An expandable travelling case comprises a back panel, a flexible jacket, and a tensioner. The case can be expanded by moving the expansion arm to an expanded configuration. The expanded configuration involves the tensioner bracing or pushing against the flexible jacket in cooperation with the back panel of the case. The tensioner is therefore compressed between the jacket and the back panel in the expanded configuration. This provides a tension fit for the flexible jacket. There is also provided a retention means and suitable component to maintain the travelling case in an expanded state. |
