Description

Game system using pneumatic gun

The present invention relates to a game system, and more particularly, to a game system that hits a target in front of a bullet by using a pneumatic gun.

Background Art A game system for hitting a target in front using a pneumatic gun is known. For example, you can see this kind of game system in a theme park or a game room. In such a game system, a target moves and receives a certain kind of gift upon hitting the target. It would be desirable if the player could immediately select the corresponding desired gift from the multiple targets being moved. It would be even more desirable if the right gift could be delivered to the player when he hits the target. Also, from the point of view of the supplier of the game system, it would be very advantageous in terms of maintenance and management to be able to install a large amount of gifts and corresponding targets simultaneously in one game system. In addition, in the game system that targets the front target by using a pneumatic gun, if the pneumatic gun can be moved freely without fixing the specific support plate it will be desirable for the player to feel more fun.

A game system that targets a forward target using a pneumatic gun has a system for supplying bullets to the pneumatic gun. In such a system, it is desired to be able to supply only suitable bullets. That is, in supplying the bullet to the gun, there may be various impurities and the recovered bullet may be broken, so it is necessary to properly select these and supply only the appropriate bullet to the gun.

The present invention satisfies the above needs and needs. It is therefore an object of the present invention to provide a game system that targets a forward target using a pneumatic gun that allows the player to immediately select a desired gift corresponding to a plurality of moving targets. It is also an object of the present invention to provide a game system that targets a target in front of a pneumatic gun that allows the gift to be delivered to the player upon hitting the target for the selected gift. Still another object of the present invention is to allow a large amount of gifts and corresponding targets to be installed at the same time in a game system that targets the front using a pneumatic gun.

In another aspect, it is an object of the present invention to provide a game system that targets a forward target using a pneumatic gun that allows the player to hit the target while moving freely without securing the gun to the stationary plate. In addition, to provide a game system that targets the front target by using a pneumatic gun having a sorting device in which only the appropriate bullet is removed to the pneumatic gun.

The game system that hits the target in front by firing a bullet by using a pneumatic gun according to the present invention comprises a plurality of holders and a plurality of targets which are made of a material which is easily torn as mounted on the holders, and which hang gifts at the bottom thereof. And a gift supply device comprising drive means for moving the holder. The game system also has a gift feeding means for moving the gift to the shooting side, and a bullet supply device for feeding back the fired bullet to the pneumatic gun. Furthermore, the game system has a bullet sorting device disposed between the present delivery means and the bullet supply device on the path of the bullet supplying only the appropriate bullets for filtering out impurities and preserving the originals to the bullet supply device. By the gift supply device, a plurality of targets hanging on the bottom of the gift continuously move on the holder. Since the target has a gift under the target, the target can be selected immediately according to the desired gift. When the target is selected according to the presenter's desired gift and the target is hit by hitting the target, the target is torn in several hits because the target is made of a material that is easy to tear. The gift then falls from the target. The dropped gift is transported to the game player by the gift transfer means. Also, the fired bullet is transported through the gift transport device, and only the bullet whose original shape is preserved in the sorting device is sorted, and only the bullet sorted by the bullet supply device is fed back to the gun. Therefore, the player can not only gain the interest of the game of shooting against a moving target, but also by hitting the target with the desired gift. In addition, broken or broken bullets are filtered out, and only good bullets are continuously fed back into the gun, thus making it easier to manage the game machine and improve the quality of the game.

In the game system, a transparent film on which the target portion is exposed may be installed at the front of the holder. Thus, when the shot is missed, the gift can be prevented from being damaged.

