Abstract A double action hinge unit is disclosed which comprises a first base element, a second base element and at least two connection elements. Each base element has at least two upward extensions. Each connection element is hingedly connected with an extension of the first base element and an extension of the second base element. The double action hinge unit is changeable among at least three combination states. When the double action hinge unit is in a second combination state, the at least two connection elements are arranged side by side, such that the double action hinge unit is rotatable about a rotational axis at one side into a first combination state and is also rotatable about a rotational axis at the other side into a third combination state. |
