Description

OSSCRIPTiOb (.00D13 The invention relates to a repeating rifle with a housing, a barrel that in detachably -connected with the housing, and a breach mocha π a cm that is guided in the housing and can be locked with the barrel. In any case, the breech mechanism is a body guided in the longitudinal direction in the housing, wherein various locking systems come into question; those with rotation of the breech mechanism and others. In the case of the former, the breech mechanism is locked either by displacing and rotating the bolt handle or by displacing the bolt handle and a sliding-block guide. The present invention can be applied for both modes of operation:. In certain cases, the invention is also suitable for breach mechanisms without rotation. i 0002 j DE 103 32 932 B3 and DE 196 02 <130 AX may be mentioned as examples of weapons with locking by means of rotation of trie breech mechanism. In the case of the former, the bolt handle acts directly on the breech mechanism, in the case of the second, on a breach carrier with a Spital sliding-block guide. : 0003] A hunting rifle with replaceable barrel is known from the patent specification AT <1:00 269, into which various barrels: and correspondingly various breech mechanisms can be inserted. For replacement however, the weapon amist be substantially disassembled, which is labour-intensive end made more difficult by the fastening of the barrel.

[0004] DE 28 34 332 <32 relaxes to an automatic weapon with a replaceable barrel. In this case, the gas extraction at the barrel is configured such that, for a replacement, the barrel is first rotated and subsequently axially pulled out. The breocrr mechanism is provided in the housing.

[Ö0051 DE EG 2005 036 251. El :: e .lat e $ to a ga$-pressure-charged automatic rifle with a replaceable barrai. Â locking bushing is securely attached on the barrel, which secures the breech head on the locking nipples thereof using locking nipples that face radially inwards, [:0006] US 3,849,025 hi describes a mechanise; of a replaceable barrel, using which the breech head may also be unchanged.

[:0007} It is an object of the invention to configure a repeating rifle in such a manner that the exchange of barrel and breech nee ha: near; is possible with a minimum of handles and preferably even simultaneously, and a space-saving and reliable connection of breech head and breech body becomes possible. jjOOOS] This object is achieved with a repeating rifle according to the attached Claim .1., The breech mechanism of the repeating rifle according to the invention is divided into a breech body that can be locked with the barrel using corresponding looking parts and a breech body that, is guided in the housing. The breech head and breech body are connected to -on®, another in such a manner that they can be separated from one another when the breech body is in the locked position, so that the barrel can be pulled forward out of the housing simultaneously with the breech head locked therein, in this case, a rear part of the breech head plugs in a coaxial hole of the breech head and is held there by coupling parts (particularly balls) engaging into â: peripheral groove. When the breech head is pulled out, these must he pushed radially outwards, which is only possible in a certain position (position and, if appropriate, angular position] of the breech body. Namely, only in the locked position do recesses in the guide of the hr eeon Cody a 1 lew tin s , [0069] Depending on the design of the breech mechanism* the breech boo y cam be guided either in the housing or in a* breech carrier. In the former case, the breech mechanism is locked by displacing and rotating the bolt handle, and the recesses are arranged in the housing, In the second case, locking: is carried out by displacing the bolt handle and a sliding-block guide in the breech carrier, wherein the recesses are installed in the: breech carrier. In the second ease, one speaks of a straight-pull breech mechanism. In the case of such a breech mechanism, the breech body is guided linearly in the housing in the longitudinal direction in a particularly good and therefore preferred embodiment. Because the control bolt connue red securely to the breech body is guided both on the motron link in the breech carrier and in the housing, and inevitable guiding of the breech head through to full locking is achieved in a simple manner, Ά fixture on the rear part of the breech foody, which has a groove with a particular position and length running in the longitudinal direction into which a cog of the breech body engages, and which forms a stop for a head at the rear end of the firing pin, ensures that s shot can only be fired when the breech mechanism is fully looked, [001:01 The separable connection of the barrel to the housing can be produced in various ways In the context of the invention. In a preferred design, the locking bushing fits into a cylindrical hole of the housing and is fixed by means of a rotatable eccentric. The eccentric interacts with a mating surface with a generator that is skew to the running amis. Thus, the barrel can be detached from the housing using one handle and pulled out of the housing together with the breech head using a further handle, [0Q1IJ In a development of the invention, a gear ratio may be applied for displacing the breech carrier instead of a hammer handle.

