Abstract: The invention is a water amusement ride, comprising at least one water vehicle, which can be moved in a body of water and which comprises seats for accommodating passengers. A platform is provided, which extends out of the water surface in an idle state of the water amusement ride and is beneath the water surface in an operating state, and a platform carrier is provided, which lifts the platform out of the water surface in the idle state. According to the invention, the platform carrier and/or the platform comprises at least one floating body. The switch to the idle state (and possibly also back to the operating state) can be completed more quickly and with lower force and energy consumption in comparison with a traditional water amusement ride.

Abstract: A retractable athletic surface for use on an athletic field containing an opening within the athletic field into which a foundation is secured. Supporting the retractable athletic surface in the opening is a platform. A drive motor secured to the platform drives one or more systems for raising and lowering the platform within the opening. Upper and lower stops are secured to shaft stop assemblies which are present within slots inside walls of the foundation. These upper and lower stops support the retractable athletic surface in either a raised or lowered position.

Abstract: An amusement apparatus comprising an elongated flume which has a fluid medium provided therein. A plurality of passenger vehicles are carried in the flume. Lifting mechanisms are provided for selectively raising and lowering various areas of the flume causing the fluid medium to travel as a wave in a continuous path around the flume and propel passenger vehicles floated thereon.

Abstract: An adjustable seesaw ski-track includes a stationary central part and separate wing sections pivotally connected to opposite sides of the central part, each wing section including a horizontal platform section and a plurality of pivotally connected wing sections extending between the platform and the central part. A coupling rod connects the two wing sections together, and a hydraulic cylinder assembly is connected to one of the wing sections so as to raise and lower its platform section relative to the central part, thus pivoting the wing section upwardly and downwardly relative to the central part, the coupling rod causing the other wing section to respectively pivot downwardly and upwardly relative to the central part.

Abstract: An endless water way is supported by a superstructure and includes a bottom wall and side walls extending upwardly from the bottom wall to form a trough. A pump system effects continuous forward flow of water through the trough of the waterway. A guide track is supported on the waterway above the trough. A plurality of vehicles for transporting passengers from station to station are buoyantly supported by the guide track in the waterway. The guide track maintains the vehicles at a selected depth in the waterway. Each vehicle is provided with braking apparatus for frictionally engaging the guide track of the waterway to slow and stop the vehicles. The continuous forward movement of water in the waterway forwardly propels the vehicles from station to station. A plurality of endless waterways form continuous loops that radiates outwardly from the main terminal to provide transportation around the loops to and from the main terminal.
