Abstract
A system for the rotary coupling of a closing element about a stationary support structure includes a first hinge device and at least one second hinge device. The first and the second hinge devices include a movable element having a hinge body and a fixed element having a pivot. The hinge body and the pivot are rotatably coupled to each other to rotate between the open and closed position of the closing element. The first and second hinge devices can be coupled to the same coupling element so that they cooperate to control the rotation of the closing element between the open and the closed position.

A system for a controlled rotary movement of a closing element around a rotation axis with respect to a stationary support structure, the system comprising:
- a first hinge device;
- and
- a second hinge device,
- wherein each of the first hinge device and the second hinge device comprises:
- a fixed element, which can be anchored to one of the stationary support structure and the closing element;
- a movable element, which can be anchored to the other one of the stationary support structure and the closing element,
- wherein one of the movable or the fixed element includes respectively a first or a second hinge body, the other one of the movable or the fixed element comprising respectively a first and a second pivot defining a respective first or second axis, the first and the second hinge body and first and second pivot being rotatably coupled to enable a rotation around the first and the second axis between a first operative position corresponding to an open or a closed position of the closing element and a second operative position corresponding to the closed or the open position of the closing element,
- wherein the first and the second hinge device are configured to be be-coupled with the same closing element in longitudinally staggered positions so that the first and the second axis coincide with each other and with the rotation axis,
- wherein the first and the second hinge device cooperate to control the rotation of the closing element around the rotation axis between the closed position and the open position of the closing element,
- wherein each of the first and the second hinge body comprises a working chamber defining a respective third axis perpendicular to the first and the second axis and a respective slider slidable in the working chamber, the first and the second pivot including first and second cams, the first and second slider comprising first and second cam follower means operatively connected with the first and the second cams so that, to a relative rotation of the first and the second pivot and the first and the second hinge body, there corresponds a sliding of the first and the second slider,
- wherein the first hinge device comprises control means acting on the respective first slider to brake a mutual rotation respectively of the first hinge body and the first pivot, the second hinge device comprising motion promotion means acting in coordination with the control means on the respective second slider to promote a mutual rotation respectively of the second hinge body and the first or the second pivot,
- wherein the first cam of the first hinge device comprises a first operative surface having an initial angular portion, a first convex operative portion, and a concave portion,
- wherein the second cam of the second hinge device comprises a second operative surface having an initial concave portion, a second operative portion that is convex and different from the first operative portion, and an additional concave portion, the first and the second operative portions being configured so that upon the rotation of the first hinge body and of the first pivot from the one of the first or the second operative positions over an angular section, the first slider and the second slider slide over a different length section, and
- wherein the first and the second operative portions are mutually configured so that along the section of the rotation of the closing element from the open position to the closed position, the first hinge device acts on the closing element with a first torque and the second hinge device acts on the closing element with a second torque counteracting the first torque, the second torque being lower than the first torque so as to allow the rotation along the section of the rotation of the closing element from the open position to the closed position, the first and the second operative portions being configured so that the first and second torques are variable upon the rotation of the first and the second hinge body and of the first and the second pivot along the section of the rotation from the one of the first or the second operative position to the other one of the first or the second operative position so as to allow the rotation with a predetermined speed of the closing element along the section from the open position to the closed position.
