<p>A mechanism for the installment of a door or other similar closure having a rotational-sliding movement, of the type comprising the following elements to associate to a shutter: first pivot means defining a first vertical axis for the pivoting of a shutter, in a substantially central region thereof, to translation means arranged so as to slide in a corresponding guide associated to the upper strut of a frame of a door; second pivot means with an axis parallel to the axis of the first pivot means, for the pivoting of two arms, a first upper one and a second lower one, that are both pivoted with one of their ends to the frame of the door or closure in proximity to a jamb to define a second rotation axis, and have the opposite ends reciprocally rigidly coupled by means of a rod, defining a third rotation axis interposed between the first axis and the second axis, passing through the shutter in the direction of the height thereof. The second pivot means are rigidly coupled to the frame with means for adjusting the distance of the second rotation axis from the nearby jamb of the door or the like; further the rod is fixed to at least one of the two arms with a rigid connection device that provides a non-welded joint between the rod and the arms. Such mechanism according to the invention facilitates and improves the installment of doors having a rotational-sliding movement.</p> |
