Abstract
Abstract A mobile skating aid for providing support for a beginning skater includes a lower frame disposed immediately above the ground surface and having wheels or low friction discs to facilitate mobility. A U-shaped hand rail is supported by posts which extend upwardly from the lower frame. The posts are arranged to enable the height of the hand rail to be adjusted and further are capable of being collapsed easily and in a manner which permits the entire device to be stored in a substantially flat, convenient configuration.
