- 2. The lighter of claim 1, wherein the wheel comprises at least two drivers, one located on each side of the wheel.
- 3. The lighter of claim 1, further comprising a cover disposed in an upper portion of the lighter and a cap at least partially surrounding the cover.
- 4. The lighter of claim 3, wherein the axle is supported by the cover.
- 5. The lighter of claim 1, wherein the axle is movable against a biasing force of the spring.
- 6. The lighter of claim 1, wherein the axle is movably supported in a slot.
- 7. The lighter of claim 1, further comprising a cover disposed adjacent the wheel;wherein the axle is movably mounted in rectilinear grooves disposed in the cover, and wherein the axle is movable between a low position in which the wheel is able to rotate without the push button being pressed and unable to rotate when the push button is pressed and a high position in which the wheel is prevented from rotating.
- 8. The lighter of claim 1, wherein the wheel cover comprises a plate having an edge and wherein the edge is adapted to engage the at least one tooth of the at least one driver so as to prevent the rotation of the wheel.
- 9. The lighter of claim 8, wherein the axle is movable between a high position and a low position and wherein the edge is adapted to engage the at least one tooth when the axle is in the high position.
- 10. The lighter of claim 1, wherein the end of the wheel cover that movably engages the wheel comprises a plate having a hole and an edge and wherein the edge is adapted to engage the at least one tooth of the at least one driver so as to prevent the rotation of the wheel.
- 11. A gas lighter having a safety mechanism, the lighter comprising:a lighter body housing a tank of liquefied gas under pressure; a valve allowing passage of gas; a burner connected to the valve; a push-button disposed on the body and adapted to be pressed by a user's finger; a lever for acting on the valve, the lever being adapted to cooperate with the push-button; a wheel for engaging a flint, the wheel comprising at least one driver; a spring arranged below the flint for biasing the flint against the wheel; an axle upon which the wheel is rotatably mounted; and a mechanism for preventing the rotation of the wheel; wherein the mechanism is adapted to engage at least one tooth on the at least one driver so as to prevent the rotation of the wheel, wherein the mechanism for preventing the rotation of the wheel comprises a wheel cover, wherein the wheel cover comprises a plate having an edge and wherein the edge is adapted to engage the at least one tooth of the at least one driver so as to prevent the rotation of the wheel, and wherein the plate of the wheel cover is slidable with respect to an inner surface of a cap surrounding the burner.
- 12. The lighter of claim 11, wherein the wheel cover is one of fixed to the lever and connected to the lever.
- 13. The lighter of claim 11, wherein the wheel cover comprises an end which is fixed to the lever via a connection, the connection being disposed between the wheel and the push-button.
- 14. A gas lighter comprising:a lighter body housing a tank of liquefied gas under pressure; a valve allowing a passage of gas; a burner connected to the valve; a push-button disposed on the body and adapted to be pressed by a user's finger; a lever for acting on the valve, the lever being adapted to cooperate with the push-button; a wheel for engaging a flint, the wheel comprising two drivers; a spring arranged below the flint for biasing the flint against the wheel; an axle mounted to a cover; the axle being movable between a high position and a low position; the wheel being rotatably mounted via the axle; a cap at least partially surrounding the cover; a wheel cover for preventing the rotation of the wheel; the wheel cover having a portion which at least partially surrounds the wheel; the wheel cover comprising an end which is coupled to the push-button and another end which is free; the other end including a plate adapted to slide with respect to an inner surface of the cap; the plate comprising an edge adapted to engage at least one tooth of at least one of the drivers, wherein the wheel is prevented from rotating when the edge engages at least one tooth of at least one driver, and wherein the wheel is rendered rotatable when the axle of the wheel is moved away from the high position towards the low position.
- 15. The lighter of claim 14, wherein the wheel is prevented from rotating when the push-button is in a low position, and wherein the wheel is rendered rotatable when the axle of the wheel is moved away from the high position towards the low position.
- 16. The lighter of claim 14, wherein the wheel is prevented from rotating by the edge engaging at least one tooth of at least one driver when the axle is in the low position and the push-button is in a low position.
- 17. A gas lighter having a safety mechanism, the gas lighter comprising:a lighter body housing a tank of liquefied gas under pressure; a valve allowing a passage of gas; a burner connected to the valve; a push-button disposed on the body and adapted to be pressed by a user's finger; a lever for acting on the valve, the lever being adapted to cooperate with the push-button; a wheel for engaging a flint, the wheel comprising two drivers; a spring arranged below the flint for biasing the flint against the wheel; an axle mounted to a cover; the axle being movable between a high position and a low position; the wheel being rotatably mounted via the axle; a cap at least partially surrounding the cover; a wheel cover for preventing the rotation of the wheel; the wheel cover having a portion which at least partially surrounds the wheel; the wheel cover comprising an end which is coupled to the lever and another end which is free; the free end having an edge adapted to engage at least one tooth of at least one of the drivers, wherein the wheel is prevented from rotating when the axle is in the high position by the edge engaging at least one tooth of at least one driver, and wherein the wheel is rendered rotatable when the axle is moved away from the high position to the low position.
- 18. The lighter of claim 17, wherein the wheel is prevented from rotating by the edge engaging at least one tooth of at least one driver when the axle is in the low position and the push-button is in a low position.
