Description
Laderamme. Charging frame.
Foreliggende oppfinnelse vedrører en laderamme for transport og tilførsel av et antall relativt tunge patroner til et skytevåpens magasin. The present invention relates to a charging frame for transporting and supplying a number of relatively heavy cartridges to a firearm's magazine.
Transporten av tunge patroner for au-tomatiske, transportable skytevåpen med-fører tekniske og taktiske problemer fordi skytevåpnet av hensyn til vekten ikke kan utføres med et magasin som inneholder mange patroner og fordi skytevåpnets magasin hurtig må kunne forsynes med nye patroner uten at noen manuell håndtering av patronene er nødvendig. The transport of heavy cartridges for automatic, transportable firearms entails technical and tactical problems because, due to the weight, the firearm cannot be carried with a magazine containing many cartridges and because the firearm's magazine must be able to be quickly supplied with new cartridges without any manual handling of the cartridges is required.
Formålet med oppfinnelsen er å skaffe en laderamme ved hvis hjelp problemene kan løses. Laderammen ifølge oppfinnelsen er av den art hvor patronene er orientert i hovedsaken parallelt ved siden av hverandre i et felles plan og holdes fast til en bærende ramme som er forsynt med utsparinger tilsvarende patronenes ytre form. Oppfinnelsen utmerker seg ved at flere fastholdende elementer som omslutter hver sin patron, er sammenkoblet på en sådan måte at flere patroner frigjøres fra laderammen samtidig, og at hvert fastholdende element ved sin ene ende er fast forbundet med den bærende ramme og ved sin annen ende forbundet med den samme bærende ramme over en sperreanordning, således at flere patroner ved sperreanord-ningens utløsning, ved sin egen vekt faller ned i en retning vinkelrett på det nevnte, for patronene felles plan. The purpose of the invention is to provide a charging frame with the help of which the problems can be solved. The loading frame according to the invention is of the kind where the cartridges are oriented essentially parallel next to each other in a common plane and are held firmly to a supporting frame which is provided with recesses corresponding to the outer shape of the cartridges. The invention is distinguished by the fact that several retaining elements that enclose each cartridge are interconnected in such a way that several cartridges are released from the charging frame at the same time, and that each retaining element is firmly connected at one end to the supporting frame and at its other end connected with the same supporting frame over a locking device, so that several cartridges, when the locking device is released, fall down by their own weight in a direction perpendicular to the aforementioned, for the cartridges common plane.
Oppfinnelsen skal beskrives i det føl-gende under henvisning til tegningen, hvor fig. 1 viser i perspektiv en sammenlagt laderamme ifølge oppfinnelsen, fig. 2 i perspektiv og delvis i snitt den på fig. 1 viste ramme i utfelt stilling, og fig. 3 i perspektiv og i snitt en detalj av rammen ifølge fig. 1 og 2. The invention will be described in the following with reference to the drawing, where fig. 1 shows in perspective a combined charging frame according to the invention, fig. 2 in perspective and partly in cross-section the one in fig. 1 showed the frame in the unfolded position, and fig. 3 in perspective and in section a detail of the frame according to fig. 1 and 2.
