Abstract
Hardware for tilting doors, intended for each side of the door essentially characterized in that it is constituted by a lever arm articulated to a vertical plate anchored to one side of the door frame, which arm is subjected at one end to the action of a recovery spring associated with the frame, while the opposite end of the arm is articulated to a profile vertically joined to the bracket, arranged for the articulation of the end of a connecting rod arm also associated with the possibility of rotation to the plate anchored to the frame, so that when the door is closed, the connecting rod arm is arranged parallel to the vertical profile, while the lever arm forms an acute angle with said profile, the spring being at its maximum extension, position that will be modified when turning both arms with respect to the plate until getting the opening of the door that will swing until the horizontal position such.
