  • 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.
