Patent ID: 7260916

Claim:
A device for forming a displaceable wall structure, comprising one or more building elements each provided with a first and a second suspension arrangement for suspension of the building element from a support unit and for substantially horizontal movement of the building element in a forward and backward direction along the support unit, the first and the second suspension arrangements, when cooperating with the support unit, being arranged spaced from each other along an extension of the building element parallel to said substantially horizontal movement direction, and the building element has a pivoting means defining a substantially vertical pivot axis about which said building element is arranged to pivot, said first suspension arrangement being pivotable away from and towards the support unit, during pivoting of the building element about the pivot axis, said device further being provided with a rest member adapted to support said building element during an initial pivot motion of said building element, and the device further comprising a locking mechanism cooperating with the pivoting means to thereby lock the pivoting means in a predetermined position against horizontal movement during pivoting of the building element about the pivot axis, wherein the device comprises a locking member having a first component arranged on the building element between the first suspension arrangement and the pivot axis of the pivoting means, and a second component comprising a surface by which the first component is arranged to be guided and to cooperate to thereby lock the pivoting means in said predetermined position against horizontal movement in a direction from said pivoting means towards said first suspension arrangement during at least a first part of the pivot motion of the building element, and the cooperation between said first component and said second component constitutes the locking of the pivoting means during at least a first part of the pivot motion of the building element.
