A wave spring (10) is formed in which linear relation is retained between a load (P) and a deflection (S). Thereby, the degree of freedom of design of springs is enhanced. In forming a spring structure by coiling a spring material having flat cross section, a clothoid curve is selectively used as a shape-determining factor for the spring structure.

A wave absorber comprising a foamed resin and a dielectric loss material dispersed therein, wherein the foamed resin is a foamed melamine resin obtained by foaming a resin composition comprising, as the main components, a melamine-formaldehyde condensate and a foaming agent. The wave absorber alleviates the problems of the prior art, and is lightweight and superior in self-extinguishing property, and shows an excellent wave-absorbing property owing to a uniformly dispersed dielectric loss materi...

A wave barrier for protecting users and their possessions at a beach location close to the water from becoming wet from waves crashing into their location. The wave barrier includes a flexible wall sheet with a plurality of spaced apart elongate poles coupled thereto. The lower ends of the poles are downwardly extended from a bottom edge of the wall sheet. The proximal edge of a ground sheet is coupled to the wall sheet along the bottom edge of the wall sheet.

A wave generator for generating waves in pools and the like for water sports, amusement and the like. The wave generator has a water inlet/outlet disposed and configured so that when acting as an inlet, it will draw water from the pool and not air from above the pool. The wave generator includes a sealable chamber coupled to the water inlet/outlet for temporary storage of a substantial quantity of water at elevations above the level of water in the pool. In operation the chamber is sealed and ai...

A more efficient paddle construction having a blade and a stem extending there from and wherein the blade has a rippled like surface which are latitudinally running wave like curled fins. This arrangement is such that there is a greater resistance to the flow of water up and around the blade when the paddle is being drawn in a scooping propelling stroke.

A swimming lane wave suppressor, for use in suppressing waves and for use in the demarcation of swimming pool lanes, comprised of two cylindrical cores having a plurality of fins radially extending from their outer surface, the inner surface of the first core having a larger diameter than the inner surface of the second core. The fins are positioned substantially coextensively in a lane of each core. At least one spacer is circumferentially positioned between and connected to the core members an...

An apparatus and system for dissipating water wave energy and for shoreline control including a module with a generally hollow body, a pair of opposed flanges attached to adjacent corners of the body, a pair of axially aligned mounting apertures in the flanges for connecting the body to similar bodies for forming a wave energy dissipation system, and a recess disposed between the flanges. Each recess contains a plurality of boundary layer interrupting projections for substantially disrupting any...

A wave forming generator which can repeatedly produce and launch singular waves across the surface of a body of water. The wave generator includes an air compressor interconnected with are a large air pressure holding tank. A hydraulic actuated valve is fitted onto the air pressure tank. Piping is then connected to the valve and ran out and down to join and connect to several main water tubes, cannons, pipes, or anything that can take the form of a long round elongated chamber. The elongated cha...

A wave generator including a base seat and an annular adjustment seat. A bottom face of the base seat is formed with a bubbling hole. Multiple sprinkling holes are formed along the circumference of the bubbling hole. The bottom edge of the adjustment seat is formed, with multiple downward extending parallel cleaning pins respectively corresponding to the sprinkling holes. When a user moves the base seat upward, permitting the water to flow out from the bubbling hole, the cleaning pins are respec...

A break intercepts waves moving in an anticipated direction along a water surface. Modular elongated floats are aligned end-to-end and extend generally perpendicular to the anticipated direction of the waves. Modular elongated ballast containers aligned end-to-end depend from the floats. The float is wider than the waves. Ballast in the containers is coordinated with the buoyancy of the floats so that the floats extend higher above the water surface than the waves and the container depends below...
