  • Out EP 2 395 192 is a multi-leaf fire door according to the preamble of claim 1 is known.
  • fire doors must be approved by the building authorities.
  • the manufacturers of fire doors with a new design must perform standardized fire tests that demonstrate the fire protection properties.
  • the fire doors with frame and door are installed in a test wall and installed on a test furnace in order to heat them from the one side over the prescribed period of protection.
  • a class T30 fire door must withstand this for at least 30 minutes. If there are flames during the fire test, or if the fire door on the side facing away from the fire becomes inadmissibly hot, then the fire test is failed. An approval is only available upon proof of a passed fire test.
  • the respective door is held on the one hand by the hinges and on the other hand only by the catch. It should be noted here that the fire doors must be in the unlocked state, purely by holding the catch the fire test.

  • the unilateral rear handle serves to support each other of the door and creates next to the catch additional support points for the door. In this way it is possible to use a standard lock instead of a special lock. In addition, the use of only one rear grip requires less Manufacturing steps for producing the door, since at least one projection is not needed. This also consumes less material during production. The production of such a fire door is simplified compared to known fire doors and cheaper.

  • An improved behavior in case of fire can be achieved by providing the rear handle in this central shock area, since the largest forces due to the Lever effect of the door wings act.
  • the rear handle can in this case effectively absorb these forces and prevent the formation of a gap in the center joint area, even if the fire door is not locked and is held only by the catch.
  • the rear grip in the closed state extends along the entire extent of the fire door wings in a direction parallel to the vertical axes.
  • a continuous rear handle improves the behavior of the fire door considerably, since the resulting forces in case of fire are distributed to the entire fire door and not punctiform act.
