Description

Human body transfer device

The present invention relates to a human body transfer device, and more particularly to a human body transfer device that transfers a person who is difficult to walk.

”Wheelchairs may be used as a means of movement by elderly people or people who have difficulty in walking on their own due to their inflexibility. However, when moving from a wheelchair to a target place such as a bed or a toilet, it is necessary to get on and off the wheelchair, but it is difficult to move on its own and care may be required. In addition to getting on and off the wheelchair, it may require nursing care when moving.

JP 2013-78482 A

Here, when a cared person such as an elderly person is moved to a wheelchair or the like, a lifting-type transfer device that lifts and transfers the cared person may be used. However, when a lifting-type transfer device is used, the lifting device is attached to the cared person, the lifting operation is performed with the device, the cared person is transferred to the target location, and the lifting device is removed from the cared person. The process of removing is taken. For this reason, there has been a problem that it takes time and labor to transfer the care recipient.

For this reason, the caregiver picks up the cared person and transfers it to a desired place such as a wheelchair without using a lifting-type transfer device. However, when the caregiver picks up the cared person and transfers it, the weight of the cared person who picks up the cared person makes the transfer itself difficult, and sometimes the carer hurts the waist.

As a technique for solving the above-described problem, a transfer device disclosed in Patent Document 1 is disclosed. This transfer device is configured to support and lift the upper body and legs of the transferee, that is, the whole body.

However, in the technique of Patent Document 1 described above, since the transporter is only leaning on the upper body, there arises a problem that the transporter slides down. For this reason, it is difficult to use as a transfer apparatus, and the problem that the reliability of an apparatus is low arises. In addition, since the whole body of the transferee is lifted, the transferer cannot be lifted if there is not enough power for the device to be lifted and driven. Is required. Then, there arises a problem that the apparatus configuration becomes large and the cost increases.

Therefore, an object of the present invention is to provide a human body transfer device that can reliably transfer a person to be transferred and can be manufactured at low cost, which is the above-described problem.

In order to achieve the above object, a human body transfer device according to one aspect of the present invention comprises:
A traveling unit equipped with a wheel that touches the ground on the base on which the transferred person puts his feet,
Provided above the traveling unit, and supporting the upper body support part for supporting the upper body of the transferee and the arm part of the transferee while the transferee is leaning on the front side. A human body support portion having an arm support portion;
The human body support part is connected to one end side, and the other end side is pivotally supported at a predetermined position of the apparatus;
A movable part movable so that the support arm rotates about the other end side as a fulcrum,
The arm support unit includes an elbow enclosure that supports and supports the elbow of the transferee,
The movable part rotates the support arm by pushing up the support arm from below, and moves the arm support part and the upper body support part constituting the human body support part in a direction in which the front surface of the transferee faces. And moving the upper body support portion so that its height position is higher,
Take the configuration.

According to the above invention, first, the person to be transferred leans to the human body support part of the human body transfer device on the front side, so that the upper body and arm part of the person to be transferred are supported by the human body support part. . At this time, the chest and / or abdomen, which is the upper body on the front side of the transferee, is leaned against the upper body support part constituting the human body support part, and both arm parts are arm support parts constituting the human body support part And the elbow part is surrounded by the elbow enclosure.

Then, in the movable part, by pushing up the support arm from below and rotating the support arm, the height of the upper body support part is increased, and the arm support part and the upper body support part are directed to the front side of the transferee Moved to move. Then, the to-be-transferred person's torso, especially the waist, is lifted upward by the height of the upper body support portion being increased. At this time, since the arm part of the transferred person is surrounded and firmly supported by the arm support part and the elbow enclosure part, the arm part is moved together with the arm supporting part in a direction in which the front surface of the transferred person faces. That is, the arm portion firmly supported by the arm support portion is pulled in the front direction and the upward direction. For this reason, a transfer person can lift a waist reliably, without falling down from an apparatus.

At this time, the support arm rotated by being pushed up from below by the movable part is connected only to the structure supporting the upper body including the arm part as the structure to support the transferee. The total weight of the transferor is not applied. For this reason, the force for moving the support arm is small, and the apparatus configuration can be simplified and the cost can be reduced.
In this way, the waist of the person to be transferred can be lifted from the state of being seated on the predetermined seat, and the person to be transferred can be easily transferred.

