  • Publication number: 20120102675
    Abstract: A torque-adjustable hinge is mounted between a display panel and a base of a portable device and has a stationary bracket, a rotating bracket, a pintle, a torsional spring and an adjusting element. The stationary bracket is attached to the base. The rotating bracket is attached to the display panel. The pintle is attached to the rotating bracket and is mounted through the torsional spring. The torsional spring is attached to the stationary bracket and abuts against the adjusting element. By changing the height that the adjusting element protrudes above a receiving tag of the stationary bracket, the torsional spring is selectively tighter or looser wound around the pintle. Therefore, the torque generated by the hinge is adjusted without replacing any element.

  • Patent number: 7921516
    Abstract: A hinge assembly has two tracks, a main bracket, at least one connecting bracket, at least one sliding hinge and at least one tilting hinge. The main bracket is mounted slidably between the tracks. The connecting bracket is mounted securely on the main bracket. The sliding hinge corresponds to and selectively holds the connecting bracket. The tilting hinge is connecting to the main bracket. With the related movement between the connecting bracket and the sliding hinge, the connecting bracket is selectively held or moved. Therefore, a moving bracket of a frame for an electronic device being attached to the tilting hinge is selectively pushed and held in a body of the frame or received in the body.

  • Patent number: 7861377
    Abstract: An abrasion-enhanced hinge has a pintle, a washer assembly and a stationary leaf. The pintle is connected securely to a cover of an electronic device. The washer assembly has multiple stationary washers and multiple rotating washers. The stationary and rotating washers are mounted interlacedly around the pintle. The stationary washers are connected securely to each other. The rotating washers are connected securely to the pintle. The stationary leaf is connected securely to a base of the electronic device and is connected securely to the nearest stationary washer. When the cover is pivoted to the base, the pintle is rotated relative to the stationary leaf. Thus, the rotating washers are rotated relative to the stationary washers. Because the stationary and rotating washers are mounted interlacedly, the rotations between the stationary and rotating washers provide a lot of abrasions. Therefore, the hinge provides enhanced abrasion.

  • Patent number: 7752712
    Abstract: A hinge is mounted between a base and a screen of an electrical device and has a base panel, a guiding panel and a connecting member. The base panel is attached to the base and has a front surface. The guiding panel is mounted slidably on the front surface of the base panel and has a front surface and an arced slot. The connecting member is mounted slidably on the front surface of the guiding panel, is mounted securely on the screen panel and slides along the arced slot when in operation to allow users to slide and rotate the screen relative to the base.

  • Publication number: 20090145337
    Abstract: A slidable hinge has a stationary leaf and a sliding leaf being respectively mounted to a base and a cover of a portable electronic device. The stationary leaf has at least two guiding grooves singularly formed substantially perpendicularly therethrough in a curved manner. The sliding leaf has at least two guiding elements slidably mounted respectively in the guiding grooves of the stationary leaf. With the guiding elements sliding along the guiding grooves, the sliding leaf slidably rotates relative to the stationary leaf to a perpendicular angle relative to the stationary leaf. Therefore, the portable electronic device as a whole presents a novel posture for adapting developed functions or programs.

  • Publication number: 20090106935
    Abstract: A hinge with an elevating function is mounted between a top panel and a bottom panel of an expansion pad and has a lower pivot bracket assembly, a pivoting arm assembly, an upper pivot bracket assembly and a top pivoting assembly. The lower pivot bracket assembly is mounted securely on the bottom panel. The pivoting arm assembly has an upper end and a lower end. The lower end of the pivoting arm assembly is mounted pivotally on the lower pivot bracket assembly. The upper pivot bracket assembly is mounted pivotally on the upper end of the pivoting arm assembly. The top pivoting assembly is attached securely to the top panel and is mounted pivotally on the upper pivot bracket assembly to allow the top panel to be moved up and down and to be pivoted relative to the bottom panel. Consequently, the operating height and angle are adjustable.
