EP4001823B1 - Multifunction cover plate - Google Patents

Description

The invention relates to a multi-function cover plate for the carriage of a pistol, and to a pistol having such a multi-function cover plate, according to the preamble of claim 1 and those discussed further below U.S. 2013/0000173 A1 .

In general, for the function of handguns, especially pistols, it can be stated that after a cartridge has been fired, the empty cartridge case must be removed from the cartridge chamber of the handgun as reliably as possible before a new cartridge can be fed in during the reloading process.

This usually results in a breech movement, e.g. the slide of a pistol moves backwards and - depending on the pistol model - can also be accompanied by a tilting movement of the barrel. During this linear movement of the carriage, the cartridge case is pulled out of the cartridge chamber, among other things, and the cartridge or case ejection process is completed. Likewise, in the course of this process, the trigger or a trigger device can be cocked, and a reloading process can take place in order to be able to fire a cartridge again. Such trigger devices very often comprise a large number of components and are preferably arranged in the handle of the pistol. During the movement of the slide, certain subassemblies arranged in the pistol grip, such as the trigger device, can interact with subassemblies arranged in the pistol slide, such as a firing pin device. Assemblies such as the firing pin device, the extractor unit and/or fuses are therefore often arranged in the carriage. The respective processes and manufacturer-related peculiarities of the individual assemblies are well known to the person skilled in the art and therefore do not require any further explanation at this point.

With the introduction of the GLOCK ^® pistols in the 1980s, a concept became widespread in pistols, in which the firing pin device is arranged in the slide. The slide is usually closed at the back, i.e. in the direction facing the shooter, by means of a cover plate in such a way that the Firing pin device or an extractor unit in the slide is secured against falling out. For example, such cover plates in the US9664471B1 , the US10139174B2 or that WO 2020157528 A1 described.

It is also known to modify the top plate in such a way that it is designed for easier actuation of the carriage movement during manual loading. This is in the U.S. 2011/154710 A1 disclosed where lateral "wings" are evident.

In the U.S. 2013/0000173 A1 a multi-part cover plate is presented which essentially acts as an additional safety device with the firing pin unit or the trigger unit of a pistol. This safety device has an extension on the cover plate, or on a movable part connected to the cover plate, which can be activated by pressing the thumb, for example to block the firing pin device so that a shot can be prevented.

To enable the pistol to be roughly dismantled, the slide can be separated from the grip. Very often, the slide and handle are connected to one another via guide elements and guide rails of complementary shape and can be pushed apart after unlocking. As a rule, the slide can be pulled forwards, i.e. in the direction of travel, from the pistol grip.

Very often, however, individual components which are arranged in the grip, such as an ejector and/or a control spring, and which interact with the cartridge and/or assemblies arranged in the slide, such as the firing pin device, for the function of the pistol, are in the movement path of the sleds. For this reason, the prior art mostly includes cover plates which have one or more recesses. These recesses are usually designed in such a way as to release the components protruding from the grip in the vertical direction and to enable the carriage to be pulled off. The cover plates are often designed in the vertical direction in such a way that the guide rail of the carriage remains free so that the guide elements do not close when the carriage is removed To block. These relationships are known to the person skilled in the art and therefore do not have to be explained further in detail.

Furthermore, a connection between the interior of the pistol and the environment is formed by means of a gap between the carriage and the grip and recesses provided on the back of the carriage.

In addition to contributing to the dismantling of the pistol, the recesses can also serve, among other things, to ensure that, for example in a maritime environment or when the pistol is used after a dive, the water from inside the pistol can escape to the outside more easily. However, in a few areas of application, such as in desert areas, dust and/or sand may get on the pistol.

In order to enable low-friction movement processes during operation of the gun, however, it is desirable to reduce or at best completely avoid the penetration of foreign bodies, such as sand, dust, mud and the like, into the interior of the gun.