Further, in the human body transfer device, a gripping portion that leans against the upper body support portion and can be gripped by a hand by a person to be transported while the elbow portion is supported by the elbow enclosure portion of the arm support portion is provided. , Provided on the support arm,

[Constitution]
As shown in FIGS. 1 and 3, the human body transfer device first has a footrest 4 (base) on which a cared person 20, who is a person to be transferred, puts his / her foot as a running unit, and four grounding devices. Wheels (two rear wheel casters 17, two front wheel casters 19). In the present embodiment, the wheel (rear wheel caster 17) side located on the left side in FIG. 1 is referred to as “rear”, and the wheel (front wheel caster 19) side located on the right side is referred to as “front”. In addition, as will be described later, the care recipient 20 (transferee) transferred by the human body transfer device of the present invention has his or her “front side”, that is, the chest and abdomen, in the “rear” (leftward direction in FIG. 3). It will be in the state leaning against the said human body transfer apparatus toward the side. For this reason, the “front” direction (the right side direction in FIG. 3) is the direction in which the rear surface of the care receiver 20 faces.

Each of the four wheels, that is, each rear wheel caster 17 and each front wheel caster 19 is provided on one end side which is a tip of each rear wheel arm 5 and each front wheel arm 6, and each of the arms 5 and 6 (leg portions). ) Are each supported. As shown in FIG. 2, the other end side, which is the rear end of each rear wheel arm 5, is pivotally supported by a bottom plate 3 provided on the lower surface side of the footrest 4.

A rear wheel link arm 14 is connected to the other end of each rear wheel arm 5 (the end opposite to the end where the rear wheel casters 17 are provided), and each rear wheel link The arms 14 are connected to each other by a rear wheel link 15. Thereby, each rear-wheel arm 5 which makes a pair is comprised so that between the one ends which are each front end side may open and close by rotating the other end side as a fulcrum, respectively. In other words, the distance between the rear wheel casters 17 is opened or closed by opening or closing each rear wheel arm 5. One rear wheel arm 5 is provided with a rear wheel opening / closing lock 16 that locks the rear wheel arm 5 so as not to rotate.

The configuration of each front wheel arm 6 that supports each front wheel caster 19 is as shown in FIG. 2, and is the same as the configuration of the rear wheel arm 5 described above. That is, the other end side of each front wheel arm 6 (the end opposite to the end provided with the front wheel caster 19) is also pivotally supported by the bottom plate 3 so as to be rotatable. For this reason, each front wheel arm 6 which makes a pair rotates with the other end side as a fulcrum, so that the distance between each front wheel caster 19 provided on one end side is opened or closed. The rear wheel caster 17 is provided with a brake 18 as shown in FIG.

Two frames extending upward are provided at a predetermined position on the front wheel caster 19 side of the footrest 4 constituting the traveling unit. As shown in FIG. 3, the front side such as the shin or knee of the cared person 20 (transferee) that is leaning on the front side with respect to a breast pad 11, which will be described later, is interposed between the two frames. The leg part contacts and is provided with a knee pad 8 (leg pad part) that supports the leg part. The knee pad 8 is fixed to two frames so as not to move, and is not connected to a human body holding arm 10 described later. For this reason, the load on the leg or lower body of the care receiver 2 supported by the knee pad 8 does not apply to the human body holding arm 10.

Further, the two frames provided with the knee pads 8 are bent backward at a predetermined height position, for example, around the waist height position of the cared person 20 sitting on the bed 21. Yes. Further, the two frames are bent further upward near the rear end of the apparatus itself, and a steering handle 7 is formed near the end of each frame. The steering handle 7 is operated when the caregiver runs the human body transfer device.

As shown in FIG. 1, the human body transfer device includes a lower frame 2 that further extends rearward on the rear side, which is the rear wheel caster 17 side of the footrest 4 that constitutes the traveling unit. A support column 1 extending upward is provided at the tip of the lower frame 2. Two human body holding arms 10 (support links) that extend forward and upward, that is, obliquely forward, are provided near the upper end of the column 1. The other end of the human body holding arm 10 is pivotally supported by the human body holding arm rotating shaft 24 with respect to the support column 1. That is, the other end of the human body holding arm 10 is a predetermined location that is separated by a predetermined distance in the front side direction from the position of the cared person 20 in a state of leaning on the front side with respect to a breastplate 11 described later. It is pivotally supported at a location located near the upper end of the column 1.

