Description

Empty gun prevention device in electric gun

The invention relates to a device for preventing emptying of an electric gun.

The so-called electric gun uses the rotation of the motor to drive the piston in the cylinder, and the air in the cylinder is injected by the driving force of the piston to fire bullets. The trigger is used to connect the electric switch for driving the motor.

Therefore, during the continuous pulling of the trigger, the motor continues to drive due to the continuous on-state of the electric switch. Therefore, the movement of the piston will not stop. Even if there is no bullet in the magazine, the air in the cylinder will continue to be injected, which is the so-called state of continuously emptying the gun.

Therefore, in Japanese Patent Application Laid-Open No. 2010-25501 proposed by the present applicant, a mechanical energization stop device in an electric gun is disclosed. The above-mentioned device is configured as a device for blocking the circuit of the drive portion for firing the bullet when there is no bullet on the bullet supply path communicated with the loading portion at the rear of the barrel, and stops the power supply: a bullet ejecting member, The supply path is configured to be able to move and receive force to deliver bullets to the charging part; the driven member engages with a part of the bullet ejecting member at one end and is linked to its action; the cutting member is accompanied by the driven member The movement can move from the position when the power is on to the position when it is blocked, and engage with the tappet member during the movement to the position when it is blocked, and close the switch with the movement of the tappet member; the above tappet member, There is a portion of the bullet supply port that moves backwards with the movement of the piston of the driving portion to open the bullet supply path communicated with the charging portion, and the above-mentioned cutting member is moved by a force toward the direction of closing the bullet supply port. ; And the above-mentioned switch moves by engaging with the cut-off member, so that the contact is opened, and the contact is closed by the reset operation.

However, the mechanisms such as cylinders, pistons, and gears for driving them in the above-mentioned electric guns are arranged in a predetermined frame, and these are unitized. These are referred to as gear boxes, and it is necessary to assemble the above-mentioned devices in the unitized gear boxes.

Also, since there is no space for assembling the above-mentioned devices in the known gearbox, the gearbox itself must be remanufactured. Also, depending on the type of electric gun, sometimes there is no space for assembling the above-mentioned device in the gear box even if it is to be remanufactured, so it is not realistic to apply the above-mentioned mechanical energization stop device to all gear boxes.

The electric gun of the fourth viewpoint is provided with the empty gun prevention device of the first viewpoint to the third viewpoint.

[Advantages of the Invention] According to the present invention, it is possible to provide an empty gun preventing device which can stop the rotation of the motor when the ammunition is exhausted without changing the conventional gear box.

The electric gun 10 with the empty gun preventing device 200 in this embodiment will be described. The electric gun 10 is outside the frame body 16 in the gear box described later. In addition to the first contact 21 that contacts and energizes when the trigger 20 described later is pulled, a switch 201 is additionally provided. When the bullets G in the magazine part 500 are exhausted , in order to prevent the so-called empty gun, the energization stop part 202 is configured, and the energization stop part 202 cuts off the switch 201 (see FIG. 1 and FIG. 2 ).

The first contact 21 and the switch 201 are connected in series through the wiring S. When the first contacts 21 and the switch 201 are both energized, the bullet G is fired. When the bullet G is exhausted, the energization stop part 202 can prevent emptying the gun (see FIGS. 1 and 2 ) by either or both of energizing the switch 201 or restoring the pulled trigger 20 to its original state.

First, the structure of the mechanism part 15 for firing the bullet G in the electric gun 10 will be described. The mechanism part 15 is arranged in the frame body 16 . And mechanism part 15 has trigger 20, first contact 21, motor 22, motor gear 23 and helical gear 24, gear 25 and sector gear 26, piston 30, the rack part 31 that this piston 30 has, the rack part 31 that this piston 30 has, the piston 30 The spring 32 exerts force in the -X direction. Here, the frame body 16 having the mechanical part 15 may be referred to as a gear box.

