Abstract

An accessory mounting device for use with firearms is disclosed. The mounting device includes a first pin having a first head and a second pin having a second head, wherein the second head projects radially beyond the second pin only on one side of the second pin. The device further includes first and second apertures to receive the first and second pins, respectively, and a first undercut associated with the first aperture, wherein the first undercut is compatible with the first head and a second undercut associated with the second aperture, wherein the second undercut is compatible with the second head. Also included is a spring-loaded locking device attached to the second pin and a handle associated with the spring-loaded locking device. The handle moves the second pin against the force of the spring axially in the direction of the second head so that when the second pin is turned by the handle, the second head pushes against the force of the spring on the second undercut.

Description

The invention relates to a mounting device, which forms an interface between a device, in particular a weapon, and an attachment, with two or more substantially parallel, spaced pin and two or more holes as receptacles for these, which are each equipped with an undercut, and with a locking device which is spring-loaded with a spring and which is assigned to one of the pins and has a handle; in which the undercuts of two bores are formed either at their sides facing away from each other and / or on the sides facing each other, the undercuts of the bores are chamfered, carry the pins compatible with the beveled undercuts formed heads, and one of the pins by means of the handle is rotatable woebi the head of this pin only on one side over this radially overhangs. (Preamble of claim 1).

In conventional rifles with steel housing, it is customary to attach a mounting device, the so-called "scope mount" on the steel housing for attaching a rifle scope on the weapon. Such a scope mount is often very expensive and not very durable. Cheaper assemblies, e.g. the so-called "postponement assembly", are clamped at the jaws on a prism rail, often their position that they take after mounting on the rifle, not sufficiently reproduce after removal and reapplication.

• erheblichen Stößen standhalten müssen, ohne sich zu verstellen (Montage z. B. auf einem Maschinengewehr, das seinerseits an einem Geländefahrzeug montiert ist),
• große Kräfte übertragen müssen (wenn sie z. B. nicht nur ein leichtes Zielfernrohr, sondern eine schwere Gefechtsoptik und/oder Gefechtselektronik oder eine zweite Waffe mit der ersten Waffe lagegenau und voll reproduzierbar verbinden sollen), aber dennoch
• einfach, kostengünstig, klein in der Ausführung und bequem auf- und absetzbar sein sollen.

Military rifles dramatically exacerbate the problems of assembly because of military installations

• have to withstand considerable shocks without being misaligned (eg mounting on a machine gun, which in turn is mounted on an off-road vehicle),
• large forces (if, for example, they should not only connect a light riflescope, but rather a heavy battle optics and / or combat electronics or a second weapon with the first weapon in a precise position and fully reproducible), but nevertheless
• simple, inexpensive, small in design and easy to be put on and absetzbar.

It turns out that these assemblies should rather be called "interfaces", which should allow for devices of all kinds, which must use a strictly defined position when used together, the simple separation and re-composition without the defined position assignment sometime in any way is impaired.

It is known a military riflescope assembly (the sniper rifle of the former GDR), in which two pins are attached to the scope, while the rifle in front of and behind the closure each have a pin receptacle is provided. With the telescope held transversely to the axis of the soul, the front pin is placed in its receptacle, and then the scope is rotated by 90 ° until it is parallel to the axis of the soul. In this case, engages under a projection of the front pin an undercut in the front receptacle, and the rear pin engages laterally in the rear receptacle. To release the operation of a handle on the rear receptacle releases the rear pin again. The riflescope is pivoted again by 90 ° and can then be lifted from the front intake.

As easy as this assembly appears, it is nevertheless only suitable for the special case: an exact fitting of all parts is necessary, which makes the interchangeability of the riflescopes or accessories in particular practically impossible. In particular, tolerances can hardly be compensated. Furthermore, the pins have a fairly large distance, which is due to the design of the rifle, but helps to minimize any tolerances. The recordings are therefore individually attached to the weapon, the parts of which must be massive enough to accept this attachment.

