Description

The present invention relates to an empty shot prevention device in an electric gun.

A so-called electric gun uses the rotation of a motor to drive a piston in a cylinder, and the driving force of the piston injects air in the cylinder to fire a bullet. A trigger drives the motor. It is for turning on the electric switch to do.

Therefore, as long as the trigger is being pulled, the motor continues to be driven because the electric switch is kept on. Therefore, the piston movement does not stop, and even if there are no bullets in the magazine, the air in the cylinder is continuously injected and the so-called empty shooting is continued.

Therefore, Japanese Patent Application Laid-Open No. 2010-25501 filed by the present applicant discloses a mechanical energization stop device for an electric gun. The above device is movably arranged in the bullet feed path as a device for interrupting the circuit of the drive unit that fires the bullet and stopping the energization when there is no bullet in the bullet feed path leading to the bullet loading portion at the rear of the gun cavity. The tappet member that is urged to send a bullet to the bullet loading part, the follower member that engages with a part of the tappet member side at one end and interlocks with the movement, and the follower member is energized as it moves. A cut-off member that can move from the time position to the shut-off position and that engages with the tappet member in the process of moving to the shut-off position and turns off the switch as the tappet member moves, and the drive unit With the tappet member that has a portion that opens the bullet feed port of the bullet feed path that retracts with the movement of the piston and leads to the bullet loading portion and that moves the cutoff member by the urging force in the direction of closing the bullet feed port. The switch is provided with the above-mentioned switch that moves by engaging with the cutoff member to open the contact and closes by the reset operation.

However, the cylinder, the piston, and the engine part such as the gear that drives the cylinder in the electric gun are arranged in a predetermined housing, and they are unitized. Although they are called mechanical boxes, it is necessary to incorporate the above-mentioned device in the unitized mechanical box.

Further, since the conventional mechanical box does not have a space for incorporating the above device, the mechanical box itself must be newly manufactured. Also, depending on the type of electric gun, even if it is newly manufactured, there may not be enough space to incorporate the above device in the mechanical box, and it is realistic to apply the above mechanical energization stop device to all mechanical boxes. is not.

The electric gun 10 having the empty shot prevention device 200 in this embodiment will be described. The electric gun 10 is provided with a switch 201 outside the housing 16 in the mechanical box described later, in addition to the first contact 21 that contacts and energizes when the trigger 20 described later is pulled, and the bullet G in the magazine portion 500 is provided. In order to prevent so-called empty shooting, the energization stop unit 202 is arranged, and the energization stop unit 202 disconnects the switch 201 (see FIGS. 1 and 2).

The first contact 21 and the switch 201 are connected in series by wiring S, and when both the first contact 21 and the switch 201 are energized, a bullet G is fired and the bullet G disappears. The energization stop portion 202 can prevent the empty shot by either cutting off the energization of the switch 201 or returning the trigger 20 that has been pulled (see FIGS. 1 and 2).

First, the structure of the engine unit 15 for firing the bullet G in the electric gun 10 will be described. The engine unit 15 is arranged in the housing 16. Further, the engine unit 15 includes a trigger 20, a first contact 21, a motor 22, a motor gear 23, a bevel gear 24, a gear 25, a sector gear 26, a piston 30, a rack portion 31 included in the piston 30, and a rack portion 31 thereof. It has a spring 32 that urges the piston 30 in the −x direction. Here, the housing 16 having the engine unit 15 may be referred to as a mechanical box.

When a user (not shown) pulls the trigger 20, the first contact 21 comes into contact, electricity from the battery 100 flows to the motor 22, and the motor 22 rotates. The rotation causes the motor gear 23 arranged on the output shaft of the motor 22 to rotate, the bevel gear 24 that meshes with the motor gear 23 rotates, the gear 25 that meshes with the bevel gear 24 rotates, and the sector gear 26 that meshes with the gear 25 rotates. To do.

The sector gear 26 meshes with the rack portion 31 of the piston 30, so that the piston 30 moves in the + x direction. Along with that, the piston 30 compresses the spring 32.

