A device for automatic closing of a door, to be applied to a hidden hinge having two bodies articulated with each other by a pair of arms and adapted to be constrained to one of the two bodies and to be inserted, together with the body, into a cavity obtained in the leaf, includes a translating element to be engaged with an articulation arm of the hinge; an elastic member interposed between a first element associated with the translating element and a second element associated with the body of the hinge, and configured to be loaded during the opening of the leaf and to cause the automatic closing of the leaf by releasing the stored energy; and a system that varies the preloading of the elastic member and is configured to modify the distance between the first and the second elements, between which the elastic member is interposed.

Furniture damper
11992122 · 2024-05-28 · ·

A furniture damper includes a damper housing, a fluid chamber therein, a damping fluid therein, and a piston displaceably supported within the fluid chamber. A switch element can be moved, when a damping stroke is below a predetermined pressure threshold value, into a first position in which the channel of the piston is at least partially covered by the switch element and a first flow rate of the damping fluid streams through a channel of the piston. The switch element is also configured to be moved, when the damping stroke is above the predetermined pressure threshold value, from the first position into a second position in which the channel of the piston is at least partially unblocked by the switch element and a second flow rate of the damping fluid streams through the channel of the piston, with the second fluid rate being larger than the first fluid rate.

Hydraulic hinge, in particular concealed hinge for doors
10301859 · 2019-05-28 · ·

A hydraulic hinge comprising a fixed element anchorable to a stationary support structure and a movable element anchorable to a closing element. The fixed and movable elements are mutually coupled in such a way that the latter rotates with respect to the former about a first longitudinal axis between an open position and a closed position. One of the fixed element and the movable elements includes at least one working chamber defining a second longitudinal axis, which comprises at least one portion which includes: a plunger member sliding along the second axis and a working fluid to hydraulically dampen the movement of the movable element. The plunger member is mutually connected with one of the fixed element and the movable element so that the rotation of the latter corresponds to the sliding of the former.
