This serves to improve the propulsion force by the wing when the toy is manufactured by mounting the wing to the movable column, or to efficiently distribute the force to be used. That is, when the wing is coupled to the movable column minimizes the air resistance during the ascending movement of the wing, in the downward movement serves to push the air backward to further improve the driving force.

11A to 11D are explanatory diagrams showing a part of another compressed air engine and an operation process thereof according to the present invention, and the structure thereof will be briefly described below.

The through-hole 211a is formed at the lower portion so as to be directly coupled to the compressed air providing unit (for example, the compressed air storage unit 140) so that the compressed air can be provided, and two through-holes at the upper portion so that the compressed air can escape. 211b and 211c are formed to form the air injection unit 210. In addition, the air injection unit 210 has one ball 213 having a diameter of a size capable of blocking the through holes (211a ~ 211c) in the space through which the compressed air passes.

In addition, the upper portion of the air injection portion 210 is coupled to the cylinder portion 220 communicated with the two through holes (211b, 211c).

The cylinder portion 220 is composed of two cylinders 221 different from the cylinder portion illustrated in FIGS. 1 to 4c, and the piston 223 having an O-ring 224 fitted therein. ) Is combined. Of course, the O-ring 224 is smaller than the diameter inside the cylinder 221.

In addition, the piston 223 has all the features of the pistons exemplified in FIGS. 1 to 4C, and may not merely form a protruding bar at the bottom of the piston. However, the present invention is not limited thereto, and the piston may be coupled to the bar and a spring may be coupled to the bar. Of course, the through-hole 221a is formed on the sidewall of the cylinder 221 is also the same.

As shown in FIG. 12, the toy vehicle FL according to the present invention uses the above-described compressed air engine EG as it is, and the wing 500 is mounted on the movable column 340 of the compressed air engine EG. More combined. In the drawings, reference numerals denote heads 510 and tails 520 coupled to the front and rear of the compressed air engine EG, which serve to uniformly distribute the overall weight.

The wing 500 is a thin synthetic resin, for example, a thin plastic film is molded using a high-temperature mold, and the cross-section is formed in a number of wavy shapes to secure the rigidity. That is, as shown in Fig. 13A, the front end (I-I line) of the region most closely attached to the compressed air engine EG is curved from the top to the bottom, and the rear end is curved from the top to the bottom. . In addition, as shown in Fig. 13B, the middle region (line II-II) is curved from the top to the bottom (having a much gentler angle than from Fig. 13A), and the rear end is curved from the bottom to the top, Finally, as shown in Fig. 13C, the end region (line III-III) is curved in the leading end from the bottom to the top, and the rear end is the curved line from the top to the bottom.

In addition, when viewed from the top surface of the corrugated bone is preferably formed so as to be curved toward the rear end from the front end away from the compressed air engine.

As described above, the wing of the cross section is wavy or concave (concave), the lift is generated when the linear movement, the lifting and thrust is generated strongly during the churning movement, and the wavy bone is curved curved from the front end to the rear end. Therefore, the air friction with the wing during the churning movement of the wing is naturally pushed toward the rear end of the wing, so that the lift and thrust occurs more strongly.

In addition, since the movable column is coupled only to the tip of the wing, the movable column is first reciprocated up and down during the up and down movement of the wing, and the rear end of the wing moves along the back, so that the wing is naturally inclined, Therefore, the lifting and thrust generation are performed more efficiently.

Further, as shown in FIGS. 13A to 13C, the stiffness of the wing can be further increased by adding a certain thickness of carbon graphite, epoxy, or synthetic resin (stiffness increasing means 501) to the tip of the wing 500. have.

On the other hand, as in the toy vehicle (FL ', FL ") shown in Figures 14 and 15 may be mounted a plurality of wings 500. This is the compressed air engine (EG') described in Figures 6-11d. It is possible structure when adopted.

