Floor plate for covering a floor framework in an aircraft
The invention relates to a floor plate for bearing upon a floor framework in an aircraft. The floor framework is formed with a multiplicity of transverse beams which are arranged like a truss, and a multiplicity of longitudinal profiles, especially seat rail profiles, which extend transversely to the transverse beam. At least one sub-assembly, for example a kitchen module and/or a sanitary cell, can be fastened on the floor plate. The floor plate bears upon at least four longitudinal profiles and has at least one connecting point, especially an insert, for fastening of the sub-assembly. In addition, at least one system port is provided for the tool-less, pluggable connecting of the sub-assembly to any on-board systems of the aircraft, especially to electrical systems, to feed-air systems, to exhaust air systems, to fresh-water systems or to waste-water systems.
1. A floor plate for covering a floor framework in an aircraft, wherein the floor framework comprises a plurality of transverse beams and with a plurality of longitudinal profiles extending at an angle of about 90° plurality of to the transverse beams,
the floor plate comprising:
at least one connecting point for fastening a sub-assembly to the floor plate independently of an installation point of the floor plate to the floor framework,
a system port arranged in a center region of the floor plate for connecting the sub-assembly on the floor plate to a plurality of systems on board the aircraft comprising sockets and couplings,
wherein the system port is integrated directly into the floor plate, and is configured to form a universal interfacing point between the sub-assembly and the plurality of systems on board the aircraft, and
at least one of a plug and a coupling integrated into an underside of the sub-assembly capable of automatically making connections or contacts to the sockets and couplings of the system port,
wherein the floor plate is configured to bear on the floor framework of the aircraft on at least four longitudinal profiles, and
wherein the sub-assembly is directly fastenable to the floor plate, and the floor plate is connectable to the floor framework with fastening devices.
2. The floor plate according to claim 1 , wherein the sub-assembly fastened on the floor plate is connected to an on-board system of the aircraft by the system port without the use of tools.
3. The floor plate according to claim 1 , wherein the floor plate is provided with at least one structural reinforcement element, and wherein the at least one structural reinforcement element is an integral part of the floor plate.
4. The floor plate according to claim 3 , wherein the at least one structural reinforcement element is at least one thickened portion.
5. The floor plate according to claim 4 , wherein the at least one thickened portion has a width which corresponds to a seat rail distance between the plurality of longitudinal profiles.
6. The floor plate according to claim 1 , wherein the floor plate is formed as a sandwich plate.
7. The floor plate according to claim 1 , wherein the plurality of longitudinal profiles are formed as seat rail profiles.
8. The floor plate according to claim 1 , wherein the floor plate is connected to the plurality of longitudinal profiles.
9. The floor plate according to claim 1 , wherein the floor plate is connected to the floor framework with at least one of a plurality of screws and rivets.
10. The floor plate according to claim 1 , wherein the floor plate is sized to be fastened on the floor framework in a manner that is positionaly variable.
11. The floor plate according to claim 1 , wherein a surface of the floor plate is equal to or larger than a base area of the sub-assembly.
