Description

The present invention relates to a technique of a transfer support device provided with a holding mechanism for supporting the back of a care recipient by abutting the back of the care recipient from behind.

Conventionally, a technique of a transfer support device provided with a holding mechanism for supporting the back of a person to be cared by contacting the back of the care recipient from behind has been known. For example, as described in Patent Document 1.

As shown in FIG. 11, the holding mechanism according to Patent Document 1 is composed of a pair of left and right tilting shafts 91, a pair of left and right second holding portions 92, and a connecting belt 93. The tilt axis 91 is arranged so that its axial direction is substantially in the vertical direction (direction of the back muscle of the care recipient P). The second holding portion 92 is rotatably connected to the tilting shaft 91, and is pressed against the back of the care recipient P by rotating around the tilting shaft 91. The connecting belt 93 is connected to a pair of left and right second holding portions 92. With the connecting belt 93, the holding mechanism suppresses the second holding portion 92 from rotating backward when the care recipient P puts his / her weight on the second holding portion 92.

However, the second holding portion 92 described in Patent Document 1 has a substantially vertical direction as the rotation axis direction. In such a configuration, the rearward load F generated when the care recipient P puts his / her weight acts in the tangential direction of the rotation locus L9. Therefore, the rearward load F causes the second holding portion 92. A large torque is applied to. In this case, the connecting belt 93 is subject to a large load to regulate the rotation of the second holding portion 92.

Hereinafter, the transfer support device 1 according to the present embodiment will be described with reference to FIGS. 1 to 4.

The transfer support device 1 shown in FIG. 1 carries a care recipient P (a person receiving care) and moves to transfer the care recipient P (for example, transfer between a bed and a toilet, transfer between a bed and a wheelchair). It supports transfer, transfer to the transfer support device 1 itself, etc.). The transfer support device 1 mainly includes a carriage portion 2, a support portion 3, and an upper body holding portion 10.

The dolly unit 2 can move on the ground (floor surface). A support portion 3 is provided on the upper portion of the carriage portion 2.

The support portion 3 is oscillatingly connected to the carriage portion 2 back and forth by expansion and contraction of a cylinder (not shown) provided between the support portion 3 and the carriage portion 2. At the rear of the support portion 3, a seating portion 3a on which the care recipient P boarding the transfer support device 1 can be seated is provided. The front portion of the support portion 3 is provided with a knee receiving portion 3b for receiving the knee of the care recipient P and a handle portion 3c for the care recipient P to grasp.

The upper body holding portion 10 is a portion that holds the body (upper body) of the care recipient P. As shown in FIGS. 1 and 2, the upper body holding portion 10 mainly includes a front holding portion 11, a side holding portion 12, and a back holding mechanism 20.

The front holding portion 11 is a portion that holds a portion extending from the chest to the abdomen of the care recipient P. The front holding portion 11 is formed in a substantially rectangular parallelepiped shape, and holds the upper body of the care recipient P from the chest side on the rear surface. The rear surface is arranged so as to face rearward and upward.

The side surface holding portion 12 is a portion that holds the care recipient P from both the left and right sides of the armpit. The side surface holding portion 12 is formed in a substantially rectangular parallelepiped shape extending rearward and upward from the front holding portion 11. A pair of left and right side holding portions 12 are provided so as to sandwich the front holding portion 11 in the left-right direction.

The back holding mechanism 20 is for supporting the back of the care recipient P. The back surface holding mechanism 20 is connected to the pair of left and right side holding portions 12, respectively, and is provided in pairs on the left and right. As shown in FIGS. 2 and 3, the back surface holding mechanism 20 includes a contact portion 30, a rotating shaft 40, and a regulating mechanism 50. In the following, the back surface holding mechanism 20 on the left side will be described, and the description of the back surface holding mechanism 20 on the right side will be omitted. Further, in the following, the left back holding mechanism 20 is in a state where the contact portion 30 as shown in FIG. 2 is in contact with the back of the care recipient P (hereinafter, referred to as “contact state”). To do.

The contact portion 30 is a portion that contacts the back of the care recipient P from behind. The contact portion 30 is arranged behind the side surface holding portion 12. The contact portion 30 includes a base 31 and a cushion 32.

The base 31 is the rear portion of the contact portion 30, and is formed in a substantially rectangular parallelepiped shape. The base 31 is formed so as to extend from the rear end portion of the side surface holding portion 12 to the back of the care recipient P (forward to the right) in the contact state. The base 31 is made of a hard material such as resin.

The cushion 32 is for reducing the load applied to the care recipient P when supporting the back, and is made of a soft material such as urethane. The cushion 32 is attached to the front surface of the base 31.

