Patent Granted The design is intended for use in garages for opening and closing openings. This model is made in accordance with US Pat. No. 8,327,908 and is based on the key clauses of the claims. The design has four sections that are folded like an accordion, which ensures a substantial compactness of the structure. Additional advantages also include: a small headroom opening, high opening speed of 5-8 seconds, no ropes and torsion springs, which significantly reduces the cost of low maintenance and provides a longer service life. The model is simple in design, therefore, reliable in operation and inexpensive in mass production.
