Description

[0001] Device for catching and ejecting a bullet casing

[0002] The invention relates to a device for catching and ejecting a projectile casing, in particular a casing base, having a catching device which is movable between a catching position and an ejection position, wherein the projectile casing can be caught in the catching device in the catching position and ejected from the latter via an ejector in the ejection position.

[0003] Such devices are used particularly in military vehicles capable of firing large-caliber ammunition. Depending on the projectile, an unfired projectile casing, such as the base of the projectile, may remain in the weapon barrel and must first be ejected before the next projectile can be fired.

[0004] For example, it is known to collect or temporarily store the bullet casings in the vehicle and then remove them all from the vehicle at the next opportunity. It is also known to eject the bullet casings directly from the vehicle. EP 0 149 014 A2 discloses a device with which the corresponding casings can be caught after the bullet has been fired and then ejected directly from the vehicle. The device has a collecting device that can be moved into a collecting position behind the weapon barrel so that the bullet casing of a bullet can be caught in the collecting device after it has been fired. In order to then eject the bullet casing, the collecting device can be moved into an ejection position and in this position the collected casing can then be ejected from the collecting device and thus also from the vehicle via an ejector.

[0005] However, the design described in EP 0 149 014 A2 has the disadvantage that the catching device must first be moved from the catching position to the ejection position via a drive, before the ejector must then be actuated in the ejection position via another drive to finally eject the bullet casing. Due to the various drives for moving the catching device and the ejector, this device is comparatively complex in terms of controlling the drives.

[0006] Based on this, the invention sets itself the task of providing a device for catching and ejecting a bullet casing, which is characterized by a simplified structure. This task is achieved in a device of the type described above in that the ejector can be automatically moved into a cocking position by a movement of the catching device and can be automatically triggered upon reaching the ejection position.

[0007] This design only requires the active movement of the catching device via a single drive, eliminating the need for a separate drive for both movement and triggering of the ejector. Rather, the movement and triggering of the ejector can be initiated via the catching device's drive, allowing the movement and triggering of the ejector to be purely passive. Overall, the catching device and the ejector can thus be moved via a shared drive.

[0008] Furthermore, no additional control is required to trigger or accelerate the ejector and thus to eject the bullet casing. This is because the coupling allows the ejector to be cocked by moving the catching device, and when the ejection position is reached, this pre-tension can then be automatically released, so that the bullet casing is automatically ejected via the ejector. The ejector can therefore advantageously be coupled to the catching device in such a way that it is moved into a cocked position when the catching device is moved and is automatically triggered when the ejection position is reached. Once the ejector has been moved into the cocked position, it can be accelerated together with the bullet casing by a trigger. The bullet casing can then be ejected from the vehicle as a result of this acceleration.

[0009] According to an advantageous development of the invention, it is proposed that the ejector is coupled to the collecting device in such a way that it is automatically moved into the cocking position when the collecting device moves, in particular from the ejection position to the collecting position. In the collecting position, the collecting device can be arranged behind the weapon barrel so that after a projectile has been fired, the remaining bullet casing can be collected in the collecting device. In the ejection position, the collecting device can be pivoted upwards so that the received bullet casing can then also be ejected upwards. Due to this design, the ejector can therefore already be cocked when the collecting device is pivoted down into the collecting position. The ejector is therefore advantageously pre-tensioned when it is not in contact with a bullet casing to be ejected.when there is no bullet casing in the catching device. This ensures particularly reliable movement of the ejector into the cocking position. The ejector can therefore already be pre-cocked in the catching position. Due to the automatic movement of the ejector, no additional drive is required. Rather, the ejector is moved automatically due to a mechanical coupling with the catching device or with the movement of the catching device.

[0010] In a further development of the invention, it is proposed that the bullet casing can be ejected from the collecting device against the force of gravity via the ejector. The bullet casing can therefore not only be pushed out of the collecting device, but can also be accelerated to such an extent that it can be accelerated against the force of gravity, e.g. diagonally upwards, and ejected or shot out of the vehicle. In this respect, it can also be ensured that the bullet casing only hits the ground at a sufficient distance from the vehicle. The bullet casing can be accelerated together with the ejector in an ejection direction, whereby the ejection direction can be inclined upwards relative to the horizontal. From a design point of view, it has proven advantageous if the ejector is arranged within the collecting device.The ejector can be located behind a captured bullet casing, allowing the bullet casing to be accelerated via the ejector. Furthermore, the ejector can be guided within the catching device, particularly linearly guided. This ensures reliable movement and acceleration of the ejector in the ejection direction. Jamming or tilting of the ejector can thus be prevented.

[0011] Furthermore, it has proven advantageous if the ejector is mechanically coupled to the catching device. This design allows the ejector to be mechanically initiated by a movement of the catching device. The ejector can be positively coupled to the catching device so that it is automatically retracted and thus pre-tensioned when the catching device moves into the catching position. No additional intervention is required.

[0012] According to a further advantageous development of the invention, it is proposed that the collecting device is movable both translationally and rotationally during a movement between the collecting position and the ejection position. The collecting device can be pivoted upwards during a corresponding movement and simultaneously tilted upwards so that the ejection direction is inclined upwards relative to the horizontal. In this respect, a movement superimposed from a translational and a rotational movement can take place. In the collecting position, the collecting device can be arranged in line with the weapon barrel so that reliable reception of the bullet casing is ensured. By pivoting upwards and simultaneously tilting upwards, the bullet casing can then be ejected diagonally upwards out of the vehicle when the ejector is triggered.Furthermore, it has proven advantageous if the collecting device can be moved between the collecting position and the ejection position using a single drive. The collecting device can be moved or pivoted both upwards into the ejection position and downwards again into the collecting position using this single drive. The single drive therefore results in a very simple structure and very simple control. Alternatively, however, several drives can of course be provided for moving the collecting device so that it can still be moved, for example, even if one drive fails. However, due to the coupling, no additional drive is required for moving the ejector or the components described in more detail below.

