Patent ID: 8823477

Claim:
A shielded magnetic attachment apparatus having engaged and disengaged configurations, comprising: at least one magnet, a first casing comprising ferromagnetic material attached to one side of the at least one magnet and the first casing having a first and second portion and wherein the second portion of the first casing is on another side of the at least one magnet and wherein the second portion of the first casing is non-ferromagnetic, a second casing comprising ferromagnetic material operably magnetically attachable to the at least one magnet, and a release mechanism attached to either the first or second casing for transitioning the shielded magnetic attachment apparatus from the engaged to the disengaged configuration, wherein the shielded magnetic attachment apparatus is in the engaged configuration when the at least one magnet provides a magnetic force which acts to keep the shielded magnetic attachment apparatus in the engaged configuration, and the shielded magnetic attachment apparatus is in the disengaged configuration when the second portion of the first casing is spaced from the at least one magnet such that there is an air gap between the second portion of the first casing and the at least one magnet.
