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.
