FOLDABLE SAFETY FENCE WITH A REPLACEABLE SAFETY INDICATOR HAVING EASY CONNECTING STRUCTURE

摘要

A foldable safety warning sign having easily detachable safety display units is provided to set up easily on a construction site and retracted for safekeeping by installing retractable safety display units made of mesh sieves on rotating fixing plates of cross linked links fixed to fixed and moving devices installed on supporting stands. A foldable safety warning sign comprises plural vertical supporting stands(1,1'), fixed devices(2) installed on upper parts of the supporting stands, and slidable moving devices(3,3') installed on middle sections of the supporting stands. One ends of cross linked links(5,5') are hinge coupled to the fixed devices and to moving devices, and the other ends are hinge coupled to other links with connecting pins(4,4'). Rotatory fixing plates(10) are coupled to connecting pins positioned on upper sides. Insertion ports for coupling to the connecting pins are disposed on upper sides of the coupling plates, whereas coupling ports are disposed on lower sides of the coupling plates. Retractable safety display units(20) are made of wire sieves and are twisted and retraced by wires installed on edges of the display units. Combining holes(22) formed by riveting metal rings are disposed on upper sides of the retractable display units. The safety display units are combined to the fixing plates by inserting coupling bolts(30) through the combing ports on the safety display unit to the coupling ports on the fixing plates, and then tightening coupling nuts(31) to the coupling bolts.
