- a cylinder bottom plug (76) is used, in which two detent balls (87) sit one behind the other in the radial transverse bore (82).
- the inner detent ball (87) is located in the notch (67), while the outer detent ball (87) rests against the annular spring (86).
- the annular spring (86) sits after FIG. 8 in a groove (83) which extends only over 270 degrees of the circumference of the flange (80).

Description
Die Erfindung betrifft ein Rückstoßdämpfersystem für eine Schulterstütze mit mindestens einem Führungssystem, mit mindestens einem Dämpferglied, mit mindestens einem Rückholsystem und mit mindestens einem Rastgesperre.The invention relates to a Rückstoßdämpfersystem for a shoulder rest with at least one guide system, with at least one damper member, with at least one return system and at least one locking mechanism.
Die Schulterstütze ist Teil des Hinterschaftes z.B. einer Jagdwaffe. Bei neuzeitlichen Waffen ist man bemüht, deren Gewicht so weit wie möglich zu reduzieren. Dies hat den Nachteil, dass dadurch der schussbedingte Rückstoß mit abnehmendem Waffengewicht zunimmt. Um diesen Rückstoß zu dämpfen, werden Dämpferglieder in die Schulterstütze integriert. Dazu wird die Schulterstütze im hinteren Bereich ca. normal zur Mittellinie des oder der Läufe aufgetrennt. Am freien Ende des verbleibenden Schaftteils wird eine schaftkappenartige Platte befestigt, die sich gegenüber dem verbleibenden Schaftteil über ein Feder-Dämpfersystem abstützt.The shoulder rest is part of the buttstock e.g. a hunting weapon. With modern weapons, one strives to reduce their weight as much as possible. This has the disadvantage that thereby the shot-related recoil increases with decreasing weapon weight. To dampen this recoil, damper links are integrated into the shoulder rest. For this purpose, the shoulder support is separated in the rear area approximately normal to the center line of the run or runs. At the free end of the remaining shaft part a shaft cap-like plate is fixed, which is supported relative to the remaining shaft part via a spring-damper system.

Diese Problemstellung wird mit den Merkmalen des Hauptanspruchs gelöst. Dazu besteht das Führungssystem aus einer in einem Grundkörper in Bohrungen mittels Führungsstangen geführten Stützplatte. Das Dämpferglied besteht aus einer hydraulischen Zylinder-Kolben-Einheit. Das Rückholsystem besteht aus mindestens einem mechanischen und/oder pneumatischen Federelement oder aus mindestens einem Federsystem. Die Zylinder-Kolben-Einheit hat eine Kolbenstange, die mit dem Zylinder oder einem Teil des Zylinders der Zylinder-Kolben-Einheit über ein Rast- oder Rastrichtgesperre in Wirkverbindung steht. Das Rast- oder Rastrichtgesperre sperrt die Kolbenstange in ihrer ausgefahrenen Position mit einer bestimmten oder einstellbaren Rastkraft.This problem is solved with the features of the main claim. For this purpose, the guide system consists of a guided in a base body in holes by means of guide rods support plate. The damper link consists of a hydraulic cylinder-piston unit. The return system consists of at least one mechanical and / or pneumatic spring element or at least one spring system. The cylinder-piston unit has a piston rod, which is in operative connection with the cylinder or a part of the cylinder of the cylinder-piston unit via a latching or Rastrichtgesperre. The locking or Rastrichtgesperre locks the piston rod in its extended position with a specific or adjustable latching force.
