ABSTRACT:
A support assembly for a washing machine includes a cabinet structure for enclosing the various working parts of the machine and a mount secured to the assembly of working parts of the machine for movement therewith. The cabinet base has an upwardly facing generally spherical bearing surface and the mount includes a generally spherical lower support surface. An intermediate member is positioned between the bearing surface and support surface and is formed with opposed spherical faces complimentary to the bearing surface and to the support surface respectively. A first relatively low coefficient of friction interface is provided between the intermediate member and one of the bearing and support surfaces and a relatively high coefficient of friction interface is provided between the intermediate member and the other of the bearing and support surfaces so that relative motion between intermediate member and either of the base and the mount respectively in response to movement of the mount tends to occur at the low coefficient of friction interface. The intermediate member has an interfering engagement with the one of the base and the mount with which it has the low coefficient of friction interface upon predetermined movement of the mount so that relative movement between intermediate member and either of the base or the mount in response to greater than the predetermined movement of the mount occurs at the high coefficient of friction interface.
