ABSTRACT:
An improvement for cross country ski bindings comprising apparatus for preventing lateral motion of the heel of a cross country ski boot with respect to the ski when the heel is lowered into close proximity with the surface of the ski. The apparatus may comprise 2 pivotal vertical members between which the heel of the boot fits, the vertical members being, in accordance with one aspect of the disclosure, biased apart from each other so that the heel enters freely therebetween, the weight of the skier then, applied to the heel of the boot, causing the vertical members to move closer together to grip the heel of the boot. Thus the heel is firmly held in a central location on the ski. When it is desired to raise the heel of the boot, the vertical members are biased outwardly to release the heel. In accordance with another aspect of the disclosure the vertical members are rigidly communicated with the top surface of the ski, being widely enough disposed so that the heel of the boot fits loosely therebetween. With this aspect of the disclosure lateral movement of the heel is essentially restrained and the heel may be raised from the ski without impediment thereto. The disclosed apparatus thus provide for use of cross country skis with greater efficiency and facility, especially for the novice or beginning skier. Further, the ski incorporating the present invention may be used under a variety of snow and grade conditions without manual adjustment or manual attachment and detachment of the heel to the ski.
