  The seat portion 300 includes a pair of left and right rotational force receiving portions 326 provided so as to be able to transmit rotational force to each rotational shaft portion 342. In the illustrated example, the rotational force receiving portion 326 is a hexagon nut connected to the inner ring of the bearing or the rotary shaft portion 342. An operating tool 381 having a nut receiving portion capable of rotating the hexagon nut is used, and the rotary shaft portion 342 is rotated via the hexagon nut. Briefly, by rotating the operation tool 381 with respect to the rotation shaft portion 342 in a plane orthogonal to the front-rear direction, the rotation shaft portion 342 can be manually rotated and the sheet material 344 can be fed in the circumferential direction. For confirmation, the circumferential direction described with respect to the sheet material 344 is clockwise or counterclockwise when the sheet material 344 is fed by the rotation of the rotation shaft portion 342 when the transfer mechanism 340 is viewed along the rotation shaft of the rotation shaft portion 342. Means clockwise direction. In addition, the specific structure of the rotational force receiving part 326 is arbitrary, and in another example, parts other than a hexagon nut are used.

  In the illustrated example, a front wall 324 is provided at the front end of the base plate 320. The rotational force receiving portion 326 described above is provided in the hole of the front wall 324, so that contact with a care recipient is avoided. The front wall surface of the front wall 324 functions as a support surface that supports the turning of the operation tool 381.

  As can be clearly understood from FIG. 3, the seat portion 300 further includes a rotation prohibiting tool 328 for prohibiting the rotation of the rotating shaft portion 342. The rotation prohibiting tool 328 is fixed to the base plate 320. The rotation of the rotation shaft 342 is inhibited by the operation of the rotation prohibiting tool 328, and the transfer mechanism 340 can be operated to prevent the sheet material 344 from being sent in the circumferential direction when not desired. The rotation prohibiting tool 328 includes, for example, a nut receiver that fits into a hexagon nut fixed coaxially with the rotating shaft portion 342. The fitting and non-fitting states of the hex nut and the nut receiver can be switched by operating the operation member of the rotation prohibiting tool 328. In another form, another type of rotation inhibiting device is used.

  Although not necessarily limited to this, as can be clearly understood from FIG. 2, the board mounting portion 360 is provided adjacent to the transfer mechanism 340 in the left-right direction. When the sliding board 80 is attached to the board attachment portion 360, the sliding board 80 is disposed adjacent to the transfer mechanism 340 in the left-right direction. In the illustrated example, the board attachment portion 360 is provided on one of the left and right sides of the transfer mechanism 340. In another example, the board attaching part 360 is provided on both the left and right sides of the transfer mechanism 340.

  The board attachment portion 360 is a metal or resin or other material structure provided with a fitting groove 363 that opens upward in the vertical direction and extends long in the front-rear direction. The fitting protrusion 83 provided on the sliding board 80 is inserted into the fitting groove 363, whereby the sliding board 80 is attached to the board attachment portion 360. Although not necessarily limited to this, when the sliding board 80 is attached to the board attaching part 360, the sliding board 80 is placed on the upper surface of the board attaching part 360.

  The board attachment portion 360 is provided with a lock 364 for locking the sliding board 80 attached to the board attachment portion 360. In the illustrated example, the locking tool 364 locks the fitting protrusion 83 of the sliding board 80 so as not to be disengaged from the fitting groove 363 of the board mounting portion 360.

  The lock tool 364 in the illustrated example is provided on the left wall surface of the board attachment portion 360 and has a protrusion that can protrude into the fitting groove 363 through a through hole that penetrates the wall portion of the board attachment portion 360. One or more fitting holes are provided in the fitting protrusion 83 inserted into the fitting groove 363. By switching the protrusion and non-protrusion of the protrusion of the locking tool 364 in the fitting groove 363, the fitting and non-fitting of one or more fitting holes of the fitting protrusion 83 and the protrusion of the lock tool 364 can be switched. . The locking tool 364 is, for example, an index plunger. In another example, another type of locking device is used, and the sliding board 80 is locked to the board mounting portion 360 in another manner. In another example, two or more locking devices are used.

  In the illustrated example, the board mounting portion 360 is provided with a concave fitting portion, that is, a fitting groove 363, and the sliding board 80 is provided with a convex fitting portion, that is, a fitting protrusion 83. In another example, the board mounting portion 360 is provided with a convex fitting portion, and the sliding board 80 is provided with a concave fitting portion.

  As shown in FIG. 7, when the sliding board 80 is attached to the board attaching part 360, the sliding board 80 is disposed adjacent to the left side with respect to the transfer mechanism 340. The upper surface of the sheet material 344 that provides the seating surface of the seat portion 300 and the upper surface of the sliding board 80 are disposed adjacent to each other in the left-right direction in a manner that does not overlap vertically.

  When transferring, the transfer tool 40 is placed in advance on the upper surface of the sheet material 344 of the transfer mechanism 340 that provides the seat surface of the seat 300. Alternatively, the transfer tool 40 is inserted and disposed between the buttocks of the care recipient who sits on the seat 300 of the wheelchair 60 and the seat 300. Next, the transfer device 40 is pulled so as to move from the seat portion 300 to the sliding board 80 in a state where a care recipient is seated on the transfer device 40. The direction in which the transfer tool 40 is pulled is leftward in the illustrated example of FIG. However, in other examples, it can be right, forward, or rearward, or any diagonal direction that intersects the vertical direction.

  In the illustrated example, a sliding board 80 is disposed adjacent to the left side of the transfer mechanism 340. In some cases, the vertical distance between the upper surface of the sheet material 344 of the transfer mechanism 340 that provides the seating surface of the seat 300 and the upper surface of the sliding board 80 is small. In the case shown in FIG. 7, only a slight gap 52 is provided between the upper surface of the sheet material 344 that provides the seating surface of the seat portion 300 and the upper surface of the sliding board 80. Smooth movement of the transfer tool 40 between the transfer mechanism 340 and the sliding board 80 is ensured.

