DETAILED DESCRIPTION OF THE INVENTION

[0023] An embodiment of a nursing care transfer device according to the present invention will now be described with reference to the accompanying drawings. In Figures 1 to 3, the illustrated nursing care transfer device 2 comprises a transfer device main body 4, a lifting platform 6 attached to the transfer device main body 2, and a receiving structure 8 attached to the lifting platform 6. The transfer device main body 4 functions as a base part of the nursing care transfer device 2, and a moving means 10 is provided at the bottom thereof.

[0024] The illustrated moving means 10 is composed of four movable casters 12, which are arranged at the square corners of the bottom surface of the transport device main body 4. Each movable caster 12 is constructed using a known method, and includes a mounting member 14 attached to the transport device main body 4, a fork 16 rotatably attached to the mounting member 14, and a wheel 18 rotatably supported by the fork 16. In this configuration, gripping members 20 are attached to both ends of the lifting platform 6 in the longitudinal direction (the left-right direction in FIGS. 1 and 2, and the direction perpendicular to the paper surface in FIG. 3), and the gripping portions 22 of the gripping members 20 extend diagonally upward. Note that the gripping members 20 may be provided on the transport device main body 4 instead of the lifting platform 6. With this configuration, the transport device main body 4 can be moved forward (or backward) by grasping and pushing (or pulling) the gripping portions 22 of the gripping members 20.

[0025] The lifting platform 6 is supported on the transfer device main body 4 so as to be movable up and down via a vertical slide mechanism 24 (constituting a second slide mechanism). The illustrated vertical slide mechanism 24 is made up of four lifting linear guides 26, which are well known per se, and these lifting linear guides 26 are arranged in the square sections of the transfer device main body 4. The lifting linear guides 26 are made up of a fixed side member (not shown) attached to the transfer device main body 4 and a movable side member 28 movably attached to this fixed side member, and this movable side member 28 is attached to the lifting platform 6.

[0026] As the up-down slide mechanism 24, a well-known slide mechanism (not shown) can be used instead of the lifting linear guide 26, with one side member (fixed side member) of the slide mechanism attached to the transfer device main body 4 side and the other side member (movable side member) attached to the lifting and lowering platform 6 side.

[0027] A lifting cylinder mechanism 30 (see, for example, FIG. 10 ) is disposed between the transfer device main body 4 and the lifting platform 6, and this lifting cylinder mechanism 30 is provided, for example, at one side and the other side in the longitudinal direction of the transfer device main body 4 (for example, at the portion supporting the head side and the portion supporting the foot side of the care recipient) at an interval. The lifting cylinder mechanism 30 is constituted, for example, by an electric cylinder mechanism, and its cylinder body 32 is attached, for example, to the upper surface of the transfer device main body 4, and its output rod 34 is attached, for example, to the bottom surface of the lifting platform 6. Note that instead of the electric cylinder mechanism 30, a pneumatic cylinder mechanism using compressed air may be used as the lifting cylinder mechanism 30, or the lifting cylinder mechanism 30 may be omitted and a screw-fit structure may be adopted so that the lifting and lowering is performed manually or electrically.

[0028] Because of this configuration, when the pair of lifting cylinder mechanisms 30 extend in sync, the lifting platform 6 rises upward along the up-and-down slide mechanism 24 (lifting linear guide 26) and is positioned at the raised position (position shown in Figure 4), and when the lifting cylinder mechanisms 30 contract in sync, the lifting platform 6 descends and is positioned at the lowered position (position shown in Figure 3).

[0029] 1 and 5, a plurality of accommodating recesses 36 are provided on the surface (upper surface) of the lifting platform 6 at intervals in the longitudinal direction, and these accommodating recesses 36 extend from one side to the other side in the width direction of the lifting platform 6 (the vertical direction in FIG. 1, the direction perpendicular to the paper surface in FIG. 2, and the horizontal direction in FIG. 3). These accommodating recesses 36 of the lifting platform 6 accommodate support receiving portions 56 of the receiving structure 8, which will be described later (see FIG. 1).

