Description

The invention relates to a fire selector unit for handguns that can be adapted for use on both sides, especially for firearms of the rifle type M4/M16/AR15, according to the preamble of claim 1. The invention also relates to a fire selector unit that can be operated from both sides. The invention and its variants are not limited to rifles, carbines, etc., but can in principle also be used for pistols. Some embodiments and their effects/advantages are given below.

Many rifles, particularly those based on or compatible with the AR15 platform, have a fire selector unit located in the lower case. The fire selector unit is usually constructed in one piece when used on one side and in several pieces when used on two sides, and is mounted on the right and left of the lower housing. The fire selector unit can be placed in predefined rotary positions in the lower housing, which correspond to either the trigger safety or one or more fire selector positions. The fire selector is held in the respective rotational position by a selector pin which is spring biased relative to the lower housing against the fire selector.

Assembly is normally accomplished by disassembling the rifle's grip and disengaging the selector pin from the through-hole for the fire selector unit. The fire selector unit can then be pushed sideways into the lower housing and is secured in the lower housing by mounting the selector pin or the handle. However, this process is relatively time-consuming and not very user-friendly.

In recent years, the need for good usability of the rifle that is individually tailored to the user has also become established in many places. Associated with this requirement is that the actuating element of the fire selector unit, which protrudes from the lower housing, should be easily accessible and operable. Thus it can be advantageous for the shooter if the fire selection unit is not only on the left side of the Lower housing, but instead or at the same time on the right side of the lower housing, can be actuated.

Some attempts have been made in the past which allow the fire selector unit to be operated from both sides. Examples of this are the US8276502B1 , US8549982B2 , US9557128B2 or the US9587897B1 named, the description of which is intended to be incorporated by reference as part of this disclosure - in the jurisdictions in which this is possible.

Using the example of US9557128B2 a reversibly usable fire selector unit is known, in which two shoulders are attached to a safety shaft for storage in the housing, each with a cam. However, disassembly of the handle is required to swap or flip the fire selector unit. In addition, securing by screws from the outside is relatively time-consuming and harbors the risk that these can come loose during operation.

From the US2020/0033088 A1 a similar fire selector unit is known, which is to be assembled from at least three parts, the central part, which carries a connecting link for the control, being inserted into the housing and then two end parts, at least one of which has an actuating member, plugged on and each secured by a locking pin be secured.

A number of multi-part fire selector units are thus known to the person skilled in the art, all of which require more or less difficult disassembly/assembly processes in order to enable simplified and/or double-sided operation.

In certain cases, however, it may be necessary to provide a fire selection unit that can be operated from both sides, such as in weapon exercises, training sessions, etc., which should be adapted to the shooter's needs again after the exercise. In a specific case, this can also mean that the shooter does not want to operate the fire selection unit on the right side after he has used a fire selection unit on both sides for practice purposes. Moreover, it may be desirable to choose between a fire selector unit with a selector angle range of 90° between the "safe position" (safe position) and a "fire position" (fire position) and a second fire selector unit with a smaller selector angle range. With the known fire selector units, conversion is extremely time-consuming and in some cases not possible without the appropriate tools. This means that an adaptation of the fire selection unit may not be possible in the operational area.

The object of the present invention is therefore to provide a fire selector unit that is easy to manufacture and operate, which enables disassembly and assembly without having to remove the selector pin and/or the grip of the rifle beforehand. A further task is to enable one-sided or two-sided operation if necessary without tools and to make the smallest possible number of components required. A further object of the invention is that the fire selector unit can be implemented in existing AR-15 housings with as little effort as possible. Another object is to offer a possibility for the simplest possible adaptation of the selector angle to the shooter's needs.

The fire selector unit according to the invention comprises a first fire selector lever with an integrally formed safety shaft, which is designed to be accommodated in a lower housing of the firearm and rotated into at least one fire selector position, the first fire selector lever having a first actuating element for actuation outside of the lower housing. Starting from the first actuating element and viewed in the direction of the opposite side of the weapon, the safety shaft has a first, essentially cylindrical bearing section, a selector section formed adjacent thereto and a connecting section adjacent thereto. In the area of the selector section, the safety shaft has one or more shoulders, which are referred to as selector surfaces for selecting a corresponding safety or firing position.

