  • the front sight carrier element In the moment-transmitting connection, the front sight carrier element can be folded up or down, but cannot be moved sideways. In the non-torque-transmitting connection, on the other hand, the front sight carrier element can be moved laterally. A rotational movement of the axially fixed axis transmits this rotational movement to the thread of the front sight carrier element, causing it to move laterally.
  • the profile is arranged on its outer circumference in the circumferential direction of the axle body.
  • the profile which is arranged in the circumferential direction and extends in particular over a specific axial region of the axle, facilitates the engagement of the first geometry and in particular brings about a stable torque-transmittable connection.
  • the profile is formed by at least two, preferably four, recesses in the axle body that extend in the axial direction of the axle. It is preferred if a respective recess forms a surface and a respective face is offset 90° from an adjacent face. It has proven to be advantageous that adjacent surfaces do not touch directly, but rather that adjacent recesses in the circumferential direction are separated by lateral surface sections of the axle body. The outer surface sections form, as it were, rounded corners.
  • a profile can preferably be provided that resembles a square in its cross section and provides a stable and secure transmission of a moment, since it is ensured that the moment is transmitted over the surface and not over the corner. This also increases the service life.
  • the rounded corners also make it easier to engage the first geometry of the keyhole-like opening of the adjustment element to produce the torque-transmittable connection.
  • the profile borders on threaded sections of the axle body in both axial directions of the axle, so that, in other words, the profile is arranged axially between two threaded sections, namely between a first and a second threaded section.
  • the thread sections are provided in particular to enter into a connection with the thread or threads of the front sight carrier element in order to transmit a rotational movement of the axis to the front sight carrier element.
  • the two threaded sections are formed into a single threaded section, i.e. the lateral surface sections form a third profile section that connects the first profile section to the second profile section, so that a continuous thread is formed.

  • the axle can have a circumferential groove on one of its two ends for receiving a locking washer or a bore for receiving a locking pin.
  • the axle has a screw head at its other of the two ends for attaching a tool for the lateral adjustment of the front sight carrier element.

  • a gripping surface at its other of the two ends, in particular a knurled or cord knob for tool-free lateral adjustment of the front sight carrier element.
  • This embodiment has proven to be particularly advantageous because the lateral adjustment can take place more quickly and without tools, which is particularly advantageous in a combat situation.
  • the lateral adjustment can be made by pulling the front sight out of the detent against the spring force and turning the knurled or cord knob with the right hand.
  • an adjustment element for an adjustable sighting device, in particular a folding, height-adjustable and laterally adjustable sighting device.
  • the adjustment element according to the invention has a first section which extends in a longitudinal direction and a planar second section which is connected to the first section.
  • the first section also has a means for the detachable connection to a sighting comm, a thread arranged on an axial end of the first section preferably being provided as a means for the detachable connection.
  • the second section has a keyhole-like opening for the passage of an axle supporting a front sight carrier element, which is designed on the one hand to create a moment-transmittable connection with the axle by means of a first geometry and on the other hand is designed to use a second geometry to prevent the torque-transmittable connection with this axle, ie to establish a non-torque-transmissible connection with this axle.
  • An adjustment element is thus provided which, as part of the sighting device assembly, serves as a locking device for preferably three adjustment options, namely folding up and down, lateral adjustment and height adjustment.
  • the keyhole-like opening is particularly important for the lateral adjustment, since the keyhole-like opening allows the adjustment element to be moved relative to the axis, in particular perpendicular to the axis, in order to move the adjustment element either "in engagement (engaged position) with the axis or "out of engagement”. (Release position) with the axis.For folding up and down, and for height adjustment, the keyhole-like opening is not required but is advantageous.
  • the engagement position corresponds to that position of the adjustment element relative to the axis in which the torque-transmittable connection is present.
  • a front sight carrier element that is folded open and a front sight that is folded down corresponds, for example, to this position when the front sight is in the latched position. In this position, lateral adjustment is not possible, since the keyhole geometry virtually fixes the profiled surface of the axle or, to put it another way, would block a rotary movement of the axle.
  • torque-transmittable connection means that the adjusting element assumes a position or position in relation to the axis in which a torque can be transmitted. This position serves in particular to prevent an unwanted lateral displacement of the front sight carrier element and thus of the front sight. If an attempt were made in this position to rotate the axle about its own axis of rotation, the keyhole-like opening of the adjustment element would exert a counter-torque and prevent lateral adjustment.
  • the adjustment element By pulling the front sight against the spring force, the adjustment element is transferred to the release position. In this position, a lateral adjustment of the front sight carrier element (and thus also of the adjustment element) is permitted because the non-torque-transmittable connection is now between the axle and the adjustment element exists and therefore no torque can be transmitted.
  • the axially fixed axis can now be rotated manually or using a tool. This rotary movement is transmitted via the threaded coupling to the front sight carrier, which can now be moved laterally, i.e. in the axial direction of the axle.
  • the circular section merges into a straight section, which in turn merges into the quadrangular section after a certain axial extent.
  • the straight section connecting the two geometries is preferably at least partially parallel to the axis of rotation of the cylindrical body of the first section.

