Bicycle carriers and skewer assemblies

1. An assembly for securing a bicycle having first and second fork prongs to a vehicle, the assembly comprising:

an elongated skewer for mounting the first and second fork prongs of the bicycle thereon and having an end portion;

a lever rotatably coupled to the end portion of the elongated skewer and having a cam portion;

a cam follower movably coupled to the elongated skewer, wherein the cam follower engages the cam portion of the lever such that the cam follower moves along the elongated skewer as the lever rotates; and

a lock assembly, separate from the lever and the cam follower, that locks the lever at a closed position, wherein the lock assembly is coupled to the end portion of the elongated skewer such that the lock assembly is disposed around the end portion of the elongated skewer.

2. The assembly of claim 1 , wherein the elongated skewer is non-threaded.

3. The assembly of claim 1 , wherein the lock assembly comprises a fixed member directly coupled to the end portion of the elongated skewer.

4. The assembly of claim 3 , wherein the fixed member comprises a pivot pin extending transversely through the fixed member and the end portion of the elongated skewer, and wherein the pivot pin is coupled to the lever.

5. The assembly of claim 1 , wherein the lock assembly comprises a lock housing and a lock cylinder disposed within the lock housing.

6. The assembly of claim 1 , wherein the lock assembly comprises one or more extending members that extend away from the end portion of the elongated skewer.

7. The assembly of claim 6 , wherein the one or more extending members extend in a direction perpendicular to a longitudinal axis of the elongated skewer.

8. The assembly of claim 3 , wherein the lock assembly comprises an extending member having a first end coupled to the fixed member.

9. The assembly of claim 8 , wherein the lock assembly comprises a lock cylinder coupled to a second end of the extending member, and wherein the lock cylinder is spaced from the end portion of the elongated skewer.

10. The assembly of claim 5 , wherein the lever comprises an opening configured to receive the lock housing when the lever is at the closed position.

11. The assembly of claim 10 , wherein the lever comprises a circular opening, wherein the circular opening is aligned with the lock cylinder when the lever is at the closed position.

12. An assembly for securing a bicycle having first and second fork prongs to a vehicle, the assembly comprising:

an elongated skewer for mounting the first and second fork prongs of the bicycle thereon and having an end portion;

a lever rotatably coupled to the end portion of the elongated skewer and having a cam portion;

a cam follower movably coupled to the elongated skewer, wherein the cam follower engages the cam portion of the lever and moves along the elongated skewer as the lever rotates; and

a lock assembly, separate from the lever and the cam follower, that locks the lever at a closed position, wherein the lock assembly comprises:

a fixed member directly coupled to the end portion of the elongated skewer,

an extending member having a first end coupled to the fixed member, and

a lock cylinder coupled to a second end of the extending member, wherein the lock cylinder is spaced from the end portion of the elongated skewer.

13. The assembly of claim 12 , wherein the extending member extends in a direction perpendicular to a longitudinal axis of the elongated skewer.

14. The assembly of claim 12 , wherein the lever has a center of mass aligned with an axis of rotation and a longitudinal axis of the elongated skewer when the lever is at an open position.

15. The assembly of claim 12 , wherein the lock assembly comprises a movable lock cam that rotates to engage a surface of the lever to lock the lever at the closed position.

16. The assembly of claim 15 , wherein the lock assembly comprises a lock housing, and wherein the movable lock cam is rotatably coupled to the lock housing.

17. The assembly of claim 16 , wherein the movable lock cam extends radially beyond a periphery of the lock housing and is configured to engage a surface of the lever to lock the lever at the closed position.

18. A system for securing a bicycle having first and second fork prongs to a vehicle roof, the system comprising:

a carrier mounted to the vehicle roof, the roof having a proximal edge and a distal edge;

a skewer coupled to the carrier configured to receive the first and second fork prongs of the bicycle thereon, the skewer having a first end portion disposed toward the proximal edge of the roof and a second end portion disposed toward the distal edge of the roof;

an adjustment assembly coupled to the first end portion of the skewer, wherein the adjustment assembly comprises:

a lever rotatably coupled to the first end portion of the skewer and having a cam portion,

a cam follower movably coupled to the skewer, wherein the cam follower engages the cam portion of the lever and moves along the skewer as the lever rotates, and

a lock assembly, separate from the lever and the cam follower, that locks the lever at a closed position, wherein the lock assembly is coupled to the first end portion of the skewer and disposed around the first end portion of the skewer.

19. The system of claim 18 , wherein the lever has a center of mass aligned with an axis of rotation and a longitudinal axis of the skewer when the lever is at an open position such that the adjustment assembly and lock assembly remain in a fixed position.

20. The system of claim 18 , wherein the skewer is non-threaded.
