(17) Before addressing the individual terms in the drawings, it is noted that—just like in EP 2 615 408 B—the designation of the weapon-side basic rail 3 and the designation of the telescopic sight-side mounting rail 4 can be interchanged. It can be provided in another embodiment, not shown in detail, 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 in order to represent the weapon-side base rail.

(18) Merely for the sake of simplicity, it is assumed in the following description that the weapon-side base rail 3 is connected to the weapon 42 and the telescopic sight-side mounting rail 4 is connected to the telescopic sight 1. However, as described above, this can also be done the other way around in a kinematic reversal.

(19) Because of the further function of the individual parts, reference is made to the description of the invention in EP 2 615 408 B1, which is intended to be fully comprised by the subject matter of the present invention.

(20) FIG. 1 shows that a weapon-side base rail 3 is attached to the top of the weapon 42 with attachment means (not shown in detail) and the mounting device 2 now consists of the weapon-side base rail 3 and the telescopic sight-side mounting rail 4 detachably connected to it.

(21) On the mounting rail 4, the telescopic sight 1 is screwed to certain attachment elements which will be shown later.

(22) An advantage of the invention lies in the fact that the structural height of the telescopic sight-side mounting rail 4 is now reduced substantially, as represented by the distance 68 in FIG. 1.

(23) In the prior art according to EP 2 615 408 B1, the distance 68 was 50% higher, which was associated with the required greater structural height of the telescopic sight-side mounting rail 4.

(24) This is the advantage of the invention, which now achieves a 50% reduced distance 68 between the weapon barrel 69 and the telescopic sight 1.

(25) By reducing this distance 68, the ballistics is less impacted when a shot is fired, which means that the sighting axis through the telescopic sight 1 compared to the weapon axis through the weapon barrel 59 are now closer together. The barrel bore axis is therefore situated closer to the optical axis, which is associated with great advantages when assembling the telescopic sight and when firing a shot.

(26) For the sake of clarity, the firing direction 41 is also shown with the arrow direction 41.

(27) FIGS. 2 to 6 show the assembled state of the mounting device 2, which means that the two mutually associated rails 3, 4 are load-transmitting firmly and positively connected to each other, using a locking element 10, which substantially consists of a handle 11, which is non-rotatably connected to a rotatably mounted clamping shaft 9.

(28) The two rails 3, 4 are connected to each other in the area of a parting plane 5, and—as described in the prior art—upon actuation of the locking element 10, resulting in a displacement of the telescopic sight-side mounting rail 4 in the axial direction (arrow direction 38) and simultaneously in a displacement perpendicular thereto in the arrow direction 40.

(29) Both displacements in the arrow directions 38, 40 lead to the positive fixing of spaced-apart spring bars 7 which are connected materially in one piece to the sides of the mounting rail 4, wherein at their respective free ends spring tabs 6 are molded which are beveled in order to achieve a positive, displacement-free bearing against the opposite rail.

(30) For this purpose, the spring tabs 6 engage in assigned receiving grooves 16 in the area of the base rail 3 and are mounted there positively.

(31) Accordingly, the full force between the weapon-side base rail 3 and the telescopic sight-side mounting rail 4 is transmitted via the spring tabs 7 and the spring tabs 6 molded thereto to the base rail-side receiving grooves 16.

(32) Furthermore, FIGS. 2 to 4 also show to some extent the attachment of the telescopic sight, because it is shown that so-called slot nuts 13 are fixed to the mounting rail 4 with the aid of attachment screws 45, with at least one toothed rail 44 being arranged in the longitudinal groove 56 of the mounting rail 4, which is brought into engagement with a toothed rail (not shown) on the underside of the telescopic sight so as to be secured against displacement.

(33) The groove nuts 13 each engage in an assigned telescopic sight-side undercut groove receptacle on the on the telescopic sight 1.

(34) The invention is not limited to the attachment of the telescopic sight 1 shown here on the telescopic sight-side mounting rail 4 in the area of its longitudinal groove 56. A ring mounting with clamping rings can also be provided, as shown in the subject matter of EP 2 615 408 B1. All other positive connections that are also detachable are also possible.

(35) There are a total of four sequential bearing surfaces 70 in the longitudinal direction between the mutually assigned rails 3, 4, as shown in FIG. 3 and in FIG. 12.

(36) Accordingly, the bearing surfaces 70 are situated in the parting plane 5 between the rails 3, 4 assigned to one another and are spaced apart 71 from one another, as shown in FIG. 12.

(37) 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.

(38) As a result of the spaced-apart 71 bearing surfaces 70, which are spaced apart from each other in the axial direction, there is a release 72 in the intermediate area, in the area of which the locking element 10 is arranged with the stay bolt 12 that is resiliently displaceable in the axial direction. This is also shown, inter alia, in FIG. 12.

(39) This results in the advantage that due to the arrangement of the locking element 10 in the area of this release 72, the spring force of the stay bolt acts on the free underside of the mounting rail 4 and thereby achieving a particularly favorable contact force or transmission force on the mounting rail 4.

