Abstract

The invention relates to a method for producing a modular rifle stock and a modular rifle stock. The rifle stock comprises a number of stock parts that are manufactured separately and then connected, including a rear stock (5), a front stock (2) and at least one center stock adapter (3, 4). All shaft parts consist of a material comprising plastic and at least some of the shaft parts to be connected are connected to one another in a materially bonded and non-detachable manner.

Description

The invention relates to a method for producing a modular rifle stock and a modular rifle stock for accommodating further firearm components to form a firearm or a rifle.

As is known per se, a stock of a rifle or a long gun is functionally primarily provided for connecting the other main assemblies of the corresponding weapon system and as a handling or gripping option and support. Depending on the weapon system or weapon type, rifle stocks are usually either made in one piece, such as in the case of a bolt-action rifle, or the long weapon has a forearm and a structurally separate buttstock, such as in the case of a break-open weapon. For different weapon types or different weapon systems, for example depending on the design as a bolt-action rifle, single-shot rifle, shotgun, etc., but also to take into account individual requests, a stock or fore-end and rear stock must be adapted to the remaining assemblies of a respective weapon system.

A disadvantage in this context is the poor production efficiency caused by the respectively required adaptation of a stock or the stock parts to a weapon system, which in particular leads to high production costs.

the end DE 10 2015 106 291 A1 a firearm is known which comprises a multi-part stock system, in particular a front stock, a central stock and a stock. The three-part shape of the stock enables a change between different housings, in particular housing sizes and calibres, while reusing the fore-end and rear stock, with only the middle part having to be adapted to different housings. The three shaft parts of the DE 10 2015 106 291 A1 are connected to each other via plug-in screw connections, so that their connection can be released to change the housing and another central stock can be connected to the stock and forestock. However, such a design of a rifle stock has proven to be disadvantageous in terms of long-term stability and resistance to deformation, in particular warping and damage. This is especially the case when a rifle is used heavily comprising such a shaft system with detachable plug-in screw connections, also due to the high mechanical stress when firing the rifle.

The object of the present invention was to overcome the disadvantages of the prior art that still exist and to provide a method by means of which a method- and cost-efficient production of a rifle stock, in particular with a low weight, is made possible, and yet a high long-term (shape) stability and resistance to deformation and damage to the rifle stock. In addition, the object of the invention was to provide a rifle stock that is particularly light in weight, which can be produced in a process-efficient and cost-efficient manner and nevertheless has high long-term stability and resistance to deformation and damage.

On the one hand, this object is achieved by a method according to the claims.

The process for manufacturing a modular or composite rifle stock includes:
Production of several stock parts comprising a butt stock, a fore stock and at least one middle stock adapter, positioning the stock parts relative to each other in a joining position or connecting position, and connecting the stock parts in the joining position.

In the method, all shaft parts are made from a material that includes plastic. One or more center shaft adapters can be manufactured here. At least some shaft parts to be connected are connected to one another in a material-locking or material-locking manner and not detachably or not detachably detachably.

In particular, all shaft parts that are to be rigidly connected to one another can be connected to one another in a materially bonded and non-detachable manner.

Provision can be made for only one center stock adapter to be produced and connected both to the rear stock and to the fore stock. Depending on the type of weapon, for example, it can also be provided that several center shaft adapters are manufactured. In the case of the production of two center stock adapters, for example, one center stock adapter can be connected to the rear stock and the second center stock adapter, and the second center stock adapter can also be connected to the forearm. Basically it is with two middle stock adapters, however, it is also possible for one of the two middle stock adapters to be connected to both the buttstock and the forearm and the second middle stock adapter. Of course, more than two center stock adapters can also be produced and connected to one another or at least one of the center stock adapters can be connected to the butt stock and another of the center stock adapters can be connected to at least the fore stock. Depending on the type of weapon system, e.g. design as a bolt-action rifle, single-shot rifle, shotgun and so on, the person skilled in the art can produce a suitable number of center stock adapters in a suitable design and connect them to one another and to the other stock parts.

A connection, in particular a materially bonded connection, of the individual shaft parts can in principle take place simultaneously or also in a sequential order. It can therefore be provided that all shaft parts are brought into the joining position and connected at the same time, or that individual shaft parts are first connected to one another in a joining position and such a shaft part assembly is then connected to one or more other shaft parts.

A modular rifle stock can be produced in a process-economical and cost-efficient manner by the specified measures. In particular, the butt stock and the fore stock can be manufactured in large numbers in a cost-effective manner, and an adaptation to a respective (desired) weapon system can be carried out simply by individually manufacturing the central stock adapter or adapters. As is known per se, depending on the weapon system for which a respective rifle stock is intended, different bedding surfaces and, if necessary, pockets for bedding or connection of the respective weapon system can be designed on the central stock adapter(s). The central stock adapter or adapters can be designed to connect the universal stock parts, which can therefore be manufactured in the same way for different weapon systems, namely stock and forestock. The stock and the fore-end can be made, for example, by injection moulding.

Nevertheless, the rifle stock or a long gun equipped with such a rifle stock can be given improved long-term stability or long-term dimensional stability and high resistance to deformation, distortion and damage. In particular, the assembled rifle stock due to the cohesive, non-detachable Connection of the shaft parts can be given a high level of shock resistance, which is particularly beneficial when firing shots frequently, i.e. when the long gun equipped with the rifle stock is used frequently, and thus high reliability is provided over a long period of time. A rifle stock with a relatively low weight can also be provided by the specified measures.

