DETAILED DESCRIPTION

(7) In the figures, one possible embodiment of a sighting device according to the invention for firearms, in particular for handguns, is shown and is generally identified by the reference signs 1 in different views and with two design variants which differ in a detail.

(8) The sighting device 1 contains three essential components, namely a base 2, a first sighting lever arm 3, and a second sighting lever arm 4. The first sighting lever arm 3 is mounted on the base 2 by means of a pin 8, the longitudinal axis of which defines a first pivot axis. For this purpose, holes 24 are provided in the base 2, through which the pin 8 is guided and furthermore through a hole (not shown in greater detail here) in the first sighting lever arm 3, which aligns with the holes 24.

(9) The second sighting lever arm 4 is pivotably fixed via a pin 19, the longitudinal axis of which defines a second pivot axis, on the first sighting lever arm 4. A rear sight device 5 is arranged on the second sighting lever arm 14 on a longitudinal end opposite to the pin 19. This rear sight device contains a rear sight part receptacle (not shown in greater detail here), in which different rear sight parts can be arranged and fastened, which can have different rear sight geometries and/or rear sights of different designs. In the illustrations in the figures, a semicircular rear sight known per se is arranged in the rear sight device 5. The rear sight device 5 is configured so it is displaceable to adjust a lateral point of impact of the firearm equipped with the sighting device 1 according to the invention in a direction transverse, in particular perpendicular to a longitudinal direction of the arrangement made up of first sighting lever arm 3 and second sighting lever arm 4. A positioning mechanism to be operated via a set screw 16 is provided for adjusting the transverse position of the rear sight device 5.

(10) Two positioning devices are provided for adjusting the point of impact of a firearm equipped with the sighting device 1 according to the invention, in particular a handgun, such as a pistol or a revolver. Using a first positioning device 6, the pivot position of the first sighting lever arm 3 is adjusted and additionally also a pivot position of the second sighting lever arm 4 connected to the first sighting lever arm 3 and thus the vertical position of the rear sight device 5. A second positioning device 7 enables a separate adjustment of the pivot position of the second sighting lever arm 4 relative to the first sighting lever arm 3 and the base 2, to thus also achieve a vertical adjustment of the rear sight device 5.

(11) The two positioning devices, first positioning device 6 and second positioning device 7, are used for different adjustment options, as will be explained in greater detail hereinafter. The first positioning device 6 is thus designed for the purpose of performing a plurality of presets for the elevation of impact setting of the sighting device 1 and being able to change easily between these presets. The second positioning device 7 is used to adapt a sighting setting performed on the basis of a selected preset to special features occurring in the specific usage situation of the firearm equipped with the sighting device 1, for example, special light conditions or the like, and can be referred to as a daily sighting setting. The special feature of the sighting device 1 according to the invention is in the design of the first positioning device 6 here, which is explained in greater detail hereinafter with reference to the figures and elements shown therein.

(12) However, it is also to be noted here beforehand that the sighting device 1, as shown in FIGS. 1, 2, 3, and 5, has a so-called Picatinny rail formed on the base 2, which is a standardized attachment device for attaching accessory parts to firearms. The typical components of the Picatinny rail can be seen, namely the lateral wedge grooves or dovetail grooves 9, and the transverse grooves 10 guided transversely to the wedge grooves 9 and defined in the spacing by the standard. The special feature in the sighting device 1 according to the invention and the Picatinny rail embodied with it is that the Picatinny rail extends in a region beyond the first sighting lever arm 3 and the second sighting lever arm 4, i.e., extends almost up to the end of the base 2, on which the rear sight device 5 is arranged. This also enables, due to the flat design obtained by the construction shown of the sighting device 1, accessory parts, for example, a light spot sight, to be able to be placed on the sighting device 1 and fixed there with the aid of the Picatinny rail, without the sighting device 1 having to be removed from the firearm. In particular in conjunction with a handgun, such an accessory part can be arranged mounted on the firearm very far in the direction of the rear side opposite to the muzzle, which is a clear advantage for the usage comfort and the shooting performance. The sighting device 1 according to the invention can also be implemented without such a Picatinny rail, however, as shown in FIG. 4, for example. In all figures, the sighting device 1 is shown as an independent part, which can be fixed on a firearm via holes 17 in the base 2 by means of screws introduced therein, which are screwed into corresponding threaded holes in a counterpart on the firearm. However, it is just as possible in the scope of the invention to design the sighting device 1 according to the invention as a fixed and integral component of a firearm, wherein then in particular the base 2 is formed integrated in a component of the firearm.

