Expanding structural system of bows and sliding rods (Machine-translation by Google Translate, not legally binding)

The invention relates to a structural system of a light folding cover to cover enclosures such as swimming pools, sports courts, greenhouses or any other that needs to be covered and discovered. It is characterized because it is formed by a set of arches arranged in vertical planes that start on rolling elements or other type of displacement elements. Said arcs are connected to each other by means of connecting rods or biarticulated rods, combining connecting rods of fixed articulations with connecting rods of sliding joints, which allows the folding and unfolding. The arches can have any geometry or configuration, being able to have a polygonal shape, solid section, honeycomb or latticework.

Se caracteriza porque está formado por un conjunto de arcos dispuestos en planos verticales que arrancan sobre elementos de rodadura u otro tipo de elementos de desplazamiento. Dichos arcos están conectados entre sí mediante bielas o barras biarticuladas, combinando bielas de articulaciones fijas con bielas de articulaciones deslizantes, lo que permite el plegado y desplegado. Los arcos pueden tener cualquier geometría o configuración, pudiendo tener forma poligonal, sección maciza, alveolada o en celosía.
