Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a flying toy, and more specifically, a rotor that is rotated using the unraveling force of a wound rubber string as a driving source, and a rotor that is removably connected to the rotor. The present invention relates to a flying toy that is equipped with a gliding body that can separate in the sky and that allows the rotor and the gliding body to fly separately.

(Prior Art) Flying toys have been known that include a rotor that rotates using the unraveling force of a wound rubber string as a driving source.

However, in conventional flying toys of this type, the rotor and the body of the flying object are integrated, and can only be used as a so-called gyroscope toy that flies mainly in the vertical direction. It was a strange flying toy that only fell down.

(Purpose of the invention) The present invention was made to eliminate the above-mentioned drawbacks of the conventional technology. When the lift limit is reached, the rotor and the main body automatically separate, and the main body functions as a gliding body for the space shuttle. The object of the present invention is to provide a flying toy configured so that the toy can land while gliding and descend while the rotor is rotating like a disk.

(Summary of the invention) In order to achieve the above purpose, in this invention, one end of the rubber string is hooked on the nose side, an arm is provided on the rotating shaft that winds the rubber string, and an arm is placed in the center of the rotor. An engaging part that engages with the arm of the rotating shaft is provided in the cylinder, and the structure of the engaging part is such that when the flying toy reaches its lifting limit and the unraveling force of the rubber string weakens, the engaging part engages with the arm of the rotating shaft. The structure is such that the engagement between the two ends can be released.

(Example) Hereinafter, details of the present invention will be explained based on an example shown in the drawings.

Figure 1 and subsequent figures show an embodiment of the present invention.
The flying toy 7 is composed of a gliding body 2 and a rotor 3. By rotating this rotor 3 with a fingertip, a rubber string 4 is wound in, and the unraveling force of the rubber string 4 causes the rotor 3 to rotate and rise as a whole, and at the upper limit, the rotor 3 and the gliding body 2 are automatically separated. Can be separated.

Below, each part will be explained in detail. First, the gliding body 2
has a core material 5 made of wood or the like, and a main wing 6 made of a foamed synthetic resin plate or the like is fixed to the core material with adhesive or the like, and a tail 7 is also attached to the rear of the center of the main wing 6. It is glued together and has an overall shape similar to a space shuttle.

A support member 8 is fixed to the tip of the core material 5, and a support member 9 is fixed to the rear end. The support member 8 is provided with a rotating shaft 10 made of steel wire or the like.
The arm 11 is fixed at the tip of 0 in a perpendicular state.

A rubber string 4 is stretched between the hook 10a at the lower end of the rotating shaft 10 and the support member 9 at the rear end of the core member 5 in a state where it is folded back several times.

On the other hand, the rotor 3 has a cylinder 12 at its center, and a total of four blades 13 are provided protruding from the outer peripheral surface of the cylinder 12 at equal angular intervals in the circumferential direction. A circular frame 14 is integrally provided at the tip of the blade 13.

Spiral protrusions 15, 15 are formed on the inner circumferential surface of the cylinder 12 in a left-right symmetrical manner, covering approximately half the circumference.

The lower end of each spiral protrusion 15 is continuous with the protrusion 6 forming a horizontal surface on the lower surface side of the circumference 12 (see Fig. 4), and the upper surface of each protrusion 16 extends to the upper end of each helical protrusion 16. A vertical protruding piece 17 is continuously formed. A ratchet wheel 18 is also formed on the outer peripheral surface of the lower half of the cylinder 12. As shown in FIG. 4, a plurality of ratchets of the ratchet wheel 18 are formed at a predetermined pitch so that the ends in the clockwise direction form an upright wall when viewed from the bottom of the rotor 3.

On the other hand, the one indicated by numeral 19 has a rubber string 4 at hand.
It is a launch pad provided to store power and facilitate flight operations, and is formed from synthetic resin as an approximately "L"-shaped frame with angular edges, the upper end of which is a horizontal part 19a. The lower end is bent upward at a right angle to form a bent portion 19b.
A slide frame 20 is slidably fitted into this horizontal portion 19a, and the slide frame 20 has arms 21, 21 divided into two forks at its tip, and each arm 21
A groove 21a is formed inside the groove 21a.

A substantially C-shaped support frame 22 that is open toward the arm 21 is formed on the upper surface of the slide frame 20. A protrusion 23 that engages with the ratchet of the ratchet wheel 18 is formed inside the tip of one side of the slide frame 20. In addition, C
The inner diameter of the letter-shaped support frame 22 is approximately equal to the outer diameter of the cylinder 12 of the rotor 3.

On the other hand, a uniform lever 2 is provided at the lower end of the launch pad 19.
The lower end of 4 is rotatably supported via a pin 25. There are a pair of left and right levers 24, and their upper ends are rotatably supported on both sides of the base of the slide frame 20 via pins 26. Therefore, lever 2
4 via the pin 25, the slide frame 20 can slide back and forth along the horizontal portion 19a at the upper end of the launch pad 19.

Next, the usage and operation of the flying toy of the present invention constructed as above will be explained.

