First, the background of the present invention will be explained.
For elderly people or disabled people (hereinafter referred to as care recipients) who use wheelchairs, for example, transferring from a bed to a wheelchair or from a wheelchair to a chair is a necessary transfer action in daily life. For example, in care settings such as nursing care facilities, it is necessary for caregivers to frequently assist in transferring a cared person, which increases the burden on the caregiver. Therefore, there is a growing need to reduce the burden on caregivers.
On the other hand, in today's nursing care settings, transfer devices designed to reduce the burden on caregivers are not as widespread as wheelchairs. Reasons why transfer devices are not popular include, for example, the time and effort required to get the cared person on and off the transfer device, the risk of the cared person falling from the transfer device, or the fact that the transfer device is expensive. There are certain points that can be mentioned. Therefore, caregivers assist the cared person in transferring the cared person without using a transfer device, which places a physical and mental burden on the caregiver.
Therefore, it is cheaper than existing transfer devices, allows caregivers to assist in transfer operations easily and quickly, and is also easy for caregivers to cling to (in other words, caregivers can intuitively use a piggyback posture to help with transfers). We have developed a new transfer device that is easy to operate, allows the care recipient to take a piggyback position, and provides a sense of security.

Next, embodiments of the present invention will be described.
The configuration of an embodiment according to the present invention will be described with reference to the drawings. However, the scope of the present invention is not limited to the illustrated example.

The upper body support member 10 is made of an elastic material at least at a position where it contacts a part of the upper body of the care recipient. This disperses the pressure (body pressure) applied to the torso of the cared person in the area that is in direct contact with the cared person. The upper body support member 10 of this embodiment is made of an elastic material in the range where the head, torso, and upper limbs of the cared person come into contact.
Further, the upper body support member 10 of the present embodiment is composed of an upholstery material that comes into direct contact with the body of the care recipient, a cushioning material that is an elastic material, and a base material. The upholstery material is, for example, synthetic leather fabric (for example, polyvinyl chloride fabric, urethane fabric, polyamide fabric), pile fabric (for example, moquette fabric), knitted fabric (for example, tricot fabric or knit fabric), or fiber. It is a material such as woven fabric (for example, plain weave fabric or Kobran woven fabric).

The leg body 50 is a leg provided with casters 52 and a footrest 54. The legs 50 may be grid-like legs or radial legs. The leg body 50 of this embodiment includes casters 52 at the four corners of a lattice-shaped frame, and a footrest 54 at the center of the lattice-shaped frame. Moreover, all the casters of the legs 50 may be of the same size, or some of them may be of different sizes. The casters of the legs 50 of this embodiment are different in size from casters 52A on the front side of the cared person when riding on the transfer device 1 to casters 52B on the rear side of the cared person. The size of the caster 52A is larger than the size of the caster 52B. For example, the size of the wheels of caster 52A is two to three times the size of the wheels of caster 52B. In addition, in the casters 52 in this embodiment, the wheel diameter of caster 52A is 10 cm, and the wheel diameter of caster 52B is 5 cm.
As a result, the caregiver can, for example, insert the casters 52B on the rear side of the cared person into the gap under the bed, etc., and move the upper body support member 10 and the lower body support member 20 closer to the bed. A person can be transferred to the transfer device 1.
As described above, the transfer device 1 according to the present embodiment includes an upper body support member 10, a lower body support member 20, a holding arm 30, a pillar 40, and a leg body 50.

Next, the operation of the transfer device 1 will be explained.
FIG. 3 is a diagram illustrating the operation of the transfer device 1 in the first embodiment. FIG. 3(A) is a diagram illustrating a state in which the upper body support member 10 is rotated rearward, and FIG. 3(B) is a diagram illustrating a state in which the upper body support member 10 is rotated forward.
As illustrated in FIGS. 3(A) and 3(B), in the transfer device 1, the upper body support member 10 and the lower body support member 20 rotate relative to each other via the holding arm 30. In other words, in the transfer device 1, the upper body support member 10 rotates with respect to the lower body support member 20. The inclination angle of the upper body support member 10 with respect to the front-rear direction of the cared person changes as the upper body support member 10 rotates. Specifically, the inclination angle of the upper body support member 10 is greater than the inclination angle Y when the upper body support member 10 is located on the front side compared to the inclination angle Z when the upper body support member 10 is located on the rear side. becomes larger. In other words, the cared person assumes a forward leaning posture (bending forward).
In this way, unlike conventional transfer devices, the transfer device 1 does not rotate the cared person in the front-rear direction to take a forward-leaning posture. Since the cared person is made to lean forward, the cared person can rest on the upper body support member 10 with peace of mind.

