    • A retractable barrier includes a rollup or otherwise retractable panel that can extend between two spaced apart support members. When not in use, the panel can retract onto one of the support members to permit passage. The barrier provides substantial impact resistance by having the reactive force of the impact transfer directly between the barrier's retractable panel and its support members without having to rely on the strength of the panel's take-up roller or the strength of the roller's anti-rotation mechanism. This can be accomplished by having a slot-engaging stop member mounted directly to the panel itself. The stop member is preferably a pipe, rod, bar or some other vertically elongate member that can broadly distribute an impact reactive force over the height of the panel. In some embodiments, the barrier can be set for various doorway widths by simply repositioning the stop member's location on the retractable panel.
    • 可收缩的屏障包括可在两个间隔开的支撑构件之间延伸的汇总或其它可收回的面板。 当不使用时,面板可以缩回到其中一个支撑构件上以允许通过。 屏障通过使冲击的反作用力直接在阻挡件的伸缩面板及其支撑构件之间传递而不必依赖于面板的卷取辊的强度或者辊的防旋转机构的强度,而提供了显着的抗冲击性。 这可以通过具有直接安装到面板本身的狭槽接合止动构件来实现。 止动构件优选地是可以在面板的高度上大致分布冲击反作用力的管,杆,杆或一些其它垂直细长构件。 在一些实施例中,可以通过简单地将止动构件的位置重新定位在可伸缩面板上来将障碍物设置为各种门口宽度。
