This is super clever, but I bet some of its potential applications conflict with egress safety requirements/laws.
(If a door is part of an exit route, you probably can't require a key to open it.)
- michaelmior 7y agoIt seems like you could have a similar system which also has some type of internal lever to release the lock although I assume this wasn't part of the original design.
- Someone 7y agoNot really. When you can open it from the inside without using a key, you can then also leave it open without that key being inserted into the door, if necessary by propping up something to the door to prevent it from closing itself (from what I understand, you could even use the door’s bolt for that; if you close the bolt while the door is open, you can remove your key, and the door can’t be closed without a key) I doubt that’s theoretical. Kids playing in the garden and on the street could easily use that ploy.
- tragiclos 7y agoThat would defeat the purpose of the key design, which is to ensure that you lock the door behind you.
- gumby 7y agoGood point, but I doubt those rules existed anywhere in 1912 when this key was invented.
- mongol 7y agoMakes me wonder: how are prisons handling fire safety?
