Description

The present invention relates to a technique of a transfer support device that supports the transfer of a care recipient.

Conventionally, the technology of a transfer support device that supports the transfer of a care recipient has been known. For example, as described in Patent Document 1.

The transfer support device described in Patent Document 1 is connected to a main body portion arranged in front of the care recipient, an arm having one end rotatably supported by the main body portion, and the other end portion of the arm. , A support portion that supports the upper body of the care recipient from the front (chest side). The transfer support device swings the support portion back and forth by rotating one end portion of the arm.

The support portion described in Patent Document 1 is swung backward when the care recipient is boarded (holds the upper body). At this time, the support portion is swung so as to be rearward and downward around one end of the arm. For this reason, the height position (vertical position) of the support portion becomes low, and the support portion is arranged at a low position with respect to the care recipient (in a posture of sitting on a wheelchair or the like) before boarding. In this case, the care recipient cannot board the transfer support device unless he / she leans forward significantly. Therefore, in the transfer support device, there is a possibility that the burden on the body of the care recipient becomes large.

The base frame 11 is a member forming the main body portion of the bogie portion 10. The base frame 11 is formed by appropriately combining a substantially rod-shaped member, a substantially plate-shaped member, and the like. A plurality of wheels 12 are provided below the base frame 11. The step 13 is a flat plate-shaped member that forms a scaffold for the care recipient A boarding the transfer support device 1, and is provided in the middle of the front and rear of the base frame 11.

The support portion 20 is provided on the upper portion of the bogie portion 10 and is for supporting the chest frame 30, which will be described later. The support portion 20 includes a lower leg frame 21, an upper body frame 22, a seating portion 23, and a handle portion 24.

The lower leg frame 21 is a portion forming the left portion and the right portion of the support portion 20. The lower leg frame 21 is formed in a substantially plate shape with its plate surface oriented in the left-right direction. The lower leg frame 21 is formed in a shape obtained by rotating a substantially L-shape by 180 ° in the left side view. The lower leg frames 21 are formed in pairs on the left and right. The lower end of the lower leg frame 21 is subsequently connected to the bogie portion 10 (base frame 11) via the swing shaft 21a. As a result, the lower leg frame 21 is supported so as to be swingable back and forth with respect to the bogie portion 10. A linear straight rail 21b (see FIG. 4) extending in the front-upward direction is fixed to the inner surface of the lower leg frame 21 configured in this way.

As shown in FIGS. 1 and 4, the upper body frame 22 is a portion forming the left and right central portions of the support portion 20. The upper body frame 22 is formed in a substantially plate shape with its plate surface oriented in the left-right direction and its longitudinal direction directed in the front-up direction (rear-downward direction). The upper body frame 22 is formed in pairs on the left and right. The upper body frame 22 is arranged between the pair of left and right lower leg frames 21 (inside) and at the rear upper part of the lower leg frame 21. A straight slider 22a capable of sliding the straight rail 21b is fixed to the lower end of the upper frame 22. As a result, the upper body frame 22 is configured to be relatively movable in the anterior-upper direction and the posterior-downward direction with respect to the lower leg frame 21.

The seating portion 23 is for the care recipient A to sit down. The seating portion 23 is connected to the rear end portion of the lower leg frame 21 and projects rearward from the upper and lower middle portions of the lower leg frame 21.

The handle portion 24 is for the care recipient A to grasp. The handle portion 24 is formed into a shape that is easy to grip by appropriately combining rod-shaped members. The handle portion 24 is fixed to the front end portion of the lower leg frame 21 and projects upward from the lower leg frame 21.

The chest frame 30 shown in FIGS. 2 and 3 is a portion that holds the upper body of the care recipient A. The chest frame 30 is attached to the support portion 20 via a swing mechanism 60 described later, and is arranged above and after the lower leg frame 21. The chest frame 30 includes a front frame 31 and a side frame 32.

The front frame 31 is a portion that holds a portion extending from the chest to the abdomen of the care recipient A. The front frame 31 has an upper body holding surface 31a that holds the upper body of the care recipient A from the chest side. The upper body holding surface 31a is formed in a substantially rectangular shape with its longitudinal direction facing the rear-downward direction (front-upward direction) and its lateral direction facing the left-right direction.

