Description

i 151358in 151358

Den foreliggende opfindelse angår en øvelsesindsats til med aftageligt bundstykke forsynede skydevåben og af den i krav Vs indledning angivne art.The present invention relates to an exercise effort for detachable firearms and of the kind specified in the preamble of claim V.

Ved øvelsesskydning med fx rifler af repetergeværstypen eller lig-5 nende skydevåben er udgifterne til ammunition en væsentlig udgiftspost. Dette faktum er en betydlig ulempe for dem, der ved flittig træning ønsker at forbedre deres dygtighed til håndtering af skydevåben.In practice shooting with, for example, rifle-type rifles or similar firearms, the cost of ammunition is a significant expense. This fact is a major drawback for those who, through diligent training, want to improve their skill at handling firearms.

Man kan naturligvis i stedet øvelsesskyde med fx et luftgevær, hvis 10 ammunition kan købes meget billigt, men dette indebærer dog den ulempe, at man ikke kan øve sig med det skydevåben, man ønsker at beherske bedre.You can, of course, practice shooting with an air rifle, for example, if 10 ammunition can be bought very cheaply, but this does involve the disadvantage that you cannot practice with the firearm you want to master better.

Der kendes øvelsesindsatse med et øvelsesbundstykke, der kan udskiftes med et skydevåbens normale bundstykke, og en øvelsespibe, 15 der er udformet til at kunne indføres i skydevåbnets pibe. Disse kendte øvelsesindsatse formindsker skydevåbnets kaliber, medens der fortsat anvendes ammunition med en krudtladning.Exercise inserts are known with an exercise bottom piece that can be replaced with the normal bottom piece of a firearm, and an exercise pipe 15 designed to be inserted into the firearm's pipe. These known exercise efforts reduce the caliber of the firearm while using ammunition with a gun charge.

Ved den foreliggende opfindelse tilvejebringes en øvelsesindsats, der muliggør, at et med bundstykke forsynet skydevåben, der normalt er 20 beregnet til ammunition med krudtladning, også kan anvendes til øvelsesskydning med projektiler, som kan fremdrives af trykluft eller trykgas på samme måde, som det sker i luftgeværer.The present invention provides an exercise effort that allows a firearm-equipped firearm, normally designed for gun-loading ammunition, to also be used for projectile shooting with projectiles propelled by compressed air or compressed gas in the same manner as it occurs. in air rifles.

Dette opnås ved de i den kendetegnende del af krav 1 angivne ejendommeligheder. 1 2 3 4 5 6 Øvelsesindsatsen ifølge opfindelsen har den store fordel, at man ved 2 anvendelse af denne indsats kan foretage øvelsesskydning indendørs 3 med skydevåben, som normalt kræver anvendelse af en udendørs 4 skydebane. Endvidere bliver den ammunition, der anvendes ved 5 øvelsesskydningen, væsentligt billigere, idet øvelsespiben kan have en 6 sådan kaliber, at den muliggør anvendelse af almindeligt i handelen værende projektiler af den type, der anvendes til normale luftgeværer. Derved bliver øvelseskydning med skydevåbnet betydeligt mindre omkostningskrævende end normalt.This is achieved by the properties specified in the characterizing part of claim 1. 1 2 3 4 5 6 The exercise effort according to the invention has the great advantage that, with the use of this effort, exercise can be done indoors 3 with firearms, which usually requires the use of an outdoor 4 shooting range. Furthermore, the ammunition used in the 5 shooting is considerably cheaper, since the drill pipe can have a 6 caliber to allow the use of commercially available projectiles of the type used for normal air rifles. This makes practice shooting with the firearm considerably less costly than usual.

2 151358 [ det følgende vil en udførelsesform for øvelsesindsatsen ifølge opfindelsen blive nærmere beskrevet under henvisning til tegningen, på hvilken fig. 1 skematisk viser en øvelsesindsats ifølge opfindelsen monteret i 5 et gevær set fra siden og delvis i snit, fig. 2 viser øvelsesindsatsens bundstykke i større målestok set fra siden og i snit, og fig. 3 viser øvelsesbundstykkets håndgreb i større målestok set fra siden og i snit.In the following, an embodiment of the exercise insert according to the invention will be described in more detail with reference to the drawing, in which FIG. 1 is a schematic view of an exercise insert according to the invention mounted in 5 a side view and partially sectioned rifle; FIG. 2 is a side elevation and sectional view of the bottom of the exercise insert; and FIG. Figure 3 shows the handle of the exercise base on a larger scale, seen from the side and in section.