Mit der Erfindung wird ein Rückstoßdämpfersystem für eine Sport-, Jagd- oder Behördenwaffe geschaffen. Dazu wird die Schulterstütze in einen starren und einen beweglichen Teil aufgetrennt. Der bewegliche Teil, z.B. ein eine Schaftkappe tragendes Gestell oder Platte ist im Wesentlichen in Waffenlängsrichtung verschiebbar im starren Teil der Schulterstütze gelagert. Beim Auftreten eines schussbedingten Rückstoßes bewegen sich das starre und das bewegliche Teil auf einer kurzen Strecke aufeinander zu, wobei im Rückstoßdämpfersystem die kinetische Energie der Waffe in Federenergie und Wärme umgewandelt wird. Die Wärme entsteht in mindestens einem Dämpfer und die Federenergie wird im Rückholsystem kurzzeitig gespeichert. Durch die Dämpfung wird vom starren Schaftteil ca. die Hälfte der Stützkraft oder sogar noch weniger auf das bewegliche Schaftteil übertragen.The invention provides a recoil damper system for a sporting, hunting or governmental weapon. For this purpose, the shoulder rest is separated into a rigid and a movable part. The movable part, for example a frame or plate carrying a butt plate, is displaceably mounted in the rigid part of the shoulder rest substantially in the longitudinal direction of the weapon. The occurrence of a shot-related recoil move that rigid and the moving part on a short distance towards each other, wherein the recoil damper system, the kinetic energy of the weapon is converted into spring energy and heat. The heat is generated in at least one damper and the spring energy is temporarily stored in the return system. Due to the damping of the rigid shaft part about half of the supporting force or even less transmitted to the movable shaft part.
Das Rückstoßdämpfersystem umfasst ein zentrales Rastgesperre, das bis zu einer bestimmten Rastkraft verhindert, dass der Hub des Systems nicht schon beim Anlegen der Schulterstütze an die Schulter verbraucht wird. Das Rastgesperre sitzt ca. mittig in dem beim Schuss sich einstellenden Kraftfluss.The recoil damper system includes a central locking mechanism that prevents up to a certain locking force that the stroke of the system is not consumed when applying the shoulder rest to the shoulder. The locking mechanism is located approximately in the center of the force flow which occurs during firing.

Der Grundkörper (11) ist ein ovaler Körper mit einem zumindest annähernd gleicher Breite und Tiefe. Mittig an seiner vorderen Stirnseite (18), also an der Stirnseite, die in Richtung des Waffenlaufes zeigt, ist eine zentrale, zylinderrohrförmige Grundkörperverlängerung (28) angeformt. Der Durchmesser der Grundkörperverlängerung (28) entspricht der Breite des Grundkörpers (11).The base body (11) is an oval body with at least approximately the same width and depth. Centered on its front end face (18), that is on the front side, which points in the direction of the gun barrel, a central, cylindrical tube-shaped basic body extension (28) is formed. The diameter of the Base extension (28) corresponds to the width of the base body (11).
In seinen seitlichen Endbereichen hat der Grundkörper (11) je eine Führungsbohrung (12) in Form einer Durchgangsbohrung. Im Zentrum hat er eine Stufenbohrung (13), die von der vorderen Stirnseite (18) aus in den Grundkörper (11) eingearbeitet ist. Die Stufenbohrung (13) setzt sich aus der Zylinderbohrung (75), der Dichtungssitzbohrung (15) und der Kolbenstangenbohrung (14) zusammen, vgl.
Zwischen der Stufenbohrung (13) und je einer Führungsbohrung (12) ist in den Grundkörper (11) eine Federeinsenkung (16) von der Rückseite aus eingearbeitet. Im Grund einer jeden Federeinsenkung (16) ist eine Senkbohrung (27) angeordnet, vgl.
Nach
Auf der Bodenfläche (4) ist die z.B. 3 mm starke Basisplatte (30) angeordnet, vgl.
Der auf der Basisplatte (30) aufliegende Grundkörper (11) ragt genau so weit aus der Schulterstütze (1) heraus, dass eine auf der Stirnfläche (2) des Schafts (1) aufgeschraubte Anpassplatte (95) mit der Innenkontur ihrer zentralen Ausnehmung (96) bei seitlichem Spiel in Richtung der Seelenachse bündig und plan mit der Rückseite des Grundkörpers (11) abschließt. Die Anpassplatte (95) hat zwei jeweils mit Senkbohrungen ausgestattete Zentrierzapfen (97), die in die entsprechenden Zentriersenkungen (7) der Stirnfläche (2) passen. Mit Hilfe von in den Senkbohrungen sitzenden Senkholzschrauben (9) ist die Anpassplatte (95) fest mit dem Schaft (1) verbunden.The base body (11) which rests on the base plate (30) projects out of the shoulder support (1) to the extent that a fitting plate (95) screwed onto the end face (2) of the shaft (1) engages with the inner contour of its central recess (96 ) in lateral play in the direction of the axis of the soul flush and flush with the back of the main body (11). The adjusting plate (95) has two centering pins (97) each provided with countersunk holes, which fit into the corresponding centering countersinks (7) of the end face (2). With the aid of countersunk screws (9), which are located in the counterbores, the adapter plate (95) is firmly connected to the shaft (1).
