Abstract
A sliding door mechanism for closing an aperture in a wall comprises an elongate support, a hanger pivotally connected to the support and arranged to be fixed to the door, and an arm on the support extending in the length direction thereof and carrying spaced apart first rollers. A track which, in use, is fixed to the wall, receives the first rollers. A guide rail mounted on the track. Second rollers are mounted on the support for engaging the guide rail. The arrangement is such that, in use, as the door reaches a closed position in which it closes the aperture from an open position in which the aperture is not obstructed by the door, the guide rail and second rollers causes the support to pivot about the contact points of the first rollers with the track and the hanger pivots relative to the support.

A sliding door mechanism for closing an aperture in a wall comprising:
- an elongate support means;
- hanger means pivotally connected to the elongate support means and arranged to be fixed to the door whereby the door is suspended from the elongate support means;
- an arm on the elongate support means extending in the length direction thereof and carrying a plurality of spaced apart first rollers;
- a track which, in use, is fixed to the wall and receives the first rollers, said rollers providing a downward force component against said track;
- a guide rail mounted on the track, said guide rail having a discontinuous section proximate said aperture;
- and at least one second roller mounted on the elongate support means for engaging the guide rail, said at least one second roller providing an upward force component against said guide rail, the arrangement being such that, in use, the elongate support means is locked to said track by said upward and downward force component and, as the door reaches a closed position in which it closes the aperture from an open position in which the aperture is not obstructed by the door, the guide rail discontinuous section and the at least one second roller causes the elongate support means to pivot about the contact points of the first rollers with the track and the hanger means pivot relative to the elongate support means.