[0030] Next, the receiving structure 8 will be described. The receiving structure 8 shown in the figure includes a movable support main body 40 attached to the lifting platform 6, a receiving body 42 attached to the movable support main body 40, and a swivel support 44 for covering one side of the receiving body 42 (the upper side in FIG. 1 and the right side in FIG. 3). The movable support main body 40 includes a pair of support main body parts 46, 48 spaced apart in the longitudinal direction of the transfer device main body 4, with one support main body part 46 slidably supported on one end of the lifting platform 6 via one lateral slide mechanism 50 (see FIGS. 2 and 5) (forming part of the first slide mechanism), and the other support main body part 48 slidably supported on the other end of the lifting platform 6 via the other lateral slide mechanism 52 (see FIGS. 2 and 5) (forming part of the first slide mechanism). These lateral slide mechanisms 50, 52 are constituted by, for example, lateral movement linear guides, the fixed side member of which is attached to the transfer device main body 4 side, and the movable side member of which is attached to the receiving structure 8 side.

[0031] A support pillar portion 54 having a rectangular cross section is arranged between the pair of support main body portions 46, 48, and on the other side of the receiving body 42, one end thereof is attached to one support main body portion 46 and the other end thereof is attached to the other support main body portion 48, and this support pillar portion 54 extends linearly in the longitudinal direction of the transfer device main body 4.

[0032] The support column 54 is provided with a plurality of support receiving portions 56 spaced apart in its axial direction (i.e., the longitudinal direction of the transfer device main body 4), and the plurality of support receiving portions 56 are provided corresponding to the plurality of storage recesses 36 on the upper surface of the lifting platform 6. As shown in FIGS. 7 and 8, the plurality of support receiving portions 56 are generally plate-shaped, with one end attached to the support column 54 and the distal end thereof curving downward in a concave shape and then extending horizontally, with the distal end formed in a semicircular shape (see FIG. 5). The support receiving portions 56 may have any suitable shape for placing and supporting the care recipient, and may, for example, extend linearly from the support column 54 toward the distal end, and the distal end may also have any suitable shape that allows for easy insertion, such as a semi-elliptical shape.

[0033] Between the pair of support main body parts 46, 48, there is further rotatably attached a swivel support body 44, which is equipped with a swivel member 57 that can be swiveled up and down. The swivel member 57 has a pair of arm parts 58, 60 and a grip part 62 that connects the tip ends of the pair of arm parts 58, 60, with the base part of one arm part 58 rotatably connected to the inside of the attachment part of the support pillar part 54 on one support main body part 46, and the base part of the other arm part 60 rotatably connected to the inside of the attachment part of the support pillar part 54 on the other support main body part 48.

[0034] The gripping portion 62 of the swivel support body 44 is provided with a plurality of (five in this embodiment) connecting portions 64 corresponding to some specific support receiving portions 56a (five support receiving portions located in the longitudinal center region in this embodiment) of the plurality of support receiving portions 56. Each connecting portion 64 extends downward at an inward angle from a base portion attached to the gripping portion 62 of the swivel member 57, and has an insertion connecting hole 66 at its tip portion (see, for example, FIG. 10).

[0035] In this embodiment, the pair of arms 58, 60 are further provided with extensions 68 that expand and contract in the axial direction. Although the structure of the extensions 68 is not shown, the extensions 68 are held in a contracted state by the action of a coil spring, for example, and can be extended by pulling against the action of the coil spring.

[0036] Because of this configuration, the swivel support body 44 can freely rotate up and down between an upper swivel angle position (the angle position shown by the dashed line in FIGS. 7 and 8) and a lower swivel angle position (the angle position shown by the solid line in FIGS. 7 and 8). When the swivel support body 44 is in the upper swivel angle position, the pair of arms 58, 60 of the swivel support body 44 extend obliquely upward, thereby opening one side of the receiving body 42 and creating a receiving opening 70 (see FIG. 10) between the receiving body 42 and the swivel support body 44 for receiving the care recipient.

[0037] Furthermore, when the swivel support body 44 is in the lower swivel angle position, the swivel member 57 of the swivel support body 44 extends horizontally, and the gripping portion 62 of the swivel member 57 and the multiple connecting portions 64 attached thereto block the receiving opening 70 on one side of the receiving body 42. When held in this lower swivel angle position, the multiple support receiving portions 56 of the receiving body 42 and the swivel member 57 of the swivel support body 44 and the connecting portions 64 attached thereto form a receiving placement portion for placing and supporting the person being cared for, and one side of this receiving placement portion is defined by the swivel member 57 and the multiple connecting portions 64, and the other side and bottom are defined by the multiple support receiving portions 56 of the receiving body 42.