Since the sector gear 26 has a toothless portion that does not have a part of the gear teeth, when the toothless portion of the sector gear 26 rotates to a position facing the rack portion 31, the rack portion 31 and the sector gear 26 The engagement with the sector gear 26 is disengaged, and the force that the spring 32 recovers to its natural length causes the piston 30 arranged in the cylinder 40 to rapidly move in the −x direction, and the air in the cylinder 40 is sent to the tip of the nozzle 33. It injects into a pre-arranged bullet G and fires the bullet G with the air.

Further, the electric gun 10 is provided with a recoil shock generation mechanism 50 for generating a so-called recoil shock for simulating the impact generated by the reaction at the time of firing a bullet generated in the actual gun. Therefore, this will also be described. The recoil shock generation mechanism 50 has a piston engaging portion 51 in the piston 30 and a recoil weight 52 that engages with the piston engaging portion 51, and the recoil weight 52 is urged in the −x direction by the recoil spring 53. Has been done. The recoil weight 52 preferably has a predetermined mass in order to reproduce the impact in a simulated manner.

As described above, the piston 30 arranged in the cylinder 40 rapidly moves in the −x direction, and the air in the cylinder 40 is injected into the bullet G previously arranged at the tip of the nozzle 33, and the air is used. Fire the bullet G. At that time, the recoil weight 52 that engages the piston engaging portion 51 and the piston engaging portion 51 of the piston 30 is rapidly restored in the same manner as the piston 30 by the force that the accumulated recoil spring 53 recovers to its natural length. It moves in the −x direction, and the recoil weight 52 collides with the tip portion 54 to generate an impact, and a so-called recoil shock is obtained.

After that, as the piston 30 moves in the + x direction again, the recoil weight 52 that engages with the piston engaging portion 51 in the piston 30 also moves in the + x direction to accumulate the recoil spring 53.

After that, again, the piston 30 arranged in the cylinder 40 rapidly moves in the −x direction in the same manner as described above, and the accumulated recoil spring 53 obtains a recoil shock again by the force of recovering to its natural length. In this way, when the trigger 20 is pulled, a so-called recoil shock is obtained every time the bullet G is fired. It also has a recoil bar 60 that is connected to the recoil weight 52. Further, the electric gun 10 has the recoil weight 52, the recoil bar 60 and the recoil plate 61 connected to the recoil bar 60, and the recoil weight 52, the recoil bar 60 and the recoil plate 61 are connected to each other. It may be referred to as a piston interlocking unit 250. The piston interlocking portion 250 is literally interlocked with the movement of the piston 30, and reciprocates in the −x direction and the + x direction in response to the firing of the bullet G.

As described above, the empty shot prevention device 200 in the present embodiment has a switch 201 different from the first contact 21 connected in series by the wiring S to the first contact 21 in the mechanical box as described above. The bullet detection device 300 detects that the bullet G has been shot outside the 16 and the magazine G has disappeared, and the switch 201 is cut by the switch disconnection portion 270 in the energization stop portion 202. The switch cutting portion 270 is cut by the piston interlocking portion 250 driven by the movement of the piston 30. Therefore, as described above, even if the trigger 20 is pulled and the first contact 21 is still in contact, the switch 201 connected in series with the first contact 21 is disconnected to prevent empty shooting. You can do it.

Therefore, the bullet detection device 300 for detecting that the bullet G has disappeared in the magazine portion 500 will be described. The bullet detection device 300 is arranged in the magazine portion 500. Here, the configuration of the magazine portion 500 will be described first, and then the bullet detection device 300 will be described.

The magazine portion 500 has a magazine body portion 501, which constitutes an outer shell as a magazine that supplies a so-called bullet G to the electric gun 10. Further, the bullet arranging portion 502 serves as a passage for arranging a plurality of bullets G and sending the bullet G inside the electric gun 10, and the width of the bullet arranging portion 502 is equal to the width of the bullet G. It has been set. The bullet arranging portion 502 has a magazine spring 505 for pushing up a plurality of bullets G in the opening 503 direction (+ y direction), and a follower portion 510 urged by the magazine spring 505.

