Abstract
A fastener assembly is adapted to engage components for rotation with respect to one another. The fastener assembly includes a support contacting one of the components and a fastener contacting the other one of the components. A body of the fastener extends through apertures defined in the components and in the support. An end portion of the body of the fastener is deformed radially outwardly into engagement with the support. The fastener engages the components and the support upon deformation with sufficient compression along a pivot axis to resist unintended rotation of the components with respect to one another and to permit intended rotation of the components.
Claims27
A fastener assembly adapted to engage components for rotation with respect to one another, said fastener assembly comprising:
- adjacent components each defining an aperture extending therethrough along a pivot axis;
- a polymeric support positioned at least partially within the aperture of at least one of said adjacent components, said support defining an aperture extending therethrough along said pivot axis in substantially concentric management with said apertures of said adjacent components, said support comprising a flange extending radially outwardly with respect to said pivot axis and contacting one of said adjacent components;
- and
- a fastener having a body extending along said pivot axis and through said apertures defined in said adjacent components and said support, an end portion of said body extending beyond said support, said body of said fastener having a cross section sized to permit insertion through said aperture defined in said support, and said end portion of said body of said fastener being deformed radially outwardly into engagement with said support upon said insertion to a cross section sized to prevent removal of said end portion through said aperture defined in said support;
- said fastener engaging said adjacent components and,said support upon said deformation with sufficient compression in a direction along said pivot axis to resist unintended rotation of said adjacent components with respect to one another about said pivot axis and to permit intended rotation of said adjacent components with respect to one another.

A method for engaging components for rotation with respect to one another about a pivot axis, said method comprising the steps of:
- (a) positioning the components in contact with one another such that an aperture extending through each of the components is oriented along the pivot axis;
- (b) positioning a support at least partially within at least one of the adjacent components with the aperture of the support in substantially concentric arrangement with the apertures of the adjacent components and a flange of the support adjacent one of the components;
- (c) inserting a body of a fastener through the apertures of the adjacent components and the support and extending an end portion of the body of the fastener beyond the support;
- (d) deforming the end portion of the body of the fastener radially outwardly into engagement with the support;
- and
- (e) generating a compressive force between the flange of the support and the adjacent components in a direction along the pivot axis, thereby resisting rotational movement of the adjacent components with respect to one another and permitting intended rotation of the adjacent components with respect to one another.