Meanwhile, as illustrated in FIGS. 16A through 16C, the fixed blade 502 may be further attached to the tail portion 520 of the toy vehicle. By the fixed wing 502, the toy vehicle can adjust the direction up, down, left, right. For example, when the rear ends of the fixed blades 502 formed on both sides of the tail portion 520 face downward as shown in FIG. 16B, the toy vehicle descends (the tail portion 502 rises) The whole vehicle is lowered, the direction of movement is opposite to the general toy vehicle), the toy vehicle is raised when the rear end of the fixed blade 502 is upward (tail part 520 is lowered, so the toy vehicle The whole is raised, the direction of movement is reversed from the normal toy vehicle). It can be seen that the action of the fixed wing 502 as opposed to the movement of the normal toy vehicle, because the lift and thrust is caused by the wing swinging up and down.

In addition, in the toy vehicle FL ', the compression engine EG' and the wing 500 are approximately -70 to the head 510 and the tail 520 (collectively referred to as a body), as shown in FIG. It can be combined with an inclination angle of 70 °. By being coupled with a certain angle as described above, the toy vehicle (FL ') can obtain a stronger lift and thrust, and can also fly in a state in which the toy vehicle is stationary in the air at an appropriate coupling angle. Therefore, it can be seen that various flight movements are possible by properly adjusting the coupling angle of the compression engine.

Referring to the operation and operation of the compression engine (EG) and toy vehicle (FL) having such a structure is as follows.

First, it is assumed that there is no air in the compressed air storage unit 140, and the process and operation of filling the compressed air storage unit 140 with air will be described.

2 and 3, air is injected by combining compressed air providing means such as a pump to the communication hole 211 formed at the bottom of the air injection unit 210. Then, since the diameter of the ball 213 coupled to the communication hole 211 is smaller than the diameter of the communication hole 211 moves toward the upper portion of the communication hole 211. At this time, by artificially moving the end of the movable column 340 to inject compressed air with the bar 229 protruded to the lower portion of the piston 223 raised properly so as not to be inserted into the communication hole 211, the ball 213 ) Blocks the upper end of the communication hole 211, so that the compressed air not only pushes the piston 223 upwards but also does not exit the outside of the cylinder 221, and thus, the compressed air is injected into the air inlet 210. Exit through the communication hole 212 formed toward the side of). The compressed air is then introduced into the communication hole 121 formed in the second compressed air transmission unit 120 through the communication hole 111 formed in the first compressed air transmission unit 110. In addition, the introduced air is stored in the compressed air storage unit 140 along the recess line 133 formed in the bar 132 of the compressed air adjusting unit 130.

Of course, in this case, the compressed air adjusting unit 130 is a state in which the cam 403, which is a component of the movement direction control unit 400 on one side, is pushed to the maximum by the spring 402, so that the cam 403 is It is moved to the compressed air storage 140 toward the maximum. Therefore, the air flows toward the compressed air storage unit 140 along the recessed line 133 portion deepest formed in the bar 130 of the compressed air adjusting unit 130.

If the compressed air continues to be stored as described above, the pressure of the compressed air storage unit 140 gradually increases, and accordingly, the compressed air adjusting unit 130 is gradually moved to one side. That is, in FIG. 3, as the pressure of the compressed air storage 140 increases, the packing 131 of the compressed air control unit 130 coupled to the second compressed air delivery unit 120 moves to the left. Accordingly, the cam 403 of the movement direction control unit 400 also overcomes the elastic force of the spring 402 and gradually moves to the left side.

In addition, the air is injected along the recess line 133 shallowly formed in the bar 132 of the compressed air adjusting unit 130, and eventually, the air is not easily injected by the high pressure.

Meanwhile, the process of providing the compressed air from the compressed air storage unit 140 to the air injection unit 210 of the power providing unit 200 is performed in reverse.

That is, the air from the compressed air storage unit 140 passes through the recess line 133 formed in the bar 132 of the compressed air adjusting unit 130, and then the communication hole (2) of the second compressed air delivery unit 120. Through 121 reaches the communication hole 111 of the first compressed air transmission unit 110. Subsequently, the compressed air is moved through the communication hole 111 formed in the first compressed air delivery unit 110 and is finally injected into the communication hole 212 formed on the side of the air injection unit 210.

