Abstract
A hinge for cold rooms or glass shutters includes a stationary support structure and a shutter movable between an open position and a closed position. The hinge includes a hinge body with a working chamber; a pivot coupled with the hinge body; a cam element unitary with the pivot; a plunger element sliding in the working chamber, the plunger element having a slider with an operative face interacting with the cam element; a counteracting elastic member acting on the plunger element to move it between a position proximal to the bottom wall of the working chamber and a position distal therefrom. The hinge body has a substantially plate-like shape. The cam element includes an elongated appendix extending from the pivot to come in contact engagement with the operative face of the slider. The pivot is placed at one of the side walls of the working chamber.

83. A low-bulkiness hydraulic hinge for rotatably moving and controlling a closing element (A) anchored to a stationary support structure (S) between an open position and a closed position, the hinge comprising:
-
a hinge body (10) anchorable to one of the stationary support structure (5) or the closing element (A), said hinge body (10) internally comprising a working chamber (11) with a front wall (13) and a bottom wall (12) faced thereto, said hinge body (10) having a substantially planar shape to define a first plane (π
′
);a pivot (20) defining a first longitudinal axis (X) anchorable to the other one of the stationary support structure (S) and the closing element (A), said pivot (20) and said hinge body (10) being coupled to each other to rotate around said first axis (X) between the open position and the closed position of the closing element (A); a slider (31) slidably movable within said working chamber (11) along a second axis (Y) between a position distal from said bottom wall (12) and a position proximal thereto, said pivot (20) and said slider (31) being reciprocally coupled so that a rotation of the closing element (A) around said first axis (X) corresponds to an at least partial sliding of said slider (31) along said second axis (Y), said slider (31) including an axial blind hole (35); a hydraulic damping system acting on said slider (31) to hydraulically damp a movement of the closing element (A) during opening and/or closing movement, said hydraulic damping system including a working fluid entirely contained in a hydraulic circuit (50) internal to said slider (31); a separation element (60) fixed on said hinge body (10) and inserted within said axial blind hole (35) to remain faced to a bottom wall (36) thereto, the slider (31) sliding along said second axis (Y) with respect to said separation element (60); a support rod (16) defining said second axis (Y) having a first end (17′
) reciprocally connected to the bottom wall (12) of said working chamber (11) and a second end (17″
) inserted within said blind hole (35) to connect to said separation element (60); anda counteracting elastic member encompassing said support rod (16) to remain interposed between said bottom wall (12) of said working chamber (11) and said slider (31) to act on said slider (31) to return it from the proximal position to the distal position, wherein said hydraulic circuit (50) includes the blind hole (35) of said slider (31), said separation element (60) dividing the slider in at least one first and one second variable volume compartments (51′
, 51″
) fluidly communicating with each other, said at least one first and one second variable volume compartments (51′
, 51″
) being configured to have at the distal position of said slider (31) respectively a maximum and a minimum volume, andwherein said separation element (60) comprises at least one pass-through opening (53) to put in fluid communication said at least one first variable volume compartment (51′
) and said at least one second variable volume compartment (51″
) and a valve including an obstructing element (64) interacting with said opening (53) to enable a controlled passage of the working fluid between said at least one first compartment and at least one second compartment (51′
, 51″
). - View Dependent Claims (84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97)
