ABSTRACT:
A flexure assembly is provided for mounting a load-receiving platform to a fixed base, said base having associated therewith a force sensing device for coupling to said platform. The assembly comprises at least one flexure member including a stack of at least two flexible leaves. The stack is rigidly coupled along a first side thereof to said platform, and said stack is rigidly coupled along an opposite side thereof to said base, said stack being inclined from the vertical and being sufficiently rigid to support said platform from said base. The stack is further sufficiently flexible to tend to deflect and traverse a slight arc in response to a loading force being applied to said platform by receiving a load thereon, each of said leaves having a substantially planar shape when in a nondeflected state and lying in substantially parallel planes when in the nondeflected state, whereby said force sensing device can be coupled to said platform along a substantially horizontal axis to thereby render an indication of the magnitude of said load.
