ABSTRACT:
An expandable gate is described which includes a top horizontal guide rod, a bottom horizontal guide rod and vertical bar members extending from the top guide rod to the bottom guide rod. Each of the bar members has a top guide rod slot and a bottom guide bar slot and the top guide rod extends through each of the top guide rod slots and the bottom guide rod extends through each of the bottom guide rod slots. The vertical bar members may slide horizontally on guide rod members between an open expanded position where the bars are spaced further apart from one another and a closed collapsed position where the bars are closer together. The bar members each have spring connection holes at spaced locations between said top guide rod slot and said bottom guide rod slot. Elongated flexible tension bar springs are provided which lie flat when no forces are applied to the springs. Each of the bar spring have a central opening and have an elongated upper end opening and an elongated lower end opening. The springs have overlapping ends are positioned between adjacent bar members. First connectors rigidly attach a central portion of each spring to a bar member. Second connectors slidingly attach an upper end portion and a lower end portion of each spring to a bar member and the springs urge the vertical bar members to move closer together to the collapsed closed position.
