Double-pivot synchronization mechanism for opening and closing two leaves

摘要

The double-pivot synchronization is characterized in that each leaf is connected to an opening arm by an opening pivot. The other end of the opening arm is connected to a second pivot. This second pivot adds a degree of freedom to the components that are connected to it and thereby, frees them from the constraints imposed by the rotation of the leaves on the hinges. These components can thus be synchronized more easily. The mechanism comprises an arrangement of rigid elements, connected between them and attached to the frame.;A first embodiment has a rail and is particularly suitable for manufacturers of furniture and cabinets who use custom-made components. A second embodiment, with rail, is better suited to a shallow frame and simplifies the adjustment to the width of the leaves. A robust and versatile third embodiment has gear teeth and mainly targets walk-through doors and recessed synchronization mechanisms.

1. Synchronization mechanism for the opening and closing of two leaves (2 and 3) comprising:
Two hinges (4) or more, or any other mechanism to rotate these leaves around two equivalent vertical axis; Two opening pivots (5), fixed to the top of the leaves (2 and 3), near the ends fitted with hinges (4), on the frame side (1); Two opening arms (6), whose one end is connected to an opening pivot (5) and the other end to a second pivot (8 or 12); Characterized in that the transversal synchronization (front-rear) of components is achieved by the transversal movement of the second pivot (8 or 12), while the symmetric inversion (left-right) relies on the rotation of the components around said second pivot.
