TECHNICAL FIELD The present invention relates to a bolt-operated rifle, and to a stop selector device for selectively stopping the movement of a stop screw, a trigger or a rib, or both.

The main parts of a conventional bolt-operated firearm consist of a barrel and a trigger comprising a barrel mounted in the receiver, the receiver fixed to the rear end of the barrel, the receiver mounted below the cylindrical bolt mounted coaxially with the barrel. . The cylindrical bolt is rotatable about its longitudinal axis from its fixed triggered position to an unfixed release and loading position, the bolt being actuable longitudinally within the receiver without the bolt being locked. have.

When the bolt is rotated from its fixed position to an unfixed position and moved to the rear side, the casing is pulled out of the chamber of the barrel and released. When the bolt is advanced from the rearmost position, new ammunition is inserted into the barrel of the barrel. When the bolt reaches its foremost position, it is rotated about its longitudinal axis, the bolt is fixed and the trigger is raised.

The bolt of the tail is combined with a spring-tight type of iron which is fixed with a stop screw in the cocked ready position. The stop screw is moved and the diaphragm is released by activating the trigger.

Various devices have been proposed for preventing movement of the septum, stop screw or trigger to prevent the septum from moving towards the ammunition, but none of the features and advantages of the present invention have been provided.

The present invention consists of a selector device capable of stopping the movement of a trigger or bolt handle or both. The device includes a rotary selector having a selector body portion and a selector handle protrusion in a fixed state, a trigger and stop screw stop coupled to the selector body portion, and a bolt-handled plunger movable by the selector protrusion, thereby rotating the selector. In the first position, the trigger and stop screw earth block the movement of the trigger; in the second position, the selector keeps the trigger and the stop screw in the blocking state; additional movement of the selector causes the bolt plunger to move the bolt handle. Allow it to stop This third position of the selector device is passive.

A feature of the stationary selector device is that the selector projection moves to the position of the request formed in the rib when the selector comes to the second position. In this position, the selector protrusion will prevent the rib from moving forward.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In FIGS. 1 and 2, the rifle 10 is arranged in the receiver 12 at the rear of the barrel 11, the receiver 12 fixed to the rear of the barrel, axially aligned with the barrel 11 and at the rear of the barrel. Mounted cylindrical bolt assembly 13, bolt handle 14 fixed to the rear end of the bolt assembly 13, bolt head sleeve 16, rib 17, receiver end 18 and butt 21 It includes. The rifle 10 also includes a trigger 22, a trigger 23, and a rotary stop selector device 26. This selector device 26 is mounted in the receiver and rotates about its vertical axis.

In FIG. 3, the trigger 22 rotates about the trigger rotational axis 28 and the trigger upper side 29 is adapted to be coupled to the stop screw request 31 of the stop screw 32. The stop screw 32 is arranged on the rotary shaft 33 and a spring 36 is interposed between the trigger 22 and the stop screw 32. Pulling the trigger 22 to rotate the trigger 22 clockwise about the rotary shaft 28, the upper side 29 of the trigger is released from the stop screw demand 31, the stop screw 32 is the rotary shaft 33 Loosen the septum 17 by rotating clockwise around the center. The rigger then advances under the force of a spring (not shown), smashing the detonator of ammunition (not shown) and firing it from the rifle.

In FIGS. 4-8, the selector device 26 is determined by a detent 37 inserted into one of the three stop requests 38, 39, 40 (FIGS. 4-7). It is shown that it is rotatably installed so that it can be stopped by rotating to three discontinuous positions. The selector device 26 includes a cylindrical body 43 for retracting the detent 37 at its lower position (FIG. 7) and two slot areas 44, 45 formed in the central portion of the body 43. Defines a first selector cam surface 46 and a second selector cam surface 47. The selector device 26 also includes a protruding piece 41. The slot area 44 is wider than the cam follower 54 so that the cam follower 54 can be inserted (FIG. 4). The slotted area 45 is narrower than the slotted area 44 so that the cam follower 54 cannot be inserted into the slotted area 45 at the position of FIG. 6, but instead the cylindrical surface 50 of the selector body 43. It is supposed to cross over. In FIG. 7, the cam follower 54 surrounded between the frame members 55 is wider than the slot area 45. As shown in FIG.

On the other hand, a cam follower 56 that is thinner than the cam follower 54 is inserted into the slot area 45 through the entire rotation of the selector 26.

The trigger control lever 51 is rotatable about the rotation shaft 53. The upper cam follower 54 and the lower cam follower 56 are mounted at one end of the lever 51, while the trigger stop piece 57 is placed at the other end. The lever 51 is moved away from the trigger 29 by the spring 59.

