Abstract

A coupling kit-of-parts is provided for mounting an interior substructure to a primary structure of an aircraft. The kit includes a locking member and a mounting member. When the locking member is inserted into the mounting member, a first member part and a second member part are pushed radially outward to engage the primary structure in a form-fitting manner. When the locking member is removed, the first and second member parts are urged radially inward thereby disengaging from the primary structure.

First claim

The invention claimed is:

1. A coupling kit-of-parts for a mounting arrangement that is configured for mounting an interior substructure to a primary structure of an aircraft, the kit-of-parts comprising:
a locking member; and
a mounting member including a first member part and a second member part that are movably supported by a common support member,
wherein the first and second member parts form a locking channel therebetween that is configured to receive the locking member,
wherein the mounting member is configured such that, when the locking member is inserted into the locking channel, the first and second member parts are pushed radially outward by the locking member.

2. The kit-of-parts according to claim 1 further comprising an elastic member that is configured to urge the first and second member parts radially inward along a radial direction such that, when the locking member is removed from the locking channel, the first and second member parts are pushed radially inward by the elastic member.

3. The kit-of-parts according to claim 1 , wherein the support member includes a guiding recess that is configured to guide the first and second member parts along a radial direction.

4. The kit-of-parts according to claim 1 , wherein at least one of the first member part or the second member part include a head portion that engages the support member in a sliding manner.

5. The kit-of parts according to claim 4 , wherein the head portion engages the guiding recess of the support member in a sliding manner.

6. The kit-of-parts according to claim 1 , wherein at least one of the first member part or the second member part include an engagement surface that is configured to engage a structure interface bushing in a form-fitting manner.

7. The kit-of-parts according to claim 1 ,
wherein the locking channel comprises a tapered channel entrance portion and a channel portion that matches the locking member,
wherein, when the locking member is inserted past the channel entrance portion, the first and second member parts are radially moved apart, and the channel portion is supported on the locking member.

8. The kit-of-parts according to claim 1 , wherein at least one of the first member part or the second member part include a mounting member end portion that comprises an outward facing tapered surface.

9. The kit-of-parts according to claim 1 , further comprising a retaining bushing that is inserted in the support member and retains the locking member in a manner that requires overcoming a mechanical resistance, when removing the locking member from the support member.

10. The kit-of-parts according to claim 1 , further comprising a structure interface bushing that is configured to get engaged by the radially pushed first and second member parts, when the locking member is inserted in the locking channel, such that the mounting member is affixed to the structure interface bushing.

11. A mounting arrangement for mounting an interior substructure to a primary structure of an aircraft, the arrangement comprising:
a primary structure portion;
an interior substructure member having a substructure mounting opening configured to mount the interior substructure to the primary structure portion;
a coupling kit-of-parts according to claim 10 ,
wherein the structure interface bushing is affixed to the primary structure portion, wherein the mounting member is inserted in the mounting opening such that the support member is arranged in a manner that prevents the interior substructure from being removed from the mounting member.

12. The mounting arrangement according to claim 11 , wherein an elastic member is arranged between the structure interface bushing and the support member.

13. The mounting arrangement according to claim 11 , wherein at least one of the first member part or the second member part include an engagement surface that engages the structure interface bushing in a form-fitting manner, when the locking member is inserted in the locking channel.

14. The mounting arrangement according to claim 11 , wherein at least one of the first member part or the second member part include a shank portion that is at least partially inserted in the structure interface bushing.

15. An aircraft cabin or a cargo hold comprising an interior component, an interior substructure, and a mounting arrangement according to claim 11 ,
wherein the interior substructure member is part of the interior substructure, and
wherein the interior component is mounted to the interior substructure and the interior substructure is mounted to the primary structure portion by the mounting arrangement.

16. An aircraft comprising an aircraft cabin according to claim 15 .