Next, a method of using the transfer device 1 in Example 1 will be explained. In order to explain how to use the transfer device 1, a case where a person is transferred from a bed to the transfer device 1 will be explained as a specific example.
FIG. 4 is a flowchart illustrating a method of using the transfer device 1 according to the present embodiment (S10) in Example 1, and FIG. 5 is a diagram illustrating a method of using the transfer device 1 in Example 1.
As illustrated in FIG. 4, in step 100 (S100), the caregiver puts clothing on the upper body support member 10. By putting clothes on the upper body support member 10, the upper body support member 10 can be anthropomorphized. Clothes worn on the upper body support member 10 include clothes and hats. This clothing may be, for example, the cared person's own clothing, or the clothing of a relative or spouse of the cared person. Clothing can be expected to contribute to the recovery of the care recipient's cognitive function, mental care, etc., for example. Furthermore, even if the clothes the caregiver wears become soiled, they can be easily replaced, so the cover can be used as a replacement cover.

In step 102 (S102), the caregiver adjusts the height of the bed at the transfer source and the height of the support surface 20A of the lower body support member 20 of the transfer device 1 at the transfer destination to be the same height. When the height of the bed is, for example, about 40 cm from the floor, the caregiver operates the hydraulic adjustment lever to adjust the pressure on the pillar 40 to adjust the height of the support surface 20A of the lower body support member 20. Adjust the height to about 40 cm, which is approximately the same height as the bed.

In step 104 (S104), the caregiver hugs the cared person to the upper body support member 10.
Specifically, as illustrated in FIG. 5(A), the caregiver makes the cared person sit diagonally with respect to the bed. The longitudinal direction of the lower body support member 20 and the insertion direction of the lower body support member 20 are in the same direction so that the caregiver can insert the lower body support member 20 between the bed and the cared person who is sitting diagonally. Arrange the transfer device 1 as shown.
As illustrated in FIG. 5(B), the caregiver rotates the upper body support member 10 toward the front side of the cared person using the angle changing part 34 of the holding arm 30, and then rotates the lower limbs of the cared person and the bed. The lower body support member 20 is inserted between.
As illustrated in FIG. 5(C), the caregiver inserts the lower body support member 20 between the lower limbs of the cared person and the bed, and rotates the upper body support member 10 backward. The upper body support member 10 is brought into contact with the cared person. Thereby, the cared person is hugged to the upper body support member 10.

As illustrated in FIG. 4, in step 106 (S106), the caregiver places the cared person, who is hugging the upper body support member 10, on the lower body support member 20.
Specifically, as illustrated in FIG. 5(D), the caregiver rotates the upper body support member 10 hugging the cared person, and supports the lower body while pulling the cared person at the same time. Place it on the member 20. Further, the caregiver raises and lowers the upper body support member 10 using the height adjustment part 32 of the holding arm 30, and inserts the protrusion part 16 of the upper body support member 10 between the thighs of the cared person. This prevents the cared person riding on the lower body support member 20 from slipping down to the front side of the cared person. Further, the caregiver supports the back of the cared person using the belt 80 as necessary.
In this way, the caregiver can transfer the cared person from the bed to the transfer device 1 with clothes on.

As explained above, according to the transfer device 1 of this embodiment, the caregiver can efficiently assist in transferring the cared person.
The transfer device 1 tilts the upper body support member 10 toward the front side of the cared person as the upper body support member 10 rotates, so that the cared person naturally bends forward while twisting the waist. It can be. This allows the cared person to use the transfer device with peace of mind without fear.
In addition, in the transfer device 1, by putting clothes on the mannequin-shaped upper body support member 10, it can be expected that the cared person will be able to imagine a piggyback ride, and that the care recipient will naturally hug the upper body support member 10.
Although the embodiments according to the present invention have been described above, the embodiments are not limited to these, and various changes and additions can be made within the scope of the spirit of the invention.

