In the transfer support apparatus 1 configured as described above, the operations of the tilting actuator 23 of the riding section tilting mechanism 20 and the lifting actuator 33 of the riding section 30 are controlled by operating an operation section (not shown). The said operation part is suitably arrange | positioned in the position where a caregiver (person who assists a care receiver's transfer) is easy to operate.

Next, the operation of the transfer support apparatus 1 configured as described above will be described with reference to FIGS.

As shown in FIG. 3, the elevating member 32 can be slid (lifted) in the longitudinal direction with respect to the riding section body 31 by extending and retracting the lifting actuator 33 of the riding section 30. Since the elevating member 32 is provided with the seating part 34 and the upper body holding part 35, the seating part 34 and the upper body holding part 35 are also raised and lowered together with the elevating member 32. The raising / lowering position (height) of the riding section 30 can be arbitrarily adjusted by adjusting the length of the raising / lowering actuator 33.

Further, as shown in FIG. 4, when the tilting actuator 23 of the riding section tilting mechanism 20 is extended, the second support 22 connected to the tilting actuator 23 slides upward. As a result, the second rotation center P2 moves upward. Along with this, the riding part 30 (the riding part main body 31) connected to the second support part 22 at the second turning center P2 also moves upward. It is connected to the connecting

rods

24 and 24 at the center P3, and its upward movement is restricted. Accordingly, the riding portion 30 is tilted forward (inclined) by the connecting

rods

24 and 24 via the third rotation center P3 while being pushed upward by the second support portion 22 via the second rotation center P2. (The upper end portion of the riding section main body 31 is tilted forward and downward). In this way, when the tilting actuator 23 is extended, the riding section 30 tilts forward. The inclination angle of the riding section 30 can be arbitrarily adjusted by adjusting the length of the inclination actuator 23.

In this case, as shown in the circles in FIGS. 2 and 4, by moving the second rotation center P2 slightly, a straight line L (which connects the second rotation center P2 and the third rotation center P3) ( The straight line L can mean a large inclination of the riding section 30). As described above, the configuration in which the straight line L can be largely tilted with respect to the movement of the second rotation center P2, and the tilt actuator 23 for moving the second rotation center P2 and the compact structure associated therewith. Can be achieved.

In addition, when returning the inclined boarding part 30 (state of FIG. 4) to the original state (state of FIG. 2), the inclination actuator 23 is contracted contrary to the above. As a result, the second support portion 22 slides downward, and the posture of the riding portion 30 returns.

Next, using FIG. 5 and FIG. 6, a state when the cared person 2 is actually transferred using the transfer support apparatus 1 will be described. Here, as an example, a description will be given assuming that the cared person 2 is transferred from the bed 3 to the toilet. For convenience of explanation, illustration of an assistant who operates the transfer support apparatus 1 is omitted.

Moreover, when moving the transfer assistance apparatus 1, the height of the cared person 2 can be adjusted by adjusting the height of the seat part 34 and the upper body holding part 35. For example, by matching the height of the caregiver's line of sight with the height of the line of the care recipient 2, it is possible to perform a conversation or the like while moving without giving an intimidating feeling to the care recipient 2. Moreover, the fear at the time of moving the transfer assistance apparatus 1 by height can be relieved by making the height of the care receiver 2 as low as possible.

Next, as shown in FIG. 6B, the assistant tilts the riding section 30 forward. In this state, most of the weight of the cared person 2 is supported by the upper body holding part 35, and the weight of the cared person 2 is hardly applied to the seating surface 34 b of the seating part 34. In this state, the caregiver can remove the seat surface 34b and easily remove the clothes worn by the care receiver 2 on the lower body.

Thereafter, the caregiver attaches the seating surface 34b to the transfer support device 1 again, returns the posture of the riding section 30 to the original position (see FIG. 6A), moves the transfer support device 1 to the vicinity of the toilet, and the cared person Sit 2 in the toilet seat.
In this case, if the seat surface 34b in which a hole is formed in the center portion is used, the cared person 2 is placed by placing the seat surface 34b in a state where the cared person 2 is seated on the toilet seat of the toilet. The transfer of is completed. The cared person 2 can add work through the hole formed in the seating surface 34b.

In the present embodiment, as described above, the transfer from the bed 3 to the toilet has been described as an example. However, the transfer support device 1 is also used for other transfers (for example, transfer between the bed 3 and the wheelchair). Is possible. Also in this case, the cared person 2 can be easily transferred by getting on and off the cared person 2 together with the seating surface 34b.

Next, with reference to FIG. 16 to FIG. 22, a state when the care receiver (care recipient P) is transferred using the transfer support device configured as described above will be described. Here, as an example, description will be made assuming that the care recipient P is transferred from the bed 200 to another place. For convenience of explanation, illustration of an assistant who operates the transfer support apparatus is omitted.

First, as shown in FIG. 16A, the caregiver places the seat surface portion 102 on the bed 200 and seats the cared person P thereon. At this time, the elevating actuator 180 of the transfer assisting device is extended so that the elevating member 190 is positioned below the connecting portion 152 of the receiving member 150 (see FIG. 13).