  In some cases, when the transfer tool 40 slides on the sheet material 344 of the transfer mechanism 340 of the seat portion 300, the sheet material 344 is entrained by the transfer tool 40. With the entrainment of the sheet material 344, the sheet material 344 is fed in the circumferential direction, and the rotating shaft portion 342 also passively rotates. Pulling the transfer tool 40 due to contact resistance between the sheet material 344 of the transfer mechanism 340 and the transfer tool 40 is avoided or reduced.

  The upper surface of the sliding board 80 is a flat surface having no irregularities. Accordingly, even after the transfer tool 40 has entered the sliding board 80, the transfer tool 40 slides smoothly. The care recipient is displaced leftward on the transfer mechanism 340 while sitting on the transfer device 40, moves from the transfer mechanism 340 to the sliding board 80, and then displaces on the sliding board 80. After moving to the bed 20, the care recipient can break the sitting position and lie on the bed.

  At the time of transfer, the sheet material 344 can be fed in the circumferential direction by manually rotating the rotary shaft portion 342 by turning the operation tool 381 described above. The force required for the initial movement of the transfer device 40 is reduced, and the burden on the caregiver who pulls the transfer device 40 is reduced. In another example, the rotational force from the electric motor is supplied to the rotational force receiver 326 described above. In such a case, labor for pulling the transfer tool 40 on the seat 300 of the wheelchair 60 is reduced. Although not necessarily limited to this, in some cases, two persons or three persons collaborating with a person who pulls the transfer tool 40, a person who rotates the operation tool 381, and optionally a person who supports the posture of the care recipient, need care. Transfer of a person can be facilitated.

  In some cases, the sheet material 344 is stretched with an appropriate tension between the pair of rotating shaft portions 342, and a comfortable seating surface is provided for the care recipient. However, when the weight of the care recipient is heavy, a downward sinking of the upper region of the sheet material 344 that provides the seating surface of the seat 300 can be manifested. In the illustrated example, in view of this point, the wheelchair 60 includes means 390 for preventing or reducing the downward sinking of the upper region of the sheet material 344. The means 390 can also be understood as a unit or structure that prevents or reduces downward sinking.

  The means 390 is disposed at a position surrounded by the endless sheet material 344. In the illustrated example, the means 390 has a leaf spring 391 as shown in FIG. 8, and prevents or reduces the downward sinking of the upper region of the sheet material 344 according to the deformation of the leaf spring 391. The leaf spring 391 can take a state or posture that protrudes upward to prevent the upper region of the sheet material 344 from sinking downward. In another example, means other than the leaf spring are employed. For example, a bag body that can be inflated by air injection is used, and this is disposed at a position surrounded by an endless sheet material 344. Even in such a case, the same effect can be obtained. The bag body can be reduced by air suction.

  In the illustrated examples of FIGS. 8 and 9, the downward sinking prevention or reduction means 390 includes a plate spring 391, a flat plate 392, a pushing member 393, a shaft 394, and a rotational force receiving portion 395. By fitting the operating tool 396 to the rotational force receiving portion 395 and turning the operating tool 396, the rotational force can be supplied to the rotational force receiving portion 395. The rotational force receiving portion 395 receives the rotational force from the operation tool 396 and advances the shaft 394. The pushing member 393 is fixed to the tip of the shaft 394, and the plate end of the plate spring 391 is pushed, and the plate spring 391 is bent into a bent shape protruding upward. The flat plate 392 pushed upward by the leaf spring 391 prevents or reduces the downward sinking of the upper region of the sheet material 344. When the operation tool 396 is turned in the opposite direction, the shaft 394 is retracted, the pushing member 393 is also retracted, and the leaf spring 391 is returned to the original shape.

  At the time of transfer, the operating tool 396 is turned to cause the leaf spring 391 to protrude upward, and the downward sinking of the sheet material 344 can be prevented or reduced. Although not necessarily limited to this, in some cases, either the person who pulls the transfer tool 40, the person who rotates the operation tool 381, or the person who optionally supports the posture of the care recipient needs to know the operation tool 396 in advance. To secure a state in which the downward sinking of the upper region of the sheet material 344 is reduced or prevented. By transferring the care recipient in this state, the physical burden on the care recipient is particularly reduced.

  The specific shape and material of the sliding board 80 can vary. The sliding board 80 in the illustrated example of FIGS. 10 and 11 includes a main board 81 bent at one place, and a board connecting portion 82 for attaching the main board 81 to the board attaching portion 360. The board connecting portion 82 is provided with the fitting protrusion 83 described above.

  The board connecting portion 82 has a distal portion 82m located at a position relatively distant from the wheelchair 60 and a proximal portion 82n located at a position relatively close to the wheelchair 60. The proximal end portion of the main board 81 is laminated on the distal portion 82m of the board connecting portion 82, and both are connected by a fastener such as a bolt and a nut. The distal portion 82m is provided with a step surface 84 that is stepped down with respect to the upper surface 88 of the proximal portion 82n. The main board 81 is placed on the step surface 84, and the upper surface of the main board 81 and the upper surface 88 of the proximal portion 82n are flush with each other. The proximal portion 82n is provided with a step surface 86 that is stepped down with respect to the lower surface 85 of the distal portion 82m. The fitting protrusion 83 protrudes downward from the step surface 86. The vertical thickness of the proximal portion 82n of the board connecting portion 82 is appropriate to reduce the vertical distance between the seating surface of the seating portion 300 and the upper surface of the sliding board 80, and more preferably to make them both flush. Can be adjusted.

  Compared with the upper surface of the main board 81, the upper surface of the board connecting part 82 may have a higher coefficient of friction. By placing the main board 81 on the distal portion 82m of the board connecting portion 82, the exposed area of the upper surface of the board connecting portion 82 is reduced. In one example, the main board 81 is made of resin, and the board connecting portion 82 is made of metal. A metal fitting protrusion 83 is fixed to the board connecting portion 82. The upper surface of the main board 81 is coated with a low friction material or coated with a low friction material. In some cases, the low-friction material is a fluorine resin, a cloth woven with fluorine fibers, or the like.

