  The transfer assist device disclosed in Patent Document 2 adjusts the front / rear inclination (pitch), the left / right inclination (roll), and the vertical movement of the base portion by independent driving means. For this reason, there is a problem that the required power required for the pitch adjusting driving means, the roll adjusting driving means and the vertical movement driving means of the base portion is large.

  The present invention has been made to solve the above-described problems, and provides a transfer support apparatus capable of suppressing the necessary power of each driving means for performing pitch adjustment, roll adjustment, and vertical movement of a base portion. For the purpose.

  The transfer support device according to the present invention includes a first base portion having a placement surface on which a cared person's body is placed, and first to first moving each movable body linearly. 3 linear motion mechanisms and each moving body of the first to third linear motion mechanisms is coupled to one end of each of the three linear motion mechanisms and each of the three portions not on the straight line of the first base portion. 1st-3rd link with which an end is couple | bonded. According to such a configuration, the pitch adjustment, roll adjustment, and vertical movement of the base portion can be performed by changing the position of each moving body. In addition, when performing any of these three pitch adjustments, roll adjustments, and vertical movements, the outputs of the three linear motion mechanisms are used. That is, the required power of each linear motion mechanism for performing pitch adjustment, roll adjustment, and vertical movement of the base portion can be suppressed.

  Here, it is preferable that the first to third linear motion mechanisms are arranged so that the moving direction of each moving body is substantially perpendicular to the floor surface. The linear motion mechanism for driving the base portion needs a predetermined length for the moving body to move. Therefore, space saving can be achieved when the linear motion mechanism is installed vertically rather than when the linear motion mechanism is installed with inclination or horizontal displacement.

  The first to third linear motion mechanisms may further include a frame portion having a first strut portion and a second strut portion arranged so as to be spaced apart by a caregiver. The moving direction of each movable body may be arranged substantially parallel to the first supporting column. According to such a structure, when a caregiver transfers a care receiver, a care activity can be performed between the columns, and the degree of freedom of care is improved.

It is preferable that a sixth link is further provided, and the fourth to sixth linear motion mechanisms and the fourth to sixth links are supported by the second support column. According to such a configuration, when the caregiver transfers the cared person, the caring activity can be performed between the support columns, the degree of freedom of care is improved, and the necessary power to support the cared person is obtained. Furthermore, since it can disperse | distribute, the required motive power of each linear_motion | direct_drive mechanism can be suppressed.

  On the other hand, as each moving body of the first to third linear motion mechanisms moves in the same direction along the support column, the first base unit approaches the support column side, and the first It is preferable that the mounting surface of the one base portion is configured to approach parallel to the first support column portion. According to such a configuration, when the transfer assist device is not used, such as when it is moved or stored, the base portion can be brought closer to the support column, and space can be saved.

  Furthermore, it further has an input part for operating at least one displacement of the first or second base part, and the input part has a grip part gripped by a caregiver, and the grip part has a U-shaped cross section. It is preferable to be configured. According to such a configuration, it is easy for the caregiver to hold or release the grip portion, and the degree of freedom of care is improved.

  According to the present invention, it is possible to provide a transfer assist device capable of suppressing the necessary power of each driving means for performing pitch adjustment, roll adjustment, and vertical movement of the base portion.

<Embodiment 1 of the Invention>
FIG. 1 is a perspective view of a transfer support apparatus 10 according to the first embodiment. In FIG. 1, three axes (X axis, Y axis, and Z axis) perpendicular to each other are shown for easy understanding. Here, the XY plane is a horizontal plane parallel to the ground, and the transfer assist device 10 faces the X-axis direction.

  The transfer support device 10 is used in other places such as a wheelchair or a stretcher while supporting a cared person who is sleeping on bedding such as a bed in a hospital, a home, a nursing facility, or the like while lying or waking up. This device is a device for moving the caregiver, and this device lifts the cared person by inserting the base part 13 between the cared person and the bed and lifting the base part 13.

