Abstract

PROBLEM TO BE SOLVED: To enable a model airplane to fly to a higher altitude with use of a rubber catapult by providing a forward looking hook and rearward looking hook part respectively on two model airplanes disposposed above and below to unite integrally both model airplanes with the bellies opposed to each other. SOLUTION: A forward looking hook part 3 and a friction part 5 are mounted respectively to the front part of belly side of one model airplane 1 and the rear part of the belly side, while a rearward looking hook part 4 and a friction part 6 are mounted respectively to the front part of the belly side and the rear part of the belly side of the other model airplane 2. The forward and rearward looking hook parts 3, 4 are hooked on both model airplanes 1, 2 with the bellies being opposed to each other so that both modell airplanes are united integrally with the friction parts being met with each other. In playing a rubber band of rubber catapult is hooked on a hook provided on the front part of the model airplane and after the rubber band is pulled to accumulate tension, the model airplanes are directed right above, shot and flied by separating the hands from the model airplanes.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a launching assisting device for assuring a higher altitude and stabilizing faster and more reliably by launching a combination of two model airplanes which glide at an initial speed and glide. is there.

[0002]

2. Description of the Related Art Conventionally, a model airplane that glides at a high altitude at an initial speed, such as a paper airplane fired by a rubber catapult, cannot be remotely controlled. When launched, the aircraft will flip over, failing to obtain sufficient altitude, and thus failing to obtain a sufficient flight distance and flight time. With reference to the drawings, the reason why a high-speed flight is caused will be described. Referring to FIG. 1, a model airplane that flies stably and generally has the following speed and glide angle stabilizing functions. B) The center of gravity is located before the center of lift, and the nose is lowered at low speed. This will increase speed. (B) The horizontal tail faces downward with respect to the main wing. Therefore, increasing the speed raises the nose. That slows down. It flies at a stable speed and glide angle with the balance between i and b. However, at high speeds, Ro works hard and raises the nose too much, causing somersaults. Also, when the nose is pointing up or down, Lee does not work and can't stop somersault. Conventionally, in order to increase the reach height by raising the height of this flip, the position of the center of gravity is lowered as shown in FIG. There was an adjustment method such as raising it.

[0003]

However, since it is different from the adjustment that flies stably and well, there is a drawback that the aircraft crashes unless the speed and the gliding angle are within a certain range in the sky. In addition, in order to raise the aircraft above, an exquisite combination of airframe adjustment, launch attitude, launch angle, and launch speed is required, and there is a drawback that adults must work seriously.
In addition, if the aircraft is adjusted to fly stably and well, as mentioned above, it will return to the sky when firing at high speed, and it will not be possible to take sufficient altitude, and therefore it will be possible to obtain sufficient flight distance and flight time. There was a disadvantage that it could not be done. When flying a stable and well-flying glider at high speed, it is expected that it will fly very well if it prevents nose-up and resumes nose-up when it reaches a sufficient altitude and slows down. However, there was no such model airplane.

SUMMARY OF THE INVENTION The present invention has been made to solve the problem. Referring to the drawings, in FIG. 3, a model airplane (1) is provided with a forward hook (3). At the front of the abdomen, a friction part (5) is attached to the back of the abdomen. Then, the hook portion (4) facing backward is attached to the front part on the ventral side of the model airplane (2), and the friction part (6) is attached to the rear part on the ventral side. Further, the forward hook (3) and the backward hook (4) are hooked, and the model airplane (1) and the model airplane (2) are connected to each other, and the friction unit (5) and the friction unit (6) are connected. Match. A model airplane launch assistance device having the above configuration. In addition, in FIG. 4, the front hook portion (3) is attached to the rear side of the model airplane (1), and the friction portion (5) is attached to the rear front portion. And the model airplane (2) also has a rearward hook (4)
Is attached to the rear part on the back side, and the friction part (6) is attached to the front part on the back side. Further, the forward hook (3) and the backward hook (4) are hooked, and the model aircraft (1) and the model aircraft (2) are back-to-back, and the friction unit (5) and the friction unit (6) are connected. Match. A model airplane launch assistance device having the above configuration.

DESCRIPTION OF THE PREFERRED EMBODIMENTS When using the present invention, as shown in FIG. 5, model airplanes (1) and (2) which fly stably and well, with (1) to (6) attached, etc. Fire together at high speed. Or fire at high speed, back to back. Hook (7) when firing with rubber catapult
With a tail (8) that can be picked at once, or with such a head or tail. A rubber band (10) is attached to the tip of the rod (9), and the rubber band (10) is hung on the hook (7) and the tail (8) that can be picked at a time is picked at a time. While pulling the stick (9) and the tail (8) that can be picked at a time, pull it upwards and release the tail to fire.

[0006]

Embodiments will be described with reference to the drawings.
3 and 5, two model airplanes (1) and (2) having a forward hook portion (3) and a rearward hook portion (4) are made to face each other, and a friction portion (5) is combined. Fire with a rubber catapult. When launching with a rubber catapult, hook the rubber band (10) on the hook (7), hold the tail (8) that can be picked at once with your right hand, and hold the stick (9) with the rubber band (10) with your left hand, and pull. Extend the rubber. When you lift your finger from the tail (8), which is picked up at once, the two aircraft are fired together and rise almost straight.
During a rapid climb at high speed, the two aircraft fly face-to-face or face-to-face, canceling the nose-lifting force and maintaining the face-to-face or face-to-face state with the nose-lifting force. When the altitude reaches a sufficient altitude and the speed drops, the nose-lifting force fixed to the belly becomes smaller, the two aircraft separate with a slight force, and the nose-lifting power does not cancel each other, and each becomes a stable posture. Start gliding back. The method of giving the initial speed does not have to be a rubber catapult, and the relationship between the right hand and the left hand may be either. In addition, in the case of firing back-to-back, as shown in FIG. 4, only the mounting positions of the front hook portion (3), the rear hook portion (4) and the friction portions (5) (6) are reversed, and other The implementation method is the same. The shape of the forward hook portion (3) and the rear hook portion (4) is as shown in FIG. 6, but the mounting portions and mounting methods for the model airplanes (1) and (2) indicated by dotted lines are arbitrary. The friction portions (5) and (6) may be the fuselage or wings of the model airplanes (1) and (2), and need not be in contact with each other as long as they have the same aerodynamic effect.

[0007]

By using the present invention, a high altitude can be attained fairly surely even with an inexpensive non-powered and non-steered model airplane, and even when the flight is adjusted stably and well. This allows you to enjoy long and long-haul flights without crashing. Moreover, the possibility of getting on the updraft increases accordingly. If you have an updraft, you can keep flying until it disappears. In addition, since two aircraft are fired simultaneously under the same conditions, it is possible to compete for flight time and flight distance. Moreover, the most significant feature is that the child, who is the main purchaser and user of the model airplane, can easily carry out these matters. It can resemble a real machine, compete in skills, or resemble an aerial battle as children like.