In one embodiment of the invention, the drive means for moving the holder of the gift supply device comprises a pair of gears connected through a chain and a motor for transmitting power to the gears. Thus, the power of the motor drives the gears and thus the holder makes a rotary motion. In one embodiment of the present invention, the bullet sorting device comprises a sorting rod having a spiral groove formed along its circumference, a motor for rotating the sorting rod, and a panel supporting the sorting rod and the motor, The size of the groove of the spiral is slightly smaller than the diameter of the bullet. The bullet which escapes the gift conveying means flows into the groove of the sorting rod of the bullet sorting device. Since the selection rod is continuously rotated by the motor, the bullet is moved upward along the spiral, and the bullet that is broken and does not maintain its original shape is removed downward. Therefore, only suitable bullets that maintain their original shape are transferred to the bullet supply device. In one embodiment of the present invention, the bullet supply device includes a bullet containing portion accommodating a bullet, a solenoid device installed below and a block for supporting the bullet containing portion and the solenoid device and including a motor. The solenoid device here has a solenoid arm and a resilient means between the solenoid and the solenoid arm retracting to the solenoid side by the operation of the solenoid. Further, the bullet receiving portion has a handle having a sweeper connected to the motor of the block, and the base of the bullet receiving portion is formed with a first through hole communicating with the space between the solenoid and the solenoid arm of the solenoid device. In addition, the block communicates with a pneumatic gun, and has a second through hole provided with a bullet sensor and one side of the second through hole of the block is connected to the pneumatic supply means. As a pneumatic supply means, a compressor is used. The bullet selected through the bullet sorting device is transferred to the bullet receiving portion of the bullet supply device. The handle installed in the bullet container is rotated by a motor installed in the block so that the sweeper pushes the bullet into the first through hole of the bullet container. The bullet is then transferred to the space between the solenoid and the solenoid arm through the first through hole. When the solenoid device is operated, the bullet transferred to the space between the solenoid and the solenoid arm through the first through hole is pushed into the second through hole due to the retraction of the solenoid arm, and the pneumatic supply means Pneumatic pressure is injected into the second through hole by the bullet detection of the detection sensor to feed the bullet back into the pneumatic gun.

In another aspect of the invention, the fired bullet is fed back to the pneumatic gun through the hose. Here, the chain is disposed in the hose along the longitudinal direction of the hose. As a result, the hose maintains rigidity and the shooter is free to move the pneumatic gun. Also, in this case, in order to prevent the risk of bullets being fired out of the shooting position, in the game system, a pneumatic gun position sensor for detecting the pneumatic gun in the shooting position is installed at the shooting position of the game system. The sensor detects the pneumatic gun so that it can only be fired when it is detected that the pneumatic gun is in the shooting position.

The invention will now be more fully understood by the embodiments described with reference to the accompanying drawings.

The player can shoot by putting the pneumatic gun into the box 10 through the injection hole. The pneumatic gun holder is installed in the lower part 13 of the injection holes 11 and 12 to store the pneumatic gun while shooting is not in progress. A gift supply opening 14 is formed at the bottom of the front of the box 10. This allows the shooter to receive a gift.

2 shows that in the game system according to the present invention, the gift supply device 100 is installed inside the box 10. The gift supply device 100 has a plurality of holders 101 and is equipped with a gift target made of a material that is easy to tear at the bottom thereof, such a target is suspended from the gift (see Fig. 7). The target is made of paper, torn by several hits, and the gift falls down. The holders 101 achieve a continuous rotational motion in the present embodiment by means of drive means (see FIGS. 8 and 9). The present supply device 100 is seen to be installed on the rails 110 and 120 in this embodiment. As will be described later, this is for the horizontal movement of the gift supply device. In addition, another box 200 is shown in the first half inside the box 10, where a bullet supply device and a bullet sorting device are installed. Reference numeral 30 denotes a compressor, which constitutes a pneumatic supply means. This provides compressed air for feeding the bullet back into the air gun as described below. In addition, a power supply unit 160 and a main board 130 that manages electrical control of the game system are installed in the first half of the box 10. The pneumatic gun position sensor 150, which detects that the pneumatic gun is in the shooting position, that is to say that it is arranged inside the box and ready to shoot through the air gun inlets 11, 12. It may be installed at a portion corresponding to the rear plane of the. In addition, the box 200 may be provided with a gift detection sensor 180 for detecting that the gift has arrived.