Further, a breast pad 11 (upper body support part) and an elbow pad 12 (arm support part) are fixedly mounted on the tip of the human body holding arm 10 as a human body support part for supporting the care recipient 20. Specifically, as shown in FIG. 3, the chest pad 11 comes into contact with the chest and / or abdomen (the front side of the upper body) of the cared person 20 in the state of facing the rear, and the chest and / or the abdomen ( In order to support the upper body), it is provided with an inclined surface facing forward and upward, that is, obliquely forward. Thereby, as shown in FIG. 3, the cared person 20 can lean against the breast pad 11 while facing the front side (chest or abdomen side) of the person to the rear side.

In the vicinity of the upper end of the breast pad 11, an elbow pad 12 that is positioned further rearward and on which the arm part (elbow part) of the care receiver 20 is placed and supports the arm part is fixedly equipped. Specifically, the length of the elbow rest 12 is such that the part from the elbow part in the state where the elbow part is bent at the elbow part to the hand of the both sides of the cared person 20 can be placed. Is formed. Furthermore, the elbow rest 12 has wall portions 12a (elbow surrounding portions) that surround the periphery of both ends in the longitudinal direction, and the elbow portion of the care recipient 20 is surrounded by the wall portions 12a. .

The wall portion 12a of the elbow pad 12 surrounds the entire periphery of the elbow pad 12 or the periphery of the elbow part so as to form a space in which the arm portion of the care recipient 20 can be fitted. It may be formed. And the arm part of the cared person 20 can be fixed to the elbow rest 12 by fitting in the space surrounded by the wall part 12a.

As a result, the cared person 20 puts the arm from the elbow to the elbow rest 12 in a state of leaning against the breast rest 11 with its front side facing rearward as shown in FIG. The arm portion can also lean against it. Then, the cared person 20 pushes the elbow rest against the wall portion 12a of the elbow rest 12 with the chest or abdomen leaning against the tilted breast rest 11 or puts the elbow rest on the side. By sandwiching 12, the support of the care recipient 20 is stabilized. As a result, as will be described later, the elbow rest 12 moves so as to pull the arm portion of the cared person 20 in the front side direction, thereby suppressing the body of the cared person 20 from shifting downward downward. be able to. Further, by fitting and fixing the arm portion of the cared person 20 to the elbow pad 12, the support of the arm part of the cared person 20 becomes more stable and the arm part of the cared person 20 can be easily lifted. .

The human body holding arm 10 is connected only to the human body support portion including the chest pad 11 and the elbow pad 12 among the structures for supporting the care recipient 20. That is, the knee pad 8 described above is not connected to the human body holding arm 10. For this reason, the entire weight of the care receiver 20 is not applied to the human body holding arm 10.

Further, as shown in FIG. 3, a human body holding band 23 is provided near the lower end of the breast pad 11 so as to be wound around the waist of the cared person 20 leaning on the breast pad 11. As a result, the upper body and waist of the cared person 20 can be fixed to the breastplate 11.

As shown in FIGS. 1 and 3, the human body holding arm 10 having the human body support portion composed of the breast pad 11 and the elbow pad 12 fixed on one end side is provided between one end side and the other end side of the human body holding arm. In addition, one end of a drive link made up of two link members bent in a substantially square shape is connected. And the other end of the substantially letter-shaped drive link is connected to the vicinity of the lower end of the above-mentioned support column 1. Furthermore, an actuator 9 (movable portion) is provided on the link member on the support column 1 side of the drive link, and the link member is configured to be movable in a telescopic manner. A controller 13 for controlling the operation of the actuator 9 is provided on the rear side of the footrest 4, and a switch 22 for inputting an operation command to the actuator 9 is provided in the vicinity of the steering handle 7 as shown in FIG. ing.

As described above, when one link member of the drive link is expanded and contracted by the actuator 9, the human body holding arm 10 connected to one end of the drive link is subjected to a force that is pushed upward or pulled downward. Will be energized. At this time, since the other end of the human body holding arm 10 is rotatably supported by the human body holding arm rotating shaft 24 located near the upper end of the support column 1, one end of the human body holding arm 10 has the other end as a fulcrum. Rotate at, and move in an arc shape. As the human body holding arm 10 is moved, the human body support portion including the chest pad 11 and the elbow pad 12 provided at one end of the human body holding arm 10 is also moved in an arc shape. With this operation, the breast pad 11 and the elbow pad 12 move along the direction in which the front surface of the care receiver 20 faces, and the breast pad 11 further moves up and down in the height direction.

