escalier limon découpé

escalier limon découp é

There are a number of references to this on Google, but even with photos I cannot work out what the 'limon' of a staircase is.

Can anyone help?

le limon d'un escalier est le support des marches. Il faut comprendre: escalier à limon découpé.

Thanks very much, Little One, that would seem to be a "cut stringer".

Stringer, Stringer board or sometimes just String
The structural member that supports the treads and risers. There are typically two stringers, one on either side of the stairs; though the treads may be supported many other ways. The stringers are sometimes notched so that the risers and treads fit into them. Stringers on open-sided stairs are often open themselves so that the treads are visible from the side. Such stringers are called "cut" stringers. Stringers on a closed side of the stairs are closed, with the support for the treads routed into the stringer.

Yes, you are right. I have checked some pictures of "cut stringer stairs" and apparently that's the same thing as "limon découpé".
