Description

  The present invention relates to a care transfer device for easily transferring a care receiver between a bed and a wheelchair.

  Conventionally, care recipients who are difficult to move from bed to wheelchair by themselves have been carried by caregivers, but for the purpose of reducing the labor of such transfer care, various transfer devices for care Has been proposed. For example, in JP 2011-172898 A (Patent Document 1), a body part on which a cared person is placed, and a main body part including a carriage part that is movable on the floor and supports the board part, A nursing care transfer device is disclosed.

  By the way, in the nursing care transfer device described in Patent Document 1, the mounting portion is attached to the lifting body of the main body portion so as to be rotatable about the rotation axis, and the care recipient gets on the mounting portion. By raising and lowering the lifting / lowering body in the state, the riding section is rotated by the weight of the cared person, so that the cared person shifts from the supine position to the sitting position.

  However, in the structure of Patent Document 1, since the mounting portion is configured to passively rotate using the weight of the cared person, depending on the posture or body shape of the cared person, the intended sitting position There was also a risk that the transition to would not be realized smoothly.

  It is also conceivable to stably realize the transition to the care receiver's sitting position by applying a rotational force to the rotating shaft with an electric motor or the like to actively rotate the mounting portion. However, since an actuator for rotating the mounting portion is required in addition to the actuator for raising and lowering the mounting portion, there are problems such as an increase in the size of the device and a complicated structure. In addition, since a large output is required for the lifting / lowering actuator of the riding section, there is a possibility that the use of a high-power actuator increases the size and cost of the device.

  The present invention has been made in the background of the above-mentioned circumstances, and the problem to be solved is a care of a novel structure in which the posture of the care recipient can be actively changed by a simple and compact structure. An object of the present invention is to provide a transfer device.

  Hereinafter, the aspect of this invention made | formed in order to solve such a subject is described. In addition, the component employ | adopted in each aspect as described below is employable by arbitrary combinations as much as possible.

  That is, the first aspect of the present invention is a nursing care transfer device including a riding part on which a cared person is placed and a main body part having a carriage part that is movable on the floor and supports the riding part. And the said main-body part is provided with the 1st movable arm and the 2nd movable arm supported by the said trolley | bogie part, and these 1st movable arm and the 2nd movable arm can be tilted relatively. The mounting portion is constituted by a first support plate and a second support plate that are connected and tilted integrally with the first movable arm and the second movable arm, and are arranged in the length direction. Both ends of the first actuator that outputs by expansion and contraction of the first actuator are attached to each of the first movable arm and the carriage unit so as to be tiltable, and the second actuator that outputs by expansion and contraction in the length direction. Both ends are the second movable arm And a predetermined part of the first movable arm and the second movable arm connected to each other can be positioned with respect to the carriage part by positioning means. It is said that it is said.

  According to such a transfer device for nursing care according to the first aspect, the lifting and lowering operation of the entire riding section, and the first support plate and the second support constituting each of the back plate and the seat plate The relative tilting movement of the plate is realized by the first actuator and the second actuator. Therefore, the raising / lowering operation that requires a large force and the tilting operation that can be realized with a small force are both effectively realized by the small and low-power first and second actuators.

  That is, by extending the first actuator and the second actuator at the same time, the entire mounting portion can be raised, and by simultaneously contracting the first actuator and the second actuator, the mounting portion The whole can be lowered. As a result, the output of the first actuator and the output of the second actuator can be used in combination when the riding part that requires a large force to lift the cared person is raised. However, it is possible to obtain a large force required for the lifting operation even if the output is small and the output is set small.

  On the other hand, the first support plate and the second support plate can be tilted relatively by extending or contracting one of the first actuator and the second actuator relative to the other. it can. Thereby, the support plate on the back plate side is tilted with respect to the support plate on the seat plate side, and a back up or the like for raising the upper body of the care receiver is realized. Since such a tilting motion can be realized with a smaller force than the lifting operation, it can be sufficiently handled by only one of the small and low-power first actuator and the second actuator.

