Abstract

A floor system for creating a floor in an interior of a vehicle has base part and a floor panel. The base part having a trough-shaped depression and the floor panel are attached to a floor support structure and together provide a customary installation height and also cavities for accommodating installation objects.

First claim

The invention claimed is:

1. A floor system for creating a floor in an interior of a vehicle, comprising:
a base part for laying on a floor support structure of the vehicle, the floor support structure comprising at least a first floor support with a first lateral surface and a second floor support with a second lateral surface; and
a floor panel configured to be laid on the base part,
wherein the base part has at least two peripheral surfaces and apposed bearing surfaces and a trough-shaped depression arranged therebetween for receiving installation objects, the bearing surfaces for laying on the lateral surfaces of the first and second supports,
wherein the base part has at least one stiffening member arranged in the depression, the stiffening member extending over the entire height of the depression, wherein the floor panel and the at least one stiffening member have first connection members and second connection members arranged in a complementary manner to one another, which are configured for detachable, form-fitting connection of the floor panel and the at least one stiffening member,
wherein at least one first connection member is arranged on the at least one stiffening member and at least one second connection member is arranged on an underside of the floor panel, and
wherein the floor panel is configured to correspond to the base part, so that the floor panel is placed on the peripheral surfaces and the at least one reinforcing component and the at least one second connection member forms a connection with the at least one first connection member.

2. The floor system according to claim 1 , wherein the first connection members and the second connection members are configured to produce a snap-on connection.

3. The floor system according to claim 1 , wherein each of the connection members extends along a straight section on the at least one stiffening member and the floor panel.

4. The floor system according to claim 1 , wherein each of the connection members extends along at least 90% of an available length of the at least one stiffening member or the floor panel.

5. The floor system according to claim 1 , wherein one of the first connection members and the second connection members has a first profile cross section and the other of the first connection members and the second connection members has a second profile cross section,
wherein the first profile cross section includes a bulge,
wherein the second profile cross section includes an indentation, and
wherein the first profile cross section and the second profile cross section are configured so that the bulge snaps into the indentation upon application of pressure.

6. The floor system according to claim 5 , wherein the bulge is based on an arcuate form or a drop shape.

7. The floor system according to claim 1 , wherein the second connection element is adhered to an underside of the floor panel.

8. The floor system according to claim 1 , wherein at least one of the first connection members and second connection members is made of a metallic material.

9. The floor system according to claim 1 , wherein the base part is made of a fibre-reinforced plastic material.

10. The floor system according to claim 1 , wherein the floor panel is made of a fibre-reinforced plastic material.

11. The floor system according to claim 1 , wherein the second connection element is integrated in a top layer of the floor panel.

12. The floor system according to claim 1 , wherein multiple stiffening members are uniformly distributed in the depression.

13. An aircraft comprising an interior with a floor support structure and a floor arranged thereupon, wherein the floor is produced using a floor system according to claim 1 .

14. The aircraft according to claim 13 , wherein the interior is a cabin or a cargo hold.

15. The floor system according to claim 1 , wherein the base part comprises at least one first hole in at least one of the peripheral surfaces,
wherein the floor panel comprises at least one second hole aligned with the at least one first hole to receive a fastener.
