Description

[0001] This application claims priority to European Patent Application No. 25 185 440.2 filed on Jun. 26, 2025 and German Patent Application No. 10 2024 120 574.1 filed on Jul. 19, 2024, the disclosures of which are hereby incorporated by reference.TECHNICAL FIELD

[0002] The invention relates to a mounting device for fastening an auxiliary part, in particular a sighting unit, to a handgun. Furthermore, the invention relates to a handgun with a mounting device according to the invention.SUMMARY

[0003] Mounting devices of this type are used to fasten auxiliary parts, for example sighting units, lighting units or similar, to a weapon. Firearms, especially short guns such as handguns, have a shorter barrel compared to long guns and are used in a variety of applications in the leisure sector. Handguns are also of great importance to the police and armed forces when it comes to averting danger. To take aim at a target, known handguns are usually equipped with a sight consisting of rear sight and front sight. When aiming at the target, the rear sight and the front sight must be brought into alignment in order to hit the selected target. This type of target recognition requires a very high level of training, as the alignment of the rear sight and the front sight can be highly inaccurate due to the short barrel of handguns.

[0004] In order to enhance target recognition while aiming at targets, it is known to mount a sighting unit on the firearm, which replaces iron sights having rear and front sights. These additional sighting units, which are to be fastened to the firearm, may, for example, be a red dot sight, a prism sight or a reflex sight, which are usually also used on long guns. Generic mounting devices, often referred to as mounts, are used to fasten the sighting unit to the firearm. These devices can be fixed to a mounting rail on the barrel end of the grip frame of the firearm and at the same time allow the fastening of a sighting unit available as an auxiliary part. As a result, the device can be used to fasten a sighting unit of choice to the firearm. The known devices for fastening a sighting unit to a firearm have the disadvantage that they are complex to manufacture and have to be adapted to each individual firearm.

[0005] In addition, it is preferable to connect the auxiliary part to the weapon at a single fastening point, especially in the case of auxiliary parts of short design, such as red dot sights having a lens-optical or laser-optical design. This places particularly high demands on the precise alignment of the auxiliary part in relation to the barrel of the weapon. For this purpose, it is known from the prior art in possible embodiments that the auxiliary part and / or the base plate has a pivot pin which is used for pivot mounting with a locking mechanism of the auxiliary part on the weapon.

[0006] The mounting devices known from the state of the art have the common feature that they are mounted on a support plate already provided on the weapon, so that the weapon must already have structural features, such as a sufficiently large support plate, for mounting an auxiliary part. However, there is also a need to fasten auxiliary parts to weapons that have no support plate or no suitable support plate for fastening, but merely have a different type of interface, such as a recess. Furthermore, easy positioning as well as fixating and securing of the auxiliary part on the weapon should be enabled.

[0007] Background Based on this state of the art, it is the object of the present invention to propose a novel mounting device for fastening an auxiliary part to a handgun, which can be positioned, fixated and secured on the weapon easily and quickly. The mounting device is also intended to enable simple and rapid replacement of the auxiliary part.

[0008] The mounting device according to the invention serves to fasten an auxiliary part, in particular a sighting unit, to a handgun which has at least one ferromagnetic part, in particular a ferromagnetic slide, the mounting device comprising a base plate to which the auxiliary part can be fastened. Preferably, the base plate can be attached to a contact surface of the handgun, the contact surface being formed in the area of the slide of the handgun, said area consisting of a ferromagnetic material. In the context of the invention, the contact surface refers to the area of the handgun, in particular the area of the slide of the handgun, against which the mounting device comes to rest. According to the invention, a base plate has at least one magnet unit, which is arranged either directly or indirectly in the base plate and comprises at least one magnet. The base plate is provided with a surface facing away from the handgun for fastening the auxiliary part and a mounting surface facing toward the handgun. Said mounting surface is essentially complementary in shape and function to the associated contact surface on the weapon in such a way that, when the mounting device is fastened to the handgun, the mounting surface either partially rests against the contact surface or is positioned at a small distance opposite the same.

