A gate apparatus comprising a first frame, a second frame and a plurality of rails, wherein each of the first and second frames comprises a vertical post and a plurality of cross-bars, and wherein the cross-bars of the first frame increase in length from the top cross-bar to the bottom cross-bar, and the difference in length between each cross-bar and the one below it is at least equal to the width of each rail, and wherein the cross-bars of the second frame increase in length from the bottom cross-bar to the top cross-bar, and the difference in length between each cross-bar and the one above it is at least equal to the width of each rail. The gate apparatus includes a means of attaching the rails to the cross-bars that allows the rails to pivot vertically. A wheel is attached to the vertical post of the second frame.
A gate apparatus comprising a first frame, a second frame and a plurality of rails, wherein each of the first and second frames comprises a vertical post and a plurality of cross-bars, wherein the plurality of cross-bars on each of the first and second frames comprises a top cross-bar and a bottom cross-bar, wherein each rail comprises a first end and a second end, wherein the first end of each rail is pivotally connected to a cross-bar of the first frame and the second end of each rail is pivotally connected to a cross-bar of the second frame, wherein the cross-bars of the first frame increase in length from the top cross-bar to the bottom cross-bar, and the difference in length between each cross-bar and the one below it is at least equal to the width of each rail, wherein the cross-bars of the second frame increase in length from the bottom cross-bar to the top cross-bar, and the difference in length between each cross-bar and the one above it is at least equal to the width of each rail, wherein the cross-bar that is second from the top is extended by a length that is at least equal to the combined width of all of the rails beneath the one that fits into this second cross-bar.
A gate apparatus comprising a first frame, a second frame, a plurality of rails, and a center support attached to the rails, wherein each of the first and second frames comprises a vertical post and a plurality of cross-bars, wherein the plurality of cross-bars on each of the first and second frames comprises a top cross-bar and a bottom cross-bar, wherein the cross-bars of the first frame increase in length from the top cross-bar to the bottom cross-bar, and the difference in length between each cross-bar and the one below it is at least equal to the width of each rail, wherein the cross-bars of the second frame increase in length from the bottom cross-bar to the top cross-bar, and the difference in length between each cross-bar and the one above it is at least equal to the width of each rail, wherein the center support comprises two sets of cross-bars, one on either side of the center support, wherein each rail comprises a first end and a second end, wherein the first end of each rail is pivotally attached to a cross-bar of either the first or second frame, and wherein the second end of each rail is pivotally attached to a cross-bar of the center support such that the rails pivot vertically on either side of the center support and such that the gate apparatus folds in the center when swung vertically upward or downward.