The above objects are achieved by the features specified in claim 1. In other words, the first fire selector lever has a bore in its longitudinal or bore direction, which is designed to complement the function and shape of a connecting unit. The connecting unit comprises a connecting element, a spring and a spring retainer and is designed to spring-biasedly couple a retaining element and/or a second fire selector lever formed integrally therewith. On the connecting portion of the first fire selector lever, viewed in the direction of the opposite side of the weapon, there is a positioning projection in the longitudinal direction educated. The connecting element has a complementary shape at its first end for coupling to the spring retainer and at its opposite second end for coupling to the securing element. The securing element has a substantially cylindrical bearing extension for mounting in the lower housing or, in one extreme case, can also consist solely of the bearing extension, or in the other extreme case, comprise an actuating element and thus be designed as a second fire selector lever. On the bearing extension, a primary control cam is formed in the circumferential direction for interaction with a selector pin arranged in the lower housing, which has a mounting groove directed towards the center plane of the weapon. In addition, the bearing extension has a coupling recess for receiving and supporting the second end of the connecting element and/or the positioning extension, which is open both in the radial direction to the outside and in the longitudinal direction to the outside.

The advantage of such a fire selector unit is the high degree of user-friendliness, since disassembly and assembly of the handle for installing or removing the fire selector unit is not necessary. The interaction of the connecting unit and safety element and the control cam arranged on it make it possible for the first fire selector lever to be inserted into the lower housing from the left and plugged into the safety element there by actuating the connecting element, the second end of which is simply deflected over the contour of the right side of the lower housing can be. The spring of the connection unit then ensures that the safety element is pulled towards the center of the weapon. The opening of the control curve in the form of the mounting groove makes it possible to reach the installation position without having to remove the selector pin and/or the handle. In addition, in the installed situation, due to the existing, spring-loaded coupling of the first fire selector lever to the securing element, only rotation of the fire selector unit in the circumferential direction is possible. In this way, the fire selector unit is positioned in the lower case and the risk of loss is significantly reduced.

Numerous other, partially preferred embodiments are explained below with reference to the description of the figures. In particular, different Opportunities received to achieve easier handling via locking extensions and / or the shape of individual components. In addition, the possibility of converting the fire selector unit to operation from both sides is discussed in particular, and individual suggestions are made for adjustments to the operation, such as setting the selector angle between the "safety position" and at least one "fire position". to optimize.

It is used throughout the description and the claims "in front" or "(after) the front" as the direction towards the muzzle of the barrel, "(after) the rear" as the direction towards the shaft, "(after) below" as the direction for the Closure towards the magazine - i.e. essentially downwards in the vertical direction - and "(upward)" as the direction away from the magazine - i.e. upwards in the vertical direction - is used. The designations "weapon center plane", "barrel", "barrel axis", "bore axis", etc. have the usual meaning that the person skilled in the art ascribes to them. "Left" is therefore related to the center plane of the weapon, "from the left" corresponds to a movement, actuation, exertion of force in the direction of the center plane of the weapon, starting from a starting position "to the left" of it, etc. Accordingly, the breech or the breech carrier is under the After a shot has been fired, it moves "backwards" under the action of the gases and "forwards" again under the action of a recoil spring, etc.

In the context of the invention there is disclosed, shown and described a fire selector unit suitable for placement in a firearm, preferably an AR-15 type rifle, designated "1".

In the figures of the drawings, an attempt was made to denote everything that relates to the first fire selector lever 11 with "1n", and analogously with "2n" for the safety element 2 according to the invention or the second fire selector lever 21, with "3n" for the connecting unit 3, " 4" for the lower housing, and "5n" for the reference to the fire selector lever 1 fixed coordinate system for orientation.

