JP4745011B2 - Device for controlling the number of firings in an electric gun - Google Patents

Description

  The present invention relates to an electric gun in which the device is driven by a sector gear meshing with a rack provided in a movable part of a piston cylinder device, and the switching gun controls the energization of a motor that drives the sector gear. It is related with the apparatus which controls.

  For example, as disclosed in Japanese Patent Laid-Open No. 3-221793, there is a gun commonly called an electric air gun, which drives a piston of a piston cylinder device by a motor-driven gear to generate compressed air, and Is a method to fire. With such an air gun, bullets will continue to be fired during the trigger operation, which means that they will be shot out quickly. Therefore, it is attempted to control so that only a preset number of bullets are fired even if the trigger is continuously pulled.

  However, those equipped with a conventional control system use a drive circuit and timer using FETs (field effect transistors), which raises the problem of increasing the cost of the gun. When using the timer, depending on the state of the battery, even if the time setting is the same, there may occur a situation in which four shots occur or only two shots remain.

  On the other hand, among the inventions and devices that have been filed, there are, for example, those disclosed in Japanese Utility Model Publication No. 6-30695, and the device detects the current that flows when a trigger is pulled in an electric air gun or an electric toy gun, We have proposed a device that can be fired (burst) with an arbitrary number of points at the time of launch by controlling the current flow time. However, this device is such that the energization is stopped when the finger is released from the trigger and the switch is opened, and does not suggest any further matters, and does not have a configuration for limiting the continuous fire.

Japanese Patent Laid-Open No. 3-221793 Japanese Utility Model Publication No. 6-30695

  The present invention has been made paying attention to the above-mentioned points, and an object thereof is to make it possible to accurately control the number of continuous firings, that is, the number of firings, in an electric gun. Another object of the present invention is to realize control of the number of continuous firings without causing an increase in cost.

In order to solve the above-described problems, the present invention drives the above-described device by a sector gear meshing with a rack provided in a movable portion of the piston cylinder device, and controls the energization to the motor that drives the sector gear by the switching portion. In an electric gun, a switch contact configured with a switch contact, an operation element for opening and closing the switch , and a switch contact, and a counter lever capable of moving a required amount in the front-rear direction of the main body by engagement with a rotating portion that rotates together with the sector gear; The switch contacts can be turned on by engagement with the switching unit, and the counter stopper urged by the elastic body in the direction to turn off the switch contact, and between the counter lever and the counter stopper are almost the same. Can move in parallel directions and contact with them And a counter having one engaging portion engageable with the counter lever and the other engaging portion engageable with the counter stopper, the position of the one engaging portion being a counter The counter lever moves with the movement of the rotating part that rotates together with the sector gear and performs the firing operation, moves the counter that engages with one of the engaging parts, and the counter stopper on the other engaging part Is engaged to perform a firing operation, and the switching unit is configured to be turned off when the counter stopper is not engaged with the other engagement unit.

  In the present invention, the piston cylinder device generates compressed air. However, in the piston cylinder device, the piston is usually a movable part that reciprocates, but the piston can be fixed and the cylinder can be reciprocated. It is. In the present invention, either the piston or the cylinder can be used as the movable part, and therefore the movable part of the piston cylinder device may be either the piston or the cylinder.

  The movable part is provided with a rack along the reciprocating direction, and the movable part of the piston cylinder device is driven by a sector gear meshing with the rack. The sector gear has a toothed part that meshes with the rack to drive the movable part, and after driving the movable part to the limit position in the forward direction, the toothless part that is brought into an unengaged state for rapid compression operation have. In order to generate compressed air by a reciprocating operation, the movable portion takes a configuration in which an urging member such as a coil spring is accumulated against the urging force by meshing the sector gear and the rack in the forward operation, Moreover, it is convenient to perform the compression operation by the urging force of the urging member in the backward operation.

  The switching unit is means for controlling energization to the motor. In order to control the supply of electric power to the motor, a switch contact and an operator for opening and closing the contact are provided. In addition, it is possible to take a method of opening and closing the switch contact by moving the connecting member in response to an operation by the operation element. As described above, the switching unit is composed of, for example, three portions of a trigger as a manipulator, a trigger, a connecting member, and a switch contact. In this switching unit, when the trigger is pulled, the switch contact is turned on via the connecting member, and when the trigger is stopped, the switch contact is turned off.

