Abstract

A reflex sight consisting of a partially transmitting reflex disc (2) that can be mounted on a weapon at an angle of 45 degrees to a line of sight (15) and an optical system (7) for mirroring a sight image in the reflex disc from a direction at right angles to the line of sight. The reflex disc (2) should be installed so that is can be retracted into the optical system's (7) accommodating housing (1), which, in turn, is mounted on the weapon with the reflex disc immediately in front of the position of the shooter's eye, and with the reflex disc's free edges bare in its extended state.<IMAGE>

Description

8302955-3 10 15 20 25 30 35 2 är en planvy av reflexsiktet enligt uppfinningen, fig 2 är en sidovy och fig 3 är en vy bakifrån av samma sikte. 8302955-3 10 is a plan view of the reflex sight according to the invention, Fig. 2 is a side view and Fig. 3 is a rear view of the same sight.

Reflexsiktet enligt den föredragna utföringsformen av föreliggande uppfinning består av ett hölje l och en reflexskiva 2, som utmed sin ena kant är infällbart och vridbart monterad vid höljet l medelst en axel 3.The reflective screen according to the preferred embodiment of the present invention consists of a housing 1 and a reflective disc 2, which along its one edge is retractably and rotatably mounted to the housing 1 by means of a shaft 3.

Medelst två kulsnäpp kan ett utfällt och ett infällt läge för reflexskivan 2 vara definierat. Härigenom upp- nås även att reflexskivan i sitt utfällda läge är lagrad undanfjädrande och detta lämpligen i bäda riktningarna.By means of two ball snaps, a retracted and a retracted position of the reflective disc 2 can be defined. In this way it is also achieved that the reflector disc in its unfolded position is stored resiliently and this is suitably in both directions.

Höljet l består av en platta 4 och en vid denna löstag- bart monterad kàpa 5. Plattan 4 har en försänkning 6 för upptagande av reflexskivan 2 i dennas infällda till- stånd. I plattan 4 är vidare ett genomgående hål upp- taget, i vilket reflexsiktets optiska system 7 är monte- rat. Det optiska systemet 7 innefattar en lins 8, en siktesbildsfilm 9, som är monterad i linsens 8 fokalplan och har en genomlysbar siktesbild, samt en lysdiod 10 för belysning av siktesbilden. Dessa komponenter är 'monterade i en hylsa ll, varvid lysdioden l0 är monterad centralt i en ljustransmitterande, mot en öppning 12 i höljet vänd skiva 13. Siktesbilden kan med fördel utgöras av ett hàrkors med.en central, för avstàndsbe- dömning avsedd.ring.The housing 1 consists of a plate 4 and a cover 5 detachably mounted thereon. The plate 4 has a recess 6 for receiving the reflective disc 2 in its retracted condition. A through hole is further accommodated in the plate 4, in which the optical system 7 of the reflex sight is mounted. The optical system 7 comprises a lens 8, a screen image film 9, which is mounted in the focal plane of the lens 8 and has a translucent screen image, and an LED 10 for illuminating the screen image. These components are mounted in a sleeve 11, the LED 10 being mounted centrally in a light transmitting disc facing an opening 12 in the housing 13. The screen image can advantageously consist of a crosshair with a central ring intended for distance assessment. .

'Ett till öppningen 12 i höljet l anslutande prisma 14 reflekterar frân en med en siktlinje 15 parallell rikt- ning 16 mottaget ljus mot lysdioden 10 och den mot öpp- ningen l2 vända skivan l3 för belysning av siktesbilds- filmen 9. Prismats 14 ljusmottagande yta l7 är lämpligen utformad som en samlingslins. Prismat kan vara löstagbart monterat och kan eventuellt ersättas av ett ljusavskär- mande lock.A prism 14 connecting to the opening 12 in the housing 1 reflects from a light received with a line of sight parallel to a direction 15 parallel to the LED 10 and the disc 13 facing the opening 12 for illuminating the screen image film 9. The light receiving surface of the prism 14 17 is suitably designed as a collection lens. The prism can be detachably mounted and can possibly be replaced by a light-shielding lid.

Fastän ej visat är_i höljet 1 och vid plattan 4 ett batteri monterat tillsammans med ett tidrelä för tidsbegränsad anslutning av lysdioden 10 till batteriet.Although not shown, in the housing 1 and at the plate 4 a battery is mounted together with a time relay for time-limited connection of the LED 10 to the battery.