[0009] In other words, this means that the positioning and fastening of the mounting device on the handgun can initially be achieved by the magnetic force between the magnet unit of the mounting device and the ferromagnetic area of the weapon opposite said magnet unit. In addition, the positioning of the mounting device on the handgun can be further simplified by a positive fit of the base plate on the associated area of the contact surface of the handgun, for example an area of the slide, preferably an area above the grip frame or magazine. This alone results in a repeatable mounting and dismounting of the mounting device. For example, the slide and grip frame of the handgun are regularly made of ferromagnetic steel, which can interact with the at least one magnet of the magnet unit for fastening the mounting device to the handgun.

[0010] The final fixation of the device to the handgun, both to prevent accidental detachment and to absorb the recoil forces acting during firing, is effected by the locking unit according to the basic concept of the invention. The locking unit is adjustable between a release position and a locking position, at least one locking element of the locking unit interacting with an interface of the handgun in the locking position to lock the base plate on the handgun. Preferably, the locking unit is adjustable between the release position and the locking position without tools. The mounting device can advantageously be removed from the handgun in the release position of the locking unit by overcoming the magnetic force of the magnet unit, as in the release position, the locking element of the locking unit is disengaged from the interface of the handgun. In contrast, in the locking position, the at least one locking element of the locking unit is engaged with the interface of the handgun, so that the mounting device is locked to the handgun in the locking position. The interface of the handgun is preferably located on the slide of the handgun in the area of the contact surface of the handgun. The interface may be shaped like a recess that extends transversely to the direction of firing, i.e., transversely to the longitudinal extension of the base plate and / or of the slide of the handgun. This allows for the movement of the base plate, caused by the forces that occur during firing, to be reliably blocked in at least two directions, namely in and against the direction of firing. The recess-shaped interface preferably has at least one locking contour that can interact with a locking element of the locking unit in such a way that, in the locking position, a positive fit is formed between the locking element and the recess. Preferably, the recess has two locking contours formed as undercuts, each of which can interact with a locking element. The recess can be simply designed as an undercut groove, with the groove flanks slanting towards the groove bottom, thus forming an undercut. The prismatic longitudinal edge of a locking element can be brought into contact with a slanted groove flank of the recess in the locking position of the locking unit to form a positive fit. The locking unit enables reliable locking of the mounting device to the handgun, combined with high target precision, as the same relative position to the weapon can easily be attained every time the device is mounted.

[0011] In summary, the mounting device according to the invention allows for easy positioning and fastening of the base plate to a handgun and subsequently a reliable locking of the base plate to the handgun. Advantageously, the mounting device is already fastened to the handgun via the magnet unit when the user operates the locking unit, thereby significantly simplifying the transition of the locking unit from the release position to the locking position, as the mounting device is already positioned on the slide of the weapon. The mounting device according to the invention is based on the fundamental concept that the positioning of the mounting device is effected via the magnet unit, and the locking is effected via the locking unit. The locking element of the locking unit can positively snap into the interface of the handgun in the locking position, ensuring that the mounting device cannot be subsequently removed. Only by deliberately disengaging the locking element from the interface can the mounting device be released and removed from the handgun against the magnetic force.

[0012] The magnet unit may initially be configured in any desired manner, provided that it is capable of generating the holding force required to fixate the mounting device to the handgun. The magnet unit can have at least one magnet, which is arranged in a recess in the mounting surface of the base plate and is essentially flush with the mounting surface or slightly protrudes above the same. A plurality of magnets, preferably two magnets, can be used in a statistical or regular arrangement. The magnet elements can themselves come into contact with the assigned contact surface on the handgun. The recess in the base plate can be completely or partially open towards the mounting surface. Preferably, however, the recess in the base plate for receiving a magnet is closed towards the mounting surface, thereby reliably preventing direct contact between the magnets and the weapon. The magnets can be fixated, for example glued, in their recesses, or they can be slightly movable, so that contact with the handgun is ensured under all circumstances.

[0013] Advantageous embodiments of the invention are the subject matter of the dependent claims. Furthermore, all combinations of at least two features disclosed in the description, the claims, and / or the figures fall within the scope of the invention. It is understood that the statements made regarding the mounting device apply in an equivalent manner to the handgun according to the invention, without needing to be separately mentioned for the latter. In particular, it is understood that customary linguistic modifications or contextually appropriate substitutions of respective terminology—especially the use of synonyms supported by generally accepted linguistic literature—are included in the present disclosure content, even if they are not explicitly mentioned in their specific formulation.

