The Edge Rotary Cycle Pump by Guz Bristow from uk

The Edge rotary cycle pump exploits the mechanical advantages of an innovative patented mechanical device that converts a single rotary action into multiple linear movements.

The edge will form part a range of rotary cycle pumps with a number of innovative features:- large pumped volume giving quicker inflation times, better ergonomics making tyre inflation easier with less chance of breaking valve stems, and a focus on design with the use of high end materials, making the pump a desirable object to own.

The technology at the centre of the device are multiples of small injection moulded discs which can be manufactured economically and in bulk. The other components will be high impact plastic and CNC manufactured. Packaging will be minimal with a high usage of recycled materials.
The Edge is a compact and gyratory driven pump. The rotary mechanism works by rotating a crank on the end of the pump and one turn of the pump will pump 2‐4 volumes of air in comparison with common cycle pumps. Thus the pump will inflate a tyre quicker than existing types. It is proving to be easier with the body prototypes to ergonomically rotate the crank on the rotary pump rather than the in and out motion of the standard pump. Furthermore, it will be possible to make the pumps far smaller than existing types on the market.

This pump design then offers a more efficient pump which is easier to carry. For most cyclists, these are matters of key importance. Cyclists prefer cycling to mending punctures, so any time that can be saved on this chore is beneficial. Also cyclists are would like to have an easy to carry pump‐ one that can easily fit into a pocket in a cycle jersey. One further differentiator is the design of the pump with most cycle pumps on the market being of a standard design, with little innovation happening in the market. The Edge design is innovative, eye catching, and will stand out from other designs.
