Description

Przedmiot wynalazku niniejszego sta¬ nowi zapalnik uderzeniowy do granatów recznych. Istota wynalazku polega na za¬ bezpieczeniu zapalnika od wypadku przy magazynowaniu, transporcie i przy wy¬ padnieciu z reki po odbezpieczeniu przez wyjecie przetyczki, Zupelne odbezpiecze¬ nie zapalnika nastepuje w powietrzu po rzucie granatu i po jego przelocie kilku metrów.Na zalaczonym rysunku przedstawiono schematycznie przekroje rozmaitych od¬ mian wykonania zapalnika wedlug wyna¬ lazku, w których jednakowe czesci zapal¬ nika sa oznaczone tymi samymi cyframi, W kadlubie zapalnika wedlug fig. 1 jest umieszczony bezwladnik, skladajacy sie z dwóch polówek 2 i 2', z których w jednej jest umocowana iglica 3 i osadzona sprezyna 9, a w drugiej — splonka zapa¬ lajaca 7 i rurka 4. Pomiedzy te polówki jest wstawiony dajacy sie wysuwac swo- rzen 8. Górna polówka jest odpychana od dolnej za pomoca sprezyny 9. Rurka 4 sluzy za prowadnice iglicy 3. Sprezyna 9 jest osadzona na rurce 4 i po wysunieciu sie sworznia 8 zapobiega przedwczesnemu zbiciu splonki 7.Sworzen 8 posiada kuliste zgrubienie, które sluzy do nalezytego uszczelnienia otworu 1'". Rozdwojony koniec sworznia obejmuje rurke 4 z obu stron uniemozli-wiajac w polozeniu zabezpieczajacym zbi¬ cie splonki zapalajacej. „ + * Sprezyna 10 jes^ nawinieta na os 13, osadzona" w glówce sworziiia. Górny ko¬ niec sprezyny jest przymocowany do dzwi¬ gni recznej 11, wskutek czego przy na¬ cisku na dzwignie reczna ku dolowi spre¬ zyna ta naciska na glówke sworznia 8, który uszczelnia otwór. Po wyjeciu prze¬ tyczki 14 i rzucie granatu sprezyna 10 od¬ rzuca dzwignie 11, która odpada od gra¬ natu i wyciaga za soba sworzen 8.Po odbezpieczeniu zapalnika, obie po¬ lówki 2 i 2' bezwladnika, w chwili uderze¬ nia granatu o przeszkode, stykaja sie z soba i powoduja jego wybuch.W kadlubie 1 zapalnika wedlug fig. 6 kulka 2 steinowi górny bezwladnik i jest osadzona na obsadzie 4 iglicy 3. Obsada 4 jest podtrzymywana sworzniem 8. Dzia¬ lanie sworznia i dzwigni recznej tego za¬ palnika jest takie samo jak w zapalniku wedlug fig. 1.Zapalnik wedlug fig. 3 posiada nieco odmienna budowe.W kadlubie zapalnika znajduje sie ku¬ listy bezwladnik 2, umieszczony w klesz¬ czach 4 uchwytu 16 i dociskany do niego pokrywa 18. Wewnatrz kleszczy znajduje sie sprezyna 9 osadzona na osi 12, przy czym kleszcze 4 górnymi ramionami pod¬ trzymuja kulke 2, dolnymi — iglice 3. Po odbezpieczeniu dzwigni recznej i rzucie granatu dzwignia ta odpada i wyciaga za soba sworzen 8. Po wysunieciu sie sworz¬ nia z otworu ucha pokrywy 18, zostaje zwolniona zapadka 8' (fig. 4), przy czym pokrywa 18, pod naciskiem sprezyny 10, wysuwa sie z kadluba zapalnika i pociaga za soba klamerke 17, która zsuwajac sie z wystepu 1" kadluba zapalnika odchyla sie i odrzuca zapadke 8*. Po wysunieciu sie pokrywy 18 z kadluba zapalnika zostaje zwolniony bezwladnik 2, który po zetknie¬ ciu sie granatu z przeszkoda wskutek wstrzasu wypada z kleszczy, po czym sprezyna 9 rozchyla te kleszcze 4 i zwalnia iglice 3, która pod naciskiem sprezyny 5 zbija splonke 7.Do dzwigni recznej 11 jest przymoco¬ wana cienka sprezynujaca tasma 11', owi¬ nieta dookola osi 20 osadzonej w kadlubie zapalnika, która po odbezpieczeniu dzwig¬ ni recznej i rzucie granatu hamuje podczas lotu obrót dzwigni, wskutek czego opóznia jej odpadniecie i wysuniecie sie sworznia 8, co nastepuje w powietrzu po przelocie kilku metrów.Zapalnik wedlug fig. 7 posiada bez¬ wladnik 2, który przytrzymuje kulki lub rolki 2*, zabezpieczajace iglice 3, przy czym dzialanie tego zapalnika jest takie samo jak zapalnika wedlug fig. 3.Na ogon kadluba zapalnika jest nalo¬ zona luska zawierajaca splonke pobudza¬ jaca, po czym