It is therefore an object of the present invention to provide a cover plate for the slide of a pistol, which shields the interior of the pistol from the outside as far as possible. A further object of the invention is to make the pistol easier to operate, in particular with regard to dismantling and/or actuating the slide during the loading process.

These tasks are solved by a multifunction cover plate according to claim 11. In other words, the cover plate according to the invention, also called a multifunctional cover plate, comprises a base part, also called a base plate, which is designed for insertion into a cover plate receptacle provided for this purpose on the carriage and a cover plate that is movable relative to this base plate. This cover plate is designed to be movable between an open position, in which the path of movement of the carriage is released for removal from the grip, and a closed position, in which the carriage is outwardly closed on its rear side facing the shooter.

The design of the cover plate according to the invention, which in the closed position largely conceals the slide to the outside, can reduce the undesirable ingress of foreign bodies. The cover plate is advantageously in the closed position when the pistol is at rest, as well as when the pistol is being fired, and is only moved to the open position for disassembly of the pistol.

The base plate of the multifunction cover plate can have one or more recesses which allow the carriage to be removed in the manner described above. Furthermore, the base part can be designed to support the firing pin device and/or an extractor unit. It is also possible one Reinforcement plate, often referred to as a circuit board, to be provided on or within the base part.

The cover plate of the multifunction cover plate can be designed to be displaceable and/or pivotable relative to the base plate. Accordingly, to put it simply, the cover plate can be designed as a type of flap or also as a slide.

It has proven to be advantageous if at least one latching connection is provided on the base plate and/or the cover plate in order to enable the cover plate to be temporarily fixed in the open position and/or the closed position. In this way, for example, the risk of an undesired adjustment of the cover plate to the open position during operation can be reduced. Mutatis mutandis is the case when disassembling or assembling the pistol, with the cover plate remaining in the open position by itself.

Furthermore, it can be expedient to form this latching connection by preferably elastic latching projections and correspondingly arranged latching notches. In a preferred embodiment, at least one latching extension is formed on the base plate and at least one latching notch is formed on the cover plate, elements of the latching connection that are arranged in reverse are also expressly included in the present disclosure.

In addition, it can be provided that a spring mechanism is designed to apply a prestress to the cover plate in the direction of the closed position. In this way, the cover plate can, in the best case, be automatically brought into the closed position and the risk of it opening undesirably can be reduced. The spring mechanism can be arranged both in the base plate and/or the cover plate.

The spring mechanism can be constructed in several parts, ie, for example, it can comprise several helical or leaf springs and/or holders. In some embodiments it may be advantageous to form the spring of the spring mechanism in one piece, ie integrally, on one of the components of the multifunction cover plate.

According to a development, it is possible for a flattened area to be formed on the base plate and/or the cover plate to interact with the spring mechanism or to apply the prestress. Such a flattening can improve the contact with a spring, in particular a leaf spring, and act like a kind of latching connection.

Furthermore, it can be expedient for the spring mechanism to comprise a leaf spring. In a particularly preferred embodiment, the spring mechanism may be formed integrally with the base, such as in the form of a leaf spring. It is also possible to form the spring mechanism on a separate component, such as a fastening element, or on the cover plate. The integral design also has the advantage that the total number of components is reduced, which is reflected in the ease of use and disassembly.

Provision can furthermore be made for the cover plate to be designed to be rotatable or pivotable on the base plate about a pivot axis which preferably runs in the transverse direction. The opening direction of the cover plate can thus be provided by a person skilled in the art normal to the running direction about a vertical axis or also in the horizontal direction.

In the case of a cover plate designed to be rotatable or pivotable, a multifunctional cover plate designed in this way can have at least one hinge-like joint for easy connection of the cover plate to the base plate. In extreme cases, this joint can be designed to be elastic, for example by means of pins on a rotary extension of the cover plate and pockets of complementary shape on the receptacle of the base plate. However, it can be advantageous to form the articulated connection by means of a pin, about which the cover plate can rotate. It should be relatively easy for the average person skilled in the art to design a connection between the base plate and the cover plate on the basis of the present disclosure.

