发明名称 Ski training mirror method and apparatus
摘要 A mirrored training device for attachment to a ridden board-type athletic device is disclosed. The training device comprises a convex mirror in a shockproof case having attachment means for securing the training device to the board surface. The mirror casing may be angled, or unequal length legs may be provided, so that the attached convex mirror is inclined towards the rider's normal board riding position to provide a full reflection thereof. Dividing lines are provided on the mirror surface as reference points for the posture of the athlete. In an alternative embodiment the mirrored device is built into the ridden-board-type device.