If the compressed air is continuously provided as described above, the pressure of the compressed air storage unit 140 gradually decreases. In this case, the cam 403 is gradually compressed air by the restoring force of the spring 402 of the movement direction control unit 400. The packing 131 of the adjusting unit 130 is pushed toward the compressed air storage 140. Then, the compressed air is discharged along the recess line 133 which is formed relatively deep in the bar 132 of the compressed air adjusting unit 130. Therefore, as the pressure of the compressed air storing unit 140 gradually decreases, the amount of air is increased. Will be provided. In this way, the air is provided at a high pressure instead of a small amount at the beginning, and the air at a low pressure is provided instead of a large amount, so that a relatively uniform amount or a uniform pressure is maintained during the entire operation of the engine EG. To provide air.

On the other hand, when the engine (EG) is operated by the compressed air from the compressed air storage unit 140 will be described as follows.

First, when compressed air is provided through the communication hole 212 formed on the side of the air injection unit 210 of the power providing unit 200, the compressed air is compressed into the communication hole 211 formed above and below the air injection unit 210. Air is provided. Then, the two balls 213 located in the upper and lower communication holes 211 are moved to the upper and lower, respectively. The ball 213 moved to the bottom blocks the lower portion of the communication hole 211 and thus the compressed air moves only to the top.

The compressed air and the ball 213 toward the upper side push the lower portion of the piston 223 at the same time, the step 222 of a predetermined depth is formed on the bottom surface of the cylinder 221 to further strengthen the lower portion of the piston 223 Pushed.

That is, in the absence of the step 222, the compressed air is directed toward the inner wall of the cylinder 221, and the diameter of the O-ring 224 surrounding the piston 223 is smaller than the inner diameter of the cylinder 221. Therefore, it is easy for all the air to escape to the outside of the cylinder 221 through the gap, and the step 222 formed on the bottom surface of the cylinder 221 suppresses this defect. In other words, a space of a predetermined size is secured by the step 222 between the piston 223 and the bottom surface of the cylinder 221, so that a certain amount of compressed air can strongly push the bottom surface of the piston.

In addition, a partition wall 225 is formed at the lower portion of the piston 223 to form two space parts (upper and lower part), and a plurality of communication holes 226 are formed in the partition wall 225. The compressed air is raised to the space portion of the upper part of the partition wall 225 through the communication hole 226.

This elevated compressed air then tries to escape out of the piston 223 through a plurality of communication holes 226 formed in the sidewalls of the piston 223. On the other hand, since the O-ring 224 is formed on the outer periphery of the communication hole 226 formed on the side wall of the piston 223, the compressed air is such that the O-ring 224 is in close contact with the inner wall of the cylinder 221 Push it out. Therefore, the compressed air uniformly pushes up the entire piston 223 to the top without exiting the inner wall of the cylinder 221.

When the piston 223 is raised, the auxiliary body 320 is coupled to the main body 310 of the power converter 300 above the piston 223, the auxiliary body 320 is moved upwards. Done.

That is, the bar 323 is coupled to the auxiliary body 320 by a spring 322, and the bar 323 is in contact with the upper portion of the piston 223, so that the upward movement of the piston 223 is performed. By this, the spring 322 is moved upward while overcoming the elastic force.

In addition, an H-shaped block 330 is coupled to the auxiliary body 320, and one end of the movable column 340 is coupled to the H-shaped block 330 by a roller 331. In addition, since the other side of the movable column 340 is rotatably coupled to the protrusion 312 of the main body 310, the movable column 340 is rotated at a predetermined angle about the pin. You exercise. That is, the end of the movable column 340 is lowered to the bottom.

Subsequently, when the piston 223 rises above a predetermined position, that is, when the piston 223 rises above the position where the communication hole 221a is formed on the wall of the cylinder 221, the compressed air pushing the piston 223 upwards is removed. Out through the communication hole 221a. Then, the inner pressure of the cylinder 221 below the piston 223 drops rapidly to atmospheric pressure, and also by the restoring force of the spring 322 formed on the bar 323 of the auxiliary body 320 of the power providing unit 200. The auxiliary body 320 and the piston 223 is suddenly lowered down. Therefore, the movable column 340 rises upwards as opposed to the above.

