Securing lock for aircraft trolleys in turbulence

[摘要] An apparatus for preventing trolleys of aircraft during turbulence from leaving the floor of said aircraft includes a securing lock installed on a trolley of an aircraft for sensing the gravity on the trolley. Control is provided to prevent the action of the trolley from leaving the floor of the aircraft during turbulence. An actuation of the securing lock occurs for preventing the trolley from leaving the floor of the aircraft during turbulence. The securing lock includes a blade locking system for preventing the trolley on an aircraft during turbulence from leaving the floor of the aircraft by holding the trolley onto the seats adjacent to an aisle with extendable blades.