Therefore, the follower unit 510 includes a first follower 511 urged by the magazine spring 505, a second follower 512 urged by the first follower 511, and a third follower urged by the second follower 512. 513, and as described above, the bullet G is always urged in the direction of the opening 503 (+ y direction). That is, the magazine spring 505 presses the first follower 511 in the follower unit 510. Further, the second follower 512 and the first follower 511 have a shaft portion on one side and a bearing portion on the other side, and they are fitted and connected to each other. Therefore, the second follower 512 and the first follower 511 are foldably connected so that the bullet arranging portion 502 can follow the curved shape if it is curved. Further, the third follower 513 is pressed by the second follower 512 by coming into contact with the second follower 512.

The lower end portion 505a of the magazine spring 505 is arranged at the end portion 502a of the bullet arrangement portion 502, and the spring upper end portion 505b of the magazine spring 505 is connected to the first follower 511 in the follower portion 510. Further, when the magazine portion 500 is removed from the electric gun 10 (not shown), a bullet locking portion 515 is arranged to prevent the bullet G from popping out, and is attached in the + x direction by the bullet locking spring 516. It is being pushed.

That is, when a plurality of bullets G are packed in such a magazine portion 500 having the above configuration, the magazine spring 505 is compressed by the plurality of bullets G, and the bullet lock spring 516 is urged in the + x direction. The stop 515 prevents the bullet G located at the top of the plurality of bullets G from popping out, and the plurality of bullets G are arranged in the magazine portion 500. Further, when the magazine 500 is set in the electric gun 10, the bullet locking portion 515 is pressed by the chamber 34 (see FIG. 1) in the −x direction, and the bullet locking portion 515 is pressed in the −x direction. The engagement between the 515 and the bullet G is disengaged. As a result, the bullet G is loaded into the electric gun 10. In FIGS. 3, 4, and 5A, the bullet locking portion 515 is in a state of being disengaged from the bullet G.

In this embodiment, the bullet detection device 300 is arranged in the magazine portion 500, and rotates in response to the rise of the detection engagement portion 301 arranged in the first follower 511 in the follower portion 510 and the detection engagement portion 301. It has a detection rotating unit 310.

The detection rotating portion 310 includes a detection engaged portion 311 and a detection extrusion portion 312, a detection shaft portion 313, and a detection extrusion portion 312 arranged at an angle of approximately 90 degrees with the detection engaged portion 311. It has a thin plate-shaped and triangular first main body portion 330 arranged between the detection shaft portion 313 and the detection shaft portion 313. The detection engaged portion 311, the detection extrusion portion 312, the detection shaft portion 313, and the first main body portion 330 are integrated, and they constitute the detection rotation portion 310. Further, the detection rotation unit 310 rotates so as to swing around the detection shaft unit 313 (see FIG. 3).

When all the bullets G placed in the magazine 500 have been shot, the bullets G placed in the magazine 500 will disappear and the magazine spring 505 will recover to a natural length sufficiently longer than the length of the bullet placement 502. As a result, the first follower 511 in the follower unit 510 is pushed up in the direction of the opening 503.

At the same time, the first follower 511 connected to the spring upper end portion 505b of the magazine spring 505 rises, and the detection engaging portion 301 arranged in the first follower 511 is the detection engaged portion in the detection rotation unit 310. The 311 is rotated counterclockwise, and the detection pushing portion 312 integrated with the detection engaged portion 311 is rotated counterclockwise so as to protrude from the inside of the magazine portion 500. When all the bullets G arranged in the magazine 500 are shot out in this way, the detection and extrusion unit 312 is projected from the magazine 500 to detect that the bullet G has become empty (Fig.). 4). In that case, the upper end portion 513a of the third follower 513 protrudes from the opening 503. In this embodiment, the position where the detection extrusion portion 312 is projected so as to protrude from the inside of the magazine portion 500 is the position opposite to the bullet arrangement portion 502 of the housing 16 in the mechanical box (in the −x direction). (See FIG. 1). That is, the position of the housing 16 in the mechanical box is arranged in the direction of the trigger 20 (in the + x direction) with respect to the bullet arranging portion 502. On the other hand, the detection and extrusion unit 312 of the bullet detection device 300 attempts to detect the presence or absence of a bullet in order to disconnect the switch 201 arranged outside the housing 16, so that the detection and extrusion unit 312 , The bullet arranging portion 502 is arranged at a position (in the −x direction) opposite to the position of the trigger 20.

