Sidebar Pressing Into Pins.

[Microwarrior]

I have seen plenty of locks with sidebars that interlock with grooves in pins in various ways when the plug is turned. However, I have never seen one where the sidebar is not pressed into the pins directly by the turning of the core. It looks fairly easy to have the sidebar push into the key pins with spring tension and would seem to come with many security benefits. Does anyone recognize something similar to this design and if so, where? Also, I have included a JPEG illustrating and detailing the idea.

Have you seen the "Gold Atom" lock?

Here's a German post by Oli D. (the lock impressioning guy)

The locks have the Chinese Brand 金点原子 / Jīn diǎn yuánzǐ "Gold Atom" / "Golden Point Atom" / "Gold Point Atomic"

Please note that your image is 1,280px × 720px and that 800x600 is recommended so image clipping doesn't occur when using the inline image [IMG] tags

if an image is bigger, we recommend using the [URL] links instead, or a smaller thumbnail linking to the larger graphic.

That looks like exactly what I described! I don't understand why these type of locks are not used more in the USA. Thanks for the information!

Thanks. I will keep this in mind.

This type of design is actually quite old. The oldest lock I ever found with that design was patented by Briggs and Stratton in 1934, and many more followed. Ilco patented one in the 50's and GM used Briggs and Startton's design in their cars for a while. The only manufacturers that I know of that use this idea now are Gold Atom and Yuema.

Regarding current implementations in China:
While Gold Atom uses pins, the Yuema designs that I have seen use wafers - and some also have a core that's 360 degrees free spinning, if the sidebar can't enter the gates in those sliders. Quite a nice design.
However, I wanted to add that there are lots of other Chinese brands currently that use sliders with a sidebar that is spring loaded towards the inside, often also free-spinning cores. One can find them (and many other interesting locks) e.g. on taobao or tmall.com,
DENAITE http://dntlocks.com/ would be one example.
I acquired a number of such examples and will try to bring them to LockCon in the Netherlands this year.

In case of a pin tumbler/wafer lock with reverse sidebar and a tight paracentric vertical keyway is a sputnik tool the only option to open it?

I know that this question was asked before but what is the drawback that the reverse sidebar is practically non-existent in a good quality western locks? The only modern examples that come to mind are Kwikset Smartkey and Master Lock M532 but these are far from decent.
