Abstract
A layer of low density elastomeric material is interposed between upper and lower segments of a ski, the layer and upper segment extending along at least 35% of the length of the lower segment. The elastomeric layer contains at least one insert of high density material disposed in a direction across the width of the ski, the insert being of greater density than the low density elastomeric material to provide torsional rigidity to a ski which otherwise has softened longitudinal flexibility and enhanced vibration damping.
Claims26
A ski construction comprising:
- a lower elongated ski segment having a width defined by spaced side edges extending between opposite ends of the lower segment;
- an upper elongated ski segment overlying said lower segment, said upper segment having a width substantially corresponding to the width of the lower segment and terminating at ends located between the ends of the lower segment;
- and
- an elongated layer of elastomeric material having a width substantially corresponding to the width of the lower and upper segments, said layer being attached to and separating said lower and upper segments and extending along at least 35% of the length of the lower segment, said layer including at least one insert of material disposed within said layer in spaced relationship from opposite ends of the layer, said insert extending across the width of the layer to side edges thereof, said insert being of greater density than said elastomeric layer so as to be substantially non-resilient thereby providing torsional rigidity between the upper and lower ski segments.
