It is composed of a pair of left and right connecting pieces 26, 26 inserted between 1b.
The holding plate 21 is located near the rear portions of the horizontal portions 1b and 1b of the main body arm 4, and the vicinity of both ends 21a of the holding plate 21 passed in the left-right direction is bent at a predetermined angle toward the front P direction. Since the pair of left and right holding arms 20 and 20 project from above both ends 21a, the tips of the holding arms 20 and 20 project in the left-right direction.
Further, the bottom surface 20a of the holding arm 20 is rotatably fastened to a point near the outer periphery of the bottom surface by the holding arm fixture 22, and is bored on the holding plate 21 in the left-right direction. It is also fastened by a guide tool 22a that moves in the guide hole 23 along the radial locus, and the holding arm 20 protruding there rotates along the hole of the guide hole 23 centering on the holding arm fixing tool 22. By moving the moving guide tool 22a, the distance between the pair of holding arms 20 and 20 can be widened or changed in the narrowing direction, and the distance between the pair of holding arms 20 and 20 located in the left-right direction can be adjusted. If the guide tool 22a is fastened, the holding arm 20 is fixed at that position.
Then, the connecting portion 25 and the one end side of the pair of left and right connecting pieces 26, 26 are connected to any of the plurality of fixing holes 25a arranged in the height direction of the main body arm 1 on the side surface of the connecting portion 25. By positioning through the positioning pin 27 passed through the connecting piece 26 and appropriately selecting the fixing hole 25a, the height position of the holding arm 20 of the upper limb holding portion 2 from the floor can be adjusted.
Further, the upper limb holding portion rotating shaft 11 is inserted at an intermediate position of the pair of left and right connecting pieces 26, 26 to the other ends, and the guide shaft 30 is further located near the other ends of the pair of left and right connecting pieces 26, 26. Is inserted.

In the case of this embodiment, the expansion / contraction mechanism 3 is composed of an electric cylinder. The electric cylinder 3 has one end 3a forming the lower end protruding from the main body arm 1 described above in the front P direction and is rotatably connected on a one-step higher surface 4a on the front side of the base portion 4. On the other hand, the other end 3b forming the upper end of the electric cylinder 3 is the main body arm 1 formed in the front P direction from the position of the upper limb holding portion rotating shaft 11 provided on the horizontal portion 1b of the main body arm 1. It is rotatably connected to a guide shaft 30 that moves along the guide hole 12. At the same time, the other end side of the pair of left and right connecting pieces 26, 26 of the upper limb holding portion 2 that is inserted between the pair of left and right horizontal portions 1b and 1b and can rotate around the upper limb holding portion rotating shaft 11 at the midpoint. The guide shaft 30 is also inserted between them, and the upper limb holding portion 2 is also connected to the other end 3b of the electric cylinder 3.
Therefore, the lifting operation and the tilting operation are continuously generated by driving only one of the electric cylinders 3, the lifting operation of the care-requiring person M can be completed, and the operation of sitting the care-requiring person M in the opposite direction is performed. This can be achieved only by driving one electric cylinder 3 in the extending direction.

That is, when the electric cylinder 3 is contracted, the guide shaft 30 descends along the arc-shaped guide hole 12, and the upper limb holding portion 2 rises accordingly, and the upper limb holding portion 2 rises at an angle of 50 °. When the guide shaft 30 reaches the lower end of the guide hole 12 and the electric cylinder 3 further contracts, the force for pulling the guide shaft 30 is transmitted to the main body arm 1, and this time, the main body arm 1 causes the main body arm 1. While being regulated by the arc-shaped guide hole 14 about the tilting central axis 10, it finally tilts to an angle of 25 ° at the upper end of the guide hole 14 and tilts in the front P direction.
When the electric cylinder 3 is extended from there, the main body arm 1 moves backward and the inclination returns, and the main body arm 1 returns to the upright state.
When the electric cylinder 3 is further extended, the force pushing the guide shaft 30 escapes through the arc-shaped guide hole 12, and no force is applied to the main body arm 1, so that the guide shaft 30 is along the guide hole 12. The cylinder moves from the lower end to the upper end, and the upper limb holding portion 2 returns to the original position in the horizontal state accordingly.
Therefore, the operation of one electric cylinder 3 causes the upper limb holding portion 2 to rotate around the upper limb holding portion rotating shaft 11 to raise (lift) or return the care recipient M to the original position, and the main body. The arm 1 is tilted about the tilting central axis 10 to tilt the care recipient M or return it to its original position.
The electric cylinder 3 can be expanded and contracted by the motor 9, and the caregiver needs to wake up the care recipient M by pressing either the button that raises the operation button of the operation panel 8 or the button that sits down. The operation of sitting the caregiver M is preferably performed.

