Rotatable bipolar phased magnetic locking system for door

摘要

A magnetic entry system utilizes opposing polar magnets. At least one of the magnets is rotatable between a first position in which poles of the magnets attract and a second position in which poles of the magnets repel. The magnets are positioned with respect to one another such that the magnets must be pulled apart along a line of travel that is generally normal to planar opposing surfaces of the mangets.