Regarding the connection of the shaft parts, it can preferably be provided in the method that shape-complementary connecting segments are formed at the end regions of two shaft parts to be cohesively connected, via which shape-complementary connecting segments the relevant shaft parts are glued together.

One of the respective shape-complementary connection segments can be configured on one of the shaft parts, and the other connection segment, which has a complementary shape thereto, can be configured on another shaft part to be connected to this shaft part.

Connecting the shaft parts by gluing correspondingly shaped, shape-complementary connecting segments represents a process- and cost-efficient connection method, through which a (dimensionally) stable and reliably durable connection of the shaft parts can nevertheless be provided.

In this context, it can preferably be provided that corresponding joining surfaces are formed on the respective shape-complementary connecting segments of two shaft parts to be connected in a materially joined manner, which joining surfaces are arranged facing one another in the joining position in such a way that a receiving space is formed between the joining surfaces, which receiving space is formed in the course of the connection filled with a curable adhesive and the adhesive is cured.

Due to the targeted shaping of the receiving space in the joining position, a sufficient amount of adhesive can be used for securely connecting shaft parts of shaft parts.

In this case, it can also preferably be provided that in each case shape-complementary connecting segments of two shaft parts to be connected in a materially bonded manner are formed in such a way that a first connecting segment is opposite to the immediately adjacent one The shank section of the corresponding shank part has a tapered section or region with an outward-facing joint surface, and the second connection segment, which is complementary in shape to this, has an inward-pointed joint surface, with the tapered section of the first connection segment protruding into the second connection segment and the second connection segment in the joining position encases the tapered section of the first connecting segment, the receiving space being formed between the outward-pointing joining surface of the first connecting segment and the inward-pointing joining surface of the second connecting segment, which receiving space is filled with the hardenable adhesive during the course of the connection and the adhesive is hardened.

A particularly durable, dimensionally stable and deformation-resistant connection of shaft parts can be provided by this design of shape-complementary connecting segments. The receiving space for the adhesive can also be referred to as a cavity, intermediate space or joining space. In principle, any adhesive suitable for joining the shaft part materials can be used as the adhesive. A 2-component adhesive comprising a crosslinkable or curable, functionalized resin and a hardener for the resin is preferably used as the adhesive. In particular, a resin functionalized with epoxy groups can be used as the curable resin.

The precise geometric design of two connecting segments with complementary shapes or their joining surfaces can in principle be carried out in a variety of ways, with a basic geometric shape or cross-sectional shape of connecting segments with complementary shapes being of course essentially dictated by the basic shape of the shaft parts in question in the area or adjacent to a connecting segment. The fore-end and a central stock adapter to be connected to it can be designed in the area of the connecting segments, for example for embedding or supporting a gun barrel and for gripping or holding the gun by a shooter, and the respective, shape-complementary connecting segments can at least largely have a corresponding cross-sectional or have basic form. The connecting segments per se can be designed, for example, in the form of simple longitudinal connections with joining surfaces that are opposite one another and spaced apart from one another. In principle, however, other or additional versions of geometrically shaped connections are also conceivable in the case of two connection segments with complementary shapes, for example in the form of a so-called blade joint connection. Additionally Elements of two connecting segments with complementary shapes can also be designed for form-fitting interlocking, such as in the manner of a dovetail connection.

Two connection segments with complementary shapes can be connected, for example, by applying a hardenable adhesive to a joining surface of a connection segment and bringing it into the joining position and joining with the connection segment that has a complementary shape in each case. Of course, the hardenable adhesive can also be applied to both joining surfaces of two connecting segments with complementary shapes and then the corresponding shaft parts can be joined in the joining position while the adhesive hardens.

In the method with regard to the gluing of the upper parts in at least one of two connecting segments with complementary shapes, an adhesive channel or several adhesive channels can preferably be formed in the course of the production of the upper parts, such that the adhesive channel or the adhesive channels opens into the receiving space in the joining position, wherein in the joining position, the adhesive is filled into the receiving space via the adhesive channel or via the adhesive channels.

This procedure represents an embodiment of the method that is particularly reliable in terms of execution, since the adhesive can be filled into the receiving space via the adhesive channel or channels in the case of shaft parts that are already pre-positioned. In this way, the receiving space and the adhesive channel or channels can be filled as completely as possible, so that the connected stock parts of the fully assembled rifle stock do not have any defects and therefore no weak points in the area of the connecting segments. In addition, this embodiment represents a process-efficient variant, since the adhesive can be injected or injected into the adhesive channel or channels from the outside in a manner that is easy to carry out and also as error-free as possible.

In this context, it can also be provided that reinforcing rods are inserted into the adhesive channels after they have been filled with the adhesive and before the adhesive has hardened.

After the adhesive has hardened, such reinforcement rods can in particular result in improved dimensional stability and (long-term) resilience in the area of the adhesive connections or in the Area of the connected connecting segments can be achieved. The reinforcing rods can essentially be made from the same material or material comprising plastic as the shaft parts. The reinforcing rods can be of essentially cylindrical design, with fundamentally different cross-sectional shapes being possible, for example oval or circular, cuboid, square or triangular cross-sectional shapes. A longitudinal extent of a reinforcement bar can at least essentially correspond to a longitudinal extent of the corresponding adhesive channel into which the relevant reinforcement bar is inserted.

