Double flipper lever lock idea

[Josh K]

A standard lever lock uses one side of the key to lift levers into a "clear" position allowing the bolt to slide. What if we changed that to a two position bolt. The key is double sided, and the levers have sequential "clear" positions. You turn the key 90, bolt moves, another 180, the bolt moves again.

Let me know if I'm not making any sense.

I'm trying to think of that hardest lock to pick or bypass. I think that some sort of lever lock would be the hardest lock to open without a key. Disk locks would be another, but a complex (10+ lever) lever lock would be the most challenging I think.

Are you familiar with double bitted keys?

I guess not?

Double bitted lever locks are quite similar to what you described, have a look at these pictures:

They are standard on (at least German) safes.

I guess it's already been thought of.

Doesn't mean it's not a great idea

I'm trying to think of locks that are just plain hard to manipulate. I was doing some reading on payphone locks and noticed this article (http://www.crypto.com/photos/misc/wecolock/) and this picture:



The ratcheting mechanism used to lock the levers into place also intrigued me. Almost like permanently locking serrated pins. If over lifted you have to release tension and start all over.

Josh, next time don't put in the IMG tags when you're using a picture link from other people's websites


That's a very interesting locking system. I'd kill to have one of those in my hands

I was planning on replacing it with one I had uploaded to my photobucket account, but I can't seem to find the edit button.

Could you imagine a lock like this with 20 levers? It's possible with the thin levers that these locks use. Add hardplate protection for the drop in point and wow! Even worse would be a tempered glass plate instead of hardplate that was tied to half a dozen relocking devices randomly located on the safe's door.