Die Anpassplatte (95) hat einen breiten Rand, der jeweils durch z.B. spanabhebende Nacharbeit an die vorhandene Schaftform angepasst wird. Zur Schulterstütze (1) hin hat der Rand einen z.B. 7 mm breiten und 0,8 mm tiefen, umlaufenden Klemmabsatz (98). Auf der planen, zur Stirnfläche (2) parallelen Fläche des Klemmabsatzes (98) sind z.B. drei umlaufende Klemmstege (99) angeformt, vgl.
Parallel gegenüber der Rückseite des Grundkörpers (11) ist die Stützplatte (40) angeordnet. Die auf ihrer Rückseite z.B. ebene Platte hat auf ihrer dem Grundkörper (11) zugewandten Vorderseite mehrere Einsenkungen. Die tiefsten Einsenkungen sind die beiden Stangeneinsenkungen (42). In diese Einsenkungen münden koaxial die Befestigungsbohrungen (43). In den Stangeneinsenkungen (42) sind die Führungsstangen (47) mittels der Senkschrauben (49) formsteif befestigt. Die Führungsstangen (47) sitzen - als Teile des Führungssystems (10) - mit geringem Spiel geführt in den Führungsbohrungen (12) des Grundkörpers (11).Parallel to the back of the base body (11), the support plate (40) is arranged. The ones on their backside e.g. flat plate has on its the base body (11) facing the front of several depressions. The deepest depressions are the two bar sinkings (42). In these depressions coaxially open the mounting holes (43). In the rod depressions (42), the guide rods (47) by means of the countersunk screws (49) are rigidly attached. The guide rods (47) sit - as parts of the guide system (10) - guided with little play in the guide bores (12) of the base body (11).
Genau mittig zwischen den beiden Führungsstangen (47) ist die Kolbeneinheit (52) der Zylinder-Kolben-Einheit (51) mit der Stützplatte (40) verschraubt. Zwischen der Kolbeneinheit (52) und je einer Führungsstange (47) ist eine Federeinsenkung (41) angeordnet. Die Federeinsenkung (41) ist eine Stufenbohrung, die sich zur Rückseite der Stützplatte (40) maximal soweit verjüngt, dass noch der Schraubenkopf einer Schraube (29) hindurchpasst. Zwischen diesen Federeinsenkungen (41) und den jeweils gegenüber liegenden Federeinsenkungen (16) des Grundkörpers (11) sind die Schraubendruckfedern (91) zumindest annähernd formschlüssig und vorgespannt eingebaut.Exactly centrally between the two guide rods (47), the piston unit (52) of the cylinder-piston unit (51) with the support plate (40) is screwed. Between the piston unit (52) and a respective guide rod (47) a spring counterbore (41) is arranged. The spring depression (41) is a stepped bore which tapers to the rear of the support plate (40) to the maximum extent that even the screw head of a screw (29) passes through. Between these spring depressions (41) and the respectively opposite spring depressions (16) of the base body (11), the helical compression springs (91) are installed at least approximately positively and biased.
Ggf. kann auch eine zentrale Schraubendruckfeder um eine aus dem Grundkörper (11) herausragende Kolbenstange (71) angeordnet sein. Nach den
Die Stützplatte (40) hat eine großflächige Klemmplatteneinsenkung (45). Der Flächenbereich dieser Einsenkung liegt direkt gegenüber der Anpassplatte (95). Ihre Fläche entspricht auch großteils der Fläche der Anpassplatte (95). In der Klemmplatteneinsenkung (45) sitzt eine im Wesentlichen zu einem elliptischen Ring geformte ebene Klemmplatte (36), die mittels der Schrauben (38) fest gegen die Stützplatte (40) verspannt ist.The support plate (40) has a large-scale clamping plate recess (45). The area of this depression is directly opposite the adapter plate (95). Their surface also largely corresponds to the surface of the adapter plate (95). In the clamping plate recess (45) sits a substantially to an elliptical ring shaped planar clamping plate (36) which is clamped by means of screws (38) fixedly against the support plate (40).
