The invention relates to a universal safety barrier for a railing or access platform. The barrier comprises a base plate 1, means 10, 11 for attaching the base plate to a surface, a pivot support 3 extending from the base plate 1 with a horizontal pivot pin 4 through the pivot support 3 and an elongate bar 5 extending from the pivot support 3. The pivot pin 4 extends through the bar 5 such that a minor part of the bar 5 extends to one side of the pin 4 and a major part of the bar extends to the other side of the pin 4. A stop means 6 on or in the pivot support 3 engages the minor part of the bar 5 to hold the bar 5 in a horizontal position across an opening. The pivoting arrangement is such that the bar 5 can be raised to allow passage through an opening, but falls under its own weight when released, to close the opening. The stop means 6 is preferably a screw 6 that forms an adjustable stop. The base plate 1 is designed to be bolted to a surface. |