[0038] Although not shown, an upper rotation prevention means (e.g., an upper rotation abutment) can be provided to prevent the rotation of the rotating support 44 (rotating member 57) from exceeding the upper rotation angle position, and a lower rotation prevention means (e.g., a lower rotation abutment) can be provided to prevent the rotation from exceeding the lower rotation angle position.

[0039] In this embodiment, the length of the multiple support receiving portions 56 located on the central side is longer than the lengths of the multiple support receiving portions 56 located on either side, but the lengths of the multiple support receiving portions 56 may also be the same, and although the connecting portions 64 are provided corresponding to specific support receiving portions 56a of some of the multiple support receiving portions 56, for example, connecting portions 64 may also be provided for all of the multiple support receiving portions 56.

[0040] When the gripping portion 62 of the swivel support 44 is pulled in the direction indicated by arrow 72 (see Figures 5, 7 and 8) and rotated to the lower swivel angle position, the extension portions 68 of the pair of arm portions 58, 60 extend to the state shown by solid lines in Figures 7 and 8, and the connecting portion 64 attached to the swivel member 57 is positioned outside the multiple support receiving portions 56 of the receiving body 42 (in this case, the specific support receiving portion 56a).By configuring in this way, the swivel support 44 is allowed to rotate to the lower swivel angle position.

[0041] 7 and 8, when the hand is released from the gripping portion 62 of the swivel member 57, the extension portions 68 of the pair of arms 58, 60 contract, and the multiple connecting portions 64 move together with the gripping portion 62 toward the multiple support receiving portions 56, so that the tip ends of the specific support receiving portions 56a on the receiver 42 side are inserted and connected into the insertion and connection holes 66 of these connecting portions 64. In this inserted and connected state, the base sides of the multiple specific support receiving portions 56a are supported by the support column portion 54, and their tip ends are supported by the connection portion 64 of the swivel support body 44, so that these specific support receiving portions 56a are supported at both ends, which provides sufficient strength to the receiving structure 8 and allows the care recipient to be safely placed and supported.

[0042] Furthermore, instead of such an insertion connection hole 66, for example, an engagement connection structure may be adopted. In this case, the engagement connection structure includes a plurality of engagement members that can be engaged and connected to the support receiving portion 56 in a freely detachable manner, and by engaging and connecting the multiple engagement members to the tip portions of the corresponding support receiving portions 56, the receiving body 42 and the swivel support body 44 can be engaged and connected in a freely detachable manner.

[0043] Furthermore, since the movable support body 40 (a pair of support body portions 46, 48) can be freely moved laterally via a pair of lateral slide mechanisms 50, 52, for example, by manually moving the movable support body 40 (or the swiveling member 57), the movable support body 40 (the receiving body 42 and swiveling support body 44 attached thereto) can be moved laterally between the storage position (the position shown in Figure 1, which is located on the upper surface of the lifting platform 6) and the receiving position (the position shown in Figure 5, which protrudes to the side of the lifting platform 6).

[0044] When the movable support body 40 (receiving body 42 and supporting swiveling body 44) is positioned in the storage position, as shown in Figure 1, the multiple support receiving portions 56 (specifically, their horizontally extending portions) of the receiving body 42 are accommodated in the accommodating recesses 36 of the lifting platform 6, and the upper surfaces of these support receiving portions 56 are substantially flush with the upper surface of the lifting platform 6. By configuring in this manner, the care recipient can be gently placed and supported.

[0045] Furthermore, when this movable support body 40 (receiving body 42 and supporting rotating body 44) is positioned at the receiving position, as can be seen from Figure 5, the multiple support receiving portions 56 of the receiving body 42 are positioned laterally outside the liftable platform 6, and by configuring it in this manner, the person being cared for who is lying on the bed can be positioned above these support receiving portions 56 and placed and supported on these support receiving portions 56 as described below.

