Description

[0001] The invention relates to a closure system having the features of the preamble of patent claim 1, according to RU 2 678 934 C1.

[0002] A wedge breech block for a barrel weapon is known from DE 10 2004 052 550 A1. The wedge breech block features a locking wedge that can be opened downwards perpendicular to the bore axis of the weapon barrel.

[0003] From DE 198 04 653 A1, a weapon barrel breech of a large-calibre barrel weapon with a wedge breech is known, which opens and closes the breech exclusively by an external drive, so that no shock loads occur.

[0004] From DE 198 23 785 A1 a vertical wedge bolt for a large-calibre gun is known, which can be opened and closed by means of a cradle-mounted external drive and a cradle-mounted opening lever.

[0005] DE 10 2009 037 899 A1 discloses a wedge breechblock for a barrel weapon with a base plate connected to the rear of the weapon barrel. The wedge breechblock has several locking devices that hold the breechblock wedge in an open position when loading the weapon. The breechblock wedge remains in its open position as long as a rammer holds the locking devices in a position that locks the wedge breechblock when loading a cartridge.

[0006] DE 10 2010 015 570 A1 and DE 101 46 423 A1 each disclose a barrel weapon with a barrel breechblock featuring a wedge breechblock. The wedge breechblock has a base piece and a breech block, which can be opened and closed via a breechblock mechanism. A spring-loaded control unit with movable elements is arranged on the cradle. These actuate the breechblock mechanism on the base piece when the base piece has advanced sufficiently after firing to allow these elements to come into contact.

[0007] DE 10 2010 015 569 A1 concerns a barrel weapon with a wedge breech. A locking mechanism is located on the base of the wedge breech, which can be used to open and close the wedge breech. A guide device is fixed to the cradle of the barrel weapon, which can be used to actuate a lever of the locking mechanism to open and close the breech. If the wedge breech is to remain closed after firing, the guide device must be manually pivoted away.

[0008] The already known gun barrel bolts have an opening lever and a closing lever for manual opening and closing apart from firing a shot, which are operated separately.

[0009] In addition, existing rifle barrel bolts do not allow for intermediate positions of the bolt wedge between the fully open and closed positions. This means that externally driven bolts can only be opened when fully advanced, preventing smoke extractors from achieving optimal effectiveness.

[0010] Based on this, the object of the invention is to create a locking system that automatically locks in the open position.

[0011] This object is achieved by the locking system of claim 1. Advantageous embodiments and further developments are the subject of the respective subclaims.

[0012] According to the invention, a locking system is provided for a weapon barrel, in particular one mounted in a cradle, displaceable from a rest position to a return position, comprising a locking system for a barrel weapon, in particular with a weapon barrel displaceable in a cradle from a rest position to a return position, comprising a base piece with a locking wedge displaceable, in particular transversely to the bore axis of the weapon barrel, between a closed and an open position, a locking mechanism attached to the base piece and a cradle-fixed guide piece with a guide element, wherein the guide element has an actuating element for actuating the locking mechanism, wherein the locking mechanism has a lever mechanism actuable by the actuating element.

[0013] The locking mechanism has a locking lever coupled to the lever mechanism, whereby the locking wedge can be locked in its open position by the locking lever.

[0014] Furthermore, according to the invention, a tube weapon is provided with a cradle and a weapon barrel displaceably mounted in the cradle from a rest position to a return position, comprising at least one such locking system or one further developed as follows.

[0015] The bolt wedge is thus held in place by the bolt mechanism. Loading the weapon and closing the bolt can thus be decoupled. The bolt wedge can thus be kept open independently of loading and unloading.

[0016] By locking the locking wedge in its open position, the closing of the locking wedge is decoupled from the forward travel of the base and the locking mechanism mounted thereon. This ensures that the locking wedge is locked in the open position after opening by the locking mechanism with the locking lever.

[0017] The actuation of the bolt, in particular the opening of the bolt, is carried out by the actuating element attached to the cradle. During continuous firing, the bolt is opened by the actuating element and simultaneously actuated by the lever mechanism in such a way that the bolt can be locked in its open position by the locking lever.

[0018] By using the advance movement, an early and rapid opening of the locking wedge is possible.

[0019] Preferably, the locking system is a gun barrel lock.

[0020] In a further development of the locking system, it can be provided that the locking mechanism has a locking support which interacts with the locking lever and which can be unlocked by the locking lever via an unlocking mechanism which is coupled to the locking support.

[0021] This makes it possible to unlock the wedge regardless of the forward travel position of the base. Unlocking can be achieved regardless of the position of the weapon's recoiling mass—that is, the base and barrel. This ensures that the bolt remains open during the actual loading process until the cartridge is completely loaded. The bolt wedge is only closed again once the unlocking mechanism has been activated.