However, it is also possible to displace the cover plate laterally and/or vertically on the base plate. A combination of sliding and pivoting movement is also conceivable for moving the cover plate from the open to the closed position or vice versa. The design of a slide also has the advantage that there is no significant change in the outer contour of the gun, neither in the open position nor in the closed position, and the overall dimensions of the gun are therefore as small as possible.

When designing a slide, it has proven to be advantageous if the base plate has at least one guide groove for interacting with at least one guide extension of the cover plate that is complementary in shape and function. Again, it is up to the person skilled in the art to adapt the sliding or pivoting direction, depending on the intended size and shape of the multifunction cover plate, to his needs with relatively little effort on the basis of the present disclosure.

In some embodiments, it can be advantageous if the base plate and/or the cover plate has extensions that are designed to protrude laterally opposite the carriage, at least on one side. In this way, simplified operation of the cover plate and/or the carriage, e.g. during a manual loading process, can be achieved.

In addition, it has proven to be advantageous to provide contours and/or outer surfaces of the multifunctional cover plate with a surface structure. This can be in the form of knobs, ribbing or the like and can make it easier for the operator to grip, disassemble and possibly even operate the carriage, e.g. during a manual loading process.

Other components of a handgun, in particular a pistol, such as the grip, various safety devices or the firing pin device are not explained in more detail within the scope of this invention, since the person skilled in the art can also make modifications here relatively easily based on his specialist knowledge, depending on the present description.

In the following, the terms left, right, above, below, in front and behind always refer to the direction in which the firearm is fired from the point of view of the shooter when it is held ready to fire. The weapon has a central weapon plane that runs through the barrel axis and is oriented vertically, which, cum grano salis, forms a plane of symmetry.

The 1 shows an example of an exploded view of a pistol with only a few main assemblies, such as a slide 1, a barrel 12, a return spring group or closing spring unit 13 and a grip or frame 14. At the rear of the slide 1 is one known from the prior art , Grooved cover plate receptacle 11 is formed, wherein a cover plate 15 or a multifunction cover plate 2 can be at least partially accommodated. The 1 applies to all exemplary embodiments and is primarily intended to provide a better understanding of the installation situation of the multifunction cover plate 2 .

In 2 a previously known cover plate 15 and some exemplary embodiments for multifunctional cover plates 2 can be seen. where is in Figure 2a to see a cover plate 15, as is very often installed in pistols in a known manner. It consists essentially only of the base plate 21, which is designed in such a way that it can be pushed into the cover plate receptacle 11 and thereby closes the carriage on the back. Compare the dotted movement arrow in 1 . Inside the cover plate 15 there is a circuit board 22 which is made of metal and serves to reinforce the cover plate 15 . Two recesses 23 can be seen on the underside of the cover plate 15, which serve as passages for the ejector and the control spring when the carriage 1 is removed from the grip 14.

In figs 2b, 2c and 2d exemplary embodiments of multifunctional cover plates 2 according to the invention can be seen, each of which has a cover plate 31 which is designed to be movable relative to a modified base plate 21 . The variants shown in the figs 2b and 2c formed with a pivotable cover plate 31, while the embodiment in Fig. 2d is shown as a sliding cover plate 31.

In the following, these exemplary embodiments will be explained in more detail by way of example, which are representative of the concept of a multifunctional cover plate 2 according to the invention. It should be expressly mentioned that combinations that are not shown, in particular a combination of a pivotable and displaceable cover plate 31 are also included in the invention.

The 3 shows an example of a carriage 1 with a mounted multifunction cover plate 2 in a closed position 311 ( Figure 3a ), as well as an open position 312 ( Figure 3b ). It is clearly visible in the open position 312 that the cover plate 31 is designed to be pivotable to the rear to such an extent that the movement path for removing the carriage 1 to the front, i.e. in the direction of travel 91, is released, even if the aforementioned components of the handle 14, which are not shown for the sake of simplicity, are arranged in the handle.

