Ok so there is nothing "sexy" about this solution but... if you have kids and you want to leave the door ajar.
The Problem: I wanted to leave my bathroom door open a bit and let air circulate when done, but I just didn't want to lock-up my blades and put all my stuff away.
Solution: See photo's.

It works great - its cheap - and it's easy to do. Hope this helps someone who had the same issue.
