Mortise lock dual retainer holder

by **yono** » Fri May 11, 2012 2:25 am

again hello pals, here is another design and fabrication of mine, of a mortise lock enchance retaining hold in a mortise cylinder lock, to prevent the method of lock cylinder "force turning" by the use of plummer wrench or a vice grip. this additional feature in the lock and in the cylinder will really improve locking capability of any lock, high security or not. see the video. regards.

I don't see how this can work. How would you unscrew the cylinder in order to rekey the lock? For that matter how would you screw it in in the first place. Wouldn't an antiwrench ring do the same thing without the problem with rekeying?

very simple cledry, loosen the screws. i think you're not familiar with that kind of lock. the screws can be loosen, and the device moves back out of the cylinder canal and set it free. regards

No, I am very familiar with mortise locks.

The screw bridge that your piece is attached to doesn't move, it is fixed into two slots on either side of the lock case. So if your piece is rigidly attached to this how can it move to allow the cylinder to unscrew? That is why I am having trouble visualizing how this will work.

ah okey cledry knowing you are familiar with mortise lock then its worth explaining in detail.
youve seen that sargent retainer with two screws i have shown? notice another vacant hole in the middle? thats were i attached and loosely tappered long threaded bolt, (forming like a little neck at the end. this little portion has no thread) so that when you turn the threaded bolt its stays in place in that retainer screw base. and before i tappered that long threaded bolt to the retainer's base, i must first install that dual retainer into that threaded bolt (the dual retainer is also threaded to run thru the threaded bolt) so that, when i turn the threaded bolt, the dual retainer, will run back and forth because both are engaged in thread mess. the lenght of the dual retainer and the clearance that it can travel is very much considered, and its pretty cleared from the mortise cylinder body. sorry for this long story, but if it is still unclear to you, it will be my pleasure to post a drawing. regards

Let me make an analogy with bolts and threads.
A tiny thread can be easily sheared, a deeper one can't. That's the concept behind yono idea.
That said, a properly installed mortise is flush with the door and doesn't protrude enough to be grabbed and turned with a plumber wrench. I guess that there are many mortises poorly installed which could benefit from a deeper anti-unscrew groove and bolts.

Hope this helps you visualizing the concept. Looks good to me but I can be wrong.

Cheers

OK, now I understand. It is a clever idea, perhaps worthy of selling to a manufacturer of mortise locks.

I can't see locksmiths using this except perhaps on new installs which aren't commonly done by locksmiths. Mortise locks generally are done at time of buildout by contractors who would make a right mess of disassembling a mortise lock, or rather putting it back together. I don't see many attacks by pipe wrenches except on Adams Rite style locks and generally an anti-wrench ring is added to protect against this sort of attack.

Here's a photo I took today of a typical mortise lock. As you can see the cylinder is housed in a tapered ring which cannot be grasped with a pipe wrench. This is the easiest way to accomplish anti-wrench protection as no lock disassembly other than unscrewing a mortise cylinder is required. In the example shown here, Falcon provides the tapered ring as a default.

The hollow one appears to be a deadbolt one and is missing the inner hard liner. The Falcon on I showed is solid BTW.

The detailed images explain it well, thank you.

BTW, you have a typo, "pork" I think should read "fork".

by **yono** » Sun May 13, 2012 12:32 pm

was it? thanks a lot cledry, its fork then. regards.

@yono:

I can see how your idea would protect against turning type attacks, however without more work it won't do anything at all to defeat pulling/yanking type attacks...
