  • Patent number: 8979096
    Abstract: A training device for inline roller skates includes a training wheel bracket, a training wheel mounted upon the bracket, and means for adjustably mounting the device upon the inline skate. The training wheel is adapted to engage upon the travel surface to compensate for any unbalance of the trainee and to enable the trainee to travel in a desired direction. The training wheel is adapted to provide a braking action to the roller wheels if the trainee loses balance or the trainee's ankle collapses. The training device serves the dual purpose of providing a means of balancing the skater as well as slowing and braking the forward movement of the skater to control and limit the speed of the skater.