In principle, it can be sufficient to form a connection segment on each of the shaft parts that is provided for connection to another, shape-complementary connecting segment, so that a connection is produced between the individual shaft parts.

In some cases or with certain weapon systems, however, it can also be expedient if two or more connecting segments are formed on the rear stock for connection to one or more other stock parts.

Such a variant can be advantageous above all in the case of certain stock part geometries, such as when the rear stock is designed as a so-called thumbhole stock. In addition, the following connection to one or more shaft parts via the two or more connection segments can contribute to increasing the dimensional stability.

As already mentioned, depending on the type of weapon, it may be sufficient to produce a center stock adapter and connect it to the rear stock and the fore stock.

Depending on the type of weapon or the shape of the buttstock and/or forend, it can also make sense to produce two or more middle stock adapters, with one middle stock adapter being connected to the buttstock, another middle stock adapter to the forearm and each middle stock adapter to a different middle stock adapter.

Essentially, this method allows the method to be used to produce rifle stocks for all common weapon systems.

Furthermore, in the method, the center shaft adapter or adapters can be produced by means of an additive manufacturing process, in particular by means of 3D printing.

However, the center shaft adapter or adapters can also be produced by means of resin injection processes.

The specified production methods enable an individual production of central stock adapters in a particularly efficient manner, and thus an easily adaptable production of rifle stocks for a wide variety of weapon types.

Finally, in a further development of the method it can be provided that the shaft parts are predominantly formed by fiber-reinforced plastic material with a weight proportion of fibers of 20% by weight to 80% by weight.

This measure makes it possible to provide light but nevertheless hard and robust stock parts for producing the rifle stock. In principle, all common, natural or synthetic reinforcing fibers can be used as fibers, such as polyester fibers, polyamide fibers, glass fibers, but also, for example, hemp fibers. Carbon fibers can preferably be used to produce the shaft parts and optionally also reinforcement rods. Furthermore, the shaft parts can preferably be formed by fiber-reinforced plastic material with a weight proportion of fibers of 40% by weight to 70% by weight.

The object of the invention is also achieved by a rifle stock of modular construction or assembly, which rifle stock is provided for the connection of further firearm components to form a firearm or long gun or rifle. The rifle stock can be produced in particular by means of the above method, exclusively or including the method variants mentioned.

The rifle stock comprises a number of stock parts that are manufactured separately and then connected, including a rear stock, a forestock and at least one center stock adapter.

All stock parts of the rifle stock consist of a material comprising plastic and at least some stock parts to be connected are connected to one another in a materially bonded and non-detachable or non-destructively detachable manner.

In particular, all shaft parts that are to be rigidly connected to one another can be connected to one another in a materially bonded and non-detachable manner.

An advantage of this modular design is the possible, simple adjustment and use of the rifle stock for different weapon types or weapon systems, for example different versions of a rifle, such as a bolt-action rifle, single-shot rifle or shotgun and so on. This is because, in order to adapt to a specific weapon system, only the central stock adapter or adapters has to be varied. This also enables the rifle stock to be manufactured in a process- and cost-efficient manner.

At the same time, the rifle stock designed in this way has good long-term stability or long-term dimensional stability and high resistance to deformation, distortion and damage. In particular, the modular or assembled rifle stock is characterized by a high level of shock resistance due to the integral, non-detachable connection of the stock parts, which is particularly beneficial when firing shots frequently, i.e. when the long gun equipped with the rifle stock is used frequently, and thus a high reliability over a long period of time. In addition, the rifle stock has a relatively low weight.

The rifle stock can only include a structurally separately manufactured central stock adapter which is connected to both the buttstock and the forestock. However, a rifle stock can also have two center stock adapters, for example, with one center stock adapter being able to be connected to the rear stock and the second center stock adapter, and the second center stock adapter also being able to be connected to the front stock. In the case of two central stock adapters, however, it can also be expedient, for example depending on the geometric design, if one of the two central stock adapters is connected to both the rear stock and the forestock and the second central stock adapter. Of course, more than two center stock adapters can also be produced and connected to one another or at least one of the center stock adapters can be connected to the butt stock and another of the center stock adapters can be connected to at least the fore stock. In principle, the rifle stock can also have more than two center stock adapters, which can each be connected to other stock parts in a wide variety of ways. The number of center stock adapters and their connection to each other and to the other stock parts can be made primarily on the basis of the requirements of the firearm or rifle to be equipped with the rifle stock or the corresponding physical configuration of the stock parts.

Preferably, materially connected shaft parts can be glued via connecting segments formed on the end regions of the shaft parts, wherein the connecting segments of two shaft parts connected to one another can each be formed with complementary shapes.

One of the respective shape-complementary connection segments can be configured on one of the shaft parts, and the other connection segment, which has a complementary shape thereto, can be configured on another shaft part to be connected to this shaft part.

This design allows a rifle stock to be provided with a (dimensionally) stable and reliably durable connection of the individual stock parts.

In a development of the rifle stock, corresponding joining surfaces can be formed on the respective shape-complementary connecting segments of two materially connected stock parts, between which joining surfaces a receiving space is formed, which receiving space is filled with a hardened adhesive.

Due to these features, a permanent, dimensionally stable connection of the shaft parts can be achieved.

