  • the lock latch guide is a guide device that guides the lock latch out of the door opening device when the door is opened.
  • a door opener device in which the lock latch guide is formed on the inside of the door opener housing cover.
  • the door opener is mounted with its door opener housing in the stationary frame of the door in such a way that the door opener housing cover is fitted in a recess in the frame outside the strike plate.
  • the lock latch guide is independent of the strike plate and requires the frame to be milled out.
  • a door opener device in which the lock latch guide is formed on the inside of the door opener housing cover.
  • the door opener housing cover is fitted in a form-fitting manner in the lock latch penetration opening of the strike plate.
  • the flat lock latch guide formed on the inside of the door opener housing cover ends flush with the surface of the strike plate.
  • the lock latch guide in this door opener device is determined by the arrangement and design of the door opener housing cover.
  • the lock latch guide is formed on the inside of the door opener housing cover. It has a curved course.
