ABSTRACT:
A multi-portion ski fitted together with numerous shaped two-part metal coupling devices one part, usually forward, has two or more threaded metal ferrels protruding upward into which metal screws are fastened. The bottom plate on the connection portion slips over the ferrels forming a tight fit. The top plate, of about one half the size, adjustably locks the bottom plate into place by interacting with slots in the sides of the ferrels. An adjustable screw controls the tension of the locking portion of the coupling device which should always tightly lock the portions together without deformation of parts.
