Definitions

  • the present invention relates to a safety lighter, with delayed gas opening, of the type comprising, arranged in its body, a normally gaseous fuel tank, stored in the liquid phase, a pressure reducer-evaporator located between the tank and a burner- valve closing the gas outlet 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 so that the release of the gas does not take place until the moment of production of the spark, in the case where the latter is posterior to the start of lever operation, which promotes ignition, but also, so that the valve opening time 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 rock the lever in the direction of opening of the valve and, in the absence of a neutral stroke, such a tilting inevitably leads to an unnecessary loss of gas.
  • valve is opened only 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 locking 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 to 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 locking 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.
  • a lighter of the aforementioned type is known in which the opening of the valve by the control lever is delayed by the adaptation of a second elastic means, interposed between the first and the valve , intended to act on the valve, in series and in the same direction as the first, that is to say in the direction of closing the valve, but with a force less than that of the first elastic means but 'greater to that generated by the pressure of the gas and tending to open the valve.
  • the first elastic means maintains 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 deactivation of the second elastic means frees the valve enough to allow it to be opened.
  • 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 rear end of actuation and this is achieved by the fact that the anterior end of the control lever which completely or partially surrounds the upper end of the valve burner is divided, by a V-shaped slot, into two superimposed segments, linked to each other by a web of elastic material, acting as an elastic hinge , and the lower one of which is normally inclined downward but can be resiliently brought 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 second elastic means is constituted by an axially deformable annular piece, surrounding the upper end of the valve burner to which it is axially connected and forming the shoulder against which the front end of the control lever is applied which, under the action of the first elastic means, normally maintains the valve burner in the closed position.
  • the annular part forming the second elastic means is constituted by an elastically deformable washer, such as in spring steel, made integral with the upper end of the valve burner to serve support shoulder at the front end of the control lever, to keep the valve in the closed position.
  • the annular part forming the second elastic means consists of a washer of elastically compressible material such as a foam of plastic material, such as an elastomeric resin, a rubber or the like. similar resin, fitted on the upper end of the valve burner to serve as a support shoulder at the front end of the control lever, to hold the valve in the closed position.
  • the annular part forming the second elastic means is constituted by a helical spring surrounding the upper end of the valve burner and normally compressed between the shoulder of the valve burner and the end front of its control lever.
  • 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 means. elastic of this lighter, constantly tends to rotate the lever 5 in the direction of arrow 9, that is to say in the direction in which its front end 5a keeps the valve burner 4 in the closed position by pressing against a shoulder 4c of this valve burner 4.
  • the ignition mechanism of this lighter 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 a play between the lever 5 and the retractable stops, play which makes it possible to open the burner - valve 4 despite the presence of the stops.
  • a second elastic means is provided between the first elastic means intended to guarantee the closing of the valve burner 4 and constituted, in the examples illustrated in the drawing, by the helical spring 8 and the valve burner 4, a second elastic means is provided. able to generate 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 pressure of the fuel aimed 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 second elastic means consists of an axially deformable annular part, surrounding the upper end of the valve burner to which it is axially linked and forming the shoulder against which the front end of the control lever is applied, which under the action of the first elastic means, normally maintains the valve burner in the closed position.
  • the annular part forming the second elastic means consists of an elastically deformable washer 11, made of spring steel or other suitable material, secured to the upper end 4b of the valve burner 4 and the upper face of which constitutes the shoulder 4c against which the front end 5a of the lever 5 is normally kept applied by the force of the helical spring 8.
  • the front end 5a of the latter is provided with lower bosses 5′a, diametrically opposite.
  • the variant embodiment shown in FIGS. 3 and 4 differs from this first example in that the elastically deformable washer 11 is replaced by a washer 12 made of an elastically compressible and preferably non-flammable material, such as foam. synthetic resin or made up of a helical spring.
  • the operation of this lighter is directly comparable to that of the first example.
  • the annular part forming the second elastic means consists of a helical spring 13 surrounding the upper end 4b of the valve burner 4 and which is normally compressed between a rigid shoulder 4c of this valve burner and the front end 5a of the control lever 5.
  • the force generated by the washer 11 or 12 or by the spring 13 is less than that generated by the spring 8 which causes its maximum deformation or compression, but greater than that generated by fuel pressure and aimed at opening the valve burner 4.
