Abstract
In a strain gage weighing scale with a load platform, a plurality of foot structures support the platform. The invention is an improvement in each foot structure of a sandwich with a bottom support plate, a pair of spaced first cylindrical roller fulcrums on the plate, a floating beam plate on the first fulcrums and spaced above and coextensive with the bottom plate. A pair of differently spaced and equally offset second cylindrical roller fulcrums on the beam plate support the platform. Suitable strain gages are secured to the beam any place between the closer pair of fulcrums. The entire sandwich is held together by a deformable plastic housing that secures the plates and fulcrums together and is barb-connected to the platform. The strain gages are connected to conventional converting structure measuring the change in resistance under load and calibrated to read weight. The deformable plastic housing holding the sandwich is an integral molding with structural details reducing friction between the parts. The overall result is a lower profile scale for common household use.
