1 and 2 is changed from the posture shown in FIG. 1 to the posture shown in FIG. 2 when lifting the person being assisted. The transfer support apparatus 100 moves in a space with the person being assisted lifted, thereby transporting the person being assisted from one place to another. After reaching the other place, the transfer support device 100 is transformed from the posture shown in FIG. 2 to the posture shown in FIG. 1, thereby ending the work of transporting the person being assisted to another place. In addition, although it is good to carry a person being assisted with the assistance of the assistant, the present invention is not limited to this.

As shown in FIG. 1, the transfer support device (moving body, transport vehicle) 100 includes a carriage unit (main body unit) 10, an arm unit (movable unit) 20, and a holding unit 30. The transfer support apparatus 100 has a carriage structure and can move on a plane. The transfer assistance apparatus 100 moves according to the driving force generated by the electric motor built in its own casing. However, the transfer support apparatus 100 may be configured to move according to the pushing / pulling force of the assistant. That is, it is arbitrary whether or not the transfer support apparatus 100 is mounted with a drive source such as an electric motor. In addition, the specific aspect that the transfer assistance apparatus 100 moves in space is arbitrary, and it may be moved in space by belt feeding instead of rotation of the wheels.

The carriage unit 10 includes a base plate 11, a wheel unit 12, a wheel unit 13, a wheel unit 14, a wheel unit 15, a support column unit 16, a rail unit 17, a slide control unit 18, a storage unit 19, and a seating unit 90. The arm unit 20 includes a slide unit 21, a handle unit (gripping unit) 22, and a link mechanism 23. The holding unit 30 includes a front holding unit (main holding unit) 40 and a pair of side surface holding units (sub holding units) 50 and 60. The front holding unit (first holding unit) 40, the side holding unit (second holding unit) 50, and the side holding unit (third holding unit) 60 are provided to hold the body of the person being assisted from different directions. It has been. Note that the number of directions in which the body of the person being assisted by the holding unit 30 is held is arbitrary, and should not be limited to three directions as in this example.

The base plate 11 is a plate-like member extending with the x-axis direction as a longitudinal direction. The base plate 11 is composed of, for example, a metal plate (iron plate or the like). The base plate 11 has four corners, and wheel portions 12 to 15 are provided at the respective corners of the base plate 11.

Wheel parts

12 and 13 function as main wheel parts. The

wheel portions

14 and 15 function as auxiliary wheel portions. The wheel which the wheel part 12 has, and the wheel which the wheel part 13 has rotate according to the driving force transmitted from a motor. On the other hand, the driving force generated by the motor is not transmitted to the wheels of the wheel unit 14 and the wheels of the wheel unit 15. Each wheel provided with respect to the

wheel parts

14 and 15 functions as a passive wheel.

The wheel unit 12 includes a wheel 12a, an axle holding unit 12b, and a wheel cover unit 12c. The rotating shaft of the wheel 12a is pivotally supported by the axle holding portion 12b. The axle holding part 12b is fixed to the wheel cover part 12c. The wheel cover portion 12 c is disposed at a position covering the upper side of the wheel 12 a and is fixed to the base plate 11.

Like the wheel part 12, the wheel part 13 includes a wheel 13a, an axle holding part 13b, and a wheel cover part 13c. The configuration of the wheel portion 13 is substantially the same as that of the wheel portion 12, and a duplicate description is omitted.

The

wheels

12a and 13a are arranged coaxially and are arranged so as to sandwich the base plate 11. The rotation axis of the wheel 12a is not shared with the rotation axis of the wheel 13a. The wheel 12a and the wheel 13a are individually controlled for rotation, and thereby the turning support device 100 can be turned. The axle holding part 12b holding the wheel 12a may be turnable with respect to the wheel cover part 12c. In this case, the rotation direction of the wheel 12a can be arbitrarily controlled in the xz plane.

Similarly to the wheel part 12, the wheel part 14 includes a wheel 14a, an axle holding part 14b, and a wheel cover part 14c, and the wheel part 15 includes a wheel 15a, an axle holding part 15b, and a wheel cover part 15c. The structure of each

wheel part

14 and 15 is as substantially the same as the wheel part 12, and the overlapping description is abbreviate | omitted.

