The cam is shaped so that, for any angular position of the cam in its active stroke the centre of rotation of the cam is substantially in the region of a straight line (41) passing through a point (36) of contact between a lateral surface of the cam and a bearing surface of the second element, said straight line being slanted at an angle .phi. identical to the angle of friction in the point of contact. A cam meeting this condition has been found maximize the amplitude of the adjustment without encountering instability.

A further element (31) is secured to at least one of said two elements so as to be pushed by the rotating movement of the hinge to come to rest in correspondence with said space (28). In this way, the space is at least partially obstructed in order to prevent the transversal introduction of slender objects such as fingers.

Abstract: A four-bar linkage hinge comprises two fastening elements (11, 12) with a first (14) and a second link (13) pivoted by their ends, respectively, to each fastening element (11, 12). The first link (14) has an extension (20) which rests on a free arm (25) of a spring (21) which reacts with its other end (24) on one of the two fastening elements, and which exerts pressure on said extension (20) in order to rotate the link to shift the hinge from a nearly closed to a closed position. The arm (25) bears a cam surface with a raised area (28) which is traversed by said extension (20) when the hinge is in the nearly open position, to permit the release of the spring (21) on continuation of the opening movement and push the hinge open.

Disposed between the holes is a seat (17) into which the second element (12) is screwed. The lower part of the second element (12) has a housing (19) into which the first element (11) fits with uniform transverse clearance, thereby advantageously enabling adjustment of the transversal position of the second element (12).

Abstract: A hinge, in particular for furniture doors, of the type in which a wing is designed to be fitted to a base secured to the piece of furniture, comprises an intermediate element for connecting the wing to the base having a substantially U-shaped transverse configuration to determine two rigid sides which laterally embrace the base.The intermediate element is provided with fastening means for securing it to the wing, and unfastenable means connecting it to the base comprising members yieldingly fitted onto the intermediate element in two portions spaced apart from each other in the longitudinal direction of the wing. The yielding members are elastically biased to move into a position in which they engage with complementary housings in the base in order to couple the intermediate element to the latter, the movement of approach between the base and the wing for the coupling being amply indeterminate.
