Abstract:
1. A leveling foot for a household appliance, comprising: a castor configured to contact and roll on a surface; a substantially tubular internal ring comprising external threads provided thereon and a rebound configured to interrupt the external threads at a lower end of the external threads, the castor being positioned inside the internal ring; and an external ring positioned around and coupled to the internal ring, the external ring comprising internal threads configured to mate with the external threads of the internal ring, the rebound of the internal ring being configured to inhibit and create an obstacle to removal of the external ring from the lower end of the external threads of the internal ring, the external ring being configured to move on the internal ring when rotated about the internal ring such that rotation of the external ring after the external ring contacts the surface lifts the castor from the surface, fastens and adjusts a height of the household appliance, and compensates for irregularities in the surface.
