Description

Mounting rail for firearm

The invention relates to the mechanical detachable connection between a firearm, in particular a pistol, and an accessory such as a lamp, a laser Zielvor- direction, a compensator, a muffler or other, to be attached to the weapon device.

In the prior art, for the quick, easy and reliable assembly / disassembly of such accessories to the gun, guides in the form of rails are proposed which are substantially parallel to the barrel, as for example in GB 3027 A of 1915, US 4,944,213 A 1990, the so-called "Swan rail" described in US 5,142,806 A, the very similar "weaver rail" for which no patent literature could be found and finally the rail, as in the US 6,574,901 B from 2003 is known. The content of said documents and the inventor's US 4,539,889 A, from which an example of the overall construction of a modern pistol is known, is incorporated by reference into the subject of the present application.

The oldest of the compounds mentioned allows the attachment of a search telescope obliquely above the barrel of a rifle to shoot if necessary without the use of the still mounted search scope over the sight and grain. It is, in order to achieve this, the serious eccentricity of the weight distribution accepted and also that the shooter when using the riflescope must hold the weapon in a manner not familiar to him.

The Weaver and Swan rails are primarily for rifles, carabiners and semi-automatic or automatic weapons and are mounted above the barrel or above the closure and often carry the target devices, since they or mounted on them attachments on the weapon itself intended target devices would usually obscure.

For handguns, especially pistols, the assembly has below the barrel in front of the trigger (trigger), especially in front of the guard (trigger guard), the ignition gel surrounds, enforced. In this case, the fastening rail can be part of the weapon or attached as a separate part fitting to the weapon.

The objects to be mounted on the rail have fastening devices which are geometrically designed such that they allow sliding on the rail and locking, usually also on the rail. In particular, this interaction is well visible from US 6,574,901 B.

The previously known fastening rails essentially fulfill the tasks assigned to them, in particular the fixed mechanical connection, which nevertheless is easily detachable, satisfactorily, but it has been found that the relative position, in particular the parallelism between the rail axis and the running axis, is reduced the delivery of a few shots in a short time interval and even already due to thermal changes, as they occur when leaving an air-conditioned building in the summer, when leaving a heated motor vehicle in winter, etc., drastically changes and in particular the use of a laser pointer as a target mark completely obsolete leaves.

Other fasteners are also known for attaching attachments to weapons, especially handguns. For example, US Pat. No. 5,282,594 A, US Pat. No. 5,581,898 A, WO 03/089868 A and AT 412 914 B disclose additional devices by means of clamping devices Mount trigger guard. All these devices have the disadvantage that the assembly or disassembly tool is required that the adjustment is difficult and that the mechanical stability and thus the durability of the accuracy of the assembly are very low.

Finally, it is known from US Pat. No. 5,758,448 A to fasten a mounting part at the front, substantially normal to the running axis portion of a trigger guard, whose end face carries a vertically extending, undercut guide. On this guide then different accessories can be postponed, without it being necessary to take the mounting part of the weapon. This represents a significant improvement in ease of use compared to the previous proposals, the structure of the mounting device and the far before the trigger guard, still This very narrow guide entail that the mechanical stability and thus the accuracy of the course of the leadership, in turn, the mounting accuracy and strength of the connection is extremely poor.

It is an object of the invention to avoid all these problems and to provide a fixture for an additional device to a weapon, in particular a gun, in which, while maintaining the advantages of the prior art devices, the disadvantages mentioned do not occur.

According to the invention, these goals are achieved in that the rail is formed or attached to the trigger guard. The trigger guard consists in almost all firearms essentially of three sections, one of which, the lower, usually parallel or substantially parallel to the barrel axis and another, the front, either substantially normal to the barrel axis or substantially parallel to the magazine axis or oriented generally obliquely to the running axis, wherein these two portions are connected by a connecting portion. The connecting portion is square or round in side view, the two other sections are substantially straight.

A rail is now inventively formed at the front and / or at the lower portion of the trigger guard and thus disturbs neither the shooter in the handling of the weapon still makes them a relearning because of a changed center of gravity of the weapon or because of a changed arrangement of the accessories necessary. It is more comfortable and safer to handle, in particular for non-professional users of the weapon, to attach an attachment to the weapon as the user is accustomed to inserting the magazine, i. not before the mouth of the barrel, but below the barrel to handle. The assembly at the bottom, directed substantially parallel to the barrel axis portion of the trigger guard is easily possible.

The invention will be explained in more detail below with reference to the drawing. 1 to 5 show a first embodiment of the invention, FIGS. 6 to 14 show a second embodiment of the invention and FIGS. 15 to 18 show a variant of a lock. - A -

A first embodiment of the invention can be seen from FIGS. 1-5, in which the rail is arranged, namely formed, at the lower, at least approximately parallel, section of the trigger guard running parallel to the running axis. 1 shows a side view of the part of a weapon, around a trigger guard, FIG. 2 shows the position between the weapon and an accessory immediately before pushing on, FIG. 3 shows the situation of FIG. 2 in FIG perspective view, Fig. 4 shows a side view of the situation after the successful sliding of the accessories and Fig. 5 shows the situation of Fig. 4 in a front view.

