No knock lock / Public Lavatory Lock

No knock lock
No knock lock

There are two embarrassing situations which often happen when females use the public lavatory. One is when people knock at the door - since it is not always obvious that it is already occupied - and it is not really a good time to reply. The other one is when there are no hooks to hang bags on. Thus a proper lock is important for public lavatory doors. When you lock the door, the handle will be retracted at the same time as to indicate that there is already someone in it. The other way round, when you unlock the door, the handle will show up on the surface again.
