I have.

  The drive means includes a base 18, a motor 12 housed in the base 18, and an actuator 14 that protrudes above and below the base 18 by the rotation of the motor 12. The control device 10 is composed of an electronic circuit such as a microcomputer, and controls the operation of the bathing lift device 1 using built-in software. Specifically, the control device 10 is connected to a motor 12, a sensor 20, and a switch (not shown) provided on a grip 22 described later. The control device 10 is stored in the base 18. The control device 10 is not limited to the one that realizes the control operation by software, and may be realized only by hardware such as a logic circuit.

  The seat 16 has a seat-like shape and is a structure in which the cared person 6 can sit. The upper back portion of the back portion of the seat portion 16 protrudes rearward and is connected to the upper end of the actuator 14 so as to be rotatable in the horizontal direction. The seat 16 has a structure that allows the caregiver 8 to attach the hand or body of the caregiver 8 while the care receiver 6 is sitting. More specifically, the caregiver 8 holds the seat 16. Or it is a structure which can be gripped. A sensor 20 is provided on the back portion of the seat 16. The sensor 20 is provided in a portion where the caregiver 8 attaches a hand, and detects an operation force for the caregiver 8 to operate the seat portion 16. The seat 16 can be provided with a reclining function so that the cared person 6 can easily take a bath.

  Further, a grip 22 that can be gripped by the caregiver 8 is provided on the back portion of the seat portion 16. By providing the sensor 20 and the grip 22 at a position where the caregiver 8 of the backrest portion of the seat 16 can touch and operate simultaneously, one hand of the caregiver 8 becomes free. Become. Considering that the caregiver 8 operates by gripping the grip 22, for example, the sensor 20 is provided on the grip 22, and the caregiver 8 detects the operation force that supports the grip 22 by the sensor 20. preferable. In the present embodiment, the following description of the present embodiment and the description of the drawings are performed on the assumption that a device in which the sensor 20 and the grip 22 are integrated is used. That is, the sensor 20 detects a force that the caregiver 8 tries to lift the grip 22 or pushes down the grip 22 as an operation force. The grip 22 is provided with a switch (not shown) for switching ON / OFF of the entire apparatus, but it is not always necessary.

  As shown in FIG. 1, the positional relationship between the bathtub 4 and the bath lift apparatus 1 is such that the seat 16 can enter and exit the bathtub 4 with the actuator 14 moving up and down, and the cared person 6 This is a position where the cared person can take a bath while sitting. In consideration of the case where the cared person 6 first sits on the seat 16, the lift 16 for bathing can be moved to a position where the seat 16 can be lifted and removed from the bathtub 4 by turning the seat 16 in the horizontal direction. Need to be placed. In the present embodiment, the bath lift apparatus 1 and the bathtub 4 are described as separate bodies. However, the present invention is not limited to separate bodies, and the base 18 of the bath lift apparatus 1 is not limited thereto. It is also possible to integrally form the bathtub 4.

  Next, operation | movement of the lift apparatus 1 for bathing of this Embodiment is demonstrated. First, the cared person 6 is caused to sit on the seat 16 by being lowered from the bathtub 4. Next, the caregiver 8 holds the grip 22 with the other hand while attaching one hand to the care receiver 6 or the seat 16 (see FIGS. 2 and 3A). When the caregiver 8 turns on the switch of the grip 22, the control device 10 operates the bath lift device 1. As an actual operation, first, the caregiver 8 lifts up so as to hold the seat 16 in a state where the cared person 6 is seated, but the force to lift the grip 22 of the caregiver 8 is increased. The care device 8 can be operated by the care receiver 8 or the seat 16 in accordance with an operation force detected by the sensor 20 as the operation force detection means and below the predetermined operation force detected by the sensor 20. The motor 14 is controlled to raise the actuator 14. That is, the actuator 14 rises while compensating for the effort to lift the cared person 6 including the care receiver 8 including the seat 16.

  When the seat 16 and the cared person 6 reach a height at which the seat 16 and the cared person 6 can turn in the horizontal direction on the bathtub 4, the lift stops if the switch of the grip 22 is turned off. Then, as indicated by the horizontal arrows in FIG. 2, the caregiver 8 turns the care receiver 6 together with the seat 16 in the horizontal direction, and moves the seat 16 and the care receiver 6 above the bathtub 4. (See FIG. 3 (a)).

  Then, when the switch of the grip 22 is turned on while removing the force to support the grip 22, this time, the control device 10 causes the caregiver 8 to take care of the care recipient 6 or the seat according to the operation force detected by the sensor 20. The motor 12 is controlled to lower the actuator 14 so that the force for supporting the portion 16 is below a predetermined value. Then, when the seat 16 is lowered, the cared person 6 is immersed in the hot water Y of the bathtub 4 while the caregiver 8 is holding the seat 16 and the cared person 6 (see FIG. 3 (b)). Then, in a state where the cared person 6 is sufficiently immersed in the hot water Y, the caregiver 8 turns off the switch of the grip 22, whereby the operation of the actuator 14 is stopped and the bathed state of the cared person 6 is maintained.