  In addition, both end portions of the first actuator and the second actuator are pin-connected to each one of the movable arm and the carriage unit, and predetermined portions of the first movable arm and the second movable arm are connected to the carriage unit.

It is being fixed to either one of the parts, and the positioning means is constituted by the third actuator.

  According to the second aspect, the third actuator having one end fixed so as not to tilt with respect to either the movable arm or the carriage is provided. As a result, the predetermined portions of the first movable arm and the second movable arm can be positioned in the axial direction (length direction) and the direction perpendicular to the axis of the third actuator, and the mounting portion is brought to the predetermined position. It is held stably.

  Furthermore, in this aspect, the first to third actuators are simultaneously extended or contracted to realize the lifting / lowering operation of the mounting portion. Therefore, during the lifting / lowering operation of the mounting portion, the first actuator and the second actuator In addition to the output of the third actuator, the output of the third actuator can also be used. Therefore, even if each actuator is smaller and has a lower output, it is possible to effectively realize the lifting operation requiring a large force.

  According to a third aspect of the present invention, in the transfer device for nursing care described in the first aspect, a support column is fixed to the carriage unit at a lower end, and the first movable arm and the first unit are fixed to the support column. A predetermined portion of the second movable arm is slidably attached in the length direction of the column and positioned in a direction perpendicular to the axis of the column, and at least one of the first movable arm and the second movable arm And a lock means for restricting relative tilt between the support column and the support column, and the first movable arm and the second movable arm can be positioned in the length direction of the support column. Including the positioning means.

  According to the third aspect, the first and second movable arms are positioned in the direction perpendicular to the axis of the support by the support whose bottom end is fixed so as not to tilt with respect to the carriage, and the first and second When at least one of the movable arms is restricted from tilting with respect to the support column by the lock means, the mounting portion can be stably held at a predetermined vertical position.

  Furthermore, in this aspect, since the positioning means is configured by using the support column and the locking means, the mounting portion can be positioned and held by a simple structure with few actuators.

  According to a fourth aspect of the present invention, in the transfer device for care described in any one of the first to third aspects, a connecting portion between the first movable arm and the second movable arm is provided by positioning means. Positioning is possible with respect to the carriage unit.

  According to the fourth aspect, when the support plate serving as the back plate is tilted and moved with respect to the support plate serving as the seat plate, no matter which of the first and second support plates constitutes the seat plate, It can prevent that the support plate used as a seat plate moves to a surface direction with the change of the inclination angle of the support plate used as a plate.

  According to the present invention, the first actuator for tilting each of the first support plate and the second support plate cooperates with the second actuator, so that the lifting operation of the mounting portion requiring a large force can be performed. Since it is realized, it is possible to adopt a low output as each actuator, and it is possible to reduce the size and cost of the actuator. Further, by providing positioning means that can position a predetermined portion of the movable arm with respect to the carriage unit, it is possible to stably hold the riding portion at a predetermined position.

  Embodiments of the present invention will be described below with reference to the drawings.

  1 to 4 show a nursing care transfer device 10 as a first embodiment of the present invention. The care transfer device 10 includes a mounting portion 12 on which a cared person rides and a main body portion 14 that supports the mounting portion 12. In the following description, the vertical direction means the vertical direction in FIG. 3 which is the vertical vertical direction in principle.

  More specifically, the mounting portion 12 includes a first support plate 16 and a second support plate 18. The first support plate 16 and the second support plate 18 are substantially flat members formed of hard synthetic resin or the like, and have substantially the same shape. The first and second support plates 16 and 18 can also improve the tactile sensation when the cared person comes into contact by pasting a cushion material or the like on the surface.