På tegningen angir 1 og 2 to ramme-deler som er forbundet med hinannen ved hjelp av et hengsel 3. På motstående sider i hver rammedel er der anordnet flenser 4 med sirkelbueformede utsparinger, idet der i patronenes 6 projektildeler finnes spor for samvirke med de nevnte utsparinger så patronene låses i lengderetningen og ligger parallelt ved siden av hverandre. Patronene 6 fastholdes i utsparingene 5 ved hjelp av fastholdende elementer i form av bøyelige hengselbånd 7. Et av disse er tydelig vist på fig. 3 og er ved sin ene ende forsynt med et festeorgan 8 som fastholdes i en styring 9 ved hjelp av en skrue 10; denne muliggjør også båndets tilspenning mot patronen. I den annen ende er bån-det 7 forsynt med et festeorgan 11 som har en åpning 12 og som trees inn på en opphengningsarm 13. Denne arm 13 er dreibar på en tapp 14 og dens annen gren ligger an mot et fremspring 15 på en skin-ne 16 som strekker seg i hele rammedelens 1 lengde og som er forsynt med tilsvarende fremspring for låsing av de øvrige bånd i rammedelen. En aksel 17 er dreibart lagret i rammedelens 1 ytre ende og er forsynt med en vektarm 18 og to vektarmer 19, hvorav de to sistnevnte er anordnet en i hver akselende. Hver In the drawing, 1 and 2 indicate two frame parts which are connected to each other by means of a hinge 3. On opposite sides of each frame part there are arranged flanges 4 with circular arc-shaped recesses, as there are grooves in the projectile parts of the cartridges 6 for cooperation with the aforementioned recesses so that the cartridges are locked in the longitudinal direction and lie parallel next to each other. The cartridges 6 are retained in the recesses 5 by means of retaining elements in the form of flexible hinge bands 7. One of these is clearly shown in fig. 3 and is provided at one end with a fastening device 8 which is held in a guide 9 by means of a screw 10; this also enables the belt to be tensioned against the cartridge. At the other end, the track 7 is provided with a fastening device 11 which has an opening 12 and which is threaded onto a suspension arm 13. This arm 13 is rotatable on a pin 14 and its other branch rests against a projection 15 on a rail -ne 16 which extend the entire length of the frame part 1 and which are provided with corresponding protrusions for locking the other bands in the frame part. An axle 17 is rotatably mounted at the outer end of the frame part 1 and is provided with a weight arm 18 and two weight arms 19, of which the latter two are arranged one at each axle end. Each
av vektarmene 19 står dreibart i for-bindelse med et ledd 20 som på sin side of the weight arms 19 is rotatably connected to a link 20 which in turn
er dreibart forbundet med en konsoll 21 på is rotatably connected with a console 21 on
skinnen 16. Rammedelen 2 er forsynt med the rail 16. The frame part 2 is provided with
to skinner av lignende art som skinnene 16.; two rails of a similar nature to the rails 16.;
opphengningen av skuddene er utført på the suspension of the shoots is carried out on
samme måte. same way.
Den beskrevne anordning virker på The described device works on
følgende måte. Fra den på fig. 1 viste sam-menlagte stilling svinges rammedelen 1 the following way. From the one in fig. 1 shown combined position, the frame part 1 is swung
hensiktsmessig ved hjelp av en løftekran appropriate by means of a lifting crane
til den på fig. 2 viste stilling. Derpå løftes to the one in fig. 2 shown position. Then lifted
hele rammen 1, 2 med horisontalt hengende the entire frame 1, 2 with horizontal hanging
patroner og transporteres til skytevåpnet, cartridges and transported to the firearm,
hvor rammen senkes ned — fremdeles méd where the frame is lowered — still méd
patronene hengende i horisontalplanet. the cartridges hanging in the horizontal plane.
På hver side av skytevåpenets magasin On either side of the firearm's magazine
er der anordnet en tapp 22, hvorav bare a pin 22 is arranged there, of which only
den ene er vist på fig. 2. Når tappen 22 one is shown in fig. 2. When the pin 22
støter mot vektarmen 18 vil akselen 17 collides with the weight arm 18, the shaft 17
dreies mot solen og skinnene 16 beveger is turned towards the sun and the rails 16 move
seg mot høyre på fig. 2 og 3. Når frem-springene 15 trekkes vekk fra låsarmene towards the right in fig. 2 and 3. When the projections 15 are pulled away from the locking arms
13, vil disse av patronvekten svinges ned-ad, hvorunder festeorganene 11 samtidig 13, these will be swung downwards by the cartridge weight, under which the fastening means 11 at the same time
frigjøres, således at alle patronene frigjø-res fra laderammen på samme tid. is released, so that all the cartridges are released from the loading frame at the same time.
