Description

Detailed Description of the Invention

Field of Invention

The present invention relates to a bullet feeding mechanism used for a caseless type gas gun or an air gun in which a bullet or BB bullet is fed by a bullet feeding nozzle that moves back and forth in conjunction with a trigger, and then the bullet is fired.

A caseless gas gun or air gun that fires bullets and BB bullets using a bullet feed nozzle that moves back and forth in conjunction with a conventional trigger, and then fires the bullets, can be fired continuously, and its accuracy is low because there are few moving parts. Many are made because it consumes less gas. However, for bolts, bolt carriers, or slides that have the appearance of a bullet feed mechanism that moves back and forth, these bolts, bolt carriers, or slides have only been shaped to hide the engine. Most of them did not move back and forth (References 1 and 2).

Also, even if the bolt, bolt carrier, slide, etc. move back and forth, the engine part that has a different shape from the gun with a bullet feed mechanism that actually moves back and forth such as the bolt, bolt carrier, slide, etc. is visible. It had a bad appearance because it was covered with a cover to hide the engine parts with different shapes.

Further, even with a gas gun or an air gun that is fed by a bullet feeding mechanism such as a bolt, a bolt carrier, or a slide that moves back and forth, it has not been possible to feed or load from the bullet feeding mechanism (Reference 3). .

Problems to be solved by the invention

Even in caseless type gas guns or air guns, where bullets and BB bullets are fired by a bullet feed nozzle that moves back and forth in conjunction with the trigger and then fired, the bolts, bolt carriers, slides, etc. look nice rather than decorative Can be moved back and forth without dropping, and further, feeding and loading from the ejection port (rejecting port) opened by moving the bolt, bolt carrier or slide back and forth, loading and unloading the magazine, etc. It is a technical object to provide a bullet feeding mechanism that enables the above.

Means for solving the problem

It has bolts, bolt carriers, slides, and other members that are fixed in position and have no bullet feeding function, but they are not linked to bolts, bolt carriers, slides, etc. In the bullet feed mechanism used for the caseless type gas gun or air gun that feeds the bullets and BB bullets by the bullet feed nozzle that moves back and forth in conjunction, and then fires the bullets, members such as bolts, bolt carriers, slides, etc. When moving to the bolt action position, by moving the bolt, bolt carrier, slide or other member to the bolt action position, the bullet feed nozzle that feeds the bullet by moving back and forth in conjunction with the trigger. The interlocking is released and the bullet feed nozzle is moved to the bolt action position.

Hereinafter, an embodiment of a gas gun feed mechanism embodying the present invention will be described with reference to FIGS.

FIGS. 1 and 2 are a side view and a cutaway perspective view of a main part showing a state in which the entire engine part of the gas gun according to the first embodiment of the present invention is ready for firing. In the figure, 1 is a receiver, 2 is a bolt, 3 is a trigger (trigger), 4 is a bullet feed nozzle, 5 is a discharge valve, 6 is a rod, 7 is a magazine body (gas tank), 8 is a gas tank lid, and 9 is a hammer. (Shock iron) 10 is a hammer hand, 11 is a rod guide, 12 is an operating handle, 14 is a gas inlet, 15 is a chamber, 16 is an inner barrel (barrel), 17 is a bullet, 18 is an impact plate, 19 is a tank Seal, 20 is a magazine spring, 21 is a magazine catch (catch), 22 is a guide base, 23 is a trigger flexible base, 24 is a cam, 25 is a locking lug, 26 is a disconnect latch, and 27 is an outer barrel. .

Explaining these operations, the trigger 3 is interlocked with the respective members in the order of the hammer hand 10, the hammer 9, and the impact plate 18 in order of opening the valve 5, and is connected to the rod 6 connected by the trigger flexible base 23. It is connected. The rod 6 is guided by a rod guide 11 and is arranged behind the bullet feed nozzle 4. FIG. 3 is a cutaway perspective view of the main part viewed from the same position as in FIG. 2 and shows a state in which the trigger 3 is pulled for firing. When the trigger 3 is pulled, the trigger 3 rotates around the shaft 3b to move the rod 6 forward. The rod 6 presses the rear end 4 a of the bullet feed nozzle 4, the tip 4 c holds the grain bullet 17, and feeds the grain bullet 17 into the chamber 15.

