Abstract
A weighing scale comprising a housing having an upper platform for receiving a load, and a base; a lever assembly comprising a plurality of levers, each of which is in operative contact with the upper platform and supported by a post element mounted on the base. A cantilever beam is mounted on the base and positioned between the lever assembly and the base. A weight-transmitting pin is provided for supporting the lever assembly and acting on the cantilever beam for transmitting the load from the intermediate cover to the cantilever beam through the lever assembly. A strain gauge element is fixed on the cantilever beam for converting a strain developed therein into an electrical signal. An indicator responsive to the electrical signal is provided such that a displacement of the upper platform into the housing results in a corresponding movement of the levers, and exerts a force on the cantilever beam through the weight-transmitting pin to cause the strain gauge element to develop the electrical signal and causes the indicator to display a weight of the load. The arrangement of the lever assembly and weight-transmitting pin prevents variation caused by differing load positions on the upper platform.
