Description

Buttboard {SHOULDER STOCK COMPRISING A STORAGE COMPARTMENT}

The present invention relates to a butt stock base, a stock plate and a butt plate comprising at least one storage compartment formed by, for example, a battery.

In terms of positions such as "up," "forward," "vertical," and the like, a weapon is assumed at a normal non-inclined firing position with a horizontal barrel, the butt having a storage compartment.

Rifles often have storage compartments in rear gunstocks or butts, which serve for storage, such as, for example, cartridges such as shotgun barrel and ball cartridges, and storage kits for cleaning kits. Such storage compartments have long been known from the middle of the 19th century to serve for storage purposes such as flint, wadding and the like. At least in the case of a military rifle, for example the US carbine .30 M1 in which the cleaning kit is stored in the storage compartment, the storage compartment is estimated to be waterproof, but to date it has also been at least for mass production The price to bear is not managed. In the case of the so-called US carbine, for example, there is a box in its own storage compartment which is waterproof. The storage compartment is sealed by a cover made of steel, which is embedded in the stock plate and opened after exiting the grip around the hinge located on the boundary. This cover is not waterproof, since even a grommet placed under the cover will be permeable to water because it may be compressed differently from one another on one side. In addition, the cover is difficult to open, which often breaks the nail. Rust further exacerbates this drawback, while broken gripping springs cause the covers to strike each other back and forth, which poses a problem for proper use of the weapon.

The stock plate is screwed into the stock timber, as it has been since at least the mid-18th century. This tradition of screw tightening of stock plates has become a second characteristic for designers to the extent that stock plates are screwed into the butt base or stock even in the case of plastic stock (eg, the Remington rifle "nylon"). .

In this case it is true that there is a weapon with a waterproof ammunition container (Komet-Signalstift) under which the container is covered by a screwed cap under which the gasket is buried. Since it constitutes a relatively small and easily lost part, it has considerable constraints and can only be fixed to the stock plate from another point of view.

Modern automatic rifles and the like often require a so-called battery, which must be housed directly on the rifle or at least be held there. These batteries are particularly moisture-proof when they are coupled to contacts, but should be easily accessible. It is true that these batteries can be stored in separate moisture-proof boxes in storage compartments which do not themselves need to be moisture-proof, but this solution is difficult and expensive. The aforementioned US Carbine .30 M1, whose production began in the 1940s, uses this principle, but is currently priced only as a military weapon for mobile units.

Even if a tubular magazine is needed for launch (patented in 1860 by Spencer; FN-Small Caliber Automatic "Browning"], the tradition of portable firearms is familiar with many solutions such as so-called stock magazines, and if the price is now justified in the case of high-end rifles, they are partly costly Manufactured and even provide very good moisture resistance.

Although there are a number of feasible solution processes, better solutions are contemplated where possible, which are moisture proof, can be easily and repeatedly opened without damage, cost effective and can be opened without tools. If possible, only very few additional parts should be needed for sealing the storage compartment, and the storage compartment should only be opened rearward to have the best possible protection in the case of the use of the rifle. Compliance is essential for mass production with little or no close monitoring.

This problem is solved from the fact that the storage compartment has a liquid tight closure cover formed by a stock plate, and the stock plate is detachably fixed to the rear of the butt base by a bayonet lock. Storage compartments or storage compartments do not have any individual cover, but rather are covered by a stock plate as has already been done in the case of a Swiss military rifle, but in this Swiss military rifle under the stock plate only the name of the person who issued this rifle Only this described label is present. However, the stock plate in the case of the present invention functions for the purpose of the cover and is not a hiding place. However, the fixing of the stock plates on the butt base by the bayonet fasteners destroys all traditions. Nevertheless, this fixation is reliable and permanent. Particularly important here, however, is the fact that this stock plate fixing means leads to carrying out the moisture-proof closure of the at least one storage compartment with the lowest possible number of elements. Ideally, there are fewer parts than in the case of conventional stock plates which require at least two screws but which do not cover any compartment.

The bayonet fastening can, for example, be off center, so that by turning the stock plate a substantially whole cross-sectional area of the butt base can be released, so that a correspondingly large storage compartment can also be created. However, one preferred embodiment of the present invention resides in the fact that the bayonet fastening is formed by a central bolt extending rearward from the base of the butt plate (claim 2). In the case of an automatic rifle, two compartments are created on both sides of the rifle's vertical longitudinal plane, with the gun path or its extension freely maintained. Such storage compartments are ideally suited for the storage of batteries.