The rotation shaft 40 is for rotatably supporting the contact portion 30. The rotation shaft 40 is formed so as to extend to the left front from the contact portion 30, and is rotatably supported by the side surface holding portion 12. Further, the rotating shaft 40 is configured to be movable relative to the side surface holding portion 12 in the axial direction (left front and right rear). The left rear portion of the contact portion 30 is fixed to such a rotating shaft 40. As a result, the rotating shaft 40 supports the contact portion 30 so as to be rotatable and movable in the axial direction of the rotating shaft 40.

In the following, the portion of the contact portion 30 that is separated from the rotation shaft 40 (the front right portion in FIG. 2) is referred to as the “tip portion 30a”.

The regulation mechanism 50 is for restricting the rotation of the contact portion 30 in a predetermined case. As shown in FIG. 4, the regulation mechanism 50 includes a case 51, an interlocking plate 52, a movable brake portion 53, a fixed brake portion 54, and a spring 55.

The case 51 is a substantially box-shaped member. The case 51 is fixed in the side surface holding portion 12 (see FIG. 2). A rotation shaft 40 is inserted through the case 51. Such a case 51 is configured so as not to rotate with the rotation of the rotation shaft 40 (contact portion 30). Further, the case 51 is configured so as not to move with the movement of the rotation shaft 40 (contact portion 30) in the axial direction.

The interlocking plate 52 is a substantially plate-shaped member. The interlocking plate 52 is provided in the case 51. The interlocking plate 52 is fixed to the rotating shaft 40 and is arranged with a gap with respect to the inner side surface of the case 51. Such an interlocking plate 52 rotates integrally with the rotation of the rotating shaft 40, and also moves integrally with the movement of the rotating shaft 40 in the axial direction.

The movable brake portion 53 is a substantially annular member. The movable brake portion 53 is fixed to the rear surface of the interlocking plate 52, and is arranged with a gap between the inner surface surface of the case 51 and the rotation shaft 40. The movable brake portion 53 is made of a material having a higher friction coefficient than the interlocking plate 52. Similar to the interlocking plate 52, such a movable brake unit 53 operates integrally with the operation (rotation and movement) of the rotation shaft 40.

The fixed brake portion 54 is a member formed in substantially the same shape as the movable brake portion 53. The fixed brake portion 54 is made of a material having a higher coefficient of friction than the case 51. The fixed brake portion 54 according to the present embodiment is made of the same material as the movable brake portion 53. The fixed brake portion 54 is fixed to the inner surface (right rear portion) of the case 51 and is arranged to the right rear of the movable brake portion 53. The fixed brake portion 54 faces the movable brake portion 53. Like the case 51, such a fixed brake portion 54 is configured so as not to operate with the operation (rotation and movement) of the rotation shaft 40.

The spring 55 urges the interlocking plate 52 and the movable brake portion 53 toward the left front (direction away from the fixed brake portion 54). The spring 55 is provided inside the case 51, and one end thereof abuts on the rear surface of the interlocking plate 52 and the other end abuts on the inner surface of the case 51.

Next, the operation of supporting the back by the back holding mechanism 20 will be described with reference to FIGS. 2, 5 to 9. As shown in FIG. 5, it is assumed that the upper body of the care recipient P is held by the front holding portion 11 and the side holding portion 12 in the state before the operation. Further, it is assumed that the tip portion 30a of the contact portion 30 faces upward in the state before the operation. The tip portion 30a is located on the left rear side of the back of the care recipient P.

First, the contact portion 30 is rotated so that the tip portion 30a is directed toward the left and right inside (right side). At this time, the contact portion 30 rotates about the rotation shaft 40, and the left-right position of the tip portion 30a is adjusted so that the tip portion 30a is located behind the back of the care recipient P.

The rotation shaft 40 is formed so as to extend in a direction extending outward to the left and right with respect to the front (see the virtual line L shown in FIG. 5). For this reason, the tip portion 30a of the contact portion 30 is pushed forward (moves to the right front) by rotating inward to the left and right. As a result, as shown in FIG. 2, the tip portion 30a of the contact portion 30 comes into close contact with the back of the care recipient P. According to such a configuration, it is possible to easily cope with the difference in the physique (thickness) of the care recipient P.