In addition, in order to stop the function of the bullet detection device 300, the empty shot prevention function stop device 360 is provided. This engages with the second detection shaft portion 350 arranged in the detection engaged portion 311 in the detection rotation unit 310 and the function stop engagement portion 361 in the empty shot prevention function stop device 360, and the detection rotation unit 310. The detection and extrusion unit 312 in the above is not so much projected to the outside of the magazine portion 500, but is substantially kept in the magazine portion 500. As a result, the function of the empty shot prevention device 200, which will be described later, can be stopped, so that even if the bullet G disappears from the bullet arranging portion 502 and becomes empty, so-called empty shot can be performed. This is particularly suitable for users who want to experience only the recoil shock while contributing to safety because the operation of the electric gun equipped with the recoil shock can be confirmed in a state where the bullet G is not filled in the magazine portion 500. is there.

That is, from the state shown in FIG. 4, the empty shot prevention function stop device 360 is slid and moved in the −x direction. 5A and 5B show a state in which the empty shot prevention function stop device 360 is slid and moved in the −x direction. In this state, the position engaging portion 365 in the empty shot prevention function stop device 360 disengages from the engagement with the first groove portion 551 in the magazine portion 500 and engages with the second groove portion 552. At this time, the function stop engaging portion 361 of the empty shot prevention function stop device 360 engages with the second detection shaft portion 350 arranged at the detection engaged portion 311 of the detection rotation unit 310. As described above, the detection rotating unit 310 is pushed down clockwise by the empty shot prevention function stop device 360 on the xy plane of FIG. 5A, and the detection extrusion unit 312 integrated with the detection engaged portion 311 is the magazine body. It is in a state of staying in the portion 501 without protruding to the outside.

In such a state, when the bullet G is hit and the bullet G disappears from the bullet arranging portion 502, the follower portion 510 rises as described above and is arranged at the first follower 511 in the follower portion 510. Although the detection engaging portion 301 engages with the detection engaged portion 311 in the detection rotation unit 310, the rotation (counterclockwise rotation in FIG. 5A) of the detection rotation unit 310 stops the empty shot prevention function. It is blocked by the device 360, and the detection pushing portion 312 in the detection rotating portion 310 is substantially kept in the magazine main body portion 501 of the magazine portion 500 without protruding to the outside of the magazine portion 500 so much. In this case, the upper end portion 513a of the third follower 513 does not protrude from the opening 503, and the upper end portion 513a remains in the opening 503.

Further, from the state of FIGS. 5A and 5B, the empty shot prevention function stop device 360 is slid and moved in the + x direction. When the empty shot prevention function stop device 360 is slid and moved in the + x direction, the position engaging portion 365 in the empty shot prevention function stop device 360 disengages from the second groove portion 552 in the magazine portion 500 and engages with the first groove portion 551. To do. At this time, the function stop engaging portion 361 of the empty shot prevention function stop device 360 is disengaged from the second detection shaft portion 350 arranged at the detection engaged portion 311 of the detection rotation unit 310. By moving the empty shot prevention function stop device 360 in this way, the function stop engaging portion 361 in the empty shot prevention function stop device 360 is arranged so as to be disengageable from the detected engaged portion 311 in the detection rotating unit 310. It has been done. Further, the empty shot prevention function stop device 360 has a groove portion 366. As a result, the position engaging portion 365 is elastically deformed in a reconstructably manner, so that the position engaging portion 365 is suitable for engaging with or disengaging from the first groove portion 551 and the second groove portion 552. (See FIGS. 4, 5A and 5B).

In FIG. 5B, the second detection shaft portion 350 has a configuration that protrudes toward the front side of the drawing, and the position engaging portion 365 in the empty shot prevention function stop device 360 engages with the first groove portion 551 in the magazine portion 500. When this happens, the function of the bullet detection device 300 is not stopped, and when it engages with the second groove portion 552, the function of the bullet detection device 300 is stopped (see FIGS. 4, 5A and B).

