Definitions

  • the present invention relates to a fixing system intended to allow the attachment of a gas appliance and a cartridge of pressurized fluid. It relates more precisely, but not exclusively, to a fixing system with a cartridge of the "aerosol" type containing a liquefied combustible gas, for example butane.
  • these cartridges generally comprise a cylindrical body with a convex upper dome, a concave cup crimped onto the upper dome, a sampling and / or filling valve housed in the center of the concave cup.
  • the two crimped edges respectively belong to the convex dome and to the concave cup determine an annular rim inside and under which can snap the fastening members of the fixing system mentioned above.
  • positive locking means is meant a means distinct from the other members of the fixing system, making it possible to reversibly perform a new function, namely to bring the claw of each hooking member under pressure against the internal wall of the annular bead cartridge.
  • a cartridge 1 of pressurized fluid such as liquefied butane, affecting the shape of an aerosol reservoir, as well as a fixing system according to the invention intended to allow a gas appliance 2 to be associated with said cartridge.
  • the cartridge 1 comprises a cylindrical body 1 a with a convex upper dome 1 b; a concave cup 1 c is set on the dome 1 b and forms with it an annular bead 1 d.
  • a sampling valve 1 is placed in the center of the cup 1 c.
  • the device 2 is provided with an externally threaded central core 4 comprising in its center a known sampling device 5 intended to cooperate with the valve 1e of the cartridge 1.
  • the system according to the invention is further composed of an annular part 3 produced in the form of a cylindrical bell 6 surmounted by a tubular and central chimney 7.
  • the latter includes a thread cooperating with the thread of the central core 4.
  • the junction of the chimney and the upper face 6a of the bell 6 is provided with four openings 8 arranged at 90 ° from one another and which extend partly in the upper wall of the bell, part in the chimney 7
  • Each of the openings allows the passage of a hooking member 9 shaped like a claw and produced in the form of a spring steel blade suitably bent and which is riveted at one end on the upper face 6a of the bell 6
  • Each fastening member 9 comprises a rectilinear part 9a secured to the face 6a by means of a rivet 10 and which is extended by a part 9b turned downward through the corresponding opening 8, followed by a heel of hooking 9c cambered outwards, followed by a tab 9d oriented towards the center and obliquely to the horizontal.
  • This tab 9d which extends at least partially under the lower part of the central core 4, constitutes a thrust element of the corresponding hooking member 9.
  • the set of heels 9c of the fastening members 9 is roughly situated on a circumference of diameter slightly greater than that inside of the bead 1 d.
  • the device 5 of the central core 4 acts on the valve 1 of the cartridge 1 to open it so that the gas contained in the cartridge can flow through a channel 5a towards the active part of the device 2 which generally comprises a stopcock.
  • the device 2 which generally comprises a stopcock.
  • the fastening members 9 under the bead 1 d being added to the elastic snap-fastening of the same members.
  • a groove 4a located on the side is made in the central core of the central core associated with the device 2 and in the tubular chimney 7 of the annular part 3 there are at least two slots 7a, 7b oriented parallel to the upper end of said chimney.
  • the top of this chimney can be deformed above the slots 7a, 7b so as to form two projections 7c, 7d (Fig. 6 and 7) facing towards 'interior and whose distance between technicians is less than the outer diameter of the central core while being slightly greater than that of the bottom of the groove 4a.
  • the height of the latter is, of course, provided so that the projections 7c, 7d do not prevent the free end of the central core 4 from acting on the lugs 9d of the attachment members 9.
  • FIG. 8 there is shown in fig. 8 an alternative embodiment of the fastening members 9 which are each produced in the form of a pivoting element comprising at least two teeth.
  • the annular part 3 no longer has openings 8, but the chimney 7 is extended downwards by an internal skirt 11 which extends concentrically with the periphery of the bell 6.
  • the skirt 11 which has a certain thickness is provided with at least two parallel notches 11 a, 11 b diametrically opposite through which extends an axis produced in the form of a cylindrical pin 12 fixed to the skirt 11 1 by any means not shown, for example by riveting, and around which a roller is mounted for free rotation 13 forming the aforementioned pivoting element, comprising four teeth 14 regularly distributed over its periphery.
  • the means of making the annular part 3 of the central core 4 non-removable consists of a pin 15 made integral with the chimney 7 and which is engaged transversely in the latter so that it is in the groove 4a of the central core.
  • the skirt 11 is provided with an inner groove 11 c in which the elastic circular ring 16 is engaged, which constitutes the axis of articulation of the rollers 13.
  • the central core 4 has at its lower part a bearing 4b of diameter smaller than that at the bottom of the thread of its threaded part and which ends in a chamfer 4c.
  • the bearing 4b therefore significantly reduces the threaded length of the central core 4.
  • the annular part 3 is produced in the form of a member molded from a suitable plastic material. It comprises a cylindrical nut 17 extending downwards by a socket 18 comprising four radial slots 19 so that this socket is constituted by four independent elastic jaws 20 connected to the nut 17.
  • the socket 18 is provided with a conical bore 21 open upwards following the threaded part of the nut 17 and which extends in the direction of the bottom by a second conical bore 22 with greater conicity; thus is determined on each jaw a pushing element 23 in the form of an oblique surface facing inward.
  • the outer periphery of the sleeve 18, therefore also each of the jaws 20, has a projection forming a hooking heel 24 surmounted by a flange or spout 25.
  • the nut 17 is provided with two fins 17a, 17b intended to facilitate its actuation.
  • the annular part 3 being partially or not screwed onto the thread of the central core 4, the hooking heels 24 can be engaged elastically under the inner part of the bead 1 d of the cartridge 1. If the annular part 3 is angularly immobilized by means of the fins 17a, 17b and that the central core 4 is screwed into said part, the chamfer 4c of the latter comes at the end of the screwing to bear against the conical bore 22, which causes a movement of the jaws 20 so centrifugal so that their hooking heels 24 are blocked under the bead 1 d of the cartridge 1, in the same way as the heel 9c of the hooking members 9 described with reference to FIG. 3.