When a user (not shown) pulls the trigger 20, the first contact point 21 contacts, and the electric power from the battery 100 flows into the motor 22, whereby the motor 22 rotates. By this rotation, the motor gear 23 disposed on the output shaft of the motor 22 rotates, the helical gear 24 meshed with the motor gear 23 rotates, the gear 25 meshed with the helical gear 24 rotates, and the gear 25 meshes with the gear 25. The meshed sector gears 26 rotate.

The sector gear 26 meshes with the rack portion 31 of the piston 30, whereby the piston 30 moves in the +X direction. Consequently, the piston 30 compresses the spring 32 .

The sector gear 26 has a toothless part that does not have gear teeth locally. Therefore, if the toothless part of the sector gear 26 is rotated to a position opposite to the rack part 31, the engagement between the rack part 31 and the sector gear 26 Release, by the force of the spring 32 to restore the natural length, the piston 30 arranged in the cylinder 40 moves rapidly to the -X direction, and the air in the cylinder 40 is sprayed on the bullet G pre-arranged at the front end of the nozzle 33, thereby using the air to fire the bullet G.

In addition, the electric gun 10 is equipped with a recoil impact generating mechanism 50 to generate a so-called recoil impact for virtually reproducing the impact generated in a real gun due to the reaction of a bullet fired. Therefore, this will also be described. The recoil impact generating mechanism 50 has a piston engaging portion 51 in the piston 30 and a recoil counterweight 52 engaged with the piston engaging portion 51 , and the recoil counterweight 52 is stressed in the −X direction by a recoil spring 53 . In addition, the recoil weight 52 preferably has a predetermined mass so as to virtually reproduce the impact.

As described above, the piston 30 arranged in the air cylinder 40 rapidly moves in the -X direction, and the air in the air cylinder 40 is sprayed on the bullet G previously arranged at the front end of the nozzle 33, thereby firing the bullet G with the air. At this time, the piston engaging portion 51 in the piston 30 and the recoil counterweight 52 engaged with the piston engaging portion 51 are rapidly moved to - When moving in the X direction, the recoil weight 52 collides with the front end portion 54 to generate a shock, and a so-called recoil shock is obtained.

Thereafter, as the piston 30 moves in the +X direction again, the recoil counterweight 52 engaged with the piston engaging portion 51 in the piston 30 also moves in the +X direction, and accumulates pressure in the recoil spring 53 .

Thereafter, the piston 30 arranged in the cylinder 40 moves in the -X direction again in the same manner as above, and the recoil impact is obtained again by the force of restoring the natural length by the stored recoil spring 53 . In this way, when the trigger 20 is pulled, every time the bullet G is fired, a so-called recoil impact is obtained. In addition, it has a recoil bar 60 connected to the recoil weight 52 . Furthermore, the electric gun 10 has the recoil weight 52, the recoil rod 60, and the recoil plate 61 connected to the recoil rod 60, and the recoil weight 52, the recoil rod 60, and the recoil plate 61 are sometimes referred to as the piston interlocking portion 250. . The piston interlocking part 250 is interlocked with the operation of the piston 30 as described in the text, and reciprocates in the -X direction and the +X direction corresponding to the firing of the bullet G.

As mentioned above, the blown gun prevention device 200 in the present embodiment has, in addition to the first contact 21 outside the frame body 16 in the gear box, additionally have a connection with the first contact 21 through the wiring S. The switch 201 connected in series, the bullet detection device 300 detects that the bullet G is exhausted and the bullet G in the magazine part 500 is exhausted, and the switch 201 is cut off by the switch cut-off part 270 in the energization stop part 202, thereby blocking The energization of the motor 22 is cut off by the piston interlocking part 250 driven by the movement of the piston 30 by the switch cut-off part 270 . Thus, 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 cut off, thereby preventing the gun from blowing out.

Then, the bullet detection device 300 which detects that there is no bullet G in the magazine unit 500 will be described. The bullet detection device 300 is disposed on the magazine unit 500 . Here, first, the structure of the magazine unit 500 will be described, and further, the bullet detection device 300 will be described.

