Abstract
A hinge mechanism includes a first hinge element, a second hinge element, and a locking element. The first and second hinge elements each include a plate portion and a plurality of substantially parallel fingers spaced from one another. The pluralities of substantially parallel fingers interlock with one another along a pivot axis such that the first and second hinge elements are rotatable relative to one another about the pivot axis between an extended position and a folded position. The locking element extends substantially parallel to the pivot axis and may be configured to releasably engage a receiving portion in one of the pluralities of substantially parallel fingers when the first and second hinge elements are in the extended position to lock the first and second hinge elements relative to one another. A collapsible ascension ski having such a hinge mechanism as well as related methods and kits are also disclosed.
