Definitions

• a gas lighter comprising a safety ignition system.
• a gas lighter generally comprises a tank intended to contain a liquefied petroleum gas, a valve mounted on the tank allowing the gas to leave the tank, a system for opening and closing the flow of gas controlled by a lever, a system regulating the gas flow and an ignition system.
• the latter comprises a stone cooperating with a wheel and, most often, a protective cover.
• the wheel is mounted on an axis between two coaches.
• the wheel is cylindrical in shape and the coaches have the shape of a disc with a diameter substantially greater than that of the wheel.
• the edge of the coaches has roughness making it rough. Thus, a user can easily drive the wheel with a finger, because the finger does not slide on the coaches.
• Another object of the invention is to provide a reliable security system, inviolable and constantly in action, without prior intervention.
• Another objective is to have an operation of the lighter as close as possible to the operation of a lighter of the aforementioned type, so that the user does not need either instructions or prior learning to use it. lighter.
• the invention provides a gas lighter of the type comprising a reservoir intended to contain a liquefied petroleum gas, a valve mounted on the reservoir and allowing the gas to exit the reservoir, an opening and closing system for the gas flow, as well as an ignition system having a stone cooperating with a wheel driven in rotation by at least one driver mounted coaxially with the wheel.
• the peripheral surface of each coach intended to come into contact with a finger of a user is smooth.
• a user to drive the wheel through the trainer, a user must exert on it a force comprising a large radial component and he must accompany this trainer in its rotational movement to generate sparks.
• the movement made by the user to use the lighter is then the same as that which he makes to use a lighter of the prior art, but it must better accompany the movement of the trainer by exerting a force. , essentially radial, larger. Therefore, a child can hardly use such a lighter.
• the wheel is a wheel of cylindrical shape mounted on an axis between two coaches in the general shape of a disc of diameter substantially greater than the diameter of the wheel. This configuration allows good training of the wheel by the coaches.
• each coach is a circular disc.
• each driver is in the general shape of a disc, the peripheral surface of which has undulations. This profile of coaches promotes their actuation, without however allowing their operation by a young child.
• FIG. 1 is a perspective view of a lighter according to the invention.
• Figure 2 is a side view, partially in section and on an enlarged scale, of the lighter of Figure 1.
• the tank On its upper part, the tank is provided with a valve 2 allowing the gas to escape when the valve 2 is in the open position.
• a lever 3 controls the opening and closing of the valve 2.
• a spring 4 acts on the lever 3, so that in the rest position, the valve 2 is closed.
• the part of the lever 3 located opposite the valve 2 is actuated by a user, when the latter wishes gas to escape from the reservoir, to supply a flame for example.
• the lighter also includes an ignition system for igniting the gas leaving through the valve 2.
• This system includes a lighter stone 5 and a thumb wheel 6. The latter is mounted on an axis 7 and can rotate around it. . It is cylindrical in shape and its peripheral surface is knurled.
• the lighter stone 5 bears radially on the wheel 6.
• a spring 8 keeps it in support.
• sparks are produced. These can ignite gas escaping through the valve 2.
• two coaches 9 are mounted on either side of the wheel 6. These coaches 9 may form a single piece with the wheel 6, or they may be separate parts made integral with wheel 6.
• These coaches 9 are circular discs, the peripheral surface of which forms the edge is smooth. Thus, the coefficient of friction between the finger of a user and these coaches 9 is relatively low.
• the user places a finger 10 on the coaches 9, on the side opposite to the stone 5. He presses on these coaches 9 with a force having a high radial component.
• the finger 10 In order to continue the rotational drive, the finger 10 must continue to exert a force having a high radial component and at the same time follow the movement of the coaches 9. The finger 10 continues its race until it comes into contact with the lever 3. Compared to a lighter of the prior art with rough coaches, the user's finger must accompany the rotation of the wheel on a relatively high angle of rotation. The wheel grip is deliberately accentuated in terms of angle of rotation.
• the surface of P (or the) trainer (s) is smooth, but it is not necessarily circular. Ripples could be expected on the side of the coaches.
