Abstract
Description
[0001] The present invention relates to a gas-operated rifle, in particular a sporting gas-operated rifle for sporting use, with at least one ball joint for stress-free connection of the barrel of the gas-operated rifle to the rifle stock.
[0002] German patent application DE 23 29 425 A1 discloses a gas-operated rifle in which the barrel is arranged in a sleeve that is attached to the rifle stock by two screw connections: a bearing block is attached to the rear end of the rifle sleeve, the base of which rests on the stock and is held in place by a screw. The barrel end of the rifle sleeve is held in firm contact with the stock by a screw that is screwed into a threaded insert that is fixedly connected to the rifle sleeve.
[0003] One disadvantage of this well-known gas-operated rifle is that twisting and / or tensioning of the barrel can occur during the attachment of the barrel to the stock, which negatively affects accuracy.
[0004] The present invention is therefore based on the objective of creating a gas-operated rifle in which the barrel is attached to the stock with as little tension as possible, in order to increase accuracy.
[0005] This problem is solved according to the present invention by a gas-operated rifle, in particular a sporting gas-operated rifle, with the features of claim 1. Particularly advantageous embodiments are set forth in the dependent claims.
[0006] The gas-operated rifle according to the invention, in particular a sporting gas-operated rifle, comprises an elongated stock extending along a longitudinal axis and having a first end for placing the rifle against a part of the shooter's body and a second end opposite the first end. An air pressure system is provided on the stock, supplying compressed propellant gas for accelerating a projectile. The gas-operated rifle further comprises a barrel attached to the air pressure system and a barrel bearing for mounting the barrel to the stock. A fastening device with a screw connection serves to attach the barrel bearing to the barrel and the stock. The gas-operated rifle further comprises a ball joint with a ball head and a socket for receiving the ball head, the ball joint connecting the barrel and the stock in a pivotable manner relative to each other.Preferably, the gas-operated rifle may also have more than one ball joint, for example two ball joints, for pivoting the connection between the barrel and stock relative to each other.
[0007] The inclusion of a ball joint advantageously compensates for rotations and / or stresses of the barrel relative to the stock that occur during the fastening, i.e., screwing, of the barrel bearing or the barrel to the stock. These rotations and / or stresses are compensated for by pivoting the barrel, particularly the barrel bearing with the barrel, and the rifle stock relative to each other. This allows for a barrel bearing with significantly reduced stress, ideally a stress-free bearing, thereby advantageously increasing the accuracy of the gas-operated rifle.
[0008] The compressed air system used in gas-operated rifles can comprise various known systems, which are therefore not described in detail here. For example, the compressed air system may include a spring-loaded piston to generate the propellant air for the projectile. Alternatively, the compressed air system may include a pressurized gas reservoir, a valve, etc., to provide compressed propellant gas for accelerating a projectile.
[0009] The barrel bearing is an elongated component that, in its uninstalled state, forms a separate part of the gas-operated rifle from the stock. The stock and the barrel bearing are connected by a fastening device or screw connection. The barrel bearing has a central axis that extends in the same direction and / or, in particular, approximately parallel to the longitudinal axis of the stock when the barrel bearing is attached to the stock. The barrel bearing has at least one (first) sleeve-shaped recess in which the barrel can be received and / or stored. The sleeve-shaped recess is preferably cylindrical on its inner surface to encompass a section of the rifle barrel. These features advantageously and reliably support the barrel and connect it to the stock.
[0010] Preferably, the barrel mount is additionally designed to accommodate and / or store a pressurized gas reservoir, for example, a gas cartridge, of the gas-operated rifle. Preferably, the barrel mount is designed to also attach the pressurized gas reservoir to the stock using the fastening device or screw connection. Thus, the barrel and the pressurized gas reservoir are advantageously positioned and secured to the stock by a single component, namely the barrel mount. Preferably, the barrel mount is designed such that the pressurized gas reservoir is arranged between the barrel and the rifle stock when the barrel mount is attached to the rifle stock. The barrel mount has at least a second sleeve-shaped receptacle in which the pressurized gas reservoir can be received and / or stored. The second sleeve-shaped receptacle is preferably cylindrical on its inner surface to encompass a section of the pressurized gas reservoir.These features ensure that the pressurised gas reservoir is reliably mounted and connected to the rifle stock in an advantageous manner.
