Modular sectional structure

Abstract

Modular sectional structure, particularly suitable for creating furniture pieces, furniture complements or the like, for example tables, small tables, shelvings, expositors, and the like, or for the creation of open or closed areas, for example stands, boxes for fairs, exhibitions, and the like, or for the creation of partition walls, and the like, characterized in that it comprises vertical uprights, each of which is provided in at least one position of at least one lateral fitting for the preferably removable connection of at least one horizontal transversal member, by which it can be connected with at least another vertical upright.

We claim:  
     
         1 . A modular sectional structure, particularly suitable for creating furniture pieces, furniture complements or the like, such as tables, small tables for offices, shelvings, expositors, and the like, or for creating open or closed areas such as stands, boxes for fairs, exhibitions, and the like, or for creating partition walls, and the like, comprising vertical uprights ( 101 - 117 ) each of which is provided in at least one position with at least one fitting ( 200 ) at right angles therewith for the removable connection of at least one horizontal transversal member, by which it can be connected with at least another vertical upright, characterized by comprising a connecting joint between said fitting ( 200 ) at right angles with an upright and a transversal member ( 302 ), said joint comprising a first tubular joining portion integral with the upright and a second tubular joining portion, coaxial with the first one and integral with the transversal element, as well as an expansion pin ( 340 ) partially insertable with the ends thereof into said tubular portions ( 200 ,  302 ) and radially expandable by means of a screw ( 341 ) for opening complementary portions ( 340 ′,  340 ″) thereof and longitudinally matchable and screwed in accessible way in a median collar of the expansion pin ( 340 ).  
     
     
         2 . A structure according to  claim 1 , characterized in that said connecting joint comprises a joining pliers ( 342 ) with a pair of jaws ( 342 ′,  342 ″) which can be tightened and blocked, for instance to the upright ( 101 - 117 ), or to perimetrical bars of the transversal member, by means of a tightening screw ( 343 ), at least one of the jaws being provided with a tang insertable in a tubular joining portion for instance of the transversal member.
