ABSTRACT:
My invention provides a movable overrider system for moving a reference element board 15r over the front faces of track-supported module boards 15 of a modular scheduling board system 10. An upper wall track 12 supports a trolley bracket 20 that carries a pair of wheels 21 engaging a retainer lip 17 and resting on a path 14 of the upper wall track 12, while lower track 11 supports boards 15. Holders 25 on the lower edge 24 of trolley bracket 20 hold the back of the reference element board 15r to hang downward from the trolley bracket. Holders 25 and bracket 20 are dimensioned to suspend reference board 15r at the same vertical level as track-supported boards 15 so that reference board 15r can roll along the length of tracks 11 and 12 and override the track-supported boards while staying in horizontal alignment.