For example, if the contact portion 30 is rotated greatly (the amount of rotation is greatly increased), the tip portion 30a can be greatly pushed forward. As a result, the tip portion 30a can be brought into contact with the back of the care recipient P having a small physique as shown in FIG. Further, as shown in FIG. 6, if the contact portion 30 is rotated a little, the tip portion 30a is pushed forward a little (see reference numeral C shown in FIG. 6), and the care recipient P having a large physique The tip portion 30a can be brought into contact with the back. As described above, the back holding mechanism 20 can adjust the front-back position of the tip portion 30a (the front-back contact position with respect to the back) according to the amount of rotation of the contact portion 30, and therefore, regardless of the physique of the care recipient P. Instead, if the contact portion 30 is rotated, the tip portion 30a can be brought into contact with the back of the care recipient P. According to this, it is not necessary to perform the operation of adjusting the front-rear position of the tip portion 30a separately from the rotation of the contact portion 30 (the operation of adjusting the left-right position of the tip portion 30a). You can easily deal with differences in physique.

Further, the contact portion 30 is rotated even after the tip portion 30a is in contact with the back of the care recipient P, and the tip portion 30a is pressed against the back. At this time, as shown in FIG. 7, a rearward load F acts on the contact portion 30. The load F is decomposed into a load F1 to the right rear and a load F2 to the left rear. Since the contact portion 30 is configured to be movable in the axial direction (left front and right rear) of the rotating shaft 40, it moves to the right rear by the load F1 to the right rear. The interlocking plate 52 and the movable brake portion 53 shown in FIG. 4 move integrally to the right rear with the movement. As a result, the interlocking plate 52 and the movable brake portion 53 approach the fixed brake portion 54 while rotating integrally with the contact portion 30. Further, the spring 55 is compressed between the interlocking plate 52 and the fixed brake portion 54.

When the contact portion 30 is further rotated, the movable brake portion 53 comes into contact with the fixed brake portion 54, as shown in FIG. If the contact portion 30 is to be rotated in this state, a frictional force is generated between the movable brake portion 53 and the fixed brake portion 54. The frictional force regulates the rotation of the movable brake portion 53, the interlocking plate 52, the rotating shaft 40, and the contact portion 30. By pressing the tip portion 30a against the back of the care recipient P until the rotation of the contact portion 30 is restricted in this way, the operation of supporting the back by the back holding mechanism 20 (contact portion 30) is completed.

Here, the weight of the care recipient P may be applied to the contact portion 30 that supports the back of the care recipient P. In such a case, for example, the caregiver may accidentally start the transfer support device 1 suddenly. In such a case, the regulation mechanism 50 regulates the rotation of the contact portion 30 to maintain the front-rear position of the tip portion 30a.

Specifically, when the weight of the care recipient P is applied to the abutting portion 30, a load F acts on the rear side, and a torque is applied due to the influence of the load F to rotate the tip portion 30a toward the left and right outside. Try to move. Further, when the rearward load F acts on the contact portion 30, the contact portion 30 tends to move to the right rearward due to the influence of the load (see the right rearward load F1 shown in FIG. 7). As described above, when the weight of the care recipient P is applied, the contact portion 30 tends to move to the right rear while rotating. At this time, the movable brake portion 53 and the fixed brake portion 54 come into strong contact with each other to generate a frictional force. The regulation mechanism 50 regulates the rotation of the movable brake portion 53, the contact portion 30, and the like by the frictional force.

As described above, the regulation mechanism 50 according to the present embodiment generates a frictional force (braking force) by the rearward load F generated by the care recipient P applying the weight to the abutting portion 30, and abuts the contact portion 30. The rotation of the portion 30 can be regulated. According to this, when the operation of supporting the back by the back holding mechanism 20 is completed (when the contact portion 30 is rotated), the regulation mechanism 50 is the contact portion when the weight of the care recipient P is applied. The rotation of 30 can be regulated. As a result, the regulation mechanism 50 does not perform a special operation (for example, an operation of connecting the pair of left and right contact portions 30 with a belt or appropriately fixing the rotation shaft 40 so as not to rotate). , The rotation of the contact portion 30 can be regulated.

Further, in the present embodiment, by forming the rotation shaft 40 so as to extend in a direction extending outward to the left and right with respect to the front, the contact portion 30 is rotated with the left front and the right rear as the rotation axis directions. I am doing it. According to this, when the care recipient P puts his / her weight on the contact portion 30 (when a load F is applied to the rear), the torque applied to the contact portion 30 can be reduced.

Specifically, as shown in FIG. 9, the rotation locus L1 of the contact portion 30 that rotates with the left front and the right rear as the rotation axis direction has a substantially circular shape in the rear view (right rear view). Further, the tip portion 30a of the contact portion 30 is mainly located on the upper right side of the rotation shaft 40 when pressed against the back of the care recipient P. In such a state, the tangential direction of the rotation locus L1 of the contact portion 30 (the tangential direction of the rotation locus L1 at the portion where the tip portion 30a is located, that is, the direction in which torque is easily applied) is the upper left and the lower right.

