Abstract: A closing hinge device includes a fixed element, a movable element and a pair of counteracting elastic members. One of the movable element or fixed element includes a generally box-shaped hinge body with a pair of working chambers to slidably house the counteracting elastic members. The other of the movable element or fixed element includes a pivot having a cylindrical portion that includes a pair of substantially equal grooves angularly spaced at 180° and each having a helical portion, the grooves communicating with each other to define a single guide element passing through the cylindrical portion. The box-shaped hinge body includes elongated slots, a pin being inserted through the single guide element and through the elongated slots to slide therethrough, and the counteracting elastic members act on the pin to promote the automatic returning of the closing element from the open position to the closed position.

Abstract: A system for controlled rotatable movement of a closing element anchored to a stationary support structure includes a piston device and a hinge device. The hinge device has a fixed element and a movable element reciprocally coupled to allow mutual rotation, a seat for removably inserting the piston device, and a pivot member with a cam element facing the seat to interact with the piston device. The piston device includes a tubular body, an actuating head external to the tubular body, a plunger member slidable within the tubular body, and an elastic contrast member acting on the plunger member for returning it from a retracted end position to an extended end position. The seat of the hinge body includes a pass-through or blind bore extending along an axis for providing access into the hinge body in a direction substantially parallel to or coinciding with the axis.

Abstract: A hinge device for rotatably moving a closing element includes a fixed element anchorable to a stationary support structure coupled to a movable element anchorable to the closing element for rotating around a first longitudinal axis between an open position and a closed position. The device further includes at least one slider movable along a second axis between a compressed and an extended position. One between the movable element and the fixed element includes at least one operating chamber defining the second axis so as to slidably house the slider, the other element including a pivot defining the first axis. The pivot and the slider are reciprocally coupled so that to the rotation of the movable element around the first axis corresponds the sliding of the slider along the second axis and vice versa.
