Med 1 betecknas ett sakringshus, i vars ovre del en sprangkapselhallare 2, som innehaller en sprangkapsel 3 ar ingangad. Med 4 betecknas en gangning for sakringshusets anslutning till projektilens tandr8r, som kan vara av vilken som heist lamplig i och for sig kand konstruktion. I husets 1 undersida ar anordnat ett diametralt spar 5, vilket nedtill -Lac-ices av en skiva 6, som bildar sparets botten. I sparet ar langdforskjutbart styrd en sakrin.gsslid 7. Skivan 6 vilar mot en skuldra i en hylsa 8, som innehaller detonatorladdning en 9. Detonatorhylsan ar medelst en gang-fling 10 fast vid sakringshuset 1. Kring den slidsparet innehallande cylindriska delen av sakringshuset ãr anordnad en ringformig stalfjader 11, vars fria andar 12 inga i ett sidospar 13 i huset. Delarna 1 och 8 Oro lampligen framstallda av lattmetall, t. ex. en aluminiumlegering. Delarna 6 och 7 kunna t. ex. utforas av stal eller jam.

Arranged in the underside of the housing 1 is a diametrical groove 5, which at the bottom -Lac-ices of a disc 6, which forms the bottom of the groove. In the recess a longitudinally displaceable guide is provided by a locking slide 7. The disc 6 rests against a shoulder in a sleeve 8, which contains a detonator charge. arranged an annular steel spring 11, the free spirits 12 of which are not in a side groove 13 in the housing. Parts 1 and 8 Concerns suitably made of light metal, e.g. an aluminum alloy. Parts 6 and 7 can e.g. performed by stal or jam.

I huset 1 Or pa vanligt satt anordnad en sprangamnesfylld central kanal 14, som fOr att astadkomma detonering av laddningen 9 skall kommunicera med denna via endera av de i sliden 7 anordnade genomgaende fOrbindelsekanalerna eller eldhalen 15, som aven kunna vara fyllda med sprangmedel. Haien 15 aro anordnade pa var sin sida cm slidens 7 tyngdpunktsaxel. I det pa ritningen visade sakringslaget tacker sliden 7 kanalen 14 och halen 15 befinna sig pa ett avstand fran cent-rum, som är ungefar lika med avstandet frail slidens andar till den sparets 5 andar tackande ringen 11. Sliden Mlles normalt i sparrat lage medelst tva pa var sin sida av sliden verkande sparrorgan, vid det visade exemplet kulor 16, 17, som Oro anordnade i radiella borrningar 18 och paverkade av mot ringen 11 stodande fjadrar 19, som trycka kulorna in i sidospar 20 i sliden. Borrningarna 18 Aro riktade snett mot slidens forskjutningsriktning och forlagda pa samma diameter. Kulorna ligga med mindre an halva omkretsen inne i sparen. Sparen ha vid ena sidan, namligen den, mot vilken borrningarna lutar snedvinkel, en rak anliggningsyta 21 fOr kulan, som lutar svagt mot borrningarnas mittaxel. Denna lutning, som Or mellan 0° och 20°, lampligen Indian 2° och 10°, t. ex. c:a 5°, ar till fen- att med sakerhet i alla lagen hindra fastkilning av kulan mellan sparet och borrningens motsatta sida. In the housing 1 or in the usual way arranged a gap channel-filled central channel 14, which in order to effect detonation of the charge 9 must communicate with it via either of the continuous connecting channels arranged in the slide 7 or the firebox 15, which can also be filled with jump means. The shark 15 are arranged on each side of the slide's 7 center of gravity axis. In the securing layer shown in the drawing, the slide 7 tackles the channel 14 and the tail 15 is at a distance from the center which is approximately equal to the distance from the spirit of the slide to the spirit 5 of the spar 5. The slide is normally measured in the sparred layer by two on each side of the slide actuating means, in the example shown balls 16, 17, which Oro arranged in radial bores 18 and impacted by springs 19 standing against the ring 11, which push the balls into side grooves 20 in the slide. The bores 18 are directed obliquely to the direction of displacement of the slide and located at the same diameter. The balls lie with less than half the circumference inside the spade. The spares have on one side, namely the one against which the bores are inclined at an oblique angle, a straight abutment surface 21 for the ball, which slopes slightly towards the central axis of the bores. This slope, as Or between 0 ° and 20 °, suitably Indian 2 ° and 10 °, e.g. about 5 °, is to fen- to with certainty in all laws prevent wedging of the ball between the groove and the opposite side of the bore.

