본 발명은 흙받이와 지지대 일체형 모터브라켓이 구비된 휠체어동력보조장치와 휠체어의 연결구조에 관한 것으로, 보다 상세하게는 휠체어동력보조장치에 흙받이와 지지대 기능을 가진 일체형 모터브라켓을 구비하며, 휠체어의 프레임에 결합된 브라켓결합체와 휠체어동력보조장치에 결합된 체결봉결합체에 의하여 휠체어와 휠체어동력보조장치의 결합 및 분리를 손쉽게하면서 지속적으로 견고함을 유지하는 것에 관한 것이다. The present invention relates to a connection structure between a wheelchair power assist device having a fender and support integrated motor bracket and a wheelchair, and more particularly, a wheelchair power assist device having an integrated motor bracket having a fender and support function, and a wheelchair It relates to continuously maintaining robustness while facilitating coupling and separation between a wheelchair and a wheelchair power assist device by a bracket combination body coupled to a frame and a fastening bar combination body coupled to a wheelchair power assist device.

일반적으로, 휠체어는 다리가 자유롭지 못한 사람이나 보행에 불편한 노약자가 앉은 상태에서 장소를 이동할 수 있게 하는 보행 보조기구이다. 휠체어는 구동방법에 따라 이용자가 손으로 바퀴를 구동시키는 수동휠체어와, 전동기에 의하여 휠체어 전체를 구동시키는 전동휠체어로 구분된다. 수동휠체어는 이용자가 직접 손으로 바퀴를 구동시켜야 하므로 장거리 운행이 어려울뿐만 아니라 경사도 운행시에는 직접 힘을 가하여 수동휠체어를 구동해야 하기 때문에 불편한 점이 있는 반면, 전동휠체어는 전동기를 통해 바퀴를 구동시킴으로써 단거리 이동시에는 이용자에게 편리한 점은 있으나, 장거리로 이동할 경우 어쩔수 없이 전동휠체어를 차내로 운반해야 하기 때문에 전동휠체어가 공간을 많이 차지할 뿐만 아니라 차내로 수용되지 못하는 경우도 있다. BACKGROUND ART In general, a wheelchair is a walking aid that enables a person with inflexible legs or an elderly person who is inconvenient to walk to move from place to place while sitting. Wheelchairs are divided into manual wheelchairs, in which the user drives the wheels by hand, and electric wheelchairs, in which the entire wheelchair is driven by an electric motor, according to the driving method. Manual wheelchairs are not only difficult to drive long distances because users have to drive the wheels by hand, but also have inconveniences when driving on an incline because they have to apply force directly to drive the manual wheelchairs. It is convenient for the user when moving, but when moving long distances, the electric wheelchair must be transported inside the car, so the electric wheelchair takes up a lot of space and sometimes cannot be accommodated inside the car.

이러한 문제점을 해결하기 위하여 본 출원인은 대한민국 등록특허 제1697761호인 '휠체어와 구동장치의 결합구조'를 등록받았으며, 이어서 상기 선출원을 개선한 특허등록 제1687187호인 '각도 및 폭 조절이 가능한 휠체어 프레임 연결장치'를 등록받은 바 있는데, 상기 선특허는 연결장치의 연결로드에 장착된 연결클램프를 조작하여 휠체어 전방의 프레임에 휠체어동력보조장치를 고정시키는 것으로, 연결클램프는 회전식의 조절레버를 구비하여 조작하고 연결클램프 내측에 스프링을 장착하여 탄성력에 의해 조작할 수도 있고, 프레임의 각도가 다르게 제작된 휠체어에 연결장치를 결합하여 사용할 수 있으며, 휠체어의 프레임에 결합된 연결클램프의 결합력을 해제하여 연결장치와 휠체어를 서로 분리시킬 수 있었다.In order to solve this problem, the present applicant registered Korean Patent No. 1697761, 'Combined structure of a wheelchair and driving device', and then Patent Registration No. 1687187, 'Wheelchair frame connection device capable of adjusting angle and width', which improved the previous application. ' has been registered, and the prior patent fixes the wheelchair power assist device to the frame in front of the wheelchair by manipulating the connecting clamp mounted on the connecting rod of the connecting device, and the connecting clamp is equipped with a rotary control lever and operated It can be operated by elastic force by installing a spring on the inside of the connecting clamp, and it can be used by combining the connecting device with a wheelchair with a different frame angle. The wheelchairs could be separated from each other.

그러나, 상기 선특허의 연결클램프는 회전식 조절레버가 구비되어 좌우회전이 가능하여 연결클램프를 휠체어의 프레임에 결합하기가 간단하였지만, 상기 결합으로 일체로 형성된 휠체어와 휠체어동력보조장치가 장기간 사용함에 있어서 연결클램프와 휠체어의 프레임 간에 반복되으로 가해지는 외력에 의한 회전모메트 발생과 피로도 증가로 인하여 프레임과 연결클램프의 결합이 점점 헐거워지거나 손상되는 경향이 발생한다. However, the connection clamp of the prior patent is provided with a rotary control lever and can be rotated left and right, so it is easy to couple the connection clamp to the frame of the wheelchair. The coupling between the frame and the connecting clamp tends to be gradually loosened or damaged due to the generation of rotational moment due to the external force repeatedly applied between the connecting clamp and the frame of the wheelchair and the increase in fatigue.

또한, 휠체어동력보조장치에 흙받이를 구비하지 않아서 운행시 흙이 사용자 측으로 튀어 운행에 불편을 줄 뿐만 아니라, 휠체어동력보조장치가 자체적으로 세워질 수 있는 역할을 하는 지지대가 휠체어동력보조장치의 핸들축에 설치되어 휠체어동력보조장치에서 가해지는 하중을 곧 바로 지탱하여 지지하지 않고 연결프레임에 간접 설치되어 하중을 지탱하고 있음으로 인하여 연결프레임과 지지대 간의 결합이 약화되고 장기 사용시 지지대가 뒤틀어지거나 손상되는 경우가 발생하였다. In addition, since the fender is not provided in the wheelchair power assist device, soil splashes toward the user during operation, which not only causes inconvenience in operation, but also supports the wheelchair power assist device to stand on its own. In case the coupling between the connection frame and the support is weakened and the support is twisted or damaged during long-term use due to the load being indirectly installed on the connection frame to support the load rather than directly supporting the load applied by the wheelchair power assist device. has occurred.