[0011] The barrel bearing is preferably made of plastic. The barrel bearing is preferably designed as a clamping device or has one or more clamping devices so that the rifle barrel and, if applicable, the compressed gas reservoir can be clamped in the barrel bearing. Preferably, the clamping device(s) are provided with screws and / or spring-loaded clamping arms to reliably clamp the rifle barrel and, if applicable, the compressed gas reservoir in the barrel bearing. These features advantageously ensure that the barrel and, if applicable, the compressed gas reservoir are reliably held in the barrel bearing and attached to and / or positioned on the stock.
[0012] Preferably, at least a part of the ball joint, in particular the ball head, is designed as part of the mounting device. In particular, at least a part of the ball joint, in particular the ball head, is connected to the mounting device in such a way that this part of the ball joint and the mounting device can move together when the barrel and stock are pivoted relative to each other. This advantageously enables a particularly compact integration of the ball joint into the gas-operated rifle.
[0013] Preferably, the ball joint, or in particular at least a part thereof, is arranged on the stock and / or on the barrel bearing. More preferably, the ball joint, or in particular at least a part thereof, is arranged between the stock and the barrel bearing. These features advantageously enable particularly precise or fine pivoting of the barrel and the stock relative to each other.
[0014] Preferably, the ball joint is formed by a spherical disc or a spherical segment. Preferably, the ball joint comprises a flat surface and a convex surface opposite the flat surface, the convex surface being supported and / or received in the ball joint socket. Preferably, the ball joint is made of metal, for example, steel. Preferably, the convex surface of the ball joint or spherical segment comprises a spherical cap and / or a spherical cap-shaped form. Preferably, the largest diameter of the spherical segment is considerably larger than the largest height of the spherical segment; for example, the ratio is at least 2:1, preferably at least 3:1 or more than 3:1. These features allow for space-saving integration of the ball joint into the gas-operated rifle.
[0015] The ball joint is optionally a separate element, in particular a separate ball segment, or part of the fastening device, for example a threaded element of the fastening device or screw connection, as described above. For example, the ball joint is formed integrally with the threaded element, in particular with a threaded element rotatable relative to the barrel bearing and / or the stock, thereby advantageously achieving a space-saving integration of the ball joint into the gas-operated rifle.
[0016] Preferably, the rod end has a bore through which at least part of the screw connection extends. Preferably, the bore extends through the ball disc or ball segment between the flat surface and the convex surface. Preferably, the convex surface or ball cap and / or the flat surface surrounds the bore in an annular fashion. Preferably, the bore is located centrally in the rod end, particularly in the ball disc, so that the annular, convex, and / or flat surface uniformly surrounds the bore over the entire circumference of the ball disc or ball segment. These features enable particularly smooth and consistent actuation of the barrel bearing, i.e., the pivoting of the barrel bearing and the barrel relative to the stock.
[0017] Preferably, the spherical disc surrounds one or more threaded elements of the fastening device. Preferably, the inner wall of the spherical disc's bore contacts at least part of the screw connection, for example, a threaded element. This advantageously results in an extremely compact arrangement of the spherical disc as part of the screw connection.
[0018] Preferably, the bearing housing has a recess in which at least a portion of the rod end, in particular the ball disc, is received and / or supported. The recess is preferably formed as a projection in a wall of the bearing housing, particularly in the wall of the bearing housing facing the inside of the shaft on which the ball socket is provided. The recess is preferably circular. Preferably, the flat surface of the rod end or ball disc is received in the recess. Preferably, the convex surface or spherical cap of the rod end projects from the recess, in particular into an air gap between the bearing housing and the shaft, so that the convex surface or spherical cap can be received in the ball socket. These features advantageously and reliably connect the rod end to the bearing housing, thus preventing relative movement between the bearing housing and the rod end.
[0019] Preferably, the ball joint socket is formed as part of the stock. Preferably, the ball joint socket is formed or provided within a stock body, in particular such that the ball joint head, especially the convex surface, is mounted on the stock. Preferably, the ball joint socket is provided or formed on an inner side of the stock, in particular on a side of the stock that faces the barrel bearing and / or is closer than an outer side of the stock. Preferably, the stock, in particular its inner side, and the barrel bearing are spaced apart from each other and / or separated from each other by an air gap. Preferably, the ball joint head or the ball disc is arranged at least partially within the air gap. These features allow the barrel, in particular the barrel bearing with the barrel, and the stock to pivot freely relative to each other.
