Abstract:
The main door (1) for the control of the access opening to a compartment, particularly a garage compartment, comprises: - a fixed portion associable with the access opening of a compartment and comprising two lateral uprights (2) and an upper crossbar (3); - a mobile portion including a leaf (4, 5) associated in a mobile way with the fixed portion; - at least a pulley (27) associated revolving with the top of at least one of the lateral uprights (2) and on which winds up at least partially a cable (28) connected to the leaf (4, 5) and to a counterweight (29); - an operating shaft (30) of the pulley (27) mounted on the upper crossbar (3); - a winding-unwinding device (34) mounted on the upper crossbar (3) and having a flexible element (35) which can be wound and unwound which is associated with the top of the leaf (4, 5); - an electric motor (36) mounted on the upper crossbar (3) and suitable for placing a driving shaft (37) in rotation; and - a transmission and distribution unit (38, 39, 40) of the motion of the electric motor (36) which comprises: - a first electromagnetic clutch (38) placed between the driving shaft (37) and the operating shaft (30); - a second electromagnetic clutch (39) placed between the driving shaft (37) and the winding-unwinding device (34); and - an electronic processing and control unit (40) which is electronically connected to the first electromagnetic clutch (38) and to the second electromagnetic clutch (39) and which is suitable for operating the first electromagnetic clutch (38), to transmit motion from the driving shaft (37) to the operating shaft (30), and for operating the second electromagnetic clutch (39), to transmit motion from the driving shaft (37) to the winding-unwinding device (34).
Abstract:
The sectional door (1) for the control of the access opening to a compartment, particularly to a garage compartment, comprises: - a fixed portion including two pairs of vertical guides (5, 6) suitable for extending in a direction substantially parallel to a respective shoulder of the access opening to a compartment; and a movable portion including: a leaf comprising a lower panel (7) and an upper surrounding panel (8), substantially rectangular in shape, extending over the entire width of the leaf and having the lateral sides thereof in sliding engagement along a respective side guide (5, 6); a pair of side support arms (11) each having one end thereof articulated in correspondence to the top of a respective pair of vertical guides (5, 6) and the other end thereof pivoted in correspondence to an intermediate zone (8c) of a respective lateral side of the upper panel (8); and articulated and slidable connection means (12) between the lower panel (7) and the upper panel (8), including a pair of lateral sliding guides (10) provided in correspondence to the lateral sides of the upper panel (8), and a pair of connection levers (13), each having one end (15) thereof in sliding engagement with a respective lateral sliding guide (10) of the upper panel (8) and a second end (14) thereof articulated at the top to the lower panel (7), whereby the lower panel (7) and upper panel (8) are movable between a completely closed position of the access opening, in which they are arranged in a substantially aligned sequence, one on top of the other, along the pairs of vertical guides (5, 6), and a completely open position, in which the upper panel (8) is overhangingly moved to project in the compartment starting from a zone in correspondence to the top of the pairs of vertical guides (5, 6), supported by the pair of side support arms (11) and the lower panel (7) is moved together with, and against the upper panel (8).
