The attached design is intended for use on door-knobs and spherical or cylindrical tap heads of 50-
74mm diameter (standard door-knob sizes range from 60.3mm to 69.9mm). This is demonstrated in
the attached renders and below.
This design was created as there seem to be a wide range of solutions in place (or even proposed in
the competition already) for modern cylindrical door handles and slightly more modern tap designs.
This design aims to provide a solution for 'traditional' door-knob and tap designs while maintaining
usability for both able bodied and disabled, less-than-able and elderly demographics.
