Russian Innovation: State-of-The-Art Door Chain

by M Dee Dubroff

According to news sources, Lebedev Studio, which was founded in 1995 by Artemy Lebedev, lives by its motto, “design will save the world”. All of its creations are beautiful and unique both in concept and execution, and now Lebedev Studio has tackled the issue of personal security in a very creative and attractive way. The Lebedev Defendius Door Chain Lock stands out from all others of its ilk, defying entry because it is a door chain with a labyrinth, which is only long enough to reach the end of it. Personal security and a few fun moments seem to be the message here, and it works!

If you are not fond of labyrinths and are often in a hurry, this isn’t likely to the thief-resistant gadget of your dreams. It does take time to open a door with this type of lock on it, but according to many, it is quality time. The Lebedev Defendius Door Chain is constructed of 100% titanium alloy and its makers claim that it has proven to be resistant to approximately 700 pounds of force (equivalent to two and one half and possibly three obese burglars).

The Lebedev's Door Chain is also more firmly fixed to the surface of the door than any other similar products. It is fastened with ten screws as well as two extra screws for good (and extra good) measure. The titanium alloy composition renders the lock very tough and able to withstand extreme temperatures. It is also very lightweight. If you haven’t already suspected, titanium alloy is also an extremely expensive material, which up to now has been utilized, mostly in military applications. The price of the Lebedev Defendius Door Chain has not been revealed, but one can only use one’s imagination. As millionaire financier, JP Morgan used to say, “If you have to ask, you can’t afford it.”

Well, I know that I probably can’t.

How about YOU?

Вы правда подумали, что Лебедев это в действительности продает?

That's been around for a while now. Look up Defendius door chain.

700 pounds?

Submitted on April 12th, 2009 by Anonymous

Thats nothing. I weigh 170 lbs but running full speed into a door I'd easily get an impulse spike well over 1000lbs. Impact strength is measured in joules, or newton seconds, do you know the value for this? Be interesting to know.

Hi there-

I didn't know that.

I subscribe to a feed and the information came to me last week.

Thanks for telling me.

I don't know the value you are asking about, but you have to admit, it's a cool chain, no?

Thanks for your comment.

Interesting idea, for sure,

Submitted on April 14th, 2009 by Chris Weiss

Interesting idea, for sure, though I doubt it'd actually be any more effective at keeping someone out. 700 lbs. is a lot of weight but not that much force and I would think someone running into the door or kicking it would be able to break this open without much more effort than an average chain. Very interesting design though and the labyrinth would be fun--at least for the first time or two!

Interesting idea

LOL