jest nakrecona oslbna 15. PLThe present invention relates to a hand grenade impingement fuse. The essence of the invention consists in securing the fuse against accidents during storage, transport and in the event of falling out of hand after unlocking the fuse by removing the pin. The fuse is completely unlocked in the air after the grenade is thrown and after it has flown a few meters. cross-sections of various variants of the fuze according to the invention, in which the same parts of the fuze are marked with the same numerals. In the fuse's body according to Fig. 1 there is an indexer, consisting of two halves 2 and 2 ', one of which a firing pin 3 and a spring 9 are attached, and in the other - an incendiary cord 7 and a tube 4. Between these halves a sliding pin 8 is inserted. The upper half is pushed from the lower half by a spring 9. The tube 4 serves as guides needle 3. The spring 9 is mounted on the tube 4 and after the pin 8 protrudes, it prevents premature collapse of the thread 7. The pin 8 has a spherical thickening, which is used to properly seal the 1 "" hole. The split end of the pin encloses the tube 4 on both sides, preventing the incapacitation of the incendiary flap in the securing position. "+" Spring 10 is wound on the axle 13, embedded "in the head of the pin. The upper end of the spring is attached to the hand lever 11, so that when the hand lever is pressed downward, the spring presses the head of the pin. pin 8, which seals the hole.After removing the pin 14 and throwing the grenade, the spring 10 throws away the lever 11, which falls off the granule and pulls the pin 8 behind it. After unlocking the fuse, both halves 2 and 2 'of the inertia when the grenade hits an obstacle, they touch each other and cause it to explode. In the fuselage 1 of the fuse, according to Fig. 6, the ball 2 has the upper tailstock and is mounted on the firing pin holder 4 3. The holder 4 is supported by a pin 8. The gun The casting of the pin and the lever of this torch is the same as in the fuse according to Fig. 1. The fuse according to Fig. 3 has a slightly different structure. In the fuze body there is a tool 2, placed in the clamps 4 of the handle 16 and cover 18 is pressed against it if there is a spring 9 mounted on the axis 12, with the upper arms 4 supporting the ball 2, the lower arms - the needles 3. After unlocking the hand lever and throwing the grenade, the lever falls off and pulls the pin 8. After the bolt is pulled out from the opening of the cover 18, the catch 8 'is released (Fig. 4), the cover 18, under the pressure of the spring 10, slides out of the fuse body and pulls the clip 17, which, sliding down from the protrusion 1 "of the fuse body, tilts and throws back the latch 8 *. After the cover 18 extends from the fuse body. the actuator 2 is released, which falls out of the forceps after the grenade comes into contact with the obstacle, and the spring 9 opens the tongs 4 and releases the needle 3, which, under the pressure of the spring 5, breaks the flap 7. The hand lever 11 is fastened to a thin elastic band 11 ', wrapped around the axis 20 embedded in the fuselage fuselage, which, after unlocking the hand lever and throwing a grenade, inhibits the rotation of the lever during the flight, thus delaying its fall off and the extension of the pin 8, which occurs in the air after the flight The igniter according to fig. 7 has an accessory 2 which holds the balls or rollers 2 *, securing the needles 3, the operation of this fuse being the same as that of the fuze according to f ig. 3. On the tail of the fuse's fuselage there is a husk containing the stimulating filament, and then the shell is screwed on.