In addition, when the piston 223 descends, a plurality of groove lines 228 are formed in the circumference of the piston 223 in the longitudinal direction, so that air inside the cylinder 221 along the groove lines 228 is formed. Escape easily.

When the piston 223 is completely lowered as described above, the bar 229 formed in the lower portion of the piston 223 to the upper ball 213 that was blocking the communication hole 211 of the air injection unit 210. Push it down. Then, as described above, the compressed air pushes the piston 223 upward again and repeats the operation as described above.

On the other hand, the operation of the movement direction control unit 400 coupled to the back of the power providing unit 200 will be described as follows. (See FIGS. 2, 3, 6) The cam of the movement direction control unit 400 ( A plurality of grooves are formed in the 403, and a plurality of rollers 404 protruding outwardly are coupled to the grooves at regular or irregular intervals.

The cam 403 initially overcomes the elastic force of the spring 402, the packing 131 of the compressed air control unit 130 is moved to the left by the pressure provided from the compressed air storage unit 140, the cam 403 is also moved to the left as far as possible.

On the other hand, if the air is continuously consumed from the compressed air storage unit 140, the pressure acting on the compressed air control unit 130 is gradually reduced, and thus the cam by the restoring force of the spring 402 coupled to the cam 403 403 gradually moves to the right. Of course, at this time, the compressed air control unit 130 coupled to the second compressed air delivery unit 120 is also moved to the right by the movement of the cam 403.

A plurality of protruding rollers 404 are coupled to the cam 403, and the cam 403 is coupled to the through hole 332 of the H-shaped block 330, so that the cam 403 moves to the right. As the contact position of the roller 404 and the H-shaped block 330 of the cam 403 is changed. That is, although the cam 403 moves in a straight direction, the position of the H-shaped block 330 itself is changed because the H-shaped block 330 can move left and right to some extent inside the auxiliary body 320.

Then, because the movable column 340 is coupled to the H-shaped block 330, the force action point of the movable column 340 is slightly changed, so that the stirring motion of each of the pair of movable cylinders 340 is performed. It is performed asymmetrically. Therefore, in the toy vehicle FL with the wing 500 on the movable column 340, the flight path is determined by the movement direction control unit 400. In other words, the flight path is adjusted depending on how the roller 404 is coupled to the cam 403 of the movement direction control unit 400.

6 to 10 and 14, the operation of another compressed air engine of the present invention will be described. Here, since the action of the other toy vehicle (FL ', FL ") of the present invention has been described above it will be omitted.

First, a predetermined amount of compressed air is provided from the air injection unit 210 through a through hole formed at the side of the air injection unit 210 of the power providing unit 200.

Then, the air flowing through the outer walls of the two air guide protrusions 215 formed in the air injection unit 210 is collected at the center, and then again formed through the inner wall of the protrusion 215 at the distal end of the protrusion 215. Flows up to (216). Subsequently, the compressed air pushes up any one of the balls 213 coupled to the two through holes 216 and moves toward the upper cylinder 221. This can also be achieved by artificially moving a pair of wings of the toy vehicle.

The compressed air and the ball 213 toward the upper side push the lower part of the piston 223 at the same time, the step 222 of a predetermined depth is formed on the bottom surface of the cylinder 221 to further strengthen the lower part of the piston 223 Pushed.

Here, since the operation of the O-ring 224 and the like coupled to the step 222 and the piston 223 has been described above, a detailed description of the operation is omitted.

When the piston 223 is raised, since the H-shaped block 330 is positioned above the piston 223, the H-shaped block 330 is moved upward.

That is, the bar 333 is coupled to the lower portion of the H-shaped block 330, the bar 333 is in contact with the upper portion of the piston 223, by the upward movement of the piston 223, The H-shaped block 330 is moved upward.

In addition, one end of the movable column 340 is coupled to the H-shaped block 330 by a roller 331. In addition, since the other side of the movable column 340 is rotatably coupled to the protrusion 312 of the main body 310, the movable column 340 is rotated at a predetermined angle about the pin. You exercise. That is, the end of the movable column 340 is lowered to the bottom.

