ABSTRACT:
The present magnetic closure device has one or more holding members and one or more closure members, each with a surface configuration providing an increased frictional force, when two matching surface configurations cooperate. One member is made of permanent magnetic material, while the other member is made of ferromagnetically soft material. The increased frictional force and the magnetic force combine to provide an effective closure device for articles of non-magnetic material, such as leather goods, textiles, and synthetic materials.
