The wave generator may include a chassis for support of other components, have structure for engaging a supporting environmental surface or object, an agitator to be periodically projected into the water, and an oscillating device for periodically projecting the agitator into the water and withdrawing the agitator from the water to enable subsequent impingements against the water. The oscillating device includes a rocker arm, a powered crank mechanism to rock the rocker arm, and a support arm to hold the agitator below the elevated end of the rocker arm, thus enabling the agitator to impinge against the surface of the water. Optionally, functional components of the wave generator are covered by a cover simulating e.g. a whale. Optionally, the wave generator includes a protective cage held in the water below the agitator. ## Claims ### Claim 1 A wave generator for generating waves on the surface of a body of water when supported on an environmental object proximate the body of water, the wave generator comprising: a chassis including an environmental support configured to engage the environmental object and secure the wave generator stably thereto; a rocker arm including a proximal end and a distal end, and a post pivotally supporting the rocker arm above the chassis such that the distal end of the rocker arm extends laterally beyond the chassis; an oscillating device supported by the chassis and coupled to the rocker arm between the proximal end of the rocker arm and the post; an agitator depending from the rocker arm between the post and the distal end of the rocker arm, the agitator configured to present a contact surface for generating a wave responsive to the agitator being projected into the surface of the body of water; and a flexible cover covering the chassis and the oscillating device, wherein the flexible cover visually simulates a marine animal, the flexible cover including a body appendage of the marine animal, and wherein the rocker arm is contained within the body appendage. ### Claim 2 (depends on 1) The wave generator of claim 1, wherein the environmental support comprises a base including a bottom surface for resting on a horizontal planar environmental surface. ### Claim 3 (depends on 1) The wave generator of claim 1, further comprising a vertically oriented support arm pivotally coupled to the rocker arm at one end of the vertically oriented support arm and coupled to the agitator at an opposed end of the vertically oriented support arm. ### Claim 4 (depends on 3) The wave generator of claim 3, further comprising an adjustment mechanism enabling the agitator to be positioned selectively at a variety of distance intervals from the rocker arm. ### Claim 5 (depends on 4) The wave generator of claim 4, wherein the adjustment mechanism comprises a series of holes in the vertically oriented support arm and a pin securing the vertically oriented support arm to the rocker arm. ### Claim 6 (depends on 1) The wave generator of claim 1, wherein the oscillating device comprises a crank including a shaft and a journal fixed to and offset from the shaft, a motor rotatably coupled to the shaft, and a connecting rod coupled to the journal and to the rocker arm such that rotation of the crank causes the rocker arm to raise and lower the agitator relative to the surface of the body of water. ### Claim 7 (depends on 6) The wave generator of claim 6, wherein the motor is an electric motor, the oscillating device further comprising a battery and circuitry electrically connecting the battery to the motor. ### Claim 8 (depends on 7) The wave generator of claim 7, further comprising a switch configured to open and close the circuitry, the switch located on the exterior of the wave generator. ### Claim 9 (depends on 1) The wave generator of claim 1, wherein the bottom surface of the base includes at least three points defining a horizontal plane able to support the wave generator stably when the wave generator is placed on a planar horizontal supporting surface. ### Claim 10 (depends on 1) The wave generator of claim 1, further comprising a cage supported from the base below the agitator when the base of the wave generator rests above the environmental horizontal surface, wherein the cage is configured to surround and receive the agitator when the agitator is lowered into the body of water by the rocker arm. ### Claim 11 (depends on 1) The wave generator of claim 1, wherein the flexible cover comprises an openable closure providing access to the oscillating device when the openable closure is open. ### Claim 12 (depends on 1) The wave generator of claim 1, wherein the marine animal is a fish or a whale.
