Abstract
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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
56 words
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;
Claim 2
Dependent Claim
56 words
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;
Claim 3
Dependent Claim
79 words
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.
Claim 4
Dependent Claim
79 words
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.
Claim 5
Dependent Claim
34 words
A self-closing hinge-mechanism as defined in claim 1 further comprising: said roller means and the location of engagement of the spring means with said bellcrank being spaced equidistant from the pivot for said bellcrank.
Claim 6
Dependent Claim
33 words
A self-closing hinge mechanism as defined in claim 1 further comprising: said spring means being disposed within the fixed portion at a location between said bellcrank and said pivot for said cam means.
Claim 7
Dependent Claim
32 words
A self-closing hinge mechanism as defined in claim 1 further comprising: said cam means having a constant radius arc throughout its range of travel corresponding to the open position of the hinge.
Claim 8
Dependent Claim
48 words
A self-closing hinge mechanism as defined in claim 1 further comprising: said fixed member including an internal recess formed therein to receive and engage one end of the spring; and said bellcrank including finger means at its spring-engaged end to be received in an end of said spring.
Claim 9
Dependent Claim
40 words
A self-closing hinge mechanism as defined in claim 1 further comprising: said first link having a pair of transversely spaced, identical cams; and said roller means including a pair of rollers, each being located to engage one of the cams.
Claim 10
Dependent Claim
20 words
A self-closing hinge mechanism as defined in claim 6 further comprising: said spring means being located transversely between said cams.
