  • Water sliders with turning toboggans
    Patent number: 4984783
    Abstract: The present invention provides a water slider used with a round or substantially round tobogganing boat designed to be displaced into contact with one side of a slide lane in the course of toboganning. A side wall of the slide lane comes into contact with the boat and has a nearly vertical portion brought in contact with a side or side edge of the boat, thereby increasing the friction between the side wall and the boat to substantially or completely eliminate any relative slippage therebetween. The slide lane may be provided on one side with a slight dent.
