Help With Fastener/Fixing Terminology

[charliegolf]

I know what I want, but not what to actually search for.

Picture an extending pole (like for painting etc) with spring button 'locks' that pop into place to stop the inner tube sliding.

I have also seen fasteners that go outside the outer tube- they look like a sprung 'see-saw with a pin that goes into the tubes, rather than popping out.

I'd like to make up a rectangular section 1m long, with an inside extender that comes out about 450mm and locks.

Any idea for the item term to search for? Ta.

The device you mentioned would normally be purpose made for each application.
You might be able to use something like this .?

They are used a lot to adjust leg length on crutches, invalid chairs, disabled living furniture.

I don't know what they're called but I imagine they are easily lost so spares must be available

Try a disabled living shop.

Think OP wants external clips not internal ?

Fair comment, I can't picture what he means though.

That's an interesting device.....CG is thinking of rectangular section material (I think) which throws up a few difficulties.
I think I'd be looking for suitably telescoping material first.

All I can imagine op wants is like this with some clips like John linked to.
Edit ,a more robust version of what BG posted are clips like i have on my larger towers

Full Project Disclosure lol.

I want to 'mount a projector on a stick', which lives horizontally behind the sofa. Out of use, out of sight. As with most sofas, there is wide space behind at the bottom, narrowing with the rake of the seatback. I would slide it out horizontally, far enough that it will rotate 90 degrees to the vertical, missing the seatback, and lock. Hence the need for a locking mechanism. What I want to avoid is 'crawling' under the damn thing to unlock or lock it.

Pic en route.

It's not the answer to your question, but what about a folding shelf?
You could even disguise it, I like this idea: https://www.pinterest.co.uk/pin/32158584811626677/

Fair point, but there's a picture on the wall that we really like. At the mo, we drag all the bits out and use the coffee table for the projector. It's a faff.