[0046] Although not shown, a first movement preventing means (e.g., a first moving abutment portion) can be provided to prevent the moving support body 40 (receiving body 42 and support rotating body 44) from moving beyond the receiving position, and a second movement preventing means (e.g., a second moving abutment portion) can be provided to prevent the moving support body 40 from moving beyond the storage position.

[0047] In this nursing care transfer device 2, as shown in Figures 2, 3, 7 and 8, a pair of support legs 82, 84 are arranged facing each other on the bottom (in this embodiment, the bottom surface) of the transfer device main body 4, with one support leg 82 being provided on one end side of the transfer device main body 4 and the other support leg 84 being provided on the other end side, and these support legs 82, 84 having substantially the same structure.

[0048] The support leg 82 (84) comprises a swivel arm 86 rotatably mounted on the bottom of the transfer device main body 4, and a leg 88 attached to the tip of the swivel arm 86, and the leg 88 is configured to be movable up and down by, for example, an electric cylinder 90. The swivel arm 86 of the support leg 82 (84) is rotatable in the horizontal direction between a storage angle position (angle position shown in Figures 2 and 3) in which it is stored below the transfer device main body 4, and a support angle position (angle position shown in Figures 7 and 8) in which it protrudes laterally outward from the transfer device main body 4.

[0049] The swivel arm portion 86 of the support legs 82, 84 is configured to be swiveled directly by hand, but it may also be possible to provide an operating handle or the like and rotate the operating handle to cause the swivel, or to provide a swivel drive motor and operate the swivel drive motor to cause the swivel.

[0050] 2, 3, and 5, when the swivel arm portions 86 of the support legs 82, 84 are swung inward in a direction that brings them closer to each other and positioned at the storage angle position, the swivel arm portions 86 and legs 88 are positioned below the transfer device main body 4 and can be compactly stored below the transfer device main body 4. When the swivel arm portions 86 are swung outward in a direction that moves them away from each other and positioned at the support angle position, the swivel arm portions 86 are positioned at a position that extends laterally from the transfer device main body 4, as shown in Figures 7 and 8, and the swivel arm portions 86 and legs 88 function as supports to prevent tipping over when the care recipient is placed and supported on the receiving structure 8.

[0051] When the electric cylinders 90 of the support legs 82, 84 are contracted, the legs 88 are positioned at an elevated position above the floor F, as shown in Figures 2 to 4, and by holding the legs 88 at the elevated position, the swivel arm 86 is permitted to pivot toward the storage angle position and the support angle position. When the electric cylinders 90 are extended, the legs 88 are lowered to a lowered position, as shown in Figures 7 and 8, and by holding them at the lowered position, the legs 88 come into contact with the floor F and can support the transfer device main body 4, thereby reliably preventing the transfer device main body 4 from tipping over.

[0052] Although not shown, in relation to the support legs 82, 84, a first rotation prevention means (e.g., a first rotation abutment) can be provided to prevent the rotation of these rotation arm portions 86 beyond the storage angle position, and a second rotation prevention means (e.g., a second rotation abutment) can be provided to prevent the rotation of these rotation arm portions 86 beyond the support angle position.

[0053] Next, mainly with reference to Figures 9 to 16, the transfer of a care recipient using the above-mentioned care transfer device 2 will be described. In Figure 9, to transfer a care recipient P lying on a bed 102, the above-mentioned care transfer device 2 is moved to the side of the bed 102 (see also Figure 1). When using this care transfer device 2, it is necessary to insert the tip ends of the multiple support receiving portions 56 of the care transfer device 2 between the upper surface of the bed 102 and the care recipient P, as will be described later. Therefore, an air mattress 104 is laid on the upper surface of the bed 102, and the care recipient P lies on this air mattress 104.

[0054] 9, the air mattress 104 is described. The air mattress 104 comprises a plurality of first support pouches 106 and a plurality of second support pouches 108, which are arranged alternately in the longitudinal direction of the air mattress 104 (the left-right direction in FIG. 9). The plurality of second support pouches 108 are provided corresponding to the plurality of support receiving portions 56 of the nursing care transfer device 2, and the width of the second support pouches 108 is configured to be slightly larger than the width of the plurality of support receiving portions 56 (including the specific support receiving portion 56a).

