Abstract (en)
[origin: US4986331A] The invention relates to a drive for closures of apertures, more particularly sectional gates. The sectional gate is made up of slats 1a-1c directly hinged to one another and guided in vertical and horizontal rails 3, 5 on both longitudinal edges. In the deflecting zone between the vertical portion and the horizontal portion of the aperture closure, associated with each edge of the aperture closure is a sprocket wheel 6 engaging with a roller chain. The rollers 21-24 of the roller chain are disposed on pivot pins 17-20 borne by locking members 10-12. The locking members 10-12 are inserted in the ends of every second hollow slat 1a, 1b, 1c. The pivot pins 17-20 are so arranged as to be in alignment with the hinge points 13-15 of the slats 1a-1e hinged to one another.
