Description

Anti-collision device for electric gun

The present invention relates to an anti-collision device for an electric gun.

The so-called electric gun drives the piston in the cylinder using the rotation of the motor, and the driving force of the piston ejects the air in the cylinder to fire a bullet, and the trigger drives the motor. To turn on the electrical switch.

Thus, while continuing to pull the trigger, the motor continues to be driven because the electrical switch remains on. Therefore, the piston movement does not stop, and even if the bullet is lost in the magazine, the air in the cylinder continues to be jetted, and so-called "collision" is continued.

Therefore, Japanese Patent Application Laid-Open No. 2010-25501 filed by the present applicant discloses a mechanical power supply stop device for an electric gun. The above device is disposed movably in the ballistic path as a device for interrupting the circuit of the drive unit for firing the bullet when there is no bullet in the ballistic path leading to the bullet section at the rear of the gun cavity. And urging the ball pushing member to send bullets to the bullet part, a follower member engaged with a part of the ball pushing member side at one end and interlocked with the movement, and energization according to the movement of the follower member A cut-off member which is movable from a position when in position to a position when it is blocked and engaged with the tappet member in the process of movement to the position when it is blocked and which turns off the switch along with the movement of the tappet member; The tappet member having a portion for opening the mouthpiece opening of the ballistic feeding path which is retracted with movement of the piston and leads to the shell and moves the cutoff member by an urging force in a direction to close the mouthpiece ,cut off Open contacts and moved by engagement with the wood, it is that configured by a said switch to close the contacts by resetting operation.

However, the cylinder in the electric gun, the piston, and an engine unit such as a gear for driving the cylinder are disposed in a predetermined housing and are unitized. Although they are referred to as mechanical boxes, it is necessary to incorporate the above-described device into the unitized mechanical box.

In addition, since the conventional mechanical box does not have a space for incorporating the above-described device, the mechanical box itself must be newly manufactured. In addition, there are cases where there is not enough space to incorporate the above device into the mechanical box depending on the type of electric gun, even if it is intended to manufacture a new one, and it is realistic to apply the above-mentioned mechanical shutoff device to all mechanical boxes is not.

FIG. 10 is an enlarged bottom view of the electric gun with the muzzle facing left in a state in which the motor is energized again.

The electric gun 10 having the anti-collision device 200 in the present embodiment will be described. The electric gun 10 is provided with a switch 201 on the outside of the casing 16 in the mechanical box to be described later, separately from the first contact 21 which contacts and is energized when the trigger 20 to be described later is pulled. In order to prevent a so-called blowout, the energization stop unit 202 is disposed, 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 the wire S. When both the first contact 21 and the switch 201 are energized, the bullet G is fired and the bullet G disappears. It is possible to prevent overstrike by either or both of the energization stop unit 202 deenergizing the switch 201 and returning the trigger 20 being pulled (see FIGS. 1 and 2).

First, the structure of the engine unit 15 for firing a bullet G in the electric gun 10 will be described. The engine unit 15 is disposed 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, and a rack 31 of the piston 30, and A spring 32 is provided to bias 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 the user (not shown) pulls the trigger 20, the first contact point 21 contacts and electricity from the battery 100 flows to the motor 22, thereby rotating the motor 22. The rotation rotates the motor gear 23 disposed on the output shaft of the motor 22, rotates the bevel gear 24 meshing with the motor gear 23, rotates the gear 25 meshing with the bevel gear 24, and rotates the sector gear 26 meshing with the gear 25 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 having no 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 force with which the sector gear 26 is disengaged and the spring 32 recovers to its natural length causes the piston 30 disposed in the cylinder 40 to move rapidly in the -x direction, and the air in the cylinder 40 to the tip of the nozzle 33 It injects to the bullet G currently arrange | positioned beforehand, and it is what fires the bullet G with the air.

Further, the electric gun 10 is provided with a recoil shock generating mechanism 50 for generating a so-called recoil shock for artificially reproducing an impact caused by a reaction at the time of projectile generated in a real gun. Therefore, this will also be described. The recoil shock generating mechanism 50 has a piston engaging portion 51 of the piston 30 and a recoil weight 52 engaged with the piston engaging portion 51. The recoil weight 52 is biased in the -x direction by the recoil spring 53. It is done. The recoil weight 52 preferably has a predetermined mass in order to simulate an impact in a pseudo manner.