The upper body support member 10 also includes a pressure detection section 18 that detects pressure applied by the cared person, and a heartbeat detection section 19 that detects the heartbeat of the cared person in a supported state.
The pressure sensing portion 18 is made of an elastic material, and has a mesh-like surface.
The heartbeat detection unit 19 is disposed on the support surface of the upper body support member 10 at a position close to the heart of the supported cared person.

The head support part 14 is formed in a size large enough to support the head of the cared person. The head support part 14 can be moved in the front-rear direction of the cared person and can change its position. By changing the position, the head support section 14 can be tilted toward either the front side or the rear side of the upper body support member 10 that supports the cared person. Further, the head support section 14 includes the pressure detection section 18 described above and a camera 16 (not shown) that photographs the moving direction of the transfer instrument 102.

The holding arm 30 is located on the left side of the cared person in the supported state. The holding arm 30 located on the left side of the cared person connects the left end of the upper body support member 10 and the left end of the lower body support member 20.
Further, angle changing portions 34 are arranged at the connection position where the holding arm 30 and the upper body support member 10 are connected, and at the connection position where the holding arm 30 and the upper and lower body support member 20 are connected. The holding arm 30 is rotatably connected to the upper body support member 10 via the angle changing section 34A. The angle changing section 34A can change the angle of the upper body support member 10 in the front-rear direction of the cared person in a supported state. Further, the holding arm 30 is rotatably connected to the lower body support member 20 via the angle changing part 34B. The angle changing section 34B can change the angle and position of the upper body support member 10 in the front-rear direction of the cared person in a supported state.

The back support member 60 is arranged on the right side of the cared person in the supported state, in other words, at the right end of the upper body support member 10 as seen from the transferred cared person. The back support member 60 is rotatably connected to the upper body support member 10 via the angle changing section 35A. Thereby, the back support member 60 can change the position of the back support member 60 in the front-rear direction of the cared person in a supported state, that is, the position between the front side and the rear side of the upper body support member 10.

As described above, the transfer device 102 in the second modification changes the angle of the upper body support member 10 through the angle changing unit 34, thereby changing the surface supporting the chest and abdomen of the cared person to either the front side or the rear side. You can choose either. As a result, when the transfer device 102 supports the chest and abdomen of the cared person on the front side of the upper body support member 10, the support arm 30 is placed on the right side of the cared person. The patient can be approached from the right side and transferred. Furthermore, when the transfer device 102 supports the chest and abdomen of the cared person on the rear side of the upper body support member 10, the support arm 30 is disposed on the left side of the cared person. You can approach and transfer from the left side.
Further, the transfer device 102 in the second modification has the holding arm 30 and the back support member 60 disposed at the right end and the left end of the upper body support member 10, respectively, so that the back of the person carrying the burden is supported. I hope it will remind you. Therefore, the cared person who imagines a piggyback ride can intuitively transfer the cared person so as to put his/her weight on the transfer device 102. Furthermore, by putting clothes on the transfer device 102, it is possible to make it more anthropomorphic.

[Modification 3]
FIG. 9 is a perspective view illustrating a third modification of the transfer device 2 in the second embodiment.
As illustrated in FIG. 9, the transfer device 200 according to the third modification includes, in addition to the upper body support member 10, the lower body support member 20, the holding arm 30, and the leg body 50, a drive transmission section 400 and a head support member. It further has 70. The upper body support member 10 and the lower body support member 20 are integrally formed by a holding arm 30 and are connected to a drive transmission section 400. Further, the drive transmission section 400 is connected to the leg body 50.

The upper body support member 10 will be explained with reference to FIGS. 9 and 10.
FIG. 10 is a diagram illustrating the configuration of the upper body support member 10 in Modification 3.
The upper body support member 10 illustrated in FIG. 9 is a support member that supports a part of the front side of the upper body of the cared person. Supports the abdomen. The upper body support member 10 is made of an elastic material in the range where the thorax and abdomen and upper limbs of the cared person come into contact. The structure of the upper body support member 10 is substantially the same as that of the first and second embodiments.
Further, as illustrated in FIG. 10, the outer shape of the upper body support member 10 is formed into a substantially trapezoidal shape that is bilaterally symmetrical and has rounded corners. The upper body support member 10 includes upper limb support recesses 17 having round and concave side surfaces in the left and right direction, and is recessed enough to support the arms of the care recipient. Further, the lower side surface of the upper body support member 10 is also rounded and concave.
Further, the support surface of the upper body support member 10 has a central portion that is more concave than a peripheral portion, and is smoothly continuous from the peripheral portion to the central portion.

