6397429, Jun 4, 2002
Filed:
Jun 30, 2000
Appl. No.:
09/607247
Inventors:
Donald J. Legatt - St. Michael MN
Paul T. Mueller - Bloomington MN
Wolfgang C. Lehmann - Maple Grove MN
Galen Swenson - Maple Grove MN
Patrick Enzler - Minneapolis MN
Assignee:
Nilfisk-Advance, Inc. - Plymouth MN
International Classification:
A47L 1138
US Classification:
15401, 15320, 15339, 153401
Abstract:
A riding floor scrubber ( ) is disclosed having a relatively narrow cleaning width for passing through relatively narrow passages such as conventional doorways. The riding floor scrubber ( ) includes a recovery tank ( ) that is vertically and laterally arranged and removably attached to the back of a clean solution tank ( ). The clean solution tank ( ) includes spaced parallel side portions ( ) and the recovery tank ( ) extends between the rear ends of the side portions ( ). The recovery tank ( ) is secured by first and second brackets ( ) that extend into recesses ( ) on the clean solution tank ( ), with the bottom of the recovery tank ( ) including a lip portion ( ) resting on a metal plate ( ) of a chassis ( ), with a battery pack ( ) being supported on the plate ( ) between the side portions ( ) of the clean solution tank ( ). The clean solution tank ( ) includes a middle portion ( ) and a lower portion ( ) integrally extending forwardly of the middle portion ( ), with the left side portion ( ) extending to the same longitudinal extent as the lower portion ( ). The clean solution tank ( ) is molded into a complex shape to maximize capacity, with the bottom of the clean solution tank ( ) being recessed to receive the chassis ( ) of a tricycle type to define triangular-shaped volumes ( ).

Squeegee Mounting Assembly For A Floor Scrubber

US Patent:
6519808, Feb 18, 2003
Filed:
Sep 28, 2001
Appl. No.:
09/967132
Inventors:
Donald J. Legatt - St. Michael MN
Paul T. Mueller - Bloomington MN
Wolfgang C. Lehmann - Maple Grove MN
Galen Swenson - Maple Grove MN
Patrick Enzler - Minneapolis MN
Assignee:
Nilfisk-Advance, Inc. - Plymouth MN
International Classification:
A47L 1130
US Classification:
15401, 153401
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.
