<p>The invention concerns a device for making waves in a liquid (2) contained in a pond (1) such as a swimming pool, by the substantially vertical reciprocating motion of a body placed within the liquid or at the surface thereof. The body is a shell (3) capable of being filled with said liquid (2). The shell (3) is connected by linking means (4) to an element capable of periodically applying an upward-oriented force in a substantially vertical direction, then in lowering said shell (3) again. The shell (3) preferably comprises a horizontal base and substantially vertical side walls.</p> |
