• the technical field of the invention is that of ammunition crates and stores for receiving such crates.
• the crates have a volume and a reduced mass. They are lined with ammunition in bands formed of links. They are then placed in the magazine of the weapon and the bands are connected to each other, from one box to another.
• the patent application FR3052247 also describes a turret comprising two side magazines, each store can receive several ammunition boxes.
• This last turret also has the particularity of being able to receive crates introduced vertically or horizontally.
• the patent application FR3052247 proposes to have spacers between two store panels, spacers that delimit the housing for receiving the boxes. Boxes that can be introduced horizontally are also maintained through the back door of the store. Such a solution does not provide sufficiently reliable maintenance in position of a box at a given location. Moreover the spacers interfere with the horizontal introduction of the boxes and, concretely, only two boxes can be introduced horizontally, all the others must be introduced vertically.
• the boxes are reliably fixed at locations that are defined at the weapon system design.

• an ammunition box 1 according to the invention is intended to equip a magazine with a gun turret (not shown).
• This box 1 is substantially parallelepipedal and comprises two end walls 2a and 2b parallel to each other and two side walls 3a and 3b also parallel to each other and perpendicular to the front walls.
• the body 1 comprises a pivoting handle 4 which is formed of two arms 5a and 5b articulated on the side walls 3a and 3b and connected by a handle 6 for the extraction and transport of the body 1.
• Each arm 5a or 5b can rotate on one of the side walls 3a or 3b at an axis 8.
• the axis 8 comprises a mechanical fastener, for example a rod having a threaded portion receiving a nut (not shown).
• the figures, in the form of a broken line, show only the geometric trace of the axis 8.
• the handle 6 is mounted freely pivotally on an axis 7.
• the shaft 7 bears against the body 1 at the notches 9 (see also Figure 5a).
• the handle 6 is then positioned above the internal volume 10 of the body 1 and can pivot freely at this level.
• the handle 6 thus forms a roller for guiding a strip of ammunition (not shown) between a box 1 and its neighbor, while reducing friction.
• one of the arms 5a of the handle 4 has a bulge 11 which is disposed near its axis 8 of pivoting on the wall 3a.
• the bulge 11 is here produced in the form of a prismatic extra thickness directly obtained by machining the arm.
• the bulge could alternatively be a plate 11 attached to one of the arms 5a (glued or welded).
• the bulge 11 (or the plate) is substantially parallelepipedic and has rounded ends 11a.
• bulge and wafer will thus be associated, which is described as applying in fact to a one-piece bulge with the arm or to a wafer attached to the arm.
• Figures 7a and 7b show more precisely the bulge 11 machined in the arm.
• the hole 21 allows the passage of a threaded rod secured to the axis 8.
• the bulge 11 is made in the form of an insert plate, it can simply be pinched on the arm by a nut (not shown) during assembly of the shaft 8.
• the box 1 is intended to be put in place in an ammunition magazine 12.
• This magazine 12 is secured to a gun turret (not shown).
• the magazine 12 is intended to receive several ammunition boxes 1 (here two boxes are shown).
• the magazine 12 comprises at least two panels 13a and 13b which delimit an internal volume 14 that can receive the box or boxes 1.
• the panels 13a and 13b are perforated to reduce their mass. They are connected by a bottom plate 15 and spacer bars 16 also connect them at their upper ends.
• the panels 13a, 13b, the bottom plate 15 and the bars 16 are fixed to each other, for example by welding.
• the panel 13a has a horizontal groove 17 which extends over the entire length of the panel 13a.
• the panel 13a also carries five vertical grooves 18 spaced at regular distances, the distance between two vertical grooves 18 is substantially equal to the width of the side walls 3a, 3b of the body.
• Cylindrical housings 19 are arranged at the end of the vertical grooves 18 and are traversed by the horizontal groove 17.
• the grooves 17 and 18 and the housings 19 are made by milling the panel 13a.
• the width of the vertical grooves 18 is equal to that of the horizontal groove 17 and also to the width 1 of the bulge (or plate) 11 (see Figures 7a and 7b).
• the diameter of the housing 19 is equal to the length L of the bulge (or plate) 11.
• grooves 17 or 18 can guide the bulge (or plate) 11 of the handle 4 of a box 1.
• groove 18 maintains the arms 5a and 5b in their vertical position.
• the bulge (or the plate) 11 when the bulge (or the plate) 11 is positioned in the cylindrical housing 19, the groove 18 no longer holds the vertical arms 5a and 5b and these can tilt and the handle 6 of the handle 4 is then at its low position. Note that in this position, the bulge (or plate) 11 forms an angle of about 45 ° between the vertical and horizontal directions.
• the bulge (or plate) 11 is held by the cylindrical housing 19 whose diameter is substantially equal to the length L of the bulge (or plate) 11.
• the body 1 is thus locked in its position and can no longer move, neither vertically nor horizontally.
• the cylindrical housing 19 and cooperates with the bulge (or the plate) 11 so as to ensure a locking of the body 1 once it is in place, and the handle 6 of the handle 4 tilted in the low position.
• FIG. 5b it is also possible to set up a box 1 in a horizontal direction H. It is sufficient to position the box at one end of the magazine 12 while maintaining the handle 4 with its arms 5a and 5b horizontal. In this case, the bulge (or plate) 11 is positioned in the horizontal groove 17 which maintains the arms 5a and 5b in their horizontal position.
• the bulge (or the plate) 11 When, after thrust of the body 1, the bulge (or the plate) 11 is positioned in a cylindrical housing 19, the groove 17 no longer holds the arms 5a and 5b horizontal and they can tilt and the handle 6 of the handle 4 is then in its low position.
• the body 1 is actually locked to a location for receiving it, and that the box is placed vertically or horizontally.
• This solution advantageously provides a keying during the establishment of the boxes. Indeed, because of the presence of the bulge (or the wafer), the box can be introduced with the orientation allowing the introduction of the bulge (or the wafer) in the groove 17 or 18 considered.
• FIG. 6a It is also possible, as shown in FIG. 6a, to make a magazine 12 that does not have vertical grooves.
• the crates can be introduced only horizontally.
• the horizontal groove (s) 17 will carry at regular intervals cylindrical housings 19 embodying the locking positions for the crates.
• FIGS 8a and 8b show such a variant in which the end of an arm 5a carries two tabs 20, cut in the same material of the arm 5a, and folded.
• Each tongue 20 thus has a flat portion 20a and substantially parallel to the arm 5a and an inclined portion 20b which connects the flat portion 20a to the arm 5a.
• the tongues 20 are arranged symmetrically with respect to a plane P, perpendicular to the arm 5a, and passing through the hole 21 receiving the axis 8.
• the tongues 20 are thus projecting relative to the arm 5a and form the bulge 11. They have a width 1 substantially equal to that of the grooves 17 and 18 carried by the magazine 12.
• each tongue is also substantially equal to the diameter of the housing 19 in which the groove or grooves 17 and / or 18 opens.
• the tongues 20 are, as in the previous embodiment, guided by the grooves 17 or 18 and they allow by their cooperation with a housing 19 to lock a munition box in a store.