[0013] In Fig. X, a repeating rifle with a housing 1, a barrel 2 and a breech mechanism 3 is shown in a longitudinal section view, The barrel 2 is securely connected to a locking bushing 4 by means of a thread 5 or in some other way, This looming bushing surrounds the rear end of the barrel 2 containing a cartridge chamber 9 and projects to the rear beyond that. The locking bushing 4 sits in a cylindrical dole 3, of considerable length, of the housing X and is fixed therein by means of an eccentric 6 engaging into the looking hushing 4 from outside, which eccentric can be rotated fey means of a hand-operated lever 7. The axis of the eccentric 6 is skew to the running axis and the locking bushing 4 has a mating surface 33 with a generator which is skew to the running axis and accommodates the eccentric ë, In the position shown, the barrel 2 is securely connected to the housing I. Rotated through a right angle, the eccentric 6 releases the barrel 2, so that it can be pulled forward out of the housing 1, [ÖÖ14] In Figs 2 and 3, the important parts are illustra red enlarged in sectional views and can be seen better as a result. The locking bushing 4 forms first locking parts 10 on the inside at its part located, behind the barrel 1, which here are a plurality of rows of si i urn: 1 y rising segments (termed nipples; distributed over the periphery, interrupted by longitudinally directed passages 11 (intermediate spaces) for second locking parte 30 on the breech mechanism 3, The housing has a longitudinal groove 12 and a transverse groove 13 on its upper inner side. Furthermore, a cocking slide 1<I can be displaced in the longitudinal direction in the hous1ng. It could be securely connected to the breech mechanism 3, In the design shown, it carries a pinion 13, which engages at the top with a first toothed rack 16 fastened on a part of the breech mechanism 3 and at the bottom with a hocsing···fixed second toothed, rack 38, which is only indicated. Therefore, a step-up gear ratio is created or the path of the cooking slide 14 is shortened. 100‘1.5} The breech mechanism 3 consists of a breech carrier 17, a breech head 18, a breech body 19, a fixture 21 and of a cover 24, Here, the breech carrier 17 is securely connected to the first teethed rack in and is guided on the housing 1 in the longitudinal direction by means of guide rails iö (Fig.* 3), At it® front end, the breech. head 18 forms the second locking parts 30, which fit into the intermediate spaces 11 between the first locking parts 10 of the locking bushing: 1. S rear part 31 of the breech bead 18 is connected to she breech, body 10 in a manner to be described below., The breech body 13 is a graduated cylinder and guided in the breech carrier· 17 in a dispi aceable and rotatable manner. To this end, a control bolt 20 protrudes radially outwards out of the same into a motion link 31 of the breech carrier 1? and into· the longitudinal groove 12 or into the transverse groove 13 of the boosing 1. In Fig, 3, the control bolt 20 is illustrated in the longitudinal groove 12:, and as 20* in the transverse groove 13, The motion link 41 of the breech Carrier 17 consista of a spiral part il' and of a short longitudinally directed part 41” (Fig, 5} adjoin!eg at the rear. :(0016] The fixture 21 is guided on a rear part 27 of smaller diameter of the breech body 13 and connected such that it is rotationaily-f i xed, but displaceable in the longitudinal direction, to the breech carrier 17. To this end, it has a longitudinal groove 23 of certain position and length, into which a cog 22 fastened on the breech carrier 17 engages, At the rear, the fixture 21 forms a stop 26, which ensures that the firing pin 2 5 can only be fired if the breech mechanism 3 is locked, [0017] in Figs 4 and 5, the breech mechanism 3 can ba seen without a housing 1;. and above all the connect!on between the breech head ! 8 and the breech body 19 can be seen. To transmit torque between the breech body 13 and the breech fiend IS, both parts have longitudinally directed planar coupling surfaces 32 which are only indicated, They allow a displacement of the two parts in the axial direction. The rear part 31 of the breech head 18 plugs in a central bore 29 of the breech body 19 and has a peripheral groove 34 close to its end1, The breech body 19 has a number of (preferably three ) radial holes 36 (Fig, 5) distributed over the periphery* There and the peripheral groove 34 together offer just enough room In each case for one coupling: body 35, ideally a ball, in each case. Because the halls 33 cannot escape outwards, they fort! a positive-fitting connection, acting in a detachable manner in the longitudinal direction, between the breech head 18 and the breech body 19, [0013] To detach the connection, the breech carrier has reccssea 42 on its inner cylindrical guide surface 28, which, in a certain position of the breech body 13, adjoin the radial holes 36 and elongate the same outwards, so that the bails 35 can be pushed into the same when the breech head 18 is pulled out of the breech body 13. This position corresponds to the locked breech mechanism both in the longitudinal direction and in terms of the torsion angle;, The two breech parts can only be separated from one another in this position, [0019; The mode of operation of the device according to the invention is described in the following. Fig, 4 and Fig, 5, in which the breech mechanism is open and depicted in its rearmost position, are taken as a basis. This position was reached by pulling back tbs breech carrier 17, Therefore, the rear stop surface 4 5 of the breech carrier 17 bears against the stop surface 4 6 of the fixture 21, and the stop 26 of the fixture 21 has pulled back the firing pin 25, The control boit 20 is guided in the longitudinal groove 12 (Fig, 2} of the housing 1 and penetrates the spiral first part 4Tf of the motion link 41 of the oreach carrier 17 in its foremost section. The breech head 18 and breech body 19 are connected to one another by means of the balls 35, because the bails 35 cannot be pushed outwards; the recesses 42 provided therefor in the breech carrier 17 are much further back in this position.

