  • the known roller door has a flexible door leaf for closing building openings in cold stores, the door leaf being guided laterally in m guides. With such a gate, vehicles may pass through before the gate is fully opened. Greater damage to the door and to the vehicle can be avoided if the door has flexible guide elements that release the door in the event of a side impact.
  • laterally resilient guide elements on the lower crossbeam which yield when a force is exceeded.
  • a disadvantage of resilient guide elements is that the spring travel is limited. With particularly strong deflections, irreversible damage to the gate occurs.

In particular in the embodiment with screw, this can be used for Restoring the initial state can be solved to enable easier engagement of the holder on the machine element. Then the screw is tightened again until the desired contact pressure is reached.
  • two latching elements are provided at the ends of two legs of a V-shaped holder of the latching connection and a spring joint is provided at the connection point of the legs, which pulls the legs together or presses them apart with a predetermined force.