In 1 a fire selector unit 1 is shown in the schematic exploded view, comprising a first fire selector lever 11, a securing element 2 and a connecting unit 3. The first fire selector lever 11 has an actuating element 12, which in the installation situation (cf 10 ) comes to rest outside of the lower case 4. The fire selector lever 11 has a safety shaft 13, which is formed in one piece with the actuating element 12 and, starting from this, in the longitudinal direction 51, i.e. in the direction of the opposite side of the weapon (normal to the weapon center plane) in the installed situation, a bearing section 14 and a selector section 15 adjoining it having. At the selector section 15, a relatively short connecting section 16 is also arranged adjacent, of which a Positioning extension 18 in the longitudinal direction 51 protrudes. The connecting section 16 is preferably essentially ring-shaped and has the same (outer) diameter as the bearing section 14 . In this way, good guidance is ensured when inserting the first fire selector lever 11 into the lower housing 4 and good support of the fire selector unit 1 is made possible in the installation situation.

In 1 In addition, the connection unit 3 provided for coupling to the securing element 2 can be clearly seen, which has at least one connection element 31, a spring 36 and a spring retainer 37. A first end 32 for coupling to the spring retainer 37 or a second end 33 for coupling to the securing element 2 is formed on the connecting element 31 . For this purpose, the securing element 2 has a coupling recess 25 which is designed to complement the second end 33 in terms of shape and/or function. It is already clearly recognizable from this representation, especially in combination with the Figures 9a to 10b that the connecting element 31 in the installation situation in the longitudinal direction 51 relative to the first fire selector lever 11 in an axial or parallel bore 17 of the fire selector lever ( 7 ) can be relocated. The bore 17 is designed to be complementary in shape to the components of the connection unit 3 . The bore 17 is preferably designed as a stepped bore. The (internal) diameters of the respective stages essentially correspond to the diameters of the connecting element 31, the spring 36 and the spring retainer 37, as can be seen from the combination with FIG Figure 9a and 9b is clearly recognizable. However, a step in the bore 17 as a one-sided abutment for the spring 36 would already be sufficient to ensure the function of the fire selector unit 1.

In Fig. 2a-c Various exemplary embodiments for a securing element 2 are shown schematically, for which the coordinate system is also shown 1 is to be applied. What they all have in common is that the securing element 2 has a bearing extension 24 which is used for bearing in the lower housing 4 . This bearing extension 24 preferably has the same diameter as the bearing section 14 of the first fire selector lever 11. In addition, all exemplary embodiments have a coupling recess 25 which is open in the longitudinal direction 51 and on at least one side in the radial direction 52. In this way, the second end 33 of the connecting element 31 can be laterally, i.e. in radial direction 52, if it was deflected far enough out of the first fire selector lever 11, as will be explained later (see also 9 ). In Figure 2a the simplest variant of the securing element 2 is outlined, after which the securing element 2 consists only of the bearing extension 24 . In this form, the securing element 2 forms a kind of (rotatable) “blind plug” on the right-hand side of the lower housing 4 in the installed situation. This creates a unit that can be operated from one side. In one embodiment, the securing element 2 can have a projection or also a flange-like shoulder which comes to rest on the outside of the lower housing 4 . In Figures 2b and 2c exemplary embodiments are each shown which have a second actuating element 22 which is formed on the securing element 2 . In this way, a second fire selector lever 21 is formed, with which the fire selector unit 1 can be operated on both sides of the lower housing 4.

The different length of the actuating elements 22 in Figures 2b and 2c are intended to represent that the invention can have a variety of shapes, lengths, surface structures, colors, etc. of the first 11 and/or second fire selector lever 21, or the sole safety element 2, which can be freely combined with one another. The possible configurations and combinations are not discussed in detail since, knowing the invention, it is at the discretion of the person skilled in the art to optimally adapt the invention to the needs of the shooter.

In synopsis 1 and 2a to 2c a preferred embodiment can also be seen, according to which the second end 33 of the connecting element 31 has at least one snap-in projection 35 which is designed to project outwards normal to the longitudinal direction 51 for coupling to the coupling recess 25 of the securing element 2 . A rounded second end 33 of the connecting element 31 would already be sufficient for coupling to the securing element 2 . However, it has been shown that it is advantageous if one or, particularly preferably, two diametrically opposite latching projections 35, as in 1 , 3 and 8 and 9 clearly recognizable, are formed at the second end 33. In this way, the orientation of the latching extension(s) 35 can fulfill an additional function, which represents a type of anti-twist protection and reduces the risk of decoupling in use, such as from vibration.