As shown in FIG. 1, the transfer support device 10 includes base portions 13R and 13L on which a cared person's body is placed, an input portion 15 on which operation input is performed, and six linear motion mechanisms 11RR to 11RC and 11LR to. 11LC, a cart unit 17 having a rotatable caster, and a frame unit 16 that supports the linear motion mechanism 11.

Further, the base portion 13R and the mobile bodies 12RR to 12RC are coupled by links 14RR to 14RC. The same applies to the left side in the X-axis direction.
Hereinafter, the linear motion mechanisms 11RR to 11RC and 11LR to 11LC are collectively referred to as the linear motion mechanism 11, and the mobile bodies 12RR to 12RC and 12LR to 12LC are collectively referred to as the mobile body 12 and the base portions 13R and 13L. The base unit 13, the links 14RR to 14RC, and the 14LR to 14LC are collectively referred to as a link 14.

  In this Embodiment, the base part 13 is provided in the both ends of the Y-axis direction in the transfer assistance apparatus 10, respectively, and the upper surface of the base part 13 comprises the surface in which a care receiver is mounted.

The linear motion mechanism 11 and the moving body 12 in this Embodiment are demonstrated. In this embodiment, a ball nut mechanism using a nut as the moving body 12 is disclosed as the linear motion mechanism 11. The ball nut mechanism is roughly composed of a screw part 19, a nut part 20 and a motor 21. The motor 21 rotates the screw part 19 to move the nut part 20 and position the nut part 20.
The linear motion mechanism 11 may be configured as a trapezoidal screw, a cylindrical linear motor, a rack and pinion, or the like instead of the ball nut mechanism as long as it generates linear power. . Moreover, the use in water fields, such as a bathtub, is also possible by making the linear motion mechanism 11 hydraulic.

Further, three linear motion mechanisms 11 are provided for each base portion 13. As shown in FIG. 2, the linear motion mechanism 11 RR and the linear motion mechanism 11 RL are installed at the same height and are held by the frame portion 16. As shown in FIG. 3, the linear motion mechanism 11RC is held in front of the X axis direction between the linear motion mechanism 11RR and the linear motion mechanism 11RL in the Y axis direction. Moreover, as shown in FIG. 2, the linear motion mechanism 11RC is installed above the linear motion mechanism 11RR and the linear motion mechanism 11RL. 2, 3 and 4, the display of the input unit 15 is omitted.
Similarly, the other base portion 13 is also held by three linear motion mechanisms 11.
In the present embodiment, the three linear motion mechanisms 11 and the moving body 12 are provided perpendicular to the floor surface (XY plane). In this case, the space occupied by the apparatus can be reduced.
Note that at least one of the three linear motion mechanisms 11 on the left and right may be arranged non-perpendicularly on the floor surface.

The frame portion 16 supports each linear motion mechanism 11. As shown in FIGS. 1 and 4, the frame portion 16 has a first support column 161, a second support column 162, and an arch portion 163. Each of the linear motion mechanisms 11 is supported by the support columns 161 and 162. Note that the installation height of each linear motion mechanism 11 with respect to the support columns 161 and 162 may be variable because it is determined by the relationship with the height of the seating surface of the bed, wheelchair, or toilet.
In the present embodiment, the support columns 161 and 162 are arranged so as to be spaced apart by a caregiver. The arch part 163 of the frame part 16 forms an arch shape at the upper end of each linear motion mechanism 11. Thereby, in the center surrounded by each support | pillar part 161,162 and the arch part 163, the caregiver can operate the transfer assistance apparatus 10, etc., and has the structure which can pass back from the front and the back from the front. . This structure improves the degree of freedom of care activities in limited spaces in hospitals, homes and care facilities.
In the present embodiment, the frame portion 16 has an arch shape. However, if there is a space where the caregiver can perform a care activity at the center of the transfer support device 10 even if the frame portion 16 is not arched, The degree of freedom is improved. Further, it is not necessary to provide a caregiver's care space at the center of the transfer support device 10. Furthermore, by making the length of the arch part 163 variable, the length between the support pillars 161 and 162 can be changed. As a result, the storability is improved, and it is possible to ensure the degree of caregiving regardless of the cared person's body shape.