The width W1 dimension located above the upper body support member 10 is approximately 23 cm or more and approximately 29 cm or less, and the width W2 dimension located below the upper body support member 10 is approximately 36 m or more and approximately 42 cm or less. be. The width W1 of the upper body support member 10 in this example is about 26 cm, and the width W2 is about 39 cm. Further, the height H dimension of the upper body support member 10 is approximately 30 cm or more and approximately 36 cm or less, and the height H dimension of the upper body support member 10 in this example is approximately 33 cm. Further, the thickness T of the upper body support member 10 is formed to be approximately 3 cm or more and approximately 27 cm or less, and the thickness T of the upper body support member 10 in this example is approximately 15 cm. Note that the thickness of the upper body support member 10 can be changed as long as there is no local pressure applied to the upper body of the cared person supported by the upper body support member 10 or the applied pressure does not increase. For example, the pressure distribution applied to the upper body of a cared person supported by the upper body support member 10 with a thickness of about 15 cm, and the pressure distribution applied to the upper body of a cared person supported by the upper body support member 10 with a thickness of about 4 cm. In comparison, the thickness can be made thinner, especially if there is no local pressurization or the pressurization force does not increase.
Further, the size of the support surface of the upper body support part 10 is between twice and seven times the size of the support surface of the lower body support member 20, and the size of the support surface of the upper body support part 10 in this example is larger than the size of the support surface of the lower body support member 20. is four times or more and seven times or less the size of the support surface of the lower body support member 20.

Next, the lower body support member 20 will be explained with reference to FIGS. 9 and 11.
FIG. 11 is a diagram illustrating in detail another configuration of the transfer device 200 in Modification 3.
The lower body support member 20 illustrated in FIG. 9 is located at a lower position than the upper body support part 10 in a state where the cared person is supported, and supports the cared person's lower limbs (specifically, the back of the thigh). The lower body support member 20 is made of an elastic material in the range where the lower limbs come in contact with the lower body support member 20 . The structure of the lower body support member 20 is substantially the same as the upper body support member 10 of the above embodiment.

Further, as illustrated in FIG. 11, the lower body support member 20 has a hemispherical support surface and is formed in a shape having substantially the same aspect ratio, that is, a square shape. Note that the shape of the support surface of the lower body support member 20 is not limited to this, and may be a so-called vertically elongated shape extending in the front and back direction of the cared person supported, or a cared person that is substantially the same as in Example 2 above. It can be changed as appropriate to a so-called horizontally elongated shape that extends in the left and right direction of the person. For example, in order to reduce the contact area with the back of the thighs of the cared person while supporting the cared person, select a lower body support member 20 whose support surface has approximately the same aspect ratio; In addition, in order to increase the contact area with the back of the thighs of the cared person, the lower body support member 20 whose support surface shape is vertically elongated is selected, and the contact area with the back of the thighs of the cared person is selected. If more contact is desired, a lower body support member 20 having a horizontally elongated support surface shape can be selected.
Moreover, the size of the lower body support member 20 is formed to be a size assuming the size of a caregiver's hand. The size of the support surface of the lower body support member 20 is 1/7 to 1/2 times the size of the support surface of the upper body support part 10, and is larger than the support surface of the half body support member 20 of this example. The size is 1/4 or more and 1/7 or less of the size of the support surface of the upper body support part 10. The vertical dimension W and the horizontal dimension D of the lower body support member 20 are approximately 12 cm or more and approximately 18 cm or less, and the vertical dimension W and the horizontal dimension D of the lower body support member 20 in this example are approximately 13 cm.

Next, the holding arm 30 will be explained with reference to FIGS. 9 and 11.
The holding arm 30 illustrated in FIG. 9 is located in front of the supported cared person, and connects the upper body support member 10 and the lower body support member 20. The holding arm 30 can change the distance between the upper body support member 10 and the lower body support member 20.
Further, a protective cover 36 is disposed on the holding arm 30 at a position where the lower limbs of the supported care receiver come into contact with it, specifically, between the holding arm 30 and the lower body support member 20. The protective cover 36 illustrated in FIG. 11 is a flexible synthetic resin sheet material. Thereby, the supported cared person can ride the transfer device 200 without receiving local pressure on the lower limbs due to contact with the holding arm 30.