When the care recipient 6 has finished bathing, the caregiver 8 turns on the switch of the grip 22 as shown in FIG. The force to pull up the grip 22 of the caregiver 8 and lift the seat 16 and the cared person 6 is detected by the sensor 20 that is the operation force detection means, and the control device 10 detects the force below the predetermined value detected by the sensor 20. In response to the operating force, the motor 12 is controlled to raise the actuator 14 so that the caregiver 8 can operate the care receiver 6 and the seat 16.
That is, the actuator 14 rises while compensating for the effort to lift the cared person 6 including the care receiver 8 including the seat 16. Then, the cared person 6 goes up from the hot water Y (FIG. 3A).

  If the seat 16 and the cared person 6 reach a height at which the seat 16 and the cared person 6 can turn in the horizontal direction on the bathtub 4, the lift of the grip 22 stops if the switch of the grip 22 is turned off. Then, as indicated by the horizontal arrow in FIG. 2, the caregiver 8 pivots the cared person 6 together with the seat part 16 in the horizontal direction so that the seat part 16 and the cared person 6 are removed from the bathtub 4. Move. Then, the seat 16 and the cared person 6 are lowered by the same operation as when the seat 16 and the cared person 6 are lowered in the bathtub 4, the operation of the seat part 16 is stopped, and the cared person 6 is seated. Remove from section 16 and bathing ends.

As described above, according to the bathing lift device 1 of the present embodiment, the caregiver 8 is in the state where the caregiver 8 is attached to the seat 16 in the state where the cared person 6 is sitting, and the carer is driven by the driving means. The caregiver 8 bathes the cared person 6 by immersing it in the hot water Y of the bathtub 4 while holding the cared person 6 together with the seat 16 while supplementing the labor of 8 It is possible to reduce the sense of leaving the person only to the machine of the person 6 and to suppress the feeling of anxiety of the cared person 6, and to suppress the feeling of anxiety, the speed of bathing can be increased.

  In addition, since the caregiver 8 can hold or hold the seat 16, the caregiver 6 can easily feel that the caregiver 6 is directly supported by the caregiver 8. Anxiety can be suppressed.

  Further, the control device 10 as the control means drives the care means 8 so that the caregiver 8 can operate the care receiver 6 and the seat portion 16 according to the predetermined or less operating force detected by the sensor 20 as the operation force detection means. By controlling the above, the seat 16 can be easily operated while reducing the labor of the caregiver 8 without being aware of the weight of the cared person 6 and the buoyancy in the hot water Y.

  The control of the raising / lowering speed of the seat portion 16 will be described with reference to FIGS. In the following description of the present embodiment, the reference numerals in parentheses correspond to the reference numerals in FIG. First, when the bathing lift device 1 (control device 10) is turned on (S100), the control device 10 reads various setting information and sets the standby state (S102). Next, the control device 10 checks whether or not the switch of the grip 22 is turned on (S104).

  In a state where the switch of the grip 22 is not turned on (S104-NO), the control device 10 sets the value of the sensor 20 to 0 and performs impedance calculation to output to a routine (S130, S132) for generating a speed command (S120). . The output of the sensor 20 output to the routine (S132) for performing impedance calculation in the control device 10 (S130) and generating a speed command varies depending on the force applied to the sensor 20. Specifically, the output is as shown in the graph of FIG. As shown in FIG. 5, when the applied force is smaller than Xa (−Xa), it is determined that there is no output from the sensor 20 (S106—NO), and 0 is output (S120). When the force applied to the sensor 20 exceeds this value, a signal output is output. However, if the applied force exceeds a certain value, the signal output becomes an upper limit fixed value beyond that, and if a larger force is applied, the control device 10 assumes that the output of the sensor 20 is overloaded (S108-YES). 0 is output (S120). In FIG. 5, the left and right sides of the X-axis are divided into an operating force for lifting the grip 22 and an operating force for lowering.

  Next, when the sensor 20 is not overloaded (S108-NO), the control device 10 checks whether the upper limit switch of the actuator 14 (not shown) is the mechanical upper limit (S110). Here, if the upper limit has been reached (S110-YES), if the sensor 20 is applied with an operation force for obtaining an upward motion, 0 is output to the routine for impedance calculation (S130) and vice versa. If a downward movement is required, a signal output is output (S122).

