EP2615408B1 - Mounting device for a telescopic sight in a hunting or sport weapon - Google Patents

Description

The invention relates to a mounting device for a riflescope in a hunting or sporting weapon according to the preamble of patent claim 1.

Such a mounting device is, for example, with the subject of EP 1 734 330 B1 known. In this known mounting device, a base rail is embedded in the lock box of the weapon, which is connected via positive stops and a clamping element with a telescopic mounting rail carrying the scope.

The clamping element consists of a clamping lever which carries arranged in the region of the axis of rotation, radially outwardly directed clamping wing, at the free ends of wedge surfaces are arranged under the undercuts engage in the weapon-side base rail and are clamped by rotation of the clamping lever with the weapon-side base rail.

To set the clamping force a threaded bushing is arranged in the mounting rail and the threaded pin of the pivot lever is screwed into the threaded bushing of the mounting rail. Upon rotation of the clamping lever so that at the same time the thread adjustment is adjusted in the threaded bushing, so that thereby the clamping force is amplified. When mounted, the clamping wings engage under the undercut in the base rail.

Such a mounting device utilizes a mounting rail having front and rear ball pans spaced apart from the clamping device into which the weapon-side base rail engages.

The fact that the base rail is embedded in the closure box of the weapon, resulting in a small mounting width and therefore a small mounting surface. This has the disadvantage that the mounting rail is unstably fixed on the narrow base rail on the weapon and mounted on the mounting rail riflescope the required shot precision does not provide optical sighting through the scope.
Another disadvantage of the arrangement is that the hemispherical alignment elements on the underside of the rifle scope side mounting device, which are arranged front and rear with respect to the centrally located clamping device, a superior precision in the attachment of the mounting device on the weapon can not be achieved.
By acting on the weapon barrel recoil of the explosive charge there is a tendency that the rifle scope-side mounting device is lifted with their hemispherical alignment of the also hemispherical receiving elements in the gun-side base rail against the clamping force and beyond the clamping device partially and no longer returns exactly in the same basic position. This is also because the clamping element exerts only a force acting perpendicular to the surface of the weapon-side base rail clamping force and not an additional displacement force which acts against the attacks. It lacks So completely, the limiting in the axial direction positive stops. Here, therefore, there is the disadvantage of lack of precision, especially at high recoil forces and multiple firing.

With the subject of DE 103 03 002 A1 Another mounting device has become known in which instead of a single clamping bolt now two spaced apart clamping bolts are provided, which are engageable with bottom clamping wings and wedge surfaces arranged there in associated wedge-shaped recesses on the opposite body for engagement and jammed there.

Disadvantage of this arrangement is that two spaced clamping bolts must be operated in parallel, which is associated with an increased operating effort.

With the DE 74 31 828 U1 or the US 4 205 473 A1 is another known clamping device, which also has two parallel and separately operable clamping screws, each clamping screw forms a clamping recess, which is engageable with an associated clamping recess in the opposite part and clamped there. Disadvantage of this arrangement is again that two different clamping means must be operated.

With the DE 198 10 038 C1 discloses a mounting device for a lever pivot mounting, wherein the locking lever has an integrated pawl.

The DE 38 20 471 A1 discloses a mounting device for a riflescope on a hunting or sporting weapon with a firearm side mounting assembly with a base rail and connected thereto via at least one clamping element, riflescope side mounting rail, wherein the operation of the clamping element at least one perpendicular to the surface of the two rails acting clamping force can be generated.

The invention is therefore based on the object to form a mounting device for a riflescope mounting on a hunting or sports rifle so that at a much higher precision - even with high recoil forces - always a precise, repeatable clamping position of the riflescope is guaranteed on the hunting rifle.

To solve the problem, the invention is characterized by the technical teaching of claim 1.

An essential feature of the invention is that weapon side a base rail is attached to the weapon, that the base rail is positively connected via a parting plane with a mounting rail arranged above it, which mounting rail is firmly connected via associated clamps or other fasteners to the rifle scope and that in the area connected to the weapon base rail a clamping screw rotatable in the Base rail is held, which is connected to a clamping bolt which carries at least one wedge recess, which wedge recess can be brought upon rotation of the clamping screw in frictional engagement with an associated annular groove of a stud bolt, which is attached to the rifle scope side mounting rail.
With the given clamping device, a completely new clamping principle between an armside base rail and a riflescope-side mounting rail is achieved because a laterally arranged on the base rail clamping screw is present, which carries an approximately horizontal clamping bolt, said clamping bolt has a wedge recess, which upon rotation the clamping bolt with a mounted in the riflescope side mounting rail stud bolt can be brought into non-positive influence.