Specifically, the actuator 9 has a function of moving the human body support part to two positions by moving the human body support part by the breast pad 11 and the elbow pad 12 in an arc shape as described above. First, as shown in FIG. 3 to be described later, the actuator 9 supports the human body on the front side of the cared person 20 in a state where the cared person 20 is seated on a seat of a predetermined height such as a bed 21. The human body support part can be moved to a height position (first position) at which the upper body and the arm part can be supported. That is, the actuator 9 reduces the link member so as to change from the state shown in FIG. 4 to the state shown in FIG. 3 and pulls the human body holding arm 10, so that the chest pad 11 and the elbow pad 12 are While moving in the forward direction, which is the direction in which the back is directed, the human body support unit 10 is rotated in a clockwise direction so that the breastplate 11 portion is moved downward in the height direction.

Further, as shown in FIG. 4 described later, the actuator 9 has a position (second position) in which at least the position in the height direction of the breast pad 11 constituting the human body support portion is higher than the position (first position) shown in FIG. It has a function of moving the human body support part so that That is, the actuator 9 extends the link member and presses the human body holding arm 10 so that the state shown in FIG. 4 is changed to the state shown in FIG. The human body support unit 10 is made to rotate counterclockwise so that the chest pad 11 is moved higher in the height direction while moving in the rearward direction, which is the direction in which the front surface of the human body is directed.

[Operation]
Next, the state at the time of use of the human body transfer apparatus of the structure mentioned above is demonstrated with reference to FIG. 3 thru | or FIG. Here, a case where the cared person 20 is sitting on the bed 21 from the state is moved to a target place such as a wheelchair or a toilet and is further seated in the target place will be described as an example.

First, the front side of the human body transfer device is moved closer to the front side (front side) of the cared person 20 sitting on the bed 21. Then, as shown in FIG. 3, the cared person 20 receives the care of the caregiver, if necessary, puts his / her foot on the footrest 4 of the human body transfer device, and places the shin (knee) on the knee pad 8. On the other hand, the chest and / or the abdomen are applied to the breast pad 11 and lean on the front side. Furthermore, the cared person 20 places the arm part (elbow part) on the elbow pad 12 or fits the arm part into the elbow pad 12 and fixes the arm part. Thereafter, the caregiver wraps the human body holding band 23 around the waist of the cared person 20 and fixes the body of the cared person 20 to the breast pad 11.

In addition, the position of the human body support part which comprises the chest pad 11 and the elbow pad 12 is such that the cared person 20 in a state of sitting on a seat of a predetermined height such as the bed 21 as described above is the human body on the front side. Suppose that it is leaning with respect to a support part, and is previously moved to the height (1st position) which can support the chest part and arm part of the care receiver 20.

Subsequently, in the state of FIG. 3, the caregiver operates the operation switch 22 to move the actuator 9. Then, as shown in FIG. 4, the drive link is extended by the movement of the actuator 9, the human body support arm 20 is pushed up and rotated from below, and the chest pad 11 and the elbow pad 12 (human body support part) are counterclockwise in an arc shape. Rotate around. As a result, the chest pad 11 and the elbow pad 12 move in the direction in which the front surface faces, and the height of the breast pad 11 moves high. For this reason, the upper body of the cared person 20 leaning on the breast pad 11 and the elbow pad 12 rotates about the human body holding arm rotation shaft 24 which is the other end of the human body support arm 20 and the front side faces (rear). And move upward. Then, as shown in FIG. 4, the care receiver 20 is moved upward so that the waist of the cared person 20 moves away from the bed 21.

At this time, in particular, since the elbow of the cared person 20 is surrounded and supported by the wall part 12a of the elbow pad 12 that moves forward, the cared person 20 presses the elbow against the wall part 12a, The arm part is firmly supported (fixed) by sandwiching the elbow rest 12 and fitting. For this reason, the arm part is pulled in the front side direction by the movement of the elbow pad 12 described above, and the waist of the cared person 20 can be lifted more reliably without the cared person 20 sliding down from the apparatus. .

Further, only the human body support portion including the chest pad 11 and the elbow pad 12 is connected to the human body support arm 10 rotated by being pushed up from below by the actuator 9 as a configuration for supporting the care recipient 20. For this reason, the whole body weight of the care receiver 20 is not applied to the human body support arm 10. Therefore, the force of the actuator that moves the human body support arm 10 can be small, and the apparatus configuration can be simplified and the cost can be reduced.

Subsequently, in the state shown in FIG. 4, the caregiver operates the control handle 7 to run the human body transfer device itself and moves to a target position, for example, a wheelchair or a toilet. In particular, the caregiver moves the position of the waist of the cared person 20 so as to be positioned above the seating location at the target position. At this time, for example, when the cared person 20 is seated in a toilet, the front wheel caster 19 may interfere with the toilet seat. In such a case, the distance between the front wheel casters 19 is increased by rotating the front wheel arms 6 as described above. Thereby, a seating location such as a toilet can be positioned between the opened front wheel casters 19, and the waist position of the care recipient 20 can be easily moved to a target position.

