The storage unit includes, for example, an arbitrary storage device that can store this program and various types of information used for processing in the control unit 12. The storage device is, for example, a memory. The control unit 12 may be provided at any location on the main body unit 11.

  Specifically, when the CPU executes a program stored in the storage unit, the control unit 12 causes the first wire driving unit 9 and the second wire when the holder 1 is not attached to the care receiver P. The wire drive unit 10 inputs a command to the first wire drive unit 9 and the second wire drive unit 10 so as to pull the main wire 4 and the control wire 5 with a force that balances the weight of the holder 1. Thereby, in order to attach the holder 1 to the care receiver P, when the care receiver P or the caregiver operates the holder 1, the care receiver P and the caregiver hold the holder 1 with a relatively small force. Can be operated.

  When the holder 1 is not operated by the care receiver P or the caregiver, the control unit 12 controls the tension value of the main wire 4 input from the first tension sensor 6 and the second tension sensor 7. The first wire driving unit 9 and the second wire driving unit 10 connect the main wire 4 and the control wire 5 with a force that balances the weight of the holder 1 based on the tension value of the control wire 5 input from Determine if you are pulling. Then, when the tension value input from the first tension sensor 6 and the second tension sensor 7 is smaller than a predetermined value, the control unit 12 determines the first wire driving unit 9 and the second wire driving unit. A command is input to the first wire driving section 9 and the second wire driving section 10 so that the main wire 4 and the control wire 5 are wound by the wire 10. In addition, when the tension value input from the first tension sensor 6 and the second tension sensor 7 is larger than a predetermined value, the control unit 12 performs the first wire driving unit 9 and the second wire driving unit. A command is input to the first wire driving unit 9 and the second wire driving unit 10 so that 10 sends out the main wire 4 and the control wire 5.

  In addition, when the CPU executes the program stored in the storage unit, the control unit 12 causes the posture of the holder 1 (that is, the posture of the care recipient P) after the holder 1 is attached to the care receiver P. So that the first wire driving unit 9 and the second wire driving unit 10 send out and wind up the main wire 4 and the control wire 5 so as to have a desired posture. A command is input to the second wire driving unit 10. Specifically, the control unit 12 inputs a command to the first wire driving unit 9 so that the first wire driving unit 9 pulls the main wire 4 with a force that balances the weight of the care receiver P. At the same time, the control unit 12 instructs the second wire driving unit 10 to send out or wind up the control wire 5 until the second wire driving unit 10 reaches the desired posture of the care recipient P. Enter.

  The control unit 12 determines the posture of the care receiver P based on the angle value of the holder 1 input from the gyro sensor 8. Then, the control unit 12 determines whether or not the care receiver P has a desired posture based on the angle value input from the gyro sensor 8. When the control unit 12 determines that the care receiver P does not have the desired posture, the control wire 5 is used until the second wire driving unit 10 has the desired posture of the care receiver P. A command is input to the second wire driving unit 10 so as to feed or wind the wire.

  Here, the posture desired by the care recipient P is, for example, a forward leaning posture or a backward leaning posture. When the holder 1 is attached to the cared person P and is lifted by the main wire 4 and the control wire 5 or the like, if the object is simply lifted directly above, the cared person P is likely to slide down from the open buttocks of the holder 1. Become. Therefore, the posture of the care receiver P and the holder 1 is set to the forward tilt posture or the backward tilt posture, and the surface (hereinafter referred to as “support surface”) that supports the weight of the care receiver P of the holder 1 is widely used. Thus, it is necessary to secure the holding force of the holder 1.

  In addition, when the CPU executes a program stored in the storage unit, the control unit 12 receives a command from the operation unit 13 after the care recipient P and the holder 1 have the desired postures. If not, the first wire driving unit 9 and the second wire driving unit 10 send and wind the main wire 4 and the control wire 5 to the first wire driving unit 9 and the second wire driving unit 10. A command is input to the first wire driving unit 9 and the second wire driving unit 10 so as to stop the operation. Specifically, the first wire driving unit 9 and the second wire driving unit 10 are controlled by the main wire 4 and the control by making the winch a mechanism without a back drive or applying a brake to the motor that drives the winch. The feeding and winding of the wire 5 can be stopped.

