ABSTRACT:
BACKGROUND OF THE INVENTION
Aircraft passenger cabins must be insulated from vibration and noise caused by the slip stream of air and engine and propeller vibration. The walls, ceiling and floor are insulated by the use of insulated panels surrounding the cabin. Aircraft cabinets are mounted to structural members of an aircraft fuselage; however, their mounts must be insulated to prevent the vibration and exterior noise from entering the passenger area. In the prior art, cabinets and partitions have numerous shock-mounted attachment points, all of which take much time to mount and remove.
SUMMARY OF THE INVENTION
The present invention provides a quick disconnect mounting system for cabinets and partitions which entails only the removal of one or two bolt fasteners on the bottom of the cabinet and a pair of retractable pin fasteners on the upper portions of the cabinet, with an optional retractable pin fastener in the center rear of the cabinet. Each of these acoustical mounts are insulated, thus preventing vibration in the structural portion of the fuselage from entering the passenger compartment.
