Definitions

  • the present invention relates to a lighter of the type comprising a hinged cover hinged on the body of the lighter.
  • the cover is articulated on the body by means of a set of knuckles machined from the mass of these two elements and pivoting around. an axis integral with one of them (generally, the body of the lighter).
  • the body and the cover are generally matched immediately after machining the knuckles.
  • a procedure makes it possible to obtain a particularly precise adjustment, it nevertheless involves a certain number of constraints.
  • this mechanism consisting of parts subject to significant stresses, it is also subject to wear or deformation caused by the shocks to which the lighter is subjected. It must therefore also be possible to proceed without difficulty to replacing said mechanism.
  • this mechanism being intended to maintain the cap in the open position and in the closed position is generally complex, which makes the assembly / disassembly operation of the cap difficult, which, therefore, can only be carried out by a specialized after-sales service.
  • the object of the present invention is to remedy these drawbacks, by proposing a means which makes it possible to improve the assembly and repair of high-end lighters, while allowing a reduction in cost.
  • a lighter of the type comprising a tilting cover pivotally mounted on the body of the lighter by means of two elements secured respectively to said body and to said cover and articulated on an axis of rotation, said cover being maintained in closed position and in open position by a mechanism biased by an elastic means,
  • this lighter being characterized in that, on the one hand, said mechanism is integral of the two elements articulated so as to form a sub-assembly and in that, on the other hand, said sub-assembly is removably fixed at least on the body or on the cover.
  • the present invention therefore has the essential advantage of promoting the maintenance of the lighter since the parts subjected to significant mechanical stresses, and therefore susceptible to wear and deformation, can be replaced in a single manipulation.
  • the exchange of the sub-assembly which can be carried out by a simple mechanical operation such as screwing / unscrewing, will be a much easier operation than the simple dismantling of a cover which, generally, requires the removal of 'a pin.
  • the present invention therefore simplifies a maintenance operation which, until now, could only be entrusted to a specialist.
  • the mechanism for holding the cover in the open and closed position may comprise, for example two links articulated together, on the body and on the lighter, the link articulated on said body being urged by the elastic means and the position of opening of the cover corresponding to the exceeding of the alignment of the articulations of said links.
  • This mechanism may also include telescopic means articulated on the solid elements of the body and of the cover, while the elastic means will comprise a return member for these telescopic means, the open position of the cover corresponding to a position of the axis of rotation of said elements located below the line joining the points of articulation of said telescopic means on said elements.
  • the means of articulations, as well as the opening mechanism / closure will preferably be made of metals of sufficient hardness to give them good resistance to wear and to the various mechanical stresses to which they are subjected.
  • the mechanical qualities of the materials used to make the body and the cover will therefore no longer be critical and it will be possible to use metals neglected until now for this use, because of their poor mechanical qualities, such as, for example , precious metals, since the elements subjected to wear and significant mechanical stresses will be made of a metal of higher hardness.
  • the fact of making the articulated elements as well as the opening / closing mechanism with materials having high mechanical qualities allows, without reducing their strength, to significantly reduce their dimensions and in particular their thickness. Due to this reduced thickness, the elements of the sub-assembly can be machined by techniques that have not been used until now, such as press cutting. This reduces the manufacturing cost of the product.
  • the sub-assembly will be fixed to the lighter by its articulated elements, which may, for example, be housed in a groove made in the edges of the body and the cover. It will thus be possible to conceal from the view of the user the profile of the knuckles and the ends of the axes of rotation.
  • the two articulated elements can advantageously protrude outside the grooves in which they are housed, in order to give the lighter an original ornamental appearance and to facilitate its gripping. They will be made integral with the body and the lighter cover, for example, by screwing.
  • the opening / closing mechanism may be constituted in a manner known per se of two links hinged together and on the two hinged elements, one of the links being urged by an elastic return means such as a spring and the locking position corresponding to a position in which the alignment of the three articulation points of said links is exceeded, the part of the articulation system integral with said cover being shaped so that in the open position of the cover, it is stressed by said elastic return means.
  • the lighter shown in FIG. 1 is of a known type with two parts hinged together, namely a body 1 and a tilting cover 2.
  • the body 1 and the cover 2 are hinged together by a separate piece comprising two branches 3 and 4 joined by a hinge pin 5 and housed in grooves with a U-section, respectively 6 for the body 1 and 7 for the cover 2, these grooves being formed in the rear vertical part, with a narrow section, of these parts.
  • the branch 4 of the articulation system is shaped such that, at its lower part 18, the head 17, pushed by the spring 15 can come to bear there in the open position of the cover.
  • the branch 4 ⁇ of the articulation system integral with the cover 2 ⁇ has a T-shaped cross section, the central part of which is housed in a recess 6 ⁇ on the rear face of the cover. It is the same, of course, the other articulated branch (not shown) and the body of the lighter.
  • the branch 4 ⁇ of the articulation system has a U-shaped cross section and it is a projecting part 20 of the cover 2 ⁇ which is received between the branches of the U.
  • the removable sub-assembly according to the invention could comprise a completely different mechanism than the link system of FIG. 1. It would thus be possible to use telescopic means, known in themselves, such as those which are represented on the Figure 6, which will be referred to below.
  • the sub-assembly according to the invention comprises two branches 3 ⁇ and 4 ⁇ articulated on an axis 23, while the opening / closing mechanism consists, in known manner, of a sheath 25 articulated by means of an axis 27 on the branch 3 ⁇ , a piston 29 articulated on the branch 4 ⁇ by means of an axis 28, and a compression spring 31.
  • the latter is housed in the sheath 25 and exerts a force F on the branch 4 ⁇ in the direction of the two axes 27 and 28.
  • the torque of the force F relative to the axis 23 applies the lighter cover in the closed position, when the axis 23 is above the line joining the axes 27 and 28, and maintains said cover in open position, when axis 23 is below said line.
  • the branch 3 ⁇ is pierced with a threaded orifice intended to receive a tube 22 containing the means (not shown in the drawing) intended to ensure expansion and limitation of the gas flow rate.
  • the tube 22 has a boss 24 bearing, once screwed into the branch 3 ⁇ , on the body 1 ⁇ of the lighter. It thus ensures the attachment of this branch 3 ⁇ , without using means visible from the outside of the lighter.
