Description

Shooting game apparatus using compressed air

Technical Field

The present invention relates to a shooting game apparatus, and more particularly, to a shooting game apparatus that uses compressed air of a relatively low pressure to send bullets from a bullet feeding apparatus to a shooting apparatus and uses compressed air of a relatively high pressure to eject the bullets from the shooting apparatus.

Background

Shooting game entertainment has been widely used so far, typically with shooting devices such as guns or bows, and furthermore, computer simulation shooting games are being developed recently. Among these shooting games, the shooting game using compressed air is most enjoyable because the game has a sense of reality due to vibration and explosion sound generated when bullets are fired from the shooting apparatus. Furthermore, if the target is a prize such as a doll, players may prefer the game because they have many choices in prizes, and the prizes may be available on the spot when the target is hit.

However, the conventional shooting game apparatus using compressed air has problems. The compressed air generated by the air compressor is directly supplied to the plurality of shooting devices, and therefore, the pressure of the compressed air supplied to the shooting devices is varied according to the number of the shooting devices and the distance between the shooting devices and the air compressor. Thus, the pressures sent to each firing device are different from each other. Therefore, it is difficult to expect a reliable shooting speed or straight advance of the bullet.

In addition, moisture generated from an air compressor installed in the shooting game apparatus is collected by the collection container. Therefore, if the moisture collected in the collection container is not removed at an appropriate time, water flows into the shooting apparatus, and thus the shooting apparatus is easily rusted. To avoid tarnishing the components of the shooting game apparatus and keeping them clean, water removal must be carried out periodically. Thus, it takes much maintenance time and maintenance cost to remove the water from the shooting game apparatus.

Further, the conventional bullet feeding apparatus cannot rapidly feed a large number of bullets to the shooting apparatus because the capacity of the magazine storing the bullets is small. Further, the operation of the ammunition feed apparatus is unstable, and the ammunition feed apparatus is liable to malfunction because the mechanical mechanism of the conventional ammunition feed apparatus operates according to the on-off operation of the solenoid is very complicated. The cartridges are fed from the magazine to the shooting apparatus by means of compressed air, so that the path of the feed is long. Therefore, if there is a height difference between the position of the shooting apparatus and the position of the bullet feeding apparatus, the bullets cannot be smoothly delivered.

Further, the bullet used for the shooting game apparatus using compressed air is easily broken or broken, and thus the size of the bullet is smaller than a standard size. On the other hand, since the bullet hits the inner wall of the shooting apparatus or the target, the shape of the bullet, which is originally spherical, is deteriorated to become an ellipse having a very large difference from the standard shape. Conventional bullet feeding devices cannot distinguish between broken or broken bullets, thus creating a number of problems.

Furthermore, conventional shooting game apparatuses require many components, such as: a spool (spool) mounted within the firing apparatus for moving the cartridge; a solenoid for operating the spool; and a compressed air delivery pipe for delivering compressed air to the solenoid control valve, and therefore, the manufacturing cost of the shooting game apparatus is high. Further, since the mechanism of the conventional shooting game apparatus is complicated, the assembling work of the apparatus is difficult and the productivity is low. Further, the conventional shooting game apparatus is low in reliability because the electrically operated solenoid or the compressed air delivery pipe is liable to malfunction by mistake of a player or a user.

Best mode for carrying out the invention

The invention may be better understood by reference to the following description of various embodiments taken in conjunction with the accompanying drawings.

Fig. 1 is a schematic diagram of a shooting game apparatus according to the present invention.

As shown in fig. 1, the shooting game apparatus includes: a housing (not shown); an air compressor 10; at least one shooting device 50 for shooting the bullet using the compressed air supplied from the air compressor 10; a bullet firing pressure providing means 30 for supplying high-pressure compressed air to the firing apparatus 50 to fire the bullet; a bullet delivering pressure providing means 40 for applying low-pressure compressed air to the bullet to deliver it to the shooting apparatus 50; a pressure distribution valve 20 connected to the air compressor 10 and the high pressure pipe 80 for distributing the compressed air generated by the air compressor 50 to the bullet shooting pressure providing means 30 and the bullet delivering pressure providing means 40; and an air filter 60 disposed inside the high pressure pipe 80 for removing particles or foreign substances and moisture from the compressed air.

