Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a safety device for a whirling projectile comprising an auxiliary charge and a fuse. This safety device consists of (a) a rotor which is moved from a safe position to a loading position during firing of a bullet and whose axis is supported outwardly of the axis of rotation of the bullet; and (b) a rotor which is moved after firing of a bullet. a braking mechanism for releasing the rotor to the loading position; (c) a first safety member responsive to firing acceleration and rotation for releasing the rotor and rotating the rotor to the loading position; and (d) releasing the rotor and rotating the rotor to the loading position. and a second safety member responsive to swirl of the bullet for rotation.

The fuse safety device has the following requirements.

The interruption of the ignition system in the fuse must be configured in such a way that the first part of the ignition system is separated from the conveying charge and the auxiliary explosive by at least one blocking device or safety device until the safety device is released. The safety device must be directly mechanically lockable by at least two safety elements that operate independently of each other. Each safety device must be actuated by at least one environmentally constrained force that does not act on other safety devices.
In order to ensure that the ignition system is not interrupted in the event of a failure of the safety or blocking device, the fuse is designed in such a way that it cannot be assembled without a blocking element.

Many safety devices of this type are known. In particular, mention may be made of the one described in Swiss patent specification 531159, which has a rotor which is operatively connected to a special drive mechanism. However, this known device has the disadvantage that the rotor has already started rotating when the braking mechanism starts moving. This known device further includes a safety device responsive to launch acceleration. However, this known safety element has the disadvantage that it responds exclusively to launch acceleration, but not to turning.

Furthermore, safety devices of this type are known which likewise have a rotor, which rotor is operatively connected to a braking mechanism. (West German Patent Application Publication
2247209). The rotor can only start rotating once the braking mechanism has finished operating. However, a disadvantage of this known device is that the braking mechanism has an oscillating pallet whose oscillating axis lies outside the pivot axis of the projectile. As a result, reliable functioning of the braking mechanism is not guaranteed.

The object of the invention is to provide a safety device which, by means of a suitable combination of individual elements, fulfills as far as possible all the requirements placed on such a safety device.

A safety device that solves the above problems is a structural unit in which a safety device consisting of a rotor, a braking mechanism, and first and second safety members is present in a housing, and can be disposed between the auxiliary explosive of a swirling bullet and the fuse. The first and second safety elements are likewise provided in a respective housing and are each specified by being incorporated into the housing of the safety device as a separate unit.

The advantage of this safety device is that the safety element can be assembled before its incorporation into the safety device and that the safety device can be assembled before its incorporation into the orbiting projectile.

Embodiments of the present invention will be described in detail based on the drawings.

In FIG. 1, a known receiving tube is shown in a housing 1
0, and the housing has its male threaded portion 1
1 can also be screwed into the rear end of the bullet (not shown). This housing 10 is closed by a lid 12 which is screwed into an internal thread 13 of the housing 10. An auxiliary explosive 14 is fixed to this lid 12, and the auxiliary explosive 14 projects into an explosive charge (not shown) inside the shell. Below the lid 12 there is a plate 15 on which the electronic elements 16 of the fuse are fixed. Furthermore, a rotor 17 with a detonator 18 is arranged above the plate 15. Below the rotor 17 is another detonator 19 . For igniting this detonator 19 there is a generator or capacitor 20 .

The construction and mode of operation of the landing tube according to FIG. 1 is not new, and the fuze is shown only to make clear the position in the fuze occupied by the rotor 17 formed according to the invention. .

In FIGS. 2 and 3 the safety device according to the invention has a housing 29 which is closed by a lid 29a. Inside the housing 29 a rotor 21 - which corresponds to the rotor 17 shown in FIG. 1 - is mounted rotatably about a vertical axis 22 . The rotor 21 has a detonator 23 and an inertial body 24 to move the center of gravity of the rotor 21 to the outside of the rotation axis. The rotor 21 has teeth 25 that cooperate with a braking mechanism 26 to delay rotation of the rotor 21. There are also two safety members 21, 28, which prevent premature rotation of the rotor 21 about its own axis 22. The rotor 21 is in the loading position when the detonator is on the bullet axis. During firing, the first safety element 27 only responds to the bullet rotation, ie it releases the rotor 21 as soon as the rotation of the bullet reaches a limit value. This element 27 is therefore designated as a pivot safety element. The second member 28 is simply referred to as the bullet accelerator. That is, when the bullet is fired, as soon as the acceleration of the bullet reaches a critical value, this member 28
releases the rotor 21. This member 28 is therefore designated as an acceleration safety member. The first member 27, the swing safety member, is described in detail on the basis of FIGS. 4-6, and the acceleration safety member is described in FIGS. 7-10.
It is described in detail based on the diagram.