Wheel parts

14 and 15 are arranged on the same axis. The wheel 14a which the wheel part 14 has functions as a passive wheel. The same applies to the wheel 15a included in the wheel portion 15. Thereby, the movement of the transfer assistance apparatus 100 can be stabilized.

The column portion 16 is a columnar member that extends with the y-axis direction as a longitudinal direction, and is erected with respect to the base plate 11. The column portion 16 is disposed between the

wheel portions

12 and 13. The specific structure of the support | pillar part 16 is arbitrary. For example, the column part 16 is a hollow columnar member. An electric motor (drive source), a battery (power source), wiring, electronic components, a transmission mechanism, and the like are housed inside the support column 16. The electric motor generates a driving force according to the electric power supplied from the battery. The driving force generated by the electric motor is transmitted to the wheels of the wheel portion via the transmission mechanism.

The rail part 17 is a convex structure part, and is provided with respect to the lateral side surface of the support | pillar part 16. FIG. The rail portion 17 extends in an arc shape on the xy plane. A slide portion 21 of the arm portion 20 is attached to the rail portion 17. The posture of the arm unit 20 changes while being guided by the rail unit 17. In addition, the rail part 17 may be provided also on the side surface on the opposite side on both sides of the support | pillar part 16. FIG. The mechanism for guiding the posture control of the arm unit 20 is arbitrary, and can be realized by a method other than the combination of the rail and the slider.

The slide control unit 18 controls the slide state of the slide unit 21 that slides on the rail unit 17. For example, the slide control unit 18 is frictionally engaged with the slide unit 21 so that the slide unit 21 does not move rapidly on the rail unit 17. Further, the slide control unit 18 is frictionally engaged with the slide unit 21 in order to fix the slide unit 21 on the rail unit 17. In addition, the specific method of the movement control of the slide part 21 by the slide control part 18 is arbitrary.

The accommodating part 19 is a box-shaped member and is provided with respect to the front side surface of the column part 16. In the accommodating part 19, for example, a motherboard on which electronic components (CPU (Central Processing Unit), memory, hard disk) are mounted is accommodated. For example, the CPU controls the driving of the electric motor described above in accordance with the execution of a program stored in the memory.

The seating portion 90 is provided on the base plate 11 so that the position can be adjusted from the base plate 11 to an upper position. When the transfer assist device 100 moves in space, the person being assisted by the holding unit 30 can take a sitting position, thereby effectively applying the physical burden on the person being assisted during movement. Can be reduced.

The arm unit 20 includes a slide unit 21, a handle unit 22, and a link mechanism 23. As apparent from FIGS. 1 and 2, the arm portion 20 is deformed so as to draw an arc on the xy plane. A holding part 30 is attached to the tip of the arm part 20. The base end of the arm portion 20 is supported by the support column portion 16.

The slide part 21 is engaged with the rail part 17, and is guided by the rail part 17 and slides so as to draw an arc on the xy plane. In order to facilitate the movement of the slide part 21, the slide part 21 and the rail part 17 may be engaged via a ball or the like.

The handle portion 22 is a portion that is held by an assistant and is connected to the slide portion 21. By providing the handle portion 22 with respect to the arm portion 20, it is possible to relieve the caregiver's anxiety that is received when the caretaker is lifted. The posture change of the arm portion 20 can be adjusted by an assistant holding the handle portion 22. Since the person being assisted is facing the person being assisted, it is easy to grasp the intention of the person being assisted, for example, the person being able to relax the speed of the posture change of the arm unit 20 according to the intention of the person being assisted. . As a result, the anxiety experienced by the person being assisted during lifting can be effectively alleviated.

The link mechanism 23 is engaged with the slide portion 21 and changes its posture according to the slide operation of the slide portion 21. The proximal end of the link mechanism 23 is engaged with the slide portion 21, and the distal end of the link mechanism 23 is engaged with the holding portion 30. By interposing the link mechanism 23 between the slide part 21 and the holding part 30, the holding part 30 can be displaced as intended. This makes it possible to displace the holding unit 30 in a natural manner. The specific configuration of the link mechanism 23 is arbitrary. The number of joints included in the link mechanism 23 is arbitrary, and is not limited to two as illustrated.

The holding unit 30 includes a front holding unit 40, a side holding unit 50, a side holding unit 60, a connecting unit 70, and a connecting unit 80.

