Low profile side squeegee assembly
First Claim
Patent Images
1. A device for maintaining a ground surface, comprising:
- a housing with a peripheral edge;
a squeegee assembly;
a plurality of torsion elements connected between said peripheral edge and said assembly, and configured to apply a downward biased force to maintain the squeegee assembly in contact with the ground.

Abstract
A low-profile side squeegee assembly for surface maintenance vehicles, capable of cleaning under so-called “toe kicks”. In contrast with typical suspensions that are mounted directly above the center of the squeegee assembly, and are therefore too tall to fit under toe kicks, a low-profile suspension attaches at the ends of a squeegee assembly, and uses torsion springs to provide a downward force on the squeegee assembly. In order to counteract any potential twisting effects that might result from suspending the squeegee from the ends rather than the center, the squeegee assembly is mounted at an angle.

7. A device for maintaining a ground surface, comprising:
-
a housing having a front, rear and side peripheral edges;
at least one squeegee assembly having first and second longitudinal ends; and
a plurality of connecting elements connecting said first and second ends to said housing, said connecting elements providing a bias force between said housing and said assembly to urge said assembly into contact with said surface. - View Dependent Claims (8)

13. A device for maintaining a ground surface capable of accessing ground spaces substantially occluded by objects which are proximate the ground surface, comprising:
-
a first housing a second low profile housing being attached to said first housing and having an upper surface defining an at least partially enclosed space and a maximum upper clearance distance between the upper surface and ground surfaces, said upper clearance distance being less than the distance of said object to the ground, said second housing having a peripheral edge and a squeegee assembly at the peripheral edge thereof;
a plurality of torsion elements connected at one end to said second housing and said squeegee assembly, and located in said partially enclosed space, and configured to apply a downward biased force to maintain the squeegee assembly in contact with the ground. - View Dependent Claims (14)
