[FIRST] Lock design

[CYANOPHOSPHATE]

I was thinking of a hybrid of a key and a combination lock, where a key must be inserted, and then the key is turned like a combination lock, using three wheels behind the key, or belt driven, like a turntable, in that it is turned, and having the combination part above, to save space. What does everybody think?

If you go to YouTube and watch this video http://www.youtube.com/watch?v=xWjX7SMHIJ8, about three minutes way through it, you will hear him talk about a lock designed as you describe. I don't know the spelling, but he says the name of the company - phonetically, it is spelled sezahm, and the locks were made for use in Poland.

Squelchtone probably has a link to the manufacturer, patent info, pictures of the lock and key, and who was cleaning the washrooms next to the production floor on Tuesdays, Thursdays and Fridays. Squelchtone's knowledge never ceases to amaze.

By the way -no, that is not Squelchtone in the video.

Ahem.

That's Schuyler Towne's TEDx talk in Somerville you linked to. Schuyler and I are both fans of the SEZAM combination cylinder. It's worth noting the of the lock name SEZAM means Sesame as in "Open Sesame" the magical phrase that is used to open a cave in the story Ali Baba and the Forty Thieves (from the collection of old Middle Eastern stories as talked about here: http://en.wikipedia.org/wiki/One_Thousand_and_One_Nights).

Here's a pic of one:

I knew you wouldn't let me down, Squelchtone! You don't disappoint.

@CYANOPHOSPHATE:

What you are describing does exist, it is called the Robotic Key System or RKS...

Han Fey wrote a paper about the concept several years ago...

Here is a link to a thread on LP101 about it...

Neither the SEZAM nor the RKS lock the combination entry unless a key with specific bitting is used.
There are safe lock dials that can be locked (typically with simple cam locks).

However I'm quite sure that locks where the turning of the key dials a combination have been made, I just can't think of an example right now.
