Description

Cut-off device for electric mechanism in imitation gun

Technical Field

The present invention relates to a cutting device for an electric mechanism in a simulated gun. The simulated gun has the following structure: a piston-cylinder mechanism, wherein the electric mechanism drives a movable portion thereof in one direction to accumulate pressure in a pressurizing member, and when the pressurizing member is released, the piston-cylinder mechanism is driven in a direction opposite to the aforementioned direction, thereby generating compressed air for firing a bullet.

Background Art

Among imitation guns, there are so-called electric guns. These are based on the invention of the automatic airgun filed by the applicant of this application, Japanese Patent Publication No. Hei 3-221793 (Japanese Patent Publication No. Hei 7-43238). They are widely used because they do not have to worry about gas shortages, as with gas guns. Some electric guns have a firing mode selection mechanism that allows selection between a single-shot mode, known as semi-automatic mode, in which the gun fires once each time the trigger is pulled, and a continuous-fire mode, known as full-automatic mode, in which the gun fires continuously while the trigger is pulled.

The firing mode selection mechanism is controlled by switching the motor's drive circuit on and off, necessitating some form of linkage between the trigger operation and the motor. The trigger is typically located close to the motor that drives the piston-cylinder mechanism. Therefore, existing electric guns utilize a sector gear driven by the motor to link the trigger and motor, controlling the on/off switch. This sector gear meshes with a rack mounted on the piston side, retracting the piston. Therefore, each rotation of the sector gear triggers a shot, making it suitable for on/off control.

The sector gear is located close to the electric motor, the driving source. To achieve interlocking operation between the sector gear and the switch, they must be positioned close together. This requirement for close positioning of the sector gear and the switch creates a limitation, reducing the flexibility in the layout of the piston-cylinder mechanism and electric mechanism within the simulation gun. Furthermore, this limitation is not limited to layout; in simulation guns where the sector gear is relatively far from the trigger, motorization is difficult to achieve. Therefore, when modeling a long-gun electric gun using the aforementioned conventional method, for example, shortening the piston-cylinder mechanism is the only option, which can hinder product development.

Furthermore, in the invention of Japanese Patent Laid-Open No. 2006-300462, after the motor is powered off, the sector gear disengages from its meshing with the rack due to inertial rotation, and the movable component of the piston-cylinder mechanism returns to engage with the trigger, thus achieving reliable switching. This method is essentially the same as the invention of Japanese Patent Laid-Open No. 3-221793. However, this method requires a very limited arrangement of the sector gear and switch, which is common knowledge. Consequently, there is a problem: even if the model is a long-length, front-to-back electric gun, the piston-cylinder mechanism can only be shortened, and as long as this conventional method is used, the sector gear and switch cannot be arranged separately.

Summary of the Invention

Technical issues to be solved by the invention

The present invention was completed in light of the aforementioned perspective, and its object is to provide a switch disconnection control that is independent of a sector gear, thereby eliminating layout restrictions on piston-cylinder mechanisms and electric mechanisms in a simulation gun. Furthermore, another object of the present invention is to provide a device for disconnecting the electric mechanism in a simulation gun that can be easily adjusted to the length of a long-gun model electric gun, for example.

Means for solving technical problems

In order to solve the above-mentioned problem, the present invention is a cutting device for an electric mechanism in a simulation gun, the simulation gun having the following structure: a piston-cylinder mechanism, wherein the electric mechanism drives its movable part in one direction to accumulate pressure in a pressurizing member, and the pressurizing member is released to drive the piston-cylinder mechanism in a direction opposite to the above-mentioned direction to generate compressed air for firing a bullet, and the cutting device for the electric mechanism in the simulation gun has the following structure: a switching mechanism for controlling the driving circuit of the electric motor so as to select any one of the following modes: a single-shot mode, in which a single reciprocating action of the piston-cylinder mechanism is used to fire a bullet; The invention relates to a method for firing multiple bullets in a continuous firing mode, wherein the plurality of bullets are fired by a plurality of continuous reciprocating movements of the piston-cylinder mechanism. The switching mechanism comprises: a selector portion, which is provided for selecting at least the single-shot mode and the continuous firing mode; a switch, which turns off the drive circuit by operating the trigger; and a cut-off component, which, when the single-shot mode is selected, cooperates with the unidirectional drive of the above-mentioned movable portion to cut off the switch. The engaging portion between the movable portion of the piston-cylinder mechanism and the cut-off component is set in front of the reciprocating direction of the movable portion, thereby expanding the range of timing selection from the time when the movable portion starts to retreat to the time when the above-mentioned front portion engages with the cut-off component.

