Definitions

  • the invention relates to a self-erecting mine with a mine housing which holds the charge of the mine and which has a standing surface, and erecting elements which are attached to the mine housing and which have an articulation region near the base and an end region and which are pretensioned from a first position in which they are in contact with the mine housing are folded up, are pivotable into a second position in which they protrude from the mine housing.
  • Mines often have a preferred direction of action. They must therefore be aligned in order to achieve the desired effect. The need to align the mines is particularly so when the mines are airborne and distributed over a large area.
  • DE 37 33 150 A1 describes a mine with erection elements which are arranged distributed around the stand area.
  • the erection elements are movably attached to the mine housing with a linkage area and lie against the mine housing in the folded state.
  • the erection elements are pretensioned and are held in their folded position by a tether. When the tether is severed, the erection elements spread out and thereby erect the lead.
  • the erection elements are telescopic or foldable, so that they are longer when folded down than when folded.
  • the invention has for its object to provide a self-erecting mine, in which the erecting elements are simple and which functions smoothly even under adverse operating conditions.
  • the mine according to the invention has a mine housing with a base and attached to the mine housing Raising elements.
  • the erecting elements are pivotally mounted on the mine housing under tension from a first to a second position and, in their first folded position, are elastically bent over the mine housing in planes running perpendicular to the standing surface, so that the end region of an erecting element on the side opposite the articulation area of this erecting element of the mine housing.
  • the erecting elements are elastically bent around the mine housing in planes running perpendicular to the standing surface, additional folding elements are not required and the erecting elements nevertheless have a length which is considerably greater than that of known one-part erecting elements, so that the mine comes up when the erecting elements are in the second position has very high stamina. Since the erecting elements do not require any folding elements, the mine works even under adverse operating conditions.
  • the lead housing has a substantially hemispherical upper part which has approximately the same diameter as an im essential cylindrical lower part of the mine housing.
  • the hemispherical upper part allows the lead to roll off the ground until it lies with its cylindrical lower part.
  • the number of erecting elements is odd.
  • the arrangement of an odd number of erection elements with the same distances between the erection elements ensures that the articulation regions and end regions of individual erection elements alternate on the circumference of the lead.
  • the articulation areas are always next to the end areas and the lifting elements can therefore spread apart without interfering with each other.
  • the arrangement of only three erection elements leads to significant cost savings and also means that space is saved in the base area of the mine.
  • the erecting elements are held in the folded state by means of a tether band arranged parallel to the base of the mine housing.
  • the tether is detachable and can e.g. be solved pyrotechnically, so that the outwardly biased erecting elements spread apart and erect the mine.
  • the lead 10 has a lead housing 12 with a hemispherical upper part 14 and a cylindrical lower part 16.
  • the upper and lower parts 14, 16 have approximately the same diameter.
  • the cylindrical lower part 16 has the base 18 of the mine 10 on its lower end face.
  • Each erection element 20 is arranged evenly distributed on the circumference of the mine 10.
  • Each erection element 20 consists of two parallel rod-shaped wires (21a, 21b) which protrude radially from the lead 10, but are in contact with the lead housing 12 in the folded state.
  • the two wires of each erecting element can be connected to one another by webs.
  • the erection elements 20 are brought over the upper part 14 of the mine approximately in the region of the highest point, the erection elements 20 crossing in this region.
  • the erection elements 20 are pivotally mounted on the mine housing 12, each of the two wires 21a, 21b of an erection element 20 being wound into a coil spring 22 (FIGS.
  • each helical spring 22 extends approximately tangentially to the lead housing 12.
  • the region adjoining the helical springs 22 of each erecting element 20 and abutting the lower part of the lead housing 12 is referred to as the articulation region 24.
  • the wires 21a, 21b of the erecting elements 20 follow the contour of the mine housing 12, so that they lie bent over by 180 ° on the side of the mine housing 12 opposite the articulation region 24 with respect to the longitudinal axis 26 of the mine 10.
  • the regions of the erecting element 20, which bear against the lower part 16 of the mine 10 on the side of the mine housing 12 opposite the articulation region 24, are referred to as end regions 28.
  • the wires 21a, 21b of the erecting elements 20 are connected to one another at their free end which is not anchored to the lead 10 or are formed in one piece continuously or not interrupted, ie continuously, and they are profiled in such a way that they rest on the lower part 16 in the folded state Articulation areas 24 have greater flexural rigidity than the areas of the erection elements 20 abutting the upper part 14 surrounds.
  • the lead 10 stands on its standing surface 18.
  • the erecting elements 20 protrude radially from the standing surface of the lead housing 12.
  • the shaped charge funnel 34 of a shaped charge 36 provided as a charge in the mine housing 12 points upwards in this position.
  • An essentially dome-shaped cover cap is placed on the cover 38 of the shaped charge 36, which can be arranged both below the erection elements 20 and above or between the intersecting erection elements 20. In the last and first case there is a connection to the neighboring erection element.
  • the shaped charge hopper 34 is filled with a foam filling 40.
  • a resilient sensor wire 42 for triggering the mine 10 protrudes from the mine 10 substantially perpendicular to the base 18.
  • the mine 10 When used, the mine 10 can be dropped from the air. In order to reduce the falling speed, a parachute is provided as the braking device 45, to which the mine 10 is fastened with suspension lines and eyelets. Since the center of gravity of the lead 10 lies within the lower part 16 of the lead housing 12, the lead 10 rolls into a side position (FIG. 5) after hitting the ground, in which it rests on the peripheral surface of the cylindrical lower part 16. In order to erect the mine 10, the bondage band 30 is unlocked or separated at the joint, for example with the aid of a pyrotechnic charge, and the erecting elements 20 spread apart from the mine housing 12 in accordance with their pretension.
  • the mine 10 is erected, either two end regions 28 with an articulation region 24 or two articulation regions 24 interacting with an end region 28 of the erecting elements 20 and erecting the mine 10.
  • the erecting elements 20 are spread apart, the covering cap with the braking device 45 is also thrown off.
  • the erecting elements 20 have a large length and the mine 10 therefore has a high level of security against lateral tipping over.