Thereafter, the caregiver performs the operation opposite to that described above, that is, operates the operation switch 22 to move the actuator 9 to reduce the drive link, and the chest pad 11 and the elbow pad 12 (human body support part) in an arc shape. Rotate clockwise. Then, the state of FIG. 4 from the state of FIG. 4, that is, the chest pad 11 and the elbow pad 12 move in the rear side direction, and the height of the breast pad 11 moves low.

Furthermore, since the entire weight of the cared person 20 is not applied to the human body support arm 10, the force for moving the human body support arm 10 can be small, and the apparatus configuration can be simplified and the cost can be reduced.

<Embodiment 2>
Next, a human body transfer device according to a second embodiment of the present invention will be described with reference to FIGS. FIG. 5 is a perspective view showing a configuration of the human body transfer device in the present embodiment, and FIGS. 6 to 7 are views showing a state when the transferee is transferred using the human body transfer device.

[Constitution]
As shown in FIG. 5, the human body transfer device first has a footrest 104 (base) on which a cared person 120 as a transferee puts his / her foot and four wheels (2 Two rear wheel casters 117 and two front wheel casters 119). In this embodiment, the wheel (rear wheel caster 117) side located on the left side in FIG. 5 is referred to as “rear”, and the wheel (front wheel caster 119) side located on the right side is referred to as “front”. Further, as will be described later, the cared person 120 (the person to be transferred) transferred by the human body transfer device of the present invention has his / her “front side”, that is, the chest and abdomen in the “rear” (left side direction in FIG. 6). It will be in the state leaning against the said human body transfer apparatus toward the side. For this reason, the “front” direction (the right side direction in FIG. 6) is the direction in which the back side faces the care receiver 120.

Each rear wheel caster 117 is equipped at the rear end of the footrest 104. Further, each front wheel caster 119 is equipped on one end side which is a tip of each front wheel arm 106 provided so as to protrude forward from the footrest 104 (toward the back side of the care receiver 120). The traveling unit in the present embodiment may be configured in the same manner as that described with reference to FIGS. 1 and 2 in the first embodiment.

A handle pipe 107 in which a substantially U-shaped pipe is arranged upside down is provided at a predetermined position near the rear of the traveling unit. Specifically, the handle pipe 107 has both ends of a substantially U-shape fixed to the vicinity of both ends on the rear side of the footrest 104, extends rearward and upward, and the horizontal portion located at the center is upward. Is located. The handle pipe 107 is operated when the caregiver runs the human body transfer device.

Further, at a predetermined position of the footrest 104, a substantially U-shaped pipe is arranged upside down, and two leg pipes 130 extending upward are provided. Each leg pipe 130 is in contact with a leg portion on the front side such as the shin or knee of the care recipient 120 (transferee) as will be described later, and a knee rest 131 (leg rest portion) that supports the leg portion. Is provided. The knee pad 131 is fixed by the footrest 104 and the leg adjuster 132 so as not to move, and is not connected to the human body holding arm 110 described later. For this reason, the load on the legs and lower body of the care receiver 120 supported by the knee pads 131 does not apply to the human body holding arm 110.

Further, the angle of the leg pipe 130 with respect to the footrest 104 can be changed according to the fixed position of the leg adjuster 132. Specifically, one end of the leg pipe 130 is rotatably connected to the footrest 104, and a leg adjuster 132 is connected above the leg pipe 130. Then, by changing the connecting position of the leg adjuster 132 to the leg pipe 130 in the front-rear direction, the leg pipe 130 is rotated, and the position of the knee rest 131 can be changed in the front-rear direction. Thereby, the position of the knee pad 131 can be adjusted according to the height of the cared person 120 or the like. The leg adjuster 132 is fixedly mounted on a controller holder 113a, which will be described later, so that the fixing position can be changed.

The controller holder 113a is fixed to the footrest 104 or a portion extending to the rear side of the front wheel arm 106 fixed to the footrest 104. That is, the controller holder 113a is provided on the rear side of the human body transfer device. And the controller holder 113a accommodates the controller 113 which controls operation | movement of the actuator 109 mentioned later.

