Description

Transfer device

Technical Field

The present invention relates to a transfer device.

Background

A conventional transfer apparatus is disclosed in japanese patent application laid-open No. 2016-154773. The transfer device includes a base, a support column, a holding member, and an operating mechanism. Four casters are provided on the base. The support column extends upward from the base. The holding member is provided so as to be swingable about a horizontal swing axis center with respect to the support column from an initial position to a transfer position, and holds the care-receiver. The operating mechanism swings the holding member with the manual force of the caregiver.

The holding member has a center member, a right side member, and a left side member. The central member is capable of receiving the chest of the care recipient. The right side member is located on the right side of the care recipient in a horizontal first direction with respect to the center member and extends in a second direction orthogonal to the first direction and away from the center member. The right side member can be placed on the right axilla of the care recipient. The left side member is located on the left side of the care recipient in a first direction with respect to the center member and extends in a second direction. The left side member can be placed on the left axilla of the care recipient.

In the initial position, the central member is in a substantially vertical state; in the transfer position, the center member is in a substantially horizontal state. The right member and the left member are displaceable to the expanded position and the contracted position by moving in a third direction orthogonal to the first direction and the second direction. The distance between the right member and the left member at the contracted position is narrower than the distance between the right member and the left member at the expanded position. The displacement of the right member from the enlarged position to the reduced position is performed by placing the right armpit of the care recipient on the right member. The displacement of the left side member from the expanded position to the contracted position is performed by placing the left axilla of the care recipient on the left side member.

When a care recipient sitting on a bed is transferred to a wheelchair, a toilet, or the like by the transfer device, for example, a care recipient first operates an operation mechanism by a manual force to swing a holding member to an initial position. In this state, the care-receiver places the chest against the central member, the right axilla on the right side member, and the left axilla on the left side member. Thereby, the right member and the left member are respectively displaced from the expanded position to the contracted position by moving in the third direction. Here, in the contracted position, both the right member and the left member are closer to the center member than when the members are in the expanded positions. Thereby, in the contracted position, the interval between the right member and the left member is narrowed. Therefore, in this transfer device, the body is sandwiched between the right side member and the left side member from both armpits in a state where the chest of the care recipient is in contact with the center member. Thus, the care recipient holds the chest, torso, right and left axilla by the central member, the right side member and the left side member, respectively. Then, the caregiver operates the operation mechanism with a manual force to swing the holding member to the transfer position. Thereby, the care receiver is lifted up the buttocks from the bed, and the whole body is moved to the transfer device.

Next, after the caregiver moves the base to a wheelchair, a toilet, or the like, the operating mechanism is operated by the manual force to slowly swing the holding member to the initial position, so that the caregiver falls on the wheelchair, the toilet, or the like. Thereby, the buttocks of the care-receiver are dropped on the wheelchair, the toilet, or the like, and the whole body of the care-receiver is moved from the transfer device to the wheelchair, the toilet, or the like. Thus, the caregiver can perform care such as transferring the care-receiver to another place, and changing the clothes while holding the care-receiver on the holding member.

However, the conventional transfer device described above has the following findings: in the transfer position, the right side member and the left side member sandwich the trunk of the care recipient by a force generated by the self-weight of the care recipient, and the care recipient is restrained.

Particularly, some of the care-recipients suffer from hemiplegia due to cerebral infarction. One of the right and left armpits of these persons can move as intended, but the other cannot, and the other arm is in a state of natural sagging or contracture due to its own weight. In the above-described conventional transfer device, it is difficult to transfer the person.

Disclosure of Invention

Thus, one non-limiting subject matter of this example is: provided is a transfer device which is not restricted by a carereceiver during transfer and can easily transfer even a hemiplegic carereceiver who is difficult to deal with in a conventional product.

The subject is achieved by demonstration of the first technical solution. Further developments of the present teaching are described in the dependent claims.