10 Det i fig. 1 viste gevær 1 er forsynet med en øvelsespibe 2 og et øvelsesbundstykke 3.10 The embodiment of FIG. 1, the rifle 1 shown is provided with an exercise pipe 2 and an exercise bottom piece 3.

Øvelsespiben 2 er udformet således, at den passer ind i det pågældende gevær l's løb 4, og den er i det foreliggende tilfælde også forsynet med to knaster 5, der bevirker en aksial fiksering af øvel-15 sespiben 2. Dette lader sig gøre ved, at geværet l's pibe 6 har en udsparing, som på kendt måde muliggør den nævnte fiksering af skydevåbnets normale bundstykke. Endvidere er øvelsespiben 2 forsynet med et magasin 7.The exercise bar 2 is designed to fit into the barrel 4 of the rifle 1 in question, and in the present case it is also provided with two lugs 5 which cause an axial fixation of the training bar 2. This is possible. that the gun 6 of the rifle 1 has a recess which in a known way enables said fixation of the normal bottom of the firearm. Furthermore, the drill pipe 2 is provided with a magazine 7.

Øvelsesbundstykket 3 har en bageste del 8, en forreste del 9, en 20 ventilmekanisme 10 og et håndtag 11. Fig. 1 og 2 viser øvelsesbundstykket 3 i ladt eller spændt tilstand. Den bageste del 8 og den forreste del 9 er forbundet med hinanden ved hjælp af en skrue 12, så den bageste del 8 kan glide langs skruen 12. Skruen 12 omgives af to fjedre 13 og 14, hvis funktioner senere vil blive forklaret. Endvi-25 dere er ventilmekanismen 10 fastskruet på den forreste del 9. Håndtaget 11 er ved hjælp af et rør 15 forbundet med et kammer 27 i ventilmekanismen 10. Den forreste del 9’s mod øvelsespiben 2 vendende forparti er udformet, så det passer ind i øvelsespiben 2's bagparti. Det kan være hensigtsmæssigt at forbedre tætningen i 30 anlægsområdet mellem øvelsesbundstykket 3 og øvelsespiben 2 ved hjælp af fx tætningsringe 16 og 17.The exercise floor piece 3 has a rear portion 8, a front portion 9, a valve mechanism 10 and a handle 11. FIG. 1 and 2 show the exercise floor piece 3 in the loaded or tensioned state. The rear part 8 and the front part 9 are connected to each other by means of a screw 12, so that the rear part 8 can slide along the screw 12. The screw 12 is surrounded by two springs 13 and 14, the functions of which will be explained later. Further, the valve mechanism 10 is screwed onto the front portion 9. The handle 11 is connected by means of a tube 15 to a chamber 27 of the valve mechanism 10. The front portion of the front portion 9 facing the drill pipe 2 is designed to fit into the drill pipe. 2's rear portion. It may be convenient to improve the seal in the abutment area between the exercise bottom piece 3 and the exercise pipe 2 by means of, for example, sealing rings 16 and 17.

3 151358 Håndtaget 11 er indrettet til at rumme en beholder 18, som kan afgive en eller anden til fremdrivning af et projektil 19 passende gas, fx CC^. Beholderen 18 kan indsættes i håndtaget 11 derved, at man fjerner en tætningsprop 20. Tætningsproppen 20 er forsynet med en 5 stift 21, hvis opgave er at punktere beholderen 18 ved iskruning af proppen 20, så gassen kan strømme ud af beholderen. Proppen 20 er endvidere forsynet med en tætningsring 22.The handle 11 is arranged to accommodate a container 18 capable of delivering gas suitable for propulsion of a projectile 19, e.g. The container 18 can be inserted into the handle 11 by removing a sealing plug 20. The sealing plug 20 is provided with a pin 21, the task of which is to puncture the container 18 by ice-screwing the plug 20 so that the gas can flow out of the container. The plug 20 is further provided with a sealing ring 22.