The imitation gun of the present invention has the following structure: a piston-cylinder mechanism. A motorized mechanism drives its movable portion unidirectionally, thereby accumulating pressure in a pressurizing member. Release of the pressurizing member drives the piston-cylinder mechanism in the opposite direction, generating compressed air for firing a bullet. The piston-cylinder mechanism is a combination of a cylinder and a piston. In most cases, the piston serves as the movable portion, reciprocating relative to the cylinder to generate compressed air. However, the reverse configuration is also possible. The portion that moves to compress the air is referred to as the movable portion in the present invention.

The pressurizing member that accumulates pressure in the movable part is often an elastic component, typically a coil spring. This spring releases the accumulated pressure instantly, allowing the movable part to operate instantly, making it easier to obtain compressed air. Furthermore, it is desirable that the reciprocating length of the movable part be shorter in a so-called short-gun model and longer in a long-gun model. However, according to the present invention, the front-to-back length is not a limitation, but rather facilitates accurate reproduction of the model.

The cutting device of the present invention includes a switching mechanism for controlling the drive circuit of the electric motor, thereby selecting one of the following modes: a single-shot mode, in which a single round of firing is performed by a single reciprocating motion of the piston-cylinder mechanism; and a continuous-fire mode, in which multiple rounds of firing are performed by multiple consecutive reciprocating motions of the piston-cylinder mechanism. While this structure itself is not novel, the inclusion of the switching mechanism is a necessary condition of the present invention.

The switching mechanism comprises a selector portion configured to select between at least a single-shot mode and a continuous-fire mode; a switch that shuts off a drive circuit upon operation of a trigger; and a cutoff component that, when the single-shot mode is selected, cooperates with the unidirectional drive of the movable portion to cut off the switch. In the present invention, the cutoff component operates by engaging with the movable portion, thus not relying on a sector gear. Furthermore, the single-shot mode is used in the sense of a firing mode at a time; since it does not mean firing a single round, in the case of a simulated gun with multiple barrels, multiple bullets can be fired with a single firing operation.

The engagement point between the movable portion of the piston-cylinder mechanism and the cutting member is set at the front portion of the movable portion in the reciprocating direction. This configuration allows for a wider range of timing options from the start of the movable portion's retreat until the front portion engages the cutting member. Engagement at the front portion of the movable portion in the reciprocating direction allows for a longer time until engagement than engagement at the rear portion. While short engagement times allow inertial force to cause cutting, sufficiently long engagement times allow dynamic force to cause cutting, further improving reliability.

The simulated gun is a long-lance type, with the piston-cylinder mechanism and the electric mechanism separately arranged. A preferred configuration is to have the piston-cylinder mechanism be longer than a typical piston-cylinder mechanism. The longer the piston-cylinder mechanism travels, the more powerful compressed air can be generated, but this requires fewer restrictions on the length of the piston-cylinder mechanism. On the other hand, if the piston-cylinder mechanism has a sufficient travel, the engagement point between the movable portion of the piston-cylinder mechanism and the cutting component tends to be further away from the trigger. In this case, the present invention can also easily form a cutting device with an electric mechanism.

