Definitions

  • Safety devices of this type are known. Attention is drawn in particular to CH-A-531 159 and to US-A-3 985 079, in which a safety device is described which has a rotor which is connected to an escapement which either has a clockwork or by means of a Silicone grease is formed, which slows down the rotation of the rotor.
  • This known device also has a first safety element which responds to the launch acceleration and a second safety element which responds to the swirl. It is disadvantageous that the rotor already begins to turn when the inhibitor is still effective, and that a safety device responds exclusively to the launch acceleration and not additionally to the swirl.
  • a safety device of this type is also known (see DE-B-2 247 209), which also has a rotor which is functionally connected to an inhibitor. The rotor cannot begin to turn until the escapement has run out. Safety devices that respond to launch acceleration or swirl and that serve to release the rotor are not available.
  • a safety device is known (see DE-A-1 927911), which responds to the launch acceleration and the swirl, for releasing the rotor for its rotation into the arming position.
  • This security device is built into a detonator fuse, which, however, has no second security device that responds exclusively to the twist.
  • the object of the present invention is to provide a safety device in which, by means of a suitable combination of the individual elements, all the requirements placed on such a safety device are met as far and as well as possible.
  • this safety device can be assembled before they are installed in the safety device, and that the safety device can be fully assembled before they are installed in the swirl projectile detonator.
  • a known ground igniter has a housing 10 which can be screwed in with its external thread 11 at the rear end of a projectile body, not shown.
  • This housing 10 is closed by a cover 12 which is screwed into an internal thread 13 of the housing 10.
  • An amplifier charge 14 is fastened to this cover 12, which projects into the explosive charge, not shown, inside the projectile body.
  • Under the cover 12 there is a plate 15 to which the electronic elements 16 of the detonator are attached.
  • a rotor 17 with a primer 18 is arranged above the plate 15.
  • a further primer capsule 19 is provided below the rotor 17.
  • a current generator or a current store 20 is provided for igniting this capsule 19.
  • a securing device has a housing 29 which is closed by a cover 29a.
  • a rotor 21 - which corresponds to the rotor 17 shown in FIG. 1 - is rotatably mounted about a vertical axis 22.
  • the rotor 21 contains an ignition capsule 23 and an inertial body 24 in order to shift the center of gravity of the rotor 21 outside the axis of rotation.
  • the rotor 21 has a toothing 25 which interacts with an inhibitor 26 in order to delay rotation of the rotor 21.
  • two securing members 27, 28 are present, which prevent the rotor 21 from rotating prematurely about its own axis 22.
  • the rotor 21 is in focus when the primer is on the projectile axis.
  • the first securing member 27 responds only to the projectile swirl, i. H. this organ releases the rotor 21 as soon as the swirl of the projectile has reached a limit value when the projectile is launched.
  • This organ 27 is therefore referred to as a swirl protection element.
  • the second organ 28 responds only to the floor acceleration, i. H. this member 28 releases the rotor 21 as soon as the projectile's acceleration has reached a limit value. Therefore, this organ 28 is referred to as an acceleration safety device.
  • the first organ 27, i. H. the swirl safety element is described in more detail with reference to FIGS. 4 to 6 and the acceleration safety element is described in more detail with reference to FIGS. 7 to 10.
  • the swirl securing member has a sleeve 30 in which a piston 31 is guided.
  • a spring 32 tends to push the piston 31 in the sleeve 30 to the right according to FIG. 4, it is supported on the one hand on the bottom of the sleeve 30 and on the other hand on 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 located in a bore 33 in the housing 29 (FIG. 3). This bore 3 also has a larger inner diameter than the right end, corresponding to the sleeve at the left end.
  • the bore 3 therefore has a shoulder 34 (Fig. 4-6).
  • the piston 31 has three recesses 35-37, of which the middle recess 35 is the deepest, the right recess 36 is less deep and the left recess 37 is even less deep.
  • the sleeve 30 has a transverse bore 38 which is conical at one end and partially allows a ball 39 through.
  • the ball 39 protrudes from the sleeve 30 and is supported on the shoulder 34 of the bore 33 in the housing 29 when it is in the least deep recess 37 of the piston 31. 5, however, the ball 39 is in the less deep recess 36, then it still protrudes into the bore 38 of the sleeve 30, but not out of the sleeve 30 and therefore no longer bumps against the shoulder 34 However, if the ball 39 is in the deepest recess 35, it no longer protrudes into the bore 38 of the sleeve 30, as a result of which the spring 32 is able to push the piston 31 completely out of the sleeve 30 (not shown). 4, the rotor 21 is missing and the piston 31 can penetrate into the recess 41 of the housing 29 provided for the rotor 21 until the ball 39 abuts the shoulder 34 of the bore 33 of the housing 29.
  • the piston 31 projects into a sack Hole 40 of the rotor 21 into it and, according to FIG. 6, the piston 31 is supported on the incorrectly inserted rotor 21.
  • the acceleration securing element 28 has a cylindrical housing 42 which has a non-continuous eccentric longitudinal bore 43 and an inclined continuous transverse bore 44. At the lower left end of the transverse bore 44 there is a cam 45 which prevents a ball 46 located in the transverse bore 44 from falling out.
  • a piston 47 is arranged displaceably in the non-continuous longitudinal bore 42.
  • a spring 48 tends to push the piston 47 upward.
  • This piston 47 has at its upper end 49 and in the middle 50 the same diameter as the longitudinal bore 43.

