  • a bolt-action rifle is one of the bolt-action weapons.
  • repeating weapons are "firearms in which, after a shot has been fired, ammunition is reloaded from a magazine into the cartridge chamber via a mechanism that can be operated by hand”.
  • Bolt-action weapons also include bolt-action rifles or bolt-action rifles.
  • Bolt action breeches regularly include a bolt handle or bolt action lever and a safety device.
  • the fuse serves to prevent an unwanted shot being fired.
  • cylinder closures comprise at least one locking lug, a cartridge extractor, a case and a firing pin with a firing pin spring.
  • the straight pull bolt comprises a bolt sleeve which is arranged in a bolt housing, the bolt sleeve being movable back and forth by means of a bolt handle.
  • a locking head with locking lugs is rotatably mounted in the locking sleeve by means of a shaft.
  • the breech case includes a firing pin which is acted upon by a firing pin spring.
  • the locking sleeve serves to generate a rotary impulse in order to screw the locking head in the locking position into the locking chamber corresponding to the locking lugs.
  • the straight-pull closure has a locking lever as a locking means, which is mounted in a tiltable manner on the locking sleeve.
  • the locking lever prevents relative movement between the breech case and the breech head.
  • the locking lever is acted upon by a spring in the locking direction.
  • the DE 196 08 872 C1 describes a locking device for bolt-action rifles.
  • the locking device has a bolt lever which can be latched in the foremost position and which interacts with a locking device. Furthermore, the locking device comprises a firing pin which can be locked in a first rear position by means of a locking device.
  • the bolt lever can be set in different positions in one straight movement.
  • the closure device comprises an external sleeve arranged in one chamber is.
  • the chamber has a bolt head.
  • a control piece is slidably mounted within the chamber.
  • a bolt lever is connected to the control piece so that moving the bolt lever backwards unlocks the bolt head and locks it when the bolt is advanced.
  • the bolt head is rotated by moving the control piece axially.
  • the straight-pull closure comprises a closure sleeve that is mounted such that it can rotate about a longitudinal axis.
  • a control cam extending obliquely to the longitudinal axis is introduced into the inner casing of the closure sleeve in the rear area.
  • the straight-pull lock comprises a connecting link with a pin attached to the front end, which is in engagement with the cam.
  • the U.S.A. 4,672,762 shows a device for a bolt-action rifle with a cylinder chamber mechanism with a receiver and a chamber.
  • a lockable closure is arranged in the cylinder chamber mechanism. In a locked position, the closure prevents a chamber head from being rotated from its position in engagement with an extension of the receiver or a detent in the receiver. The rifle cannot be opened in the locked position, ie the chamber in the receiver cannot be moved backwards.
  • one object of the present invention is to improve a straight-pull closure so that it can be used more easily and more securely by a user in a repeating weapon.
  • a further object is to enable a simple, inexpensive construction of a straight-pull closure. It is also an object of the invention to provide a bolt-action weapon with a straight-pull lock with an integrated manual cocking system, in which the firing pin spring is cocked manually before the shot is fired and at the same time as the cartridge is changed.
  • the straight pull action according to the invention for repeating weapons comprises a locking sleeve, a first gear component, a second gear component and a repeating lever.
  • the closure sleeve is a cylindrical hollow body that can be rotated about a longitudinal axis.
  • the longitudinal axis is parallel, preferably coaxial, to the barrel axis of the weapon, with the muzzle of the barrel being to be regarded as lying at the front for the following considerations.
  • a locking head is arranged at the front end of the locking sleeve.
  • the first gear component is arranged on the locking sleeve in a rotationally fixed manner.
  • the second gear component is at an angle, preferably perpendicular, to the first gear component.
  • the two gear components are in mesh with one another, so that a rotary motion about a first axis transverse to the barrel axis can be transferred into a rotary motion about a second axis parallel to the barrel axis.
  • the repeating lever which can also be referred to as the bolt handle, is connected to the second gear component.
  • the bolt action lever is an im Area of an axis of rotation of the second transmission component arranged lever.
  • the repeating lever can be rotated at least in sections about the common axis of rotation.
  • a first functional position is the locking position, in which the breech head is locked or brought into a locked position by moving or rotating the repeating lever into the locking position, usually caused by a user/gun handler.
  • the movement of the repeating lever transfers the rotary motion about the first axis transversely to the barrel axis via the two gear components into the rotary motion about the second axis parallel to the barrel axis, and the first gear component rotates the bolt case with the bolt head around the longitudinal axis, so that the bolt head is screwed into the locked position.
  • the locking of the breech head is necessary so that the pressure generated when a shot is fired does not cause the breech case with the components arranged on it to move in the axial direction.
  • the second functional position is the unlocking position, with the bolt head being unlocked or brought into an unlocked position by moving or turning the repeating lever into the unlocking position, preferably by the user.
  • the movement of the repeating lever transfers the rotary movement about the first axis transversely to the barrel axis via the two gear components into the rotary movement about the second axis parallel to the barrel axis and the breechblock with the breech head rotates about the longitudinal axis of the breechblock via the first gear component, so that the locking head is screwed into the unlocked position.