Referring to FIG. 1 again, the trigger 3 moves the rod 6 forward and simultaneously moves the hammer hand 10 forward. Since the hammer hand 10 presses the end 9a of the hammer 9, the hammer 9 rotates around the shaft 9b in the clockwise direction in FIG. Since the hammer hand 10 is close to a linear motion, the end 9a of the hammer 9 and the hammer hand 10 are uncoupled immediately before the trigger 3 is pulled, and the hammer 9 is biased by a spring, so that the hammer 9 is counterclockwise around the shaft 9a. Rotate around. The impact plate 18 is pressed by the momentum of the hammer 9, and the impact plate 18 further presses the valve rear end 5 a of the discharge valve 5. The valve 5 pressed against the rear end 5 a moves forward and opens the valve 5 from the gas chamber 7 to the bullet feed nozzle 4, so that the gas reaches the gas passage 4 b of the bullet feed nozzle 4 and the bullet feed nozzle 4. The particle bullet 17 of the tip part 4c is fired. In order to open the valve 5, the length and thickness of each member are adjusted so that the particle bullet 17 jumps out vigorously by the gas pressure after the particle bullet 17 is fed into the rubber chamber 15 by the bullet feed nozzle 4.

4 and 5 are perspective views in which the main part viewed from the same position as in FIG. 2 is cut away. When an operating handle (not shown) is operated to move backward, the operating handle contacts the bolt 2 and moves backward and forward with a direction in which the operating handle and the bolt 2 are moved forward and backward by projections (not shown) provided to each other. , The bolt 2 is rotated counterclockwise. Since the rear end portion 4a of the bullet feed nozzle 4 is provided off the axis of rotation of the bolt 2, the engagement between the rod 6 and the rear end portion 4a of the bullet feed nozzle 4 is achieved by rotating the bolt 2. The state is released and the state shifts to the state shown in FIGS.

When the operating handle is further moved backward from the state of FIG. 4, the engagement between the rod 6 and the rear end 4 a of the bullet feed nozzle 4 is released, so that the bolt 2 is obstructed by the rod 6. Accordingly, the operating handle can be moved rearward without moving the bolt 2 to the bolt action position shown in FIG.

In the above description, the bolt 2 is rotated counterclockwise when viewed from the rear with the direction of movement of the bolt 2 in the front-rear direction as an axis, but the same effect can be obtained even if the bolt 2 is rotated counterclockwise.

Therefore, this mechanism can move the bolt 2 to the bolt action position without deteriorating the appearance.

Further, in the state shown in FIG. 5, the bolt 2 is completely moved to the bolt action position, and there is no trouble other than the bolt 2, so that the bullet 2 is loaded and loaded from the ejection port opened by the movement of the bolt 2. The magazine can be attached and detached.

6-9 is the perspective view which expanded and cut off the principal part of Example 2 of this invention. In the first embodiment, the bullet feed nozzle 4 is directly hit by the rod 6, whereas in the second embodiment, the upper portion 3 c of the trigger 3 directly presses the bullet feed nozzle 4. Since other configurations are the same as those described in the first embodiment, detailed description thereof is omitted, and the same reference numerals as those in the first embodiment are used.

In order to open the valve 5, the trigger 3 is interlocked with the respective members in the order of the hammer hand 10, the hammer 9, and the impact plate 18, and the trigger end 3 c is disposed behind the rear end 4 a of the bullet feed nozzle 4. Is done. FIG. 7 is a cutaway perspective view of the main part viewed from the same position as FIG. 6 and shows a state in which the trigger 3 is pulled for firing. When the trigger 3 is pulled, the trigger 3 rotates about the shaft 3b, the trigger end 3c presses the rear end 4a of the bullet feed nozzle 4, the bullet feed nozzle tip 4c holds the grain bullet 17, and the grain bullet 17 Into the chamber 15.

By pulling the trigger 3, the hammer hand 10 (not shown) is moved forward simultaneously with the operation of feeding the particle bullet 17 into the chamber 15. Since the hammer hand 10 presses the end 9a of the hammer 9 (not shown), the hammer 9 rotates around the shaft 9b. Since the hammer hand 10 is close to a linear motion, the end 9a of the hammer 9 and the hammer hand 10 are uncoupled immediately before the trigger 3 is pulled, and the hammer 9 is biased by a spring. Reverse rotation of. The impact plate 18 (not shown) is pressed by the momentum of the hammer 9, and the impact plate 18 further presses the valve rear end 5 a of the discharge valve 5. The valve 5 pressed against the valve rear end portion 5a moves forward and opens the valve 5 from the gas chamber 7 to the bullet feed nozzle 4, so that the gas reaches the gas passage 4b of the bullet feed nozzle 4, and the bullet feed nozzle 4 4 is fired at the tip 4c. In order to open the valve 5, the length and thickness of each member are adjusted so that the particle bullet 17 jumps out vigorously by the gas pressure after the particle bullet 17 is fed into the rubber chamber 15 by the bullet feed nozzle 4.

