Claims20
A carpet extractor comprising:
- an open top recovery tank for collecting and storing spent cleaning fluid and dirt removed from a surface to be cleaned, the recovery tank including an upper rim around the open top and a pair of opposed, outwardly projecting cam followers on exterior sides of the recovery tank adjacent the upper rim;
- a lid having a lower rim that mates with the recovery tank upper rim to close the open top of the recovery tank and a pair of journals;
- and
- a handle rotatably mounted to the lid between a closed position and an open position, the handle having at its outer ends two opposed cam mounting sockets that each have a cam surface and a socket on an interior face thereof, and the handle is rotatably mounted to the lid by the sockets and the journals;
- wherein the cam surfaces are configured to interface with the cam followers to releasably lock the lid to the recovery tank when the handle is in the closed position and to release the lid from the recovery tank and to raise the lid from the recovery tank when the handle is in the open position.

A carpet extractor comprising:
- a recovery tank for collecting and storing the spent cleaning fluid and dirt removed from a surface to be cleaned, the recovery tank including an open top, an upper rim around the open top, and a pair of cam followers adjacent the upper rim, the cam followers projecting outwardly from exterior sides of the recovery tank in opposite directions;
- a lid comprising a pair of journals and a lower rim that mates with the upper rim of the recovery tank to close the open top of the recovery tank;
- and
- a handle rotatably mounted to the lid via the pair of journals and rotatable between a closed position and an open position, the handle comprising a pair of cam surfaces;
- wherein the cam surfaces are configured to interface with the cam followers to releasably lock the lid to the recovery tank when the handle is in the closed position and to raise the lid slightly from the recovery tank and release the lid from the recovery tank when the handle is in the open position.

A carpet extractor comprising:
- a recovery tank for collecting and storing spent cleaning fluid and dirt removed from a surface to be cleaned, the recovery tank including an open top, an upper rim around the open top, and a plurality of cam followers adjacent the upper rim, the cam followers projecting outwardly from exterior sides of the recovery tank in opposite directions;
- a lid comprising a plurality of journals and a lower rim that mates with the upper rim of the recovery tank to close the open top of the recovery tank;
- and
- a handle rotatably mounted to the lid via the plurality of journals and rotatable between a closed position and an open position, the handle comprising a plurality of cam surfaces, wherein the cam followers ride along the cam surfaces during rotation of the handle between the closed position and the open position;
- wherein the cam surfaces are configured to interface with the cam followers to releasably lock the lid to the recovery tank when the handle is in the closed position and to raise the lid from the recovery tank and release the lid from the recovery tank when the handle is in the open position;
- and
- wherein the cam surfaces are configured to urge the raising of the lid from the recovery tank as the cam followers ride along the cam surfaces during a rotation of the handle to the open position.
