Definitions

  • the technical field of the invention is that of containers capable of receiving a propellant charge and more particularly that of containers used in the field of large caliber or tank artillery.
  • Modular cylindrical containers which have been made of combustible material have already been defined. Thanks to their rigidity, such containers are easier to use than traditional powder sachets.
  • Patent FR2672672 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, for the ring to slide it is necessary that the radial positioning of the two containers is correct. However, the hooking means are active whatever the relative radial position of the two containers. This results in a difficulty in positioning and then making the two containers integral.
  • the invention thus provides a container connection device which is simple and inexpensive. This device makes it possible to easily ensure a rigid and reliable connection of two containers without additional parts and while allowing separation just as easy. Depending on operational needs, this device can also be easily taken out of service.
  • the invention also relates to a container which can be made integral with another container at one of its front faces, by means of such a connecting device.
  • the invention can be applied as well to the realization of modular loads as of 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 a device making it possible to secure two containers at their frontal faces, device characterized in that it comprises, on a first container, at least three hooks, axially displaceable and regularly distributed angularly, which each include a spout intended to be positioned at the level of a circular groove arranged on a second container, the spout having a profile cooperating with a complementary profile carried by the circular groove, so as to ensure an axial locking of the containers.
  • the profile carried by the circular groove has at least one substantially conical surface whose apex of the cone is oriented towards the front face of the second container.
  • the conical surface of the complementary profiles has a half-angle at the top of the order of 80 °.
  • Each hook can be translated into a housing arranged on the external surface of the first container, a housing which provides axial guidance for the hook.
  • the hook has a tenon which can move axially inside a hole made on the external surface of the first container to come into abutment against a flange of a cover secured to the first container and also an elastic fold.
  • the hook has a heel which, after axial displacement of the hook until the tenon reaches the stop against the cover, is brought back by the elastic fold in abutment against the flange, the tenon and the heel enclosing the flange so as to ensure the axial locking of the hook.
  • the hooks will be secured to a threaded ring mounted on a threaded cylindrical part of a cover secured to the first container.
  • the hooks will be made of a plastic material such as Polyoxymethylene or High Density Polyethylene or polyamide.
  • the invention also relates to a container, in particular for a propellant charge, intended to be made integral with another container at one of its front faces by a device according to the invention, it is characterized in that 'It comprises at least one circular groove whose profile is intended to cooperate with a complementary profile carried by a hook secured to the other container.
  • This container will have a bottom integral with an envelope and having a groove.
  • the invention also relates to a container, in particular for a propellant charge, intended to be made integral with another container at one of its front faces by a device according to the invention, container characterized in that it comprises at least three housings arranged on its external surface and intended to each receive a hook.
  • the housing will be produced on an envelope of the container and on a lid integral with the envelope.
  • the cover will have a collar on a front part of which open the housings.
  • the container will include a cover secured to an envelope and having a threaded cylindrical part intended to cooperate with a threaded ring carrying hooks.
  • a first container 1a is intended to be made integral with a second container 1b at its front face 2a. The latter will then be in contact with the front face 2b of the second container.
  • the two containers are shown here in half-view / half-section, the upper part being cut axially and the lower part being shown in external view.
  • Each container comprises a cylindrical envelope 3a, 3b made of a combustible material such as nitrocellulose, cardboard or a cardboard / nitrocellulose mixture.
  • the containers 1a and 1b are shown here partially. They are intended to receive 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 casing 3b by a connecting ring (for example similar to that described by patent FR2620214).
  • the container carries at its other end a base (not shown) provided with an igniter tube (see for example the patent FR2672672 which shows the fixing of such a base on the envelope).
  • the container 1a comprises, on the side of its front face 2a, a cover 4 made of plastic material of the high density polyethylene or polyamide type, which is made integral with the envelope 3a, for example by gluing, at a cylindrical surface 5a .
  • the cover 4 comprises a flange 9a against which abuts an end 10a of the envelope 3a.
  • the container 1b comprises on the side of its front face 2b, a bottom 6 made of plastic material of the high density polyethylene or polyamide type.
  • the bottom 6 is made integral with the envelope 3b, for example by gluing, at a span cylindrical 5b.
  • One end 10b of the envelope bears against a flange 9b of the bottom 6.
  • the covers and the bottoms are closed by end plugs 7a, 7b which are also made of combustible material.
  • the plugs 7a, 7b are made integral respectively with the cover 4 and the bottom 6, for example by gluing. They have axial openings 8a and 8b intended to facilitate the transmission of flame from one container to another when the propellant charge is ignited. These openings are obstructed in a known manner by means of combustible sheets (not shown).
  • the container carries the hooks 11 made of plastic material of the polyoxymethylene or high density polyethylene or polyamide type.
  • the hooks which here are six regularly angularly spaced, are intended to secure the two containers. They are inserted into housings 12 which allow their movement in an axial direction of the container and guide them during this movement.
  • Each housing 12 arranged on the external surface of the container consists of a lumen 13 produced in the wall of the envelope 3a and opening at the end 10a, as well as a longitudinal groove 14 produced in the cover 4.