3 illustrates the overall operation of the present invention. Examples of the present transfer device 300, bullet sorting device 250, bullet feedback device 280 is shown in this figure. When the target mounted on the holder 101 of the gift supply device 100 is torn by several hits, the gift falls to the bottom. The gift 50 dropped in this way is dropped onto the gift transfer means 300, and moved to the shooting side. In this embodiment, the conveying means is a conveyor belt (300). In this case, falling onto the conveyor belt 300 includes not only the gift 50 but also impurities such as the broken bullet generated when the shot bullet and the target are torn. The bullet 5 and the gift 50 are moved through the conveyor belt 300, and when the conveyor belt 300 is removed, the gift 50 'falls to the inclined plate 210 and slides along its slope to the box 10. Is provided to the shooter through the front opening 14. The bullet 5 and other impurities fall into the bullet sorting device 250 through the space between the conveyor belt 300 and the plate 210. The bullet sorting device 250 filters the impurities and broken bullets and transfers only the good bullets whose original shape is preserved to the bullet supply device 280. The bullet supply device 280 feeds the bullet back to the pneumatic gun using the compressed air pressure of the compressor 30.

4, 5 and 6 show an example of the gift supply device 100.

First, referring to FIG. 4, the frames 103 and 103 ′ are provided with upper gears 105 and 105 ′ and lower gears 107 and 107 ′. The upper gear 105 or 105 'on each frame 103 or 103' is connected to the corresponding lower gear 107 or 107 'via chains 112 and 112'. A plurality of holders 101 are mounted in holes formed in the chain between the facing chains 112, 112 ′ as shown. The gear is powered by a drive motor. This example is shown in FIG. 5. That is, the holder drive motor 115 transmits power to the lower gear 107 'by the belt 111. Reference numeral 108 is a mounting portion for attaching the belt to the lower gear 107 '. Therefore, when the holder drive motor 115 is operated, the holders continuously rotate from bottom to top (or vice versa). Each holder has a target (not shown) at the bottom thereof. As will be described later, the target is hanging a gift underneath. The target is also made of a material that is easily torn, such as paper. Therefore, after the game is started, the holders are driven by the operation of the holder drive motor 115 so that the holders continue to rotate from bottom to top (or vice versa), and the shooter selects a target corresponding to the desired gift. Can shoot. Therefore, it is possible to obtain the fun of shooting a target to exercise while at the same time double fun to get the desired gift. Here, the present supply device has been described that the rotational movement in the vertical relationship, but also those skilled in the art can be configured to easily achieve the rotational movement in a horizontal relationship.

From the point of view of managing the game machine, if the targets are mostly lost by hits (and therefore the gifts are also lost), these targets should be newly installed in the holders. For this purpose, it is preferable if the gift supply device 100 can be moved to the front of the game machine box 10. 4 and 6 also show examples that satisfy this need. The frames 103, 103 ′ are mounted on the rails 110, 120. In other words, the frame is a linear reciprocating motion on the rail. Frame reciprocating motor 125 is installed on the frame for the linear reciprocating motion, the rotational force of the motor is transmitted to the roller 126 through the pinion gear (121, 122). The roller 126 is connected via the roller 126 ′ of the opposite frame and the pinion shaft 128. The frame also has idle rollers 127 and 127 '. Therefore, as shown in FIG. 6B, the frame forms a linear motion on the rails 110 and 120 as the motor 125 rotates. The direction of rotation of the motor will determine the direction of linear movement of the frame. As described, the shooting game machine according to the present invention can load a large amount of gifts at a time because the present supply apparatus has a target having a plurality of holders and each holder has a plurality of gifts. have. In addition, the gift supply device is a linear movement to the front of the box 10, it is convenient to replace the gift. Accordingly, the present invention provides a shooting game machine that can install a large amount of gifts and corresponding targets simultaneously in one game system and is easy to replace. This is very advantageous in terms of maintenance and management of game machines.