The generic DE 94 06 408 U which forms a basis for claim 1, shows a mounting device for a riflescope, in which the pivotable with a pivot pin is mounted without play by a centering countersunk screw and a resilient wave washer to the mounting device. The US 4,205,473 A also shows a riflescope mounting, in which the rotatable pin is fixed by means of a turning screw.

It is an object of the invention to find a mounting device in which the attachment wobble-free, but not overly tight can be mounted.

• der eine der Zapfen gegen die Kraft der Feder axial in Richtung seines Kopfes beweglich ist, so daß beim Verdrehen dieses Zapfens mittels der Handhabe dessen Kopf mit der kompatiblen Ausbildung gegen die Kraft der Feder auf der abgeschrägten Hinterschneidung der zugehörigen Bohrung aufläuft.

To solve this problem it is proposed that in a generic mounting device,

• one of the pins against the force of the spring is axially movable in the direction of its head, so that when turning this pin by means of the handle whose head runs with the compatible training against the force of the spring on the chamfered undercut of the associated bore.

As already noted at the beginning, the mounting device is especially designed for the attachment of attachments on a weapon, But it can also serve for positionally accurate and separable assembly of devices of all kinds.

"Attachment" is preferably understood to mean a battlefield computer, target optics or target electronics (e.g., riflescope, night aiming device, laser aiming device) or a second weapon (e.g., mounted grenade launcher, rapid-fire rifle).

A beveled undercut is understood to mean an increase in the bore diameter present on the outside mouth of the bore, the term "beveled" describing a generally continuous transition (conical, parabolic, hyperbolic, domed or otherwise) from the inside to outside mouth ,

By "handle" is meant an actuator for applying force, such as a lever, but it may also be a servo motor or the like.

By "head" is meant a radial end projection of the pin. However, it may extend in a special case, the pin over the head.

The two holes are preferably formed on the device or associated with this, preferably a weapon (usually a handgun), while the pins are assigned to the attachment, as well as the one of the pins associated with the handle.

The holes (the undercuts remain unconsidered) preferably have a center distance that is smaller than the center distance of the pins (whose heads are disregarded). It is not necessary that the pins are placed in the direction of their axes in the holes. Rather, it is preferred that the mutual center distance of the holes and the the pin does not match, but is tuned so that the axial distance of the pin is a little larger than that of the holes: so first, the rigid pin is inserted obliquely into the associated hole and hooked with the head behind the undercut. For this purpose, the bore must be large enough to let the head of the pin when it is slightly tilted pass. Then the attachment, which usually carries the pins, pulled in the direction of the rigid pin until the movable pin can come into its associated hole. Here, the head of the axially and rotatable pin must have a rotational position, that now this movable pin can come into its associated hole. Now both pins sit in their holes.

Now, the movable pin is rotated by the handle and runs against the chamfer of the undercut. The rigid pin presses with his head firmly against the undercut of the associated hole. Upon further rotation of the handle of the movable pin is moved axially against the force of the spring, because his head could not otherwise be twisted otherwise: the head, which rests firmly against the undercut, now runs along their bevel outward and is to to be able to do this, moved axially against the force of the spring. He dips with continued rotation possibly something in its associated hole until it has reached its end position.

Here, the term "compatible" means that the undercut and the head must be designed so that the movement of the pin just described is possible. In practice, the beveled surfaces at the undercut and the head are complementary or, as will be described later, even better "nearly complementary" formed.

When using a spring, this ultimately ensures the constant pressure with which the pins are pressed into the bore. In this case, the preferably rigid pin is pressed over the chamfer of the undercut, while the movable pin strives on the undercut to pull apart the holes, and is otherwise pressed by the strong spring.

It is preferred to form the surfaces around the pins complementary to the surfaces around the holes, for example in the form of planar, perpendicular to the respective axes surfaces.

