  • Patent number: 6832100
    Abstract: A magnetic hinge apparatus is applicable to a foldable product (such as folding cellular phone) for connecting the cover and the base. A practical application is provided by aligning two magnetic cams on a shaft. One magnetic cam is connected to the base, and the other is connected to the cover. Also, an attractive force is formed between the opposite surfaces of the two opposite magnetic cams. Before applying any external force on the foldable product, the convex portion of one magnetic cam completely engages the concave portion of the other magnetic cam. When the cover is opened, both magnetic cams are rotated relatively and then separated from the engaged position. When the cover keeps in opening, the convex portions of both magnetic cams are going to touch and then across each other; meanwhile, the magnetic force can attract two magnetic cams back to the engaged position. Accordingly, the foldable product secured by the magnetic hinge apparatus possesses the snap characteristic.

  • Patent number: 6630878
    Abstract: A magnetic rotating apparatus is used for connecting a body portion and a rotating portion of a foldable product. The body portion has an assembling portion while the rotating portion has a pivot portion. The rotating portion is secured to the body portion by engaging the pivot portion with the assembling portion, so that the rotating portion is allowed to pivot on the body portion and be positioned at the first stable equilibrium or the second stable equilibrium. The magnetic rotating apparatus comprises a magnetic body component situated in the assembling portion and a magnetic pivot component situated in the pivot portion. The magnetic body component and the magnetic pivot component are disposed as mates. Also, the opposite surfaces of the magnetic pivot component and the magnetic body component have the same polarity. When the rotating portion and the body portion are maintained at the first stable equilibrium, the magnetic pivot component is positioned at one side adjacent to the magnetic body component.

  • Publication number: 20030179880
    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.
