Definitions

  • the invention relates to a mine with an explosive and detonator-containing housing and a cap, in which an actuating element for the detonator and a locking element cooperating with it is arranged, which can be pivoted by means of a focus lever from the locked position into a release position for the actuating element, wherein the sharpening lever has a ring arranged concentrically to the cap axis, with its end faces slidably mounted on the cap, acting on the locking member, the bearing gaps of which are sealed by round cord rings inserted into its end faces.
  • the focus lever should only be able to be moved from the safe position to the focus position with a certain torque. This limit should be such that the sharpening lever does not have to apply excessive torque to the person who is armed to arm the mine.
  • the torque must therefore be on the one hand a certain size, but on the other hand also within a certain tolerance range. These sizes must not change even after long storage.
  • Both the bearing and the seal must also be such that the function and the necessary actuation torque are not impaired or only slightly changed at extreme temperature differences between approx. -30 ° C and + 50 ° C.
  • the seal must ensure tightness against dust and water, possibly also sea water, which in turn requires a certain compression of the seal. However, this pressing must not be too great, since otherwise the torque to be applied to the sharpness lever will be too great.
  • the invention has for its object to improve the previously used cord rings in the sense of the aforementioned requirements.
  • each round cord ring has a circumferential circumferential notch and is inserted so that the notch is open to the side.
  • the notch is preferably designed as a V-groove which, according to a further feature of the invention, is arranged such that the center axis of the round cord ring lies within the groove.
  • the round cord ring which as before is made of a comparatively hard rubber, e.g. B. Perbunan, receives an additional elastic resilience through the notch. In this way, the compression can first be increased and thus the tightness in the area of the bearing of the ring can be improved. Practical tests have shown that absolutely dust and waterproof storage has indeed been achieved with the simplest construction. Furthermore, the pressing can be adjusted without difficulty in such a way that the desired actuation torque for the sharpness lever can be maintained, even in the case of extremely low temperatures, without the tightness suffering as a result.
  • a comparatively hard rubber e.g. B. Perbunan
  • the V-groove starts from the outer apex line of the round cord ring, so it opens to the outside. This not only facilitates the production of the round cord ring, but also has the further advantage that when it occurs a pressure wave, which penetrates into the bearing gap from outside, the O-ring is additionally pressed against the sealing surfaces by widening the V-groove, so the tightness is increased.
  • the mine designated as a whole by 1, has a housing 2 which includes the explosive and a detonator 3. At its center, the housing 2 is closed on the upper side by a cap 4, in which an actuator 5 for the igniter 3 is arranged.
  • the actuator 5 interacts with a partially spherical head 6 of the igniter 3.
  • the detailed structure of the mine is irrelevant in the present context and is otherwise known.
  • the cap 4 can be seen in more detail in FIGS. 2 and 3. It consists essentially of a cyl Indian housing ring 7 and a Deckpl atte 8. Inside the housing ring 7, the actuator 5 is seated under the action of a Spring 9 stands. Locking elements in the form of bolts 10 hold the actuating element in the upper position, the securing, shown in the left part of FIG. 2. The bolts 10, in turn, are fixed in the locked position by a ring 11 acting on the outside thereof, which has a plurality of axially parallel recesses 12, into which the bolts 10 can retract under the action of the spring 9, so that the actuator 5 can be seen in the one shown in FIG. 2 on the right Position that can be brought into focus from which the detonator is actuated when pressure is applied from above.
  • the one-piece sharpness lever 13 engages approximately radially, which can be pivoted from the position shown in solid line in FIG in the right half in FIG. 2.
  • the sharpness lever 13 runs on a de cap on a part of its circumference surrounding resilient support bracket 14 which has a stop ring 15 between the two positions of the sharpness lever 13.
  • the focus lever can only be moved in the direction of the focus if the support bracket is previously pressed down by pressure on the plate 17.
  • the ring 11 is mounted between a collar 17 on the housing ring 7 of the cap 4 and the underside of the cover plate 8 with its end faces.
  • the storage is shown in more detail in Figure 4.
  • the ring 11 has on its two end faces an annular groove 18 into which a round cord ring 19 is inserted, which seals the bearing gap 20 between the cover plate 8 and ring 11 or between the latter and the collar 17.
  • the pressing takes place in such a way that the cover plate 8 is screwed onto the housing ring 7.
  • the round cord ring 19, as can be seen in FIG. 4, is provided with a notch 21 in the form of a V-groove, which is provided on the outer periphery of the round cord ring 19.
  • the groove is inserted so deeply into the round cord ring 19 that its base 22 is located beyond the central axis 23 of the round cord ring 19.