The magazine unit 500 has a magazine body unit 501 that constitutes what is called an outer contour of a magazine that supplies bullets G to the electric gun 10 . Also, the bullet arrangement portion 502 is a passage for arranging a plurality of bullets G and sending the bullets G into the electric gun 10, and the width of the bullet arrangement portion 502 is set according to the width of the bullet G. The bullet arrangement portion 502 includes a magazine spring 505 for pushing up the plurality of bullets G in the direction of the opening 503 (+Y direction), and a follower 510 biased by the magazine spring 505 .

Thus, the follower 510 has a first follower 511 biased by the magazine spring 505, a second follower 512 biased by the first follower 511, and a second follower 512 biased by the second follower 512. As for the third follower 513, as described above, the bullet G always receives force in the direction of the opening 503 (+Y direction). That is, the magazine spring 505 presses the first follower 511 in the follower 510 . Also, either 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 connected in a bendable manner so that the bullet placement portion 502 is assumed to be in a curved shape so that the curved shape can be followed. Also, the third follower 513 is in contact with the second follower 512 , thereby being pressed by the second follower 512 .

In addition, the lower end portion 505 a of the magazine spring 505 is disposed on the end portion 502 a of the bullet arrangement portion 502 , and the spring upper end portion 505 b of the magazine spring 505 is connected to the first follower 511 of the follower portion 510 . In addition, when the magazine unit 500 is detached from the electric gun 10 (not shown), in order to prevent the bullet G from flying out, a bullet locking portion 515 is provided, and the bullet locking spring 516 is biased in the +X direction.

That is to say, if a plurality of bullets G are filled in the magazine portion 500 of the above-mentioned configuration, the magazine spring 505 is compressed by the plurality of bullets G, and the bullet catches in the +X direction by the bullet locking spring 516. The stop portion 515 prevents the bullet G arranged at the top of the plurality of bullets G from flying out, and the plurality of bullets G are arranged in the magazine portion 500 . Also, when the magazine 500 is placed in the electric gun 10, the bullet locking portion 515 is pushed in the −X direction by the chamber 34 (see FIG. 1 ), and the bullet locking portion 515 is engaged with the bullet G. lifted. Thereby, the bullet G is loaded into the electric gun 10 . In addition, in FIG. 3 , FIG. 4 , and FIG. 5A , the bullet locking portion 515 is in a state where the engagement with the bullet G is released.

In this embodiment, the bullet detection device 300 is arranged in the magazine part 500, and has: the detection engagement part 301, the first follower 511 arranged in the follower part 510; and the detection rotation part 310, with the detection The engagement part 301 is raised and rotated.

The detection rotation part 310 has a detection engaged part 311, a detection ejection part 312 arranged at an angle of approximately 90 degrees to the detection engagement part 311, a detection shaft part 313, and a detection ejection part 312 arranged between the detection ejection part 312 and the detection shaft part 313. A thin plate-shaped and triangular-shaped first body portion 330 between the shaft portions 313 . The detection engaged part 311 , the detection ejection part 312 , the detection shaft part 313 , and the first body part 330 are integrated, and these constitute the detection rotation part 310 . Moreover, the detection rotation part 310 rotates so that it may swing around the detection shaft part 313 (refer FIG. 3).

If all the bullets G arranged in the magazine part 500 are shot out, then the bullets G arranged in the magazine part 500 will be exhausted, and the magazine spring 505 will return to a natural length that is long enough than the length of the bullet arrangement part 502, so that it can move toward the opening. Push up the first follower 511 in the follower 510 in the direction of the follower 503 .

