Novelty: Hydraulic door hinge mechanism characterised by controlled three-stage closure course (0 deg., 90 deg., from 0 to 90 deg., and from +90 deg. to +180deg.). Constitution: A central axle (2) having a groove enabling the sliding of a twin wedge (14), and an internal motion dampener (1) furnished with a cap-dampener (12), a twin wedge (4) and a compression spring (3) furnished with the cap-stopper (11); furthermore, said central mechanism (2) bears outside a first reciprocating ring (7), and a second rotary ring (8) adequately adapted to a fixing stem (10) so that through reciprocation said spring can be mono-axially contracted while the returning door is smoothly closed up by the hydraulic dampener. |
