Description

The invention relates to a mounting device for a telescopic sight on a hunting or sporting weapon according to the preamble of patent claim 1, with such a mounting device already being known from the same applicant EP 2 615 408 B1 is known.

The present invention constitutes the construction of the mounting device in the aforesaid EP 2 615 408 B1 continued in a special way, and therefore the functionally identical parts of the present assembly device were provided with the same reference numerals in the drawings of the present description of the invention, as in the EP 2 615 408 B1 were used. For the rest, reference is made to the disclosure of this publication, which represents the basic principle of a mounting device for a telescopic sight.

All the same parts in the later drawing description therefore have the same function as they already have in the EP 2 615 408 B1 was described.

The known mounting device mentioned is characterized in that there is a fastening arrangement on the gun side with a base rail and a mounting rail on the rifle scope side connected thereto via at least one locking element, wherein at least one clamping force acting perpendicularly to the surface of the two rails can be generated when the locking element is actuated and preferably a form-fitting connection between the two rails consists of two spring shackles arranged at a distance from one another, with the locking element being held rotatably in one rail which is connected to a clamping shaft which has at least one wedge recess, with the clamping shaft rotating in a non-positive manner when the locking element is rotated Engagement with an associated annular groove-shaped recess of a stud can be brought on the is attached to the opposite rail, with the locking element also generating a displacement force acting in the axial direction (longitudinal direction) of the two rails during the clamping or locking between the weapon-side base rail and the mounting rail held thereon in a form-fitting manner, so that preferably a form-fitting contact of the stops in the area of Spring tabs is given.

The above construction according to the EP 2 615 408 B1 has proven itself on a large scale. It ensured an easy-to-operate attachment between a base rail on the weapon side and a mounting rail connected to the telescopic sight, because the two rails could be positively connected to one another with a single one-handed rotary operation of the locking element and play between the parts was definitely excluded. Due to the push-pull movement between the rails during assembly, the push and push forces occurring during the firing of the shot could be absorbed by the assembly device in a favorable manner, so that this assembly device has become established in multiple versions on the market.

Experiments with such a mounting device has shown that improvements are possible because - among other things - in the EP 2 615 408 B1 provided with the reference numeral 12 studs can be improved.

In the EP 2 615 408 B1 the stud bolt was designed with its bolt-side end as a threaded bolt which could more or less be screwed into an associated threaded hole in the mounting rail.

Thus, before joining the two rails, the height of the stud above the longitudinal groove of the mounting rail could first be adjusted by turning the stud, which could be more or less screwed into its threaded recess in the threaded hole of the mounting rail due to the rotation.

The EP 2 615 408 B1 a scale on the upper side of the stud, which could thus be turned by different angles according to the scale in order to determine its screw-in depth, which also keeps the torque of the jamming or locking always the same.

Experiments have shown that a significant optimization of this known mounting device would be possible if the mounting rail-side threaded bore is dispensed with, which also requires a certain minimum axial length in order to prevent the external thread on the threaded side of the stud bolt from tearing out of the mounting rail-side receiving bore.

A certain minimum guide length in the mounting hole was also necessary in order to prevent the threaded end of the stud bolt from tilting in this mounting hole. However, this had the disadvantage that the mounting rail on the telescopic sight had to have a certain overall height that could not be undercut in order to provide the receiving bore for the threaded end of the stud with a minimal axial length that protected against tearing out and tilting.

Another disadvantage associated with the use of a threaded screw connection between the stud bolt and the scope-side mounting rail was that there was unavoidable axial play in the area of the threaded hole.

The screw-in depth of the stud bolt was also used to compensate for manufacturing inaccuracies in order to achieve a specific, repeatable back focus between the mounting rail on the scope side and the base rail on the weapon side.

A one-time adjustment of the screwing-in depth of the stud bolt in the mounting rail on the telescopic sight was achieved in that manufacturing tolerances in the contact surfaces between the base rail on the weapon side and the mounting rail on the telescopic sight were compensated.

The invention is based on the object, a mounting device of the type mentioned in accordance with EP 2 615 408 B1 further developed in such a way that a mounting rail on the telescopic sight side that is significantly reduced in overall height can be used and that a manual adjustability of a stud is no longer necessary.

The invention is characterized by the technical teaching of claim 1 in order to solve the task at hand.

