Abstract
Abstract A steel cable is stretched overhead between a starting platform and a terminal tower and equipped with a passenger pulley having a handle from which a child can hang while rolling along the cable. Only difficultly negotiable ladder means e.g., a chain or tire ladder, are provided for climbing to the starting platform to limit access to the starting platform to children having motor skills that are sufficiently developed to ensure safe use of the cable slide. An impact cushion may be mounted upon the terminal tower below the cable. Auxiliary recreational facilities are provided in the same structures to entertain children awaiting their turns and those who are interested observers.