Next, the empty shot prevention device 200 in the electric gun 10 will be described. As described above, the empty shot prevention device 200 is provided with a switch 201 outside the housing 16 to prevent so-called empty shots when the bullet G of the magazine portion 500 becomes empty. 202 is configured to break the contact of the switch 201. Therefore, in response to the above-mentioned detection and pushing portion 312 protruding, the energization stop portion 202 is operated to cut off the contact of the switch 201 (do not energize).

The energization stop unit 202 is for separating the contacts of the detection receiving unit 210, the piston interlocking unit 250 linked to the movement of the piston 30, and the switch 201 for the detection pushing unit 312 to receive the operation protruding from the magazine unit 500. It has a switch cutting portion 270 of the above (see FIG. 6). The detection receiving unit 210 has a first detection receiving unit 211 and a second detection receiving unit 212, and receives an operation of moving the detection pushing unit 312 in the −x direction, and the first detection receiving unit 211 is In response to the operation of the detection and pushing unit 312 to move in the −x direction, the detection and extrusion unit 312 moves in the −x direction (see FIGS. 6, 7A and B).

The second detection receiving portion 212 is rotatably stopped by the shaft portion 213. The protrusion 212a of the second detection receiving portion 212 is further pressed by the tip portion 211a of the first detection receiving portion 211 that has been pressed by the tip portion 312a of the detection extrusion portion 312. According to FIGS. 8A and 8B which are bottom views, the second detection receiving portion 212 rotates clockwise on the xz plane. As a result, the other end 212b of the second detection receiving portion 212 also rotates clockwise on the xz plane, so that the other end 212b projects into the orbit of the recoil plate 61 that reciprocates from the −x direction to the + x direction. To do. That is, when the piston 30 reciprocates from the −x direction to the + x direction, the recoil plate 61 in the piston interlocking portion 250 interlocking with the piston 30 also reciprocates from the −x direction to the + X direction. Further, as described above, the other end portion 212b projects into the reciprocating orbit. That is, in FIGS. 8A and 8B, by being pressed by the first detection receiving portion 211, the second detection receiving portion 212 exhibits a so-called standing state in which the other end portion 212b is above the drawing, and the other end portion. The 212b projects into the orbit of the recoil plate 61 in the reciprocating motion (−x direction and + x direction).

FIG. 9 is an enlarged side view of the state in which the muzzle of the electric gun 10 is directed to the right in the states of FIGS. 8A and 8B. In this state, the stop plate 280 in the switch cutting portion 270 described later is not engaged with the switch lever 290.

In that state, since the piston 30 is still reciprocating, the other end 212b of the second detection receiving portion 212 in the standing state in FIGS. 8A and 8B is subsequently recoiled in the piston interlocking portion 250 in FIGS. 10A and 10B. Engage with plate 61. As described above, the recoil plate 61 reciprocates from the −x direction to the + x direction, so that the second detection receiving portion 212 engages with the recoil plate 61 and the other end portion of the second detection receiving portion 212. The 212b further operates to rotate clockwise on the xz plane. That is, since the energization has not been cut off yet, the motor 22 rotates and the piston 30 continues to reciprocate. However, the piston interlocking unit 250 that follows the reciprocating motion of the piston 30 receives the second detection. The other end 212b of the portion 212 further rotates clockwise on the xz plane. The spring 214 urges the second detection receiving portion 212 counterclockwise (see FIGS. 10A and 10B).

As a result, the one end portion 212c of the second detection receiving portion 212 also rotates clockwise on the xz plane. Further, the one end portion 212c of the second detection receiving portion 212 in the detection receiving portion 210 rotated clockwise engages with the switch cutting portion 270 to operate the switch cutting portion 270. Further, by the operation of the switch disconnection portion 270, the switch disconnection portion 270 cuts off the contact of the switch 201, that is, disconnects the switch 201 (see FIGS. 8A, 9, 10A, and B).

