Patent number: 11733740Abstract: A portable information handling system presents visual images with a flexible display disposed over separate housing portions rotationally coupled by a set of hinges having an opening defined between them. A multi-segmented support couples to the hinges in the opening to dispose a planar surface proximate the flexible display and extend plural parallel members up from the planar support between the hinges, the plural parallel members separating in response to rotation from a flat to a curved orientation.Type: GrantFiled: January 26, 2021Date of Patent: August 22, 2023Assignee: Dell Products L.P.Inventors: Gerald Rene Pelissier, Kevin M. Turchin, John Trevor Morrison, Yung-Fa Cheng

Patent number: 11435786Abstract: A portable information handling system integrates a sliding support with interlaced fingers below a flexible display to adjust support the display based upon rotational orientation of housing portions of the information handling system. In a closed position, the sliding support compresses by fully engaging the fingers so that room is provided over a hinge assembly that rotationally couples the housing to provide folding of the flexible display without wrinkling or compression.Type: GrantFiled: October 5, 2020Date of Patent: September 6, 2022Assignee: Dell Products L.P.Inventors: Gerald Rene Pelissier, Kevin M. Turchin, John Trevor Morrison, Yung-Fa Cheng

Publication number: 20150047152Abstract: A hinge assembly of the present invention includes two parallel axle members, two gears and a transmission member. Each of the axle members has an axis and is rotatable about the axis. The gears are spaced apart from, each other, are mounted respectively and co-rotatably to the axle members, and are disposed on a plane that is perpendicular to the axis of the axle members. The transmission member is rotatable about a transmission axis that is perpendicular to and coplanar with the axes or the axle members, and meshes with the gears such that when one of the axle members rotates, the other one of the axle members is driven to rotate via the gears and the transmission member.Type: ApplicationFiled: March 24, 2014Publication date: February 19, 2015Applicant: I3G DESIGN CO., LTD.Inventor: Yung-Fa CHENG

Patent number: 8411055Abstract: A portable electronic device includes a main body including a housing, a display electrically connected to the main body, and a frame for connecting between the main body and the display. The display includes a display panel and a carrier for carrying the display panel. The portable electronic device is capable of being operated to switch between a closed state and an open state. When the portable electronic device is in the closed state, the display covers the main body with either one of the display panel or the carrier facing the housing of the main body, and the main body and the display are surrounded by the frame. When the portable electronic device is in the open state, the main body is straddled by the frame and is supported by the frame to define a first predetermined angle between the main body and the frame.Type: GrantFiled: April 27, 2010Date of Patent: April 2, 2013Assignee: Hon Hai Precision Industry Co., Ltd.Inventors: Yung-Fa Cheng, Hsiang-Lung Kao