  • the square section can have rounded corners.
  • a second circular section can also be provided.
  • the end of the second section axially opposite the first section has rounded corners with a first radius and a second radius that differs from the first radius.
  • Rounded corners with radii of different sizes allow optimal interaction between the adjustment element and the holding device.
  • Rounded corners allow the adjustment element to be brought into contact with a baffle of the holding device and to be allowed to slide over the baffle, particularly during a folding and folding movement of the grain carrier. The contact occurs during the folding movement, in particular against the force of the spring element, while the "let it slip” occurs with the force of the spring element.

  • the adjustment element is arranged with and against the spring force between two positions relative to the axis within the front sight carrier element, so that it can be moved inside the front sight carrier element, so that the keyhole-like opening prevents lateral adjustment of the front sight carrier element along the axis in an engagement position with the axis and allows lateral adjustment of the front sight carrier element in a release position.
  • the axle can enter into both a torque-transmitting connection and a non-torque-transmitting connection with the front sight carrier element.

  • the sections s2 and s3 are provided with the thread 38a, 38b and are - in a central position of the front sight carrier element - in engagement with the corresponding threaded bore 27, 29. If the front sight carrier element 20 is rotated to the left or right, starting from the central position, it can the threaded portion 38c can also be brought into engagement with the threaded bores 27 and 29, respectively.
  • section s1 is smaller than the diameter of section s4. Since the bores of the holding device 50 correspond to these diameters, these are also of different sizes. The result of this is that the axle 30 can always only be inserted into the holding device 50 from the same side, in this case from the right-hand side.
  • the diameters of sections s2, s3 and s4 are essentially the same size. Also clearly visible is the flattened recess 33 axially between the sections s2 and s3.
  • FIG 4 shows an adjustment element 40 in a preferred embodiment for an adjustable sighting device.
  • the adjustment element 40 is shown in an unfolded position and can be pivoted through an angle ⁇ and thus folded down.

  • the thickness t of the second section 42 corresponds approximately to the diameter of the cylindrical section 41 Section 41 guided spring element 75 is supported or with which the spring element 75 can be brought into contact.
  • the adjustment element roughly represents the geometry of a key blank.
  • the second section 42 has a keyhole-like opening 44 through which the axis 3 can be performed to the grain carrier 20 from 2 to store.
  • the keyhole-like opening 44 is formed as a through hole and is essentially formed by two geometric shapes, namely a circular portion 45 having a straight portion 45a and a square portion 46 with rounded corners.
  • the circle section 45 with the diameter dl is arranged above the square 46 with the diameter d2, the diameter d1 being smaller than the diameter d2.
  • the circular section 45 merges into a straight section 45a with the same diameter d1, which in turn merges into the quadrangular section 46 after a certain axial extension downwards.
  • the straight one Section 45a connecting the two geometries is at least partially parallel to the axis of rotation of the cylindrical body of the first section 41.
  • the straight section 45a acts in the torque-transmitting position like a "square wrench” gripping a "square nut”.

  • the through hole 44 is functionally suitable for establishing a moment-transmitting connection with the axle 30 by means of the geometry 45 in the form of a segment of a circle and for releasing this connection by means of the quadrangular geometry 46 in order to allow a lateral adjustment of the grain carrier 20 .
  • the adjustment element 40 can be moved perpendicularly to the axis 30 .
  • either the circular section 45, 45a or the square section 46 with the profile 32 of the axle 30 can be brought into an "engaged position" or a "release position".
  • the diameter d1 is selected such that it is minimally smaller than the diameter of the axle body 31, so that the straight sections 45a can optimally encompass the straight surface profile 32, 33.
  • the adjusting element 40 has rounded corners with a first radius r1 and a second radius r2 different from the first radius r1 at its lower end.
  • first radius r1 In an unfolded position, the side with the small radius r1 faces the muzzle, i.e. forwards, while the large radius r2 faces backwards.

