Description
PLASTIČNI TULEC S PREGRADOPLASTIC SHEET WITH PARTITION
Predmet izuma je plastični tulec s pregrado, predvsem za projektil ročnega orožja kot je npr. krogla naboja puške ali pištole, pri čemer je tulec projektila izdelan iz plastike ali njej podobnega materiala, ki omogoča enostavno in ceneno izvedbo tulca, poleg tega pa omogoča z izvedbo pregrade znotraj tulca redukcijo volumna samega tulca. Izum sodi v razredThe object of the invention is a plastic shell with a barrier, especially for a handgun projectile such as a a bullet of a rifle or pistol, the projectile sleeve being made of plastic or a similar material, which enables the sleeve to be easily and inexpensively provided, and also allows the volume of the sleeve to be reduced by carrying out a barrier within the sleeve. The invention belongs to the class
F 42B 07/06 mednarodne patentne klasifikacijeF 42B 07/06 International Patent Classification
Tehnični problem, ki ga predloženi izum uspešno rešuje je konstrukcijska rešitev izdelave tulca, npr. za kroglo naboja ročnega orožja, z izboljšanimi cenovnimi lastnostmi glede materiala in možnostjo regulacije tlaka v tulcu pri aktivaciji smodniškega polnjenja.A technical problem that the present invention successfully solves is a structural solution for the manufacture of a sleeve, e.g. for a handgun bullet, with improved material price properties and the ability to regulate the pressure in the sleeve when firing gun powder.
Tulec za kroglo naboja ročnega orožja, je v znanih izvedbah izdelan predvsem iz medenine z različnimi izdelavnimi postopki. Tako izdelan tulec je stroškovno problematičen, tako za bojne naboje, kot tudi pri uporabi za kroglo, ki je namenjena začasni onesposobitvi cilja in nima ubojnih lastnosti in je izdelana iz mehkejšega materiala, plastike ali gume.In the known embodiments, the bullet for a bullet of a small arms is mainly made of brass with various manufacturing processes. The sleeve made in this way is cost-effective, both for combat bullets and for use on a bullet designed to temporarily incapacitate a target that has no killer properties and is made of softer material, plastic or rubber.
Znane so izvedbe plastični tulcev, ki imajo skupno slabo lastnost, da imajo nizko strukturno trdnost in taki tulci počijo pri streljanju. Plastični tulec po patentnem dokumentu EP 1 388 726 je značilen po tem, da se • · mu notranji premer vzdolž glavne osi zmanjšuje proti dnu tulca, nima pa možnosti regulacije tlaka pri aktiviranju smodniškega polnjenja.Embodiments of plastic sleeves are known to have a common bad property of having low structural strength and such sleeves burst when fired. The plastic sleeve according to patent document EP 1 388 726 is characterized by the fact that its inner diameter along the main axis decreases towards the bottom of the sleeve, but does not have the ability to regulate the pressure during the activation of gunpowder filling.
Plastični tulec s pregrado po izumu ima v notranjosti izvedeno pregrado, ki je del plastičnega telesa tulca in s položajem katere lahko pri izdelavi tulca reduciramo notranji volumen tulca.The plastic sleeve with a barrier according to the invention has a barrier inside that is part of the plastic body of the sleeve and with the position of which the inner volume of the sleeve can be reduced when making the sleeve.
Izum bomo podrobneje obrazložili na osnovi izvedbenega primera in pripadajočih slik, ki katerih kaže:The invention will be explained in more detail on the basis of an embodiment and accompanying drawings, showing:
slika 1 projektil ročnega orožja s plastičnim tulcem s io pregrado po izumu v prerezu A-A;Fig. 1 is a projectile of a handgun with a plastic sleeve with an io barrier according to the invention in section A-A;
slika 2 prerez plastičnega tulca s pregrado po izumu.Figure 2 is a cross-section of a plastic sleeve with a barrier according to the invention.
Plastični tulec s pregrado po izumu predstavlja telo 1, ki ima v notranjosti izvedeno pregrado 2, ki razdeli notranjost telesa 1 na dve komori Α,Β. V komori A je smodniško polnjenje, komora B pa je prazna. V spodnjem delu telesa 1 je pri dnu 3 tulca izvedena srajčka 4, ki z notranje strani oklepa dno 3 in omogoča dobro tesnjenje med dnom 3 in telesom 1 tulca.The plastic sleeve with the barrier according to the invention represents a body 1 having an inner barrier 2 which divides the interior of the body 1 into two chambers Α, Β. In chamber A there is gunpowder filling and chamber B is empty. In the lower part of the body 1, a shirt 4 is formed at the bottom 3 of the sleeve, which encloses the bottom 3 from the inside and allows a good seal between the bottom 3 and the body 1 of the sleeve.
V komori A nameščeno smodniško polnjenje se aktivira z vžigalno kapico v dnu 3 projektila. Ta povzroči aktivacijo smodniškega polnjenja v komori A, ki začne sproščati velike količine plina. Tlak, ki se pri tem ustvarja, povzroči odmik krogle od tulca, ki nato nadaljuje pot skozi cev in preko strelne linije do tarče. Pri znanih izvedbah medeninastih tulcev je volumen tulca določen samo z velikostjo tulca, medtem ko je pri plastičnem tulcu s pregrado po izumu, možno z različno postavljeno pregrado 2, torej s spreminjanjem, oziroma prilagajanjem volumna komore A proti komori B, regulirati tlak, ki se razvije pri aktivaciji smodnika. Več kot je praznega volumna (torej večja kot je komora B), večji tlak se lahko razvije. S premikanjem pregrade 2 pri izdelavi plastičnega tulca po izumu lahko tako reguliramo tlake v preciznem območju.In the chamber A, the gunpowder charge installed is activated by the firing cap in the bottom 3 of the projectile. This causes the activation of gunpowder charge in chamber A, which begins to release large quantities of gas. The resulting pressure causes the ball to move away from the sleeve, which then proceeds through the barrel and across the firing line to the target. In the known embodiments of the brass sleeves, the volume of the sleeve is determined only by the size of the sleeve, while in the plastic sleeve with a barrier according to the invention, it is possible with a differently arranged barrier 2, ie by varying or adjusting the volume of chamber A against chamber B, to regulate the pressure which develops at gunpowder activation. The greater the void volume (hence the larger the chamber B), the greater the pressure can develop. By moving the barrier 2 in the manufacture of the plastic sleeve according to the invention, the pressures in the precision range can thus be adjusted.
Ker je od tlaka odvisna hitrost krogle, lahko matematično zelo precizno določimo velikost komore A, glede na količino smodniškega polnjenja in io mesto postavljanja pregrade 2, za želeno hitrost krogle. Na ta način lahko zmanjšamo hitrost krogle tudi do te mere, da se lahko strelivo označi kot »manj ubojno strelivo«, oziroma kot strelivo, ki je namenjeno začasni onesposobitvi cilja in nima ubojnih lastnosti.Since the velocity of the ball depends on the pressure, we can mathematically very accurately determine the size of the chamber A, depending on the amount of gunpowder filling and io the location of the barrier 2, for the desired velocity of the ball. In this way, the speed of the bullet can also be reduced to such an extent that the ammunition can be designated as "less lethal ammunition", or as ammunition intended to temporarily disable the target and have no killing properties.
