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) betw

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.

The invention claimed is: 1. A hinge structure coupling a door to a frame and comprising:a first stationary element;a first movable element configured to cause a door to rotate about a longitudinal axis between an open door position and a closed door position, the first movable element being pivotally mounted onto the first stationary element;closing means acting on the first movable element to automatically return the door to the closed position upon opening thereof; andhydraulic damping means acting on the first movable element to oppose and damp a closing movement of the closing means;a first operating chamber housing the closing means and the hydraulic damping means,wherein the closing means comprise a first cam element having a first contact surface, and a first plunger element movable within the first operating chamber along a transverse axis between a compressed end position, corresponding to the open door position, and an extended end position, corresponding to the closed door position, the plunger element having a front face which is adapted to engage the first contact surface of the cam element,wherein the closing means comprise first counteracting elastic means operating on the first plunger element and urging the front face against the first contact surface of the first cam element, andwherein the first plunger element has a side wall and an end wall defining the front face, the end wall being designed to separate the first operating chamber into a first variable volume compartment and a second variable volume compartment which are in fluid communication with each other, the first counteracting elastic means being located in the first compartment.