  The transfer tool 40 in the illustrated example of FIG. 12 includes a thin base 41 that has an upper surface and a lower surface and is long in one direction. FIG. 12 shows the lower surface of the thin base material 41 of the transfer tool 40. The thin substrate 41 may have a single-layer or multi-layer cross-sectional configuration. For example, the thin base material 41 includes, as a constituent layer thereof, one or more base fabrics in which high-strength fibers, for example, aramid fibers are woven. In some cases, the thin substrate 41 is flexible and can be folded or rolled. A handle opening 43 is provided at both ends 42 of the thin base material 41. The caregiver can pass the finger through the handle opening 43 and pull the transfer tool 40. In some cases, the ends 42 of the thin substrate 41 are reinforced with additional layers or structures. In another example, a handle other than the handle opening 43, for example, an arch-shaped handle is provided.

  One or more low friction materials 44 are bonded and fixed to the lower surface of the thin base material 41. In the case of the illustrated example, three low friction materials 44 are used, and each low friction material 44 extends long in the longitudinal direction of the thin base material 41. The low friction material 44 includes, for example, a fluorine fiber cloth. The fluorine fiber is a fiber made of a fluorine resin. Thereby, the sliding resistance between the transfer tool 40 and the upper surface of the sliding board 80 is reduced, and smoothing of transfer is promoted.

As can be understood from the above description, in the transfer support method for the care recipient using the sliding board 80,
(I) A sliding board 80 is attached to a wheelchair 60 having a seat 300 provided with at least one transfer mechanism 340 in which a sheet material 344 is wound endlessly around at least a pair of rotating shafts 342, and the seat The upper surface of the sheet material 344 that provides 300 seating surfaces and the upper surface of the sliding board 80 are arranged adjacent to each other in a manner that does not overlap vertically;
(II) placing the transfer tool 40 on the upper surface of the sheet material 344;
(III) including a step of pulling the transfer tool 40 so that the care recipient moves from the seat portion 300 onto the sliding board 80 in a state where the care recipient sits on the upper surface of the sheet material 344 via the transfer tool 40. .

  It is understood that (I) to (III) are unordered, and there is no restriction on the time interval between the steps. For example, step (II) or (III) is performed before step (I). In some cases, the sheet material 344 of the transfer mechanism 340 is taken to the transfer tool 40 during step (III). In another case, a rotational force is supplied from a motor or the like to the rotation shaft portion. If the rotation speed of the rotating shaft portion is low, the sheet material 344 is similarly taken to the transfer tool 40.

Moreover, when transferring a care recipient from the transfer destination, for example, from the bed 20 to the wheelchair 60, the transfer support method is:
(IV) A sliding board 80 is attached to a wheelchair 60 having a seat 300 provided with at least one transfer mechanism 340 in which a sheet material 344 is wound endlessly around at least a pair of rotating shafts 342, and the seat The upper surface of the sheet material 344 that provides 300 seating surfaces and the upper surface of the sliding board 80 are arranged adjacent to each other in a manner that does not overlap vertically;
(V) The step which pulls the transfer tool 40 so that a care recipient needs to move on the seat part 300 via the sliding board 80 from the seat part 300 outside is included.

  In another embodiment shown in FIGS. 13 to 18, the transfer tool 40 is provided with a cushion seat 46. Thereby, the uncomfortable feeling with respect to always arrange | positioning the transfer tool 40 on the seat part 300 of the wheelchair 60 is reduced, and seating comfort is also raised. As can be understood from FIG. 13, the transfer support method is understood in the same manner as the embodiment described with reference to FIGS.

  The manner in which the cushion seat 46 is incorporated into the transfer device 40 can vary. In the illustrated examples of FIGS. 14 and 15, the cushion seat 46 is fixed to the upper surface of the thin base material 41 of the transfer tool 40, particularly to the center in the longitudinal direction thereof. The upper and lower thickness of the cushion seat portion 46 is larger than the upper and lower thickness of the thin base material 41. The cushion seat portion 46 includes a foam material of any material and a covering material that covers the foam material. As a method for fixing the cushion seat portion 46 to the thin base material 41, for example, adhesion, sewing, fusion, or the like is assumed.

  In some cases, the cushion seat portion 46 is detachably attached to the thin base material 41, and the type of the cushion seat portion can be changed. For example, the cushion seat can be replaced with a toilet seat cushion having an opening at the center of the cushion seat. The thin substrate 41 and the sliding board 80 are also provided with openings. The transfer tool 40 is moved from the wheelchair 60 to the seat of the western toilet through the sliding board 80, and the care recipient also moves from the wheelchair 60 to the seat of the western toilet. The excrement falls into the western toilet through the opening of the cushion seat 46, the opening of the thin base material 41, and the opening of the sliding board 80.

  In another form, the thin base material 41 is formed in the same dimension of the cushion seat part 46, and size reduction of the transfer tool 40 is achieved. The low friction material 44 is also provided on the lower surface of the thin base material 41 of the present embodiment example, and the same effect as the embodiment example described with reference to FIGS. 1 to 12 can be obtained.

  As can be understood from FIG. 16, when the arm portion 107 is oriented in the front-rear direction, the arm portion 107 contributes to restricting the displacement of the cushion seat portion 46 in the left-right direction. In some cases, means are provided for regulating the displacement of the transfer tool 40 on the seating surface of the seat 300. This means can include, for example, fastening parts such as hook-and-loop fasteners, slide fasteners, snap buttons, buckles and the like. For example, the transfer tool 40 (for example, the thin base material 41 or the cushion seat portion 46) and the transfer mechanism 340 (for example, the sheet material 344) are connected by the fastening parts. In another example, the transfer tool 40 and the base plate 320 are connected by fastening parts. In this way, the displacement of the transfer tool 40, particularly the cushion seat 46, on the seat 300 is restricted. The circumferential displacement of the sheet material 344 can be prevented by the operation of the rotation prohibiting tool 328.

  In the exemplary embodiment described with reference to FIGS. 1 to 12, the seating comfort of the seat portion 300 of the wheelchair 60 is ensured by the sheet material 344 being stretched with an appropriate tension between the pair of rotating shaft portions 342. Is done. On the other hand, in this embodiment, a comfortable sitting comfort is ensured by the cushion seat portion 46 of the transfer tool 40. Therefore, it is allowed to reduce the sitting comfort of the seat 300 itself of the wheelchair 60. In this embodiment, as shown in FIG. 17, a structure fixed to the base plate 320, which is a flat plate 399 in the illustrated example, is used as a means 390 for reducing or preventing the downward sinking of the upper region of the sheet material 344. Thereby, the downward sinking of the cushion seat part 46 is suppressed suitably.

