I actually tried this with a loose handle recently and it didn't fit!

Thanks Malcolm

A other myth busted

[JKernwerk]

I think these are door handles with an extra feature to block the door with a beam.
In my opinion it is easier to close with two hands on the door.
The extra L-hook is only one the inside, not sure it that is the same with all doors.
No real proof so it is just a hunch.

Is there an archive document, photo or other book that illustrates the use of this hook?
Otherwise, the idea of a support formed by the hook and the handle, or the more general idea of a direct link between the hook and the wrist cannot be excluded.
Likewise, other hypotheses are possible as JK has just mentioned.
We can also imagine a hanging system to block the handles, or the door, etc.

I'm not convinced of the door handle theory either. It's not fixed to the door, and would easily fall off.

[Marc Mentel]

I am also not convinced by the support hypothesis.
But I think there may be a relationship between the hook and the handle, or a relationship between the hook and the handle function ie closing the leaf.
Indeed, we can notice that the hook is always near a handle and that its position relative to the handle is always the same.
Also, we could think of the hook as a simple half handle to pull more efficiently if needed.
The simplest solutions are often the best!

When the handle is in open position, it's much easier to close the door with the hooks.
On the outside of the door is a ring for the same reason.

Sorry but this makes no sense to me.
The "half" handle is not easy and comfortably to pull.
And why don't make a ring in the inside to close it more easy of this was an issue?
By the way, the ring on the outside is very easy to remove on alot of the doors, only attached by a M10 or M12 thread. Some like on the above picture were welded.
The doorhinges were fitted with copper/brass rings, and would be closed very easy back in the days.. sometimes even now some examples in dry bunkers close very easy.
It must be for hanging/attaching something on it..

Placing a closing bar on it dont sound logical to, then they would have put the small hook further away for more stability?

That detail in the sketch, the place to hang it?

Maybe to leave the door lock lever, that they cannot be opened from the outside.

Thank you Luda, that fully supports the theory!

[Marc Mentel]

Thank you Luda for this document !

Thanks! Tim try it out in one of the museum bunkers.

Thanks! Tim try it out in one of the museum bunkers.

I tried this recently on a 434P01 and it didn't fit
And thank you for the info on the red ring painted on doors AvB!