In FIGS. 4-6, the pivoting safety member 27 has a sleeve 30 within which a piston 31 is slidable. A spring 32 tends to move the piston 31 within the sleeve 30 to the right in FIG. 4, and is supported on the one hand at the bottom of the sleeve 30 and on the other hand at the end face of the piston 31. The left end of the sleeve 30 has a larger outer diameter than the right end. The sleeve 30 is connected to the housing 29
(Fig. 4). This hole 33 likewise has a larger inner diameter at its left end than at its right end, corresponding to the sleeve. The bore 33 therefore has a shoulder 34 (FIGS. 4 to 6). The piston 31 has three recesses 3
5, 36, and 37, the central recess 35 is the deepest, the right recess 36 is shallower, and the left recess 37 is even shallower. The sleeve 30 has a transverse hole 3 with a conical end partially passing through the ball 39.
It has 8.

In FIG. 4, when the ball 39 is in the shallowest recess 37 of the piston 31, the ball 39 protrudes from the sleeve 30 and is supported by the shoulder 34 of the bore 33 in the housing 29. However, if the ball 39 is in the medium depth recess 36 in FIG.
0, but does not protrude from the sleeve 30 and therefore no longer abuts against the shoulder 34. When the ball 39 is in the deepest recess 35, it no longer enters the bore 38 of the sleeve 30 and the spring 32 is therefore in a position to push the piston 31 completely out of the sleeve 30 (not shown). In FIG. 4, the rotor 21 is not present, and the piston 31 is replaced by the ball 3 during assembly.
housing 29 provided for rotor 21 until 9 abuts shoulder 34 of bore 33 of housing 29
can be pushed into the recess 41 of.

In FIG. 5 the piston 31 has entered the bottomed hole 40 of the rotor 21, and in FIG. 6 the piston 31 is supported on the misused rotor 21.

The operation mode of this turning safety member is as follows.

When the rotor 21 was assembled, the housing 29
If it is not installed inside, the swing safety member 27 is also not installed. The reason for this is that when the safety member 27 is inserted into the hole 33 of the housing 29, the ball 39 hits the shoulder 34, and as is clear from FIG.
This is because complete insertion of is prevented. However, when the rotor 21 is correctly installed as shown in FIG.
installed inside. The housing 29 of the rotor 21 is then also mounted into the fuze housing 10.

However, if the rotor 21 is installed in the housing 29 in an incorrect position, the safety member 27 will not be installed normally. Because in that case spring 3
2 must be compressed more strongly than usual, as is clear from FIG.

During firing of the bullet, the pivoting of the piston 31 causes it to slide to the left (FIG. 5, ball 39 allows this) so that it no longer protrudes into the bottomed hole 40, thereby causing the rotor to 21 can freely rotate in a manner known per se until reaching its loading position.

In FIG. 7, the acceleration safety element 28 has a cylindrical housing 42, which has a solid eccentric longitudinal bore 43 and an inclined transverse bore 44. A protrusion 45 is present at the lower left end of the transverse hole 44, and this protrusion prevents the ball 46 in the transverse hole 44 from engaging and disengaging. A piston 47 is slidably disposed in the vertical hole 43 that does not pass through. Spring 4
8 urges the piston 47 to push it upward. This piston 47 has its upper end 49 and central 5
0, it has the same diameter as the vertical hole 43. Between the upper end 49 and the center 50 of the piston 47 there are two piston parts 51 and 52 (different in diameter), which are connected to each other by a conical piston part 53. .
the transition from the upper piston part 51 to the end 49;
The transition from the lower piston part 52 to the middle 50 is likewise conical. A guide pin 54 for the spring 48 projects downwardly from the center 50. The center 50 has a groove 55 necessary for assembly.

To assemble this acceleration safety member, first the spring 48 is
The ball 46 is inserted into the vertical hole 43 until it abuts against the bottom of the vertical hole 42, and then the ball 46 is pushed into the horizontal hole 44 until it abuts against the protrusion 45. Finally piston 47
enters the longitudinal bore 43, the groove 55 being in the area of the ball 46, and then when the center 50 of the piston 47 reaches below the ball 46, the piston 47 moves around its longitudinal axis by 180°. , so that the piston reaches the position shown (FIG. 7). The center 50 of the piston 47 is then supported on the ball 46, and the piston 47 is supported by the spring 48 on the ball 46.
6. This ball 46 engages in a recess 56 of the rotor 21 (FIG. 3).

