Definitions

  • the present invention relates to a safety lighter, with delayed gas opening, of the type comprising, fitted in its body, a normally gaseous fuel tank, stored in the liquid phase, a pressure reducer-evaporator located between the tank and a burner- gas outlet shut-off valve controlled by a lever articulated on an axis orthogonal to that of the valve burner, one end or anterior end of which, normally applied against a shoulder of the valve burner, constantly tends to hold the valve in position closing, against the pressure exerted on it by the gas and whose other end, or rear actuating end, is constantly subjected to the action of a spring means which tends to rotate it in the direction corresponding to the closing of the valve.
  • the lighting of such a lighter consists in acting on the rear end of the lever, against the aforementioned spring means, to release the valve for its opening under the action of the gas under pressure and to actuate, roughly simultaneously, a mechanism for producing an ignition spark.
  • the opening of the valve only occur at the end of the operation of the lever, not only fear that the release of the gas does not take place until the moment of production of the spark above the burner, in the event that the latter is prior to the start of operation of the lever, which promotes ignition, but also, so that the opening time of the valve is reduced as much as possible.
  • a lighter is tightened in a pocket of clothing or bag, it is possible that one of the constraints to which it is subjected tends to tilt the lever in the direction of opening of the valve and, in the absence of neutral travel, such a tilting inevitably leads to an unnecessary loss of gas.
  • valve is only opened at the end of its control lever travel, when the lighter is a child-resistant lighter, that is to say comprising a blocking mechanism. of the control lever in the valve closed position, which can be operated in the retracted position to allow the ignition of the flame but, normally, automatically returned to the active blocking position after each operation of the control lever.
  • This mechanism includes retractable stops normally located on the path of part of the rear end of the control lever. For this mechanism to play its role perfectly, it is necessary that it oppose any pivoting of the lever, even over a very small angular travel, since, as soon as it is released by the control lever, the valve is pushed back into position d opening by pressurized gas released by the pressure reducer-evaporator.
  • the manufacturing tolerances make it possible to eliminate any play between the control lever and the retractable stops of its blocking mechanism but, moreover, the progressive deformation of the lever, in particular because of the heat generated by the flame tends to increase this game at the expense of safety.
  • the first elastic means keeps the second in the activated position to the maximum, as compressed and the sum of the two reactions of the elastic means is opposed when the valve opens. It is only during the operation of the control lever, in the direction of opening of the valve, that the second elastic means alone continues, initially, to oppose the opening of the valve and it is only by maneuvering the control lever even more that the deactivation of the second elastic means frees the valve sufficiently to authorize its opening.
  • this second elastic means differs the opening of the valve by a time corresponding to a predetermined fraction of the angular travel, or neutral travel, in the direction of opening of the valve, of the lever. control of its opening / closing.
  • the second elastic means consists of the control lever shaped so as to have an elastically deformable section, between its front end of support on the valve burner and its end. posterior actuation and this is achieved by the fact that the anterior end of the control lever which totally or partially surrounds the upper end of the valve burner is divided, by a V-shaped slot, into two superimposed segments, linked to the to each other by a veil of elastic material, acting as an elastic hinge, and the lower one of which is normally inclined downward but can be brought elastically closer to the upper segment under the action of a force less than that generated by the first elastic means but greater than that generated by the pressure of the gas under the valve.
  • the present invention aims to overcome this drawback.
  • the control lever is composed of two consecutive segments linked to each other by a bridge of elastically flexible material, acting as an elastic hinge and constituting the second elastic means, with stop for limiting the bending of this bridge, when the control lever is in the holding position in the closed position of the valve burner.
  • the bridge of elastically flexible material connects the lower parts of the two segments of the control lever and their corresponding upper parts, normally separated from one another, forming the edges of the vertical slot, constitute the stops limiting the bending. up the front lever segment.
  • the front end 5a of the lever 5, that is to say that located on the left in the drawing, is shaped in a crown so as to surround the upper end 4b of the valve burner 4, while its other end, or rear actuating end 5b is constantly subjected to the action of a helical spring 8 compressed between it and the upper part of the body 2 of the lighter.
  • This spring 8 which constitutes the first elastic means of this lighter, constantly tends to rotate the lever 5 in the direction of the arrow 9, that is to say in the direction in which its front end 5a holds the burner- valve 4 in the closed position by pressing against a shoulder 4c of this valve burner 4.
  • the ignition mechanism of this lighter has not been shown, that is to say the mechanism responsible for producing a gas ignition spark after opening the valve burner.
  • This ignition mechanism which can be of any type, pyrophoric stone, piezoelectric quartz or other, is arranged to be actuated at the same time, just before or just after the control lever 5 in the direction of the opening of the valve burner 4.
  • lighters of this type child-proof comprising, below the rear end 5b of actuation of the lever 5, retractable stops intended to limit the pivoting in the direction of opening of the valve burner 4, the requirements for automatic mounting of these lighters linked to the conditions of manufacture of their constituent elements, make it inevitable that there is play between the lever 5 and the retractable stops, play which makes it possible to open the valve burner 4 despite the presence of the stops.
  • a second means is provided. elastic capable of generating a second closing force of the valve burner 4, independent of the first, mounted in series with it to act in the same direction but whose force is less than that of the first but greater than that generated by the fuel pressure to open the valve burner 4.
  • the second elastic means keeps the valve burner 4 in the closed position until it is, in turn, deactivated by continuing to pivot the lever 5 in the aforementioned direction.
  • the angular travel of the lever 5 corresponding to the opening of the valve burner 4, or neutral travel depends on the deflection of the second elastic means corresponding to the balance of its force with that generated by the gas pressure upstream of the valve burner 4, but this deflection is easy to determine according to the nature of the second elastic means.
  • the front end 5a, shaped as a crown, of the lever 5 is partially separated from the rest of this lever by a vertical notch 17, opening upwards, the connection between the two thus produced segments of this lever being provided only by a lower bridge 18 of flexible and elastic material such as plastic in which the lever 5 is made, in one piece, by molding or injection.
  • This lower bridge 18 acts as an elastic hinge, allowing the elastic deformation of the lever 5, as shown in Figure 1, and therefore constitutes the second elastic means.