[0013] With regard to the drive, it has proven advantageous if it is designed as a lifting cylinder. The lifting cylinder can, for example, be extended and retracted hydraulically or pneumatically and connected to the vehicle's corresponding hydraulic or pneumatic network. When the lifting cylinder is extended, the collecting device can be moved or pivoted from the collecting position to the ejection position, essentially upwards. When the lifting cylinder is retracted, the collecting device can be moved or pivoted from the ejection position back to the collecting position, essentially downwards.

[0014] To implement the movement of the catching device, a trapezoidal rod assembly can be provided, which is connected to the catching device on one side and to a mounting element on the other. The trapezoidal rod assembly allows for a combined translational and rotational movement of the catching device between the catching position and the ejection position. The trapezoidal rod assembly can guide the catching device purely mechanically in this manner, and no further control of this movement of the catching device is required. The trapezoidal rod assembly can thus be positively guided.

[0015] From a structural perspective, the trapezoidal rod assembly can comprise two rods of different lengths and a lever that pivots between the two rods at their ends. The fall arrester can be rigidly connected to the lever and thus move with it. The rotational movement or tilting of the fall arrester can depend on the length of the two rods and their endpoints. To achieve a corresponding rotational movement during a translational movement, the rods advantageously have different lengths, and they can also have different distances from each other at their ends. The endpoints of the rods can thus form a trapezoid.

[0016] At the opposite end regions of the two rods connecting the levers, these can be pivotably mounted on a mounting element. The mounting element can be designed as a mounting plate and arranged on the weapon side. When moving between the catch position and the ejection position, the two rods can be pivoted relative to the mounting element. The respective pivot axes can extend horizontally parallel to each other and be offset from each other in two directions. This offset in two directions, in conjunction with the different rod lengths, allows the lever or catch device to be automatically rotated or tilted during a movement.

[0017] Furthermore, it has proven advantageous if the mounting element can be connected to the recoiling part of a weapon. In this respect, the mounting element and thus also the trapezoidal rods and the collecting device can recoil together with the weapon when a projectile is fired due to the recoil. Two mounting elements are advantageously arranged to the left and right of the weapon so that the collecting device can be held centrally behind the weapon and thus in line with the weapon barrel. By arranging it on the recoiling part of the weapon, reliable collection of the bullet casing can be ensured after the shot has been fired. In particular, collection occurs when the weapon barrel is still moving due to the recoil. The collecting device can therefore be arranged fixed to the weapon.

[0018] To move the collection device, it has proven advantageous if the drive is coupled to a rod of the trapezoidal rod system. The drive allows the corresponding rod to be pivoted up or down. The rod is moved about its pivot point connected to the mounting element. By connecting the two rods via the lever, the drive can only actively drive one rod, but the other rod can be moved accordingly. In the collection position, the two rods can be arranged essentially parallel to one another, and at an angle in the ejection position. The upper of the two rods is advantageously longer than the lower rod. This initiates the tilting movement of the collection device described above.

[0019] Furthermore, it has proven advantageous to provide a locking device for locking the trapeze rod in the ejection position. This locking device prevents the trapeze rod, and thus the catching device, from moving when the weapon recoils. Even the high forces that sometimes occur when the weapon recoils cannot lead to unintentional movement of the trapeze rod or the catching device. The locking device can secure or fix at least one of the rods to the mounting element. By positively coupling the two rods and the lever, by fixing one rod, the other rod, the lever, and thus also the catching device can be prevented from moving.

[0020] According to an advantageous development of the invention, it is proposed that the drive can be automatically decoupled from the catching device. If the drive is decoupled, no power can be transmitted between the drive and the trapeze rods or the catching device. The drive can be stationary and thus decoupled from the recoiling part of the weapon. For example, the drive can be arranged on the cradle of the weapon. When the weapon recoils, a relative movement can therefore occur between the drive and the trapeze rods or the catching device. This relative movement can achieve automatic decoupling. The forces and accelerations acting on the drive can be kept within manageable limits by the decoupling, which ensures long-term functionality of the drive. The trapeze rods orThe catching device is thus arranged in the catching position and can move linearly relative to the drive. The trapeze rod and the catching device can retract together with the weapon without negatively affecting the drive.

[0021] From a design point of view, it has proven advantageous if the drive is coupled to the trapezoidal rod system, in particular to a rod of the trapezoidal rod system, via a jaw connection. The rod of the trapezoidal rod system can be pivoted up and down in the effective direction of the drive via the jaw connection, and at the same time, automatic decoupling can take place when the weapon recoils. The drive-side jaw can be open in the direction of the weapon's recoil for this purpose. The drive is preferably arranged such that its effective direction is angular and thus not parallel to the weapon's recoil direction. For connection to the drive, the trapezoidal rod system can have a coupling bolt which is coupled to the drive for moving the collecting device between the collecting position and the ejection position.The coupling pin can be located on one of the rods, particularly the lower rod, and protrude sideways. To couple it to the drive, the coupling pin can be located in the drive's mouth. When the weapon recoils, the coupling pin can then move out through the opening in the mouth, allowing automatic decoupling. When the weapon returns to its original position after recoiling, the coupling pin can also move back into the mouth automatically. In the next step, the rod can then be moved upwards via the coupling pin by extending the drive, thus moving the catcher device into the ejection position.

[0022] Furthermore, it has proven advantageous if the collecting device is adapted to the geometry of the bullet casing to be collected. This design ensures that the bullet casing is reliably held in the collecting device when it moves and can only move to a small extent within the collecting device. Since the bullet casing to be collected usually has a round cross-section, the collecting device can also have a receiving area with a substantially round cross-section. The diameter of the collecting device or of the receiving area can essentially correspond to the caliber of the bullet and therefore also to the diameter of the bullet casing. The ejector can be arranged so that it can move in the receiving area, in particular in a linear direction or in the ejection direction. The receiving area can serve as a guide for the ejector. Overall, the collecting device orThe receiving area should be cup-shaped. The ejector can be designed as an ejection plate. This allows the projectile casing to be ejected to rest as flatly as possible against the ejector and be accelerated evenly in the ejection direction.

[0023] Furthermore, the catching device can have a catching area in which the bullet casing can be caught in the catching position. The catching area can be funnel-shaped and thus guide the caught bullet casing toward the receiving area. The catching area can be arranged in front of the receiving area and, in the catching position, directly behind the weapon barrel. From a structural perspective, the catching area can be designed in the shape of a cylinder. Furthermore, the catching area can have two openings opposite each other with respect to the central axis, which prevent the bullet casing from tilting during catching.