To further explain this, first, the switch cutting portion 270 has a latch 271, a stop plate 280, and a switch lever 290. Further, the latch spring 272 urges the latch 271 clockwise. With such a configuration, one end 212c of the second detection receiving portion 212 engages with the latch 271 of the switch cutting portion 270, and the one end 212c thereof is opposed to the clockwise urging force of the latch spring 272. Is rotated counterclockwise (see FIGS. 8A, 9, 10A, B, 11).

The latch 271 has a latch convex portion 271a, and the stop plate 280 engaged with the latch convex portion 271a is urged in the −x direction by the stop plate spring 281. Therefore, by rotating the latch 271 counterclockwise, the stop plate 280 whose engagement with the latch convex portion 271a in the latch 271 is disengaged moves in the −x direction. FIG. 11 is a side view of the state in which the muzzle of the electric gun 10 is directed to the right in the states of FIGS. 10A and 10B. By comparing FIG. 9 and FIG. 11, it can be understood that the stop plate 280 is moving in the −x direction.

By moving the stop plate 280 in the −x direction, the switch lever one end 291 of the switch lever 290 is pushed down, and the switch lever other end 292 is pulled up in the + y direction about the switch lever shaft 293. At that time, the convex portion 294 attached to the switch lever shaft portion 293 rotates, lifts the first contact portion 201a of the switch 201, and cuts off the contact with the second contact portion 201b of the switch 201. As a result, the energization of the motor 22 is blocked, and it is possible to prevent the empty shot (see FIG. 11). That is, the detection receiving unit 210 operates the switch disconnection unit 270, and the switch disconnection unit 270 disconnects the switch 201. The switch lever 290 has a switch lever one end portion 291 and a switch lever other end portion 292, and has an obtuse angle of apex, which is a substantially isosceles triangle shape. The switch lever spring 290a urges the switch lever 290 counterclockwise in FIG. As a result, when the bullet G is arranged in the magazine portion 500 or when the empty shot prevention function stop device 360 is functioning, the first contact portion 201a in the switch 201 is pushed down, and the second contact portion 201a in the switch 201 is pressed down. The contact with the contact portion 201b is ensured.

In this way, in the past it was necessary to use a mechanical box equipped with a mechanical energization stop device for a dedicated electric gun, but since the empty shot prevention device can be installed as an independent device from the so-called mechanical box. The existing mechanical box can be used by installing this device in a part with space regardless of the outer shape of the electric gun. Therefore, even if the user keeps pulling the trigger 20 in a state where the bullet G in the magazine is empty after the bullet G has finished shooting, the effect of preventing so-called empty shooting can be achieved. In an electric gun that does not have a magazine, the main body of the electric gun has the same configuration as the bullet detection device, so that the effect of preventing empty shots can be achieved.

In this state, the first contact portion 201a of the switch 201 is lifted by the above-mentioned action of the stop plate 280 and the switch lever 290, and the contact with the second contact portion 201b of the switch 201 is cut off. (See FIG. 11). Therefore, the bolt portion 295 is pulled in the + x direction in order to bring the first contact portion 201a and the second contact portion 201b of the switch 201 into contact again. A user (not shown) pulls the bolt portion 295, and after a certain stroke, the bolt portion 295 engages with the stop plate 280. Since the stop plate 280 engaged with the bolt portion 295 is urged in the −x direction by the stop plate spring 281, the bolt portion 295 is pulled in the + x direction against this urging force ( See FIG. 12).

FIG. 13 is an enlarged bottom view of a state in which the muzzle is directed to the left in the state of FIG. When the magazine portion 500 filled with the bullet G in advance is set in the electric gun 10 and the bolt 295 is pulled in the + x direction as described above, the stop plate 280 also moves in the + x direction and engages with the latch 271 again. The stop plate 280 stays in that position against the stop plate spring 281. The first contact portion 201a of the switch 201 is pushed down and comes into contact with the second contact portion 201b of the switch 201 (see FIGS. 12 and 13). After that, if the trigger 20 is pulled, the bullet G can be fired again. In this embodiment, the recoil shock generation mechanism 50 is provided, but even if this mechanism is not provided, the piston interlocking portion 250 that follows the reciprocating motion of the piston 30 is arranged. It is also possible to carry out the piston 30 itself as the piston interlocking portion 250.