Furthermore, in the case of the rifle stock, it can be provided in this context that the connecting segments of two stock parts that are materially joined to one another, which are complementary in shape, are designed in such a way that a first connecting segment has a section or area that is tapered compared to the immediately adjacent stock section of the corresponding stock part, with a joint surface pointing outwards and the second connecting segment, which is complementary in shape thereto, has an inwardly pointing joining surface, the receiving space being formed between these two joining surfaces, which receiving space is filled with the hardened adhesive.

With this embodiment, the long-term dimensional stability and resistance to deformation of the rifle stock can be improved even further. The receiving space filled with the adhesive can also be referred to as a cavity or joining space. In principle, the adhesive can be formed by any adhesive suitable for joining the shaft part materials. The adhesive can preferably be formed by a 2-component adhesive. In particular, the adhesive can be formed by a functionalized resin cured by means of a hardener or crosslinking agent, preferably by an epoxy duroplastic.

The connecting segments can be designed, for example, in the form of simple longitudinal connections with joining surfaces that are opposite one another and are spaced apart from one another. In principle, however, other or additional configurations of geometric shape connections are also possible in the case of two connection segments with complementary shapes, for example in the form of a so-called blade butt connection. In addition, elements of two connection segments with complementary shapes can also be designed for form-fitting engagement with one another, such as in the manner of a dovetail connection.

In a further embodiment of the rifle stock, it can be provided that an adhesive channel or several adhesive channels is or are formed in at least one of two connecting segments with complementary shapes, which adhesive channel or adhesive channels opens into the receiving space, and which adhesive channel or adhesive channels at least partially with cured adhesive is or are filled.

Subsequently, a reinforcement rod can be arranged in each of these adhesive channels.

Due to these features, improved dimensional stability and (permanent) resilience can be provided in the area of the adhesive connections or in the area of the connected connection segments. The reinforcing rods can essentially be made from the same material or material comprising plastic as the shaft parts. The reinforcing rods can be essentially cylindrical, with fundamentally different cross-sectional shapes being possible, for example oval or circular, cuboid, square or triangular cross-sectional shapes. A longitudinal extent of a reinforcement bar can at least essentially correspond to a longitudinal extent of the corresponding adhesive channel into which the relevant reinforcement bar is inserted.

In principle, the shaft parts can each be connected via only one connection or adhesive bond formed by two connection segments of complementary shape.

However, it can also be advantageous if two or more connecting segments are formed on the rear stock, via which connecting segments the rear stock is connected to one or more other stock parts.

Such an embodiment variant of the rifle stock can be advantageous above all with certain stock part geometries, such as when the rear stock is designed as a so-called thumbhole stock. In addition, the following connection to one or more shaft parts via the two or more connection segments can contribute to increasing the dimensional stability.

Furthermore, the rifle stock can be provided with two or more center stock adapters, one center stock adapter being connected to the buttstock, another center stock adapter to the forearm and the center stock adapters each being connected to a different center stock adapter.

Due to these features, use of the modular rifle stock can essentially be provided for all common weapon systems.

Finally, the stock parts of the gun stock can consist predominantly of fiber-reinforced plastic material with a weight proportion of fibers of 20% by weight to 80% by weight.

As a result, a light but nevertheless hard and robust rifle stock can be made available. In principle, the reinforcing fibers can be formed by all common, natural or synthetic reinforcing fibers, such as polyester or polyamide fibers, glass fibers, but also, for example, hemp fibers. The fiber reinforcement can preferably be formed by carbon fibers. Furthermore, the shaft parts can preferably be formed by fiber-reinforced plastic material with a weight proportion of fibers of 40% by weight to 70% by weight.

For a better understanding of the invention, it is explained in more detail with reference to the following figures.

As an introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numbers or the same component designations, it being possible for the disclosures contained throughout the description to be applied to the same parts with the same reference numbers or the same component designations. The position information selected in the description, such as top, bottom, side, etc., is related to the directly described and illustrated figure and these position information are to be transferred to the new position in the event of a change in position.

In the 1 1 shows an exemplary embodiment of a rifle stock 1 that is constructed modularly or is composed of a plurality of stock parts 2, 3, 4, 5 that are connected to one another. As is known per se, the rifle stock 1 is provided for the connection or embedding of further firearm components, such as the housing, rifle barrel and further, possibly optional, components of a rifle. For reasons of clarity, such other firearm components are shown apart from the rifle stock 1 or the stock parts 2, 3, 4, 5 in 1 and the other following figures are not shown, since such firearm components are well known to those of ordinary skill in the technical field of firearms.

the inside 1 The rifle stock 1 shown as an example includes a forearm 2, at least one center stock adapter 3, 4 and a stock 5, with a first center stock adapter 3 and a second center stock adapter 4 being included in the illustrated embodiment. Depending on the type and design of the weapon system provided for the rifle stock 1, i.e., for example, depending on the design as a bolt-action rifle, shotgun, break-open rifle, etc., or depending on the other weapon components to be attached or accommodated to the rifle stock 1, a rifle stock 1 but also only include a central shaft adapter 3 . Depending on the type of weapon, a rifle stock 1 can include two or more center stock adapters 3, 4.

All shaft parts 2, 3, 4, 5 consist of a material comprising plastic, or are accordingly made of a material comprising plastic.

