Definitions

  • the technical field of the invention is that of containers capable of receiving a propellant charge and more particularly that of the containers used in the large caliber or tank artillery.
  • Modular cylindrical containers have already been defined and produced of combustible material. Thanks to their rigidity, such containers are easier than traditional powder sachets.
  • Patent FR9101499 describes a container connecting device which comprises on the one hand a sliding ring and on the other hand hook-and-loop fastening means arranged on a front face of the container.
  • Such a device is complex and expensive to manufacture.
  • the means proposed are delicate to implement. Indeed, so that the ring can slide it is necessary that the radial positioning of the two containers be correct.
  • the attachment means are active whatever the relative radial position of the two containers. This results in difficulty for position and then join the two containers together.
  • Patent FR1291315 on which the preamble of claim 1 is based describes a detachable coupling for cartridges explosives, the separation of which is effected by means of a wire or cord which makes it possible to manually compress an internal elastic ring.
  • the invention thus provides a container linking device which is simple and cheap. This device ensures easy connection of two front containers their introduction into the chamber of a weapon and a rapid separation of containers without using an additional element, when it is necessary to remove from the room.
  • the invention also relates to a container which can be made integral another container at one of its front faces, by means of such a connecting device.
  • the invention can be applied to the production of modular loads as well as loads in at least two loads, one carrying the main load and its igniter tube and the other the projectile (and possibly, but not necessarily, a secondary charge).
  • the subject of the invention is therefore a device making it possible to join two containers at their front faces and comprising a ring mounted sliding way at the level of a first constriction arranged on a first container and can slide to partially cover a second constriction fitted on a second container, the front end of the ring having an annular spout which ensures axial attachment of the ring on the second container when it comes cover the second constriction, the spout cooperating with a circular redent carried by a ring secured to the second constriction, device characterized in that it includes first means ensuring the detachment of the front end of the ring from the second container when the two containers are placed in a room of a weapon, means which comprise an outer diameter of the ring greater than outer diameter of the container, the ring being liable to deform radially, when it is placed in the chamber of the weapon, so as to adopt a diameter substantially equal to that of the container, this deformation causing the stall of the annular beak of the ring with the circular
  • the device comprises second means ensuring the attachment of an internal part of the ring with the second container when the two containers are in the weapon's chamber.
  • the second means of attachment of the internal part of the ring have a fold arranged on the internal surface of the latter and likely to come into abutment on a flange carried by the ring secured to the second shrinking.
  • the ring will include, at a rear part, a shoulder intended to cooperate with a collar arranged on the first constriction in order to achieve a stop axial and will be made of a plastic material of the Polyoxymethylene type or High density polyethylene or polyamide.
  • the collar will be part of a sub-ring integral with the first constriction, sub-ring on which the ring is slidably mounted.
  • the sub-ring and / or the ring will be made of a plastic material of the type High density polyethylene or polyamide.
  • the sub-ring will include a stop annular allowing the axial connection of the ring with the sub-ring in its position advanced, the shoulder of the ring being positioned between the stop and the annular collar.
  • the fold and the collar will each have a conical bearing, the two conical bearings being complementary and intended to cooperate.
  • the invention also relates to a container, in particular for a propellant charge, intended to be secured to a second container at level of one of its front faces by a securing device, container characterized in that it comprises at least one constriction arranged in the vicinity of the face frontal, constricted intended to receive a ring of external diameter greater than outer diameter of the container and which is liable to deform radially by so as to adopt a diameter substantially equal to that of the container, the ring being sliding rise at the neck, the front end of the ring having a annular spout intended to cooperate with a circular redent arranged on a ring.
  • the constriction will include a sub-ring intended to receive the ring, sub-ring comprising an annular collar intended to cooperate with a shoulder of the ring.
  • the container comprises at least one constriction fitted in the vicinity of the front face, constricted intended to receive a ring having a circular redent intended to cooperate with an annular spout arranged on a ring carried by the second container.
