Abstract: A sectional closing door having a plurality of interconnected panels, where each panel of the sectional door, except the upper and lower panels, includes matching profiles which interlock and are guided on matching profiles of adjacent panels to form a swivel joint and that the guiding of the profiles relative to each other is obtained with an angulation such that, when one panel is positioned at 90.degree. relative to the adjacent panel, joining is insured with a component acting as a rider. The rider is designed with a U-shape that ensures it is connected to and integrated in one of the profiles of the end parts such that when one panel is swivelled to the maximum extent relative to another adjacent panel, the rider functions to insure a permanent joint and prevents the panels from becoming dislocated.

Abstract: A sectional door includes a plurality of consecutively coupled panels, each panel having at least one profiled form over at least a portion of a length of an end thereof, the at least one form defining a swivel joint between coupled panels. The panels, as coupled, can move between a vertical position and a horizontal position in order to allow door opening or closing. Preferably, the door includes a top panel, a bottom panel and a plurality of intermediate panels coupled there between in which each intermediate panel include a pair of profiled forms along at least part of the length thereof of each end. One of the forms includes an interior curved profile sized to allow the positioning and housing of connecting bars over at least a portion of the length of the profile, the connecting bars being associated to allow moving of all of the coupled panels.
