Abstract
A gate system () includes two spaced sides () defining a work area () between the sides (). A first opening () is defined between first ends of the sides (), and a second opening () opposite to the first opening () is defined between second ends of the sides (). Two gates () for opening/closing the first and second openings () are respectively coupled with two shafts () rotatably supported by one of the sides (). The shafts () are rotatably interconnected wherein pivoting of one of the gates () in a direction causes pivoting of the other gate () in an opposite direction. Each gate () includes a groove () that receives a vertical beam () of the other side () when the gate () is in a closed position. Biasing elements in the form of gas cylinders () between the side () and the gates () prevent the gates () from slamming into their closed positions.