At the same time, the first follower 511 connected to the spring upper end 505b of the magazine spring 505 rises, and the detection engagement part 301 arranged on the first follower 511 makes the detection engaged part in the detection rotation part 310 311 rotates in the counterclockwise direction, so that the detection ejection part 312 integrated with the detection engaged part 311 rotates in the counterclockwise direction, so that it protrudes in a manner of flying out of the magazine part 500 . In this way, when all the bullets G arranged in the magazine part 500 are ejected, the depletion of the bullets G is detected by making the detection ejection part 312 protrude from the magazine part 500 (see FIG. 4 ). In this case, the upper end portion 513 a of the third follower 513 protrudes from the opening portion 503 . In this embodiment, the position where the detection ejection portion 312 protrudes in such a way as to fly out of the magazine portion 500 is in a position opposite to the frame body 16 in the gear box (in the -X direction) relative to the bullet arrangement portion 502 ( See Figure 1). That is, the position of the frame body 16 in the gear box is arranged in the direction of the trigger 20 (in the +X direction) with respect to the bullet arrangement portion 502 . On the other hand, the detection ejection part 312 in the bullet detection device 300 is to detect the presence or absence of a bullet in order to cut off the switch 201 arranged outside the frame body 16, so the detection ejection part 312 is opposite to the bullet arrangement part 502. And it is arranged in 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, a blanking gun prevention function stopping device 360 is provided. It engages the second detection shaft part 350 arranged on the detection engaged part 311 of the detection rotating part 310 with the function stop engaging part 361 of the emptying gun preventing function stopping device 360, so that the detection rotating part does not The detection ejection part 312 in 310 protrudes too much to the outside of the magazine part 500 , and basically remains in the magazine part 500 . Thereby, the function of the emptying gun preventing device 200 described later can be stopped, so even in the state where the bullets G are exhausted from the bullet arrangement portion 502 , so-called emptying can be performed. In particular, when the bullet G is not filled into the magazine part 500, it is possible to confirm the action of the electric gun with the recoil impact, so this is not only helpful for safety, but also suitable for users who only want to experience the recoil impact.

That is, from the state shown in FIG. 4 , the emptying gun preventing function stop device 360 is slid to move in the -X direction. Figure 5A and Figure 5B show the state where the empty gun preventing function stopping device 360 is slid in the -X direction. In this state, the position engaging portion 365 of the emptying gun preventing function stopping device 360 is disengaged 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 engagement part 361 of the empty gun prevention function stop device 360 is engaged with the second detection shaft part 350 disposed on the detection engaged part 311 of the detection rotation part 310 . As mentioned above, the detection rotating part 310 is pressed down clockwise on the XY plane in FIG. The exit portion 312 protrudes too much to the outside of the magazine body portion 501 and remains in a state.

In this state, when the bullet G is shot out, and the bullet G is exhausted from the bullet arrangement part 502, as described above, the follower part 510 rises and is arranged on the first follower 511 of the follower part 510. The detection engaging part 301 of the detection rotating part 310 is engaged with the detection engaging part 311, but the above-mentioned rotation (rotation in the counterclockwise direction in FIG. 5A) in the detection rotating part 310 is blocked by the empty gun prevention function stop device 360 prevents the detection ejection part 312 in the detection rotating part 310 from protruding too much to the outside of the magazine part 500, and basically remains in the magazine body part 501 in the magazine part 500. In this case, the upper end portion 513 a of the third follower 513 does not protrude from the opening portion 503 , and the upper end portion 513 a remains in the opening portion 503 .

In addition, from the state of FIG. 5A and FIG. 5B , the device 360 for stopping the empty gun preventing function is slid to move in the +X direction. If the empty gun preventing function stopping device 360 is slid in the +X direction, the position engaging part 365 in the emptying gun preventing function stopping device 360 will come out from the second groove part 552 in the magazine part 500 and come out of the first groove part 552. The groove portion 551 is engaged. At this time, the function stop engagement part 361 of the emptying gun prevention function stop device 360 is out of engagement with the second detection shaft part 350 disposed on the detection engaged part 311 of the detection rotation part 310 . In this way, by moving the empty gun preventing function stopping device 360 , the function stopping engaging part 361 in the emptying gun preventing function stopping device 360 is arranged so as to be disengageable from the detection engaged part 311 in the detecting rotating part 310 . In addition, the emptying gun preventing function stopping device 360 has a groove portion 366 . Thereby, since the position engaging portion 365 is elastically deformed in a recoverable manner, the position engaging portion 365 is suitable for engaging with the first groove portion 551 and the second groove portion 552 or disengaging from them (see FIG. 4, Figure 5A, Figure 5B).

