Abstract: A low shelter swimming pool roof system is provided. The system can include, over a portion (P?) at least of its length, juxtaposed roof elements (I?) and juxtaposed roof elements (I). The distance that delimits the external chord of each of the longitudinal edges (220a?) and (220b?) of the roof elements (I?) resting on the support edge (S) of the pool and connected by two roof arcs (210?) can be shorter than the distance which delimits the internal chord of the two longitudinal edges (220a) and (220b) the roof elements (I) of the other portion (P) resting on the support edge (S) of the pool and connected by two roof bows (210). Such an arrangement enables the first portion (P?) of roof elements (I?) to be nested in the second portion (P) of relatively larger roof elements (I) thereby partially exposing the pool over a length corresponding to the displacement of the mobile portion (P?) of roof elements (I?).

Abstract: The invention concerns a swimming pool cover consisting, over a portion (P′) at least of its length, of juxtaposed roofing elements (I′) whereof the distance which delimits the external chord of each of the longitudinal edges (220a′) and (220b′) resting on the support edge (S) of the pool and connected by two roof bows (210′) is shorter than the distance which delimits the internal chord of the two longitudinal edges (220a) and (220b) resting on the support edge (S) of the pool and connected by two roof bows (210) of the juxtaposed elements (I) of the other portion (P) of the roof to enable the first portion (P′) of small elements (I′) to be nested in the second portion (P) of large elements (I) thereby exposing partly the pool over a length corresponding to the displacement of the mobile portion (P′) of elements (I′).
