ABSTRACT:
A magnetic fastening device with discrete slidable adjustments, comprising first and second sheets, each having a plurality of magnetic section elements with first and second poles disposed in alternating groups defining predetermined abutting patterns. The magnetic section elements are abuttingly disposed in two groups. In one group, the elements' magnetic field is disposed in one direction perpendicular to the sheets. In the other group, the elements' field is disposed in the opposite direction. The groups repeat themselves in an alternating pattern. The movement of the first and second sheets is constrained to keep them in an abutting relationship with respect to each other over a predetermined path over the first and second sheets, thereby permitting the sheets to be slidably movable along a predetermined distance relative to each other in discrete steps that overcome the attraction and repulsion forces of the magnetic section elements upon the application of a pulling force of a predetermined magnitude.