Genom anordningen av borrningarna 18 och kulorna fa de pa var sin sida av sliden verkande sparrkropparna stor sparrverkan pa sli- 2—— den i var sin riktning, varigenom sparrningen av sliden blir synnerligen effektiv i respektive riktning. By means of the arrangement of the bores 18 and the balls, the ratchet bodies acting on each side of the slide have a large ratchet effect on the slide in each direction, whereby the sparging of the slide becomes extremely effective in each direction.

Sakringsanordningen verkar pa foljande satt. I normallaget, sakringslaget, hindra sparrkropparna 16, 17 varje oavsiktlig langdforskjutning av sliden 7 ur sakringslaget. En stot mot ena sidan av projektilen kan mojligen astadkomma forskjutning av den ena sparrkroppen ur sparrlaget genom att kulan komprimerar fjadern 18, men den andra kuIan sakrar da alltid sliden mot f8rskjutning "lid avskjutning av projektilen forskjutes sliden daremot alltid till armeringslaget med endera halet 15 belaget mitt for kanalen 14. Detta beror av att kulorna 16, 17 vid projektilens rotation av centrifugalkraften f5rskjutas ur sparringreppet under hoptryckning av fjadrarna 19. Sliden 7, som har relativt stor tyngd, är aldrig exakt viktcentrerad, utan far alltid genom centrifugalkraften en tendens att forskjuta sig at ena eller andra anden av sparet 5. Forskjutningen av sliden i sparet 5 fiirliindras inom eldroret pa grund av projektilens langdacceleration, som medlar att sliden med stor kraft pressas emot sparets botten 6 och av friktionen mot derma kvarhalles i sparrlaget. Forst nar projektilen overgar till retardationsforloppet, dvs. lamnat eldroret, overvinner centrifugalkraften pa sliden friktionsmotstandet, sO. att sliden forskjutes till armeringslaget. Da befinner sig projektilen pa betryggande avstand. Iran avfyringsplatsen. The securing device operates in the following manner. In the normal layer, the securing layer, the ratchet bodies 16, 17 prevent any unintentional longitudinal displacement of the slide 7 from the securing layer. A bump against one side of the projectile can possibly cause displacement of one raft body from the raft layer by the ball compressing the spring 18, but the other ball then always locks the slide against displacement "during firing of the projectile the slide is always displaced to the reinforcement layer with either tail 15 coated in the middle of the channel 14. This is because the balls 16, 17 are displaced from the sparring grip during the projectile rotation of the projectile while the springs 19 are compressed. The slide 7, which has a relatively large weight, is never exactly weight-centered, the displacement of the slide in the spar 5 is relieved within the barrel due to the long acceleration of the projectile, which means that the slide is pressed with great force against the bottom 6 of the spar and by the friction against it is retained in the spar layer. to the deceleration process, ie the paralyzed electric tube, the centrifuge overcomes The force on the slide frictional resistance, so. that the slide is displaced to the reinforcement layer. Then the projectile is at a safe distance. Iran launch site.

I axiella borrningar 22 i sliden aro anordnade sparrvikter 22, vilka Oro avsedda att samverka med motsvarande borrningar 24 i sakringshuset. Nar sliden under projektilens retardation flarskjutits at ena anden av sparet 5 kommer sparrvikten 22 att genom sin massakraft forskjutas in i det motsvarande halet 24, sa att sliden sakras mot forskjutfling, sedan den en gang kommit till armeringslaget. Arranged in axial bores 22 in the slide are ratchet weights 22, which are intended to cooperate with corresponding bores 24 in the fuse housing. When the slide during the deceleration of the projectile has been fired at one end of the ridge 5, the ridge weight 22 will be displaced by its mass force into the corresponding haul 24, so that the slide is secured against displacement, once it has reached the reinforcement layer.

Uppfinningen är icke begransad till det pa ritningen visade utforingsexemplet, utan kunna atskilliga konstruktiva forandringar vidtagas inona uppfinningens ram. Sparrkropparna behova lake nodvandigtvis besta av runda: kulor,.blott de heist ha en rundad spats. The invention is not limited to the exemplary embodiment shown in the drawing, but several constructive changes can be made within the scope of the invention. The sparse bodies of the lake necessarily have to consist of round: bullets, only they have a rounded spike.

Huset 1 Or gemensam barare av sprangkapseln 2, 3 och detonatorn, sa att detonator och Sprangkapsel med sakring kan latt monteras i projektilen som en enhet. The housing 1 is a common carrier of the detonator 2, 3 and the detonator, so that the detonator and detonator with fuse can be easily mounted in the projectile as a unit.
