Bayonet-mounted quick-release piece for gun muffler

The invention relates to a bayonet-mounted quick-attaching piece 5 for a muffler for a weapon, which extends from the muzzle-shaped body part of the body part, the inner part of the barrel of which is adjustable, to the rear part of the body of the weapon barrel. a section for performing a quick-release body and a barrel stroke such as a grain silent bayonet attachment.

Bayonet attachment has long been a way of attaching a muffler to a weapon. The bayonet-15 is fastened in such a way that the muffler can be attached directly or by means of a special quick-release piece as an extension of the barrel of the weapon, whereby the cut in the muffler or quick-release piece locks the muffler or quick-release piece in the barrel 20. The cut can be, for example, a part removed from the area of the quarter circle, i.e. an open part in the cylindrical wall mass of the quick-fastening piece.

The bayonet-mounted mounting piece previously known in the art is one in which the inside of the mounting piece 25 is a cylindrical piece which can be damped and screwed with a screwing tool to turn backwards towards the barrel of the weapon. In that solution, the barrel of the gun and the barrel of the cylindrical body have a large spring. From the point of view of the use of a weapon, this structure is naturally very dangerous. Silia sometimes occurs in situations where the weapon, which is assumed to be empty for cartridges, contains a cartridge which, due to careless handling of the weapon, fires excessively and injures handlers, especially when the bullet passes 35. there is an obstacle in the muffler, i.e. in this case 2 91918, the muffler. In addition, this construction requires the production of a thread inside the fastening piece, which is done with absolute precision. The Silia thread naturally guides the cylindrical kappa-5 threaded into the thread. Due to the above-mentioned fact and the presence of a cylindrical convex body and a silent spring of the weapon barrel, it is clear that this solution cannot ensure with sufficient accuracy and yet a simple construction that the barrel of the weapon is aligned with the muffler.

Conventional mufflers that do not use a bayonet mount have solutions in which the muffler or mount is attached to threads made in the barrel of the weapon. In addition, there are 15 other attachment methods that have in common that they always require some degree of change in the barrel structure of the weapon. Usually, the necessary changes are related to the machining of the barrel or, for example, the relocation of the grain to a different location. It is clear that any excess modification of the weapon causes extra costs and affects the outer surface of the weapon, which manifests itself, for example, as a damage to the surface treatment layer of the barrel of the weapon. The solutions currently in use are always weapon-specific, which limits the use of the muffler.

The object of the present invention is to provide a new type of quick-release piece which overcomes the problems associated with the known solutions.

This object is achieved by a long-distance fastening piece according to the invention, characterized in that the quick-fastening piece 30 further With the target piece 35 being able to be tightened against the silicon punch of the weapon by the appeal of the body-shrinking silencers 3,91918.

The quick-release piece according to the invention achieves important advantages. The weapon does not need to be made of co-5 cuts and the quick-release piece is easy to manufacture from a manufacturing point of view. By means of the alignment piece and the tightening piece which is threaded from the outside and the previous alignment piece directly against the barrel, the alignment of the barrel of the weapon with respect to the muffler can be obtained very precisely just and still in such a way that tightening can be carried out safely without special means.

The invention will now be described in more detail with reference to the accompanying drawings, in which Fig. 1 shows a side view of a quick-release piece partly diagrammatically, partly in cross-section, Fig. 2 shows a bayonet-type fastening of a gun barrel the body of the arrow in Figure 3 Ά direction of view, Figure 5 shows the clamping pieces 25 Figure 6 shows a functional instrument the metallikuu- glycol, Figure 7 shows a snap fit, the face surface and the alignment body portion vaiiin adaptive VAII disc 30 Figure 8 shows equipped lukitusvalineelia koh distuskappaletta axially , Fig. 9 shows a cross-section of the alignment piece, Fig. 10 shows the quick-attachment-35 piece of Fig. 1 in connection with a thin cylindrical barrel.

