Abstract

The invention relates to a gas-fired cigarette lighter comprising a gas reservoir, a gas distributor valve and means which make it possible to ignite the gas emerging from this distributor valve, comprising at least one reserve supply of gas and means for draining this reserve supply into the gas reservoir. This lighter is remarkable in that it is rechargeable and comprises a filling device enabling simultaneous filling of the reserve supply and of the gas reservoir, the filling device comprising two serially disposed valves, opening of the valve situated between the reserve supply of gas and the other valve being operated either by the opening of this other valve or by an operating element, this other valve then remaining closed.

Claims

1. A gas-fired cigarette lighter comprising a gas reservoir, a gas distributor valve and means which make it possible to ignite the gas emerging from this distributor valve, at least one reserve supply of gas and means for draining this reserve supply into the gas reservoir, a filling device enabling simultaneous filling of the reserve supply and of the gas reservoir, the filing device comprising two serially disposed valves one of which is situated between the reserve supply of gas and the gas reservoir and the other of which is situated between the gas reservoir and the outside of the lighter, means for simultaneously opening both said valves during filling, and means for opening only said one valve during transfer of gas from said reserve supply to said reservoir.

2. A cigarette lighter according to claim 1, characterised in that the reserve supply and the two valves are mounted in a casing and in that the interior of this casing is linked, between the two valves, to the main reservoir.

3. A cigarette lighter according to claim 2, characterised in that a pivoting plate occludes access to the filling device in the position of normal operation.

4. A cigarette lighter according to claim 3, characterised in that an angular displacement of 180°

of this plate and a subsequent displacement thereof axially towards the body produce operation of the element which controls the valve situated between the reserve supply and the other valve.

5. A cigarette lighter according to claim 4, said means to ignite the gas comprising a flint, characterised in that in the position of normal operation the plate occludes a cavity adapted to receive a spare flint.

6. A cigarette lighter according to claim 1, characterised in that the reserve supply of gas is situated inside the gas reservoir.

7. A cigarette lighter according to claim 1, characterised in that it comprises a roller operating means which make it possible to ignite the gas and in that the reserve supply of gas is at least partially housed inside this roller.

8. A cigarette lighter according to claim 1, characterised in that the reserve supply of gas is coaxial with the filling device.

9. A cigarette lighter according to claim 7, characterised in that it comprises a cover articulated on the body, and in that the housing of the roller is situated below the edge of the cover which bears on the body and in that the body is of monobloc construction.

10. A cigarette lighter according to claim 9, characterised in that it comprises an operating connection linking the cover with the distributor valve in such a way that this valve is opened only during the course of the final part of the angular travel performed by the cover as it opens.

11. A cigarette lighter according to claim 10, said means to ignite the gas comprising a flint, characterised in that it comprises an abutment maintaining the cover partially open during installation of a flint, so that the distributor valve is in the closed position during this partially open position of the cover.

12. A cigarette lighter according to claim 7, characterised in that the roller is pivoted at its bottom end on the casing containing the reserve supply of gas and in that its top end is rigid with a spindle pivoted on the body of the cigarette lighter, the other end of which operates means which make it possible to ignite the gas.

13. A cigarette lighter according to claim 12, characterised in that it comprises a device for regulating the height of the flame, the control element of which is pivoted coaxially with this spindle.

14. A cigarette lighter according to claim 12, characterised in that the spindle rigid with the roller carries at its free end a wheel co-operating with a flint housed in a flint carrier.

15. A cigarette lighter according to claim 14, characterised in that the flint carrier is articulated in respect of the body according to a direction at right-angles to that according to which the cover is articulated on this body.

16. A cigarette lighter according to claim 15, characterised in that the flint carrier, when it is in the position needed for fitment of a flint, constitutes an abutment which maintains the cover in the partially open position.