Die Klemmplatte (36) hat einen umlaufenden Absatz (37) zur sicheren Anlage des Elastomerbalgs (100). Der ringartige Elastomerbalg (100), er kann auch ein gummierter Leinenbalg sein, hat einen c-förmigen Querschnitt, der aus einem mittigen Balghemd (101) und zwei randseitigen Klemmfalzen (102, 103) besteht, vgl.
Ggf. ist im Balghemd (101) ein sogenanntes modifiziertes Bunsenventil (105) integriert, vgl.
Das Bunsenventil (105) bleibt bei einem Überdruck im Balginnenraum (109) gasdicht verschlossen, da der auf die Balgwölbung (106) wirkende Gasdruck den Ventilschlitz (107) zudrückt. Herrscht im Balginnenraum (109) ein Unterdruck, öffnet das Ventil (105), indem der Ventilschlitz (107) - entgegen der inneren Elastomerkräfte der Balgwölbung (106) - aufklafft.The Bunsen valve (105) remains gas-tight in the event of an overpressure in the interior of the bellows (109), since the gas pressure acting on the bellows curvature (106) forces the valve slot (107) to be closed. If a negative pressure prevails in the interior of the bellows (109), the valve (105) opens, in that the valve slot (107) opens up, counter to the internal elastomer forces of the bellows curvature (106).
Nach den
Der Elastomerbalg (100) ist im Bereich der Innenseite des Klemmfalzes (102) mit der Klemmplatte (36) gasdicht verklebt. Zudem ist die Klemmplatte (36) mit der Stützplatte (40) verspannt. Der andere Klemmfalz (103) ist zwischen der Stirnseite (2) des Schafts (1) und der Anpassplatte (95) eingeklemmt. Die Klemmstege (99) der Anpassplatte (95) sichern dabei die Position des Klemmfalzes (103) sowie die Abdichtung des Balginnenraumes (109).The elastomer bellows (100) is glued gas-tight in the region of the inside of Klemmfalzes (102) with the clamping plate (36). In addition, the clamping plate (36) is clamped to the support plate (40). The other Klemmfalz (103) is clamped between the end face (2) of the shaft (1) and the matching plate (95). The clamping webs (99) of the adapter plate (95) thereby secure the position of the Klemmfalzes (103) and the sealing of the bellows interior (109).
Über die Rückseite der Stützplatte (40) ist eine gummielastische Schaftkappe (8) übergestülpt. Sie umgreift z.B. form- und kraftschlüssig den äußeren Rand der Stützplatte (40). Ggf. ist die Schaftkappe (8) auf der Stützplatte (40) auch aufgeklebt oder aufgeschäumt.Over the back of the support plate (40) a rubber-elastic butt plate (8) is slipped over. It encompasses, for example positive and non-positive, the outer edge of the support plate (40). Possibly. is the butt plate (8) on the support plate (40) also glued or foamed.
Zentral im Grundkörper (11) sitzt als Dämpferglied (50) die Zylinder-Kolben-Einheit (51), vgl.
Die beiden Kolbenstangen (61, 71) der Kolbeneinheit (52) haben jeweils einen Durchmesser von z.B. 6 mm. Die hintere Kolbenstange (71), die z.B. 11 mm länger ist als die vordere (61), hat stirnseitig eine Gewindebohrung (73), um die Kolbeneinheit (52) an der Stützplatte (40) befestigen zu können, vgl.
Die vordere Kolbenstange (61) hat z.B. zentral eine mehrfach gestufte Ventilbohrung (62). Die Ventilbohrung (62) endet hinter dem Kolben (53) im Bereich der hinteren Kolbenstange (71). Dort trifft sie senkrecht auf eine Querbohrung (72), vgl.