[0024] According to an advantageous development, it is proposed that the collecting device be closed at one end by a base. The base can limit the receiving area downwards, thus also limiting the movement of the ejector. The ejector can be arranged parallel to the base in the ejection position and can be moved in the normal direction to the base. During clamping, the ejector can be moved toward the base of the collecting device. To prevent air from accumulating between the ejector and the base, the base can have a pressure outlet opening so that the air can escape to the outside.

[0025] From a design perspective, it has also proven advantageous if the collecting device has at least one lateral recess and the ejector has at least one lateral projection area extending through the recess. Two lateral recesses are advantageously arranged on opposite sides, and the ejector can therefore also advantageously have two correspondingly projecting projection areas. The recesses can extend in the ejection direction and thus ensure reliable linear guidance of the ejector in the collecting device.

[0026] Furthermore, it has proven advantageous if the collecting device has a guide rail extending in the ejection direction for guiding the movement of the ejector. The guide rail can be arranged next to the recess and the projection area of ​​the ejector can thus extend through the recess and then be guided on the guide rail. During a movement, i.e. during clamping or ejection, the ejector moves forwards or backwards, guided by the guide rails. The guide rail can be designed as a guide rod and the projection area of ​​the ejector can accordingly have a round recess which is guided on the corresponding guide rail like a sliding guide. Two guide rails are advantageously provided on opposite sides so that the ejector is guided accordingly on both sides and the force is distributed as evenly as possible.

[0027] According to a design development, the guide rail is provided with a damper by means of which movement of the ejector in the ejection direction can be dampened. Since the ejector is greatly accelerated when ejecting a bullet casing in order to ensure that the bullet casing is ejected sufficiently far, the damper can reduce high material stress. The damper is therefore advantageously arranged in the front end region of the guide rail. Furthermore, it has proven advantageous to provide a tensioning device by means of which the ejector can be automatically tensioned when the collecting device is transferred from the ejection position to the collecting position. When tensioning, the ejector can be moved against the ejection direction and thus towards the base of the collecting device.The ejector can thus be coupled to the catching device via the clamping device, in particular by mechanically forcibly coupling it. Automatic tensioning eliminates the need for an additional drive; rather, it can be done automatically by rotating the tensioning shaft relative to the catching device. Thus, a movement of the catching device can actuate the clamping device and move the ejector into the clamped position. The ejector can thus be coupled to the catching device via the clamping device.

[0028] Furthermore, it has proven advantageous if a spring is provided, whereby the ejector can be moved via the tensioning device against the force of the spring. When pretensioned, the ejector can compress the spring and the spring can thus be pretensioned in the ejection direction. The spring can be arranged between the ejector and the base of the collecting device so that it is tensioned when the ejector moves towards the base of the collecting device. In order to achieve uniform movement of the ejector, several springs can be provided. A spring package consisting of several springs is advantageous. In the tensioned position, the spring or springs can go to a block and thus be maximally compressed.

[0029] From a design perspective, it has also proven advantageous if the tensioning device has a tensioning shaft that is rotatable relative to the catching device when the catching device moves between the ejection position and the catching position. Advantageously, the tensioning shaft automatically rotates relative to the catching device due to the movement of the catching device. Due to the relative movement between the tensioning shaft and the drive device, and thus also of the ejector, the ejector coupled to the tensioning shaft can also be moved relative to the catching device when the catching device is transferred from the ejection position to the catching position, preferably backwards against the force of the spring.Furthermore, the relative movement of the tensioning shaft and the catch device, which can be caused by the movement of the catch device, can also actuate the tensioning device and the holding device, described in more detail below. The entire tensioning and release mechanism can thus be initiated via the movement of the catch device.

[0030] It is advantageous if the tensioning shaft is connected in a rotationally fixed manner to a rod of the trapezoidal rod system, so that when the collecting device moves between the collecting position and the ejection position, the tensioning shaft rotates relative to the collecting device. In this respect, when the collecting device moves, the tensioning shaft can be rotated relative to the collecting device automatically and without an additional drive. The tensioning shaft can be mounted at the end in a lever of the trapezoidal rod system and be connected in a rotationally fixed manner to a rod of the trapezoidal rod system, in particular the lower rod. Since the rod can rotate relative to the lever when moving from the ejection position to the collecting position and the collecting device is firmly connected to the lever, the rod and thus also the tensioning shaft also rotate relative to the collecting device when moving accordingly.When the collecting device is transferred from the ejection position to the collecting position, the tensioning shaft advantageously rotates rearward relative to the collecting device, so that the ejector is also pulled rearward against the force of the spring. Two tensioning devices are advantageously provided, one arranged on one side and the other on the other side of the collecting device. The ejector can thus be pulled rearward and pre-tensioned evenly via the two tensioning devices. Accordingly, two tensioning shafts can then also be provided, which has also proven advantageous with regard to triggering the ejector via the triggering device described in more detail below.

[0031] Furthermore, it has proven advantageous if the clamping shaft has a clamping segment that is non-rotatably connected to the clamping shaft. This connection allows the clamping segment to rotate in parallel with the clamping shaft. The clamping segment can be designed as a gear ring with a circumferential extension of 90 degrees. As described in more detail below, a corresponding quarter-gear ring is sufficient to clamp the ejector.

[0032] According to a further advantageous embodiment of the device, it is proposed that the tensioning device has a tensioning chain which engages with the tensioning segment such that the tensioning chain can be moved by rotation of the tensioning shaft. The tensioning chain can be placed over the tensioning segment and connected to it in a form-fitting manner. The tensioning chain and the tensioning segment can thus be connected to one another in the manner of a pinion-chain connection. In this way, a rotational movement of the tensioning shaft relative to the collecting device can be converted into a linear movement of the tensioning chain relative to the collecting device. The tensioning chain can be connected, in particular at one end, to the ejector or to a projection area of ​​the ejector. The ejector can thus be moved into the tensioning shaft via the tensioning chain. The ejector can thus be automatically pulled backwards against the spring when the collecting device moves.The tensioning chain can be connected to a spring at the opposite end, ensuring that the tensioning chain does not slip off the tensioning pinion, but can be reliably moved via the pinion. The length of the tensioning chain can be dimensioned such that it is reliably in contact with the tensioning segment in both the ejection and collection positions.