The transfer device of the present example includes:

a base having casters;

a support column extending upward from the base;

a holding member that is provided so as to be swingable about a horizontal swing axis center with respect to the support column from an initial position to a transfer position, and that holds a care recipient; and

an operating mechanism that swings the holding member with a manual force of a caregiver,

the holding member has: a central member capable of receiving the caregiver's chest; a right member which is positioned on the right side of the care recipient in a horizontal first direction with respect to the center member, extends in a second direction orthogonal to the first direction and away from the center member, and can mount the right axilla of the care recipient; and a left side member which is positioned on the left side of the care recipient in the first direction with respect to the center member and extends in the second direction so as to be capable of placing the left axilla of the care recipient,

in the initial position, the center member is in a substantially vertical state,

in the transfer position, the center member is substantially horizontal,

a right-side mechanism that is provided between the center member and the right-side member, and that is capable of moving the right-side member in parallel in the first direction with respect to the center member by manual force in a state where the right arm is not placed on the right-side member in the initial position, and that is capable of fixing the right-side member in the first direction with respect to the center member in a state where the right arm is placed on the right-side member in the initial position and the transfer position,

a left-side mechanism that is provided between the center member and the left-side member, and that is capable of moving the left-side member in parallel with the center member in the first direction by manual force in a state where the left arm is not placed on the left-side member in the initial position, and that is capable of fixing the left-side member in the first direction with respect to the center member in a state where the left arm is placed on the left-side member in the initial position and the transfer position.

In the transfer device of the present example, the right-side mechanism can move the right-side member in parallel in the first direction with respect to the center member by manual force in a state where the right-side arm is not placed on the right-side member in the initial position. The right side mechanism fixes the right side member in the first direction with respect to the center member in a state where the right side member is placed on the right side member at the initial position and the transfer position. On the other hand, the left-side mechanism can move the left-side member in parallel in the first direction with respect to the center member by manual force in a state where the left arm is not placed on the left-side member in the initial position. The left side mechanism fixes the left side member in the first direction with respect to the center member in a state where the left side arm is placed on the left side member at the initial position and the transfer position.

Therefore, the transfer device can independently fix the right side member and the left side member at any position in the first direction by the force based on the self weight of the care recipient at the transfer position. Therefore, the carereceiver hardly feels bound.

In particular, in the case where the care-receiver is a person who has become hemiplegia due to cerebral infarction, the person himself or herself moves one of the right and left armpits in accordance with his or her own idea, and thereby the position of one of the right and left side members in the first direction is determined, and the caregiver can determine the position of the other of the right and left side members in the first direction in cooperation with the person.

Therefore, according to the transfer device, the care-receiver is not bound at the time of transfer, and even the care-receiver of hemiplegia, which is difficult to deal with in the conventional product, can easily transfer.

In other aspects of the present example, the right member may have: a right body on which the right axilla is placed; and a right side arm extending from the right side body to the center member. The left side member may have: a left main body on which a left axilla is placed; and a left side arm extending from the left side body to the center member. The center member may have a guide portion formed with: a right guide chamber into which the right arm is inserted to guide the right arm in a first direction; and a left guide chamber for guiding the left arm on the first wire by inserting the left arm. The right side mechanism may include: a right engaging portion formed at a tip of an upper surface of the right arm; and a right-side engaged portion that is formed to extend in the first direction on an upper surface of the right guide chamber and is engaged with the right-side engaging portion. And, the left side mechanism may include: a left side engaging part formed at a tip of an upper surface of the left side arm; and a left engaged portion that is formed to extend in the first direction on an upper surface of the left guide chamber and is engaged with the left engaging portion. In this case, the present example can be embodied by a simple structure.

In another aspect of the present invention, it is preferable that a right roller is provided at a tip of a lower surface of the right arm, and the right roller rolls on a lower surface of the right guide chamber when the right engaging portion is not engaged with the right engaged portion. Preferably, a left roller is provided at a tip end of a lower surface of the left arm, and the left roller rolls on a lower surface of the left guide chamber when the left engaging portion and the left engaged portion are not engaged with each other. In this case, the right side member and the left side member can be easily moved in parallel in the first direction in a state where the right armpit is not placed on the right side member or the left armpit is not placed on the left side member, and therefore, the operability of the caregiver is improved.

In another aspect of the present invention, it is preferable that a right side stopper mechanism is provided between the guide portion and the right side arm, the right side stopper mechanism preventing the right side arm from coming off the guide portion. Preferably, a left side stopper mechanism is provided between the guide portion and the left side arm, and the left side stopper mechanism prevents the left side arm from falling off the guide portion. In this case, since the right arm can be prevented from coming off the guide portion or the left arm can be prevented from coming off the guide portion, the operability of the caregiver is improved.