  • Figures 2a and 2b show an embodiment of the cover 4 in two views, Figure 2a being a right view of Figure 2b which is a half section / half view.
  • the cover 4 comprises, at the cylindrical surface 5a, six longitudinal grooves 14 regularly spaced angularly. These open out on the side of the front face 2a by crossing the flange 9a. Such a cover is obtained by molding
  • Figures 3a and 3b show an embodiment of a hook 11 in two views, Figure 3b being a top view of Figure 3a.
  • This hook has a width L slightly less than the width of the longitudinal groove 14 of the cover 4 and comprises a lug 16 of width substantially less than the width of the opening 13 of the envelope, in order to allow the axial displacement of the hook in the housing 12.
  • an elastic fold 15 intended to ensure axial retention of the hook in the housing 12 by radial wedging of the latter between the internal surface of the envelope and the bottom of the longitudinal groove 14.
  • the hook has at the other end a spout 20 intended to be inserted at the level of a circular groove 18 produced on the bottom 6 of the second container 1b.
  • the spout has a length less than the width of the circular groove 18.
  • the spout 20 comprises a profile 19a intended to cooperate with a second complementary profile 19b produced at the level of the circular groove 18.
  • These two profiles each consist of a conical surface 25a, 25b whose half-angles at the top x are substantially identical , less than 90 ° and preferably of the order of 80 °.
  • the profile 19b is such that the top of the cone generated by the conical surface 25b is oriented towards the front face 2b of the container 1b.
  • FIG. 4 represents the two preceding containers 1a and 1b linked by the securing device according to the first embodiment.
  • the containers were brought into contact with each other at their front faces 2a, 2b.
  • the alignment of the containers can be achieved by bowls and bulges of complementary shape produced at the plugs 7a, 7b, as described in patent FR2711209 (not shown here).
  • the hooks 11 have been moved axially so that the two complementary profiles 19a, 19b of the hooks and the groove 18 cooperate.
  • the axial displacement of each hook is achievable by manually exerting support at the elastic fold and sliding the hook towards the front faces 2a, 2b.
  • each hook is ensured by the presence of the lug 16 and the heel 17 which, under the action of the elastic fold 15 encloses the flange 9a of the cover 4 to form stops.
  • the hooks thus ensure a rigid and reliable connection of the two containers.
  • the spout 20 has a slope 23 of conicity substantially equal to that of a conical bearing 24 produced on the bottom 6.
  • the plug 7a can be an integral part of the cover 4 so as to form only one and the same part. It is the same for the bottom 6 and the plug 7b.
  • the cover carrying the hooks can also be secured to the container carrying the projectile and the bottom to be secured to that carrying the base.
  • the hooks 11 have an external profile substantially equal to the external diameter of the containers 1a, 1b. Thus when they are in their locked position (fig 4), they are held in this position by the internal surface of the chamber of the weapon (not shown). Such an arrangement increases the rigidity of the connection and ensures the possibility of extracting from the chamber the two containers linked to each other.
  • the disassembly of the link is very easy, it suffices to release each hook 11 from its groove 18 by grasping it with the hand.
  • the elasticity of the hook material facilitates its release.
  • Figure 5 shows before securing two containers according to a second embodiment of the invention.
  • the container 1b has on the side of its front face 2b, a bottom 6 identical to that of FIG. 1.
  • the container 1a comprises, on the side of its front face 2a, a cover 4 made of plastic material of the High Density Polyethylene or polyamide type, which is made integral with the envelope 3a for example by gluing at a cylindrical surface 5a.
  • the cover 4 comprises a flange 9a against which abuts an end 10a of the envelope 3a.
  • the cover 4 has a threaded cylindrical part 21 on which a threaded ring 22 is engaged.
  • the ring 22 has at its front periphery hooks 11, the spout 20 of which is identical to that described previously in FIGS. 1 to 4.
  • the hooks here six in number, are intended to secure the two containers by cooperation of the profile 19a of the hook and of the complementary profile 19b carried by the bottom 6.
  • FIG. 6 represents the two preceding containers 1a and 1b of FIG. 5 linked by the securing device according to this second embodiment of the invention.
  • the axial displacement of the hooks 11 is ensured here by means of the threaded ring 22, which by screwing and unscrewing, can translate relative to the cover 4.
  • the hooks 11 can then be positioned in the circular groove 18 via of their beak 20, as shown in FIG. 6.
  • This second embodiment has the advantage of being able to secure the joining of two containers in a single operation thanks to the ring 22 which positions all the hooks at once in the circular groove 18 and allows tightening after positioning the spouts. which increases the rigidity of the connection.
  • FIG. 7 represents a container of modular type according to the invention.
  • This container made of combustible material, is intended to be assembled with other containers which are completely identical to it in order to constitute a propellant artillery charge.
  • It consists of a combustible envelope 3, closed by two plugs 7a and 7b.
  • One end of the container carries a bottom 6 having a groove 18, the other end carries a cover 4 fitted with hooks 11.
  • the hooks are left in their storage position in which they remain because the elastic fold 15 ensures the axial retention of each hook in its housing by wedging radial.
  • the hooks are moved axially until their beak is hooked into the groove 18 of another container.