It is ultimately irrelevant how far the movable pin has moved axially or not. It is only essential that he transmits the force exerted by the locking device, in particular the spring force on his head on the associated undercut. When using a spring, the mounting device according to the invention is adapted to accommodate significant tolerances, in contrast to known pin assemblies that had to be tuned to the finest. For this reason, the mounting device according to the invention is particularly suitable for a variety of attachments and ensures their safe placement.

When the undercuts facing away from each other, the associated bores can be formed even in a thin-walled housing of a weapon, since the holes are pulled apart with mounted attachment. A sheet metal wall, which runs straight between the holes, can absorb very large forces between these two holes without deforming.

Both holes can be symmetrical to each other, ie by means of the same tools. So a cheapening of the production is possible.

The heads can sit flat in the undercuts. So it is ensured that the inter-engaging surfaces wear as little as possible. However, it requires a great manufacturing accuracy, as well as embarrassing cleanliness. In particular, the complementary mating surfaces must not exhibit any corrosion or contamination.

In order to avoid such problems, it is proposed according to an embodiment of the invention that the heads rest on the undercuts each along two abutment lines. Thus, the pin with his head is theoretically at the undercut only in two-line contact, which ensures best reproducibility of the position of the pin relative to the bore.

An example is intended to explain this geometry in more detail; a radial cut (with respect to the hole and the pin) in the area of the undercut when the mounting device is fully assembled is considered:

The bore has a circular circumference which is interrupted by an outwardly extending arc of smaller radius. The transition from the circle with the larger radius in the circular arc with a smaller radius is in each case theoretically in an edge. Each edge can be broken by a tangent to both circles. The wrap angle of the circle section with the larger radius is larger (eg 240 °) than the wrap angle of the circle section with the smaller radius (this is eg 120 °).

The pin has a circular cross-section, and the head also. The radius of the pin is slightly smaller than the larger radius of the hole, and significantly larger than the smaller radius of the hole. Both radii of pin and head have the same center, and the radius of the head must be larger. The head extends over an angular range which is dimensioned such that, on the one hand with locked attachment two nearly parallel axes abutment lines of the head can form on the bevelled undercut and on the other hand, the head for mounting the attachment to the device in the circular portion of the bore with the larger radius (eg the angular range is about 60 °).

When the mounting device is fully assembled, the head is fixed in the radial direction in the undercut, along the above-mentioned edges; in practice along two narrow contact strips transverse to the above-mentioned tangents.

On both sides of these contact strips there is a small distance between the surfaces of the undercut and the head, so that contamination or minor corrosion can be cleared to this distance and does not remain in place, where then the accuracy of storage production would be affected.

The pins can be attached to the attachment individually, z. B. by means of two separate rings on a telescopic sight. However, this must then withstand the considerable forces applied to the pins after assembly (in this case compressive forces).

To overcome this problem, it is proposed according to an embodiment of the invention that the pins in a single, sitting separate component. This component can be made of steel, aluminum, a carbon fiber composite material, etc. and intended for attachment to an attachment. In any case, it has a rigid component, in which the two pins are inserted, and despite the forces acting on the pins is stable enough not to deform.

The respective attachment needs to be able to carry only this component, but does not have to absorb any forces, apart from its own mass forces. It is also readily possible to complete existing implements by mounting the said attachment. The separate component may well be specially shaped, such as a cylindrical trough, in which the housing of a rifle scope can be glued.

Also, the holes may be formed approximately in the housing of a rapid-fire rifle, the sheet is crimped around the holes to form the undercuts. However, it is preferred that the holes sit in a single, separate component. Here, the carrier, which connects the two holes, the resulting tensile forces. If such a carrier, such as a steel strip, placed on the housing of a weapon, welded about, then the housing wall closes the bottom (side of the undercuts) of the holes, so that at most can accumulate in this dirt, but not in the mechanism of the rifle can penetrate.

However, such a closure of the holes can also be included in the component. It is therefore preferred according to an embodiment of the invention that the holes of the component are closed on the side of the undercuts at least after assembly of the component. It can be about a sheet on the component be placed, which closes the holes. In this way it is avoided that moisture threatens a corrosion-prone housing. Of course, the holes may be open towards the inside of the housing (since, for example, optics are always mounted on the rifle in the operating state and thus close the bores to the outside), which has the advantage of easier cleaning of the bores.

