DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiment shown in the figure is an electric wheelchair for nursing care, which is constructed as follows. One supporting rod 10 made of a pipe material from the center of the lower surface of the traveling vehicle body 3 toward the front.
And the central part of the horizontal rod 11 is welded to its tip. Vertical bosses 12, 12 are welded to both left and right ends of the horizontal rod 11, and the bosses 12, 12 rotatably hold the longitudinal axes 13, 13 of the front wheels 1, 1 having a caster angle. . Reference numeral 14 is a rotary shaft of the front wheel, and 15 is a mounting arm of the rotary shaft 14.

Reference numerals 16 and 16 denote a pair of left and right mounting brackets, the bases of which are welded at intervals near the center of the horizontal rod 11 so as to project forward, and the horizontal shaft 17 is welded and fixed to the tip thereof. Reference numerals 18 and 18 denote left and right foot-mounting steps. The rear end boss portions 19 and 19 are rotatably supported by the horizontal shaft 17, and can be switchably held between a substantially horizontal foot-mounting position and a standing storage position. Is configured. A drive control member (not shown) such as a motor, a battery, a control box, and a gear box is mounted on the traveling vehicle body 3 so that the rear wheels 2 and 2 can be driven, and the entire body is covered by the cover 20. There is.

The support member 2 of the chair 5 has its frame portion 22 protruding upward from the traveling vehicle body 3 through the cover 20.
It is attached and fixed to the upper end of 1, and is composed of a seat plate 23, a backrest 24, and armrests 4 and 4 on both sides. Reference numeral 25 denotes a support frame for the armrest 4, which is constructed by bending a pipe material in a U-shape in a side view, and the lower portion thereof is a frame portion 22 of the chair 5.
It is stuck to. An inverted U-shaped knee support frame 26 is deeply inserted into the opening end of the pipe material at the front end of the U-shaped support frame 25, and the protruding amount thereof can be adjusted and can be fixed by a bolt 27. I am doing it. Reference numeral 28 is an elastic knee pad.

On the upper portions of the left and right support frames 25, armrests 4,
4 is attached to the armrest 4, and a concave portion 7 having a predetermined depth is formed in the longitudinal direction on the upper surface of the front portion of the armrest 4, and a pivotally supporting portion 8 is provided at the front portion of the armrest 4 and the pivotally supporting portion 8 is provided. A front end of a grip 9 for holding a cared person is rotatably held, and a posture in which the grip 9 stands up and protrudes upward from a front portion of the armrest 4 and the armrest 4
It can be switched to a posture in which the recess 7 is fitted and stored. An L-shaped fixture 29 is attached to the rear of the frame portion 22 of the chair 5 with bolts, and a pair of left and right handles 6, 6 are inserted into support pipes 30, 30 which are welded and fixed to the fixture 29. By adjusting the insertion depth, the heights of the handles 6 and 6 can be adjusted.

Reference numeral 32 is a knob bolt for fixing the handles 6, 6. The handles 6 are provided along the back of the chair 4 and are bent and extended obliquely upward and rearward from the middle of the handle.
In addition, the rear end is bent inward and the grips 33, 33 are bent.
Is configured. Reference numeral 34 denotes a connecting rod, which connects the left and right handles 6 and 6 and has an operation box 35 attached thereto. The operation box 35 is provided with an accelerator lever 40 together with a key switch 36, a forward / backward changeover switch 37, a speed change switch 38, a battery meter 39, and the like so that an electric wheelchair for care can be operated.