[0033] An advantageous development of the invention provides that the ejector can be held in the clamped position by means of a holding device. Once the ejector has been clamped by the clamping device and has reached the clamped position, it can be held or fixed in the clamped position by the holding device. It is therefore not necessary for the clamping device to continuously hold the ejector in the clamped position. It is advantageous if the holding device is designed as a locking device which holds the ejector in the clamped position by means of a locking connection. By means of a corresponding locking connection, the holding device can interact with the ejector in a form-fitting manner and thus prevent it from moving. For fixing, the locking device can engage in the ejector and thus prevent it from moving. Alternatively, however, it is also possible for the ejector to engage in the holding device or to lock behind it.

[0034] With regard to the holding device, it has further proven advantageous if it is designed in such a way that it can be moved into the position holding the ejector by a movement of the ejector. This design enables the ejector to be held automatically in the clamped position by its movement, so that no additional control is required for the holding device. Rather, the ejector can be held in the clamped position purely passively in the sense of a self-locking mechanism, and no additional drive is required to move the holding device. According to a structurally advantageous development of the invention, it is proposed that the holding device be designed as a rocker, in particular a self-locking one. When the trigger is pulled into the clamping position, this can actuate the rocker, whereby one end of the rocker is pivoted into the trigger to hold it.This corresponding holding end can have a hook-shaped geometry. The opposite end can be positioned in the travel path of the trigger, so that when the trigger is moved into the clamping position, it strikes this end and pushes it out of the travel path. This allows the rocker to be actuated, and the other end pivots into the trigger and secures it. The rotation axis of the holding device or rocker can be positioned radially outside the travel path of the ejector.

[0035] According to an advantageous development, it is proposed that a catch be provided which prevents movement of the bullet casing in the collecting position. Furthermore, the catch can also prevent unintentional movement of the ejector, for example, if the holding device malfunctions. The catch can extend into the interior of the collecting device and thus prevent movement of the bullet casing or ejector. The catch can be spaced a certain distance from the ejector so that sufficient space remains between the catch and the ejector for the bullet casing. The catch can prevent the bullet casing from moving unintentionally when the collecting device is transferred into the ejection position.

[0036] The gate can be designed in such a way that it allows the bullet casing to pass through in one direction, particularly in the cocking direction, but prevents movement in the opposite direction. This also prevents the ejector from moving over the gate in the ejection direction if the ejector protrudes into the interior of the catching device. The gate can be designed as a spring-loaded bevel which, when contacted in the cocking direction, automatically deflects the force of a spring, for example, whereas contact in the opposite direction does not result in movement of the gate. The gate can be arranged at a distance from the holding device in the axial direction. In particular, the gate can be arranged in front of the holding device in the cocking direction.

[0037] Furthermore, it has proven advantageous to provide a trigger device for automatically triggering the ejector in the ejection position. The ejector can be triggered via the trigger device so that it can spring forward in the ejection direction and accelerate the bullet case accordingly. The ejector can be triggered by releasing the holding device. To do this, the trigger device can release the connection between the holding device and the ejector, e.g. by moving the holding device, in particular pivoting it. When a cocked trigger is triggered, it can be accelerated in the ejection direction together with the case, driven by the spring. Thanks to the automatic trigger, no separate drive or external intervention is required for triggering; instead, triggering can be positively coupled via a rotation of the cocking shaft.In this respect, the triggering device can also be actuated by a movement of the collecting device and the ejector can be triggered by a movement of the collecting device.

[0038] Furthermore, it has proven advantageous if the holding device can be secured in the ejector-holding position via the release mechanism. Once the holding device is appropriately secured, it cannot be moved, thus reliably preventing movement of the ejector and unintentional movement due to the spring's preload. When the release mechanism is triggered, the holding device can be released and moved into the ejector-releasing position by the ejector's preload. The ejector can then spring forward and eject the bullet casing.

[0039] Furthermore, it has proven advantageous if the holding device can be moved into the release position via the ejector. The holding device can therefore be designed not only to be self-locking, but also to be self-unlocking. The ejector can have an engagement contour into which the holding device or one end of the holding device can engage to hold the ejector. The contour can be designed such that, due to the pretension of the ejector in the ejection direction, it tends to transfer or pivot the holding device into the release position. The ejector can therefore be held in the clamped position solely by the release device. When the release device releases the holding device, the holding device can be pivoted into the release position by the ejector itself.Advantageously, the holding device can therefore only hold the ejector in the clamping position in conjunction with the release device. However, the holding device can also be preloaded, for example, via a spring, into the position that releases the ejector.

[0040] From a design perspective, the triggering device can have a retaining pin that is movable in the ejection direction. The retaining pin can engage behind the retaining device when the ejector moves the retaining device, or can engage in the retaining device when the retaining device has reached its position holding the ejector. The retaining pin can be pre-tensioned into the position securing the retaining device. By pulling the retaining pin or by moving the retaining pin in the tensioning direction, the retaining device can be released, thus releasing the ejector. The retaining pin can extend through the base of the collecting device and thus be accessible from outside the collecting device.

[0041] Furthermore, it has proven advantageous if the triggering device has a triggering slide for triggering the ejector. The triggering slide can release the holding device and thus trigger the ejector. The triggering slide can be arranged outside the collecting device so that the space available inside the collecting device is not affected. Advantageously, the triggering slide is guided on the outside of the collecting device and can be moved linearly in the tensioning direction, i.e. pulled backwards, to trigger the ejector. The retaining bolt can be movable over the triggering slide. From a structural point of view, the retaining bolt can be guided through an opening in a section of the triggering slide that extends parallel to the base of the collecting device and can be connected at the end to a projection element that extends in the radial direction.This can prevent the retaining pin from slipping through the opening of the trigger slide in the ejection direction. Instead, the retaining pin can be moved backward by the trigger slide when the trigger slide and the projection element make contact. The projection element can then rest flat against the retaining pin in the area around the opening.

