Squeegee mounting assembly for a floor scrubber
First Claim
1. A machine for removing a solution from a surface comprising, in combination:
- a chassis moveably supported on the surface, with the chassis including a plate;
a solution pickup assembly for collecting solution from the surface; and
first, second, and third linkage arms each having first and second ends, with the first ends of the first and second linkage arms being pivotably mounted to the plate at first and second spaced, axially aligned locations and with the second ends of the first and second linkage arms being pivotably mounted to the solution pickup assembly at third and fourth spaced, axially aligned locations, with the first end of the third linkage arm being pivotably mounted to the plate at a fifth location spaced from and parallel to the first and second locations and the second end of the third linkage arm being pivotably mounted to the solution pickup assembly at a sixth location spaced from and parallel to the third and fourth locations, with the third linkage arm having a length between the first and second ends which is adjustable, with the solution pickup assembly being maintained at a generally constant angle relative to the plate independent of the pivotable movement of the linkage arms, with the generally constant angle being variable by adjusting the length of the third linkage arm.

Abstract
A squeegee assembly is allowed to float on the floor surface by first, second and third linkage arms having first ends pivotably mounted to the chassis and second ends pivotably mounted to a mount for the squeegee assembly and allowing movement in more than one plane. The squeegee assembly is maintained at a generally constant angle independent of the pivotable movement of the linkage arms, with the generally constant angle being variable by adjusting the length of the third linkage arm. First and second extension springs have first ends attached to the chassis and have second ends attached to the mount at differing spacing than the first ends to cause the squeegee assembly to center the squeegee assembly relative to the chassis. In the preferred form, the ends of the extension springs attached to the chassis are vertically below the ends of the extension springs attached to the mount of the squeegee assembly to bias the squeegee assembly towards the floor surface. A T-shaped bracket is provided having a head for abutting with the first and second linkage arms to limit the upward extent of pivotable movement of the squeegee assembly and having a leg centered between and for abutting with the first and second linkage arms to limit the horizontal extent of pivotable movement of the squeegee assembly.

13. A machine for removing a solution from a surface comprising, in combination:
- a chassis moveably supported on the surface, with the chassis including a plate;
a solution pickup assembly for collecting solution from the surface;
at least a first linkage arm each having a first end pivotably mounted to the plate and a second end pivotably mounted to the solution pickup assembly, with the first and second ends of the linkage arm being pivotably mounted in a manner allowing relative movement in more than one plane; and
