Magnetic hinge apparatus
First Claim
1. A magnetic hinge apparatus, maintained at a first stable equilibrium or at a second stable equilibrium, comprising:
- a hinge housing having a cavity;
a hinge shaft situated inside the cavity;
an immobilized magnetic device assembled inside the hinge housing and situated inside the cavity; and
a rotatable magnetic device fixed with the hinge shaft inside the cavity and rotatable to the immobilized magnetic device, the rotatable magnetic device being disposed with the immobilized magnetic device as mates, the opposite surfaces of the rotatable magnetic device and the immobilized magnetic device having the same polarity, wherein the rotatable magnetic device is positioned at one side adjacent to the immobilized magnetic device when the magnetic hinge apparatus is maintained at the first stable equilibrium, and the rotatable magnetic device is positioned at the other side adjacent to the immobilized magnetic device when the magnetic hinge apparatus is maintained at the second stable equilibrium.

Abstract
A magnetic hinge apparatus having a hinge housing, a hinge shaft, an immobilized magnetic device, and a rotatable magnetic device is disclosed. The hinge housing has a cavity for receiving the immobilized magnetic device and the rotatable magnetic device. There is no relative motion between the immobilized magnetic device and the hinge housing, due to the firm attachment of the immobilized magnetic device to the hinge housing. The hinge shaft on which the rotatable magnetic device is assembled is inserted in the cavity. When the hinge housing rotates around the hinge shaft, the immobilized magnetic device is simultaneously rotated relatively to the rotatable magnetic device. The rotatable and immobilized magnetic devices are disposed as mates, and the opposite surfaces of the rotatable magnetic device and the immobilized magnetic device have the same polarity. Accordingly, the magnetic hinge apparatus is stably maintained at two equilibrium positions. When the magnetic hinge apparatus is maintained at the first stable equilibrium, the rotatable magnetic device is positioned at one side adjacent to the immobilized magnetic device. When the magnetic hinge apparatus is maintained at the second stable equilibrium, the rotatable magnetic device is positioned at the other side adjacent to the immobilized magnetic device.