In principle, it should be noted to all representations that only the part of the weapon is shown, which is essential for the invention, thus the part around the trigger guard. The handle, the magazine guide, the trigger mechanism, the carriage and the barrel, as well as large parts of the housing, can be designed in many different ways, without this having a special influence on the invention. For this reason, these parts of the weapon as well as the trigger itself are not shown in order not to overload the drawings and to make it clear that the invention can be applied to a variety of firearms, if they have only a trigger guard. Reference is made in this regard to the prior art incorporated by reference into the application.

Fig. 1 shows the part of a pistol which is formed around a trigger guard 2 of this weapon 1. This part of the weapon 1 has guides for the carriage of the gun and in practice, of course, also on a trigger, not shown here. Shown is also a guide 3 parallel to the run, not shown, on the front part of the housing. This guide 3 corresponds to the rails mentioned in the introduction to the description and the presence of such a rail does not adversely affect the provision of a rail according to the invention, as will be apparent from the following description.

According to the invention is in the lower part 4 of the trigger guard, which runs at least substantially parallel to the axis, whose direction is again indicated by the dot-dash line 5, which is parallel to the barrel axis, a rail 6, also called mounting rail provided. The rail 6 consists in the illustrated embodiment of two strip-like projections which are arranged symmetrically to the weapon center plane on the trigger guard 2 and preferably in the front region, from which the pushing of an accessory follows, are tapered, since they have chamfers 7 through which the sliding of the accessories are facilitated.

In the illustrated embodiment, a light module has been selected as an accessory 8, this has a substantially adapted to the outline of the weapon outer shape to the formation of projections, edges, corners, columns udgl. to avoid, because such disturbances of a smooth as possible continuous contour in use can be uncomfortable and even dangerous, but this is not generally necessary for the invention itself, but for the weapon.

Of importance for the functioning of the invention is that the accessory 8 has a receptacle 9, whose inner contour is formed to match the outer contour of the rail 6. In the illustrated embodiment, to further facilitate the placement of the accessory 8, the inner contour of the receptacle 9 in the end region 10 is enlarged or extended, so that the placement before pushing in the direction of the arrow 11 can take place without requiring the user too great accuracy which is advantageous for use in the field.

The sliding of the accessory 8 on the rail 6 leads to the situation shown in Fig. 4. A locking of the mounted accessory (not shown) can be done for example by a resilient tongue in the end portion 10 of the receptacle 9, which cooperates with a recess or recess in the magazine-side region of the rail 6. The locking can take place in a force-locking manner, that is, be released by sufficiently large force in the direction against the arrow 11 by elastic deformation, or positively, wherein a mechanism for releasing the connection, as described further below, must be provided. In the illustrated embodiment, such a mechanism may consist of a part of the trigger guard, which is pressed from the inside into the recess and thus presses the resilient tongue out of the recess. Due to the appropriate shaping of the accessory 8 on the side facing the barrel, a support of the accessory in the front (mouth-side) region of the housing of the weapon 1 can be made, if desired. Because of the problems mentioned above, this is not advantageous in the case of laser pointers, but in the case of lamps, compensators, etc., in which the mechanical stability is important, but the accuracy of the positioning is secondary.

Figs. 6-14 show a second embodiment of the invention, in the description the same reference numerals will be used for the same parts as in the first embodiment, analogous parts will be given a reference number increased by 10.

Fig. 6 shows in a view similar to Fig. 1, the arrangement of the rail 16 on the trigger guard 2: In this embodiment, the rail 16 is substantially perpendicular (perpendicular) to the barrel axis 5 (Fig. 7), but is otherwise formed similar to in the first embodiment, namely by strip-shaped projections on both sides of the front portion 12 of the trigger guard 2. It is of course not necessary that the rail 16 is oriented normal to the barrel axis 5, it is of course possible to adapt their orientation to the structure of the weapon, For example, the rail 16 (and thus this portion of the trigger guard) to run parallel to the axis of the magazine, which may bring advantages in the manufacture of the housing of the weapon 1 with it; is essential and in the knowledge of the invention is of course only that the arrangement and orientation of the associated receptacle 19 on the accessory 8 is arranged and provided accordingly.

The rail 16 has at its free end to which the accessory 8 is attached, a taper 7, analogously, the receptacle 19 has a widening 10 at the weapon 1 facing the end, whereby the attachment of the accessory 8 facilitates during assembly is, the assembly / disassembly takes place in the direction of the double arrow 21st

In this embodiment, a preferred fixation of the accessory 8 to the weapon 1 is described in more detail: The accessory 8 has a handle 13 which can be moved in the directions corresponding to the double arrow 14 (FIG. 10). Furthermore, the accessory 8 has a clockwise loaded under the force of a spring, not shown Pivoting lever 15, which is pivotable about a normal (perpendicular) to the weapon center plane (plane of Fig. 10) oriented axis 17 and so also the handle 13 to the barrel out (upward) urges.