The bullet firing pressure providing means 30 is installed on a bullet firing pressure transfer pipe which connects the firing apparatus 50 with the pressure distribution valve 20. Further, the bullet firing pressure providing means 30 includes a bullet firing pressure regulating valve 31 and an auxiliary tank 35, and the auxiliary tank 35 is installed between the pressure distribution valve 20 and the firing device 50 for temporarily storing the compressed air distributed by the pressure distribution valve 20.

The bullet delivering pressure providing means 40 is installed on a bullet delivering pressure transmitting pipe 95, and the bullet delivering pressure transmitting pipe 95 connects the pressure distributing valve 20 with the firing equipment 50. The bullet delivering pressure providing means 40 includes: a pressure reducing valve 41; at least one bullet delivering pressure regulating valve 43 installed between the pressure reducing valve 41 and the firing equipment 50 for regulating the pressure reducing pressure of the compressed air; and a low pressure control valve 45 installed between the bullet delivering pressure regulating valve 43 and the shooting devices 50 for supplying compressed air to the selected shooting devices 50.

The air compressor 10, the firing device 50, the pressure distribution valve 20, the bullet firing pressure regulating valve 31, the pressure reducing valve 43, and the low pressure control valve 45 are all controlled by a controller, and are electrically connected to the controller (not shown).

The operating principle of the above-described shooting game apparatus will not be described in detail below.

The compressed air generated by the air compressor 10 passes through the air filter 60, and during the passage through the air filter, moisture and particles or impurities contained in the compressed air are removed. After the compressed air is dried and cleaned, the pressure distribution valve 20 distributes the compressed air to the bullet firing pressure transfer tube 90 and the bullet delivering pressure transfer tube 95.

The compressed air distributed to the bullet firing pressure transmission pipe 90 is temporarily stored in the auxiliary air tank 35 and then selectively sent to one of the firing devices 50 by the sub-projectile firing pressure regulating valve 31.

The pressure of the compressed air distributed to the bullet delivering pressure transmitting pipe 95 is reduced by the pressure reducing valve 41, and then, the bullet delivering pressure regulating valve 43 regulates it. The number of the bullet delivering pressure regulating valves 43 is the same as the number of the shooting devices. Further, the number of bullet delivering pressure regulating valves that are turned on is the same as the number of firing apparatuses 50 that are used. Therefore, the pressure sent from the bullet delivery pressure regulating valve 43 to each shooting device 50 is the same by regulation with the low-pressure control valve 45.

The bullet delivery pipe is connected to a bullet delivery pressure transfer pipe which connects the low pressure control valve 45 and the shooting apparatus 50 together, and the bullets are sent from the bullet delivery apparatus to the shooting apparatus 50 through the bullet delivery pressure transfer pipe 95.

The shooting game apparatus according to the present invention further includes a moisture drying device 70 for removing moisture generated from the air compressor 10.

The moisture drying device 70 includes: a steel container connected to one end of the moisture exhaust pipe 15; and a heat-radiating wire installed at the bottom of the steel container to discharge moisture through the moisture discharge pipe 15. However, the moisture drying device 70 is not limited to the steel container having the heat-radiating wire. A heating unit or a unit that can perform exothermic reaction may be used as the moisture drying device 70 such as a steel container having a heat-radiating wire.

Bullet feeding equipment

The shooting game apparatus according to the present invention further includes a bullet feeding apparatus connected to or fixed to the bullet delivering pressure transmitting tube 95 for feeding bullets to the shooting apparatus 50.

Fig. 2 is a perspective view of a feeder apparatus according to the present invention. The ammunition feeding device comprises: a rectangular bullet supply box 101 for storing a bullet B; and a bullet delivery portion 150. The unit indicated by a numeral is a support plate for supporting the magazine 101.

The magazine 101 has a discharge port 101a at the bottom of the magazine 101 to transfer the cartridge B in the magazine 101 from the magazine 101 to the cartridge transfer section 150 through the discharge port 101 a.