[0014] According to a preferred embodiment, the locking unit can comprise two locking elements in order to reliably lock the mounting device on the handgun, at least a first locking element being mounted so as to be displaceable against a spring force. Preferably, the first locking element is displaceable against a spring force in the direction of firing. The second locking element is preferably engaged in a fixating manner relative to the first locking element. In the release position, the two locking elements are disengaged from the handgun, in particular disengaged from the interface of the handgun. In the locking position, the two locking elements are engaged in a fixating manner with the interface which is preferably arranged in the slide of the handgun, i.e. the locking elements positively snap into the interface of the handgun so that they engage behind said interface. For this purpose the locking elements can be formed as prismatic jaws whose outer contour is complementary to the locking contour of the interface of the handgun.

[0015] The second locking element can preferably be fixedly attached to the base plate so that the second locking element is immovable relative to the base plate. Thus, the first locking element, which is arranged so as to be displaceable relative to the base plate, is also displaceable relative to the second locking element. Preferably, the first locking element can be moved towards the second locking element against a spring force. The second locking element can be fixated to the base plate in a simple manner by means of a screw connection. For this purpose, the second locking element can have a bore with an internal thread into which a screw that extends through the base plate can be screwed.

[0016] The locking unit can be received in a recess in the base plate. In particular, at least the locking elements of the locking unit are received in the base plate. According to this embodiment, the locking unit can be protected from external influences and the space required for the mounting device can be minimized. If the locking unit is received in a recess in the base plate and the magnet unit is also arranged inside the base plate, the external dimensions of the mounting device are essentially defined by the dimensions of the base plate. In other words, the space requirement of the mounting device is determined by the space requirement of the base plate. The base plate can thus form a housing for the magnet unit and the locking unit.

[0017] According to a preferred embodiment, the longitudinal axis of the locking element runs transversely to the longitudinal axis of the base plate. When the mounting device is mounted on the handgun, the longitudinal axis of the locking element then runs transversely to the longitudinal axis of the slide and thus transversely to the firing direction. As a result, the recoil forces that occur when firing with the handgun can be reliably absorbed and a locking of the mounting device according to the requirements can be ensured due to the positive fit between the locking element and the interface of the handgun.

[0018] At least one spring element can be arranged between the two locking elements. The two locking elements can be arranged so as to be moveable towards each other against the force of the spring element. Preferably, a first displaceably arranged locking element can be moved against the force of the spring element in the direction of the second fixed locking element. The at least one spring element can come to rest in a receiving opening of a locking element. To secure the spring element between the two locking elements, one end of the spring element can come to rest in a receiving opening of one locking element in each case. Preferably, two spring elements are arranged between the two locking elements to enable a uniform movement of the first locking element in the direction of the second locking element. The spring element can be designed as a spiral spring, for example.

[0019] The locking unit can be actuated by means of an actuating element. Actuation of the actuating element causes a displacement of the first displaceable locking element relative to the base plate in the direction of the second fixed locking element. The base plate can have a receiving recess for receiving the actuating element, the actuating element being at least partially insertable into the receiving recess and at least partially protruding from the receiving recess in the release position of the locking unit. The actuating element is thus accessible to the user from the outside. Furthermore, the actuating element can be designed in one piece, i.e. monolithic, with a locking element, preferably with the displaceable first locking element. This makes it particularly easy to displace the first locking element by means of the actuating element. The actuating element can be designed as a pushbutton, applying pressure to the pushbutton causing the first displaceable locking element to be displaced relative to the base plate in the direction of the second fixed locking element.

[0020] To secure the locking unit in the locking position, the mounting device can comprise a safety unit. The safety unit ensures that the locking unit cannot be moved from the locking position to the release position in an undesired manner. In particular, the safety unit secures the actuating element of the locking unit against unintentional actuation. This is preferably done by blocking the movement of the actuating element.

[0021] To secure the locking unit in the locking position, the safety unit can have a securing element that is insertable into a recess in the actuating element and prevents unintentional actuation of the actuating element. The securing element can be designed as a pin that is insertable into the recess of the actuating element. The pin is inserted into the recess of the actuating element or engages through the recess of the actuating element and interacts with the locking unit in such a way that a movement of the actuating element and consequently a displacement of the displaceable first locking element is blocked. The securing element can be fixated within the recess of the actuating element without tools by means of a toggle lever or a clamping lever. However, it has proven to be advantageous if the securing element is a threaded pin that can be screwed into the actuating element and / or into a locking element, for example by means of a screwdriver or a wrench.

