Next, an upper attachment mechanism A and a lower attachment mechanism provided at the free end of the cantilever 5 described above.
A specific ellipse of B will be described in detail with reference to FIGS. 9 to 16. First, the upper attachment mechanism A will be described. The armpit support portion 8 is adjustably attached to the outer end portion of a bending bar 8A formed by bending the inner and outer end portions at 90 degrees and bending at right angles. That is, as shown in particular in an enlarged view in FIGS. 12 to 14, a male screw 8B and an axially long groove 8C are provided at the outer end of the bending bar 8A, and the male screw 8B is provided on the adjusting ring 8D. While being screwed into the screw hole 8E, a detent 8G protruding in a radial direction from the long hole 8F of the side support portion 8 is fitted in the long groove 8C.

The mounting ring 8J is screwed to the side support portion 8 and the mounting ring 8H is also screwed to the mounting ring 8J. On the other hand, the mounting ring 8I is fixed to the adjustment ring 8D by bolts 8K, but FIG.
As shown in FIG. 5, the end of the mounting ring 8I on the side of the side support portion protrudes radially inward in the shape of a collar, and since the inner diameter is smaller than the outer diameter of the mounting ring 8H, the mounting ring 8I can be mounted even if it rotates. It does not come off from the ring 8H. After all, when the adjustment ring 8D is rotated, the side support portion 8 slides in the axial direction of the bending bar 8A. by the way,
This adjustment is made according to the physique of the cared person. B is a bellows, one end of which is fitted into the bending bar 8A and the other end of which is fixed to the adjusting ring 8D.
It is intended to prevent the exposure of the person and not to give discomfort to the care recipient.

The inner end of the bending bar 8A has a casing 22.
It is inserted into the lateral hole 26 of the circular gear supporting member 25 attached to the pivot shaft 24 provided upright on the bottom surface 23, and is rotatably fitted and connected to the joint 27 pinned. The coupling relationship between the inner end of the bending bar 8A and the joint 27 is as shown in FIGS.
Through the circular arc hole 8L at the inner end of the
Is screwed into. Since the circular arc hole 8L is machined in the inner end portion of the bending bar 8A over a range of about 40 degrees in the circumferential direction, the bending bar 8A can rotate about the axis of the joint 27 within a range of about 40 degrees. Is.

The rack member 29 having rack teeth 29A, 29A meshing with the circular arc gears 25A, 25A of the member 25 is slidably supported by a guide rod 30. The guide rod 30 is placed on a stand 31 which is installed on the bottom surface 23 of the casing 22, and is slidably fitted into a sleeve 32 having spur teeth 32A engraved on the upper surface thereof, and the rack member 29 and the sleeve. A compression spring 33 is wound between 32. Also,

0B is provided.

A partition plate 34 is provided in the middle of the casing 22, one end is pivotally supported by a support member 35 provided at the center of the partition plate 34, and the flat teeth of the sleeve 32 are located below the other end. A lever 37 for pivotally supporting a locking tooth 36 that meshes with 32A is provided on the partition plate 34 via a spring 38, and a pusher 39 of the lever 37 is laterally provided inside the casing 22 at the other upper end. It is pivotally supported by an axis.

Therefore, when the cared person is transferred from the bed to the lift, the pusher 39 is moved to the dotted line position, and after the transfer, the pusher 39 is moved to the solid line position so that the locking teeth 36 are attached to the spur teeth 32A. The side support parts 8 and 8 can be prevented from expanding by being meshed with each other, but since the spring 33 wound around the guide rod 30 is compressible, the side support parts 8 and 8 are narrowed inside, that is, narrowed. It is possible to move in any direction. That is, when the side support parts 8 and 8 are applied to both sides of the care receiver and the back support band 9 is attached in a tensioned state on the back side, when the back of the care receiver is leaned on the back support band 9, Since both support parts 8 and 8 try to move inward, both sides of the care receiver are lightly tightened, and a stable support state is obtained. In other words, when the mother holds up the baby, it has the same function as not only simply raising the armpits, but also lightly tightening the armpits from the left and right to firmly support the upper body.