(40) With a relatively low spring force of a disc spring 50, a large-area fixing of the mounting rail 4 on the weapon-side base rail 3 can thus be achieved.

(41) FIG. 3 also shows that the weapon-side base rail 3 is attached to the top of the weapon with the aid of attachment screws 57.

(42) There are, of course, other attachment options also, such as, for example, clamping levers, eccentric levers, push-on or wedge attachments.

(43) According to FIGS. 6a and 6b, the stay bolt 12 consists substantially of an upper, plate-shaped closing plate 46, in the area of which an actuating slot 47 is arranged for the engagement of a tool.

(44) The stay bolt 12 is initially rotatably and lockably mounted with its closing plate 46 in an assigned bearing pocket 51 in the area of the longitudinal groove 56 of the mounting rail 4. Details can be found in FIGS. 6, 6a and 6b.

(45) According to FIG. 6a, a bolt end 74 is materially in one piece molded to the stay bolt 12 at the underside of the closing plate 46, and the lower end face of the bolt end 74 has a certain axial distance to a guide recess 60 according to FIG. 6, which is formed in the guide part 58 which is preferably connected materially in one piece to the telescopic sight-side mounting rail 4.

(46) This guide part 58 is formed as a sleeve open on one side, the open surface of which points against the firing direction 41.

(47) In this way, an axial displacement guide secured against tilting and canting is achieved for the bolt end 74 of the stay bolt 12.

(48) The axial distance in the area of the guide recess 60 of the guide part 58 in connection with the angled end projection 59 of the guide part (see FIG. 11) allows an axial movement play of the stay bolt 12 in the guide part 58.

(49) Said stay bolt 12 can therefore move spring-loaded, spring-loaded under the action of the disc spring 50, and secured against tilting, in the axial direction in the area of the guide part 58.

(50) For the mounting of the disc spring 50, the bearing pocket 51 in the longitudinal groove 56 of the mounting rail 4 is enlarged by a mounting pocket 48 having the same radius and longitudinally elongated in the axial direction. The two parts that merge into one another and are connected to one another, namely the bearing pocket 51 and the mounting pocket 48, indeed merge into one another, but are separated from one another in terms of height by a shoulder.

(51) This has the advantage that, for mounting the disc spring 50, said disc spring 50 is inserted into the mounting pocket 48 and then displaced in the arrow direction 49 in order to drop into the recessed bearing pocket 51 for mounting the stay bolt 12.

(52) The stay bolt end 74 is then pushed through the disc spring 50 and the underside of the closing plate 46 comes to bear against the disc spring, which is now situated in the area of the bearing pocket 51.

(53) For the bayonet-like locking of the stay bolt 12 by rotating the locking plate 46 by 90°, it is provided that there are opposing key surfaces 53 on the outer circumference of the locking plate 46 which surfaces enable the stay bolt 12 to be inserted into the bearing pocket 51 and which, with the correctly assembled rotation of the closing plate 46, engage in undercuts in the area of the bearing pocket 51, so that, in case of a correctly assembled fixing of the stay bolt 12, the closing plate 46 prevents that the stay bolt 12 is pushed upward out of the bearing pocket 51.

(54) A spring-loaded rotary lock, which is shown in more detail in FIG. 6, is provided for locking the correctly assembled rotational position of the stay bolt 12. It is a transverse hole 66 in the bolt end 74 of the stay bolt 12, in which a compression spring 65 is mounted, on which a locking ball 64 acts, which engages in an assigned locking recess 75 in the manner of a spring-loaded index ball and secures the stay bolt 12 against rotating out of its correct rotational position.

(55) Instead of a rotary lock of the rotating bolt with a spring-loaded locking ball, other rotational locks can of course also be used, such as, for example, a key or a threaded guide pin which engages in an assigned recess in the stay bolt and secures it against rotation.

(56) In the embodiment according to FIGS. 6, 6a, 6b, it is advantageous if the disc spring 50 or a disc spring assembly now engages beneath the stay bolt, which is held non-rotatably in its displacement position, and due to this special arrangement, the locking element 10 can be used to provide the desired displacement in the arrow directions 38, 40.

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

(58) Another feature of the invention is that instead of an annular groove which overall weakens the cross-section of such a stay bolt, a single-sided hollow recess 39 is provided, which is associated with the advantage that the round material cross-section of the bolt end 74 is only slightly weakened by the single-sided hollow recess 39 according to FIG. 6b. This means that the stay bolt 12 can also transmit higher loads than in the prior art. According to FIG. 6, the hollow recess 39 is shaped as a circular section area and, according to FIG. 6a, consists of two angularly intersecting surfaces, so that the hollow recess 39 forms a circular recess at an angle in the transverse direction to the longitudinal extension of the bolt end 74.

(59) The stay bolt 12, with its bolt end 74 (see FIG. 6b), which is not weakened in cross section, forms an enlarged bearing surface (see FIG. 11) of this bolt end 74 at the guide part 58, as shown in FIG. 11.

(60) Accordingly, the stay bolt 12 is guided over a greater axial length in the direction of displacement, which is associated with increased stability against tilting, as could not be achieved with threaded screw connections according to the prior art.

