Barrier
First Claim

1. An impact barrier comprising:
- a first support;
a second support;
a first arm moveable about the first support to rotate about a substantially horizontal pivot axis;
a second arm moveable about the second support to rotate about a substantially horizontal pivot axis;
a coupling mounted to the first arm and arranged to slide relative to and along the first arm and the second arm, wherein;
the first and second supports are spaced across an opening, and the impact barrier is arranged between an open position and a closed position, such that in the closed position, the first and second arms are arranged in combination to traverse the opening; and
when in the closed position, the coupling is arranged to slide along and relative to the first and second arms, by a distance of at least 25% of a length of one of the first arm and the second arm, from a first position in which the coupling is mounted on only the first arm to a second position in which the coupling is mounted on both the first and second arms; and
a projection provided on the second arm, the projection arranged to abut the coupling to impede movement of the coupling along the second arm beyond the second position when the impact barrier is arranged in the closed position.

Abstract
There is provided a barrier and a method of opening and closing a barrier. The barrier including a first arm moveable about a first support, a second arm moveable about a second support and at least one coupling. The first and second supports are spaced across an opening and the barrier is arranged between an open and closed position, such that in the closed position, the arms are arranged in combination to traverse the opening. The barrier is further arranged in a locked position, such that the coupling is slidably coupled to the first and second arms. The barrier improves the safety of loading bay areas in order to allow the efficient transfer of goods on freight transportation vehicles.

9. A method of opening and closing an impact barrier comprising the steps of:
-
moving a first arm about a first support to rotate about a substantially horizontal pivot axis; moving a second arm about a second support to rotate about a substantially horizontal pivot axis, wherein the first and second supports are spaced across an opening, and the impact barrier is arranged between an open position and a closed position, such that in the closed position, the first and second arms are arranged in combination to traverse the opening; arranging the impact barrier into the closed position by arranging the first and second arms in combination to traverse the opening; sliding a coupling, by a distance of at least 25% of a length of one of the first arm and the second arm, from a first position in which the coupling is mounted on only the first arm to a second position in which the coupling is mounted on both the first arm and the second arm; and impeding movement of the coupling along the second arm beyond the second position by a projection provided on the second arm that abuts the coupling when the impact barrier is arranged in the closed position. - View Dependent Claims (10, 11, 12, 13)