  • a first container 1a is intended to be returned secured to a second container 1b at its front face 2a. This last will then be in contact with the front face 2b of the second container.
  • Each container comprises a cylindrical envelope 3a, 3b produced in a combustible material such as nitrocellulose, cardboard or a mixture cardboard / nitrocellulose.
  • the envelopes are closed by end caps 4a, 4b which are also made of a combustible material.
  • the caps are made integral envelopes by gluing at the cylindrical surfaces 5a, 5b.
  • the containers 1a and 1b are shown here partially. They are intended receiving a propellant charge in grains or sticks (not shown).
  • the container 1b carries at its other end a projectile (not shown) which will be made integral with the envelope 3b by a connecting ring (for example similar to that described by patent FR8712484).
  • the container carries at its other end a base (not shown) provided with a igniter tube (see for example patent FR9101499 which shows the fixing of such a base on the envelope).
  • the stopper 4b carries a bowl 6 with a frustoconical profile which is placed in the center of the front face 2b.
  • the stopper carries a bulge 7 with a frustoconical profile which is placed in the center of the front face 2a.
  • the frustoconical profiles of the bowl 6 and the bulge 7 are complementary and are intended to cooperate with each other to allow a relative radial positioning of the two containers before their assembly.
  • Axial openings 22a and 22b are arranged at the front faces 2a and 2b of the containers. These openings facilitate the transmission of flame from one container to another when igniting the propellant charge. They are obstructed, in a known manner, for example by means of combustible sheets (not shown).
  • the end caps 4a and 4b each carry a constriction 8a, 8b, the maximum diameter D1 is about 10 mm less than the outer diameter D2 of the container, the diameter D2 of the container corresponding substantially to the diameter internal chamber of a weapon in which it will be placed.
  • the constriction 8a of the container carries it a sub-ring 9 fixed for example by collage.
  • This sub-ring is made of plastic, for example of the type High density polyethylene or polyamide.
  • the sub-ring 9 carries on its external cylindrical surface 10 an annular collar 11.
  • a ring 12 is slidably mounted on the sub-ring 9. It is also made of plastic such as Polyoxymethylene or Polyethylene High density or polyamide. It has a shoulder 14 arranged at the level a rear part 13 and a fold 16 at an internal surface and on the side of a front end 15.
  • the shoulder 14 and the fold 16 have a diameter greater than the external diameter 10 of the sub-ring 9, which allows the sliding of the ring on the sub-ring.
  • the shoulder 14 is intended to abut on the annular collar 11 so as to limit the axial displacement of the ring 12 relative to the sub-ring 9.
  • the ring 12 is put in place by elasticity on the sub-ring before gluing the latter on the neck 8a.
  • the ring 12 cannot plus be separated from container 1a, which avoids its loss and simplifies logistics.
  • a mounting chamfer on the rear face of the shoulder 14 of the ring and on the face front of the annular collar 11 of the sub-ring.
  • the ring 12 has an outer bead 17 of diameter D3 which is greater the container diameter D2 of the order of 2 to 3 mm.
  • the ring also has, at its front end 15, a spout ring finger 18.
  • the container 1b carries on its neck 8b a ring 19 fixed for example by collage.
  • This ring is also made of plastic, for example of the type High density polyethylene or polyamide.
  • the ring 19 carries a circular redent 20 intended to cooperate with the spout annular 18 of the ring 12. It also includes a flange 21 intended to cooperate with the fold back 16 of the ring 12.
  • FIG. 2 represents the two containers 1a and 1b assembled by the ring 12.
  • the two containers were brought into contact with each other at their front faces 2a, 2b.
  • the bowl 6 and the bulge 7 then ensure the alignment of the containers and thus constitute means ensuring good radial positioning of the two containers.
  • the shoulder 14 of the ring 12 finds itself in abutment against the collar annular 11 of the sub-ring 9.
