ABSTRACT:
An improvement for cross-country ski bindings comprising apparatus for preventing or limiting lateral motion of a cross-country ski boot with respect to the ski when the boot is lowered into close proximity with the upper surface with the ski. The apparatus may comprise two pivotal vertically upstanding members between which the ski boot fits, the upstanding members being biased apart from each other so that the boot enters freely therebetween, the weight of the skier then, applied through the sole of the boot, causing the vertical members to move closer together to grip the boot in its general central, instep, portion. Thus the boot is firmly held in a central location on the ski. When, during use of the ski, it is desired to raise the boot, the vertical members are biased outwardly to release the boot. The apparatus may also comprise a plate upon which the heel of the boot rests when the boot is in its downward position upon the upper surface of the ski, the plate being selectively positionable with respect to its longitudinal position upon the ski, so that the apparatus will accomodate ski boots of varying sizes. The apparatus, therefore provides for the use of cross-country skis with improved 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 boot to the ski.