8 and 9 are perspective views in which the main part viewed from the same position as in FIG. 6 is cut away. When an operating handle (not shown) is operated to move backward, the operating handle contacts the bolt 2 and moves backward and forward with a direction in which the operating handle and the bolt 2 are moved forward and backward by projections (not shown) provided to each other. , The bolt 2 is rotated counterclockwise. Since the rear end portion 4a of the bullet feed nozzle 4 is provided off the axis of rotation of the bolt 2, the engagement between the trigger end portion 3c and the rear end portion 4a of the bullet feed nozzle 4 is achieved by rotating the bolt 2. The combination is released and the state shifts to the state shown in FIGS.

When the operating handle is further moved backward from the state of FIG. 8, the engagement between the trigger end 3c and the rear end 4a of the bullet feed nozzle 4 is released. Without being obstructed by 3c, the operating handle is moved backward and the bolt 2 can be pulled backward to the bolt action position shown in FIG.

In the above description, the bolt 2 is rotated counterclockwise when viewed from the rear with the direction of movement of the bolt 2 in the front-rear direction as an axis, but the same effect can be obtained even if the bolt 2 is rotated counterclockwise.

Therefore, the configuration of the second embodiment has a configuration in which the rod 6 is unnecessary as compared with the configuration of the first embodiment, so that the configuration can be simplified and the cost can be reduced.

Further, this mechanism can move the bolt 2 to the bolt action position without deteriorating the appearance.

In addition, in the state of FIG. 9, since the bolt 2 is completely moved to the bolt action position and does not have any trouble other than the bolt 2, the feeding and loading from the ejection port opened by the movement of the bolt 2, The magazine can be attached and detached.

FIGS. 10-13 is the perspective view which expanded and cut off the principal part of Example 3 of this invention. In the second embodiment, in order to avoid the trigger end portion 3c, the bolt 2 rotates counterclockwise as viewed from the rear with the direction in which the bolt 2 moves back and forth as an axis, whereas in the third embodiment, the bolt 2 itself However, it is a configuration in which the gun 2 is held up and escapes upward along the direction in which the bolt 2 moves back and forth. Since other configurations are the same as those described in the second embodiment, detailed description thereof is omitted, and the same reference numerals as those in the first embodiment are used.

In order to open the valve 5, the trigger 3 is interlocked with the respective members in the order of the hammer hand 10, the hammer 9, and the impact plate 18, and the trigger end 3 c is disposed behind the rear end 4 a of the bullet feed nozzle 4. Is done. FIG. 11 is a cutaway perspective view of the main part viewed from the same position as FIG. 10 and shows a state in which the trigger 3 is pulled for firing. When the trigger 3 is pulled, the trigger 3 rotates about the trigger shaft 3b, the trigger end 3c presses the rear end 4a of the bullet feed nozzle 4, and the bullet feed nozzle tip 4c grips the grain bullet 17, The particle bullet 17 is fed into the chamber 15.

By pulling the trigger 3, the hammer hand 10 (not shown) is moved forward simultaneously with the operation of feeding the particle bullet 17 into the chamber 15. Since the hammer hand 10 presses the end 9a of the hammer 9 (not shown), the hammer 9 rotates about the hammer shaft 9b. Since the hammer hand 10 is close to a linear motion, the end 9a of the hammer 9 and the hammer hand 10 are uncoupled immediately before the trigger 3 is pulled, and the hammer 9 is biased by a spring. Reverse rotation of. The impact plate 18 (not shown) is pressed by the momentum of the hammer 9, and the impact plate 18 further presses the valve rear end 5 a of the discharge valve 5. The valve 5 pressed against the rear end 5 a moves forward and opens the valve 5 from the gas chamber 7 to the bullet feed nozzle 4, so that the gas reaches the gas passage 4 b of the bullet feed nozzle 4 and the bullet feed nozzle 4. The particle bullet 17 of the tip part 4c is fired. In order to open the valve 5, the length and thickness of each member are adjusted so that the particle bullet 17 jumps out vigorously by the gas pressure after the particle bullet 17 is fed into the rubber chamber 15 by the bullet feed nozzle 4.

12 and 13 are further perspective views in which the main part viewed from the same position as in FIG. 10 is cut away. When an operating handle (not shown) is operated so as to move backward, the operating handle contacts the bolt 2 and the direction in which the operating handle and the bolt 2 are moved forward and backward by a projection (not shown) provided between the operating handle and the bolt 2 is an axis. Bolt 2 lifts in the direction. Since the bullet feed nozzle 4 is provided on the bolt 2 that moves upward, the upward movement of the bolt 4 releases the engagement between the trigger end 3c and the rear end 4a of the bullet feed nozzle 4 as shown in FIG. To the state shown in FIG.

When the operating handle is further moved backward from the state shown in FIG. 12, the engagement between the trigger end 3c and the rear end 4a of the bullet feed nozzle 4 is released. Without being obstructed by 3c, the operating handle is moved backward and the bolt 2 can be pulled backward to the bolt action position shown in FIG.

Therefore, compared to the first embodiment, the third embodiment can reduce the cost because the number of parts is reduced, and the third embodiment can be simplified because the bolt 2 does not rotate.

