  • Patent number: 6056361
    Abstract: An articulated support chair has a frame, a seat cantilevered from the frame, and a back hanging from the frame, with a lower end of the back hinged to an underside of the seat. A lumbar support extends from the seat and pivots to maintain supporting contact as the angles of the seat and back change under varying load conditions. In further embodiments, arm rests may be rigidly coupled below the seat to the back, and a fold-down tablet may be affixed to the frame at one side of the seat. Wedge units assemble in a modular fashion to define straight or different curved or bent rows for waiting room, conference room, or auditorium/theater installations and provide side tables, lockable cabinets, or utility and light bays between adjacent seats. A task chair, a side chair, and tandem chair embodiments are described.

  • 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.

  • Patent number: 4858807
    Abstract: A device for cutting sheet material wound in a cylindrical roll includes a blade member having a cutting edge extending the length thereof, and positioning means extending from the roll of sheet material to the blade member for positioning the blade parallel to the axis of the roll. The positioning means includes a portion thereof distal with respect to the blade in rolling engagement with a surface of the roll to align the roll axis and the cutting edge. In one embodiment, an arm extends from each end of the blade to the roll and a pin protrudes from the arm inside the roll to bear against the inner surface thereof. A bearing, which may be bushing of a diameter substantially less than an inner diameter of the roll, rotates on the pin so that the blade is pendulously suspended from the inner surface of the roll. Graduations are provide on one or both sides of the blade member, and methods are disclosed for using the blade member as a drafting instrument to measure, and to draw horizontal and vertical lines.

  • Patent number: 4712462
    Abstract: A modelmaker's miter jig has a work support surface and includes, in one aspect, a recessed rule slideable in a channel formed in the work support surface, and a stop member mounted on the rule and protruding above the support surface. A lock secures the rule and stop so as to register a workpiece in a desired relation to a saw guide. In another aspect, the jig includes a base member dependent from the work surface and having a clamp-engaging face for receiving a clamp to removably mount the jig on a table top. A preferred embodiment is formed as an extrusion.
