A roto-translating system for opening and closing a wing which is configured to be mounted on a frame of the wing is provided with a first guide and a second guide arranged so as to define an angle greater than or equal to 90; a first carriage and a second carriage which are configured to be coupled to an upper edge of the wing and to engage in a sliding manner the first guide and the second guide respectively; a spacer arm provided with a first end, which is configured to be fixed to a first structural element of the frame in a rotating manner about a first vertical axis, and a second end which is configured to be coupled to a lower edge of the wing.

A main tilting door for the closure of an access opening of a room includes two fixed uprights, including vertical sliding guides, and one fixed crosspiece associable with each other to define a fixed frame. The door includes two movable uprights and two movable crosspieces associable with each other to define a movable frame. The door includes tilting movement device/unit/component/apparatus or the like including two lateral supporting arms each having a first end which can be hinged to an intermediate area of the movable uprights and a second end which can be hinged to a top of the fixed uprights; and two sliding supports movable along the vertical sliding guides. The door includes panels associable with the movable frame. At least one of the movable uprights and the movable crosspieces includes a sliding track and cursors movable along the sliding track, the panels associable with the cursors.

A door assembly provides a one-piece, swing up door panel known as a California-type garage door, with a mid-height pivot axis travelling vertically during operation of the door. The rotational motion of the door is caused by a follower riding in a slot of a plate, with the follower being offset relative to the pivot axis and fixed relative to the door panel. The slot places forces on the follower during motion of the door panel between the door-closed position and the door-opened position, with the offset causing the forces to act as moments rotationally accelerating and rotationally decelerating the door between the door-closed position and the door-opened position. The slot preferably has a start non-rotational portion and an end non-rotational portion during which the door panel translates vertically without pivoting of the door panel, as well as different intermediate portions which have different rotational speeds.