  Therefore, in the electric gun that is the subject of the present invention, when the switching unit is operated, the motor is started, and the movable unit provided with the rack that meshes with the toothed unit performs the forward operation as the sector gear rotates. Is driven to the limit position for forward movement. During this drive, pressure is accumulated in the urging member, and with the release of the accumulated pressure, air is compressed between the movable part and the fixed part by the backward movement of the movable part, and compressed air is generated. Can be ejected from the ejection nozzle on the fixed part side. However, it is possible to generate compressed air by the reciprocating motion of the movable part without using an urging member, and such a thing is also an object of the present invention.

  In such an electric gun, a counter stopper, a counter lever, and a counter are interposed between a switching unit and a sector gear to control the number of continuous firings (the number of shots). The number of continuous firings targeted by the present invention is the number of firing operations performed by a single trigger operation, and as already mentioned in part, it is also referred to as firing or ○ point bursting, for example, 2 or 3 times less. Any number of times. If a bullet is loaded, continuous firing such as 2 shots and 3 shots is performed for each trigger operation, and then stopped after 2 shots, 3 shots, and so on.

  The counter lever is movable by a required amount (distance) by engaging with a rotating portion that rotates together with the sector gear. The counter stopper is engageable with a member of the switching unit, and is provided to be movable by a required amount (distance) by the operation of the member of the switching unit. The counter is disposed between the counter stopper and the counter cover, and is provided so as to be movable and positionally adjustable in a direction substantially parallel to them.

  As described above, the switching unit is a means for controlling energization to the motor, and the counter position is set by the counter stopper and the counter lever interposed between the switching unit and the motor-driven sector gear. The number of firings (the number of shots) is controlled by the number of engaging protrusions provided on the counter. The counter is provided with two types of engaging portions, one engaging portion that can be engaged with the counter lever and the other engaging portion that can be engaged with the counter stopper, each having a plurality of engaging recesses. The counter lever is moved to the required distance backward by the rotating part that rotates together with the sector gear, and the counter that engages with the other engaging part is retracted. The position where the counter stopper is engaged is shifted backward, and the switching unit is turned off when the counter stopper is not engaged.

  The counter lever must move back a predetermined distance each time the rotating part rotates and then return to the front position until the next rearward movement. Therefore, the counter lever is always urged forward with an arbitrary force. It is desirable that Further, since the counter is also retracted by one of the engaging portions, it is desirable that the counter is always urged forward by an arbitrary force in order to counter the force in the retracting direction. In addition, since the switch contact is turned on when the trigger is pulled and turned off when the trigger is stopped, it is desirable that the member having the switch contact is biased by the biasing member in this case as well.

  Since the present invention is configured and operates as described above, in the so-called electric gun, the number of continuous firing or the number of continuous firing bullets can be accurately controlled, and in particular, the energization is controlled by the switching unit, The counter position is adjusted by the counter stopper and the counter lever, and the number of continuous shots or the number of continuous bullets is controlled mechanically, so accurate firing (burst) is possible regardless of the battery capacity. There is a remarkable effect that there is no problem of cost increase due to electrical control.

  Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. FIG. 1 is an explanatory side view of an electric gun to which the present invention is applied, FIG. 2 shows the whole firing frequency control apparatus according to the present invention, A is a side view, and B is a front view.

  In the figure, reference numeral 11 denotes a piston cylinder device. In the illustrated example, the cylinder 12 is fixed, and the piston 13 is an orthodox type having a movable portion. A nozzle 14 is provided at the front of the cylinder, and compressed air is used. It is the structure which injects. The bullet B is supplied to the loading unit 15 set immediately before the nozzle 14 and is fired by the injection of compressed air generated by releasing the accumulated pressure of the urging member 16 accumulated by the retraction of the piston 13. The bullet B is supplied to the loading unit 15 by the nozzle unit 14 temporarily retracting in conjunction with the firing operation.

  The piston 13 which is a movable part of the piston cylinder device 11 is provided with a rack 17 along the direction of movement. A sector gear 20 which meshes with the rack 17 is formed in the main body near the rear end of the piston protruding from the cylinder 12. It is pivotally supported. The sector gear 20 has a toothed portion 18 having a tooth row that meshes with the rack 17 and a toothless portion 19 for rapidly compressing the piston 13 so as not to mesh with the rack 17. By the drive, the reverse drive of the piston 13 to the limit position in the forward direction by one rotation and the generation of compressed air by the backward operation of the urging member 16 that has accumulated pressure are performed. The sector gear 20 has a rotating portion 21 that rotates together with the sector gear 20, and engages and drives a counter lever 33 described later.

