For the climbing house I built for the children, I want them to be able to lock themselves in but not get locked in. How can I attach a shaft that sits in both knobs?
My problem
Pencil drawing of a mechanism diagram showing side and view angles with arrows indicating movement, related to lock design for a children's climbing house.
My first attempt, epoxy will probably work.
Wooden door handle with metal spindle, designed for a children's climbing house. Used to prevent lock-in by allowing locks on both sides.
I have the same function on the sauna door but can't see how they're attached.
Does anyone have a tip?
 
One option might be to drill a hole in the wall or door large enough to pass through a round bar, a few extra mm so that the bar can rotate. Then screw a piece of wood at each end...

Like my last picture shows?

No, I was thinking like a U - but maybe you need an H? But it's obviously equivalent, though a round rod instead of a bolt then - thought it would be easier to attach.

What is the problem? The knob works perfectly as it is, doesn't it?
Though maybe you should have mounted it before you glued ;)

But an improvement might be to make the knob a bit longer in one direction from the bolt? It would then be front-heavy, and you could mount a screw as a stop in the door, or the wall, depending on where you mount the knob.
It would then have a function reminiscent of a "real" door handle.
 
Borrowing the thread a little. :). Are there any tricks to prevent the wooden blocks from starting to spin after a few years on a classic knob like this?

Maybe there is something ready-made (bolt etc.) to buy?

Another solution could be to use a square metal rod and glue it in place. In my sauna, I've had to tighten the knobs as the wooden blocks dry over time, so now they don't sit parallel.