  When the mechanical upper limit is not reached (S110-NO), the control device 10 confirms whether or not the mechanical lower limit is reached by a lower limit switch of the actuator 14 (not shown) (S112). Here, if the lower limit has been reached (S112-YES), if the sensor 20 is applied with an operation force for obtaining a downward motion, 0 is output to the routine for impedance calculation (S130) and vice versa. If an upward movement is required, a signal output is output (S124).

  Furthermore, when the mechanical lower limit has not been reached (S112—NO), the control device 10 outputs a signal output to a routine (S130) for calculating impedance (S126). A routine for generating a speed command (S132) determines the operating speed of the actuator 14.

  As described above, the control means 10 controls the drive speed of the seat portion 16 according to the operation force detected by the sensor 20 which is the operation force detection means. Therefore, it is easy to reflect the movement of the car caregiver, the mechanical movement is suppressed, and a more faithful operation by the caregiver 8 becomes possible.

  Further, the control unit 10 controls the start and stop of the driving of the seat portion 16 in accordance with the operation force detected by the sensor 20 which is the operation force detection unit, so that the caregiver 8 can remove the grip 20 provided with the sensor 20. Control that stops the driving of the seat 16 when the hand is released is possible, and the safety of the cared person 6 can be ensured.

  Furthermore, when the control means 10 overloads the sensor 20, that is, when the operation force is greater than or equal to a predetermined value, the caregiver 8 suddenly operates the grip 22 by controlling the drive means to stop driving the seat portion 16. Control that sometimes stops the driving of the seat 16 is possible, and the safety of the cared person 6 can be ensured.

  In the description of the above embodiment, the grip 22 is provided with a switch (not shown), and the overall start and stop of the drive is determined using ON / OFF of the switch. However, the same function as this switch can be performed using other sensors. Furthermore, a switch and another sensor may be provided together.

  As another sensor, for example, a strain sensor may be provided in the grip 22, and the force with which the caregiver 8 grips the grip 22 may be taken into the control device 10 as a pressing force. FIG. 6 is a flowchart showing the operation of the apparatus in which the grip switch configured by attaching the strain sensor to the grip 22 as another sensor as the pressing force detecting means is shown in FIG. 6, and a graph showing the output of the grip switch is shown in FIG. FIG. The operation will be described below with reference to FIGS. In the following description of the present embodiment, the reference numerals in parentheses correspond to the reference numerals in FIG.

  First, when the bathing lift device 1 (control device 10) is turned on (S200), the control device 10 reads various setting information and sets the standby state (S202). Next, the control device 10 takes in and determines the output of the grip switch. Specifically, the output is as shown in the graph of FIG. As shown in FIG. 7, when the applied force is smaller than Xb, it is considered that the grip switch is not ON (S204-NO), and 0 is output as the value of the sensor 20 (S220). That is, the value below Xb is 0. When the force applied to the grip switch exceeds Xb, a signal output is output as an output. However, when the applied force is equal to or greater than Xb ′ and the grip switch is overloaded (S206—YES), 0 is output as the value of the sensor 20 (S220). Subsequent control (S208-) is the same control as in the above-described embodiment, and thus description thereof is omitted.

  Thus, the caregiver 8 controls the start and stop of the driving of the seat portion 16 according to the pressing force detected by the grip switch as the pressing force detecting means, so that the caregiver 8 can control the grip switch ( Control that the drive of the seat 16 stops when the hand is released from the grip 22) is possible, and the safety of the cared person 6 can be ensured.

  Furthermore, the caregiver 8 grasps the grip switch (grip 22) by detecting the gripping force as the pressing force by the grip switch that is the pressing force detecting means. It can be operated with a grip and is easy to operate. Further, since the caregiver 8 grips the grip switch (grip 22), the caregiver 8 can be securely held even when wet.

  In addition, when caregiver 8 wants to stop driving in an emergency, a case is assumed in which grip switch (grip 22) is gripped strongly. For this reason, when the grip switch (grip 22) is gripped with a force greater than or equal to a predetermined value (S206-YES), it is important to control with the control device 10 so as to stop the driving of the seat portion 16. Since the caregiver 8 will hold the grip switch (grip 22) strongly in an emergency, the pressing force detection means preferably has a grippable shape, and also slips when wet with hot water Y. Since it is difficult, a grippable shape such as the grip 22 is more preferable. Even if the pressing force detection means is not grippable like a grip switch, the control device 10 as the control means controls the driving means to stop the driving of the seat portion 16 when the pressing force is not less than a predetermined value. Thus, for example, when it is desired to stop driving, it is only necessary to strongly press the pressing force detecting means so as to hold the seat 16 strongly, and the driving of the seat 16 can be stopped with a simple operation.

  As described above, it is possible to reduce the sense of leaving care only to the cared person's machine, to reduce the caregiver's anxiety, and to increase the speed of bathing and bathing by suppressing the feeling of anxiety. It is possible to provide a lift device for bathing.