In addition, this mechanism can move the bolt 2 to the bolt action position without deteriorating the appearance.

Further, in the state shown in FIG. 13, the bolt 2 is completely moved to the bolt action position, and there is no trouble other than the bolt 2, so that the bullet 2 is loaded and loaded from the ejection port opened by the movement of the bolt 2. The magazine can be attached and detached.

14-17 is the perspective view which expanded and cut off the principal part of Example 4 of this invention. In the first embodiment, the bolt 2 is rotated counterclockwise as viewed from the rear with the direction of moving forward and backward of the bolt 2 as the axis, and the rod 6 is avoided. The bolt 2 rotates counterclockwise as viewed from the rear and the bolt projection 2a moves downward with the rod 6 moving in the front and rear direction of the bolt 2 as a shaft. In this configuration, the engagement of the rod 6 is released. Since other configurations are the same as those described in the first embodiment, detailed description thereof is omitted, and the same reference numerals as those in the first embodiment are used.

In order to open the valve 5, the trigger 3 is interlocked with each member in the order of a hammer hand 10 (not shown), a hammer 9, and an impact plate 18 (not shown) and is connected to the rod 6. The rod 6 is disposed at the rear end 4 a of the bullet feed nozzle 4. FIG. 15 is a cutaway perspective view of the main part viewed from the same position as FIG. 14 and shows a state in which the trigger 3 is pulled for firing. When the trigger 3 is pulled, the trigger 3 rotates about the rigger shaft 3b to move the rod 6 forward. The rod 6 presses the rear end portion 4 a of the bullet feed nozzle 4, the bullet feed nozzle tip portion 4 c holds the grain bullet 17, and feeds the grain bullet 17 into the chamber 15.

The trigger 3 moves the rod 6 forward and simultaneously moves a hammer hand 10 (not shown) forward. Since the hammer hand 10 presses the end 9a of the hammer 9 (not shown), the hammer 9 rotates about the hammer shaft 9b. Since the hammer hand 10 is close to a linear motion, the end 9a of the hammer 9 and the hammer hand 10 are uncoupled immediately before the trigger 3 is pulled, and the hammer 9 is biased by a spring. Rotate in the opposite direction. The impact plate 18 (not shown) is pressed by the momentum of the hammer 9, and the impact plate 18 further presses the valve rear end 5 a of the discharge valve 5. The valve 5 pressed against the rear end 5 a moves forward and opens the valve 5 from the gas chamber 7 to the bullet feed nozzle 4, so that the gas reaches the gas passage 4 b of the bullet feed nozzle 4 and the bullet feed nozzle 4. The particle bullet 17 of the tip part 4c is fired. In order to open the valve 5, the length and thickness of each member are adjusted so that the particle bullet 17 jumps out vigorously by the gas pressure after the particle bullet 17 is fed into the rubber chamber 15 by the bullet feed nozzle 4.

FIGS. 16 and 17 are further perspective views in which the main part viewed from the same position as in FIG. 14 is cut away. When an operating handle (not shown) is operated to move backward, the operating handle contacts the bolt 2 and moves backward and forward with a direction in which the operating handle and the bolt 2 are moved forward and backward by projections (not shown) provided to each other. , The bolt 2 is rotated counterclockwise. The state shown in FIGS. 14 to 16 when the bolt projection 2a moves the rod 6 downward with the direction in which the rod 6 moves back and forth of the bolt 2 as an axis, thereby disengaging the bullet feed nozzle 4 and the rod 6 from each other. Migrate to

When the operating handle is further moved backward from the state of FIG. 16, the engagement between the rod 6 and the rear end 4 a of the bullet feed nozzle 4 is released, so that the bolt 2 is obstructed by the rod 6. Without being moved, the operating handle is moved backward, and the bolt 2 can be pulled backward to the bolt action position shown in FIG.

In the above description, the bolt 2 rotates counterclockwise as viewed from the rear with the direction of movement of the bolt 2 back and forth as an axis, but the same effect can be obtained even if the bolt 2 rotates counterclockwise.

Therefore, since the guide base 22 trigger flexible base part 23 and the like are reduced as compared with the first embodiment, the efficiency of reducing parts and cost can be expected.

In addition, this mechanism can move the bolt 2 to the bolt action position without deteriorating the appearance.

Further, in the state shown in FIG. 17, the bolt 2 is completely moved to the bolt action position, and there is no trouble other than the bolt 2, so that the bullet 2 is loaded and loaded from the ejection port opened by the movement of the bolt 2. The magazine can be attached and detached.

