Abstract
A barrier that is pressurized after being assembled from multiple pieces. The barrier include a first end frame, a second end frame, and a gate engaged between the end frames. The first and second end frames are engaged at their lower members such that the first end frame and second end frame are not integral and not one-piece with each other, and such that the first and second end frames still provide for a pressurized barrier, that is a barrier that is resiliently mounted between two locations so as to be self-supporting between two locations even if spaced from the floor. In a preferred embodiment of the invention, the first end frame, second end frame, and gate have generally the same length so as to minimize the storage area needed to store the barrier prior to assembly.