As described above, the piston 30 disposed in the cylinder 40 rapidly moves in the -x direction, and the air in the cylinder 40 is jetted to the bullet G previously disposed at the tip of the nozzle 33 and Fire the bullet G. At that time, the piston engaging portion 51 of the piston 30 and the recoil weight 52 engaged with the piston engaging portion 51 are rapidly restored similarly to the piston 30 by the force of the accumulated recoil spring 53 recovering to the natural length. Moving in the -x direction, the recoil weight 52 collides with the tip 54 to generate an impact, and a so-called recoil shock is obtained.

Thereafter, as the piston 30 moves in the + x direction again, the recoil weight 52 engaged with the piston engaging portion 51 of the piston 30 also moves in the + x direction, and the recoil spring 53 is accumulated.

Thereafter, again, the piston 30 disposed in the cylinder 40 moves rapidly in the -x direction as described above, and the recoil shock is obtained again by the force of the accumulated recoil spring 53 recovering to its natural length. Thus, when the trigger 20 is pulled, so-called recoil shock is obtained each time the bullet G is fired. In addition, it has a recoil bar 60 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 It may be called piston interlocking part 250. The piston interlocking portion 250 literally interlocks 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, in the present embodiment, the anti-collision device 200 includes the switch 201 other than the first contact 21 connected in series by the first contact 21 and the wire S in the mechanical box as described above. The bullet detection device 300 detects that the bullet G has been fired and the bullet G has disappeared in the magazine unit 500, and the switch 201 is disconnected by the switch disconnection unit 270 in the energization stop 202. The switch cut-off portion 270 is cut off by the piston interlocking portion 250 driven by the movement of the piston 30. Therefore, as described above, even if the first contact 21 is kept in contact by pulling the trigger 20, the switch 201 connected in series with the first contact 21 is disconnected, so that the color shooting is prevented. It can be done.

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

The magazine unit 500 has a magazine main body 501, which constitutes an outer shell as a magazine for supplying a so-called bullet G to the electric gun 10. In addition, the bullet arrangement portion 502 arranges a plurality of bullets G and serves as a passage for feeding the bullets G into the interior of the electric gun 10, and the width of the bullet arrangement portion 502 is equal to the width of the bullets G. It is set. The bullet placement portion 502 has a magazine spring 505 for pushing up the plurality of bullets G toward the opening 503 (+ y direction), and a follower portion 510 biased by the magazine spring 505.

Therefore, the follower unit 510 is configured such that the first follower 511 biased by the magazine spring 505, the second follower 512 biased by the first follower 511, and the third follower biased by the second follower 512. 513, and as described above, the bullet G is always biased in the direction (+ y direction) of the opening 503. That is, the magazine spring 505 presses the first follower 511 in the follower portion 510. Further, one of the second follower 512 and the first follower 511 has a shaft portion, and the other has a bearing portion and these are fitted and connected. Therefore, the second follower 512 and the first follower 511 are foldably connected so that the bullet placement portion 502 can follow the curved shape if it is temporarily curved. The third follower 513 is pressed by the second follower 512 by being in contact with the second follower 512.

The lower end portion 505 a of the magazine spring 505 is disposed at the end portion 502 a of the bullet disposition portion 502, and the spring upper end portion 505 b of the magazine spring 505 is connected to the first follower 511 in the follower portion 510. In addition, when the bullet part 500 is removed from the electric gun 10 (not shown), the bullet locking portion 515 is disposed to prevent the bullet G from jumping out, and attached in the + x direction by the bullet locking spring 516. It is powered.