First, a case where the launch pad 19 is not used will be described. In this case, the cylinder 12 of the rotor 3 is pinched and the arm 11 provided at the upper end of the rotating shaft 10 is fitted into the cylinder 12 from the end of the cylinder 12 on the side where the ratchet wheel 18 is formed. .

At the end of the cylinder 12 on the side where the ratchet wheel 18 is formed, there is a protrusion 1 as shown in FIG.
Spiral protrusion 15 except for the part where 6 and 16 are formed
Since the length of the arm 11 is almost equal to the inner diameter of the cylinder 12, the upper surface of the arm 11 is inserted into the cylinder 12 along the lower surface of the spiral protrusion 15 and the inner peripheral surface of the cylinder 12. Once fitted, the vertical protrusion 1
7, the lower surfaces of both ends of the arm 11 can be brought into contact with the upper surface of the end of the horizontal projecting piece 16.

This state is the state in which the rotor 3 is coupled to the glide body 2. At this time, even if the rotor 3 is rotated counterclockwise in FIG. 4, the arm 11 is locked by the projections 16 and 17, and the rotor 3 will not separate from the arm 11, that is, the glide body 2. Therefore, by placing a fingertip on the side surface of the blade 13 from the upper surface of the rotor 3 and rotating the rotor 3 clockwise, the rubber string 4 can be wound up.

After wrapping the rubber string 4 sufficiently in this way, hold the rotor 3 and the gliding body 2 with both hands, and with the core material 5 facing vertically upward, throw the whole thing out toward the ground. When released, the rotor 3 is rotated by the releasing force of the rubber string 4, and the rotor 3 rises together with the gliding body.

When ascending, the arm 11 is rotated counterclockwise when viewed from above, so both ends of the arm 11 are aligned with the cylinder 12.
The rotor 3 is rotated counterclockwise in order to push the side surface of the protrusion 17 formed vertically therein counterclockwise, and the lower surfaces of both ends of the arm 11 are on the protrusion 19.
The rotor 3 and the glide body 2 do not separate, and the glide body 2 continues to rise while rotating along with the rotor 3.

After climbing about 20 meters, the unraveling force of the rubber string 4 weakens, and when the entire body reaches its lifting limit, the force of the arm 11 pushing against the side surface of the vertical protrusion 17 weakens, and the gliding body 2
There is a relative rotational shift between the two, and the arm 11 separates from the vertical protrusion 17 and the horizontal protrusion 16, and the arm 11 becomes free. As a result, the glide body 2 separates from the rotor 3 due to its own weight and separates as shown in Figure 2, and the rotor 3 becomes lighter and flies while rotating, while the glide body 2 initially falls, but due to the wind Since the overall balance is maintained by force, it quickly regains its horizontal position and uses its main wings and tail to glide and land like a space shuttle. On the other hand, even after separation, the rotor 3 continues to rotate due to inertia and lands following its own wake.

On the other hand, how to use and operate the flying toy when using the launch pad 19 will be explained. That is, when using the launch pad 19, the launch pad 1
Hold lever 9 in your hand and press lever 2 as shown in Figure 5.
4 in the clockwise direction in FIG. 5 about the pin 25. As a result, the slide frame 20
Push forward from 9a. In this state, slide frame 2
The support member at the upper end on the sliding body 2 side is fitted into the groove 21a formed inside the arms 21, 21 of 0.
At this time, they are fitted so that the rotating shaft 10 is on the inside.

As is clear from FIG. 7, protrusions 8a are provided on both sides of the support member 8 to fit into the grooves 21a. Also, although not shown, the support member 8
A projection is formed on a part of the side surface of the arm 21 to be fitted into a recess formed on one side of the arms 21, 21, and the support member 8 is fitted between the arms 21, 21. can be held securely. In this state, the arm 11 is above the slide arm 20 and positioned inside the C-shaped support frame 22, as shown in FIG.

After the glide body 2 is attached as described above, the cylinder 12 of the rotor 3 is fitted into the support frame 22 with the ratchet wheel 18 facing downward. Then, the cylinder 12 and the arm 11 are engaged as in the case where the launch pad is not used. Next, place your fingertips on the blades 13 of the rotor 3 and rotate them in a direction to wrap around the rubber string 4. Even if the fingertip is released with the rubber string 4 fully wrapped, the rotor 3 will not rotate because the protrusion 23 engages with the ratchet of the ratchet wheel 18.

The launch preparation is now complete, so hold the launch pad 19, put your finger on the lever 24, and pull the lever 24 toward you, the slide frame 20 will retreat, and the horizontal section 19
Since the tip of a pushes the support frame 8 held between the arms 21, 21, the rotor 3 moves away from the launch pad 19 together with the gliding body 2, and rises in the same manner as described above due to the unraveling force of the rubber string 4.

(Effects of the invention) As is clear from the above explanation, according to the invention, the rotor and the gliding body are separated by the relative rotational deviation due to the weakening of the unraveling force of the rubber string at the upper limit of the flying toy. The rotor and gliding body separate near the limit of its ascent, and the rotor continues to fly like a disk while the gliding body glides like a space shuttle. It is possible to obtain a flying toy that can touch the ground and land on the ground, resulting in a flying toy with unprecedented changes in motion.
