Abstract
A washing machine having improved resistance toward frictional walking. The washer comprises a cabinet, a tub assembly disposed in the cabinet for processing a wash load and a suspension including a truss-like pedestal for supporting the tub assembly and for permitting the tub assembly to pivot. The supporting feet of the washer are rotatably coupled to the suspension. Preferably, the number of members comprising the suspension is greater than or equal to three times the number of joints comprising the suspension minus eight. With this arrangement, a statically determinant suspension is provided. The substantially continuous contact between the supporting feet and the floor (i.e. the feet automatically conform to the floor surface) increases the frictional resistance, thereby decreasing the probability of frictional walking.