In a further preferred variant of the invention, the second end 33 of the connecting element 31 and/or the spring retainer 37 has a non-circular, elliptical, oval or multi-sided, preferably rectangular, shape. The decisive factor here is that a round head of the second end 33, as noted above, would already provide the coupling to the securing element 2, but the risk of rotation in the circumferential direction 53 of the connecting element 31 can be decisively reduced by the choice of the shape of the second end 33 . An independent or additional measure can be that the spring retainer 37 has a non-round shape. As in the figures 1 and 7 The spring retainer 37 clearly has an elliptical (or two semicircles with a straight connection) shape, which prevents twisting in the bore 17 of the first fire selector lever 11 of complementary shape. Analogous to this, multi-sided polygon shapes or even a triangular shape fulfill the same anti-twist protection function.

A particular aspect of the invention relates to the arrangement and design of a control cam 241 on the bearing extension 24 of the securing element 2. The fact that the spring-loaded selector pin--not shown but well known to those skilled in the art--is positioned diagonally from below in the lower housing 4 ( figs 8th , 9) protrudes into the transverse opening for receiving the fire selector unit 1, the inventive separation of the first fire selector lever 11 and the safety element 2, or a second fire selector lever 21, in the manner described is very advantageous. In figs 3a to 3c are corresponding oblique views to those in figs 2a to 2c shown fuse elements 2 and second fire selector levers 21 in a different perspective. It is clearly evident here that the primary cam 241 is formed in the circumferential direction 53 on the circumference of the bearing extension 24 . The primary cam 241 is longitudinally 51, see 1 , i.e. in the direction of the opposite side of the weapon, open in the installation situation. This opening can be designed as a V, U or rectangular recess and is referred to as the mounting groove 242 . This has the previously described effect that the first fire selector lever 11 can be inserted during assembly of the device without being blocked by the selector pin to become. The securing element 2 can be pulled laterally into the lower housing 4 through the mounting groove 242 , which takes place in the correct position due to the coupling with the connecting element 31 , and the selector pin can engage in the primary cam 241 . A removal of the selector pin is avoided in this way, whereby the user-friendliness and suitability for use of the fire selector unit 1 according to the invention is increased compared to known arrangements.

In addition, 3 It is clearly evident in all exemplary embodiments that the primary control cam 241 has two (radial) selector depressions 243 to define the end position or limit the movement of the selector pin and thus the rotation of the fire selector unit 1 in the circumferential direction 53 . These act as a kind of detent for the selector pin and are known per se to those skilled in the art.

Another aspect of the invention is also from Figures 1 to 5 and 7 to 10 clearly visible, after which a positioning extension 18 is formed in the longitudinal direction 51 on the connecting section 16 protruding. This positioning extension 18 is used to transmit torque or force from the first and/or second fire selector lever 11 (or 21) to the entire fire selector unit 1. It has proven to be advantageous to design the positioning extension 18 to complement the coupling recess 25 in order to provide a good contact surface and get power transmission. Mutatis mutandis, it can represent a preferred measure to form one (or more) locking surface 26 on the coupling recess 25 of the securing element 2 that is complementary in shape to the second end 33 of the connecting element 31 and/or the positioning extension 18 . This connection is also the synopsis with 2 very clearly visible.

A further, possibly independent measure for optimizing the torque or force transmission when the first and/or second fire selector lever 11 (or 21) is actuated can consist in the second end 33 of the connecting element 31 having a flattened area 34 that is complementary in shape to the blocking surface 26. In the selected representations, this embodiment is taken into account and very well in the figs 1 , 7 and 9 apparent. This is particularly advantageous when the dimensions of the positioning extension 18 and the second end 33 are aligned in the radial direction 52 are formed, so a form-fitting connection is formed, whereby a simple installation of the fire selector unit 1 is favored.

