Patent ID: 7089627

Claim:
A magnetic hinge defining a hinge axis, comprising: a. a first hinge plate of non-magnetic material; b. at least one first magnet disposed in said first plate adjacent the hinge axis for movement therewith; c. a second hinge plate of non-magnetic material; and d. at least one second magnet disposed in said second plate adjacent the hinge axis for movement therewith; said first and second plates being movable about the hinge axis between: i. a closed orientation wherein said first and second plates are generally parallel and at least partially overlapping, and said first and second magnets are generally parallel, overlapping and in the same magnetic orientation, and ii. an open orientation wherein said first and second plates are generally parallel and at least partially non-overlapping, and said first and second magnets are generally parallel, non-overlapping and in opposite magnetic orientations, said first and second magnets being coplanar and aligned along a common axis; wherein at least one of said first and second plates incorporates means for precluding relative sliding movement thereof parallel to the hinge axis.
