  The main body 3 includes a housing 16 and an elevating mechanism 12 provided in the housing 16.

  The elevating mechanism 12 is a mechanism that elevates and lowers the central holder portion 2. The direction (path) when the elevating mechanism 12 moves up and down the center holder part 2 is particularly limited as long as it is a direction (path) in which the position of the center holder part 2 changes at least in the vertical direction (vertical direction in this example). It is not something. However, this embodiment demonstrates the case where the raising / lowering mechanism 12 raises / lowers the center holder part 2 along an up-down direction. Moreover, if the structure (structure) of the raising / lowering mechanism 12 is a structure (structure) which can raise / lower the center holder part 2, it will not specifically limit. However, this embodiment demonstrates the case where the raising / lowering mechanism 12 is comprised as follows.

  That is, the lifting mechanism 12 includes a motor M1 (corresponding to a first motor), a connecting portion C1, and a lifting portion 22.

  The motor M1 generates a driving force for moving the center holder portion 2 up and down along the vertical direction. If this motor M1 is a motor that generates a driving force for raising and lowering the central holder portion 2, a rotary motor that generates a rotational force as the driving force and a linear motor that generates a propulsive force as the driving force. Any of these may be used. However, in this embodiment, a case where the motor M1 is a rotary motor will be described.

  That is, the shaft member SH1 to which the nut member N1 is attached is connected to the output shaft (not shown) of the motor M1 so as to extend in the vertical direction. The shaft member SH1 rotates with the rotation of the output shaft of the motor M1. The nut member N1 moves linearly along the vertical direction with respect to the shaft member SH1 by the rotation of the shaft member SH1.

The configuration (structure) of the rotation mechanism 23 is not particularly limited as long as it is a configuration (structure) capable of rotating each arm member 4 about the central holder portion 2 as a central axis. However, in this embodiment, the case where the rotation mechanism 23 is configured as follows will be described.

  That is, the rotation mechanism 23 includes a motor M2 (corresponding to a second motor) and a connecting portion C2.

  The motor M2 generates a driving force for rotating the arm members 4 and 4. If the motor M2 is a motor that generates a driving force for rotating the arm members 4 and 4, a rotary motor that generates a rotating force as the driving force, and a propulsive force as the driving force. Any of linear motors may be used. However, in this embodiment, the case where the motor M2 is a rotary motor will be described.

  That is, the shaft member SH2 to which the nut member N2 is attached is connected to the output shaft (not shown) of the motor M2 so as to extend in the vertical direction. The shaft member SH2 rotates with the rotation of the output shaft of the motor M2. The nut member N2 linearly moves along the vertical direction with respect to the shaft member SH2 by the rotation of the shaft member SH2. Note that the combination of the shaft member SH2 and the nut member N2 can be mounted by, for example, a mechanism having a ball spline or a mechanism having a ball screw.

  The connecting portion C2 connects the upper end side of the nut member N2 and each arm member 4 so that each arm member 4 rotates around the central holder portion 2 in synchronization with the linear movement of the nut member N2. In this example, the connecting portion C2 includes a connecting member 16 fitted in a groove 18 provided on the front side of the periphery of the center holder portion 2 on the left side surface of the header portion 21. Then, the coupling portion C2 is synchronized with the linear movement of the nut member N2 so that each arm member 4 rotates about the central holder portion 2 as a central axis when the coupling member 16 slides in the groove 18. The upper end side of member N2 and each arm member 4 are connected.

The central holder part 2 is connected to the front side. The rotation range of each arm member 4 is not limited to the above range.

  The rotation mechanism 24 is a mechanism that rotates each arm member 5 about the central holder portion 2 as a central axis. The configuration (structure) of the rotating mechanism 24 is not particularly limited as long as each arm member 5 can be rotated about the central holder portion 2 as a central axis. However, in the present embodiment, a case where the rotation mechanism 24 is configured in the same manner as the rotation mechanism 23 will be described.

  That is, the rotation mechanism 24 includes a motor M3 (corresponding to a third motor) and a connecting portion C3.

  The motor M3 generates a driving force for rotating the arm members 5 and 5. If the motor M3 is a motor that generates a driving force for rotating the arm members 5 and 5, a rotary motor that generates a rotating force as the driving force and a propulsive force as the driving force are generated. Any of linear motors may be used. However, in this embodiment, the case where the motor M3 is a rotary motor will be described.

