Den foreliggende opfindelse angår et rekyl dæmpende stativ til et manuelt betjent automatvåben som angivet i indledningen til patentkravet.The present invention relates to a recoil damping rack for a manually operated automatic weapon as set forth in the preamble to the claim.

Fra CH patentskrift nr. 169 746 kendes et rekyl dæmpende stativ til 5 et manuelt betjent automatvåben, hvor den bevægelige del af våbenet afstøttes ved, at to tappe på våbenet holdes og føres på længdeforskydelig måde i kopagtigt udformede gaffelender af en svingarm. I de kopformede dele af svingarmen er der arrangeret bremsefjedre og gummidæmpere til at optage stødbevægelserne. Svingarmen er en del af en vugge, som kan høj -10 deindstilles ved svingning omkring to tappe, og de støddæmpende fjedre er arrangeret symmetrisk omkring våbenets centerlinie og i retning imod aksen for højdeindstil 1ingstappene. Våbenet afstøttes bagtil ved et glide! eje i forbindelse med en føringsklo. Skriftet viser ikke nærmere detaljer om føringen af våbenet under rekyl bevægelserne, og det viser in-15 tet om sigtemidler.From CH Patent No. 169,746, a recoil damping rack for 5 is known as a manually operated automatic weapon, wherein the movable portion of the weapon is supported by two pins on the weapon being held and guided in a longitudinally slidable manner in cup-shaped fork ends of a swingarm. In the cup-shaped parts of the swing arm, brake springs and rubber dampers are arranged to accommodate the shock movements. The pivot arm is part of a cradle which can be set high -10 by pivoting about two pins, and the shock absorbing springs are arranged symmetrically around the center line of the weapon and towards the axis of the height adjustment pins. The weapon is backed by a slide! own in connection with a driving claw. The script does not show further details on the guiding of the weapon during the recoil movements, and it does not show the intent of the aiming means.

Ifølge opfindelsen tilvejebringes et rekyldæmpende stativ af den indledningsvis angivne art, hvilket stativ er ejendommeligt ved, at det omfatter en anden vugge arrangeret inden for den første vugge og indrettet til fast at optage våbenet på en sådan måde, at det kan glide i for-20 hold til den første vugge, idet støddæmperne virker imellem den første og den anden vugge, og idet der er arrangeret et sigte for våbenet på den bageste del af den første vugge.According to the invention there is provided a recoil damping rack of the kind initially provided, which is characterized in that it comprises a second cradle arranged within the first cradle and arranged to firmly receive the weapon in such a way that it can slide in the front cradle. hold to the first cradle, the shock absorbers acting between the first and second cradles, and having a sieve for the weapon arranged on the rear of the first cradle.

Herved opnås en let konstruktion af stativet samtidig med en meget præcis føring af våbenet kombineret med en dæmpning af rekyl kræfterne af 25 størrelsesordenen 80-90%. Endvidere opnås der et sigte, som virker meget hensigtsmæssigt, og som navnlig gør, at sigtet bedre kan opretholdes præcist - også efter affyring af flere skud.This results in a lightweight construction of the stand at the same time as a very precise guiding of the weapon combined with a damping of the recoil forces of the order of 80-90%. Furthermore, a sieve is obtained which seems very suitable, and in particular means that the sieve can be better maintained accurately - even after firing multiple shots.

Opfindelsen vil fremgå nærmere af den følgende detaljerede beskrivelse, som gives under henvisning til tegningen, hvor 30 fig. 1 viser et sidebillede af det rekyldæmpende stativ ifølge opfindelsen med våben installeret, fig. 2 er et planbillede af stativet fra fig. 1, fig. 3 er et længdesnit gennem støddæmperen i større målestok, og 35 fig. 4 er et planbillede af den forreste del af vuggen i samme målestok som fig. 3.The invention will become more apparent from the following detailed description which is given with reference to the drawing, in which: FIG. 1 is a side view of the recoil damping rack according to the invention with weapons installed; FIG. 2 is a plan view of the frame of FIG. 1, FIG. 3 is a longitudinal section through the shock absorber on a larger scale; and FIG. 4 is a plan view of the front of the cradle on the same scale as FIG.

