  • Patent number: 4092787
    Abstract: Apparatus for teaching the technique of turning a ski comprising two plates, simulating skis, disposed in parallel, adjacent relation, each plate being provided with an assembly for secure support of a shoe thereon in that capability of sliding. Each plate is resiliently supported for undergoing two modes of movement, one mode being a raising and lowering movement responsive to weighting and unweighting the plate, the other mode being a pivotal movement of the plate about its longitudinal axis when the plate is lowered. The plates are associated with electrical switches in an electrical circuit having illuminating or other indicator devices for producing signals when the plates are properly weighted and unweighted and correspondingly pivoted around their longitudinal axes to simulate the conditions for executing a turn of the skis.
