A rolling door is provided with a flexible door panel which can be wound upon a winding shaft pivoted above the door opening and provided with a drive. On the bottom end of the door panel, a stop rail of length less than clear span between side sections limiting door opening, is provided at two ends with fastening for wires running over pulleys supported in a bottom region and bracing the door panel. In the side sections, slide-like blocks are guided vertically slidably, detachably connected to the ends of the stop rail by a retainer and provided with breakthroughs for the wires running from the pulleys in the bottom region to the stop rail. To restore the rolling door to operation simply and where possible even automatically after a crash, the retainer is constituted by locking devices which release the stop rail in the event of force acting thereon from the side and which, when the blocks are pressed on from above, again interlock the stop rail and blocks. |