In addition, in FIG. 5B , the second detection shaft portion 350 is configured to protrude toward the front side of the drawing, and the position engagement portion 365 in the empty gun prevention function stop device 360 is engaged with the first groove portion 551 in the magazine portion 500. When it is engaged, the function of the bullet detection device 300 will not be stopped, and when it is engaged with the second groove portion 552, the function of the bullet detection device 300 will be stopped (see FIG. 4 , FIG. 5A , and FIG. 5B ).

Next, the empty gun preventing device 200 in the electric gun 10 will be described. The empty gun preventing device 200 is constituted as follows: as mentioned above, a switch 201 is provided outside the frame body 16. When the bullets G in the magazine section 500 are exhausted, in order to prevent the so-called empty gun, the energization stop part 202 described later cuts off the bullet G. Switch 201 contacts. Therefore, it is configured such that the contact of the switch 201 is cut off (the current is not energized) by actuating the energization stopping portion 202 in response to the above-mentioned detection of protrusion of the ejection portion 312 .

The energization stopping part 202 has a detection receiving part 210 for receiving and detecting the movement of the ejector part 312 protruding from the magazine part 500, a piston interlocking part 250 linked with the action of the piston 30, and a switch for separating the contacts of the switch 201. The cutting part 270 (refer to FIG. 6 ). The detection receiving part 210 has the first detection receiving part 211 and the second detection receiving part 212, and receives and detects that the ejector part 312 moves to the -X direction. Those who move in the -X direction by moving in the -X direction (see Figure 6, Figure 7A, and Figure 7B).

The second detection receiver 212 is rotatably fixed by a shaft 213 . The protruding portion 212 a of the second detection receiving portion 212 is further pressed by the front end portion 211 a of the first detection receiving portion 211 pushed by the front end portion 312 a of the detection ejection portion 312 . According to FIG. 8A and FIG. 8B which are bottom views, the second detection receiving part 212 rotates clockwise on the XZ plane. Thereby, the other end portion 212b of the second detection receiving portion 212 also rotates clockwise on the XZ plane, whereby the other end portion 212b reciprocates from the -X direction to the +X direction and then the seat force plate 61 prominent on the track. That is, the piston 30 reciprocates from the −X direction to the +X direction, and the recoil plate 61 in the piston interlocking portion 250 associated therewith also reciprocates from the −X direction to the +X direction. Moreover, as mentioned above, the said other end part 212b protrudes on this reciprocating orbit. That is, in FIG. 8A and FIG. 8B, the second detection receiving part 212 is pushed by the first detection receiving part 211 so that the other end 212b faces upward in the drawing so-called upright state, and the other end 212b is in the recoil force. The reciprocating motion (-X direction and +X direction) of the plate 61 is projected on the track.

FIG. 9 is an enlarged side view of the state in which the muzzle of the electric gun 10 faces rightward in the state of FIGS. 8A and 8B . In this state, the shutter 280 in the switch blocking portion 270 described later is not engaged with the switch lever 290 .

In this state, the piston 30 is still reciprocating, so the other end 212b of the second detection receiving part 212 in the upright state in Figs. The recoil plate 61 is engaged. As mentioned above, the recoil plate 61 reciprocates from the −X direction to the +X direction, therefore, the second detection receiving portion 212 is engaged with the recoil plate 61, and the other end portion 212b of the second detection receiving portion 212 is further positioned on the XZ plane. Work in a clockwise rotation. That is, since the energization has not been cut off, the motor 22 rotates and the piston 30 continues to reciprocate. The other end portion 212b further rotates clockwise on the XZ plane. In addition, the spring 214 biases the second detection receiver 212 in the counterclockwise direction (see FIGS. 10A and 10B ).