At least some shaft parts 2, 3, 4, 5 of the rifle stock 1 to be connected according to FIG 1 are each connected to one another in a material-to-material and non-detachable manner. In particular, shaft parts 2, 3, 4, 5 that are rigidly connected to one another can be connected to one another with a material fit. At the in 1 In the exemplary embodiment shown, two center stock adapters 3, 4 are connected to the rear stock 5, the center stock adapter 3 is connected to the front stock 2, and the center stock adapters 3, 4 are each connected to one another with a material fit.

In the method for producing a modular rifle stock, one or more central stock adapters 3, 4 can be produced accordingly, with at least some stock parts 2, 3, 4, 5 to be connected being connected to one another in a materially bonded and non-detachable manner. At the in 1 and 2 In the illustrated embodiment, the center stock adapter 3, 4 can be connected to the rear stock 5, a center stock adapter 3 with the forearm 2 and the center stock adapters 3, 4 are each connected to one another 3, 4 in a materially bonded manner.

The stock parts 2, 3, 4, 5 can preferably be formed predominantly from fiber-reinforced plastic material with a weight proportion of fibers of 20% by weight to 80% by weight, so that the stock parts 2, 3, 4, 5 of the rifle stock 1 are predominantly made of fiber-reinforced plastic material with a weight proportion of fibers of 20% to 80% by weight. As a result, hard, rigid and robust shaft parts 2, 3, 4, 5 can be realized with a low weight. In principle, all common, natural or synthetic reinforcing fibers can be used as fibers, such as polyester fibers, polyamide fibers, glass fibers, but also, for example, hemp fibers. Carbon fibers can preferably be used to produce the shaft parts and optionally also reinforcement rods. The shaft parts can preferably be made of fiber-reinforced plastic material with a weight proportion of fibers of 40% by weight to 70% by weight.

The center stock adapter(s) 3, 4 can be adapted to a respective weapon system or to customer requirements, while the stock 5 and the forestock 2 can always be manufactured in large quantities as universally usable stock parts 2, 5, for example by injection molding.

In particular, bedding surfaces and possibly also bedding pockets for bedding a housing or any other weapon components can be formed in the central stock adapter(s) 3 ,4. Viewed the other way around, the center stock adapter(s) 3, 4 can also be regarded as a means for connecting the forearm 2 and the rear stock 5, ie the universal stock parts 2, 5, to a respective weapon system, in particular to its housing.

The central shaft adapter or adapters 3, 4 can preferably be produced by means of an additive manufacturing process, in particular by means of 3D printing.

Alternatively, the center shaft adapter or adapters 3, 4 can also be produced by means of a resin injection process.

At the in the 1 For example, the fore-end 2 is connected to the first central stock adapter 3 , this first central stock adapter 3 is connected both to the second central stock adapter 4 and to the rear stock 5 , and the second central stock adapter 4 is also connected to the rear stock 5 . Of course, in addition to a variation in the number of center stock adapters 3, 4 depending on the embodiment of the weapon system provided for the rifle stock 1, there is also a variation in the design of the center stock adapter(s) 3, 4, as well as a variation in the number and arrangement or placement of the connections between individual shaft parts 2, 3, 4, 5 basically possible. A corresponding configuration of the individual stock parts 2, 3, 4, 5 can be carried out by a person skilled in the art primarily based on the shape and dimensions of the weapon components to be connected, and also based on specified customer requirements. The number and placement of connections can essentially be made based on the geometric shape of the individual shaft parts 2, 3, 4, 5.

For example, a fore-end 2 can have a trough-like design or can be designed in the process. The rear stock 5 can preferably be constructed or designed as a hollow body. As already mentioned, the configuration of the center shaft adapter(s) 3, 4 can be carried out primarily depending on a weapon system to be equipped with it, or can be adapted to a respective weapon system. All shaft parts 2, 3, 4, 5 can have an average wall thickness of approximately 1 mm to 3 mm, such as approximately 1.5 mm.

How best by synopsis of 1 and the inside Fig.2 As can be seen in the exploded view shown, the stock parts 2, 3, 4, 5, i.e. stock 5, forestock 2 and at least one central stock adapter 3, 4 are structurally manufactured separately and then connected to one another. At the in the 1 In the exemplary embodiment shown for a rifle stock 1, all stock parts 2, 3, 4, 5 are made of a plastic material and the stock parts 2, 3, 4, 5 are connected to one another in a materially bonded and non-detachable manner.

The method for producing the rifle stock 1 accordingly comprises the production of a plurality of stock parts 2, 3, 4, 5, at least one stock 5, a front stock 2 and at least one center stock adapter 3, 4 2 or also in Fig.1 illustrated embodiment, two center shaft adapter 3, 4 are produced. subsequently become the shaft parts 2, 3, 4, 5 are each positioned relative to one another in a joining position and connected in the respective joining position. A joining position can also be referred to as a connecting or gluing position.

At the in the 2 and 1 illustrated embodiment, all shaft parts 2, 3, 4, 5 can be cohesively connected to each other. Depending on the weapon type, however, only a few shaft parts 2, 3, 4, 5 of a rifle stock 1 can also be materially connected, as will be described below with reference to a further exemplary embodiment. In particular, all shaft parts 2 , 3 , 4 , 5 that are to be rigidly connected to one another can be connected to one another with a material fit.

