Abstract

An amusement water ride is provided including a water course for carrying one or more circular water rafts. The water course is provided with at least one downhill section for accelerating the water rafts into a splash point. A spin mechanism is provided near the top of the downhill section for imparting a spin to the water rafts as they move past the spin mechanism. The spin mechanism includes a movement retarding surface along one wall of the water course and a movement expediting surface along an opposite wall of the water course. The movement retarding surface is provided with a high friction coating which retards sliding movement in a downstream direction of the surface of the raft which contacts the movement retarding surface, and induces rotation of the raft and movement towards the opposite wall. As the raft rotates into contact with the movement expediting surface it encounters no frictional resistance, and the spin is accelerated by the force of gravity acting on the mass of the raft as it moves downhill. The spinning raft increases thrill and introduces uncertainty among the passengers regarding who will be in a position to be splashed when the raft hits the splash zone.

Claims

1. A spin mechanism for use with an amusement ride including one or more circular water rafts constrained within a water course having a floor and upstanding walls for containing and directing a flow of water for carrying said water rafts, the spin mechanism comprising:

a movement retarding means adapted to be interactive with a surface of the water raft for retarding the movement past of said water raft, said movement retarding means mounted to a first wall of the watercourse; and

,

a movement expediting means adapted to be interactive with the surface of the water raft for permitting free movement past of the water raft, the movement expediting means mounted to a second wall of the watercourse opposite said first wall;

said movement retarding means adapted to be extended a sufficient distance into the watercourse towards said movement expediting means to force a passing water raft into contact with the movement expediting means.

2. The spin mechanism of claim 1 wherein said movement retarding means and said movement expediting means are adapted to be mounted near the top of an inclined surface of the water course.

3. The spin mechanism of claim 1 wherein said movement retarding means is a first surface, inclined in a direction of the flow of water from said first wall towards said second wall, and of sufficient length to force a water raft, traveling along and in contact with the first surface, into contact with the movement expediting means.

4. The spin mechanism of claim 1 wherein said first surface is covered with a substance having a high coefficient of friction while in contact with the surface of the water raft.

5. The spin mechanism of claim 4 wherein said substance is a synthetic or natural rubber.

6. The spin mechanism of claim 1 wherein said movement expediting means comprises a plurality of substantially freely moving members having a circular cross-section along at least one axis.

7. The spin mechanism of claim 6 wherein said members are cylinders mounted for rotation about an axis which is substantially perpendicular to a plane of said floor.

8. The spin mechanism of claim 1 additionally including a means for moving said movement retarding means selectively towards and away from said movement expediting means.

9. An amusement ride comprising:

a water course including a floor and two upstanding walls on either side of said floor for containing and directing a flow of water;

at least one circular water raft having a surface for contacting said walls, and carried along said water course in a downstream direction;

a spin mechanism mounted along said water course, said spin mechanism including a movement retarding means interactive with said surface of said water raft for retarding the movement downstream of said water raft, said movement retarding means mounted to a first wall of the watercourse, a movement expediting means interactive with said surface of said water raft for permitting free movement downstream of the water raft, the movement expediting means mounted to a second wall of the watercourse opposite said first wall, and wherein the movement retarding means extends a sufficient distance into the watercourse towards said movement expediting means to force a passing water raft into contact with the movement expediting means.

10. The amusement ride of claim 9 wherein said water course includes at least one inclined portion down which said water raft will be carried by said flow of water, and wherein said movement retarding means and said movement expediting means are mounted along said inclined portion.

11. The amusement ride of claim 9 wherein said movement retarding means is a first surface, inclined from said first wall towards said second wall in said downstream direction, and of sufficient size to force said water raft into contact with the movement expediting means when said water raft moves in said downstream direction past said movement retarding means.

12. The amusement ride of claim 9 wherein said first surface is covered with a substance having a high coefficient of friction when in contact with said surface of said water raft.

13. The amusement ride of claim 12 wherein said substance is a synthetic or natural rubber.

14. The amusement ride of claim 9 wherein said movement expediting means comprises a plurality of substantially freely moving members having a circular cross-section along at least one axis.

15. The amusement ride of claim 14 wherein said members are cylinders mounted for rotation about an axis which is substantially perpendicular to a plane of said floor.

16. The amusement ride of claim 9 wherein said movement retarding means can be selectively moved towards and away from said movement expediting means.

17. An amusement ride comprising:

a water course including a loading station, an unloading station, and a channel between said loading and unloading zone, said channel including a floor and two upstanding walls on either side of said floor for containing and directing a flow of water, and at least one inclined section located downstream of said loading station, and in which the elevation of said floor inclines downwardly in a downstream direction;

at least one circular water raft having a surface for contacting said walls, and carried along said water course in a downstream direction from said loading station to said unloading station;

a spin mechanism mounted along said water course, said spin mechanism including a movement retarding means interactive with said surface of said water raft for slowing the movement downstream of said water raft, said movement retarding means mounted to a first wall of the watercourse, a movement expediting means interactive with said surface of said water raft for permitting free movement downstream of the water raft, the movement expediting means mounted to a second wall of the watercourse opposite said first wall, and wherein the movement retarding means extends a sufficient distance into the watercourse towards said movement expediting means to force a passing water raft into contact with the movement expediting means.

18. The amusement ride of claim 17 wherein said spin mechanism is located along said inclined section.

19. The amusement ride of claim 17 wherein said movement retarding means is a surface extending in a downstream direction from said first wall towards said second wall and covered with a substance having a relatively high coefficient of friction when in contact with said surface of said water raft.

20. The amusement ride of claim 17 wherein said movement expediting means provides a surface having a relatively low coefficient of friction when in contact with said surface of said water raft.
