<p>The device (300) has multiple sections articulated between each other, where sections are folded sliding in a housing extending along a lower horizontal plane (310). The sections are guided, by parallel door frames (321, 322) of a facade, in a path along a contour of an access opening in the facade. The opening is extended in a cover, and a motor controls opening and closing of a sectional door (340). A balancing mechanism stabilizes the sectional door in position between a close position and folded position.</p> |