The bullet delivering part 150 is installed on the lower surface of the magazine 101. Figure 3 shows the bullet delivery portion 150 in detail. The bullet delivering section 150 includes: a plate 103 having a vertical hole 103a formed through the plate 103 and a guide groove 103b formed on a lower surface of the plate 103 and connected to one end of the vertical hole 103 a; a bullet feed shaft 102 provided at a lower portion of the plate 103; a driving device 110 connected to one end of the bullet delivering shaft 102 for rotating the bullet delivering shaft 102; a bullet delivering means 130 for forcing the bullet B delivered by the bullet delivering means 102 to be delivered to the shooting apparatus 50; and a compressed air supply device 140 for delivering compressed air to push the bullet toward the shooting apparatus 50.

A plate 103 is located between the magazine 101 and the cartridge feed shaft 102 for providing a passage for the cartridges B to be fed from the magazine 101 to the cartridge feed shaft 102. The vertical hole 103 is a cylinder that allows the bullet B to freely fall.

The vertical hole 103a communicates with the ejection outlet 101a of the magazine 101. Thus, the bullet B can move along the vertical hole 103a and the guide groove 103B.

The bullet delivery shaft 102 has a spiral groove 102a on an outer surface thereof, along which spiral groove 102a the bullet can pass.

The driving means 110 includes a motor M and a coupling 111, and the coupling 111 is connected between the motor M and the bullet delivering shaft 102 to rotate the bullet delivering shaft 102 by the motor M.

First and second support plates 104, 106 are attached to both sides of the plate 103 to fix it to the bullet delivery shaft 102. Further, the magazine 101 and the bullet delivering section 150 are fixed to each other by the support plates 104, 106. The second support plate 106 has a through hole 106a, and the bullet B passing through the guide groove 103B and the spiral groove 102a can be discharged to the outside of the bullet delivering shaft 102 through the through hole 106 a.

Further, the bullet delivering means 130 is a trajectory for delivering the bullet B from the second support plate 106 to the shooting apparatus 50. The bullet delivering device 130 includes: a fixed block having a bullet feeding hole 131a through which the bullet B can pass and a compressed air transfer hole 131B connected to the compressed air supply means 140; a first bullet delivering tube 132 having one end connected to the through hole 106 and the other end connected to the bullet delivering hole 131 a; and a second bullet delivering tube 133 of which one end is connected to the bullet delivering hole 131a and the other end is connected to the shooting apparatus 50.

Accordingly, the bullet B reaches the shooting apparatus 50 through the through-hole 106a formed on the second support plate 106, the first bullet-delivering tube 132, the bullet-delivering hole 131a formed on the fixed block, and the second bullet-delivering tube 133 along the spiral groove 102 a.

The compressed air supply device 140 includes: an air compressor (refer to a unit indicated by numeral 10 in fig. 1) for supplying compressed air; and an air delivery pipe 141 connected to an air compressor and delivering compressed air to the compressed air delivery hole 131 b. Thus, the compressed air is sent to the bullet delivery hole 131a, and the bullet B is delivered to the shooting apparatus 50. More specifically, the compressed air supply device 140 corresponds to the bullet delivering pressure transmitting tube 95.

It is preferable to form the magazine 101 to have a bottom tapered toward the center portion, so that it is easy to continuously feed the cartridges B to the cartridge conveying portion 150 through the ejection port 101 a.

The operation of the ammunition feed apparatus is explained below.

First, the cartridges B stored in the magazine 101 successively pass through the ejection port 101a and the vertical hole 103a formed in the bottom of the magazine 101, and then, after freely falling into the vertical hole 103a, enter the spiral groove 102a of the cartridge conveying shaft 102. The bullet delivering shaft 120 continuously rotates because the bullet delivering shaft 120 is connected to the motor M. Accordingly, the bullet inserted into the spiral groove 102a moves to the bullet delivering device 130 along the guide groove 103 b. The bullet B vibrates due to the rotation of the bullet delivering means 102 and rolls due to the frictional force of the wall surface of the spiral groove 102 a. Therefore, as shown in fig. 4a to 4c, the abnormal bullets B', B ″ deformed due to the breakage, chipping, or breaking fall down before reaching the right side of the bullet delivering device 102. Therefore, only normal bullets having a standard shape and size reach the bullet delivering device 130.

