Patent number: 7925318Abstract: A slide type portable terminal can include a main unit including separated first and second key sections and a first plate coupled to a surface of the main unit and a display unit with a display screen on a front surface and a second plate. The second plate can slide with respect to the first plate and preferably slides along the surface of the main unit to cause the first and second key sections of the main unit to be covered and exposed by the display unit. Further, first and second magnets can be provided on the first and second plates, respectively, so that the same poles of the magnets face each other to provide a repulsive force when they are positioned to face close to each other. According to embodiments of the present invention, there are various advantages in that the portable terminal can be utilized more conveniently and production costs and failure rates thereof can also be reduced.Type: GrantFiled: January 27, 2010Date of Patent: April 12, 2011Assignee: LG Electronics Inc.Inventors: Sang-Hyuk Im, Hyun-Ho Lee, Chang-Il Lee, Kwon-Jin Kang, Red-Heat Oh, Ji-Sung Park

Patent number: 7565185Abstract: Disclosed herein is a three-axial rotation type mobile communication terminal. The mobile communication terminal includes a body part, a folder part disposed on the body part in the thickness-wise direction of the body part, and a hinge unit. The hinge unit includes a first hinge part mounted at one corner of the body part such that the first hinge part can be rotated relative to the body part about a rotation axis arranged in the thickness-wise direction of the body part, a second hinge part mounted at the top of the first hinge part such that the second hinge part can be hingedly rotated relative to the first hinge part about a hinged rotation axis arranged perpendicular to the rotation axis of the first hinge part, and a third hinge part having one end coupled to the second hinge part such that the third hinge part can be rotated relative to the second hinge part about a rotation axis perpendicular to the hinged rotation axis of the second hinge part and the other end coupled to the folder part.Type: GrantFiled: January 11, 2006Date of Patent: July 21, 2009Assignee: LG Electronics Inc.Inventors: Kwon Jin Kang, Jung-Ohn Yim

Patent number: 7356881Abstract: A swivel hinge can have a first hinge section and a second hinge section coupled to the first hinge section to rotate in a direction perpendicular to the first hinge section. The first and second hinge sections can include first and second magnets configured to relatively position the first and second hinge sections with respect to each other. The swivel can include a stopper engagement section provided at one end of a second hinge shaft to rotate together with the second hinge shaft and a stopper having a surface facing a locking surface of the stopper engagement section to restrict rotation of the second hinge section. The stopper can allow the locking surface of the stopper engagement section to freely rotate when the first hinge section rotates by a predetermined angle. The swivel hinge can operate in a portable terminal.Type: GrantFiled: February 24, 2004Date of Patent: April 15, 2008Assignee: LG Electronics Inc.Inventors: Ji-Sung Park, Red-Heat Oh, Sang-Hyuk Im, Kwon-Jin Kang