  The flat plate 399 is disposed at a position surrounded by the sheet material 344, as in the case described above. The flat plate 399 is positioned higher than the upper surface of the base plate 320 by a predetermined height, and is disposed to face the upper surface of the base plate 320 with a predetermined interval. The illustrated flat plate 399 is placed and fixed on the upper surface of the front wall 324 of the base plate 320 and the upper surface of the spacer portion 325 of the base plate 320.

  The thin base material 41 of the transfer tool 40 in the illustrated example is long like the embodiment described with reference to FIGS. 1 to 12, and may interfere with normal movement of the wheelchair 60. In the present embodiment, the seat portion 300 can be displaced up and down with respect to the vehicle body frame 100, and a gap exists between the base plate 320 and the vehicle body frame 100. As can be understood from FIG. 18, each end portion 42 of the thin base material 41 can be disposed below the seat portion 300 through a gap between the seat portion 300 and the vehicle body frame 100. More specifically, the end portion 42 of the thin base material 41 is disposed between the lower surface of the base plate 320 and the rod portions (the upper rod portion 102 and the upper horizontal rod portion 104) of the vehicle body frame 100.

  In some cases, each end 42 of the thin substrate 41 can be magnetically attached to the base plate 320. In other cases, each end 42 may be coupled to the base plate 320 via a fastening component.

  In the form shown in FIGS. 19 and 20, the transfer tool 40 can be divided into a first region 40j, a central region 40k, and a second region 40h. In short, the first region 40j and the central region 40k can be connected and separated by fastening parts, in the illustrated example, by a slide fastener 47. Similarly, the second region 40 h and the central region 40 k can be connected and separated by a fastening part, in the illustrated example, by a slide fastener 47.

  The first and second regions 40j and 40h are used only for pulling the transfer tool 40 during transfer, and are unnecessary in other cases. The first and second regions 40j and 40h can be connected and separated from the central region 40k by the slide fastener 47, and the normal appearance and operability of the wheelchair 60 are prevented from being disturbed. In this case as well, means for regulating the displacement of the transfer tool 40, particularly the central region 40k and the cushion seat portion 46, on the seat surface of the seat portion 300 may be provided.

  With reference to FIG. 21 thru | or FIG. 33, the transfer support method and the further form example of the wheelchair used for this, a sliding board, and a transfer tool are described. Also in this embodiment, the same transfer support method as that described for the above-described various embodiments can be implemented. That is, the transfer support method according to the present embodiment may include the above-described steps (I) to (III) and / or the above-described steps (IV) and (V). In the present embodiment example, a wheelchair, a sliding board, and a transfer tool that are configured differently from the above-described wheelchair, sliding board, and transfer tool may be used. Even in such a case, the same effects as described above can be achieved except for the effects caused by the differences.

  As can be clearly understood from the reference to FIGS. 21, 22, and 31, also in this embodiment, the upper surface of the sliding board 80 does not overlap the upper surface of the sheet material 344 that provides the seating surface of the seat 300. Can be placed adjacent to each other. Regarding the attachment of the sliding board 80 to the wheelchair 60, more specifically, the seat portion 300, in the above-described embodiment, the board attachment portion 360 is provided adjacent to the transfer mechanism 340. In this embodiment, the board attachment portion is provided. 360 is incorporated into the transfer mechanism 340. Even in such a case, the same effects as described above can be achieved except for the effects due to this difference.

  As long as the upper surface of the sliding board 80 is disposed adjacent to the upper surface of the sheet material 344 that provides the seating surface of the seat portion 300 in a manner that does not overlap vertically, the board attachment portion 360 is disposed at any of various positions. Can take any of a variety of shapes. The number of board mounting portions 360 is also appropriately determined. The board attachment part 360 may be composed of any various materials, and may include, for example, a metal plate or a resin part.

  In some embodiments including the illustrated example, the board mounting portion 360 is protruded or recessed from the constituent members of the transfer mechanism 340, and in the illustrated example of FIG. It is recessed. In some cases including the illustrated example of FIG. 22, the board attachment portion 360 is recessed in the wall portion 349 of the transfer mechanism 340. Interference with a care recipient who is seated on the seat 300, which may occur when the board attachment 360 is protruded from the wall 349 of the transfer mechanism 340, can be avoided. The sliding board 80 is provided with one or more fitting portions, and the board mounting portion 360 is provided with one or more fitted portions into which the fitting portions are fitted. The fitting part of the sliding board 80 and the fitted part of the board attaching part 360 are fitted, and the connection of the sliding board 80 and the board attaching part 360 is achieved. The connection between the sliding board 80 and the board mounting portion 360 does not allow displacement of the sliding board 80 or allows displacement of the sliding board 80 depending on the embodiment.

  In some cases including the illustrated example of FIG. 22, the transfer mechanism 340 includes one or more wall portions 349 to which the rotation shaft portion 342 is rotatably attached. One or more board attachment portions 360 are provided on the wall portion 349. In some cases including the illustrated example of FIG. 22, the transfer mechanism 340 includes two wall portions 349 to which the rotation shaft portion 342 is rotatably attached. The two wall portions 349 include a front wall portion 349m and a rear wall portion 349n. Board attachment portions 360 are provided on the left and right ends of the front wall portion 349m and the rear wall portion 349n. In some cases, the rotating shaft portion 342 is attached to the wall portion 349 via a bearing. For example, the inner ring of the bearing is fixed to the rotating shaft part 342, and the outer ring of the bearing is fixed to the wall part 349 (the reverse case is also assumed).

  Each of the front wall portion 349m and the rear wall portion 349n is a flat plate portion extending in the left-right direction, and is provided so as to sandwich the sheet material 344 wound around the rotation shaft portion 342. The front wall portion 349m and the rear wall portion 349n can regulate the displacement of the sheet material 344 in the front-rear direction. In some cases where the front wall portion 349m is made of a metal flat plate, a cooling sensation material that prevents the cooling sensation felt by the care recipient when the skin of the care recipient is in contact therewith is provided on the front surface of the front wall 349m. Can be done.