[0022] According to an advantageous embodiment, the pin extends through the base plate and at least one locking element, whereby the pin can be brought into contact with a further locking element. Preferably, the pin extends through the actuating element, the base plate and the first displaceable locking element and comes to rest against the second fixed locking element. The pin thus interacts with the first and second locking elements in such a way that a movement of the first locking element in the direction of the second locking element is prevented. The second locking element can have a receiving opening for the pin, the pin coming into contact with the second locking element within the receiving opening. In order to preclude any disturbance or impairment affecting the user and also any unintentional actuation of the actuating element when the handgun is triggered, the pin can be inserted into the locking unit, in particular into the recess of the actuating element, preferably in the firing direction and / or along the longitudinal extension of the base plate, the longitudinal extension of the base plate and the firing direction coinciding in accordance with a preferred embodiment of the invention. Furthermore, it has proven to be advantageous if the application of pressure to the actuating element, in particular to a pushbutton, also takes place in the firing direction and / or along the longitudinal extension of the base plate.

[0023] The actuating element and / or at least one locking element can have an internal thread into which the pin that is formed as a threaded pin can be screwed with its external thread. A detachable screw connection can thus be formed between the external thread of the threaded pin and the internal thread of the actuating element and / or the internal thread of the at least one locking element. Preferably, the recess of the actuating element and the displaceable first locking element each have an internal thread whose longitudinal axes are aligned, so that the threaded pin can be screwed into the actuating element and the first locking element, extending through said actuating element and said first locking element. In a simple manner, the threaded pin can be screwed in via a hexagon socket recess arranged on the end face of the threaded pin using a hexagon wrench designed to be complementary to the hexagon socket recess. Tightening the threaded pin using a tool, in particular using the hexagon wrench, enables the application of a tightening torque according to the requirements and thus a secure screw connection.

[0024] According to a variant of the invention, the base plate can have a mounting surface on the underside, the mounting surface being formed from a flat central surface and two curved lateral surfaces each of which laterally adjoins the central surface. This design of the underside of the base plate advantageously results in the base plate, on its underside, i.e. on the side facing toward the handgun in the mounted state, having a shape which is adapted to the contour of the slide of the handgun in the area of the contact surface. Due to this design of the base plate, any undesired displacement of the base plate relative to the handgun transversely to the longitudinal extension of the slide of the handgun can be prevented by the contact of the lateral surfaces with the slide. The mounting surface can be shaped like a cylindrical shell, the diameter of which essentially corresponds to the diameter of the slide of the handgun in the area of the contact surface.

[0025] In order to make it possible to aim at a target with the handgun even in the event of a failure of the auxiliary part arranged on the mounting device, in particular a sighting unit, or also together with an auxiliary part, an auxiliary sight composed of a rear sight and a front sight can be arranged on the base plate. It has proven to be advantageous if the auxiliary part is arranged between the rear sight and the front sight. Preferably, the optical axis of the auxiliary sight coincides with the optical axis of an auxiliary part formed as a sighting unit, so that the user can look through the sighting unit when aiming at a target using the rear sight and the front sight. In the context of the invention, it has been recognized that, as is the case with generic mounting devices, the sight composed of a rear sight and a front sight arranged on the handgun can generally no longer be used when an auxiliary part is attached. However, according to the present embodiment, even if the sight composed of a rear sight and a front sight arranged on the handgun can no longer be used, the auxiliary sight composed of a rear sight and a front sight arranged on the base plate is advantageously still available as a targeting aid in the event of a failure of the auxiliary part.

[0026] A shielding element for shielding a magnetic field can be arranged between the magnet unit and the auxiliary part so that the function of the auxiliary part, in particular a sighting unit, is not undesirably influenced by the magnetic field of the magnets. It is conceivable that a plate or a foil with a magnetic shielding effect is arranged between the magnet unit and the auxiliary part as a shielding element. Preferably, the shielding element is designed as a foil so that the shielding element is easy to handle and only has a low structural thickness. The shielding element can have a cobalt alloy or a nickel-iron alloy. The shielding element is preferably arranged on the surface of the base plate or in the recess that receives the magnets of the magnet unit. Shielding by means of the shielding element can thus prevent impairment of the auxiliary part due to the magnetic field of the magnets of the magnet unit.

