Patent number: 6918159Abstract: A hinge apparatus disposes a panel to be opened and closed with respect to a body of an appliance. The hinge apparatus includes a fixing bracket fixed on the body, a supporting bracket fixed on the panel and a hinge shaft fixed on the fixing bracket to rotatably support the supporting bracket. The hinge apparatus also includes an automatic pivot unit to cause the panel to be opened with respect to the body by a predetermined free rotation angle when a locking state between the panel and the body is released. Further, the hinge apparatus includes a manual pivot unit to provide a frictional force between the supporting bracket and the hinge shaft. The frictional force restricts the supporting bracket from being automatically rotated by the automatic pivot unit and also fixes the panel, which is opened further from the predetermined free rotation angle, in a fixed position.Type: GrantFiled: August 20, 2002Date of Patent: July 19, 2005Assignee: Samsung Electronics Co., Ltd.Inventor: Kang-ho Choi
