Scrub deck retraction apparatus

摘要

A scrub deck assembly (59) comprises a scrub deck frame (76) and a pivot arm (70) having a first end (72) and a second end (74). The pivot arm is rotatably coupled to the scrub deck frame at the first end, and a scrub brush (56A) is operably coupled to the pivot arm at the second end. The scrub deck assembly further comprises a retraction mechanism (80) configured to allow movement of the pivot arm, relative to the scrub deck frame, about the first end. A release mechanism (92) is operably coupled to the retraction mechanism, and is configured to disengage the operation of the retraction mechanism.

1. A method operating a scrub deck retraction apparatus comprising:
providing or obtaining a scrub deck assembly including:
a first rotatable brush operably coupled to a scrub deck frame;a second rotatable brush operably coupled to a pivot arm, the pivot arm rotatably coupled to the scrub deck frame at a pivot point; anda scrub deck retraction apparatus including a gas spring extending between the scrub deck frame and the pivot arm and a release mechanism coupled to the gas spring, the release mechanism also rotatably coupled to the pivot arm creating an over-center cam mechanism, the gas spring including a gas containing housing and a gas spring rod;rotating the release mechanism from an engaged position to a released position, thereby extending the gas spring rod from the gas containing housing, wherein rotating the release mechanism comprises rotating an end of the gas spring rod above an over-center line; andretracting the second rotatable brush relative to the first rotatable brush by rotating the pivot arm about the pivot point.