The front holding part 40 is provided corresponding to the front (main surface) of the torso of the person being assisted. The front holding part 40 has a size that can hold a human torso part (for example, a part from the upper end of the rib cage to the upper anterior iliac fistula) as a whole. The front holding unit 40 holds the body of the person being assisted as a whole.

The side

surface holding portions

50 and 60 are provided corresponding to the side surfaces of the body of the person being assisted. The side

surface holding portions

50 and 60 are arranged in such a manner as to be able to hold a portion that swells downward in the human thorax. The side

surface holding portions

50 and 60 push and support the person being assisted on the front surface holding portion 40 from the diagonally rear side. The front holding unit 40, the

side holding units

50, 60, and the like can hold the person being assisted from three directions in a coordinated manner, whereby the person being assisted can be held more stably.

In addition, the side surface holding part 50 is attached to the front surface holding part 40 via the connecting part 70. The side surface holding part 60 is attached to the front surface holding part 40 via the connecting part 80. As will be apparent from the description below, the side

surface holding portions

50 and 60 are configured to be displaceable along an axis determined based on individual differences in the width and thickness of the body of the person being assisted. Accordingly, the person being assisted can be pushed and supported by the side

surface holding parts

50 and 60 in a manner suitable for each person being assisted on the front holding part 40.

The front holding part 40 has a base plate 41, a cushion material 42, and a storage part 43. The base plate 41 is covered with a cushion material 42. Thereby, the pain etc. which a caregiver receives when a caretaker leans against the front holding part 40 are reduced. The base end of each of the connecting

portions

70 and 80 is attached to the accommodating portion 43. The cushion material is configured by covering a cushioning inner member with a cover sheet (covering material, skin material). Similar to the front holding unit 40, the side holding unit 50 includes a base plate and a cushion material. The same applies to the side surface holding portion 60.

The operation of the transfer support device will be described with reference to FIGS. 3 corresponds to the transfer support device 100 in the posture shown in FIG. FIG. 4 corresponds to the transfer support device 100 in the posture shown in FIG.

First, the transfer support device 100 is disposed at a position where the person being assisted 150 can hold onto the holding unit 30. The person being assisted leans against the front holding part 40. The assistant adjusts the positions of the side

surface holding portions

50 and 60. The side

surface holding parts

50 and 60 are displaced along an axis defined based on individual differences in the width and thickness of the body part of the person being assisted. Accordingly, the person being assisted can be pushed and supported by the side

surface holding parts

50 and 60 in a manner suitable for each person being assisted on the front holding part 40. Thereafter, the side

surface holding portions

50 and 60 are positioned by an appropriate method.

Next, the transfer assistance device 100 lifts the person being assisted while the person being assisted 150 is held by the holding unit 30. The lifting operation of the person being assisted 150 by the transfer support apparatus 100 is executed by, for example, a driving force generated by a built-in motor. When lifting the person being assisted 150, the slide part 21 slides on the rail part 17 from the upper side to the lower side. The handle portion 22 is displaced according to the slide operation of the slide portion 21. Similarly, the link mechanism 23 is deformed according to the slide operation of the slide portion 21. With these cooperative operations, the posture of the holding unit 30 changes from the state shown in FIG. 3 to the state shown in FIG. As a result, the person being assisted by the holding unit 30 is lifted upward from the bed. In addition, it is clear from the above-mentioned description about the lowering operation of the person being assisted, and a duplicate description is omitted.

Next, a specific configuration of the holding unit 30 will be described with reference to FIGS. For the convenience of the following description, xyz coordinates are set as shown in FIG. The z axis coincides with the longitudinal direction of the holding surface (front surface, main surface) 44 of the front holding unit 40. The x-axis coincides with the direction away from the holding surface 44 of the front holding unit 40. The y-axis coincides with a direction parallel to the holding surface 44 of the front holding unit 40. Note that the x-axis, y-axis, and z-axis are orthogonal to each other. Note that the longitudinal direction of the front holding part 40 coincides with the extending direction of the thoracic vertebra of the person being assisted by the holding part 30.

As shown in FIG. 6, the side surface holding part 50 is configured to be movable along the axis LX1. The side surface holding part 60 is configured to be movable along the axis LX2. As apparent from FIG. 6, the axis LX1 has a predetermined inclination with respect to the zy plane. Similarly, the axis LX2 has a predetermined inclination with respect to the zy plane. The axis line LX1 and the axis line LX2 are in a line-symmetric relationship. In this case, the line LX0 located on the center of the front holding part 40 in the y-axis direction is a symmetric line.