In this arrangement, the advantage is obtained that both storage compartments are evenly close to the central bolt, such that the central bolt as a fixed anchor point ensures the sealing of the storage compartment.

According to another refinement, the stock plate preferably has an indentation which holds the center bolt and holds the stock plate in the case of twisting (claim 3). Thus, an existing military rifle or automatic rifle can be retrofitted and the existing rear gunshot base can be raised because all devices for sealing the storage compartment are present in the area of the stock plate behind the rear gunshot base.

According to another embodiment of the present invention, in the case of a closed stock plate, it is particularly preferred that the elastomeric coating is arranged above the storage compartment or all the storage compartments, the elastomeric coating being combined with the boundaries of the storage compartment (claim 4). This elastomeric coating corresponds to a rubber gasket for sealing a cylindrical threaded sleeve, but the invention is of course not limited to a cylindrical storage compartment. In addition, this elastomeric coating ensures sealing when a certain play occurs in mass production, which is only sealed by a compressible gasket.

Stock plates are traditionally composed of metals, but there is an increasing tendency to use rubber or elastomer plates, because the rubber or elastomer plates not only adhere better to clothing and cushion recoil, but in particular to objects This prevents the erect rifle from leaning against the wall or from slipping over. In this process, a particular problem exists in the case of the hollow plastic butt base, that the stock plate is not uniformly supported by the butt base. For this reason, the stock plate is preferably composed of a rigid coating and an elastomeric coating mounted after the rigid coating (claim 5). The rigid coating may further form a molded part of the bayonet fastening of the present invention, and the back elastomeric coating is suitable for forming a coating for the support of the inorganic.

Thus, the rigid coating preferably has an indent that fits over the center bolt, preferably with a recess arranged in the case of a closed stock plate over each storage compartment or in all the storage compartments in the rigid coating, and within the recess. Is an elastomeric coating (claim 6). In this process, the rigid coating can be cast in a simple and economical manner, for example zinc or plastic, and then a sealing elastomeric coating can be provided.

In this process, it is particularly preferred that the recess or recesses are continuous and the elastomeric coating is formed by an elastomeric coating forming the rear part of the stock plate (claim 7). The back elastomeric coating easily protrudes through a recess that is only a hole and seals the storage compartment. In this process, the elastomeric coating is rigid to still exhibit the properties of the elastomeric coating, but is selected to be rigid to provide the necessary strength for sealing. As an example, elastomeric materials as used for automobile tires are suitable.

In principle, it is enough that a central bolt guides and holds the stock plate. However, in order to prevent a material such as straw or the like between the stock plate and the butt base, at least one molding is preferably provided projecting rearward on the boundary of the butt base, which is a rigid coating of the stock plate. It is proposed to combine with (Claim 8). This hook-shaped part preferably combines with the rigid coating in positions furthest from the central bolt, ie above and below.

According to another embodiment of the present invention, the protruding molded part or the at least one protruding molded part has a capture molded part, and the capture part may fall into the capture molded part, and the capture part is formed on an elastomeric coating, and the elastomer The coating preferably forms the rear part of the stock plate (claim 9). In this way, the stock plate is placed firmly and unstable, ensuring that the launching is not hindered, or that the elastomeric coating is not peeled off by the movement of the elastomeric coating on the storage compartment and / or the sealability is not compromised. Since the portion of the catch can be formed in a single piece with the elastomeric coating of the butt base or stock plate, no additional manufacturing cost is required.

In this process, it is particularly preferred that the catch has a handle protruding at right angles to the stock plate, which handle can engage into the catch form in a fastening manner and can be lifted out of the catch form (claim 10). Thus, the catch can be released without a tool, but additionally remains closed upon firing because the shoulder presses the handle into the catch.

Preferably, the butt base is made of plastic (claim 11). As a result, the storage compartment is particularly water resistant because water cannot penetrate through the lateral walls of the butt base even when exposed to rainy weather. In addition, very complex moldings can be made ready for use in a single operation. Machining time per workpiece is reduced to a few seconds.

Preferably the elastomeric coating and the rigid coating are fixed to one another, molded or vulcanized and the rigid coating consists of plastic (claim 12). Thus, elastomeric coatings and rigid coatings can be produced by injection molding with great precision even when they have to have different thermal expansions, and can be precisely fixed to each other.

