Abstract:
1. A mechanism for the installment of a shutter having a rotational-sliding movement to a frame, the mechanism comprising: a guide connected to a horizontal strut of said frame; a translation element slidably arranged in said guide; a first pivot mechanism that pivotally connects a central region of said shutter to said translation element about a first vertical axis; an upper arm having a first end and a second end; a lower arm having a first end and a second end; a second pivot mechanism that pivotally connects the first ends of said upper and lower arms to the frame adjacent to a first jamb of the frame about a second vertical axis, the second ends of said upper and lower arms being rigidly coupled to a rod running an entire height of the shutter, rotating about a third vertical axis, said third vertical axis being interposed between the first vertical axis and the second vertical axis, said second pivot mechanism providing an adjustment of a distance of said second rotation axis from the first jamb of the frame, said second ends of said upper and lower arms being reciprocally rigidly connected by said rod, and said rod being fixed to at least one of the upper and lower arms with a rigid connection device providing a non-welded joint between the rod and the at least one of the upper and lower arms.
