  • Patent number: 5477443
    Abstract: A lamp assembly is disclosed which includes a base, a lamp arm mounting adapter on the base for pivotally mounting a lamp arm thereto, with the lamp arm itself having a first pair of hollow support tubes mounted on the adapter for pivotal movement on a vertical axis in a generally horizontal plane and having a arm support pivotally mounted on their opposite ends for pivotal movement on a vertical axis on a horizontal plane. A second pair of arms having inner and outer ends are pivotally mounted on their inner ends to the arm support for pivotal movement about a horizontal axis in a vertical plane. A counterbalance spring is connected between the arm support and the second pair of arms and a lamp head is pivotally connected on the outer end of the second pair of arms for pivotal movement at least about a horizontal axis in a vertical plane.

  • Patent number: 5097400
    Abstract: A spring balanced lamp is disclosed which includes a base, a lamp arm support pivotally connected to the base, a first pair of hollow tubular arms pivotally connected at one end to the arm support and at their opposite ends to a second pair of hollow tubular arms. At least one counterbalance spring is connected to the arms to maintain the arms in a plurality of stable upright positions to which they may be moved. A lamp head assembly is pivotally connected to the second pair of arms and includes a support neck pivotally connected to the arms and a support ring pivotally mounted on the neck for rotation on an axis which is generally perpendicular to the axis of the pivotal connection of the neck to the arms. A perforated reflector and a translucent shade are mounted on the ring of the reflector.