  In some embodiments, including the illustrated example, the board mount 360 is configured to allow the sliding board 80 to pivot. The position of the seat portion 300 in the vertical direction, that is, the height of the seat portion 300 can be appropriately determined by operating the lifting tool 200. However, it may be complicated to adjust the height of the seat 300 each time a care recipient is transferred. From this point of view, in some embodiments including the illustrated example, the board attachment 360 is configured to allow the sliding board 80 to pivot. The sliding board 80 can be inclined between the upper surface of the sheet material 344 that provides the seating surface of the seat portion 300 and the transfer destination, for example, the upper surface of the bed 20, so that the height of the seat portion 300 needs to be adjusted. Can be eliminated or reduced.

  In the above-described embodiment, the transfer mechanism 340 and the board attachment part 360 are not relatively displaceable with respect to the base plate 320. On the other hand, in the present embodiment, the transfer mechanism 340 and the board mounting portion 360 can be displaced relative to the base plate 320. In some cases, including the illustrated example, the transfer mechanism 340 can be displaced relative to the base plate 320. The board mounting portion 360 incorporated into the transfer mechanism 340 can also be displaced relative to the base plate 320. In such a case, the distance for pulling the transfer device 40 on which the care recipient is seated when the care recipient needs to be transferred can be shortened. In some embodiments including the illustrated example, the transfer mechanism 340 and the board attachment 360 can be displaced relative to the base plate 320 in the left-right direction.

  Unlike the above-described embodiment, the transfer mechanism 340 according to this embodiment is mounted on the base plate 320 so as to be movable. In some embodiments, including the illustrated example, the transfer mechanism 340 is mounted on the base plate 320 via one or more linear guides 371 (see FIG. 26). In some cases, the linear guide 371 extends in the left-right direction. In some cases, the linear guide 371 includes a rail and a slider that moves on the rail. The rail extends in the left-right direction. The slider moves left and right on the rail. In one example, the rail may be fixed to the base plate 320 and the slider may be fixed to the transfer mechanism 340. In another example, the rail may be fixed to the transfer mechanism 340 and the slider may be fixed to the base plate 320.

  In some embodiments including the illustrated example, the wheelchair 60 and / or the seat 300 further includes a linear actuator 372 for displacing the transfer mechanism 340 relative to the base plate 320 (see FIG. 23 and the like). . In accordance with the operation of the linear actuator 372, the transfer mechanism 340 is moved in the left-right direction. FIG. 23 shows the transfer mechanism 340 in the initial position by a solid line, and shows the transfer mechanism 340 in the left end position by a broken line. FIG. 24 shows the transfer mechanism 340 in the left end position with a solid line. In accordance with the operation of the linear actuator 372, the transfer mechanism 340 is moved closer to the transfer destination, and similarly, the care recipient sitting on the transfer mechanism 340 via the transfer tool 40 is also moved closer to the transfer destination. The distance of pulling the transfer tool 40 for the transfer of the care recipient can be shortened, and the burden of the transfer operation of the care recipient can be reduced. The same effect can be obtained when a care recipient is transferred from the transfer destination onto the wheelchair 60.

  In some embodiments including the illustrated example, the transfer mechanism 340 has a width that is larger than the minimum width Wmin61 of the pair of wheels 61 and smaller than the maximum width Wmax61 of the pair of wheels 61. As can be seen from FIG. 23, the lateral width W340 of the transfer mechanism 340 is larger than the minimum lateral width Wmin61 of the pair of left and right wheels 61 and smaller than the maximum lateral width Wmax61 of the pair of left and right wheels 61. The transfer mechanism 340 is provided over each wheel 61 when in the initial position. The left end portion of the transfer mechanism 340 is disposed on the left wheel 61, and the right end portion of the transfer mechanism 340 is disposed on the right wheel 61. Sufficient left and right width of the seating surface of the seat 300 is ensured, and stability of the care recipient when the transfer mechanism 340 moves in the left and right direction is improved.

  In some embodiments including the illustrated example, the transfer mechanism 340 is located farther leftward from the base plate 320 than the left wheel 61 when in the leftmost position (see FIG. 24). Although illustration is omitted, the transfer mechanism 340 is located farther to the right from the base plate 320 than the right wheel 61 when in the right end position. In some embodiments including the illustrated example, the transfer mechanism 340 traverses each wheel 61 in response to the operation of the linear actuator 372 and moves to the outside in the left-right direction from the wheel 61. The outer side in the left-right direction means a direction away from the center of the wheelchair 60 leftward or rightward in the left-right direction. It is also assumed that the transfer mechanism 340 crosses only one wheel 61 according to the operation of the linear actuator 372.

  Similar to the above-described embodiment, when a care recipient is transferred from the wheelchair 60 onto the bed 20, the arm 107 near the transfer destination bed 20 is oriented and fixed from the front-rear direction to the left-right direction. The arm unit 107 functions as a support for supporting the care recipient, not as an obstacle to the care recipient's movement.

  Hereinafter, it will be described in more detail with reference to the drawings. In some embodiments including the illustrated example, as shown in FIG. 22, the wheelchair 60 includes a vehicle body frame 100 in which a pair of wheels 61 is rotatably provided, and a lift frame 200 with respect to the vehicle body frame 100. 21 and a seat back 300, and more specifically, a backrest 400 that is pivotably provided with respect to a base plate 320, which will be described later. 40. Another example in which the backrest 400 is provided to be pivotable with respect to the vehicle body frame 100 instead of the seat 300 is also assumed.

  With reference to FIG.25 and FIG.26, the structural example of the seat part 300 which concerns on some examples including the example of illustration is described. The seat part 300 includes a base plate 320, a transfer mechanism 340, a linear guide 371, and a linear actuator 372. The transfer mechanism 340 is mounted on the upper surface of the base plate 320 via a linear guide 371. The linear actuator 372 is mounted or positioned with respect to the lower surface of the base plate 320. The transfer mechanism 340 is moved in the left-right direction by the linear actuator 372.