  The cart unit 17 is a mechanism for moving the transfer support device 10, and in FIG. 1, four casters are provided and can move freely. The moving means may be a wheel or a caterpillar driven by a motor, or a moving means using other power.

The connection between each base portion 13 and each link 14 will be described. The base portion 13 and the link 14 are rotatably coupled. Since the base portion 13 and the link 14 are rotatably connected, the base portion 13 is configured such that the distance from the floor of each moving body 12, the height difference between the left and right moving bodies 12, or the height of the three-axis moving body. Depending on the difference in height, it can be tilted back and forth and left and right.
For example, the end of the link 14 coupled to the base portion 13 may be configured to be rotatable about the link 14, or the link 14 and the base portion 13 may be coupled with a predetermined clearance. May be provided.

  A coupling portion for each link 14 is provided on the side surface of each base portion 13 on the frame side. The coupling portion of the link 14RC is a convex portion of the base portion 13R and is provided between the link 14RR and the link 14RL. The link 14RR and the link 14RL are both ends of the link 14RC and are coupled to the recess of the base portion 13R. This may be reversed in terms of the unevenness. As described above, the base portion 13 can be displaced to an arbitrary inclination by being coupled at three points on the non-straight line on the base portion 13.

Moreover, in this Embodiment, although each link 14 is supporting each base part 13 from upper direction, you may support at least 1 from the downward direction. When the base portion 13 is supported from below, the care receiver's body such as the link 14 does not interfere with the placement surface of the base portion 13, so that the placement area of the care receiver of the base portion 13 is increased. Is possible.
In the present embodiment, three links are coupled at three points. However, even if four or more links are coupled, the fourth link does not have to interfere with other movements. By connecting with a plurality of links, the strength of the connection is improved.

  The connection between each moving body 12 and each link 14 will be described. Each moving body 12 is provided with a coupling portion of each link. In the present embodiment, the link 14 is coupled to the corresponding moving body 12 by a pin 18 and is coupled so as to be rotatable about a rotation axis parallel to the Y axis in FIG. As a coupling method, it is only necessary that each link 14 can be rotated around a rotational axis parallel to at least the Y axis, and a coupling having another rotational axis may be used. In the present embodiment, each movable body 12 and each link 14 are coupled so that the pin 18 passes through a hole opened in each movable body 12 and each link 14. A cushion member may be interposed between each link 14 and pin 18 or between each moving body 12. In addition, it is not restricted to the said coupling | bonding, You may couple | bond by the ball joint mechanism etc.

The input unit 15 is installed on at least one base unit 13 and is provided at a position where a caregiver who is caring for the care recipient can reach, that is, inside the transfer support device 10. As an input method, a known input device such as a lever, a button, a touch panel, or a joystick can be used.
Further, the input unit 15 as shown in FIG. The input unit 15 includes a gripper 151 and various input devices 152 that are held by an operator. The input device 152 in FIG. 5 is a joystick and is installed toward the inside of the transfer support device 10. A gripping portion 151 at the tip of the input device 152 has a U-shaped cross section. By operating the grip 151 by inserting the palm of the caregiver into the U-shaped depression, the caregiver can easily hold or release the grip 151, and the degree of care is improved. In addition, it is possible to obtain an operational feeling close to that of holding a cared person directly with the palm and holding it.
In this embodiment, the input unit 15 is installed on the base unit 13, but may not be installed on the base unit 13, and the input unit 15 may be installed on the frame unit 16 or a remote control device or the like. Also good.

  Moreover, although not shown in figure, the transfer assistance apparatus 10 which concerns on this Embodiment is provided with the control apparatus. The control device calculates the displacement of each moving body 12 based on the operation input received by the input unit 15. The displacement of the movable body 12 is transmitted to each linear motion mechanism 11 from the calculation result, and each movable body 12 is displaced to an appropriate position using each motor 20.