[0042] With regard to the triggering mechanism, it has proven advantageous if it can be triggered automatically by a movement of the catching device. This eliminates the need for a separate drive for triggering; instead, once the catching device has reached the ejection position, the bullet casing can be ejected automatically. For this purpose, the triggering slide can be automatically moved rearward upon reaching the ejection position, triggering the ejector. The triggering mechanism or the triggering slide can be positively coupled to the catching device for this purpose.

[0043] With regard to automatic release, it has proven advantageous if the release device, in particular the release carriage, is coupled to the tensioning shaft. When the collecting device is pivoted up or moved from the collecting position to the ejection position, the tensioning shaft can rotate relative to the collecting device and thus also relative to the release device. This relative movement can move the release carriage backwards in or shortly before reaching the ejection position, so that when the ejection position is reached, it has been moved far enough back that the holding device is released and the ejector can be moved in the ejection direction. From a design point of view, a cam can be arranged on the tensioning shaft, which can move the release carriage backwards when the tensioning shaft rotates.Thus, the tensioning shaft can be coupled to the release slide via the cam in such a way that the release slide releases the holding device when the ejection position is reached, so that the ejector is automatically triggered.

[0044] Unlike when the catching device is pivoted downwards, i.e., when moving from the catching position to the ejection position, in which the ejector is moved in the clamping direction against the force of the spring, a positive coupling with the ejector or clamping device cannot be provided when moving from the catching position to the ejection position. Rather, the clamping segment can have a recess, e.g., of 90 degrees, that decouples the clamping device when the catching device moves from the catching position to the ejection position. Therefore, when moving to the ejection position, only a coupling between the clamping shaft and the release device or the release slide can exist.

[0045] According to an advantageous development of the invention, the trigger slide is movable against the force of a spring, particularly in the tensioning direction. A corresponding pulling movement can thus tension the spring, so that the trigger slide is pretensioned in the opposite direction. From a structural point of view, the spring can be designed as a tension band, particularly an elastically deformable one, which is tensioned when the trigger slide is pulled backward for triggering. It can be provided that two tension bands are provided per trigger slide, which are advantageously arranged in the front part of the respective trigger slide.

[0046] Furthermore, it has proven advantageous if the catch can be moved via the trigger mechanism. The catch can be coupled to the trigger slide so that when the trigger slide is retracted, it can be pivoted out of the interior of the catching device, thus clearing the path for the ejector and the bullet casing.

[0047] Furthermore, it has proven advantageous to provide several holding devices so that the ejector can be held in the clamping position not just at one point, but at several points around the circumference. In practice, three holding devices evenly distributed around the circumference have proven to be effective. Each holding device can be assigned a release device so that several, in particular three, release devices can be provided accordingly. To ensure simultaneous release of all holding devices so that the ejector is not subjected to one-sided loading, the individual release slides can be connected to one another. For this purpose, the release slides can be connected to one another, for example via a release coupling element, in particular annular.The trigger coupling element can be located on the rear outer side of the base of the fall arrester and can be moved together with the trigger slides. Thus, if only one trigger slide is moved, this movement is transmitted to the other trigger slides via the trigger coupling element, ensuring simultaneous activation. The various trigger slides can thus be motion-coupled to one another.

[0048] The trigger coupling element can have two projections at its lower end, e.g., in the shape of ears. The cams of the two tensioning shafts can come into contact with the projections shortly before reaching the ejection position and then push the trigger coupling element backward in the tensioning direction upon transfer to the ejection position. Thus, by rotating the tensioning shaft, all the designated triggering devices can be actuated simultaneously by the trigger coupling element, thus reliably triggering the ejector.

[0049] Furthermore, with regard to the above-mentioned object, a vehicle, in particular a military land vehicle, is proposed with a weapon and a device arranged in the collecting position behind the weapon, wherein the device can be designed as described above. Advantageously, the device or in particular the collecting device is arranged on the weapon and is therefore fixed to the weapon. The collecting device can thus move together with the weapon so that, for example, when the weapon recoils, it does not have to be moved out of the weapon's path of movement. Rather, the device or the collecting device can recoil together with the weapon. The vehicle can have a hull and a turret arranged so as to be rotatable relative to the hull, wherein the weapon and the device can be arranged in the turret of the vehicle.The turret can have a particularly closable opening through which the shell casings of the projectiles fired by the weapon can be ejected from the vehicle via the device. In the ejection position, the device or the collecting device for this purpose can be arranged in the area of ​​the opening.

[0050] Further details and advantages of the invention will be explained in more detail below with reference to an exemplary embodiment shown in the schematic drawings.

[0055] When firing large-caliber projectiles from a barreled weapon of a military vehicle, a projectile casing in the form of the case base often remains in the weapon 100. Before firing the next projectile, the case base must first be removed from the weapon 100, for which purpose it is ejected rearward from the weapon 100. A device 10 is arranged behind the weapon 100 to collect the case base, with which the case base can also be ejected directly from the vehicle after it has been collected.

[0056] The heart of the device 10 is a cup-shaped collecting device 1 in the broadest sense with an ejector 2 arranged therein. The collecting device 1 can be moved back and forth between a collecting position A behind the weapon 100 and an ejection position W pivoted upwards relative to it via a mechanism described in more detail below. In the collecting position A, a cartridge case end ejected from the weapon 100 can be collected in the collecting device 1. The collecting device 1 can then be pivoted into the ejection position W, and the cartridge case end can be ejected from the collecting device 1 and also from the vehicle via the linearly movable ejector 2.

[0057] Only one common drive is required for both the movement of the collecting device 1 and the movement of the ejector 2 in order to eject the case base from the vehicle. This is made possible by the fact that the individual components of the device, which will be described in more detail below, are mechanically coupled to one another, so that the movement of the collecting device 1 can initiate the movement of all other components via the drive. In particular, the ejector 2 is coupled to the collecting device 1 in such a way that when the collecting device 1 is moved from the ejection position W to the collecting position A, it is automatically moved into a clamping position S, so that the ejector 2 then only needs to be triggered later, when the collecting device 1 has been moved back to the ejection position W. The individual components of the device 10 will now be described in more detail below.

