A hinge for cold rooms, swing gates or the like, which comprise a stationary support structure (S) and at least a door (A) movable between an open door position and a closed door position. The hinge comprises a box-like hinge body (3) and a pin (5) reciprocally rotatably coupled to rotate about a first axis (X) between the open door position and the closed door position. Closing means are provided (10) for automatically returning the door (A), as well as a working fluid acting thereon to hydraulically contrast their action. The closing means (10) comprise a cam element (11 ) unitary with said pin (5) interacting with a plunger element (12) housed in an operating chamber (25) defined within the box-like hinge body (3). The box-like hinge body (3) has an elongated shape to define a second axis (Y) perpendicular to the first one (X).

A hinge structure (1) for self-closing doors or the like comprises a first stationary element (2) attachable to the frame (T) of a door (P), a first movable element (3) securable to the door (P) and pivotally mounted to the first stationary element (2) for rotating about a longitudinal axis (X) between an open door position and a closed door position. The structure (1) further comprises closing means (4) acting on the first movable element (3) for automatically returning the door (P) to the closed position during opening, hydraulic damping means (5) operating on the first movable element (3) to oppose and damp the movement produced by the closing means (4). The closing means (4) and the hydraulic damping means (5) are housed within a first operating chamber (6) locate internally of the first stationary element (2). An assembly incorporates such hinge structure.
