ABSTRACT:
A ski stabilizing device used in combination with a pair of skis to assist a novice skier in learning to ski includes a pair of block members, each block member attached to the inner edge of one ski adjacent the inflected tip of the ski. Each block member encases a spherical region which registers with a circular aperture located on an inside face of the respective block member. Disposed within each spherical region is a ball. Extending between the block members for connecting each ball is a connecting rod which maintains the skis at a generally fixed distance from each other. The encasement of the balls within the block members allows for the independent angular, rotational and longitudinal movement of the skis with respect to each other and with respect to the ski slope on which the novice skier is skiing. The device includes the capability to gradually enlarge or reduce the amount of angular, rotational, and longitudinal movement of the skis. By selective adjustment, longitudinal and rotational movement of each ski can be gradually enlarged or reduced in conjunction with the level of skill attained by the novice skier.
