摘要： A sliding replacement door is made of an extendable covering and a mechanism for extending the covering into the doorway and retracting it therefrom. The extendable covering includes a pair of plastic or vinyl sheets on respective spring-biased rollers, analogous to a window shade. The free ends of the sheets are attached to a movable, vertically oriented bar. The rollers are spring-biased to cause the sheets to normally be wrapped around them, and thereby pull the bar towards them. The extension mechanism causes the bar to move horizontally in a direction away from the rollers, to thereby unroll the sheets from the rollers against the spring bias, and extend them into the door opening. The extension mechanism can be a motor-operated scissors mechanism.