  • the collar 11 thus ensures the axial immobilization of the containers 1A and 1b when the spout 18 of the ring 12 is hooked to the circular redent 20 of ring 19.
  • the dimensions of the ring, the sub-ring and the ring will be defined from so that this axial immobilization can be achieved. So when the containers are in contact at their front faces and that the spout 18 is attached to the redent 20, the shoulder 14 abuts against the collar 11.
  • the collar 21 has an external diameter substantially smaller than the diameter outer 10 of the sub-ring 9 so as not to interfere with the fold 16 during the translation of the ring 12.
  • the material of the ring, the sub-ring and the ring fragments when igniting the propellant charge under the effect of gas pressure.
  • areas of weakness obtained by example by localized heating or machining.
  • FIG. 3 represents the two containers 1a and 1b assembled by the ring 12 and placed inside a tube 23 of a weapon.
  • ring 12 which has a diameter in the rest position D3 greater than the diameter D2 of the containers, deforms radially so elastic in order to adopt the internal diameter of the chamber 24.
  • the deformation of the ring causes the recess of the spout 18 with the redent circular 20 then a slight retreat of the ring with respect to the containers until the fold 16 comes substantially into abutment against the collar 21.
  • the dimensions of the ring will be defined so that the deformation of this by reducing its external diameter D3 can ensure the release of the attachment of the spout 18 with the redent 20 and the advance of the fold 16 in the vicinity of the flange 21.
  • FIG. 4 represents the two containers 1a and 1b during the phase of unloading.
  • FIG. 5 represents the two containers 1a and 1b at the end of the phase of unloading.
  • the two containers are thus removed from the barrel barrel chamber in one single operation and end up not being interdependent of each other, which allows a faster maneuvering, for example in the event of the exchange of only one of the containers or return to storage position after non-use.
  • FIG. 6 represents a modular type container according to the invention. This container made of combustible material is intended to be assembled with other completely identical containers in order to constitute a load artillery propellant.
  • It consists of a combustible envelope 3, closed at one end by a plug 4a which carries a first constriction 8a and at the other end by a plug 4b carrying a second constriction 8b.
  • the first constriction 8a carries a sub-ring 9 and a ring 12.
  • the second constricted 8b carries a ring 19.
  • the envelope cylindrical was closed by two fuel caps carrying a neck. He will be as a variant, it is possible to produce at least one stopper from a single piece with the envelope. We proceed for this to a shaping of the envelope in a suitable mold. This avoids a delicate fixing operation by gluing the cap on the envelope.
  • weakening zones on the latter obtained for example by localized heating or by machining.
  • Figure 7 shows two containers according to a second embodiment.
  • the sub-ring 9 has on its cylindrical surface outer 10 and near the collar 11, an annular stop 25.
  • the stop 25 allows the axial retention of the ring 12 when the latter is in advanced position, the shoulder 14 of the ring having been received between the collar 11 and the stop 25.
  • the stop 25 has a chamfer at its rear part which facilitates the passage of the ring 12.
  • the ring can also carry a complementary chamfer (not shown) on the front part of the shoulder 14.
  • Such an embodiment has the advantage of being able to be used in a automatic loading device without requiring prior assembly of the two containers, only the translation of the ring 12 is necessary in the advanced position. In effect, the ring being in its advanced position, the container is placed in the automatic loading followed by container 1b. The ring 12 cannot move back thanks to the stop 25, the container 1b is automatically secured to the container by hooking the spout 18 of the ring 12 on the redent 20 of the ring 19.
  • the collar 21 of the ring 19 has, in this second embodiment, a conical bearing 26 complementary to a conical bearing 27 produced at the level back of the fold 16 of the ring 12.
  • the two complementary conical bearings 26 and 27 improve the holding mechanics of the fold back link 16 / flange 21 when removing the containers. They maintain the connection during removal as long as the tractive effort is effective.