  • the transition from the upper piston part 51 to the end 49 and the transition from the lower piston part 52 to the center 50 are also conical.
  • a guide pin 54 for the spring 48 projects downward from the center 50.
  • the center 50 also has a groove 55, which is necessary for assembly.
  • the spring 48 is first pushed into the longitudinal bore 43 until it abuts the bottom of the longitudinal bore 43, and then the ball 46 is rolled into the transverse bore 44 until it abuts the nose 45. Finally, the piston 47 is pushed into the longitudinal bore 43, the groove 55 being in the region of the ball 46, then, when the center 55 of the piston 47 is below the ball 46, the piston 47 is rotated through 180 ° about its longitudinal axis to get it into the position shown. The center 50 of the piston 47 is then supported on the ball 46 and the piston 47 is pressed against the ball 46 by the spring 48. 3, the ball 46 protrudes into a recess 56 in the rotor 21.
  • another embodiment of the securing member 28 has a cylindrical housing 57 which is displaced by a cover 58.
  • this housing 57 there is a mushroom-shaped piston 59 which is pressed against the cover 58 of the housing 57 by a spring 60.
  • the spring 60 is supported on a ring 61 which bears on a shoulder 62 of the housing 57.
  • the housing 57 In the area of this shoulder 62, the housing 57 has a non-continuous transverse bore 63 in which a ball 64 is located.
  • the piston 59 has a spherical thickening 65 at its lower end and a convex neck 66 above it.
  • the thickening 65 of the piston 59 presses the ball 64 against a flanged edge 67 at the outer end of the bore 63 (FIG. 8), as a result of which Ball 64 protrudes from housing 57 and projects into recess 56 of rotor 21 (FIG. 3).
  • the ring 61 has a recess 68 into which the ball 63 partially protrudes, as can be seen in FIG. 9.
  • the ring 61 is conical on the outside, so that it turns against the force of the spring 60, for. B. can tilt under the action of a centrifugal force. 10, the ball 64 can be pressed against the neck 66 of the piston 59, whereby the ball 64 no longer protrudes from the housing 57.
  • a further embodiment of the securing member 28 has a cylindrical housing 69 which is closed by a cover 70.
  • this housing 69 there is a mushroom-shaped piston 71 which is pressed by a spring 72 against the cover 70 of the housing 69.
  • the spring 72 is supported on a sleeve 73 which is rigidly anchored in the housing 69.

  • the housing 69 has a non-continuous transverse bore 75 in which a ball 76 is located.
  • the piston 71 has a spherical thickening 77 at its lower end and a convex neck 78 above it.
  • the thickening 77 of the piston 71 presses the ball 76 against a flanged edge 79 at the outer end of the transverse bore 75 (FIG. 11), as a result of which Ball 76 protrudes from the housing 69 and protrudes into the recess 56 of the rotor 21 (FIG. 3).
  • the ring 74 has a recess 80 into which the ball 76 partially protrudes, as can be seen in FIG. 11.
  • the ring 74 is conical on the outside and can z. B. tilt under the action of centrifugal force. 12, the ball 76 can be pressed against the neck 78 of the piston 71, as a result of which the ball 76 no longer protrudes from the housing 69.
  • 11 and 12 is essentially the same as in the case of the acceleration securing element according to FIGS. 8 to 10. The only difference is that the ring 74 is not inclined against the force of the spring 72 must and can therefore be inclined more easily.
  • the securing device 110 contains a rotor 111 (FIG. 17) which is rotatably mounted about an axis 112.
  • An ignition capsule 113 is fastened in this rotor 111.
  • an oscillating armature 114 is rotatably mounted in the rotor 111, as can be clearly seen in particular from FIG. 17.