In another aspect of the present example, the right side stopper mechanism may have: a right pin disposed within the guide portion and extending in a second direction; and a right slit formed by extending the right side arm in the first direction and passing the right side pin therethrough. In addition, the left side stopper mechanism may have: a left pin disposed within the guide portion and extending in the second direction; and a left slit formed at the left arm extending in the first direction and passing the left pin therethrough. In this case, the right and left arms can be prevented from falling off the guide portion with a simple configuration.

In another aspect of the present example, the right engaged portion may be a tooth in which a tooth surface of a tooth crest facing the opening side from a tooth root is formed as a right engaged engaging surface. Preferably, when a third direction orthogonal to the first direction and the second direction is assumed and a coordinate formed by the first direction and the third direction is assumed, the right engaged surface intersects with the first direction through an origin at the coordinate, and a tooth top side of the right engaged surface forms a right angle or an acute angle with the first direction. The right engaging portion may be a tooth having a tooth surface of a tooth tip extending from a tooth root to an inner side as a right engaging surface. Preferably, the right engaging and mating surface intersects with an extending direction in which the right side arm extends, passing through an origin point, and a tooth crest side of the right engaging and mating surface forms a right angle or an acute angle with the extending direction. Similarly, the left engaged portion may be a tooth in which a tooth surface of a tooth top facing the opening side from a tooth root is formed as a left engaged engaging surface. Preferably, for the left engaged engaging surface, the left engaged engaging surface intersects with the first direction through an origin in coordinates, and a tooth top side of the left engaged engaging surface makes a right angle or an acute angle with the first direction. The left engaging portion may be a tooth having a tooth surface of a tooth tip extending from a tooth root to an inner side as a left engaging surface. Preferably, the left engaging and mating surface intersects with an extending direction of the left side arm through an origin in the coordinate system, and a tooth crest side of the left engaging and mating surface forms a right angle or an acute angle with the extending direction. In this case, the engagement surfaces abut against each other and overcome the force acting in the direction in which the right and left side arms come off, so that the right and left side arms become less likely to come off.

Other aspects and advantages of the present invention will become apparent from the following description and drawings, the disclosed illustrations, and the concepts of the invention disclosed throughout this specification and drawings.

Hereinafter, embodiments according to the present exemplary embodiment will be described with reference to the drawings.

As shown in fig. 1 to 3, the transfer device of the embodiment includes a base 1, a support column 3, a holding member 5, and an operation mechanism 7. The operating mechanism 7 has a handle 70 and a support mechanism 71. In the following drawings, the longitudinal direction of the support column 3 is defined as the vertical direction of the transfer device. The side on which the handle 70 is disposed is the rear side of the transfer device, and defines the front-rear direction of the transfer device. As shown in fig. 3, the left-right direction of the transfer device is defined based on the case where the transfer device is viewed from the front side. The left-right direction is horizontal with respect to a center member 51 described later, and corresponds to the first direction 90 in this example.

As shown in fig. 1 and 2, the base 1 is formed in a substantially rectangular plate shape. A right rear end 1a, a left rear end 1b, and an inclined portion 1c are formed at the rear end of the base 1. The right rear end portion 1a and the left rear end portion 1b are each formed by bending in a stepwise manner upward of the base 1. A caster 13a is attached to a lower portion of the right rear end portion 1a, and a caster 13b is attached to a lower portion of the left rear end portion 1 b. The inclined portion 1c is located between the right rear end portion 1a and the left rear end portion 1b, and is formed in a downwardly inclined shape. A pair of

support plates

1d and 1e extending upward are fixed to the rear end of the base 1.

On the other hand, the front end of the base 1 is formed flat. The front end edge of the base 1 is formed in a straight line shape. As shown in fig. 3, a mark 1f indicating a position where a care recipient puts both feet on the base 1 is marked on the front end of the base 1, and anti-skid processing (not shown) is performed. Further, at the front end of the base 1, a caster 13c is attached to the lower right, and a caster 13d is attached to the lower left.

The column 3 is composed of a pair of right and left

columns

31 and 32 formed of a long plate material. As shown in fig. 1 and 2, the lower ends of the right and left

support columns

31 and 32 are fixed to the approximate center of the base 1, and the upper ends thereof extend upward of the base 1.