A corresponding joining position for connecting a fore-end 2 to a central stock adapter 3 according to the exemplary embodiment 1 and 2 is in the 3 shown. Like in the 3 Illustrated by way of example using the fore-end 2 and the central stock adapter 3, a positioning device 6 or holding device 6 can be used for positioning and holding the respective stock parts 2, 3 to be connected relative to one another. In principle, positioning can be at least partly automated or fully automatic, but of course also manual. A positioning and mounting in the joining position as shown in the 3 The exemplary embodiment shown for connecting the fore-end 2 and central stock adapter 3 can also be used in a similar or analogous manner for connecting to the other stock parts 4, 5 or for connecting the other stock parts 4, 5 to one another. In particular, a correspondingly shaped positioning device or holding device can also be used here.

In principle, the individual shaft parts 2, 3, 4, 5 can be connected simultaneously or also in sequential order. It can therefore be provided that all shaft parts 2, 3, 4, 5 are brought into the joining position and connected at the same time, or that individual shaft parts 2, 3 are first connected to one another and such a shaft part assembly is then connected to one or more other shaft parts 4, 5 is connected.

For the cohesive connection of shaft parts 2, 3, 4, 5, connecting segments 7, 8; 9, 10; 11, 12; 13, 14 are trained, via which shape-complementary connecting segments 7, 8; 9, 10; 11, 12; 13, 14 the relevant shaft parts 2, 3, 4, 5 can be glued together.

As best seen in the exploded view in 2 As can be seen, corresponding connection segments 7, 8; 9, 10; 11, 12; 13, 14 can be formed, with the connecting segments 7, 8; 9, 10; 11, 12; 13, 14 of two shaft parts 2, 3, 4, 5 to be connected in a material-locking manner are or can be designed to be complementary in shape. Accordingly, when in the figure 2 In the exemplary embodiment shown, for example, a connecting segment 7 of the fore-end 2 and a connecting segment 8 of the central stock adapter 3 that is complementary in shape can be provided for connecting. In the illustrated embodiment, the connecting segments 9 and 10, the connecting segments 11 and 12, and the connecting segments 13 and 14 can also be designed with complementary shapes and provided for connecting, as can be seen well from FIG 2 is evident.

As also best based on the 2 can be seen, it can also be provided that two or more connecting segments 9, 11 are formed on the stock 5. In the case of the butt stock 5 designed as a thumbhole stock, this can be expedient, above all due to the shape. How out Fig.1 As can be seen, the rear stock 5 can then be connected via these connecting segments 9, 11 to one or more other stock parts 3, 4, in the exemplary embodiment to the central stock adapter 3 and the further central stock adapter 4. Accordingly, the method can provide for two or more connecting segments 9 , 11 to be formed on the rear stock 5 in the course of manufacturing the stock parts 2 , 3 , 4 , 5 for connection to one or more other stock parts 3 , 4 .

In the exemplary embodiment shown, the connecting segment 9 can be designed to be complementary in shape to the connecting segment 10 of the central shaft adapter 3 and the connecting segment 11 can be designed to be complementary in shape to the connecting segment 12 of the central shaft adapter 4 . A further connection segment 13 of the central shaft adapter 4 can be provided for connection to the central shaft adapter 3 , wherein the central shaft adapter 3 can correspondingly have a connection segment 14 that is complementary in shape to this connection segment 13 . In principle, the center stock adapter 4 can also be viewed as a connecting bridge or connecting piece between the rear stock 5 and the center stock adapter 3, and can be viewed as 2 best seen at least in essence or consist entirely of connecting segments 12, 13. Such a center shaft adapter 4 designed as a connecting piece can be expedient, for example, as an assembly aid.

Further preferred configurations of material connections between stock parts, particularly preferred configurations of each shape-complementary connecting segment, are now explained in more detail with reference to the connection of the fore-end 2 and the central stock adapter 3 or the shape-complementing connecting segments 7 and 8 provided for connecting these stock parts 2, 3. At this point it is noted that other connecting segments that are complementary in shape to one another, i.e. in the exemplary embodiment connecting segments 9 and 10, 11 and 12, and 13 and 14, can also be configured analogously or at least similarly, or can have analogous features, such as in the following based on the shape-complementary connecting segments 7 and 8 and based on the illustrations in FIGS Figures 4 to 6 is described. A basic geometric shape or cross-sectional shape of the respective connecting segments 7, 8, 9, 10, 11, 12, 13, 14 can of course correspond to the basic geometric configuration or cross-sectional shape in this end area of the corresponding shaft part 2, 3, 4, 5, at least in Essentially match how this is mainly based 2 is clearly recognizable.

In the 4 the forearm 2 and the center stock adapter 3 are off 2 and 1 in the area of the connecting segments in detail and enlarged again in an exploded view, i.e. shown in the unconnected state.

How out Fig.4 As can be seen, during the production of the stock parts 2, 3, 4, 5, corresponding joining surfaces 15, 16 can be formed on the respective shape-complementary connecting segments 7, 8 of two stock parts to be connected in a materially bonded manner, here the fore-end 2 and rear stock 3, which are intended for gluing together. These joining surfaces 15, 16 can be arranged facing one another in the joining position such that a receiving space 17 is formed between the joining surfaces 15, 16. A corresponding receiving space 17 formed between the joining surfaces 15 and 16 in the joining position can be seen primarily from the perspective sectional view in FIG figure 5 can be seen, and can be achieved by forming the joining surfaces 15, 16 in such a way that the joining surfaces 15, 16 are at least slightly spaced apart from one another in the joining position. A between mating surfaces 15, 16 in the joining position formed receiving space 17 can also be referred to as a joining space or intermediate space or cavity.

