Definitions

• the invention relates to a firearm with a flat metal surface, according to the preamble of claim 1, and a method for its production, according to the preamble of claim 4.
• bar code a so-called bar or bar code
• Such a bar code consists of a line of lines parallel to one another with different widths and / or different distance, which is applied on a contrasting pad, which in turn is glued to the packaging of the weapons or the weapons themselves.
• the reading is usually carried out by means of a reader that is able to decrypt the barcode without errors.
• the reading of the information of the barcode without a reader is not possible for the layperson.
• the barcode usually has to be stuck on a reasonably flat surface.
• "Flat” in the sense of the invention is a surface if it is flat enough to allow a barcode attached to it to be read quickly and without interference.
• a handgun has also recently been proposed (DE 100 62 239 AI), in which a bar code is inserted into the milled recesses for engaging the carriage, which is unknown to the user of the weapon. There are only millings that are obviously faulty because they have omissions. However, this bar code is quite short and can only include some final digits of the weapon number.
• the problem is known that the surfaces of military weapons should be as unobtrusive as possible, that is to say not reflective and with indistinct contours. If a military weapon has a smooth, flat surface, it should be made as matt as possible. However, they must not be roughly processed, otherwise material inaccuracies and errors can creep in or remain unnoticed. So far, this problem has been solved rather poorly by first producing the surface with the technically required accuracy and then reworking this surface, which is quite complex. Post-processing is usually carried out chemically, so as not to stress the parts of the material, which are often made as thin as just allowed to save weight.
• the invention has for its object to improve the firearm mentioned in such a way that it has permanent, not easily readable identifiers and that it is less easily recognizable.
• the barcode forms a roughened surface that is arranged within the flat metal surface, thus preventing its reflection and also changing its contours.
• the barcode preferably occupies an area which occupies an obvious portion within the flat surface and / or divides this flat surface
• the firearm is preferably designed as a self-loading pistol with a plastic handle, and the barcode is applied or incorporated on at least one side of the exposed slide (claim 3).
• a barcode attached to the open carriage is easy and easy to read using a reading device.
• the slide surface offers a striking surface that is exposed to the highest mechanical loads. For this reason, welding or milling out the bar code means a high thermal or mechanical impairment of the strength of the slide, which will not be readily accepted. This ensures the durability of the barcode once it is inserted.
• a barcode of the type mentioned above can in principle be introduced in various ways, for example by engraving.
• the barcode is advantageously burned into the flat metal surface by laser treatment (claim 4).
• the initially very complex laser device can be controlled fully electronically and automatically, so that the text of the bar code eludes the arbitrariness of operating personnel and is carried out without errors.
• the baking is very gentle on the material, since the heating of the metal of the flat surface only extends to a very shallow depth, so that the material is defined and determined to be damaged only over a short depth of material. This material depth is within the tolerance range of the material thickness.
• the webs or grooves are formed with the highest precision, but nevertheless very quickly. The costs for a baking process are very low, so that the high costs of providing the laser device are quickly amortized.
• the object of the invention is illustrated in the attached exemplary drawing, in the single figure of which a top view of the left side of an ordnance gun is shown.
• the lower part of this pistol has a grip made of reinforced plastic, into which an exposed metal plate (not shown here) is inserted, which bears the serial number and, if applicable, a bullet.
• the surface of the handle is designed appropriately
• a slide or closure 3 made of specially treated steel is slidably mounted, as is generally known.
• this breech 3 has manufacturer identifications, bullet marks and the like, in the rear part there are handles 5 so that the shooter can safely grip the breech 3 for loading.
• the front and rear part of the closure are thus sufficiently roughened or designed to avoid reflections.
• the situation is different with the middle part of the breech 3.
• the rear part of the ejection window 7 is located there, that is, the point at which the highest loads occur during the shot.
• the closure 3 has a smooth, flat surface 9 which can reflect a light beam. This surface 9 could be post-treated, but this must be done with great care, since every sharp cut in the steel can cause a break.
• the loads that occur are highest there, as already noted.
• This barcode area 11 has a barcode which is burned in relatively fine and flat by means of a laser. This ensures that no undefined sharp edges can form in the barcode. Besides, is due to its delicacy, the barcode was able to record a longer message.
• the barcode surface 11 breaks and deforms the surface 9, so that even if parts should still be recognizable, it is no longer recognizable as a weapon surface.