That is, when a plurality of bullets G can be packed in such a magazine portion 500 of the above configuration, the magazine spring 505 is compressed by the plurality of bullets G, and the bullet clutch biased in the + x direction by the bullet locking spring 516 The stoppers 515 prevent the bullets G arranged at the top of the plurality of bullets G from jumping out, and the plurality of bullets G are arranged in the magazine 500. Also, when the bullet locking portion 515 is set to the electric gun 10, the bullet locking portion 515 is pressed in the -x direction by the chamber 34 (see FIG. 1), and the bullet locking portion The engagement between 515 and the bullet G is released. The bullet G is thereby loaded into the electric gun 10. In FIGS. 3, 4 and 5A, the bullet locking portion 515 is in a state where the engagement with the bullet G is released.

In the present embodiment, the bullet detection device 300 is disposed in the magazine 500 and rotates in response to the detection engagement portion 301 disposed on the first follower 511 in the follower portion 510 and the detection engagement portion 301 thereof. A detection rotation unit 310 is provided.

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

When all the bullets G arranged in the magazine unit 500 have been shot, the bullets G arranged in the magazine unit 500 disappear and the magazine spring 505 is restored to a natural length sufficiently longer than the length of the bullet arrangement unit 502. Then, the first follower 511 in the follower unit 510 is pushed up toward the opening 503.

At the same time, the first follower 511 connected to the spring upper end portion 505 b of the magazine spring 505 is raised, and the detection engagement portion 301 disposed in the first follower 511 is a detection engaged portion in the detection rotation portion 310. The sensor 311 is rotated counterclockwise, and the detection push-out portion 312 integral with the detection engaged portion 311 is rotated counterclockwise so as to protrude from the inside of the magazine 500. As described above, when all the bullets G arranged in the magazine unit 500 are shot out, the detection push-out unit 312 is protruded from the inside of the magazine unit 500 to detect that the bullet G has become dark (see FIG. 4). In this case, the upper end portion 513 a of the third follower 513 protrudes from the opening 503. In the present embodiment, the position where the detection push-out portion 312 is made to project so as to protrude from the inside of the magazine portion 500 is the opposite position (in the −x direction) with respect to the bullet placement portion 502 with respect to the case 16 in the mechanical box. Yes) (see Figure 1). That is, the position of the housing 16 in the mechanical box is arranged in the direction (the + x direction) of the trigger 20 with respect to the bullet arranging portion 502. On the other hand, the detection push-out unit 312 in the bullet detection device 300 tries to detect the presence or absence of a bullet in order to cut off the switch 201 disposed outside the housing 16, so the detection push-out unit 312 is The bullet placement portion 502 is disposed at a position opposite to the position of the trigger 20 (in the −x direction).

In addition, in order to stop the function of the bullet detection device 300, the anti-collision prevention function stop device 360 is provided. This is engaged with the second detection shaft portion 350 disposed in the detection engaged portion 311 in the detection rotation portion 310 and the function stop engagement portion 361 in the anti-collision function stop device 360, and the detection rotation portion 310. The detection push-out portion 312 in the above-described embodiment is substantially retained in the magazine 500 without being protruded so much from the magazine 500. As a result, the function of the below-described anti-collision prevention device 200 can be stopped, so that even if the bullet G is removed from the bullet placement portion 502 and becomes a cullet, so-called “collision shooting” can be performed. This is particularly useful for the user who wants to experience the recoil shock only, since the operation check of the electric gun equipped with the recoil shock can be performed in a state where the bullet G is not filled in the magazine 500. is there.

That is, from the state shown in FIG. 4, the anti-collision prevention function stop device 360 is slid in the −x direction. FIGS. 5A and 5B show the state where the anti-collision prevention function stop device 360 is slid in the −x direction. In this state, the position engaging portion 365 in the anti-collision function stop device 360 is disengaged from the engagement with the first groove 551 in the magazine 500 and engages with the second groove 552. At this time, the function stop engagement portion 361 in the anti-collision function stop device 360 engages with the second detection shaft portion 350 disposed in the detection engaged portion 311 in the detection rotation portion 310. As described above, the detection rotary unit 310 is pushed down clockwise on the xy plane of FIG. 5A by the anti-collision function stop device 360, and the detection push-out unit 312 integral with the detection engaged unit 311 is the main body of the magazine. It is in the state where it remains without being protruded to the outside of the portion 501 so much.