[0027] In order to ensure sufficient stability and at the same time easy assembly of the mounting device, it has proven to be advantageous if the base plate is designed in one piece, i.e. monolithic. If an auxiliary sight is provided on the base plate, the base plate is preferably designed monolithic together with the auxiliary sight. The base plate can be produced by milling, for example.

[0028] It has proven advantageous to incorporate an adapter recess into the surface of the base plate. An adapter plate can be inserted into the adapter recess, the auxiliary part, in particular a sighting unit, being able to be positioned and / or fastened on the base plate by means of the adapter plate. The adapter plate is preferably designed to be complementary in shape to the adapter recess. In other words, the adapter plate can be inserted into the adapter recess and is secured within the adapter recess by a positive fit. The adapter plate is preferably trapezoidal. In order to arrange the auxiliary part on the surface of the base plate between the rear sight and the front sight of the base plate, the adapter recess can be incorporated in the surface of the base plate between the rear sight and the front sight of the mounting device. The adapter recess preferably does not fully extend through the base plate, but has a defined depth corresponding to the thickness of the adapter plate. The adapter recess can be incorporated in the base plate above the magnet unit. In the context of the invention, the surface of the base plate is located at the upper side of the base plate, the upper side being the side of the base plate facing away from the weapon when mounted.

[0029] The adapter plate can have at least one positioning pin for positioning an auxiliary part on the surface of the base plate. Preferably, the adapter plate has two positioning pins for positioning an auxiliary part on the surface of the base plate. Using the at least one positioning pin, the auxiliary part can easily be positioned on the base plate by means of a plug connection and, if necessary, can subsequently be screwed to the base plate. The plug connection can be established via the positioning pin, preferably via two positioning pins, which can be inserted into pin recesses in the auxiliary part that are designed to be complementary to the positioning pins. In other words, the auxiliary part can be plugged onto the positioning pins when being placed on the base plate and thereby can be correctly oriented relative to the base plate. In addition, the auxiliary part can be screwed to the base plate. Preferably, the auxiliary part can be connected to the base plate by means of a screw connection and a plug connection. It has also proven advantageous if the adapter plate forms at least part of the surface of the base plate. In this way, the surface of the base plate is easily completed by the adapter plate, which also completes and maximizes the support surface for the auxiliary part. The adapter plate can have a support plate and at least one positioning pin arranged on the support plate and extending upward in the mounted state. Preferably, the support plate of the adapter plate is trapezoidal. If the adapter plate forms at least part of the surface of the base plate, the surface of the support plate of the adapter plate and the surface of the base plate form a flat surface by being arranged flush with each other. The depth of the adapter recess then corresponds to the thickness of the support plate. In the context of the invention, the term “support plate” refers to a flat piece of material, in particular a rigid material, which has the same thickness throughout and is bounded on two opposite sides by a flat surface that is very large in relation to the thickness.

[0030] In order to ensure sufficient stability and at the same time easy assembly of the mounting device, it has proven advantageous for the adapter plate to be designed in one piece, i.e., monolithic. If at least one positioning pin is provided on the adapter plate, the adapter plate is preferably designed monolithic together with the at least one positioning pin. The adapter plate can be manufactured by milling, for example.

[0031] In a further aspect, the invention relates to a mounting system comprising a mounting device according to any embodiment of the invention and a plurality of, in particular different, adapter plates which can be interchangeably received in the adapter recess. This provides a set of preferably different adapter plates from which a suitable adapter plate can be selected depending on the situation, in particular depending on the auxiliary part to be attached. The different adapter plates can preferably differ in the number of positioning pins and / or in the arrangement of the positioning pins on the support plate of the adapter plate. Preferably, the support plate of the plurality of different adapter plates is identical in design, so that the adapter plates differ only in the design and / or arrangement of the positioning pins. Within the scope of the invention, it was recognized that the design of the mounting device may have to be variable in order to be able to attach different auxiliary parts, in particular different sighting units. The mounting system offers the advantage that when changing between different auxiliary parts, in particular different sighting units, it is not necessary to exchange the entire mounting device, but rather only the adapter plate can be replaced in a simple manner. Accordingly, the mounting system comprises different adapter plates, each of which provides a mounting option for a specific auxiliary part, in particular for a specific sighting unit. In summary, the mounting device with an adapter plate, and in particular the mounting system comprising a mounting device and a plurality of different adapter plates, is flexibly and universally applicable and, in particular, adaptable to different auxiliary parts.