Next, as shown in FIG. 16B, the assistant moves the transfer support device (main body unit 101) and connects the seat surface unit 102 to the main body unit 101 via the connection mechanism 103. Hereinafter, the situation at this time will be described in detail.

As shown in FIG. 18, the assistant moves the main body 101 of the transfer support device to insert the connecting portion 143 of the seat surface portion 102 into the receiving portion 152 a of the connecting portion 152. At this time, if the height of the receiving portion 152a of the connecting portion 152 does not coincide with the height of the connecting portion 143 of the seating surface portion 102, the assistant can hold the connecting portion 152 and slide it up and down. Can be combined. Further, since the rear end portion of the receiving portion 152a is wide in the vertical direction, even if the height of the connecting portion 143 of the receiving portion 152a and the seat surface portion 102 is slightly different, the receiving portion 152a of the connecting portion 143 is received. Can be easily guided to.

When the connecting portion 143 of the seat surface portion 102 is inserted into the receiving portion 152a, the connecting portion 143 comes into contact with the rear end surface of the holding member 170. However, since the rear end surface of the holding member 170 is formed to be inclined, the holding member 170 is pushed by the connecting portion 143 and rotates upward. As a result, the holding member 170 is released upward, so that the connecting portion 143 can enter the receiving portion 152a forward.

As shown in FIG. 19, when the assistant moves the main body 101 further rearward, the connecting portion 143 of the seat surface portion 102 is inserted to the back of the receiving portion 152a (near the front end portion). As a result, when the connecting portion 143 is positioned in front of the rear end portion of the holding member 170 protruding downward, the holding member 170 rotates downward again. At this time, as shown in FIG. 20, the rear end portion of the holding member 170 rotated downward is engaged with a notch portion 143 a formed in the connecting portion 143 of the seat surface portion 102. In this way, the holding member 170 is engaged with the connecting portion 143 of the seat surface portion 102, whereby the connecting portion 143 is held by the receiving portion 152a (a drop-off from the receiving portion 152a is prevented). That is, in this state, the seat surface portion 102 cannot be removed from the connecting portion 152 unless the assistant manually rotates the holding member 170 upward to release the engagement with the connecting portion 143.

In addition, as shown in FIG. 20A, in a state where the connecting portion 143 of the seat surface portion 102 is inserted to the back of the receiving portion 152a, the arm 142 of the seat surface portion 102 is inserted into the support member 160, It is supported by the support member 160. In this way, by supporting the arm 142 with the support member 160, the seat surface portion 102 on which the care receiver P is seated can be firmly supported.

Next, as shown in FIG. 21, the caregiver contracts the lifting actuator 180 and moves (lifts) the lifting member 190 upward. The rear end portion (the portion protruding upward) of the elevating member 190 enters the connecting portion 152 through the notch portion 152b of the connecting portion 152, and the upper end surface 191 of the elevating member 190 is the seat surface portion 102. The connecting portion 143 contacts from below. Since the upper end surface 191 of the elevating member 190 is formed so as to incline from the rear upper side toward the front lower side, the connecting portion 143 of the seat surface portion 102 is further forward (receiving portion) by the upper end surface 191 (inclined surface). To the back of 152a. As a result, the connecting portion 143 is more firmly held by the receiving portion 152a. As described above, the connecting portion 143 of the seat surface portion 102 is received by the receiving portion 152a, and the seat portion 102 is held by the holding member 170 and the lifting member 190, whereby the seat surface portion 102 is connected to the main body portion via the connecting mechanism 103. 101 can be connected. In particular, in the present embodiment, since the upper end surface 191 is formed in a shape along the outer periphery of the connecting portion 143 (a shape close to an arc shape), it is possible to suppress the play of the connecting portion 143.

When the assistant further contracts the lifting / lowering actuator 180 to raise the lifting / lowering member 190, the connecting portion 143 is pushed up from below by the lifting / lowering member 190, and the seat surface portion 102 and the connecting mechanism 103 are integrally formed. To rise. At this time, although not shown in FIG. 22, the lifting member 132 (see FIG. 10) of the upper body holding part 130 that is in contact with the upper surface of the connection part 152 of the connection mechanism 103 is also pushed up to the connection mechanism 103. And rises together with the connecting mechanism 103. In this way, the seat surface portion 102 and the upper body holding member 133 can be raised integrally (see FIG. 11). That is, the cared person P seated on the seat surface portion 102 can be lifted from the bed 200 while being held by the upper body holding member 133.

As described above, after the seat surface portion 102 is connected to the main body portion 101 and the seat surface portion 102 is lifted from the bed 200 (see FIG. 16 (b)), the assistant, as shown in FIG. 17 (a), By moving the transfer support device (main body 101), it can be carried to any other place. Also at this time, the connecting portion 143 of the seat surface portion 102 remains held by the receiving portion 152a by the holding member 170 and the elevating member 190 (see FIG. 22), so that the seat surface portion 102 is not likely to drop off.