  The first and second support plates 16 and 18 are attached to the main body 14. The main body 14 includes a carriage 20 that can move on the floor surface. The carriage unit 20 has a structure in which a plurality of wheels 24 are provided on a substantially C-shaped plate-like leg portion 22 that extends substantially parallel to the floor surface, and is freely movable on the floor surface by the wheels 24. Yes. The cart unit 20 of the present embodiment is adapted to be moved by human power, but may be capable of self-propelled by, for example, an electric motor. Preferably, stopper means for restricting movement of the carriage unit 20 by the wheels 24 may be provided.

  Further, an arm portion 26 is disposed above the carriage unit 20. The arm portion 26 includes a first movable arm 28 and a second movable arm 30 each of which is a high-rigidity member extending linearly. Each end of the arm portion 26 is flexibly connected by a rotating shaft 32 to allow relative tilting. The structure is made.

  Further, the first movable arm 28 is connected to the carriage unit 20 by the first actuator 34, and the second movable arm 30 is connected to the carriage unit 20 by the second actuator 36. Each of the first actuator 34 and the second actuator 36 is a direct acting actuator that outputs by expansion and contraction in the length direction. In this embodiment, a gear train, a crank, and the like are appropriately combined with the electric motor. It is considered as an electric actuator. The lower end of the first actuator 34 is pin-coupled to the leg portion 22 of the carriage unit 20 so as to be tiltable, and the upper end is pin-coupled to the middle portion in the longitudinal direction of the first movable arm 28 so as to be tiltable. Yes. Similarly, the lower end of the second actuator 36 is pin-coupled to the leg portion 22 of the carriage 20 so as to be tiltable, and the upper end is pin-coupled to the middle portion of the second movable arm 30 in the longitudinal direction. ing. The upper and lower ends of the first and second actuators 34 and 36 are both tiltable about a central axis parallel to the rotation axis 32 with respect to the carriage unit 20 and the movable arms 28 and 30. It is desirable to prevent tilting in other directions. Further, in the present embodiment, the connecting portions of the first and second movable arms 28 and 30 where the first and second actuators 34 and 36 are connected are covered by the cover 38, so that contact of fingers and the like to the connecting portions is avoided. Has been.

  Furthermore, the connection portion of the first and second movable arms 28 and 30 by the rotating shaft 32 is coupled to the carriage unit 20 by a third actuator 40. The third actuator 40 is a direct acting electric actuator similar to the first and second actuators 34 and 36, and is disposed between the first and second actuators 34 and 36. The lower end of the third actuator 40 is fixed to the leg portion 22 of the carriage unit 20 so as not to tilt, and the upper end is extrapolated to the rotary shaft 32 so as to be attached to the first and second movable arms 28 and 30. On the other hand, it is connected so as to be tiltable about the rotation shaft 32. In the present embodiment, the upper end of the third actuator 40 is axially coupled to the movable arms 28 and 30 by the rotation shaft 32, so that tilting around the rotation shaft 32 is prevented.

  Thus, the arm part 26 of this embodiment is connected and supported by the cart part 20 by the 1st-3rd actuators 34,36,40. Here, since the connection part of the 1st, 2nd movable arms 28 and 30 is supported by the 3rd actuator 40 fixed to the trolley | bogie part 20, the 1st and 2nd movable arms 28 and 30 are used. Are connected in the axial direction (length direction) and the direction perpendicular to the axis of the third actuator 40.

  That is, when the mounting portion 12 is supported only by the first and second actuators 34 and 36, as shown by a two-dot chain line in FIG. 5A, the connecting portions of the first and second movable arms 28 and 30 are connected. Therefore, the tilt angles of the first and second movable arms 28 and 30 are not uniquely set and maintained with respect to the lengths of the first and second actuators 34 and 36.

