An interlocking magnetic snap fastener of simplified construction for use with garments is provided. The magnet fastener comprises two mating, magnetically attracted elements of minimal thickness. A central recess in a first element (6) containing a magnet or ferromagnetic disk provides entry and engagement for an opposing magnet protruding from a. second element (8). When the second element is placed in close proximity to the recess, a magnetic force field is generated between magnets, or alternatively, between the ferromagnetic disk of the first element and the protruding magnet of the second element and the magnet in the second element is induced to slide sideways, enter the recess of the first element and assume automatically-aligned contact with its counterpart Engagement within the recess prevents lateral movement between, and disengagement of the first and second elements. |

1. A magnetic fastener for securing two pieces of sheet material together, the magnetic fastener comprising:
a receiving element for affixing to a first sheet of material, the receiving element having a front face, a rear face and a central opening in the front face of the receiving element, the receiving element further including a first planar magnet recessed within the central opening on the front face of the receiving element creating a recessed opening in the central opening; an insertion element for affixing to a second sheet of material, the insertion element having a front face and a rear face, the insertion element having a second planar magnet, oriented in opposite polarity to that of the first planar magnet and affixed and protruding from a central portion of the front face of the insertion element, where the second planar magnet is sized to fit within the recessed opening in the central opening on the front face of the receiving element, such that when the second planar magnet is in proximity to the recessed opening in the central opening of the receiving element, the magnet of the insertion element is induced to enter and substantially fill the recessed opening of the receiving element, securing the two elements together through the magnetic attraction between the first planar magnet and the second planar magnet, where the areas on the receiving element and the insertion element surrounding the first magnet and second magnet are nonmagnetic, and where the recessed opening in the receiving element substantially the same depth as the distance that the second planar magnet protrudes from the front face of the insertion element, whereby the front face of the receiving element and the front face of the insertion element are brought into direct contact with one another, creating closure of the first and second sheets of material. |