(13) The special feature of the first positioning device 6, using which the plurality of preset vertical points of impact of the sighting device 1 or the firearm equipped with it can be adjusted and selected comfortably, will be explained in greater detail hereinafter.

(14) The core of the first positioning device 6 is a rotating positioning element 20, which is formed disk-shaped in the embodiment shown and is arranged between the base 2, more precisely the bottom 30 of the base 2, and the first sighting lever arm 3. The rotating positioning element 20 is arranged in the first sighting device 1 rotatably around a rotational axis extending perpendicularly to the plane of the bottom 30 and also perpendicularly to the first pivot axis, wherein an actuating element 11 is provided, which is connected here in a formfitting manner to the rotating positioning element 20 using a hexagon extension and via which the rotating positioning element 20 can be pivoted around the rotational axis. The hexagon extension protrudes here through a passage 27 in the first sighting lever arm 3. A lock ring (not provided with a reference sign) secures the actuating element 11 axially on the rotating positioning element 20. The actuating element 11 is arranged in a depression 25 in the first sighting lever arm, which secures the actuating element 11, in particular from possible impacts or unintentional pivoting.

(15) The rotating positioning element 20 has a total of six threaded holes 21 arranged circularly and with uniform angle distribution around the rotational axis, which protrude through the rotating positioning element 20. Grub screws 13, which form of alignment elements, are screwed into the threaded holes 21. Only one grub screw 13 is shown in each of the figures here, to make the figures more comprehensible. In general, grub screws 13 are screwed in each case into all six threaded holes 21. In principle, however, threaded holes 21 can also remain free without deviating from the invention. The invention thus does not presume equipping all threaded holes 21 with grub screws 13.

(16) A buttress element 18, which is elevated in relation to the surroundings and which has a frontal depression 29 on an upper end, is formed on the bottom 30 of the base 2. This depression 29 is formed complementary to the shape of a positioning tip 28 of the grub screws 13, so that these positioning tips 28 of the grub screws 13 can engage in a formfitting manner in the depression 29. The buttress element 18 is arranged at a distance from the rotational axis which corresponds to the distance of the threaded holes 21 on the rotating positioning element 20 from the rotational axis. Accordingly, the threaded holes 21 can each be brought into a flush alignment with the buttress element 18, so that the grub screw 13 arranged in the aligned threaded hole 21 engages with its positioning tip 28 in the depression 28 of the buttress element 18. A ring groove 31 is introduced into the bottom 30 of the base 2 extending around the rotational axis in a radius corresponding to the distance of the threaded holes 21 from the rotational axis, which is used to accommodate the grub screws 13 which are not flush with the buttress element 18 and placed with their positioning tip 28 in the depression 29, more precisely their positioning tips 28, so that they are without contact with the bottom 30 of the base 2.

(17) Two compression springs 22 are fixed on cylindrical spring seats 23 on the bottom 30 of the base 2 and press against a short lever arm of the first sighting lever arm 3, which is on the side of the pin 8 opposite to the positioning device 7 and thus the first pivot axis. These compression springs 22 press the arrangement made up of first sighting lever arm 3 and second sighting lever arm 4 in a pivot direction toward the base 2 into a basic position.

(18) To perform a sighting vertical adjustment via the presets using the total of six grub screws 13 arranged in the threaded holes 21, firstly one of the grub screws 13 is placed with its positioning tip 28 in the depression 29 of the buttress element 18 by rotating the rotating positioning element 20 by means of the actuating element 11 around the rotational axis so that the grub screw 13 is positioned in appropriate correspondence with the buttress element 18. In this position, the grub screw 13 can be reached using a tool, for example, a hex socket, through a recess 12 in the actuating element 11 and through an opening 26 accessible through the recess 12, which extends through the first sighting lever arm 3. By screwing the grub screw 13 into or out of the threaded hole 21, the distance of the rotating positioning element 20 to the base 2, more precisely to the bottom 30 of the base 2, is changed and thus the pivot angle of the first sighting lever arm 3 and also the second sighting lever arm 4 fastened thereon is changed. A vertical adjustment of the rear sight device 5 is thus obtained. If the desired elevation of impact is achieved, which is verified by corresponding test shots, by pivoting the rotating positioning element 20, which is achieved by rotating the actuating element 11, a further grub screw 13 in another threaded hole 21 is placed on the buttress element 18 and using corresponding adjustment of the screw position of this grub screw 13, a different sighting basic setting is set with regard to the elevation of impact, for example, for a differing shooting distance.

