Abstract: A device for forming a displaceable wall structure, comprising one or more building elements each provided with a first and a second arrangement for suspension of the building element from a support unit and for substantially horizontal movement of the building element forward and backward along the support unit. The first and the second suspension arrangements, when cooperating with the support unit, are arranged spaced from each other along the extension of the building element parallel to said substantially horizontal movement direction, and the building element includes another element for pivoting the building element about a substantially vertical pivot axis.