The side frame 32 is a portion that holds the care recipient A from both the left and right sides. The side frame 32 is fixed to the front frame 31 and is formed so as to project rearward and upward from the left and right sides of the front frame 31.

In the chest frame 30 configured in this way, a cushion (not shown) made of a soft material such as urethane is attached to the front frame 31 and the side frame 32. Thereby, the chest frame 30 can reduce the load applied to the care recipient A when the upper body of the care recipient A is held.

The lower leg cylinder 40 shown in FIG. 4 is a drive source for swinging the support portion 20 back and forth with respect to the bogie portion 10. The lower leg cylinder 40 is an actuator that can expand and contract in the longitudinal direction thereof, and in the present embodiment, an electric cylinder is used. The lower leg cylinder 40 is arranged so that its longitudinal direction is directed toward the front-down direction (rear-upward direction). The front lower end portion of the lower leg cylinder 40 is oscillatingly connected to the front portion of the base frame 11 of the bogie portion 10. The rear upper end portion of the lower leg cylinder 40 is swingably connected to the inner surface of the lower leg frame 21 via the connecting member 41. Such a lower leg cylinder 40 can swing the support portion 20 backward by extending it. Further, the lower leg cylinder 40 can swing the support portion 20 forward by contracting.

The upper body cylinder 50 is a drive source for raising and lowering the upper body frame 22 with respect to the lower leg frame 21 (moving it relatively to the front upper side and the rear lower part). The upper body cylinder 50 is an actuator that can expand and contract in the longitudinal direction thereof, and in the present embodiment, an electric cylinder is used. The upper body cylinder 50 is arranged so that its longitudinal direction is directed toward the front-up direction (rear-downward direction). The lower end of the upper body cylinder 50 is connected to the inner surface of the lower leg frame 21 via the connecting member 41. The upper end of the upper body cylinder 50 is connected to the front end of the pair of left and right upper body frames 22. Such an upper body cylinder 50 can raise (move forward and upward) the upper body frame 22 by extending it. Further, the upper body cylinder 50 can lower (move backward and downward) the upper body frame 22 by contracting.

The swing mechanism 60 is for swinging the chest frame 30 back and forth with respect to the lower leg frame 21. As shown in FIGS. 4 to 6, the swing mechanism 60 includes a link 61, an arc frame 62, an arc slider 63, and an arc rail 64. Note that FIG. 6 is a diagram schematically showing the swing mechanism 60 in order to make it easy to see the shape of each part of the swing mechanism 60.

The link 61 is a substantially plate-shaped member whose plate surface is directed in the left-right direction and whose longitudinal direction is directed in the vertical direction. The link 61 is arranged between the pair of left and right upper body frames 22 and is formed so as to extend from the lower portion to the upper end portion of the upper body frame 22. The link 61 is supported by a pair of left and right lower leg frames 21 via a pin 61a inserted through the lower end thereof. As a result, the link 61 swings back and forth with respect to the lower leg frame 21 about the pin 61a.

The arc frame 62 is a substantially plate-shaped member for connecting the chest frame 30 and the link 61. The arc frame 62 is arranged with its plate surface oriented in the left-right direction. Further, the arc frame 62 is formed in a substantially arc shape in a side view. More specifically, the arc frame 62 is formed in a substantially arcuate side view with the position C above the rear end portion of the seating portion 23 as the center of the arc, and in the initial state, the rear upper end of the upper body frame 22 is formed in the side view. It is arranged so as to protrude rearward and upward from the portion. A pair of such arc frames 62 are formed on the left and right sides. The chest frame 30 is fixed to the upper end of the arc frame 62. Further, the arc frame 62 has an upper end portion of the link 61 fixed to the lower end portion on the inner side surface thereof, and is arranged between the pair of left and right upper body frames 22 (between the link 61 and the upper body frame 22). As a result, the arc frame 62 swings back and forth integrally with the link 61. The arc frame 62 can swing the chest frame 30 back and forth along with the swing.

The arc slider 63 slides along an arc rail 64, which will be described later. A pair of left and right arc sliders 63 are formed, and are fixed to the lower ends of the pair of left and right arc frames 62 on the outer surface. As a result, the arc slider 63 is arranged between the pair of left and right upper body frames (between the arc frame 62 and the upper body frame 22), and swings back and forth integrally with the link 61.

