Patent ID: 8402612

Claim:
A dual magnetic interlocking pin system for attaching an item comprising: a. a chamber having an opening, at least a bottom wall, a side wall having a side wall top and wherein the side wall is connected to the bottom wall opposite the side wall top; b. a magnetically attractable inner plate fixed within the chamber adjacent the bottom wall; c. a free moving magnet with a first magnet flat side and a second magnet flat side opposite the first magnet flat side, wherein the free moving magnet is disposed in the chamber for moving between the opening and the magnetically attractable inner plate, wherein the free moving magnet is not removable from the chamber, and wherein the free moving magnet provides a magnetic field with a first field size; d. a first outer plate secured to the side wall top having a thickness and magnetic attraction strong enough to movably hold the free moving magnet adjacent the first outer plate; and e. an engagement pin comprising: (i) a pin head; (ii) a pin stem connected to the pin head, and wherein the pin stem has a diameter small enough to slidably move inside the chamber and the pin stem comprises a magnetically attractable material capable of moving the free moving magnet from a position adjacent the magnetically attractable inner plate to a position adjacent the first outer plate, wherein the pin stem moves relative to the opening, and wherein the pin stem is selectively removable from the chamber; and (iii) wherein when the pin stem is inside the chamber the free moving magnet moves to engage the magnetically attractable inner plate.
