Abstract: A low-bulkiness hinge for closing a closing element anchored to a stationary support structure, such as a wall, a frame or a floor includes a hinge body which includes a longitudinal operating chamber defining a first axis, a pivot coupled to the hinge body to rotate around a second axis between the opening and closing positions of the closing element, and a slider slidable in the operating chamber along the first axis. The operating chamber has a first seat for the pivot and a second seat for the sliding of the slider, which includes a shaft and an operative head that are mutually coupled. The hinge body has a first opening for inserting, perpendicularly to the first axis, the operative head into the second seat and a second through opening for inserting, coaxially to the first axis, the shaft into the housing. The hinge further has the shaft and the operative head fixed to one another after insertion in the second seat (so as to form a unitary assembly integrally slidable along the first axis.

Abstract: A linear actuator includes a jacket defining an axis, and a rod having an end cylinder tightly slidable within the jacket and an opposite end sliding between a rest position and a working position. The end cylinder divides the jacket into a first and second variable volume compartment fluidically independent from each other, one of the first or second variable volume compartment being fluidically insulated and under vacuum, the other one fluidly communicating with the outside environment. The jacket has an abutment member having a non-return valve mechanism adapted to discharge ambient air that may be entrapped between the end cylinder and the abutment member.

Upon the passage of the opposite end of the rod from the rest position to the working position, one of the variable volume compartments passes from a minimum volume to a maximum volume, in order to suck the rod and automatically recall the opposite end from the working position to the rest position.

Abstract: A hinge device includes a fixed element, a movable element, and a slider. One of the fixed or the movable elements defines a working chamber receiving the slider, and the other one has a pivot causing the slider to slide upon a rotation of the pivot. The working chamber contains a working fluid and is separated into a first and a second variable volume compartments by a plunger of the slider, which includes a first valve providing fluid communication between the compartments. A first duct passing through a closing cap of the working chamber has a second valve in fluid communication with the first and second compartments and spaced from the plunger for a first part of a stroke of the plunger. During a second part of the stroke, the plunger acts upon the second valve to cause the closing element to latch toward an open or closed position.

A pin-inserted within the pass-through actuating member is provided to allow the mutual engagement of the pivot and the bushing. The first tubular half-shell includes an end portion susceptible to rotatably support the pivot, the second tubular half-shell and the bushing are coaxially coupled to each other, and the bushing and the first tubular half-shell are mutually unitarily coupled.

Abstract: A system for the quick mounting of a glass shutter or door to a support frame includes a mounting plate having a first anchoring element to the top of the supporting frame and a second anchoring element to the glass shutter or door. The mounting plate includes a downwardly extending pivot defining an axis and a hinge device having a seat for the pivot.

A slip-preventing system prevents the separation by gravity of the hinge device from the mounting plate after coupling the pivot to the seat. The second anchoring element is removable so as to allow an operator to mount/dismount the glass shutter or door onto/from the support frame with the hinge device in the working position mounted on the top of the support frame.