A switching unit 22 is provided for controlling the energization of the motor. The illustrated example is for switching the switch contacts 23 and 24 and opening and closing the switch contacts 23 and 24 in order to control the supply of electric power to the motor. The operation member 25 includes a trigger, a trigger, and a communication member 26 that connects the switch contacts 23 and 24 to the operation member 25. The switch contacts 23 and 24 are provided so as to be able to engage with the free end of the connecting member 26 pivotally supported on the main body together with the trigger, and when the contact is pushed up by the engagement, one contact 23 moves while the other contact It has a self-cleaning function that keeps a good conducting contact state by sliding 24. The connecting member 26 is urged by an elastic body 27 in the direction of pushing back the trigger around the shaft support portion, and the switch contacts 23 and 24 are also urged by the elastic body 28 in the direction of opening the contact. Similar to the elastic body 27 of the connecting member 26, the force acts on the moving contact side 23 in the direction away from the fixed contact point 24, that is , in the clockwise direction in FIG. One contact 23 is pivotally supported by a long hole 29a provided on the other fixed contact 24 side, so that it can move up and down and rotate backward from the vertical position. Reference numeral 29b denotes a support shaft, and reference numeral 31 denotes an engagement element, which can be engaged with a mating engagement element 32 of a counter 30 described later.

  Between the sector gear 20 and the switching unit 22, the counter 30, a counter lever 33 and a counter stopper 34 for controlling the counter 30 are provided. The counter 30 is located between the sector gear 20 and the switching portion connecting member 26, and can be moved in the front-rear direction at the front portion thereof and can be rotated up and down by the support shaft 36 to the long hole 35 on the main body side. It is attached. The counter 30 has one engaging portion 37 that can be engaged with the counter lever 33 and the other engaging portion 38 that can be engaged with the counter stopper 34. The one engaging portion 37 is equidistant. For example, three engaging recesses A, B, and C, and the other engaging portion 38 has similar engaging recesses D, E, and F, but one engagement The positions of the concave portions of the portion 37 and the other engaging portion 38 are shifted by a half of the interval between the concave portions and are arranged in the front-rear direction. The engaging portion 32 is provided at the front portion of the counter 30 and is urged by an elastic body 39 forward of the counter itself.

  The counter lever 33 has a protrusion 40 that engages with one of the engaging portions 37 of the counter 30. The counter lever 33 can be moved in the front-rear direction by the support shaft 42 in the elongated hole 41 on the upper side of the main body and can be rotated up and down. A required amount (distance) can be moved backward by engagement with a rotating portion 21 that rotates together with the sector gear 20. The counter lever 33 is biased in the return direction by the elastic body 39 '(see FIG. 17). The counter stopper 34 is pivotally supported by a support shaft 43 at a lower portion on the main body side at a position substantially the same height and forward as the connecting member 26, and is a protrusion that engages with the other engagement portion 38 of the counter 30. The projection 44 is biased by the elastic body 45 in a direction away from the counter 30. The counter stopper 34 has a mating projection 47 that can be engaged with an intermediate projection 46 provided on the connecting member 26. Further, a tip engaging portion 48 is provided at the tip of the connecting member 26 so that the switch contact portion can be pushed up by engaging with the mating engaging portion 49 on the switch contact side.

  The long hole 35 to which the counter 30 is attached is formed to be longer than the length of the engaging portions 37 and 38. When the counter hole 30 is moved forward, the counter 30 is not operated by the counter stopper 34, and the rearmost hole When the counter 30 is moved, the mating engagement portion 32 of the counter 30 is not engaged with the engagement element 31 on the switch contact side. The trigger, which is the operating element 25, can contact the connecting member 26 at the end points 25a and 26a, and receives a biasing force in the return direction.

  Next, the operation of the firing number control apparatus 10 of the present invention configured as described above will be described. FIG. 3 to FIG. 14 are examples of controlling the number of continuous shots to three shots, which are called three-point shots or three-point bursts. The state in which nothing is operated on the electric gun G of the present invention is shown in FIG. 1, and when the firing operation is performed by pulling the trigger, the state shown in FIG. 3 is obtained.

  That is, when the operating element 25 is operated, an operating force is transmitted at the end points 25a and 26a, the connecting member 26 is rotated counterclockwise, and the intermediate protrusion 46 of the connecting member 26 contacts the counterpart protrusion 47. Thus, the counter stopper 34 is rotated clockwise, and the protrusion 44 at the tip of the counter stopper pushes up the counter 30 in contact with the engagement recess D at the rearmost part and rotates it clockwise. At this time, in one engagement portion 37 of the counter 30, the projection 40 at the tip of the counter lever 33 is engaged with the first engagement recess A, and the tip engagement portion 48 of the connecting member 26 is switched to the switching portion. Since the movable switch contact 23 is pushed up in contact with the mating engagement portion 49 of 22 and slidably contacted with the contact 24, an energized state is established (FIG. 4A, B).