  That is, the shaft member SH3 to which the nut member N3 is attached is connected to the output shaft (not shown) of the motor M3 so as to extend in the vertical direction. The shaft member SH3 rotates with the rotation of the output shaft of the motor M3. The nut member N3 linearly moves along the vertical direction with respect to the shaft member SH3 by the rotation of the shaft member SH3. Note that the combination of the shaft member SH3 and the nut member N3 can be mounted by, for example, a mechanism having a ball spline or a mechanism having a ball screw.

  The connecting portion C3 connects the upper end side of the nut member N3 and each arm member 5 so that each arm member 5 rotates around the central holder portion 2 in synchronization with the linear movement of the nut member N3. In this example, the connecting portion C3 includes a connecting member (not shown) fitted in a groove 19 provided on the rear side of the periphery of the center holder portion 2 on the left side surface of the header portion 21. . Then, the connecting portion C3 is synchronized with the linear movement of the nut member N3 so that each arm member 5 rotates about the central holder portion 2 as the connecting member slides in the groove 19 so that the arm member 5 rotates about the central holder portion 2. The upper end side of N3 and each arm member 5 are connected.

  Such a rotation mechanism 24 is capable of rotating each arm member 5 about the central holder portion 2 as a central axis when the connecting member of the connecting portion C3 slides in the groove 19 by driving the motor M3. is there.

This corresponds to the state of being rotated (standing) to the position that is the upper position of the part 2. Further, FIG. 7 corresponds to a state in which each of the arm members 4 and 5 is at a position where the tip end portions 4 a and 5 a are positioned above the central holder portion 2 (standing up).

  In addition, a cushion material 11 is installed on the central holder portion 2 so as to cover the outer periphery of the central holder portion 2 between the arm members 4 and 4 and between the arm members 5 and 5. The cushion material 11 is made of an appropriate material having cushioning properties (impact buffering properties). Note that the cushion material 11 may not be installed in the center holder portion 2.

  In addition, the arm members 4 and 4 and the arm members 5 and 5 include a plurality of sling sheets 6 (see FIG. 8 and the like to be described later) on which the care recipient H is placed and a plurality of them for releasing the locking. A locking portion 7 is installed. Specifically, the locking portion 7 is attached to each arm member 4 at an intermediate position between the proximal end portion 4 b and the distal end portion 4 a and at two locations in the vicinity of the distal end portion 4 a. It is attached at two positions near the middle position between the end portion 5b and the tip portion 5a and in the vicinity of the tip portion 5a. In addition, the attachment position and attachment number of the latching | locking part 7 are not limited to the said position and number. Moreover, the structure (structure) of each latching | locking part 7 will not be specifically limited if it is the structure (structure) which can perform the latching of the sling sheet 6, and the cancellation | release of the said latching. In this embodiment, the case where each latching part 7 is comprised by the hook-shaped hook attached to each arm member 4 and 5 is demonstrated.

  The casing 16 of the main body 3 is provided with a caster portion 8 for moving the transfer assisting device 1 so as to be positioned below the central holder portion 2. In addition, a member for moving the transfer assist device 1, which is different from the caster unit 8, may be installed in the main body unit 3. Moreover, when it is not necessary to move the movement assistance apparatus 1, the member for moving the transfer assistance apparatuses 1, such as the caster part 8, does not need to be installed.

  The caster unit 8 includes a frame 9 and a plurality of wheels 10 and 20.

It is possible to change the posture of the person H. That is, the central holder part 2, the arm members 4 and 4, and the arm members 5 and 5 constitute means for changing the posture of the cared person who is placed on the sling sheet and lifted.

<Operation of transfer assist device>
Next, the operation of the transfer assist device 1 will be described with reference to FIGS. Here, operation | movement of the transfer assistance apparatus 1 at the time of making the care receiver H who lay down on the bed sit on a wheelchair is demonstrated.

  8 to 10, first, the transfer assist device 1 is disposed in the vicinity of the bed B on which the care receiver H is lying (along the front-rear direction in this example). In this example, the transfer assisting apparatus 1 is arranged so that the arm member 4 is on the care receiver H's foot side and the arm member 5 is on the care receiver H head side. Thereafter, the transfer assisting device 1 rotates both the front and rear arm members 4 and 5 to appropriate positions where the front end portions 4a and 5a are positioned below the horizontal direction of the central holder portion 2, The center holder part 2 is raised in a state in which the sling sheet 6 on which the care recipient H in the posture is placed is locked by the locking parts 7. Thereby, the transfer assistance apparatus 1 lifts the care receiver H in the lying posture from the bed B (see FIG. 8).