  • the frame 52a forms a depression with the base 52, into which a part of the adjusting element 40 protrudes during a pivoting movement.
  • On the frame are two opposite each other and arms 53, 54 arranged essentially perpendicularly to the surface of the base 52 for receiving the axis 30 for the pivotable mounting of the front sight carrier element 20.
  • the adjustment element 40 comes into contact with the base 52 and with a control link 51 fastened to the base 52 or to the frame 52a. Due to the spring-loaded arrangement of the adjustment element 40, however, it can pass the base 52 and the control link 51 against the force of the spring element 75. In the unfolded position, the adjustment element 40 is pressed into the base 52 by means of the spring element 75 .
  • the adjustment element 40 can be locked both in an open and in a folded-down position of the front sight carrier element 20 .
  • the contact surface 51 is arranged at an angle to the base 52 and parallel to the axis 30 and has the geometry of a ramp whose sloping side faces the adjustment element 40 .

  • the holding device 50 also has a fixed stop 55 on which the front sight carrier element 20 is supported in a folded-down position.
  • an adjustable sighting device 70 in a preferred embodiment in the form of a folding, height- and side-adjustable sighting device, comprising a front sight carrier element 20, which is pivotably mounted on a holding device 50 by means of an axis 30, the front sight carrier element 20 being attached to a spring element (not shown ) mounted and detachably connected to a visor 10 adjustment element 40, which comprises a keyhole-like opening (not shown), through which the axis 30 is passed.
  • the adjusting element 20 is arranged with and against the spring force between two positions relative to the axis 30 movable within the front sight support element 20, so that the keyhole-like opening in an engagement position with the axis is a lateral Prevents adjustment of the front sight support element 20 along the axis 30 and allows the lateral adjustment of the front sight support element 20 in a release position.
  • the sighting device 70 comprises the adjustment element 40 4 , The inside of the sighting grain carrier element 20 after 2 stored and with the front sight 10 after 1 is detachably connected.

