Definitions

• the invention relates to a closure with the features of the preamble of claim 1, according to GB 639 187 A .
• the invention relates to a barrel weapon with such a weapon breech.
• a wedge breech block for a barrel weapon is known.
• the wedge breech block has a locking wedge that can be opened downwards perpendicular to the bore axis of the weapon barrel.
• the DE 198 43 294 C2 discloses a large-caliber barrel weapon with a barrel and a baseplate attached to the barrel on the breech side.
• a longitudinally displaceable catching and ejection device for securing and extracting rimless cartridge cases is formed on the baseplate, which has an ejector pivoting against the pressure of a compression spring.
• the DE 41 33 618 C2 shows an ejector system for barrel weapons, featuring a linearly movable ejector operated by an ejector lever.
• the ejector lever is operated by an actuating cam located on the breech wedge.
• the object of the invention is to create a closure which has an improved ejector system.
• a closure in particular a wedge closure, is provided with a base piece and a closure wedge, comprising an opener shaft with a rotationally fixedly connected opener lever and an ejector system for extracting cartridge cases or cartridge bases from the closure, comprising at least one ejector and at least one ejector lever which actuates the ejector, wherein the ejector lever is rotatably mounted on the opener shaft and the ejector system has at least one transmission element which transmits a rotational movement of the opener lever to the ejector lever.
• a barrel weapon comprising at least one such breechblock or one further developed as described below is provided.
• a barrel weapon is a barrel weapon with a recoiling mass that has at least a barrel and the breech.
• the wedge breech block is in particular a vertical wedge breech block with a breech block that can be moved transversely to the bore axis of the weapon barrel between a closed and open position.
• the closure has a locking mechanism through which the closure can be opened and closed.
• the opening shaft and the opening lever which is connected to the opening shaft for rotation, serve to move the locking wedge between an open and closed position.
• the opening shaft is driven by the locking mechanism.
• At least one ejector lever is mounted on the opening shaft for rotation.
• a rotational movement of the opening shaft is not transmitted directly to the ejector lever, but rather the rotational movement of the opening shaft is transmitted to the ejector lever via the transmission element.
• the ejector lever actuates the ejector, which in turn ejects the cartridge case or the cartridge base.
• a closure with a compact ejector system is created that avoids direct contact between the opening lever and the ejector lever.
• the rotational movement of the opening lever is first transmitted to the transmission element, which in turn transmits the rotational movement to the ejector lever. This prevents a direct impact or shock-like actuation of the ejector lever by the opening lever. This ensures less wear on the opening lever and the ejector lever, thus achieving an improved service life.
• the transmission element is mounted on a first axis which is spaced from the opening shaft.
• the transmission element is arranged as an intermediate element between the ejector lever and the opening lever and can transfer or reduce the rotary movement of the opening lever to the ejector lever.
• a further advantage is that the transmission element can be changed independently of the opener shaft and the ejector lever due to the bearing on the first axis, ensuring easy assembly and disassembly of the transmission element.
• the ejector system has at least one first contact roller arranged at one end of the transmission element for contact with the opening lever and at least one second contact roller arranged at the first end of the transmission element for contact with the at least one ejector lever.
• a first contact roller is formed for each opening lever and a second contact roller is formed for each ejector lever.
• the at least one first contact roller and the at least one second contact roller are arranged on a common second axis.
• the ejector system has at least one pretensioning element that pretensions the transmission element relative to the at least one ejector lever.
• the preload element can be designed, for example, as a spring or as a spring-damper system.
• the at least one ejector lever has a lever arm with an arcuate contact surface which is permanently in contact with the at least one second contact roller.
• the ejector describes a corresponding degressive or progressive characteristic curve in relation to the forward movement.
• the shape of the arcuate contact surface can predetermine the movement characteristics of the ejector.
• the movement characteristics of the ejector can be adjusted by changing the ejector lever.
• the contact surface is designed to be substantially concave, so that the angle of rotation of the rotary movement of the ejector lever describes a progressive characteristic curve compared to the angle of rotation of the rotary movement of the opening lever when opening the closure.
• the progressive characteristic curve ensures that a cartridge base or cartridge to be ejected is continuously accelerated throughout the ejection process, thus ensuring safe ejection of the cartridge or cartridge base.
• the opening lever is designed in such a way that it is not in contact with the first contact roller in the open position of the closure and the first contact roller can be brought into contact with the opening lever during the opening process.
• Fig. 1 shows a schematic perspective view of the breechblock 10 according to the invention with an ejector system 30.

• the first axis 43 is attached to the underside of the base piece 12 with corresponding bearings, which support the axis 43.
• At one end 41a of the transmission element 40 at least one first contact roller 42 is arranged for contact with the opening lever 22. Furthermore, at least one second contact roller 44 is arranged for contact with the at least one ejector lever 34 at the first end 41a of the transmission element 40.
• the ejector system 30 has at least one biasing element 50 that biases the transmission element 40 relative to the at least one ejector lever 34.
• the biasing element 50 is a spring arranged at a second end 41b of the transmission element 40.
• the transmission element 40 is designed in the form of a lever. As shown in Fig. 3a As can be seen, the first end 41a has two fork-like projections on which the axis 46 is arranged. The second end 41b is arranged on the opposite side of the transmission element 40 and is angled relative to the first end 41a.