  • the gearwheel 116 can rotate one tooth further with each pivoting movement of the oscillating armature 114.
  • the gearwheel 116 is driven by a toothed segment 117 (FIGS. 13, 14 and 15) via a transmission which consists of four gearwheels 118, 119, 120 and 121.
  • Gear 118 is rigidly connected to gear 116.

  • the gear wheel 121 is rotatable about an axis 124 and is in engagement with the toothed segment 117. After the projectile has been fired, the toothed segment 117 rotates under the action of the swirl from the position shown in FIG. 14 to the position shown in FIG 114 is pivoted back and forth.
  • the toothed segment 117 is mounted on the axis 112 independently of the rotor 111. As can be seen from FIGS.
  • the toothed segment 117 abuts the primer 113 when it rotates counterclockwise and tends to also rotate the rotor 111 in the counterclockwise direction.
  • the above-mentioned pin 115 protrudes with its conical head 125 into a bore 126 in the housing 127 (FIG. 13), whereby the rotor 111 is secured against unintentional rotation.
  • This displacement of the pin 115 is caused, on the one hand, by the fact that the twist causes the rotor 111 to strive to rotate clockwise.
  • the head 125 of the bolt 115 is pressed with its conical surface against the edge of the bore 126 of the housing 127, whereby the bolt 115 is pushed upwards into the bore 128 of the segment 117 (FIG. 16).
  • the bullet is decelerated by the air resistance, whereby the bolt 115 has the tendency to move forward anyway, i. H. up in the drawing.
  • the rotor 111 is secured against rotation by two securing members 129 and 130, of which the second securing member 129 responds to the swirl, for releasing the rotor 111 into its armed position and of which the second securing member 130 responds to the launch acceleration and the swirl to release the rotor 111 in its focus.
  • the securing member has a cylindrical housing 131 in which a ball 132 is located in a longitudinal bore and is pressed by a spring 133 against a displaceable and tiltable annular disk 134 , which in turn rests on a plate-shaped cover 135 of the housing.
  • the housing 131 has a transverse bore 136 in the region of the ball 132, in which a second smaller ball 137 is located. At the outer end of the transverse bore 136, a flange 138 is provided, which prevents the second ball 137 from falling out of the transverse bore 136 of the cylindrical housing.
  • the smaller ball 137 can protrude into a recess 139 of the rotor 111 (FIG. 17) and also into a recess 140 of the toothed segment 117 (FIG. 14), whereby according to FIG. 13 at the same time, part of the ball 137 projects into the recess 139 of the rotor 111 and another part of the ball 137 projects into the recess 140 of the toothed segment 117.
  • the spring 133 is compressed by the launch acceleration and by the inertia of the ball 132, whereby the first ball 132 moves downward in the housing 131.
  • the annular disk 134 presses on the ball 137 throughout the entire passage of the pipe and holds it in its locked position.
  • the second ball 137 is pressed against the first ball 132 and against the annular disk 134 by the projectile swirl, as a result of which the ball 137 no longer protrudes into the above-mentioned recesses 139 and 140 of the rotor 111 or of the toothed segment 117.
  • the ball 132 also slides into a lateral recess by means of a swirl effect and remains there.
  • the rotor 111 and the toothed segment 117 are no longer secured against their rotation into the arming position by the securing member 130.

  • a pin 144 of the piston 142 projects into the interior of the spring 143.
  • the sleeve 141 is located in a bore in the housing 127. This bore contains an opening 150.
  • the piston 142 has two recesses 146 and 147, of which the right recess 147 is deeper than the left recess 146.
  • the sleeve 142 has a transverse bore 148, which is slightly conical and contains a ball 149 which partially protrudes through the transverse bore 148. 20, the ball 149 protrudes from the sleeve 141 and into the opening 150 of the housing 127, since it is located in the left, less deep recess 146 of the piston 142. 21, however, if the ball 149 is located in the lower right recess 147 of the piston 142, it still projects into the transverse bore 148 of the sleeve 142, but no longer into the opening 150 of the housing 127. According to FIG. 20 The piston 142 protrudes into a recess 145 in the rotor 111. According to FIG.
  • the piston 142 is supported on the incorrectly inserted rotor 111.

  • the swirl securing element 129 cannot be used either, since when the swirl securing element 129 is inserted into the bore of the housing 127, the ball 149 abuts the edge of the opening 150 and a complete insertion of the sleeve 141 is prevented, as can be seen in FIG. 22. If, however, the rotor 111 has been used as shown in FIG. 20, the swirl securing element 129 can also be fully inserted into the housing.