In an advantageous embodiment, a mounting device for a telescopic sight on a hunting or sporting weapon is therefore proposed, in which the connection between the rails which are parallel to one another and are to be connected to one another in a form-fitting manner is formed by at least one axial stud bolt which is arranged on one rail and with a clamping shaft which cooperates with the stud bolt and which is rotatably mounted on the other rail.

In the embodiment according to the invention, the stud bolt is mounted in a spring-loaded manner in its axial longitudinal extent in a guide part on the mounting rail side, so that it can be moved axially and secured against tilting. The at least one axially spring-biased stud bolt thereby forms the at least one spring-biased connection between the associated rails. Instead of a threaded stud like the one in our own EP 2 615 408 B1 known is omitted. Instead of the known threaded screw connection, at least one spring-loaded stud is provided.

In a second embodiment, not covered by the invention, the kinematic reversal of the first embodiment is provided. In this case, the spring-loaded displacement bearing of the stud bolt is omitted. This is then rather immovably attached to a rail part. Instead, the spring preload on the stud bolts is achieved by means of a spring-loaded mounting of the clamping shaft. In this case, the two bearing ends of the clamping shaft are accommodated in springs, so that the clamping shaft extends in the axial direction of the longitudinal direction of the stud bolt is spring-loaded. When the advantages and features of the first embodiment are described in the following description, this also applies analogously to the second embodiment.

Both versions have the advantage that there is no threaded screw connection between a stud and the mounting rail-side mounting rail and instead a floating, axially displaceable, resilient guide of the stud is provided in an associated receiving bore.

This has the advantage that because there is no threaded screw connection between the stud bolt and the mounting rail on the telescopic sight, fine adjustment of the screw-in depth of the stud bolt is no longer required because - in the first embodiment - it is spring-mounted in the axial direction and is therefore a previously set spring force applies to the clamping shaft of the locking element. The stud is positively connected against this spring force with the locking element, it being the same as in FIG EP 2 615 408 B1 there is an axial displacement force acting between the two rails. When clamping or locking between the base rail on the weapon side and the mounting rail held thereon in a form-fitting manner, a displacement force acting in the axial direction of the two rails is therefore additionally generated, so that, for example, there is a form-fitting contact of stops in the area of a front spring plate.

Because of the spring-loaded displacement bearing of the stud, there is no fine adjustment of the thread - as explained - and the correct dimension is always given, because the two associated rails are always attracted to one another with the same force due to the spring force and this force is compensated by the spring force on the stud is effected.

In a preferred embodiment of the invention, it is provided that the spring mounting of the stay bolt takes place on the basis of a plate spring or on the basis of a set of plate springs.

In other configurations, an elastomer spring, a helical compression spring or other force accumulator can also be used instead of a disc spring.

In another embodiment, it can also be provided that the spring force on the stud bolt, which acts on the stud bolt in the axial direction, is exerted by hydraulic or pneumatic prestressing.

A feature of all embodiments is that the two rails are attracted to one another with a set spring force, and this also compensates for manufacturing tolerances that had to be compensated for in the prior art by fine adjustment of the screw-in depth of the stud bolt, which can be omitted according to the present invention.

As in your own EP 2 615 408 B1 described, it does not depend on the mutual assignment of the terms of weapon-side base rail and scope-side mounting rail. The parts mentioned can also be mounted in kinematic reversal, so that, for example, the mounting rail on the telescopic sight side is mounted on the weapon and the base rail on the weapon side on the telescopic sight. This was already the subject of EP 2 615 408 B1 and is also intended to apply to the present invention. The terms “base rail (on the weapon side)” and “mounting rail (on the telescopic sight side)” can therefore be interchanged throughout the text of this description of the invention.

Furthermore, the invention is not limited to using a single stud with the new features according to the invention. In another embodiment, it can be provided that two spaced-apart studs are arranged on one of the rails, each of the studs being spring-loaded in the axial direction in the manner described.

In a preferred embodiment of the invention, it is also provided that the stud bolt is designed as a locking bolt, which means that it a locking opening can be inserted in the area of the mounting rail on the telescopic sight and rotated by 90° with a tool, whereby it is drawn into the fastening recess via the prestressed plate spring and is fixed there.

It is therefore a bayonet-like fixing of the stud bolt in an assigned recess in the area of the mounting rail on the side of the telescopic sight, and according to a further preferred feature it is provided that after fixing the stud bolt with its key faces opposite one another at the edge, it is provided that this in its final mounting position is locked against rotation.