  Therefore, in the care transfer device 10 of the present embodiment, as shown in FIG. 5B, the connection portions of the first and second movable arms 28 and 30 are supported by the third actuator 40. The vertical position of the connecting portion of the first and second movable arms 28 and 30 is defined by the length of the third actuator 40. Accordingly, the height and the inclination angle of the first movable arm 28 are set and held by the length of the third actuator 40 and the length of the first actuator 34, and the length of the third actuator 40 and the second actuator 34 are set. Depending on the length of the actuator 36, the height and the inclination angle of the second movable arm 30 are set and held. As is clear from the above description, in this embodiment, the positioning means for positioning the predetermined portion of the arm portion 26 is constituted by the third actuator 40, and the first movable arm 28 and the second movable arm 28 are arranged. The connecting portion of the arm 30 can be positioned with respect to the carriage unit 20. Note that the first to third actuators 34, 36, and 40 are held at a predetermined length by a detent torque of the electric motor in a non-energized state.

  The mounting portion 12 is attached to the arm portion 26 supported by the first to third actuators 34, 36, and 40. That is, the first support plate 16 constituting the mounting portion 12 is fixed to the first movable arm 28 and is tilted integrally with the first movable arm 28, and is mounted. The second support plate 18 constituting the part 12 is fixed to the second movable arm 30 and tilted integrally with the second movable arm 30. The first and second support plates 16 and 18 may be detachably attached to the first and second movable arms 28 and 30. In that case, it is desirable to provide a positioning member for relatively positioning the first and second support plates 16 and 18.

  In the nursing care transfer device 10 having such a structure, as shown in FIGS. 6A to 6C, the lifting and lowering of the mounting portion 12, the first support plate 16 and the second of the mounting portion 12. The relative tilting with respect to the support plate 18 is realized by the first and second actuators 34 and 36 and the third actuator 40.

  That is, by extending and contracting the first to third actuators 34, 36, 40 by the same length at the same time, the first and second movable arms 28, 30 as shown by the two-dot chain line in FIG. Rises or falls while maintaining a relative inclination angle. Accordingly, the mounting portion 12 can be raised or lowered while maintaining the relative inclination angle of the first and second support plates 16 and 18 fixed to the first and second movable arms 28 and 30. it can.

  On the other hand, as shown in FIG. 6B, by extending and contracting the first actuator 34 while holding the third actuator 40 at a predetermined length, as shown by a two-dot chain line in FIG. 6B. In addition, the inclination angle of the first movable arm 28 with respect to the second movable arm 30 can be changed. Therefore, the first support plate 16 fixed to the first movable arm 28 can be inclined with respect to the second support plate 18 fixed to the second movable arm 30. Similarly, as shown in FIG. 6C, the first movable arm 30 of the second movable arm 30 is expanded and contracted by holding the third actuator 40 at a predetermined length and expanding and contracting the second actuator 36. The second support plate 18 can be tilted with respect to the first support plate 16 by changing the tilt angle with respect to 28. Thus, the care receiver can be shifted from the supine position to the sitting position on the mounting portion 12 by raising the back, or the front end of the seat surface can be slightly lifted in the sitting position to prevent the care receiver from falling forward. It becomes feasible.

  However, for example, by changing the lengths of the second and third actuators 36 and 40 while maintaining the length of the first actuator 34, the first movable arm 28 and the first support plate 16 can be changed. It is also possible to change the inclination angle. Similarly, the inclination of the second movable arm 30 and the second support plate 18 is achieved by changing the lengths of the first and third actuators 34 and 40 while maintaining the length of the second actuator 36. The angle can also be changed.

  According to the nursing care transfer device 10 having the structure according to the present embodiment, the first actuator 34 attached to the first movable arm 28 when the riding portion 12 that requires a large force is lifted and lowered. The second actuator 36 attached to the second movable arm 30 cooperates with the output. Therefore, even if the first and second actuators 34 and 36 are small and have a low output, a large force necessary for raising and lowering the mounting portion 12 can be obtained.

  Moreover, in the present embodiment, the positioning means is constituted by the third actuator 40, and when the riding section 12 is raised and lowered, in addition to the outputs of the first and second actuators 34 and 36, the third actuator 40 Is also used. Therefore, the first to third actuators 34, 36, and 40 can be used with lower output, and the actuator can be more advantageously reduced in size, cost, and energy saving.