Subsequently, when the piston 223 rises above a predetermined position, that is, when the piston 223 rises above the position where the communication hole 221a is formed on the wall of the cylinder 221, the compressed air pushing the piston 223 upwards is removed. Out through the communication hole 221a. Then, the pressure inside the cylinder 221 under the piston 223 drops sharply to atmospheric pressure, and thus, the H-shaped block 330 and the piston 223 rapidly descend to the bottom. Therefore, the movable column 340 rises upwards as opposed to the above.

Meanwhile, another H-shaped block 330 is coupled to the H-shaped block 330 by a connecting bar 339. Therefore, when the H-shaped block 330 of one side is raised, the H-shaped block 330 of the other side is lowered. Similarly, the two pistons also cross and reciprocate. As a result, each wing coupled to the two H-shaped blocks 330 crosses each other, which means that they move upward and downward.

Subsequently, when the piston 223 on one side is completely lowered, a ball 229 and a spring 230 formed at the lower portion of the piston 223 block the through hole 215 of the air inlet 210. Push (213) down. Then, as described above, the compressed air pushes the piston 223 upward again and repeats the operation as described above.

In addition, as another embodiment of the present invention will be described by reference to the operation of the power providing unit shown in Figs.

First, when compressed air is provided along the through hole 211a of the air injection unit 210, the air escapes through the through holes 211b and 211c formed in the upper portion of the air injection unit 210. At this time, if the air pressure is low in any one of the through holes 211b and 211c, the ball 213 moves to the through hole (for example, the through hole 211b), thereby blocking the through hole 211b. 11b)

Then, since compressed air continues to flow into the cylinder 221 communicating with the through-hole 211c, the piston 223 coupled thereto is raised upward. When the piston 223 rises above a predetermined height as described above, the compressed air is drawn out through the through hole 221a formed in the side wall of the cylinder 221. Then, the air pressure of the cylinder 221 drops rapidly, so that the ball 213 blocking the through-hole 211b moves toward the other through-hole 211c to block the through-hole 211c (see Fig. 11C).

Then, this time, the piston of the cylinder communicated with the through-hole 211c stops, and the piston of the cylinder communicated with the other through-hole 211b rises, and this operation is repeated repeatedly.

As described above, although the present invention has been described with reference to the above embodiments, the present invention is not limited thereto, and various modified embodiments may be possible without departing from the scope and spirit of the present invention. That is, in the present invention, the application example of the compressed air engine is described as being limited to the toy vehicle flying by the whipping motion of the blade, but not applicable only to this, it is applicable to all that require a constant driving force.

Therefore, according to the compression engine and the toy vehicle using the same according to the present invention, it is possible to artificially store a certain amount of compressed air in the compressed air storage unit, and also, by using the stored compressed air efficiently, the air injection unit and the cylinder unit By operating the power supply unit and appropriately converting the up and down reciprocating motion force provided by the power supply unit to change the rotational (whisting) motion force of a limited angle, it is possible to obtain power using pure compressed air.

In addition, by using the compression engine to move the wings up and down by the power of the repetitive churning motion within a limited angle, it is possible to implement the toy aircraft as insects or birds.

In addition, by forming the inclined groove line on the bar of the compressed air control unit, the output is kept constant during the entire operation of the compression engine.

In addition, by adding a plurality of rollers to the cam of the movement direction control unit can not only change the movement state of the power conversion unit of the compression engine, but also when applied to the toy vehicle has the effect of adjusting the flight path.

In addition, the O-ring installed in the piston is in close contact with the inner wall of the cylinder when the compressed air is provided, and when the compressed air exits from the inner wall of the cylinder, the up and down reciprocating motion of the piston is very effective.

In addition, since the movable liquor to which the wings are attached is coupled with the pins in the main body, the wing and the movable liquor may be stored in a state in which the wing and the movable liquor are removed from the main body during logistics movement, thereby reducing the logistics cost.

In addition, since the wing is formed in a plurality of corrugated cross-section, and the corrugated bone is curved toward the rear end of the wing from the start point to the end, it generates the lift and thrust very efficiently during the churning movement of the wing. It works.