In FIG. 8, the rib 17 has a stop request 60 into which an axially extending projection 41 can be inserted when the selector device 26 is rotated to the positions shown in FIGS. 6 and 8. Has In this selector position, the stop plunger 52 is inserted into the bolt grip request 61 by the selector 26 to stop the movement of the bolt grip 14. When plunger 52 is released by selector 26, spring 64 causes plunger 52 to be retracted to free handle 14.

In summary, the selector device 26 engages and moves the trigger control lever 51, causing the trigger to stop its movement and, in turn, the stop screw to stop (see FIGS. 4-6). The selector device also restricts the movement of the rib 17 (FIGS. 2 and 8), and causes the stop plunger 52 to stop the movement of the bolt grip 14 (FIG. 8).

Stepwise, the selector device 26 is rotated to a manual or neutral position through the protruding piece 41 so that the detent 37 is formed on the stop demand 38 formed in the cylindrical body 43 having the cam faces 46 and 47. In this position, the trigger stop piece 57 of the lever 5l does not block the trigger 29 in this position (see FIG. 4). At these selector positions, fire is triggered. The selector device 26 is moved to the first stop position in order to limit the movement of the stop screw, where the detent 37 moves into the request 39 so that the cam surface 46 is a lever. The cam follower 54 of 51 is moved so that the stop piece 57 of the lever comes into contact with the upper side piece 29 of the trigger (see Fig. 5). In this position, the trigger upper piece 29 is prevented from rotating in the clockwise direction about the rotational axis 28 so that its operation is stopped (see FIG. 3). The trigger 22 is not rotated and the stop screw does not fall off so the rifle is not triggered. In addition, the lever 51 and its stop surface 57 may be designed to block the rotational movement of the stop screw (32).

Finally, the selector device 26 is moved to the second stop position, during which the cylindrical surface 50 moves the cam follower 54 such that the lever 51 is locked in its trigger-stop screw stop position. . When the protruding piece 41 causes the selector device 26 to be moved to its third position, the protruding piece 41 is in contact with the inclined surface 63 so that the stop plunger 52 moves into the right side 61 of the right side so that the handle ( Block the rotation of 14). During this movement the spring 64 is compressed. When the selector reaches this third position, the protruding piece 41 is in the stop request 60 of the rib 17 and restricts the forward movement of the rib 17 (see Figs. 6 and 8).

In operation, the slotted area 45, the cam surface 47 and the cam follower 56 operate to move the lever 51 to the manual or neutral position of FIG. 4, while the slotted area 44, the cam surface 46 ), The cylindrical surface 50 and the cam follower 54 operate to move the lever 51 to its stop position and to be fixed when the selector is in the first and second positions as mentioned above.

Figures 9-18, in particular Figures 16 and 18, show another embodiment of the present invention, in which selector 26a (such as selector 26) is installed in detent hole 71 in receiver 12. It has been shown that it is rotatably installed so as to be rotated and fixed to three discontinuous positions determined by the detents 70. The detent spring 72 causes the detent 70 to be inserted into the requests 73, 74, 75 of the selector 26a. The selector 26a includes a protruding piece 77, and the cylindrical body portion 78 includes an angle 79. Each portion 79 is provided with a request 81 that constitutes a structure that is coupled to and separated from the trigger as will be described in detail later. The trigger 82, which is rotatable about the rotating shaft 83, includes a finger rest piece 84, a stop screw engaging trigger upper side 86, and a trigger extension portion 87 having an extension protrusion 88. In addition, in FIG. 16 and FIG. 18, the trigger side pieces 89 and 91, the stop screw 92, the stop screw spring 93, the stop screw pin 94, the cover plate 95, and the rifle scale 96 Is shown.

Again in FIGS. 12, 13 and 14, when the selector 26a is in the position A (FIGS. 12 and 14), the angles 79 of the selector 26a are extended by the extension protrusions 88. The insertion position causes the trigger 82 to rotate in a clockwise direction and the stop screw 92 is released to cause the rifle to be triggered (FIG. 12). When the selector projection piece 77 has returned from the A position to a position where the rectangular projection 88 can no longer be inserted into the request 81 (B position in FIG. 14). A portion of the septum 79 moves adjacent to the protrusion 88 (with minimal spacing) so that the trigger 82 does not rotate in this position. In this position, the trigger 82 does not rotate clockwise to release the stop screw 92 to trigger the rifle.

In FIG. 17, the selector is further retracted to show that it lies within the cradle's request 60. The movement of the selector 26a to the C position of FIG. 14 for fixing the bolt grip 14 is the same as the operation of the selector 26 already mentioned.