[0022] This has a particularly positive effect on barrel weapons with an automatic loader, as part of the automatic loader can now unlock and thus close the bolt wedge.

[0023] In addition, a smoke extractor mounted on the weapon barrel achieves an improved effect.

[0024] In a further embodiment of the locking system, it can be provided that the unlocking mechanism is connected to an unlocking cam which is arranged in the base piece opening.

[0025] Preferably, the release cam is actuatable by a part of the automatic loader, such as a cartridge loading head, a loading tray or a loading head.

[0026] This ensures that the unlocking mechanism can be actuated independently of the loading process by a part of the automatic loader, such as a cartridge loading head, a loading tray, or a loading head. The unlocking mechanism is not unlocked immediately after the cartridge is loaded, but only after a part of the automatic loader has been removed from the bolt. The bolt wedge is only closed again when the part of the automatic loader retracts after the actual loading process and the unlocking cam is actuated, thereby actuating the unlocking mechanism and releasing the locking lever from the locking support. Preferably, the locking lever is rotated for this purpose so that it is decoupled from the locking lever by the locking support.

[0027] Alternatively, unlocking can also be done during the loading process in the forward / loading movement of the cartridge loading head.

[0028] Furthermore, unlocking can alternatively also be carried out using the ejector levers if their forward movement during the loading process actuates the locking lever or the locking support by means of a lever, so that the locking lever is decoupled from the locking support and closes the locking wedge.

[0029] The locking wedge is preferably caught in the open position, for which purpose the locking lever is rotated over the locking support by a return spring and is thus blocked.

[0030] In an advantageous development of the locking system, it can further be provided that the lever mechanism comprises a folding lever which interacts with the actuating element in such a way that the lever mechanism can be actuated in one actuating direction by the actuating element and the folding lever can be folded away in a direction opposite to the actuating direction.

[0031] For this purpose, the folding lever works together with the actuating element.

[0032] This ensures that the actuating cam activates the lever mechanism when the weapon advances, allowing the bolt wedge to slide into its open position and lock in this open position. However, when the weapon recoils, the hinged bolt folds away, preventing the lever mechanism from being activated.

[0033] Furthermore, in the design of the locking system, it can be provided that the base piece comprises a bearing in which the cradle-fixed guide piece is mounted in an axially movable manner.

[0034] This allows the base piece to be mounted axially movable relative to the cradle. The cradle-mounted guide piece acts as an anti-twist device between the base piece and the cradle, preventing the base piece from twisting relative to the cradle while still allowing axial movement.

[0035] According to the invention, it is provided that the locking mechanism has a rack and the lever mechanism comprises a toggle lever, wherein the toggle lever comprises a coupling, a toggle joint and a lever, wherein one end of the lever is coupled to the rack and one end of the lever is coupled to the locking lever via the toggle joint of the toggle lever.

[0036] Furthermore, the locking mechanism can be provided with an opening shaft with a gear, wherein the gear engages with the rack. The gear is arranged on the opening shaft in a rotationally fixed manner.

[0037] In a design of the locking system, it can be provided that the opening shaft has an opening lever which interacts with the locking wedge in such a way that the locking wedge can be moved between a closed and an open position by the opening lever.

[0038] The opening lever is firmly connected to the opening shaft so that the locking wedge can be moved in its position by turning the opening shaft.

[0039] In a further development of the locking system, it can be provided that the actuating element is designed in such a way that, when the barrel weapon is advanced, it interacts with the lever mechanism in such a way that the locking wedge can be displaced between the closed and the open position by means of the lever mechanism, in particular in interaction with at least the rack, the gear wheel, the opening shaft and the opening lever.

[0040] Furthermore, it can be provided that the rack is connected to a wedge closing spring, in particular arranged in the rack, by means of which the locking wedge can be pretensioned in the open position towards its closed position.

[0041] The wedge closing spring slows down the locking wedge when it is moved from the closed to the open position and stores energy in the open position. When the wedge is unlocked, the wedge closing spring provides the energy to move the wedge from the open to the closed position.

[0042] In addition, it can be provided that the locking system has a drive, in particular a linear drive, which is designed to realize an axial displacement between the drive and the guide element, so that the actuating element can be displaced in its position relative to the lever mechanism by the drive.

[0043] This makes it possible to operate the locking mechanism in such a way that the locking wedge can be moved between the closed and open positions independently of the weapon's forward or reverse travel.

[0044] The drive allows the locking wedge of the locking system to be opened and closed in its rest position. Furthermore, the drive allows the locking wedge to be positioned in intermediate positions between the closed and open positions. These intermediate positions can be reached without causing any safety issues.

[0045] This can ensure improved smoke extraction by the smoke extractor.