By means of the clamping device according to the invention, the stud screw which is preferably fastened in the riflescope-side mounting rail is pulled onto the weapon-side base rail and simultaneously displaced in the longitudinal direction of the weapon so that a plurality of interlocking elements arranged between the weapon-side base rail and the riflescope-side mounting rail between the weapon-side base rail and the rifle scope side mounting rail are brought into mutual engagement.

The invention provides in a kinematic reversal, that the clamping screw is arranged in the rifle scope side mounting rail and the stud in the weapon-side base rail.

This results in an excellent position assurance of the weapon-side base rail on the riflescope-side mounting rail and thus a reliable, wear-free and repeatable transmission of the recoil forces is ensured by the gun-side base rail on the rifle scope side mounting rail.

This repeating accuracy is significantly improved after firing, because it is provided according to the invention that the positive connection between the gun side rail and the riflescope side mounting rail is present only at a certain point of the clamping device, while at the other, spaced therefrom a game is present, so that Clamping device according to the invention always ensures that the gun-side base rail is pressed with the clamping device against the rifle scope side mounting rail, in the sense of a clamping downward movement and a thrust movement in the longitudinal direction.

Thus, the riflescope-side mounting rail is always pushed in the sense of acting in the longitudinal direction of the riflescope side mounting rail pushing movement against the gun-side base rail until there is a positive stop comes to rest, so that an excellent repeat accuracy is given when mounting a riflescope.

Another feature of the invention is that the bolt connected to the rifle scope side mounting rail is designed to be adjustable in its longitudinal extent for the purpose of setting the clamping force.

The stud has for this purpose an annular groove, which is preferably formed circumferentially round. In the annular groove engages the associated wedge recess in the region of the clamping bolt of the clamping screw.

The stud bolt is designed to be adjustable in its axial mounting on the rifle scope side mounting rail by a thread is arranged on the outer circumference of the stud bolt, which is screwed into an associated thread in the region of a threaded bore of the mounting rail. If the stud bolt is rotated with a suitable tool, this tool engages in a tool holder in the head of the stud, thus the height of the annular groove of this stud is changed compared to the wedge recess in the clamping bolt of the clamping screw. By adjusting the height of the annular groove thus the clamping force can be adjusted continuously.

It is particularly advantageous that the tool holder for adjusting the clamping position of the stud bolt is accessible from the bottom of the mounting rail ago.

To adjust the clamping force, the mounting rail must be removed from the base rail to then retract with a suitable tool in the tool holder on the head of the stud and to turn this stud in the desired manner in its threaded hole.

The selected twist position of the stud bolt can be set with a lock screw.

In another embodiment, it is also provided that the Verdrehlage the clamping screw is possible only in certain angular ranges. For this purpose, it is provided that receiving bores are formed on the back of the head of the clamping screw and this engages in the receiving bore a spring-loaded ball of an index pin. The spring-loaded index catch ensures that the clamping screw can only be rotated over an angular range of, for example, 180 degrees.

The wedging serving wedge recess in the clamping bolt of the clamping screw is designed as Übertotpunkt surface. This means that the clamping screw can only ever be turned by an angle of e.g. 180 degrees is rotatable so as to get either from a defined open position to a defined closed position or vice versa.

This ensures that there is always an optimal clamping, without the risk that the two mutually associated parts (clamping screw and studs) could be due to one another due to insufficient clamping force.

By the axial attachment of the stud bolt is infinitely adjustable and lockable, wear can thus be avoided even with continuous use, because it must be achieved only by rotation of the stud bolt (and its clamping the serving annular groove) another axial position of the stud associated annular groove to always ensure a consistent clamping force even with high wear or longer life of the entire mounting device.

According to the invention, a dovetail-like guide groove is fastened to the weapon with a plurality of guideways, which is fastened with a base rail fastened thereto and having a dovetail-shaped groove. Because of the use of an arms-side base rail on the weapon is fixed and not embedded in the weapon, results in a more stable attachment between the weapon and the base rail mounted thereon. The base rail can thereby be made wider and is thus more stable against tipping.

The subject of the present invention results not only from the subject matter of the individual claims, but also from the combination of the individual claims with each other.

All information and features disclosed in the documents, including the abstract, in particular the spatial design shown in the drawings, are claimed to be essential to the invention insofar as they are novel individually or in combination with respect to the prior art.

In the following, the invention will be explained in more detail with reference to a drawing which merely represents one embodiment. Here are from the drawings and their description further features essential to the invention and advantages of the invention.

The telescopic sight (1) according to FIG. 1 is fixed by means of clamps (13) on a rifle scope side mounting rail (4). The entire mounting device (2) accordingly consists of a gun-mounted base rail (3) and a parting line (5) connected thereto mounting rail (4), which via the clamps (13) or other equivalent and not shown fastening means the scope ( 1) carries.