If a thin-walled plastic housing is used, then the component anyway requires at least one anchoring point which is in fixed position assignment to the barrel of the weapon. Here, the cover of the holes avoids that dirt or sand, which has got into the holes, is pressed by the pins in the plastic housing wall.

The movable pin can be easily guided in its rotation and translation movement in a transitional bore. It is also possible to use in this hole a lining of bearing metal o. The like. To facilitate the movement, without one would have to accept a game in purchasing.

Preferably, however, just the opposite is proposed: not the game should be made as small as possible, but it is proposed that the attachment two supports, preferably in the form of two fork branches, for guiding the movable pin, such that the pin at mounted attachment in each support along two substantially paraxial bearing surfaces rests, wherein the two investment lines of the device facing support are each offset by substantially 180 ° to both the two investment lines of the device facing away from the support and on the other hand, the two investment lines at the undercuts in the Drilling.

If the movable pin is rotated so that it rests with its head against the undercut and moves axially against the force of the spring, then the head is preferably seated on two investment lines, while the pin is also supported on the opposite side on two investment lines, which are located in the hole in one of the two fork branches. These two investment lines in turn are opposite to the aforementioned two other investment lines in the bore of the other fork branch. It is thus made a strictly defined position of the pin when it engages in the associated undercut.

The movable pin retracts against the action of the spring an axial distance. In this case, the spring must be designed so that it preserves the seat of the mounting device, even if it should be exposed to considerable mass forces. This can lead to considerable difficulties, especially as the case is conceivable that the head of the pin does not dive far enough into the associated bore, so that the head of the pin can run along the undercut. Here, it is therefore preferred that the spring is biased and is released during the rotation of the pin only when the head of the associated pin is already partially over the undercut of the associated bore.

The pin is therefore always in a position in which it is already loaded so far from the spring that he basically has to carry out little or no axial movement during rotation. However, the spring is released towards the end of the rotation, so that under all circumstances a sufficient contact force of the spring is ensured.

The handle could be a lever which is simply mounted radially projecting on the movable pin. The solution is preferred with the protruding lever from the pin, however, developed to the effect that, with radially mounted on the handle handle, the lever rests on a running in a radial plane guide over most of its pivotal movement, which only in the end of the pivoting movement, when the head over the undercut is located, is omitted. It is thus provided a simple arrangement to ensure that the pin is full and unhindered acted upon by the spring, shortly before he has reached its end position.

The larger the pivoting range of the movable pin and thus the handle, the wider the head of this pin can be. Therefore, it is proposed that the pivotal range of the movable pin is about 180 °.

Because of the spring forces, the friction that acts on the head of the movable pin, quite large, so that the handle remains in the assumed position. Nevertheless, it is preferred that the handle is fixed in a position in which the movable pin is fully loaded by the spring. This fixation is an additional safeguard, which ensures that the handle remains in place with the mounting device in place. At the same time, this layer is an indication that the mounting device is assembled and fastened.

The fixation can be done with permanent attachment, for example by a screw that determines the handle. However, it is preferred that the fixation is designed as a latching device. Thus, there is hardly a noticeable delay when setting and releasing the handle. Nevertheless, this is reliably determined in their locked position.

The locking device may be a sprung pawl. An advantageous embodiment of the invention, however, is that the latching device is formed as a notch on the component carrying the pin, in which the slightly resilient and / or loaded by the spring handle is incident. Since the handle must overcome considerable forces during rotation of the pin, it must have a considerable length and thus could be resiliently deformable. But also the associated pin takes only by the spring action its end position, so that the handle firmly connected to this pin then, if it is exposed to the full effect of the spring to perform a sprung transverse movement is capable. In any case, such a notch has proven that it holds the handle by means of spring forces in their position, but does not require its own component.