[0055] In this embodiment, the widths of the multiple first support bag portions 106 and the multiple second support bag portions 108 are the same, but for example, the width of these second support bag portions 108 may be made slightly larger than the first support bag portions 106.If configured in this way, the width of the multiple support receiving portions 56 of the receiving body 42 can be made slightly larger to increase its strength.

[0056] In this air mattress 104, the multiple first support bags 106 are connected to one another via a first air flow path (not shown), and the multiple second support bags 108 are connected to one another via a second air flow path (not shown). Also, for example, the first air flow path is connected to a compressed air supply source (e.g., an air pump) (not shown) via a first flow path switching valve (not shown), and the second air flow path is connected to the compressed air supply source via a second flow path switching valve (not shown).

[0057] When the air mattress 104 is in use, the compressed air supply source is connected to the first air flow path through the first flow path switching valve and to the second air flow path through the second flow path switching valve. In this state, compressed air from the compressed air supply source is supplied to the first support bags 106 through the first flow path switching valve and the first air flow path, and this compressed air inflates the first support bags 106, maintaining them in an inflated state. Compressed air from the first compressed air supply source is also supplied to the second support bags 108 through the second flow path switching valve and the second air flow path, and this compressed air inflates the second support bags 108, maintaining the entire air mattress 104 in an inflated state. Therefore, the first and second support bags 106, 108 are maintained in the positions shown by the solid lines in FIG. 9 , allowing the care recipient P to lie down comfortably on the air mattress 104.

[0058] Furthermore, when transferring the care recipient P lying on the bed 102, the multiple second support bags 108 are opened to the atmosphere through the second air flow path and the second flow path switching valve, and the compressed air in these second support bags 108 is discharged into the atmosphere through the second flow path switching valve. At this time, the multiple first support bags 106 are kept in an expanded state by the compressed air, but the multiple second support bags 108 become deflated as shown by the dashed dotted lines in Fig. 9 due to the discharge of the compressed air, and a gap 110 is generated above the deflated second support bags 108 (i.e., between the second support bags 108 and the care recipient P).

[0059] In this embodiment, the air mattress 104 is configured to be used by switching between a fully inflated state in which the first and second support bag portions 106, 108 are inflated, and a first partially inflated state in which the second support bag portion 108 is inflated (at this time, the first support bag portion 106 is in a deflated state).In addition to these states, it can also be configured to be in a second partially inflated state in which the first support bag portion 106 is inflated (at this time, the second support bag portion 108 is in a deflated state).If configured in this way, by switching the air mattress 108 between the first partially inflated state and the second partially inflated state, it is possible to prevent bedsores and the like in the person being cared for.

[0060] When transferring the care recipient P, the compressed air is released from the second support bag 108 of the air mattress 104, and in this state, the care transfer device 4 is brought close to the side of the bed 102. At this time, as shown in Fig. 10, the swivel arm portions 86 of the support legs 82, 84 are held in the support angle position, and the legs 88 are held in the raised position. Also, the lifting platform 6 is held in the lowered position, the receiving structure 8 (receiving body 42 and swivel support 44) is held in the receiving position, and the swivel support 44 is held in the upper swivel angle position.

[0061] 11 , the tip ends of the multiple support receiving portions 56 of the receiving body 42 of the nursing care transfer device 2 are inserted into the space above the deflated second support bag portion 108 of the air mattress 104 on the bed 102 (i.e., the gap 110 between the deflated second support bag portion 108 and the care recipient P lying on the air mattress 104), and the transfer device main body 4 is brought close to the bed 102. In this way, the multiple support receiving portions 56 of the receiving body 42 of the nursing care transfer device 2 are inserted between the air mattress 104 and the care recipient P. At this time, the swivel arm portions 86 of the support legs 82, 84 of the nursing care transfer device 2 are inserted into the space below the bed 102.

[0062] In the above explanation, the sheet covering the air mattress 104 has been omitted, but when a sheet S is laid on the air mattress 104, the multiple support receiving portions 56 of the receiving body 42 are inserted above the sheet S, for example, as shown in Figure 12.