Particularly preferably the bayonet fastenings, forming (s) and / or rigid coatings are at least in the stock plate at least in the final rotational area of the stock plate when secured to the butt base, for example via an inclined guide rib or path on the central bolt. Is constructed in such a way that it is pressed against the butt base (claim 13). As a result, the stock plate can be easily placed in a simple manner, but then it is ensured that access to the butt base at the time of rotation, and the elastomeric coating are also brought together above the storage compartment in such a way as to compensate for very large tolerances through this pressurization together. Is pressurized. Thus, any resulting flashes, gaps, etc., are sealed with the elastomeric material of the elastomeric coating. Even in the crudest manufacturing, the sealing of the storage compartment is always guaranteed.

Thus, a butt is produced, which has fewer parts than in the case to date, and nevertheless has one or more storage compartments in the butt base, and which is completely sealed even during the production during coarse war.

Another advantage of the present invention lies in the fact that plates having different shapes (convex or concave) can be exchanged in an instant.

The subject matter of the present invention will now be described in more detail with the aid of drawings through exemplary embodiments. The figure shows the following.

1 is a side view of the butt of the present invention,

2 is a longitudinal cross-sectional view of the butt plate of FIG. 1;

3 is a plan view of the buttboard,

4 is a perspective view of the butt base, with the stock plate removed;

5 is a view of the butt base seen from the rear;

FIG. 6 is similar to FIG. 1 but without the stock plate, FIG.

7 is a longitudinal sectional view through a stock plate;

All figures show the same embodiment. Therefore, they are not described in detail.

The butt base 1 is injection molded from plastic and terminates in a rather vertical surface of the plane defined by the lower and upper forming parts 15, 11 protruding rearwardly. On this planar surface are joined two storage compartments 23 with both rounded cross sections arranged on both sides of an imaginary vertical center line connecting the upper and lower shaping parts 11 and 15 to each other.

The lower and upper shaping parts 15, 11 are configured in the shape of hooks with cross sections turned relative to each other so that they receive and hold the rigid coating 5 of the stock plate 3. The upper shaping portion has a diagonal inlet surface 13, and on the upper side (FIG. 4) there is an indentation 19 and a groove 31 in which the capture finger 17 (FIG. 2) can fall.

At approximately the center of the butt base 1 this center bolt 9 extends rearward and beyond the planar surface and is disposed on a vertical centerline, but not exactly on the horizontal centerline, this center bolt 9 guides to the left and right. Rib 21 (FIG. 4) is provided. The central bolts 9 are arranged adjacent to them below the storage compartment 23.

Rigid coating 5 has an indent 25, which is configured as a through hole and has extensions up and down, so that indent 25 is a rigid coating for the view of FIG. 1 or 2. When (5) is rotated 90 degrees out of the image plane, it can slide over the center bolt 9 and its guide ribs 21. The guide ribs vary in width so that incorrect placement of the plate (stock plate) is not possible.

When the rigid coating 5 is pivoted back to that position shown in FIG. 1, its upper and lower ends enter the hooked upper and lower forming portions 11, 15. The ridges of the rigid coating 5 assigned to the shaping portions 11, 15 and the outer surface facing the rear of the guide ribs 21 are configured as inclined edges 29, likewise also correspondingly if necessary. The surfaces of the shaping parts 11 and 15 and the guide ribs assigned to are directed forward. Thus, the rigid coating 5 is firmly pressed against the planar rear face of the butt base 1.

An elastomeric coating 7 (FIG. 7) is fixed on the rear side of the rigid coating 5, which has a capture finger 17 on the top side, which is directed upward. The upper shaping portion 11 has a rearwardly directed groove 31 that engages the indentation 19 extending upwardly open. The capture finger 17 of the elastomeric coating 7 extends and pivots with the rigid coating 3 relative to the diagonal inlet surface 13 of the upper forming 11 upwards into the final position (FIG. 1), It rises again and finally falls into the groove 31. For release, when the tip of the catching finger 17 in the indentation 19 can be grasped and it can exit the groove 31 and turn the rigid coating 5 secured to the elastomeric coating 7 again horizontally. It slides back somewhat until flexible.

The elastomeric coating 27 is guided by the rigid coating 5 so that the elastomeric coating slightly protrudes onto this rigid coating to act as a sealing element. As an alternative, a thin elastomeric coating can be fixed in the region of the rigid coating 5 which is returned to the storage compartment 23, in which the rigid coating has a rigid coating 11, 15 with respect to the butt base 1. Are pressed together when pressed into the diagonal surface 13 of. The storage compartment 23 is now fully sealed.