  On the other hand, the tilting movement of the first and second support plates 16 and 18 constituting each one of the back plate and the seat plate requires only a small force as compared with the raising and lowering of the mounting portion 12. Only one of the first and second actuators 34 and 36 having a low output can sufficiently obtain the necessary force. Therefore, operations such as raising the back can be effectively realized by the small and energy-saving first and second actuators 34 and 36.

  As described above, in the nursing care transfer device 10, the actuator used for the raising / lowering operation of the mounting unit 12 and the actuator used for the tilting (back-raising) operation of the mounting unit 12 are made common to each actuator. Thus, the maximum output required when raising and lowering the mounting portion 12 can be set large while suppressing the output required for reducing the size, reducing the cost, and saving energy.

  The third actuator 40 is disposed between the first actuator 34 and the second actuator 36, and the upper end is attached to the connection portion between the first movable arm 28 and the second movable arm 30. Therefore, when the first and second support plates 16 and 18 are tilted, the movement of the first and second support plates 16 and 18 in the front-rear direction is reduced or avoided. Therefore, it is possible to realize the back up without giving the cared person riding on the riding section 12 anxiety due to the movement in the front-rear direction, and to give a sense of security with a stable riding comfort. it can.

  7 to 10 show a nursing care transfer device 50 as a second embodiment of the present invention. The care transfer device 50 includes a mounting portion 12 on which a cared person rides and a main body portion 52 that supports the mounting portion 12.

It can be restricted. That is, as shown in FIG. 13, columnar support shafts 62 and 62 projecting at the connection side end portions are formed on the side surfaces of the first and second support plates 16 and 18, and these support shafts are supported. Locking protrusions 64 are formed on the outer sides of the shaft portion 62 in the front and rear (substantially left and right in FIG. 11). The locking protrusion 64 has a substantially cylindrical shape similar to that of the support shaft part 62 as a whole, and a protrusion 66 that protrudes toward the outer peripheral side is integrally formed at the upper part of the front and rear sides. It has a large diameter partially. In the present embodiment, the support shaft portion 62 and the locking projection 64 constituting the locking means 60 are both provided on the side surfaces of the first and second support plates 16 and 18 on the arm portion 26 side. The locking means 60 is disposed on the support 56 side.

  Further, a connecting member 68 is attached to the support shaft portion 62 of the first support plate 16 and the support shaft portion 62 of the second support plate 18. As shown in FIGS. 12 and 13, the connecting member 68 is a substantially oblong member, and two circular recesses corresponding to the support shaft portions 62 and 62 are formed on one surface in the thickness direction. Yes. Then, the support shaft portions 62 and 62 of the first and second support plates 16 and 18 are rotatably inserted into the two circular recesses, whereby the first support plate 16 and the second support plate 18. Are connected to each other by a connecting member 68 in a state in which relative tilting is allowed.

  Furthermore, a slider 70 is attached to the connecting member 68. The slider 70 has a substantially rectangular box shape opened to one side, and a fitting hole 72 penetrating in a substantially oval cross section is formed on the bottom surface. A pair of first insertion holes 74 and 74 and a pair of second insertion holes 76 and 76 are formed in the upper wall portion of the slider 70. The first insertion holes 74 are formed at both end portions in the front-rear direction, and open in a size and shape that allow the locking projections 64 to pass therethrough. On the other hand, the second insertion hole 76 is formed on the inner side in the front-rear direction with respect to the first insertion hole 74, and is opened in a size and shape that allows the locking protrusion 64 to pass in the same manner as the first insertion hole 74. doing. A first locking portion 78 is formed between the first insertion hole 74 and the second insertion hole 76 in the upper wall portion of the slider 70, and the second insertion holes 76 and 76 are formed. Between, the 2nd latching | locking part 80 is formed.

  Then, when the connecting member 68 that is externally inserted into the support shaft portions 62 and 62 of the first and second support plates 16 and 18 is inserted into the fitting hole 72 of the slider 70, the slider 70 is connected to the connecting member 68. The first and second support plates 16 and 18 are attached. Note that the fitting hole 72 has a shape that is longer in the front-rear direction than the connection member 68, and the slider 70 is slidable in the front-rear direction with respect to the connection member 68 when attached to the connection member 68. .

