• the technical field of the invention is that of light weapon systems adaptable to a vehicle hatch.
• Armored vehicles for military use often include a panel of weapons adapted to their main mission.
• a tank that is a vehicle specialized in direct fire or tight fire, it includes a gun for direct anti-tank fire or anti infrastructure.
• This weapon is often associated with a secondary weapon of small or medium caliber intended for the direct fire antipersonnel or anti light material.
• Patent EP0011856 also discloses an armored vehicle turret comprising a weapon support rigidly secured to the turret.
• this weapon support is not a light weapon system that can interface with a manhole.
• Patent FR 2674949 discloses a mortar with rear loading.
• This weapon system is the main armament of the turret and not a secondary armament. he requires specific means (not described by this patent) for loading the mortar through the turret and also to control the pivoting of a projectile bearing liner of this mortar from inside the turret. This system is therefore heavy and complex.
• EP1273869 discloses a vehicle comprising two mortars loaded by the mouth which are served under armor. There it is the whole vehicle that is devoted to feeding each mortar ammunition. This device is therefore also complex, and it can not be associated with a turret without a significant impact on the architecture of the vehicle.

• the invention relates to a light weapon system for firing mortar shells and interfacing on a manhole of a cockpit, weapon system comprising:
• a raiser surrounding the manhole and extending vertically above the manhole, raises closed by a hinged door and having an opening for allowing to feed the mortar tube through his mouth with a shell,
• a support of the mortar tube secured to the socket by a first end and comprising at its second end a pivot connection secured to the mortar tube
• firing means for firing the shell.
• the light weapon system comprises a closure means of the opening ensuring a ballistic protection.

• the chute of the drawer is open in its upper part to let in and out of the drawer the mouth of the tube during positioning movements in site thereof.
• the light weapon system may include a site angle sensor for pointing up the tube.
• the firing means is a striker controllable from inside the vehicle and located in the cylinder head of the tube.
• the tube orientation means of the tube is an electric jack.

• a turret 100 of an armored vehicle (vehicle represented very schematically) comprises two manholes 101 and 102 intended to let in or out all or part of a crew member in a passenger compartment formed by the turret 100.
• Each manhole is closed by an articulated hatch 101a and 102a.
• One of the manholes 101 carries a light weapon system 1 according to the invention, which is intended to fire mortar shells.
• This weapon system 1 comprises a mortar tube 2 which is, according to the embodiment shown, oriented in parallel with the reference to the main weapon 100a of the turret 100.
• the bearing pointing of the weapon system 1 will therefore be carried out by rotating the turret or the entire vehicle.
• the weapon system 1 is fixed at the manhole by conventional fastening means, such as screws and / or bolts, other means may be used.
• the weapon system comprises a riser 3 which extends vertically above the manhole 101a (not visible hole).
• This enhancement 3 surrounds the entire periphery of the manhole.
• a support 4 of the mortar tube 2 is secured in a fixed manner at a first end of the riser 2, below a hinge 5 serving to open the hatch 6.
• the support 4 extending substantially horizontally in a plane of interfacing P of the weapon system 1 on the manhole.
• the support 4 comprises at its second end a pivot connection 4b intended to allow the rotation of the tube 2 around the horizontal axis A to orient the tube 2 in place and thus adjust the rise.
• the support 4 comprises two lateral flanks 4a between which a front portion of the tube 2 having the mouth of the tube 2a can be placed when it is horizontal.
• the weapon system 1 comprises an orientation means 7 of the tube 2 in site.
• the orientation means 7 is an electric jack secured to a flank 4a of the support 4 and secured by another end of the pivot connection 4b connected to the tube 2 (for example by a connecting rod - crank system ).
• the second end of the jack may be integral with the tube 2 directly.
• This cylinder 7 is controllable from the cabin of the turret 100.
• the weapon system 1 comprises a measuring means (not shown) for the orientation of the tube 2.
• a measuring means for the orientation of the tube 2.
• Such means are well known to those skilled in the art, they may be constituted by an angular sensor for example or any other measuring means for indicating the value of pointing in site of the tube to a servant of the weapon system located in the cabin of the turret 100.
• the weapon system 1 is shown without its hatch or hinge to see the internal operation of the weapon system 1.
• the riser 3 has in its wall an opening 8 opening, towards the outside of the extension 3, between the flanks 4a of the support 4 and facing the mouth 2a of the tube 2 when it is at the horizontal.
• This opening 8 corresponds with a loading means 9 of the tube 2.
• This loading means may be a slide 9 which is slidably mounted by a sliding connection 10 in the opening 8, the sliding drawer of the inside of the riser 3 to outside and vice versa.
• the drawer 9 has on one of its sides a window 11 intended to allow to place a shell 12 inside the drawer 9.
• the shell 12 is placed so that its rear part is closest to the opening 8 so that this part subsequently enters the first in the mouth 2a of the tube 2 during the loading of the shell 12 as shown in Figure 4.
• the servant During loading, from the cabin of the turret 100, the servant has access to the drawer while being protected by the hatch 6 which closes the raiser (hatch not shown at Figure 4). It pushes the drawer towards the tube 2a, thus causing the shell 12 to enter the mouth of the tube 2a.
• the drawer 9 has a stretcher shape and therefore has a chute 9a which is sized to let the tube 2 into the drawer 9 when pushing the latter to slide the shell 12 in the mouth 2a of the tube 2.
• the chute 9a of the drawer 9 is also completely open in its upper part. Thus the tube can be rotated for its positioning in the site without being obstructed by the drawer 9.
• the drawer 9 carries at its rear part a plate 9b ( Figure 8) forming a closing means of the bottom of the opening 8.
• This plate 9b provides ballistic protection of the riser 3 once the tube tilted.
• a locking means (not shown) will lock the drawer 9 relative to the riser 3 in this position.
• the plate 9b will be made of a material having resistance capabilities similar to that of the riser 3 and will have a thickness of the same order as that of the riser.
• the drawer 9 is open on its upper part leaving the tube 2 apparent and free to move upwards.
• the operator controls the setting of the desired firing site from inside the turret by activating the jack 7.
• the tube 2 under the action of the orientation means 7, raises the mouth 2a of the tube which causes the descent of the shell at the bottom of the tube 2 by gravity.
• the servant can control the firing of the shell by means conventionally known to those skilled in the art such as a remotely controllable striker located in the cylinder head 2b of the tube 2.
• the weapon system According to a simpler embodiment of the weapon system according to the invention, it is conceivable not to equip the weapon system with a loading drawer. In this case, the shell will be inserted manually into the mouth of the tube through the opening 8.
• a pivoting flap can be provided to close the opening
• the ballistic tightness is not guaranteed in this case during the loading phase.
• the small size of the opening 8 and its position protected by the flanks 4a of the support 4 provides a low exposure of the servant vis-à-vis the ballistic threats.
• the invention makes it possible to equip an armored vehicle with a light weapon system that can be safely served from the passenger compartment of the vehicle without causing the vehicle to be heavily modified.
• pivot connection 4b between the tube 2 and the support 4 is located cantilevered with respect to the turret nape. This allows the tube 2 to point in height without its breech interferes with the turret.
