发明名称 Portable line barrier
摘要 A portable line barrier including a plurality of telescopically extendable poles. Further provided are a pair of line payer heads. Each line payer head is coupled to a separate pole and each head has a container with a hollow interior and a closeable opening for allowing access to the interior. A spool is disposed within the interior of the container and is rotatably coupled to the container. A plurality of loops with each loop are coupled to a separate pole which is not coupled to a line payer head. Each loop is adapted for holding a cable within. A cable which has one end coupled to and wrapped around the spool of one of the line payer heads is included. Another end extends through the loops of the poles and is coupled to and wrapped around the spool of the other line payer head such that the poles, line payer head, and loops create an extendable barrier. Therefore, when the cable is extended between the line payer heads and the poles are positioned on a surface in a spaced relationship, the barrier is placed in an operable configuration.
