U.S. Pat. No. 5,387,159: Continuous wave generating apparatus for simulated surfriding.

 

What is claimed is:

1. A wave-generating apparatus, wherein a continuous wave is formed suitable for various
          surfriding sports including surfing, boogie-boarding and bodysurfing, said apparatus comprising:
          a carriage-support means having a carriage frame structure including a base frame on which said carriage frame structure is mounted;
          an elongated tube rotatably cradled in said carriage support means and having oppositely disposed open ends;
          a cap member mounted over each of said open ends of said tube and including an access opening;
          a reservoir formed in said tube by said cap members to hold a given amount of water within said tube during the rotation thereof;
          means for rotatably supporting said tube in a horizontal position within said carriage support means; and
          drive means for rotating said tube to create a centrifugal force, wherein the water is forced outwardly to define a cylindrical wall of water about the interior surface of said tube, whereby a continuous wave is formed in the upwardly rotating side of said wall of water.

2. A wave-generating apparatus as recited in claim 1, wherein said tube is defined by a horizontally positioned cylindrical housing, and wherein said cap members are each formed with an annular wall to define the depth of said reservoir.

3. A wave-generating apparatus as recited in claim 2, wherein said means for rotatably supporting said tube in a horizontal position within said carriage support means comprises a plurality of wheels mounted to said carriage frame structure and said base frame; and wherein said wheels are positioned for engagement with said cylindrical housing.

4. A wave-generating apparatus as recited in claim 3, wherein said plurality of wheels includes:
          a first dual-axle drive assembly mounted to said base frame adjacent one side of said cylindrical housing, a pair of said wheels being mounted at each end of said first dual axle drive assembly, and said dual-axle drive assembly being operably connected to said drive means; and
          a second dual-axle drive assembly mounted to said base frame adjacent the opposite side of said cylindrical housing, a pair of said wheels being mounted at each end of said second dual-axle drive assembly.

5. A wave-generating apparatus as recited in claim 4, including first and second spring-biased axle assemblies, each having wheels mounted thereon, and wherein said first and second spring-biased axle assemblies are mounted on said carriage frame structure and positioned to engage said cylinder housing on opposite sides thereof.

6. A wave-generating apparatus as recited in claim 5, wherein all of said wheels include traction means for frictional engagement with said cylindrical housing.

7. A wave-generating apparatus as recited in claim 6, wherein said traction means is defined by tires.

8. A wave-generating apparatus as recited in claim 7, wherein said apparatus includes restraining means mounted on said base frame to engage each of said cap members, thereby restraining movement of said cylinder housing along the longitudinal axis thereof.

9. A wave-generating apparatus as recited in claim 8, wherein said drive means comprises a motor, a transmission and a torque converter.
