Ski training apparatus
First Claim
1. A ski training apparatus comprising:
- a pair of left and right footboards on which a trainee stands instead of skis;
a movable portion which supports said footboards to allow said footboards to rotate clockwise and counterclockwise, and swings to displace said footboards along an arcuated locus in accordance with ski-sliding movement of the trainee;
an apparatus body which supports said movable portion to allow said movable portion to swing in a horizontal direction;
measuring means for measuring loads of the left and right feet of the trainee standing on said footboards, and outputting the measured loads as load information, while measuring a displacement amount of said movable portion and rotational angles of said footboards, and outputting the measured amount and angles as displacement information;
movement estimating means for estimating a sliding velocity, a position of the trainee on a slope, and an edging strength representing a magnitude of a reactive force received from a snowy surface and corresponding to a load of the trainee on the snowy surface on the basis of the load information and the displacement information, which are supplied from said measuring means, and geographical information input in advance and indicating a state of the inclined surface on which the trainee slides, and outputting the estimated sliding velocity, position, and edging strength as movement information; and
braking control means for calculating a braking amount by using the load information and the displacement information which are supplied from said measuring means and the movement information which is supplied from said movement estimating means, and outputting the braking amount as braking information; and
braking means for applying a braking force to said movable portion in accordance with the braking information from said braking control means.

Abstract
A ski training apparatus includes footboards a movable portion, an apparatus body, a braking section, a movement estimating section, a braking control section, and a braking section. The movable portion supports the footboards to allow them to rotate, and displaces the footboards in accordance with ski-sliding movement. The apparatus body supports the movable portion to allow it to swing. The measuring section measures the loads of the feet of a trainee on the footboards to output load information, while measuring the displacement amount of the movable portion and the rotational angles of the footboards to output displacement information. The movement estimating section estimates a sliding velocity, the position of the trainee on a slope, and an edging strength representing the magnitude of a reactive force received from a snowy surface and corresponding to the load of the trainee on the snowy surface on the basis of the load information, the displacement information, and geographical information, and outputs movement information. The braking control section calculates a braking amount from the pieces of above information to output braking information. The braking section applies a braking force to the movable portion in accordance with the braking information.