The spring could be a powerful coil spring, such as the valve spring of an internal combustion engine. It is preferred that the spring is designed such that it can provide a large spring force in a small space. Such springs may be a cup spring bundle, a coil spring, a plate spring, etc. For example, disc springs can be tuned due to their special characteristics so that when the handle falls into its final position, the spring constant increases.

An alternative training is that the spring is formed integrally with the associated pin and is preferably formed in the form of a slotted pin or tube. The spring bundle or the spring is thus a captive part of the pin and does not require its own component.

Preferably, the holes are formed in a Picatinny rail or other common for weapons interface, whereby the user advantageously has both mounting options alternatively or in parallel.

Preferably, the attachment comprises a Picatinny rail or other common weapon interface, whereby, for example, only "Picatinny" attachable "old" attachments can be attached to the weapon or, for example, worn (made of very light or cheap material) Picatinny Rails can be replaced very quickly.

The FIGS. 1 to 5 show the first embodiment.

The mounting device consists of an arms-side component 1 and an attachment-side component 3, which can be assembled or separated and fixed means are not shown here on a weapon or on a device attachable here.

The weapon-side component 1 has a planar mounting surface 5 and is penetrated by two holes 7, 9, which are perpendicular to this surface and thus parallel to each other. These holes 7, 9 have a non-circular portion and are the same, but mutually mirrored.

Each bore 7, 9 has a cylindrical portion 11 of radius R (not shown) which is flared by an axially parallel off-center portion 13 having a radius r (not shown). Where R> r. Both bore sections 11, 13 are connected by tangential surfaces 17 which enclose an angle in the direction of the section 13, preferably of approximately 30 ° (to the central axis). The smaller bore portions 13 are respectively on the side of the bore portion 11, which are remote from each other. The holes are thus symmetrical to each other.

On the viewer facing ( Fig. 1 to 3 and 5b ) Underside of the weapon-side member 1, the smaller bore portion 13 each countersunk conically, so that there are undercuts 15, which expire in the tangent surfaces 17.

The observer facing bottom of the holes 7, 9 may be covered.

The attachment-side component 3 has a rigid pin 19 and an axially movable and rotatable pin 21. Both pins 19, 21 are substantially parallel to each other.

Each pin 19, 21 has a shaft 27, 29, and at its free end a head 23, 25. The radius of each shaft 27, 29, which is cylindrical, is greater than r and smaller than R. From this shaft 27th Starting from the rigid pin 19, the head 23 extends as a truncated cone whose cone angle corresponds to the conical countersinking of the bore 7, 9. The head 23 widens, starting from the lower (the viewer facing) end of the pin 19.

When the pin 19 is seated in the associated bore 7 in the fully assembled state of the mounting device ( Fig. 1 ), then the frustoconical head 23 rests on the undercut 15 along two abutment lines which are generatrices of the undercut and the frusto-conical surface.

The head 25 of the movable pin 21 has the same geometric configuration as the head 23 of the rigid pin 19, but it is still milled on the edge, along two planes, each containing a generatrix of the pin 21 and each other at an angle of 90 ° lock in. This angle is rounded along the circumference of the pin 21.

The pin 21 is rotatable by a handle 31 by 180 °, in such a way that the head 25 once, with projecting handle 31 (FIG. Fig. 2, 3rd . 4 ), in a position in which it faces the rigid pin 19, and when applied handle ( Fig. 1 ) facing away from the rigid pin 19. In the latter State, the head 25 is in engagement with the undercut 15 of the associated bore. 9

Again, the engagement takes place along two generatrices of the undercut 15 and the head 25th

Now, the distance between the holes 7, 9 does not correspond to the distance between the pins 19, 21, but is a little smaller. But since the head 25 reaches its final position, he has a little on the viewer of the Fig. 1 to move. This is done by compressing the plate spring package 33rd

If the mounting device, starting from the location of the Fig. 2 when assembling the location of Fig. 1 reached, then pivots the handle 31 from the position of Fig. 2 180 ° in the position of Fig. 1 , In this case, the handle 31 falls into the notch 37 a.