The side

surface holding parts

50 and 60 have a width in the z-axis direction. Accordingly, it can be understood that the plane including the axis LX1 and the plane including the axis LX2 are configured to be plane-symmetric. In this case, the xz plane including the axis LX0 functions as a symmetry plane.

As schematically shown in FIG. 6, the side surface holding part 50 has a recessed shape according to the outer peripheral shape of the body part of the person being assisted against the front holding part 40. In other words, the inner surface (holding surface) 51 of the side surface holding portion 50 is provided with a recess 52. By providing the recessed part 52 with respect to the inner side surface 51 of the side surface holding | maintenance part 50, the contact area with respect to the side surface of the trunk | drum of a person to be assisted can fully be ensured. This makes it possible to more stably push and support the person being assisted 150. Similar to the side surface holding portion 50, a recessed portion 62 is provided on the inner side surface 61 of the side surface holding portion 60. In addition, the

hollow parts

52 and 62 are concave parts extending along the z-axis direction.

As shown in FIG. 7, a three-dimensional space is virtually set with the holding surface 44 of the front holding unit 40 as a reference surface (the reference surface matches the side surface shown in FIG. 7). A three-dimensional space is configured by the lattice points C1 to C4, the lattice points C11 to C14, and the lattice points C21 to C24. The lattice points C1 and C2 are located at the center of the front holding unit 40 in the y-axis direction. The plane including the lattice points C1 to C4, the plane including the lattice points C11 to C14, and the plane including the lattice points C21 to C24 are xz planes.

As shown in FIG. 7, the axis LX1 exists on the lattice points C1 and C14, and connects the lattice point C14 and the lattice point C1. The axis LX1 exists on the lattice points C2 and C13, and connects the lattice point C13 and the lattice point C2. The axis LX2 exists on the lattice point C24 and the lattice point C1, and connects the lattice point C24 and the lattice point C1. The axis LX2 exists on the lattice points C2 and C23, and connects the lattice point C23 and the lattice point C2. The plane including the lattice points C1, C2, C13, and C14 is plane symmetric with respect to the plane including the lattice points C1, C2, C23, and C24. At this time, the plane including the lattice points C1, C2, C3, and C4 functions as a symmetry plane. Although the axis line LX1 and the axis line LX2 are in a line-symmetrical relationship, both the axis lines LX1 and LX2 do not necessarily need to pass through the lattice point C1 shown in FIG. 7 (the same applies to the lattice point C2). That is, as shown in FIG. 7, when viewing the paper from the front, the axis LX1 may be translated to the left along the y axis, and the axis LX2 may be translated to the right along the y axis. Even in such a case, the effect of the present embodiment is not hindered.

The side surface holding unit 50 moves to the front surface holding unit 40 side along the axis LX1. In the process in which the side surface holding portion 50 moves close to the front surface holding portion 40, the distance in the x-axis direction between the side surface holding portion 50 and the front surface holding portion 40 is reduced. Accordingly, it is possible to suppress the person being assisted by the side

surface holding parts

50 and 60 in a mode suitable for each person being assisted on the front holding part 40.

The side surface holding part 60 moves to the front surface holding part 40 side along the axis LX2. The distance in the x-axis direction between the side surface holding portion 60 and the front surface holding portion 40 is reduced in synchronization with the movement of the side surface holding portion 60 along the axis LX2 toward the front surface holding portion 40. Accordingly, it is possible to suppress the person being assisted by the side

surface holding parts

Referring to FIG. 8, a method for setting the axis LX2 will be described. Since the setting method of the axis LX1 is clear from the description of the setting method of the axis LX2, the description of the setting method of the axis LX1 is omitted.

The angle θ formed by the axis LX2 with respect to the holding surface 44 of the front holding unit 40 is calculated by substituting the body shape values of the person being assisted 150A and the person being assisted 150B into a predetermined function. The body shape of the person being assisted 150A and the body shape of the person being assisted 150B are different from each other. Specifically, the trunk width of the person being assisted 150A is W1, and the trunk thickness is d1. The body width of the person being assisted 150B is W2, and the body thickness is d2. The conditions of W1 <W2 and d1 <d2 are satisfied. It is assumed that the centers of the

care recipients

150A and 150B in the y-axis direction are respectively on the center of the front holding part 40 in the y-axis direction (this is the same in the following embodiments).

