Multi-stage propulsion type toy rocket}

The present invention relates to a multi-stage propulsion type flight rocket toy, and more particularly, to a multi-stage propulsion type flight rocket toy capable of flying a vehicle higher and farther in the air for a long time by providing a continuous propulsion force over multiple stages.

In recent years, more and more families enjoy various hobbies together using their weekend leisure time. In particular, the number of toys that parents and children can enjoy together is increasing, and the development of toys that provide new structures and attractions is continuing. In addition, due to the increase of materials that are light, durable and inexpensive due to mass production, and the development of plastic materials that have significantly increased strength through R&D, demand for toy aircraft with a low burden on the general public is increasing. Examples include toys such as toy cars, helicopters, quadcopters, airplanes, and flying rockets.

In particular, the flight rocket is mainly used as a teaching tool for students to learn scientific principles in schools. In general, a toy flight rocket is launched into the air by the momentarily discharged air pressure and flies in an air current, and then freely falls to the ground when the propulsion is exhausted, and the related technology is Korean Patent Laid-Open No. 10-2011-0046623.

It comprises a tube of a certain diameter that is coupled to the groove.

Through this configuration, the learning air rocket launches the rocket by applying the same pressure to the air compressor while varying the positions of the center of gravity and the fixing plate from the front to the rear of the rocket body to fly according to the center of gravity of the rocket. It has the advantage of providing the effect of learning the scientific principles by measuring the distance, but because the rocket flies in the air only with the propulsion of compressed air through the pressure applied to the air compressor, sufficient flight time of the rocket is secured. It was difficult, and as a result, there was a problem that interest in the learning process using the conventional learning aerorocket remarkably declined.

The flight rocket toy according to the present invention is largely mounted on the launch pad 10 and the launch pad 10, as shown in FIGS. 1 to 2, and a rocket unit 20 that is launched into the air according to the operation of the launch pad 10 , One end is connected to the rocket unit 20 and the other end is mounted on the wire 40 and the rocket unit 20 fixed to the launch pad 10, but separated from the rocket unit 20 in the air and glides It can be defined as including (30).

The flight rocket toy according to the present invention is capable of flying the aircraft 30 higher and further in the air for a long time by providing the propulsion force for flying the aircraft 30 in the air in stages.

When the rocket unit 20 is launched by receiving first-stage propulsion through the launch pad 10, the rocket unit 20 assembly AS on which the vehicle 30 is mounted rises into the air. At this time, the rocket unit 20 rises in the air only to a height corresponding to the length of the wire 40, and when the rocket unit 20 assembly AS reaches a height corresponding to the length of the wire 40, the launch pad 10 ) By the wire 40 fixed to the release pin 23 of the rocket unit 20 is pulled in a direction opposite to the traveling direction. At this time, the vehicle 30 is separated while sliding from the rocket unit 20 by receiving the secondary propulsion force on the rocket unit 20 without resistance and soaring into the air, and the vehicle 30 separated from the rocket unit 20 is selectively When the energy is exhausted while flying while riding in the air current with the third thrust provided, it slowly freely falls to the ground and lands.

In this way, the flight rocket toy according to the present invention for providing continuous propulsion to the aircraft 30 has the following detailed configuration.

First, the launch pad 10 plays a role of injecting compressed air into the rocket unit 20 in order to launch the rocket unit 20 assembly AS into the air, and as an example, a support supported on the ground ( 11), including an injection pipe 12 installed vertically upright on the support 11, a soft air pump 13, and a connection hose 14 communicating the injection pipe 12 and the air pump 13 Illustrative of the launch pad (10).

When the user compresses the air pump 13, the compressed air generated inside the air pump 13 has a fluid flow structure that is supplied to the injection pipe 12 through the connection hose 14, and the rocket unit 20 It is mounted in the outer diameter of the injection tube 12 and is launched into the air by compressed air supplied to the injection tube 12.

