Abstract

The invention relates to a firearm comprising a flat metal surface (9) on which a barcode (11) is placed which serves to record information and, at the same time, to camouflage. This barcode is incorporated into the metal in such a manner that the lines or the spaces of the barcode (11) are formed by fine grooves or ribs. This firearm is preferably designed as a self-loading pistol having a plastic grip (1), and the barcode (11) is placed on at least one side of the bare slide or breech (3). The invention also relates to a method for producing a firearm of this type. This method involves burning the barcode into the flat metal surface by means of a laser treatment.

Description

, Firearm and a Method for Its Production The invention relates to a firearm with an even metal surface, in accordance with the preamble of claim 1, as well as a procedure for its production, in accordance with the preamble of claim 4.
In the second half of the 19~" century, it was common to engrave, chisel or brand into the metal or wood of hand guns not only serial numbers and the name of the manufacturer, i.e. model-related identifying information, but also individual identifiers like names and dedications, but especially formation and operating instructions in the case of military weapons. On standard-issue weapons, it is sometimes possible to find an entire list of formations, via which the military track of the weapon can be read from its introduction to its discharge.
Chiseling or branding takes up a lot of room without a lot of characteristics being identifiable. But, it does have the advantage of permanence. Moreover, the use of individual chisel or branding letters does not require an even surface. This also applies to engravinct, but this is extremely complicated. Moreover, the cuts with the engraver can lead to undesirable stress concentrations on heavily loaded, thin parts. Thus, engraving is usually only performed on expensive civilian weapons.
More recently, so-called electrowriters were sometimes used to introduce notations. This allowed, even with modern, filigree weapons, e.g. with an automatic pistol, the introduction of notations without the weapon being dismantled into individual parts, compressed by the stamping, or heat-damaged by charges.
In recent times, information that contains manufacturer and sales information is applied in the form of a barcode. Such a barcode consists of a row of parallel bars with different widths andlor at different distances from each other and is attached to a contrasting base, which in turn is affixed to the weapon packaging or the weapon itself. It is usually read with a reader device that can decode the barcode without problems. The layperson cannot read the information on the barcode without a reader.
As a general rule, the barcode must be applied to a more or less even surface.
In terms of the invention, a surface is "even" if it is even enough to allow the quick and trouble-free reading of a barcode applied to it.
Of course, this type of barcode is rather easy to remove or damage such that it can no longer be read.
A handgun has recently been suggested (DE 100 62 239 A1), in which, unbeknownst to the user of the weapon, a barcode is introduced into the millings for the engagement of the slide. Only millings that are clearly undamaged can be seen, because they have omissions.
However, this barcode is relatively short and can only accept a few end numbers of the weapon number. In US 6 432 559, information carriers are so molded or ingrained into the weapon parts that the information cannot be read from the outside.
Regardless of this, the problem is known that the surfaces of military weapons should be as inconspicuous as possible, i.e. non-reflective and with unclear contours.
Insofar as a military weapon has a smooth, level surface, then it should be designed as matte as possible. But they must not be too roughly processed, since otherwise material inaccuracies and errors can creep in or remain undetected. tJp until now, this problem has been poorly solved by first producing the surface with the technically offered accuracy and then reworking this surface, which is quite time-consuming. The reworking is usually performed chemically so as not to stress the material parts, which are often designed as thin as permissible in order to minimize the weight of the weapon.
Based on this overall problem, the object of the invention is to improve the initially named handgun to the effect that it has permanent, easily readable identifying information and that it is less easily recognizable.
This object is solved according to the invention such that a barcode i:a attached to this even metal surface and is worked into the metal such that the bars or the spaces between the bars of the barcode are formed by fine grooves or bars (claim 1).

3a The attachment of the barcode is not new, but its insertion in the metal surface is. It was not to be expected from the outset that this type of barcode expected from the outset that this type of barcode would be readable since the contrast color is missing.