The angle θ formed by the axis LX2 with respect to the holding surface 44 of the front holding unit 40 can be obtained from the following equation (1).

Thus, by obtaining the angle θ, the axis LX2, that is, the trajectory of the side surface holding portion is set. In addition, the specific calculation method of an axis line is arbitrary, and should not be limited to the above-described method.

Supplementary explanation for the above formula (1). As shown in FIG. 8, the axis LX2 exists on the side surface center point P1 of the trunk of the person being assisted 150A and the side surface center point P2 of the body of the person being assisted 150B. The side surface center point P1 is located at (x, y) = (d1 / 2, w1 / 2). The side surface center point P2 is located at (x, y) = (d2 / 2, w2 / 2). When the center in the y-axis direction of the body part of each person being assisted is set to the same position, the axis LX2 (angle θ) can be obtained by connecting the side surface center points of each person being assisted. Note that the center of the person being assisted in the y-axis direction is located on the above-described symmetry line LX0. The symmetry line LX0 coincides with a dividing line that divides the width W20 of the front holding portion 40 in the y-axis direction into two.

Body shape values such as W1, W2, d1, and d2 are obtained by actually measuring the body shape of the person being assisted. The width and thickness of the torso may be the width and thickness of the rib cage. For example, the angle θ = 41 ° is calculated under the conditions (the person being assisted 150A: the rib cage width W1 = 260 mm, the rib cage thickness 182 mm, the masked person 150B: the rib cage width W2 = 347 mm, and the rib cage thickness 258 mm).

The numerical range of the angle θ may have a certain width. The numerical range of the angle θ is also affected by which part of the person being assisted is supported by the side surface holding portion. As in this example, when the body part of the person being assisted is pushed and supported by the side surface holding part, the angle θ is preferably set in the range of 0 ° to 60 °. More preferably, the angle θ is set in the range of 30 ° to 60 °. This makes it possible to improve the holding characteristics of the person being assisted. The angle θ described above may be referred to as a movement angle of the side surface holding portion.

In this embodiment, the movement trajectory of the side surface holding unit is determined based on the body shape values measured from the caregivers of different body shapes, and the movement trajectory of the side surface holding unit corresponds to the body shape difference between the cared persons. become. By setting the movement trajectory of the side surface holding part in this way, even if there is a body type difference in the person being assisted on the front side holding part, the cared person is affected by the influence of the body type difference. It becomes possible to push and support the person being assisted by the side surface holding portion in a mode in which the discomfort received is suppressed. Moreover, according to this embodiment, the range of the care receiver who can respond with one holder can be expanded. This avoids the need to prepare a plurality of holder sizes.

In this embodiment, the propulsion direction of the side surface holding portion when the side surface holding portion is pressed against the person being assisted is approximately the direction in which the person being assisted is pressed by the side surface holding portion. Match. More specifically, when the caregiver presses the side holding part against the person being assisted, the direction in which the assistant pushes the side holding part coincides with the direction in which the person being assisted should be supported by the side holding part. To do. That is, the pushing direction of the side surface holding portion by the assistant and the pushing direction of the person being assisted by the side surface holding portion are substantially coaxial. Thereby, the position adjustment of the side surface holding portion can be performed in a natural manner, and it is possible to effectively suppress an excessive force from being applied to the person being assisted. Even when the set of side surface holding portions is returned from the closed state to the opened state, it is possible to suppress an excessive force from being applied to the person being assisted.

In the present embodiment, the axis LX2 coincides with the movement locus of the recess of the side surface holding portion. By moving the hollow part of the side surface holding part along the axis LX2, the hollow part of the side surface holding part is arranged in the vicinity of the center of the side surface of the body part of the person being assisted regardless of the body shape difference of the person being assisted. As a result, the inner side surface of the side surface holding part and the outer periphery of the body part of the person being assisted can be brought into contact with each other in a wider range, and the side surface holding part locally contacts the person being assisted. Can be effectively avoided.

With reference to FIG.9 and FIG.10, the attachment structure of each side

surface holding part

50 and 60 with respect to the front surface holding part 40 is demonstrated. As shown in FIG. 1 and FIG. 2, the side surface holding part 50 is attached to the front surface holding part 40 via a connecting part 70. Similarly, the side surface holding portion 60 is attached to the front surface holding portion 40 via the connecting portion 80.

