This is an exercising, skiing teaching and skiing simulating machine constructed for use at home, or in a ski shop or in any other place inside or outside of a building, at or away from the ski slopes. The machine has foot support surfaces on which a person stands which are suspended below horizontal axes of rotation. The foot support surfaces are suspended from arms pivotally mounted on a rotating platform which is supported in a floor-mounted frame. The pivots supporting the arms are vertical and are adjustable with relation to the axis of rotation of the platform. Stop pins are provided for limiting or locking rotation of the platform, and for limiting or locking the rotation of the arms. Elastic cords are also provided for applying biasing forces to the arms which create resistance to a person's motion. Sensors are also provided for sensing and signalling incorrect motions. The frame includes hand supports for the person's hands. The machine is useful for exercising and practicing skiing. Also for trying out ski boots and ski clothing. The upward offset position of the horizontal axes of rotation relative to the boot holes, toward the person's ankles, causes the ankles to be so engaged during exercises performed on the machine that the similarity of sensations to those of actual skiing is enhanced.
An exercising and skiing simulating machine of the type which includes a substantially horizontal rotating platform and two boot support surfaces independently rotatably suspended therefrom my horizontal front to rear axes and by vertical axes means, further comprising the improvement of:
An exercising and skiing simulating machine of the type having a floor supported frame, a substantially horizontal rotatable platform supported by the frame, vertical pivots attached to the platform, arms pivotally supported by the pivots and boot support surfaces suspended from the arms by horizontal front to rear axes further comprising the improvement of:
An exercising and skiing simulating machine comprising a frame which stands on the floor, a substantially horizontal rotatable platform, supported by the frame, vertical pivots adjustably attached to the platform, arms rotatably connected to the pivots, boot support surfaces suspended from the arms by horizontal front to rear axes and being offset below the level of the horizontal front to rear axes by a distance of more than one-half inch and less than ten inches.
An exercising and skiing simulating machine comprising a floor mounted frame supporting a substantially horizontal rotating platform and vertical pivots adjustably attached to the platform and boot support surfaces rotatably suspended by horizontal front to rear and vertical axes from the pivots with the boot support surfaces being offset downward in relation to the said horizontal front to rear axes by distances equal to approximately the vertical distance from the boot sole to the ankle joint of a person.
An exercising machine and skiing teaching machine comprising:
