MECANISMO DE SOPORTE Y DESPLAZAMIENTO DE ARCOS MOVILES EN CUBIERTAS RETRACTILES DE CAJAS DE CAMIONES

Mechanism for supporting and moving mobile arches in retractable covers of truck boxes, which are of the type intended to be implanted in the box (1) of a truck (2) and which incorporate a plurality of arches (3-3'-3'') in an inverted "U", to which a folding awning or cover (4) is linked, one of the arches (3'') being the closest to the cabin (6) integral with the box (1), while the rest of the arches (3-3'') are movable along guides (5), the rear arch (3') being movable through a traction mechanism using a cable, chain, strap or similar, as well as the rest of the arches because they are linked to the cover (4), is characterized in that the guides (5) have an omega profile, in which a lower groove (7) is defined. choked, so that the lateral chokes of said slot determine separate rolling tracks (8-8') for the wheels (9) of a cart (10), guides that extend along one of its side walls, the one that adapts to the side of the box (1) of the truck in two upper (11) and lower (12) tabs for fixing to the box (1), with the particularity that the carriage (10) is materialized in an "L" profile plate ", whose vertical branch includes holes for passage of the axles (13) of the corresponding wheels (9) for moving the cart on the rolling tracks (8-8'), vertical branch that has a thickness according to the width of the slot (7) through which it passes, extending below it to undergo a bend that ends in a horizontal surface, provided with holes (15) for screwing the lower end (16) of the arch (3-3').