[0032] The mounting device can preferably be used to fasten an auxiliary part in the form of a red dot sight, a prism sight or a reflex sight to a handgun.

[0033] In a second aspect, the invention relates to a handgun with a previously described mounting device for fastening an auxiliary part to the handgun. The afore-described device according to the invention can be used universally and can therefore interact with a large number of different handguns. As described above, the base plate of the mounting device is detachably connected to the slide of the handgun. In this case, it is preferable to arrange the base plate relative to the slide of the firearm in such a way that the longitudinal axis of the base plate runs parallel to the longitudinal axis of the slide of the firearm, and the longitudinal axis of the locking element of the locking unit, in particular the longitudinal axis of the prismatic jaw of the locking element, runs transversely to the longitudinal axis of the slide.

[0034] It is understood that the embodiments and examples of embodiments mentioned above and to be explained below can be realized not only individually, but also in any combination with one another, without departing from the scope of the present invention. It is also understood that the embodiments and embodiment examples mentioned above and to be explained below relate in an equivalent or at least similar manner to the handgun according to the invention, without being mentioned separately for the latter.BRIEF DESCRIPTION OF THE DRAWINGS

[0057] FIGS. 1 to 6 show the mounting device 01 according to the invention with a handgun 02, the mounting device 01 enabling the fastening of the sighting unit 03 to the handgun 02. For fastening the sighting unit 03 to a handgun 02, the base plate 05 is connected to the sighting unit 03, which is designed as a reflex sight. The sighting unit 03 can be fastened to the surface 52 of the base plate 05 by means of a screw connection. The base plate 05, in turn, is connected to the handgun 02, specifically to the slide 15 of the handgun 02. For easy and quick positioning of the base plate 05 on the contact surface 21 at the slide 15 of the handgun 02, the mounting device 01 comprises a magnet unit with two magnets 09. Using the magnet unit 20, the mounting device 01 can be positioned with the mounting surface 51 on the contact surface 21 of the handgun 02 and can then be locked in place using the locking unit 30, so that recoil forces also occurring during firing can be reliably absorbed. Furthermore, it can be taken from FIGS. 1 to 6 that an auxiliary sight 13, composed of a rear sight and a front sight, is arranged on the base plate 05, with the sighting unit 03 being mounted on the base plate 05 between the rear and front sights of the auxiliary sight 13. The optical axes of the auxiliary sight 13 and the sighting unit 03 are aligned in such a way that, in the event of a failure of the sighting unit 03, the auxiliary sight 13 can still be used. The optical axes of the auxiliary sight 13 and the sighting unit 03 run parallel to the firing direction S and thus also parallel to the longitudinal extension of the slide 15 of the handgun 02. The longitudinal axis LB of the base plate 05 also runs along the firing direction S. The actuating element 14 of the locking unit 30 can be actuated from the rear, i.e. from the end of the mounting device 01 remote from the muzzle of the handgun 02. For actuation, pressure must be applied to the actuating element 14, which is designed as a push button, so that the actuating element 14 is at least partially pushed into the base plate 05 in the firing direction S. This allows the locking unit 30 to be moved from the locking position to the release position. The differences between the locking position and the release position of the locking unit 30 are shown in particular in FIGS. 7a to 11b and will be explained below.