FIGS. 18-21 is the perspective view which expanded and cut off the principal part of Example 5 of this invention. In the first embodiment, the projection provided on the operating handle 12 is opposed to the rod 6 being avoided by rotating the bolt 2 counterclockwise when viewed from the rear with the direction of movement of the bolt 2 as the axis. The portion 12a is configured to release the engagement between the bullet feeding nozzle 4 and the rod 6 by moving the projection 6a of the rod 6 downward with the direction of moving the projection 6a of the bolt 2 back and forth as an axis. Since other configurations are the same as those described in the first embodiment, detailed description thereof is omitted, and the same reference numerals as those in the first embodiment are used.

In order to open the valve 5, the trigger 3 is linked to the respective members in the order of a hammer hand 10, a hammer 9 and an impact plate 18 (not shown) and is connected to the rod 6. The rod 6 is disposed at the rear end 4 a of the bullet feed nozzle 4. FIG. 15 is a cutaway perspective view of the main part viewed from the same position as FIG. 14 and shows a state in which the trigger 3 is pulled for firing. When the trigger 3 is pulled, the trigger 3 rotates around the trigger shaft 3b to move the rod 6 forward. The rod 6 presses the rear end 4 a of the bullet feed nozzle 4, the tip 4 c holds the grain bullet 17, and feeds the grain bullet 17 into the chamber 15.

The trigger 3 moves the rod 6 forward and simultaneously moves a hammer hand 10 (not shown) forward. Since the hammer hand 10 presses the end 9a of the hammer 9 (not shown), the hammer 9 rotates about the hammer shaft 9b. Since the hammer hand 10 is close to a linear motion, the end 9a of the hammer 9 and the hammer hand 10 are uncoupled immediately before the trigger 3 is pulled, and the hammer 9 is biased by a spring. Rotate in reverse to the description. The impact plate 18 (not shown) is pressed by the momentum of the hammer 9, and the impact plate 18 further presses the valve rear end 5 a of the discharge valve 5. The valve 5 pressed against the rear end 5 a moves forward and opens the valve 5 from the gas chamber 7 to the bullet feed nozzle 4, so that the gas reaches the gas passage 4 b of the bullet feed nozzle 4 and the bullet feed nozzle 4. The particle bullet 17 of the tip part 4c is fired. In order to open the valve 5, the length and thickness of each member are adjusted so that the particle bullet 17 jumps out vigorously by the gas pressure after the particle bullet 17 is fed into the rubber chamber 15 by the bullet feed nozzle 4.

20 and 21 are further perspective views in which the main part viewed from the same position as in FIG. 18 is cut away. When the operating handle 12 is operated to move backward, the projection 12a provided on the operating handle 12 moves the projection 6a of the rod 6 downward about the direction in which the projection 6a of the rod 6 moves back and forth. The engagement between the bullet feed nozzle 4 and the rod 6 is released, and the state shown in FIGS.

When the operating handle 12 is further moved backward from the state shown in FIG. 20 where the engagement between the bullet feed nozzle 4 and the rod 6 is released, the engagement with the rear end portion 4a of the bullet feed nozzle 4 is released. Thus, the bolt 2 can be moved rearward by the operating handle without being obstructed by the rod 6, and the bolt 2 can be pulled backward to the bolt action position shown in FIG.

Therefore, it is more effective when the bolt 2 cannot perform a rotational movement or a movement of shifting the shaft as compared with the first embodiment, the second embodiment, the third embodiment, and the fourth embodiment.

In addition, this mechanism can move the bolt 2 to the bolt action position without deteriorating the appearance.

Further, in the state shown in FIG. 21, the bolt 2 is completely moved to the bolt action position, and there is no trouble other than the bolt 2, so that the bullet 2 is loaded and loaded from the ejection port opened by the movement of the bolt 2. The magazine can be attached and detached.

22-24 is the perspective view which notched and expanded the principal part of Example 6 of this invention. In the first embodiment, the bullet feed nozzle 4 is directly struck by the rod 6, but the trigger 3 presses the end 24 b of the cam 24 to press the cam 24 around the rotating shaft 24 a of the cam 2. It is the structure which rotates and presses the edge part 4d of the bullet feed nozzle 4. FIG. Since other configurations are the same as those described in the first embodiment, detailed description thereof is omitted, and the same reference numerals as those in the first embodiment are used for the description.

In order to open the valve 5, the trigger 3 is interlocked with the respective members in the order of a hammer hand 10, a hammer 9, and an impact plate 18 (not shown). Press. FIG. 23 is a cutaway perspective view of the main part seen from the same position as FIG. 22 and shows a state in which the trigger 3 is pulled for firing. When the trigger 3 is pulled, the trigger 3 rotates about the trigger shaft 3 b, and the arc-shaped cam 24 is pressed about the cam end 24 b and rotates about the cam rotation shaft 24 a provided below the bolt 2. The cam end 24 c presses the rear end 4 d of the bullet feed nozzle 4, the tip 4 c grips the grain bullet 17, and feeds the grain bullet 17 into the chamber 15.

