Hi to everybody,
Today I’ll show my new design. This design is the mix between a normal stairway and a ladder, in fact, as you can see, is a folding stairway.
But when the stairway is folded, it’s almost invisible, andit takes up less than a normal ladder.
You have the advantages of one stairway when you must go up and go down, and you have the advantages of a ladder when it’s folded, it takes up very small space, no more than a big-picture hanged in a wall.
Now begin to unfold the stairway, the treads begin to rotate to his position.
Finally, the stairway is completely open, and all the treads are horizontal, parallel with the floor.
All the treads are the same piece, but is not joined by the same way.
The treads are joined by rotated ones from others.
The sides of the stairway have crevices and slotted to make possibly the movement of the stairway.
High slop. (35º)
Big step space.
Not as solid as a fixed stairway.