  • the rotation to the unlocked position and the rotation in the locking position is opposite movements, so that one rotation is in the positive direction of rotation and the other rotation is in the negative direction of rotation.
  • the turning or rotation of the repeating lever about the axis of rotation takes place in a vertical plane when the weapon is in the usual firing direction, ie with the barrel axis lying essentially in the horizontal direction. Furthermore, the repeating lever and with it the gear components, the breech case and the breech head can be moved back and forth or to and fro in the axial direction, so that a cartridge case can be ejected and a cartridge can be inserted into a cartridge chamber.
  • a significant advantage of this structural design of the straight-pull bolt is that the weapon operator can move the bolt-action lever back and forth on a continuous path of movement when repeating. Instead, in the case of previously known repeating weapons, at least two discontinuously composed movement sections are regularly required.
  • the straight-pull bolt according to the present invention requires only two moving components for repeating, which brings further advantages in terms of functionality and safety, because fewer components lead to less play, less friction and increased operational reliability -Ness. Another advantage can be seen in the conversion of movement when repeating for the actuation of the breech. By dispensing with the translational movement, the present straight-pull closure requires only a single conversion of movement, which results in better power transmission and less wear.
  • the first transmission component is a first bevel gear, which preferably has a cylindrical extension at its first end that rests on the closure sleeve. At its second end, which is opposite the first end, the first bevel gear preferably has circumferential teeth.
  • the first bevel gear particularly preferably has teeth in one section. The teeth together form a ring gear or a ring gear section.
  • the first transmission component is, for example, a cam with a recess in which the second transmission component engages.
  • the transmission components can be replaced by other components known per se, which enable the aforementioned deflection of the movements/rotations.
  • the first transmission component preferably has a through hole along the longitudinal axis of the first transmission component.
  • sections of the first transmission component are coaxially surrounded by the closure sleeve.
  • the second transmission component is a second bevel gear, which preferably has peripheral teeth, which mesh with the teeth of the first bevel gear.
  • the teeth of the second bevel gear are particularly preferably formed on one section.
  • the teeth of the second bevel gear form a ring gear and are preferably predominantly on a side face of the bevel gear.
  • the second bevel gear can also be referred to as the drive bevel gear, while the first bevel gear forms the driven bevel gear.
  • the repeating lever is preferably arranged on the side face of the second bevel gear opposite the teeth.
  • the second gear component has a shape which can be rotated about the axis of rotation with the repeating lever, with an elevation being located on a side facing away from the repeating lever, which engages in the complementary recess of the first gear component.
  • the elevation can be a pin, for example.
  • This straight-pull bolt is that a movement in a first plane can be easily converted into a movement in a second plane, so that a longitudinal displacement of the repeating lever parallel to the gun barrel or the weapon housing is converted into a rotational movement of the receiver with the bolt head within the housing.
  • the straight-pull breech also includes a firing pin and a firing pin spring.
  • the firing pin is arranged coaxially to the breech case and has a firing pin collar in its front area.
  • the firing pin spring is arranged coaxially on the firing pin and preferably bears with one end directly against the firing pin collar and with the other end preferably against a clamping sleeve.
  • the firing pin is movable along the longitudinal axis of the breech case.
  • the straight-pull lock also preferably includes the clamping sleeve arranged on the first transmission component and a connecting element.
  • the collet and the connecting element are positioned in an axially rear region of the firing pin, Both the clamping sleeve and the connecting element preferably have a through hole through which the firing pin is guided and the clamping sleeve and connecting element are therefore arranged one behind the other.
  • the connecting element which can also be referred to as a latching flag, is arranged on the firing pin in a rotationally fixed manner.
  • the second gear component has, on its surface opposite the repeating lever, two spaced-apart pins that extend along the axis of rotation.
  • the pins extend parallel to the axis of rotation of the second gear component, preferably 90 degrees to the second gear component.
  • the pegs can be cylindrical elevations, alternatively the pegs can be an elevation of any shape.
  • the first pin is preferably in contact with the clamping sleeve and the connecting element. As already described, when the repeating lever rotates into the closed position, a movement is transferred to the second gear component with the pins arranged thereon. The movement of the first pin results in a simultaneous longitudinal movement of the firing pin, the connecting element and the collet along the longitudinal axis.
  • the straight-pull bolt preferably comprises a sear, against which the connecting element comes into contact as soon as the repeating lever is rotated into the bolted position. Because the connecting element rests against the sear, the connecting element is prevented from moving further along the longitudinal axis, so that the distance between the firing pin collar and the clamping sleeve is reduced, as a result the firing pin spring is cocked. Cocking of the firing pin spring is required to initiate a shot.
  • the straight-pull bolt also includes a lifting element, which is guided into a recess in the locking sleeve by means of the second pin of the second gear component when the repeating lever is rotated into the unlocking position, so that a rotary movement of the locking sleeve and thus the two gear components is prevented.
  • the excavation element preferably comprises an excavation pin and a forced excavation.
