Reference numeral 12 denotes a set link, which is provided at the rear position of the link frame and is provided in the same manner as the link frame by plate-like links 13 and 14 which overlap each other. 14 set holes 13a, 14a
And setting holes 15a, 16 in the arms 15, 16 rotatably connected to the handle frames 3, 3.
a, and the left and right frames 1, 1 are extended to the left and right at an interval corresponding to the chair hanging width.
The left and right frames 1, 1 can be set in a stable state without expansion and contraction by connecting the holes a and holes 14a, 16a with pins 17, 18.

Reference numerals 19, 19 denote front wheels, and the chair frame 4
A vertical pipe 20 is fixed to the outer part of the front pipe 5 and the outer part of the front pipe 5, and a caster support shaft 21 is attached to the lower end of the pipe so as to be vertically adjustable , and is rotatably supported on the caster. Reference numeral 22 denotes a bracket for fixing the pipe 20 to the frame 4. Reference numeral 23 denotes a partition frame, which includes a bracket 24 fixed to the handle frame 3 and the pipe 2.
It is pivotally mounted on a pin 25 provided between the bracket 22 and the bracket 22 to which the “0” is attached.

Reference numeral 26 denotes a rolling rear wheel which can be handled and driven. A wheel support arm having a bracket 27 fixed to the handle frame 3 and a base portion rotatably mounted on the bracket 27 is provided.
A plurality of axle fixing holes 29, 29,. Further, the wheel supporting arm 28 and an arm 30 that rotates before and after pivoting to the handle frame 3 side are pivotally connected to the handle frame 3 side by an interlocking rod 31 so that the wheel supporting arm 28 is moved in the front-rear direction. Movably provided. Reference numeral 26b denotes a handle ring. In this embodiment, the upper part of the arm 30 is curved forward so as to be used as the support rod 30a of the armrest frame 32. Reference numeral 33 denotes a left-right sway-preventing projection which is fixed to the wheel support arm 28 and is provided in the hole of the perforated plate 34 fixed to the handle frame 3 so as to be insertable and removable.

A lock device 35 is provided at a tip end of a lock arm 35a rotatably mounted on the support rod 30a of the chair elbow frame 32 to the left and right sides, and a pipe frame 23a surrounding the outer periphery of the partition frame 23. Is provided with a lock claw 35b which can be disengaged. Reference numeral 37 denotes a spring 37 that is elastically held in a locking direction. Reference numeral 38 denotes a boarding chair seat, which comprises a seat receiver 39 and a boarding chair body 40 as follows.
The seat receiver 39 is made of cloth or a plurality of ropes, and the horizontal portions 4a, 4a of the left and right chair frames 4, 4 are provided.
The left and right ends are attached to the rods 41, 41 extending in the front-rear direction, which are attached to the vehicle. The boarding chair body 40 is a flexible seat.
And a side portion 40b covering the partition frame 23. The outer surface of the side portion 40b is formed in a bag shape to form the partition frame. -Are mounted so as to enclose them. Therefore, the side portion 40b can also fall outward as the partition frame 23 rotates outward.

42 is a footrest, 43 is a wheel brake, 45
Is the back of the chair. Next, the operation of the above example will be described. As shown in FIG.
The left and right frames 1 and 1 are extended right and left outward so that the chair can be hung, and the set link 12 is fixed by the arms 15 and 16. At this time, the boarding chair seat 38 is attached to the left and right rear wheels 26,2.
There is a partition frame 23 which stands between the chair rests 40a on the left and right sides of the chair hanging portion 40a, and a side portion 40b is formed on the inner surface of the frame 23.
5 is locked, and an elbow frame 32 is formed above the partition frame 23. When the frame portion is viewed from the front, it is fixed in the state shown in FIG. Therefore, the handicapped person can run independently by handling the handling ring 26b as in the case of boarding a normal wheelchair.
In addition, when the caregiver runs, the handle 7 can be moved forward and backward by pushing and pulling.

When returning to the bed 44 from this running state, the wheelchair exhibits a great effect. That is, the disabled person or a caregiver puts the wheelchair sideways on one side of the bed 44, unlocks the lock device 35 on the bed side, and moves the rear wheel 26 on the side to the rear side. That is, the rear wheel 2
6 can be freely moved rearward because it is supported by a rotatable wheel support arm 28. At this time, in the embodiment, the support rod 30a of the elbow frame 32 is formed integrally with the arm 30, and is attached to the wheel support arm 28 by the interlocking rod 31, so as shown in FIG. The chair elbow frame 32 is swung upward and rearward with the movement of 26, so that the screen frame 23 is not obstructed from rotating outward.

In this manner, the rear wheel 26 and the chair elbow frame 32 are set so as not to hinder the rotation of the partition frame 23, and the partition frame 23 is rotated toward the bed 44 as shown in FIG. The screen frame 23 is supported by the bed 44 and the bridge is formed between the wheelchair and the bed. That is, the boarding chair body 40 is provided on the upper surface of the partition frame 23.
The side part 40b is laid continuously on the chair hanging part 40a, and the disabled person S slides the side part 40b on the partition frame 23 which has been laid down as shown in FIG. You can move on.

Conversely, when transferring from the bed 44 to a wheelchair, the method described above may be reversed. In contrast to the conventional method of getting on and off from the front of the wheelchair, getting on and off from the side is extremely easy. It is very convenient and can move between the bed 44 and the wheelchair in a safe state without an attendant.

[0013]

According to the embodiments of the Invention The present invention, to be able to move the rear wheel of a large diameter located on the side of the wheelchair seat to a position that does not inhibit the outside rotation of the screen frame, the screen frame
By displacing the bridge portion on the bed side to form a bridge, the disabled person can easily move to the bed from the side of the wheelchair, or conversely, can move to the wheelchair from the bed side.
