Definitions

  • the present invention relates to a fastening system intended to allow the fastening 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 belonging respectively to the convex dome and to the concave cup determine an annular rim inside and under which the fastening members of the fixing system mentioned above can be snapped.
  • the device attached to the cartridge must be re body with the latter, which means that the fixing system used must provide a rigid connection of the device on the cartridge, so as to avoid any relative movement of these two elements, likely to cause a leakage of combustible gas.
  • the fixing system used must provide a rigid connection of the device on the cartridge, so as to avoid any relative movement of these two elements, likely to cause a leakage of combustible gas.
  • these devices may fall accidentally, it is essential that the effort required to separate the device from the cartridge is less than that necessary to serve the cup of the upper dome of the cartridge, so that these drops cause separation. of the device from the cartridge, not a leakage of combustible jaz at the cup-dome junction.
  • each hooking member preferably comprises a pushing element on which the lower part of the central core bears.
  • 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 bringing 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 container, 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 la with a convex upper dome 1b; a concave cup 1c is set on the dome 1b and forms with it an annular bead lc.
  • a sampling valve 1a is arranged in the center of the cup 1c.
  • 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 1c of the cartridge 1.
  • the system according to the invention is also composed of an annular part 3 produced in the form of a cylindrical bell 6 surmounted by a tubular and central chimney The latter comprises a thread cooperating with the thread of the core 4.
  • the junction of the chimney and the upper face 6a of the bell 6 is provided with four openings 2 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 claw 9 (or hooking member) 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 claw 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 facing downwards passing through the corresponding opening 8, followed by a hooked heel 9c outwardly followed by a tab 9d (forming a locking means) oriented towards the center and obliquely to the horizontal.
  • This tab 9d which extends at least partially under the lower part of the core 4, constitutes a pushing element of the corresponding claw.
  • the set of heels 9c of the claws 9 is roughly situated on a circumference of diameter slightly greater than that inside of the bead 1d.
  • the device 5 of the core 4 acts on the valle of the cartridge 1 to open it so that the gas that contains a cartridge can s '' flow through a channel 5a towards 1 active part of the device 2 which com usually takes a stopcock.
  • the device 2 there is therefore a rigid attachment of the device 2 relative to the cartridge 1 by positive locking of the claws 9 under the bead adding it to the elastic snap-fastening of the same claws.
  • a groove 4a is made located on the side of the core associated with the device 2 and practiced in the tubular chimney 7 of the annular part 3 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 is less than the outer diameter of the 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 core 4 from acting on the legs 9d of the claws 9.
  • FIG. 8 an alternative embodiment of the fastening members which are each produced in the form of a pivoting element comprising at least two teeth.
  • the annular part 3 no longer has the openings 8, but the chimney 7 is extended downwards by an internal skirt 11 which extends concentrically to the periphery of the bell 6.
  • the skirt 11 which has a certain thickness is provided with '' at least two parallel notches 11a, Ilb diametrically opposite through which extends an axis, produced in the form of a cylindrical pin 12 fixed to the skirt 11 by any means not shown, for example by riveting, and around which is mounted with free rotation a roller 13 forming the aforementioned pivoting element, comprising four teeth 14 regularly distributed around its periphery.
  • the means of making the annular part 3 of the 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 throat 4a of the nucleus.
  • the skirt 11 is provided with an internal groove 11c in which is engaged an elastic circular rod 16 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 range 4b therefore significantly reduces the threaded length of the 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 tapped part of the nut 17 and which extends towards the bottom by a second frustoconical 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 24 forming a hooking heel 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 heels 24 can be engaged elastically under the inner part of the bead Id of the cartridge 1. If the annular part 3 is angularly immobilized by means of the fins 17a, 17b and that the core 4 is screwed into said part, the chamfer 4c of the core comes at the end: u screwing bear against the frustoconical bore 22, which causes the jaws 20 to move in a centrifugal manner so that their heels 24 come to hang under the bead ld of the cart: uche 1, in the same way as the heel 9c of the claws 9 described: n reference to fig. 3.
  • the hooking members are released from the positive locking action so that the fixing system can easily be released cartridge.
  • the annular part 3 in a sufficiently rigid and elastic plastic material.
  • polypropylene as a material capable of being particularly suitable for its production.
