Abstract:
A connecting system for modular furniture structures, in particular for writing desktops, tables, fitting-carrying wall structures, including at least one carrier upright element, to which other complementary structural elements are joined by means of connection means, wherein:the upright element has an external substantially square section with a plurality of sides, and on each side at least one longitudinal groove having a cross-section larger at an inside of the upright element, and shorter at an outer side of the upright element; the at least one longitudinal grooves give longitudinal corners of the upright element situated between them a quasi trapezoidal or dovetail shape, with a longer base turned toward inside the upright element and a shorter base turned outwards; said connection means being slidably mounted within said longitudinal grooves and/or along said longitudinal quasi trapezoidal or dovetail shaped corners and have a shape complementary with said longitudinal grooves and longitudinal quasi trapezoidal or dovetail shaped corners respectively; said connection means respectively having locking small blocks having a section matching a section of said longitudinal grooves, said locking small blocks being slidably insertable within said longitudinal grooves and being provided with locking means; â€œCâ€ -shaped clamps having a shape matching the shape of said longitudinal quasi trapezoidal or dovetail corners, said â€œCâ€ -shaped clamps being slidably engagable with said longitudinal corners and being provided with locking means; anchoring means made integral with said locking small blocks and â€œCâ€ -shaped clamps, for joining said locking small blocks and â€œCâ€ -shaped clamps to said complementary structural elements; said anchoring means each having a pin rod having a circular groove all around and a threaded section extending from an end of the pin rod for engaging with a threaded hole made in said trapezoidal section connection block and in a thickening made in a base of said â€œCâ€ -shaped clamp, so as to form said locking means for said connection small blocks and said â€œCâ€ -shaped clamps respectively.