In the illustrated embodiment according to the FIGS. 1 and 2 the fastening device consists of clamps (13), to which the invention is not limited. In FIG. 1 the firing direction (41) is entered.

The positive connection between the gun-side base rail (3) and the rifle scope side mounting rail (4) consists of two spaced spring plates (6), (7), which are arranged in mounting rails and in associated recesses in the upper side of the weapon-side base rail (3) engage and there are positively locked.

It is important that the front spring plate (6) receives the recoil in the direction of arrow (38) between the gun-side base rail (3) and the rifle scope side mounting rail (4), while in the region of the rear spring plate (7) is given an axial clearance.

It is essential in the invention that, upon actuation of the clamping device, which in the embodiment shown consists of a laterally actuable clamping screw (10) with a molded handle (11) which cooperates with a mounting rail side stud bolt (12), an axial displacement of the rifle scope side mounting rail (4) against the weapon-side base rail (3) in the axial direction of the arrow (38), so that a positive engagement of the stops in the region of the front spring plate (6) is given.

At the same time the riflescope-side mounting rail (4) is pulled down on the gun-side base rail (3) in the direction of arrow (40) and fixed clamping by pressing the clamping device.

It thus comes to a displacement and a pulling movement and these two movements are superimposed upon actuation of the clamping device according to the invention.

It is also stated that the clamping screw (10) and its handle (11) are arranged in the region of a recess (8) on the side of the weapon-side base rail (3). The same illustration shows the FIG. 2 in which the in FIG. 1 explained parts are shown in an enlarged scale.

The spring plates (6), (7) are arranged on the underside of the rifle scope-side mounting rail (4) and engage in associated recesses on the upper side of the weapon-side base rail (3).

However, the invention is not limited thereto; it is also possible to provide the kinematic reversal, namely that the spring plates (6), (7) are arranged on the upper side of the weapon-side base rail (3) and engage in the associated recess on the underside of the rifle scope-side mounting rail (4).

The FIG. 3 shows the top of the gun-side base rail (3) with removed scope (1). In the middle area is a longitudinal direction formed through continuous sighting channel (14), so that when the scope is removed and the rifle scope side mounting rail (4) is missing, nevertheless a sighting for the purpose of firing through the sighting channel (14) is possible therethrough. The entire mounting device thus has a low height when the scope (1) is removed.

Furthermore, it is off FIG. 3 recognizable that in the top of the weapon-side base rail (3), the receiving grooves (16) for the engagement of the spring plates (6), (7) are arranged.

In the region of the clamping device, a preferably continuous recess (15) is arranged, in which the laterally to be described mounting rail stud bolt (12) engages and with a material einstückig and rotationally fixed to the clamping screw (10) connected clamping bolt (9) can be brought into force-fluid engagement.

The FIG. 4 shows the underside of the mounting rail (4). In the bottom, a recessed, longitudinally extending pocket (22) is formed, which is associated with a counter surface at the top of the weapon-side base rail (3). The pocket (22) forms an exemption for the clamping screw 10 engaging in this space. The two parts can be locked by engaging the two spring plates (6, 7) in the associated counter-grooves (16).

There are arranged on the rail side spring ball devices (17) - the better graphical representation in due FIG. 4 above the mounting rail (4) are shown - present, which ensure a lateral centering of the weapon-side base rail (3) with respect to the rifle scope side mounting rail (4).

The FIG. 4 shows at hidden bottom rail (3), the underside of the gun-side mounting rail (4). It is only shown in a simplified drawing, as the clamping device works, but with the clamping device, consisting of the clamping screw (10) and one with the clamping screw (10) cooperating index pin (20) of a spring (21) is biased in the weapon-side base rail (3) are arranged.

Only the stud bolt (12) forming the other half of the clamp is mounted in the mounting rail (4).

To FIG. 4 are in the region of the front spring plate (6) front stops (24) on the spring plate (6) arranged with the associated stops on the receiving groove (16) in the base rail (3) according to FIG. 3 cooperate, with internal or lateral stops (23) are formed.

The rear spring plate (7) has only lateral stops (23) and forms in the longitudinal direction of an axial clearance, so that a statically determined association between the weapon-side base rail (3) and the rifle scope side mounting rail (4) is given. The inner or side stops can be formed by spring-loaded index balls, which are supported on the respective opposite part.