For an understanding of the assembly of the fire selector unit 1 is at this point on a synopsis of the figures, in particular figs 1 , 7 , 8a and 8b, 9a and 9b , and 10a and 10. First, although not shown in detail, the connecting element 31 is inserted into the bore 17 of the first fire selector lever 11, after which the spring 36 is inserted into the bore 17 and the first end 32 is coupled to the spring retainer 37. The spring retainer 37 can be embodied as a type of small plate, for example, and can have one or more detents, with the first end 32 having corresponding detent notches for the purpose of coupling. A person skilled in the art is aware of numerous possibilities for coupling the two elements, such as a snap-in or plug-in connection, but in particular the possibility of a screw connection from the prior art. How particularly good from a synopsis of 7 and Figure 9a conceivable, the coupling of the first end 32 to the spring retainer 37 can be carried out by relatively simply screwing in the connecting element 31 . If the connection unit 3, as in Figures 8a and 9a , or. Figure 10a brought into the disassembling/assembling position by pressure on the spring retainer 37 side, the second end 33 of the connecting element 31 is deflected via the connecting section 16 and also protrudes from the lower housing 4 . The lower case 4 is in the Figures 8 and 9 indicated as a hatched area. Thereafter, the securing element 2 or the second fire selector lever 21 can simply be pushed on and the fire selector unit 1 is pulled into the installation situation by the spring force of the spring 36 and held there during operation.

The possible embodiments described above make it possible in a relatively simple manner to provide a fire selector unit 1 that is very user-friendly to disassemble/assemble and also only requires a makeshift tool, such as a cartridge tip or a pen, to close the connecting element 31 actuate. In the installation situation, however, the spring retainer 37 can end flush with the first actuating element 11 on the outside, or even be set back behind the surface. This reduces the risk of a accidental adjustment is significantly minimized. In particular, the aforementioned individual measures or their combination can permanently ensure the position of the connection unit 3 in the operating state without there being any risk of the coupling to the securing element 2 being released automatically.

At this point it is explicitly pointed out that the fire selection unit according to the invention is also particularly suitable for optimizing the selector angle 23 . This connection works very well figs 4 out, in which in Figure 4a an exemplary second fire selector lever 21 is shown with a cam 241, which occupies a selector angle of 90°. This can be clearly seen from the corresponding sectional view of the sectional plane AA' in the lower half of the figure. In Figure 4b a second fire selector lever 21 is shown with a primary control cam 241, the selector angle 23 of which is formed in an angular range of less than 90°, see sectional view BB'. By simply exchanging a second fire selector lever 21 or a corresponding safety element 2 with a correspondingly desired selector angle 23, the shooter can adjust the fire selector position in a relatively simple manner. Moreover, it is therefore relatively easy to convert the fire selector unit 1 that can be operated from one side to a fire selector unit 1 that can be operated from both sides.

In addition, it can be advantageous if the user is given the opportunity to provide two different control curves, ie a primary 241 and a secondary control curve 141, on a fire selector unit 1 . This situation is, for example, in Figure 5b 1, wherein a secondary cam 141 is formed on bearing portion 14. Likewise, this is in the figures 7 , 8th and 10 shown schematically. The designation and design of the mounting groove 242 and the selector recesses 243 remain unchanged, since it is up to the person skilled in the art to optimize their number, size, shape and arrangement with knowledge of the invention and in view of the respective application requirements. However, it should be noted that the design of the securing shaft 13, more precisely the selector section 15, is related to the design of the primary and/or secondary cam 241, 141.

This is evident from the exemplary sectional views in Figures 6a to 6c emerges that, purely schematically, different situations on the level CC' in Figure 5a to express. In figs 6a to 6c each selector sections 15 are shown, which have an acentric bore 17 and a securing surface 153 and at least one primary selector surface 151. In a generally known manner, the safety surface 153 represents the lateral surface along the circumference of the selector section 15, or at least part of it, and serves to block the trigger in the “safe position”.

in the in figure 5 indicated position, the primary selector surface 151 is set to active, i.e. the rifle is in a ready-to-fire state, since the selector surfaces 151 in Figures 6a to 6c represent a level recess in relation to the safety surface 153, as a result of which the trigger can be further deflected ("fire position").

In Figure 6a a section through a selector section 15 is shown, which represents the most common variant of a safety shaft 13, which only allows a "safe position" and a "fire position". The corresponding primary cam 241 must therefore have a selector angle 23 of approximately 90° in order to interact correctly with this type of selector section 15, which is sufficiently well known to those skilled in the art without further explanation.

