Abstract

A rotatable disk mounted to a baseplate at each corner of a refuse compactor pivots between a first orientation having a horizontal axis of rotation for operation as a wheel and a second orientation having a vertical axis of rotation for operation as a leg. The disk is mounted on a bearing support that interfits with elongated slots formed in the baseplate to enable the height of any corner of the compactor, independent of the orientation of the disk, to be adjusted. In one embodiment, the bearing support comprises a nylon block into which an axle of the rotatable disk is snap-fit. In another embodiment, the bearing support comprises an angle bracket to which the axle is welded.

  1. 1. For supporting an appliance cabinet on a horizontal surface by attachment to a baseplate extending from a lower portion of the cabinet, a combination levelling wheel and leg assembly, comprising:a baseplate attachable to a lower portion of said cabinet and having a planar extendable therefrom;a rotatable member mounted to a predetermined location on said planar portion of said baseplate;means for pivoting said rotatable member on said planar portion of said baseplate between a first orientation having a horizontal axis of rotation for operation as a wheel, wherein the wheel intersects the plane of the planar portion, and a second orientation having a vertical axis of rotation for operation as a leg;means for securing the rotatable member to said planar portion of said baseplate selectively in said first and second orientations; andmeans for adjusting said predetermined location on said planar portion of said baseplate for levelling the cabinet.
  2. 24. For supporting and levelling a refuse compactor on a horizontal surface, a combination wheel and leg assembly, comprising;a baseplate attachable to each corner of a lower surface of said compactor, said baseplate having first and second parallel slots formed therein;a rotatable member assembly pivotally mounted to each said baseplate, said rotatable member assembly including a rotable member and a bearing support for said rotatable member, one portion of said bearing supportin having a tab for extending into either one of said first and second slots and another portion for receiving a screw extending through either one of said first and second slots, whereby when said tab and said screw are in different slots within said baseplate, said rotatable member is oriented to have a horizontal axis of rotation to operate as a wheel and when said tab and said screw are in a common slot within said baseplate, said rotatable member is oriented to have a vertical axis of rotation to operate as a leg.
  3. 31.31. For supporting and levelling a refuse compactor on a horizontal surface, a combination comprising;a plurality of baseplates respectively attachable at individual corners of a lower surface of said compactor, said baseplates having first and second parallel slots formed therein;a rotatable member assembly pivotally mounted to each said baseplate, said rotatable member assembly including a rotatable member and a bearing support for said rotatable member, one portion of said bearing support having a tab for extending into either one of said first and second slots and another portion for receiving a screw extending through either one of said first and second slots, whereby when said tab and said screw are in different slots within said baseplae said rotatable member is oriented to have a horizontal axis of rotation to operate as a wheel and when said tab and said screw are in a common slot within said baseplate said rotatable member is oriented to have a vertical axis or rotation to operate as a leg.
