Abstract: The invention relates to an enclosure for a pleasure pool, which is completely or partially in the form of a rotunda and which comprises a plurality of rotary angular roof elements. The aforementioned rotary angular roof elements form an angular portion of the rotunda and rotate about the same vertical axis, each element comprising a frame framing at least one cylindrical filler panel. The frame includes a lower circular edge that rests on the ground and an upper edge from which at least two sections extend towards the rotation shaft, which sections join so as, together with the upper edge, to form a frame for an angular portion of the roof-forming filler panel. The roof elements are mounted to rotate about the same vertical axis in order to move between an open position and a closed position.

Abstract: The invention relates to a device (D) for mounting and guiding roofing modules (M) of the type consisting of a framework (100) connecting beams (110) and cross members (120) supporting a cover, the edge cross members (121 and 122) forming rims and resting on the edges of a swimming pool (P), said modules (M) being able to undergo horizontal translational movement (arrow F1) above the swimming pool (P) in order that said swimming pool (P) is covered or opened, said device being noteworthy in that it consists of a wheel (200) having a substantially vertical axis, -said wheel being mounted on a removable rotary shaft (300) mounted at the edge of the swimming pool (P), -the rolling surface (210) of which wheel allows a relative rolling of the rim of the modules (M) when said rim comes into contact during the horizontal translational movement (arrow F1), -the lower face (220) of which wheel engages with a projection (400) on the rim (121, 122) which comes under the wheel (200) in order to restrain the module (M) i