Thereafter, the normal bullet B passes through the through hole 106a and the first bullet delivering tube 103 communicating with the through hole 106 a.

The cartridges B are successively delivered from the magazine 101 to the cartridge delivery device 102 by gravity, and sorted by the cartridge delivery shaft 102 continuously rotated by the driving device 110 to force the sorted normal cartridges to the fixed block 131. The bullet feeding force from the magazine 101 to the through hole 106a is the rotational force of the motor M. However, the bullet delivering force from the fixed block 131 to the firing device 50 is the pressure of the compressed air.

That is, the compressed air supply means 140 is installed approximately at the center portion of the bullet delivering means 130 to force the bullets from the bullet feeding apparatus to the center portion between the bullet feeding apparatus 101 and the shooting apparatus 50 by the rotational force of the motor M, and thereafter, the bullets B are delivered from the center portion to the shooting apparatus 50 by the compressed air. Therefore, since the compressed air is used, the motor M is not overloaded, and the shot delivery time is shortened.

Further, the bullet delivering means 130 may be made of a pipe member connected to the compressed air supplying means at a central portion thereof.

Fig. 4a to 4c are side sectional views showing a discriminating operation for discriminating an abnormal bullet from sundries from the bullet delivering shaft. As shown in fig. 4a, the normal bullet B can move along the guide groove 103B. However, as shown in fig. 4B and 4c, the abnormal bullets B' and B "or sundries fall down. Like numbers in fig. 4a to 4c and fig. 3 denote like elements.

Bullet sorting device

The shooting game apparatus according to the present invention further comprises a bullet sorting apparatus for discriminating and removing abnormal bullets before feeding the bullets to the above-mentioned bullet feeding apparatus.

Fig. 5 is a perspective view of the bullet sorting apparatus according to the present invention. The bullet sorting apparatus 200 includes: a bullet queuing device 240 for queuing and receiving bullets B fired from a firing device (not shown); a bullet screening device 250 and a drive device 260.

The bullet queuing apparatus 240 includes a base plate 241, a queuing plate 243, and a guide plate 245. The floor 241 slopes downwardly toward the front so that the cartridges B can roll to the sloping side wall of the front edge. The floor 241 collects the belt-conveyed cartridges B. A queuing plate 243 is vertically mounted on the front surface of the base plate 241. A guide plate 245 contacts one end of the queuing plate 243 and is vertically installed on the bottom plate 241 for guiding the cartridge B forward to the front edge.

The spacing between queuing plate 243 and base plate 241 is greater than the diameter of cartridge B.

The bullet B rolls to the front because of gravity because the bottom plate 241 is formed to incline forward, the bullet B is lined up between the bottom plate 241 and the queuing plate 243, and then the bullet B is sent to the bullet screening device 250.

The bullet screening means 250 is disposed in parallel with the bullets B queued by the bottom plate 241 and the queuing plate 243. The bullet screening apparatus 250 includes: a first selector rod 251 having a spiral groove on an outer surface thereof; and a second selector rod 255 of cylindrical shape spaced from the first selector rod 251 by a distance equal to the diameter of the bullet B.

The bullet screening device 250 may divide the bullets into three groups: normal bullets, large bullets larger than normal bullets, and small bullets smaller than normal bullets.

That is, the first selector rod 251 shown in fig. 6 includes 3 regions divided according to the depth of the spiral groove 251 a: first to third regions AA, BB, CC. The first area AA is provided for screening out broken or fragmented small bullets B' having a size smaller than the normal size. A second zone BB is provided for selecting normal size bullets B and a third zone CC is provided for screening out particles or impurities or deformation-producing big bullets B ".

In the first area AA, the distance between the center portion of the spiral groove 251a formed on the first selector rod 251 and the second selector rod 255 is smaller than the diameter of the normal bullet B. First, all the cartridges B, B', B "received by the bottom plate 241 are sent to the first area AA, guided by the guide plate 245. Thus, the normal bullet B or the large bullet B ″ moves to the second zone BB along the spiral groove 251, and the crushed or ruptured small B' falls downward through the gap between the spiral groove 251a and the second selector rod 255.

