Squeegee assembly
First Claim
1. A squeegee assembly comprising, in combination:
- a flexible wiper blade;
a first retaining element;
a second retaining element, with the flexible wiper blade sandwiched between the first and second retaining elements; and
at least a first retainer, with the retainer including a shaft extending from the first retaining element and having an axis, with the retainer further including a head connected to the shaft and axially spaced from the first retaining element, with the shaft having cross sections perpendicular to the axis of the shaft, with the head having cross sections perpendicular to the axis of the shaft different than the cross sections of the shaft and having different radial extents than the cross sections of the shaft, with the flexible wiper blade including a mounting aperture having cross sections corresponding to and for slideable passage of the cross sections of the head, with the second retaining element having an upper edge, a lower edge and a center section, with the upper and lower edges being formed on a bent section having linear configuration, bent at an obtuse angle relative to the center section, the upper and lower edges abutting with the flexible wiper blade sandwiched between the first and second retaining elements and defining an abutment plane, with the center section having a linear configuration and being spaced from the abutment plane and from the flexible wiper blade, and the second retaining element including a mounting aperture formed in the center section and having cross sections corresponding to and for slideable passage of the cross sections of the head, with the mounting apertures of the flexible wiper blade and the second retaining element being aligned when the flexible wiper blade is sandwiched between the first and second retaining elements, with the shaft extending through the aligned mounting apertures, with the head being positionable relative to the second retaining element between a first position and a second position, with the head in the first position being aligned with the aligned mounting apertures allowing passage of the head through the aligned mounting apertures, with the head in the second position being misaligned with the aligned mounting apertures and abutting with the second retaining element around the mounting aperture of the second retaining element.

Abstract
A squeegee assembly (10, 10′) includes a flexible wiper blade (30) sandwiched between a mounting bracket (32, 32′) and a retaining strap (34, 34′). A retainer (94) has a head (98) which is positionable between aligned and misaligned positions with mounting apertures (82, 92) to allow disassembly, assembly and retention of the squeegee assembly (10, 10′). Arcuate portions (36, 36′, 66, 66′) formed in the mounting bracket (32, 32′) and the retaining straps (34, 34′) have different radiuses. Linear portions (68, 68′, 70, 70′) of the retaining straps (34, 34′) have upper and lower edges (72, 74) bent from center portions thereof. The mounting brackets (32, 32′) include L-shaped slots (46) for slideably receiving vertical bolts (56) of the floor maintenance machine (12).
