  Patent Document 1 describes a transfer support device that includes a movable carriage, a seating portion on which a cared person sits, and a support member that supports the seating portion. In the transfer support device, by swinging the support member up and down, the position of the seating portion is a storage position stored in the lower portion (cart body) of the carriage, and a seating position where the care receiver can sit. , Can be switched. When the care receiver transfers, the transfer operation can be easily performed by switching the position of the seating portion to the storage position or the seating position as appropriate.

  However, in the technique described in Patent Document 1, although the position of the seating portion can be switched, the size and the shape of the seating portion itself do not change. Therefore, when switching the position of the seating portion, the seating portion which is large enough to allow the care receiver to sit is swung. For this reason, when a cared person transfers, there is a possibility that a body (feet etc.) may hit the said seating part, and it was disadvantageous at the point where transfer work may be difficult to perform.

The holding member 62 is formed in a substantially U shape whose rear is open in a plan view. The holding member 62 can hold the upper body (in particular, the chest) of the care recipient so as to surround the upper side and the left and right sides. The holding member 62 is fixed to the rear side surface of the holding portion main body 61.

Next, a method of switching the position of the seating portion 20 between the seating position and the storage position in the transfer assist device 1 configured as described above will be described using FIGS. 5 to 8.
Here, the “seating position” is a position where the cared person can sit on the seating portion 20 (see FIG. 5), more specifically, the axis lines of the left rotation shaft 21a and the right rotation shaft 22a are back and forth It is a position facing the direction. In addition, the “storage position” is a position where the care receiver can not sit on the seating portion 20 (see FIG. 8), more specifically, the axis lines of the left rotation shaft 21a and the right rotation shaft 22a are in the vertical direction It is a position to face the

  As shown in FIG. 5, when the seating portion 20 is in the seating position, the seating portion 20 is fitted to the notch 12 b of the support portion 12 and fixed in the seating position.

  More specifically, the left seating portion 21 and the right seating portion 22 are slid forward with the plate surfaces directed vertically. The front end portions of the left seat 21 and the right seat 22 are fitted (fitted) into the cutout 12 b. Thus, the rotation of the left seat 21 around the left rotation shaft 21 a and the rotation of the right seat 22 around the right rotation shaft 22 a are restricted. Further, the rotation around the rotation shaft 31 of the rotation support portion 30 is restricted. Thus, the seating portion 20 is fixed at the seating position.

  At this time, the seating portion 20 is formed in a single plate shape by the left seating portion 21 and the right seating portion 22. Further, a substantially horizontal plane (seating surface) having a substantially rectangular shape in plan view is formed by the upper surface of the left seat 21 and the upper surface of the right seat 22. The cared person can be seated on the seating surface of the seating portion 20. Hereinafter, the state of the seating portion 20 is simply referred to as a "seating state".

  When the position of the seating portion 20 is switched from the seating position to the storage position, first, as shown in FIG. 6, the left seating portion 21 and the right seating portion 22 are slid rearward. As a result, the left seat 21 and the right seat 22 come out of the notch 12b. At this time, the left seat 21 and the right seat 22 are prevented from coming off the pivot support 30 by the left catch 21 b and the right catch 22 b coming into contact with the pivot support 30.

  Next, as shown in FIG. 7, the left seat 21 is pivoted 90 degrees clockwise in a front view about the left pivot shaft 21a. Further, the right seating portion 22 is pivoted 90 degrees counterclockwise in a front view about the right pivot shaft 22a. That is, the left seat 21 and the right seat 22 are turned so that the left and right outer ends of the left seat 21 and the right seat 22 face downward. Thus, the plate surface of the left seat 21 and the plate surface of the right seat 22 face each other. In this way, a single plate-like seating 20 (see FIG. 5) can be folded in half. Hereinafter, the state of the seating portion 20 is simply referred to as a "folded state". Under the present circumstances, since the plate surface of the left side seating part 21 and the right side seating part 22 is turned to the left-right direction, the left-right direction width of the seating part 20 becomes significantly narrower than before folding (refer FIG. 5).

  Next, as shown in FIG. 8, the left seat 21 and the right seat 22 are pivoted downward 90 degrees about the pivot support 30 (the pivot shaft 31). The left seat 21 and the right seat 22 are inserted into the slit 12 a of the support 12 from the front. Thereby, a part (rear part) of the left seat 21 and the right seat 22 is accommodated in the slit 12a. Thus, the position of the seating portion 20 is switched to the storage position (see FIG. 8).