The mode of operation of the described acceleration safety member 28 is as follows.

Firing acceleration causes piston 47 to move against the force of spring 48 in FIG.
is slid downward until it is within the range of the ball 46, and at the same time the ball 46 is located in the inclined hole 44 and is pressed towards the rotor 21. Due to the bullet swirl, the ball 46 is pressed against the piston part 51 and the housing 4 is no longer
It will not stand out from 2. As long as the ball 46 is in the position shown in FIG.
As soon as it is pressed against the piston part 51, the ball releases the rotor 21 and the rotor is pivoted into its loading position.

8-10, another embodiment of the safety member 28 has a cylindrical housing 57, which is closed by a lid 58. In FIGS. Inside this housing 57 is a mushroom-shaped piston 59 which is pressed by a spring 60 towards the lid 58 of the housing 57. The spring 60 has a ring 6 abutting against a shoulder 62 of the housing 57.
1. In the area of this shoulder 62, the housing 57 has an impenetrable transverse hole 63 in which a ball 64 is located. The piston 59 has a spherical bulge 65 at its lower end and a convex neck 66 above it. The ball 64 is formed by the expanded diameter portion 65 of the piston 59.
is pressed against the outer end of the hole 63 towards the flange edge 67 (FIG. 8), so that the ball 64 projects from the housing 57 and engages in the recess 56 of the rotor 21 (FIG. 3). As can be seen in FIG. 9, the ring 61 has a recess 68 in which the ball 64 partially fits. The ring 61 is designed in the form of an outer cone, so that it is inclined against the force of the spring 60, for example under the action of centrifugal force (FIG. 10). In the tilted position of the ring 61, the balls 64 are pressed against the neck 66 of the piston 59 (FIG. 10), so that the balls 64 no longer protrude from the housing 57.

The mode of action of the acceleration safety member according to FIGS. 8 to 10 is as follows.

During firing of a bullet with a landing tube provided with the acceleration safety element 28 described, the piston 59 is pressed downward against the force of the spring 60 under the action of firing acceleration, i.e. into the position according to FIG. . The spring 60 then presses the ring 61 towards the ball 64. As soon as the swivel exceeds the limit value, the ball 64 is pressed against the force of the spring 60 towards the neck 66 of the piston 59 and therefore no longer engages in the recess 56 of the rotor 21, so that the rotor is in the loading position. can be rotated to

11 and 12, another embodiment of the safety member 28 has a cylindrical housing 69, which is closed by a lid 70. In FIGS. In this housing 69 there is a mushroom-shaped piston 71, which is pressed by a spring 72 towards the lid 70 of the housing 69. Spring 72 is supported on sleeve 73 which is engaged with housing 69. A ring 74 is located below the sleeve 73.
is in housing 69. In the area of this ring 74, the housing 69 has a solid transverse hole 75 with a ball 76 inside. piston 7
1 has a spherical bulge 77 at its lower end and a convex neck 78 above it. The bulb 76 is pressed against the outer end of the transverse hole 75 toward the flange edge 79 by the enlarged diameter portion 77 of the piston 71 (FIG. 11), so that the bulb 76 protrudes from the housing 69 and the rotor 21 (third It engages in the recess 56 shown in the figure. ring 7
4 has a recess 80 in which the ball 76 is partially inserted, as is clear from FIG. ring 7
4 is formed into an outer conical shape, and can be positioned diagonally by the action of centrifugal force, for example. ring 74
In the tilted position, the ball 76 is pressed against the neck 78 of the piston 71 (FIG. 12), so that the ball 76 no longer projects from the housing 69.

Acceleration safety member 28 according to FIGS. 11 and 12
The mode of action is essentially the same as that of the acceleration safety element according to FIGS. 8-10. The only difference is that the ring 74 will be positioned diagonally without resisting the force of the spring 72 and can therefore be easily positioned diagonally.

