Patent number: 9398707Abstract: An expansion platform is disclosed. The expansion platform includes a main body, a moving element, a first elastic element, and a positioning device. The moving element moveably combines with the main body and includes at least one fixed element and a sliding slot. The positioning device includes a second elastic element and a positioning element connected to the main body and passing through the sliding slot. The positioning element is pressed by the insertion of the portable electronic apparatus to be removed from a fixed state between the positioning element and the sliding slot, and the moving element is moved to fix the portable electronic apparatus. When the moving element moves reversely to an unlocked position, the portable electronic apparatus detaches from the main body, and the positioning element moves to an initial position and then is fixed by the sliding slot to stop the moving element.Type: GrantFiled: July 11, 2013Date of Patent: July 19, 2016Assignee: WISTRON CORPORATIONInventors: Fang-Ta Chang, Lee Hua Yu

Patent number: 9360950Abstract: A key control device for a click pad is provided that includes a first driving member, a second driving member, a first connecting rod, and a second connecting rod. When the first driving member is pressed, it drives the first connecting rod for activating the key functions of the click pad. When the second driving member is pressed, it drives the second connecting rod and drives the first driving member to drive the first connecting rod to recover to the original position for shutting down the key functions of the click pad. The key control device controls the activation or shutdown of the key functions of the click pad. Because the key control device is hidden below a click pad of a notebook computer, the appearance of an electronic device is not effected.Type: GrantFiled: September 13, 2012Date of Patent: June 7, 2016Assignee: Wistron CorporationInventor: Fang-Ta Chang

Patent number: 9025322Abstract: The present disclosure relates to a key control device for click pad. The key control device is disposed below a click pad of a notebook computer, and comprises a frame and a sliding lever. The click pad is disposed at the frame. When a plurality of positioning parts of the sliding lever are interlocked with a plurality of locking parts of the frame, the frame and the click pad cannot have up-and-down movements and thus shutting down the key functions of the click pad. When the plurality of positioning parts of the sliding lever are not interlocked with the plurality of locking parts of the frame, the frame and the click pad can have up-and-down movements and thus activating the key functions of the click pad. Thereby, the key control device according to the present disclosure can control the activation or shutdown of the key functions of the click pad.Type: GrantFiled: March 15, 2013Date of Patent: May 5, 2015Assignee: Wistron CorporationInventor: Fang-Ta Chang

Patent number: 8305753Abstract: An electronic device includes an adjustable mechanism disposed at a front end of a housing body thereof. The adjustable mechanism includes a foot pad extending through the housing body, and movable relative thereto between a retracted position, where a bottom of the foot pad is higher than that of a docking station, and an extended position, where the bottom of the foot pad is at a same level as that of the docking station. A movable engaging hook is mounted slidably on an inner side of the housing body, and is partially exposed from the housing body. The engaging hook engages the foot pad when the engaging hook is at a limiting position and when the foot pad is at the retracted or extended position, and disengages the foot pad to enable the foot pad to move between the retracted and extended positions when at a free position.Type: GrantFiled: January 21, 2010Date of Patent: November 6, 2012Assignee: Wistron CorporationInventor: Fang-Ta Chang