This collapse is achieved once by the inherent resilience of the handle 31 and in the main by the inclination of the pin 21 against the action of the plate spring package 33. The pin 21 is in fact mounted with clearance and has in the storage 35 a recess so that it ultimately only along two generatrix of the bearing 35 is seated when the head 25 in the position of Fig. 1 located. This will now be with reference to Fig. 5 explained in more detail. The attachment-side member 3 is forked at its end receiving the movable pin 21 and there has a device-side member 1 facing away from the fork 51 and a component 1 facing fork load 53. Each fork 51 and 53 is provided with a pin 21 receiving bore. The bore in the device-side member 1 facing away from the fork 51 has in principle the same shape and orientation as the bore 9 in the device-side member 1, but without having an undercut.

The bore in the other fork 53 also has the same shape in principle, but is rotated by 180 °. Overall, therefore, the holes change from the device-side component 1 in the direction of the implement-side device 3 with a large radius R and small radius r. When mounted attachment of the pin 21 is located in each hole along two axis-parallel investment lines, from hole to hole, the two investment lines are offset by substantially 180 °.

The handle 31 is led out through a radial slot 39 from the device-side component 3. This radial slot 39 is bounded by a radial surface 41 on which the handle 31 is seated due to the action of the spring assembly 33 ( Fig. 2, 3rd . 4 ). Only when the handle 31 almost reaches its end position ( Fig. 1 ), it passes over a recess 43, over which the spring assembly 33 is given a greater spring travel and the handle 31 no longer limits the spring travel. Thus, the spring assembly 33 is always biased.

The shooter has the handle 31 always in his line of sight and can respond immediately if they should not have fallen into the notch 37.

By the way, the attachment-side component 3 has projecting surfaces 45 which extend complementary to the mounting surface 5 and ensure a good fit of the components 1 and 3 on one another.

Fig. 6 shows an alternative embodiment of the pin 21 with integrally connected spring package 33 '.

Fig. 7a and b show a second embodiment in which the weapon-side member 1 in succession a plurality of holes 7 '(in the case shown 5 holes) are provided, the respective beveled undercuts 15 and 15' to the facing each other Sites. A bore 7 'thus has two undercuts 15 and 15' respectively in the direction of their neighboring bore 7 '. The outer holes 7 'have undercuts 15 and 15', which point outwards, that are facing away from each other. The two pins 19 and 21 of the device-side component 3 can now in two arbitrary preferably adjacent (but possibly also some intermediate holes 7 'skipping over) holes 7' are used, whereby the device-side component 3 can be mounted in different positions on the weapon-side component 1 , Due to the "two-sided" design of the undercuts 15 and 15 'in the individual holes 7' are at a corresponding distance of the pins 19 and 21, the two holes 7 'with inserted pins 19 and 21 either on train ( Fig. 7a ) or on pressure ( Fig. 7b ) charged.

Of course, more than one fixed and / or one movable pin 19 and 21 may be provided which are received in mounted device-side member 3 in a plurality of holes 7 '. For example, with two fixed and one movable pin, a triangle of forces can be clamped, with a correspondingly higher number of parallelogram forces, etc.

Fig. 8 shows a third embodiment in which, in contrast to that in the FIGS. 1 to 5 shown first embodiment, the mounting device is not locked by twisting but by a displacement of the movable pin and unlocked. In the FIG. 8 are similar components as in the FIGS. 1 to 5 denoted by the same reference numerals. For their description, reference is made to the above description of the first embodiment. At this point, only the different components to the first embodiment will be described.