The trigger 3 rotates the cam 24 and simultaneously moves the hammer hand 10 (not shown) forward. Since the hammer hand 10 presses the end 9a of the hammer 9 (not shown), the hammer 9 rotates about the hammer shaft 9b. Since the hammer hand 10 is close to a linear motion, the end 9a of the hammer 9 and the hammer hand 10 are uncoupled immediately before the trigger 3 is pulled, and the hammer 9 is biased by a spring. It rotates in the opposite direction of rotation. The impact plate 18 (not shown) is pressed by the momentum of the hammer 9, and the impact plate 18 further presses the valve rear end 5 a of the discharge valve 5. The valve 5 pressed against the rear end 5 a moves forward and opens the valve 5 from the gas chamber 7 to the bullet feed nozzle 4, so that the gas reaches the gas passage 4 b of the bullet feed nozzle 4 and the bullet feed nozzle 4. The particle bullet 17 of the tip part 4c is fired. In order to open the valve 5, the length and thickness of each member are adjusted so that the particle bullet 17 jumps out vigorously by the gas pressure after the particle bullet 17 is fed into the rubber chamber 15 by the bullet feed nozzle 4.

FIGS. 23 and 24 are perspective views in which the main part viewed from the same position as in FIG. 22 is cut away.
When the trigger return spring (not shown) returns the trigger 3 to a predetermined position, the bolt 2 can be operated so as to move backward because there is no portion caught on the trigger end 3d when the trigger 3 is not touched. The state shifts from 22 to the state shown in FIG.

Therefore, it is effective when the bolt 2 cannot rotate or move its axis in the same manner as in the fifth embodiment, and is simpler than the fourth embodiment and can be expected to reduce costs.

In addition, this mechanism can move the bolt 2 to the bolt action position without deteriorating the appearance.

Furthermore, in the state of FIG. 24, the bolt 2 is completely moved to the bolt action position, and there is no trouble other than the bolt 2, so that the bullet 2 is loaded and loaded from the ejection port opened by the movement of the bolt 2. The magazine can be attached and detached.

25 to 28 are enlarged perspective views of the essential parts of the seventh embodiment of the present invention. In the first embodiment, the rod 2 is avoided by rotating the bolt 2 counterclockwise as viewed from the rear with the direction of movement of the bolt 2 in the front-rear direction, whereas the recess 2b of the bolt 2 is locked. By moving the end 25a of the lug 25 downward with the direction of movement of the bolt 2 back and forth as an axis, the rod 6 is moved in the direction in which the end 25b of the locking lug 25 moves back and forth of the bolt 2. It is the structure which cancels | releases engagement with the bullet feed nozzle 4 and the rod 6 by making it move to a downward direction as an axis | shaft. Since other configurations are the same as those described in the first embodiment, detailed description thereof is omitted, and the same reference numerals as those in the first embodiment are used for the description.

In order to open the valve 5, the trigger 3 is interlocked with the respective members in the order of a hammer hand 10, a hammer 9 and an impact plate 18 (not shown) and is also connected to the rod 6. The rod 6 is disposed behind the bullet feed nozzle 4.
FIG. 26 is a cutaway perspective view of the main part seen from the same position as FIG. 25, and shows a state in which the trigger 3 is pulled for firing. When the trigger 3 is pulled, the trigger 3 rotates around the trigger shaft 3b to move the rod 6 forward. The rod 6 presses the rear end portion 4 a of the bullet feed nozzle 4, the bullet feed nozzle tip portion 4 c holds the grain bullet 17, and feeds the grain bullet 17 into the chamber 15.

The trigger 3 moves the rod 6 forward and simultaneously moves a hammer hand 10 (not shown) forward. Since the hammer hand 10 presses the end 9a of the hammer 9 (not shown), the hammer 9 rotates about the hammer shaft 9b. Since the hammer hand 10 is close to a linear motion, the end 9a of the hammer 9 and the hammer hand 10 are uncoupled immediately before the trigger 3 is pulled, and the hammer 9 is biased by a spring. Reverse the description. The impact plate 18 (not shown) is pressed by the momentum of the hammer 9, and the impact plate 18 further presses the valve rear end 5 a of the discharge valve 5. The valve 5 pressed against the rear end 5 a moves forward and opens the valve 5 from the gas chamber 7 to the bullet feed nozzle 4, so that the gas reaches the gas passage 4 b of the bullet feed nozzle 4 and the bullet feed nozzle 4. The particle bullet 17 of the tip part 4c is fired. In order to open the valve 5, the length and thickness of each member are adjusted so that the particle bullet 17 jumps out vigorously by the gas pressure after the particle bullet 17 is fed into the rubber chamber 15 by the bullet feed nozzle 4.