  The transfer mechanism 340 includes a pair of rotating shaft portions 342, a drive roll 343, a sheet material 344 wound endlessly around the pair of rotating shaft portions 342, a tension roll 346, an upper flat plate 347, a lower flat plate 348, and a wall portion. 349. In some cases including the illustrated example, the pair of rotating shaft portions 342, the drive roll 343, and the tension roll 346 are provided rotatably between the front wall portion 349m and the rear wall portion 349n described above. In short, the pair of rotating shaft portions 342, the drive roll 343, and the tension roll 346 are rotatably supported by the front wall portion 349m and the rear wall portion 349n. Each of the pair of rotating shaft portions 342, the drive roll 343, and the tension roll 346 has a rotating shaft along the front-rear direction. The rotation axis of each rotation shaft portion 342 exists on a common plane orthogonal to the vertical direction. The rotation axis of the drive roll 343 and the rotation axis of the tension roll 346 exist on another plane parallel to the plane on which the rotation axis of the rotation shaft portion 342 exists. In some embodiments, the axial length of the drive roll 343 and the axial length of the tension roll 346 may be different from the axial length of the rotary shaft portion 342.

  The drive roll 343 is provided between at least the pair of rotating shaft portions 342. The sheet material 344 is fed in the circumferential direction according to the rotation of the drive roll 343. The drive roll 343 engages and contacts an area other than the upper area of the sheet material 344 that provides the seating surface of the seat portion 300, for example, a lower area. The drive roll 343 rotates according to the power from the drive source 343p attached to the rear of the seat portion 300 and the rear of the base plate 320. The tension roll 346 is a roll that applies tension to the sheet material 344. The tension roll 346 also contacts a region other than the upper region of the sheet material 344, for example, the lower region. The upper flat plate 347 is surrounded by the sheet material 344. On the other hand, the lower flat plate 348 is not surrounded by the sheet material 344. The upper flat plate 347 is disposed directly below the upper region of the sheet material 344 that provides the seating surface of the seat portion 300, and prevents the sheet material 344 from sinking downward. The lower flat plate 348 faces the base plate 320. The lower flat plate 348 and the base plate 320 are coupled via the linear guide 371.

  In some cases including the illustrated example, two tension rolls 346 are provided so as to sandwich the drive roll 343. The sheet material 344 is pushed upward by the tension roll 346 between the rotation shaft portion 342 and the drive roll 343. The sheet material 344 is inclined upward from the rotation shaft portion 342 toward the tension roll 346 and is inclined downward from the tension roll 346 toward the drive roll 343. It is assumed that tension is applied to the sheet material 344 by a method other than employing the tension roll 346.

  In some cases, the convex portion and the concave portion are engaged between the sheet material 344 and the drive roll 343, thereby avoiding or suppressing the displacement of the sheet material 344 in the axial direction of the drive roll 343. Alternatively or additionally, the convex portion and the concave portion can be engaged between the sheet material 344 and the rotating shaft portion 342, and / or the convex portion and the concave portion can be engaged between the sheet material 344 and the tension roll 346.

  In the illustrated example, the linear actuator 372 is a cylinder, and the rod 372n can be displaced with respect to the cylinder body 372m. The tip of the cylinder rod 372n is connected to the lower flat plate 348 of the transfer mechanism 340 via a connector 373. The linear actuator 372 can be another type of linear actuator, such as a ball screw. In the case where the linear actuator 372 is a ball screw, the nut portion of the ball screw is connected to the lower plate 348 of the transfer mechanism 340. Another example in which one or more linear actuators 372 are employed is also envisaged.

  Base plate 320 is shaped to allow connection between linear actuator 372 and transfer mechanism 340. In the illustrated example, the linear actuator 372 and the transfer mechanism 340 are coupled in front of the base plate 320, that is, the coupling tool 373 is positioned in front of the base plate 320. In this case, the front end portion 320m of the base plate 320 is located behind the front wall portion 349m. In another example, the linear actuator 372 and the transfer mechanism 340 are coupled at the rear of the base plate 320, that is, the connector 373 is positioned at the rear of the base plate 320. In this case, the rear end portion 320n of the base plate 320 is positioned in front of the rear wall portion 349n. In yet another example, the linear actuator 372 and the transfer mechanism 340 are coupled within the opening of the base plate 320, that is, the connector 373 is positioned within the opening of the base plate 320. When the transfer mechanism 340 is in the initial position (see FIG. 23), the transfer mechanism 340 is disposed on the base plate 320, and the base plate 320 cannot be viewed from above. When the transfer mechanism 340 is at the left end position (see FIG. 24), a part of the base plate 320, that is, the right side part is exposed upward as the transfer mechanism 340 moves. When the transfer mechanism 340 is in the right end position (not shown), a part of the base plate 320, that is, the left side part is exposed upward in accordance with the movement of the transfer mechanism 340.

  The linear actuator 372 can be an electric linear actuator. The linear actuator 372 operates according to the power supplied from a drive source 372p disposed below the base plate 320, for example, an electric motor. The linear actuator 372 is attached to the base plate 320 via the bracket 372b. When the transfer mechanism 340 is in the initial position, the transfer mechanism 340 is disposed on the linear actuator 372, and the linear actuator 372 cannot be viewed from above. When the transfer mechanism 340 is at the right end position, the transfer mechanism 340 is disposed on the linear actuator 372, and the linear actuator 372 cannot be viewed from above. When the transfer mechanism 340 is at the left end position, a part of the linear actuator 372 can be viewed from above.

  In some cases including the illustrated example, the wheelchair 60 drives the first drive source 200p for driving the lifting tool 200, the second drive source 343p for driving the drive roll 343, and the linear actuator 372. A third drive source 372p and a controller 900 for controlling the drive sources 200p, 343p, 372p. Another example in which any one or two of the first to third drive sources is employed is also assumed. The wheelchair 60 may have a fourth drive source for rotating the left wheel 61 and / or a fifth drive source for rotating the right wheel 61. A configuration in which several drive sources are integrated into one drive source is also envisaged.

  The controller 900 is communicably connected to each drive unit by wire or wirelessly. The controller 900 includes various input devices such as buttons, a keyboard, a joystick, a control roller, and a control ball. A care recipient or a caregiver operates an input device of the controller 900, and the controller 900 generates various commands in response thereto. The controller 900 may be constructed based on hardware or software or both. When the controller 900 includes a voice recognition device, the controller 900 generates a control command corresponding to the voice identified by the voice recognition device. The controller 900 can be replaced by an electronic device such as a smartphone, a tablet terminal, or a smart watch.