However, it turned out that the different reflection with malleable or, better, negatively formed bars enables a reliable reading, even though there is no color contrast. It does not matter how deep the bars or spaces are. In fact, they can be relatively flat. Nevertheless, the proper reading is surprisingly possible.
At the same time, the barcode forms a raised surface that is arranged within the metal surface and thus prevents its reflection and also changes its contours.
While the mechanical raising of a surface section for the purpose of reducing the reflection and blurring of the contours is too time-consuming to be used in the mass production of standard-issue weapons and while the insertion of a barcode into an even metal surface is also too time-consuming for the same reasons, one and the same barcode surface here is used for two completely contrasting purposes, which surprisingly ensures a positive balance of costs: too complicated for each of the individual purposes, an engraved or otherwise constructed barcode surface is sufficiently economical for both purposes together.
Preferably, the barcode takes up a surface that takes up a palpable share within the level surface and/or subdivides this level surface (claim 2). Thus, the optical effect of the barcode surface is optimized such that it optimally serves to camouflage the inherently conspicuous level surface.

As a general rule, this barcode surface is suitable for any firearm. But since the size of a meaningful barcode surface is limited, the size of the level surface that can be effectively camouflaged by this barcode surface is also limited. For this reason, the firearm is preferred as an automatic pistol with a plastic handle and the barcode is applied or worked into at least one side of the open slide (claim 3).
In the case of a hand firearm with a handle that is made of plastic or coated with plastic, a barcode cannot be inserted permanently enough into the handle; above all its material property is insufficient for the fine separation of the bars or grooves of the barcode.
On the other hand, a barcode attached to the open-lying slide can be read easily and problem-free using a reader device.
The slide surface ultimately offers a conspicuous surface that is exposed to the highest mechanical stresses. For this reason, the welding or the milling out of the barcode means a high thermal or mechanical impairment of the strength of the slide that is not easily acceptable. The permanence of the once attached barcode is guaranteed in this manner.
The aforementioned type of barcode can generally be inserted in different ways, e.g. through engraving. But, it turns out that the barcode is preferably branded into the even metal surface through a laser treatment (claim 4).

The, at first, very complicated laser device can be controlled fully electronically and automatically so that the text of the barcode is removed from the arbitrariness of the operating personnel and is performed without error. The branding is extremely gentle on the material since the heating of the metal of the level surface only reaches a very low level, so that the material is only damaged in a defined and specific manner over a shallow depth. This material depth lies within the tolerance field of the material thickness. The formation of the bars or grooves takes place with the highest precision, but is nevertheless very quick. The cost for a branding procedure is very low so that the high costs of the appropriation of the laser device are quickly amortized.
The subject matter of the invention is represented in the attached exemplary drawing, in which the single figure shows a top view of the left side of a standard-issue weapon.
If this pistol is held properly for a horizontal shot, then the direction of fire points "forward" (to the left in the drawing) and the "top" and "bottom" result from the natural position of the weapon (also top and bottom in the drawing).
The bottom part of this pistol has a handle made out of reinforced plastic, into which an outwardly open metal plate (not shown here) containing the serial number and, if applicable, firing characters is embedded.

The surface of the handle is practically designed (fish scales, raisings, even with national emblems if so desired by quantity buyers).
A slide or lock 3 made of specially treated steel is attached in a moveable manner to the top of the handle 1, as is generally known. The front part of this lock 3 has manufacturer identifiers, firing characters, etc.; the back part contains holds 5 so that the shooter can securely grip the lock 3 for reloading. An ejection window 7 is located on the top.
The front and back parts of the lock are thus sufficiently raised or designed in order to avoid reflections. The middle part of the lock 3 looks different. The back part of the ejection window 7 is located here, i.e. the position receiving the highest amount of stress during firing. Here, the lock 3 has a smooth, level surface 9, which can reflect a ray of light. This surface 9 could be reworked, but this must be done very carefully since each sharp-edged cut in the steel can cause breakages. Namely, as already mentioned, the occurring stress is highest here.
A large part of this surface 9 is now take up by a barcode surface 11, which is shown hatched here to simplify matters.
This barcode surface 11 has a barcode that is branded in relatively finely and evenly using a laser. This ensures that no undefined sharp edges can be formed in the barcode. Moreover, due to its fineness, the barcode accommodate a longer message.
The barcode surface 11 breaks and distorts the surface 9 so that it can no longer be recognized as the surface of a weapon, even if parts are still recognizable.
Since here the barcode is both a message carrier as well as a raising, its relatively high costs are still justifiable.