As shown in FIG. 9, the connecting portion 70 includes an arm (moving side member) 71, a guide rail (fixed side member) 72, a slider (engaging portion) 73, and a slider (engaging portion) 74. The arm 71 is a rod-shaped member, and a side surface holding portion 50 is provided at the tip thereof. The arm 71 is attached to the guide rail 72 via

sliders

73 and 74. The arm 71 has a portion extending in parallel to the axis LX1. The guide rail 72 extends in parallel to the axis LX1. The

sliders

73 and 74 are fixed with respect to the arm 71.

The guide rail 72 is fixed to the front holding part 40. The slider 73 is engaged with the guide rail 72. Similarly, the slider 74 is engaged with the guide rail 72. The

sliders

73 and 74 can move on the guide rail 72 along the axis LX1. The attachment structure between the guide rail 72 and the slider 73 is arbitrary. A brake function is added to the

sliders

73 and 74. That is, the slider 73 is positioned on the guide rail 72 by, for example, frictional engagement with the guide rail 72. Thereby, the side surface holding part 50 can be positioned with respect to the front surface holding part 40. Note that the position fixing method of the arm 71 is arbitrary, and the arm 71 may be positioned by structural fitting.

Like the connecting portion 70, the connecting portion 80 includes an arm 81, a guide rail 82, a slider 83, and a slider 84. The structure of the connection part 80 is the same as that of the connection part 70, and the overlapping description is omitted.

As schematically shown in FIG. 10, when the front holding part 40 is viewed from the front, the

sliders

73 and 74 move on the guide rail 72 along the axis LX1. Similarly, the

sliders

83 and 84 move on the guide rail 82 along the axis LX2. When the front holding part 40 is viewed from the front, the axis LX1 and the axis LX2 are parallel to each other.

In the present embodiment, the arm 71 is configured to be movable along the axis LX1, and the side surface holding portion 50 attached to the tip of the arm 71 is configured to be movable along the axis LX1. At this time, the distance in the x-axis direction between the side surface holding part 50 and the front surface holding part 40 is narrowed in the process in which the side surface holding part 50 moves close to the front surface holding part 40. Thereby, the side surface holding part can be suitably pressed against the body part of the person being assisted even between the persons having physique differences.

As described with reference to FIG. 8, the body width and body thickness of the person being assisted may vary greatly depending on the body shape difference (physique difference) of the person being assisted. In this case, the side

surface holding portions

50 and 60 are suitably pressed against each person being assisted only by translating the side

surface holding portions

50 and 60 in a direction parallel to the holding surface 44 of the front surface holding portion 40. You may not get.

In the present embodiment, as described with reference to FIG. 8, the inclination θ of the axis with respect to the holding surface 44 of the front holding unit 40 based on the body shape values (body width, body thickness) of each person being assisted with different body shapes. The correlation of the body shape of each person being assisted is obtained. Specifically, the side surface holding portion can be moved along an axis that intersects the holding surface 44 of the front surface holding portion 40 with an inclination θ. This makes it possible to press the side surface holding portion in a similar manner against a predetermined portion of the body portion of each person being assisted even between the persons being assisted by different body shapes.

When providing a dent with respect to the holding surface of a side surface holding part, it is preferable to ensure a favorable contact state between the side surface of the body part of the person being assisted and the holding surface. In the present embodiment, as described above, the movement trajectory of the depression provided on the holding surface of the side surface holding unit is obtained based on the side surface center point of each person being assisted. As a result, the depression provided on the holding surface of the side holding part is arranged at a position corresponding to the center of the side of the person being assisted, and the side of the person being assisted is preferably held side by side regardless of the difference in body shape of the person being assisted. It becomes possible to push and support at the part. In addition, you may comprise the side surface holding |

maintenance parts

50 and 60 so that it can open and close cooperatively. You may comprise so that the side

surface holding parts

50 and 60 may be opened / closed separately.

Embodiment 2
The second embodiment will be described below with reference to FIGS. 11 and 12 are explanatory diagrams showing the moving direction of the side surface holding portion. FIG. 13 is an explanatory diagram illustrating a method for setting the moving direction of the side surface holding portion. 14 and 15 are explanatory views for explaining the attachment structure of the side surface holding portion.