  As shown in FIG. 3, the operation unit 13 is operated by a caregiver or the like, and inputs a command for operating the care lift device 100 to the control unit 12. The operation unit 13 may be provided at any location on the main body unit 11 or may be a remote controller or the like.

  Next, the first wire driving unit 9 and the second wire driving unit 10 send out and wind the main wire 4 and the control wire 5 so that the postures of the care recipient P and the holder 1 become a desired posture. I take it. Specifically, the first wire drive unit 9 pulls the main wire 4 with a force that balances the weight of the care receiver P. At the same time, the second wire driving unit 10 sends out or winds up the control wire 5 until the care receiver P has a desired posture.

In the case of the holder 1 according to the first embodiment, the desired posture of the care recipient P and the holder 1 is a backward tilted posture as shown in FIG. By setting the posture of the holder 1 to the backward inclined posture, the care receiver P can be supported by the back support portion 1A of the holder 1, and the care receiver P can be prevented from slipping off from the buttocks.
Moreover, since the backward tilt angle of the cared person P and the holder 1 varies depending on the physique of the cared person P and the body shape such as the back of the car, the backward tilt angle for each cared person P is stored in the memory of the control unit 12 or the like. Is preferably set in advance.
Further, although the first wire driving unit 9 and the second wire driving unit 10 operate according to the command input from the control unit 12, the first wire driving unit 9 and the second wire driving unit 10 are used. May operate according to a command input by the care receiver P or the caregiver operating the operation unit 13. In this case, the control unit 12 may be omitted.

By setting the posture of the holder 14 to the forward tilted posture, the cared person P can be supported by the body front support portion 14B of the holder 1, and the cared person P can be prevented from slipping off from the buttocks. That is, the holder 14 can be applied to the cared person P who can take a forward tilting posture and has a strong leg strength to some extent.
Further, since the forward tilt angles of the cared person P and the holder 14 vary depending on the physique of the cared person P and the body shape such as the back of the circle, the forward tilt angle of each cared person P is stored in the memory of the control unit 12 or the like. Is preferably set in advance.

  According to the care lift device 100 according to the second embodiment, the same effect as that of the care lift device 100 according to the first embodiment can be obtained, and the back side of the holder 14 is opened. Thus, the holder 14 can be attached to the care receiver P more easily.

  Note that the present invention is not limited to the above-described embodiment, and can be changed as appropriate without departing from the spirit of the present invention. For example, in the lift devices for care 100 and 200 according to the present invention, the first arm 2 and the second arm 3 may be formed from one arm. That is, the lift devices for care 100 and 200 according to the present invention may include the left and right arms. In that case, the arm includes a first guide roller, a second guide roller, a third guide roller, and a fourth guide roller. The first guide roller is rotatably provided at the end of the arm on the holder 1 or 14 side. The second guide roller and the third guide roller are rotatably provided at the end of the arm opposite to the holders 1 and 14 side. The fourth guide roller is rotatably provided at a position closer to the second guide roller and the third guide roller than the center of the arm. Then, either the main wire 4 or the control wire 5 is wound around the first guide roller and the second guide roller. Further, the other of the main wire 4 or the control wire 5 is engaged with the third guide roller and the fourth guide roller. Accordingly, the arm suspends the holders 1 and 14 from above the holders 1 and 14. In this case, since the care lift devices 100 and 200 only need to include two of the arms, the care lift devices 100 and 200 have a simple structure as compared with the case where the first arm 2 and the second arm 3 are provided in total. be able to.

  In the holder 1, the arm support 1C may be omitted. Furthermore, it is needless to say that various types of holding tools that support the care receiver P in a backward tilted posture on the back surface can be applied to the care lift device 100. Similarly, it is needless to say that various types of holding tools that support the care receiver P in a forward tilted posture on the front of the body can be applied to the care lift device 200.
