How does an adjustable device work?

[cadounette]

hello everyone
i am doing my intern and am told to come up with a design for a device adjustable in height and width.
i have been looking on the internet and found some designs that might work but the problem is i don't know exactly how does they function.
for example this design : http://www.rdbureau.com/p-184.html

so I'm hoping that someone can explain to me about how it operates.
thanks :)

Hard to tell from the picture and the French explanation, but it could use the click tabs that you find on EZ-Up pop-up awenings. Are you familiar with them?
