A crosslink over-center hinge having a supporting wall member and a door member which are joined together by a crosslink mechanism formed by two linkage arms coupled pivotingly together in their middle area, the end of one linkage arm being directly journaled on the supporting wall member and one end of the other being directly journaled on the door member, the other end in each case being coupled to the other hinge member for guidance on a curve in space. The hinge having an over-center mechanism is provided with a closing spring, which mechanism resiliently urges the hinge to the hinge end position at least in the vicinity of the closed position. A link connecting the door member to one linkage arm is so formed that its middle area is situated, when the hinge is in the closed position, in the vicinity of the pivot shaft pivotingly coupling the linkage arms, while the over-center mechanism is disposed on or in this link and has an elongated over-center element pivotingly mounted on the pivot shaft of the link in the door member with a locking surface engaging the linkage arm pivot shaft in range of the hinge-closed position. The over-center element is biased by the closing spring supported in the area of the other end of the link towards an engagement of its locking surface with the linkage arm pivot shaft. |
