Abstract
Abstract A cabinet or support structure is equipped with a pair of large wheels mounted on wheel hubs that are eccentrically supported upon an axle, the axle being rotatable to raise the wheel hubs and thereby the wheels so that the bottom of the cabinet can seat on the floor or floor carpet, and when the axle is rotated to lower the hubs, the cabinet can then be moved on the large wheels together with edge-supported casters. Means are provided for rotating the axle and locking it in adjusted positions.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
148 words
In a cabinet structure adapted for stationary and mobile use on a floor, a cabinet frame having sides and a base adapted to a rest on the floor, a tubular axle housing secured to said frame and defining a continuous slot including first and second elongated axial sections and a circumferential section communicating one end of each of said elongated axial sections, an axle rotatably mounted in said housing and defining an elongated axial slot, wheel hubs eccentrically mounted on said axle for rotation therewith whereby rotation of said axle selectively raises and lowers said wheel hubs, wheels rotatably mounted on said hubs, and a crank telescopically received in said axle and including a radial pin extending through the axial slot of said axle and said slot of said axle housing for selectively rotating said axle to bring said wheels to positions above and below said cabinet base.
Claim 2
Dependent Claim
148 words
In a cabinet structure adapted for stationary and mobile use on a floor, a cabinet frame having sides and a base adapted to a rest on the floor, a tubular axle housing secured to said frame and defining a continuous slot including first and second elongated axial sections and a circumferential section communicating one end of each of said elongated axial sections, an axle rotatably mounted in said housing and defining an elongated axial slot, wheel hubs eccentrically mounted on said axle for rotation therewith whereby rotation of said axle selectively raises and lowers said wheel hubs, wheels rotatably mounted on said hubs, and a crank telescopically received in said axle and including a radial pin extending through the axial slot of said axle and said slot of said axle housing for selectively rotating said axle to bring said wheels to positions above and below said cabinet base.
Claim 3
Dependent Claim
39 words
The structure of claim 1 wherein said axle is a tube having a square cross section and said telescopically received crank also has a square cross section thereby to prevent relative rotational movement between said crank and said axle.
Claim 4
Dependent Claim
80 words
The structure of claim 2 wherein said first elongated axial section of said slot in said axle Housing is longer than said second elongated section therein whereby when said pin of said crank is traveling in said first axial section, said crank may be inserted further into said axle and said axle housing and when said pin is traveling in said second axial section of said slot, the insertion of said crank is limited for easier access to said crank.
Claim 5
Dependent Claim
49 words
The structure of claim 3 wherein said crank is jointed at an intermediate position to include an arm which may be rotated between a storage position wherein the arm is coaxial with said axle and an operative position wherein said arm extends perpendicularly to said axle for rotation thereof.