Next, the configuration of the drive transmission section 400 will be described with reference to FIG. 12.
FIG. 12 is a diagram illustrating the configuration of the drive transmission section 400 in Modification 3 in detail.
As illustrated in FIG. 12, the drive transmission unit 400 tilts the upper body support member 10 and the lower body support member 20 in the front-rear direction of the cared person, and tilts the upper body support member 10 and the lower body support member 20 toward the cared person. This is a device that performs a combined operation of moving the machine in the vertical direction. Note that details will be described later with reference to FIGS. 15 and 16.
The drive transmission unit 400 includes a first support 402 , a second support 404 , a first actuator 410 , a second actuator 412 , and an operating device 430 .
The first support 402 and the second support 404 are columnar hollow members. The leg 50 is connected to one end of the first support 402, and the second support 404 is connected to the other end of the first support 402. At the connection position (first joint portion 440) between the first support column 402 and the leg body 50, the first support column 402 is rotatable.
Further, the first support 402 is connected to one end of the second support 404, and the holding arm 30 is connected to the other end of the second support 404. At the connection position (second joint portion 442) between the second support column 404 and the first support column 402, the second support column 404 is rotatable.

The first actuator 410 and the second actuator 412 move the upper body support member 10 and the lower body support member in the front-rear direction and up-down direction of the cared person by any one of hydraulic, manual, or electric drive methods. 20. The first actuator 410 and the second actuator 412 in this example are electric.
The first actuator 410 is connected to the first column 402 and the leg 50. The first actuator 410 rotates the first column 402 in the front-rear direction about the first joint 440 by reciprocating the piston rod. Further, the second actuator 412 is connected to the first support column 402 and the second support column 404. The second actuator 412 rotates the second support column 404 in the front-rear direction about the second joint portion 442 by reciprocating the piston rod.

The operating device 430 is an operating device that operates the piston rods of the first actuator 410 and the second actuator 412. The operating device 430 performs piston operation on each actuator in a wired or wireless manner. The operating device 430 may operate each actuator individually, or may operate each actuator simultaneously. The operating device 430 of this example operates each actuator individually.

Next, the head support member 70 will be explained with reference to FIG. 13.
FIG. 13 is a diagram illustrating a head support member 70 in Modification 3. FIG. 13(A) is a diagram illustrating the configuration of the head support member 70 in detail, and FIG. 13(B) is a diagram illustrating the position of the head support member 70.
As illustrated in FIG. 13(A), the head support member 70 is a support member that supports the cared person's head in a supported state. The head support member 70 has a base 72 and a cushion 42, and is formed by combining these.
The base 72 is a semicircular base that holds the cushion 42.
The cushion 42 is an elastic member with restoring force, and supports the head of the cared person.
Further, the head support member 70 is fixed to the upper body support member 10 via a left-right position changing section 75.
The left-right position changing unit 75 freely changes the position of the head support member 70 in the left-right direction of the supported cared person. The left-right position changing unit 75 connects two plates (plates A and B) to each other, and makes one plate rotatable. Specifically, the left-right position changing section 75 rotatably connects one end of the plate A and one end of the plate B. Further, in the left-right position changing section 75, the upper body support member 10 is fixed to the other end of the plate A, and the base 72 is rotatably connected to the other end of the plate B. Thereby, the base 72 can rotate around the connection position of the plates B and A (the first connection part 76). Furthermore, the base 72 can rotate around the connection position between the plate B and the base 72 (second connection portion 78).

In this way, the head support member 70 is rotated by the left-right position changing unit 75 illustrated in FIG. 13(A), so that the caregiver can move the head support member 70 as illustrated in FIG. It can be moved left and right. In addition, by rotating the head support member 70 around the second connection portion 78 illustrated in FIG. 13(A), the caregiver can rotate the head support member 70 as illustrated in FIG. can be rotated on the spot.

