Abstract
A fixture includes a shelf upon which items may be placed. In one implementation, the shelf is supported by four load cells that provide load cell data that may be used to calculate weight data for the load on the shelf. The load cells are mounted underneath a frame, with an upper portion of a load mount extending upward through the frame and engaged to the shelf. The shelf and the frame include stiffeners to increase rigidity, improving the quality of the load cell data. Electronics and a wiring harness are located underneath the frame. In this configuration, assembly of the fixture may be accomplished completely from the underside, simplifying assembly.
