Abstract
A hinge mechanism including a sleeve member having an inwardly facing bearing surface and a rod member dimensioned to fit in the sleeve member in engagement with the bearing surface. The sleeve member is resiliently flexible but substantially inextensible and has at least one recess formed in its bearing surface, the rod member being provided with a projection shaped to be engageable in the recess. The rod member is an interference fit in the sleeve member with the projection located in the recess and the rod member is rotatable in the sleeve member by causing only resilient deformation of the latter.
Claims16
A hinge mechanism comprising a sleeve member defining an inwardly facing bearing surface and a rod member dimensioned to fit in the sleeve member in direct engagement with the bearing surface wherein:
- the sleeve member is resiliently flexible but substantially inextensible, at least one recess is formed in the bearing surface, the rod member is provided with a projection shaped to be engageable in the recess;
- said rod member being an interference fit in and in direct engagement with the sleeve member with the projection located in the recess, and rotatable in the sleeve member by causing only resilient deformation of the latter;
- and the shape into which the sleeve member is distorted varies when said sleeve member is rotated with respect to said rod member from any first position to any second position to thereby positively distort different areas of the sleeve member while previously distorted areas of the sleeve member return to a substantially undistorted condition as the sleeve member is rotated from any first position to any second position.
A vehicle sun visor including a hinge mechanism comprising a sleeve member defining an inwardly facing bearing surface and a rod member dimensioned to fit in the sleeve member in direct engagement with the bearing surface wherein;
- the sleeve member is resiliently flexible but substantially inextensible, at least one recess is formed in the bearing surface, the rod member is provided with a projection shaped to be enagageable in the recess;
- said rod member being an interference fit in and in direct engagement with the sleeve member with the projection located in the recess, and rotatable in the sleeve member by causing only resilient deformation of the latter;
- and the shape into which the sleeve member is distorted varies when said sleeve member is rotated with respect to said rod member from any first position to any second position to thereby positively distort different areas of the sleeve member while previously distorted areas of the sleeve member return to a substantially undistorted condition as the sleeve member is rotated from any first position to any second position.