Detta tidrelä är så utformat, att det är väsentligen strömlöst i inaktiverat tillstànd. Aktiveringen av tid- lO 15 20 25 30 35 azozsss-sd 3 reläet sker medelst en knapp 18 på höljets utsida.This time relay is designed so that it is substantially de-energized in the deactivated state. The activation of the relo 15 20 25 30 35 azozsss-sd 3 relay takes place by means of a button 18 on the outside of the housing.

Medelst en andra knapp 19 på höljets utsida kan den lysdioden pålagda spänningen växlas mellan två värden, så att lysdioden kan lysa starkt eller svagt. De båda knapparna är avtätade medelst ett membran. I stället för tidreläet kan vilken som helst mekanisk eller elek- trisk vippanordning utnyttjas för den tidsbegränsade anslutningen av lysdioden l0 till batteriet. öppningen 12 i kåpan 5 är tillsluten medelst en genomsynlig skiva 20, vilken liksom knapparna 18 och 19 är avtätad mot kåpan 5, Medelst 0-ringar är vidare kåpan 5 avtätad mot plattan 4 och är det optiska syste- met 7 avtätat mot plattan 4.By means of a second button 19 on the outside of the housing, the voltage applied to the LED can be switched between two values, so that the LED can shine bright or weak. The two buttons are sealed by means of a diaphragm. Instead of the time relay, any mechanical or electrical flip-flop device can be used for the time-limited connection of the LED 10 to the battery. the opening 12 in the cover 5 is closed by means of a transparent disc 20, which like the buttons 18 and 19 is sealed against the cover 5. By means of 0-rings, the cover 5 is further sealed against the plate 4 and the optical system 7 is sealed against the plate 4.

En hållare 21 för montering av reflexsiktet pà ett vapen är làsbar vid såväl höljet som vapnet medelst en tapp 22, 23, som är avsedd att ingripa i ett motsva- rande hål, och en genom en slits 24 åtdragbar skruv 25, 26. De två tapparna 22, 23 är vinkelräta mot var- andra, så att siktet lätt kan skottställas, Reflexsiktet enligt föreliggande uppfinning utgör ett kompakt sikte, som förhindrar varje problem med ackommodation och därför är utmärkt lämpat för skjutning med alla slags handeldvapen, inte minst hagelgevär.A holder 21 for mounting the reflex sight on a weapon is lockable at both the housing and the weapon by means of a pin 22, 23, which is intended to engage in a corresponding hole, and a screw 25, 26 which can be tightened through a slot 24. the pins 22, 23 are perpendicular to each other, so that the sight can be easily shot. The reflex sight according to the present invention is a compact sight, which prevents any problems with accommodation and is therefore excellent for shooting with all kinds of handguns, not least shotguns.

Medelst hàllaren Zl är reflexskivan således monterad omedelbart framför läget för skyttens öga vid skjutning.By means of the holder Z1, the reflective disc is thus mounted immediately in front of the position of the shooter's eye when firing.

Härigenom fås ett synfält utan någon som helst avgräns- ning, sà att riktning mot och följning av ett rörligt mål kan utföras med båda ögonen. Genom att reflexskivan gjorts infällbar i plattan 4 och gjorts undanfjädrande i sitt utfällda läge är risken för skada på reflexskivan mycket liten. Genom utformningen med öppningen 12 och prismat 14, som mottager ljus i målets riktning, uppnås vidare en eftersträvad balans mellan ljusstyrkan hos den inspeglade siktesbilden och själva målet. Möjlighet till att under olika ljusförhållanden åstadkomma lämplig balans är dessutom garanterad med hjälp av den mellan tvâ ljusstyrkor omställbara lysdioden 9. Genom anord- nandet av ett tidrelä säkerställas dessutom en läng livslängd hos batteriet.This gives a field of view without any demarcation, so that the direction and tracking of a moving target can be performed with both eyes. By making the reflective disc retractable in the plate 4 and making it resilient in its extended position, the risk of damage to the reflective disc is very small. The design with the aperture 12 and the prism 14, which receives light in the direction of the target, further achieves a desired balance between the brightness of the reflected sight image and the target itself. The possibility of achieving a suitable balance under different lighting conditions is also guaranteed by means of the LED 9 which can be switched between two brightnesses. By arranging a time relay, a long life of the battery is also ensured.