On the other hand, since the care recipient P puts his / her weight backward on the contact portion 30, a large load F (see FIG. 7) acts on the contact portion 30 backward. In the present embodiment, the load F acts in a direction different from the tangential direction of the rotation locus L1. According to such a configuration, when the care recipient P puts his / her weight on the contact portion 30, the load acting in the tangential direction of the rotation locus L1 can be reduced. As a result, the torque generated when the care recipient P puts his / her weight can be reduced, so that the regulating mechanism 50 can regulate the rotation of the contact portion 30 with a small frictional force. Thereby, the load applied to the regulation mechanism 50 can be reduced. Further, since the braking force (braking torque) required for the regulation mechanism 50 can be reduced, the configuration of the regulation mechanism 50 can be simplified.

Further, the regulation mechanism 50 urges the movable brake portion 53 in the direction away from the fixed brake portion 54 by the spring 55. According to this, it is possible to prevent the movable brake portion 53 from coming into contact with the fixed brake portion 54 while the contact portion 30 is brought into contact with the back of the care recipient P. As a result, it is possible to prevent the rotation of the contact portion 30 from being restricted while the contact portion 30 is brought into contact with the back of the care recipient P.

As described above, the transfer support device 1 according to the present embodiment is a transfer support device 1 provided with a back surface holding mechanism 20 (holding mechanism) that supports the back by contacting the back of the care recipient P. The back surface holding mechanism 20 is formed so as to rotatably support the contact portion 30 capable of contacting the back and the contact portion 30 and to extend in a direction extending outward to the left and right with respect to the front. A rotating shaft 40 is provided, and the rotation of the contact portion 30 can regulate the rotation of the contact portion 30 and the adjusting portion that adjusts the contact position of the contact portion 30 with respect to the back in the front-rear direction. It is provided with a regulatory mechanism 50.

With this configuration, the torque applied to the contact portion 30 when the care recipient P puts his / her weight on the contact portion 30 can be reduced. As a result, the rotation of the contact portion 30 can be regulated with a small force (friction force generated between the movable brake portion 53 and the fixed brake portion 54), so that the regulation mechanism 50 that regulates the rotation of the contact portion 30 is reached. The load can be reduced.

Further, the regulation mechanism 50 regulates the rotation of the contact portion 30 when the weight of the care recipient P is applied to the contact portion 30.

With this configuration, the rotation of the contact portion 30 is restricted by the load (load F to the rear) generated by the care recipient P applying his / her weight to the contact portion 30, and the contact position (tip). The front-rear position of the portion 30a) can be maintained. According to this, the contact position can be maintained without performing a special operation for restricting the rotation of the contact portion 30.

Further, the regulation mechanism 50 has an interlocking plate 52 (interlocking member) that interlocks (rotates) in response to the rotation of the abutting portion 30, and a case 51 that does not interlock with the abutting portion 30 and the interlocking plate 52. When the weight of the care recipient P is applied to the right rear portion (first fixing member) and the contact portion 30, the relative movement (rotation) of the interlocking plate 52 with respect to the right rear portion of the case 51 is restricted. It is provided with a movable brake unit 53 and a fixed brake unit 54 (first regulation unit).

With such a configuration, the rotation of the contact portion 30 can be regulated with a simple configuration.

Further, when the weight of the care recipient P is applied to the contact portion 30, the interlocking plate 52 approaches the right rear portion of the case 51, and the movable brake portion 53 and the fixed brake portion 54 are said. As the interlocking plate 52 approaches the right rear portion of the case 51, a braking force (friction force between the movable brake portion 53 and the fixed brake portion 54) for regulating the relative movement is generated. ..

With such a configuration, the rotation of the contact portion 30 can be regulated with a simple configuration.

Further, the regulation mechanism 50 further includes a spring 55 (a urging member) that urges the interlocking plate 52 in a direction away from the right rear portion of the case 51.

With this configuration, it is possible to prevent the rotation of the contact portion 30 from being restricted during the adjustment of the contact position (front-rear position of the tip portion 30a). As a result, it is possible to prevent the adjustment from being hindered during the adjustment of the contact position.

The back surface holding mechanism 20 according to the present embodiment is an embodiment of the holding mechanism according to the present invention.
Further, the interlocking plate 52 according to the present embodiment is an embodiment of the interlocking member according to the present invention.
Further, the right rear portion of the case 51 according to the present embodiment is an embodiment of the first fixing member according to the present invention.
Further, the movable brake unit 53 and the fixed brake unit 54 according to the present embodiment are one embodiment of the first regulation unit according to the present invention.
Further, the spring 55 according to the present embodiment is an embodiment of the urging member according to the present invention.