The arc rail 64 is a member for guiding the arc slider 63. The arc rail 64 is formed in a substantially arc shape in a side view. More specifically, the arc rail 64 is formed in a substantially arc shape in a side view with the position C (the same position as the center of the arc of the arc frame 62) above the rear end of the seating portion 23 as the center of the arc. In the initial state, it is arranged so as to project downward from the arc frame 62 in the side view. Further, the arc rail 64 is formed so as to extend to the lower end portion of the upper body frame 22. A pair of such arc rails 64 are formed on the left and right, and are fixed to the inner surface of the upper body frame 22. As a result, the arc rail 64 is arranged outside the arc frame 62 with the arc slider 63 interposed therebetween, and moves up and down as the upper body frame 22 moves up and down.

The swing mechanism 60 configured in this way can swing the chest frame 30 back and forth according to the raising and lowering of the upper body frame 22.

In the following, the swinging motion of the chest frame 30 by the swinging mechanism 60 will be described in detail with reference to FIG. 4 and FIGS. 7 to 11.

In the following, a case where the swing operation is performed from the initial state shown in FIGS. 4 and 7 (a) will be described as an example. In the initial state, the swing mechanism 60 swings the chest frame 30 most backward, and the arc slider 63 is located at the upper end of the arc rail 64. Further, the upper body frame 22 is in the most lowered state. Further, the lower leg frame 21 is in a state of swinging most backward. The swing mechanism 60 swings the chest frame 30 forward by performing a swing operation from such an initial state.

More specifically, the swing mechanism 60 starts the swing operation by extending the upper body cylinder 50. When the upper body cylinder 50 is extended, the upper body frame 22 is raised along with the extension. The arc rail 64 rises with the rise. At this time, although the arc slider 63 is pulled by the arc rail 64 and tries to rise, it tries to maintain the distance from the link 61 because it is fixed to the arc frame 62 (link 61). As a result, as shown in FIGS. 7B and 8, the arc rail 64 slides up with respect to the arc slider 63, and the arc slider 63 swings forward about the pin 61a. Along with the swing, the arc frame 62, the link 61, and the chest frame 30 also swing. At this time, the chest frame 30 moves forward.

When the upper body cylinder 50 is further extended from the state shown in FIGS. 7 (b) and 8, the upper body frame 22 is in the most raised state with respect to the lower leg frame 21 as shown in FIGS. 7 (c) and 9. Will be. At this time, the arc rail 64 further slides with respect to the arc slider 63, and the arc slider 63 further swings forward. As a result, the arc frame 62, the link 61, and the chest frame 30 are further swung forward, and are in a state of being swung most forward (a state in which the arc slider 63 is located at the lower end of the arc rail 64). At this time, the chest frame 30 further moves forward and downward. As a result, the swinging operation by the swinging mechanism 60 is completed.

By such a swinging operation, the upper body holding surface 31a of the front frame 31 swings around the pin 61a and its direction can be changed, but it still faces a direction in which it tilts slightly backward with respect to the upward direction. It is in the state of being (not facing upward).

When the lower leg cylinder 40 is driven to swing the support portion 20 forward in such a state, the swing mechanism 60 and the chest frame 30 swing integrally with the support portion 20. As a result, the chest frame 30 is further moved forward and downward. Then, as shown in FIG. 10, when the support portion 20 is swung most forward, the upper body holding surface 31a of the front frame 31 is in a state of facing upward. In such a state, the transfer support device 1 can lift the care recipient A.

The swing mechanism 60 swings the chest frame 30 backward by lowering the upper body frame 22. At this time, the swing mechanism 60 operates in the opposite direction to the case where the upper body frame 22 is raised. That is, the arc rail 64 slides down with respect to the arc slider 63, and the arc slider 63 swings backward. The arc frame 62, the link 61, and the chest frame 30 swing backward (move backward and upward) along with the swing. Further, when the lower leg cylinder 40 is extended, the support portion 20 swings backward. The swing mechanism 60 and the chest frame 30 swing backward along with the swing. The transfer support device 1 is in the initial state when the support portion 20 and the chest frame 30 swing most backward.