2 en svinggaffel 3, der er drejeligt fastgjort til et ikke nærmere vist fundament, såsom en trefod. Gaflen 3 understøtter drejbart en ydre vugge 1 ved hjælp af to lejetappe 9 arrangeret symmetrisk og i samme plan som vuggens 1 centerlinie 8, således at lejetappenes 9 akser har en fælles 5 centerlinie, som forløber i plan med og vinkelret på våbenets centerlinie 7. Den ydre vugge 1 kah derfor dreje"om lejetappene 9 og indtage den ønskede vinkel af centerlinien 7 i forhold til horisontal pi anen. Ved svinggaflens 3 understøtning på trefoden kan den ydre vugge 1 drejes omkring en vertikal akse i forhold til trefoden.2 is a pivot fork 3 which is pivotally attached to an unspecified foundation, such as a tripod. The fork 3 pivotally supports an outer cradle 1 by means of two bearing pins 9 arranged symmetrically and in the same plane as the center line 8 of the cradle 1, so that the axes of the bearing pins 9 have a common 5 center line extending in plane with and perpendicular to the center line of the weapon 7. outer cradle 1 may therefore rotate about the bearing pins 9 and take the desired angle of the center line 7 relative to the horizontal pivot. With the support of the pivot fork 3 on the tripod, the outer cradle 1 can be rotated about a vertical axis with respect to the tripod.

10 En indre vugge 2 er arrangeret forskydeligt i den ydre vugge 1 ved forreste og bageste gi ideføringer. Den forreste gi ideføring er vist i fig. 3 og den omfatter en bolt fastgjort til den ydre vugge 1, så den rager ud gennem en spalte 10 i den indre vugge på en sådan måde, at den indre vugge kan forskydes i våbenets længderetning over en begrænset af-15 stand svarende til spaltens længde, idet der er arrangeret formstofmate-riale 13, 14 mellem den indre og den ydre vugge og imellem en spændeskive under boltens hoved og indervuggen 2. Der er desuden arrangeret glide! ejer 11 og 12 imellem den indre og den ydre vugge, i det mindste i den ene side. På denne måde opnås der en meget nøjagtig føring af den 20 frem- og tilbagegående bevægelse for den indre vugge 2 i forhold til den ydre vugge 1.An inner cradle 2 is displaceably arranged in the outer cradle 1 at the front and rear guides. The front guide is shown in FIG. 3, and includes a bolt attached to the outer cradle 1 so that it protrudes through a slot 10 in the inner cradle in such a way that the inner cradle can be displaced longitudinally of the weapon over a limited distance corresponding to the length of the slot , in which plastic material 13, 14 is arranged between the inner and the outer cradle and between a washer under the bolt head and the inner cradle 2. In addition, slides are arranged! owns 11 and 12 between the inner and outer cradle, at least on one side. In this way, a very accurate movement of the reciprocating movement of the inner cradle 2 relative to the outer cradle 1 is obtained.

To støddæmpere 4 og 5 arrangeret symmetrisk omkring våbenets centerlinie 7 forbinder den indre og den ydre vugge, idet støddæmperne begge er arrangeret i samme plan som centerlinien og de to lejetappe 9. De 25 kræfter, som overføres til stativet ved affyring af våbenet, overføres derved langs centerlinien 7 igennem de to støddæmpere 4 og 5 til de to tappe 9, hvorved svinggaflen 3 optager den rest af rekyl kraften, som ikke er absorberet i støddæmperne 4 og 5. Da støddæmperne og tappene 9 er arrangeret i samme plan som centerlinien 7, bliver der ikke overført no-30 gen momentkræfter fra rekylen til stativet, og stativet holder således våbenets sigtelinie, også efter affyring af et skud. Et sigte 6 er arrangeret på den bageste del af den ydre vugge 1.Two shock absorbers 4 and 5 arranged symmetrically around the center line of the weapon 7 connect the inner and outer cradle, the shock absorbers being both arranged in the same plane as the center line and the two bearing pins 9. The 25 forces transmitted to the rack by the firing of the weapon are thereby transferred. along the center line 7 through the two shock absorbers 4 and 5 to the two pins 9, whereby the pivot fork 3 absorbs the rest of the recoil force which is not absorbed in the shock absorbers 4 and 5. Since the shock absorbers and pins 9 are arranged in the same plane as the center line 7, no no 30 torque forces are transferred from the recoil to the rack, and the rack thus holds the line of sight of the weapon, even after firing a shot. A sieve 6 is arranged on the rear of the outer cradle 1.

Støddæmperne 4 og 5 er vist i fig. 3 og 4 og hver af dem omfatter en skruefjeder 16, der sammentrykkes af rekyl kraften, idet den inderste 35 vugge 2 derved forskydes bagud i forhold til den yderste vugge 1. Skruefjederen 16 fører derefter den inderste vugge 2 tilbage til udgangspositionen. Skruefjederen 16 er arrangeret inden i og er i anlæg imod bunden af en cylinder fastgjort til den ydre vugge 1, mens fjederens 16 andenShock absorbers 4 and 5 are shown in FIG. 3 and 4 and each of them comprises a coil spring 16 which is compressed by the recoil force, the inner cradle 2 being thereby displaced rearwardly relative to the outer cradle 1. The coil spring 16 then returns the inner cradle 2 to its initial position. The coil spring 16 is arranged inside and abuts against the bottom of a cylinder attached to the outer cradle 1, while the second of the spring 16
