Definitions

  • the present invention relates to a system for fixing a gas reservoir with a perforable wall to a head for sampling this gas. It relates more particularly to apparatuses for combustion of a pressurized combustible gas available in liquefied form in interchangeable lost packaging known in practice under the name of cartridges.
  • the invention refers to portable cooking, lighting, heating and welding devices supplied from butane cartridges.
  • each device envisaged previously comprises a gas sampling head equipped with a tap and which is screwed into an opening located in the center of a support such as a bell capable of enclosing the cartridge. More specifically, the head in question is screwed into the tapped hole of a central piece fixed itself in the hole of the support.
  • An axial perforation means for example a flat point, is disposed axially in the head so as to perforate the cartridge inside an annular seal or the like which is applied in leaktight manner against the central part of the upper wall of the cartridge.
  • a fixing system constituted by a support intended to receive the cartridge, comprising at least two holding pieces or stirrups each shaped to enclose this cartridge, and which are movable one with respect to the other and more precisely articulated to each other by an inner intermediate piece, a first stirrup is articulated on an upper central piece, while the second can be housed at the top of said central piece in a gutter provided for this purpose; with all these provisions the support can open and close on the cartridge.
  • the central part of the support has a tapped hole in which is screwed on the axial end, externally threaded, of a gas sampling head with tap.
  • the annular seal necessary for sealing with the cartridge is fixed below the central part of the support so as to surround its tapped hole.
  • This seal is also in leaktight contact with an axial perforation trocar of the cartridge, which is part of the gas sampling head, so that the space surrounding the latter is isolated from the outside of the device.
  • an apparatus in accordance with French patent 1,419,891 includes a security system consisting of a plate articulated on the central part of the support, adjacent to the gutter, on the side opposite the tapped hole, this plate being shaped to come surround partially this hole.
  • the gas sampling head has an enlarged base intended to come to bear, by screwing on the support, against the wafer.
  • any user can manually bring the second stirrup into the gutter provided on the central part of the support, without using the tongue, that is to say without folding the latter. Therefore, without having brought the tongue against the aforementioned central part, the user can normally screw on the gas sampling head and thus puncture a full cartridge. In this case, the security system not having been put in place, it remains completely inactive, and cannot play any role. And, in the opposite direction, the user can open the support without the gas intake head having been unscrewed.
  • the security system in accordance with French patent 1 419 891 does not provide the user with all the guarantees necessary against false operations, essentially because it is a system fitted to the devices in question, requiring a positive action on the part of the user, independent of the positioning and of the perforation of the cartridge in the support.
  • the present invention aims to remedy the drawbacks raised above, and more precisely it relates to a system of the same type as that shown by the prior art, but for which the desired security means are integrated and somehow "blend" into the system itself, so that the mere installation of the gas sampling head is sufficient to obtain the expected safety effect.
  • the present invention proposes to provide a fastening system comprising as few parts as possible, which can be handled in a simple manner by any user of average attention, so as to avoid as much as possible any false maneuver.
  • the invention aims to make apparent the existence of any false maneuver, such as setting in place of the gas sampling head on only part of the support.
  • the at least partial screwing of the gas sampling head onto the support constitutes sufficient means for locking the two holding pieces relative to the other in the closed position of the support on the cartridge , while the total unscrewing of the gas sampling head constitutes a necessary means for releasing one with respect to the other, the two holding pieces in the open position of the support.
  • support within the meaning of the present invention, is meant any set of parts whose arrangement has the function of at least partially containing and centering the cartridge.
  • a support according to the invention may comprise different parts, in particular two holding pieces.
  • holding part within the meaning of the present invention, is meant any part whose shape allows the cartridge to be clamped directly or indirectly.
  • the solution according to the invention makes it possible to remedy the drawbacks encountered in the prior art, since security thus becomes intrinsic, and no longer extrinsic to the means for installing and removing the cartridge.
  • the present invention is also useful in the context described in French patent application 77 24136 filed on 29.7.77 by the Applicant. According to this request and for various technical reasons explained in the latter, it has been proposed to provide the support with at least three male elements, angularly distributed regularly around its axis, and to provide each cartridge with at least three corresponding female elements. , distributed angularly, regularly around the axis of said cartridge, and intended to engage in said male elements.
  • a fixing system according to the invention almost automatically encourages the user to put the female elements of the cartridge, by rotation of the latter, in correspondence with the male elements of the support, to completely close it.
  • a fixing system 3 is used in accordance with the present invention and which constitutes a preferred embodiment of the latter. It will be noted that the cartridge 1 has a domed top provided in its center with a concave cup 1b.
  • the fastening system 3 is produced in the form of two symmetrical shells referenced 4 and 5, or retaining pieces completely enveloping the cartridge 1 , which are hinged together, around a same horizontal axis located at their bases 4a, 5a.
  • These bases correspond to a slightly larger diameter portion of each of the shells 4 and 5. They each have a fallen edge 4b, 5b oriented transversely relative to each shell and on which rests the lower bead 4c of the cartridge 1, as we ra Explain to better further.
  • Each of the bases is extended by two ears 4c, 4d respectively 5c, 5d which come two by two to be placed side by side so that each of the perforations formed in the center of each ear come in correspondence.
  • the pairs of ears 4c, 5c and 4d, 5d are assembled by means of a rivet which leaves a certain play between these ears so as to allow an easy tilting of the two shells relative to one another.
  • Each shell has a neck 4e, 5e and a horizontal and transverse wing 4f, 5f which is in the form of a semicircle extended by a central tab determining a projection also semi-circular as is more particularly illustrated in fig . 3.
  • the center 4g of the upper transverse wing 4f is raised and has in its center a cutout 4h present. both a circular shape.
  • the lower transverse wing 5f of the shell 5 comprises in its center an opening 5g with a directly threaded edge situated coaxially with respect to the cut 4h, in the closed position explained below. It is observed that the transverse wing 5f of the shell 5 is in abutment against the internal face of the transverse wing 4f of the shell 4.
  • the cartridge 1 is of the type comprising axial depressions ld, provision is made to provide in the side wall of the two shells 4 and 5 projections 4j, 5j oriented towards the center and which are intended to engage in the corresponding depressions ld of the cartridge 1.
  • each of the transverse wings of the two shells is provided as regards the first with a tapped central opening 9b, while in the second a central cutout 8b has been provided.
  • the cartridge is engaged in one of the latter, its bead resting it against its horizontal edge 8c or 9c, then it is made to pivot the other until the cutout 8b is placed above the tapped opening 9b and concentrically with the latter as shown in FIG. 5.
  • the cartridge has depressions Id, provision is made to provide radial projections oriented towards the center in the two shells 8 and 9 so that the cartridge is immobilized angularly with respect to these shells.
  • the shells have three projections referenced 8d and 9d.
  • the stirrup 11 is established from a strip of spring steel whose two ends are bent to form a hook 11a, 11b and which is arched so as to assign at rest the general shape of a V open downwards.
  • the stirrup is manufactured so as to include in its middle a veil llc, the center of which is provided with a threaded opening lld.
  • the two wings of the stirrup 11 are advantageously rounded in cross section for reasons which will be better explained below. Each of these wings may have a projection lle, llf capable of cooperating with a corresponding depression ld of the cartridge 1.
  • the bell 12 comprises a cylindrical skirt 12a whose lower edge 12b is flared, while its upper part is connected to a transverse wall 12c comprising in its center a cutout 12d with a diameter slightly greater than that of the tapped opening lld.