[0020] Alternatively, the ball joint socket is provided in a bearing disc. Preferably, the bearing disc is a separate component of the gas-operated rifle. Preferably, the bearing disc, when installed, forms part of the mounting device. Preferably, a bore extends through the bearing disc, in which at least part of the mounting device or screw connection, for example, a threaded element, can be received or accommodated. These features advantageously facilitate the manufacture of the ball joint socket and its assembly in the gas-operated rifle.
[0021] Preferably, the ball joint socket has a concave surface in or on which the ball head, in particular its convex or spherical surface, is arranged. Preferably, the concave and convex surfaces contact each other. Preferably, the concave and convex surfaces are complementary to each other and / or have complementary angles of curvature. These features advantageously result in smooth movement of the ball disc relative to the ball joint socket and thus of the bearing and the barrel relative to the shaft.
[0022] Preferably, the shank includes a bore through which at least a portion of the screw connection extends. Preferably, the bore extends through a shank wall or body. In particular, the bore penetrates the shank wall opposite the wall of the barrel bearing with the receptacle for the ball washer when the barrel bearing is attached to the shank. Preferably, the ball socket is provided at the bore penetrating the shank. In particular, the bore is designed such that at least a portion of the screw connection, for example, a threaded element of the screw connection, extends into and / or through the shank and the ball socket. These features make the screw connection easily accessible, so that the barrel bearing and / or the barrel and, if applicable, the compressed gas reservoir can be advantageously and easily screwed to the shank.
[0023] In particular, the bore is designed such that at least part of the convex surface of the ball disc projects into the bore and / or the convex surface of the ball disc is supported on one or more edges bounding the bore, thereby resulting in a particularly smooth pivoting of the ball disc in the socket.
[0024] Preferably, the bore of the shank comprises or forms a longitudinal slot extending along the longitudinal axis of the shank, particularly in a shank wall or the shank body, wherein at least a part of the fastening device is slidably received in the longitudinal slot, such that the fastening device, in particular the screw connection, preferably a part of the ball joint, for example the ball head, and the barrel bearing are slidably displaceable along the longitudinal axis of the shank relative to the barrel and / or shank. Preferably, at least a part of the fastening device and / or the screw connection, in particular a threaded part, and / or a part of the ball head is guided in and / or on the longitudinal slot.In particular, the longitudinal slot is designed such that at least a portion of the convex surface of the ball bearing projects into the longitudinal slot and / or the convex surface of the ball bearing is supported on one or more edges bounding the longitudinal slot. These features, especially the adjustability of the barrel bearing relative to the barrel and stock, advantageously allow the barrel bearing to be attached at a multitude of positions relative to the stock, thereby further reducing barrel stress caused by tightening the barrel bearing to the stock. The adjustment is advantageously particularly smooth due to the at least partial arrangement of the convex surface within the longitudinal slot and / or on its edges.
[0025] The shaft preferably comprises several sockets arranged linearly along the longitudinal axis of the shaft, and which are preferably designed as longitudinal slots. Preferably, the several sockets are separated from one another by webs of the shaft or a shaft wall. Preferably, the fastening device can be arranged in or on at least two of the sockets, particularly as described above, thereby advantageously increasing the number of positions at which the bearing can be fastened relative to the shaft.
[0026] Preferably, the wall thickness of at least one wall of the rifle stock in which the ball joint socket is provided, or of the bearing disc, decreases towards the center point of the ball joint socket to form the (concave) ball joint socket. In particular, the wall thickness of at least one wall of the rifle stock in which the ball joint socket is provided decreases towards the bore through the ball joint socket to form the (concave) ball joint socket. In particular, the wall thickness of one or more side walls surrounding the longitudinal slot of the ball joint socket decreases towards the longitudinal slot to form the concave ball joint socket with the longitudinal slot.In particular, according to these embodiments, the height of at least one shaft wall and / or the wall thickness of at least one shaft wall, in which the socket joint, especially the longitudinal slot, is provided, decreases in the direction of the center point, the bore, or the longitudinal slot. Specifically, the one or more shaft walls taper in the direction of the center point, the bore, or the longitudinal slot. These features advantageously form the socket joint integrally with the shaft.
[0027] Preferably, the screw connection of the fastening device has a threaded element that is not rotatable relative to the barrel bearing and / or the stock. Preferably, the screw connection of the fastening device has a threaded element that is rotatable relative to the barrel bearing and / or the stock, which can be screwed to the non-rotatable threaded element in order to fasten the barrel bearing to the barrel and, if applicable, the compressed gas reservoir to the rifle stock.