As shown in FIG. 9, a footrest plate 5 on which the foot of the care recipient M rests is placed on the lower end of the vertical portion 1a of the main body arm 1 described above, and the mounting portion 5a is attached to the outer periphery of the vertical portion 1a of the main body arm 1. The footrest plate 5 protrudes rearward from the lower end of the main body arm 1 in a form of being fitted into the base plate 4 and fixed with bolts and arranged in the opening space 44 behind the base plate 4. 1, Fig. 2).
Further, as shown in FIGS. 9A and 9B, the footrest plate 5 is provided at a position as low as possible lower than the base portion 4 and slightly above the floor surface 9, so that the care recipient M can easily put his / her foot on it. Then, it is configured to tilt integrally with the tilting operation of the main body arm 1 (FIGS. 9C and 1).
Further, as shown in FIGS. 3 and 9, the mounting plate 16 installed at the middle position of the vertical portion 1a of the main body arm 1 has an insertion pipe 16a and abuts the knee N of the care recipient M. The knee pad portion 6 that can be held is attached to the tip of the insertion portion 6b with a pin 6a in a state in which the head can be easily swung up and down, and the other end of the insertion portion 6b is inserted into the insertion portion. After inserting into the pipe 16a and aligning the hole of the insertion pipe 16a with the target hole position provided on the insertion portion 6b, the fixture 6c is penetrated from the outer periphery of the insertion pipe 16a and hits the mounting plate 16. It is fitted in contact with the main body arm 1 and attached to the main body arm 1.
Further, a grip portion 7 that can be gripped by the care recipient M in front is installed on a mounting plate 17 installed at the tip (front) position of the vertical portion 1a of the main body arm 1.

The method of using the transfer device described above will be described.
In advance, the distance between the holding arms 20 and 20 of the upper limb holding portion 2 is adjusted to the width of the body of the user requiring long-term care M, and the vertical position of the knee pad portion 6 is also adjusted.
The transfer device in the standby state shown in FIGS. 2 and 7 is moved to the bed or wheelchair of the object in which the care recipient M is sitting. At that time, if the positioning tool 45 at the rear of the base 4 of the transfer device is brought into contact with the front surface of the bed, the transfer device is positioned so that the rear portion of the base 4 does not enter the gap under the bed of the object too much ( (See FIG. 10).
Further, as shown in FIGS. 10B and 10C, if the positioning tool 45'provided on the knee pad portion 6 is brought into contact with the front side of the toilet bowl of the object, the buttock of the care recipient M can be contacted. The position is constant with respect to the object.
Next, as shown in FIG. 9A, while the person requiring nursing care M sitting on the footrest plate 5 rests his / her foot, the grip portion 7 is made to hang the hand of the person requiring nursing care M, and the knee N is placed on the knee. The care recipient M is brought into contact with the contact portion 6 so that the upper limb K (chest) is inserted between the holding arms 20 and 20 of the upper limb holding portion 2 of the transfer device to prepare a posture for riding on the transfer device. ..

Then, when the caregiver keeps pressing the button that raises the operation panel 8 in the direction in which the electric cylinder 3 contracts, the upper limb holding portion 2 rises as shown in FIG. 9B, thereby raising the upper limb K of the care recipient M. Following the lifting operation, the tilting operation by the main body arm 1 continuously lifts the care recipient M as shown in FIG. 9C. Thus, the body (upper limb K) of the care recipient M is moved to a target place (toilet, etc.) by the transfer device in a state where the body is left in the transfer device while leaning forward. Then, the button for sitting in the extending direction of the electric cylinder 3 is pushed, and the care recipient is lowered and seated (see FIG. 9C → FIG. 9B → FIG. 9A).
In this way, since the operation is simple to be performed with only two operation buttons on the operation panel 8, easy operability has been realized for the elderly care recipient M.

The height position of the holding arm 20 of the upper limb holding portion 2 from the floor can also be adjusted by changing the insertion pin position of the connecting portion 25a of the holding plate 21 (see FIGS. 4 and 5), and the knee pad portion. 6 can be adjusted before and after protruding by swinging the head back and forth according to the angle of the knee, and then changing the hole position in the insertion part 6b and inserting a pin, and can be adjusted according to the care recipient M. (See FIGS. 3 and 4).
Further, the pair of holding arms 20 and 20 project so as to be slightly narrowed toward the back, and the upper limb K of the care recipient M is completely comfortable in combination with the holding arm 20 cushioning property and the breastplate cushion 24. In addition to being fixed, the distance between the pair of holding arms 20 and 20 can be finely adjusted (see FIGS. 5 to 7).