Further, a link holder 101 having a predetermined height is fixedly mounted on the upper surface of the controller holder 113a. In the vicinity of the upper end of the link holder 101, a human body holding arm 110 (supporting link) extending forward and upward, that is, obliquely forward is provided. The other end of the human body holding arm 110 is rotatably supported with respect to the link holder 101. In other words, the other end of the human body holding arm 110 is at a predetermined location away from the position of the care receiver 120 in a state of leaning on the front side with respect to a body holder 111 described later by a predetermined distance in the front side direction. It is pivotally supported at a location located near the upper end of a certain link holder 101.

A body holder 111 (upper body support part) and an elbow holder 112 (arm support part) are equipped at the tip of the human body holding arm 110 as a human body support part for supporting the care recipient 120. Specifically, as shown in FIG. 6, the body holder 111 is in contact with the abdomen and / or chest (upper front side of the upper body), which is the front side of the care receiver 120 in the state of facing the rear side. And / or an inclined surface facing forward and upward, that is, obliquely forward, to support the chest (upper body). As a result, the cared person 120 can lean against the body holder 111 with the front side (chest and abdomen) facing rearward as shown in FIG.

The body holder 111 is mounted on the tip of the human body holding arm 110 via the slide pipe 111a. As a result, the body holder 111 can be slid in a direction perpendicular to the longitudinal direction of the human body holding arm 110. However, the slide pipe 111 a is not necessarily provided, and the body holder 111 may be fixedly provided at the tip of the human body holding arm 110.

In the vicinity of the upper end of the body holder 111, an elbow holder 112 is fixedly mounted so as to place the arm part (elbow part) of the cared person 120 and support the arm part, further on the rear side. . Specifically, the elbow holder 112 is formed of a plate-like body having a placement surface having a longitudinal direction in the width direction of the upper half of the cared person 120. The elbow holder 112 has a length in the longitudinal direction so that, for example, a part from the elbow part to the previous hand in a state of being bent at the elbow part among both arm parts of the care recipient 120 can be placed. Is formed. Furthermore, the elbow holder 112 has wall portions 112a (elbow enclosure portions) that surround the periphery of both ends in the longitudinal direction, and the elbow portion of the care receiver 120 is surrounded by the wall portions 112a. .

The wall 112a of the elbow holder 112 surrounds the entire periphery of the elbow holder 112 or the periphery of the elbow portion so as to form a space in which the arm of the care recipient 120 can be fitted. It may be formed. And the arm part of the cared person 120 can be fixed to the elbow holder 112 by fitting in the space surrounded by the wall part 112a.

As a result, as shown in FIG. 6, the cared person 120 puts his elbow on the elbow holder 112 and leans his arm while leaning against the body holder 111 with his front side facing backward. This can be done. Then, the cared person 120 presses the elbow holder against the wall 112a of the elbow holder 112 surrounded by the elbow while the body holder 111 leans against the chest or abdomen, or the elbow holder 112 by the side. The support of the care receiver 120 is stabilized by sandwiching. As a result, the elbow holder 112 moves so as to pull the arm portion of the cared person 120 in the front side direction as will be described later, thereby preventing the body of the cared person 120 from shifting downward downward. be able to. Further, by fitting and fixing the arm part of the cared person 120 to the elbow holder 112, the support of the arm part of the cared person 120 becomes more stable and the arm part of the cared person 120 can be easily lifted. .

In this embodiment, the human body holding arm 110 is further provided with an arm post 140 (gripping portion) made of a rod-shaped member having a predetermined length that protrudes substantially upward. The arm post 140 is near the center in the longitudinal direction of the human body holding arm 110, specifically, from the position of the body holder 111 provided on one end side of the human body holding arm 110, on the other end side of the human body holding arm 110. It is provided at a position separated by a predetermined distance toward the link holder 4 side. As shown in FIG. 6, the arm post 140 is leaned against the body holder 111 and the elbow placed on the elbow holder 112 is supported by the wall 112a as shown in FIG. The person 120 is gripped by hand.

Furthermore, two belt hooks 141 (hanging portions) that protrude in a direction different from the protruding direction of the arm post 140 are formed near the upper end (near the protruding end) of the arm post 140. That is, the belt hook 141 is formed to protrude outward from the outer surface of the arm post 140. Then, as shown in FIG. 6, both end sides of the belt 123 wound around the back side of the cared person 120 in a state of leaning against the body holder 111 are respectively hooked on each belt hook 141. At this time, by adjusting the length so that the belt 123 does not sag and being hooked on the belt hook 141, the cared person 120 comes into close contact with the body holder 111, and the upper body is not separated from the body holder 111. .