A slightly different situation can be achieved with a selector section 15 as shown in Figure 6b is shown. Here, when using the primary cam 241 on the securing element 2, there is a situation analogous to that of FIG Figure 6a only one way to set the "fire position". In a preferred embodiment, the selector section 15 has an additional, secondary selector surface 152 . The formation of the second selector surface 152 on the selector section 15 makes it possible, in conjunction with the present invention, to adjust the selector angle 23 of the primary cam 241 . For example, by replacing the safety element 2 or the second fire selector lever 21, a second selector angle 23a can be obtained which is not equal to the original selector angle 23. In most cases, the selector angle 23 is 90° in the “standard configuration”, it being advantageous for a second selector angle 23a to be less than 90°, preferably im Angular range from 40° to 80°, to be provided for the operation of the rifle, for example in competitions or in tactical use, in order to achieve a shorter actuation path when setting the fire selector unit 1.

In a further preferred embodiment ( figs 5-7 ) the bearing section 14 of the first fire selector lever 11 has a secondary control cam 141 in the circumferential direction 53 with a control cam opening 242 directed towards the center plane of the weapon. It is advantageous here for the selector section 15 to have an additional, secondary selector surface 152, as is shown, for example, in Figure 6c is evident. Such a constellation now offers the possibility of adjusting the selector angle 23 without having to replace or exchange the second fire selector lever 21 . If the primary control cam 241 is designed with a selector angle 23 of 90° and the secondary control cam 141 with a selector angle 23a of less than 90°, then by converting the first fire selector lever 11 to the right side of the weapon and coupling the second fire selector lever 21 to the left side of the weapon a relatively simple adjustment of the selector angle 23 can be made. In an advantageous embodiment, the secondary cam 141 is therefore shorter in the circumferential direction 53 than the primary cam 241, preferably extending over a second selector angle 23a of 40° to 80°, particularly preferably of about 55°.

The advantage of this embodiment according to the invention, specifically enabling adjustment of the actuation path or the selector angle 23 by simply reversing the insertion direction of the fire selector unit 1 , is made possible by the positioning extension 18 of the first fire selector lever 11 . When inserting from the “right”, this positioning extension 18 serves to deflect the spring-loaded selector pin in the lower housing 4, thus making insertion—without removing the selector pin—possible in the first place. When it reaches the opposite left-hand side of the lower housing 4, the bearing section 14 moves into the specified position on the right-hand side of the lower housing 4 without being blocked, since the secondary cam 141 also has a mounting groove 242 open to the opposite side of the weapon, and the selector pin can therefore enter the cam 141 unhindered lets occur. This connection can easily be illustrated using the Figures 8 to 10 comprehend.

In a special embodiment, a closure extension 19 is formed on the connecting element 16, which primarily serves to close the assembly groove 242 of the primary cam 241 in the installation situation in the direction of the weapon center plane. In this way, additional protection is provided against the ingress of any dust and/or other foreign bodies. This closure extension 19 can also fulfill a function as a positioning aid during insertion and also acts as an additional support in the radial direction when installed. In this way, the transmission of force or torque when the fire selector unit 1 is actuated can be improved, in particular when a second fire selector lever 21 is used.

Additional positioning aids can also be provided, such as in figure 5 a and 5b on the positioning extension 18 a further gradation can be seen. If a corresponding counterpart is provided on the securing element 2, as is shown in 2 As can be seen quite well from the perspective, such a positioning aid can certainly also contribute to passing on the forces or the torque when the fire selector unit 1 is actuated. Such positioning aid pairings can be designed as extensions and corresponding recesses, but also, for example, as detents with beveled surfaces. Due to the brevity of the present description and the clarity of the illustration, separate reference numbers are omitted.

It is clear to the person skilled in the art that the illustrated embodiments were selected as schematic and/or exemplary representations and that it is possible for the person skilled in the art to transfer the relationships according to the invention to embodiments that are not explicitly shown without any problems, which is why these implicitly disclosed embodiments are included both in the description of the figures and can also be silently read in the claims.