In synopsis with figs 3a and 3b will from the figs 4 and 5 the closed position 311, or open position 312, can be seen particularly well. The 4 corresponds to a cross-sectional view on the plane AA' Figure 3a in the closed position 311, while the figure 5 analogously to the open position on the BB' level Figure 3b reflects. In the selected illustration, the sections shown do not run through the center plane of the weapon, but viewed in the transverse direction 92 in the first third. This is approximately at the height of the hinge joints shown. In these figures, a snap-in connection 32 can be seen very clearly, which in the present exemplary embodiment is formed from a snap-in extension 33 on the base plate 21 and two snap-in notches 34 on the cover plate 31 . Using this latching connection 32, two latching positions can be formed in a relatively simple manner, which correspond to the closed and open positions 311 and 312, respectively.

Furthermore, from the figs 4 and 5 in synopsis with figs 1 and 3 it can be seen that in the open position 312 the carriage guide 16 is fully released in order to allow the carriage 1 to be pulled off. This relationship applies mutatis mutandis to all exemplary embodiments according to the invention and will therefore not be explained separately later.

In 6 is a perspective view of a multifunction cover plate 2 seen obliquely from the front. The base plate 21 can be seen in which a circuit board 22 can be received. Furthermore, recesses 23 on the base plate 21 can be seen. It can also be easily understood from this illustration that the cover plate 31 is the base plate when viewed from below and/or from the side 21 is extended in the closed position 311 and thus seals the carriage 1 relatively well on the back.

The 7 shows the multifunction cover plate 2 6 viewed from behind in an exploded view. In synopsis with the 8 , which has a cross-section in the running direction 91 on the plane CC' 4 represents, the formation of a hinge joint by means of a pin 37 about a pivot axis 38 can be understood very well in the installation situation.

From the figs 2 B , 3a and b , as well as figs 6 to 8 an additional recess at the upper edge of the multifunction cover plate 2 can also be seen. This additional recess can be provided on the base plate 21 in order to facilitate the disassembly and assembly of the extractor unit, for example in order to actuate it with a disassembly pin.

From the figs 6 and 7 a particularly preferred embodiment can also be seen, according to which extensions 39 projecting laterally over the width of the carriage 1 are formed. These extensions 39 can be used in order to be able to actuate the carriage 1 more easily during the manual loading process, which gives the multifunction cover plate 2 an additional benefit.

In the figs 9 to 13 a further exemplary embodiment of a multifunction cover plate 2 is explained in more detail. In the 9 FIG. 9 is a cross section in the transverse direction 92 through the rear region of the carriage 1 in the closed position 311, analogous to FIG 4 , evident. Mutatis mutandis this applies to 10 analogous to figure 5 . This embodiment is also provided with a cover plate 31 that can be pivoted about a pivot axis 38 . In addition, from these two representations in conjunction with the figs 11 to 13 an embodiment of a spring mechanism 35 can be seen, which can in principle be designed to be compatible with all embodiments according to the invention.

The assembly of the multifunction cover plate 2 of this embodiment can very well from the exploded views of figs 11 and 12 be traced. In In this particular example, the spring mechanism 35 is installed by a fastener 40 which can be inserted into the base plate 21 from the rear. The spring mechanism 35 is integrally formed on the fastening element 40 in the form of a type of leaf spring and acts downward when the cover plate 31 is installed.

The advantageous design of a flattened area 36 on the cover plate 31, more precisely on the hinge joint of the selected representation, can be used to use the spring mechanism 35 analogously to the function of a latching connection 32, since the leaf spring rests prestressed on the flattened areas 36. How from the figs 9 and 10 As can be seen very clearly, the cover plate 31 can thus be held in position in the closed position 311 or open position 312 by the spring mechanism 35 . This is also from the cross-sectional view in the direction of 91 of 13 , viewed from the plane CC' 9 , very well clearly.

