摘要： A revolving door system has a central axis defining a center shaft and three wing hangers rigidly joined and extending in a equidistant spaced apart relationship about the center shaft's upper portion.A pair of facing substantially semicircular walls, spaced apart to define regions of ingress and egress, partially surrounds the wings and shaft on opposite sides.The system allows free passage of persons in an authorized direction while preventing, and driving out, intruders attempting to pass in an unauthorized direction. If an intruder enters the system in an unauthorized direction, the door stops before the intruder has free passage to the other side, reverses direction and forces the intruder back toward the entrance. In one configuration, the door then rotates in its forward direction to permit the authorized passenger to escape the system, but not far enough to allow the intruder to pass. In another configuration, the reversal of the door allows the passenger to escape from the side in which it entered. The system then recycles alternately reverse and forward again until the intruder is convinced to leave the system or the authorized passenger has escaped, whereupon the system returns to its normal stop position and the intruder is prevented from passing.
摘要翻译：旋转门系统具有限定中心轴的中心轴线和刚性地连接并围绕中心轴上部以等距离间隔的关系延伸的三个翼架。一对面对的基本上半圆形的壁，间隔开以限定入口和出口的区域，部分地围绕相对侧上的翼和轴。该系统允许人员在授权方向自由通过，同时防止和驱赶入侵者试图通过未经授权的方向。如果入侵者以未经授权的方式进入系统，则门将在入侵者自由通过另一侧之前停止，反转方向并迫使入侵者返回入口。在一种配置中，门然后沿其向前的方向旋转，以允许授权的乘客逃离系统，但不足以允许入侵者通过。在另一种配置中，门的反转允许乘客从其进入的一侧逃离。系统然后再次循环回转，直到入侵者确信离开系统或授权乘客逃脱，于是系统返回其正常停止位置，并且防止入侵者通过。
