상기 도면에 도시된 바와 같이 본 발명은 일측에 제1 로울러(40)룰 구비한 중심축 지지대(20)를 일단은 휠체어의 후륜 중심축(14)에 끼워 조립하고 타단은 휠체어 몸체 손잡이(13) 일측에 고정 조립한다. 작동 손잡이(30)의 일단을 상기 휠체어의 후륜 중심축(14)에 끼워 회동 가능하게 조립하며, 제2 로울러(70)를 일단에 구비한 제2 로울러 지지대(60)의 일단 역시 상기 휠체어의 후륜 중심축(14)에 끼워 회동 가능하게 조립한다. 상기 제2 로울러 지지대(60)의 일측을 힌지로 회동 가능하게 일단에 클램프(100)를 구비한 클램프 지지대(90)를 구비하였다.As shown in the figure, the present invention assembles the central shaft support 20 provided with the first roller 40 on one side of the wheel by fitting it to the rear wheel central shaft 14 of the wheelchair and the other end of the wheelchair body handle 13. Fix it on one side. One end of the operation handle 30 is pivotally assembled to the rear wheel central shaft 14 of the wheelchair, and one end of the second roller support 60 having the second roller 70 at one end thereof is also the rear wheel of the wheelchair. It is fitted to the center shaft 14 so that rotation is possible. One side of the second roller support 60 was provided with a clamp support 90 having a clamp 100 at one end to be rotatable with a hinge.

한편, 상기 중심축 지지대(20)의 일측을 힌지로 하여 회동하며 휠체어의 핸들(12)의 후진 시 가압 가능하도록 클램프(100)의 전측이 휠체어의 핸들(12)에 접하도록 경사지게 구비한다. 또한, 상기 클램프 지지대(90)의 일단을 힌지로 회동가능하게 클램프(100)를 구비한다. 상기 작동 손잡이(30)의 일측에 고정되며 상기 제1 로울러(40)를 접하고 상기 제2 로울러(70)를 반바퀴를 감으며 상기 중심축 지지대(20)에 고정되도록 제1 와이어(50)가 설치된다.Meanwhile, the front side of the clamp 100 is inclined to contact the handle 12 of the wheelchair so as to rotate by using one side of the central shaft support 20 as a hinge and to be pressurized when the handle 12 of the wheelchair is moved backward. In addition, one end of the clamp support 90 is provided with a clamp 100 to be rotatable by the hinge. The first wire 50 is fixed to one side of the operation handle 30 to be in contact with the first roller 40, to wind the second roller 70 half a turn, and to be fixed to the central shaft support 20. Is installed.

또한, 상기 클램프 지지대(90)에 구비된 클램프(100)의 후측에 고정되고 상기 클램프 지지대(90)의 일단에 고정되도록 제2 와이어(200)가 설치된다. 한편, 상기 제2 로울러 지지대(60)와 클램프 지지대(90)가 회동된 후 원위치 되도록 각각의 일단에 탄성 부재(80)를 구비하였다.In addition, a second wire 200 is installed to be fixed to the rear side of the clamp 100 provided in the clamp support 90 and to one end of the clamp support 90. On the other hand, the second roller support 60 and the clamp support 90 is provided with an elastic member 80 at each end so that the original position after the rotation.

본 발명의 양호한 실시예로서, 휠체어의 조력 장치를 구성하는 상기 제1 로울러와 제2 로울러 및 상기 제2 로울러 지지대는 복수개로 구성되어 2겹, 3겹 또는 그 이상의 도르래 장치를 구성될 수 있다.In a preferred embodiment of the present invention, the first roller, the second roller and the second roller support constituting the assisting device of the wheelchair may be configured in plural to constitute a two-ply, three-ply or more pulley device.

