Definitions

  • the invention relates to an adapter for attaching additional devices, such as (night) aiming devices, lighting devices, bipods, grenade launchers or the like, to a firearm, especially a rapid-fire rifle (preamble of claims 1 and 2).
  • additional devices such as (night) aiming devices, lighting devices, bipods, grenade launchers or the like
  • the alignment of the assembly, and thus the aiming device, and thus the achievable shooting accuracy is even more unstable if the corresponding additional device is not directly on the front part of the Wants to attach barrel.
  • This attachment to the barrel is undesirable, at least with precision weapons, because it affects the accuracy of the shot. You would have to attach this device to the handguard, the position of which is even less precise than the position of the plastic housing relative to the barrel.
  • the object of the invention is to remedy these difficulties or at least to alleviate them in part.
  • a sleeve made of metal which has a cylindrical outer surface and in this at least one ring formation, and which can be brought into metallic connection with the barrel of the weapon, such that it surrounds the barrel and the ring formation coaxially or is aligned at least parallel to the barrel, and b) an additional device which can be brought into positionally stable engagement with the sleeve is provided for receiving the additional devices;
  • a sleeve surrounding the barrel of the weapon and securely connectable to it is provided, and ⁇ ) an additional device which can be brought into engagement with the sleeve in a position which is stable in the axial position is provided, with an embodiment which engages in a counter-configuration of the weapon which is complementary to it in the operative position and thereby ensures that the additional device is prevented from rotating relative to the weapon.
  • the sleeve preferably matches the above group of features.
  • the sleeve according to the invention is connected to the barrel in a fixed (claim 2) or even metallic (claim 1) connection, so it is fixed in the best possible position in relation to the barrel. Changes in temperature due to solar radiation are not sufficient to noticeably change this connection.
  • the cylindrical outer surface of the sleeve and its ring groove or ring grooves allow any conceivable rotational position for the additional device.
  • the additional device is fixed in the direction of the axis of the barrel by means of the ring grooves, but not in the mentioned rotational position.
  • the only decisive factor is the length of the cylindrical outer surface of the sleeve and the complementary design of the additional device as well as the accuracy of the seat of the additional device on the sleeve. If these parameters ensure that the additional device does not wobble (or sufficiently little) on the sleeve, i.e. that no angular displacements between the sleeve or the additional device in the direction of the barrel axis are possible, then the additional device is practically completely (or sufficiently) stuck to the barrel ,
  • the training can be made afterwards, for example through a bore, or with a new weapon
  • Purpose are provided to serve as an anti-rotation device. However, it is preferable to choose an existing training.
  • the sleeve Since the sleeve does not have to absorb excessive loads, it can be made of light metal, so that it only makes a minor contribution to increasing the weight of the weapon.
  • the invention is primarily concerned with the development of a rapid-fire rifle, which is preferably designed as a gas pressure loader.
  • the sleeve according to the invention can also easily be attached to a machine gun, a submachine gun, a pistol or the like. be attached. As far as the free swinging of the barrel is not impaired, even attaching to a sniper rifle makes sense.
  • the additional device can preferably be brought into positive engagement with the ring formation (s) and has an inner surface which has at least part of the cylindrical sleeves -External surface is complementary (claim 3). In this way, the fit of the additional device on the sleeve is optimized simply but reliably.
  • the barrel is held in the rifle by means of a union nut that grips a shoulder on the barrel from the front and is screwed into a male thread that is formed in the part that has the fixed locking lugs and is embedded in the plastic housing ,
  • a preferred development of the invention then consists in that the sleeve made of metal, instead of a union nut holding the barrel, is formed with a barrel mounting part and can be screwed to the weapon (claim 4).
  • the barrel is held in the weapon with the sleeve according to the invention as well as with the union nut known per se. Since the sleeve, like the union nut, only sits on one shoulder of the barrel, but not otherwise, the barrel is fastened with the sleeve as well as without this sleeve. The sleeve does not in any way hinder the free-swinging barrel of a sniper rifle.
  • a preferred embodiment of the invention is that one of the ring designs is smaller in size than the other (s) and that the additional device Has engagement training that are suitable for the smaller size (claim 5).
  • the ring formations are ring grooves. So it is ensured in a manner known per se that fixed and floating bearings are provided for the attachment of the additional device in the ring formations.
  • the other (s) is or are one or more (in the direction of the running axis) holder (s) with play, so that the additional device in the case of thermal expansion is a predetermined one for the target accuracy has harmless direction to expand or contract unhindered relative to the sleeve. This avoids thermal tensions and the resulting distortions that could otherwise lead to inaccuracies.
  • this configuration means that practically all harmful heat deformations are avoided.
  • the additional device can then be provided with an increase in surface area, for example ribs, in order to improve the heat dissipation to the outside.
  • the ring formation (s) can be at the level of one or more receiving bores (s) which penetrate or penetrate the additional device.
  • the groove diameter of the ring formation (s) is a little larger than the diameter of the corresponding mounting hole into which a bolt or the like is inserted. It should only be avoided that the additional device sits with such bolts at two points on the sleeve facing away from or facing each other
  • a rapid-fire rifle has a forearm that at least partially encloses the barrel and prevents the shooter from burning his hand on the hot-shot barrel.
  • an additional device may also need to have protection for the shooter's hand.
  • a preferred embodiment of the invention is to design the sleeve made of metal so that it fits into the assembled fore-end (claim 7).
  • a rifle can be set up for the possibility of retrofitting, but without the retrofitting being carried out.
  • a fore-end can also be designed so that it fits over the sleeve according to the invention.
