Abstract

A securing device for a component that can be secured on rails of a floor structure of an aircraft interior includes at least two adapter plates. The adapter plates are decoupled from one another and configured to be secured on the rails. The adapter plates being configured to secure the component having mutually spaced securing attachments.

First claim

The invention claimed is:

1. A securing device configured to secure a single component on rails of a floor structure of an aircraft interior, the securing device comprising:
at least two adapter plates, which are decoupled from one another and configured to be secured on the rails, and configured to collectively secure the same component having mutually spaced securing attachments;
ball-and-socket joints, in each connection, configured to be between the component and the rails, each of the ball-and-socket joints comprising a dimensionally stable ball and a dimensionally stable ball socket, and the dimensionally stable ball socket of each of the ball-and-socket joints having two dimensionally stable ball socket halves,
wherein each of the adapter plates is configured to be secured to two different rails of the rails,
wherein each of the adapter plates is configured to be held in place on the rails at three mounting points such that each of the adapter plates is configured to be mounted on one of the rails at a first mounting point and on another rail at two second mounting points,
wherein each of the adapter plates is configured to be mounted on the rails so as to be slidable at the first mounting point,
wherein the dimensionally stable ball of each of the ball-and-socket joints is configured to be associated with at least one of the rails, and
wherein the dimensionally stable ball socket of each of the ball-and-socket joints is associated with at least one of the adapter plates,
wherein the two dimensionally stable ball socket halves of each of the ball-and-socket joints are formed by a respective first support plate and second support plate,
wherein, in an assembled position, the two dimensionally stable ball socket halves complement each other to form the dimensionally stable ball socket, each ball socket comprising a ball bore extending there-through in the vertical direction such that the ball is accepted therein, each ball of the ball and socket joint accepted into the ball bore has a fastener opening passing therethrough such that a fastener is fastened through the ball and into a receiving member, the receiving member being configured to be fastened within a respective rail such that the adapter plates are configured to be mounted on the rail through the ball and socket joint,
wherein, for each of the ball-and-socket joints:
the first support plate and the second support plate in the assembled position are each connected by a tongue and groove joint to an adapter plate of the adapter plates, and
the tongue and groove joint is configured to be oriented transversely to the rails to which the adapter plate is configured to be secured, and
wherein faces of the first support plate and the second support plate, in the assembled position, are configured to abut vertically one on top of the other along two completely linear surfaces within a horizontal plane for the entire interface of the first and second support plates.

2. A securing system, the securing system comprising:
the securing device according to claim 1 ; and
a second securing device comprising at least two second adapter plates, which are configured to secure a second component to the rails,
wherein:
a side face of each of the adapter plates of the securing device is contoured such that it is configured to engage with a complementary side face of each of the corresponding second adapter plates of the second securing device;
in a condition where the adapter plates and the second adapter plates are arranged on a common rail, of the rails, and
in a condition where the side face and the complementary side face of pairs of the adapter plates and second adapter plates are arranged directly adjacent to one another on the common rail.

3. The securing system according to claim 2 , wherein:
the side face of each of the adapter plates for securing the component has a negative contour configured to be complementary to a positive contour of the complementary side face of each of the corresponding second adapter plates for securing the second component in order for the side face and complementary side face of each of the pairs of the adapter plates and the second adapter plates to mutually engage with each other.

4. A securing system, the securing system comprising:
the securing device according to claim 1 ; and
a second securing device comprising at least two second adapter plates, which are configured to secure a second component to the rails, wherein:
each of the adapter plates and the second adapter plates are configured to be secured to two different rails of the rails,
each of the adapter plates and the second adapter plates are configured to be mounted on a first one of the rails at a respective first mounting point and on a second of the rails at two respective second mounting points,
the two respective second mounting points of each of the adapter plates and the second adapter plates are arranged on respective finger-shaped spaced apart projections, and
the respective first mounting point of each of the adapter plates and the second adapter plates are configured to be arranged on a respective individual finger-shaped projection, and
the respective first mounting point of each of the second adapter plates being configured to be supported on the first rail on the respective individual finger-shaped projection, which is arranged between the respective finger-shaped spaced apart projections of the two second mounting points of a respective one of the adapter plates.

5. The securing device according to claim 1 , wherein
a tongue of the tongue and groove joint is arranged on the adapter plate,
a groove of the tongue and groove joint has two shoulders that complement each other in the assembled position to form the groove, and
each of the two shoulders being arranged on one of the first support plate or the second support plate.

6. The securing device according to claim 1 , wherein the first support plate and the second support plate are supported on the adapter plate by two tongue and groove joints that are arranged on opposite lateral sides of the first support plate and the second support plate.

7. The securing device according to claim 6 , wherein the opposite lateral sides extend in parallel with one another.

8. The securing device according to claim 1 , wherein the ball-and-socket joints are configured to be in each connection between the adapter plates and the rails.

9. The securing device according to claim 1 , wherein the tongue and groove joint is configured to be oriented perpendicularly to the rails to which the adapter plate is configured to be secured.

10. The securing device according to claim 1 , wherein, for each of the ball and socket joints, in the assembled stated, the first support plate and second support plate circumferentially surround a lateral portion of the ball, with a portion of the ball extending beyond an opening in an outer face of the second support plate.

11. The securing device according to claim 1 , wherein for each of the ball and socket joints, the first support plate has an inner facing surface that is shaped to form one of the ball socket halves and the second support plate has an inner facing surface that is shaped to form another one of the ball socket halves.

12. The securing device according to claim 1 , wherein for each of the ball and socket joints, the ball socket halves are respectively shaped such that the widths thereof only begin to decrease into the first support plate and the second support plate from opening cross sections that face one another in the assembled state such that the ball is insertable into either of the ball socket halves pr
