A weighing platform is supported by a plurality of force- transmitting assemblies. Upon sideways movement of the platform, the force-transmitting assemblies and platform interact to align and center the platform. In one embodiment, each force transmitting assembly includes a slider 86 which is movable along a base surface 120. A rocker pin 102 transmits force between the slider and a load cell beam 76 connected with the platform. When the platform is moved the rocker pin is tilted to a maximum offset condition in which horizontally offset vertical force components are applied to the rocker pin. Continued movement results in movement of the slider relative to the base. When movement of the platform is interrupted by engagement with a bumper 64. the horizontally offset vertical force components applied to the rocker pin cause it to tilt to an aligned condition in which only vertically aligned force components are applied to the rocker pin. In another embodiment the slider and a spherical force transmitting member are connected with the base and the platform moves relative to the slider when the force transmitting assembly is in a maximum offset condition. <IMAGE> |