As described above, the transfer support device 1 according to the present embodiment can swing the chest frame 30 back and forth not only by the lower leg cylinder 40 that swings the support portion 20 but also by the swing mechanism 60. According to this, the transfer support device 1 can widen the swing range of the chest frame 30 (swing further backward than when swinging only the support portion 20). Therefore, as shown in FIG. 11, the transfer support device 1 can bring the chest frame 30 sufficiently upright in the initial state. As a result, the care recipient A can board the transfer support device 1 without leaning forward significantly. As a result, the transfer support device 1 can reduce the burden on the care recipient A when boarding. In addition, the burden on the caregiver who assists the care recipient A in leaning forward can be reduced.

Further, the swing mechanism 60 swings the chest frame 30 by sliding the arc slider 63 with respect to the arc rail 64 by utilizing the raising and lowering of the upper body frame 22. As a result, the swing mechanism 60 receives the weight of the care recipient A not only by the pin 61a but also by the arc rail 64. Thereby, the load applied to the pin 61a can be distributed.

Further, in the swing mechanism 60 according to the present embodiment, the arc rail 64 is formed to be heavier than the arc slider 63. In such a configuration, the swing mechanism 60 fixes the arc rail 64 to the upper frame 22 arranged on the lower side of the upper frame 22 and the arc frame 62. This makes it possible to improve the weight balance.

Further, the chest frame 30 is configured such that the swing center (pin 61a) is located substantially below the chest frame 30 in the initial state. According to this, the swing mechanism 60 can greatly move the chest frame 30 forward immediately after starting swinging forward from the initial state. As a result, the swing mechanism 60 can increase the amount of movement of the chest frame 30 in the front-rear direction, so that the waist of the care recipient A can be easily lifted.

Further, the swing mechanism 60 can easily change the swing speed of the chest frame 30 by using the arc rail 64. For example, when the upper body frame 22 rises by a certain distance from the initial state shown in FIG. 7A, the arc slider 63 slides greatly with respect to the arc rail 64, and the chest frame 30 swings greatly. On the other hand, when the upper body frame 22 shown in FIG. 7B is raised to some extent and then rises by a certain distance, the arc slider 63 slides slightly with respect to the arc rail 64, and the chest frame 30 swings slightly. As described above, when the arc rail 64 is used, the amount of swing of the chest frame 30 with respect to the rise of a certain distance (the amount of rise per unit distance) can be changed according to the positional relationship with the arc slider 63. According to this, the swing speed of the chest frame 30 can be changed by expanding and contracting the upper body cylinder 50 at a constant speed. Thereby, the swing speed of the chest frame 30 can be easily changed without controlling the expansion / contraction speed of the upper body cylinder 50. In such a configuration, by forming the arc rail 64 into an arc having a shape according to the purpose, it is possible to obtain a target swing speed without performing complicated control.

Further, as shown in FIG. 11, the upper body holding surface 31a of the front frame 31 is arranged in the longitudinal direction thereof in the rear-downward direction (front-upward direction) in the initial state. The upper body holding surface 31a is formed so as to extend toward the center of the arc of the arc rail 64 (position C above the rear end portion of the seating portion 23) (see the arrow shown in FIG. 11). The center of such an arc corresponds to the position of the waist of the care recipient A who has boarded the transfer support device 1 in the initial state. According to this, when the care recipient A gets on board, the upper body of the care recipient A and the chest frame 30 can be easily aligned. As a result, when the care recipient A is on board, the burden on the care recipient A's body can be reduced.

As described above, the transfer support device 1 according to the present embodiment includes a movable trolley portion 10, a lower leg frame 21 (main body portion) oscillatingly supported by the trolley portion 10, and the lower leg frame 21. A support portion 20 having an upper body frame 22 (sliding portion) that is slidably supported, and a chest frame 30 (upper body holding portion) that is attached to the lower leg frame 21 and holds the upper body of the care recipient A. ) And a swing mechanism 60 that swings the chest frame 30 back and forth with respect to the lower leg frame 21, and the swing mechanism 60 is either the upper body frame 22 or the chest frame 30. The arc rail 64 (rail) fixed to one side and the upper body frame 22 or the chest frame 30 are fixed to the other, and slide with respect to the arc rail 64 as the upper body frame 22 slides. By doing so, the arc slider 63 (slider) that swings the chest frame 30 is provided.