[0020] : Figs 6 and 7 show the breech mechaniso. 3 in the locked position^ it reaches this position because the breech carrier 17 is poshed forwards here by acting on the toothed rack it, lineariy initially (along the guide rails 40 in the housing 1)- In this case# the control bolt 20 Is initially godded in the longitudinal groove 12 (flu« 2;, so that the breach head 18 and the breech body 19 also move linearly as far as their foremost posit ion, in which the breech head 18 dips into the locking bushing 4 > In this intermediate position, the control bolt is still right at the front in the first part 41 ' of the motion link 41, because it was guided as far as that in the longitudinal groove 12 in the housing. (0021] As soon as the control bolt 20 has reached the transverse groove 13 (rig,. 3), the first part 4 Id of the motion link 41 rotates the breech head 18 and the breech body 19 as the breech carrier 17 is pushed further forwards. Thus, the breech mechanism is brought into the locked position shown in Fig, 8. (0022; In this looked position, the recesses 42 of the breech carrier 17 are brought to match the radiai holes 36, in which the balls 33 are located. This causes the balls to be pushed out Into the recesses 4 2 and the breech head 18 can be pulled cut of the breech body 18, If the barrel assembly consisting of the barrel £ and the locking bushing 4 is pulled forward cut of the housing after the detachment of its connection to the housing 1 (toy rotating the eccentric 6), then the breech head 18 locked to the locking bushing 4 is pulled out with the same. This is 1 idustraced in Fig:, 9 and indicated with the arrow 48. In this manner, various barrels (of various calibres) can be kept ready with the matching breech heads and inserted into the rifle together , :(0023] The unlocking and opening of the breech mechanism is also described on the basis of Fig. 8,- although in this case, the movements listed for fig. 8 take place in the reve read sequence, lx the breech carrier 17 is pushed backwards, the control bolt 20 is initially rotated irons the first part 41' of the groove il and the breech mechanistt is thus unlocked, That is the position shewn in fig, 8. The breech carrier 17' then pulls the breech mechanist's (IB, 1-7) linearly backwards, because the control bolt 20 is guided in the longitudinal groove 12 (Fig. 2} . Likewise, it pushes the fixture 21 backwards by contacting the stop surfaces 4c, 4€ and the stop 26 thereof pulls the fifing pih 25 back. Because of the displacement of the breech carrier 17 with the recesses 42 thereof in relation to the breech body 19, the balls 35 again form a positive-hitting: connection, (0024 j Only one exemplary embodiment of the invention has been described, from which it is possible to deviate in. many instances. What is important is separating the breech mechanism into two parts, of which one can be removed from the housing, locked with the: barrel. In this case, locking does not have to taka place by rotating a breech part, and if the locking takes place by twisting, this rotat ton does not have to be forced by a motion link in the breech carrier, it can likewise take place directly by means of a bel t handle ,
