Abstract
A self-closing hinge consisting of a device inserted in the fixed fitting of the hinge and achieving the kinematic diagram of a linked and deformable quadrilateral. The hinge consists of a fixed fitting and of a movable fitting connected to each other by two tumblers which constitute with the latter the sides of the linked and deformable quadrilateral. One of the tumblers carries cams on which a spring at least applies through a bent lever and at least a roller.
Claims7
A self-closing hinge mechanism having a fixed portion adapted to be mounted to a fixed member and a movable portion adapted to be mounted to a movable member for movement therewith comprising:
- a pair of links, each pivotally connected by points to each of the fixed portion and movable portion to define a quadrilateral link mechanism;
- a first of said links including cam means extending from that end of the first link which is adjacent its pivot to the fixed member;
- a bellcrank pivotally mounted at a point between its ends to the fixed member;
- roller means rotatably carried by one end of the bellcrank;
- spring means in engagement with the other end of the bellcrank to bias the bellcrank in a direction which will cause engagement of the roller means with the cam means.
