Speaker of books (Machine-translation by Google Translate, not legally binding)

摘要

A book exhibitor, characterized in that it comprises a vertical shank capable of rotating freely on its axis with respect to a support base, to which it is fixed by its lower extremity, in whose shank a series of plates are threaded through corresponding central holes. Rigid that constitute the shelves, each of whose plates is retained in correct position with respect to the shank, by means of a corresponding washer-type that is rigidly fixed to it, all in such a way that all the set of said plates can rotate in solidarity with the stem with respect to the base.