  When the seating portion 20 is in the storage position, the seating portion 20 (the left seating portion 21 and the right seating portion 22) is positioned at the same position as the support 12 in the front-rear direction or in front of the support 12 . That is, in this case, the seating portion 20 is accommodated in the front of the support portion 12, and the seating portion 20 does not protrude rearward relative to the support portion 12. This can prevent the body of the care recipient getting on and off the transfer support device 1 from coming into contact with the seating portion 20.

  Further, in this case, since the seating portion 20 is in the folded state, the width in the left-right direction is narrow. Specifically, the seating portion 20 is narrower than the distance between the left and right feet of the cared person who got into the transfer support device 1 (the distance between the left and right foot support portions 40 and the distance between the left and right knee receiving portions 52) It has become. This can prevent the cared person's body (in particular, the foot) from coming into contact with the seating portion 20.

  Further, in this case, since the left seat 21 and the right seat 22 are partially accommodated in the slit 12a, the seat 20 can be compactly stored. Further, the slit portion 12a restricts the rotation of the left seating portion 21 around the left rotation shaft 21a and the rotation of the right seating portion 22 around the right rotation shaft 22a. As a result, it is possible to prevent the left seat 21 and the right seat 22 from pivoting to the left and right to be in contact with the care recipient's body (in particular, the foot).

  When the position of the seating portion 20 is switched from the storage position to the seating position, the above-described operation (the operation from FIG. 5 to FIG. 8) is performed in the reverse procedure. That is, from the state shown in FIG. 8, the seating portion 20 is pivoted forward and upward by 90 degrees (see FIG. 7). Next, lower end portions of the left seating portion 21 and the right seating portion 22 are pivoted to open laterally (see FIG. 6). Next, the left seat 21 and the right seat 22 are slid forward (see FIG. 6). By this, the position of the seating portion 20 can be switched from the storage position to the seating position.

  Next, with reference to FIG. 3 and FIGS. 9 to 11, the state of the operation (transfer operation) of transferring the care recipient P using the transfer support device 1 configured as described above will be described. Here, as an example, it is assumed that the care receiver P sitting on the toilet 2 is transferred to another place. In addition, illustration of the assistant who operates the transfer assistance apparatus 1 is abbreviate | omitted for convenience of explanation.

  First, the caretaker brings the transfer assistance device 1 with the seating portion 20 in the storage position closer to the front of the care receiver P sitting on the toilet bowl 2 (see FIGS. 9A and 9B). At this time, as shown in FIG. 3, no member is disposed at the rear portion (avoiding portion E) of the traveling portion 11. Therefore, the upper body holding portion 60, the toe support portion 40, and the like can be brought closer to the care recipient P without bringing the traveling portion 11 into contact with the toilet bowl 2.

  Next, the assistant holds the upper body of the care receiver P at the upper body holding portion 60 (see FIG. 9B). Specifically, the assistant inserts the both ends of the holding member 62 of the upper body holding portion 60 into the left and right sides of the care receiver P, respectively. By this, the upper body holding part 60 can support the care recipient P from underarms. At this time, it is possible to make the posture stable by holding the upper body holding portion 60 with both arms of the care receiver P itself. In addition, the assistant puts the toe of the care recipient P on the foot support portion 40 and supports the knee of the care recipient P by the knee support portion 50.

  Next, the assistant turns the upper body holding portion 60 forward about the turning shaft 61a (see FIG. 10A). As a result, the care recipient P can be inclined forward, and the waist of the care recipient P can be floated from the toilet bowl 2. At this time, since the care receiver P is supported by not only the upper body holding unit 60 but also the foot support unit 40 and the knee support unit 50, it is possible to relieve the burden on the care receiver P's body. Further, in this state, since the waist of the care recipient P is floating, the care giver can easily put on and take off the clothes worn on the lower body by the care recipient P. Therefore, the transfer assist device 1 is particularly useful in assisting the excretion of the care receiver P.

  Next, the assistant moves the transfer support device 1 forward so that the transfer support device 1 is separated from the toilet bowl 2 (see FIG. 10B). Then, the assistant switches the position of the seating portion 20 from the storage position to the seating position (see FIGS. 10B and 11A). At this time, since the transfer assist device 1 is separated from the toilet bowl 2, the seat 20 does not come into contact with the toilet bowl 2. Further, at this time, the seating portion 20 is switched to the folded state (see FIG. 10), and since the width in the lateral direction is narrow, when passing between the left and right feet of the care recipient P There is no contact with The assistant switches the position of the seating portion 20 to the seating position, and then switches the seating portion 20 to the seating state (see FIG. 11A).

