To cause a door from being forced open or broken to gain access, a safety door comprises a central actuator and a plurality of bars radially extending at spaced apart locations from said central actuator sufficient in number and spacing to reinforce substantially the entire door. The central actuator is pivotally mounted within the door and each of the plurality of bars has one of its ends pivotally mounted to the actuator to cause the bars to be retracted or extended by rotation of the actuator. There are at least four bars with at least one bar extending in each of the four sides of the door framework.
