Description

Przedmiotem wynalazku jest bezpiecz¬ nik bezwladnika umozliwiajacy bardzo pro¬ sta i zwiezla konstrukcje zapalnika, jaka jest wymagana np. do malokalibrowej a- municji wybuchowej.Wynalazek polega na tern, ze bezwlad¬ nik posiada jeden lub kilka narzadów za¬ bezpieczajacych tak wykonanych, iz zapal¬ nik zostaje samoczynnie zabezpieczony.Odbezpieczenie zapalnika moze tylko wtenczas nastapic, gdy pocisk nie ma juz przyspieszenia, co nastepuje po odbyciu pewnej drogi, przez uzycie kilku ukladów takich narzadów zabezpieczajacych osiaga sie, ze zawsze jeden z narzadów nastawia sie samoczynnie w ten sposób, ze zapewnia zabezpieczenie zapalnika równiez przy na¬ tezeniu na uderzenie. Narzady moga pod¬ czas swego przesuwu w polozenie zabez¬ pieczone wyprzedzac bezwladnik lub prze¬ suwac sie razem z bezwladnikiem.Na rysunkach dla przykladu przedsta¬ wiono formy wykonania wynalazku.Fig. 1 przedstawia bezwladnik 1, przy¬ trzymywany zapomoca zawleczki 2, scina¬ nej przy uderzeniu. W kadlubie 3 zapalni¬ ka znajduje sie kilka skosnie do jego osi nachylonych wydrazen 4, 5, 6, 7, w których sa swobodnie umieszczone kulki 8, 9, 10 i 11 tak, iz przynajmniej dwie kulki zabez-pieczaj a bezwladnik, niezaleznie od tego, w jakiem polozeniu znajduje sie zapalnik.V ?Gycly na be^w^adaik oddzialywa dodat¬ nie przyspieszenie, np. podczas ruchu poci¬ sku w lufie dziala, to kulki znajduja sie w wydrazeniach 5, 6 w takiem polozeniu, ze zapewniaja zabezpieczenie zapalnika. Przy uderzeniu pocisku glowica o przeszkode lub przy zatrzymaniu w lufie dziala, czyli, gdy pocisk otrzyma ujemne przyspieszenie, przesuwaja sie kulki w wydrazeniach 4 i 7 w takie pólcienie, które zapewnia zabez¬ pieczenie zapalnika. Dopiero gdy pocisk o- pusci lufe dziala i nie ma juz przyspiesze¬ nia, zapalnik zostaje zupejknie odbezpieczo¬ ny pod dzialaniem sily odsrodkowej.Zupelnie podobne jest urzadzenie we¬ dlug fig. 2, rózniace sie tern od poprzed¬ niego, ze wydrazenia 4 i 6, wzglednie 5 i 7, maja wspólne osie, wskutek czego wyrób jest ulatwiony. Wydrazenia sa w tym przy¬ padku wykonane w jednej plaszczyznie, lecz mozna je takze wykonac w kilku pla¬ szczyznach w wiekszej ilosci.W przykladzie wykonania wedlug fig. 3 kulki 8 i 10 sa. umieszczone w wydraze¬ niach 5 i 6 nad kolnierzem 12 z takim lu¬ zem 13, iz zawsze, gdy na pocisk oddzialy¬ wa ujemne przyspieszenie,, kulki wyprze¬ dzaja bezwladnik, przesuwajac sie w polo¬ zenie uwidocznione linja kreskowana, a na¬ stepnie zabezpieczaja bezwladnik, opiera¬ jac sie na powierzchniach 14 i 15.Podobny jest przyklad wykonania we¬ dlug fig. 4, rózniacy sie tern, ze swobodny przesuw kulek osiaga sie przez powieksze¬ nie srednicy 18 wydrazen 5 i 6, przyczem kulki 8 i 10 zatrzymuja sie na krawedziach 16 i 17. Gdy pocisk ma dodatnie przyspie¬ szenie, kulki zajmuja równiez polozenie dolne i zabezpieczaja wskutek tego bez¬ wladnik.W przykladzie wykonania wedlug fig. 5 kulki 8 i 10 znajduja sie w wydrazeniach 19 i 20 bezwladnika 1. Kulki przesuwaja sie razem z bewladnikiem 1 i zatrzymuja sie na krawedziach 16 i 17. Kulki moga sie wysuwac tylko pod dzialaniem sily odsrod¬ kowej, przyczem opieraja sie one na po¬ wierzchniach 21 i 22 skosnych wydrazen 5 i 6 i podnosza bezwladnik, który nieco sci¬ ska wtedy sprezyne 23.Zupelnie podobny jest bezpiecznik we¬ dlug fig. 6, rózniacy sie od poprzedniego tylko tern, ze wydrazenia 5 i 6 sa zaopa¬ trzone we wglebienia 21 i 22 stanowiace o- parcie dla kulek.W przykladzie wedlug fig. 7 bezwlad¬ nik przy wstrzasie od wystrzalu przezwy¬ cieza opór sprezyny 24, poczem kulki 8, 10 i t, d. po ustaniu dodatniego przyspieszenia wpadaja pod dzialaniem sily odsrodkowej do wydrazen 25. Dzialanie poza tern jest takie samo jak w innych przykladach wy¬ konania.Przyklad wykonania wedlug fig. 8 róz¬ ni sie od poprzedniego tylko tern, ze na bez¬ wladnik 1 jest nalozona tulejka 26, która pod dzialaniem sprezyny 24 lub innego na¬ rzadu przytrzymuje kulki 8, 10 i t. d. we wglebieniu 27. PLThe subject of the invention is an inertia fuse enabling a very simple and compact fuse structure, as is required, for example, for a small caliber explosive radio. The invention consists in the fact that the inertia inertia fuse has one or more safety devices so made that the fuse is self-securing. The fuze can only be released when the projectile is no longer accelerating, which takes place after a certain distance, by using several arrays of such securing devices, it is achieved that always one of the organs adjusts itself in this way, that it provides protection of the fuse also in case of impact. The tools may, during their movement into the secured position, overtake the inertia or move together with the inertia. The drawings show, by way of example, embodiments of the invention. 1 shows an inertia 1 held by a pin 2 which was cut on impact. In the fuse's fuselage 3 there are several inclined slots 4, 5, 6, 7 inclined to its axis, in which the balls 8, 9, 10 and 11 are freely placed, so that at least two balls protect the trigger, irrespective of the position of the fuse. V? Gycly, the beam is influenced by a positive acceleration, e.g. during the movement of a bullet in the barrel it works, the balls are in the holes 5, 6 in such a position that they ensure fuse protection. When the projectile hits an obstacle or when it stops in the barrel, it works, that is, when the projectile obtains negative acceleration, the balls in recesses 4 and 7 move into half-shades which ensure the protection of the fuse. Only when the projectile blows the barrel operates and there is no acceleration, the fuse is completely deprotected under the action of centrifugal force. The device according to Fig. 6 or 5 and 7 have common axes, which makes the product easier. The protrusions are in this case made in one plane, but can also be made in several planes in greater numbers. In the embodiment according to FIG. 3, the beads 8 and 10 are. placed in the portions 5 and 6 above the flange 12 with such a clearance 13 that whenever a negative acceleration affects the projectile, the balls overtake the inertia, moving towards the position shown by the dashed line, and the the step steps secure the inertia, resting on the surfaces 14 and 15. A similar embodiment is shown in Fig. 4, the differing terrain, that the free movement of the balls is achieved by increasing the diameter 18 of the holes 5 and 6, with the ball 8 and 10 stop at edges 16 and 17. When the projectile has positive acceleration, the balls also occupy the down position and thereby secure the ankle. In the example of the embodiment according to Fig. 5, the balls 8 and 10 are in recesses 19 and 20 of inertia 1 The balls move with the bead 1 and stop at the edges 16 and 17. The balls can only be ejected under the influence of centrifugal force, they rest on the surfaces 21 and 22 of the oblique holes 5 and 6 and lift the inertia, which is The spring 23 is then slightly constricted. The fuse according to Fig. 6 is quite similar, the only difference from the previous one being that the holes 5 and 6 are fitted with recesses 21 and 22 which support the balls. according to Fig. 7, the inertia during the shock of the shot overcomes the resistance of the spring 24, then the balls 8, 10 and t, d. after the cessation of positive acceleration, fall under the action of centrifugal force into the cavities 25. The effect outside the zone is the same as in other examples The embodiment according to Fig. 8 differs from the previous one only in that a sleeve 26 is applied to the ancillary 1, which, under the action of a spring 24 or other organ, holds the balls 8, 10 and so on in the cavity 27 .