If necessary, the launch angle of the rocket unit 20 may be changed by adjusting the angle formed by the injection pipe 12 on the support 11.

The compressed air provided from the launch pad 10 is used as a first-stage propulsion force for the aircraft 30 to fly into the air.

The launch pad 10 may be variously modified within a range capable of launching the rocket unit 20 into the air, and may further include components according thereto.

Next, the rocket unit 20 launches the aircraft 30 into the air with the first-stage propulsion provided from the launch pad 10, but reaches the height corresponding to the length of the wire 40 to the ground by the wire 40 Will be pulled. The moment the release pin 23 of the rocket unit 20 is pulled by the wire 40 provides a two-stage propulsion toward the aircraft 30 so that the aircraft 30 is separated from the rocket unit 20.

To this end, the rocket unit 20 is installed outside the rocket body 21, the rocket body 21, mounted on the launch pad 10, as shown in Figs. 2 to 4, and the flight body 30 slides The propulsion cradle 22 on which the rail 22a to be mounted possible is provided, and one end of the wire 40 is connected to the other side by the wire 40 while being mounted on the other side of the propulsion cradle 22 A release pin 23 that is disposed from the inside of the propulsion cradle 22 to one side of the release pin 23 to rotate and extend in the direction of the release pin 23 to contact the release pin 23 1 The operating cam 24 provided with a support protrusion 24a and a second support protrusion 24b extending and protruding toward the inside of the rail 22a to limit the sliding of the aircraft 30, the operation cam 24 A first elastic spring 25 that elastically presses in one direction, a second elastic spring 26 installed on the outer circumferential surface of the release pin 23 to elastically press the release pin 23 in the direction of the first support protrusion 24a ) And the release pin 23 is pulled to the other side, and the operation cam 24 rotates in one direction according to the elastic pressure of the first elastic spring 25, so that the second support protrusion 24b moves the rail 22a. When opened, it may be defined as including a propulsion means 27 that slides the aircraft 30 along the rail 22a and separates it from the propulsion cradle 22.

The rocket body 21 may be formed in the form of a circular pipe with one end closed and an empty inside, and is fitted into the outer diameter of the injection pipe 12.

The propulsion cradle 22 is made in the form of a bracket divided into two pairs, and is mounted and fixed on the outer surface of the intermediate point of the rocket body 21.

The rail 22a formed on the propulsion cradle 22 is formed to extend parallel to the longitudinal direction of the rocket body 21, and the aircraft 30 is slidably mounted on the rail 22a.

When the vehicle 30 is separated from the propulsion cradle 22, it slides in a straight line along the rail 22a and then separates, so that straightness can be secured without losing directionality in the air.

The release pin 23 is linearly reciprocated by a predetermined distance from the other side of the propulsion cradle 22, and the reciprocating movement of the release pin 23 is a traction force due to the pulling of the wire 40 and a release pin in a direction opposite to the traction force. It is achieved by the elastic pressing force of the second elastic spring (26) to move (23).

The operating cam 24 interlocks with the reciprocating movement of the release pin 23 and rotates in place to regulate the restraint of the aircraft 30 mounted on the rail 22a.

4, when the first support protrusion 24a of the operating cam 24 is in contact with the release pin 23, the second support protrusion 24b protrudes into the interior of the rail 22a (30) is in a state of being constrained so that it cannot be separated from the propulsion cradle (22).

On the other hand, as shown in Fig. 6, when the release pin 23 is pulled by the wire 40 in a direction opposite to the launch direction of the rocket unit 20, the release pin 23 and the first support protrusion 24a As the contact is released, the operation cam 24 is elastically pressed by the first elastic spring 25 and rotates in one direction to open the rail 22a. In this case, there is a requirement that the aircraft 30 can be separated from the propulsion cradle 22 by sliding along the rail 22a.