[0058] A synopsis of the exploded views shown in FIGS. 5 and 6 shows in particular the structure and the mode of operation of the locking unit 30 of the mounting device 01 according to the invention for fastening a sighting unit 03 to a handgun 02. The two locking elements 06, 07 of the locking unit 30 are arranged within a recess on the underside of the base plate 05. The locking element 07 is fixedly attached to the base plate 05 by means of the screw 11, which extends through the base plate 05 and interacts with an internal thread inserted in the locking element 07. The locking element 06 is designed in one piece with the actuating element 14 and can be inserted into the recess on the underside of the base plate 05 in such a way that the actuating element 14 extends through the base plate 05. Two spring elements 08 are arranged between the locking elements 06 and 07, the locking element 06 being movable towards the fixed locking element 07 against the spring force of said spring elements (08) in order to move the locking unit 30 from the locking position to the release position As long as no pressure is applied to the actuating element 14, the locking element 06 is moved away from the fixed locking element 07 by the force of the spring elements 08, so that the prismatic jaws 61 and 71 of the locking elements 06 and 07 in the interface 04 of the handgun 02 engage behind the slanted groove flanks of the interface 04. This positive engagement of the prismatic jaws 61 and 71 with the interface 04 in the locking position of the locking unit 30 allows the mounting device 01 to be reliably secured to the handgun 02. It can be seen that the interface 04 is designed as a groove extending transversely to the firing direction S and extending through the slide 15, with slanted groove flanks. Consequently, the longitudinal axis LR of the locking element, in particular of the prismatic jaws 61 and 71, also runs transversely to the firing direction S.

[0059] To prevent an unintentional moving of the locking unit 30 from the locking position to the release position, a safety unit 40 is provided. The securing element 10 of the safety unit 40, which in the illustrated embodiment is designed as a threaded pin, can be guided along the firing direction S through the actuating element 14 extending through the base plate 05 and the movable locking element 06, and can be brought into contact with the fixed locking element 07. The external thread 18 of the threaded pin interacts with an internal thread 17 inserted into the actuating element 14 and into the locking element 06. Depending on the screwing depth of the securing element 10, a desired spacing between the locking elements 06 and 07 can thus be defined, i.e. an actuation of the actuating element 14 can be prevented. Only once the securing element 10 is again spaced from the fixed locking element 07, the actuating element 14 can be actuated again to move the locking unit 30 from the locking position to the release position. Furthermore, it can be seen from the synopsis of FIGS. 5 and 6 that within the base plate 05, a magnet unit 20 comprising two magnets 09 is received, which serves to position and support the securing of the mounting device 01 on the slide 15 of the handgun 02.

[0060] FIGS. 7a to 11b show the embodiment of the mounting device 01 according to the invention already shown in FIGS. 1 to 6 taken in isolation. A synopsis of FIGS. 7a to 11b again clearly shows the structure according to the invention and the mode of operation of the mounting device 01, the mounting device 01 being shown in FIGS. 7a to 8b together with the sighting unit 03 and being shown in FIGS. 9a to 11b without the sighting unit 03.

[0061] It can again be seen that the sighting unit 03 is arranged between the rear sight and the front sight of the auxiliary sight 13 and is detachably connected to the base plate 05. In a first step, the magnets 09 of the magnet unit 20 shown in FIGS. 8a to 10b, which interact with a ferromagnetic area of the contact surface 21 of the handgun 02, are used to fasten the mounting device 01 to a handgun 02. For fastening the mounting device 01 of a handgun 02, the mounting surface 51 of the mounting device 01 can be brought into contact with the contact surface 21 of the handgun 02, which is not shown in FIGS. 7 to 11. For this purpose, the mounting surface 51 can be designed so as to be complementary to the slide 15 of the handgun 02 and, as can be taken in particular from FIGS. 8a and 8b, has a central surface 51a and lateral surfaces 51b each adjoining the central surface 51a, the lateral surfaces 51b being curved.

[0062] To lock the mounting device 01 on the handgun 02, the locking unit 30 can be moved from the release position to the locking position. FIGS. 7a, 8a, 9a, 10a and 11a each show the mounting device 01 in the locking position, whereas in FIGS. 7b, 8b, 9b, 10b and 11b the mounting device 01 is shown in the release position. In the locking position, the two locking elements 06, 07 are pushed apart due to the force of the spring elements 08, whereby the prismatic jaws 61, 71, if they are inserted into the interface 04 of a handgun 02, can form a positive fit with the interface 04. In addition, the actuating element 14, which in the present case is designed as a push button and is designed in one piece with the movable locking element 06, is pushed out of the base plate 05 due to the force of the spring elements 08. In contrast, in the release position, the actuating element 14 is pushed further into the base plate 05 against the force of the spring elements 08. By inserting the actuating element 14 into the base plate 05, the locking element 06 is pushed in the direction of the locking element 07, as a result of which the prismatic jaws 61, 71 of the locking elements 06, 07 are disengaged from the interface 04 not shown in FIGS. 7 to 11.