Those of the sectional view in figure 5 and also Fig.6 underlying interface is through the in the 1 illustrated cutting plane 18 marked. In figure 5 the shaft parts 2, 3 are shown in the joining position before the connection, whereas in 6 a perspective sectional view of the forearm 2 and central stock adapter 3 that are already connected to one another in a materially bonded manner is shown.

In the process, in the course of connecting the shaft parts, as shown in the Figures 4 to 6 illustrated connection of the forearm 2 and the center stock adapter 3, the receiving space 17 is filled with a hardenable adhesive 19 and the adhesive 19 is hardened.

Like in the 6 is shown, a rifle stock 1 can therefore have corresponding joining surfaces 15, 16 on the respective shape-complementary connecting segments 7, 8 of two stock parts which are materially connected to one another, in this case fore-end 2 and central stock adapter 3, between which joining surfaces 15, 16 a receiving space 17 is formed, which receiving space 17 is filled with a hardened adhesive 19 .

In principle, any adhesive suitable for joining the shaft part materials can be used as the adhesive. The adhesive can preferably be formed by a 2-component adhesive. In particular, the adhesive can be formed by a functionalized resin that can be cured by means of a hardener or crosslinking agent. In particular, a resin functionalized with epoxy groups can be used, so that the cured adhesive can be formed by an epoxy thermoset.

How best based on the 4 As can be seen, in particular, each form-complementary connecting segment 7, 8 of two stock parts 2, 3 to be connected in a materially joined manner, here for example a fore-end 2 and central stock adapter 3, can be designed in such a way that a first connecting segment 8 is a section that is tapered compared to the immediately adjacent stock section of the corresponding stock part 3 20 with an outwardly pointing joining surface 16, and the second connecting segment 7, which is complementary in shape thereto, has an inwardly pointing joining surface 15. In the joining position as in the 3 shown, can in the process here, the tapered portion 20 of the first connecting segment 8 protrude into the second connecting segment 7 and the second connecting segment 7 encase the tapered portion 20 of the first connecting segment 8, as is also from the figure 5 is evident. As a result, how figure 5 As can be seen, the receiving space 17 can be formed between the outward-pointing joining surface 16 of the first connecting segment 8 and the inward-pointing joining surface 15 of the second connecting segment 7, which receiving space 17 can be filled with the hardenable adhesive 19 in the course of the connection and the adhesive 19 can be hardened.

Like in the 6 illustrated and best viewed by synopsis of 4 and Fig.6 As can be seen, the rifle stock 1 with assembled stock parts 2, 3 can each have connecting segments 7, 8 of complementary shape of two stock parts 2, 3 which are materially connected to one another, here again fore-end 2 and central stock adapter 3 as an example, which connecting segments 7, 8 are designed in such a way that a first connecting segment 8 has a section 20 that is tapered in relation to the immediately adjacent shaft section of the corresponding shaft part 3 and has an outward-facing joining surface 16, and the second connecting segment 7, which is complementary in shape to this, has an inward-facing joining surface 15. As in 6 shown, the receiving space 17 can be formed between these two joining surfaces 15, 16 and filled with the hardened adhesive.

As already mentioned, other of the connection segments with complementary shape, for example connection segments 9 and 10, 11 and 12, as well as 13 and 14 in the described exemplary embodiment, can also be designed similarly or analogously to the connection segments 9 and 10 with complementary shape by looking at them together from 2 and Fig.1 is easily recognizable. In particular, in 2 Again, a tapered section 21 of the connecting segment 9 of the stock 5 with an outwardly facing joint surface 22 can be seen. In the joining position, this joining surface 22 can then be encased by an inwardly facing joining surface of the connecting segment 10 of the central shaft adapter 3 . A cross-sectional shape of the connecting segments 9, 10 of complementary shape can of course deviate from that cross-sectional shape of the connecting segments 7, 8. Basically, two complementary connecting segments 7, 8; 9, 10; 11, 12; 13, 14 form very different types of connection or connecting elements. Shape-complementary connecting segments 7, 8; 9, 10; 11, 12; 13, 14 can be designed, for example, in the form of simple longitudinal connections with mutually opposite and spaced-apart joining surfaces. In principle, however, other or additional versions of geometrical form connections are also possible in the case of two connection segments 7, 8; 9, 10; 11, 12; 13, 14 conceivable, for example in the form of a so-called sheet butt joint. In addition, elements of two complementary connecting segments 7, 8; 9, 10; 11, 12; 13, 14 can also be configured for interlocking engagement, such as in the manner of a dovetail joint.

A cohesive connection of two form-complementary connection segments 7, 8; 9, 10; 11, 12; 13, 14 can be done, for example, by applying a hardenable adhesive 19 to a joining surface 16, 22 of a connecting segment 8, 9 and bringing it into the joining position and joining with the connecting segment 7, 10 of complementary shape. Of course, the hardenable adhesive can also be applied to both joining surfaces of two connecting segments with complementary shapes and then the corresponding shaft parts can be joined in the joining position while the adhesive hardens.