The mounting device comprises a pin 60 which is displaceable in its longitudinal direction and which, guided by a recess 61, is displaceable on and away from the rigid pin 19. The movable pin 60 is integrally connected to a radially projecting guide rod 62, which is guided in a receptacle 63 and is biased by a spring means 64 in the direction of the rigid pin 19 away. The movable pin 60 protrudes with its upper end 65 slightly from the top of the mounting-side interface, said protruding end 65 serves as a handle for operating the mounting device. As in Fig. 8 are shown in the second embodiment, the holes 7 and 9 in the weapon-side member 1 and the heads 23 and 25 of the respective pins 19 and 21 in the attachment member side part 3 geometric as the holes 7 and 9 and heads 23 and 25 of the first embodiment is formed, in particular the head 25 of the movable pin 60 milled on its side facing the pin 19 side. In the second embodiment, for example, the head 25 of the movable pin 60 may be formed just like the head 23 of the rigid pin 19, ie as a circumferential truncated cone.

To insert the implement side member 3 in the weapon-side member 1, a user moves the handle 65 against the force of the spring means 64 in the direction of the rigid pin 19 and sets the two pins 19 and 60 in the corresponding holes 7 and 9 a. Then he lets go of the handle 65, whereby the pin 60 moves away from the fixed pin 19 by the spring force. In this case, the respective chamfers of the heads 23 and 25 run on the undercuts 15 of the bores 7 and 9 and attract the implement-side component 3 to the weapon-side member 1 at. At the same time, the two pins 19 and 60 also brace against each other under the undercuts 15. To open the mounting device, the user only needs the handle 65 again in the direction of the fixed pin 19 move, whereby the heads 23 and 25 come free from the undercuts 15, and then can remove the implement side member 3 from the weapon-side member 1.

The two mounting devices according to the first and the second embodiment basically have the same applications. However, since the spring means 64 is preferably dimensioned with a smaller spring force to still ensure easy manual opening of the handle 65, the second embodiment is preferably suitable for lighter attachment-side components 3. Alternatively, a lever mechanism could be provided for displacing the handle 65, whereby the spring means 64 can be more strongly dimensioned and the mounting device can also hold heavier attachment-side components 3.

Alternatively, the third embodiment may also be designed so that the movable pin 60 is biased in the direction of the rigid pin 19. For this purpose, the undercuts 15 of the bores 7 and 9 would have to face each other, or the holes 7 and 9 would each have two undercuts 15, as in FIGS. 7a and b shown.

In all embodiments, it may be advantageous to use the mounting device so that the rigid pin 19 is at a weapon behind, the movable pin 21 and 60 so front is in the weft direction and is tensioned to lock the mounting device in the direction of the rigid pin 19, the two holes 7 and 9 receiving weapon housing so charged to pressure. Thus, the locking spring 33 and 64 is not charged during a shot. For a higher ease of installation and greater freedom of design can further in the first embodiment, the handle 31 so from the locking mechanism 29 and 33 are decoupled that they no longer makes strokes.

Fig. 9 shows the integration of the holes 7 and 9 in a Picatinny rail 66; The Picatinny rail 66 thus assumes the function of the weapon-side component 1. For this purpose, the ribs 67 running transversely to the longitudinal direction of the Picatinny rail 66 and receiving the bores 7 and 9 are formed wider in the longitudinal direction of the rail 66. Of course, the broader training depends on the dimension of the holes 7 and 9 and the width of the ribs 67.

Fig. 10 shows the integration of a Picatinny rail 68 in the implement side member 3. As seen in this figure, the Picatinny rail 68 is fixedly connected via two spacers 69 to the implement side member 3 (preferably even integrally formed therewith) and runs parallel to it longitudinal direction.

Of course, the mounting device can be used according to the above embodiments for connecting two arbitrary functional components of a weapon including their accessories. For example, such a storm grip, a shoulder rest, an additional magazine, etc. are releasably connected to the weapon. In the in the Figures 9 and 10 shown embodiments may be provided as an alternative to the Picatinny rail 66 and 68, other common for weapons interfaces. It can also be mounted on a Picatinny rail 66 ( Fig. 9 ) are mounted on the mounting device another such conventional interface, instead of the Picatinny rail 68 (analogous to Fig. 10 ).
