ABSTRACT:
A load sensing assembly adapted to measure the weight of loads which act with both vertical and horizontal direction force components by resolving such force components solely into a vertical downward force component representative of the weight of the load is disclosed. This assembly comprises a first support member having a generally inclined leg portion fixedly mounted against movement, a second support member moveably mounted with respect to the first support member having a load support portion for supporting the load to be measured, a third member for interconnecting the first and second support members toward first ends thereof formed of elastically deformable material capable of transmitting only tensile force and no other types of force and a fourth member interconnecting the first and second support members toward the opposite ends thereof also formed of elastically deformable material capable of transmitting only tensile force and no other types of force. Together these four members form a quadrilateral load support structure for supporting a load to be measured which flexes under the load for transmitting only vertically downward forces applied by the load and no other forces. A load cell measures the load via the quadrilateral structure and produces a signal representative of the magnitude of the vertical downward force of the load.