In the situation shown in Fig. 10, in which the accessory 8 is pushed onto the weapon 1 and locked by the pivot lever 15, the pivot lever 15 rests with an end face 18 on a mating surface 22 of the trigger guard 2, thus preventing the accessory 8 from the weapon 1 slides. In order to remove the accessory 8 from the weapon 1, the user must move the handle 13 away from the barrel (downwards) in the direction of the double arrow 14, whereby the pivot lever 15 cooperates with a cam surface 20 which cooperates with the contour of the handle 13 , is pivoted against the force of the spring, so that its end face 18 comes out of the region of the counter surface 22 and the accessory 8 is displaced along the rail 16, thus can be removed.

This embodiment can be replaced by other fixings, but has the advantage that the user to remove the accessory without grasping or using the second hand, which anyway must hold the weapon 1, by releasing the handle in the desired direction of removal both unlocks triggers as the accessories of the weapon decreases. When sliding the accessory of the pivot lever 15 pivots automatically by sliding on the rail 16, as well as automatically engages the pivot lever after complete pushing with its end face 18 on the counter surface 22, since it is under the action of the spring, not shown. Another pivoting is prevented by the front of the trigger guard 2 (no reference numeral). Of course, it is possible to form the pivoting lever differently, it can also be resilient in itself and then does not require a separate spring.

FIGS. 15-18 show a lock for a connection to a rail 6 according to the first embodiment of the invention. It consists of at least one locking surface 23 on the trigger guard 2 and an associated locking claw 24 on the accessory 8. Of course, two such elements are provided for reasons of symmetry in the illustrated embodiment. The locking claws 24 are pivotally mounted about substantially normal to the axis 5 and parallel to the central plane of the weapon (plane in Fig. 17) extending axes of rotation 25 and are of a spring (not shown) urged into the locking position shown in Fig. 18, are in the hook 27 behind the locking surface 23 on the trigger guard 2 and so secure the accessories. Pressure surfaces 26 of the locking claws 24 protrude slightly in this position over the outer surface of the accessory 8 and can be pressed by the user against the force of the spring inside, causing the locking claws to pivot about their axes of rotation 25 so far that the hook 27 of the locking surfaces 23rd get free and pull off the accessories 8 to the front.

When mounting the hooks 27 run on the locking surfaces 23 and are pivoted by them against the force of the spring until they hook behind the locking surfaces, thus causing the lock. Of course, a separate spring can be provided for each locking claw 24 and the position and arrangement of the rotary axes 25 can be selected differently than illustrated. It is essential for the user that when removing the accessory during actuation of the lock, he can also perform the removal movement without having to reach around and that the attachment of the accessory takes place without having to operate the lock extra.

As materials all materials used in the field of weapon production can be used. In today's many common cases for weapons made of plastic, the rails 6, 16 made of this plastic can be made in one piece with the housing of the weapon, so the representation of the individual figures would read. Of course, it is possible to manufacture the rail or parts of the rail made of metal and insert in weapons casings made of plastic as a lost core in the production of the mold, so that a reliable and mechanically stable connection of rail and trigger guard is achieved. On the other hand, it is also possible to form the rail of plastic and to increase the mechanical stability of the trigger guard this with a metal insert, under certain circumstances, this metal insert to further increase the mechanical strength in one piece with a guide made of metal for the carriage in the upper area be formed of the housing 1.

On other aspects of the invention, such as a resilient support of the accessories on the underside of the housing of the weapon in the front area between the trigger guard and muzzle must not be discussed here. Even the shape of the accessories can be different than in the illustrated embodiments, it is only essential that the inclusion of accessories with the rail on the weapon is fitting and correct position to make sure that the orientation of the accessory and its location relative to the barrel reliably the desired predetermined position equivalent.

Finally, it is purely a matter of definition whether one refers to the receptacle 9, 19 as a receptacle or as a "counter-rail", recess or whatever .It also does not matter for the invention if, instead of the strip-like projections, the rail 6 16, grooves are provided on the rails which cooperate with complementary projections in the receptacles, but the variant shown is preferred because of the better mechanical stability.

If, as in the embodiment according to FIGS. 1-5 in the region of the barrel of the weapon a prior art guide 3 is provided, if this guide is parallel to the rail 6, a double attachment of the accessory 8 can be provided simultaneously on both elements. Here, too, the unpleasant dislocation that may occur is to be weighed against the advantages of mechanical stiffening.

It is also possible to provide the rail below or in front of the respective section of the drawbar, but then it comes to the formation of depressions at the transition from the trigger guard to the rail, which is not advantageous both mechanically and for cleaning, so this solution probably only in special cases can be used.

If the rail (s) are not integrally formed with the trigger guard (which is preferred), but are arranged on a separate mounting part, it is advantageous that the rail consists of strips, which are arranged on the left and right of the trigger guard. As a result, the geometry is much more resistant, since larger lever arms for transmitting attacking torques and slate loads available as narrow guides. Furthermore, it is advantageous in this case, when the mounting part is glued to the trigger guard. This achieves a mechanically strong and reliable connection, which maintains its positional accuracy for a long time. Of course, advantageous is the formation of the rail from or on the trigger guard in the manufacture of the weapon. Even if a reinforcement inside the trigger guard is present, the training in the description and claims is referred to in this case as "one piece".
