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.

Abstract: An adjustable baseball or sports type hat is disclosed having an adjustable circumferential portion along the bottom of the crown. A visor may be attached to the front or rear portion of the crown. A pair of adjustment clasps are affixed near each temple of the crown at or near where the visor is attached to the crown to alter the size of the circumferential portion of the crown. The adjustment clasps may be hidden when adjusted for the wearer or they may be attached on the exterior of the crown. In one embodiment the adjustment clasp is formed by a flap, which is formed above the temple of the crown where the edge of the visor attaches to the crown and has Velcro® on its underside which mates with Velcro® attached on the temple portion of the crown. The flap may be of any shape including that of a logo or trademark. A trademark or logo may also be affixed to the flap.

Abstract: An adjustable baseball or sports type hat is disclosed having an adjustable circumferential portion along the bottom of the crown. A visor may be attached to the front portion of the crown. At least two, but eventually four, two-part adjustment clasps are affixed near each temple of the crown to alter the size of the circumferential portion of the crown. Preferably, the adjustment clasps are hidden when adjusted for the wearer. This is accomplished by embedding one part of the adjustment clasp in or from a detachable flap, which can be created by leaving a part of adjacent triangular sections unsewn. The other part of the clasp is attached to the adjacent crown section, near the visor zone or front.