Next, the propulsion means 27 plays a role of separating the aircraft 30 from the propulsion cradle 22 by sliding the aircraft 30 equipped with the requirements that can be separated on the propulsion cradle 22 along the rail 22a.

Here, the propulsion force provided by the propulsion means 27 is used as a two-stage propulsion force to blow the aircraft 30 into the air.

As an example, the propulsion means 27 is bent to one side of the propulsion cradle 22 and is spaced apart from a fixture 27a mounted on the rocket body 21, and the fixture 27a and the aircraft 30 are mutually bent. It may be illustrated as including an elastic band (27b) for elastically pulling the flight body 30 in one direction.

The elastic band (27b) is mutually bending the air vehicle (30) and the fixture (27a) restrained on the rail (22a) by the second support protrusion (24b), and then the operating cam (24) rotates to the second support protrusion When (24b) releases the restraint of the aircraft 30, the tension of the elastic band 27b is released, and at the same time, the elastic band 27b is restored toward the fixing table 27a by the elastic restoring force, thereby reducing the second-stage propulsion force to the aircraft 30 It will be approved as.

In other words, the aircraft 30 is to fly in the air while obtaining a two-stage propulsion force through the propulsion means 27 and moving relative to the rocket unit 20.

On the other hand, as shown in FIG. 8A, a guide protrusion 22b for guiding the elastic band 27b to the outside of the propulsion cradle 22 may protrude from one side of the propulsion cradle 22.

The guide protrusion (22b) extends the elastic band (27b) to the outside so that it is not inserted into the inside of the rail (22a) when the elastic band (27b) that is bent on the fixture (27a) and the aircraft (30) is stretched or elastically restored. Responsible for a function, and if the elastic band (27b) is inserted into the inside of the rail (22a) during the operation of the elastic band (27b) as shown in Figure 8b, interference between the elastic band (27b) and the aircraft (30) This may occur or the elastic restoration of the elastic band 27b itself may become impossible.

When the elastic band (27b) is bent on the flight body (30), it is preferable to sufficiently open the space between the elastic bands (27b) to seat on the guide protrusion (22b). In addition, as shown in the enlarged drawing in FIG. 8A, a height difference h is formed between the fixing table 27a and the rail 22a to prevent the flight vehicle 30 separated from the rail 22a from colliding with the fixing table 27a. do.

Hereinafter, another embodiment of the propulsion means will be described with reference to the accompanying drawings.

The propulsion means 27 ′ shown in FIG. 9 may be exemplified as including a third elastic spring 27c for elastically pressing the aircraft 30 in one direction inside the rail 22a.

The third elastic spring (27c) elastically supports the aircraft 30 constrained on the rail (22a) by the second support protrusion (24b) in one direction, and then the operating cam (24) rotates and the second support protrusion ( When 24b) releases the restraint of the aircraft 30, the second-stage propulsion force according to the elastic restoring force of the third elastic spring 27c is directly applied to the aircraft 30, and the aircraft 30 obtains the second-stage propulsion and As the opponent moves at (20), it flies into the air.

On the other hand, the vehicle 30 separated from the propulsion cradle 22 may fly in the air by obtaining a three-stage propulsion force from the vehicle 30 itself. When the third-stage thrust is completely lost, the aircraft 30 glides on the airflow and lands on the ground.

The flying vehicle 30 flying by obtaining a three-stage propulsion is an example, a condenser motor (not shown) driven when a propeller 31 is mounted and separated from the rocket unit 20, and a flying body supporting the condenser motor ( 32), one side is mounted on the outside of the flight body 32 and the other side detects and detects the departure of the flight body 32 from the clip 33 and the propulsion cradle 22 connected to the rail 22a It may be illustrated as including a motion sensor (not shown) that generates a signal.

In addition to the above-described example, the vehicle 30 reveals that it can be variously modified into things such as a non-powered glider, a non-powered propulsion, a rubber-powered, condenser airplane, and the like.