[0058] The collecting device 1 essentially consists of two areas arranged one behind the other in the axial direction, namely a collecting area 1.1 and a receiving area 1.2. In the collecting position A, the collecting area 1.1 is located as close as possible to the weapon 100 or one end of the weapon barrel and ensures that the case base of the fired projectile can be collected. The collecting area 1.1 consists of two cylindrical shell-shaped sections located opposite one another with respect to the longitudinal axis of the collecting device 1, which are arranged spaced apart from one another in the circumferential direction so that openings of equal size are arranged on both sides between the two sections. This can also be clearly seen, for example, in the illustrations in Figs. 2a and 2b.

[0059] A receiving area 1.2 is arranged axially behind the catching area 1.1, in which the ejector 2 is guided for linear movement and in which the ejected case base can be received. In the catching position A shown in Figs. 1a to 1c, the ejector 2 has already been moved rearward into the clamping position S by the clamping device 5, which will be explained in more detail below, against the force of a spring assembly consisting of several springs 5.1. The illustration in Fig. 4c shows the ejector 2, which is located in the rear part of the catching device 1. It can also be seen that the springs 5.1 arranged between the ejector 2 and the base 1.21 of the catching device 1, which closes off the receiving area 1.2 to the rear, are compressed, so that the ejector 2 is pretensioned in the ejection direction F and is guided by the springs 5.1 is accelerated forward together with the cartridge case base in the ejection direction F when the ejector 2 is triggered. In order to hold the trigger 2 in the cocking position S, a holding device 7 is provided, which will be described in more detail below and which can be released via a trigger device 6 to trigger the ejector 2.

[0060] Both the catching area 1.1 and the receiving area 1.2 have a free diameter essentially adapted to the cross-section of the case base to be received, so that the essentially disc-shaped case base can rest as completely as possible on the circular surface of the ejector 2 and be accelerated evenly. When catching the case base, the catching device 1 is initially in line with the weapon barrel, which, according to the position shown in Figs. 1a to c, corresponds to a substantially horizontal orientation. The orientation of the catching device 1 in the catching position A is therefore also dependent on the elevation angle of the weapon 100. In this position, the ejector 2 is already retracted and is in the cocking position S. As can be imagined with regard to Fig. 4c, the collected case base then lies in front of the ejector 2 within the receiving area 1.2 of the collecting device 1.

[0061] In a next step, the collecting device 1 is then moved or pivoted upwards from the collecting position A into the ejection position W, as can be seen from a comparison of the illustrations in Fig. 1a - c with Fig. 2a - c. During this movement, the ejector 2 does not move, so that accordingly the case base is not moved relative to the collecting device 1. During the movement between the collecting position A and the ejection position W, the collecting device 1 is moved both translationally and rotationally. This movement is initiated via the trapezoidal rod 3, which can be clearly seen, for example, in the illustrations in Fig. 1a and 2a. The trapezoidal rod 3 essentially consists of two rods 3.1, 3.2 of different lengths, arranged parallel to one another in the collecting position A. These rods 3.1, 3.2 are pivotally mounted on one side on a plate-shaped mounting element 4, which is coupled to the recoiling part of the weapon 100. Thus, the entire catching device 1, together with the trapeze rod 3 and the mounting element 4, retracts along with the weapon 100 when a projectile is fired.

[0062] At the opposite end, the rods 3.1, 3.2 are pivotally connected to a lever 3.3, which in turn is firmly coupled to the fall arrest device 1. The distance between the two rods 3.1, 3.2 is smaller at the lever-side end than at the mounting element-side end.

[0063] These different distances, in combination with the different rod lengths, mean that the collecting device 1 is not only pivoted upwards when moving from the collecting position A to the ejection position W, but is also erected. Because the upper rod 3.2 is slightly longer than the lower rod 3.1, the lever 3.3 and thus also the collecting device 1 are tilted backwards when pivoted upwards, i.e. when moving from the collecting position A to the ejection position W, so that the case base can be ejected diagonally upwards out of the vehicle. When pivoted downwards, i.e. when moving from the ejection position W to the collecting position A, the collecting device 1 is then tilted accordingly in the opposite direction. Thus, the angle between the ejection direction F and the horizontal also changes during movement, as can be seen, for example, in Fig. 2b.

[0064] To ensure that the catching device 1 remains reliably positioned behind the weapon 100 when the weapon recoils and does not move unintentionally, the upper rod 3.2 is locked in the catching position A in a locking device 8 arranged on the mounting element 4. The locking device 8 represents a substantially U-shaped receptacle, which not only functions as a stop, but also prevents lateral movement of the rod 3.2 and thus also of the catching device 1. Furthermore, the locking device 8 can also be used, e.g., by means of a transverse pin, to completely prevent the rod 3.2 from moving. This is useful, for example, during fast marches when the weapon 100 is not in use but large vertical accelerations may occur due to uneven ground. Upward movement can also be prevented in this way.

[0065] To drive the arresting device 1 or the trapezoidal rod 3, a drive with a lifting cylinder is provided (not shown in detail in the illustrations). The lifting cylinder engages a laterally protruding coupling pin 3.4 of the lower rod 3.1 and can pivot the lower rod 3.1 up and down, thereby initiating the movements of the arresting device 1 described above. The drive is not arranged on the mounting element 4, but rather on the weapon 100, so that the reaction forces when a projectile is fired do not act on the drive. To solve this structurally, the drive can engage the coupling pin 3.4 via a jaw connection, which thus enables relative movement between the trapezoidal rod 3 or the rod 3.1 and the drive. When the weapon recoils, the coupling pin 3.4 thus automatically detaches from the drive or from the jaw of the drive. When the coupling pin 3.4 returns, it then moves independently back into the mouth of the drive, so that in the next step a movement of the collecting device 1 can be initiated again via the drive.