The second embodiment of the safety device in FIGS. 13 to 15 is the fuse housing 1 of the incoming and outgoing tube (FIG. 1).
It has a cylindrical housing 81 with an external thread 82 that can be screwed into the housing. The housing 81 has a first hole 81 coaxially disposed with respect to the fuze axis and provided with a solid hole 84 having an internal thread 84, in which the auxiliary explosive charge shown in FIG. 1
4 can be screwed. Furthermore, the housing 81 has a second solid bore 85 disposed transversely to the fuse axis, in which a cylindrical rotor 86 resides. The rotor 86 is rotatably and slidably disposed in the hole 85 of the housing 81 . The rotor 86 has a detonator 87 and has on its cylindrical surface a helical groove 88 in which a pin 89 engages (FIGS. 1 and 15). This pin 89 cooperates with the groove 88 and is located in the thirteenth position of the rotor 86.
When sliding to the left in the figure, the rotor 86 is rotated by 90 DEG about its own axis. At this time, the detonator 87 reaches below the hole 83, and the axis of the detonator 87
It is located coaxially with respect to the axis of 3. An inertial body 90 inside the rotor 86 acts so that the rotor 86 slides to the left in FIG. 13 due to a turning force when a bullet is fired. Hole 85 and hole 83 in Figure 13
The wall between the detonator 87 and the auxiliary explosive 14 in the hole 83
Thin enough to ignite.

The housing 81 has a third non-through hole 91
, the hole 91 is arranged parallel to the hole 83 (FIG. 15), and in the hole 91 there is an acceleration safety member 92 corresponding to the member 28 in FIGS. 7, 8 or 11. There is. This acceleration safety member 92
has a ball 93 (corresponding to ball 46 in FIG. 7 or ball 64 in FIG. 8 or ball 76 in FIG. 11). The ball 93 enters the recess 94 of the rotor 86 (first
4 and 15) to prevent premature sliding of the rotor as described. The leaf spring 95 in FIG. 14 is a safety member 92.
Do not rotate the ring spring 9 in Fig. 15.
6 prevents the safety member 92 from sliding.

The mode of action of the safety device according to FIGS. 13 to 15 is as follows.

When firing a bullet, the acceleration safety member 92 is
10 and 11-12, by firing acceleration. The rotation of the bullet causes the rotor 86 to slide to the left in FIG.
9 and the spiral groove 88 by 90°. The detonator 87 then reaches its loading position as explained and can be ignited by the electronic element 16 shown in FIG. 1, thereby igniting the auxiliary explosive charge 14 of FIG. In FIGS. 16-20, safety device 110 has a rotor 111 (FIG. 5) rotatably supported about an axis 112. In FIGS.
A detonator 113 is fixed to this rotor 111. Furthermore, as is clear from FIG. 20, a vibrating pallet 114 is rotatably supported on the rotor 111. This vibrating ankle 114 is connected to the pin 11
5, the pin 115 is slidably disposed in the rotor 111, and the pin 115 is slidably disposed in the rotor 111.
In FIG. 6, it is at its lowest position, and in FIG. 19, it is at its lowest position. In the safe position of the rotor 111, pin 1 is
The axis of 5 coincides with the pivot axis of the bullet.

A vibrating pallet 114, which is pivotable about a pin 115, cooperates with a gear wheel 116. In a manner known per se, with each pivoting movement of the oscillating pallet 114 the gear wheel 116 can again be rotated by one tooth.
The gear 116 is connected to the segment gear 117 (16th, 1st
7 and 18), the four gears 118, 119,
It is driven via a gear train consisting of 120 and 121. Gear 118 is rigidly connected to gear 116. Both gears 116 and 118 are rotatably supported about an axis 122. Gear wheels 119 and 120 are likewise rigidly connected to one another and are rotatably mounted around an axis 123, with gear wheel 119 and gear wheel 118 on the one hand;
On the other hand, gear 120 meshes with gear 121. Gear 121 is rotatable about axis 124 and meshes with segment gear 117 .
After firing the bullet, the segment gear 117 is rotated from the position in FIG. 17 to the position in FIG. As a result, the vibrating pallet 114 is oscillated. The segment gear 117 is connected to the shaft 112 independently of the rotor 111.
supported on top. As is clear from FIGS. 18 and 16, the segment gear 117 hits the detonator 113 when rotating counterclockwise, and at the same time attempts to rotate the rotor 111 counterclockwise.
The pin 115 has its conical head 125 projecting into the hole 126 of the housing 127 (16th
), thereby protecting the rotor 111 from unexpected rotation. Segment gear 117 is the 18th
As soon as the position shown is reached, the hole 128 in the segment gear 117 is located above the pin 115, so that the pin is inserted upwardly into this hole 128 in FIG. The sliding movement of the pin 115 is realized, on the one hand, by the rotation of the rotor 111 in a clockwise direction. The head 125 of the pin 115 is then pressed with its conical surface against the edge of the bore 126 of the housing 127, so that the pin 115 is inserted upwards into the bore 128 of the segment 117 (FIG. 19). On the other hand, the bullet slows down due to air resistance and the pin 115
immediately tries to move forward, that is, upward in the figure.