  Each drive source 200p, 343p, 372p operates according to a command supplied from the controller 900. Each drive source 200p, 343p, 372p is an electric motor in some cases, including the illustrated example. The electric motor operates in accordance with electric power supplied from a battery or a commercial power source mounted on the wheelchair 60. The power generated by each electric motor is supplied to the lifting tool 200, the drive roll 343, and the linear actuator 372, respectively. The controller 900 individually supplies commands to the lifting tool 200, the drive roll 343, and the linear actuator 372. A care recipient or caregiver can easily set the height of the seat 300 by operating the controller 900. A care recipient or a caregiver can rotate the sheet material 344 of the transfer mechanism 340 in the circumferential direction at an appropriate timing by operating the controller 900. A care recipient or caregiver can displace the transfer mechanism 340 leftward or rightward at an appropriate timing by operating the controller 900.

  The wheelchair 60 differs from the wheelchair according to the above-described embodiment in the following points. Each upper bar portion 102 of the body frame 100 is bent at two locations in the front-rear direction. The front vertical bar 103 is curved so that its upper end faces rearward. A pair of left and right handle portions 106p and a pair of left and right brake operation portions 106r are attached to the backrest frame 410 of the backrest portion 400. The controller 900 can be hung on the upper bar portion 415 of the frame of the backrest 400.

  Unlike the embodiment described above, the arm 107 is attached to the base plate 320 of the seat 300. The arm unit 107 is pivotable about a rotation axis along the vertical direction, and takes a first posture oriented in the front-rear direction and a second posture oriented in the left-right direction, and between the first posture and the second posture. It is possible to turn. The arm part 107 includes a vertical bar part 107a extending along the vertical direction, a horizontal bar part 107b extending so as to intersect and / or orthogonally cross the vertical direction, and a connecting bar 107c that connects the vertical bar part 107a and the horizontal bar part 107b. Have. A cushioning armrest 107r is provided on the horizontal bar portion 107b. In another example, an arm portion 107 having a different shape can be used. In some cases, the height of the armrest 107r of the arm portion 107 can be adjusted.

  In the present embodiment, a sliding board 80 that is smaller than the sliding board 80 of the above-described embodiment is employed. By making the sliding board 80 small, it is allowed to make the sliding board 80 portable.

  As described above, the sliding board 80 is provided with one or more fitting portions, and the board mounting portion 360 is provided with one or more fitted portions into which the fitting portions are fitted. In some cases including the illustrated example, the fitting portion and the fitted portion are one and the other of the fitting protrusion and the fitting hole. In some cases including the illustrated example, the sliding board 80 includes first and second fitting protrusions 83m and 83n. The board attachment portion 360 has first and second fitting holes 363m and 363n into which the first and second fitting protrusions 83m and 83n of the sliding board 80 can be fitted individually. Another example in which the first and second fitting protrusions 83m and 83n are provided in the board mounting portion 360 and the first and second fitting holes 363m and 363n are provided in the sliding board 80 is also assumed.

  The position of the rotating shaft of the sliding board 80 is determined by the fitting of the first fitting protrusion 83m and the first fitting hole 363m. The second fitting hole 363n extends in an arc around the first fitting hole 363m and / or around the rotation axis of the sliding board 80. Therefore, the fitting of the second fitting protrusion 83n and the second fitting hole 363n allows the sliding board 80 to pivot as shown in FIGS.

  FIG. 29 shows a state in which the sliding board 80 is oriented along the vertical direction. FIG. 30 shows a state in which the sliding board 80 is oriented in the left-right direction perpendicular to the vertical direction. As shown in FIG. 29, the first fitting protrusion 83m is inserted into the first fitting hole 363m via the introduction port of the first fitting hole 363m opened upward, and the first fitting hole 363m opened upward. The second fitting protrusion 83n is inserted into the second fitting hole 363n through the inlet of the second fitting hole 363n. When the sliding board 80 pivots from the upright posture shown in FIG. 29 to the horizontal posture shown in FIG. 30, the sliding board 80 pivots about the rotation axis determined from the fitting of the first fitting hole 363m and the first fitting protrusion 83m. Move. When the sliding board 80 pivots, the second fitting protrusion 83n advances in the arc-shaped passage formed by the second fitting hole 363n. It is not essential for the second fitting protrusion 83n to reach the end of the arc-shaped passage formed by the second fitting hole 363n. As can be seen from FIG. 30, if the second fitting protrusion 83n reaches the terminal end of the arc-shaped passage formed by the second fitting hole 363n, the sliding board 80 takes an inclined posture inclined obliquely to the left. .

  The sliding board 80 attached to the board attaching part 360 is pivoted in the reverse direction and removed from the board attaching part 360. The attachment state of the sliding board 80 to the board attachment part 360 can be realized without a lock.

  In some cases including the illustrated example, the front board attaching portion 360 is provided on the front wall portion 349m of the transfer mechanism 340, and the rear board attaching portion 360 is provided on the rear wall portion 349n of the transfer mechanism 340. That is, in some cases, the transfer mechanism 340 includes a pair of front and rear board attachment portions 360. In some cases including the illustrated example, the plurality of fitting protrusions provided on the sliding board 80 or the board attachment portion 360 are columnar portions having different diameters. In some cases, the large-diameter fitting protrusion functions as the first fitting protrusion described above, and defines the rotation axis of the sliding board 80 together with the first fitting hole.

  In some cases including the illustrated example, the sliding board 80 has a flat main board 81 and 1 for mechanically attaching the main board 81 to the board attaching portion 360, as can be seen from FIGS. The board connecting portion 82 described above is included. When the sliding board 80 is attached to the transfer mechanism 340 as shown in FIG. 30, the upper surface of the main board 81 of the sliding board 80 is on the upper surface of the sheet material 344 of the transfer mechanism 340 that provides the seating surface of the seat portion 300. Adjacent to each other. When the sliding board 80 is attached to the transfer mechanism 340 as shown in FIG. 30, the board connecting portion 82 is disposed in front of or behind the transfer mechanism 340, and interference with the transfer mechanism 340 is avoided. In short, the front board connecting part 82 is arranged in front of the front wall part 349m, and the rear board connecting part 82 is arranged in rear of the rear wall part 349n. The sliding board 80 has a pair of board connecting portions 82 corresponding to the pair of front and rear board attaching portions 360 described above. Another form in which the sliding board 80 has only one board connecting portion 82 is also envisaged. Another configuration in which the sliding board 80 has three or more board connecting portions 82 is also envisaged.

