Patent number: 8490248Abstract: A hinge is mounted between a cover and a body of an electronic device and has an eccentric sleeve and a resisting assembly abutting against each other. When the cover is pivoted, the eccentric sleeve is rotated as well. Because the eccentric sleeve has sectors with varied radiuses, the resisting assembly is compressed to conduct various resisting forces when the eccentric sleeve is rotated. When the cover is opened to a normal visual angle, the hinge provides a constant largest torque. Therefore, the cover is held at the normal visual angle even though the user hits the touch panel on the cover.Type: GrantFiled: June 23, 2010Date of Patent: July 23, 2013Assignee: Shin Zu Shing Co., Ltd.Inventors: Kuan-Chih Chen, Chaio-Liang Tseng, Tzung-Yang Tsai

Publication number: 20120194053Abstract: A hinge is mounted in a sliding assembly for a portable device. The hinge has a hollow pintle, a first positioning ring, a second positioning ring and a resilient element. The positioning rings are mounted around the pintle and respectively have corresponding detents and protrusions to provide positioning function. The resilient element is mounted in the pintle and is mounted between the positioning rings to reduce the length of the hinge. When the second positioning ring is rotated, the second positioning ring also moves upward to lift the supporting panel of the sliding assembly and the cover of the portable device. Therefore, the cover is kept from bumping into the expanding parts of the portable device.Type: ApplicationFiled: February 1, 2011Publication date: August 2, 2012Inventors: Chia-Hao HSU, Yu-Feng Lin, Kuan-Chih Chen, Chia-Chun Yuan, Che-Yu Chou
