  • Patent number: 6168548
    Abstract: A portable ambulatory therapy device provides for the training or retraining of persons in developing walking skills after suffering a serious illness, injury, or other infirmity which limits their walking skills. The present device comprises a folding walkway with opposed folding hand rails along each side thereof. The hand rails are supported by a series of telescoping upright columns or posts, with the columns being pivotally secured to the walkway at their lower ends and pivotally secured to the hand rails at their upper ends. Each column includes a single locking pin which selectively locks the column in the upright position as desired, or allows the column to fold when removed. When the locking pins are removed, the walkway may be lifted at its center section to cause the two ends to fold together, along with the hand rails which fold to lie adjacent the walkway.