Thereby, one end portion 212c of the second detection receiving portion 212 also further rotates clockwise on the XZ plane. Furthermore, one end portion 212c of the second detection receiving portion 212 in the detection receiving portion 210 rotated clockwise is engaged with the switch blocking portion 270 to operate the switch blocking portion 270 . Also, by the operation of the switch disconnection unit 270, the switch disconnection unit 270 disconnects the contact of the switch 201, that is, the switch 201 is disconnected (see FIG. 8A, FIG. 9, FIG. 10A, and FIG. 10B).

Further explaining this, first, the switch blocking unit 270 has a latch 271 , a shutter 280 , and a switch lever 290 . Also, the latch spring 272 biases the latch 271 clockwise. With this structure, one end 212c of the second detection receiving part 212 engages with the latch 271 in the switch cut-off part 270, and the one end 212c counteracts the clockwise force of the latch spring 272, so that The latch 271 rotates counterclockwise (see FIGS. 8A , 9 , 10A, 10B, and 11 ).

The latch 271 has a latch protrusion 271 a, and the shutter 280 engaged with the latch protrusion 271 a is biased in the −X direction by the shutter spring 281 . Therefore, when the latch 271 is rotated counterclockwise, the shutter 280 disengaged from the latch protrusion 271 a of the latch 271 moves in the −X direction. Fig. 11 is a side view of the state in which the muzzle of the electric gun 10 faces rightward in the state of Figs. 10A and 10B. By comparing FIG. 9 and FIG. 11 , it can be understood that the baffle plate 280 moves in the −X direction.

One end 291 of the switch lever 290 is pushed down by the movement of the baffle plate 280 in the -X direction, and the other end 292 of the switch lever is lifted in the +Y direction with the switch lever shaft 293 as the axis. At this time, the convex portion 294 mounted on 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 . Thereby, energization to the motor 22 is blocked, and emptying of the gun can be prevented (refer to FIG. 11 ). That is, the detection receiving unit 210 activates the switch disconnection unit 270 , and the switch disconnection unit 270 disconnects the switch 201 . In addition, the switch lever 290 has a switch lever one end 291 and a switch lever other end 292, and has a substantially equilateral triangle shape in which the included angle, that is, the apex angle is an obtuse angle. In addition, the switch lever spring 290a biases the switch lever 290 counterclockwise in FIG. 11 . Thereby, under the condition that the bullet G is arranged in the magazine part 500, or under the condition that the emptying gun preventing function stopping device 360 is functioning, the first contact part 201a in the switch 201 is pressed down, and the switch 201 is turned ON. Among them, the second contact portion 201b is in reliable contact.

In this way, conventionally, it was necessary to use a gear box equipped with a mechanical energization stop device in a dedicated electric gun. However, since the so-called gear box can be provided with an empty gun prevention device independently, it can be used in places where there is space regardless of the shape of the electric gun. This device is partially provided, so that an existing gearbox can be used. Therefore, even if the user continues to pull the trigger 20 when the bullets G are fired and the bullets G in the magazine are exhausted, the effect of preventing the so-called emptying of the gun can be exerted. In addition, in an electric gun without a magazine section, by having the same structure as the bullet detection device on the body of the electric gun, the effect of preventing the gun from emptying can be exerted.

In addition, in this state, the first contact part 201a in the switch 201 is lifted by the above-mentioned functions of the baffle plate 280 and the switch lever 290, and the contact with the second contact part 201b in the switch 201 is cut off. (See Figure 11). Therefore, in order to bring the first contact portion 201 a and the second contact portion 201 b into contact again in the switch 201 , the plug portion 295 is pulled in the +X direction. A user (not shown) pulls the plug portion 295 , and the plug portion 295 engages with the baffle plate 280 after a certain stroke. The baffle 280 engaged with the plug portion 295 is urged in the −X direction by the baffle spring 281 , and thus pulls the plug portion 295 in the +X direction against the force (see FIG. 12 ).

Fig. 13 is an enlarged bottom view of the state in which the muzzle is facing left in the state of Fig. 12 . In addition, if the magazine portion 500 pre-filled with bullets G is arranged in the electric gun 10, as described above, the bolt 295 is pulled in the +X direction, the shutter 280 also moves in the +X direction, and engages with the latch 271 again.