As shown in fig. 3, a right knee holding member 15a is attached to the right strut 31, and a left knee holding member 15b is attached to the left strut 32. The right knee holding member 15a has a cushion formed in a shape curved forward and recessed. The left knee holding member 15b also has a cushion member formed in a shape curved forward and recessed.

Further, a cover 33 for covering a swing plate 56 described later is attached to the upper ends of the right column 31 and the left column 32. The cover 33 projects forward of the right and left side stays 31, 32, and has a right rear end fixed to the upper end of the right side stay 31 and a left rear end fixed to the upper end of the left side stay 32. That is, the right side stay 31 and the left side stay 32 are coupled to each other by the cover 33. As shown in fig. 1 and 2, the right and left side stays 31 and 32 are connected to the

support plates

1d and 1e by a connecting plate 1g extending obliquely downward toward the rear. Thus, the right and left side stays 31 and 32 are supported by the

support plates

1d and 1e via the connecting plate 1 g.

The holding member 5 has a swing plate 56, a connecting rod 55, a center member 51, a right side member 52, and a left side member 53.

The swing plate 56 is inserted between the right and left

support columns

31 and 32, and has a base end swingably coupled to the right and left

support columns

31 and 32 by a swing pin 61. The swing pin 61 extends in a horizontal direction, that is, a first direction 90, with respect to the right and left side stays 31 and 32. Thus, the swing plate 56 can swing about the swing pin 61, i.e., about the swing axial center O1 horizontal to the right and left

support columns

31 and 32. The proximal end of the connecting rod 55 is fixed to the distal end of the swing plate 56.

The center member 51 has a center base 51a and a cushion member 51b fixed to the front surface at the initial position of the center base 51 a. The tip of the connecting rod 55 is fixed to the rear surface of the center base 51 a. The cushion member 51b can receive the chest of the care recipient not shown by the surface thereof being in contact with the chest.

The center member 51 has a guide portion 51c between the center base 51a and the cushion 51 b. As shown in fig. 4 to 6, the guide portion 51c is formed with a right guide chamber 42 and a left guide chamber 43, the right guide chamber 42 being a quadrangular prism-shaped space extending horizontally and having a right end opened through the opening 42d, and the left guide chamber 43 being a quadrangular prism-shaped space extending horizontally and having a left end opened through the opening 43 d. Between the right guide chamber 42 and the left guide chamber 43 there is a horizontally extending wall 44.

As shown in fig. 7 and 9 to 11, the right guide chamber 42 has teeth 42a formed in the left half of the upper surface, and the other surfaces are flat surfaces. The teeth 42a are right-side engaged portions. As shown in fig. 8, the teeth 42a are connected by an inclined surface 81 inclined with respect to the first direction 90 between the tooth tip a located at the rear of the right guide chamber 42, that is, on the left side and the tooth root B located on the opening 42d side of the tooth tip a, and connected by the right engaged surface 82 between the tooth tip C located on the opening 42d side of the tooth tip a and the tooth root B. Assuming a third direction 92 orthogonal to the first direction 90 and the second direction (thickness direction of the paper surface) and assuming coordinates formed by the first direction 90 and the third direction 92, the right engaged surface 82 intersects with the first direction 90 through the origin O at the coordinates, and the tooth crest C side of the right engaged surface 82 is perpendicular to the first direction 90.

At a slightly right portion of the right guide chamber 42, a right pin 42b extending at right angles from the center base 51a, that is, in the second direction is fixed.

The left guide chamber 43 is a mirror image of the right guide chamber 42. Therefore, in fig. 7 to 11, the teeth 43a and the left pin 43b of the left guide chamber 43 are illustrated by the teeth 42a and the right pin 42b of the right guide chamber 42. The left guide chamber 43 is formed with teeth 43a in the right half of the upper surface, and the other surface becomes a flat surface. The teeth 43a are left-side engaged portions. A left pin 43b extending at right angles from the center base 51a, that is, in the second direction is fixed to a slightly left portion of the left guide chamber 43.