[0028] Preferably, the non-rotatable threaded element is countersunk in a wall of the bearing, particularly in the wall facing the shaft and / or in which the receptacle for at least a portion of the ball disc is provided. Preferably, a bore is provided in the bearing wall in which the non-rotatable threaded element is countersunk or received. Preferably, the bore opens, particularly centrally, into the bearing receptacle for the ball disc. Preferably, the non-rotatable threaded element comprises, at least in one section, a polygonal outer wall, for example, a four- or six-sided shaft or head, and the bearing bore comprises a complementary polygonal inner wall, so that the non-rotatable threaded element can be received in the bore in a rotationally fixed manner when the two polygonal walls are joined.Of course, other non-rotatable countersinking methods for the non-rotating threaded element in a bearing wall are also possible, for example, by injection molding if the bearing is manufactured using an injection molding process. These features guarantee a reliable connection of the screw connection, especially of the non-rotating threaded element, to the bearing.
[0029] The non-rotatable threaded element is preferably designed as a hollow screw with an internal thread. The rotatable threaded element is preferably designed as a screw with an external thread that can be connected to the internal thread of the non-rotatable threaded element. The rotatable threaded element and / or the non-rotatable threaded element preferably extend through the bore in the wall of the barrel bearing. At least a section of the hollow screw and / or the screw with an external thread preferably extends through the bore of the ball joint or the ball disc. When the rotatable and the non-rotatable threaded elements are screwed together, they form, together with the ball joint through which they extend and the barrel bearing, a compact unit that, together with the barrel and, if applicable, the compressed gas reservoir, can be pivoted and / or displaced relative to the stock.This compact unit advantageously facilitates the swiveling or sliding process.
[0030] Preferably, the threaded element, which is rotatable relative to the bearing, includes at least a portion of the ball joint, for example, the convexly shaped ball head. This portion of the ball joint is particularly integral with the threaded element. This portion, for example, the ball head, is preferably received in a complementarily shaped, convex socket of the bearing disk. However, the arrangement of the ball head and the socket on the other component is also possible. The ball head and the socket, particularly their convex surfaces, are designed such that, during tightening of the screw connection, the rotatable threaded element with the ball head can pivot relative to the bearing disk with the ball head.These features, in particular the one-piece design of the rotatable threaded element and at least part of the ball joint, advantageously allow for space-saving integration of the ball joint into the gas-operated rifle. Preferably, the bearing disc is also part of the mounting device or connected to it and thus displaceable relative to the barrel and / or stock, as described above.
[0031] The gas-operated rifle particularly preferably features a first ball joint and a second ball joint for pivoting the barrel and stock relative to each other, the first and second ball joints being located on opposite sides of the bore, in particular the longitudinal slot, that passes through the stock. The first and second ball bearings, in particular, form a bearing and a counter-bearing, which advantageously enable a particularly reliable and precise pivoting of the barrel and stock relative to each other and stabilize the attachment and / or (pivoted) position of the barrel bearing on the stock.
[0032] Preferably, the first and second ball joints are arranged on opposite sides of the shaft, particularly at the bore or longitudinal slot in the shaft. Preferably, at least parts of the first and second ball joints are arranged on the bore of the shaft, particularly on edges defining and / or limiting the bore, and / or contact it. This spatially close arrangement of the first and second ball joints on the shaft advantageously provides the fastening device with additional stability.
[0033] As mentioned above, the barrel bearing preferably also supports a pressurized gas reservoir, for example a gas cartridge, of the gas-operated rifle. Such pressurized gas reservoirs are elongated, metallic containers known to those skilled in the art. Preferably, rings are provided in the barrel bearing and / or around the pressurized gas reservoir, which surround the gas reservoir and are designed to allow the gas reservoir to be easily inserted into or removed from the barrel bearing by sliding. The rings are preferably made of plastic.
[0034] Preferably, the air pressure system is further attached to the barrel at the first end of the stock, in particular by screws. The barrel is thus preferably attached to the stock at exactly two points, and no more than two. Such a two-point mounting advantageously reduces stress on the barrel and optimally enables an almost stress-free mounting of the barrel on the stock.
[0035] The invention is explained below with reference to preferred embodiments and the accompanying drawings. It shows the

[0039] Figure 4 a sectional view of the shaft, the bearing and the ball joints along the AA axis of the Figure 3 .
