Set of transportable containers

A set of transportable containers, comprising at least two transportable containers, each one of the type of a suitcase, a trunk, a chest, a trolley case, and the like, and further comprising means for mutual retention of said containers, which are configured to be actuated in at least one stacking configuration wherein a bottom of a first said container is rested in parallel on a lid of a second said container in a specific mutual and active arrangement, said means for mutual retention being selectively deactivatable in order to allow a mutual spacing apart of said containers,

• said means for mutual retention comprising at least:
• a mutual coupling system, which is automatically activatable in said stacking configuration and is configured to obstruct the mutual spacing apart of said containers along a first axis, at right angles to said bottoms and to said lids, and a second axis, at right angles to said first axis,
• a selective locking element, which is automatically activatable in said stacking configuration and is configured to obstruct the mutual spacing apart of said containers along a third axis, at right angles to said first axis and to said second axis, said selective locking element being selectively deactivatable in order to allow the mutual spacing apart of said containers along said third axis,
• said selective locking element comprising a rocking tooth, articulated to either said bottom of said first container and said lid of said second container about a rotation axis parallel to said second axis, in said stacking configuration said rocking tooth being elastically kept resting on a respective protruding lip extending from another of either said bottom of said first container or said lid of said second container, in order to obstruct the mutual spacing apart of said containers along said third axis in at least one direction of mutual spacing apart.
