Abstract
An example hinge includes a hinge pin extending along an axis and a first knuckle for receiving the hinge pin. The first knuckle is rotatable about the axis. A second knuckle for receiving the hinge pin and is rotatable about the axis. At least one bearing limits relative rotation between the first hinge knuckle and the hinge pin. The example hinge assembly may include a tolerance ring between the hinge pin and the first knuckle to urge the bearing away from the axis. An example method of producing a hinge includes the steps of permitting a first hinge plate to move relative a hinge pin and limiting movement of a second hinge plate relative a hinge pin. The method biases a bearing adjacent the hinge pin to limit movement of the second hinge plate relative the hinge pin.
Claims24
A hinge, comprising:
- a hinge pin extending along an axis;
- a first hinge plate including a first knuckle receiving said hinge pin and rotatable about said axis;
- a second hinge plate including a second knuckle receiving said hinge pin and rotatable about said axis;
- and
- at least one first bearing disposed between said first knuckle and said hinge pin for limiting relative rotation between said first knuckle and said hinge pin.
An bearing arrangement for hinge components, comprising:
- a bearing mountable around a hinge pin that extends along a rotational axis;
- and
- a biasing member for biasing a bearing surface to limit relative rotational movement between said hinge pin and a hinge knuckle about said rotational axis.
A method of arranging a hinge assembly, comprising the steps of:
- (a) permitting a first hinge plate to move relative a hinge pin about an axis;
- (b) limiting movement of a second hinge plate relative the hinge pin;
- and
- (c) biasing a bearing adjacent the hinge pin to limit movement of the second hinge plate relative the hinge pin.