  When the motor is started and the sector gear 20 starts to rotate, the toothed portion 18 meshes with the rack 17 of the piston cylinder device 11 to retract the piston 13, and accordingly, the biasing member 16 is in a pressure accumulation state (FIG. 5). . Immediately before the sector gear 20 tries to disengage the toothed portion 18 from the rack 17, the rotating portion 21 on the sector gear side engages with the engagement end 33 a of the counter lever 33 to retract the counter lever 33. It will be. Accordingly, the protrusion 40 at the tip of the counter lever 33 retracts the counter 30 meshing with the engagement recess A of the one engagement portion 37, and in the process, the counter located in the engagement recess D of the other engagement portion 38 The protrusion 44 at the tip of the stopper 34 moves over the mountain and moves to the next engagement recess E, and stops the movement of the counter 30. As a result, the counter 30 has moved one mountain from the engagement recess D to E.

  During this time, the sector gear 20 rotates from the toothed portion 18 to the toothless portion 19 and the urging member 16 that was in a pressure accumulation state is released all at once, so that compressed air is generated by the piston 13 and ejected from the nozzle, The first bullet B can be fired. The piston 13 is advanced by the toothless portion 19 of the sector gear 20, and the counter lever 33 is released from the rotating portion 21, and until the next time the toothed portion 18 meshes with the rack 17, an urging force (not shown) is applied. It advances by means and returns to a fixed position, and meshes with the second engaging recess B of the counter 30 (FIG. 6).

When the sector gear 20 further rotates and the second rotation starts, the piston 13 moves backward due to the engagement between the toothed portion 18 and the rack 17, and the pressure accumulation of the biasing member 16 proceeds. Immediately before starting to move forward, the rotating portion 21 again engages with the engaging end 33a of the counter lever 33 to retract the counter lever 33 by one mountain, and the protrusion 40 at the tip of the counter lever 33 is in one engagement. The counter 30 is retracted while meshing with the engagement recess B of the joint portion 37, and in the process, the protrusion 44 of the counter stopper 34 in the engagement recess E of the other engagement portion 38 gets over one mountain and the next Move to the recess F and stop the movement of the counter 30. This is the state immediately after FIG. When the sector gear 20 rotates from the toothed portion 18 to the toothless portion 19, the piston 13 advances at a stroke by the biasing member 16 that has been in a pressure accumulation state, and compressed air is generated, and the second bullet is fired. Will get. After the second shot is fired, the counter lever 33 is released from the rotating portion 21, and then is advanced by an urging means (not shown) until the toothed portion 18 meshes with the rack 17, and returns to a fixed position. meshes with the third engaging recess C of the counter 30 (FIG. 8).

  Further, when the sector gear 20 enters the third rotation, the piston 13 moves backward as the toothed portion 18 and the rack 17 mesh with each other, and the pressure accumulation of the urging member 16 proceeds, and further, the toothless portion 19 immediately before the piston 13 starts moving forward, the rotating portion 21 enters the third engagement with the counter lever 33, and the counter lever 33 is retracted by one mountain along the long hole 35, so The counter 30 is retracted in a state where the portion 40 is engaged with the concave portion C of the one engaging portion 37 (FIG. 9). In the process, the protrusion 44 of the counter stopper 34 that was in the recess F of the other engagement portion 38 moves further than the recess, while the sector gear 20 rotates from the toothed portion 18 to the toothless portion 19, The accumulated force of the urging member 16 in the accumulated state is released, the piston 13 advances at a stretch, and the third bullet is fired by the generated compressed air.

  While the set three-point firing is completed, the counter 30 is retracted by meshing with the protrusion 40 at the tip of the counter lever and the engagement recess C, and the switching portion 22 with which the mating engagement portion 32 of the counter 30 is engaged when retracting. The engaging element 31 provided on the movable terminal 23 is rotated clockwise by engagement (FIGS. 10A and 10B). The switch terminal 23 of the switching 22 is also released from the distal end engaging portion 48 of the connecting member 26 by rotation and pulled by the elastic body 28, and is separated from the fixed-side switch terminal 24, so that the current is cut off (FIG. 11). Subsequently, the switch terminal 23 is returned to the original position by the elastic body 28 and is in a non-energized state (FIG. 12).

