Abstract

A sliding door arrangement comprises a door which is slidably moved and is arranged to enclose an opening, a rail assembly coupled to the door allows the slidable movement of the door for opening and closing the opening and a securing mechanism which pulls the door inward so that the door engages the opening. The rail assembly has a rail system which is positioned at a top end and at a bottom end of the door and the rail system is mounted on a housing, a plurality of guides coupled to the door, the guides engage the rail assembly such that the door is slidable in a substantially horizontal direction. At least one shaft having a vertical axis is rotated about the vertical axis by the securing mechanism, the shaft has first end and a second end such that each end is respectively coupled to the rail assembly, the rail assembly has a rail system which is positioned at a top end and at a bottom end of the door and are mounted on a housing. A cam is mounted to a first end and a second cam is mounted to a second end of at least one vertical shaft and each cam is coupled to one guide of the plurality of guides, the cams are substantially coaxial and are parallel to a vertical axis of the shaft, each cam is mounted respectively to the guides wherein the vertical axis of the cams are off set in respect to the vertical axis of the shaft such that the shaft is arranged to rotate about the vertical axis of the cam, a first rotation of the shaft forces the door into the opening and a second rotation of the shaft forces the door away from the opening while the guides remain on the rail system, the shaft is driven by a rotation device of the securing mechanism, the rotation device pivots about a generally vertical axis such that a drive mechanism which extends outwardly substantially perpendicular to the axis of the rotation device and is coupled to the shaft.