Effects of the Invention

The present invention, constructed and operating as described above, achieves the following effects: It can control the disconnection of the electric mechanism without relying on a sector gear, eliminating layout restrictions on the mechanism or electric mechanism in a simulation gun. Furthermore, since the time until engagement can be set sufficiently long, the electric mechanism is disconnected by power, further improving reliability. Furthermore, the present invention can provide a device for disconnecting the electric mechanism in a simulation gun that can be easily implemented even in a long-gun model electric gun, for example.

DETAILED DESCRIPTION

The present invention will be described in more detail with reference to the following illustrated embodiments. FIG1 is an overall view of a long-gun-type imitation gun to which the cutting device of the present invention is applied. The imitation gun is a multi-bullet-firing electric gun G. The electric gun G has three barrels 11, 12, and 13. The compressed air generating unit 10 is configured to include a cylinder assembly 20 consisting of three cylinders 21, 22, and 23, a piston assembly 30 consisting of three pistons 31, 32, and 33, and an electric mechanism 40 that drives the piston assembly 30.

A loading assembly 50 is located at the rear of the barrels, with a detachable magazine 51 mounted below it. Within the loading assembly 50, a loading section 14 for loading bullets B is located within the rear ends of the three barrels 11, 12, and 13. A cocking mechanism 15 for trajectory adjustment is also located within the loading section 14. Furthermore, the rear ends of the three barrels 11, 12, and 13 are covered with a connecting package 16, which is made of a flexible material such as rubber and has sealing properties (Figure 2).

The compressed air generator 10 is the component of the multi-bullet-firing electric gun G that generates the air ejected for each bullet B, allowing the bullets B to be fired from the respective barrels 11, 12, and 13. When viewed from the front, the three barrels themselves form a triangular shape, and the compressed air generator 10 is positioned within and behind the electric gun G. The cylinder assembly 20, piston assembly 30, and electric mechanism 40 that constitute the compressed air generator 10 are arranged in this order in a generally straight line.

The cylinder assembly 20 comprises three cylinders 21, 22, and 23 located behind the three barrels 11, 12, and 13. Air jet nozzles 24 are located at the front ends of the cylinders, and pistons 31, 32, and 33 reciprocate within the cylinders. The illustrated cylinder assembly 20 comprises three tube members 25; a front fixing member 26 securing each tube member 25 to the front end; and a rear fixing member 27 securing each tube member 25 to the rear end (see Figures 3 and 4).

The air jet nozzle 24 is mounted on the front fixing member 26, and a piston insertion port 25a is formed in the rear fixing member 27. The jet nozzle 24 is mounted on the front of a duct mounting member 25b, which is attached to a stopper 25c on the rear of the front fixing member 26. The duct mounting member 25b is positioned so as to fit within the tube member 25 and is assembled airtightly using a sealing member 26a ( FIG. 4 ).

As shown in the illustrated embodiment, an inter-nozzle 28 is connected to the loading unit 14 and the air injection nozzle 24. This inter-nozzle 28 is arranged to be movable forward and backward via a nozzle base 29. The inter-nozzle 28 slides airtightly relative to the injection nozzle 24 and is positioned to inject compressed air generated by the compressed air generating unit 10 toward the bullet. The inter-nozzle 28 is attached to a rising portion 29a of the nozzle base 29 and is assembled to the main body of the simulation gun G so that it can move forward and backward.

Thus, as the pistons 31, 32, and 33, described later, retract, the connecting nozzle 28 retracts by engaging with the latching teeth 49, described later, and is advanced by the spring acting on the biasing member 29b of the nozzle base 29 (see FIG2 ). Furthermore, the connecting nozzle 28 is configured such that its front end also slides airtightly relative to the connecting package 16, moves away from the connecting package 16 and retracts to open a gap for the bullet B to be pushed up to the rear end of the barrel, and then advances to push the bullet B into the loading section 14.

The air injection nozzle 24 is positioned near the center of each of the three cylinder tubes 25, 25, 25. This is a countermeasure for the following reasons: since there are only three gun barrels 11, 12, and 13 in the illustrated example, it is impossible to align the center of the cylinder tubes, which have a larger diameter than the gun barrels. Therefore, the position of the air injection nozzle 24 is determined by the relationship between the center positions of the gun barrels and the cylinder tubes.