As shown in fig. 4 to 6, the right side member 52 includes a right side base 52a and a cushion member 52b fixed to a left surface of the right side base 52 a. A right side arm 52c is fixed to the right base 52 a. The right side arm 52c includes: a quadrangular prism-shaped rear extension 52d extending rearward from the right base 52a at an initial position; and a quadrangular prism-shaped horizontal extension portion 52e that is bent at a right angle to the left direction from the rear extension portion 52d and extends in the left direction. The horizontal extension portion 52e is inserted into the right guide chamber 42 of the guide portion 51 c. The horizontal extension portion 52e has a slightly large gap in the vertical direction in the right guide chamber 42 at the initial position, but only a gap in the horizontal extension portion 52e is allowed to move in the front and rear directions.

As shown in fig. 7 and 9 to 11, teeth 52f are formed at the tip of the upper surface of the horizontal extension portion 52 e. As shown in fig. 8, the teeth 52F are connected by the inclined surface 83 inclined with respect to the first direction 90 between the tooth tip D located on the right side of the rear extension portion 52D of the horizontal extension portion 52E and the tooth root E located inside the tooth tip D, and are connected by the right engaging surface 84 between the tooth tip F located inside the tooth tip D and the tooth root E. The right engaging surface 84 intersects with the extending direction of the horizontal extending portion 52e of the right arm 52c through the origin O in the coordinate system, and the tooth tip F side of the right engaging surface 84 is perpendicular to the extending direction. The inclined surface 81 and the inclined surface 83 have the same length, and the right engaged surface 82 and the right engaging surface 84 have the same length. Note that, if the horizontal extension portion 52e is parallel to the first direction 90, the extending direction coincides with the first direction 90. The inclined surface 83 of the tooth 52f is parallel to the inclined surface 81 of the tooth 42a if the extending direction coincides with the first direction 90. The teeth 52f are right engaging portions that engage with the teeth 42a of the right guide chamber 42. The

teeth

52f and 42a correspond to a right mechanism.

Further, a right roller 52g is provided at the tip of the lower surface of the horizontal extension portion 52 e. The right roller 52g is rotatable about a rotation shaft extending in the second direction, and rolls on the lower surface of the right guide chamber 42 when the teeth 52f are not engaged with the teeth 42 a.

Further, a right slit 52h extending in the first direction 90 is formed in the horizontal extension portion 52 e. The right slit 52h is penetrated by the right pin 42 b. The right pin 42b and the right slit 52h correspond to a right stopper mechanism.

As shown in fig. 4 to 6, the left side member 53 includes a left side base 53a and a cushion member 53b fixed to a right surface of the left side base 53 a. A left arm 53c is fixed to the left base 53 a. The left side arm 53c includes: a quadrangular prism-shaped rear extension 53d extending rearward from the left base 53a at an initial position; and a quadrangular prism-shaped horizontal extension portion 53e bent at a right angle from the rear extension portion 53d to the right and extending in the right direction. The horizontal extension portion 53e is inserted into the left guide chamber 43 of the guide portion 51 c. The horizontal extension portion 53e has a slight gap in the vertical direction in the initial position in the left guide chamber 43, but only a gap in the horizontal extension portion 53e is present in the front and rear directions to the extent that the gap can move.

The horizontal extension 53e is a mirror image of the horizontal extension 52 e. Therefore, in fig. 7 to 11, the teeth 53f, the left rollers 53g, and the left slits 53h of the horizontal extension portion 53e are illustrated with the teeth 52f, the right rollers 52g, and the right slits 52h of the horizontal extension portion 52 e. A tooth 53f is formed at the tip of the upper surface of the horizontal extension portion 53 e. The teeth 53f are left engaging portions that engage with the teeth 43a of the left guide chamber 43. The

teeth

53f and 43a correspond to a left mechanism.

Further, a left roller 53g is provided at the tip of the lower surface of the horizontal extension portion 53 e. The left roller 53g is rotatable about a rotation shaft extending in the second direction, and rolls on the lower surface of the left guide chamber 43 when the teeth 53f are not engaged with the teeth 43 a.

Further, a left slit 53h extending in the first direction 90 is formed in the horizontal extension portion 53 e. The left slit 53h allows the left pin 43b to pass through. The left pin 43b and the left slit 53h correspond to a left side stopper mechanism.