  In some cases including the illustrated example, as shown in FIG. 31, as shown in FIG. 31, the sliding board 80 is bridged between the transfer mechanism 340 and the transfer destination, for example, the bed 20, and the transfer tool 40 (not shown). ) Or without using the transfer tool 40, a care recipient (not shown) can be sent out from the seat portion 300 onto the bed 20. The sliding board 80 is attached to the seat 300 of the wheelchair 60 in the left-right direction orthogonal to the vertical direction. Further, the arm portion 107 of the wheelchair 60 is oriented and fixed in the left-right direction from the front-rear direction orthogonal to the vertical direction. The arm 107 functions as a support that supports the back of the care recipient who is moving.

  In some cases, including the illustrated example, the sliding board 80 is pivotally attached to the wheelchair 60. The trouble of adjusting the lifting tool 200 can be avoided or reduced.

  In some cases including the illustrated example, as shown in FIG. 32, a care recipient (not shown) can send out from the seat 300 to a transfer destination, for example, the bed 20 without using the sliding board 80. . The transfer mechanism 340 and the sliding board 80 can be displaced together in the left-right direction orthogonal to the vertical direction. The transfer mechanism 340 is moved in the left-right direction perpendicular to the vertical direction by the power from the third drive source 372p. The operation of the linear actuator 372 causes the transfer mechanism 340 to be sent leftward or rightward, and the transfer mechanism 340 is allowed to be laid on the transfer destination bed 20 or the like. The use of the sliding board 80 is avoided, and the trouble of attaching the sliding board 80 is avoided.

  In some cases including the illustrated example, when the transfer device 40 is pulled, the upper region of the sheet material 344 on which the transfer device 40 is placed is pulled by the power from the second drive source 343p. Sent in the same direction as the direction. When the care recipient moves from the seat 300 to the transfer destination, for example, the bed 20, or when the care recipient moves from the bed 20 to the seat 300, the force required for the initial movement of the care recipient is reduced. The movement of the care recipient from the seat 300 to the sliding board 80 is facilitated.

  In some cases including the illustrated example, as shown in FIG. 33, the transfer tool 40 is detachably attached to the sheet material 344 of the transfer mechanism 340. For example, one of the male material and female material of the hook-and-loop fastener is provided or included in the sheet material 344. Further, the other of the male material and female material of the hook-and-loop fastener is provided or included in the transfer tool 40. The male material can be a hook and the female material can be a loop. By attaching the transfer tool 40 to the sheet material 344 of the transfer mechanism 340, slippage between the sheet material 344 of the transfer mechanism 340 and the transfer tool 40 is eliminated or reduced. As described above, when the sheet material 344 of the transfer mechanism 340 is sent by the power from the second drive source 343p, the transfer tool 40 that is attached to the sheet material 344 also moves according to the power from the second drive source 343p. The labor required for the initial movement of the care recipient from the wheelchair 60 to the transfer destination or from the transfer destination to the wheelchair 60 can be reduced.

  In some cases, including the illustrated example, the transfer tool 40 has one or more engagement regions 45 in which male material is disposed (see FIG. 33). The sheet material 344 of the transfer mechanism 340 includes a material with which a male material can be engaged. The sheet material 344 and the transfer tool 40 can be connected to each other by attaching the engagement region 45 of the transfer tool 40 to the sheet material 344 of the transfer mechanism 340. In some cases including the illustrated example of FIG. 33, the engagement region 45 is provided so as to sandwich the low friction material 44 in the center in the longitudinal direction of the transfer tool 40. In the engagement region 45, a male material, that is, an engagement protrusion is arranged two-dimensionally. The sheet material 344 has a female material affixed to the outer surface, or has a nonwoven fabric on the outer surface, or is made of a nonwoven fabric. The male material in the engagement region 45 is engaged with a female material such as a nonwoven fabric loop on the outer surface of the sheet material 344. The specific configuration and density of the male material and the female material are appropriately set by those skilled in the art.

  In some cases, the transfer device 40 is removable from the care recipient's pants or skirt. The care recipient, trousers or skirt and the upper surface of the transfer device 40 can be fastened by any of a variety of fastening means such as hook-and-loop fasteners or belts. In such a case, when the care recipient needs to take off the trousers or the skirt while sitting on the seat portion of the toilet, the transfer tool 40 is accompanied by the trousers or the skirt. The trouble of removing the transfer tool 40 from the toilet seat is eliminated or reduced.

  When a care recipient is transferred from the transfer destination, for example, the bed 20 to the wheelchair 60, the transfer support method includes the steps (IV) and (V) described above. The transfer support method may further include a step of detachably attaching the transfer tool 40 to the sheet material 344. The slip between the sheet material 344 and the transfer tool 40 is eliminated or reduced. The step of detachably attaching the transfer tool 40 to the sheet material 344 may include the step of attaching the transfer tool 40 to the upper surface of the sheet material 344. Furthermore, when the transfer tool 40 is pulled so that a care recipient moves from the outside of the seat portion 300 to the seat portion 300, the transfer device 40 is pulled in the upper region of the sheet material 344 by the power from the drive source 343p. It can be sent in the same direction as the direction. The labor required for the initial movement of the care recipient can be reduced.

  Based on the above teaching, those skilled in the art can make various modifications to the embodiments. Reference signs included in the claims are for reference only and should not be referenced for the purpose of limiting the scope of the claims. In another example, the sheet material of the transfer mechanism is fed not in the left-right direction but in the front-rear direction or the oblique direction. In another example, the sliding board is provided with an inclined surface, which makes it easier to transfer the wheelchair onto the bed. In another example, a plurality of openings are provided in the sheet material of the transfer mechanism to provide improved breathability.