In the present embodiment, unlike the first embodiment, as schematically shown in FIG. 11, when the front holding unit 40 is viewed from the front, the side holding unit 50 moves along the axis LX3 and the side holding unit 60. Moves along the axis LX4. As a result, it becomes possible to press the side surface holding portion against the portion where the rib cage of the person being assisted narrows, and the feeling of pressure applied to the person being assisted can be reduced. Note that the axis lines LX3 and LX4 are determined based on the difference in body shape of the person being assisted, as with the axis lines LX1 and LX2 in the first embodiment. This point will become clear from the following description. The second embodiment is based on the configuration of the transfer support apparatus 100 described in the first embodiment, and redundant description is omitted.

As shown in FIG. 11, when the side surface holding portion 50 moves inward (front holding portion 40 side) along the axis LX3, the side holding portion 50 is lower in the z-axis direction (longitudinal direction of the holding surface of the front holding portion 40). Move to the person's feet). The side surface holding part 60 moves downward in the z-axis direction when moving inward along the axis LX4. Note that the lower side in the z-axis direction matches the foot side of the person being assisted.

As schematically shown in FIG. 12, the axis LX3 extends parallel to the holding surface 44 of the front holding unit 40 and exists on the lattice points C3 and C14. The axis LX4 extends parallel to the holding surface 44 of the front holding unit 40 and exists on the lattice points C3 and C24. Although the axis line LX3 and the axis line LX4 are in a line-symmetrical relationship, both the axis lines LX3 and LX4 do not necessarily have to pass through the lattice point C3 shown in FIG. That is, as shown in FIG. 12, the paper surface is viewed from the front (the lattice point C1 is the upper side, the lattice point C2 is the lower side, the lattice point C21 is the right side, and the lattice point C11 is the left side), and the axis LX3 is along the y-axis. The axis LX4 may be translated to the right along the y axis. Even in such a case, the effect of the present embodiment is not hindered.

Referring to FIG. 13, a method for setting the axis LX4 will be described. Since the setting method of the axis LX3 is clear from the description of the setting method of the axis LX4, the description of the setting method of the axis LX3 is omitted.

When the width direction of the torso of the person being held held by the front holding part 40 is shown as a line L1 (see also FIG. 11), the angle θ formed by the axis LX4 with respect to the line L1 is the person 150A And each body shape value of the person being assisted 150B are calculated by substituting them into a predetermined function. The body shape of the person being assisted 150A and the body shape of the person being assisted 150B are different from each other. Specifically, the body width of the person being assisted 150A is W3, and the trunk length is h1. The trunk width of the person being assisted 150B is W4, and the trunk length is h2. The conditions of W3 <W4 and h1 <h2 are satisfied. The centers of the

care recipients

150A and 150B in the y-axis direction are assumed to be on the center of the front holding part 40 in the y-axis direction, respectively.

The angle θ formed by the axis LX4 with respect to the line L1 can be obtained from the following equation (2).

Thus, by obtaining the angle θ, the trajectory of the side surface holding portion as the axis LX4 is set. In addition, the specific calculation method of axis line LX4 is arbitrary, and should not be limited to the above-described method.

Supplementary explanation for the above formula (2). As shown in FIG. 13, the axis LX4 exists on a feature point P3 corresponding to the shoulder of the trunk of the person being assisted 150A and on a feature point P4 corresponding to the shoulder of the trunk of the person being assisted 150B. The point P3 is located at (z, y) = (− h1, W3 / 2). The point P4 is located at (z, y) = (− h2, W4 / 2). The axis LX4 can be determined by connecting the characteristic points determined from the trunk width and the trunk length of each caregiver when the center of the torso of each caregiver is in the same position in the y-axis direction. Note that the center of the person being assisted in the y-axis direction is located on the above-described symmetry line LX0.

Specific values of W3, W4, h1, and h2 are arbitrary. As the trunk width and trunk length, the width of the rib cage and the height of the rib cage may be adopted. For example, the angle θ = 79 ° is calculated under the conditions (the person being assisted 150A: the rib cage width W3 = 260 mm, the rib cage height 183 mm, the masked person 150B: the rib cage width W4 = 347 mm, the rib cage height 402 mm).