Further, when the seat surface portion 102 is removed from the main body portion 101 again, for example, when the care recipient P is seated on the other bed 200, the caregiver extends and lowers the lift actuator 180 as shown in FIG. The member 190 is lowered and the seat surface portion 102 is placed on the other bed 200. The assistant can further lower the elevating member 190 to separate the elevating member 190 from the connecting portion 143 of the seat surface portion 102 and release the holding of the connecting portion 143 by the elevating member 190.

Here, the seat surface portion 102 and the coupling mechanism 103 are not fixed to the elevating member 190 but are only supported by being lifted from below by the upper end surface 191 of the elevating member 190. For this reason, even if an obstacle (for example, an object or a person's hand) is sandwiched between the seat surface portion 102 and the bed 200, the driving force by which the elevating actuator 180 extends is transmitted to the seat surface portion 102. Therefore, it is possible to prevent an excessive load from being applied to the obstacle, and there is no possibility of damaging the obstacle.

Further, in this state, the assistant manually rotates the holding member 170 upward to release the engagement with the connecting portion 143, so that the connecting portion 143 can be extracted from the receiving portion 152a. In this state, the assistant can move the main body portion 101 to remove the seat surface portion 102 from the coupling mechanism 103.

If there is no bed 200 (see FIG. 23) or the like on which the seat surface portion 102 can be placed as in the above example, the elevating member 190 is lowered and the slide portion 151 of the coupling mechanism 103 is brought into contact with the stopper 131d. By doing so, the descent of the slide portion 151 is restricted, and the elevating member 190 can be separated from the connecting portion 143 of the seat surface portion 102. Thereby, when the cared person P is not seated on the seat surface portion 102, the seat surface portion 102 can be removed at an arbitrary place.

Next, with reference to FIG. 12 and FIG. 17, a state when the care receiver P attaches / detaches the clothes worn on the lower body by using the transfer support device will be described.

First, as shown in FIG. 12, the caregiver drives the tilt actuator 123 while the cared person P (not shown in FIG. 12) is seated on the seat surface portion 102, and sets the second support portion 122 to the first position. It is slid (raised) upward with respect to the support part 121. Along with this, the holding portion main body 131 connected to the second support portion 122 also tries to rise, but since the rising is restrained by the connecting rod 124, the holding portion main body 131 is inclined (tilted) forward. To do.

In this state, as shown in FIG. 17B, the weight of the cared person P is mainly supported by the upper body holding unit 130. In this state, the seat surface portion 102 can be detached from the main body portion 101 by releasing the holding of the seat surface portion 102 by the elevating member 190 and the holding member 170 in the same manner as described above.

Further, the configuration of the holding member according to the present invention is not limited to the holding member 170 according to the present embodiment. For example, in the present embodiment, the holding member 170 is engaged with the connecting portion 143 from above the connecting portion 143 (see FIG. 19 and the like), but may be configured to be engaged from below. Further, a biasing member (a spring or the like) that biases the holding member 170 so as to always rotate in the direction in which the holding member 170 is engaged with the connecting portion 143 may be provided. Further, an operation unit (a handle or the like) may be provided so that an assistant can easily operate the holding member 170 when the holding by the holding member 170 is manually released.

Further, the configuration of the lifting mechanism according to the present invention is not limited to the lifting mechanism 104 according to the present embodiment. For example, in the present embodiment, the elevating actuator 180 is an extendable cylinder, but it may be configured by a motor or the like. Moreover, the shape of the raising / lowering member 190 should just be a shape which can push up the seat surface part 102 from the downward direction.

Further, in the present embodiment, the elevating member 190 is configured to abut against the connecting portion 143 of the seat surface portion 102 from below and to raise the seat surface portion 102 by pushing up the connecting portion 143. It is not limited to. For example, the elevating member 190 may be configured to abut against the connecting mechanism 103 (for example, the connecting portion 152) from below and raise the seat surface portion 102 by pushing up the connecting portion 152.

In the present embodiment, the upper end surface 191 of the elevating member 190 is rearwardly and upwardly so that the elevating member 190 is held by the receiving portion 152a when the elevating member 190 contacts the connecting portion 143 of the seat surface portion 102. Although formed so as to incline toward the front lower side, the shape of the upper end surface 191 (inclined surface) can be arbitrarily set. For example, the upper end surface 191 (inclined surface) may be linear or curved, and a linear surface and a curved surface may be combined.

In the present embodiment, the lifting member 132 of the upper body holding unit 130 is in contact with the upper surface of the receiving member 150 (the coupling unit 152), and the receiving member 150 is lifted and lowered by the lifting mechanism 104. Although the elevating member 132 of the portion 130 is also configured to move up and down (see FIG. 10 and the like), the elevating member 132 and the receiving member 150 may be fixed to each other.

The present invention can be applied to a transfer support device that supports transfer of a care recipient.