  Then, the transfer assist device 1 moves to a predetermined position in a state where the care receiver H in the lying position is lifted, and the distal end portion 5a is centered on the arm member 5 on the rear side (the head side of the care receiver H). Rotate (stand up) to an appropriate position above the holder part 2. Thereby, the transfer assistance apparatus 1 changes the posture of the care receiver H in the lying posture to the sitting posture when sitting on the wheelchair W (see FIG. 9). At this time, the transfer assist device 1 may adjust the posture of the cared person H by appropriately rotating the arm member 4 on the front side (foot side of the cared person H).

  Thereafter, the transfer assist device 1 lowers the center holder portion 2 in a state where the care receiver H in the sitting position is lifted. Thereby, the transfer assistance apparatus 1 makes the cared person H of the sitting position drop down, and makes it sit on the wheelchair W (refer FIG. 10).

  The operation content of the transfer assist device 1 described above is merely an example, and it is needless to say that the transfer assist device 1 can perform operations other than the operation details described above. For example, in the above description, the transfer assist device 1 changes the posture of the cared person H after lifting the cared person H, but changes the posture of the cared person H by lifting the cared person H. After that, you may move. In the above description, the case where the transfer assist device 1 assists the transfer from the lying posture to the sitting posture has been described. However, the transfer assist device 1 assists the transfer from the sitting posture to the lying posture, Assistance for transfer from posture to supine posture (position movement, posture change, etc.), assistance for transfer from sitting posture to sitting posture (position movement, posture change, etc.), and other transfer assistance are also possible. Needless to say.

<Effects of this embodiment>
As described above, in the transfer assist device 1 of the present embodiment, the central holder portion 2 and the arm members 4 and 5 provided in pairs are moved up and down by the lifting mechanism 12 provided in the main body portion 3. The arm members 4, 4 rotate around the center holder part 2 as the central axis on the front side of the center holder part 2. The arm members 5 and 5 rotate around the central holder portion 2 as the central axis on the rear side of the central holder portion 2. Each arm member 4, 5 is provided with a plurality of locking portions 7 for locking and unlocking the sling sheet 6.

  In the transfer assisting device 1 configured as described above, for the care receiver H in the lying position, by turning both the arm members 4 and 5 so as to be positioned below the center holder portion 2, It is possible to lock the sling sheet 6 on which the care recipient H in the prone posture is placed. In addition, for the care recipient H in a sitting position, one of the arm members 4 and 5 is rotated so that one of the arm members 4 and 5 is located below the center holder portion 2 and the other is located in an upper position. The sling sheet 6 on which H is placed can be locked. Thus, since it becomes possible to accept the transfer assist device 1 regardless of the posture of the care recipient H, it is not necessary to change the posture of the care receiver H before the transfer, and the burden on the caregiver is reduced. Can do.

  Further, by rotating the arm members 4 and 4 and the arm members 5 and 5, respectively, the posture of the cared person H can be changed to a desired position (for example, the sitting position at the destination) in the state where the cared person H is lifted. It is possible to change to a suitable posture or a posture suitable for various activities to be performed after the transfer. For example, the posture can be a supine posture or a sitting posture, and the hip angle can be finely adjusted in the supine posture, or the forward leaning posture or the backward leaning posture can be set in the sitting posture. Thereby, since the posture change of the care receiver H after the transfer becomes unnecessary, the burden on the care worker can be greatly reduced. In addition, since the cared person H can be changed to a desired posture and can be seated on the wheelchair W or the bed B or the like and laid on the bed B or the like, meals, changing clothes, movement, excretion, conditioning, Daily activities such as bathing (also referred to as ADL (Activities of Daily Living) and daily activities), activities such as work and hobbies can be increased, and the level of social participation can be improved. As a result, the cared person H can be supported independently.

  Furthermore, since it is possible to maintain a posture that matches the body shape and condition of the cared person H, it is possible to reduce the burden on the body of the cared person H (such as compression of the hip and abdomen).

  Further, since the sling sheet 6 is locked by the plurality of locking portions 7 installed on the arm members 4 and 4 and the arm members 5 and 5, the swing due to the pendulum movement that can occur in the lifting type transfer assist device is prevented. Can be prevented. As a result, it is possible to reduce symptoms such as fear and dizziness of the care recipient H.

