Load cell force transmitting assembly for vehicle weighing scales and the like

Abstract

Abstract AN ASSEMBLY FOR SUPPORTING A LOAD RECEIVING STRUCTURE AND TRANSMITTING THE WEIGHT OF A LOAD APPLIED THERETO TO A LOAD CELL. THE ASSEMBLY HAS AN IMPACT-ABSORBING RESILIENT PAD ON WHICH A LAYER OF ANTIFICTION MATERIAL IS DISPOSED TO PROVIDE A SURFACE WHICH SLIDABLY SUPPORTS THE LOAD-RECEIVNG STRUCTURE FOR HORIZONTAL MOVEMENT. THE PAD IS FIXED ON THE CENTRAL PORTION OF A FLEXURE PLATE OR DIAPHRAGM HAVING ONLY ITS OPPOSITE END REGIONS SO ANCHORED TO A STATIONARY SURFACE THAT THE INTERMEDIATE PORTIONS OF THE PLATE BETWEEN EACH END REGION AND THE CENTRAL REGION ARE FLEXED BY THE LOAD TRANSMITTED TO THE PAD. THE CENTRAL PLATE PORTION IS THUS VERTICALLY DISPLACEABLE TO ENGAGE AND TRANSMIT LOADS TO THE LOAD CELL STRESS COLUMN LOCATED VERTICALLY BELOW THE CENTRAL PORTION. THIS FLEXURE OF THE PLATE AND THE HORIZONTAL PLATFORM MOVEMENT PROVIDES FOR THE TRANSMISSION OF ONLY THOSE FORCES WHICH SUBSTANTIALLY AXIALLY ALIGN WITH THE LOAD CELL COLUMN. COVER PLATES ON OPPOSITE SIDES OF THE FORCE TRANSMITTING ASSEMBLY COOPERATES WITH THE FLEXURE PLATE AND STANDS ON WHICH THE FLEXTURE PLATE END REGIONS ARE ANCHORED TO PROVIDE AN ENCLOSURE FOR THE LOAD CELL.