  • a rifle is created in which any additional devices can be attached after removing the forearm. These can be known snow guns as well as snow guns to be newly constructed.
  • the additional device can in particular be part of a grenade launcher (claim 8), which is to be attached, for example, under the barrel and introduces high forces into the rifle, but must always be precisely aligned (because its sight is located elsewhere on the rifle).
  • This grenade launcher benefits from all the advantages of the invention. But a bayonet (for an ordonnance shotgun, for example) also needs the fixed mount that the invention offers.
  • the additional device is a carrier with rails parallel to the running axis is, which are used to attach accessories, aiming and lighting devices, a bipod, a front "pistol grip", a strap bracket or the like. (Claim 9).
  • Such rails are known and have recently proven to be particularly advantageous for quickly and easily attaching lighting devices, target devices and other devices to the weapon. In this way, it has become customary to load existing rails with all possible devices, regardless of how heavy they are, for example night target devices, bipods, lighting devices, especially infrared lighting devices of high power.
  • a carrier preferably has four rails which are arranged around the weapon at the same angular distance from one another, that is to say one rail each pointing upwards, downwards and to the two sides, in relation to the axis of the barrel. Many devices can therefore be attached to the carrier at the same time.
  • the invention ensures that the carrier permanently and reliably carries high loads, these loads being introduced directly into the element carrying the barrel and the locking parts, that is to say the component which is best set up to absorb the force.
  • the carrier like the sleeve, could also be made of light metal. However, since the carrier sits over a considerable length on the cylindrical outer surface of the sleeve, which in turn braces it, it has proven to be particularly advantageous that the carrier is made of hard, dimensionally stable plastic exists (claim 10).
  • This plastic can be reinforced, for example with molded glass fibers, or can be a, preferably reinforced, thermoset. In this way, a simple, cheap, but absolutely accurate manufacture of the carrier is achieved, both in terms of the rails and in terms of the seat on the sleeve.
  • the carrier may consist of two or more parts held together by fasteners such as bolts and nuts. These bolts can also engage in the ring formations, preferably ring grooves.
  • the carrier is preferably in one piece (claim 11). Under certain circumstances, it can be pushed from behind over the removed barrel and the sleeve. However, it is preferably designed such that it has been pushed onto the sleeve from the front over the barrel (with a muzzle fire damper) and (in the case of a gas pressure charger) the gas sampling piece.
  • This sleeve is preferably perforated for the rest, because of the reduction in weight, better cooling and the attachment points formed by the bores for a tool for tightening and especially for unscrewing the sleeve.
  • the invention is also reflected in a method for retrofitting a gas pressure rapid fire rifle which has a barrel which can be removed by loosening a union nut, with an adapter as has just been described.
  • This method has (according to claim 17) the features that the removable barrel is removed by loosening the union nut and replaced by a barrel in which a sleeve is provided instead of the union nut, which forms an extension of the union nut to the front and has a cylindrical outer surface, and that from the front an additional device on the sleeve is postponed, engages for a non-rotatable fixing with a training in a counter training on the rapid-fire rifle and for the axial
  • This method can be used with any rapid-fire rifle, regardless of how it works.
  • the rapid-fire rifle is a gas pressure loader, the barrel of which is drilled for gas extraction and in which a gas sampling piece sits on the barrel, it is particularly advantageous that the additional device is pushed over the gas sampling piece sitting on the barrel and onto the sleeve ( Claim 19).
  • the barrel therefore does not have to be modified or even removed to change the additional device or the gas take-off removed.
  • the additional device can also be divided lengthways and consist of two or three parts, which are placed from the side and connected to each other, for example screwed.
  • FIG. 1 shows the front part of a rapid-fire rifle in longitudinal section, which is provided with an adapter according to the invention
  • FIG. 3 shows the rifle of FIG. 1 on the same scale, in a side view
  • Fig. 4 is a section along line IV - IV in Fig. 1 and
  • a locking piece 3 made of steel is tubular, has the rear end of a barrel 5 in its interior, has locking lugs behind it (no reference number) and is poured into a plastic housing 1.
  • This locking piece 3 forms the central force absorption body of the rifle.
  • the barrel 5 is non-rotatably in the locking piece 3 and has a shoulder 7 which forms the stop on this locking piece 3.
  • the locking piece has a male thread on the outside in its front, free end region (part of a threaded connection 11).
  • the sleeve 9 is made of steel, titanium, light metal or a combination of different materials and is cylindrical in shape. It engages behind the shoulder 7 from the front with a constriction 13 and is firmly screwed onto the male thread of the locking piece 3 with a female thread, forming the threaded connection 11.
  • the sleeve 9 corresponds to the known union nut previously used at this point. However, it is extended towards the front or close to a gas extraction piece 19 which is detachably fastened on the outside of the barrel 5.
  • the support between the shoulder 7 and the constriction 13 ensures an exactly axially parallel and almost coaxial alignment between the overall cylindrical sleeve 9 and the barrel 5.
  • the sleeve 9 has a relatively thin, perforated wall and has two annular grooves 15, 17: a front annular groove 15 with final dimensions and a rear annular groove 17 with excessive dimensions. Because of the small sleeve wall thickness, the annular grooves 15, 17 are formed by indentations of the wall.
  • the sleeve 9 tightly encloses the barrel 5, but without touching it.
  • the threaded connection 11 between the sleeve 9 and the locking piece 3 also does not touch the barrel. Only the mutual seating of barrel shoulder 7 and Sleeve constriction 13 provides axial support for sleeve 9 on barrel 5. There is no contact in the radial direction.
  • the barrel can swing out freely and has the same properties as if only the known union nut were present instead of the sleeve 9.