First, the flight body 32 has a shape in which a plurality of lightweight plates are assembled into a general airplane shape, and there is no particular limitation on the shape. If necessary, a ground glider-type flying body capable of folding and spreading the wings may be adopted, and the necessary components may be further included.

The condenser motor may be made of known ones that rotate and drive the propeller 31 with a predetermined power charged by being placed in a proper place of the flying body, so a detailed description will be omitted. The accompanying drawings illustrate that the propeller 31 is disposed between a pair of tail wings formed at the rear end of the flying body 32, but the installation position is not particularly limited.

In particular, the condenser motor rotates the propeller 31 at the moment the aircraft 30 is separated from the propulsion cradle 22 to provide three-stage propulsion.

That is, when the motion sensor detects the departure of the vehicle 30 and generates a detection signal, the condenser motor rotates the propeller 31 according to the detection signal generated by the motion sensor.

Hereinafter, the operation of the flight rocket toy according to the present invention will be described with reference to the accompanying drawings. In this action, the operation process of the flight rocket toy will be described as an example.

First, in order to mount the aircraft 30 on the rocket unit 20, the clip 33 of the aircraft 30 is connected to the rail 22a, and at the same time, the elastic band 27b is attached to the fixing table 27a and the clip 33. To be mutually banded.

In this case, as shown in FIG. 4, the clip 33 is caught by the second support protrusion 24b and is constrained so as to be limited to launch on the propulsion cradle 22.

When the assembly (AS) in this state is mounted on the launch pad 10, the preparation for launch of the aircraft 30 is completed, and when the air pump 13 is strongly compressed with the foot, the compressed air rides the connecting hose 14 and the injection pipe 12 It is injected into the rocket body 21 and is strongly discharged.

The assembly AS is raised in the air by obtaining a first-stage propulsion force through compressed air, and when it reaches a certain height, it is pulled in a direction opposite to the upward direction by the wire 40. At this time, as shown in Fig. 6, the wire 40 pulls the release pin 23 in the other direction to be spaced apart from the first support protrusion 24a, and the operating cam 24 spaced apart from the release pin 23 is in one direction. The second support protrusion (24b) that was constraining the clip (33) on the rail (22a) while rotating to release the constraint of the clip (33) and at the same time, the elastic band (27b) is elastically restored to generate a secondary propulsion force. As the vehicle 30 slides on the rail 22a, it is separated on the propulsion cradle 22 and launched into the air.

On the other hand, the pulling of the release pin 23 is due to the provision of a traction force by the wire 40. In addition to the wire 40, the traction operation of the release pin 23 automatically turns the release pin 23 after a certain period of time has passed. It can also be equipped with a structure that can be towed by. In this case, the rocket unit 20 may further include components necessary for this, for example, an electronic timer.

As soon as the vehicle 30 is separated from the rocket unit 20, the condenser motor is operated so that the propeller 31 rotates to generate a three-stage propulsion force in the vehicle 30 itself.

Accordingly, the aircraft 30 flies in the air until all the charging power of the condenser motor is exhausted, and when the operation of the condenser motor is stopped due to the discharge of the power, it slides on the airflow and freely falls to the ground.

In summary, the flight rocket toy according to the present invention starts with the first thrust of the air pressure provided from the launch pad 10, the second thrust provided from the rocket unit 20, and the third thrust provided from the aircraft 30 itself. Since the aircraft 30 is given in stages, it is possible to secure a relatively long flight time as well as to be launched higher and farther.

The embodiments of the present invention described above are merely exemplary, and those of ordinary skill in the art to which the present invention pertains will appreciate that various modifications and other equivalent embodiments are possible. Therefore, it will be appreciated that the present invention is not limited to the form mentioned in the detailed description above. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims. In addition, the present invention is to be understood as including the spirit of the present invention as defined by the appended claims and all modifications, equivalents and substitutes within the scope thereof.