As shown in fig. 1 to 3, the handle 70 includes a first handle lever 70a and a second handle lever 70 b. As shown in fig. 3, the first handle lever 70a is formed in a substantially Y-shape with the upper end side branched to the left and right. A first grip 701 is provided at the right upper end of the first lever 70a, and a second grip 702 is provided at the left upper end of the first lever 70 a. Further, a third handle and a fourth handle (only the third handle 703 is shown) are provided on the left and right sides of the lower end of the first lever 70a, respectively.

As shown in fig. 1 and 2, the rear end of the second handle bar 70b is connected to the lower end of the first handle bar 70a at a predetermined angle, and the front end of the second handle bar 70b is connected to the connecting rod 55 at a predetermined angle. Thereby, the holding member 5 is connected to the handle 70. A fifth handle and a sixth handle (only the fifth handle 705 is shown) are provided on the right and left sides of the second handle bar 70b, respectively.

The support mechanism 71 includes the

support plates

1d and 1e and the damper 11. The damper 11 includes a damper main body 11a that is extendable and retractable in the axial direction, an end cap 11b fixed to a lower end of the damper main body 11a, and an operating pedal 9. The damper 11 is connected to the base end of the swing plate 56 via the upper end of the damper main body 11a, and is connected to the swing plate 56 so as to be able to swing. The damper 11 is coupled to the

support plates

1d and 1e via an end cover 11 b.

As shown in fig. 1, when the caregiver steps on the operating pedal 9, the damper 11 is contracted in the axial direction when the holding member 5 swings from the transfer position to the initial position, while as shown in fig. 2, the damper 11 is expanded in the axial direction when the holding member 5 swings from the initial position to the transfer position. The damper 11 adjusts the hydraulic pressure inside to generate a certain resistance when expanding and contracting. When the holding member 5 swings between the initial position and the transfer position, the caregiver releases the foot from the operating pedal 9, and the damper 11 can fix the holding member 5 at an arbitrary swing angle.

The operation of the transfer device configured as described above will be specifically described with reference to a case where a care recipient sitting on a bed, not shown, transfers to a wheelchair, a toilet, or the like as an example. The care-receiver includes elderly persons, injured persons, and the like as well as handicapped persons.

First, the caregiver steps on the operating pedal 9 with his foot. Thereby, the damper body 11a of the damper 11 can expand and contract in the axial direction, and the holding member 5 can swing. In this state, as shown in fig. 1, the caregiver pushes the handle 70 upward to swing the holding member 5 to the initial position. In the initial position, the central member 51 is in a substantially vertical state.

In this state, the care recipient does not yet place the right armpit on the right side member 52, and therefore the weight W of the care recipient does not act on the right side arm 52 c. Therefore, as shown in fig. 7, the teeth 52f of the right member 52 are not engaged with the teeth 42a, and the right roller 52g abuts against the lower surface of the right guide chamber 42. Therefore, the right side member 52 is free to move in parallel in the first direction 90 with respect to the center member 51. Therefore, the caregiver first pulls the right arm 52c in a direction to pull it out of the right guide chamber 42, and the right member 52 is moved away from the center member 51 to the expanded position. At this time, the right roller 52g rolls on the lower surface of the right guide chamber 42, and therefore the right member 52 can be easily positioned at the enlarged position. In the horizontal extension portion 52e, the right pin 42b abuts the left end of the right slit 52h, and the right arm 52c is prevented from coming off the guide portion 51 c.

Since the left armpit of the care recipient is not yet placed on the left side member 53, the weight W of the care recipient does not act on the left side arm 53 c. Therefore, the teeth 53f of the left member 53 do not engage with the teeth 43a, and the left roller 53g abuts against the lower surface of the left guide chamber 43. Therefore, the left side member 53 is also free to move in parallel in the first direction 90 with respect to the center member 51. The caregiver pulls the left arm 53c in the direction of pulling out from the left guide chamber 43, and the left member 53 is moved away from the center member 51 to the expanded position. At this time, the left roller 53g rolls on the lower surface of the left guide chamber 43, and therefore the left member 53 can be easily set to the expanded position. In the horizontal extension portion 53e, the left pin 43b abuts on the right end of the left slit 53h, and the left arm 53c is prevented from coming off the guide portion 51 c.

Thus, as shown in fig. 4, the right side member 52 and the left side member 53 are set at the enlarged positions, and the caregiver moves the transfer device by the casters 13a to 13d with his feet off the operating pedal 9, so that the surface of the center member 51 faces the care recipient. The care recipient places both feet on the mark 1f of the base 1 and causes the right knee holding member 15a and the left knee holding member 15b to hold the right knee and the left knee, respectively. Then, the care recipient abuts the chest against the surface of the center member 51.

