The present invention relates a double-latch closing system which may be advantageously applied to aeronautical devices such as trolleys, ovens, waste compactors, galley inserts and standard units. It comprises a pair of tongues (33, 37), each operationally connected to a handle (16a, 17a). One handle (17a) is provided with a locking and safety means (17′a) which acts on the other handle (16a). Particularly preferred is the use of said closing system for aviation trolleys made with ultralight composite panels having superior mechanical properties as regards aeronautical standards. The panels may be advantageously used to construct food and beverage trolleys to be used in the aviation sector. |
