Abstract: 1. A manually actuated swing door (5), particularly for garages, of which the door leaf (11), resiliently held by levers (10), is guided in the lower region in the closed state as necessary through two lateral guide rollers (12) which are situated outside the door leaf and which bear constantly against guide surfaces (14) of a surrounding frame (7), which guide surfaces extend substantially vertically, the levers (10) being articulated, on the one hand laterally substantially in the middle region of the door leaf (11) and on the other hand in the vicinity of the upper ends of the guide surfaces (14), characterized in that the one end (20) of a first cable (22) is fixed in the region of the one guide roller (12), that this first cable (22), in a first component portion (23) is guided upwards, parallel to the one guide surface (14), is deflected substantially at right angles in the region of the one upper corner (27) of the surrounding frame (7), and in a second component portion (24) is guided parallel to the horizontal portion (9) of the surrounding frame (7) as far as the other upper corner (27) of the surrounding frame (7), is there again deflected substantially at right angles and in a third component portion (25) is guided substantially parallel to the first component portion (23) as far as the lower end region of the other of the other guide surface (14) and then, after another deflection substantially through a double right-angle, is guided upwards in a fourth component portion (26) and the other end of the first cable (22) is fixed to the other guide roller (12), that in the region of this other guide roller there is attached the one end of the second cable (21), that this second câble (21) in a first component portion (23) is guided upwards parallel to the other guide surface (14), is deflected substantially at right angles in the region of the other upper corner (27) of the surrounding frame and in a second component portion (24) is guided parallel to the horizontal portion (9) of the surrounding frame as far as one upper corner (27) of the surrounding frame, is there again deflected substantially at right angles and in a third component portion (25) is guided substantially parallel to the first component portion (23) as far as the lower end region of the one guide surface (14) and then, after again being deflected through a substantially double right angle is guided upwards in a fourth component portion (26)  and the  other end (19) of the second cable (21) is fixed to the one guide roller (12), that an upper guide pulley (28, 29) is disposed in the region of each upper corner (27) of the surrounding frame (7) and a lower guide pulley (30, 31) is disposed in the lower end region of each guide surface (14) of the surrounding frame (7) to deflect each cable (21, 22), that each upper guide pulley (28, 29) for the two cables (21, 22) is constructed in the form of a double pulley with a common axis of rotation and that the upper and lower guide pulleys (28, 29 and 30, 31) are rotatable about axes (32) which extend perpendicular to the guide surface (14).
