Detachable hinge for foldable separation shelf, has bar and opening that are dimensioned such that bar traverses opening in folding position in which section is placed with preset angle with respect to another section to dislocate sections

摘要

The hinge (10) has a shaft (70) for housing an articulation bar (42) of a hinge element (36) to articulate a parallelepiped section (40) of the element to another section (68) of another hinge element (38). The shaft has a main opening (72) extending on an angular section of the shaft. The bar and the opening are dimensioned such that the bar uniquely traverses the opening in a folding position in which the section (40) is placed with a preset angle with respect to the section (68) for dislocating the section (40) from the section (68).
