BUMPKEYING/LCKPICKING-Trigger lck pin( redesigned)

[yono]

Thanks to Snowyboy,Datagram,Engineer and Raymond for their contribution and supplied info. I redesigned my Bmpkey trigger lock pins and simplified the application.it will also a defense against lckpicking. In this proj. I fucos on ordinary mortise cylinder, to have a defense against walk around thieves. In this drawings i showed detail position, in "normal and triggered position of pins.

You're starting with an already weak platform. Mortise cylinders have many weaknesses.

The M&C Antiklop concept is quite similar (search google for m&c antiklop)

There are flaws in erverythign but keep working the way you are and you'll come up with something

[unjust]

i like the theory, would a sidebar sort of set up be easier to drop in than a single pin?

[yono]

To N2oah- your right friend ordinary mortise cylinder have many weaknesses..I reduce it with minus two. bumpkeying, and lockpicking
To Unjust-- the side bar idea is very good, but the complexity of installing it by a locksmith is seem not practical.
To 5th corps, thanks for the encouragement, locksmithing is seem an enlightenment for me. especially if i do something better.

Also what happens if you're not home when the break in attempt happens? The trigger pin is stuck and you can't get inside to remove the set screw for the safety pin.

Or maybe I am missing something?

It is a good idea, I think eventually you will get a good working setup. Keep it up!

Hi Yono - I think you have managed to achieve what you set out to do - Well done!

I see no reason why this would not work. An electric lockpick fitted with a deep hook just might be able to vibrate the locking pin enough that the pin locking it in place might just be persuaded to let it back in and free the cylinder again. Properly designed, that could be negated as well.

The lock as it stands, is strictly a one-shot lock. Once the locking pin is trapped, the whole lock is written off. Great for high security, but perhaps open to people to "vandalise" by purpously bumping them, so they are destroyed and costing the owner a lot of money.

If you could make it so that the trap pin could be retracted again, but ONLY by opening the door and removing the lock from the door to "reset" it, then I think you might have a commercial product.

Note that my idear of an internally-resettable trap pin will only work if the lock is fitted to a room with two doors, or some othger means of entry. If the lock is fitted to a vending machine, or a room with only one means of entry, it will still need to be destroyed if it is triggered through a genuine attempt to gain entry, or through vandalism.

You've done good work so far on this! It's fun watching it develop...

I think me made mention of a set-screw in the back that would be able to reset the trapped pin. I wholeheartedly agree though; I love the idea's Yono is dropping left and right.

Great job Yono, keep up the good work!

Nice work. Maybe someone with a milling machine can try to make one

My cutaways are doing so well (only sold 4 so far and made near on £200!) I'll be getting my own mill! I can make prototypes then

Thanks for the creds Yono

One more idea for the lock pin would be to have the ability to retract it from the other side of the cylinder. So when the lock alerts you to the fact someone tried to pick, you can easily have it reset by the locky you call out. Just another idea thrown in there

Oh yeah, get hold of a copy of Autodesk Inventor Pro..... will save you messing about drawing


I made this on my first attempt at using the program

congrates for the blooming business snowyBoy. and thanks for the much needed info. The idea of an easy access at the back of the mortise cylinder is got to be figured out, due to the blocking of the Cam on the window of the safety pin when it is in triggered position. regards.

Have a look at this

You could have the hole here and still design the pins to lock as you want them.
