  • Patent number: 9585485
    Abstract: A seating device can include a seat and a base connected to the seat to support the seat. A tilt mechanism can be connected to at least one of the base and the seat. The tilt mechanism can include at least one of (a) at least one seat connecting member connecting the seat to an upper portion of the base, (b) a plurality of resilient fingers that are attached to the base to engage a floor and flex in response to a user providing a force while sitting or leaning on the seat, and (c) an elastomeric floor engagement member that is attached to the base and has a bottom peripheral portion that contacts a floor and is flexible in response to a user providing the force. In some embodiments, the tilt mechanism may include all of elements (a)-(c).

  • Patent number: 9565945
    Abstract: A seating device can include a height adjustment mechanism that permits a height of a seat to be adjusted. The height adjustment device can be configured so that a user may provide a force to provide upward height adjustment and may also provide a force to allowing for a controlled downward height adjustment of the seat. The height adjustment device can include an actuator that is connected to a rotatable member via linkages. An end of one of the linkages may engage the rotatable member to prevent rotation of the rotatable member, which can prevent height adjustment of the seat. Movement of the actuator may cause the linkages to move so that the rotatable member is free to rotate so that a user may provide a force on the seat to effect height adjustment of the seat and/or cause the seat to be lowered at a desired speed.

  • Patent number: 8480171
    Abstract: A chair having a seat rotatably attached to a tilt spring portion of a tilt mechanism such that the tilt spring is activated by movement of the seat. A backrest and/or the seat can be rotatably connected to the tilt mechanism by parallel arm arrangements which permit the seat and backrest to tilt relative to each other. A tilt limiter can have a magnetic member which facilitates full movement of the tilt limiter between free and locked positions, and which creates an audible indication of full movement of the tilt limiter. The seat/backrest can be made from a flexible mesh material secured to a rigid overmolding which surrounds and is attached to an inner frame of the seat/backrest wherein an outer surface of the overmolding forms an outer surface of the seat/backrest frame and attachment of the overmolding causes the inner frame to stretch the mesh to a final condition.

  • Patent number: 5906420
    Abstract: An office furniture system of free standing furniture elements which can be linked to each other comprises a modular desk unit and a modular storage unit. The modular storage unit occupies the same floor footprint as a rectangular desk unit. The separate storage unit enhances the storage capacity of an office layout since the mounting of drawers and shelves are not limited by the desk unit configuration. The storage unit has compatible lay-in wiring trays, accepts compatible modular power components and accepts the same privacy partition panels and other accessories as are mounted to the desk units. When the desk unit and the storage unit are linked into an integrated office design, a continuous pathway is provided for the electrical, communication and data wiring required for the office system. Power cables are physically separated from the data and communication wires.

  • Patent number: 5454536
    Abstract: Disclosed is a pedestal base for furniture, such a chair. The pedestal base is comprised of a plurality of radially oriented leg members which converge on a central hub, the hub and all of the leg members being formed as an integral piece of molded plastic. The central hub has an upper portion which is adapted to receive a plastic bushing and a lower molded portion which in combination with the bushing holds a chair seat height adjustment mechanism, such as a pneumatic cylinder. The chair base is lightweight and less expensive to manufacture than prior metal and wood chair bases.

  • Patent number: 5029940
    Abstract: A tilt control mechanism that is mounted to the underside of a chair bottom, and permits the user or sitter to selectively control the chair height, as well as the degree of chair tilt. A tension adjustment mechanism is provided to permit the user to change the amount of spring tension exerted against the chair bottom when the chair is tilted back. Finally, a structural support is provided which interconnects the seat bottom with the tilt mechanism, and transmits downwardly-exerted weight to the mechanism. Each of these four mechanisms comprises a number of parts seated within a die cast enclosure or housing.
