Abstract
A self-closing hinge has a housing shaft section with a bore extending therethrough in a direction substantially parallel to a longitudinal axis is attachable to a first rotatable member. A bore extends through the housing shaft section. The cross-sectional profile of the bore in a plane orthogonal to the longitudinal axis has at least one arcuate portion and at least one non-arcuate portion. A roll pin rotatably disposed in the bore has substantially the same cross-sectional profile as the bore. A pair of shaft members, each having a shaft-member body attachable to a second rotatable member, has a pin inserted in an interference fit in the opposed ends of the roll-pin bore. The pins have a cross-sectional profile corresponding to the roll-pin cross-sectional profile.
Claims9
A self-closing hinge for pivotably connecting a first rotatable member to a second rotatable member, the self-closing hinge comprising:
- a housing comprising:
- a housing shaft section having a longitudinal axis, the housing shaft section attachable to the first pivotable member;
- and
- a housing shaft-section bore extending through the housing shaft section in a direction substantially parallel to the longitudinal axis, the housing shaft-section bore having a housing shaft-section bore cross-sectional profile in a plane orthogonal to the longitudinal axis, the housing shaft-section bore cross-sectional profile having at least one arcuate housing shaft-section bore portion and at least one non-arcuate housing shaft-section bore portion;
- a roll pin rotatably disposed in the housing shaft-section bore, the roll pin comprising:
- a roll-pin bore extending through the roll pin in the direction substantially parallel to the longitudinal axis, the roll pin having a roll-pin cross-sectional profile in the plane orthogonal to the longitudinal axis, the roll-pin cross-sectional profile having at least one roll-pin cross-sectional profile arcuate portion and at least one roll-pin cross-sectional profile non-arcuate portion;
- and
- a pair of shaft members, each shaft member of the pair of shaft members comprising:
- a shaft-member body attachable to the second pivotable member;
- and
- a shaft-member pin extending from the shaft-member body and having a shaft-member pin cross sectional profile corresponding to the roll-pin cross-sectional profile,
- wherein the shaft member pin of one shaft member of the pair of shaft members is inserted in an interference fit in a first end of the roll-pin bore and an other shaft member of the pair of shaft members is inserted in an interference fit in a second end of the roll-pin bore.
