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.