Such a non-rotatable locking can be done, for example, by a spring-loaded locking ball, which fixes the stud bolt in its end position and secures it against further rotation.

This means that the stud bolt is secured against rotation in a bearing pocket in the area of the mounting rail on the scope side.

According to a further feature of the invention, it is provided that for mounting the disc spring there is a pocket in the mounting rail on the side of the telescopic sight, which is also referred to as a mounting pocket in the subsequent description.

The insertion pocket is a lateral expansion of the bearing pocket provided for the plate spring, so that using the mounting pocket it is possible to insert the plate spring into the mounting pocket and to move it in the axial direction until it is in the assigned bearing pocket for the stud bolt falls in. Then the stud bolt is placed on the plate spring. The bolt-side end of the stud extends through a central recess in the plate spring and comes to rest in a guide part, which is designed as an elongated sleeve open on one side, which in a preferred embodiment is connected in one piece to the underside of the mounting rail on the telescopic sight. In a different way Execution can also be detachably attached to the mounting rail, the guide part.

By arranging a guide part that is lengthened in the axial direction and has a guide shoulder directed in the axial direction, on which an angled end shoulder is arranged in the horizontal direction, it is achieved that the stud bolt has a rotary guide practically over its entire axial length, because it is connected to its Outer circumference rests against contact surfaces in the region of the axial guide extension of the guide part and is rotatably mounted there in a load-transmitting manner.

It is therefore an external guide between the guide part, which is connected to the mounting rail, and the stay bolt, which is rotatably mounted in the guide part but can be displaced therein under spring loading.

Instead of the arrangement of such a guide part, which rests with its inner circumference in a form-fitting manner on the outer circumference of the stud bolt, other guide constructions can also be used.

In a further development of the invention, it can be provided that the guide part is replaced by an axle which is present on the angled front shoulder of the sleeve-like guide part and which engages in an associated receiving bore in the front face on the bolt-side end of the stud bolt and is slidably mounted there. With this different type of storage, the stud is guided on the pin-like cylinder extension and is simultaneously spring-loaded and displaceable on the guide extension.

Another advantage of the reduced overall height of the mounting rail on the scope side, which is due to the fact that there is no threaded screw connection between the stud bolt and the mounting rail, is that the previously multi-part spring plates, which were used as separate elements in the rails - as in the EP 2 615 408 B1 described - can be omitted, and these spring plates can now be formed directly in one piece of material on the telescopic sight-side mounting rail.

This achieves a significant weight saving and a reduction in the number of components present.

The subject matter of the present invention results not only from the subject matter of the individual patent claims, but also from the combination of the individual patent claims with one another.

Before going into the individual terms in the drawings, it is pointed out that - just like in the EP 2 615 408 B - the naming of weapon-side base rail 3 and the designation of the telescopic sight-side mounting rail 4 can be interchanged. In another embodiment, not shown in detail, it can be provided that the weapon-side base rail 3 is mounted on the telescopic sight and thus represents the telescopic sight-side rail, while conversely, the telescopic sight-side mounting rail 4 shown here can now be connected to the weapon to form the weapon-side basic rail to represent.

Merely for reasons of simplification, it is assumed in the following description that the base rail 3 on the weapon side is connected to the weapon 42 and the mounting rail 4 on the telescopic sight side is connected to the telescopic sight 1. However, as described above, this can also be done vice versa in kinematic reversal.

Because of the further function of the individual parts is on the description of the invention EP 2 615 408 B1 referred, which should be fully covered by the subject matter of the present invention.

From the figure 1 it follows that a base rail 3 on the weapon side is fastened to the upper side of the weapon 42 with fastening means (not shown in detail) and the mounting device 2 now consists of the base rail 3 on the weapon side and the mounting rail 4 on the telescopic sight side that is detachably connected thereto.

On the mounting rail 4, the telescopic sight 1 is screwed with certain fasteners that will be shown later.

An advantage of the invention lies in the fact that the overall height of the mounting rail 4 on the telescopic sight is now significantly reduced, as is indicated by the distance 68 in figure 1 is shown.

In the prior art according to EP 2 615 408 B1 the distance 68 was 50% higher, which was associated with the required greater overall height of the mounting rail 4 on the telescopic sight. This is the advantage of the invention, which is now a 50% reduced distance 68 between the weapon barrel 69 and the telescopic sight 1 is achieved.

