Definitions

the present invention relates to a bolt locking device for an automatic weapon in which the longitudinal movement of the bolt is caused by a rotary drum driven by an external motor.
Such a weapon is known in particular from document FR-A-2 372 409.
the cylinder head is guided longitudinally and has a roller engaged in a groove of the drum so that the rotation of the latter causes the cylinder head to move back and forth. It is therefore necessary to keep it locked in the closed position when firing the ammunition.
the present invention aims to provide a device for such locking.
the subject of the invention is a bolt locking device for an automatic weapon in which the longitudinal movement of the bolt is caused by a rotary drum driven by an external motor, characterized in that it comprises a wedge of movable locking under the action of a cam driven in rotation in synchronism with the drum, between an erased position which allows the free passage of the cylinder head, and a locking position where cooperating abutment surfaces on the cylinder head and on the wedge lock the cylinder head in the closed position.
the locking corner can in particular be animated by an alternative translational movement between these two positions.
the device according to the invention comprises declutching means for disengaging the cam from the locking corner when the cylinder head is not in the closed position.
declutching means can in particular comprise at least one fork pivotally mounted under the action of the cylinder head, this fork being arranged to cause an axial displacement of the cam.
said fork has on one side of its pivot axis an engagement surface with a roller mounted on the cylinder head and on the other side of its axis, an actuating finger engaging in a groove in the cam.
the device according to the invention may further comprise holding means for holding the cam in the disengaged position, for example a lock controlled by the cylinder head to engage in the aforementioned groove.
This lock can in particular be mounted pivoting about an axis and actuated by two pushers arranged on either side of the axis and cooperating with ramps formed on the cylinder head.
said cam cooperates with two rollers mounted on the locking corner, one of the rollers being able to be mounted on a lever pivoting on the corner to retract this roller and thus block the corner in the locked position in the absence of recoil of the weapon.
Figures 1 and 2 show the rotary drum 1 and its helical groove 2 in which is engaged a roller 3 mounted on the cylinder head 4.
the drum is driven by a motor not shown.
the cylinder head is also provided with guide rollers 5 so that a rotation movement of the drum 1 causes a longitudinal reciprocating movement of the cylinder head.
the locking of the cylinder head in the closed position is obtained by means of a locking wedge 6 having an abutment surface 7 cooperating with an abutment surface 8 of the cylinder head.
a grooved part 9 of the shaft of the rotary drum 1 carries a cam 10 making it possible to give a vertical reciprocating movement to the corner 6.
the cam cooperates with two rollers 11 and 12 carried by axes 13 and 14 respectively mounted on the corner.
Two forks 15 are pivotally mounted on the frame 16 of the weapon and have on one of their sides a surface 17 in the form of a hook to cooperate with a roller 18 of the breech and on their other side a finger 19 engaged in a groove 20 of the cam 10.
a roller 18 of the breech and on their other side a finger 19 engaged in a groove 20 of the cam 10.
the cylinder head 4 arrives in the locking position, its roller 18 engages in the surface 17 and thus rotates the forks 15 which push the cam 10 into a housing 21 in the corner between the rollers 11 and 12, so that the cam and the corner are engaged.
the opening of the cylinder head causes or causes the forks 15 to tilt in the opposite direction, the cam 10 leaving the housing 21 and therefore being disengaged from the corner.
the frame 16 also supports an axis 22 on which is mounted a lever 23 integral with a latch 4 capable of engaging in the groove 20 of the cam 10 to maintain the latter in the disengaged position.
the lever 23 is controlled by two pushers 25 and 26 sliding vertically under the action of ramps 27 and 28 respectively of the cylinder head.
roller is mounted at one end of a lever 29 pivoting on the corner 6 around an axis 30 and carrying at its other end a roller 31.
the lever 29 is held in the position shown in the drawing by the reaction of the roller 31 on a surface 32 of a lever 33 itself mounted to pivot about an axis 34 carried by the frame 16 of the device.
An axially movable rod 35 normally maintains the lever 33 in the position shown in FIGS. 3 and 4, except in the event of a long fire where it allows any lever suitable for the lever 33 to pivot around the axis 34 thus eliminating the support of the roller 31 and retracting the roller 12. In such a case, the wedge 6 is consequently immobilized in the locked position and the cylinder head 4 remains closed.
the roller 18 causes the forks 15 to tilt, which has the effect of moving the cam 10 inside the housing 21 where it engages with the rollers 11 and 12.
the ramp 28 caused the pusher 26 to be pushed in and the pusher 25 to rise so as to release the latch 24 from the groove 20 of the cam 10.
the cam 10 drives the corner 6 downwards, which has the effect of unlocking the breech.
the surface 27 causes the pusher 25 to be pushed in and the pusher 26 to rise as shown in FIG. 4, which has the effect of engaging the latch 24 in the groove 20 of the cam 10, and consequently of block this cam on axis 9.