[0063] As described above, the securing element 10 of the safety unit 40 can be screwed into the actuating element 14 and the movable locking element 06 until the securing element 10 comes into contact with the fixed locking element 07, thereby blocking an actuation of the actuating element 14. If an actuation or movement of the actuating element 14 is blocked, the locking element 06 cannot be moved towards the locking element 07, and the prismatic jaws 61, 71 of the locking elements 06, 07 remain spaced apart and thus engaged with the interface 04 of the handgun 02. Consequently, the locking unit 30 is secured against undesired movement from the locking position to the release position by means of the safety unit 40.

[0064] The mounting device 01 shown in FIGS. 12 to 16 largely corresponds to that shown in FIGS. 1 to 11, but differs from the same in that the mounting device 01 shown in FIGS. 12 to 16 has an adapter recess 12 for receiving an adapter plate 16, the adapter plate 16 having positioning pins 161 for positioning a sighting unit 03 on the surface 52 of the base plate 05. In contrast, the base plate 05 of the mounting device shown in FIGS. 1 to 11 can be formed in one piece with the positioning pins 161, which, however, are not shown in FIGS. 1 to 11. In all other respects, the mounting device of the embodiment shown in FIGS. 12 to 16 corresponds to that shown in FIGS. 1 to 11, which is why reference is made to the description thereof in order to avoid repetition.

[0065] FIGS. 12, 15, and 16 show the mounting device 01 according to the invention with a handgun 02, the mounting device 01 enabling the sighting unit 03 to be attached to the handgun 02. To attach the sighting unit 03 to a handgun 02, the base plate 05 can remain connected to the sighting unit 03. The sighting unit 03 can be positioned on the surface 52 of the base plate 05 by means of the positioning pins 161 and can then be fastened to the surface 52 of the base plate 05 by means of the screws 19. A synopsis of FIGS. 12 to 16 shows that the adapter plate 16 comprises the positioning pins 161 for positioning the sighting unit 03 relative to the base plate 05 and thus also relative to the handgun 02. When the mounting device 01 is mounted, the positioning pins 161 extend upward away from the support plate 162 of the adapter plate 16. According to the embodiment shown, two positioning pins 161 are arranged on the adapter plate 16. As can be seen in particular from FIGS. 13 and 14, the positioning pins 161 can be arranged at different positions on the support plate 162 of the adapter plate 16, depending on the embodiment of the adapter plate 16. This allows the mounting device 01 to be adapted to different sighting units 03. Depending on which sighting unit 03 is to be used, the adapter plate 16 can be easily exchanged. The adapter plate 16 can be inserted into the adapter recess 12, which is incorporated in the surface 52 of the base plate 05, and is secured in the adapter recess 12 by a positive fit. The support plate 162 is preferably designed as a trapezoidal plate and the adapter recess 12 is designed to be complementary to the support plate 162, preferably also trapezoidal. The positioning pins 161 are preferably designed to be circular cylindrical. FIGS. 15 and 16 also show that the adapter recess 12 does not completely extend through the base plate 05 and is incorporated in the base plate 05 above the magnet unit 20. Preferably, but not exclusively, the adapter recess 12 can be arranged at the end of the mounting device 01 close to the muzzle of the handgun 02. In order to be able to attach the sighting unit 03 between the rear sight and the front sight of the auxiliary sight 13 on the base plate 05, the adapter recess is incorporated in the base plate 05 between the rear sight and the front sight of the auxiliary sight 13 in accordance with the embodiment shown. The different adapter plates 16 shown in FIGS. 13 and 14 can, for example, be components of a mounting system consisting of the mounting device 01 according to the invention corresponding to the second embodiment and a plurality of adapter plates 16. Due to the fact that this mounting system has a plurality of adapter plates 16 that can be interchangeably inserted into the base plate 05, the mounting system offers the possibility of easily adapting the mounting device 01 to different sighting units 03.LIST OF REFERENCE SIGNS