27 and 28 are perspective views in which the main part viewed from the same position as in FIG. 25 is cut away. When the bolt 2 is operated so as to move backward, when the end 25a of the locking lug 25 that has entered the recess 2b of the bolt 2 is moved downward about the direction of moving the bolt 2 back and forth, the locking lug 25, when the rod 25 is moved downward about the direction in which the rod 2 is moved forward and backward of the bolt 2, the engagement between the bullet feed nozzle 4 and the rod 6 is released, and FIGS. Transition to the indicated state.

When the bolt 2 is further moved backward from the state of FIG. 27 in which the engagement with the bullet feed nozzle 4 is released, the engagement between the rear end portion 4a of the bullet feed nozzle 4 and the rod 6 is released. Thus, the bolt 2 can be moved rearward by being moved by the operating handle without being obstructed by the rod 6, and the bolt 2 can be pulled backward to the bolt action position shown in FIG.

Therefore, the mechanism as in the seventh embodiment can be used as it is in an actual gun as in the seventh embodiment in which the locking lug 25 is provided on the bolt 2 or a slide (not shown).

In addition, this mechanism can move the bolt 2 to the bolt action position without deteriorating the appearance.

Further, in the state of FIG. 28, the bolt 2 is completely moved to the bolt action position, and there is no trouble other than the bolt 2, so that the bullet 2 is loaded and loaded from the ejection port opened by the movement of the bolt 2. The magazine can be attached and detached.

FIGS. 29-32 is the perspective view which expanded and cut off the principal part of Example 8 of this invention. In the first embodiment, the rod 2 is avoided by rotating the bolt 2 counterclockwise as viewed from the rear with the direction of movement of the bolt 2 in the front-rear direction as opposed to the disconnect latch 26 of the rod 6. The rod projection 6b is configured to release the engagement between the bullet feed nozzle 4 and the rod 6 by moving the rod projection 6b downward about the direction in which the bolt 2 is moved forward and backward. Since other configurations are the same as those described in the first embodiment, detailed description thereof is omitted, and the same reference numerals as those in the first embodiment are used.

In order to open the valve 5, the trigger 3 is interlocked with the respective members in the order of a hammer hand 10, a hammer 9 and an impact plate 18 (not shown) and is also connected to the rod 6. The rod 6 is disposed behind the bullet feed nozzle 4. FIG. 30 is a cutaway perspective view of the main part viewed from the same position as FIG. 29, and shows a state in which the trigger 3 is pulled for firing. When the trigger 3 is pulled, the trigger 3 rotates around the trigger shaft 3b to move the rod 6 forward. The rod 6 presses the rear end 4 a of the bullet feed nozzle 4, the tip 4 c holds the grain bullet 17, and feeds the grain bullet 17 into the chamber 15.

The trigger 3 moves the rod 6 forward and simultaneously moves a hammer hand 10 (not shown) forward. Since the hammer hand 10 presses the end 9a of the hammer 9 (not shown), the hammer 9 rotates about the hammer shaft 9b.
Since the hammer hand 10 is close to a linear motion, the end 9a of the hammer 9 and the hammer hand 10 are uncoupled immediately before the trigger 3 is pulled, and the hammer 9 is biased by a spring. Reverse the description. The impact plate 18 (not shown) is pressed by the momentum of the hammer 9, and the impact plate 18 further presses the valve rear end 5 a of the discharge valve 5.
The valve 5 pressed against the rear end 5 a moves forward and opens the valve 5 from the gas chamber 7 to the bullet feed nozzle 4, so that the gas reaches the gas passage 4 b of the bullet feed nozzle 4 and the bullet feed nozzle 4. The particle bullet 17 of the tip part 4c is fired. In order to open the valve 5, the length and thickness of each member are adjusted so that the particle bullet 17 jumps out vigorously by the gas pressure after the particle bullet 17 is fed into the rubber chamber 15 by the bullet feed nozzle 4.

FIGS. 31 and 32 are further perspective views in which the main part viewed from the same position as in FIG. 29 is cut away. When the bolt 2 is operated so as to move backward, the outer barrel 27 is also swung back together with the concave-convex portion 27a of the outer barrel 27 entering the concave-convex portion 2c of the bolt 2.
When the outer barrel 27 moves rearward, the end portion 26a of the disconnect latch 26 is pushed, and the disconnect latch 26 moves rearward.
From a receiver 1 (not shown), a rod-shaped part (not shown) serving as a guide has a right angle with the outer barrel 27 in a groove portion 27b of the outer barrel 27 that is inclined with respect to the direction in which the bolt 2 moves back and forth. The outer barrel 27 moves downward with the rod-shaped part serving as a guide from the incoming receiver 1 as a guide and the direction of movement in the front and rear of the bolt 2 as an axis.
When the disconnect latch 26 moves rearward, the end 26b of the disconnect latch 26 moves the rod projection 6b downward about the direction in which the rod protrusion 6b moves back and forth of the bolt 2, thereby causing the bullet feed nozzle 4 and the rod 6 to move downward. Is disengaged. At the same time as the engagement between the bullet feed nozzle 4 and the rod 6 is released, the water barrel 27 escapes downward with the direction of movement of the bolt 2 in the front-rear direction, so the concave-convex portion 2c of the bolt 2 and the concave-convex portion of the outer barrel 27 The meshing of 27a is also released.

