Description

Oppfinnelsen angår et selvanvisende skytemål slik det The invention relates to a self-indicating shooting target such as that

er beskrevet i kravets innledning. is described in the introduction of the requirement.

Tidligere kjente selvanvisende skyteskiver som skytemål har anviserarmer som ved treff mot skiven svinges ut for anvisning. Disse armer og anordninger for bevegelsen kan lett ødelegges og mekanismene selv er ikke alltid pålitelige over lengre tid. Formerly known self-indicating shooting targets as targets have indicator arms which, when hitting the target, are swung out for guidance. These arms and devices for the movement can be easily destroyed and the mechanisms themselves are not always reliable over a long period of time.

En selvanvisende skyteskive er også kjent hvor selve skyteskiven ved treff dreies en bestemt vinkel og dreies til-bake ved et ytterligere treff. En slik skive er beskrevet i NO 84 785. A self-directing shooting disc is also known, where the shooting disc itself is turned a certain angle on impact and is turned back on a further hit. Such a disc is described in NO 84 785.

Skyteskiven ifølge det nevnte patent danner en meka-nisme som er forholdsvis komplisert og som også derigjennom kan bli upålitelig på grunn av slitasje etc. The firing disc according to the aforementioned patent forms a mechanism which is relatively complicated and which can also become unreliable due to wear etc.

Det er et formål med oppfinnelsen å frembringe en skyteskive som er enkel i sin konstruksjon og som også ved lengre tids bruk opprettholder sin funksjon, nemlig å anvise treff mot skyteskiven ved en vinkeldreining av selve skiven. It is a purpose of the invention to produce a shooting disc which is simple in its construction and which also maintains its function during prolonged use, namely to indicate a hit against the shooting disc by an angular rotation of the disc itself.

Dette mål tilfredsstilles ved oppfinnelsen som er beskrevet ved kravenes karakteristiske trekk. This objective is satisfied by the invention which is described by the characteristic features of the claims.

Selve skyteskiven kan ha et kvadratisk eller rektangu-lært utseende for således ved skivens endrede stilling å anvise treff mot kulen. På den annen side kan skiven være sirkelrund eller ha en annen fasong, men ha et merke på skiven som tyde-lig tilkjennegir at skiven dreies til den ene eller annen side. The shooting disc itself can have a square or rectangular appearance, so that when the disc's position is changed, it indicates a hit against the ball. On the other hand, the disc may be circular or have a different shape, but have a mark on the disc which clearly indicates that the disc is turned to one side or the other.

På tegningen viser figur 1 skyteskiven sett fra siden In the drawing, Figure 1 shows the shooting disc seen from the side

i hvilestilling, figur 2 viser skyteskiven i labil stilling under bevegelse mellom ytterstillingene, figur 3 viser et snitt langs III-III på figur 1, med stiplet omriss av skyteskiven og figur 4 viser et riss langs IV-IV på figur 2 med skyteskiven i midtstilling. in rest position, figure 2 shows the target in a labile position during movement between the extreme positions, figure 3 shows a section along III-III in figure 1, with a dashed outline of the target and figure 4 shows a view along IV-IV in figure 2 with the target in the middle position .

Skyteskiven 1 er opplagret for frem- og tilbåkegående bevegelse på en bærearm 2 ved hjelp av en glidehylse 11, idet det fra glidehylsen 11 til skyteskiven er anordnet støttestag 10. The shooting disc 1 is supported for reciprocating movement on a support arm 2 by means of a sliding sleeve 11, with a support rod 10 being arranged from the sliding sleeve 11 to the shooting disc.

På skyteskivens 1 bakside, mot bærearmen 2, er en bolt On the back of the firing disc 1, against the support arm 2, is a bolt

3 festet som er ført gjennom en pendelarm 6. Pendelarmen 6 3 attached which is passed through a pendulum arm 6. The pendulum arm 6

er dreibart opplagret i opplagringen 8 på bærearmen 2. En av-standshylse 4 ligger an mot pendelarmen 6 slik at en bakover- is rotatably supported in the bearing 8 on the support arm 2. A spacer sleeve 4 rests against the pendulum arm 6 so that a backward

gående bevegelse av skyteskiven 1 umiddelbart medfører en bevegelse av pendelarmen 6 via hylsen 4. En mutter 5 er festet til bolten på baksiden av pendelarmen 6 for sikring av bolten i pendelarmen. walking movement of the firing disc 1 immediately causes a movement of the pendulum arm 6 via the sleeve 4. A nut 5 is attached to the bolt on the back of the pendulum arm 6 to secure the bolt in the pendulum arm.