In 13 a very similar structure to that of the previous exemplary embodiment is also shown, with a pivot axis 38 running perpendicularly to the running direction 91 in the transverse direction 92 . In addition, extensions 39 that are excellently formed laterally over the width of the carriage 2 can be clearly seen in this quasi-rear view. It is easy to imagine the pivot axis 38 also being designed, for example, in the vertical direction 93, ie in such a way that the cover plate 31 can be opened essentially "door-like".

In 14 1 is another embodiment of a multifunction cover plate 2 installed in a carriage 1 in the closed position 311. FIG. This is an example with a cover plate 31 which is designed to be displaceable relative to the base plate. The direction of displacement between the closed position 311 and the open position 312 can be designed at an angle or, for reasons of space, normal to the direction of travel 91, as can be seen from a synopsis with the figs 15 to 19 turns out well.

As in the exemplary embodiments above, lateral extensions 39 are also formed on the base plate 21 here, but these are not absolutely necessary.

In the figs 17 and 18 are lateral cross-sections on the plane AA 'or BB', analogous to the previous embodiments can be seen. Due to the symmetrical design of the present exemplary embodiment, the position of the exact sectional plane is not important, but merely to illustrate the basic possibility of designing the cover plate 31 as a slide.

The cover plate 31 can as in synopsis with the figs 19 and 20 can be seen very clearly, can be simply inserted into the base plate 21 from below and, as shown in the present illustrations, is also supported by it on several sides. In principle, it is also conceivable to design the cover plate to be displaceable laterally, ie, for example, in the transverse direction 92 .

In the case of the sliding variants, it has proven to be advantageous if the cover plate 31 is connected to the base plate 21 via at least one sliding connection or a pair of guides. Such a guide pair can unilaterally or, as in the figs 17 to 19 can be seen very well, also be developed on both sides. The pair of guides can thus have at least one guide groove 41 and a guide extension 42 that is complementary in form and function. The orientation or arrangement of these elements can of course also be reversed on the base plate 21 and cover plate 31 . This can be designed as a simple tongue and groove connection, or as a dovetail connection, for example, in order to make tilting transverse to the direction of displacement more difficult.

It is also within the scope of the invention not to allow the cover plate 31 to disappear completely within the base plate 21, as in the preferred illustrated variant, but that the cover plate 31 can also be arranged outside the base plate 21. The features designed below can also be arranged at least partially outside of the base plate 21, such as a pair of guides or a snap-in connection 32.

As previously noted, the sliding variants can also be implemented with a spring mechanism 35 which preferably urges the cover plate 31 into the closed position 311 . For reasons of clarity, such a representation is not included shown, however, it is readily possible for those skilled in the art to provide a spring mechanism with the aid of the present disclosure. For example, a leaf spring can be formed, preferably integrally, on the slide-shaped cover plate 31 . See, for example, the explanations for the second exemplary embodiment.

One or more latching connections 32 can also be combined very well with a displaceably arranged cover plate 31, as is the case in FIGS figs 19 and 20 emerges. The cross section CC' in 20 is appropriate 17 chosen so that the latching extensions 33 on the base plate 21 and the form and function complementary latching notches 34 are particularly easy to recognize. This snap-in connection 32 can also be designed optionally, for example if a spring mechanism 35 is provided and you want to keep the cover plate 31 in the open position 312 to further simplify the operability. It is also conceivable to provide an additional element, such as a fastening element 40 for arranging a latching connection 32 and/or a spring mechanism 35, or also the sliding connection.

Likewise is from the 19 As can also be seen from the preceding description, a particularly preferred embodiment can be seen, according to which surface structuring can be provided on at least one outer surface or also the outer contour. This not only has the advantage of simple actuation, but also that handling that is averted from sight can be facilitated by touch.

In the description and claims, "substantially" means a deviation of up to 10% of the specified value, if physically possible, both upwards and downwards, otherwise only in the sensible direction. The term: "combination" or "combinations" stands, unless otherwise stated, for all types of combinations, starting from two of the components concerned up to a plurality or all such components, the term: "containing" also stands for "consisting out of".
