(under subclass 166) Device wherein at least one such pair of binding surfaces is configured to provide positive interengagement.
(1) Note. Patent placement here requires both surface modification and canting to maintain said surfaces together.
(2) Note. The term "configured" includes: "teeth", "roughened", "racks", "serrations", etc., as integral surface characteristics, thus "positive interengagement" also includes any surface modification which enhances frictional binding.
(3) Note. In the illustration shown below A indicates the adjustable position of the jaw member 2 while B indicates the lock position. [figure]