  In the present embodiment, in particular, the arm members 4 and 4 and the arm members 5 and 5 rotate independently of each other with respect to the central holder portion 2. Thereby, the flexibility of acceptance of the cared person H and the variety of attitude changes of the cared person H can be further increased.

  Further, particularly in the present embodiment, each of the arm members 4 and 5 is such that the tip portions 4 a and 5 a are positioned above the center holder portion 2 from an angle at which the tip portions 4 a and 5 a are positioned below the horizontal direction of the center holder portion 2. It rotates within the range up to the angle. As a result, by turning both the tip portions 4a, 5a of the arm members 4, 5 so as to be in a position below the horizontal direction of the central holder portion 2, it is possible to assume a lying posture. At this time, it is possible to cope with the case where the head of the care recipient H is on either the arm member 4 side or the arm member 5 side. Further, the arm member 4, 5 can be set in a sitting posture by turning one tip portion of the arm members 4, 5 below the horizontal direction of the central holder portion 2 and turning the other tip portion upward. At this time, it is possible to cope with the case where the front direction of the care recipient H is on the arm member 4 side or the arm member 5 side.

  In the present embodiment, the arm members 4 and 5 are particularly curved so that the distal end portions 4a and 5a face upward when the base end portions 4b and 5b are in a posture extending horizontally from the central holder portion 2. The shape is Thereby, it becomes possible to make the sling seat 6 into a shape adapted to the body shape of the cared person H, to prevent the cared person H from slipping during transfer, and to improve the comfort on the sling sheet 6 it can. Further, it is possible to sufficiently form a space for holding the care receiver H below the center holder portion 2.

  In the present embodiment, in particular, the locking portion 7 is located at two positions near the distal end portions 4a and 5a and the intermediate positions of the proximal end portions 4b and 5b and the distal end portions 4a and 5a with respect to the arm members 4 and 5, respectively. It is attached. Thereby, since the sling sheet 6 can be locked in a total of eight places, four places on the upper body side of the care recipient H and four places on the lower body side, the fixation of the sling sheet 6 is strengthened, and the care recipient H's The effect of preventing shaking can be enhanced.

  In the present embodiment, in particular, the caster unit 8 including a plurality of wheels 10 and 20 is installed in the main body unit 3. The caster portion 8 includes a square frame-like frame 9 that is located below the central holder portion 2 and is open to the rear side. Thereby, since the wheelchair W etc. can be smoothly approached under the center holder part 2 from the open side of the flame | frame 9, the convenience can be improved.

  In the present embodiment, in particular, the cushion material 11 is installed on the outer periphery of the central holder portion 2 between the arm members 4 and 4 and between the arm members 5 and 5. As a result, the cared person H can be grasped (clamped) by the central holder part 2 via the cushioning material 11 during the transfer, and the effect of reducing symptoms such as fear and dizziness of the cared person H can be further enhanced.

  In the above embodiment, the motor is individually provided for the raising / lowering operation of the central holder portion 2, the rotating operation of the arm member 4, and the rotating operation of the arm member 5. That is, the motor M1 generates a driving force only for raising and lowering the center holder portion 2, the motor M2 generates a driving force only for rotating the arm member 4, and the motor M3 causes the arm member 5 to move. A driving force was generated only for rotation. However, it is also possible to configure the driving force to be generated by a plurality of motors for each of the above operations. For example, a driving force for raising and lowering the center holder portion 2 may be generated by at least one of the motor M2 and the motor M3 in addition to the motor M1. Further, the driving force for rotating the arm member 4 may be generated by at least one of the motor M1 and the motor M3 in addition to the motor M2. Further, a driving force for rotating the arm member 5 may be generated by at least one of the motor M1 and the motor M2 in addition to the motor M3. In such a case, the apparatus can be miniaturized by optimizing the necessary motor torque and reducing the motor capacity.

  In the above description, “vertical”, “vertical”, “straight line”, “horizontal”, and “coincidence” do not have a strict meaning. In other words, “vertical”, “vertical”, “straight line”, “horizontal” and “coincidence” are acceptable in design and manufacturing tolerances and errors, and are “substantially vertical”, “substantially vertical”, “substantially straight line”. "" Substantially horizontal "and" substantially coincide ".

  In addition to those already described above, the methods according to the above-described embodiments and modifications may be used in appropriate combination.

  In addition, although not illustrated one by one, the above-mentioned embodiment and each modification are implemented with various modifications within a range not departing from the gist thereof.