Note that, similarly to the above-described embodiment, the numerical range of the angle θ may have a certain width. In this example, the angle θ is preferably set in the range of 0 ° to 85 °. More preferably, the angle θ is set in the range of 35 ° to 85 °. More preferably, the angle θ is set in the range of 55 ° to 85 °. This makes it possible to improve the holding characteristics of the person being assisted. The angle θ described above may be referred to as a movement angle of the side surface holding portion.

As shown in FIG. 14, the side surface holding part 50 is attached to the front surface holding part 40 via a connecting part 70. The side surface holding part 60 is attached to the front surface holding part 40 via the connecting part 70. The connecting portion 70 includes an arm 71, a guide rail 72, a slider 73, and a slider 74. Similar to the connecting portion 70, the connecting portion 80 includes an arm 81, a guide rail 82, a slider 83, and a slider 84. The structure of the connection part 80 is the same as that of the connection part 70, and the overlapping description is omitted. These points are the same as those in the first embodiment, and redundant description is omitted.

As schematically shown in FIG. 15, the arm 71 has a portion extending along the axis LX3. The guide rail 72 extends along the axis LX3. The arm 71 is guided by the guide rail 72 and moves on the guide rail 72. Similarly, the arm 81 has a portion extending along the axis LX4. The guide rail 82 extends along the axis LX4. The arm 81 is guided by the guide rail 82 and moves on the guide rail 82.

In this embodiment, the movement trajectory of the side surface holding part is determined based on the body shape values (trunk width, trunk length) measured from the caregivers of different body shapes. It depends on the difference in body shape. This makes it possible to press the side surface holding portion in the same manner against the part where the individual's thorax is narrowed even among the persons being assisted with different body shapes. Moreover, according to this embodiment, the range of the care receiver who can respond with one holder can be expanded. This avoids the need to prepare a plurality of holder sizes.

In the present embodiment, as described with reference to FIG. 13, each person being assisted as the inclination θ of the axis with respect to the line L <b> 1 based on the body shape values (body width, trunk length) of each person having different body shapes. Find the correlation of the body shape. Then, the side surface holding portion can be moved along the axis intersecting the line L1 with the calculated inclination θ. This makes it possible to press the side surface holding portion in a similar manner against a predetermined portion of the body portion of each person being assisted even between the persons being assisted by different body shapes.

Embodiment

1, 2 is abbreviate | omitted. The third embodiment is based on the configuration of the transfer support apparatus 100 described in the first and second embodiments. The third embodiment is based on the axis setting method described in the first and second embodiments.

As schematically shown in FIG. 16, the axis LX5 exists on the lattice points C2 and C14. The axis LX6 exists on the lattice points C2 and C24. The side surface holding part 50 moves along the axis LX5. The side surface holding part 50 moves along the axis LX6. The axis LX5 coincides with the combined vector of the axis LX1 shown in FIG. 7 and the axis LX3 shown in FIG. The axis LX6 matches the combined vector of the axis LX2 shown in FIG. 7 and the axis LX4 shown in FIG. That is, the axis line LX5 is set by obtaining the axis lines LX1 and LX3 separately and obtaining a combined vector of the axis lines LX1 and LX3. The axis line LX6 is set by obtaining the axis lines LX2 and LX4 individually and obtaining a combined vector of the axis lines LX2 and LX4. Although the axis line LX5 and the axis line LX6 are in a line-symmetrical relationship, both the axis lines LX5 and LX6 do not necessarily have to pass through the lattice point C2 shown in FIG. That is, as shown in FIG. 16, the paper surface is viewed from the front (the grid point C1 is the upper side, the grid point C2 is the lower side, the grid point C21 is the right side, and the grid point C11 is the left side), and the axis LX5 is along the y-axis. The axis LX6 may be translated to the right along the y axis. Even in such a case, the effect of the present embodiment is not hindered.

It will be according to the body shape difference between the torso. As a result, the effects described in the first and second embodiments can be obtained synergistically. For example, even if there is a body shape difference in the person being assisted on the front surface holding portion, the side surface holding portion is in a state in which the discomfort experienced by the care recipient is suppressed due to the effect of the body shape difference. This makes it possible to push and support the person being assisted. In addition, it is possible to press the side surface holding portion in the same manner on the part where the thoracic stenosis of each person being assisted is reduced even among the persons being assisted by different body shapes. Moreover, the range of the care receiver who can respond with one holder can be expanded.