When the bolt 2 is further moved backward from the state shown in FIG. 31 where the engagement with the bullet feed nozzle 4 is released, the engagement between the rear end portion 4a of the bullet feed nozzle 4 and the rod 6 is released. Further, since the engagement of the uneven portion 2c of the bolt 2 and the uneven portion 27a of the outer barrel 27 is also released, the bolt 2 is shown in FIG. 32 without being obstructed by the uneven portion 27a of the rod 6 or the outer barrel 27. The bolt 2 can be pulled backward to the action position.

Therefore, the mechanism as in the eighth embodiment can be used as it is in a type that uses an actual gun and performs a short recoil as in the eighth embodiment.

In addition, this mechanism can move the bolt 2 to the bolt action position without deteriorating the appearance.

Further, in the state of FIG. 32, the bolt 2 is completely moved to the bolt action position, and there is no trouble other than the bolt 2, so that the bullet 2 is loaded and loaded from the ejection port opened by the movement of the bolt 2. The magazine can be attached and detached.

As mentioned above, although each Example of Examples 1-8 showed only the case of the engine part of a gas gun, the structure of each Example is applicable also to the Example of an air gun. Similarly, it can be applied to the engine part of a gun using an electromagnetic valve. Further, the gun can be applied to all forms such as a rifle, a hand gun, a submachine gun, or a machine gun.

In addition, the arrangement and configuration of each member can be appropriately modified and applied without departing from the spirit of the invention described in the claims without being limited to the configuration shown in each of the above embodiments. For example, the present invention can be applied to a configuration having a plurality of barrels, a configuration having an electromagnetic valve, and a configuration having two triggers.

Further, as in the third embodiment described above, the bolt 2 is lifted upward with the direction of movement of the bolt 2 back and forth as an axis, and the engagement with the bullet feed nozzle 4 is released. Even if the engagement is released by moving in the downward direction, the right direction, the left direction, or other oblique directions with the direction of moving in the direction of the axis as the axis, it can be applied.
In the above description, the trigger 3 presses the rod 6 and further presses the bullet feed nozzle 4, or the trigger 3 directly presses the bullet feed nozzle 4. Up to 4, it can be adapted to any number of parts corresponding to the rod 6.
Furthermore, although it may be avoided in either direction about the direction of movement of the bolt 2 before and after, the rod 6 is guided to the rear of the bullet feed nozzle 4a only when the trigger 3 is pulled by a guide groove or projection of a frame (not shown). Due to the structure in which the bullet feed nozzle 4 is moved, when the trigger 3 is not pulled, the bolt 2 can be moved as it is to the bolt action position without avoiding either direction around the direction of movement of the bolt 2.

Also, in the fifth embodiment described above, the projection nozzle 12a is provided by moving the projection 12a provided on the operating handle 12 downward with the projection 6a of the rod 6 moving forward and backward of the bolt 2. 4 and the rod 6 are disengaged, but the engagement is disengaged by moving upward, rightward, leftward or other oblique directions with the direction of movement of the bolt 2 back and forth as the axis. Can also be adapted. Also, other parts attached to the operating handle 12 can be adapted if they have the same function as the operating handle protrusion 12a.

Further, in the seventh embodiment described above, when the end 25a of the locking lug 25 is moved downward about the direction of moving the bolt 2 in the front-rear direction, the end 25b of the locking lug 25 causes the rod 6 to move. The engagement between the bullet feed nozzle 4 and the rod 6 is released by moving downward about the direction of movement of the bolt 2 as an axis, but the right direction about the direction of movement of the bolt 2 before and after, It can also be adapted to move leftward or other diagonal directions.

Further, in the eighth embodiment described above, the end 26b of the disconnect latch 26 moves the rod protrusion 6b downward about the direction in which the rod protrusion 6b moves back and forth of the bolt 2 as an axis, thereby causing the bullet feed nozzle 4 and the rod 6 to move downward. However, it can also be applied by moving the rod protrusion 6b in the right direction, left direction, or other oblique direction with the direction in which the rod protrusion 6b is moved back and forth of the bolt 2 as an axis.
Furthermore, in the eighth embodiment described above, the simulated gun reproduces the short recoil model. However, the present invention is not limited to the short recoil but can be applied to a blowback such as blow forward or long recoil.