  When the pulling of the operating element 25 is stopped, the connecting member 26 returns to the original position by the elastic body 27, and when the connecting member 26 returns, the counter stopper 34 also returns to the original position by the elastic body 45 (FIG. 13). Further, the counter 30 rotates counterclockwise by returning the counter stopper 34 to its original position, and the engagement recess C of the counter 30 is released from the empty portion 40 at the tip of the counter lever 33, and the counter 30 is moved to the right along the long hole 35. And move back to the original position (FIG. 14).

  FIG. 15 shows a two-point burst (two shots), in which the position of the counter 30 is shifted by one mountain and the protrusion 40 of the counter lever 33 is set to the position of the engaging recess B. Made possible by. Therefore, the position of the counter 30 is moved by an external operation, and the configuration for that is shown in FIG. In the case of a three-point burst, the position of the index 51 is aligned with the position of the numeral 3 in FIG. 17, and in the case of single shot or multiple shots, it is only necessary to match each set position. The illustrated index 51 uses a support shaft 42 of the counter lever 33, which is disposed in a long hole 52 of a slide plate 50 provided so as to be movable back and forth with respect to the main body, and is attached to a lower portion of the slide plate. The number of firings is controlled by determining the advance position of the counter 30 by the stop 53.

  In FIG. 15 regarding the two-point burst, the protrusion 40 at the tip of the counter lever 33 is moved to the second engaging recess B of the counter 30 as shown in FIG. Therefore, if a trigger is pulled in the case of a two-point burst, the stage of FIG. 6 to the stage of FIG. 13 will be performed in the three-point burst, and the explanation of the operation will be completely different from the explanation from the second point in the three-point burst. Since there is no place, the explanation is used and the detailed explanation is not repeated. FIG. 16 is the same as FIG. 2 at the start of the two-point burst, but FIG. 16 is shown to show that the switching unit 22 also starts from this stage at the stage of the two-point burst start. is there.

  FIG. 18 shows a semi-automatic state, that is, a one-point shot and a one-point burst state. In this state, the position of the counter 30 is shifted by two peaks, and the protrusion 40 at the tip of the counter lever 33 is set to the position of the engagement recess C. It becomes possible by setting the state. In this case, the position of the counter 30 is set by adjusting the index 51 to an index of 1 as shown in FIG. With this setting, the counter 30 is retracted by the latching portion 53 at the bottom of the slide plate, so that the protrusion 40 at the tip of the counter lever 33 is placed at the position of the engagement recess C of one engagement portion 37 of the counter 30. This corresponds to the stage of firing the third bullet in the three-point burst operation. Accordingly, when the semi-auto mode is set, the switching unit 22 is energized every time the trigger is pulled, and one firing operation is performed, which is the most saving. FIG. 19 shows the state of the switching unit 22 corresponding to the semi-auto mode.

  FIG. 20 and subsequent figures show a state of full auto, that is, continuous fire, which can be achieved by moving the counter 30 to a position where it cannot be pushed up by the counter stopper 34. The counter 30 may be shifted forward or backward, but since FIG. 20 is configured to be shifted forward, the index 51 in FIG. In the full auto mode, when the trigger of the operating element 25 is pulled, the engaging portion 48 at the tip of the connecting member comes into contact with the mating engaging portion 49 of the switch contact 23 by pushing the end points 25a, 26a, and pushes up the switch contact 23. , 24 is brought into sliding contact with each other, and the motor is activated to rotate the sector gear 22 to retract the piston 13 and to advance the piston 13 by releasing the accumulated pressure of the urging member 16 that has accumulated pressure. The operation of injecting compressed air and firing bullets is repeated.

FIG. 22 shows an example in which the counter 30 is shifted rearward so as not to be pushed up by the counter stopper 34, and is in the full auto mode. In this case, the index 51 in FIG. 17 is set to the number 0 provided by extending the long hole 52 before 1. Even in this full auto mode, by pulling the operating element 25, the tip engaging portion 48 of the connecting member 26 comes into contact with the mating engaging portion 49 of the switch contact 23 through the contact of the end points 25a and 26a, and pushes it up. Since 23 and 24 are in a conductive state, the operation of firing a bullet is connected throughout the trigger as in the full auto mode.

  As described above, according to the present invention, it is possible to control whether or not to limit the number of continuous firings of the electric gun. In particular, in the apparatus of the present invention, the number of firings can be adjusted and the number of firings can be selected by setting the position of the counter 30, and the position of the counter 30 is moved in conjunction with the firing operation to control the number of firings. It has become possible to achieve this in an appropriate and reliable manner.