  • a spring is preferably arranged between the excavation pin and the forced excavation, so that the forced excavation is resiliently mounted on the excavation pin.
  • the repeating lever moves from the unlocked position together with the gear components, the locking sleeve and the locking head in a substantially axial direction, initially backwards and then forwards, the excavation element comes into contact with a component and is pushed out of the recess of the locking sleeve.
  • the transmission components can be rotated again with the locking sleeve.
  • the component on which the excavation element comes to rest can be, for example, a sleeve or a rear end of a gun barrel.
  • the lifting pin particularly preferably comes into contact with the component when the repeating lever moves backwards in the unlocked position.
  • the straight-pull bolt also includes a safety element for blocking or releasing a rotary movement of the repeating lever.
  • the safety element can be locked in different positions. In a deactivated position, the securing element engages in a groove of the second transmission component, so that a rotational movement of the second transmission component and thus a movement of the elements connected to the second transmission component are blocked. The deactivation position prevents an unintentional shot being fired or the unintentional cocking of the firing pin spring.
  • the deactivation position of the safety element the repeating lever is securely in a functional position between the unlocked position and the locked position. In this third position, the repeating lever cannot be moved into either of the other two positions. In an activation position of the securing element, the securing element does not act on the second transmission component, so that the latter can be rotated and is not blocked. Other positions in which the security element can be fixed are conceivable.
  • the securing element preferably consists of a securing slide and a latching element, between which a spring is stretched and which interact.
  • the locking element can also be referred to as a chamber lock.
  • an elevation in the form of a wart is formed on the closure head.
  • Three lugs are particularly preferably formed on the closure head.

  • the holding element serves to hold the closure sleeve so that it is not twisted during a movement along the longitudinal axis.
  • the locking head preferably comes to rest on a plate, alternatively preferably in a recess with its boss, so that the maximum opening of the locking sleeve is limited.
  • the straight-pull closure comprises a closure sleeve 01, which can be rotated about a longitudinal axis 02.

If the repeating lever 09 is moved back into the intermediate position B or the unlocking position C after the shot has been fired, the second latching arm 41 of the latching element 17 slides out of the recess 43 of the latching lug 21.
  • the locking element 17 remains in position D and blocks the return movement of the repeating lever 09 in the intermediate position B or, after actuating the safety slide 16, reaches the unlocking position C.
  • FIG 8 shows a side view of the straight-pull closure according to FIG 1 in the sleeve 33.
  • a lock holder 44 prevents the twisting of the straight-pull lock in the sleeve 33 .
  • the lock holder 44 is arranged in a bore on the underside of the sleeve 33 and engages with the breech sleeve 01 in a longitudinal groove (not shown) of the breech sleeve 01 during the forwards and backwards movement of the straight-pull bolt or the repeating lever 09, so that it does not overturn its longitudinal axis can be rotated.
  • the maximum opening position of the straight-pull closure is limited by a plate 46.
  • the plate 46 is arranged in a rear area of the sleeve 33 .
  • the lock head 03 comes to rest with its mastoids 04 on the plate 46 .
  • FIG 9 shows a detailed view of a repeating weapon, in particular in the area of a magazine compartment 47 located on the underside, which is equipped with a magazine safety element 48.
  • the repeating weapon is viewed from below, the trigger 30 and the repeating lever 09 also being shown.
  • the magazine compartment 47 represents a recess in the forearm 49 of the repeating weapon.
  • a magazine 51 is inserted into the magazine compartment 47, with one or more cartridges (not shown) being able to be arranged in the magazine 51 .
  • the magazine securing element 48 is arranged in an additional depression 52 at the lower end of the magazine compartment 47 , the depression 52 also having a groove 53 .
  • the depression 52 extends perpendicularly to the longitudinal axis 02 of the weapon.
  • the groove 53 extends transversely to the longitudinal axis 02.
  • the magazine securing element 48 is arranged in an initial position in the recess 52 .
  • 10 shows a detailed view of the repeating weapon with the magazine compartment 47 with the magazine safety element 48 in an ejection position.
  • First equals 10 the in 9 shown view, being different to 9 the magazine securing member 48 is in the eject position.
  • the magazine safety element 48 can be brought into the ejection position by a user, with the magazine safety element 48 having been brought from the initial position into an ejection position by being pushed parallel to the longitudinal axis O2 in the direction of the trigger 30 . If the magazine securing element 48 is in the eject position, the magazine 51 can be removed by the user and reinserted into the magazine compartment 47 .
  • the magazine 51 can also be inserted into the magazine compartment 47 when the magazine securing element 48 is in the initial position.
  • FIG. 11 shows a detailed view of the bolt-action weapon with the magazine compartment 47 with the magazine safety element 48 in a safety position.
  • the magazine securing element 48 is brought into the securing position by lateral displacement transversely to the longitudinal axis 02 into the groove 53 of the depression 52 .
  • the magazine securing element 48 can be displaced with one hand.
  • a further advantage is that in the safety position the magazine 51 is secured in the magazine compartment 47 and an unintentional release of the magazine 51 from the magazine compartment 47 by the magazine securing element 48 is also prevented.