In such a state, when the bullet G strikes, and the bullet G disappears from the bullet placement portion 502, the follower portion 510 is lifted and disposed on the first follower 511 in the follower portion 510 as described above. Although the detection engagement portion 301 engages with the detection engaged portion 311 in the detection rotation portion 310, the above-described rotation (counterclockwise rotation in FIG. 5A) in the detection rotation portion 310 is stopped with the anti-collision prevention function It is blocked by the device 360, and the detection push-out portion 312 in the detection rotation portion 310 is substantially retained in the main part 501 of the magazine in the magazine 500 without being protruded so much outside the magazine 500. In this case, the upper end portion 513a of the third follower 513 does not protrude from the opening portion 503, and the upper end portion 513a remains in the opening portion 503.

Further, from the state shown in FIGS. 5A and 5B, the anti-collision prevention function stop device 360 is slid in the + x direction. When the sliding prevention function stop device 360 is slid in the + x direction, the position engaging portion 365 in the falling protection function stop device 360 is disengaged from the second groove 552 in the magazine 500 and engages with the first groove 551. Do. At this time, the function stop engagement portion 361 in the anti-collision function stop device 360 disengages from the second detection shaft portion 350 disposed in the detection engaged portion 311 in the detection rotation portion 310. Thus, by moving the anti-collision function stop device 360, the function stop engaging portion 361 in the anti-collision function stop device 360 is arranged to be able to engage and disengage with the detection engaged portion 311 in the detection rotation portion 310. It is being done. Further, the anti-collision function stop device 360 has a groove 366. Thereby, in order for the position engaging portion 365 to elastically deform elastically, the position engaging portion 365 is preferably engaged with or disengaged from the first groove 551 and the second groove 552 (Refer FIG. 4, FIG. 5A, B).

In FIG. 5B, the second detection shaft portion 350 is configured to protrude to the front side in the drawing, and the position engagement portion 365 in the anti-collision function stop device 360 engages with the first groove portion 551 in the magazine 500. When this happens, the function of the bullet detection device 300 is not stopped, and when the second groove 552 is engaged, the function of the bullet detection device 300 is stopped (see FIGS. 4, 5A and B).

Next, the color shot preventing device 200 of the electric gun 10 will be described. As described above, the anti-collision device 200 is provided with the switch 201 on the outside of the housing 16 and, when the bullet G of the magazine unit 500 turns into a crow, in order to prevent so-called “collision shooting” Reference numeral 202 denotes a configuration in which the switch 201 is disconnected. Therefore, in response to the detection push-out portion 312 described above being protruded, the energization stop portion 202 is operated to disconnect the contact of the switch 201 (do not conduct electricity).

The energization stop unit 202 separates the contacts of the detection receiving unit 210, the piston interlocking unit 250 interlocked with the movement of the piston 30, and the switch 201 for the detection push-out unit 312 to receive an operation projecting from the magazine 500. And the switch cut-off portion 270 (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 push-out unit 312 in the -x direction. The first detection receiving unit 211 In response to the movement of the detection push-out portion 312 in the -x direction, it moves in the -x direction (see FIGS. 6, 7A, and B).

The second detection receiving portion 212 is rotatably supported by the shaft portion 213. The protruding portion 212 a of the second detection receiving portion 212 is further pressed by the tip portion 211 a of the first detection receiving portion 211 which has been pressed by the tip portion 312 a of the detection pushing 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 receiver 212 also rotates clockwise on the xz plane, and the other end 212b protrudes in the track of the recoil plate 61 that reciprocates from the -x direction to the + x direction. Do. That is, as the piston 30 reciprocates in the + x direction from the −x direction, the recoil plate 61 in the piston interlocking unit 250 interlocking with this also reciprocates in the + x direction from the −x direction. Also, as described above, the other end 212b projects into the reciprocating trajectory. That is, by being pressed by the first detection receiving portion 211 in FIGS. 8A and 8B, the second detection receiving portion 212 exhibits a so-called erected state in which the other end 212b is at the upper side in the drawing, and the other end Reference numeral 212 b projects in a reciprocation motion (−x direction and + x direction) of the recoil plate 61.