In addition, only the structure which supports the upper body among the structures which support the care receiver 120 is connected to the human body holding arm 110 described above. That is, the human body holding arm 110 includes a body holder 111, an elbow holder 112, a wall 112a of the elbow holder 112, an arm post 140 (including the belt hook 141), and the like. Only connected. In other words, the knee support 131 described above is not connected to the human body holding arm 110. For this reason, the whole body weight of the care receiver 120 is not applied to the human body holding arm 110.

As shown in FIG. 5, the human body holding arm 110 equipped with the human body support portion including the body holder 111 and the elbow holder 112 on one end side is provided between one end side and the other end side of the human body holding arm 110 as shown in FIG. One end of a drive link equipped with an actuator 109 (drive unit) is connected. The other end of the drive link is connected to the vicinity of the lower end of the link holder 101 described above. The drive link is configured to be extended and contracted by the actuator 109. A switch 122 for inputting an operation command to the actuator 109 is provided in the body holder 111 as shown in FIG.

As described above, when the drive link is expanded and contracted by the actuator 109, the human body holding arm 110 connected to one end of the drive link is biased by a force that is pushed upward or pulled downward. Become. At this time, since the other end of the human body holding arm 110 is pivotally supported by the link holder 101, one end of the human body holding arm 110 rotates around the other end and moves in an arc shape. Become. As the human body holding arm 110 is moved, the human body support portion including the body holder 111 and the elbow holder 112 provided at one end of the human body holding arm 110 is also moved in an arc shape. By such movement, the body holder 111 and the elbow holder 112 move along the direction in which the front surface of the care receiver 120 faces, and the body holder 111 further moves up and down in the height direction. As the human body holding arm 110 rotates, the arm post 140 provided on the human body holding arm 110 also moves in a direction in which the front surface of the care receiver 120 faces.

Specifically, the actuator 109 has a function of moving the human body support portion to two positions by moving the human body support portion by the body holder 111 and the elbow holder 112 in an arc shape as described above. First, as shown in FIG. 6 described later, the actuator 109 supports the human body on the front side of the cared person 120 while the cared person 120 is seated on a seat of a predetermined height such as the bed 21. The human body support part can be moved to a height position (first position) at which the upper body and the arm part can be supported. That is, the actuator 109 reduces the drive link and pulls the human body holding arm 110, thereby moving the body holder 111, the elbow holder 112, and the arm post 140 toward the care receiver 120 while moving the body holder 111 portion. The human body support arm 110 is rotated clockwise so as to move downward in the height direction.

Further, as shown in FIG. 7 to be described later, the actuator 19 has a position (first position) in which at least the position in the height direction of the body holder 111 constituting the human body support portion is higher than the position (first position) shown in FIG. The second body position has a function of moving the human body support portion. That is, the actuator 109 extends the drive link so as to change from the state shown in FIG. 6 to the state shown in FIG. 7 and presses the human body holding arm 110, so that the body holder 111, elbow holder 112, and arm post 140 are moved. The human body support arm 110 is rotated in a counterclockwise direction so that the body holder 111 is moved higher in the height direction while moving further toward the front side of the care receiver 120.

The body holder 111 in the present embodiment described above may be equipped with the human body holding band 23 that is wound around the back side such as the waist of the care receiver 120 described in the first embodiment with reference to FIG. Good.

[Operation]
Next, the state at the time of use of the human body transfer apparatus of the structure mentioned above is demonstrated with reference to FIG. Here, a case where the cared person 120 moves from the state sitting on the bed 21 to a target place such as a wheelchair or a toilet and then sits at the target place will be described as an example.

First, the human body transfer device is brought closer to the front side (front side) of the cared person 120 sitting on the bed 21 from the front side. Then, the cared person 120 receives the caregiver's care if necessary, puts his / her foot on the footrest 104 of the human body transfer device, and puts the shin (knee) on the knee pad 108 while holding the abdomen on the body holder 111. And / or lean against the front side of the chest. Furthermore, the cared person 120 places the arm part (elbow part) on the elbow holder 112 and grips the arm post 140 by hand. At this time, when the arm post 140 is grasped by one hand, the other arm is placed on the elbow holder 112 and fixed. Alternatively, the arm post 140 may be held with both hands. Thereafter, the caregiver wraps the belt 123 around the back of the cared person 120 and hooks both ends of the belt 123 on the belt hook 141.

Note that the positions of the human body support portions constituting the body holder 111 and the elbow holder 112 can be moved up and down by the slide pipe 111 a at the tip of the human body support arm 110. For this reason, the human body support part is arranged in accordance with the position of the abdomen of the cared person 120 in a state of being seated on the seat part of a predetermined height such as the bed 21 as described above.

