  • Publication number: 20220211171
    Abstract: A pedestal leg assembly includes a pedestal leg and floor base. The leg includes a plurality of teeth near the bottom end of the leg and a connecting bolt in a threaded engagement with the bottom end of the leg. The floor base includes a recessed portion having a slot in its bottom surface to receive the bolt and a release mechanism configured to pivot between a lock position and a release position. In lock position the release mechanism engages at least one of the teeth to prevent rotation of the pedestal leg in at least one direction. When pivoted into release position, the release mechanism is moved away from engagement with the teeth to allow rotation of the pedestal leg in both clockwise and counterclockwise directions. The pedestal leg assembly may include a powered connection to receive input power and/or a communication signal at the floor base and transfer the power and communication signals to a supported table top surface.