FIG. 9 is an enlarged side view of the electric gun 10 with the muzzle directed to the right in the state of FIGS. 8A and 8B. In this state, the stop plate 280 in the switch cutting portion 270 described later is in a state of not engaging 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 erected state in FIGS. 8A and 8B is subsequently recoiled in the piston interlocking portion 250 in FIGS. Engage with plate 61. As described above, since the recoil plate 61 reciprocates in the + x direction from the -x direction, the second detection receiving unit 212 engages with the recoil plate 61, and the other end of the second detection receiving unit 212 The 212 b further operates to rotate clockwise on the xz plane. That is, since the motor 22 is rotating and the piston 30 continues to reciprocate since the energization is not yet cut off, the second interlocking mechanism 250 following the reciprocation of the piston 30 receives the second detection The other end 212 b of the portion 212 further rotates clockwise on the xz plane. The spring 214 biases the second detection receiving portion 212 counterclockwise (see FIGS. 10A and 10B).

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

To explain this further, first, the switch disconnecting portion 270 includes the latch 271, the stop plate 280, and the switch lever 290. The latch spring 272 biases the latch 271 clockwise. In such a configuration, the one end 212 c of the second detection receiving portion 212 engages with the latch 271 of the switch cutting portion 270, and the one end 212 c opposes the clockwise biasing force of the latch spring 272. Is rotated counterclockwise (see FIG. 8A, FIG. 9, FIG. 10A, B and FIG. 11).

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

By the stop plate 280 moving in the −x direction, the switch lever end portion 291 of the switch lever 290 is pushed down, and the switch lever other end portion 292 is pulled up in the + y direction with the switch lever shaft portion 293 as an axis. At that time, the convex portion 294 attached to the switch lever shaft portion 293 rotates, lifts the first contact portion 201 a of the switch 201, and cuts off the contact with the second contact portion 201 b of the switch 201. As a result, the energization of the motor 22 is blocked, and it is possible to prevent blowout (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 291 and a switch lever other end 292 and has a substantially isosceles triangular shape with an obtuse apex angle which is an included angle between them. The switch lever spring 290a biases the switch lever 290 in the counterclockwise direction in FIG. Thereby, in a state where the bullet G is disposed in the magazine unit 500 or when the anti-collision function stop device 360 is functioning, the first contact portion 201 a in the switch 201 is pushed down, and the second in the switch 201 The contact with the contact portion 201b is ensured.

As described above, conventionally, it was necessary to use a mechanical box provided with a mechanical energization stop device in a dedicated electric gun. However, since the anti-collision prevention device can be installed independently of a so-called mechanical box, The existing mechanical box can be used by installing this device at a portion where there is a space regardless of the outer shape of the electric gun. Therefore, even if the user continues pulling the trigger 20 in a state where the bullet G has been shot and the bullet G in the magazine is in the blank state, an effect of preventing so-called blank shooting can be achieved. In addition, in the electric gun which does not have a magazine part, by having the same structure as a bullet detection device in the main part of the electric gun, it is possible to achieve an effect of preventing a blank shot.

In this state, the first contact portion 201a of the switch 201 is lifted by the above-described 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 broken. (See FIG. 11). Therefore, in order to bring the first contact portion 201a of the switch 201 and the second contact portion 201b into contact again, the bolt portion 295 is pulled in the + x direction. A user (not shown) pulls the bolt portion 295 and engages with the stop plate 280 through a fixed stroke. Since the stop plate 280 engaged with the bolt portion 295 is biased in the −x direction by the stop plate spring 281, the bolt portion 295 is pulled in the + x direction against this biasing force ( See Figure 12).

FIG. 13 is an enlarged bottom view of the state of FIG. 12 with the muzzle facing left. In addition, when the cartridge portion 500 filled with the bullet G 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 rests against the stop plate spring 281 at that position. The first contact portion 201a of the switch 201 is pushed down to be in 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 the present embodiment, the recoil shock generating mechanism 50 is provided, but even if this mechanism is not provided, the piston interlocking portion 250 which follows the reciprocation of the piston 30 is disposed, or It is also possible to implement piston 30 itself as piston interlocking part 250.
