I have created a PDF of illustrations with brief comments called Patented sports equipment for the disabled athlete.
It is a contribution to the Sport and society: the Summer Olympics and Paralympics through the lens of social science site, a British Library-led initiative to celebrate and study the meaning of the Olympics in the runup to the 2012 Games at London.
It was fun sourcing the material. Some relate to adaptations of existing sports; some are totally new sports; while others are exercise equipment designed with disabled individuals in mind.
Here is just one of the illustrations from the PDF.