  Next, the assistant turns the upper body holding portion 60 rearward about the turning shaft 61a (see FIG. 11B). Thus, the care recipient P can be seated on the seating portion 20. The care giver can move the cared person P to an arbitrary place by moving the transfer support device 1 in this state (a state in which the cared person P is in the transfer support device 1).

  When the care recipient P is lowered from the transfer support device 1 and seated in another place (for example, a bed or a wheelchair), the above-described operation (the operation from FIG. 9 to FIG. 11) is performed in the reverse procedure. That is, from the state shown in FIG. 11B, the upper body holding portion 60 is pivoted forward to float the waist of the care recipient P (see FIG. 11A). Next, the position of the seating portion 20 is switched to the storage position, and the transfer assist device 1 is brought close to a desired location (see FIGS. 10B and 10A). Next, the upper body holding portion 60 is rotated backward to seat the care recipient P at a desired position (see FIG. 9B).

As described above, the transfer support device 1 according to the present embodiment

The
By configuring in this manner, the body of the care receiver P becomes difficult to hit the seating portion 20 by turning the seating portion 20 to the seating position or the storage position in the state where the seating portion 20 is switched to the folded state, and thus the transfer operation Can be done easily.
Further, when the seating portion 20 is stored, it is not necessary to remove the seating portion 20 from the transfer assist device 1 (the carriage 10), and the workability can be improved.

In addition, seat section 20,
A left seating portion 21 (first portion) that can rotate around a left rotation shaft 21a (first rotation shaft);
A right seating portion 22 (second portion) rotatable about a right rotation shaft 22a (second rotation shaft) parallel to the left rotation shaft 21a;
Equipped with
While the left seat 21 is pivoted about the left pivot 21a, and the right seat 22 is pivoted about the right pivot 22a, the seat 21 is either in the seat or in the folded state. It can be switched.
By comprising in this way, the seating part 20 which can switch to a seating state and a folding state can be formed easily.

In addition, the rotation support unit 30
The left rotation shaft 21a and the right rotation shaft 22a are supported so as to be rotatable about the axes of the left rotation shaft 21a and the right rotation shaft 22a and slidably in the axial direction,
The notch 12b is

  Moreover, the structure of the trolley | bogie part which concerns on this invention is not restricted to the structure of the trolley | bogie part 10 which concerns on this embodiment. That is, the trolley | bogie part can move on the ground, and should just be able to support other members (a seating part, a rotation support part, a rotation control part, etc.).

  Moreover, the structure of the storage part which concerns on this invention is not restricted to the structure of the slit part 12a which concerns on this embodiment. That is, the storage part should just be a shape in which the seating part switched to the folding state can be stored (insertable).

  Moreover, the structure of the seating part which concerns on this invention is not restricted to the structure of the seating part 20 which concerns on this embodiment. That is, the seating part should just be a thing which can be folded up. In this case, when the seating portion is rotated between the left and right feet of the cared person, the width in the left-right direction is narrowed as in this embodiment so as not to contact the foot of the cared person. It is desirable to be configured to be foldable.

  Moreover, the structure of the rotation support part which concerns on this invention is not restricted to the structure of the rotation support part 30 which concerns on this embodiment. That is, the rotation support portion may be any one as long as the seat portion 20 is rotatably supported.

  Moreover, the rotation control part which concerns on this invention is not restricted to the notch part 12b which concerns on this embodiment. That is, the rotation restricting portion may be any member capable of restricting (fixing) the rotation of the seating portion 20. For example, the rotation restricting portion may be configured using a member different from the carriage 10 (supporting portion 12). Is also possible.

  Further, the upper body holding portion according to the present invention is not limited to the upper body holding portion 60 according to the present embodiment. That is, the upper body holding portion may be any one as long as it holds the upper body of the care recipient and is rotatable with respect to the cart portion 10.

  In addition, the upper body holding portion 60 may be configured to be rotated using an actuator (for example, an electric motor, an electric cylinder, or the like). By this, the waist of the care recipient can be easily floated, and the work burden on the assistant can be reduced.

  It is also possible to provide a mechanism (lifting and lowering mechanism) capable of changing the vertical position of the seat unit 20, the foot support unit 40, the knee support unit 50, and the upper body holding unit 60. By this, the height of the seating portion 20 and the like can be adjusted to the physical size of the care recipient and the place before and after transfer (height of the toilet bowl, bed, etc.), and transfer operation can be performed more easily.

  Also, although the foot support portion 40 and the knee support portion 50 are configured to simply support (receive) the feet and knees of the care recipient P, it is possible to fix the feet and knees of the care recipient P with a belt or the like. A possible configuration is also possible.