On the other hand, in the second region BB, the depth of the spiral groove 251b of the first selector rod 251 is greater than the depth of the spiral groove 251 a. Therefore, the distance between the central portion of the spiral groove 251B in the second zone BB and the second selector rod is slightly larger than the diameter of the normal bullet B. Thus, the normal bullet B falls below the second zone BB and only the large bullet B "moves to the third zone CC. In the second zone BB, only the normal bullet B must fall. Therefore, the distance between the center portion of the spiral groove 251b in the second zone BB and the second selector rod must be precisely designed. For example, a normal size bullet has a diameter of 5.9-6mm, so the distance must be slightly greater than 6mm, but the tolerance cannot be large.

A third zone CC is provided for the selection of deformed big bullets. Therefore, in the third region CC, the depth of the spiral groove 251c of the first selector rod 251 is greater than the depth of the spiral groove 251b in the second region BB. Therefore, the distance between the central portion of the spiral groove 251c and the second selector rod is greater than that in the second region BB.

The bullets falling into the zones AA, BB, CC, respectively, must be collected separately, and a case is provided below the bullet sorting apparatus 200 of each zone. Further, it is preferable to install a bullet collecting portion (not shown) for feeding collected normal bullets to the shooting apparatus below the second zone BB.

The bullet collecting portion may be a case or a tray.

The operation of the bullet sorting apparatus 200 will be described below.

In the case where the player fires the bullets, the bullets B fired from the firing device are transferred to the bullet sorting device 200 by means of the transfer belt installed below the firing device, and then, the bullets freely fall onto the bottom plate 241 of the bullet sorting device 200.

The bullets B roll along the downwardly inclined bottom to the queuing plate 243 located in front of the bottom plate 241 and are sent to the first area AA. Then, the bullet moves to the second zone BB along the spiral groove 251 as the first selector rod 251 rotated by the driving means 260 rotates. The second selector rod 255 also rotatably contacts the cartridge entering the spiral groove 251 a. At this time, as shown in fig. 7a, the small bullet B' falls into the first zone AA, and the normal bullet B or the large bullet B ″ moves to the second zone BB along the spiral groove 251 a. Then, as shown in fig. 7B, the bullet B, B "is inserted into the spiral groove 251B, and the normal bullet B falls into the second zone BB, and the large bullet B" moves along the spiral groove 251B to the third zone CC. The normal bullets B falling into the second zone BB are collected by a bullet collecting section (not shown) and sent to a bullet feeding apparatus for feeding them to a shooting apparatus.

In the preferred embodiment of the present invention, the bullet-selected area is divided into 3 areas, but the present invention is not limited to this preferred embodiment, and can be modified, changed and altered in many different ways.

Motor overload protection device

The shooting game apparatus according to the present invention includes a motor overload protection apparatus which can protect the motor from being damaged when the motor cannot rotate because particles or sundries are caught in a gap between the first selector bar 251 and the second selector bar 255 of the bullet sorting apparatus 200.

Fig. 8 is a perspective view of a motor overload protection apparatus. The motor overload protection apparatus includes: a first coupling 301a mounted on a driving shaft 301a for transmitting a rotational force of the motor; a second coupling 303 mounted on the output shaft 304; a force transmission means 310 for transmitting a rotational force from the first coupling 302 to the second coupling 303.

The first coupling 302 has an insertion hole 321 at a front portion so that the force transmission device 310 is inserted into the insertion hole 321 for reverse or forward rotation.

The force transmission device 310 includes an elastic member 311 inserted into the insertion hole 321, and a ball 312 provided on the elastic member 311 and movable in reverse and forward directions.

The second coupling 303 has ball insertion holes 331 at a side surface contacting the first coupling 302.

The first coupling 302 has a plurality of insertion holes 321, for example, 4 insertion holes, in a front face portion, wherein each insertion hole 321 is formed radially.

The elastic member 311 is a typical spring. In a preferred embodiment of the present invention, a compressed coil spring is used as the elastic member 311.