Die Ventilbohrung (62) weist an ihrem offenen Ende einen Innensechskant auf, der das Befestigen der Kolbeneinheit (52) an der Stützplatte (40) erleichtert. Im Bereich der Querbohrung (66) verengt sich die Ventilbohrung zur Ausbildung einer Drosselkante (63). Zwischen der Drosselkante (63) und dem Innensechskant ist auf einem mittleren Abschnitt in die Ventilbohrung (62) ein Feingewinde eingearbeitet. In diesem Feingewinde sitzt feinjustierbar ein Nadelventilglied (64).The valve bore (62) has at its open end a hexagon socket, which facilitates the attachment of the piston unit (52) on the support plate (40). In the region of the transverse bore (66), the valve bore narrows to form a throttle edge (63). Between the throttle edge (63) and the hexagon socket a fine thread is incorporated on a central portion in the valve bore (62). In this fine thread is finely adjustable a needle valve member (64).
Das Nadelventilglied (64) hat an seiner dem Kolben (53) zugewandten Seite seine Nadelspitze, über die es den die Querbohrungen (66, 72) durchströmenden Volumenstrom drosselt. Das andere Nadelventilgliedende weist - für die Verstellung des Nadelventilgliedes (64) - einen Innensechskant auf. Zwischen diesem Innensechskant und dem Feingewinde des Nadelventilgliedes (64) sitzt in einer Ringnut ein dichtender O-Ring (65).The needle valve member (64) has on its side facing the piston (53) its needle tip, via which it throttles the cross-flow through the holes (66, 72). The other needle valve member end has - for the adjustment of the needle valve member (64) - a hexagon socket. Between this hexagon socket and the fine thread of the needle valve member (64) sits in an annular groove a sealing O-ring (65).
Um den Rückhub der Stützplatte (40) - nach einem abgegebenen Schuss - zu beschleunigen, kann im Kolben (53) ein Rückströmventil (54) eingebaut werden, vgl.
Oberhalb der hinteren Kolbenstange (71) befindet sich eine Befüllbohrung (21), vgl.
Die Bewegung des Kolbens (53) in der Zylinderbohrung (75) ist nach hinten begrenzt durch den zwischen der Zylinderbohrung (75) und der Dichtungssitzbohrung (15) gelegenen Bohrungsbund (17), vgl.
Nach den
Nach vorn ist der Kolbenhub begrenzt durch einen eingeschraubten Zylinderbodenstopfen (76) oder durch die Anlage der Anpassplatte (95) an den Grundkörper (11). Die zentrale Bohrung des Zylinderbodenstopfens (76) ist gegenüber der vorderen Kolbenstange (61) mittels einer Dichtung, z.B. einer Doppellippendichtung (78), abgedichtet. Die vordere Kolbenstange (61) hat im Bereich ihres freien Endes eine umlaufende Rastkerbe (67).To the front of the piston stroke is limited by a screwed cylinder bottom plug (76) or by the system of the adjustment plate (95) to the base body (11). The central bore of the cylinder bottom plug (76) is opposite the front piston rod (61) by means of a seal, e.g. a double lip seal (78), sealed. The front piston rod (61) has a circumferential notch (67) in the region of its free end.
Nach den
Die meisten Teile des Rastgesperres sind in einem speziellen Zylinderbodenstopfen (76) integriert. Dazu hat der Zylinderbodenstopfen (76) nach
Im montierten Zustand nach den
Als Sperrstück des Rastgesperres (85) dient hier die vordere Kolbenstange (61). Bei gesperrtem Rastgesperre (85) greift in die Rastkerbe (67) als Sperrer eine Rastkugel (87) ein. Da das Rastgesperre (85) nur in eine Richtung zu sperren braucht, kann es auch als Rastrichtgesperre gestaltet sein. Dazu kann z.B. die linke Flanke der Rastkerbe (67) weggelassen werden.As a locking piece of Rastgesperres (85) here serves the front piston rod (61). When the locking mechanism (85) is locked, a detent ball (87) engages in the detent notch (67) as a detent. Since the locking mechanism (85) only needs to lock in one direction, it can also be designed as Rastrichtgesperre. For this, e.g. the left flank of the notch (67) are omitted.