The FIG. 4 further shows that the stud (12) carries at its head a reachable from the bottom of the tool holder (18). Furthermore, it can be seen that the clamping screw (10) is integrally connected to the clamping bolt (9) and in the region of the clamping bolt a wedge recess (19) is provided with the later still to be explained annular groove (39) in the stud bolt (12) the power liquid Jamming of base rail (3) to the mounting rail (4) yields.

The clamping screw (10) is rotatable in the direction of rotation (26) in the direction of rotation (25), wherein two rotational positions offset by 180 degrees from the open position to the closed position are provided. Both rotational positions are limited by the index pin (20) and the associated spring (21).

In FIG. 5 It is shown that the index pin (20) with an unspecified ball, which is biased by a spring (21), optionally in associated Receiving holes (34) on the back of the head (33) of the clamping screw (10) is engageable so as to limit the two Verdrehlagen the clamping screw (10).

Furthermore, it can be seen that the twisting position of the mounting rail side fastened and adjustably held therein stud bolt (12) by a lock screw (29) can be locked. The lock screw is screwed into the mounting rail (4) in a transverse bore and exerts upon rotation in the direction of arrow (30) with its front side a pressure on the outside of the thread (27) of the stud bolt (12). This fixes its twisting position.

The stud bolt (12) is screwed into a threaded hole (28) in the region of the mounting rail (4).

The FIG. 6 shows the engagement of the wedge recess (19) in the clamping bolt (9) of the clamping screw (10) in an associated annular groove (39) of the stud bolt (12).

The pivot bearing of the clamping bolt (9) of the clamping screw (10) is formed in that the clamping screw (10) at the rear end of the clamping bolt (9) has an annular groove (32), in which a cylindrical pin (31) engages, in the base rail (3) is used. The cylinder pin (31) secures the clamping bolt (9) of the clamping screw (10) from falling out in the direction of the longitudinal axis of the clamping bolt (9).

The FIG. 7 shows further details of the device. The spring plates (6), (7) are fixed to the underside of the rifle scope side mounting rail (4) and engage in the associated recesses (16) at the top of the base rail. The cylindrical pin (31) is otherwise held in the region of a transverse bore (35) in the base rail (3) (see FIG. 9 ).

The FIG. 8 shows that in accordance with the wedge recess (19) FIG ) an exemption (36) connects, so that the first clamping action in the rotation of the clamping bolt (9) by engagement of the exemption (36) on Circumference of the annular groove (39) in the region of the stud bolt (12) takes place and thereby already a first preliminary clamping is given. With increasing further rotation of the clamping bolt (9), the release (36) goes into the wedge recess (19), via which then the preliminary clamping force is increased by a multiple until reaching the final clamping force.

The FIG. 10 shows the adjustment of the clamping force in that the stud bolt (12) in the mounting rail (4) in the region of the aforementioned threaded bore (28) with its thread (27) is accommodated.

By engaging a suitable tool in the downwardly accessible tool holder (18) of the stud bolt (12) this can be rotated in the direction of arrow (37) and thus its altitude or its axial adjustment in the threaded bore (28) can be adjusted.

Accordingly, the annular groove (39) comes in juxtaposition or in this axially offset comparison to the wedge recess (19) in the clamping bolt (9). Thus, the clamping force can be adjusted continuously.

After the twisting of the stud bolt (12) with its thread (27) in the threaded bore (28) this is determined by means of the lock screw (29).

Advantage of the invention is a high-load-transmitting precise mounting device (2), which always returns to its basic position even with repeated transmission of firing loads, because it is clamped only between two stop positions, namely once between the spring plate (6) and the associated receiving groove (16 ) in the opposite part and on the other by the clamping device, consisting of the clamping screw (10) with the clamping bolt (9) and the oppositely arranged stud bolt (12). Upon actuation of the clamping device, a thrust force is generated in the longitudinal direction of the mounting rail (4) and at the same time a contact force in the vertical direction thereto. <B><u> Drawing Legend </ u></b> 1 Scope 22 bag 2 mounter 23 Stop (side) 3 Base rail (weapon) 24 Stop (front side) 4 Mounting rail (riflescope) 25 axis of rotation 5 parting plane 26 arrow 6 spring plate 27 Thread (of 12) 7 spring plate 28 Threaded hole (in 4) 8th recess 29 lock screw 9 clamping bolts 30 arrow 10 clamping screw 31 straight pin 11 handle 32 Ring groove (from 9) 12 studs 33 Head (out of 10) 13 clamp 34 location hole 14 visor gutter 35 cross hole 15 Recess (insertion bevel) 36 exemption 16 Receiving groove (for 6, 7) 37 arrow 17 Spring ball device 38 arrow 18 tool holder 39 Ring groove (stud bolt 12) 19 key recess 40 arrow 20 index pin 41 weft direction 21 feather
