<p>A magnetic lock closure device has a first part or magnetically attracting part and a second part or magnetically attracted part, the first part including an annular permanent magnet having a center bore, a first ferromagnetic member formed like a disk plate and attached to one polarity side of the permanent magnet and a nonmagnetic outer cover having a center bore and enclosing the permanent magnet and first ferromagnetic member, and the second part including a second ferromagnetic member formed like a disk plate and adapted to be removably attached to the other polarity side of the permanent magnet. The first and second ferromagnetic members have respective ferromagnetic rods at the center extending therefrom and adapted to meet each other through the center bore when the first and second parts are coupled together. The closure device further has a shape of the permanent magnet and outer cover for accepting the ferromagnetic rod on the second ferromagnetic member and guiding the same into the center bore, and wherein the shape includes a funnel-shaped portion having an outwardly expanded opening extending from the center bore, and a peripheral flat portion extending radially outwardly from said outwardly expanded opening. The second ferromagnetic member may be shaped like a dish having a center bore and adapted to match the shape of the funnel-shaped portion and wherein it has a ferromagnetic rod extending through the center bore of the second ferromagnetic member and secured thereto.</p> |