Fig. 3 shows the run-part 1 of the quick-fastening piece. A fastening means 2 for the muffler is formed on the left edge of the body part 1. The fastening line 2 can be, for example, a thread into which the muffler thread 5 is retracted. In addition, the body part 1 encloses a cylindrical wall 3 with a circular cross-section. In order to enable a Bajo-net type attachment to the wall 3 of the body part 1, a cut 4 is formed, i.e. in use a part of the perimeter of the wall 3 is removed so that the gun barrel 5a shown in Fig. 2 and the grain 6 in the gun barrel 5a can be impregnated. Inner and locked in the direction of arrow B, parallel to the rotational motion of the leikkauk-4, which according to Figure 3 comprises the edge of the rear edge of the front 7 and 8, which vaiiselle area silicon grains 15, the pussa 6 is placed. Referring to Fig. 2, the barrel 5a of the gun rotates from position C to position D. Referring to Fig. 3, the body part 1 covers the end surface 9 of the myOs.

In Fig. 1, the quick-fastening piece is shown mainly in such a way that the area below the line E is shown schematically and the area below the line E is shown in cross section. However, the barrel 5 of the weapon is shown schematically on both sides of line E, and in addition, on the left side of Fig. 1, the attachment of the muffler 10 is shown partly on both sides of line E, both schematically and in cross section. According to the basic idea of the invention and Fig. 1, the quick-fastening piece 11 can be directly tightened against the barrel of the weapon barrel 17 by means of the silencing of the spacers 14-16 of the body end surface 9. The barrel mouth 17 of the weapon T31 is against the alignment piece 11 35 and in addition the barrel 5 of the weapon

5 91918 to the surface 18 on the longer path if the barrel is cylindrical and thick, and correspondingly shorter distance on the inner surface 18 of the wall 3 of the body part 1, the barrel 5 is conical as shown in Fig. 1. In the case of Fig. 1, however, the barrel 5 is so thin, i.e. small in diameter, that it does not rest directly on the inner surface 18 of the wall 3, but quietly. The clamping piece 13 pushes the front surface extending silicon pieces 14-16 to the front, which push the alignment piece 11 against the barrel mouth 17.

The alignment piece 11 is adapted to slide laterally on the inner surface 18 of the wall 3 of the quick-attachment piece. The structure of the alignment piece 11 and the inner surface 18 of the wall 3 of the body of the quick-fastening piece can be easily saturated when the alignment piece without threads or other similar structures can be tightened against the barrel 17. In contrast, the threads occur in the external tightening piece 13.

In a preferred embodiment of the invention, the inner surface 20 of the alignment piece 11 to be tightened against the barrel 17 engages the conical portion 19. In particular, if the barrel 5 of the weapon has a front oblique 20 according to Fig. 1, the tail conical alignment piece 11 aligns with the barrel 17.

According to Figures 1, 8 and 9, in a preferred embodiment of the invention, the alignment piece 11 has a cylindrical edge portion 21 extending parallel to the wall 3 of the body part 1. The cylindrical edge portion 21 may either replace the conical portion 19 or, according to Figures 1, 8 and 9, may be such that the cylindrical edge portion 21 is formed as an extension of the conical portion 19 in the preferred embodiment of the invention. The conical portion 19 or the cylindrical edge portion 21 or the former together make it possible that the inner surface 18 of the wall 3 of the quick-fastening body does not need to be machined for a long time to correspond to the committee of the barrel ul-35. On the other hand, it is sufficient that the short and considerably more easily machinable alignment piece is machined in such a way that the mouth 17 of the barrel 5 partially enters the interior of the alignment piece 11, i.e. the conical portion 19, the cylindrical edge portion 21 or both. If necessary, the cylindrical edge portion may be longer than shown in the figures, especially when there is no conical portion 19.

The alignment of the barrel mouth 17 of the weapon is particularly precise when, as mentioned above, the cylindrical edge portion 21 is formed as an extension of the conical portion 19 of the alignment piece 11, because the barrel mouth 17 of the tailpiece 17 rests on both the conical portion 19 of the alignment body 11 and its extension. .