The insertion hole 321 must be formed to have an entrance portion smaller than the diameter of the ball 312 so that the ball 312 and the elastic member 311 are not separated by the insertion hole 321. In a preferred embodiment of the present invention, a ring having an inner diameter smaller than that of the balls 312 is fixed to an inlet portion of the insertion hole 321. Thus, the entrance portion of the insertion hole 321 is smaller than the diameter of the ball 312. However, the entrance size of the insertion hole may be reduced in any other known manner.

However, the inner diameter of the ring 313 is preferably just slightly smaller than the diameter of the balls 312. Thus, when the balls 312 are placed in the insertion holes 321, a portion of the balls 312 may be exposed to the outside.

Further, the thickness of the ring 313 preferably must be sufficiently thin, and the side of the ring 313 is flat. Further, the insertion hole 321 has a fitting groove at a side surface. The depth of the fitting groove is the same as the thickness of the ring 313 so that the side of the first coupling 302 is flat after the ring 313 is fitted into the fitting groove.

As for the ring for reducing the entrance size of the insertion hole 321, the present invention is not limited to such a ring. Bolts or other attachment means may be used instead of such a ring.

For the force transmission device 310, the balls 312 are placed on the elastic member 311 and exposed to the outside of the first coupling 302. Further, part of the balls 312 enter the ball insertion holes 331 of the second coupling 303. In this case, the first coupling 302 and the second coupling 303 are coupled to each other, and the rotational force of the motor can be transmitted to the second coupling 303. If an external force is applied to the second coupling 303, the elastic member 311 is compressed by the ball 312 and is completely pressed into the insertion hole 321.

Therefore, the mechanical properties of the elastic member 311, such as elastic limit, fatigue limit, and hardness, are very important.

The operation of the overload protection apparatus for a motor according to the present invention will be described below.

Fig. 9a is a cross-sectional view of the overload protection apparatus for a motor in which a first coupling 302 and a second coupling 303 are combined with each other. Fig. 9b shows the situation when only the first coupling is rotating.

As shown in fig. 9a and 9b, the driving shaft 301a to be rotated by the motor 301 is installed in the first coupling 302, and the first coupling 302 is combined with the second coupling 303 so that the balls 312 are elastically supported by the elastic members 311 and the balls 312 are inserted into the insertion holes 331 of the second coupling 303. Thereafter, the motor rotates. During the rotation of the motor, the balls 312 transmit the rotational force of the first coupling 302 to the second coupling 303, so that the first coupling 302 can rotate together with the second coupling 303, and the output shaft 304 combined with the second coupling 303 also rotates.

However, if an external force is applied to the second coupling 303, the second coupling 303 stops rotating while the first coupling 302 continues to rotate because the motor connected to the first coupling 302 continues to rotate. At this time, the balls 312 inserted into the insertion holes 331 rotate together with the first coupling 302. Therefore, if the second coupling 303 stops rotating, the balls 312 are still rolling and pushed toward the elastic member 311, so that the balls 312 are separated from the insertion holes 331 of the second coupling 303 and are completely inserted into the insertion holes 321 of the first coupling 302, as shown in fig. 9 b. Thus, the connection of the first coupling 302 to the second coupling 303 is released so that the first coupling 302 can continue to rotate independently of the second coupling 303. Therefore, the motor can be prevented from being overloaded and damaged.

Shooting device

Fig. 10 and 11 show the internal structure of the shooting apparatus, in which fig. 10 shows a trigger-not-pulled condition, and fig. 11 shows a trigger-pulled condition.

At the same time, the advancing part 475 advances the bullet entered into the bullet case 463 to the bullet shooting pipe 465, and ejects the bullet from the shooting apparatus 50 by the compressed air supplied through the bullet shooting pressure transmitting pipe.

If the player releases the trigger 470, the detection part 473 inserts into the sensor 467, and the sensor 467 detects the movement of the trigger 470 and transmits the detection signal to the controller. The detection signal closes the switching valve 455. At the same time, the propelling part 475 is moved from the bullet shooting pipe 465 toward the side of the bullet box 463 to push up the bullet B with the low-pressure compressed air supplied through the bullet delivering pressure transmitting pipe 95 so that the bullet B is in a standby position waiting for the firing. The on-off valve 445 is continuously opened when the game progresses halfway, and the on-off valve 445 is closed during maintenance or replacement of the shooting game apparatus.
