Abstract

A retractable safety barricade employed to block off an aisle or entryway, comprising a barricade housing that is mounted to a first support and a safety net attached at one end to a winding tube under spring tension located within the barricade housing and at the other to a pull bar, which may be secured to a second support. When the safety barricade is in its first position, the net is fully retracted onto the winding tube within the barricade housing by means of a coil spring. When the safety barricade is in its second position, the net is extended from housing to span the area between first and second supports, substantially covering the opening between the supports and blocking passage through the area. Operation of the device is performed by a single user, who manually extends or retracts the net barrier using the pull bar.