Figure 7 shows that the target used in the present invention is installed in the holder (101). As shown, the gift 4 is suspended from the lower part of the target 2. The target is made of a sticky material, like a piece of paper, and can be torn by a few hits (usually around 10). The gift 4 will then fall into the gift transfer means 300 at the bottom.

8 shows that a transparent film 190 is installed in front of each holder 101. For example, the transparent film 190 may use a vinyl film. In the transparent film, as shown, the portion corresponding to the target portion is revealed by cutting away from the vinyl film. Therefore, the shooter is aimed toward the target portion 191 is seen. By this transparent film, first, when the fired bullet misses the target part, the bullet can be prevented from hitting the gift, and second, from the holder which rotates in two rows and moves to the back row of holders. It is possible to prevent the mounted target or gift from being damaged by bullets that are not hit against the front row. Therefore, the player must hit the target before the gift he is aiming to turn to the back row, or wait until it returns to the front row. 9 shows the present gift feeding device in which the transparent membrane is installed.

Further, in the gift supply device 100, position sensors (not shown) may be installed on the rear wall of the frames 103 and 103 ′ and the inner wall of the first half of the box 10. Then, these sensors can be notified that the frames 103 and 103 'arrive at the rear end or the front end of the box, respectively. At this time, unnecessary power consumption can be prevented by cutting off the power to the motor 125 for the line movement of the frame.

As described with reference to FIG. 3, the gift dropped by the hit, the fired bullet and other impurities are transferred through the conveyor belt 300 while the gift is delivered to the shooter through the inclined plate 210 and the bullet. Is transferred to the bullet sorting device 250, and the bullet sorting device 250 transfers only the good bullets whose original shape is preserved by filtering impurities and broken bullets, etc. to the bullet supply device 280. 10 and 11 show an example of a bullet screening device according to the present invention. The bullet sorting device 250 is composed of a sorting rod 251 and a sorting rod rotating motor 254 for revolving the sorting rod 251 and a panel supporting them. FIG. 10 (a) shows the sorting apparatus 250 as viewed from above, and FIG. 10 (b) shows the viewed from below. The selection rod 251 is a rod having a spiral groove as best seen in FIG. 10 (b). As shown in Fig. 10 (a), the panel covers the sorting bar so that only a portion of the sorting bar is exposed at the bottom thereof on its upper surface. The sorting device is also inclined at an angle. The bullet out of the conveyor belt 300 falls into the sorting device 250, and the dropped bullet flows down along the inclination of the panel and flows into the spiral groove of the sorting bar exposed from the lower portion thereof. The bullet flowing into the spiral groove of the sorting rod 251 moves upward along the spiral because the sorting rod is continuously rotating. Here, the groove of the spiral of the selection rod has a size slightly smaller than the direct hit of the bullet. The bullet, which begins to climb along the groove at the lower end of the selection rod, rotates through the spiral groove to reach the upper end position of the inclined selection rod to escape the groove. In this process, due to the vibration of the selection rod, friction between the bullet and the spiral groove wall, the bullet rotates itself (see Fig. 11 (d)), and the bullet which is broken or fragmented and cannot maintain a circle is stuck in the spiral groove. It is not soft and falls down before reaching its upper end. (See FIG. 11 (a), (b), (c), (d), (e).) Although the bullet has been described, it is apparent that other impurities can be filtered in the same manner.

Only the bullet thus sorted is transferred to the bullet supply device 280 and the bullet supply device returns the bullet to the pneumatic gun using the air pressure of the compressor 30.