Øvelsesbundstykket 3 er endvidere tilpasset, så det kan udskiftes med et i geværet 1 normalt hørende bundstykke. Den nødvendige 10 manøvrering af øvelsesbundstykket 3 ved ladning af geværet 1 bliver således den samme som ved anvendelse af geværet l's normale bundstykke, og øvelsesbundstykket 3 påvirkes af geværet 1's aftrækkermekanisme på samme måde, som geværet l's normale bundstykke påvirkes af denne mekanisme.Furthermore, the exercise base 3 is adapted so that it can be replaced with a base piece normally associated with the rifle 1. Thus, the necessary maneuvering of the drill bottom 3 when loading the rifle 1 becomes the same as using the normal bottom piece of the rifle 1, and the drill bottom 3 is affected by the trigger mechanism of the rifle 1 in the same way that the normal bottom piece of the rifle 1 is affected by this mechanism.

15 Ved ladning af geværet 1 sker følgende. Først trækker man på sædvanlig måde ved hjælp af håndtaget 11 øvelsesbundstykket 3 i retning mod sig, hvorved et i magasinet 7 beliggende projektil 19 falder ned i øvelsespiben 2's løb 23. Derefter fremføres øvelsesbundstykket 3 til anlæg mod øvelsespiben 2, hvorved den bageste del 8's fremføring 20 hindres ved, at en flade 24 på en ved den bageste del 8 anbragt skinne 25 kommer til at ligge an mod en del af geværet 1's aftrækkermekanisme. Dette medfører, at den bageste del 8 indtager stilling A, og fjederen 13 bliver derved sammentrykket. Ved den ovennævnte fremføring af øvelsesbundstykket 3 bliver det i løbet 23 nedfaldne 25 projektil 19 af den forreste del 9's forparti ført noget længere ind i øvelsespiben 2, dvs. til den i fig. 1 viste stilling.15 When loading the rifle 1, the following happens. First, in the usual manner, by means of the handle 11, the drill bit 3 is pulled towards it, whereby a projectile 19 located in the magazine 7 falls into the barrel 23 of the drill pipe 2. 20 is prevented by a surface 24 of a rail 25 located at the rear portion 8 abutting a portion of the trigger mechanism of the rifle 1. This causes the rear part 8 to take position A and the spring 13 is thereby compressed. In the aforementioned advance of the exercise base 3, the projectile 19 of the leading portion 9 of the front portion 9 which has fallen down in the 23 is dropped somewhat further into the exercise pipe 2, ie. to that of FIG. 1.

Gassen i beholderen 18 frembringer et overtryk i håndtaget 11, i røret 15 og i ventilmekanismen 10’s kammer 27. Dette tryk bevirker sammen med en fjeder 28, at ventilmekanismen 10’s reguleringsorgan 30 29 holder ventilmekanismen 10 lukket. For yderligere at forbedre ventilmekanismen 10’s tætningsfunktion er reguleringsorganet 29 forsynet med en tætningsring 30.The gas in the container 18 produces an overpressure in the handle 11, in the pipe 15 and in the chamber 27 of the valve mechanism 10. This pressure, together with a spring 28, causes the valve mechanism 10 29 of the valve mechanism 10 to keep the valve mechanism 10 closed. To further improve the sealing function of the valve mechanism 10, the control means 29 is provided with a sealing ring 30.

Claims

151358 When the rifle trigger 31 is affected, the following occurs. The portion of the trigger mechanism abutting the surface 24 provides resiliently so that the rear portion 8 of the training base 3 can move in the direction of the front portion 9 under the influence of the spring 13. A thrust 32 located on the rear portion 8 thereby a rod 33 on the regulator 29, thereby providing an instantaneous opening thereof, thereby discharging a sufficiently large amount of the pressurized gas from the chamber 27 to a chamber 34 in the valve mechanism 10 and further through a channel 35 in the front portion 9 to exert a force on the projectile 19 located in the barrel 23 of the exercise pipe 2, whereby the projectile 19 is fired from the rifle 1. The spring 14 returns the rear portion 8 so that the leading edge of the cam 32 takes up position C, and thus, the regulating means 29 of the valve mechanism 10 is returned to the closed position due to the gas pressure prevailing in the chamber 27 and due to the spring 28. Now the rifle 1 can be reloaded, whereby the cam The leading edge of 32 takes on the loading position A, and a new projectile 19 is born in the course 23, after which another firing can take place, etc. It should also be mentioned here that as the overpressure of the 20 gas in the chamber 27 decreases, the valve mechanism 10 at firing an ever-increasing gas dose due to the fact that the gas in the chamber 27 exerts an ever smaller force against the impact of the cam 32. This ratio helps to increase the number of good fires that can be achieved with each container 18.