[0040] The one in Figure 1The depicted gas-operated rifle 1, in particular a sporting gas-operated rifle, comprises an elongated stock 2 extending along a longitudinal axis 3 and having a first end 4 for placing the gas-operated rifle 1 against a part of the shooter's body and a second end 5, which is arranged opposite the first end 4. An air pressure system 24 is provided on the stock 2, which supplies compressed propellant gas for accelerating a projectile. A barrel 6 extends from the air pressure system 24 along the longitudinal axis 3 of the stock towards the second end 5 and beyond. A compressed gas reservoir 23, for example a compressed gas cartridge, is pneumatically connected to the air pressure system 24 and supplies the air pressure system 24 with propellant gas.
[0041] The gas-operated rifle 1 further includes a barrel bearing 7 for mounting the barrel 6 on the stock 2, see in particular Figures 2 and 3The plastic barrel bearing 7 has a first receptacle 35 for the barrel 6 and a second receptacle 36 for the compressed gas reservoir 23. The receptacles 35 and 36 are arranged one above the other, such that the receptacle 36, or the compressed gas cartridge 23 stored therein, is closer to the stock 2 than the receptacle 35, or the barrel 6 housed therein. The receptacles 35 and 36 are sleeve- or tube-shaped, and in particular, they have sleeve- or tube-shaped sections that enclose the barrel 6 and the compressed gas reservoir 23, respectively. At least one clamping section 37 is arranged between the receptacles 35 and 36, which also connects them. The clamping section 37 has opposing jaws 38 that are movable relative to each other and are separated from each other by a slot 39. The slot 39 extends essentially parallel to the shaft longitudinal axis 3 and / or a longitudinal axis 40 of the bearing 7.The opposing jaws 38 are screwed together via a screw connection 41, which, for example, has threads and threaded screws 42 arranged in the jaws 38. This reduces the clear width of the slot 39 and reliably clamps the barrel 6 and the compressed gas reservoir 23 in the barrel bearing 7. Two rings 43, which surround the compressed gas reservoir 23, can be received in the barrel bearing 7 and are designed to allow the compressed gas reservoir 23 to be easily inserted into or removed from the barrel bearing 7 by sliding motion.
[0042] A fastening device 8 is provided for attaching the barrel bearing 7, and thus the barrel 6 and the compressed gas reservoir 23, to the shaft 2. The fastening device 8 comprises a screw connection 9 with a threaded element 33 rotatable relative to the barrel bearing 7 and a threaded element 34 not rotatable relative to the barrel bearing 7. The non-rotatable threaded element 34 is designed as a hollow screw with an internal thread. The rotatable threaded element 33 is designed as a screw with an external thread, which can be screwed into the internal thread of the non-rotatable threaded element 34. The rotatable threaded element 33 and the non-rotatable threaded element 34 extend through a bore 44 in the barrel bearing 7 and through a bore 21 passing through the shaft 2. The non-rotatable threaded element 34 is countersunk in a wall of the barrel bearing 7, in particular in the bore 44. The non-rotatable threaded element 33 and the non-rotatable threaded element 34 areThe hollow screw 34 comprises a polygonal outer wall, in particular a polygonal head 34A (see . Figure 2 ), and the bore 44 of the bearing 7 comprises at least one section a complementary, polygonal inner wall, so that the non-rotatable threaded element 34 can be received in the bore 44 in a rotationally fixed manner when the two polygonal walls are joined together (see Figure 3 ).
[0043] To attach the barrel 6 to the stock 2 with as little stress as possible, a ball joint system is provided on the compressed gas rifle 1, in particular on the stock 2, comprising two ball joints 10, 30. A first ball joint 10 with a ball head 11 and a socket 12 for receiving the ball head 11 is provided on the barrel bearing 7 and on a body 20 or a wall of the stock 2. A second ball joint 30 with a ball head 31 and a socket 32 for receiving the ball head 31 is arranged opposite the first ball joint 10, on the stock body 20. The two ball joints 10, 30 are provided, in particular, on opposite sides of the bore 21 that passes through the stock 2.
[0044] The respective joint head 11, 31 of the ball joints 10, 30 is formed by a spherical disk or a spherical segment 11A. The spherical segment 11A of the first ball joint 10 is an independent component, while the spherical segment of the second ball joint 30 is formed as part of the rotatable threaded element 33. In particular, the joint head 31 is an integral and / or integral part of the rotatable threaded element 33; for example, the joint head 31 is formed as part of a screw head of the threaded element 33, which is designed as a screw.
