Description

TECHNICAL FIELD

The present invention can be placed in the field of the building geometry solutions applicable to a big number of industrial products.

It consists in a joint building system to assemble and to shut the six walls of a box parallelepiped at the minimal possible condition to split at least one wall of the structure in at least two plates.

From a practical point of view, the flexibility of the building system allows to create countless artefacts, also complex, which in the most of the cases are built up with only seven elements simply jointed together.

This system allows to joint together several structures, then it can be considered also a nodal joint for building complex structures.

Finally a particular characteristic of the invention, allowing to assemble twelve plates all perfectly identical in a cube, could pertain to other fields of belonging.

BEST MODES FOR CARRYING OUT THE INVENTION

The generic minimal structure, built up with seven plates, is suitable for building many kinds of boxes and countless artefacts.

Among the possible configurations of the present invention the followings are the preferred.

• • Structures in which the secondary plates are complementary to their primary plates; so all single and multiple walls have an equal thickness and all grooves have an equal width, FIG. 18 (a,b).

This solution has an aesthetical character.

• • Structures wherein the secondary plates are supplementary to their primary plates; so all primary plates have an equal thickness, the multiple walls are thicker than the single walls and the grooves receiving multiple walls are wider than the other ones, FIG. 18 (c,d).

This practical solution is suitable for small tables, trolleys, etc., wherein the secondary plate is a glass shelf, FIG. 40.

• • Cubic structure, built up with twelve perfectly identical grooved plates and coupled pair wise with matching ungrooved faces, FIG. 37.

This configuration is suitable for a witty game.

• • Cubic structure, built up with twelve perfectly identical plates, provided with folds shortened at their edges in measure equal to their depth, coupled pair wise with matching unfolded faces, FIG. 38.

Also this configuration is suitable for a witty game.

• • Stackable structures wherein plates edges are reduced in measure equal to the grooves depth, FIG. 39.

This configuration allows stacking several structures.

• • Structures containing frame plates, wherein the grooves are jointed also on the internal ribs of plates, and wherein at least two secondary plates are employed, FIG. 41.

This way is suitable for trolleys, showcases, bookshelves, etc.

• • Structures having a primary plate provided with an access hole and with a secondary plate working as a sliding lid, FIG. 42.

This is a practical solution for boxes.

• • Structures having an access hole and a blocking lid obtained by the two, one smaller than the other, holing rejected items of the two plates of the multiple wall, FIG. 43.

Also this is a practical solution for boxes.

• • Multiple walls supplied by a definitively fixing device like a fly spring, FIG. 44, a padlock, FIG. 45, a clip, a screw, etc.

These are useful complements.

• • Nodal structure wherein walls are extended beyond the shut box part, FIG. 46.

This configuration is suitable making chairs, armchairs, etc.

• • Multiple nodal structures, composed by many structures joined together by the extension of the primary plates, provided by other couples of grooves, employing several secondary plates, FIG. 47.

This configuration is suitable for building complex structures.