In a preferred embodiment of the method, in at least one of two connecting segments 7, 8; 9, 10; 11, 12; 13, 14 an adhesive channel 23 or several adhesive channels 23 are formed. Corresponding adhesive channels 23 are, for example, in the 1 , 2 , 4 and 5 evident. As best in the Fig.5 is illustrated, an adhesive channel 23 or the adhesive channels 23 can open into the receiving space 17 in the joining position, so that the adhesive 19 can be filled into the receiving space 17 via the adhesive channel 23 or via the adhesive channels 23 in the joining position. In the method, the adhesive 19 can be introduced or injected into the adhesive channels from the outside, for example by means of feeds equipped with injection nozzles, such as hoses or pipes.

Furthermore, in the method, reinforcing rods 24 can be inserted into the adhesive channels 23 after they have been filled with the adhesive 19 and before the adhesive 19 has hardened.

How best from the 6 can be seen, can accordingly in the assembled rifle stock 1 with connected shaft parts 2, 3, 4, 5 in at least one of two shape-complementary connecting segments 7, 8; 9, 10; 11, 12; 13, 14 an adhesive channel 23 or several adhesive channels 23 can be formed, which adhesive channel(s) 23 or which adhesive channels 23 open into the receiving space 17 or open out. At the in the 6 The exemplary embodiment illustrated can be seen in this sectional view, in particular, in this sectional view, two adhesive channels 23 opening into the receiving space 17 or joining space 17, with, for example, in 4 further such adhesive channels 23 can be seen. In the exemplary embodiment illustrated in the figures, in particular all the adhesive channels 23 can be configured in the central shaft adapter 3 .

Like in the 6 shown, the adhesive channels 23 can be filled at least partially, preferably completely, with hardened adhesive 19 .

As further from the 6 As can be seen, a reinforcing rod 24 can be arranged in each of the adhesive channels 23 .

As already described above, such reinforcing rods 24 can be inserted into the adhesive channels 23 after the adhesive channels 23 or receiving spaces 17 have been filled with the adhesive 19 and before the adhesive 19 has hardened, with a portion of the adhesive 19 being removed from the adhesive channels and/or the receiving space 17 can be displaced. However, the introduction of reinforcing rods 24 into the adhesive channels 23 can also serve to support the filling or filling up of receiving spaces 17 with the adhesive 19 .

The reinforcing rods 24 can essentially be made of the same material or material comprising plastic as the shaft parts 2, 3, 4, 5. The reinforcing rods 24 can be essentially cylindrical, with fundamentally different cross-sectional shapes being possible, for example oval or circular, cuboid, square or triangular cross-sectional shapes, as is also the case in 6 is indicated. A longitudinal extent of a reinforcing bar 24 can also be defined as in Fig.6 illustrates at least essentially a longitudinal extension of the corresponding adhesive channel 23, in which the relevant reinforcing rod 24 is inserted, correspond.

As already mentioned above, as an alternative to the one in the 1 and 2 illustrated embodiment, a rifle stock 1 of a similar shape or of the same shape comprises only three stock parts 2 , 3 , 5 , namely a front stock 2 , a central stock adapter 3 and a rear stock 5 . A corresponding embodiment comprising three shaft parts 2, 3, 5 is for comparison in the 7 shown. The design or manufacture and the connection of the in 7 Shaft parts 2, 3, 5 shown can be at least essentially analogous to the above with reference to Figures 1 to 6 explained embodiment example for a four-part rifle stock 1 are carried out.

Finally, in the 8 a further exemplary embodiment of a modularly assembled or constructed rifle stock 1 is shown. As can be seen, this exemplary embodiment is an embodiment of the rifle stock 1 for a single shot rifle. Again, this embodiment of a rifle stock 1 consists of several shaft parts 2, 5, 25, 26, with the design for a single-shot rifle as based on FIG 8 at least two central shaft adapters 25, 26 can be seen. At the in the 8 illustrated embodiment of a rifle stock 1 for a single-shot rifle, the shaft parts 2, 5, 25, 26 can turn analogous to the above with reference to Figures 1 to 6 described rifle stock 1 configured and connected to each other.

How best by comparing 1 and 8 can be seen at the in the 8 illustrated embodiment of a rifle stock 1 for a single shot rifle the forearm 2 and the buttstock 5 may be the same as in the embodiment according to 1 or 7 . On the other hand, the center shaft adapter 25, 26 can be adapted to the weapon type of a single-shot rifle, and accordingly have a different configuration than the center shaft adapter 3, 4 from the in FIG 1 illustrated embodiment. In particular, according to a rifle stock 1 for a single shot rifle 8 the center shaft adapter 25, 26 can be connected via a tilting joint 27.

The exemplary embodiments show possible variants, whereby it should be noted at this point that the invention is not limited to the specifically illustrated variants of the same, but rather that various combinations of the individual variants with one another are also possible and this possibility of variation is based on the teaching on technical action through the present invention in skills of the specialist working in this technical field.

The scope of protection is determined by the claims. However, the description and drawings should be used to interpret the claims. Individual features or combinations of features from the different exemplary embodiments shown and described can represent independent inventive solutions. The the independent The problem underlying the inventive solutions can be found in the description.

All information on value ranges in the present description should be understood to include any and all sub-ranges, e.g. the information 1 to 10 should be understood to mean that all sub-ranges, starting from the lower limit 1 and the upper limit 10, are also included , ie all subranges start with a lower limit of 1 or greater and end with an upper limit of 10 or less, e.g. 1 to 1.7, or 3.2 to 8.1, or 5.5 to 10.

Finally, for the sake of clarity, it should be pointed out that some elements are shown not to scale and/or enlarged and/or reduced in size for a better understanding of the structure.
