  • Patent number: 8596593
    Abstract: A worksurface leg mount is provided for interconnecting a support leg to a worksurface. The worksurface leg mount system includes an anchor plate attached to a lower surface of the worksurface, and a mounting plate attached to and optionally recessed in an upper end of the support leg. A fastener extends between and connects the anchor and mounting plates, which are spaced from each other. Loads that enter the mounting plate in discrete directions are transmitted through the fastener and into the anchor plate, where the loads are spread across the interfaces between the anchor plate and worksurface.

  • Publication number: 20060103206
    Abstract: A seating unit comprising a base configured to be positioned on a floor, a torsional energy unit connected to the base, a back connected to the torsional energy unit and a seat rotatably connected to the torsional energy unit. The torsional energy unit biases the back to a forward position. The torsional energy unit further limits angular rotation of the seat between a substantially horizontal seating position and a substantially vertical seating position.