  • the axis 30 is fixed axially on the holding device 50 by means of a locking washer 35a.
  • the holding device 50 is part of the gas outlet 60.
  • the gas outlet 60 is secured by a rivet 61 on the barrel 80 of the weapon.
  • FIG 7 shows the sighting device 70 of FIG 6 in two sectional views in an unfolded or pivoted position.
  • the front sight 10 or front sight carrier 20 can be swiveled in, ie folded down, to the rear about a swivel axis designed as an adjustment axis.
  • FIG. 12 also shows how a spring element 75 designed as a compression spring is supported on the contact surfaces 24a, 42a of the front sight carrier element 20 and the adjustment element 40, respectively. Since the front sight carrier element 20 is mounted on the axis 30, a force F is always exerted on the second section 42 in order to hold the front sight 10 in its latched position or locked position. The sighting device 70 is in the unfolded position, the force F therefore acts downwards and presses the first geometry 45, 45a of the opening 44 into the profile 32 of the axle 30.
  • FIG. 8 shows a sighting device 70 with an alternative axis 30, in which, instead of a screw head, a knurled knob 37 for tool-free lateral adjustment of the Front sight carrier element 20 is provided. Otherwise, the structure corresponds to that of 6 or 7.
  • the Figures 9 to 12 show the swiveling process from the unfolded position to the folded position.
  • 9 represents the starting point of the folding process at a point in time t1.
  • the compression spring 75 presses the adjusting element 40 downwards.
  • the adjustment element 40 in turn is supported on the horizontal surface of the base 52 of the holding device 50 .
  • the adjustment element 40 is supported on the inclined contact surface 51 of the holding device 50 via the small corner radius r1 on the right-hand side.
  • this prevents the front sight carrier element 20 from folding over when the shot is fired and, on the other hand, compensation is provided so that the front sight carrier element 20 and thus in particular the front sight 10 do not wobble.
  • the adjustment path as the pivoting movement of the front sight carrier element 20 is limited to the rear by a fixed stop 55 .
  • the 10 shows two snapshots at time t2 and at the subsequent time t3.
  • the small radius r1 slides over the sloping contact surface 51 of the holding device 50 when the adjustment element 40 is folded over.
  • the adjustment element 40 is pressed upwards against the spring force F (represented by straight arrows).
  • the front sight carrier element 20 is further folded down.
  • the larger radius r2 on the left side of the adjustment element 40 comes into contact with the base 52 of the holding device 50, while the smaller radius r1 is disengaged, i.e. no longer has contact with the ramp 51.
  • the adjusting element 40 is still slightly raised against the spring force. Due to the keyhole-like geometry of the through-hole 44, the axis 30 for lateral adjustment of the front sight 10 is also rotated via the profile 32 attached to the axis 30. By taking the axis 30 with you when folding down or unfolding the front sight 10, it is ensured that its position does not shift laterally.
  • FIG 11 shows the sighting device 70 in the folded-down position at a fourth point in time t4.
  • the front sight support element 20 is supported in the folded-down position horizontally on the gas take-off 60 connected to the holding device 50 via the fixed stop 55.
  • the large radius r2 of the adjustment element 40 engages over the ramp 51 of the holding device 50.
  • the visor 70 or the front sight carrier element 20 can be opened and folded down without having to "put on” the front sight 10 .
  • the radius R2 and the ramp 51 cooperate as a detent in the folded position such that the front sight holder 20 is held in this locked position (down) during firing. With a little more effort, the front sight carrier element 20 can be released from this locking position and swung open without additional pulling of the front sight 10 . This means that opening takes place in the reverse order of folding down.
  • second section 42 of adjustment element 40 can be brought at least partially into contact with chicane 51 of holding device 50, so that adjustment element 40 can be moved counter to the force of spring element 75.
  • movement of adjusting element 40 against the force of spring element 75 is only permitted in such a way that the moment-transmitting connection between axis 30 and front sight carrier element 20 is always maintained during the pivoting movement.
  • the adjusting element 40 comes in the unfolded state ( 1 ) in contact with the ground 52.
  • the locking function is essentially taken over by the ramp 51 .
  • the ramp 51 also limits the downward path of the adjustment element 40 .
  • FIGS 12 to 14 show the process of lateral adjustment of front sight carrier element 20 or front sight 10.
  • 12 show the Sighting device 70 in the from 9 known initial position: the front sight 10 is in the middle position and in the open position.
  • the sighting compass 10 can be released.
  • the front sight 10 with the adjustment element 40 is pressed downwards by the spring force.
  • the profile 32 (square nut) of the axle 30 is brought into engagement with the first geometry 45, 45a (square spanner) of the keyhole-like through-opening 44 of the adjusting element 40 and thus locked.
  • the lateral adjustment of the front sight carrier element 20 in the position of the non-torque-transmittable connection can be effected by rotating the axle 30, which is axially fixed to the holding device 50, with the rotary movement being achieved via the threaded coupling 27, 29 or 38a, 38b of the axle 30 with the front sight carrier element 20 of the axis 30 is transmitted to the front sight carrier element 20 in such a way that it is moved laterally.
  • the 15 and 16 show the process of adjusting the height of the sighting device 70.
  • the front sight 10 In the starting position at time t1, the front sight 10 is locked by the groove in the front sight holder 20. To adjust the height, the front sight 10 must be pulled upwards with the adjusting element 40 against the force of the compression spring 75 . In the upper position, the front sight 10 can now be rotated, as shown at a point in time t8. The front sight height is adjusted via the threads 12, 43 between the front sight 10 and the adjusting element 40 by manually rotating the front sight around its own axis. If the front sight 10 is then released at time t9, it is locked in the groove of the front sight holder 20 by the spring return, as in 16 shown at time t10. The points in time t9 and t10 show the front sight 10 in the upper and lower end position.
  • the front sight 10 can therefore be transferred by means of a pulling movement against the spring force from its detent position, in which a rotational movement of the front sight 10 is prevented, into a twisted position, in which a twisting of the front sight 10 for height adjustment is permitted.
  • Figure 13 shows a further representation of the operation of the keyhole-like opening 44 with the profile 32 of the axis 30 in a perspective with part of the sighting device 70 cut away.
  • the unfolded position is shown on the left, as seen from 9 , 12 and 14 is known.
  • the compression spring 75 presses the adjusting element 40 downwards, as a result of which the first geometry 45, 45a is brought into engagement with the profile 32 of the axle 30.
  • the second section 42 is also pressed into the base 52 of the holding device 50 . It is easy to see how the straight sections 45a bear parallel and tightly against the flat sections 32 or enclose them, like a square wrench encloses a square nut.
  • the raised position is shown on the right, as already seen 13 and 15 is known.
  • the front sight 10 pulls the adjustment element 40 up against the force of the spring 75, as a result of which the axis 30 is now surrounded by the second geometry.
  • the second geometry 46 has a larger diameter and allows the fixed axis 30 to rotate about its own axis of rotation.
  • FIG 18 shows a side view of a handgun 1 with the sighting device 70 described above.
  • the handgun 1 comprises a rear sight device with a rear sight 80 that is complementary to the sighting device. Sighting device 70 and rear sight device 80 are shown in their unfolded state.