Also, the upper attachment mechanism when stored
It is necessary to move A to the column 2 side and the lower attachment mechanism B to the opposite side, but in this case, the bending bar 8A can rotate about the axis of the joint 27 within the range of 40 degrees as described above. Therefore, the bending bar 8A is attached to the cantilever 5.
You can raise it temporarily so that it doesn't hit you. At this time, the support rod 41 (described later) is attached to the support column 2 together with the calf-carrying portion 12.
It can be made more compact by sliding it to the side.

Then, the back support band 9 is doubled with a commercially available latch type band in consideration of safety.
Further, the handrail portion 10 is formed of an arcuate tubular body, and is attached above the back portion of the casing 22.

Next, regarding the lower attachment mechanism B ,
Hereinafter, a detailed description will be given. A vertical hole 5B is formed in the free end portion 5A of the cantilever 5, and a connecting rod 40 having its upper end fixed to the bottom surface 23 of the casing 22 is rotatably inserted into the vertical hole 5B. The thigh carrier 11 is attached to the lower end flange 40A of the connecting rod 40 with bolts or the like. The thigh carrier 11 includes upper and lower members 11A and 11A that form a square hole H in the horizontal direction.
B, 11C, 11D and a ball-latch type pin shaft 1 that can be swung in the front-back direction outside the both side members 11C, 11D.
The outer members 11F and 11F pivotally supported by 1E, and the substantially U-shape pivotally supported by the lower ends of the outer members 11F and 11F so that they can be opened and closed laterally by 45 to 60 degrees and can be appropriately locked by a pin or the like in the open and closed position. -Shaped thigh rest portion 11G, 11
It consists of G. Note that, as shown in FIG. 18, it is desirable that the thigh rest portion 11G support almost the middle part of the thigh.

A support rod 41 having an H-shaped cross section having retaining portions at both ends is slidably fitted in the square hole H. The calf-carrying portion 12 is further mounted on the support rod 41. That is, the calf-carrying portion 12 is a gate-shaped member 12A mounted on the support rod 41.
And 45 degrees to 60 in the lateral direction at both lower ends of the gate-shaped member 12A.
A substantially U-shaped calf rest 12B, 12B pivotally supported so that it can be opened and closed once and can be locked appropriately in the open and closed position.
It consists of

The vertical movement of the cantilever 5 is performed by pressing either the upward movement button or the downward movement button (not shown) of the operation panel 6. That is, referring to FIG. 17, when the upward movement button of the operation panel 6 is pressed, the motor 42 rotates in the normal direction, and the pulley 43 at the lower end moves from the belt 4 to the belt 4.
The pulley 46 at the lower end of the screw spline 45 in the support column 2 is driven via 4 and as a result, the ball nut 47 screwed to the screw spline 45 moves up, and the cantilever 5 integrated with the ball nut 47 also moves up. Then, when you release the up button, the motor 42 immediately
Stops, and the rise of the cantilever 5 also stops. On the other hand, if the down button is pressed, the motor 42 reverses, and as a result, the cantilever 5 moves down, and if the hand is released from the down button,
The lowering of the cantilever 5 also stops immediately. In this embodiment, the upper limit of the cantilever 5 is 1070 m from the floor surface.
m, and the lower limit was 370 mm from the floor. Therefore, since the cantilever 5 can be accurately stopped at an arbitrary position within the range from near the floor to above the bed by operating the button on the operation panel 6, the care recipient lying on the bed or the floor for rehabilitation can be easily transferred. Can be made.

By the way, the upper and lower attachment mechanisms
A and B can be rotated about a connecting shaft 40 integrally formed with them, but the free end portion 5 of the cantilever 5 is
It is also possible to lock at four rotational positions by the four holes 5C formed at the upper edge of A at intervals of 90 degrees and the plunger 23B supported by the stay 23A below the bottom surface 23 of the casing 22. Therefore, as shown in FIG. 19 to FIG. 22, there is a position (FIG. 19) which can be dealt with when the cared person on the bed or the floor has his head on the left side (when viewed from the side of the column 2), on the bed, or on the bed. Position that can be dealt with when the cared person on the floor is head to the right (Fig. 20), position when moving to a wheelchair or toilet bowl (Fig. 21) when separated from the bed or floor, and storage form (Fig. 22)
And so on.

Further, the transfer operation of the cared person by the lift will be described below with reference to FIGS. 23 to 32.
