  The object of the present invention is to eliminate the disadvantages of the conventional wheelchair.

  The wheelchair of the present invention has a seat that can be split into two, a back surface and a bottom surface of the lower portion of the seat, a gap into which a disabled person moving bed can be inserted into the lower surface of the seat, a vehicle body having both side walls, and the two Each of the seat opening / closing drive means for opening and closing each of the seats that can be freely separated and moved in the direction of contact with each other, the holding plate of the seat opening / closing drive means provided on each of the side walls, and a wheel. And a brake driving means, a seat opening / closing driving means, and a synchronous driving means for driving the brake operating means in synchronism with each other.

  In the wheelchair according to the present invention, the seat opening / closing drive means pivotally supports the base end pivotably on the holding plate and pivotally supports one of the seats with one free end divided into two in the horizontal plane. The first and second L-shaped links that are spaced apart and extend in parallel, and an operating rod that pivotally supports the other free end of the first and second L-shaped links. The first and second L-shaped links are rotated approximately 90 ° synchronously in the horizontal plane, and the two split seats are moved away from and in contact with each other in the horizontal plane. And an L-shaped lever pivotally supported on the side wall of the vehicle body and a brake attached to one free end of the L-shaped lever. A synchronous drive lever which is pivotally supported and freely displaceable along a guide formed on the side wall; A seat opening / closing cable for connecting between the synchronous driving lever and the operating lever of the seat opening / closing means, and a brake operating tensile cable for connecting between the synchronous driving lever and the other free end of the L-shaped lever of the brake operating means. When the synchronous drive lever is displaced, the seat is opened and a brake is applied to the wheel.

  According to the wheelchair of the present invention, by operating the synchronous drive means, the seat in the vehicle is divided into two very easily and easily, and each is moved to the left and right sides of the vehicle body so as to be opened and closed. It is easy to move and at the same time brakes are applied to the wheels, which is extremely safe.

A gap 8, a disabled space 8 formed in the upper front of the vehicle body 2, an opening / closing drive means 9 for the seat 5, and a holding plate having one end fixed to the vehicle body 2 for holding the opening / closing drive means 9. 10, the brake 11 of the front wheel 3, the operating means 12 of the brake 11, the opening / closing driving means 9 of the seat and the synchronous driving means 13 that drives the operating means 12 of the brake synchronously. .

  The vehicle body 2 is provided with, for example, wall plates 14 on both sides and a floor plate 15 that connects lower front portions of the wall plates 14 on both sides.

  The front wheels 3 are driven by, for example, battery-driven wheel motors (not shown) fixed at positions corresponding to the front wheels 3 of the wall plates 14 on both sides.

  As shown in FIGS. 3 and 4, the opening / closing drive means 9 of the seat 5 is pivotally supported by the base plate so as to be pivotable on the holding plate 10, and one free end of each seat 5 is divided into two. The first and second L-shaped links 16 and 17 that are pivotally supported on one of the five and spaced apart from each other, and the other free ends of the first and second L-shaped links 16 and 17 are connected to each other. A common operating rod 18 that is pivotally supported and a spring 19 that suppresses horizontal movement of the working rod 18 are configured, and this operating rod 18 is moved to the left in FIGS. 3 and 4 via a seat opening / closing cable 20. When moved, the first and second L-shaped links 16 and 17 at the positions shown in FIG. 5 are rotated in synchronization with each other by about 90 ° clockwise around the respective base ends, thereby Is moved outward from the side of the vehicle body 2 to change from the closed state to the open state.

  The same thing as the said movement opening / closing means 9 is provided also about the other of the seat 5 divided into two.

  As shown in FIG. 4, the actuating means 12 of the brake 11 according to the present invention is pivotally supported on the side wall 14 of the vehicle body 2 so as to be pivotable, and the brake 11 is provided at one end so as to face the front wheel 3. 4, an L-shaped lever 23 is connected to the other end of the brake operating cable 22 via a spring 21. When the brake operating cable 22 is pulled, the L-shaped lever 23 is centered on its base end in FIG. 4. As shown in FIG. 6, the brake 11 is brought into contact with the front wheel 3 so that the brake can be applied thereto.

  As shown in FIGS. 2 and 4, the synchronous drive means 13 in the present invention pivotally supports the lower end of the lower side of the side wall 14 and is provided with a manual opening / closing lever 24 at the upper end. An actuating rod 26 guided by the arcuate guide groove 25, a connecting portion 27 between the operating rod 26 and the seat opening / closing cable 20, and the brake provided at the lower portion of the actuating rod 26.