[0066] To ensure that the fall arrester 1 can be reliably moved behind the weapon 100 and also reliably absorb certain forces, the fall arrester 1 is not only coupled to the weapon 100 via a trapezoidal rod assembly 3, but two trapezoidal rod assembly 3 are provided, arranged on opposite sides. This can be seen, for example, in the perspective side view of Fig. 1a and also in the top view of Fig. 1c. The two trapezoidal rod assembly 3 are identically designed, so reference is made to the above in this regard. To enable uniform movement, corresponding drives can be provided on both sides of the weapon 100 or the fall arrester 1; however, additional drives are not required to operate the device 10.

[0067] The lower rod 3.1 is connected at its upper end to a tensioning shaft 5.2 which extends transversely to the rod 3.1 and which cannot be moved relative to the rod 3.2. The end of the tensioning shaft 5.2 can be clearly seen, for example, in the illustrations in Figs. 3a and 3b. By coupling the rod 3.1 to the tensioning shaft 5.2, the tensioning shaft 5.2 moves or rotates relative to the catching device 1 both when the catching device 1 is pivoted up and down. Arranged on the tensioning shaft 5.2 is a tensioning segment 5.3 designed as a pinion, which is connected in a rotationally fixed manner to the tensioning shaft 5.2 and which therefore also rotates relative to the catching device 1 when the catching device 1 moves. The clamping segment 5.3 is in contact with a tensioning chain 5.4, which is guided over the individual teeth of the clamping segment 5.3, so that a rotational movement of the clamping segment 5.2 relative to the collecting device 1 via the tensioning chain 5.4 is converted into a relative linear movement.

[0068] As can be seen, for example, from the illustration in Figs. 3a and 3b, the ejector 2 has radially projecting projection regions 2.1 that extend laterally through lateral recesses 1.3 in the collecting device 1 or in the receiving region 1.1. Outside the receiving region 1.1, these projection regions 2.1 are guided on a guide rail 1.4 that extends in the ejection direction F or in the clamping direction P, so that the ejector 2, guided by the guide rail 1.4, can be moved back and forth in a linear direction in the collecting device 1.

[0069] The laterally projecting projection areas 2.1 are now connected in the outer area to the tensioning chain 5.4, so that the ejector 2 can be moved or pulled backwards via the tensioning chain 5.4. The illustration in Fig. 4a initially shows the ejector 2 in the front end position, in which a case base has just been ejected and in which the catcher 1 is in the ejection position W. In this position, the tensioning chain 5.4 is essentially unwound from the tensioning segment 5.3 and is only in contact with the tensioning segment 5.3 with its rearmost chain links. In this position, the tensioning chain 5.4 thus extends parallel to the guide rail 1.4 and the projection area 2.1 rests against a damper 1.5 at the end of the guide rail 1.4.

[0070] If the catching device 1 is now transferred from the ejection position W to the catching position A, the tensioning shaft 5.2 rotates and the ejector 2 is moved backwards in the tensioning direction P via the tensioning chain 5.4 against the force of the spring 5.1 until it has reached the tensioning position S in the catching position A. The corresponding tensioning position S, in which a case base can then be received in the receiving area 1.2 of the catching device 1, can be seen in the illustration in Fig. 4c.

[0071] In order to hold the ejector 2 in the clamping position S, a holding device 7 is provided which is designed in the manner of a rocker and which engages in an engagement contour 2.2 of the ejector 2 in order to hold the latter in the clamping position S. Due to this positive connection between the holding device 7 and the ejector 2, the ejector 2 does not move despite the pretension of the springs 5.1 pressing it in the ejection direction F, but rather it is fixed in the clamping position S. The holding device 7 can be seen in the sectional view in Fig. 4c. In order to hold the ejector 2 as uniformly as possible around the circumference, three individual holding devices 7 are provided which are arranged evenly around the circumference of the collecting device 1 or the receiving area 1.2. Due to the cross-sectional views, only one of the three holding devices 7 can be seen in the illustrations in Figs. 4a to 4c.

[0072] Only when the catching device 1 has been moved from the catching position A to the ejection position W can the holding device 7 be pivoted out of the contour or engagement contour 2.2 of the ejector 2, so that the ejector 2 is then accelerated to eject the case base in the ejection direction F. The ejector 2 then shoots forward in a linear direction in the receiving area 1.1 until the lateral projection areas 2.1 reach the end of the guide rail 1.4 and are decelerated in the end position by the damper 1.5. The case base then flies out of the vehicle through the catching area 1.1 due to its mass inertia.

[0073] To actuate the holding device 7 so that it holds the ejector 2 in the clamping position S, no additional drive is required; rather, the device 10 is designed to be self-locking. This is achieved in such a way that the rear end of the holding device 7 projects into the receiving area 1.2 and into the path of movement of the ejector 2, so that the ejector 2 comes into contact with the rear part of the holding device 7 during a movement in the clamping direction P. When such contact is made, the end of the holding device 7 that comes into contact with the ejector 2 is pressed by the ejector 2 in a radial direction outwards, out of the path of movement of the ejector 2. Due to the rocker-shaped design of the holding device 7, this results in the front end of the holding device 7 being moved radially inwards and thus being pivoted into the engagement contour 2.2 of the ejector 2.

[0074] The illustration in Fig. 4b shows the position in which the ejector 2 contacts the rear part of the holding device 7. The ejector has therefore not yet fully reached the clamping position S. Upon further movement in the clamping direction, the holding device 7 is then pivoted as shown in Fig. 4c and the front end engages with the ejector 2. In this clamping position S, the ejector 2 is thus fixed by the holding device 7 and can then no longer be moved. It is therefore then also not necessary to exert a continuous force on the ejector 2 via the clamping chain 5.4 in order to hold it in the clamping position S.

[0075] With regard to the central axis of the collecting device 1, a snapper 7.1 is provided in front of the holding device 7 in the clamping direction P, which can be clearly seen in the illustrations in Figs. 4a to 4c. Just like the holding device 7, this snapper 7.1 is also present three times and distributed at a uniform circumferential distance from one another. The snapper 7.1 can also protrude into the free cross-section of the receiving area 1.2, as can be seen, for example, from the illustration in Fig. 4c. However, when the ejector 2 is moved in the clamping direction P, the snapper 7.1 is retracted or folded in. The snapper 7.1 is designed like a pivoting bevel that is inclined in the clamping direction S. Due to this design, the ejector 2 can be moved in the clamping direction P over the snapper 7.1, for which the snapper 7.1 is then pushed radially outwards out of the movement path via the ejector 2.However, in the event of a movement in the opposite direction, the latch 7.1 does not automatically pivot away; rather, due to its inclination, a movement of the ejector 2 in the opposite direction is prevented. In this respect, the latch 7.1 can also prevent an unintentional movement of the ejector 2 in the ejection direction F and thus act as a kind of blockade.