Further, the movable brake portion 53 and the fixed brake portion 54 have the same shape and are made of the same material. With this configuration, the same parts can be used for the movable brake part 53 and the fixed brake part 54, so that the types of parts can be reduced and the cost can be reduced.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above configuration, and various modifications can be made within the scope of the invention described in the claims.

For example, the back surface holding mechanism 20 is applied to the transfer support device 1, but the present invention is not limited to this, and may be applied to other devices.

Further, the regulation mechanism 50 is not limited to the present embodiment as long as the rotation of the contact portion 30 that supports the back of the care recipient P can be regulated. The regulation mechanism 50 may be, for example, a pin or the like that is engaged with the rotation shaft 40 while the back of the care recipient P is supported by the contact portion 30 to regulate the rotation.

Further, the regulation mechanism 50 does not necessarily have to regulate the rotation of the contact portion 30 when the care recipient P puts his / her weight on the movable brake portion 53 and the fixed brake portion 54. In this case, the regulation mechanism 50 makes, for example, the case 51 and the interlocking plate 52 made of a material having a high coefficient of friction, and brings the interlocking plate 52 into contact with the inner surface of the case 51 when the care recipient P puts his / her weight on it. May restrict the rotation of the contact portion 30 with. With this configuration, the number of parts (movable brake unit 53 and fixed brake unit 54) provided in the case 51 can be reduced, so that the case 51 can be miniaturized, and the regulation mechanism 50 can be miniaturized. can do.

Further, the configuration of the back holding mechanism 20 is not limited to this embodiment, and for example, as in the back holding mechanism 120 according to the modified example shown in FIG. 10, the front movable brake portion 61 and the front fixed brake portion 62 It may be configured to include. The front movable brake portion 61 is fixed to the front surface of the interlocking plate 52. The front movable brake portion 61 is made of a material having a friction coefficient higher than that of the interlocking plate 52 and lower than that of the movable brake portion 53. The front fixed brake portion 62 is formed in the same shape as the front movable brake portion 61. The front fixed brake portion 62 is arranged on the left front side of the front movable brake portion 61 and is fixed to the inner side surface (left front portion) of the case 51. The front fixed brake portion 62 is made of a material having a friction coefficient higher than that of the case 51 and lower than that of the fixed brake portion 54. In the modified example, the front fixed brake portion 62 is made of the same material as the front movable brake portion 61.

As shown in FIG. 10A, the front movable brake portion 61 according to such a modified example is left by the urging force of the spring 55 when the contact portion 30 is not in contact with the back of the care recipient P. It is urged forward and comes into contact with the front fixed brake portion 62. According to such a configuration, when the contact portion 30 is not in contact with the back of the care recipient P and the contact portion 30 tries to rotate due to its own weight, the front movable brake portion 61 and the front fixed brake A frictional force can be generated between the unit and the portion 62. As a result, the back surface holding mechanism 120 according to the modified example can prevent the contact portion 30 from wobbling due to its own weight when the contact portion 30 is not in contact with the back of the care recipient P. As shown in FIG. 10B, when the contact portion 30 is pressed against the back of the care recipient P, the front movable brake portion 61 is pressed from the front fixed brake portion 62 against the urging force of the spring 55. Separate.

As described above, the back surface holding mechanism 20 according to the modified example is arranged on the opposite side of the right rear portion of the case 51 with the interlocking plate 52 interposed therebetween, and is not interlocked with the abutting portion 30 and the interlocking plate 52. As the left front portion (second fixing member) and the interlocking plate 52 approach the left front portion of the case 51, a braking force for regulating the relative movement of the interlocking plate 52 with respect to the left front portion of the case 51 is applied. It further includes a front side movable brake part 61 and a front side fixed brake part 62 (second regulation part) to be generated.

With this configuration, when the contact portion 30 is not in contact with the back, the front movable brake portion 61 and the front fixed brake portion 62 can make it difficult for the contact portion 30 to rotate. As a result, it is possible to prevent the contact portion 30 from wobbling when the contact portion 30 is not in contact with the back.

The left front portion of the case 51 according to the modified example is an embodiment of the second fixing member according to the present invention.
Further, the front movable brake portion 61 and the front fixed brake portion 62 according to the modified example are one embodiment of the second regulation portion according to the present invention.

Also in the back holding mechanism 120 according to such a modification, the front movable brake portion 61 and the front fixed brake portion 62 are formed of the same shape and the same material as the front movable brake portion 61 and the front fixed brake portion 62. The same parts can be used for 62. Therefore, the cost can be reduced.
