Description

25 'I 30 516 592 Figur 4 visar schematiskt tryckplattan anbringad till grana- tens undre del. Figure 4 schematically shows the pressure plate attached to the lower part of the grenade.

Figur 5 visar granaten och dess nedre del med tryckplattan vid avfyrningen ur eldröret.Figure 5 shows the grenade and its lower part with the pressure plate when firing from the barrel.

Det är i det följande underförstått att den i figurerna visade nedre delen av granaten utgöres av en konventionell granat och att eldröret ur vilket granaten utskjutes också är konventio- nellt, varför dessa delar ej närmare beskrives. Med hänvisning nu till figuren 1 visas schematiskt nedre delen av den konven- tionella granaten 1, som har en drivsats 2. Drivsatsen pressas normalt in i en hålighet i granatens 1 botten och håligheten betecknas med 3. Drivsatsen har en tándhatt 4 som när granaten antändes påverkas av ett slagstift som tillhör eldröret. I fi- gur 1 visas hur som drivsatsen 2 blivit utdragen ur håligheten 3. I denna hålighet skall nu anbringas det som i det följande benämnes tryckplatta.In the following, it is understood that the lower part of the grenade shown in the figures consists of a conventional grenade and that the barrel from which the grenade is fired is also conventional, so these parts are not described in more detail. Referring now to Figure 1, the lower part of the conventional grenade 1 is shown schematically, which has a propellant 2. The propellant is normally pressed into a cavity in the bottom of the grenade 1 and the cavity is denoted by 3. The propellant has a toothed cap 4 which when the grenade is ignited affected by a percussion pin belonging to the barrel. Figure 1 shows how the drive set 2 has been pulled out of the cavity 3. In this cavity, what is hereinafter referred to as pressure plate must now be applied.

I figur 2 visas nu tryckplattan generellt betecknad med 5.Figure 2 now shows the pressure plate generally denoted by 5.

Tryckplattan 5 har en nedåt riktad hylsdel 6, i vilken den konventionella drivsatsen 2 kan införas med sin tändhatt 4. På tryckplattans 5 ovansida finns en gängtapp 7, på vilken en hylsdel 8 kan fastgângas. Hylsdelen 8 har en hålighet 9 och i denna kan inläggas en separationssats 10. Se figurerna 4 och 5. Drivsatsen 2 har förbindelse med håligheten och således se- parationssatsen via en kanal 11. Runt delen 8 kan anbringas en hylsa 12 som fastskruvas mot delen 8 medelst en mutter 13.The pressure plate 5 has a downwardly directed sleeve part 6, in which the conventional drive set 2 can be inserted with its spark plug 4. On the upper side of the pressure plate 5 there is a threaded pin 7, on which a sleeve part 8 can be fastened. The sleeve part 8 has a cavity 9 and a separation set 10 can be inserted in it. See Figures 4 and 5. The drive set 2 is connected to the cavity and thus the separation set via a channel 11. Around the part 8 a sleeve 12 can be arranged which is screwed against the part 8 by means of a nut 13.

Hylsans 12 ytterdiameter och form motsvarar håligheten 3 i granatens 1 botten så att hylsan 12 och därmed tryckplattan 5 underifrån kan inpressas i håligheten 3 och fixeras till lä- get. Håligheten 12 är dock längre än hylsans 12 längd. Detta 703533; 00-12-01 -/ 10 15 20 25 30 516 sšåàïï: " 3 läge visas delvis i figuren 3 där således hylsan 12 med delen 8 är på väg att införas i hàligheten 3.The outer diameter and shape of the sleeve 12 corresponds to the cavity 3 in the bottom of the grenade 1 so that the sleeve 12 and thus the pressure plate 5 can be pressed into the cavity 3 from below and fixed to the position. However, the cavity 12 is longer than the length of the sleeve 12. This 703533; 00-12-01 - / 10 15 20 25 30 516 sšåàïï: "3 position is shown partly in figure 3 where thus the sleeve 12 with the part 8 is about to be inserted into the cavity 3.

I figur 4 visas tryckplattan applicerad till granaten 1. Det skall härvid noteras att förbindelsen mellan granaten 1 och tryckplattan 5 i princip utgöres av gângförbindelsen mellan delen 8 och tappen 7 emedan hylsan 12 förutsättes vara så hårt inpressad i granaten underifrån att den svårligen kan utdra- gas.Figure 4 shows the pressure plate applied to the grenade 1. It should be noted here that the connection between the grenade 1 and the pressure plate 5 in principle consists of the passage connection between the part 8 and the pin 7, since the sleeve 12 is assumed to be so tightly pressed into the grenade from below that it is difficult to extend. gas.

I figur 4 visas således att tryckplattan befinner sig mot gra- natens 1 undersida. Vid avfyrning antândes drivsatsen 2 och en flamma från denna når genom kanalen 11 separationsladdningen 10. Denna har sådan kraft att den skjuter loss delen 8 från tryckplattans 5 ovansida, dvs. gângförbindningen mellan delen 8 och tappen 7 är tillräckligt svag för att tillåta att sepa- rationsladdningen särskiljer delarna. Därvid kommer delen 8 att förläggas på så sätt som visas i figur 5 därigenom att hå- ligheten 3 i granaten är tillräckligt lång att rymma delen 8 uppskjuten en bit från tryckplattan 5. I det i figur 5 visade läget är således tryckplattan frigjord från granaten 1 och denna och granaten skjutes av drivladdningen ut genom det ej visade eldröret och så snart granaten lämnat eldröret faller tryckplattan ur eldrörets öppning och granaten kan fri från tryckplattan 5 fortsätta sin bana.Figure 4 thus shows that the pressure plate is against the underside of the grenade 1. During firing, the drive set 2 is ignited and a flame from it reaches through the channel 11 the separation charge 10. This has such a force that it shoots off the part 8 from the upper side of the pressure plate 5, i.e. the threaded connection between the part 8 and the pin 7 is weak enough to allow the separation charge to distinguish the parts. The part 8 will then be placed in the manner shown in Figure 5 in that the cavity 3 in the grenade is long enough to accommodate the part 8 projecting a distance from the pressure plate 5. In the position shown in Figure 5, the pressure plate is thus released from the grenade 1. and this and the grenade are pushed by the propellant charge out through the fire tube (not shown) and as soon as the grenade has left the fire tube, the pressure plate falls out of the opening of the fire tube and the grenade can continue its path free from the pressure plate 5.

Inom ramen för uppfinningstanken finns variationer särskilt vad beträffar infästningen mellan tryckplattan och granatens botten för att den skall kunna lösgöras när drivsatsen antân- des. I det föregående har beskrivits en gängförbindelse mellan tappen 7 och delen 8 men denna kan naturligtvis vara en frik- tionskoppling. Form av brytstift kan också tänkas. 703533; 00-12-01Within the scope of the inventive concept, there are variations, especially with regard to the attachment between the pressure plate and the bottom of the grenade, so that it can be detached when the drive kit is ignited. In the foregoing, a threaded connection between the pin 7 and the part 8 has been described, but this can of course be a friction coupling. Form of break pin is also conceivable. 703533; 00-12-01
