Tubeless bicycle wheel bead lock

1. A vehicle wheel comprising:

a wheel rim having a first sidewall and a second sidewall defining a rim trough and an opening extending through a portion of the wheel rim;

a tire having a tire bead positioned in the rim trough in engagement with the first sidewall; and

a bead lock positioned in the rim trough adjacent the tire bead,

wherein the bead lock is movable between a locked position in which the bead lock substantially inhibits movement of the tire bead away from the first sidewall and an unlocked position in which the bead lock permits movement of the tire bead away from the first sidewall,

wherein the bead lock includes an actuator positioned in the opening and including a portion accessible from outside the wheel rim,

wherein the bead lock further includes a band positioned in the rim trough and including two free ends movable relative to each other, the band including a side edge engaged with the tire bead, and

wherein the side edge includes a cut out that creates a recessed edge that is not engaged with the tire bead.

2. A vehicle wheel as claimed in claim 1 , wherein the bead lock further comprises a tightening mechanism secured to the two free ends.

3. A vehicle wheel as claimed in claim 2 , wherein the tightening mechanism includes a winch and a cable wrapped around the winch and secured to one of the free ends.

4. A vehicle wheel as claimed in claim 3 , wherein the winch is coupled for rotation with the actuator.

5. A vehicle wheel as claimed in claim 1 , wherein the actuator is mounted for rotation relative to the wheel rim, and wherein the vehicle wheel further includes a seal between the actuator and the wheel rim to inhibit a passage of gas between the actuator and the wheel rim.

6. A vehicle wheel as claimed in claim 1 , wherein the actuator comprises:

a tubular member having a hollow interior; and

a valve mechanism positioned in the hollow interior to control a passage of gas into and out of an interior volume defined by the tire and the wheel rim.

7. A vehicle wheel adapted to receive a tire having a tire bead, the vehicle wheel comprising:

a wheel rim having a first sidewall and a second sidewall defining a rim trough and an opening extending through a portion of the wheel rim; and

a bead lock positioned in the rim trough adjacent the tire bead,

wherein the bead lock is movable between a locked position and an unlocked position,

wherein the bead lock includes an actuator capable of moving the bead lock from the unlocked position to the locked position,

wherein the actuator is at least partially positioned in the opening and includes a portion accessible from outside the wheel rim,

wherein the bead lock further includes a band positioned in the rim trough and including two free ends movable relative to each other, the band including a side edge engaged with the tire bead, and

wherein the side edge includes a cut out that creates a recessed edge that is not engaged with the tire bead.

8. A vehicle wheel as claimed in claim 7 , wherein the bead lock further comprises a tightening mechanism secured to the two free ends.

9. A vehicle wheel as claimed in claim 8 , wherein the tightening mechanism includes a winch and a cable wrapped around the winch and secured to one of the free ends.

10. A vehicle wheel as claimed in claim 9 , wherein the winch is coupled for rotation with the actuator.

11. A vehicle wheel as claimed in claim 7 , wherein the actuator is mounted for rotation relative to the rim, and wherein the vehicle wheel further includes a seal between the actuator and the wheel rim to inhibit a passage of gas between the actuator and the wheel rim.

12. A vehicle wheel as claimed in claim 7 , wherein the actuator comprises:

a tubular member having a hollow interior; and

a valve mechanism positioned in the hollow interior to control a passage of gas through the tubular member.