Next, referring to FIG. 14, it is a diagram illustrating the inclination angle of the upper body support member 10.
FIG. 14 is a diagram illustrating a state in which the upper body support member 10 is tilted in the front-back direction, and FIG. 14 (A) is a diagram illustrating a state in which the upper body support member 10 is tilted in the front direction upon completion of the knee-raising operation. FIG. 14(B) shows a state in which the upper body support member 10 is tilted rearward when the lowering operation is completed. Here, the lifting motion is defined as one person carrying the other person on his or her back, and one person changing from a bent down position to a standing position. This is a lifting motion. In other words, it is an action of lifting the other person on one's shoulders. In this example, the care recipient who is sitting on the bed, chair, etc. that is the transfer source is held by the upper body support member 10, and the cared person who is hugged by the upper body support member 10 is lifted up from the transfer source. .
In addition, the unloading motion is, for example, when one person is carrying the other person, and the other person lowers his or her hips from a standing position, which is the state in which the other person is lifted up. This is the action of putting down the other person. In other words, it is the action of lowering the other person who is being carried up. In this example, this is an action of hugging the upper body support member 10 and lowering the cared person who is being carried onto the transfer destination, such as a bed or chair.
As illustrated in FIG. 14(A), when the knee-raising operation is completed, the drive transmission section 400 tilts the upper body support member 10 forward within a predetermined angle range. The predetermined angle of tilting forward is the angle A between the inclination direction of the support surface of the upper body support member 10 and the vertical direction, and the angle A from the vertical direction is in the range of 45 degrees or more and 65 degrees or less. This is the angle. This allows the cared person to board the vehicle without compromising the cared person's sense of security.
On the other hand, in the driving force transmission unit 400, when the angle between the inclination direction of the support surface of the upper body support member 10 and the vertical direction is 66 degrees or more, the cared person's head tilts forward. This may cause the cared person to feel anxious about falling forward. Furthermore, there is a risk that the care recipient's chest or abdomen may be compressed and the patient may experience pain. Further, in the driving force transmission unit 400, when the angle between the inclination direction of the support surface of the upper body support member 10 and the vertical direction is 44 degrees or less, the cared person leans backward. As a result, the cared person may feel anxious about falling backwards.
Therefore, the driving force transmission unit 400 supports the upper body of the cared person in the front direction so that the angle A between the inclination direction of the support surface of the upper body support member 10 and the vertical direction is in the range of 45 degrees or more and 65 degrees or less. Preferably, the member 10 is tilted. Note that the driving force transmitting unit 400 of this example moves the upper body support member 10 in the front direction of the cared person so that the angle A between the inclination direction of the support surface of the upper body support member 10 and the vertical direction is about 60 degrees. shall be tilted.
Further, as illustrated in FIG. 14(B), when the lowering operation is completed, the drive transmission section 400 tilts the upper body support member 10 backward within a predetermined angle range. The predetermined angle of tilting backward is the angle B between the inclination direction of the support surface of the upper body support member 10 and the vertical direction, and the angle B formed from the vertical direction is in the range of 0 degrees or more and 10 degrees or less. This is the angle. Note that the driving force transmitting unit 400 of this example is arranged so that the angle B between the inclination direction of the support surface of the upper body support member 10 and the vertical direction is approximately 0 degrees or more and 3 degrees or less. It is assumed that the upper body support member 10 is tilted. As a result, the cared person can rest his buttocks on the transfer destination, and therefore can get off the transfer device 200 with a sense of security.

Next, with reference to FIGS. 15 and 16, the operation of the transfer device 200 in Modification 3 will be described. As an example of the operation, a case will be described in which the carer lifts the cared person on his/her back and then lowers him/her down.
(Hunting motion)
FIG. 15 is a diagram illustrating a lifting operation of the transfer device 200 in Modification 3.
As illustrated in FIG. 15(A), first, the caregiver adjusts the position of the upper body support member 10 before transferring the cared person CR. The caregiver extends the piston rod of the first actuator 410 and tilts the first column 402 backward. Thereby, the upper body support member 10 is in a position close to parallel to the vertical direction. After adjusting the position of the upper body support member 10, the caregiver transfers the cared person CR to the transfer device 200.

The caregiver manually carries the transfer device 200 and approaches the cared person CR from the front. The caregiver hugs the cared person CR to the upper body support member 10 and places the lower limbs of the cared person CR on the lower body support member 20. At this time, the cared person CR is placed in a position where the back of the thigh rests on the lower body support member 20.