In a preferred embodiment of the invention, the alignment piece 19 extends at most to the level of the leading edge 8 of the section 4 of the body part 1. In the case of use according to Figures 1, 8 and 9, the aforementioned structure means that the cylindrical edge part 21 does not have a wall 3 on which the section 4 is formed in the Silia part 20. The aforementioned structure allows the alignment piece 11 not to prevent the barrel 5 and the grain 6 therefrom from advancing to the leading edge 8 of the cut.

In Fig. 9, the alignment piece is shown in cross-section. The outer sides 22 and 23 of the alignment piece are those points where the alignment piece 11 is in contact with the inner surface 18 of the wall 3 of the body 1 of the longitudinal fastening body, more specifically that part of the inner surface which is closed and into which the section 4 of the bayonet mount 30 does not extend. In Figure 3, this closed area is approximately along the line A.

It can be seen from Figs. 8 and 9 that the cylindrical edge portion 21 extending the conical portion 19 is less than the position indicated by reference numeral 24, i.e., 35 from the section 4 in the wall 3 of the body 1 of the fastener 7191918 and thus the above in such a way that the alignment piece 11 does not prevent the barrel 5 and the grain 6 of the weapon from advancing all the way to the leading edge 8 of the cut 4. The center of the alignment-5 body is, of course, an opening 25 through which the projectile can pass.

Referring to Figures 1, 3 and 4 and 6, in a preferred embodiment of the invention, the end face 9 of the body part 1 engages openings 26 to 28 into which the silicon pieces 14 to 16 are fitted. With this solution, the pushing force obtained from the rotation of the clamping piece 13 can easily be silenced through the spacers 14-16 in the openings 26-28 in the end face 9 to further fill the alignment piece 11 against the barrel 17. In a preferred embodiment of the invention 15 silencers 14-16 and openings respectively 28 are at least three pieces and are substantially symmetrically arranged in the region of the end face 9. With this solution, the advantage is achieved that the alignment piece 11 is made to advance evenly in the axial direction. The arrangement of the silia alignment piece 11 inside the walls 3 is quite tight. According to Figures 1 and 6, the spacers 14 to 16 are preferably balls, such as metal balls 14 to 16. Alternatively, pins may be present instead of balls 14 to 16. Next, the structure of the quick-release piece 25 will be described, the most important removable parts of which are shown in Figs. 3 and 5 to 8. Assembled, the quick-fastener piece is shown in Fig. 1. The basic fastener piece structure is formed by the body part 1 in Fig. 3. 28 to 30 is placed in the direction of arrow A vaiikappaleet a metal likuulat 14 to 16 Figure 4 shows the body part 1 is shown in the direction of arrow 3 of Fig Ά viewed in the direction of the silencer 10, namely the direction in which the openings symmetrically located evenly spaced across the front seating surface 9 26-28 are placed ku in Figure 35 6 in the preferred embodiment of the invention. The spacers 14 to 16, i.e. the balls, are arranged on the end face 9 so that the weight of the silicone pieces 14 to 16 on the barrel 5 of the gun can be limited. This structure is very easy to implement in that the arrangement of the openings 26 to 28 is effected in such a way that the selection pieces 14 to 16, i.e. the balls, to be placed in the openings 26 to 28 appear at the end of the wall of the body. In Fig. 4, a circular dashed line 18 shows the inner surface 18 of the wall 3 of the body part 1. Fig. 4 shows a fastening means formed by the fastening of the muffler 10, i.e. a thread 2 and a thread 12 located in a wide rain and closer to the end face 9. 13 can be rotated by means of its own thread 29 15. Next, in the grooved groove 30 of the threads 2 and 12 shown in Fig. 3, a locking ring 31 is placed as a shaft lock, which prevents the tightening piece 13 and the balls 14-16 from coming loose. In the next step, the alignment piece 11, which in Figures 1, 8 and 9 covers the conical portion 19, can be placed in the space delimited by the closed area and the end surface 9 of the inner surface 18 of the body part 1, whereby the end 32 of the alignment piece 11 is approximately attached to the end surface 9. In the preferred invention In an embodiment, the quick-fastening piece comprises locking means for locking the alignment piece 11 to the body part 1 so as to prevent the alignment piece 11 from coming loose, but still allowing axial movement of the alignment piece 11. The locking means may advantageously consist of an opening 34 formed in the wall 3, a recess 35 in the alignment body 30 and for example a cotter 36 such as a cotter pin or the like fitted to the recess 35 through the aperture 34. The size of the aperture 34 is larger than the pivot pin 36 it is possible. This structure is an easy way to ensure that the alignment piece 11 pddse does not come off. The pin 36 also appears in Figure 8, where it is shown fitted directly into the recess 35 in the alignment piece 11. In a preferred embodiment of the invention, before the alignment of the alignment piece 11, a baffle plate 37 can be arranged between the end face 9 and the alignment piece 11, which can be, for example, a disc spring or another baffle plate as shown in Fig. 7.