[0046] Preferably, the drive and actuating element are designed such that they decouple automatically as soon as the bolt wedge is opened due to a shot being fired. The bolt actuation by the drive is thus decoupled from the forward movement of the recoiling mass.

[0047] This means that unwanted intermediate positions of the drive and the actuating element do not lead to dangerous operating conditions or damage to the locking mechanism.

[0048] Another advantage is that only one drive is used for the opening and closing functions. Furthermore, the function of keeping the bolt closed after the shot can be implemented. All essential functions for operating the bolt wedge can be implemented by one drive, such as opening in advance, closing and opening on demand, and / or keeping the bolt closed after the shot.

[0049] Furthermore, the drive can be designed in such a way that the locking wedge can be opened by the actuating cam and can also be opened and / or closed by the drive.

[0050] Preferably, the actuating cam can be spring-loaded and / or damped relative to the drive. A spring and / or damper can be provided at the appropriate location. Furthermore, a preloaded spring is preferably provided.

[0051] This allows maximum forces to be reduced and correspondingly weaker commercially available drives to be used.

[0052] In an embodiment, it can also be provided that the guide element is designed as a guide carriage which is mounted axially displaceably on the guide element, wherein the guide carriage is mounted axially displaceably along the guide rail.

[0053] In this case, the actuation is achieved by means of the guide carriage, which is mounted on the guide profile for linear movement. The position of the guide carriage is determined by the drive. The transmittable force is limited by a spring-loaded mechanism. The actuating cam, which activates the lifting mechanism, is located on the guide carriage.

[0054] Furthermore, it can be provided that the guide element is designed as a guide profile with the actuating element, wherein the guide profile is displaceably mounted directly on the base piece.

[0058] The barrel weapon 1 comprises, in addition to the locking system 10, a cradle 40 and a weapon barrel 20, which is slidably mounted in the cradle 40. The weapon barrel 20 is slidably mounted in the cradle 40 between a rest position and a return position. The locking system 10, which has a base piece 12, is arranged at the end of the weapon barrel 20. Barrel brakes 30 and barrel pre-hollowers are formed between the base piece 12 and the cradle 40.

[0059] The locking system 10 is thus provided for the weapon barrel 20 which is mounted in the cradle 40 so that it can be moved from a rest position to a return position.

[0060] The closure system 10 comprises the base piece 12, comprising a closure wedge 14 displaceable between a closed and an open position, a closure mechanism 100 attached to the base piece 12 and a cradle-mounted guide piece 105 with a guide element 110.

[0061] As in the Fig. 8 As can be clearly seen and described in detail below, the guide element 110 has an actuating element 114 for actuating the locking mechanism 100. The locking mechanism 100 further comprises a lever mechanism 150 actuated by the actuating element 114. Furthermore, the locking mechanism 100 comprises a locking lever 161 coupled to the lever mechanism 150, wherein the locking wedge 14 can be locked in the open position by the locking lever 161.

[0063] The closure system 10 has a drive 130, which is particularly designed as a linear drive. The drive 130 is configured to realize an axial displacement of the actuating element 114 in its position relative to the lever mechanism 150.

[0064] According to the first embodiment, the guide element 110 is designed as a guide carriage 110 mounted axially displaceably on the guide element 110. The guide carriage 110 is mounted axially displaceably along the guide piece 105.

[0065] Fig. 3 shows a further schematic perspective view of the closure mechanism 100 of the closure system 10 according to the invention according to the first embodiment, wherein Fig. 3 the underside of the locking system10.

[0066] The locking mechanism 100 has an opening shaft 120 with a gear 122, wherein the gear 122 engages with a rack 140 of the locking mechanism 100. The opening shaft 120 is attached to the underside of the base piece 12 via bearings 124 and has an opening lever 126. The opening shaft 120 is driven by the gear.

[0067] The opening shaft 120 has an opening lever 126 that interacts with the locking wedge 14 such that the locking wedge 14 can be moved between a closed and an open position by the opening lever 126. For this purpose, the opening lever 126 is connected to the opening shaft 120 in a rotationally fixed manner. Fig. 3 shows the locking wedge 14 in the closed position. To open, the locking wedge 14 is moved downwards from this closed position into its open position.

[0068] The rack 140 is connected to a wedge closing spring 142 arranged in the rack 140. The wedge closing spring 142 allows the locking wedge 14 to be preloaded from the open position toward its closed position by the wedge closing spring 142.

[0069] The locking system 10 further includes an ejector system 200 for extracting cartridge cases or cartridge heads from the locking system 10. The ejector system 200 includes at least one ejector 232 and at least one ejector lever 234 that actuates the ejector 232.

