  • Patent number: 11668599
    Abstract: A shelf bracket assembly is mounted on a vertically disposed shelf upright, and has: at least one weighing device; an anchoring device; and a cantilever for supporting a shelf panel. In a condition where the shelf bracket assembly is mounted on the shelf upright, the cantilever projects from the shelf upright in a substantially horizontal direction. The cantilever has a vertically disposed metal plate. In a Cartesian coordinate system, an extent of the cantilever in a horizontal plane defines a Y-direction, a vertical direction defines a Z-direction, and a direction perpendicular to the Y-direction and the Z-direction defines an X-direction. The at least one weighing device includes: a force-introduction section; a linkage section; and a force-supporting section. The linkage section comprises two weighing plates extending horizontally and parallel to each other. The force-supporting section and the force-introduction section are at least partially formed of vertically extending metal plates.

  • Patent number: 11609132
    Abstract: A load cell has a monolithic measuring body. The monolithic measuring body has: a force-supporting section; a force-introduction section; and a linkage section disposed between the force-supporting section and the force-introduction section. The monolithic measuring body has a longitudinal axis between a force-supporting-side axial end and a force-introduction-side axial end. The longitudinal axis is configured to extend in a horizontal direction. The monolithic measuring body further has, in the force-supporting section, at least one mounting hole for attachment of the monolithic measuring body, the axis of the at least one mounting hole extending in the horizontal direction. At least one strain gauge is configured to sense tensile or compressive deformation of the monolithic measuring body and is in a region of the linkage section on a top side or a bottom side of the monolithic measuring body, the at least one strain gauge being oriented in the horizontal direction.

  • Patent number: 11607059
    Abstract: A shelf bracket assembly mounted upright on a vertically disposed shelf has: a load cell; an anchor; and a cantilever supporting a shelf panel. The cantilever projects from the shelf upright in a substantially horizontal direction. The cantilever has a vertically disposed frame or a vertically disposed metal plate and a mount for the load cell. The load cell has a monolithic measuring body that has: a force-supporting section; a force-introduction section; and a linkage section between the force-supporting section and the force-introduction section. The force-supporting section of the monolithic measuring body is laterally attached to the mount. The monolithic measuring body has at least one mounting hole through which the monolithic measuring body is attached to the mount with a screw extending horizontally through the monolithic measuring body.
