  • Patent number: 7931067
    Abstract: Methods and apparatuses are disclosed for laterally restraining a movable partition. In one embodiment, a movable partition includes two laterally spaced structures wherein each structure includes a plurality of hingedly coupled panels. A lateral restraint mechanism is located and configured to prevent lateral displacement of one or both of the two laterally spaced structures. In one embodiment, at least one bracket is substantially rigidly coupled to a hinge of the first structure and a laterally adjacent hinge of the second structure. The at least one bracket may include multiple brackets. Some described methods include a laterally restraining lower edge of a movable partition as well as the installation of lateral restraint brackets including the plumbing, spacing and squaring of the structures in conjunction with such installation.
