  • Patent number: 7971834
    Abstract: A support stand for a flat-panel display monitor includes a rotatable bracket, a hinge assembly, a base member, a first link bracket, and a second link bracket. The first and second link brackets are rotatably assembled between the rotatable bracket and the support member via the hinge assembly. The rotatable bracket defines a pivot hole, and a guiding notch communicating with the pivot hole. The hinge assembly includes a pivotal shaft, and a positioning washer sleeved on the pivotal shaft. The pivotal shaft is engaged in the pivot hole of the rotatable bracket from the guiding notch. The positioning washer is fixed on the rotatable bracket to prevent the pivotal shaft from disengaging from the pivot hole.

  • Patent number: 7628371
    Abstract: An exemplary adjustable stand (20) for displays includes a main support (22), a movable rack (25), an adjusting system (26) and a balance mechanism (28). The movable rack is slidably mounted on the main support. The adjusting system includes at least one pinion gear (266) rotatably attached on the movable rack and at least one rack gear (267) fixed to the main support. The at least one pinion gear meshes with the at least one rack gear. The balance mechanism is mounted between the main support and the movable rack for balancing gravity of the movable rack and components fixed relative to the movable rack. The present invention further discloses a stand (10) including a support bracket (30), a base (40) and the adjustable stand for connecting the support and the base.
