We’ve seen it before, the universal sign of “I have company, go away” signal. Often taking form as a tie around a doorknob or the potted plant flipped over. There’s got to be a more high-tech way. The Doorknob Condition uses an innovated pulley system that makes the knob on the exterior recess inwards when pulled from the inside. Without a knob to use, there’s no way to get it. Sure it could be great for security but who are we kidding? We know exactly how a doorknob like this would be used. Too bad it doesn’t have a little timer to indicate when to come back.

I would like one Because the government does’t like them.
Is there any keycard or some kind ??? What if the door accidentally closed? Would you be able to get in?
Awesome!!
I could be incorrect of course, but judging by the hole near the base, there is a key unlock of some sort?

It’s an remarkable paragraph designed for all the online people; they will take benefit from it I am
sure.
I want one.
Are you a firefighter? They are trained to open doors that have locked deadbolts. I know this because both my parents were firefighters for a number of years. They also have specialized tools for the express purpose. I’d be more worried about how you would replace the broken door than about the firefighters protecting you.
Perhaps you are merely looking to complain about things that are clearly awesome? Maybe you’re complaining because you prefer the ‘good old fashioned doorknobs’. Relax… they aren’t going anywhere for at least 30 years due to people like you. On the other hand, yes, compliance with regulations is very important for widespread adoption.
