    Abstract: A sectioial overhead door is disclosed with a door leaf comprising several consecutive hinging panels (10, 10', 10") which are guided in the known way by rollers (11) in horizontal tracks and in tracks (12, 12', 12") joined to them to form a bow and are provided with a balancing device (15) in the form of approximately horizontal helical tension springs. The latter are designed to be space-saving, in particular with low drop heights, underneath the horizontal track sections extending into the building, such that on each of the outer side regions (27) of the horizontal track sections (12, 14) facing away from one another one or more helical tension spring units (16) are arranged approximately parallel to one another and one below the other. At least some of the helical tension spring units (16) consist of at least two coaxial helical springs (17, 18), the turns of which are mutually opposing and intersecting.

    Abstract: The assembly comprises an extension spring anchored at one end to a winch mounted to the door opening frame. A double-grooved pulley is mounted on a plate secured to the free end of the spring. A fixed second double-grooved pulley is mounted to the door frame. A pair of cables are anchored at one end to the door frame and extend in parallel to pass around the two pulleys. After the second pulley, the cables separate and extend down to the bottom corners of the door, to which they are secured. Upon release of the door latch with the door down, the spring contracts and, through the first pulley, applies an equal pull to the two cables so that they move at the same rate, thereby raising the door smoothly.

    Abstract: An operator for an overhead door comprises a fluid actuated device including a cylinder and a cooperating piston. The piston rod carries a pair of cable sheaves. Another pair of sheaves are rotatable on a fixed mounting. A cable is wound around pulleys in corresponding pairs. Each cable has one end anchored and another end fastened to the door so when the fluid actuated devices spread the pair of sheaves, the door lifts. Pressurized fluid is relieved from the cylinder to let the door close under its own weight. Electric circuits for actuating the hydraulic circuit are shown.