[0045] The joint heads 11, 31 each have a flat surface 15 and a convex surface 16 arranged opposite the flat surface 15, the convex surfaces 16 being mounted in the respective joint sockets 12, 32. The concave joint sockets 12, 32 and the convex surfaces or caps 16 have essentially complementary radii of curvature, so that the joint heads 11, 31 and associated components of the gas-operated rifle, in particular the barrel 6 and the barrel bearing 7, are pivotable in the joint sockets 12, 32 relative to the stock 2.
[0046] As can be seen in particular from the Figure 2As can be seen, the rod end 11, 11A of the first ball joint 10 has a bore 14 through which at least part of the screw connection 9 extends. The flat surface 15 and the convex surface or spherical cap 16 surround the bore 14 in an annular manner. In the assembled state, both the rotatable threaded element 33 and the non-rotatable threaded element 34 extend through the bore 14 and / or the rod end 11, see Figure 3 .
[0047] The bearing 7 has a receptacle 17 in which at least a part of the ball joint 11, in particular the flat surface 15, is received and / or supported. The receptacle 17 is designed as a recess in a wall or body of the bearing 7. The convex surface or spherical cap 16 of the ball joint 11 projects from the receptacle 17 into an air gap 45 between the bearing 7 and the shaft 2, so that the convex surface or spherical cap 16 can be received in the socket 12.
[0048] The socket 12 of the first ball joint 10 is formed in the shaft body 20 of the shaft 2, in particular on a side of the shaft body 20 facing the bearing 7. The ball head 11 is arranged in the air gap 45 between the shaft body 20 and the bearing 7. To form the socket 12 in the shaft body 20, the wall thickness of at least one wall 18 of the shaft 2 or shaft body 20 decreases towards a center point of the socket 12, see Figure 1. Figures 3 and 4 .
[0049] The socket 32 of the second ball joint 30 is provided in a bearing disc 19. The bearing disc 19 is a separate component of the gas-operated rifle 1. A bore 46 extends through the bearing disc 19, in which at least part of the fastening device 8 or screw connection 9, in particular at least one of the threaded elements 33, 34, is received. The wall thickness of the bearing disc 19 decreases towards the center point of the socket 32 to form the concavely shaped socket 32. When the barrel bearing 7 is screwed to the stock, the socket 32 is provided at the bore 21 that passes through the stock 2. In particular, the socket 32 and the ball head 31, which is part of the rotatable threaded element 33, are received in a recess 47 of the stock 2 or stock body 20. The return 47 connects directly to bore 21 or is formed as part of bore 21.
[0050] As can be seen in particular from the Figure 4 As can be seen, the bore 21 includes a longitudinal slot 22 and / or the bore 21 is designed as a longitudinal slot 22. The longitudinal slot 22 extends in the shaft 2 or shaft body 20 along the longitudinal axis 3 of the shaft. The socket 12 of the first ball joint 10 formed in the shaft body 20 is thus elongated according to the longitudinal slot; in particular, the longitudinal slot 22 is arranged in the socket 12. The fastening device 8, in particular the two threaded elements 33, 34, is slidably received in the longitudinal slot 22, so that the fastening device 8, at least parts of the ball joints 10, 30, in particular the rod ends 11, 31 and the socket 32, and the barrel bearing 7 are slidable along the longitudinal axis 3 of the shaft relative to the barrel 6 and the shaft 2, see arrow 48.
[0051] The shaft body 20 comprises, in particular, several bores 21 and / or sockets 12, which are arranged linearly along the longitudinal axis 3 of the shaft 2 and which are designed as longitudinal slots 22. Examples are shown in Figure 4 Four longitudinal slots 22 and / or elongated sockets 12 are shown. The multiple longitudinal slots 22 and / or elongated sockets 12 are separated from each other by webs 49 of the shaft 20 or the shaft wall 20. The fastening device 8 can be arranged with the bearing 7 in or on at least two of the multiple elongated sockets 12 and / or longitudinal slots 22.
[0052] The described or illustrated embodiments serve in particular to illustrate the invention. The features disclosed in one embodiment are therefore not limited to that embodiment, but can be combined individually or together with one or more features of one of the other embodiments.
