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.

Claims

1. A water slider used with a round or substantially round tobogganing boat designed to be displaced into contact with one side thereof in the course of tobogganing,

said water slider comprising opposing side walls and a connecting slide surface,

a side wall of said slide lane which contacts said boat having a substantially vertical portion which contacts a side or side edge of said boat, thereby increasing the friction between said side wall and said boat to substantially or completely eliminate any relative slippage between said boat and said side wall,

said water slider including a curved portion having a slide face formed into a substantially flat plane which causes said boat to slide down in a substantially linear direction, while at the same time being displaced to one side of said water slider into contact with said side wall.

2. A water slider used with a round or substantially round tobogganing boat designed to be displaced into contact with one side thereof in the course of tobogganing,

said water slider comprising opposing side walls and a connecting slide surface,

a side wall of said slide lane which contacts said boat having a substantially vertical portion which contacts a side or side edge of said boat, thereby increasing the friction between said side wall and said boat to substantially or completely eliminate any relative slippage between said boat and said side wall,

said water slider being provided at a position located near one side thereof with a portion which is displaced inwardly from said side wall, said slide surface being sloped downwardly in a lateral direction toward said inwardly displaced portion, whereby said boat is caused to be directed laterally along said sloping surface into contact with said side wall having said inwardly displaced portion.