12 and 13 show an example of a bullet supply device 280. FIG. 12 is a perspective view of the present bullet supply device, and FIG. 13 is a side cross-sectional view of FIG. The bullet supply device 280 has a bullet accommodating part 283 for receiving the bullet selected through the bullet screening device 250 and a block 287 disposed below it. The bullet receiving portion 283 has through holes 284 and 284 'penetrated downwardly from its base as shown. The bullet receptacle 283 has a handle 81 at its center, which is connected to a motor (not shown) installed in the block. The handle 81 also has a sweeper 82. The solenoid device 285, 285 'is provided in the upper part of the block 287. Solenoid devices 285 and 285 'have solenoids 2851 and 2851' and solenoid arms 2853 and 2853 'and springs 2852 and 2852' between the solenoid and arms. Therefore, the solenoid arm retracts to the solenoid side by the operation of the solenoid, and when the solenoid is off, the solenoid arm returns to the original position by the restoring force of the spring. The through holes 284 and 284 'formed at the base of the bullet receiving portion 283 are the solenoids 2851 and 2851' and the arms 2853 and 2853 when the solenoids are turned off in the solenoid devices 285 and 285 '. It communicates with the space formed between them. The block 287 has a vertical through hole 72 which communicates with the pneumatic gun through the communication line 79. In addition, the vertical through hole 72 communicates with the compressor 30 through the hoses 291 and 292. Reference numeral 70 denotes a communication section at the block 287 to which the hose is connected. The high pressure hose 291 and the low pressure hose 292 are connected to this communicating part 70 by the valve 80 at the same time. The vertical through hole 72 is provided with a bullet sensor (not shown) for detecting that the bullet has reached. Referring to Figs. 13A and 13B, the operation of the present feeding apparatus will be described. Here, the number added to the inside of the bullet 5 indicates its position. First, referring to FIG. 13A, first, the handle 81 of the bullet accommodating part 283 rotates the sweeper 82 while rotating by a motor installed in the block to pass through the bullet dropped in the accommodating part. 284, 284 '). As a result, the bullet 5 is moved to the first position. The bullet then falls along the through holes 284 and 284 'and reaches the space between the arms 2853 and 2853' and the solenoids 2851 and 2851 'in the solenoid devices 285 and 285'. That is, reach the second position. Referring to Fig. 13 (b), after the bullet reaches the second position, the solenoid is turned on so that the solenoid arm is retracted, which pushes the bullet into the through hole 72 of the block. The bullet 5 thus reaches the third position. At this time, the solenoid is turned off and the solenoid arm 287, which has retracted, returns to its original position by the restoring force of the spring 283. When the bullet reaches the third position, the bullet detection sensor detects this and air of low pressure is supplied from the compressor through the low pressure hose 292 to be injected into the communication unit 70 of the block. As a result, the bullet is supplied to the pneumatic gun through the communication line (79). When the bullet is not fed back to the pneumatic gun despite a certain number of operation of the solenoid, high pressure compressed air is injected into the communication unit 70 through the high pressure hose 291. This ensures the return of the bullet to the pneumatic gun which is caught in the through hole 72 of the block 287 or the connection line 79 of the through hole 72 and the pneumatic gun.

FIG. 14 shows the communication line 79 connecting the bullet supply device 280 to the pneumatic gun in the middle thereof. The communication line is a hose, the chain 791 is provided in the hose 79 along the longitudinal direction of the hose. The installation of the chain 791 may ensure that the shooter freely moves the pneumatic gun 792. When simply connecting the pneumatic gun with only the hose 79, the hose 79 is twisted when the shooter freely moves the gun. However, this phenomenon can be prevented by installing the chain 791 therein, and the shooter can feel the fun of the game more. The pneumatic gun position sensor 150 (see FIG. 2) installed under the pneumatic gun inlets 11 and 12 detects that the shooter is ready to shoot by putting the pneumatic gun into the inlet. The gun is activated only when the sensor 150 detects that the pneumatic gun is in the shooting position. Therefore, as in the present invention, in a system capable of freely moving a pneumatic gun, the bullet is prevented from being fired at a position other than shooting. In addition, the gift detection sensor 180 detects that the gift has reached the shooting person, and when the present sensor detects the gift, for example, music can flow out to notify the shooting person of the arrival of the gift.

It will be appreciated that the various objects described above have been achieved by the present invention. Although the present invention has been described with reference to the examples, it will be apparent that the present invention is not necessarily limited thereto, and the scope of the present invention is defined by the following claims.