The reduction in this distance 68 affects the ballistics less when the shot is fired, which means that the sighting axis through the telescopic sight 1 is now closer together than the weapon axis through the weapon barrel 59 . The bore axis is therefore closer to the optical axis, which is associated with great advantages when mounting the riflescope and when firing the shot.

For the sake of better clarity, the firing direction 41 is also indicated with the arrow direction 41 .

the Figures 2 to 6 show the mounted state of the mounting device 2, which means that the two rails 3, 4 assigned to one another are connected to one another firmly and positively in a load-transmitting manner, using a locking element 10, which essentially consists of a handle 11, which is non-rotatably connected to a rotatable mounted clamping shaft 9 is connected.

The two rails 3, 4 are connected to one another in the area of a parting plane 5 and - as described in the prior art - when the locking element 10 is actuated, the mounting rail 4 on the telescopic sight side is displaced in the axial direction (direction of arrow 38 and at the same time a displacement perpendicular thereto in the direction of arrow 40 reached.

Both displacements in the directions of the arrows 38, 40 lead to the form-fitting fixing of mutually spaced spring bars 7 which are integrally connected to the sides of the mounting rail 4, with spring shackles 6 being formed on their respective free ends, which are beveled to ensure a form-fitting to achieve a displacement-free system on the opposite rail.

For this purpose, the spring tabs 6 engage in associated receiving grooves 16 in the area of the base rail 3 and are mounted there in a form-fitting manner.

Accordingly, the full force between the base rail 3 on the weapon side and the mounting rail 4 on the telescopic sight side is transmitted to the receiving grooves 16 on the base rail side via the spring bars 7 and the spring tabs 6 formed thereon.

Furthermore, the Figures 2 to 4 also rudimentary attachment of the telescopic sight, because it is shown that so-called sliding blocks 13 are fixed to the mounting rail 4 with the aid of fastening screws 45, with at least one toothed rail 44 being arranged in the longitudinal groove 56 of the mounting rail 4, which is connected to a toothed rail, not shown in detail on the underside of the telescopic sight is brought into engagement in a manner secured against displacement.

The sliding blocks 13 each engage in an associated undercut groove receptacle on the telescopic sight 1 on the telescopic sight side.

The invention is not limited to the mounting of the telescopic sight 1 shown here on the mounting rail 4 on the telescopic sight side in the area of its longitudinal groove 56 . It can also be provided with a ring assembly with clamping rings, as in the subject of EP 2 615 408 B1 is shown. Likewise, all other form-fitting connections that are also detachable are possible.

There are a total of four bearing surfaces 40 lying one behind the other in the longitudinal direction between the rails 3, 4 assigned to one another, as shown in FIG figure 3 and in figure 12 shown.

The bearing surfaces 70 are therefore in the parting plane 5 between the associated rails 3, 4 and have a mutual spacing 71, as shown in figure 12 is shown.

The respective spring bar 7 engages in the space between the adjacent bearing surfaces 70 and thus forms the load-transmitting connection between the two rails 3, 4.

Due to the bearing surfaces 70 arranged at a mutual distance 71 from one another, which are spaced apart from one another in the axial direction, there is a clearance 72 in the intermediate area, in the area of which the locking element 10 is now arranged with the stud bolt 12 which is resiliently displaceable in the axial direction. Among other things, this is also in figure 12 shown.

This results in the advantage that due to the arrangement of the locking element 10 in the area of this clearance 72, the spring force of the stud bolt acts on the free underside of the mounting rail 4 and a particularly favorable contact force or transmission force on the mounting rail 4 is thereby achieved.

With a relatively low spring force of a cup spring 50, the mounting rail 4 can be fixed to the base rail 3 on the weapon side over a large area.

Out of figure 3 it also follows that the base rail 3 on the weapon side is fastened to the upper side of the weapon with the aid of fastening screws 57 .

Of course, there are also other fastening options, such as clamping levers, eccentric levers, push-on or wedge fastenings.

The stud 12 consists according to Figure 6a and 6b essentially consists of an upper, plate-shaped closure plate 46, in the area of which an actuating slot 47 for engaging a tool is arranged.

The stud bolt 12 is initially rotatably and lockably mounted with its locking plate 46 in an associated bearing pocket 51 in the area of the longitudinal groove 56 of the mounting rail 4 . Details are from the figures 6 , 6a and 6b refer to.