  With the lock means 60 having such a structure, the inclination angle of at least one of the first and second support plates 16 and 18 with respect to the support column 56 can be maintained.

  That is, as shown in FIG. 13A, in a state where the connecting member 68 is positioned at the center portion of the fitting hole 72 of the slider 70, the connecting member 68 is connected to the lower wall portion of the slider 70 and the second locking portion 80. And the locking projections 64 of the first and second support plates 16 and 18 are brought into contact with the first locking portion 78 on one side, so that the slider 70 moves upward.

As a result, in both the first and second support plates 16 and 18, the locking projection 64 and the support shaft 62 are relatively positioned in the slider 70, so that the first and second supports Both the plates 16 and 18 are held so as to spread in the direction perpendicular to the axis of the column 56 while being restricted from tilting with respect to the column 56.

  Next, as shown in FIG. 13B, by moving the slider 70 to the right in FIG. 13 by a predetermined amount, the locking protrusion 64 of the first support plate 16 is moved to the first first plate. It moves to the opening position of the insertion hole 74 and can be pulled out from the slider 70 through the first insertion hole 74. Thereby, the tilting of the first support plate 16 with respect to the support column 56 is allowed around the support shaft portion 62. Furthermore, the locking protrusion 64 of the second support plate 18 has the protruding portion 66 locked by the first locking portion 78, so that the upward protrusion from the slider 70 is restricted. The plate 18 is held so as to spread in the direction perpendicular to the axis of the column 56 with the tilting around the support shaft portion 62 being restricted.

  Similarly, when the slider 70 is moved to the left in FIG. 13 by a predetermined amount, the locking projection 64 of the second support plate 18 can be pulled out from the slider 70 through the other first insertion hole 74. Thus, the tilting of the second support plate 18 with respect to the column 56 is allowed around the support shaft portion 62. Furthermore, the locking protrusion 64 of the first support plate 16 has a protruding portion 66 locked to the first locking portion 78 and is restricted from being pulled out upward from the slider 70. The plate 16 is held so as to be spread in the direction perpendicular to the axis of the support column 56 by restricting the tilting around the support shaft portion 62.

  In addition, as shown in FIG. 13C, when the slider 70 is further moved to the right, the locking protrusion 64 of the first support plate 16 moves upward from the slider 70 through the first insertion hole 74. And the locking projection 64 of the second support plate 18 is allowed to be pulled upward from the slider 70 through the second insertion hole 76, so that the first and second supports Both the plates 16 and 18 can be tilted relative to the column 56. Thereby, for example, when storing the nursing care transfer device 50, the first and second support plates 16 and 18 are tilted until they stand substantially vertically, and the mounting portion 12 is folded and stored compactly. Can do. The connecting member 68 has a larger dimension in the front-rear direction than the first and second insertion holes 74 and 76, and is always pulled out from the slider 70 through the first and second insertion holes 74 and 76. It is prevented.

  As described above, at least one of the first and second support plates 16 and 18 is restricted by the locking means 60 so that the relative angle change with respect to the column 56 is limited, and thus the first and second support plates 16 and 18 are extrapolated to the column 56. The connecting portion of the second movable arms 28 and 30 is set and held at a predetermined vertical position according to the lengths of the first and second actuators 34 and 36. Thereby, a positioning means for positioning a predetermined portion of the arm portion 54, that is, a connecting portion of the first and second movable arms 28 and 30, includes the support column 56 and the locking means 60.

  The nursing care transfer device 50 having such a structure is similar to the nursing care transfer device 10 of the first embodiment, and ascends and descends the mounting portion 12 and tilts the first and second support plates 16 and 18. Is realized by the outputs of the first and second actuators 34 and 36.