The caregiver moves the right side member 52 in parallel to the center member 51 in the first direction 90 by the manual force, and abuts the cushion member 52b against the right side surface of the torso of the caregiver with a moderate strength as shown in fig. 8. In some cases, the caregiver moving the right arm may move the right side member 52 in parallel to the center member 51 in the first direction 90 by himself or herself, and may abut the cushion member 52b against the right side surface of his/her torso with a moderate strength. At this time, the right roller 52g rolls on the lower surface of the right guide chamber 42, and therefore the right member 52 can be easily set to an arbitrary contracted position.

Then, if the care-receiver places the right underarm on the right side member 52, the weight W of the care-receiver acts on the right side arm 52c, and the teeth 52f of the right side member 52 engage with the teeth 42a, as shown in fig. 9. Thus, the right side member 52 is fixed relative to the center member 51 in the first direction 90. More specifically, the right engaging surface 84 of the tooth 52f at the distal end portion of the horizontal extension portion 52e of the right member 52 abuts against the right engaged surface 82 of the tooth 42a of the right guide chamber 42, and the inclined surface 83 of the tooth 52f abuts against the inclined surface 81 of the tooth 42a of the right guide chamber 42. At this time, the right engaging surface 84 abuts against the right engaged surface 82, and the right arm 52c is less likely to come off against the force acting in the direction in which the right arm 52c comes off from the right engaged surface 82 and the right engaging surface 84. The left side arm 53c is also the same.

When the care-receiver is obese and can place only the right underarm on the right member 52 by unfolding, the right member 52 is brought to an arbitrarily contracted position from the center member 51 and the teeth 52f are engaged with the teeth 42a as shown in fig. 11. At this time, the right engaging surface 84 abuts against the right engaged surface 82, and the right arm 52c is less likely to come off against the force acting in the direction in which the right arm 52c comes off from the right engaged surface 82 and the right engaging surface 84. The left side arm 53c is also the same.

On the other hand, the caregiver moves the left side member 53 in parallel to the center member 51 in the first direction 90 by the manual force, and abuts the cushion member 53b against the left side surface of the torso of the caregiver with a moderate strength. The caregiver, who moves the left arm, may move the left side member 53 in parallel to the center member 51 in the first direction 90 by himself or herself, and may abut the cushion member 53b against the left side surface of his/her torso with a moderate strength. At this time, the left roller 53g rolls on the lower surface of the left guide chamber 43, and therefore the left member 53 can be easily set to an arbitrary contracted position.

When the care recipient places the left armpit on the left side member 53, the weight W of the care recipient acts on the left side arm 53c, and the teeth 53f of the left side member 53 engage with the teeth 43 a. Thus, the left side member 53 is fixed in the first direction 90 relative to the center member 51. At this time, the left engaging and engaging surface 84 abuts against the left engaged and engaging surface 82, and the left arm 53c is prevented from coming off by the left engaging and engaging surface 84 abutting against the left engaged and engaging surface 82 against the force acting in the direction in which the left arm 53c comes off. The right side arm 52c is also the same.

When the care-receiver is obese and can place only the left armpit on the left side member 53 while unfolding, the left side member 53 is brought to an arbitrarily contracted position from the center member 51, and the teeth 53f are engaged with the teeth 43 a. At this time, the left engaging and engaging surface 84 abuts against the left engaged and engaging surface 82, and the left arm 53c is prevented from coming off by the left engaging and engaging surface 84 abutting against the left engaged and engaging surface 82 against the force acting in the direction in which the left arm 53c comes off. The right side arm 52c is also the same.

Thus, the holding member 5 is in the state shown in fig. 5 or 6. Thus, the care recipient holds the chest, torso, right and left armpits by the center member 51, the right side member 52 and the left side member 53, respectively.

