Patent ID: 6929291

Claim:
A magnetic lock mountable on an electronic device capable of opening or closing, the magnetic lock comprising: a disc shaped, rotatable upper magnetic plate comprising a magnetic member of positive polarity at one half and a magnetic member of negative polarity at the other half; and a circular lower magnetic plate comprising a magnetic member of positive polarity at one half and a magnetic member of negative polarity at the other half, and wherein the upper magnetic plate is formed on an upper housing of the electronic device and the lower magnetic plate is formed on a lower housing of the electronic device so that covering the upper housing on the lower housing will attract the magnetic members of the upper magnetic plate and the magnetic members of the lower magnetic plate having a polarity different from that of the magnetic members of the upper magnetic plate together due to magnetism, thereby fastening the upper and the lower housings together for locking the electronic device; or rotating the upper magnetic plate about 180 degrees will move the magnetic members of the upper magnetic plate with respect to the magnetic members of the lower magnetic plate about 180 degrees to repel the magnetic members of the upper magnetic plate from the magnetic members of the lower magnetic plate having the same polarity as that of the magnetic members of the upper magnetic plate due to magnetism, thereby forming a gap between the upper and the lower housings prior to unlocking the electronic device.