According to Figure 6a a bolt end 74 is integrally formed on the stud bolt 12 on the underside of the closure plate 46 and the lower face of the bolt end 74 has a certain axial distance to a Guide recess 60 according to figure 6 , which is formed in the guide part 58, which is preferably connected in one piece with the mounting rail 4 on the telescopic sight.

This guide part 58 is designed as a sleeve open on one side, the open surface of which points counter to the weft direction 41 .

This achieves an axial displacement guide for the bolt end 74 of the stay bolt 12 that is secured against tilting and canting.

The axial distance in the area of the guide recess 60 of the guide part 58 in connection with an angled front shoulder 59 of the guide part (see figure 11 ) allows an axial play of the stud bolt 12 in the guide part 58.

In the region of the guide part 58 it can therefore move in the axial direction under the action of the spring-loaded plate spring 50 and is secured against tilting.

To mount the plate spring 50, the bearing pocket 51 in the longitudinal groove 56 of the mounting rail 4 is enlarged in the axial direction by a mounting pocket 48 having the same radius and lengthened in the longitudinal direction. The two parts that merge into one another and are connected to one another, namely the storage pocket 51 and the mounting pocket 48, do merge into one another, but are separated from one another in terms of height by a shoulder.

This results in the advantage that for the assembly of the disc spring 50 it is inserted into the assembly pocket 48 and then pushed in the direction of the arrow 49 in order to fall into the recessed bearing pocket 51 for the bearing of the stud 12 .

Then the stud bolt is inserted with its bolt end 74 through the disk spring 50 and the underside of the closure plate 46 thus comes to rest on the disk spring, which is now in the region of the bearing pocket 51 .

For the bayonet-like locking of the stud 12 by rotating the locking plate 46 by 90°, it is provided that key surfaces 53 are located opposite one another on the outer circumference of the locking plate 46, which enable the stud 12 to be inserted into the bearing pocket 51 and which, when the Locking plate 46 engage in undercuts in the region of the bearing pocket 51, so that when the stud 12 is fixed correctly during assembly, the locking plate 46 prevents the stud 12 from being pushed out of the bearing pocket 51 in the upward direction.

A spring-loaded rotary lock is provided for locking the correct installation twisted position of the stud bolt 12, which figure 6 is shown in more detail. There is a transverse bore 66 in the bolt end 74 of the stud 12, in which a compression spring 65 is mounted, on which a locking ball 64 acts, which engages in an associated locking recess 75 in the manner of a spring-loaded index ball and the stud 12 against rotation secures its rotational position in the correct position.

Instead of locking the pivot bolt with a spring-loaded locking ball, other rotary locks can of course also be used, such as a feather key or a threaded guide pin, which engages in an associated recess in the stud bolt and secures it against twisting.

In the embodiment according to figure 6 , 6a, 6b It is advantageous if the plate spring 50 or a set of plate springs now engages under the stud bolt, which is held non-rotatably in its displacement position, and due to this special arrangement, the desired displacement in the arrow directions 38, 40 can be provided with the locking element 10.

For this purpose, the bolt end 74 of the stud 12 is a hollow recess 39, which in the prior art ( EP 2 615 408 B1 ) is designed as an annular groove.

This is where a further feature of the invention comes into play, that instead of an annular groove, which overall weakens the cross section of such a stud, there is now a one-sided hollow recess 39, which has the advantage that the round material cross-section of the bolt end 74 is replaced by the one-sided hollow recess 39 according to Figure 6b is only slightly weakened. The stud bolt 12 can thus also transmit higher loads than in the prior art. According to figure 6 is the hollow recess 39 shaped as a circular section surface and consists according to Figure 6a of two surfaces intersecting at an angle, so that the hollow recess 39 forms a wedge recess in the transverse direction to the longitudinal extent of the bolt end 74 by two wedge recesses set at an angle to one another.

The stud bolt 12 forms with its non-weakened bolt end 74 in cross section (see Figure 6b ) an enlarged contact surface 62 (see figure 11 ) this bolt end 74 on the guide part 58, as shown in figure 11 is shown.

The stud bolt 12 is accordingly guided over a greater axial length in the direction of displacement, which is associated with increased security against tilting, which could not be achieved with threaded screw connections according to the prior art.

A further advantage arises according to Figure 6b in that an enlarged load-transmitting surface for the engagement of the clamping shaft 9 is achieved through the hollow recess 39 which is open on one side.