The rotor 111 has two safety members 12 before launching.
9 and 130, the first safety member 129 is responsive to pivoting for release of the rotor 111 to the loading position, and the second safety member 13
0 responds to firing acceleration and pivoting for release of rotor 111 to its loading position.

The structure of the second safety member 130 is clear from FIGS. 21 and 22. In FIGS. 21 and 22, the safety member has a cylindrical housing 131 with a ball 132 in an elongated hole;
The spring 133 causes the dish-shaped lid 135 of the housing to
It is pressed towards a slidable and tiltable ring-shaped disc 134 which rests on the ring-shaped disc 134 . Housing 13
1 has a transverse hole 136 within the sphere 132, in which a second smaller sphere 137 is located. Side hole 1
The outer end of 36 is provided with a flange 138 which prevents the second ball 137 from being able to engage and disengage from the lateral hole 136 of the cylindrical housing. As is clear from FIGS. 17, 18 and 20, the small balls 137 are located in the recess 139 of the rotor 111 (FIG. 20) and in the recess 14 of the segment gear 117.
0 (FIG. 17), at the same time part of the ball 137 in FIG. It's involved. In Fig. 22, the launch acceleration and the ball 132
The inertia of compresses spring 133, thereby causing first ball 132 to move downward within housing 131. At the same time, the ring-shaped disc 134, due to its mass inertia, presses against the ball 137 during passage through the gun barrel and fixes it in the blocking position. At the end of the gun barrel, the second ball 137 is attached to the first ball 132 due to the bullet rotation.
and towards the ring disk 134, so that the balls 137 no longer fit into the recesses 139 and 140 of the description of the rotor 111 or the segment gear 117. Similarly, the pivoting action causes the ball 132 to slide into the lateral recess and remain there. As a result, the rotor 111 and the segment gear 117 are no longer prevented from pivoting into the loading position by the safety element 130.

In FIGS. 23 to 25, the swing safety member 12
9 has a sleeve 141 within which a piston 142 is slidable. Spring 143 urges piston 142 to move to the right in FIG. 23 within sleeve 141. The spring 143 is supported on the one hand on the bottom of the sleeve 141 and on the other hand on the end face of the piston 142. Piston 14
The second shaft neck 144 projects inside the spring 143.
Sleeve 141 resides in a hole in housing 127. This hole has an opening 150. Piston 14
2 has two recesses 146 and 147, the right recess 147 being deeper than the left recess 146. The sleeve 142 has a slightly conical shape and partially extends through the transverse hole 1.
It has a transverse hole 148 containing a ball 149 pierced by a hole 148 . In FIG. 23, the ball 149 protrudes from the sleeve 141 and the housing 12
7 is inserted into the opening 150 of No. 7. The reason is that the ball is located in a medium-depth recess 146 on the left side of the piston 142.
Because it is inside. However, the ball 149 is located in the deep recess 147 on the right side of the piston 142 in FIG.
, the ball is always in the side hole 148 of the sleeve 142.
Although it is inserted therein, it no longer protrudes into the opening 150 of the housing 127. In FIG. 23, the piston 142 is inserted into the recess 145 of the rotor 111. In FIG. 24, piston 142 is supported on rotor 111 which has been incorrectly installed. 25th
The rotor 111 is not shown in the figure, and the piston is assembled so that the ball 149 is inserted into the opening 150 of the housing 127.
can enter the space provided for the rotor 111 until it abuts the edge of the rotor 111.

If the rotor 111 is inadvertently not installed into the housing 127 during assembly of the entire safety installation, the swing safety device 129 will also not be installed. This is because, when inserting the pivoting safety member 129 into the hole in the housing 127, the ball 149 abuts the edge of the opening 150 and prevents the sleeve 141 from being completely inserted, as is clear from FIG. However, according to FIG. 23, when the rotor 111 is installed, the swing safety member 129 is completely installed within the housing. However, if the rotor 111 is incorrectly installed in the housing 127, the swing safety member 129 cannot be installed normally. This is because the spring 143 then has to be compressed more strongly than usual, as shown in FIG. This fault condition is visible from the outside and can be measured, ie from the condition of the shaft head 144. 23 and 24, the pivoting of the piston 142 causes it to slide to the left to such an extent that it no longer engages in the recess 145 of the rotor 111, thereby causing the rotor 111 to can be freely rotated until reaching its loading position.
