Ergonomic butt plate according to claim 1.

Description

The invention relates to an ergonomic butt plate, which combines several functions in their execution and is attached to a shaft or a fold-out, extendable shoulder rest of a weapon and in their shape and position relative to the shaft for the user and the respective discipline or type of attack can be customized.

A butt plate is the interface between the shaft, so the weapon and the shooter. For a secure and repeatable stop, the positive engagement of the butt plate with the shooter's shoulder is decisive. Further, the shape and construction of the butt plate determines the speed of the strike, or possible irritation from entanglement in garments and pressure on the shoulder, which can lead to "shooting fears".

Therefore, a butt plate can contribute decisively to the precision and speed of the shooting result.

Shoulder rests or butt caps of conventional design follow from the outer dimensions rather the shape of the shaft but not optimal the fullness of the necessary functions.

There are shoulder rests z. B. for shotgun, which are relatively little contoured at the contact surface for the shoulder, so you do not get stuck on the clothes. But they transfer rather a point or line load and thus higher loads on the shoulder. Especially for shotgun shooting, there are rubber butt caps with a hard plastic inlay to support the "sliding in" the shoulder - but also not optimal. The variants, which are predominantly known in various rubber designs, have the disadvantage that a positionally accurate stop, especially at height in the shoulder, is hardly repeatable or requires time-consuming and concentration-consuming corrections. Another disadvantage of the rubbers is the anti-slip effect, which entails hanging in the clothes or shifting the clothes, which also leads to irritation. Then there are strongly concave shapes and multi-part aluminum constructions, which ensure a good support function and repeatability of the attack by their wedge-shaped design but are mainly suitable for quasi-static disciplines, because even here the risk of getting stuck in the clothing at a quick stop is great. Butt caps, which include various exposed shoulder hooks at their lower end, are also a disturbing element in dynamic disciplines and disciplines with position changes.

In the usual shoulder rests and butt caps depending on the shape of various functions are excluded and are therefore not optimal.

The indicated in claim 1 invention is based on the problem of inventing an ergonomic multi-functional butt plate, the best possible symbiosis of o. G. Functions represents.

This problem is solved with the features listed in the claim. Preferred embodiments of the invention are indicated in the dependent claims.

For the location designation, such as "top", "bottom", "front", "rear", etc. is assumed by a weapon in the normal, unverkanteten stop with horizontal run, in which the muzzle "front" represents and "rear" direction Shank end shows.

The ergonomic, multifunctional butt plate according to the invention is characterized in that the positive connection with the shoulder can be designed individually by, for example, making an impression, cast or 3D scan of the relevant shoulder area with or without clothing. The width in the view from the back is selected between 15 mm to 60 mm, preferably in the width of the original shaft. This ensures that the shoulder over the largest possible area in contact with the butt plate, which reduces the pressure on the shoulder.

With the butt plate of the present invention, the concave form-fitting portion that is in contact with the shoulder immediately during the impact can be positioned so that the eye point optimally fits the line of sight and enables a quick stop with a minimum of break point corrections. This ergonomic shape allows quick and safe positioning of the butt plate with the shoulder, giving a speed advantage.

The smooth design of the positive, concave portion of the ergonomic butt plate according to the invention results in an automatic centering in the shoulder compared to the known prior art, which also benefits the precision and speed of the attack.

The ergonomic butt plate according to the invention is further characterized in that in the upper region of the butt plate a forward and upwardly extended, rounded cusp is integrated, which in comparison to the currently known prior art, a safe and fast striking the weapon in the shoulder without in the Clothing is allowed to hang. This ergonomic design in the upper area offers particular advantages in dynamic, time-critical disciplines such as in the disciplines of sports and hunting or official use.

A preferred form in the embodiment of the invention is that in the lower part of an extension is integrated, the functional as a shoulder hook an excellent height limitation in a quick stop provides, however, avoids a danger of getting caught in the clothing compared to conventional designs.

In the case of the ergonomic butt plate according to the invention, the contact surface with the shaft is made flush so that assembly and disassembly, possibly with an adapter, is possible over a wide range of commercially available shanks and shoulder supports.

The butt plate of this invention has the potential to prevent mounting points such as e.g. As for screws and the integration of the respective mounting hardware, such as screws and their accessibility through holes for screwdrivers or Allen key, etc. provided and specific to the weapon can be designed.

Another feature of this ergonomic buttplate invention is the applicability of accessories - for example, a Erddorns, as used in conjunction with bipeds, in the lower part of the butt plate.

A particularly advantageous embodiment of the ergonomic butt plate according to the invention is to produce the shaping outer contour of fiber composites, which offers the greatest freedom in terms of a 3D adaptation to personal body shapes and preferences. Regarding material properties such as weight-related stiffness and strength and its shape design, it is recommended to carry out the shaping contour in CfK carbon fiber reinforced plastic.

When choosing CfK for the shaping outer contour of the ergonomic butt plate according to the invention results from the design of the surface that rests on the shoulder or clothing, if the butt plate should preferably slide well with a smooth surface or more security against slippage, with a rough surface.

If the shaping outer contour, seen from the side view, made of thin-walled preferably provided with a material thickness between 0.5 mm to 2 mm fiber composites (measured radially) results in excellent recoil damping due to the inherent damping of the material. It acts like a complex leaf spring.

Another particular development of the ergonomic butt plate according to the invention in the embodiment as described above in fiber composite material is that the cavity is filled with an elastomer to make the characteristic of the recoil with different E-modules and possibly cast-in cavities or recesses individually. A side effect of the additional mass is a reduction of the impulse on the shoulder. The elastomer in the interior of the outer shape giving fiber composite structure also represents an energy absorption.

This inventive ergonomic butt plate can be mounted on classic shafts with easily accessible mounting points. For some shafts an adapter is required, which can be fitted, vulcanized or produced by casting and can be made adjustable depending on the height and side. The originality of the original shaft is not changed. Thus, this system according to the invention is rückbaubar.
