- Turn the yellow and beige frames to fold or deploy the ladder.
The yellow frame, blue steps and pink bars form a parallelogram mechanism.
There are V-shaped grooves on the back of the top step to lock the ladder in the deployed state.

Thank you for always sharing ur designs and for inspiring us..
Sir, I am in difficulty to make a contraption and I couldn't find a solution among your designs. Is is possible for you to help, please? If so, how can I send sketch to explain the idea.

@@thang010146 I sent it. Thank you.
Being completely honest, i enjoy seeing your designs and watching them work
But some of them (this one specific) I worry how practical they are because i imagine the force vectors and feel like they would be inferior to designs more commonly in use, such as this step ladder
Just my opinion and no disrespect meant
Despite my criticism, I hope you keep up the good work
Any constructive criticism is welcome.
You may misunderstand the design
When unfolded, all the steps are resting on the top step through the pink linkage. It's not resting against the green linkage.
So when a person climbs the ladder, the green linkage doesn't take the load.
