ABSTRACT:
A bathroom platform scale is disclosed having a reinforced plastic base and platform. The platform is carried by a pair of triangular-shaped actuation levers which directly engage a single transducer, such as a strain gauge, centrally located in the base, to sense the weight on the platform. Such an arrangement allows for a relatively compact scale. The triangular-shaped levers are supported by knife edge bearings which define a fulcrum. An integrally formed tongue extending from an apex from each of the triangular-shaped levers applies the weight distributed on the platform to the transducer. The triangular-shaped actuation levers are also self-aligning, thus facilitating assembly of the scale.