(19) There is now the option of performing a total of six different sighting basic settings, in that the six grub screws 13 screwed into the threaded holes 21 are each placed on the buttress element 18 and then adjusted in their height by corresponding screwing. Via the counter pressure exerted by the compression springs 22, the respective grub screw 13 is pressed with its positioning tip 28 into the depression 29 of the of the buttress element 18, so that the vertical setting of the rear sight device 5, which is obtained by the pivot position of the first sighting lever arm 3 with the second sighting lever arm 4 fastened thereon, is maintained.

(20) The user of the sighting device 1 or the firearm provided with it can now select the matching sighting basic setting in different shooting situations, for example, in different competitive disciplines, by pivoting the actuating element 11 and thus adjusting the rotating positioning element 20 such that the associated grub screw 13 rests on the buttress element 18 and the corresponding sighting basic setting is selected. In order that the user can more easily identify the sighting basic setting performed by him in the first positioning device 6, corresponding markings are advantageously arranged on the actuating element 11, for example, numbers from 1 to 6 applied in the region of the recesses 12.

(21) To pivot the rotating positioning element 20 by means of the actuating element 11, the user only has to slightly raise the first sighting lever arm 3 (possibly together with the second sighting lever arm 4), i.e., pivot it away from the bottom 30 of the base 2, and can then rotate the actuating element 11 and thus align it, such that the desired grub screw 13 rests with its positioning tip 28 in the depression 29 of the buttress element 18. The circumferential recesses 12 on the actuating element 11 help to recognize this position in this case. If the grub screw 13 is aligned with the buttress element 18, the user can lower the first sighting lever arm 3 again, wherein the compression springs 22 ensure a corresponding counter pressure which presses the grub screw 13 with its positioning tip 28 into the depression 29 of the buttress element 18 and fixes it in a formfitting manner therein, as it were holds it locked. This thus prevents the selected position of the first positioning device from being able to be changed unintentionally.

(22) To additionally give the shooter the option of performing a daily setting of the sighting device 1 with its elevation of impact for a selected basic setting, the second positioning device 7 is provided. It includes a set screw 14, which is fixed immovably on the second sighting lever arm 4 in the direction of its longitudinal axis and is screwed with its screw thread into a threaded hole in the first sighting lever arm 3. By further screwing the set screw 14 into or out of the thread in the first sighting lever arm, a pivot angle of the second sighting lever arm 4 can thus be adjusted in relation to the first sighting lever arm 3 and therefore also in relation to the base. The pin 19, as already mentioned, defines the second pivot axis, around which the second sighting lever arm is pivoted in relation to the first sighting lever arm 3 by pivoting the set screw 14. Thus, with a preset selected once, as is set using the first positioning device 6, a further vertical adjustment of the rear sight device 5 can be performed and thus a point of impact correction can be carried out. To give a scale for the user here and to enable easy comprehension of the daily sighting setting, a corresponding marking 15 is provided on the set screw 14. A basic position is indicated here by a “0”, positioning directions for raising or lowering the point of impact are identified with arrows having the signs “+” and “−”. A tooth-like knurling of the edge of the head of the set screw 14 and a point marking 32 on the second sighting lever arm 4 facilitate the orientation of the rotational positions and thus a recognition of the adjustment by means of the second positioning device 7. The second sighting lever arm 4 is pre-tensioned in relation to the first sighting lever arm 3 in a pivot direction facing away from the base 2 via at least one compression spring 33 arranged between the first sighting lever arm 3 and the second sighting lever arm 4. This pre-tension holds the set screw 14 in the selected screw position and prevents unintentional adjustment of the second positioning device 7.

(23) The option is thus provided by the sighting device 1 according to the invention of performing a plurality of presets of the elevation of impact of a firearm equipped with the sighting device 1 and leaving them fixed and simply selecting them, for example, adapted to different competitive disciplines having different target distances or also adapted to different ammunition used, for example, having different charges. A daily sighting setting can also be performed via the second positioning device 7 to be able to react to special features at the time of shooting, for example, on the competition day, for example, particular light conditions, or the like. It is not necessary here to change the sighting basic setting(s).

(24) The sighting device 1 according to the invention is very functional and can exercise further functions by way of the possible additional designs, for example, the Picatinny rail. The sighting device 1 according to the invention is distinguished by a flat design and compact construction, so that in particular it can also be integrated in handguns, even those of filigree design, or attached thereon, without impairing the use of these firearms or also interfering with the design.
