Title:
QUICK-CHANGE SQUEEGEE FOR FLOOR SCRUBBER
Document Type and Number:
WIPO Patent Application WO2005107561
Kind Code:
A3
Abstract:
A squeegee blade (15) is mounted to a mounting plate (11) carried by the frame of a floor scrubber by means of a structure which permits the blade to be changed quickly and without tools. A retainer member (13) is hinged to the mounting plate (11) for rotation between an open position permitting the blade to be replaced manually, and a closed position in which the retainer secures the blade in place for use. The retainer (13) is then secured to the mounting plate by means of a hand fastener which in the illustrated embodiment is an internally threaded retainer nut received on a threaded stud (32) fixed to the mounting plate (11). The nut is in the form of a knob (17) so that it may be tightened or loosened by hand.