  That is, as shown in FIG. 13A, the first and second actuators 34 are held while the first and second support plates 16 and 18 are held by the locking means 60 so as to spread in the direction perpendicular to the axis of the column 56. , 36 are extended by the same length, so that the mounting portion 12 can be raised along the column 56 as shown by a two-dot chain line in FIG. Similarly, the mounting portion 12 can be lowered along the column 56 by contracting the first and second actuators 34 and 36 by the same length.

  Furthermore, by operating the locking means 60 to release the lock of the first support plate 16 and permit tilting as shown in FIG. 13 (b), only the first actuator 34 is expanded and contracted. As shown in FIG. 14B, the first support plate 16 can be tilted. Since the second support plate 18 is held so as not to be tiltable with respect to the support column 56 by the lock means 60, the second support plate 18 is kept substantially horizontal. Similarly, the first support plate 16 can be held horizontally by the lock means 60, and the second support plate 18 can be tilted by the expansion and contraction of the second actuator 36 (see FIG. 14C).

  Further, in the state where only the tilt of the first support plate 16 is allowed by the locking means 60 shown in FIG. 13B, the first actuator 34 and the second actuator 36 are expanded and contracted by substantially the same length. It is also possible to displace the mounting portion 12 up and down while maintaining the relative inclination angle of the first support plate 16 and the second support plate 18.

  According to the nursing care transfer device 50 having the structure according to the present embodiment as described above, similarly to the first embodiment, the first and second small actuators 34 and 36 have a small and low output, and the mounting portion 12. Since a large force required for the lifting / lowering operation can be obtained, energy saving and cost reduction can be achieved.

  Further, in the present embodiment, the support 56 and the lock means 60 are provided as positioning means, and the third actuator 40 is unnecessary. Therefore, it is possible to operate with less energy consumption and to have a simpler and more compact structure.

  As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited by the specific description. For example, in the above-described embodiment, the first movable arm 28 and the first support plate 16 are formed separately and fixed afterward. However, the first support plate 16 is integrally formed with the first movable arm 28. May be. Similarly, the second movable arm 30 and the second support plate 18 can be integrally formed.

  In the embodiment, the first support plate 16 and the second support plate 18 have substantially the same shape, but the first and second support plates 16 and 18 may have different shapes. Specifically, a shape suitable for the seat plate can be adopted as the first support plate 16 and a shape suitable for the back plate can be adopted as the second support plate 18.

  Further, the connecting portion between the first movable arm 28 and the second movable arm 30 is not limited to the structure positioned by the positioning means. For example, the third actuator 40 and the support column 56 are connected to the first and second columns. It may be provided outside the actuators 34 and 36 and attached to either one of the first and second movable arms 28 and 30. Specifically, as shown in FIG. 15, the third actuator 40 may be attached to the first movable arm 28. In this case, the first movable arm 28 can be tilted by expanding and contracting the first to third actuators 34, 36, and 40, respectively. Further, as shown by a two-dot chain line in FIG. 15, when the first movable arm 28 is tilted, the second movable arm 30 is displaced in the horizontal direction.

  In the first embodiment, the third actuator 40 has a lower end fixed to the carriage unit 20 and an upper end attached to the arm unit 26 so as to be tiltable around the rotation shaft 32. For example, the upper end may be fixed to the arm part 26 and the lower end may be attached to the carriage part 20 so as to be tiltable about an axis parallel to the rotation shaft 32.

  In addition to the first actuator 34, an auxiliary actuator may be attached to the first movable arm 28 so that a larger output can be exhibited. Similarly, an auxiliary actuator can be attached to the second movable arm 30.

  The locking means 60 shown in the second embodiment is merely an example, and the specific structure is not particularly limited.

  The care recipient comprehensively refers to a person who is difficult to transfer between the bed and a wheelchair by himself and needs the assistance of the other person, and includes a victim and the like. Therefore, the transfer device for care according to the present invention can be suitably used not only for care in a narrow sense but also for care in a broad sense including care in a medical field.