The piston assembly 30 includes three pistons 31, 32, and 33 that reciprocate within cylinders 21, 22, and 23 to generate compressed air. These three pistons 31, 32, and 33 are joined together at a rear joint 34, and a piston shaft 35 having a rack 36 extending in the reciprocating direction is integrally formed with the joint (see FIG5 ).

The three pistons 31, 32, and 33 maintain flexibility while engaging with the joint 34, thereby maintaining sealing performance between the pistons 31, 32, and 33 and the inner wall of the cylinder. Specifically, the piston and cylinder that comprise the piston-cylinder mechanism tend to achieve higher compression ratios when their positional relationship or mating precision is high. To achieve this, their respective axis centers must also be aligned with high precision. However, maintaining a certain degree of flexibility allows for achieving high compression ratios without requiring excessive precision.

To achieve this flexibility, the present invention employs a structure in which pistons 31, 32, and 33 are mounted at the distal end of an elongated rod 37, and are axially fixed to the rear of the rod 37 at a joint 34 for movement. In the illustrated embodiment, the rod 37 is axially fixed using a support shaft 37a extending horizontally relative to the piston's reciprocating motion, allowing for vertical movement. Furthermore, O-rings (illustrated) are used as sealing members 38 on the pistons 31, 32, and 33 to maintain airtightness.

In the embodiment where the piston-cylinder mechanism comprises three groups, the structure is as follows: As described above, the three groups of piston assemblies 30 are combined to form a triangular shape when viewed from the front. The piston shaft 35 is positioned at the joint 34, offset below the center of the three groups, and the rack 36 is located above the offset portion. Therefore, the rack 36 is positioned near the center of the three groups, providing space 39 for the output gear 41 of the electric mechanism 40. Furthermore, the driving force from the output gear 41 is more efficiently transmitted from a position closer to the centerline.

The electric mechanism 40 is configured as follows: while retracting the piston assembly 30, it accumulates pressure in the elastic member 42 and drives the output gear 41, which meshes with the rack 36, to release the accumulated pressure, thereby compressing the air. For detailed explanation, see Figure 6 . Reference numeral 43 denotes an electric motor, 44 denotes a pinion mounted on its rotating shaft, and 45 denotes a reduction gear train consisting of multiple gears meshing with the pinion. The output gear 41 is a sector gear. The sector gear 41 has a toothed portion 41a that meshes with the rack 36 to retract the piston assembly 30, and a toothless portion 41b that does not mesh with the rack, allowing the piston assembly 30 to advance.

The piston shaft 35 has a hollow structure and is biased in the forward direction by an elastic member 42, which acts as a coil spring, within the hollow interior. One end of the elastic member 42, formed of the coil spring, contacts the front end of the piston shaft's hollow interior, while the other end is supported by the piston's moving portion 46, or the rear end of the cavity, located within the motor mechanism 40. A guide portion 47, comprising a concave-convex structure, is provided along the longitudinal side of the piston shaft 35. This portion engages with a protrusion 46a, formed of a concave-convex structure on the gun body, functioning as a guide for straight forward movement (see Figure 6).

In addition to the above, the multi-bullet electric gun G of the embodiment is equipped with a power supply battery (not shown) or a circuit connecting the power supply battery and the electric motor 43, a switch for turning the power on and off, and other mechanisms necessary for the operation of the electric gun. Reference numeral 18 denotes a switch, 19 denotes an outer barrel housing the three barrels, 48 denotes a selector for selecting the firing mode, and 49 denotes the aforementioned latching member. The latching member 49 is configured as an engaging member that is vertically movable at the rear end of the nozzle base 29 and is axially fixed by a support shaft 29a. It can be retracted by engaging with an engaging portion 49a provided on the piston shaft 35 and can be released by contacting a release portion 49b provided on the gun body. Reference numeral 49c denotes a spring that urges the latching member 49 in the direction of engagement with the engaging portion 49a (see FIG. 2 ). Furthermore, the spring 29b acts as a urging member on the nozzle base 29, acting forward to push the supplied bullet B toward the loading section 14.

