Definitions

  • the invention relates to the field of armament, it relates to a light artillery mortar and, more precisely, such a mortar comprising a barrel tube and a bipod to provide three support points on the ground.
  • a conventional artillery mortar is a weapon that generally includes a barrel, an articulated bipod, and pointing and aiming mechanisms.
  • the barrel is articulated on a base plate which can be possibly anchored in the ground and the base of the uprights of the bipod is equipped with points of insertion in the ground.
  • the articulation of the base plate with the barrel tube comprises a ball joint engaged in a ferrule; it constitutes the mortar journaling means, in height and in direction.
  • the pointing mechanisms: screws, nuts and cranks are carried by the bipod which is connected to the barrel-tube by a flexible collar, provided with a clamping means on the tube, by means of a reversing circuit breaker.
  • the recoil force is transmitted to the base plate directly by the breech of the barrel tube; in fact, at the start of the shot, the barrel moves back until its energy is absorbed by the resistance to sinking the ground, then the elasticity of the ground makes it bounce in the opposite direction; in its movements, the tube drives the bipod via the circuit breaker which constitutes a real elastic link between the collar and the bipod.
  • a mortar is a weapon which offers great flexibility of use and whose mechanical design is relatively simple. Pointing of the weapon can be carried out by the corresponding pointing mechanism carried by the bipod; we can significantly enlarge the vertical range by deviating more or less the two uprights of the bipod, by bringing the base plate away from the tips of the uprights of the bipod, by moving the collar along the tube or by pushing more or less deeply the base plate in the ground, which requires only a little earthwork.
  • the invention provides a mortar essentially comprising a barrel tube which slides in a self-locking coupling sleeve secured to a rigid bipod.
  • the bipod is provided with a rolling and sliding means on the ground.
  • FIG. 1 shows, in a perspective view, an artillery mortar according to the invention.
  • This mortar essentially comprises a barrel tube 1 and a rigid bipod 2 mechanically secured to a lockable coupling sleeve 3, in which the barrel tube can be moved longitudinally and rotate around its axis; moreover, this coupling sleeve comprises a control member 4 allowing its unlocking during the aiming operation of the weapon, this control member being directly accessible by the servant of the weapon.
  • the angle A between the long axis tudinal of the barrel-tube and the plane of the rigid bipod has a constant and predetermined value.
  • the barrel-tube is articulated on its base plate 5, in direction and in height, by an articulation means of the ball-joint / ferrule type 6.
  • each of the uprights 7 of the bipod is in the form of a stick to provide a means rolling and sliding on the ground of this bipod, the sticks 8 bearing on the ground by their convex part.
  • the bipod can thus cooperate with its coupling sleeve to the tube to allow pointing angles in height connecting between 45 and 75 °.
  • each of the uprights 7 of the bipod has a folding means 9 thereof against the barrel.
  • the pointing angle in elevation of the mortar is determined by: the length of the feet, the angle A between the axis of the barrel tube and the plane of the bipod and the position of the coupling sleeve along the barrel tube; this position can be varied by the sliding of the coupling sleeve when the latter is unlocked by pressing on the control member 4.
  • the device for locking the sleeve on the barrel will be described later in detail; it suffices to indicate here that this locking device also constitutes a circuit breaker which provides an elastic link between the tube and the bipod.
  • the device for optical pointing of the weapon which is not part of the invention will not be described here; it suffices to note that this optical device can, preferably, be fixed simply in the vicinity of the mouth of the barrel tube.
  • the coupling sleeve 3, locked in position on the barrel tube, does not prohibit the rotation of the latter around its longitudinal axis, this characteristic can be exploited to ensure the tilt correction of the pointing device.
  • the value of the angle A between the axis of the barrel and the plane of the bipod can be around 45 degrees, this weapon being more particularly intended for the curved shooting of conventional projectiles.
  • FIG. 2 shows, in a partial view, the lockable coupling sleeve 3 coupled to the uprights 7 of the bipod.
  • the front part of the uprights is fixed to the coupling sleeve by a set of welds such as 7a and the angle B of the axes of these uprights is determined by the condition of the ground stability of the weapon.
  • FIG 3 shows, in a sectional view a-a of Figure 2, an embodiment of the coupling sleeve and its locking device.
  • This coupling sleeve 3 comprises three elements: a central ring 10c and two added ends 10a and 10b which are fixed to this central ring by a set of screws such as the screws II. These tips and the central ring cooperate to provide two annular grooves 12a and 12b in which are placed two rings 13a and I3c, these rings being kept inclined at an angle ⁇ , in an elastic manner, in their corresponding grooves.
  • the inclination of the rings is obtained by elastic sliding fingers 14a and 14b, arranged in the wall of the end pieces 10a and 10b, opposite the rings which come to bear on a set of pins 15a and 15b.
  • the function of these pins, arranged in the annular grooves, is to apply the part of the ring diametrically opposite the sliding finger on the wall of the annular groove.
  • the wall of the central ring 10c is provided with fingers 16a and 16b which can slide freely therein; these movable fingers being arranged opposite the elastic sliding fingers 14a and 14b.
  • the central ring is also provided with a support 17 for a push button 4 which has a cylindro-conical base 4a.
  • the connection between the cylindrical-conical part of the push button and the movable fingers 16a and 16b is ensured by cylindrical parts 18a and 18b which slide freely in housings such as 19b.
  • the internal diameter of the rings 12a and 12b is very slightly greater than the diameter of the barrel tube to ensure the free sliding of the coupling sleeve when the value of the angle of inclination of the ring is reduced to a value substantially zero by the action of the push button.
  • the rings, the function of which is to wedge the barrel tube in the coupling sleeve to the bipod are, preferably, made of a material such as a treated steel. The section of these rings is determined to obtain an effective jamming of the barrel tube, it depends in particular on the diameter of this barrel tube.
  • the width of the annular grooves is determined by the value of the angle of inclination 0 ⁇ necessary to obtain the jamming of the barrel tube, this small value, is between 4 ° and 8 °.
  • FIG. 3 also shows an embodiment of the articulation of the upright of the feet making it possible to fold the latter against the barrel tube.
  • the part of the upright 7 welded to the coupling sleeve is lined by an element 20 which fits into a corresponding part located on the part of the upright extended by its butt.
  • the articulation is ensured by a pin 21 held in position by screws 22a and 22b bearing on spacer washers 23a and 23b.
  • a sliding knurled ring 24 locks the joint in the firing position, this knurled ring being held in position by an elastic lock consisting of a spherical element 25 and a helical spring 26.
  • Figure 4 shows, in exploded view, the elements constituting the articulation of the uprights of the feet.
  • the feet can be folded against the barrel to facilitate the transport and storage of the weapon.
  • the shape of the bipod sticks and the shape of the base plate of the barrel can be adapted to obtain an extremely compact weapon in the transport and storage position.
  • the aiming in height of the barrel tube is facilitated by the introduction of a self-locking device integrated in the coupling sleeve of the bipod; at the start of the blow, the risks of mechanical rupture of the bipod are eliminated by the disjunction effect provided by the self-locking device; the weight of the mortar can be significantly reduced, less than 10 kgs.