With this configuration, the swingable range of the chest frame 30 can be expanded by the support portion 20 and the swing mechanism 60. As a result, the chest frame 30 can be fully upright. As a result, the care recipient A can be boarded without being tilted forward so much, so that the burden on the care recipient A's body can be reduced.

Further, the arc rail 64 is fixed to the upper body frame 22, and the arc slider 63 is fixed to the chest frame 30.

With this configuration, the swingable range of the chest frame 30 can be expanded.

Further, the arc rail 64 is formed in a side view arc shape.

With this configuration, the swing amount per unit lift amount (unit slide amount) can be changed according to the positional relationship between the arc rail 64 and the arc slider 63.

Further, the seating portion 23 on which the care recipient A is seated is further provided, and the arc rail 64 is in an initial state (rear swinging state) in which the support portion 20 and the chest frame 30 are swung most backward. The center of the arc is arranged at the position of the waist of the care recipient A seated on the seat 23 (position C above the rear end of the seat 23).

With such a configuration, the burden on the body of the care recipient A can be reduced.

Further, the chest frame 30 has an upper body holding surface 31a for holding the upper body of the care recipient A from the chest side, and in the initial state, the upper body holding surface 31a is directed toward the center of the arc. It is formed to extend.

With such a configuration, it is possible to easily align the upper body of the care recipient A with the chest frame 30 when the care recipient A is on board. As a result, the burden on the body of the care recipient A can be effectively reduced.

The lower leg frame 21 according to the present embodiment is an embodiment of the main body according to the present invention.
Further, the upper body frame 22 according to the present embodiment is an embodiment of the sliding portion according to the present invention.
Further, the chest frame 30 according to the present embodiment is an embodiment of the upper body holding portion according to the present invention.
Further, the arc rail 64 according to the present embodiment is an embodiment of the rail according to the present invention.

Further, the swing mechanism 60 includes an arc frame 62 that is fixed to the chest frame 30 and is formed so as to protrude rearward and upward (chest side of the care recipient A) from the arc rail 64 in the initial state. be. With this configuration, the chest frame 30 can be fully upright in the initial state. As a result, the care recipient A does not have to lean forward so much when boarding the transfer support device 1, so that the burden on the care recipient A's body can be effectively reduced.

Further, the arc slider 63 is fixed to the arc frame 62. With this configuration, the arc frame 62 can be slid with respect to the arc rail 64 together with the arc slider 63. According to this, when the chest frame 30 is swung forward, the arc frame 62 can be arranged at a position where it overlaps with the arc rail 64 in a side view (see FIG. 9). Therefore, it is possible to contribute to space saving of the swing mechanism 60.

Further, the arc frame 62 is formed in a substantially arc shape in a side view so that the center of the arc coincides with the center of the arc rail 64 in the initial state. With this configuration, when the chest frame 30 is swung forward, the arc rail 64 can be prevented from protruding back and forth with respect to the arc frame 62. As a result, the entire arc rail 64 can be easily arranged at a position where it overlaps with the arc frame 62 in a side view, which can contribute to space saving of the swing mechanism 60.

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 swing mechanism 60 swings the chest frame 30 by the upper body cylinder 50, but the drive source for swinging the chest frame 30 is not limited to this, for example, a link. The chest frame 30 may be swung by a motor or the like that rotates the 61.

Further, the arc slider 63 is attached to the arc frame 62, but is not limited to this as long as it is attached to at least a member on the arc frame 62 side, and is attached to, for example, the chest frame 30. May be good.

Further, in the initial state, the arc rail 64 is arranged so that the center of the arc is located at the waist position of the care recipient A seated on the seat portion 23 (position C above the rear end portion of the seat portion 23). However, it is not limited to this. The arc rail 64 can have an arbitrary position as the center of the arc if the chest frame 30 can be sufficiently upright in the initial state.

Further, the swing mechanism 60 swings the chest frame 30 by using a rail (arc rail 64) having a substantially arc shape in a side view, but the present invention is not limited to this, and for example, a linear rail. May be used to swing the chest frame 30. With this configuration, the chest frame 30 can be swung using a member that is cheaper than the arc rail 64, so that the cost can be reduced.

Further, the upper body frame 22 is designed to move up and down with respect to the lower leg frame 21, but is not limited to this as long as it is slidable with respect to the lower leg frame 21, for example, the lower leg frame 21. On the other hand, it may slide back and forth.