The cutting device of the present invention blocks the operation of the electric mechanism 40, which is activated by trigger operation, in a simulated gun G having the above-described structure. As will be understood from the description so far, the simulated gun G is a long-pistol type, and pistons 31, 32, and 33 can only retract a portion of their stroke. Consequently, the piston-cylinder mechanism has a maximum length greater than twice the stroke, and the electric mechanism is positioned at the rear end of the piston-cylinder mechanism. This piston-cylinder mechanism has a longer stroke than conventional piston-cylinder mechanisms, making it easier to generate compressed air at the required pressure.

The cutting device of the present invention selects one of the following modes: a single-shot mode, in which a single bullet is fired with a single reciprocating motion of the piston-cylinder mechanism; and a continuous-fire mode, in which multiple bullets are fired with multiple reciprocating motions of the piston-cylinder mechanism. To this end, a switching mechanism 55 is provided for controlling the drive circuit of the motor 43. The switching mechanism 55 comprises: a selector operating unit 52, provided for selecting at least the single-shot mode and the continuous-fire mode; a switch component 53, which constitutes the switch 18 that closes the drive circuit when operated by a trigger; and a cutting component 54, which cooperates with the unidirectional drive of the movable unit to open the switch component 53 when the single-shot mode is selected (see FIG. 7A ). Furthermore, the selector operating unit 52 is located on the opposite side of the cutting component 54 (see FIG. 7B ).

In the embodiment, the selector operating unit 52 is configured to select the following three modes: safety mode (S), which locks the trigger 17 so that it cannot be operated; single-shot mode (D), which fires a single round with a single trigger operation; and continuous-fire mode (F), which fires any number of rounds while the trigger 17 is being operated (see FIG7B , etc.). The selector operating unit 52 is rotatably assembled to the mounting member at the bottom of the cylinder assembly via a support shaft 52a and includes a selector pawl 56 coaxial with and located on the opposite side of the support shaft 52a; and a selector member 57 meshing with a gear 56a coaxial with the selector pawl 56 and capable of being moved forward and backward by its rotation (see FIG8B ). 57a represents the rack teeth used for this meshing, and the gear 56a is located on the back side of the selector pawl 56.

The switch member 53 constitutes the switch 18. Its main body is rotatably supported on a switch mounting member 53b via a support shaft 53a. A spring 53e is mounted on the main body of the switch member 53, acting in the on/off direction (see Figure 9). The switch member 53 is electrically conductive when a core 53c at the front end of the main body contacts a switch terminal 53d, and is disconnected when no contact is established. Furthermore, the switch member 53 has a rear portion 53f that is pressurized by a pressurizing portion 17a located above the trigger 17. Consequently, the trigger 17 is provided with a spring 17c that acts in a direction that resists pulling.

The cutoff member 54 is rotatably mounted on the gun body via a support shaft 54a. One end 58 of the cutoff member 54 extends toward the rear end of the piston-cylinder mechanism, and the other end 59 extends toward the switch member 53. One end 58 is formed into a generally L-shaped structure to engage with the head of one of the movable pistons 31, 32, and 33, namely, the piston 33. To facilitate this engagement, a notch 23a, where the rear end of the head is exposed, is formed in the rear end of the corresponding cylinder 23. The other end 59 of the cutoff member 54 is configured to engage with a portion 53g formed on the switch member 53 (see FIG7A ). Furthermore, the cutoff member 54 is biased by a spring 54b toward the direction in which the one end 58 contacts the notch 23a of the cylinder (see FIG8A ).

