ABSTRACT:
Disclosed is a portable wall-partition that includes a plurality of panels and at least one hinge that connects each of the plurality of panels to a neighboring panel. A foot is positioned on a lower edge of each of the plurality of panels. The foot includes a first extension and a second extension. Each of the extensions includes a distal end thereof. The first and the second extensions are connected to each other at a proximal end (opposite the end having a wheel) to form a vertex. The foot also includes a spring located at or near the vertex. The spring biases the first and the second extensions toward each other.
