The lower linear guide (18) comprises one or more box-shaped channels (22), which can be buried below the walking surface (F) and comprise an upper wall (24) which is arranged to be coplanar with respect to the walking surface (F) and is provided with an elongated slot (26) oriented along the second horizontal direction (Y). Each guide means (20) consists of an elongated profile, oriented along the second horizontal direction (Y) and having an inverted T shape in cross section, comprising a vertical flat portion (28) arranged to slidably fit into the elongated slot (26), and a horizontal flat portion (30), which is arranged to slide within the box-shaped channel (22) at a predefined distance (D) below the upper wall (24).