Next, as illustrated in FIG. 15(B), the caregiver operates the transfer device 200 to lift the cared person sitting on the bed. Here, the transfer device 200 lifts up the cared person who is sitting at a position where the height BH of the bed is about 45 cm.
The caregiver moves the upper body support member 10 and the lower body support member 20 upwardly of the cared person while tilting them in the front direction of the cared person. In other words, the CR of the cared person is increased. Specifically, the caregiver retracts the piston rod of the first actuator 410 and tilts the first column 402 forward. As a result, the cared person is lifted upward while leaning forward.

Next, as illustrated in FIG. 15C, the caregiver operates the operating device 430 to tilt the upper body support member 10 further forward, thereby further lifting the cared person CR (lower weight). Bumping completed). Specifically, the caregiver extends the piston rod of the second actuator 412 and tilts the second column 404 forward. As a result, the cared person is further lifted upward while leaning forward. At this time, the second actuator 412 moves the upper body support member 10 so that the angle A between the inclination direction of the support surface of the upper body support member 10 and the vertical direction is about 60 degrees. Tilt.
The caregiver moves the transfer device 200 to a transfer destination with the cared person placed on the transfer device 200. In this way, the caregiver can transfer the cared person from the bed B to the transfer device 200.

(lowering action)
FIG. 16 is a diagram illustrating a lowering operation of the transfer device 200 in Modification 3.
As illustrated in FIG. 16(A), the caregiver brings the transfer device 200 close to the chair C that is the transfer destination. The caregiver moves the cared person downward while operating the operating device 430 and tilting the upper body support member 10 and the lower body support member 20 toward the rear of the cared person. Specifically, the piston rod of the second actuator 412 is retracted, and the second support column 404 is tilted rearward. As a result, the cared person descends downward while leaning backward.

As illustrated in FIG. 16(B), the caregiver lowers the cared person CR onto the chair C by operating the operating device 430 and tilting the upper body support member 10 further backward. Specifically, the caregiver extends the piston rod of the first actuator 410 and tilts the first column 402 in the rearward direction. Thereby, the cared person can descend downward while leaning backward.

As illustrated in FIG. 16(C), the caregiver operates the operating device 430 to lower the cared person CR onto the chair C, and then tilts the upper body support member 10 further rearward than the vertical direction ( (The defeat is complete). At this time, the first actuator 410 tilts the upper body support member 10 so that the angle B between the vertical direction and the inclination direction of the support surface of the upper body support member 10 is about 0 degrees or more and about 3 degrees. After lowering the cared person onto the chair C, the caregiver lowers the lower limbs of the cared person CR placed on the lower body support member 20 and releases the upper body support member 10 from the hug. Thereafter, the caregiver manually carries the transfer device 200 and moves it to another location. In this way, the caregiver can transfer the cared person from the transfer device 200 to the chair C.
As described above, according to the transfer device 200 of this example, it is possible to lift and lower the cared person on his or her back as if carrying the cared person on his back.

FIG. 17 is a schematic diagram showing the movement locus of the upper body support member 10 illustrated in FIGS. 15 and 16.
As illustrated in FIG. 17, the motion locus of the upper body support member 10 of the transfer device 200 takes approximately the same trajectory for both the knee-lifting motion and the knee-lowering motion. Among these, the following explanation will be given using a specific example of a kneeling motion.
If the order of the upper body support member 10 is 10A to 10H, the position of the upper body support member 10 in the vertical direction is The lowest position is at position 10A when the lifting operation is started, and the highest position is at 10H when the lifting operation is completed.
The locus (10A to 10H) of the upper body support part 10 rotates with respect to the front direction of the cared person as time passes. Furthermore, if each upper body position of the upper body support member 10 (10A to 10H) is assumed to be a point G, and the order of operation is G1 to G8, the locus of the upper position G point of the upper body support member 10 will change as time passes. It is moving upward while moving forward. That is, it means that the upper body support member 10 is moving upward of the cared person while being tilted with respect to the front direction of the cared person as time passes.

As explained above, it is difficult for a caregiver to lift a cared person who is sitting at a position of about 45 cm (bed or chair) on their back (so-called piggyback movement from a low center of gravity position). According to the transfer device 200 in No. 3, it is possible to easily perform a piggyback motion from a low center of gravity position.
Further, according to the transfer device 200, since the cared person is lifted in a piggyback state, the caregiver can easily put on and take off the cared person's lower limb clothes when assisting the cared person to excrete.