The quick-mount cap 10 assembled as shown above is as shown in Fig. 1. The barrel 5 of the weapon can be fitted inside the wall 3 of the body part 1 for as long as possible. The barrel 5 of the TSllG weapon rests at least on the weapon-side end 40 of the body part 1 on the inner surface 18 of the wall 3 of the body part 1. The inner diameter y of the wall 3 of the quick-attaching barrel 5 is dimensioned from the barrel of the weapon barrel from the area x from the side of the gun side 40. For a thick cylindrical barrel, the inner diameter y of the wall is dimensioned directly on the basis of the diameter of the barrel. Next, the alignment and alignment according to the basic idea of the invention can be performed by turning the clamping piece 13 along the thread 12 closer to the end face 9, whereby the baffles 14-16, i.e. the balls, meet the alignment piece 25 directly against the barrel barrel 17. The alignment piece 11 aligns that is, center and align the barrel 5 of the weapon correctly with respect to the quick-release piece and the muffler 10.

Fig. 10 shows a quick-mounting piece 30 corresponding to Fig. 1, but arranged around a cylindrical barrel 5a. If the barrel 5a is thin, then, according to Fig. 10, in a preferred embodiment of the invention, the quick-fitting piece mates a barrel 5 of the barrel 5a and the inner surface 18 of the quick-fitting piece, which ensures that the barrel 5a and the quick-fitting 91 91 8 ------ 'Γ “10 workpieces are tightly supported. In use, the flap body 41 is an annular constriction from which a part of its circumference has been removed, so that the barrel 5a of the weapon and the grain 6 therein can be filled into the flap body. The shrink sleeve 5le 41 is preferably realized in such a way that its axial length is equal to or less than the quiet distance x of the edge 7 of the cut 4 in the backrest 3 of the quick-release piece and the gun-side side 77 of the quick-release piece. The shrink ring of the tail does not form an outer 10 nadl harm. In Fig. 10, the length of the contraction piece 41 is dimensioned to be equal to the distance x. Figures 10 and 2 show a similar situation, i.e. a situation in which the quick-fastening piece is arranged around a cylindrical thin barrel, i.e. a small-diameter barrel 5a, whereby there is a need for a myOs contraction piece 41.

In contrast to Figure 1, Figure 10 shows the myOs weapon grain 6 (dashed line), with Figure 10 showing well the principle of myOs bayonet attachment, where the grain 6 (or grain leg) rests on the front edge 8 and rear edge of the body wall section 3 7 vaiil-le.

Section 4, i.e. the open point in the wall mass 3, is best seen in Figure 3. In Figures 1 and 10, section 4 appears in the area of Silia bounded by lines 8, 18 and E. Section * 25 4 may be, for example, a quarter of the circumference of the wall 3. .

Although the invention has been described above with reference to the examples according to the accompanying drawings, it is clear that the invention is not limited thereto, but can be modified in many ways within the scope of the inventive idea set forth in the appended claims.