(61) According to FIG. 6b, a further advantage results from the fact that the hollow recess 39, which is open on one side, provides an enlarged load-transmitting surface for the engagement of the clamping shaft 9.

(62) A locking element 10 with a clamping shaft 9 molded thereon can be seen in FIG. 6c. The hollow recess 39 of the stay bolt 12 engages in the wedge recess 19 of the clamping shaft 9 in a non-positive and positive manner. The wedge recess 19 is followed by a release, so that a first clamping action is effected during the rotation of the clamping shaft 9 by the engagement thereof into the release 36 in the wedge-shaped and eccentric hollow recess 39 at the bolt end 74 of the stay bolt 12. With increasing further rotation of the clamping shaft 9, the release 36 transitions into the wedge recess 19, via which the preliminary clamping force is then increased many times over in order to achieve the final clamping force. The bolt end 74 of the stay bolt 12 is preloaded with great force against the spring force of the disc spring 50 in the direction of its longitudinal extension.

(63) It is advantageous if the clamping shaft 9 is situated in a clamping shaft hole 73 which is formed eccentrically in relation to the center axis of the hollow recess 39. This is shown in FIG. 6.

(64) Upon rotation of the clamping shaft 9 in the counterclockwise direction according to FIG. 6, the stay bolt 12 is thus pulled down in the arrow direction 55 against the force of the disc spring 50, wherein the displacement path 63 in the area of the guide recess 60 can be exploited.

(65) As previously shown, the guide part 58 has an axially extending, sleeve-like guide projection 61 that is open on one side, on the inside of which the bearing surface 62 is arranged for bearing against the outer circumference of the bolt end 74 of the stay bolt 12.

(66) An elongated hole 67 is arranged in the body of the mounting rail 4, which hole enables the locking ball 64 and the compression spring 65 to be mounted.

(67) The elongated hole 67 is an extension of the hole. FIG. 6 shows that a bearing hole 52 is arranged in the mounting rail 4 as an extension of the guide part 58, in which bearing hole 52 the stay bolt 12 is rotatably and spring-loaded displaceably mounted. The stay bolt is only rotated during mounting. After mounting is complete, the stay bolt is secured against rotation by the spring-loaded locking ball 64 and can be displaced in a spring-loaded manner only in the axial direction of its bolt end 74.

(68) Thus, the present invention has the advantage that with a greatly reduced structural height of the one rail 4, a special type of attachment of a stay bolt 12 is now provided, which is no longer formed as a threaded screw connection, but as a spring-loaded bayonet screw connection, which represents a significant advantage compared to the prior art.

(69) The illustrated spring-loaded bayonet connection represents a particularly elegant mounting of the stay bolt 12 because said stay bolt 12 engages assigned undercuts in the area of the mounting rail by means of its closing plate 46 and after mounting is complete, said stay bolt is secured against rotation and can be displaced in a spring-loaded manner only in the axial direction (in the direction of its longitudinal extension).

(70) In another embodiment, not illustrated graphically, it can be provided that, instead of a bayonet screw connection for the securing of the axial position of the stay bolt 12, a simple attachment plate is present that is arranged on the mounting rail side and rotatable on one side and which covers, in the working position, the head of the stay bolt upwardly in the bearing pocket 51 and which is attached with the aid of an attachment screw on the mounting rail and is rotatable parallel to the surface of the mounting rail 4. In the mounting position, the attachment plate is pivoted away from the bearing pocket 51 so that the stay bolt can be introduced into the bearing pocket 52. In the working position, the attachment plate is pivoted over the bearing pocket 51 and covers the head of the stay bolt 12, namely its closing plate 46, towards the top. This type of attachment also secures the stay bolt 12 from falling out of the guide part 58 upwards.

(71) With this solution, the rotate and screw attachment of the stay bolt 12 is omitted. Rather, the stay bolt is directly inserted in the bearing hole 52 in the direction of its longitudinal extension and fixed with the aid of the pivotable attachment plate situated above.

(72) In principle, the bayonet screw connection can also be completely omitted, so that the stay bolt 12 is only inserted into the bearing hole 52 on the guide part 58 in the direction of its longitudinal extension and the previously described rotary lock would then also provide an axial displacement lock for the stay bolt 12. There is therefore no need for a bayonet screw connection to secure against falling out and also no rotatably mounted attachment plate.

(73) The mounted telescopic sight 1 then secures the stay bolt 12 with its underside against falling out in the direction of its longitudinal extension upwards, because suitable bearing surfaces are provided on the underside of the telescopic sight.

(74) A groove and spring guide or a dovetail guide arranged in the longitudinal direction of the stay bolt 12 at or in the bearing pocket 51 and/or the guide part 58 can be provided for the stay bolt 12 in the bearing pocket 51 and/or in the guide part 58 as a longitudinal guide secured against rotation.

(75) The invention is therefore not dependent on a bayonet screw connection of the stay bolt to secure it against falling out, but prefers such a configuration because it is a particularly elegant and simple attachment of such a stay bolt 12.
