Patent number: 7699275Abstract: A stand for a display device is provided. The stand prevents a viewer located at a side of the display from experiencing the problems of a narrow viewing angle by allowing the display device to be pivoted in a wide angle without interference from a wall behind the device. The stand includes a base, a swivel hinge, a fixed unit, a telescopic unit, and a movable unit. The swivel hinge is fixed to the base. The fixed unit is rotatably fixed to the swivel hinge. The telescopic unit includes one member fixed to the fixed unit. The movable unit, to which the other member of the telescopic unit is fixed, is capable of being translated in left and right directions of the base and being rotated.Type: GrantFiled: July 18, 2006Date of Patent: April 20, 2010Assignee: LG Electronics Inc.Inventor: Woon Geun Jang

Patent number: 7694929Abstract: There is provided a stand for a display device. The stand includes a base unit supporting the display device. A main link unit is hinged between the display device and the base unit. A pair of auxiliary links is eccentrically connected to hinges of the main link unit at different positions. A torsion spring includes at least one end connected to the pair of auxiliary links for applying an elastic force to the pair of auxiliary links. The main link unit has a smaller thickness, and thus the size of the stand can be reduced. The stand allows for convenient and smooth operation of the display device. Further, since the spring has a simple structure, the stand can be manufactured through a simple process with less cost. Furthermore, the outer appearance of the stand can be simple.Type: GrantFiled: July 10, 2006Date of Patent: April 13, 2010Assignee: LG Electronics Inc.Inventor: Woon Geun Jang

Patent number: 7677509Abstract: A monitor stand is provided and includes a base, a stand body, a stand top assembly, an upper hinge assembly, a top slide, a first elastic member, and a locking unit. The stand body is supported by the base. The stand top assembly is pivotably supported by the stand body. The upper hinge assembly is provided with a rotating shaft to pivotably connect the stand body to the stand top assembly. The top slide slides along the stand top assembly and has a monitor mounted thereon. The first elastic member is supported on the stand top assembly, to impart an upward elasticity to the top slide. The locking unit restricts a sliding of the top slide with respect to the stand top assembly, when the stand top assembly is pivoted from a vertical position to beyond a predetermined angle.Type: GrantFiled: February 5, 2007Date of Patent: March 16, 2010Assignee: LG Electronics Inc.Inventor: Woon Geun Jang

Patent number: 7458546Abstract: Provided is a monitor stand, capable of preventing an “auto-lift” phenomenon that occurs when a monitor installed thereon is tilted past a predetermined angle, due to a shift in the monitor's weight. The monitor stand includes a base, a stand body, a stand top, a stop slide, a first elastic member, and a one-way clutch assembly. The stand body is supported by the base. The stand top is pivotably supported on the stand body. The top slide slides along the stand top, has a rack extending in a sliding direction fixed thereto, and has a monitor installed thereon. The first elastic member is supported by the stand top, to impart elasticity in an upward direction to the top slide. The one-way clutch assembly is capable of engaging and disengaging to and from the rack, to prevent the rack from rising when engaged to the rack.Type: GrantFiled: February 5, 2007Date of Patent: December 2, 2008Assignee: LG Electronics Inc.Inventor: Woon Geun Jang
