The CRC is protected
by US patent number 6,269,749 (European Community patents applied
for) , and can be downloaded here as a PDF or viewed at the United States
Patent and Trademark Office website: The USPTO. The CRC concept as described in the patent is widely
ambitious, employing
a single support arm, and so differs from what is shown in the
rendering on this site. Despite
this difference, the mechanical principles remain the same, the
result shown here being as equally exciting, but more readily constructed.
In the near future
we will be adding further examples of the CRC in other inspiring,
themed and mechanical variations.