[0076] In addition, the snapper 7.1 can also ensure that the case base is in contact with the ejector 2 as the catching device 1 moves from the catching position A to the ejection position W, and that it does not accidentally fall out of the catching device 1 or become jammed, for example, during bumpy off-road driving. Rather, the axial distance between the snapper(s) 7.1 and the ejector in the clamping position S is approximately dimensioned such that the case base is positioned between the snappers 7.1 and the ejector 2 and is thus fixed.

[0077] Before the ejector 2 can be accelerated in the ejection direction A, it is not only necessary to pivot the holding device 7 so that it no longer engages with the ejector 2, but also to fold in the catches 7.1 and thus pivot out of the path of movement of the ejector 2. In order to move both the holding device 7 and the catch 7.1 accordingly, a triggering device 6 is provided, via which the ejector 2 can then be triggered accordingly to eject the case base. The structural design and function of the triggering device 6 will be explained in more detail below with reference to the illustrations in Figs. 4a to 4c.

[0078] The release device 6 initially has a retaining pin 6.2 extending in the axial direction, which can engage behind the holding device 7 in the clamping position S, so that the holding device 7 is prevented from moving and cannot be tilted into the position releasing the ejector 2. The retaining pin 6.2 rests radially inwardly on the rear end of the holding device 7, so that it blocks any movement of the holding device 7. This can be seen, for example, in the illustration in Fig. 4c.

[0079] In order to pull the retaining bolt 6.2 backwards so that it no longer blocks the holding device 7, but can be pivoted into the position where it no longer holds the ejector 2, the retaining bolt

[0080] 6.2 is coupled to a trigger slide 6.1, via which the retaining bolt 6.2 can be moved accordingly. The trigger slide 6.1 is arranged on the outside of the collecting device 1 so that it does not reduce the free space available inside the collecting device 1. Accordingly, the trigger slide 6.1 is also clearly visible in the perspective top views, e.g., in Fig. 1a or 2a, but also in Figs. 3a and 3b. Since each holding device 7 is assigned a trigger device 6, three trigger devices 6 are provided accordingly in the exemplary embodiment.

[0081] The trigger slides 6.1 are guided in a linear direction on the outside of the catching device 1 and can thus be moved back and forth parallel to the central axis of the catching device 1. The trigger slides 6.1 are movable against the force of tension straps 6.5, which can also be seen in the illustrations, so that when the trigger slides 6.1 are retracted, they are tensioned or stretched and pre-tension the trigger slide 6.1 forward, i.e., into the ejection position F. The retaining bolt(s) 6.2 are connected via a screw connection to an annular projection element 6.3, which is arranged in the rear area and thus outside the catching device 1. The projection element

[0082] 6.3 is plate-shaped and rests against a part of the trigger slide 6.1 that is guided parallel to the bottom of the collecting device 1, so that by retracting the trigger slide 6.1 the retaining bolt 6.2 can also be retracted and the retaining element 7 can thereby be released.

[0083] At the same time, when the release slide 6.1 is retracted, the catch 7.1 is also pivoted radially outwards, so that it is moved out of the path of movement of the ejector 2 and the path is thus cleared. When the release slide 6.1 has been pulled back far enough that the retaining pin 6.2 no longer prevents the holding device 7 from moving, the holding device 7 tilts backwards, so that the front end of the holding device 7 pivots out of the ejector 2. Since the catch(s) 7.1 have also been retracted, the ejector 2 can then freely spring forward, driven by the spring 5.1, and the case base arranged in front of the ejector 2 can be ejected.

[0084] In order to pull the release slide 6.1 backwards for release, no separate drive is required, but rather the release slide 6.1 is also coupled to the tensioning shaft 5.2, so that a relative rotational movement of the tensioning shaft 5.2 leads to the movement of the release slide 6.1 and then also to the automatic release of the ejector 2 when the ejection position W is reached. In terms of construction, the tensioning shaft 5.2 is equipped with a cam (not shown in the illustrations), which is arranged in such a way that it can pull the ejection slide 6.1 backwards shortly before the ejection position A is reached, so that the ejector 2 is then automatically released in the ejection position A.

[0085] To ensure that all existing trigger slides 6.1 are actuated or pulled backwards in the same direction, thus releasing all three holding elements 7 simultaneously, the trigger slides 6.1 are connected to one another via a trigger coupling element 6.4. The cams for moving the trigger slides 6.1 therefore do not have to be in direct contact with the trigger slides 6.1, but rather they can move all trigger slides 6.3 simultaneously via the trigger coupling element 6.4 and thus trigger the ejector 2. The trigger coupling element 6.4 has two downwardly projecting ears 6.41, which can be seen from the rear in the illustration in Fig. 3b. Each of the two tensioning shafts 5.2 can have a cam which, shortly before reaching the ejection position A when the collecting device 1 is pivoted upwards, press against the ears 6.41 from the front and thus basically in the tensioning direction P, thereby actuating the trigger coupling element 6.4 or the multiple trigger slides 6.1 Pull backwards in the same direction.

[0086] Therefore, no additional drive is required for either tensioning the ejector 2 via the tensioning device 5 or for triggering the ejector 2 via the triggering device 6. Instead, both processes are initiated by a rotational movement of the tensioning shaft 5.2. The tensioning shaft 5.2 also does not need to be actively driven; rather, due to the design of the trapezoidal rod 3, it is automatically rotated relative to the catch device 1 and thus also relative to the tensioning device 5 and the triggering device 6 when the catch device 1 moves. Therefore, a movement of the catch device 1 automatically leads to an actuation of the tensioning device 5, thus also to an actuation of the holding device 7 and finally to an actuation of the triggering device 6. All components can thus be moved and actuated solely by the drive of the trapezoidal rod 3. Reference numerals:
