Description

[0001] The invention relates to a carriage for a weapon, in particular a machine gun, comprising a weapon mount for holding the weapon and a mounting element for mounting the carriage on a vehicle. Furthermore, the invention relates to a vehicle with a hatch and a carriage.

[0002] Such mounts can, for example, be mounted in the roof area of ​​a military vehicle near a hatch, allowing the operator to manually aim and fire the weapon mounted in the mount's weapon receiver from an over-the-hatch position, with their upper body projecting out through the hatch opening. The actual weight of the weapon is borne by the mount, allowing the operator to concentrate on aiming and firing. This allows for greater precision compared to a weapon held freely in the hand, rather than on a mount.

[0003] To aim the weapon, it must be movable relative to the vehicle or relative to the mounting element permanently attached to the vehicle. This is possible by connecting the mounting element and the weapon mount in a movable, particularly rotatable, manner, so that the weapon, together with the weapon mount, can be pivoted back and forth around a vertical axis of rotation, which is usually located slightly away from the hatch.

[0004] Although such a swivel mount can generally engage targets in the area in front of the vehicle, the aiming range is limited due to the operator's limited mobility in the over-the-hatch position. To aim the weapon reliably, the operator's line of sight must be at least approximately aligned with the weapon barrel axis. With such a simple swivel mount, the azimuth aiming range can sometimes be well under 90 degrees.

[0005] The invention is based on the Aufgabe to specify a carriage for a weapon with which the weapon can be aimed over a larger aiming range.

[0006] This task is achieved in a carriage of the type mentioned above by gelöst that the weapon holder and the mounting element for moving the weapon held in the weapon holder are connected to each other via two pivoting arms.

[0007] The two pivot arms allow the weapon or weapon mount to be pivoted not only around a single axis of rotation, but also around multiple axes, which overall means that the weapon can be aimed over a wider angular range. To ensure that the line of sight and the weapon barrel axis remain approximately congruent, at least in the azimuth direction, the operator only needs to turn their head or turn around their own axis in the over-the-hatch position. Depending on the length of the pivot arms and the position of the mounting element relative to the hatch, aiming ranges of over 180 degrees can be achieved. Furthermore, the multi-axis pivoting movement of the weapon can also enable translational movement of the weapon, which can also facilitate aiming.

[0008] With regard to the carriage, it has also proven advantageous if one of the pivot arms is connected to the mounting element via a pivot bearing and the other pivot arm is connected to the weapon mount via a pivot bearing. The two pivot bearings can each enable a pivoting movement about an essentially horizontally oriented axis of rotation, so that each pivot bearing has a rotational degree of freedom. The mounting element can be firmly connected to the vehicle, in particular to the vehicle roof. For example, a screw connection can be provided for this purpose. The mounting element must be sufficiently stable, as it must not only absorb the weight forces of the weapon acting in the vertical direction, but also the acting torques, which are comparatively large, especially when the weapon is relatively far away from the mounting element due to the pivot arms.The recoil of the weapon also sometimes requires the absorption of high, impulsive forces.

[0009] Furthermore, it has proven advantageous if the two swivel arms are connected to each other via a swivel bearing.

[0010] Advantageously, three pivot bearings can be provided so that the weapon, together with the weapon mount, can be pivoted around three axes of rotation and can therefore also be moved translationally. To ensure sufficient stability, the mount can be designed in such a way that the pivot bearings only allow pivoting movement around one, in particular vertical, axis. Accordingly, the weapon can then only be pivoted and moved translationally in one plane via the mount, but not moved up or down. The mount can therefore allow movement of the weapon and the weapon mount in two translational degrees of freedom. In addition, the weapon mount can also be directed in elevation, which will be described in more detail below. The mount thus allows pivoting or rotational movement of the weapon with two degrees of freedom.

[0011] The rotation axes of the pivot bearings can be arranged parallel to each other and extend in a vertical direction. Each pivot arm can be pivotable in a plane, whereby the planes can be parallel to each other, so that both pivot arms can perform a full 360-degree rotation without interfering with each other. The two pivot arms can therefore be arranged offset in height from each other, and the pivot arm connected to the mounting element can be arranged below the pivot arm connected to the weapon mount. The pivot arms can essentially have an elongated or rod-shaped geometry. The pivot bearings can be arranged in the end regions of the pivot arms, resulting in a large range of motion.

[0012] Advantageously, the two pivot arms are approximately the same length, allowing the first and third rotation axes to be aligned. This has proven particularly advantageous with regard to azimuth lashing, which is described in more detail below.

[0013] With regard to the pivot bearing, it has proven advantageous if it has a pivot bearing which is connected on one side to one of the pivotally connected elements and on the other side to the other. In the case of the first pivot bearing, the first pivot arm can thus be connected to the mounting element via the pivot bearing. In the case of the second pivot bearing, the two pivot arms can be connected to one another via the pivot bearing, and in the case of the third pivot bearing, the second pivot arm and the weapon mount can be connected to one another. Each pivot bearing can thus have a corresponding pivot bearing. The pivot bearing can be a rolling bearing, e.g. a ball bearing, a spherical roller bearing, or a needle bearing. Depending on the force applied, the pivot bearing can also be designed as a plain bearing.Advantageously, the pivot bearing is secured in the axial direction, so that a reliable pivoting movement is ensured.

[0014] Furthermore, with regard to the pivot bearing(s), it has proven advantageous if the pivot bearing has a pivot pin that is non-rotatably connected to one of the pivotally connected elements, which is pivotally mounted in the other element via the pivot bearing. This design ensures a reliable and sufficiently stable pivot connection of the elements. The pivot pin can be arranged on the first pivot arm, and the pivot pin can be pivotally mounted in the mounting element. Furthermore, a pivot pin can be arranged on the second pivot arm and pivotally mounted in the first pivot arm via a pivot bearing. The weapon mount can be pivotally mounted in the second pivot arm via a pivot pin. The pivotable connection can therefore essentially be made possible by the respective pivot pin and the pivot bearing.

[0015] From a structural point of view, the pivot pin can have a substantially cylindrical shape and be designed as a rotating body. The axis of rotation can extend centrally through the pivot pin and thus coincide with its axis of symmetry. The immovable connection between the pivot pin and one of the elements, i.e. the first pivot arm, the second pivot arm or the weapon mount, can be ensured by a screw connection. The pivot pin can be flange-shaped for connection, at least in one section, so that it can be connected to the element using several screws. In order to secure the pivot pin in the axial direction in the pivot bearing, the pivot pin can have a shoulder via which it can be supported on the pivot bearing in the axial direction. In this respect, vertical forces can also be transmitted between the elements. On the other side of the pivot bearing, the pivot pin can have a securing element, e.g.A lock nut must be used to secure the bearing axially against the pivot. The locking element or lock nut can be screwed onto the pivot pin.

[0016] Furthermore, it has proven advantageous if one of the elements has a receptacle for pivotably receiving the pivot pin. The pivot pin can be pivotally received in the receptacle via the pivot bearing. The receptacle can be designed as a bore that can extend in the vertical direction. The pivot bearing can be secured in the receptacle in the axial direction. For example, the receptacle can have a shoulder against which the pivot bearing, in particular the outer ring of the pivot bearing, can rest. On the opposite side, the pivot bearing can be secured in the axial direction in the receptacle or in the element via a securing element, e.g. a securing ring, so that the latter cannot move in the axial direction.

[0017] The mounting element can have a corresponding receptacle in which a pivot pin firmly connected to the first pivot arm is received. The first pivot arm can then be rotated or pivoted about the first axis of rotation like a lever. On the other hand, the first pivot arm can have a receptacle for receiving the pivot pin firmly connected to the second pivot arm. In this respect, the second pivot arm can be rotated or pivoted about the second axis of rotation relative to the first pivot arm like a lever. Furthermore, the second pivot arm can have a receptacle for a pivot pin connected to the weapon mount in the end region opposite the pivot pin. The weapon mount can thus be rotated about the third axis of rotation.

[0018] According to an advantageous development, the pivot pin is designed in two parts. The two pivot pin parts can be rotationally coupled to one another so that the pivot pin can be rotated as a whole about the respective axis of rotation. The two-part design can be advantageous with regard to assembly, since one part can then be mounted in the recess from above and one part from below. The pivot bearing, in particular the inner ring of the pivot bearing, does not necessarily have to be secured axially relative to the pivot pin by a securing element, but the pivot bearing can be fixed axially via the two pivot pin parts. In particular, the two pivot pin parts can have a shoulder so that the inner ring of the pivot bearing can be fixed axially between the two shoulders.After positioning in the recess, the two pivot pin parts can be connected to each other via a screw connection. Advantageously, the pivot pin of the second pivot bearing can be designed in two parts, while the pivot pin of the first pivot bearing can be designed in one part.

[0019] To protect the pivot bearing, it has proven advantageous to provide a cover for the mount. This cover prevents dirt from penetrating the pivot bearing from above, or between the mount and the pivot pin, and then later into the pivot bearing area. The ingress of water can also be prevented or at least significantly reduced by appropriate seals in the cover area. The cover can be screwed onto the recess from above and connected to the first pivot arm in the area of ​​the first pivot bearing and to the second pivot arm in the area of ​​the second pivot bearing.

[0020] According to a particularly advantageous development of the invention, it is proposed that at least one of the pivot bearings has a braking device. Advantageously, at least the first and second pivot bearings each have a braking device, but all or just one of the pivot bearings can also have a braking device. The braking device can be used to brake a pivoting movement of the two elements pivotally connected to one another via the respective pivot bearing. The braking device thus makes it possible to brake the recoil forces acting from the weapon on the carriage, which increases precision. Even during continuous fire, the weapon can remain precisely aimed at the target to be engaged with comparatively little effort. Furthermore, it can be prevented that, for example, when the vehicle is driving over uneven ground, jerky vehicle movements are not transmitted unhindered to the weapon or the weapon mount.The weapon can therefore be held relatively steady even during bumpy rides without much effort.

[0021] With regard to the braking device, it has also proven advantageous if it can be used to brake, but not prevent, relative movement between the two elements connected to each other via the pivot bearing containing the braking device. The braking device therefore does not function as a locking mechanism that prevents or locks the pivoting movement of the elements, i.e., the mounting element, the two pivot arms, or the weapon mount, but rather merely slows down the movements. A locking mechanism could cause problems when aiming or firing accurately, as the locking mechanism would then have to be released again to re-position the weapon after firing.

[0022] It is particularly advantageous if the braking device is designed as a mechanical friction brake. Such a braking device can generate a frictional force that counteracts the movement of the elements connected to each other via the pivot bearing, thus slowing the pivoting movement. Another advantage of a mechanical friction brake is its very simple and error-prone design, which is particularly important in the military sector.

[0023] With regard to the braking device, it has also proven advantageous if the braking effect of the braking device can be adjusted using an adjustment device. The braking effect, or in the case of a friction brake, the friction force generated, can be easily adjusted to the outer boundary parameters using the adjustment device, so that sufficient, but not excessive, braking effect can be ensured at all times. For example, different operators may have different preferences with regard to braking effect, or different weapons or different cadences may require different settings. The vehicle, the vehicle speed, or the surface condition can also play a role in the adjustment. Advantageously, the braking effect can be manually adjusted by the operator using the adjustment device, so that it can be readjusted very easily and on the fly.

[0024] In a design development of the braking device, it has proven advantageous if the braking device has a first braking element and a second braking element, wherein one of the braking elements is rotationally coupled to one element and the other braking element is rotationally coupled to the other element, and wherein the two braking elements frictionally contact one another to generate a braking effect. Due to the connection to the pivotally connected elements, the two braking elements also move relative to one another, and their contact generates a braking effect or braking torque due to friction, which counteracts the pivoting movement. The two braking elements can therefore have friction surfaces that contact one another and slide frictionally against one another during a pivoting movement.

[0025] With regard to the braking elements, it has proven advantageous if one of the two braking elements is held in the receptacle in a rotationally fixed manner. This braking element is therefore arranged fixedly in relation to the other braking element and can brake the other braking element like a brake disc. The stationary first braking element can be arranged fixedly in the receptacle of the mounting element in the case of the first pivot bearing and fixedly in the receptacle of the first pivot arm in the case of the second pivot bearing. To prevent the first braking element from rotating about the corresponding axis of rotation during a pivoting movement, it can be positively connected in the receptacle or, depending on the pivot bearing, positively connected to the mounting element, to the first pivot arm or to the second pivot arm. The braking element can then have lugs projecting in the radial direction for this purpose, which lugs can be guided in corresponding recesses in the recess.Advantageously, the first brake element is arranged in the receptacle in a rotationally fixed manner, but it can also be arranged to be movable in the axial direction, which will be explained in more detail below. A corresponding connection can be realized via the protruding lugs and correspondingly designed recesses. To enable axial movement, the recesses can be designed as channels extending in the axial direction. The two brake elements can be annular, so that the pivot pin can extend centrally through the brake elements.

[0026] In order to ensure sufficient braking effect, it has proven advantageous if the braking device has a spring which presses the two braking elements together. The braking effect generated by the two braking elements depends not only on the coefficient of friction acting between the two friction surfaces of the braking elements, but also on the normal force with which the braking elements are pressed against one another or onto one another. The spring can provide a sufficient normal force which presses the two braking elements against or onto one another in the axial direction. The spring can be arranged between the pivot pin, in particular between a shoulder of the pivot pin and the first, upper braking element. The spring is advantageously rotationally decoupled from the pivot pin so that the pivot pin can rotate relative to the spring and the spring can be arranged stationary.The spring can then be arranged in a non-rotatable manner together with a braking element, in particular the upper, first braking element. Alternatively, however, the spring can also be rotationally coupled to the pivot pin, so that the spring can rotate together with the pivot pin relative to the first, upper braking element. The spring can be arranged above the first braking element and preload it downward toward the second braking element.

[0027] Furthermore, it has proven advantageous with regard to the spring if it is designed as a disc spring. This design allows the spring to exert a force that is distributed as evenly as possible across the surface of the brake element on the brake element pressed towards the other brake element, so that the two brake elements are pressed against each other or onto one another over as large an area as possible. This also prevents one-sided wear of the brake elements. Furthermore, it is advantageous if the spring is designed as a spring assembly, in particular as a disc spring assembly. This increases the axial compression of the spring and thus also improves the precision of the braking effect adjustment.

[0028] Advantageously, the two brake elements are accommodated in the holder so that they can move axially. The upper, first brake element can, as already described above, be guided in recesses in the holder and can therefore be moved axially but not rotated. The second brake element can be designed to rotate and can also move axially in the holder. Due to the vertical alignment of the axes of rotation, the two brake elements can therefore essentially be moved up and down in the recess in a linear direction. If the lower brake element is moved upwards against the second brake element, the latter can indeed give way due to the spring, but this tensions the spring and thus pressed the two brake elements against one another with a certain normal force.

[0029] To adjust the braking effect, one of the brake elements, in particular the lower, second brake element, can be moved in the axial direction by the adjustment device. The position of one of the brake elements, in particular the second brake element, can thus be adjusted via the adjustment device, and the normal force acting between the brake elements can thus also be varied. If the lower brake element is moved upwards against the second brake element via the adjustment device, the latter can deflect due to the spring, but this tensions the spring and thus presses the two brake elements against each other or toward one another with a specific normal force.

[0030] Furthermore, it has proven advantageous if a sliding bushing is arranged between the spring and the pivot pin. The spring can then be supported against the pivot pin via the sliding bushing. The spring can be stationary relative to the pivot pin, so that the sliding bushing acts as a sliding bearing, which is stationary together with the spring. Relative movement between the spring and the sliding bushing can thus be prevented. The sliding bushing can be connected to the pivot pin in the manner of a sliding bearing, so that rotational movement between the pivot pin and the sliding bushing is possible. The sliding bushing can be essentially cylindrical in shape, and the pivot pin can be mounted so that it can rotate in the sliding bushing. The sliding bushing can be supported axially relative to the pivot pin via a shoulder on the pivot pin, so that the sliding bushing cannot move in the axial direction.The spring can be supported on an axial end face of the sliding bushing so that the sliding bushing can act as an axial support for the spring.

[0031] From a structural point of view, the braking device can have a clamping bolt which is connected, in particular, at one end to the adjustment device and, in particular, at the opposite end, to one of the braking elements. The clamping bolt can be moved in the axial direction via the adjustment device and thus also move, in particular, the lower braking element. The clamping bolt and the braking element can therefore be axially coupled. The clamping bolt can extend through the pivot pin and, when the elements connected to one another via the corresponding pivot bearing are pivoted, can rotate together with the pivot pin about the axis of rotation. By arranging the adjustment device at one end of the clamping bolt, it can be accessible from the outside and can be easily reached by the person operating the weapon.

[0032] The adjustment device can have a nut, via which the clamping bolt can be moved in the axial direction. The nut can be screwed onto a thread on the end of the clamping bolt, so that turning the nut moves the clamping bolt in the axial direction and thus also moves one of the braking elements for adjusting the normal force. This design can be used in particular on the first pivot bearing. The nut can be supported on the pivot pin from above and is therefore immovable in the axial direction and easily accessible from the outside. The nut can be designed to rotate together with the clamping element, so that essentially the entire adjustment device can rotate with the pivot pin. The nut can be turned to move the clamping bolt or the braking element, e.g. using a tool such as a wrench.However, the nut can also be provided with a wheel or a lever so that the weapon operator can turn the nut by hand and without the use of additional tools. The nut can be designed as a cap nut and thus cover the top of the clamping bolt. This can also reduce the ingress of dirt. Furthermore, the nut can extend through the cover and a seal can be provided between the nut and the cover to prevent dirt from entering at this interface as well. Furthermore, the nut can also be connected integrally to the clamping bolt and the clamping bolt can be screwed into the pivot pin to different depths via the nut. This also allows the axial position of the braking element coupled to the clamping bolt to be adjusted and the braking effect can thus be varied.

[0033] To adjust the braking effect, one of the braking elements can be motion-coupled to the clamping bolt. Since the clamping bolt rotates together with the pivot pin during a pivoting movement, this is preferably the correspondingly rotating braking element. Therefore, there is no relative rotational movement between the clamping bolt and the connected braking element. Since the non-rotatable braking element can deflect against the force of the spring, the normal force can be adjusted very precisely and in small increments by turning the nut.

[0034] In an alternative embodiment, the adjustment device can have an adjustment screw, wherein one of the brake elements can be moved in the axial direction by rotating the adjustment screw. If the nut and the clamping bolt are designed as a single piece, they can represent a corresponding adjustment screw. This embodiment of the adjustment device can be used between the two pivot arms, in particular with the second pivot bearing. By rotating the adjustment screw, the bearing can move in the axial direction. The adjustment screw can be coupled in terms of movement in the axial direction to one of the brake elements, in particular to the second brake element, so that the brake element can also be moved in the axial direction by a corresponding rotation.

[0035] The adjusting screw can be screwed, in particular from below, into the pivot pin or the lower, second pivot pin part and can thus be rotationally coupled to the pivot pin. The adjusting screw can have a screw head and a screw shaft, wherein the screw shaft can be screwed into the pivot pin and rotated by turning the screw head. The screw shaft can correspond to the clamping bolt and the screw head can correspond to the nut. Analogous to the movement of the nut, the screw head can be rotated with a tool. A key difference compared to the adjustment device described with regard to the first pivot bearing is that the clamping bolt is not rotationally coupled to the nut, whereas the screw head and the screw shaft are integrally connected to one another.The screw head can rest against the second brake element, allowing it to be moved axially toward the other brake element by rotation. A washer can be provided to prevent damage to the surface of the brake element.

[0036] By screwing in from below, the risk of dirt getting into the area of ​​the braking elements is reduced. However, the adjustment screw, or its head, that is turned to adjust the braking effect is not visible. However, the weapon operator can easily feel the screw head by hand, making adjustment and turning the adjustment screw possible without any problems. With this design, the cover and the adjustment screw can be positioned opposite each other.

[0037] According to an advantageous development of the invention, the two brake elements are arranged between the spring and the head of the adjusting screw. The lower brake element can thus be moved by the axial movement of the adjusting screw. Through contact with the upper brake element, which is particularly stationary and can be moved axially against the force of the spring, the frictional or normal force acting between the brake elements, and thus also the braking effect, can be adjusted by rotating the adjusting screw.

[0038] Since the braking device can slow down the pivoting movement of the elements but cannot completely prevent it, it has proven advantageous to provide a locking device by means of which the two pivot arms can be locked relative to the mounting element. When the pivot arms are locked accordingly, pivoting movement about the corresponding axes of rotation, i.e. about the first and second axes of rotation, is no longer possible. The two pivot arms can be locked, for example, when the weapon is not in use, for example when cruising in peaceful areas or during heavy fire, where the over-the-hatch position is associated with a high level of danger. To ensure that the weapon is not pivoted unhindered about the axes of rotation in such situations, e.g. due to vibrations or movements of the vehicle, any corresponding movement of the pivot arms can be prevented by the locking device.

[0039] The locking device can be arranged on the mounting element such that the two pivot arms cannot be moved relative to the mounting element via the locking device. The mounting element can be fixedly and immovably mounted on the vehicle, in particular on the vehicle roof, so that the two pivot arms are also fixed relative to the vehicle.

[0040] According to an advantageous development, the weapon mount can also be locked via the locking device. In this respect, movement about the third rotational axis can also be reliably prevented by the locking device. The weapon mount can also be secured relative to the two pivot arms and the mounting element via the locking device. Movement of the weapon about a vertical axis is then no longer possible.

[0041] With regard to the locking device, it has proven advantageous if it has a locking element that can be moved back and forth between a locking position and a release position. In the release position, the elements, i.e., the first pivot arm and / or the second pivot arm and / or the weapon mount, cannot be fixed, and movement about the respective rotation axis can thus be possible. This represents the working position in which the weapon can be used and aimed in azimuth. In the locking position, such movement can be prevented, and the elements are thus fixed relative to the mounting element.

[0042] The locking element can be rotatable back and forth about a locking axis extending horizontally. In one end position, the locking element can be in the release position and in the other end position, correspondingly, in the locking position. The locking element can be rotatable back and forth approximately 90 degrees between these two end positions.

[0043] With regard to the locking axis, it has proven advantageous if it extends through one end of the locking element. This design allows the locking element to be pivoted back and forth about the locking axis like a locking lever. This design allows the required installation space for the locking element to be kept comparatively small, which becomes clear, for example, when compared with a locking element whose locking axis extends centrally through the locking element. The locking element can have an elongated or rod-shaped geometry overall. This also reduces the required installation space and space requirements.

[0044] Furthermore, it has proven advantageous if the locking element extends in a vertical direction in the locking position. This configuration allows the locking element to contact the elements arranged one above the other, i.e. the first pivot arm, the second pivot arm and possibly also the weapon mount, for locking purposes. The locking element can therefore be arranged in an upright position in the locking position. In the release position, the locking element can extend essentially in a horizontal direction and can therefore be arranged in a lying position. This arrangement means that in the release position, a pivoting movement is not impeded and, in particular, the lower, first pivot arm can thus be rotated over the locking element.

[0045] According to an advantageous development of the invention, the locking element is movable in the direction of the locking axis. The locking element can thus not only be pivoted back and forth about the locking axis between the locking and release positions, but can also be moved in the direction of the locking axis or in a linear direction. The advantages associated with a corresponding linear movement and the purpose of this movement are explained in more detail below.

[0046] To move the locking element, it can be connected to a handle. Using the handle, the locking element can be easily moved by hand by the weapon operator, both around the locking axis and longitudinally. Locking and releasing are thus very easy. The handle can be located at the end of the locking element and feature several radially projecting protrusions in the shape of a star, allowing the operator to perform both movements easily.

[0047] In order for the pivot arms to be locked via the locking device or locking element, they can each have a locking contour. In the locked position, the locking element can interact with the locking contours of the pivot arms and thereby prevent pivoting movement of the pivot arms. Advantageously, in the locked position, the locking element is positively coupled to the pivot arms and in particular also to the weapon mount, thus preventing relative movement. The locking contours of the first pivot arm can be arranged in the area of ​​the first pivot bearing and the locking contour of the second pivot arm can be arranged in the area of ​​the third pivot bearing. This enables the locking element to reliably reach the two locking contours in the locked position. The locking contours can therefore be arranged at the ends.

[0048] Furthermore, it has proven advantageous if the weapon mount has a locking contour for interacting with the locking element in the locked position. Via the locking contour of the weapon mount, the weapon mount can also interact with the locking element in the locked position, so that movement about the third rotation axis can then also be prevented. The locking contour of the weapon mount can also be arranged in the area of ​​the third pivot bearing, in particular directly above the locking contour of the second pivot arm.

[0049] With regard to the locking contours, it has proven advantageous if the locking contours are arranged one above the other in the locking position. Advantageously, the locking contours of the two pivot arms, and also advantageously the locking contour of the weapon mount, are arranged one above the other. The locking contours can be aligned one above the other, so that the locking element, which is particularly elongated, can contact all locking contours simultaneously for locking.

[0050] Furthermore, with regard to the locking contours of the pivot arms and, if applicable, also of the weapon mount, it has proven advantageous if the locking contours are designed as projections. This allows for reliable locking via the locking device. The locking contours can protrude radially with respect to the rotation axes, so that they can easily interact with the locking element. Advantageously, the locking contours are structurally identical or at least similar. For example, the locking contours can be designed as protruding contours with a rectangular base. Furthermore, the locking contours can be designed in the shape of strips or blocks.

[0051] To enable reliable locking, the locking element can have a locking contour that corresponds to the locking contours of the pivot arms. Advantageously, the locking contour is also designed to correspond to the locking contour of the weapon mount. This corresponding design ensures that the locked elements can no longer be moved when the respective locking contours interact. A positive connection is advantageously provided.

[0052] From a design point of view, it has proven advantageous with regard to the locking contour of the locking element if it is designed as a recess into which the locking contours, in particular the projections, of the pivot arms can engage. The locking contour of the weapon mount can also advantageously engage in the corresponding recess. The locking contours can thus be positively connected to one another in the locking position, which ensures reliable lashing or locking. The locking contour of the locking element can be divided into several sections, so that, for example, each locking contour of the pivot arms and, if present, also of the weapon mount, can engage in its own section. In an alternative design, it is also possible for the elements, i.e. the pivot arms and, if applicable,a recess is provided on the weapon holder and a corresponding projection is provided on the locking element side, which can engage in the recesses in the locking position.

[0053] Furthermore, it has proven advantageous if the mounting element also has a locking contour to which the locking element can be locked in the release position. The locking element can thus be fixed in the locking position via the locking contour of the mounting element, preventing it from moving accidentally in the release position. The locking element can be positively connected to the mounting element in the release position, and in order to pivot the locking element into the locking position, this locking mechanism must first be released.

[0054] With regard to the movement of the locking element, it has proven advantageous if it is mounted for linear movement in the direction of the locking axis. In order to interact with the locking contours of the pivot arms and the weapon mount, the locking element can be moved linearly in the direction of the corresponding locking contours. To release the fixation of the locking element to the mounting element and pivot it into the locked position, the locking element can be moved linearly away from the locking contour of the mounting element, so that the locking contours disengage.

[0055] In order to move the locking element accordingly, it can be mounted on a bolt for linear movement. The locking element can be pivoted back and forth about the locking axis together with the bolt between the locked position and the release position. For linear movement, the locking element can be mounted on the bolt for linear movement. Furthermore, it is also possible for the locking element to be moved together with the bolt in the direction of the locking axis. The bolt can be mounted in the mounting element for rotation, in particular via two pivot bearings. The locking axis can correspond to the longitudinal axis of the bolt and this can extend accordingly through the mounting element or through the housing of the mounting element. The first axis of rotation and the locking axis can be arranged skewed to one another. In the locked position, the first axis of rotation and the third axis of rotation can be arranged congruent with one another orthe two swivel arms can be arranged in such a way that the two axes of rotation are congruent with each other.

[0056] Furthermore, it has proven advantageous if the locking element can be moved in the direction of the locking axis against the force of a spring. The spring can preload the locking element in one direction, so that it can then be moved in one direction against the force of the spring, particularly by hand, and in the opposite direction by the force of the spring.

[0057] In order to ensure a reliable connection of the locking contours in both the locking position and the release position, it has proven advantageous if the locking element is pre-tensioned into a detent position by the spring in both the locking position and the release position. In the detent position, movement of the locking element can be prevented, so that in order to move the locking element from the release position to the locking position or from the locking position to the release position, it must first be moved against the force of the spring. Furthermore, the spring ensures that the locking contour of the locking element automatically engages with the other corresponding locking contours when the locking position and the release position are reached. In this respect, reliable locking of the pivot arms and, if necessary,both the weapon holder in the locking position and the locking element in the release position are ensured.

[0058] According to an advantageous development of the invention, the locking element has a stop area to simplify locking. The stop area can ensure that the locking element cannot be rotated beyond the locking position, since the locking contours of the pivot arms can strike the stop of the locking element in the locking position. Furthermore, the pivot arms and, if applicable, the weapon mount can be easily positioned correctly using the stop area so that their locking contours can engage with the locking contour of the locking element. If the locking contours of the pivot arms and the weapon mount are not yet aligned, they can run into the stop area when the locking element is moved into the locking position, or they can be pressed against the stop area by hand and thus correctly aligned.The stop area can extend over the entire length of the locking contour of the locking element. From a structural point of view, the stop area can be designed as a projection that protrudes axially on one side relative to the locking contour of the locking element with respect to the locking axis.

[0059] It is advantageous if the weapon cannot be moved in the azimuth direction relative to the weapon mount, so that the azimuth lashing of the swivel arms and the weapon mount prevents the weapon from being moved in the azimuth direction.

[0060] In order to reliably hit targets with the weapon, it is generally necessary to be able to point it not only in azimuth but also in elevation. For this purpose, the weapon mount can be provided with an elevation bearing and a weapon mount that is connected to the elevation bearing and can pivot about an elevation axis. The weapon and the weapon mount can be pointed in elevation via the elevation bearing, so that targets at different distances and in particular at close range can be reliably engaged. The elevation bearing can be connected to the second pivot arm via the third pivot bearing and can therefore rotate about the third pivot axis. From a structural point of view, the elevation bearing can have two carriages that extend vertically parallel to one another, between which the weapon mount can be pivotably suspended.For a pivoting connection, the weapon mount can be designed with two laterally projecting pins that can be pivotally mounted in correspondingly designed holes in the two cheeks. The weapon mount can thus be pivotally suspended between the two cheeks. The locking contour of the weapon mount can be arranged on the elevation bearing, so that the locking device can prevent rotation of the elevation bearing in the azimuth direction.

[0061] Furthermore, it has proven advantageous with regard to weapon mounting if the weapon can be held in the weapon mount without any play. This design prevents the weapon from moving relative to the weapon mount, or only to a very limited extent. Thus, when the weapon mount is secured, the weapon is also secured accordingly. Furthermore, means can be provided that enable the weapon to be mounted with as little play as possible. These can also function as a type of adapter, allowing for the mounting of different weapons without any play.

[0062] Although the locking device can ensure reliable locking and also prevent the weapon from being moved in azimuth, the weapon can still be moved in elevation in the weapon mount. Since it is also expedient to prevent corresponding movement in elevation, it has proven advantageous for the weapon mount to have an elevation lock with which the weapon mount can be locked in elevation. The weapon mount can thus be tightened in azimuth using the locking device described above and also in elevation using the elevation lock. By holding the weapon in the weapon mount with as little play as possible, the weapon can also be tightened accordingly and can then move neither in azimuth nor in elevation.

[0063] From a design perspective, it has proven advantageous if the elevation lock has a lever pivotally connected to the weapon mount and a locking point on the elevation bearing side, whereby the lever can be connected to the locking point for locking. When the lever is connected to the locking point, the weapon mount can no longer be moved in the elevation direction. By connecting the lever to the locking point, in addition to the pivotable coupling between the elevation bearing and the weapon mount, a further connection is enabled, and the weapon mount can then no longer be moved in elevation. The lever can be pivotable about an axis parallel to the elevation axis, and the locking point can be arranged away from the elevation axis, which enables reliable lashing of the weapon mount.The lever can be positively connected to the locking point to fix the weapon mount relative to the elevation bearing.

[0064] With regard to the connection between the lever and the locking point, it has proven advantageous if the lever can be locked to the locking point. A locking connection represents a reliable connection that can also be easily released, especially by hand. Advantageously, the lever automatically locks to the locking point upon reaching it. From a structural point of view, the locking point can be designed as a receiving bushing into which the lever can engage or lock.

[0065] The lever can have a bolt that can be moved, in particular via a handle, whereby the bolt is preloaded by a spring and can automatically lock with the locking point upon reaching it. The bolt can thus be moved via the handle against the force of the spring to release the locking connection.

[0066] With regard to weapon mounting, it has proven advantageous if the weapon can be detachably connected to the weapon mount. This design allows for easy exchange of the weapon and also the use of different weapons or different weapon types. For example, different weapons can be used depending on the combat situation. With regard to maintenance and repair, it has also proven advantageous if the weapon can be detached and disassembled from the weapon mount as easily as possible.

[0067] To connect the weapon to the weapon mount, it has proven advantageous to provide a weapon fixation device by which the weapon can be secured in the weapon mount. It is not absolutely necessary for the weapon mount to be adjustable in elevation; rather, the weapon fixation can be provided independently of the adjustability in elevation and thus also of the elevation bearing. If the weapon is fixed in the weapon mount by the weapon fixation, the weapon cannot be moved relative to the weapon mount, or only to a very limited extent. It is advantageous to provide two weapon fixations to fix the weapon so that the weapon can be detachably connected to the weapon mount at two points. Forces can then be transferred from the weapon to the weapon mount via the weapon fixation or fixations, and via the elevation bearing and the pivot arms to the mounting element.This also prevents the weapon from becoming distorted due to the recoil forces that occur when a shot is fired.

[0068] With regard to the connection between the weapon and the weapon mount, it has proven advantageous if the weapon is connected to the mount via a positive-locking mechanism. A positive-locking connection can achieve reliable fixation and can sometimes even transmit considerable forces.

[0069] According to an advantageous development of the invention, the weapon holder can have two vertically extending retaining cheeks. The retaining cheeks can extend laterally around the weapon and thus encompass it. The retaining cheeks can secure the weapon in such a way that it cannot move to the left or right, or can only move to the smallest possible extent. The two retaining cheeks can thus rest against the weapon, particularly laterally. The retaining cheeks can extend essentially in a parallel direction and be opposite one another with respect to the weapon arranged between the retaining cheeks.

[0070] With regard to weapon fixation, it has proven advantageous to have a fixing bolt. The fixing bolt can extend through the two retaining cheeks and through the weapon, thus enabling reliable fixation of the weapon. To allow the fixing bolt to penetrate the weapon and the retaining cheeks, the weapon can have corresponding holding recesses, which can be designed like holes. These can extend transversely through the weapon itself or through an intermediate element or adapter connected to the weapon. The key factor here is that the fixing bolts can fix the weapon in the weapon mount.

[0071] To ensure that the fixing bolt can also penetrate the holding cheeks, these can each have at least one recess. The fixing bolt can thus extend through the recesses in the holding cheeks and the holding recesses of the weapon. It is not absolutely necessary for the fixing bolt to penetrate both recesses completely; it can be sufficient if it protrudes a small amount into the recesses to prevent radial movement of the bolt. Two recesses can be arranged in pairs in the opposite holding cheeks. If the weapon is correctly positioned in the weapon mount, the two paired recesses and one holding recess can be aligned so that the fixing bolt, in particular a straight one, can be inserted through one recess and the holding recess and reach into the other recess.

[0072] According to a further advantageous embodiment, at least one recess, preferably at least two opposing recesses, have a cross-section that is larger than the cross-section of the fixing bolt. This embodiment allows the fixing bolt to move in the recess, thereby creating a certain tolerance compensation. The recess or the two opposing recesses can, for example, be designed as elongated holes extending in a horizontal direction. The holding recesses preferably have a cross-section that essentially corresponds to the cross-section of the fixing bolt, so that the weapon and the fixing bolt cannot be moved relative to one another in the radial direction of the fixing bolt. Rather, the tolerance compensation via the recesses means that the holding recesses of the weapon do not have to be arranged with absolute precision.This is also due to the fact that the weapon heats up and expands during firing, which can affect the position of the retaining recesses. This prevents jamming between the weapon and the locking pins or the weapon mount. However, it is advantageous if only one pair of recesses has a slightly larger cross-section than the locking pin, and the cross-section of the other pair is adapted to the locking pin. One pair of recesses can thus function radially like a fixed bearing, while the other can function radially like a loose bearing.

[0073] Furthermore, it has proven advantageous if the weapon fixation has a lock for locking the fixing bolt. This lock ensures that the fixing bolt is reliably held in position and is not accidentally moved in the axial direction. The locking mechanism can be used to lock the fixing bolt to the outside of a retaining cheek of the weapon mount. The fixing bolt can thus first be inserted axially into the recess of a retaining cheek and through the retaining recess and then locked in the inserted position via the lock. The locking mechanism can prevent the fixing bolt from becoming loose and accidentally moving in the axial direction, for example during bumpy off-road driving. In order to pull the fixing bolt out of the retaining recess of the weapon to release the weapon, the lock must first be released or unlocked.

[0074] With regard to the locking mechanism, it has proven advantageous to use a bayonet lock. A bayonet lock provides a simple, reliable, positive connection. The locking pin can be locked to the weapon mount or a retaining flange of the weapon mount using the bayonet lock, particularly by hand. To do this, the locking pin can first be inserted and then rotated, creating a positive connection.

[0075] Furthermore, it has proven advantageous if the locking bolt has a handle at the end, which allows the bolt to be moved manually. Using the handle, the operator can move the locking bolt axially by hand, i.e., move it into the recesses of the weapon mount or the weapon's holding recess, or pull it out again, as well as rotate the locking bolt around its longitudinal axis for locking. The handle can be designed as a ring, which simplifies both axial and rotary movement by hand.

[0076] According to a structural development of the invention, it is proposed that the locking mechanism comprise a first locking element, in particular on the fixing bolt side, and a second locking element, in particular on the weapon mount side, wherein the two locking elements cooperate to lock the fixing bolt, in particular interlocking with one another. When the two locking elements cooperate accordingly or, in particular, interlock, the fixing bolt is connected via the fixing bolt-side locking element to the weapon mount side locking element and thus also to the weapon mount and is no longer movable in the axial direction.

[0077] With regard to the two locking elements, it has proven advantageous if the first locking element has a locking projection projecting in the radial direction, which can engage behind a rear grip of the second locking element for locking. When the projection is pivoted into the rear grip by rotating the fixing bolt, the two locking elements are locked together and the fixing bolt can then no longer be moved in the axial direction. In order to move the fixing bolt in the axial direction and release the fixation of the weapon, the two locking elements must first be disengaged again. To ensure reliable locking, two locking projections can be provided, each of which is designed to project laterally or in the radial direction with respect to the fixing bolt.Additionally, two rear grips can be provided, so that when the fixing bolt is turned, a locking projection can engage with one of the two rear grips. The acting forces can thus be distributed between the two locking projections, which improves overall durability.

[0078] With regard to the structural design of the second locking element, it has proven advantageous if, to form the rear grip, it has a base element, in particular a plate-shaped one, and a projection arranged at a distance from the base element. The projection can extend substantially parallel to the base element, and the rear grip can be arranged between the base element and the projection. The first locking element or the locking projection can be inserted between the base element and the projection by rotation, so that the fixing bolt is then fixed in the axial direction. The base element can be mounted flat on the outside of the retaining cheek and have a recess which corresponds to the recess in the retaining cheek and is arranged congruently with it. The projection can extend parallel to the retaining cheek.Furthermore, two projections can be provided, which can be positioned point-symmetrically opposite one another with respect to the longitudinal axis of the fixing bolt. Thus, one projection can extend vertically upwards and the other downwards. The two projections also form two recesses into which the locking projections of the first locking element can engage.

[0079] According to an advantageous development of the invention, it is proposed that the projection has an angled portion, particularly at the end, which can engage behind the first locking element. The angled portion can extend essentially at a right angle and thus in the direction of the base element. The angled portion enables a push-to-close and a push-to-open function, so that the handle must first be subjected to a compressive force for both locking and unlocking, which compresses the spring. When the locking projection of the first locking element is in the rear engagement and the angled portion engages behind the locking element, rotation of the fixing bolt is prevented. The fixing bolt is thus secured against rotation by the locking mechanism.To unlock, the first locking element must first be moved against the force of the spring until it can no longer be engaged by the angled part and can therefore be turned back.

[0080] Furthermore, it has proven advantageous if the first locking element is connected to the handle. The first locking element can be cup-shaped and function as a receptacle or guide for the spring, which can be arranged in the first locking element or in the cup-shaped region of the first locking element. The spring can thus be covered by the first locking element or arranged within the first locking element, which protects the spring. The two locking projections can be designed as tabs projecting in the radial direction. The locking projections can extend radially away from the cup-shaped section of the locking element. The fixing bolt can extend through the spring and also through a corresponding recess in the first locking element and be connected to the handle.The first locking element can be directly connected to the handle, so that in the locked position, basically only the handle protrudes laterally from the weapon mount or the retaining cheek.

[0081] According to an advantageous development of the invention, a spring is provided, which is arranged between the handle and a pressure plate. The spring can thus be supported on one side against the pressure plate and on the other side against the handle and / or the first locking element. The pressure plate can be arranged on the fixing bolt so that it can move linearly in the axial direction. From a structural point of view, the pressure plate can be designed as a disc or an annular disc, and the fixing bolt can extend centrally through the pressure plate.

[0082] According to an advantageous development, the pressure plate is movable against the force of the spring during locking. The pressure plate can have a larger diameter than the recess in the holding cheek or in the second locking element, so that the pressure plate comes into contact with the holding cheek or with the base element when the fixing bolt has been inserted sufficiently far. Advantageously, in this position the fixing bolt already extends through the holding recess of the weapon. When the pressure plate rests against the holding cheek or the second locking element, a pressure force on the handle can move the handle, together with the fixing bolt and the first locking element, further in the direction of the holding cheek. The relative movement between the handle and the pressure plate can tension the spring. If the spring is not yet tensioned, rotation of the handle orof the fixing bolt can be prevented because the locking projection hits the angled portion of the second locking element when rotated and thus cannot be moved into the rear grip. Only when the spring has been compressed can the locking element pass the angled portion when rotated and engage the rear grip. If the pressure force is then removed, the locking projection can move back a little in the axial direction due to the force of the spring so that it is then engaged by the angled portion. In this position the handle can then no longer be turned. To unlock the handle, a pressure force must first be applied to the handle again until the locking projection can be moved past the angled portion when rotated and back into the unlocked position. In this respect, the two locking elements can be locked together via the spring-loaded pressure plate.In particular, the locking projection can snap behind the bend.

[0083] With regard to the object mentioned at the outset, a vehicle with a hatch and a carriage for a weapon is further proposed, wherein the weapon can be positioned via the carriage in such a way that an operator can operate the weapon in an over-the-hatch position and wherein the carriage is designed according to one of the preceding claims.

[0084] The two pivoting arms allow the weapon to be aimed in azimuth over a large range. It can therefore be provided that the mounting element, via which the carriage can be connected to the vehicle, is arranged away from the hatch. The weapon can therefore be moved from a position away from the hatch, in which the weapon is then not in use, to a position near the hatch, where the operator can aim and fire the weapon. Arranging the mounting element away from the hatch can offer advantages, for example compared to a turntable mount, as it creates significantly more space in the hatch area, particularly when the weapon is pivoted away and not in use. The hatch can be a roof hatch, and when the weapon operator is in the over-the-hatch position, their upper body can protrude through the hatch so that they can operate the weapon.The weapon is advantageously positioned essentially in front of the operator and in the middle area of ​​his upper body.

[0085] Further details and advantages of the invention will be described in more detail below with reference to the exemplary embodiments shown in the drawings. In these drawings: Fig. 1 a perspective side view of a vehicle with a mounted gun carriage; Fig. 2 a perspective view of the vehicle according to Fig. 1 from a different angle; Fig. 3a a perspective view of the carriage with a weapon; Fig. 3b a side view of the carriage in a locked position; Fig. 4 a sectional side view of a pivot bearing that connects the first pivot arm to the mounting element; Fig. 5 a sectional side view of a pivot bearing that connects the two pivot arms to each other; Fig. 6a, b perspective side views of a locking device in a locked position; Fig. 7a, b perspective side views of the locking device in a release position; Fig. 8 a perspective detailed view of a locking element of the locking device; Fig. 9a, b an elevation lock in a perspective side view in two different positions; Fig. 10 a perspective exploded view of a weapon fixed in the weapon mount via a weapon fixation; Fig. 11a-d various views of the weapon fixation in different positions; Fig.12a, bPerspective detailed views of the weapon fixation. .

[0086] The representation of the Fig. 1 shows a military vehicle 102 in a perspective side view. The vehicle 102 has a hatch 103 in the roof area, and a person is in an over-the-hatch position, i.e., the upper body at least partially penetrates the hatch 103 and can directly observe the surroundings. A gun carriage 100 is attached to the roof of the vehicle 102, which is arranged slightly away from the hatch 103 so that it does not obstruct the person in the over-the-hatch position.

[0087] The carriage 100 carries a weapon 101, which can be pivoted and aimed via the carriage 100. The design of the carriage 100, described in more detail below, enables the person or operator of the weapon 101 to easily and reliably aim it over the largest possible angular range. The person only needs to rotate around their own axis within a certain range, but can otherwise remain centered in the hatch opening. Fig. 2 shows the carriage 100 with the weapon 101 mounted in it from a different angle.

[0088] The basic structure of the Lafette 100 is, for example, based on the perspective representation of the Fig. 3a , can be seen. The gun carriage 100 essentially consists of a mounting element 1, two pivot arms 2, 3 and a weapon mount 20. The mounting element 1 represents the actual base of the gun carriage 100 and is firmly connected to the roof of the vehicle 102 via several screw connections. Via a first pivot bearing 10.1, the structure of which will be explained in more detail below, the fixed mounting element 1 is connected to a first pivot arm 2 which is arranged such that it can pivot relative to the vehicle. In the opposite end area, the first pivot arm 2 is connected via a second pivot bearing 10.2 to a second pivot arm 3, which in turn is connected at its opposite end via a third pivot bearing 10.3 to a weapon mount 20 in which the weapon 101 is received. The weapon 101 is thus also rotated about the rotation axes D1, D2, D3 of the pivot bearings 10 via the three pivot bearings 10.1, 10.2, 10.3.1, 10.2, 10.3 can be directed in azimuth.

[0089] In addition, the weapon can also be aimed in elevation, so that it can reliably engage targets at different distances from the vehicle 102. The elevation axis E is shown in both the representation of the Fig. 3a as well as in the Fig. 3b can be seen. In order to pivot the weapon 101 in elevation about the elevation axis E, the weapon mount 20 has an elevation bearing 21 and a weapon mount 22, which is pivotally suspended between two cheeks 21.1, 21.2 extending parallel to one another. The weapon mount 22 has two laterally projecting pins, which are arranged in corresponding recesses in the two cheeks 21.2, 21.2 and thus enable a pivoting movement about the elevation axis E in the manner of a cradle. The elevation bearing 21 arranged below the weapon mount 22 is connected to an end region of the second pivot arm 3 via the third pivot bearing 10.3.

[0090] In the presentation of the Fig. 3a The two swivel arms 2, 3 are arranged at an angle to each other, so that basically a swivel movement, starting from the one shown in the illustration of the Fig. 3b shown starting position, has taken place around all three axes of rotation D1, D2, D3. These pivoting movements, as well as the comparatively long pivot arms 2, 3, allow the weapon 101 to be pivoted over a very large angular range. Furthermore, the multiple axes of rotation D1, D2, D3 ensure that the weapon 101 can also be moved translationally over a large range, which is why the mounting element 1 does not have to be arranged in the immediate vicinity of the hatch 103, but can also be arranged away from the hatch 103.

[0091] The representation of the Fig. 3b now shows the carriage 100 in an initial position or in a lashed position. The two pivot arms 2, 3, which are essentially the same length, are arranged parallel to one another so that the first axis of rotation D1 and the second axis of rotation D3 are congruent. In addition, the weapon 101 or the barrel of the weapon 101 is arranged parallel to the two pivot arms 2, 3 so that the entire carriage 100 with the held weapon 101 takes up as little space as possible. In order to fix the carriage 100 or the movable elements of the carriage 100 in this position so that they do not move uncontrollably, for example during fast off-road travel, two different lashing or locking devices are provided. The two pivot arms 2, 3 and also the weapon mount 20 orThe elevation bearing 21, which is rotatable about the third axis of rotation D3, can be locked in azimuth, so that the elements can no longer be moved relative to the mounting element 1 about the vertical axes of rotation D1, D2, D3. The second locking device, designed as an elevation lock 23, can prevent an elevation movement of the weapon 101 or the waffle holder 22 relative to the elevation bearing 21. The structural design and function of the locking devices 23, 30 will be explained in more detail below. First, however, the illustrations in FIGS. Fig. 4 and Fig. 5 the structure of the two pivot bearings 10.1 and 10.2 will be described in more detail.

[0092] What both pivot bearings 10.1, 10.2 have in common is that they allow a pivoting movement about a vertical axis of rotation D1, D2. Furthermore, both pivot bearings 10.1, 10.2 have a braking device 15 that slows down the relative pivoting movements of the pivotally connected elements. The braking device 15 thus ensures that the weapon 101 can remain aimed at a target by hand, even at high rates of fire, with comparatively little effort. Furthermore, the braking device 15 also has advantages with regard to the driving movements of the vehicle 102. This is because the braking device 15 reduces the impact on the weapon 101, which both increases precision and reduces the force required to aim and stabilize the weapon. However, locking cannot be achieved via the braking device 15; instead, the two locking devices 23, 30 are provided for locking.

[0093] The representation of the Fig. 4 shows the first pivot bearing 10.1, which connects the first pivot arm 2 to the mounting element 1, in a sectional view. The first pivot arm 2 is firmly screwed to a pivot pin 12, which extends from the pivot arm 2 in the axial direction downwards into the mounting element 1. The mounting element 1 has a substantially cylindrical receptacle 1.1, in which a pivot bearing 11 designed as a rolling bearing is arranged in an axially secured manner. The pivot bearing 11 rotatably connects the pivot pin 12 to the mounting element 1, with the corresponding axis of rotation D1 running centrally through the pivot pin 12.

[0094] To ensure that the pivot bearing 11 can be supported axially in the mounting element 1 or in the receptacle 1.1, the mounting element 1 has a radially inwardly projecting shoulder 1.2 on its inner side, on which the pivot bearing 11 can be supported with an outer ring. To also secure the pivot bearing 11 in the receptacle 1.1 in the opposite direction, a retaining ring 13.1 is provided, which clamps the pivot bearing 11 or the outer ring of the pivot bearing 11 in the receptacle 1.1 of the mounting element 1, preventing it from moving axially.

[0095] The pivot pin 12 is now in contact with the inner ring of the pivot bearing 11, which also has a shoulder 12.1 for axial support. Below the pivot bearing 11, the pivot pin 12 is axially fixed by a lock nut 13, so that the pivot pin 12 cannot move axially relative to the inner ring of the pivot bearing 11. The first pivot arm 2 is thus secured in the mounting element 1 via the corresponding pivot bearing 11, so that axial movement is not possible, or the pivot pin 12 cannot be lifted upwards out of the mounting element 1. During a pivoting or rotating movement about the first rotation axis D1, the first pivot arm 2 rotates together with the pivot pin 12 and the inner ring of the pivot bearing 11 relative to the outer ring of the pivot bearing 11 and the mounting element 1 screwed to the vehicle 102.Rolling elements are arranged between the two rings of the pivot bearing 11, which enable a corresponding rotational movement.

[0096] The braking device 15 essentially consists of two braking elements 19, 19.1 which rub against each other and are arranged in the lower area of ​​the receptacle 1.1. The first braking element 19 is arranged non-rotatably in the receptacle 1.1, for which purpose it is connected to the Fig. 4 cannot engage with the mounting element 1 using the projections shown. However, movement in the axial direction of the first braking element 19 is possible. The second braking element 19.1 is arranged below the first braking element 19 and rests flat against it. Both braking elements 19, 19.1 essentially have an annular geometry and each have a diameter that corresponds to the free diameter of the receptacle 1.1 at the corresponding location, so that they rest against the mounting element 1 at their outer edge.

[0097] The second brake element 19.1 is rotatable together with the pivot pin 12. Thus, during a pivoting movement of the first pivot arm 2, friction occurs between the two brake elements 19, 19.1, which counteracts the acting torque and thus slows the pivoting movement. The braking effect depends primarily on the friction force acting between the two brake elements 19, 19.1, which in turn depends on the normal force acting in the axial direction and compressing the brake elements 19, 19.1.

[0098] The normal force, i.e. the force with which the second braking element 19.1 is pressed onto the first braking element 19, can now be adjusted manually via an adjusting device 17, so that the braking effect can be easily varied even when the carriage is in use. For this purpose, the lower braking element 19.1 can be moved in the axial direction, for which purpose it is connected to a clamping bolt 16 extending through the pivot pin 12. The clamping bolt 16 is connected at the upper end to the adjusting device 17, via which the clamping bolt 16 can move together with the second braking element 19.1 in the axial direction. The clamping bolt 16 is slightly widened at the lower end, i.e. in the connection area with the second braking element 19.1, as shown in the illustration of the Fig. 4 can be seen. In a corresponding manner, the pivot pin 12 is also conically widened in the lower region of its central recess, so that the clamping bolt 16 can be moved up and down in the pivot pin 12.

[0099] In order to move the clamping bolt 16 accordingly, it has a thread at its upper end, on which a nut 17.1 is rotatably arranged. The nut 17.1 is arranged as shown in the Fig. 4 designed as a cap nut and rests on the top side of the pivot pin 12. Since the nut 17.1 cannot move in the axial direction due to its support on the pivot pin 12, rotation of the nut 17.1 moves the clamping bolt 16 in the axial direction, thus pulling or clamping the lower brake element 19.1 against the upper brake element 19.

[0100] The first brake element 19 rests on the side opposite the second brake element 19.1 against a spring 18 designed as a disc spring. When the second brake element 19.1 is thus pressed against the first brake element 19, the latter can deflect upwards against the spring force exerted by the spring 18. In this way, the braking effect can be regulated much more easily than if the first brake element 19 were not movable in the axial direction.

[0101] The spring 18 is arranged in a rotationally fixed manner together with the first braking element 19, meaning that it does not rotate when the first pivot arm 2 rotates about the rotation axis D1. At its upper end, the spring 18 is supported against the pivot pin 12 via a sliding bushing 18.1, so that it cannot deflect upwards but is fixed in the axial direction. The sliding bushing 18.1 represents an axial plain bearing that decouples the spring 18 and the pivot pin 12 from each other, so that the pivot pin 12 can be rotated about the rotation axis D1 without affecting the spring 18.

[0102] As can be seen from the presentation of the Fig. 4 As can also be seen, the receptacle 1.1 is closed at the top by a cover 14 designed like a cap, so that as little dirt as possible can get into the gap between the rotating and the stationary elements. The cover 14 is connected to the pivot 12 via several screw connections. In the middle, however, the cover 14 has a recess in which the nut 17.1 is rotatably mounted in the axial direction, so that the nut 17.1 can be reached and turned, e.g. with a wrench, to adjust the braking effect of the braking device 15. The nut 17.1 therefore projects upwards relative to the pivot 12 and also relative to the cover 14. A seal 17.2 is also provided between the nut 17.1 and the cover 14, which prevents dirt and / or water from getting into the gap between the nut 17.1 and the cover 14 or the recess in the cover 14.

[0103] The representation of the Fig. 5 shows the second pivot bearing 10.2, which pivotally connects the first pivot arm 2 to the second pivot arm 3, in a sectional side view. Functionally, the pivot bearing 10.2 is essentially identical to the pivot bearing 10.1. This means that it also serves to pivotally connect two elements and also has a braking device 15, which functions like a friction brake and provides a braking effect that decelerates the pivoting movement. Furthermore, the braking effect can also be easily adjusted manually using an adjustment device 17. The following primarily describes the differences from the first pivot bearing 10.1.

[0104] The second pivot arm 3 is firmly connected to a pivot pin 12 via a screw connection. In contrast to the first pivot bearing, however, the pivot pin 12 is designed in two parts and comprises a first pivot pin part 12.2 and a second pivot pin part 12.3. This two-part design eliminates the need for a lock nut 13. This is because each pivot pin part 12.2, 12.3 has a shoulder 12.1, so that the inner ring of the pivot bearing 11 is secured or clamped axially between the two shoulders 12.1. The pivot bearing 11 is designed as a ball bearing with two rows of balls, and the outer ring of the pivot bearing 11 is supported axially on a shoulder 2.2 of the first pivot arm 2 in the receptacle 2.1 of the first pivot arm 2. The outer ring of the pivot bearing 11 is secured at the top by a retaining ring 13.1, so that the pivot bearing 11 is fixed accordingly in the first pivot arm 2 and enables a rotatable mounting of the pivot pin 12 and thus also of the second pivot arm 3 relative to the first pivot arm 2.

[0105] During assembly, the roller or pivot bearing 11 is first placed in the mount 2.1 of the first pivot arm 2 and then secured using the retaining ring 13.1. The first pivot pin part 12.2 is then inserted into the mount 2.1 from above, and the other pivot pin part 12.3 is inserted from below. The two pivot pin parts 12.2, 12.3 are then firmly connected to each other using the screw 12.4, so that both pivot pin parts 12.2, 12.3 can rotate together around the rotation axis D2 when the second pivot arm 3 pivots relative to the first pivot arm 2.

[0106] The braking device 15 of the second pivot bearing 10.2 essentially functions in a similar way to the braking device 15 of the first pivot bearing 10.2 described above. This is because two braking elements 19, 19.1 are also provided, with the first, upper braking element 19 being rotationally fixed relative to the first pivot arm 2, and the second, lower braking element 19.1 being rotationally fixed to the second pivot arm 3. When the two pivot arms 2, 3 pivot, a corresponding relative movement of the two braking elements 19, 19.1 rubbing against one another also occurs. Similar to the first pivot bearing 10.1, the first braking element 19 has radially projecting lugs that engage the first pivot arm 2 and rotationally couple the first pivot arm 2 and the first braking element 19 to one another.

[0107] The lower, second pivot pin part 12.3 has a thread into which the clamping bolt, designed in this embodiment as an adjusting screw 17.3, can be screwed from below with the nut. The shaft of the adjusting screw 17.3 thus forms the clamping bolt 16, and the head of the adjusting screw 17.3 forms the nut 17.1. The second braking element 19.1 is arranged in the receptacle 2.1 via the adjusting screw 17.3 and can be moved in the axial direction by rotating the adjusting screw 17.3. The second braking element 19.1 rests against the head of the screw. The essential difference between the two adjustment devices 17 of the two pivot bearings 10.1, 10.2 is that in the first pivot bearing 10.1 the clamping bolt 16 is only moved in the axial direction by turning the nut 17.1, whereas in the second pivot bearing 10.2 the clamping bolt 16 or the head of the adjustment screw 17.3 is also moved by turning the nut 17.1.the shaft of the adjusting screw 17.3 rotates.

[0108] Furthermore, in the second pivot bearing 10.2, a spring 18 designed as a disc spring is also provided above the first braking element 19, which allows an axial movement of the first braking element 19, so that the latter can deflect upwards when the second braking element 19.1 moves and is then pressed onto the second braking element 19.1 by the spring force acting on the first braking element 19.1 due to the tension of the spring 18, just as in the first pivot bearing 10.1. For the axial mounting of the spring 18, a sliding element in the form of a sliding bush 18.1 is again provided, via which the spring 18 can be supported in a rotationally decoupled manner in the axial direction relative to the pivot pin 12 which is rotationally coupled to the second pivot arm 3.

[0109] A significant difference to the first pivot bearing 10.1 is that in the second pivot bearing 10.2 the adjustment device 17 or the head of the adjusting screw 17.3 which has to be turned for adjustment is not accessible from above but from below, as can be seen from the illustration of the Fig. 3b is visible. To adjust the braking effect of the second pivot bearing 10.2, the operator of the carriage 100 or the weapon 101 must adjust the braking effect on the second pivot bearing 10.2 from below. This is accompanied by the fact that the adjustment device 17 of the first pivot bearing 10.1 is also better protected from dirt or falling rain by the third pivot bearing 10.3 or by the weapon mount 20, and that the second pivot bearing 10.2, in contrast, is in a significantly more exposed position, as can be seen from the illustration of the Fig. 3b can be seen.

[0110] The second pivot bearing 10.2 is also protected at the top by a cover 14 designed as a cap, which closes the top of the receptacle 2.1 of the second pivot arm 2. The cover 14 is connected to the pivot pin 12 or the upper pivot pin part 12.2 via several screws.

[0111] In order to fix the two swivel arms 2, 3 as well as the weapon holder 20 in the starting position, so that rotation about the rotation axes D1, D2, D3 is prevented, the Fig. 6 bis Fig. 8 The locking device 30 shown can be used, the structure and function of which is described below. The locking device 30 is arranged on the mounting element 1 and allows the elements to be fixed in place, which can be pivoted relative to the mounting element 1. The locking device 30 has a locking element 31 which is pivotally mounted about a locking axis K extending in the horizontal direction and which can be moved between the axis shown in the illustrations of the Fig. 6a und Fig. 6b Locking position A shown and the one shown in the illustrations of the Fig. 7a und Fig. 7b shown release position F. The locking axis K extends through the mounting element 1 or through the housing of the mounting element 1 laterally past the first pivot bearing 10.1.

[0112] In the locking position A, the locking element 31 extends essentially vertically and can contact the elements to be locked, i.e., the two pivot arms 2, 3 and the weapon mount 20, so that relative movement is no longer possible. In the release position F, the locking element 31 is in a lying position extending horizontally. The pivot arms 2, 3 and the weapon mount 20 can thus be pivoted over the locking element 31 and can be pivoted largely freely by 360 degrees about the respective rotation axes D1, D2, D3.

[0113] In order to pivot the locking element 31 up and down accordingly, it is arranged on a bolt 34, which is mounted in the mounting element 1 via a pivot bearing for rotation about the locking axis K. To move the locking element 31 accordingly, a handle 33 is provided, which is rotationally coupled to the bolt 34 and thus also to the locking element 31. The locking element 31 can thus be moved back and forth about the locking axis K between the locking position A and the release position F via the handle 33.

[0114] In order to lock the two swivel arms 2, 3 and the weapon holder 20, these each have locking contours 2.5, 3.5, 20.5 projecting laterally in the axial direction, which are shown in the illustrations of the Fig. 7a und Fig. 7b can be seen. In the initial or zero position, these locking contours 2.5, 3.5, 20.5 lie one above the other, so that they can be contacted simultaneously by the locking element 31. The locking contours 2.5, 3.5, 20.5 can engage with the locking element 31, creating a positive connection between the locking element 31 and the two pivot arms 2, 3 as well as the weapon mount 20, which reliably prevents movement of the elements.

[0115] To realize the positive connection, the locking element 31 also has a locking contour 35, which is designed to correspond to the locking contours 2.5, 3.5, 20.5 of the pivotable elements 2, 3, 20. The locking contour 35 is accordingly designed as a recess or as a slot-shaped receptacle into which the projecting locking contours 2.5, 3.5, 20.5 can engage in a positive fit.

[0116] To ensure that the locking contours 35, 2.5, 3.5, 20.5 interact and engage with each other, the locking element 31 can not only be rotated or pivoted about the locking axis K, but can also be moved linearly in the direction of the locking axis K between a locking and unlocking position. For this purpose, the lever 34 can be pulled accordingly, or a force acting in the direction of the locking axis K can be applied.

[0117] As can be seen from the illustrations of the Fig. 6a or Fig. 7a As can be seen, a spring 32 is arranged on the bolt 34, which preloads the locking element 31 in a linear direction. This spring 32 thus ensures that the locking element 31 is automatically transferred to the locking position when the handle 33 is released, in which the locking contours 2.5, 3.5, 20.5 can engage with the locking contour 35 of the locking element 31. The locking function thus created ensures reliable locking or lashing, and when the locking contours 2.5, 3.5, 20.5, 35 are locked together, no further relative movement is possible.

[0118] In order to move the pivot arms 2, 3 or the weapon mount 20 again, the locking contours 2.5, 3.5, 20.5, 35 must first be disengaged so that the locking element 31 can be pivoted back into the release position F. To do so, the locking element 31 must be moved via the handle 33 in a linear direction and against the force of the spring 32 into a release position, so that the locking contour 35 is essentially pulled away from the other locking contours 2.5, 3.5, 20.5. Only then, in this release position, can the locking element 31 be pivoted back downward into the release position F.

[0119] In order to prevent the locking element 31 from being moved inadvertently in the release position F, when it is not in use, it can be fixed in the release position F at the position shown in the illustration of the Fig. 6b The locking contour 1.5 shown can be locked. The locking contour 1.5 is arranged on the outside of the mounting element 1 and is designed as a fixed and laterally projecting locking pin. Analogous to the connection or interaction of the locking contour 35 with the locking contours 2.5, 3.5, 20.5 of the pivot arms 2, 3 and the weapon mount 20 in the locking position A, the locking contour 1.5 of the mounting element 1 can engage in the locking contour 35 of the locking element 31 in the release position F or can engage due to the spring preload of the locking element 31 and thus connect the locking element 31 to the mounting element 1 in a form-fitting and immovable manner.

[0120] To release the locking element 31 from the release position F back into the locking position A, the positive connection between the locking contour 35 and the locking contour 1.5 must first be released. To do so, the locking element 31 can be pulled off the locking contour 1.5 using the handle 33 against the force of the spring 32 and moved into the unlocking position. In this position, the locking element 31 can then be rotated again about the locking axis K.

[0121] Since in the locking position A no movement of the swivel arms 2, 3 and the weapon mount 20 is possible, the locking contours 2.5, 3.5, 20.5 must be accommodated in the locking contour 35 of the locking element 31 with as little play as possible. However, this requires very precise positioning of the swivel arms 2, 3 and the weapon mount 20, so that the respective locking contours 2.5, 3.5, 20.5 are aligned as precisely as possible. In order to align the swivel arms 2, 3 and the weapon mount 20 accordingly, the locking element 31 has a stop area 36, ​​which in the illustration of the Fig. 8 can be seen. When the locking element 31 is moved into the locking position A, the locking contours 2.5, 3.5, 20.5 can run against the stop area 36, ​​thus aligning themselves in line and then, with a corresponding movement of the locking element 31 in the direction of the locking axis K, plunge together into the locking contour 35 of the locking element 31. In order to align the locking contours 2.5, 3.5, 20.5 accordingly, the pivot arms 2, 3 and the weapon mount 20 can also be moved, in particular the hand, such that the corresponding locking contours 2.5, 3.5, 20.5 run against the stop area 36 and thus align themselves.