Til skivens 1 bakside er festet en anleggsflate 7 i rett vinkel til et plan gjennom bolten og skyteskivens 1 tyngdepunkt. Skyteskivens tyngdepunkt ligger over boltens 3 senter-akse slik at skyteskiven således er labilt opphengt og hindres i å dreie til stabil stilling ved at en anleggsplate 9 er festet til pendelarmen 6 og ligger an mot anleggsflaten 7 med horisontale anlegg 12, hhv. 13. A contact surface 7 is attached to the back of the disc 1 at right angles to a plane through the bolt and the center of gravity of the shooting disc 1. The shooting disc's center of gravity lies above the center axis of the bolt 3 so that the shooting disc is thus labilely suspended and is prevented from turning to a stable position by the fact that a contact plate 9 is attached to the pendulum arm 6 and rests against the contact surface 7 with horizontal contacts 12, respectively. 13.

Skyteskiven har festeanordninger 14 anordnet på bærearmen 2 for feste av skyteskiven til et underlag. The shooting disc has fastening devices 14 arranged on the support arm 2 for attaching the shooting disc to a base.

Når en kule treffer skyteskiven 1 vil skyteskiven 1 beveges mot høyre på tegningen slik at hylsen 4 presser pendelarmen 6 også mot høyre, noe som resulterer i at anleggsplaten 9 blir presset nedover og det horisontale anlegg 12 eller 13 vil med en hurtig bevegelse bli slått ned mot anleggsflaten 7 som er festet til skiven 1. Dette slag vil resultere i at anleggsflaten 7 med skyteskiven 1 vil får et dreiemoment om-kring bolten 3 slik at skyteskivens 1 tyngdepunkt beveges forbi det vertikale plan gjennom bolten 3 og skyteskiven 1 selv vil fortsette bevegelsen inntil det horisontale anlegg 13, hhv. 12 kommer til anlegg mot anleggsflaten 7. When a bullet hits the firing disc 1, the firing disc 1 will be moved to the right in the drawing so that the sleeve 4 presses the pendulum arm 6 also to the right, which results in the support plate 9 being pressed downwards and the horizontal support 12 or 13 will be knocked down with a rapid movement against the contact surface 7 which is attached to the disc 1. This impact will result in the contact surface 7 with the shooting disc 1 receiving a torque around the bolt 3 so that the center of gravity of the shooting disc 1 is moved past the vertical plane through the bolt 3 and the shooting disc 1 itself will continue the movement until the horizontal facility 13, respectively 12 comes to construction against construction surface 7.

Parametre som er avgjørende for at skyteskiven 1 skal kunne beveges forbi sin labile stilling på grunnlag av et skudd mot skiven, er avstanden mellom boltens 3 dreieakse og skivens tyngdepunkt, skivens totale vekt, den horisontale avstand mellom anleggsplatens 9 forkant og opplagringen 8, avstanden mellom de horisontale anlegg 12 og 13 samt disses avstand til an-leggsf laten 7, i tillegg til avstanden mellom anleggsflaten 7 og boltens 3 akse. Parameters that are decisive for the firing disc 1 to be able to be moved beyond its unstable position on the basis of a shot against the disc are the distance between the pivot axis of the bolt 3 and the center of gravity of the disc, the total weight of the disc, the horizontal distance between the front edge of the base plate 9 and the support 8, the distance between the horizontal supports 12 and 13 and their distance to the contact surface 7, in addition to the distance between the contact surface 7 and the bolt's 3 axis.

Disse parametre kan avstemmes overfor hverandre for å sikre at skyteskiven 1 anviser treff ved dreining under ulike skyteforhold, eksempelvis avstander, våpentype og patronlad-ninger. These parameters can be adjusted against each other to ensure that the firing disc 1 indicates a hit when turning under different shooting conditions, for example distances, weapon type and cartridge loads.

Skyteskiven i henhold til oppfinnelsen er enkel i sin konstruksjon, robust og pålitelig under bruk og lett anvende-lige under ulike forhold. The shooting disc according to the invention is simple in its construction, robust and reliable during use and easily applicable under various conditions.