전술한 바와 같이 구성된 본 발명은 사용자가 경사면을 오르고자 할 때 작동 손잡이를 앞으로 밀면 작동 손잡이에 의해 고정된 제1 와이어(50)에 의하여 제2 로울러(70)가 같은 방향으로 이동하면서 제2 로울러 지지대(60)가 회동하게 되며 동시에 제2 와이어(200)에 의해 고정된 클램프가 회동하며 휠체어 핸들에 접촉하게 되고 클램프 지지대가 회동되어 상기 클램프가 휠체어 핸들을 가압하면서 회동되어 상기 휠체어 핸들은 회전을 하게 된다.According to the present invention configured as described above, when the user pushes the operating handle forward when the user wants to climb the inclined surface, the second roller 70 moves in the same direction by the first wire 50 fixed by the operating handle and the second roller. The support 60 rotates and at the same time the clamp fixed by the second wire 200 rotates and contacts the wheelchair handle, and the clamp support rotates so that the clamp rotates while pressing the wheelchair handle so that the wheelchair handle rotates. Done.

소정 거리 만큼 횔체어 핸들이 회동된 후 제2 로울러 지지대(60)와 클램프 지지대(90)의 일단에 구비된 탄성 부재에 의해 상기 제2 로울러 지지대(60)와 클램프 지지대(90)가 원위치 되어 지면서 작동 손잡이도 제1 와이어(50)에 의해 원위치 되어진다.After the wheel chair is rotated by a predetermined distance, the second roller support 60 and the clamp support 90 are returned to their original position by an elastic member provided at one end of the second roller support 60 and the clamp support 90. The actuation handle is also retracted by the first wire 50.

본 발명에 따른 탄성 부재의 양호한 실시예로서, 스프링을 사용할 수 있다. 이 때 상기 클램프 지지대(90)에 구비된 클램프(100)와 휠체어 핸들(12)이 이격되면서 경사면에 의해 휠체어 핸들(12)이 역회전하기 시작하는데 상기 중심축 지지대(20)의 일측에 구비된 클램프(100)는 휠체어 전방을 향하여 경사지게 구비되어 있고 상기 휠체어 핸들(12)에 맞닿아 있어 상기 휠체어 핸들의 역회전시 소정 마찰력으로 인해 중심축 지지대(20)의 일측에 구비된 클램프(100)는 상기 휠체어 핸들(12)과 맞물려 회전하려하기 때문에 소정 압력에 상기 휠체어 핸들(12)에 가해져 역회전을 방지한다.As a preferred embodiment of the elastic member according to the invention, a spring can be used. At this time, while the clamp 100 provided on the clamp support 90 and the wheelchair handle 12 are spaced apart, the wheelchair handle 12 starts to rotate in reverse by an inclined surface, which is provided on one side of the central axis support 20. The clamp 100 is inclined toward the front of the wheelchair and abuts the wheelchair handle 12 so that the clamp 100 provided on one side of the central axis support 20 due to a predetermined friction force when the wheelchair handle is reversely rotated is In order to rotate in engagement with the wheelchair handle 12 is applied to the wheelchair handle 12 at a predetermined pressure to prevent reverse rotation.

이 때에, 클램프(100)를 가압하는 클램프 지지대(90)의 일단에 장착된 탄성 부재에 의하여 용수철 복원력이 작용함으로써 휠체어가 후진하여 미끄러지는 것을 방지할 수 있다. 따라서, 작동 손잡이를 앞으로 밀면 소정 길이만큼 휠체어가 전진을 하면서 후진은 되지 않고 제2 로울러가 도르래의 역할을 하여 힘이 경감되므로 적은 힘으로 경사면을 쉽게 오를 수가 있다.At this time, the spring restoring force acts by the elastic member attached to one end of the clamp support 90 which presses the clamp 100, thereby preventing the wheelchair from sliding backwards. Accordingly, when the operation handle is pushed forward, the wheelchair moves forward as much as a predetermined length, and the second roller acts as a pulley and the force is reduced, so that the slope can be easily climbed with a small force.