Subsequently, in the state of FIG. 6, the cared person 120 or the carer operates the operation switch 122 to move the actuator 109. Then, as shown in FIG. 7, the drive link is extended by the movement of the actuator 109, the human body support arm 120 is pushed up and rotated from below, and the body holder 111, elbow holder 112 (human body support portion), and arm post 140 rotates counterclockwise in an arc. As a result, the body holder 111, the elbow holder 112, and the arm post 140 move toward the front side of the care receiver 120, and the height of the body holder 111 moves high. Therefore, the upper body of the cared person 120 leaning against the body holder 111 and the elbow holder 112 rotates around the link holder 101 which is the other end of the human body support arm 120 as a fulcrum, in the front side direction (backward) and upward. Will move. Then, as shown in FIG. 7, the waist of the cared person 120 is moved upward away from the bed 21.

At this time, since the elbow part of the cared person 120 is surrounded and supported by the wall part 112a of the elbow holder 112 that moves forward, the cared person 120 presses the elbow part against the wall part 112a or is fitted. As a result, the arm is firmly supported (fixed). For this reason, the arm part is pulled in the front side direction by the movement of the elbow holder 112 described above, and the waist of the cared person 120 can be lifted more reliably without the cared person 120 falling off the apparatus. .

In addition, the cared person 120 firmly holds the arm post 140 by hand, so that the arm part is pulled in the front side direction by the forward movement of the arm post 140 as described above. For this reason, the lower part of the cared person 120 can be lifted more reliably without the cared person 120 falling off the apparatus.

Further, a belt 123 is wound around the upper body of the cared person 120, and the belt 123 is hooked on a belt hook 141 formed on the arm post 140. Accordingly, as described above, the arm post 140 moves forward, whereby the upper half of the cared person 120 wound around the belt 123 is pulled in the front side direction. For this reason, the lower part of the cared person 120 can be lifted more reliably without the cared person 120 falling off the apparatus.

Further, only the body holder 111, the elbow holder 112, and the arm post 140, which are configured to support the upper body of the care recipient 120, are connected to the human body support arm 110 rotated by being pushed up from below by the actuator 109. Absent. For this reason, the entire weight of the care receiver 120 is not applied to the human body support arm 110. Therefore, the force of the actuator 109 that moves the human body support arm 110 can be small, and the apparatus configuration can be simplified and the cost can be reduced.

Subsequently, in the state shown in FIG. 7, the caregiver operates the control handle 107 to run the human body transfer device itself and moves to a target position, for example, a wheelchair or a toilet. In particular, the caregiver moves the position of the waist of the care recipient 120 so as to be positioned above the seating location at the target position. Then, the operation opposite to that described above, that is, the operation switch 122 is operated so as to move the actuator 109, the drive link is reduced, and the body holder 111 and the elbow holder 112 (human body support portion) are rotated in an arc shape clockwise. Rotate. Then, from the state of FIG. 7 to the state of FIG. 6, that is, the body holder 111 and the elbow holder 112 move in the rear side direction, and the height of the body holder 111 moves low. Therefore, the upper half of the cared person 120 leaning against the body holder 111 and the elbow holder 112 rotates with the other end of the human body support arm 120 as a fulcrum and moves in the rear side direction and downward. Then, as shown in FIG. 6, the position of the waist of the cared person 120 is lowered, and the cared person 120 can be seated at the target position.

As described above, by using the human body transfer device according to the present invention, the body of the care receiver 120 (transferee), in particular, the position of the waist can be easily moved in the vertical direction. Thereby, the cared person 120 can be easily changed between a state where the cared person 120 is seated on a predetermined seat and a state where the cared person 120 is not seated, and the cared person 120 can be easily and quickly transferred to a target place. Can do. As a result, even a caregiver with weak power does not need to care for the cared person, so that the caregiver can be prevented from hurting his / her waist.

Moreover, since the arm part of the cared person 120 is firmly supported, the transporter can reliably lift his / her waist without sliding off the device. Furthermore, since the entire weight of the cared person 120 is not applied to the human body support arm 110, the force for moving the human body support arm 110 can be small, and the apparatus configuration can be simplified and the cost can be reduced.

As mentioned above, although this invention was demonstrated, this invention is not limited to embodiment mentioned above. Various changes that can be understood by those skilled in the art can be made to the configuration and details of the present invention within the scope of the present invention.
