Water jump course
First Claim
Patent Images
1. A water jum course for a boat with a front wheel and a rear wheel, characterized in that:
- the course is a circuit with a water trough adjoining a water tank at the lower end of a jump slope having a roller surface for the wheels of said boat, said water trough being directed past an exit platform and an entrance platform to an incline where the longitudinal conveyor connecting the upper end of the incline to the upper end of the jump slope; and
an end segment mounted to the slope lower end and movable between a normal upper position wherein the end segment forms a continuation of the rolling surface of the jump slope and a lower position when the end segment is moved downwardly in response to the front wheel of the boat rolling over the end segment, wherein said end segment is upwardly biased against a stop into its normal upper position said end segment being operatively connected to a centrifugal mass for of the exerting an upward force on a front wheel and moving the end segment to its lower position out of the path of the rear wheel of said boat.

Abstract
A water jump course comprises a jump slope, a boat and a water tank. The boat has front wheels and rear wheels with different gauges. In the lift-off zone of the jump slope, the rolling surface for the rear wheels is curved less markedly upwards than the rolling surface for the front wheels. Alternatively, the wheels may be of the same gauge and the rolling surface for the wheels at the jump slope lower end is movable in the vertical direction. An air cushion may also be provided in the landing area of the boat.

3. A water jump course for a boat with at least one front wheel and at least one rear wheel, comprising:
-
a water tank; a jump slope having a rolling surface with a liftoff zone at a lower end of aid jump slope, said liftoff zone including a rigid end segment supported around a horizontal axis and movable between a normal upper position wherein the end segment forms a continuation of the rolling surface of the jump slope and a lower position when the end segment is moved downwardly in response to the front wheel of the boat rolling over the end segment, wherein said end segment is upwardly biased against a stop into its normal upper position, said end segment being operatively connected to a centrifugal mass for both exerting an upward force on the front wheel and moving the end segment to its lower position out of the path of the rear wheel of said boat. - View Dependent Claims (4)
