-requiring person assigned to the pad section 7 can move in a stable state.
[0043]
The embodiment of the standing assist device according to the present invention has been described above. However, the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the gist of the present invention. For example, in the present embodiment, the parallel link mechanism 9 is disposed below the central portion of the pad section 7, but the parallel link mechanism 9 is disposed on the side of the pad section 7 to support the pad section 7 in a cantilever manner. You may. By supporting the pad portion 7 in a cantilever manner, the opposite side of the parallel link mechanism 9 with the pad portion 7 interposed therebetween is opened, so that an assistant can easily assist.
[0044]
Further, in the embodiment, the footrest 25 is attached to the platform 22 and the platform 22 is moved backward by moving the platform 22 backward, but only the footrest 25 is moved backward. May be moved.
[0045]
【The invention's effect】
ADVANTAGE OF THE INVENTION According to the standing assistance apparatus which concerns on this invention, a position of a foot of a person requiring help is projection of a body center of gravity of a person requiring help when raising a person who needs help sitting by moving a footrest backward. Since the person moves to the point, the person requiring assistance can be smoothly changed from the sitting state to the standing state. In addition, when the care-requiring person stands up, a stable standing posture can be maintained, and the care-requiring person does not need to support the rear of the care-requiring person, thereby reducing the burden on the care-requiring person and the care-requiring person.