[0122] In order to achieve not only an azimuth lashing via the locking device 30 but also an elevation lashing, so that the weapon 101 can no longer be moved in the elevation direction, a corresponding elevation lock 23 is provided, the structure of which is shown in the illustrations in the Fig. 9a und Fig. 9b The elevation lock 23 essentially consists of a lever 23.1 which is pivotally mounted on the weapon mount 22 and a locking point 23.2 which is arranged on the elevation bearing 21 or on a cheek 21.1 of the elevation bearing 21. The lever 23.1 is rotatably mounted about an axis extending parallel to the elevation axis E and in the Fig. 9a The weapon mount 22, together with the weapon 101 accommodated therein, is thus pivotable relative to the elevation bearing 21 about the elevation axis E.

[0123] In order to prevent such movement about the elevation axis E, so that the weapon 101 is fixed in this respect, the lever 23.1 can now be pivoted and connected to the locking point 23.2. The locking point 23.2 is designed as a bore and functions as a receiving bushing with which the lever 23.1 can lock via the handle 23.3. The handle 23.3 is arranged at the end of the lever 23.1 opposite the pivot axis and is mounted so as to be movable parallel to the pivot axis. The handle 23.3 can be moved against the force of a spring and, when released, springs back to its original position driven by the spring. In order to lock the weapon mount 22, the handle 23.3 is first moved against the force of the spring using a tensile force and then pivoted until it is aligned with the locking point 23.2. If the handle 23.3 is released, it or a lever not shown in the illustrations and connected to the handle 23.3, the bolt connected to the weapon mount 22 engages the locking point 23.2 due to the preload of the spring, so that pivoting movement about the elevation axis E is no longer possible. In order to pivot the weapon mount 22 again, the corresponding elevation lock must first be released, for which purpose the handle 23.3 is moved against the force of the spring and the bolt is thus pulled out of the locking point 23.2.

[0124] The representation of the Fig. 10 now shows the weapon mount 22 and the weapon 101 in an exploded view. The weapon mount 22 has two vertically extending retaining cheeks 22.1, 22.2, between which the weapon 101 is held with virtually no play, so that the weapon 101 cannot slip or deflect to the left or right in the weapon mount 22. In order to fix the weapon 101 in the weapon mount 22, according to the illustration of the Fig. 10 two weapon fixations 24 are provided, which detachably connect the weapon to the weapon mount 22 in the front and rear areas.

[0125] For this purpose, the weapon 101 is equipped with holding recesses 101.1, 101.2 extending transversely through the weapon. The two parallel holding cheeks 22.1, 22.2 each have two recesses 22.3, with the recesses 22.3 of the two holding cheeks 22.1, 22.2 facing each other in pairs. The fixing bolt 25 of the weapon fixation 24 can thus be inserted from the side through the recess 22.3 of a holding cheek 22.1, 22.2 and can also extend through one of the holding recesses 101.1, 101.2 of the weapon 101 into the recess 22.3 of the opposite cheek 22.1, 22.2. The weapon 101 is then secured in the weapon mount 22 via the fixing bolt 25 and can no longer be moved relative to the weapon mount 22.

[0126] In the illustrated embodiment, the two front and opposing recesses 22.3 are designed as elongated holes, so that they are larger than the diameter of the fixing bolt 25. This design allows for compensation of manufacturing tolerances, and the holding recesses 101.1, 101.2 can vary within certain limits. Furthermore, for example, during continuous fire, heating and thus expansion of the weapon 101 can occur, which can be compensated for by the corresponding freedom of movement of the fixing bolt 25 in the front recesses 22.3. However, the rear recesses 22.3 are adapted to the size or cross-section of the fixing bolt 25, so that no absolute movement of the weapon 101 is possible, but only a small relative movement of the two holding recesses 101.1, 101.2.

[0127] The design of the weapon fixation 24 should now be examined with regard to the different positions in the Fig. 11a bis Fig. 11c and the detailed views of the Fig. 12a und Fig. 12b be explained in more detail. The presentation of the Fig. 11a shows a fixing bolt 25 partially inserted into the recess 22.3 and into the holding recess 101.1 of the weapon 101. This is connected in one end region to a substantially ring-shaped handle 29, via which the fixing bolt 25 can be inserted both in the axial direction into the recess 22.3 and can be rotated back and forth about its longitudinal axis for locking.

[0128] A locking mechanism 26 is provided to ensure that the fixing bolt 25 is fixed in the inserted position securing the weapon 101 in the weapon mount 22, and cannot be inadvertently moved in the axial direction. The locking mechanism 26 essentially consists of a first locking element 27, which is arranged in the region of the handle 29 and is thus movable together with the fixing bolt 25, and a second locking element 28, which is arranged on the outside of the retaining cheek 22.1. The locking element 28 has a recess which geometrically corresponds to the recess 22.3 of the retaining cheek 22.1. As can be seen from the illustration of the Fig. 10 As can be seen, the recess of the locking element 28 arranged in the front area of ​​the weapon holder 22 has the shape of an elongated hole and the recess of the locking element 28 arranged in the rear area of ​​the weapon holder 22 has a circular recess.

[0129] Furthermore, the locking element 28 has a plate-shaped base element 28.2, which is connected to projections 28.3 which are opposite one another with respect to the recess and are arranged substantially spaced apart and parallel to the base element 28.2. According to the illustration of the Fig. 10 The left projection 28.3, as viewed from the fixing bolt 25, points downwards, and the right projection 28.3, as viewed from the fixing bolt 25, points upwards. The distance between the projections 28.3 and the base element 28.2 creates a rear grip 28.1 on each side of the recess, into which the first locking element 27 can engage to positively lock the fixing bolt 25 so that it is fixed in the axial direction. For this purpose, the first locking element 27 has two locking projections 27.1 that project radially with respect to the longitudinal axis of the fixing bolt 25 and can be moved in the same direction into the rear grips 28.1 by rotating the fixing bolt 25.

[0130] In the representations of the Fig. 11c und Fig. 11d The fixing bolt 25 has been rotated approximately 90 degrees clockwise around its longitudinal axis, so that the two locking projections 27.1 engage with the rear grips 28.1 and are positioned in the end region of the rear grips 28.1. Further clockwise rotation is then no longer possible. In order to move the fixing bolt 25 in the axial direction and thus withdraw it from the recess 22.3, the lock must first be released. To do this, the fixing bolt 25 or the two locking projections 27.1 must be rotated back counterclockwise so that they no longer engage behind the projections 28.3 and are therefore no longer positioned in the rear grips 28.1.

[0131] Furthermore, the locking mechanism 27 comprises a safety feature which prevents the fixing bolt 25 from being simply turned back counterclockwise. In order to release the locking mechanism, a pressure force must first be applied in the insertion direction via the handle 29 until the handle 29 and thus also the first locking element 27 can be turned into the unlocking position. To achieve this, the projections 28.3 have an angled portion 28.4 at their ends which extends in the direction of the base element 28.2 and which narrows the rear grip 28.1 in this area. In order for the locking projection 27.1 arranged in the rear grip 28.1 and behind the angled portion 28.4 to be able to move out of the position shown in the illustration of the Fig. 11d To be able to rotate the locking element back to the position shown, it must first be moved slightly toward the base element 28.2. This means that the angled portion 28.4 no longer engages behind the locking projection 27.1, and the locking element 27 can be rotated back to release the fixing bolt 25.

[0132] In order to hold the first locking projections 27.1 in the rotation-locked position behind the angled portions 28.4, a spring-loaded pressure plate 25.1 is provided, which is shown in the illustrations of the Fig. 12a und Fig. 12b can be seen. The pressure plate 25.1 is annular and mounted on the fixing bolt 25 for linear movement. The pressure plate 25.1 is connected to the handle 29 or to the first locking element 27 via a spring 27.2. The first locking element 27 has a cup-shaped design so that it supports the spring 27.2 in the radial direction and basically functions as a type of axial guide for the spring 27.2 and for the pressure plate 25.1. In the illustrations of the Fig. 11a bis 11 The spring 27.2 is therefore not visible, but is covered by the locking element 27.

[0133] For locking, the fixing bolt 25 can now first be inserted into the recess 22.3 until the pressure plate 25.1 rests against the retaining cheek 22.1 or the base element 28.2 of the second locking element 28. In this position, however, the fixing bolt 25 cannot yet be rotated about its longitudinal axis into the locking position, since the locking projections 27.1 strike the angled portion 28.4 upon a corresponding movement, thus preventing movement into the rear grip 28.1. To move the locking projections 27.1 into the rear grip 28.1, they must first be moved further in the direction of the retaining cheek 22.1 or the base element 28.2 of the second locking element 28 until they rest against the base element 28.2. In this position, the spring 27.2 is compressed and the pressure plate 25.1 lies in a plane with the locking projections 27.1, as can be seen from the illustration of the Fig. 12b is visible. When the fixing bolt 25 is rotated in this position, the two locking projections 27.1 are guided past the respective angled portions 28.4.

[0134] When the locking projections 27.1 have reached their final position locking the two locking elements 27, 28 together, the handle 29 can be released. The tensioned spring 27.2 moves the locking projections 27.1 axially away from the base element 28.2 of the second locking element 28, so that they are then arranged behind the angled portion 28.4. A return rotation of the handle 29 into the unlocked position is then prevented by the angled portions 28, as can also be seen from the illustration of the Fig. 11d can be seen. Bezugszeichen:
