ABSTRACT:
A panel movement system including top and bottom rails having racks with registration teeth along their lengths; top and bottom rail attachments movably attached to respective ones of the rails for lateral movement along lengths of the rails; and a gear movement synchronization system. Each rail attachment includes a rotatable gear engaging the registration teeth on respective ones of the rails. The gear movement synchronization system connects the rotatable gear of the top rail attachment to the rotatable gear of the bottom rail attachment such that the top and bottom rail attachments move along the rails in unison. The top and bottom rail attachments are adapted to have a panel connected therebetween.
