ABSTRACT:
For taking up less space when not in use, a ski is designed with a folded joint between its ends. For locking the front and back parts of the ski in the in-line condition ready for use, it is possible to have a top part acting as a splint which is bolted, for example, to the inner ends of the two ski parts, possibly between two heel-pieces on top of the ski parts. As a further possible design, the system for locking the ski parts in the in-line position, two links with a toggle function may be used or the top face of the two ski parts may have a female guide into which the top part is slipped. As a further possible locking system, the two ends of the ski parts nearest each other are designed with a hollow into which a locking core-piece with side headers acting as teeth is placed and which is kept in position by a metal cover plate on top of it. In a further design as part of the present invention, a toggle lever and a chain link are present on the top face of the ski at the position where its two halves are joined together. One end of the chain link furthest from the lever is slipped over a hook and then the lever is pushed downwards pulling tight the chain link and making certain of a stiff overall ski structure.