A trigger locking portion 60 is combined with the trigger 17. The trigger locking portion 60 is axially supported so as to be movable as a whole with the selector member 57, and has a protrusion fixing portion 60a that fixes the trigger 17 by engaging with the protrusion 17b provided on the trigger 17. The selector locking portion 60 is formed as a whole with the selector member 57, so that the trigger 17 can be operated by the mode selection operation of the selector operating portion 52. In addition, the selector pawl 56 is fixed at the position of the three modes so as to produce a step sense, but the mechanism for imparting the step sense can be implemented by an existing well-known method. The above-mentioned three modes are indicated by a display 61 such as safety: S, semi-automatic: ·, and fully automatic: F (refer to Figure 7B, etc.).

The operation of the cutting device of the present invention thus constructed will be described with reference to the following figures, including FIG10 . Assume that the imitation electric gun is in a state in which it can be operated. FIG10A clearly shows the safe state, as can be seen from the position of the selector operating portion 52. Since the pistons 31, 32, and 33 are in the forward position and the trigger locking portion 60 is locked in the trigger 17, the piston-cylinder mechanism cannot operate the trigger 17. Furthermore, the switch member 53 constituting the switch 18 is in the off state, and the cutting member 54 has one end 58 protruding inward from the notch 23a of the cylinder 23. In this state, the selector operating portion 52 is switched to semi-automatic mode, and the selector member 57 is moved rearward, thereby releasing the lock of the trigger locking portion 60 and allowing the trigger 17 to be pulled ( FIG10B ).

When the trigger 17 is pulled, the pressurizing portion 17a on the upper portion pressurizes portion 53f of the switch component 53, causing the pressed core portion 53c to contact the switch terminal 53d, and the switch component 53 is turned on (Figure 11A). The drive circuit is closed by the conduction of the switch component 53, and the pistons 31, 32, and 33 begin to retract through the activation of the electric mechanism 40. When the pistons 31, 32, and 33 reach the retraction limit and contact one end 58 of the cutting component 54, pressing it downward, the cutting component 54 rotates counterclockwise in the figure (Figure 11B). This rotation causes a portion 53g of the switch component 53, which is engaged with the other end 59 of the cutting component 54, to be lifted, separating the core portion 53c and the switch terminal 53d, thereby turning off the switch 53 (Figure 12A). In other words, the pistons 31, 32, and 33 are reliably driven to the retraction limit. After the pistons 31, 32, 33 start to retreat, the engaging tooth member 49 engages with the engaging hand portion 49a, and the engagement is released by the releasing portion 49b. The next round of ammunition is loaded until the nozzle base 29 retreats and advances.

Simultaneously with the disconnection of switch member 53, sector gear 41 of electric mechanism 40 moves from toothed portion 41a to toothless portion 41b, disengaging from rack 36. As a result, the accumulated pressure in elastic member 42 is released, and pistons 31, 32, and 33 instantly move to their forward limit. The air within the cylinder is compressed and ejected from injection nozzle 24 as compressed air (Figure 12A). As pistons 31, 32, and 33 advance, shutoff member 54 is positioned so that one end 58 protrudes toward the rear end of cylinder 23, while the other end 59 lowers and does not lift switch member 53, completing the shutoff (Figure 12B). This completes the single-shot mode, where a single reciprocating motion of the piston-cylinder mechanism fires a single bullet, firing one bullet from each of three barrels 11, 12, and 13, for a total of three bullets B.

By switching the selector operating unit 52 to full-auto mode (F), bullets B can be fired continuously. In full-auto mode, the trigger latch 60 and selector member 57 retract further as the selector operating unit 52 is switched. As the trigger latch 60 retracts, its cam portion 60b engages with the engaging portion 54c provided on the cutoff member 54 (see Figure 13). The engagement of the cam portion 60 with the engaging portion 54c causes the cutoff member 54 to rotate and move upward according to the shape of the cam surface. The cutoff member 54 rotates and moves upward, away from the switch 53, and the cutoff mechanism is disabled. As a result, while the trigger 17 is continuously pulled, the switch member 53 remains in the on state, and the piston-cylinder mechanism repeatedly reciprocates, allowing three bullets B to be fired continuously.