[0063] In Figure 12, when a sheet S is laid on the surface side of the air mattress 104 as shown in Figure 12(a), when the multiple support receiving portions 56 of the receiver 42 are inserted, the pair of lifting cylinder mechanisms 30 are slightly extended, whereby the lifting platform 6 is positioned slightly higher than the above-mentioned lowered position as shown in Figure 12(b), and in this slightly elevated position, the transfer device main body 4 is moved to move the tips of the multiple support receiving portions 56 to above one side of the air mattress 104.

[0064] Thereafter, the pair of lifting cylinder mechanisms 30 are slightly contracted, thereby lowering the lifting platform 6 to the lowered position as shown in Figure 12(c). This downward movement causes the tips of the multiple support receiving portions 56 to press down on the sheet S on the surface side of the air mattress 104, and with the multiple support receiving portions 56 and a portion of the sheet S contained within the deflated gap 110, the multiple support receiving portions 56 of the receiving body 42 are inserted between the air mattress 104 (the sheet S on top thereof) and the person being cared for P.

[0065] Furthermore, it is preferable that the sheet S itself has sufficient elasticity so that when the sheet S is pressed down by the multiple support receiving portions 56, a portion of it can be accommodated as required within the upper gap 110 of the second support bag portion 108, and so that the multiple support receiving portions 56 can be inserted even when the sheet S is pressed down.

[0066] 13, the electric cylinders 90 of the support legs 82, 84 are extended, and the legs 88 are moved downward to their lowered positions so as to contact the floor F. This contact allows the care transfer device 2 to be stably supported on the floor. The gripping portion 62 of the swivel member 57 is then grasped and rotated downward to position the support swivel body 44 at its lowered pivot angle, and the tip of the specific support receiving portion 56a of the receiver 42 is inserted and connected to the insertion and connection hole 66 of the connection portion 64 of the gripping member 57. As can be seen from FIG. 13, this insertion and connection creates a widthwise recessed receiving and placement portion on the upper surface of the receiving structure 8, and the care recipient P is placed and supported on this receiving and placement portion, thereby preventing the care recipient P from falling from the receiving structure 8 (the receiver 42 and the swivel support body 44).

[0067] 14 and 15, the pair of lifting cylinder mechanisms 30 are extended to position the lifting platform 6 in the raised position. This causes the receiving structure 8 (receiving body 42 and swivel support body 44) to rise together with the lifting platform 6, and the support receiving portions 56 of the receiving body 42 lift the care recipient P lying on the air mattress 104 upward, thereby lifting the care recipient P from the bed 102 (air mattress 104 and sheets S). At this time, the receiving structure 8 is positioned protruding laterally from the transfer device main body 4 and is unstable. However, because the legs 88 of the swivel arms 86 of the support legs 82, 84 are in contact with the ground below the receiving structure 8, the transfer device main body 4 does not tip over, and the care recipient P can be stably placed and supported within the receiving structure 8.

[0068] 16, the swivel support 44 is pushed toward the transfer device main body 4 to position the receiving structure 8 (receiving portions 42 and swivel support 44) in the storage position, and by positioning it in this storage position, the care recipient P can be transferred from the bed 102 to the care transfer device 2. In this storage position, the multiple support receiving portions 56 of the receiving body 42 are received in the receiving recesses 36 of the lift-up platform 6 and are substantially flush with the upper surface of the lift-up platform 6, so that the care recipient P can be stably placed and supported on the upper surface of the lift-up platform 6.

[0069] When the care transfer apparatus 4 is to be moved to another location with the care recipient P placed thereon, the electric cylinders 90 of the support legs 82, 84 are contracted to position the legs 88 in the raised position, and then the swivel arms 86 are rotated inward to position them in the stored angle position, thereby permitting movement of the care transfer apparatus 2. Furthermore, the lifting cylinder mechanism 30 is contracted to position the lifting platform 6 in the lowered position, thereby lowering the position at which the care recipient P is placed, allowing the care transfer apparatus 4 to be moved stably with the care recipient P placed thereon.

[0070] Furthermore, when returning the care recipient P who is placed and supported on the care transfer device 4 to the bed 102, the above-described procedure can be reversed, and the care recipient P can be safely returned to the bed 102 (and the air mattress 104 thereon).

[0071] Although one embodiment of the nursing care transfer device according to the present invention has been described above, the present invention is not limited to this embodiment, and various changes and modifications can be made without departing from the scope of the present invention.