[Comparison of simulations in piggyback motion from a low center of gravity position]
The piggyback motion is performed when a human (adult) performs a piggyback motion from a low center of gravity position (hereinafter referred to as pattern A) and when the transfer device 200 performs a piggyback motion from a low center of gravity position (hereinafter referred to as pattern B). Simulations were compared.
(Simulation conditions)
(Pattern A: When a human performs a piggyback motion from a low center of gravity)
Motion capture measurements were conducted using adult men of the same height as the subject on the side of the piggyback and the subject on the side being carried.
(Pattern B: When the transfer device 200 performs a piggyback motion from a low center of gravity position)
Motion capture measurements were performed using an adult male of the same height as the subject on the side used in pattern A as the subject on the side being hit.

(Simulation results)
This will be explained below with reference to FIGS. 18 to 20.
FIG. 18 is a comparison diagram illustrating the movement locus of the center of gravity position in the simulation of lifting up and lowering down.
FIG. 19 is a comparison diagram illustrating the motion locus of the hip joint (greater trochanter) in the simulation of knee-up and knee-down.
FIG. 20 is a comparison diagram showing the locus of movement of the shoulder (acromion) in simulations of raising the shoulders and lowering the shoulders.
As illustrated in FIGS. 18 to 20, from the simulation results of pattern A and pattern B, it was confirmed that the motion trajectories of both patterns were similar. Furthermore, it was confirmed that pattern B drew a smoother curve than pattern A, and that the locus of the lifting motion and the locus of the lowering motion drew approximately the same curve. In other words, it is considered that pattern B was able to reproduce smoother motion because the rapid displacement of the motion locus was controlled.

[Comparison of mental loads received from the upper body support member 10 before and while boarding the transfer device 200]
Load activities that occur in the mind and body of the subject who is being burdened in the case of a resting sitting position before boarding the transfer device 200 (hereinafter referred to as pattern A) and in the case 1 minute after boarding (hereinafter referred to as pattern B) The changes were measured using an autonomic nerve reactor.
(Measurement conditions)
The arterial pressure waveform at the subject's fingertip was measured for 1 to 2 minutes, and the systolic pressure for each beat was converted into a time series waveform, and the slowly fluctuating wave derived from vasomotion (low frequency band LF: 0.04 ?0.15Hz) and rapidly fluctuating waves (high frequency band HF: 0.15 to 0.5Hz) derived from mechanical blood pressure fluctuations caused by breathing, and the ratio of LF/HF was measured.
(Measurement method)
As changes in the autonomic nervous system, the sympathetic nervous system (SNS), parasympathetic nervous system (PSNS), and the SNS/PSNS ratio (ANS activity) were evaluated. The measurement subjects were 2 women and 4 men, 2 times each, for a total of 12 times.

(Experimental result)
This will be explained below with reference to FIGS. 21 and 22.
FIG. 21 is a bar graph showing autonomic nervous system activity, sympathetic nervous system activity, and parasympathetic nervous system activity before and during boarding of the transfer device 200 in Modified Example 3.
FIG. 22 is a bar graph showing pulses before and during boarding of the transfer device 200 in Modification 3.
According to the autonomic nervous system activity (ANS activity) illustrated in FIG. 21(A), pattern A was 7.4±0.5, while pattern B was 6.3±0.8. .
Furthermore, according to the sympathetic nerve activity (SNS Act) illustrated in FIG. 21(B), pattern A is 6.4±0.7, while pattern B is 5.5±1.0. Ta.
Furthermore, according to the parasympathetic nervous system (PSNS) illustrated in Figure 21(C), pattern A was 5.7±0.5, while pattern B was 4.9±0.9. .
According to the change in heart rate (HRV index) illustrated in FIG. 22, pattern A was 11.9±3.1, while pattern B was 8.5±2.5.

(Conclusion)
As a result of measuring the reaction of the autonomic nervous system using the transfer device 200, it was confirmed that autonomic nerve activity, pulse displacement, etc. were lower in pattern B than in pattern A. In other words, it is considered that this does not lead to a significant increase in the load on mental and physical functions during boarding.