[0070] The ejector lever 234 is rotatably mounted on the opener shaft 120 and the ejector system 200 has at least one transmission element 240 which transmits a rotational movement of the opener lever 120 to the ejector lever 234.

[0071] The transmission element 240 is mounted on a first axle 243, which is spaced apart from the opening shaft 120. The first axle 243 is attached to the underside of the base piece 12 with corresponding bearings, which support the axle 243.

[0072] At one end 241a of the transmission element 240, at least one first contact roller is arranged for contact with the opening lever 126. Furthermore, at least one second contact roller 244 is arranged for contact with the at least one ejector lever 234 at the first end 241a of the transmission element 240. The at least one first contact roller and the at least one second contact roller 244 are arranged on a common second axis 246.

[0073] The ejector system 230 has at least one biasing element 250 that biases the transmission element 240 relative to the at least one ejector lever 234. According to the embodiment, the biasing element 250 is a spring arranged at a second end 241b of the transmission element 240.

[0074] The transmission element 240 is designed in the shape of a lever. The first end 241a has two fork-like projections on which the axle 246 is arranged. The second end 241b is arranged on the opposite side of the transmission element 240 and is angled relative to the first end 241a.

[0075] In Fig.1 It can be seen that two ejector levers 234 are formed, for each of which a second contact roller 244 is formed.

[0077] The toggle lever 151 has a coupling 152 and a lever 154. One end of the lever 154 is coupled to the rack 140 and one end of the lever 154 is coupled to the locking lever 161 via a toggle joint 153 of the toggle lever 151, as shown, for example, in Fig. 4 bis 6 can be seen.

[0078] Fig. 5 shows a further schematic sectional view of the closure mechanism 100 of the closure system 10 according to the invention according to the first embodiment.

[0079] The locking mechanism 100 has a locking support 160 that interacts with the locking lever 161. The locking support 160 can be unlocked by the locking lever 161 via an unlocking mechanism 162 coupled to the locking support 160.

[0080] Fig. 6 shows a further schematic perspective view of the closure mechanism 100 of the closure system 10 according to the invention according to the first embodiment. Fig. 6 It can be seen that the lever mechanism 150 comprises a folding lever 156. The lever mechanism 150 can be actuated via the folding lever 156 in one actuation direction by the actuation element 114. In a direction opposite to the actuation direction, the folding lever 156 can be folded away.

[0081] In the Fig.4 bis 6 It is shown that the actuating element 114 is designed such that, when the barrel weapon 1 advances, it interacts with the lever mechanism 150 such that the locking wedge 14 can be displaced between the closed and the open position by means of the latter, in particular in operative connection with at least the toothed rack 140, the gear wheel 122, the opening shaft 122 and the opening lever 126.

[0082] Fig. 7 shows a further schematic sectional view of the closure mechanism 100 of the closure system 10 according to the invention according to the first embodiment.

[0088] Furthermore, the ejector lever 137 has a second lever arm. The second lever arm serves to actuate the ejector 137.

[0089] The contact surface 238 of the first lever arm 236 is substantially concave, so that the angle of rotation of the rotary movement of the ejector lever 127 relative to the angle of rotation of the rotary movement of the opener lever 126 describes a progressive characteristic curve when opening the closure system 10.

[0090] The opening lever 126 is designed such that it is not in contact with the first contact roller in the open position of the closure system 10 and the first contact roller can be brought into contact with the opening lever 126 during the opening process.

[0091] As in Fig. 11a und Fig. 11b As can be seen, the opening lever 126 has a projection with a contact surface 223, which can be brought into contact with the first contact roller. The contact surface 223 of the opening lever 126 is essentially flat.

[0092] Fig. 12 shows a schematic diagram of the angle of rotation of the opening lever 126 and the angle of rotation of the ejector lever 127 with respect to the forward movement. The diagram shows that, with respect to the forward movement, the angle of rotation of the opening shaft 20 changes linearly, and the angle of rotation of the ejector 232 describes a progressive characteristic curve.

[0093] Fig. 13 shows a schematic perspective view of the closure mechanism 100 of the closure system 10 according to the invention according to a second embodiment. According to the second embodiment of the invention, the guide element is designed as a guide profile 110'. The guide profile 110' directly encompasses the actuating element 114. The guide profile 110' is displaceably mounted directly on the base piece 12 and displaceably on the cradle tube.

[0094] Fig. 14 shows a further schematic perspective view of the closure mechanism 100 of the closure system 10 according to the invention according to a second embodiment. As in Fig. 14 As shown, the actuating element 114 is part of the guide profile 110'. The actuating element is designed as a projection extending downward from the guide profile.

[0095] The actuation can be carried out by the cradle-mounted linear drive on the downwardly extending projection.

[0096] Furthermore, a force-limiting spring element is disclosed. BEZUGSZEICHENLISTE