Claims

Patent claims. 1. The inertia fuse, characterized by the fact that it is formed by a vent in the fuse body (3) surrounding the inertia fuse (1), conduits (4, 5, 6, 7) to pass freely through them safety devices ( 8, 9, 10, 11), which rest on the edges of the indicated expressions, while these edges (4, 5, 6, 7) are so inclined that with acceleration or deceleration of the projectile the safety devices move towards the inertia and they secure it.

2. Fuse according to claim 1, a significant area that its extrusions have the shape of straight channels, differently inclined with respect to the axis of the inertia.

3. Fuse according to claim 2f is a significant tern that each two channels (6, 8, 5, - 2 -U), connecting on opposite sides with the expression for the inertia, have a common axis.

4. Fuse according to claim According to any one of claims 1 to 3, characterized by the fact that the outlets of the channels (4, 5, 6, 7) to the inertial expression are in groups of equal height. 5. Fuse according to claim 4, the significant point is that the safety devices for each group of channels connecting at the same height with the inactor component interact with a separate collar (12). 6. Fuse according to claim 5, the significant point is that the securing devices (8, 9, 10, 11) are mounted with a play (13) in the axial direction relative to the flange (12) in the axial direction, so that they can overtake the tool moving from unlocked to secured position. 7. Fuse according to claim 1 - 5, characterized by the fact that the securing devices (8, 9, 10, 11) are placed in the cavities, which are made in the inertia opposite the outlets of the guide channels to the expulsion of this inertia, as a result of which the inertia deprotection under the action of The centrifugal force on the securing devices occurs only when the inertia is displaced by an appropriate distance in the axial direction. 8. Fuse according to claim 1 - 5, characterized by the fact that the securing devices (8, 9, 10, 11) adjacent to the inertia torch flanges rest on the recesses (27) in the fuse's fuselage (3) surrounding the inertia torch (1) and are held in the secured position by means of the spring (24), since the sliding of these organs from the secured position can only occur by axial displacement of the index and compression of the spring. 9. Fuse variant according to claim 7, characterized in that the safety devices fit in the recesses made on the sleeve (26), which is guided along the axis of the inertia and under the pressure of the spring.