A locking element 10 with a clamping shaft 9 formed thereon is off Figure 6c refer to. The hollow recess 39 of the stud 12 engages in the wedge recess 19 of the clamping shaft 9 in a non-positive and positive manner. A clearance 36 follows the wedge recess 19 , so that a first clamping effect occurs when the clamping shaft 9 rotates when it engages in the clearance 36 in the wedge-shaped and eccentric hollow recess 39 at the bolt end 74 of the stud 12 . With increasing further rotation of the clamping shaft 9, the exemption 36 merges into the wedge recess 19, via which the preliminary clamping force is then multiplied to achieve the final clamping force is increased. The bolt end 74 of the stud bolt 12 is prestressed against the spring force of the disk spring 50 in the direction of its longitudinal extension with a high force.

It is advantageous here if the clamping shaft 9 lies in a clamping shaft bore 73 which is designed eccentrically in relation to the central axis of the hollow recess 39 . Is in figure 6 shown.

Upon rotation of the clamping shaft 9 counterclockwise according to figure 6 the stud bolt 12 is thus pulled downwards in the direction of the arrow 55 against the force of the disc spring 50, with the displacement path 63 in the region of the guide recess 60 being able to be utilized.

As previously shown, the guide part 58 has a sleeve-like guide projection 61 which extends in the axial direction and opens on one side.

In the body of the mounting rail 4 there is an elongated hole 67 which enables the locking ball 64 and the compression spring 65 to be mounted.

The slot 67 is an extension of the hole. the figure 6 shows that a bearing bore 50 is arranged in the mounting rail 4 as an extension of the guide part 58, in which the stud bolt 12 is mounted in a rotatable and spring-loaded, displaceable manner. The rotation of the stud only occurs during assembly. After assembly, it is secured against rotation by the spring-loaded locking ball 64 and can only be displaced in the axial direction of its bolt end 74 by spring loading.

With the present invention, the advantage is therefore achieved that with a greatly reduced overall height of one rail 4, a special type of fastening of a stud bolt 12 is now provided, which is no longer designed as a threaded screw connection, but as a spring-loaded bayonet screw connection, which represents a significant advantage over the prior art.

The spring-loaded bayonet connection shown represents a particularly elegant assembly of the stud bolt 12, because it engages with its locking plate 46 in associated undercuts in the area of the assembly rail and, after assembly, can only be moved spring-loaded in the axial direction (the direction of its longitudinal extent) and secured against rotation is.

In another embodiment, not shown in the drawing, it can be provided that instead of a bayonet screw connection for securing the axial position of the stud 12, there is a simple, one-way rotatable fastening plate arranged on the mounting rail side, which in the working position holds the head of the stud upwards in the bearing pocket 51 covered towards and which is fastened to the mounting rail with the aid of a fastening screw and can be rotated parallel to the surface of the mounting rail 4 . In the assembly position, the fastening plate is pivoted away from the bearing pocket 51 so that the stud bolt can be introduced into the bearing bore 52. In the working position, the mounting plate is pivoted over the bearing pocket 51 and covers the head of the stud 12, namely its locking plate 46, from the top. This type of attachment also secures the stud bolt 12 from falling out of the guide part 58 upwards.

In this solution, the rotary screw fastening of the stud 12 is omitted. Rather, the stud is inserted directly in the direction of its longitudinal extent into the bearing bore 52 and fixed with the aid of the pivotable fastening plate located above it.

In principle, the bayonet screw connection can also be omitted completely, so that the stud 12 is only inserted in the direction of its longitudinal extent in the bearing bore 52 on the guide part 58 and the previously described rotary lock would then also ensure the axial displacement locking of the stud 12. It therefore does not require a bayonet screw connection to prevent it from falling out, nor does it require a rotatable mounting plate.

The underside of the mounted telescopic sight 1 then secures the stud 12 from falling out in the direction of its longitudinal extension upwards, because suitable contact surfaces are provided on the underside of the telescopic sight.

A tongue and groove guide or a dovetail guide arranged in the longitudinal direction of the stud 12 on or in the bearing pocket 51 and/or the guide part 58 can also be used as a torsion-proof longitudinal guide for the stud 12 in the bearing pocket 51 and/or in the guide part 58 be provided.

The invention is therefore not dependent on a bayonet screw connection of the stud to secure it against falling out, but prefers such a design because it is a particularly elegant and simple attachment of such a stud 12 .