In this state, the caregiver presses the operating pedal 9 again to swing the holding member 5, and pushes down the handle 70 to swing the holding member 5 from the initial position shown in fig. 1 to the transfer position shown in fig. 2. At this time, the center member 51 is in a substantially horizontal state, but the weight W of the care recipient remains on the hip portion side, and therefore the weight W acts on the right side member 52 and the left side member 53. In the transfer position, the center member 51 may be positioned slightly below the hip portion side. Thereby, the care receiver is lifted up the buttocks from the bed, and the whole body is moved to the transfer device. After swinging the holding member 5 to the transfer position, the caregiver disengages the foot from the operating pedal 9, thereby fixing the holding member 5 at the transfer position. Meanwhile, the transfer device fixes the right side member 52 and the left side member 53 at arbitrary positions in the first direction 90 independently of each other by a force based on the self weight of the care receiver, and thus the care receiver hardly feels bound.

Particularly, in the case where the care-receiver is a person who has become hemiplegia due to cerebral infarction, the person can determine the position of the first direction 90 of one of the right side member 52 and the left side member 53 by himself/herself by moving one of the right arm and the left arm, which is a healthy side, according to his/her own idea, and the caregiver can determine the position of the first direction 90 of the other of the right side member 52 and the left side member 53 in cooperation with the person on the other affected side.

In a state where the care-receiver is placed on the transfer device, the transfer device is moved to the vicinity of a wheelchair, a toilet, or the like, and the care-receiver faces the front end side of the base 1 toward the wheelchair, the toilet, or the like, so that the care-receiver falls on the wheelchair, the toilet, or the like. Thereafter, the caregiver swings the holding member 5 from the transfer position to the initial position by operating the handle 70 and the operating pedal 9. At this time, the caregiver grips the first through sixth handles 701 through 706 again as needed and pushes the handle 70 upward. When the holding member 5 is swung from the transfer position to the initial position, the damper main body 11a expands and contracts in the axial direction while generating a certain resistance. Thus, the care-receiver drops the buttocks on the wheelchair, the toilet, or the like, and the whole body is moved from the transfer device to the wheelchair, the toilet, or the like. In this way, the transfer of the care-receiver from the bed to the wheelchair, the toilet, or the like by the transfer device is completed.

Therefore, according to the transfer device, the care-receiver is not bound at the time of transfer, and even the care-receiver of hemiplegia which is difficult to deal with in the conventional product can easily transfer.

The present invention has been described above with reference to the embodiments, but it is needless to say that the present invention is not limited to the above embodiments, and can be applied with appropriate modifications within a range not departing from the gist thereof.

For example, the right guide chamber 42 and the left guide chamber 43 of the guide portion 51c may be formed integrally without being partitioned by the wall 44. In this case, the right guide chamber 42 and the left guide chamber 43 do not necessarily overlap each other in the front-rear direction in the first direction, and if the width of the center member 51 in the left-right direction is relatively large, a single space extending in the left-right direction may be formed in the center member 51, and 1/2 of the space may be set as the right guide chamber 42 and the left guide chamber 43, respectively.

As shown in fig. 12, the tooth tips C of the right and left engaged

surfaces

82, 82 and the tooth tips F of the right and left engaging

surfaces

84, 84 may form an acute angle θ with the first direction 90. In this case, the right arm 52c and the left arm 53c are less likely to fall off.

Further, the length of the connecting rod 55 may be adjusted so that the distance between the swing plate 56 and the center member 51 can be changed according to the physique of the care recipient. Similarly, the right knee holding member 15a and the left knee holding member 15b may be configured to be movable back and forth according to the physical constitution of the care recipient.

The operating mechanism 7, the

right mechanisms

52f and 42a, the

left mechanisms

53f and 43a, the right engaging portion 52f, the right engaged portion 42a, the left engaging portion 53f, the left engaged portion 43a, the

right stopper mechanisms

42b and 52h, the

left stopper mechanisms

43b and 53h, and the like are not limited to the above-described configurations, and may be designed appropriately.

Further, a spring as an urging member may be provided between the lower surface of the tip end of the horizontal extension portion 52e and the lower surface of the right guide chamber 42 so that the teeth 52f and the teeth 42a are reliably engaged with each other in the transfer state; a spring as an urging member may be provided between the top end upper surface of the horizontal extension portion 52e and the upper surface of the right guide chamber 42 so that the engagement of the teeth 52f and the teeth 42a is released in the initial state. The urging members may be a permanent magnet and a magnetic body that attract each other or a permanent magnet and a permanent magnet that repel each other.