  The relationship between the movement of the moving body 12 and the base portion 13 will be described with reference to Table 1 and FIG. Table 1 is a relational table of displacements of the moving body 12 and the base portion 13 of each linear motion mechanism 11.

  Here, the base unit 13R, the moving body 12RR, the moving body 12RL, and the moving body 12RC, that is, the mechanism on the right side of the apparatus will be described. When the base portion 13R is simply raised, all the moving bodies are displaced upward at the same time and by the same distance. Each moving body 12, each link 14, and base portion 13 in FIG. 6 are similarly displaced upward in the Z axis. Further, when the base part is simply lowered, all the moving bodies are displaced downward at the same time and by the same distance.

  The forward or backward movement of the base portion 13R can be realized by moving the carriage portion 17 forward or backward.

  Further, when the base portion 13R is tilted to the left, the moving body 12RR is displaced downward, the moving body 12RL is displaced upward, and the moving body 12RC is maintained in a stopped state without being displaced. Thereby, it inclines to the left about the X-axis direction of FIG. 6 as a rotation axis. When tilting the base portion 13R to the right, the base portion 13R is displaced in the reverse direction when tilting to the left.

Furthermore, when the tip of the base portion 13R is raised, the moving body 12RR and the moving body 12RL are kept stopped and the moving body 12RC is displaced downward. As a result, the tip of the base portion 13R is displaced in the Z-axis direction with the moving body 12RR and the straight line connecting the two contacts of the moving body 12RL and the base portion 13R as the rotation axis.
The same inclination can be realized even when the movable body 12RR and the movable body 12RL are displaced upward, and the movable body 12RC is kept stopped.
When the tip end of the base portion 13R is lowered, the tip portion of the base portion 13R is displaced in the reverse direction.
The movement on the left side of the transfer assist device 10 is the same as the movement described above.

In the transfer support apparatus 10 according to the present embodiment, the base unit 13 can be pitch-adjusted, roll-adjusted, and moved up and down by the three linear motion mechanisms 11. As a result, the outputs of the three linear motion mechanisms 11 are used when performing any of pitch adjustment, roll adjustment, and vertical movement. That is, the required output of each linear motion mechanism 11 can be suppressed, and the apparatus itself can be downsized.
Further, the power required to lift the cared person by the base portion 13 is distributed to the three linear motion mechanisms 11. Thereby, since the durability of the linear motion mechanism 11, the link 14, and the frame 16 is not excessively required, the weight can be reduced and the manufacturing cost can be reduced.
In the present embodiment, a transfer support apparatus having two base portions in the Y-axis direction has been described. However, the number of base portions may be one or three or more. Further, in addition to the above-described embodiment, when actually using the transfer support device 10, a protective cover or the like considering the safety of the caregiver and the cared person, etc. However, in the present embodiment, the description is omitted in order to clearly explain the technology.

<Embodiment 2 of the Invention>

  In the second embodiment, as the first to third moving bodies or the fourth to sixth moving bodies appropriately move in the same direction along the first or second support columns, the first to third moving bodies The first or second base portion is configured to approach the support column side, and the placement surface of the first or second base unit is configured to approach the first or second support column in parallel.

As shown in FIG. 7, in order for the base portion 13 and the link 14 to approach the frame portion 16, at least the length from the tip of the base portion 13 to the contact point between the link 14 and the moving body 12 is the moving body. It is necessary to make it smaller than the height of the upper end position of the 12 movable ranges.
Note that this is not the case when each link 14 supports the base portion 13 from below.

  As shown in FIG. 7, when the base unit 13 is close to the frame unit, the base unit can be used as a support column when the transfer support device is not used, such as when it is moved or stored in a hospital, home, or care facility. Space can be saved because it can be stored close together.

  Furthermore, the present invention is not limited to the first and second embodiments described above, and various modifications can be made without departing from the gist of the present invention already described.