Nach den
Die gezeigten Zylinderbodenstopfen (76) weisen jeweils nur ein Rastgesperre (85) auf. Es ist denkbar, dass an der Kolbenstange (61, 71) ein oder zwei weitere Rastgesperre zusätzlich angeordnet werden.The cylinder bottom plugs (76) shown each have only one latching mechanism (85). It is conceivable that one or two further locking mechanism are additionally arranged on the piston rod (61, 71).
Die Montage des Rückstoßdämpfersystems erfolgt in sieben Schritten. In einem ersten Schritt werden an der Schulterstütze (1) alle erforderlichen Holzbearbeitungen durchgeführt. Der Schaft wird plan überarbeitet und die erforderlichen Ausnehmungen (3, 5, 6, 7) werden herausgearbeitet, vgl.
Bei der Benutzung des Rückstoßdämpfersystems durch den Schützen soll die mit der Schaftkappe (8) ausgestattete Stützplatte (40) in ihrer unbetätigten Endlage lösbar verrastet sein, um die Schulterstütze (1) - beim Zielen - zunächst unnachgiebig zu arretieren. Beim Abgeben eines Schusses wird rückstoßbedingt als Erstes die Rastkraft des Rastgesperres (85) überwunden. Erst hiernach kommt die hydraulische Dämpfung zur Wirkung. Durch die Relativbewegung zwischen dem Kolben (53) und dem Zylinder (74), im Ausführungsbeispiel sind es 12 mm, wird das Hydrauliköl vom Zylinderraum (69) in den Zylinderraum (79) gedrosselt und dämpfend umgepumpt. Hierbei werden die beiden Schraubendruckfedern (91) weiter gespannt. Gleichzeitig wird die im Balginnenraum (109) gasdicht oder zumindest nahezu gasdicht gespeicherte Luft komprimiert. Folglich liegt hier ein Federsystem aus z.B. zwei mechanischen (91) und einem pneumatischen Federelement (100, 109) vor.When the recoil damper system is used by the shooter, the support plate (40) provided with the butt plate (8) should be releasably locked in their unactuated end position to the shoulder support (1) - when aiming - initially unyielding to lock. When issuing a shot, the detent force of the locking mechanism (85) is first overcome by recoil. Only then does the hydraulic damping come into effect. Due to the relative movement between the piston (53) and the cylinder (74), in the exemplary embodiment is 12 mm, the hydraulic oil from the cylinder chamber (69) in the cylinder chamber (79) throttled and pumped around damping. Here, the two helical compression springs (91) are stretched further. At the same time in the bellows interior (109) is compressed gas-tight or at least almost gas-tight stored air. Consequently, here is a spring system of, for example, two mechanical (91) and a pneumatic spring element (100, 109) before.
Nachdem am Ende der Eintauchbewegung die Stützplatte (40) an der Anpassplatte (95) anliegt, wird die Bewegungsrichtung umgekehrt. Die Schraubendruckfedern (91) setzen ihre gespeicherte Energie frei, indem sie die Stützplatte (40) und die Kolbeneinheit (52) wieder in ihre Ausgangslage schieben. Letztere ist erreicht, wenn der Kolben (53) am Bohrungsbund (17) anliegt und die Rastkugeln (87) wieder in der Rastkerbe (67) einrasten. Sollte der Elastomerbalg (100) bei der Kompression Luft verloren haben, so wird der Luftverlust durch das kurzzeitige Öffnen des Bunsenventils (105) ausgeglichen.After the support plate (40) abuts against the matching plate (95) at the end of the immersion movement, the direction of movement is reversed. The helical compression springs (91) release their stored energy by pushing the support plate (40) and the piston unit (52) back into their original position. The latter is achieved when the piston (53) rests against the bore collar (17) and the locking balls (87) engage again in the latching notch (67). If the elastomer bellows (100) have lost air during compression, the air loss is compensated by the momentary opening of the Bunsen valve (105).
