Introduction:

Here we have designed a structure which makes the bicycle pumping process easier and faster. By fixing the piston rod and moving the cylinder we have converted the rotational motion into a to and fro motion. The cylinder rod is fixed in a metal base and piston is rotated by a rotating handle. Our set up has made the pumping process simpler, easier and faster. Even a child, physically handicapped person can operate this easily. The balloon pumping process is going to quicker and easier. It requires no electricity as it is purely hand driven.

Materials required:

1. Bi-cycle pump
2. Bearing
3. Iron frame

Working:

The bicycle pump is used to compress air. The air in the cylinder is compressed and pushed down in to the tube through a hose pipe. The valve in the tube of cycle prevents reversing of air flow. When the handle is pulled up again, the valve shuts off automatically. So, air cannot escape from the cycle tube, and new air is forced back into the cylinder. This process is repeated until the desired pressure is achieved. Our set up is designed in such a way that it can transform rotational motion in to simple harmonic motion. The ball and bearing arrangement reduces the developed friction. This can be used to pressure football and balloon also.

Advantages:

1. Our set up has made this process simpler, easier and faster. Even children, physically handicapped persons can operate this.
2. By using this, balloon pumping process will be quicker and easier.
3. It requires no electricity as it is purely hand driven.
