Connection mechanism and method

1 . A connection mechanism for connecting first and second parts to one another comprising:

a first part to be connected having a first connection member, said first connection member having a connection surface and a connection rib extending outwardly therefrom;

a second part to be connected having a second connection member, said second connection member having a connection surface generally parallel to the connection surface of said first connection member and a connection groove formed therein to receive said connection rib;

a backing member extending outwardly from the surface portion of one of the first and second members to retain the first and second connection members in connecting engagement with said connection rib received within said connection groove; and

at least one of said first and second connection members and said backing member being sufficiently flexible to permit said connection rib to be inserted into and received by said connection groove.

2 . The connection mechanism of claim 1 in combination with a further connection mechanism.

3 . The connection mechanism of claim 2 wherein said further connection mechanism is one or more of friction stir welding, brazing and bonding.

4 . The connection mechanism of claim 2 wherein said further connection mechanism is friction stir welding.

5 . The connection mechanism of claim 2 wherein said further connection mechanism is bonding.

6 . A connection mechanism for connecting first and second parts together comprising the combination of:

a self-locking connection mechanism and

a further connection mechanism comprising one or more of friction stir welding, brazing, conventional welding and bonding.

7 . The connection mechanism of claim 6 wherein said self-locking connection member includes a first connection member and a second connection member, one of said first and second connection members including a connection rib and the other of said first and second connection members including a connection groove to receive said connection rib.

8 . The connection mechanism of claim 7 wherein said further connection mechanism is friction stir welding.

9 . The connection mechanism of claim 8 wherein said one first and second connection members includes a connection rib on each side thereof and said other first and second connection members includes a connection groove on each side thereof.

10 . The connection mechanism of claim 9 wherein said first connection member includes a connection rib on each side thereof and said second connection member includes a connection groove on each side thereof.

11 . A method of connecting first and second parts together comprising:

providing a first part with a first self-locking connection member;

providing a second part with a second self-locking connection member, said first and second self-locking connection members being selectively connectable to one another via a self-locking connection;

connecting said first and second parts via said self-locking connection to provide a connection site; and

applying a further connection mechanism to said connection site.

12 . The method of claim 11 wherein said further connection mechanism is one of friction stir welding, brazing, conventional welding and bonding.

13 . The method of claim 12 wherein said further connection mechanism is friction stir welding.

14 . The method of claim 11 wherein said connection site is a seam between first and second edges of said first and second members.

15 . The method of claim 14 wherein said further connection mechanism is friction stir welding applied along said seam.

16 . The method of claim 11 wherein said further connection mechanism is friction stir welding applied through a portion of one of said first and second members and into a portion of the other of said first and second members.

17 . A method of connecting first and second parts together comprising:

providing a first member with a first self-locking connection member;

providing a second member with a second self-locking connection member;

providing a bridging member with first and second complementary self-locking connection members, said first and second complementary connection members being selectively connectable to said first and second connection members via a self-locking connection;

connecting said first and second pars together via said bridging member and said self-locking connection to provide a connection site between said first and second members; and

applying a further connection mechanism in the form of a friction welding to said connection site.

18 . The method of claim 17 wherein said further connection mechanism is one or more of friction stir welding, brazing, conventional welding and bonding.

19 . The method of claim 18 wherein said further connection mechanism is friction stir welding.

20 . An aircraft wing comprising:

a base member having a plurality of spaced struts, each of said struts including an edge with a first connection member along said edge;

a cover member having a plurality of second connection members spaced along an inner surface thereof to correspond to the first connection members of said struts, said first and second connection members being selectively connectable to one another via a self-locking connection; and

said base member and said cover member connected to one another via said self-locking connection.

21 . The method of claim 20 wherein said base member and said cover member are further connected to one another by a further connection mechanism comprising one or more of friction stir welding, brazing, conventional welding and bonding applied in the area of engagement between said first and second connection members.

22 . The method of claim 21 wherein said further connection mechanism is friction stir welding.

23 . A method of making an aircraft wing comprising:

providing a base with a plurality of struts, at least one of said struts including a first connection member along an edge thereof;

providing a cover with a second connection member corresponding to said first connection member, said first and second connection members being selectively connectable to one another via a self-locking connection;

connecting said base and cover via self-locking connection; and

applying a further connection mechanism between said cover and said base in the area of said self-locking connection by one or more of friction stir welding, brazing, conventional welding and bonding.
