M. Waseem Saleem Ansari Student, J.D.C.O.E.M, Nagpur Abstract - This paper includes the design and fabrication of lever propelled wheelchair. There are many people who are disabled due to some injuries or other drastic diseases. So there are various techniques used in the improvement of the conventional wheelchair. Researchers used the techniques like HMI, HCI and Accelerometer in the wheelchair. It improved the basic model but there are some people who cannot afford such advanced wheelchair. So in this design we are using the lever for transmitting the force to move wheelchair instead of applying the force on push rim. We are using the basic mechanisms for the movement of wheelchair. The wheelchair is designed in such a way that it requires less efforts and it is cheaper than the other advanced wheelchairs.
used for indoor works as it requires more space. So in this project the concept is used in such a way that the wheelchair can be used for indoor works as well as for the outdoor works. There are people who cannot buy the power wheelchairs for daily use. So this wheelchair will be the better option for such people.

2.1 Manual Wheelchair The manual wheelchair has good indoor maneuverability and it is easy to steer in forward direction but for turning it requires more force also it requires high initial force to move. It may cause the damage in upper body of the patient. It has the disadvantage that it cannot be used for outdoor works. These push rim propelled wheelchairs are unable to be driven on the rough surfaces like grass, rocky places, ramps and sand surfaces.
INTRODUCTION
This work includes the design of lever propelled wheelchair. In the design of lever propelled wheelchair the wheels of bicycle will be used instead of push rim. The wheels will be rotated with the help of lever which will be attached to wheels by means of chain sprocket mechanism. The main motto of this project is to give the model which will require less effort than the conventional wheelchair and it will have low cost in comparison with the advanced wheelchairs available in the market. This concept is already being used in the tricycle but the tricycle cannot be
