Description

[Detailed description of the invention] (Field of industrial application) The present invention is attached to an appropriate traveling toy that can move at an appropriate speed by a built-in drive device, and is towed by the movement of this traveling toy. The present invention also relates to a parachute for a traveling toy that uses the air resistance and air flow experienced during towing to stably move while remaining in a position above the traveling toy (floating in the air).

(Prior Art) Conventionally, a parachute for a traveling toy of this type that is towed by a traveling toy has been disclosed in Japanese Patent Application Laid-Open No.
A toy vehicle with a parachute as described in Publication No. 96138 has been created. This involves fixing multiple strings to the periphery of the parachute body, gathering the base ends of the strings together, and
This assembled part was attached to the hook of a traveling toy.

(Problem to be solved by the invention) However, when a parachute like the one described above is towed by a traveling toy, the parachute itself tends to rotate, and the strings may get twisted.
It was difficult for the parachute itself to move stably while remaining above the traveling toy (floating in the air), and there was a risk that it would come into contact with the traveling surface or be dragged.

(Means for Solving the Problems) Therefore, the present invention solves the above-mentioned difficulties and provides a parachute for a traveling toy that can stably maintain a floating state by being towed by the traveling toy. Specifically, it is attached to an appropriate traveling toy A that can move at an appropriate speed by a built-in drive device, and is towed by the movement of this traveling toy A. At the same time, by utilizing the air resistance and air flow experienced during towing,
In a parachute for a traveling toy configured to move while remaining in a position above the traveling toy A, a parachute main body P1, a string P2 whose tip portion is fixed to the parachute main body P1, and a base end of the string P2 are arranged. Attachment P that is fixed and can be attached to traveling toy A
It consists of 3. And the parachute body P1
The folding portions 1 are disposed on a suitably foldable approximately circular cloth so as to be symmetrical with respect to a vertical line passing through the center of the cloth and at approximately equal intervals along the circumferential direction. It is formed to have a hemispherical shape. Then, the string P2 is composed of a plurality of hanging strings 2 and two tow strings 3, and the tip of the hanging string 2 is connected to the folded part 1.
The base end of the hanging cord 2 is fixed to the folding part 1 provided in the left half of the parachute body P1, and the hanging cord 2 is fixed to the folding part 1 provided in the right half of the parachute body P1. The proximal ends of the tow strings 3 are tied separately, the tips of the tow strings 3 are fixed to the tied portions of the suspension string 2, and the proximal ends of the tow strings 3 are fixed to the string attachment part 10 of the fixture P3. Furthermore, the fixing positions of the ends of each of the hanging cords 2 fixed to the folding parts 1 at the bottom left and right sides of the parachute main body P1 are changed from those of the other hanging cords 2.
A means for setting each tip end fixing position closer to the center of the parachute main body P1 was adopted.

(Function) By adopting the above-mentioned technical means, the fixed positions of the ends of each of the hanging cords 2 fixed to the folding parts 1 at the lower left and right sides of the parachute main body P1 are different from those of the other hanging cords 2. When the parachute P is towed by the traveling toy A and the parachute P receives air resistance, the air flow starts from the lowest part of the parachute main body P1. A large amount of water flows downward as if escaping, and the parachute main body P1 remains raised to a predetermined position (floating in the air) along with the traveling toy A due to the relationship between the towing speed of the traveling toy A and the air flow. Begins to move.

In addition, the two tow cords 3 are connected to the parachute body P.
1 and a traveling toy A, and prevents the parachute main body P1 from rotating due to the rotational force in the left and right direction applied to the parachute main body P1.

(Example) The present invention will be described below with reference to illustrated examples.

The parachute P of the present invention is an appropriately traveling toy A that can be moved at an appropriate speed by a built-in drive device.
The toy is attached to the toy A and is towed by the movement of the toy A, and is configured to move while remaining in a position above the toy A by utilizing the air resistance and air flow experienced during this towing. , a parachute main body P1, a string P2 whose tip portion is fixed to the parachute main body P1, and a fixture P3 fixed to the base end of the string P2 and freely attachable to the traveling toy A.
It consists of.

The parachute main body P1 has foldable parts 1 arranged on a freely foldable, approximately circular cloth made of an appropriate material, symmetrically with respect to a vertical line passing through the center thereof, and at equal intervals along the circumferential direction. The whole is formed to have a substantially hemispherical shape. in particular,
For example, using approximately circular cloth with a diameter of approximately 330 mm,
The outer edge of the folded part is about 5 mm deep, and the folded part gradually becomes shallower as you go to the center of the folded part 1, and the folded part disappears about 70 mm from the outer edge towards the center. There are approximately triangular shaped folding parts 1, and these folding parts 1 are arranged at four places on the left half and at four places on the right half at intervals of about 45 degrees.

The string P2 includes a plurality of (for example, eight) hanging strings 2.
and two tow strings 3, each of which has its tip portion fixed (for example, connected) to the folded part 1, and is fixed to the folded part 1 provided on the left half of the parachute main body P1. The base ends of the hanging cords 2 that are attached to the parachute body P1 and the base ends of the hanging cords 2 that are respectively fixed to the folding portion 1 provided in the right half of the parachute main body P1 are tied separately, and the two tow cords 3 are The tip is the hanging cord 2
The base end thereof is fixed (for example, connected) to the string attachment part 10 of the fixture P3.

By the way, the tips of the hanging cords 2 fixed to the folding part 1 at the bottom of the left half of the parachute main body P1 and the hanging cords 2 fixed to the folding part 1 at the bottom of the right half of the parachute main body P1. The fixing position is set at an appropriate distance (for example, about 22 mm) closer to the center than the outer peripheral edge of the parachute main body P1.
In addition, the tip of the other hanging cord 2 is attached to the parachute body P1.
It is fixed to the outer periphery.

The attachment P3 includes a cord attachment part 10 that is formed so that the base end of the tow cord 3 can be fixed, and is connected to the cord attachment part 10, and is attached to the parachute release device B at an appropriate interval (for example, about 65 mm). Insertion hole 15 provided in
an insertion section 11 that is forcibly inserted into and removably;
It consists of a flange part 12 provided circumferentially between a string attachment part 10 and an insertion part 11.

The string attaching part 10 has a small hole drilled therein so that the tow string 3 can be connected thereto, and the insertion part 11 has a substantially heart-shaped ring shape with a sharp tip to facilitate insertion into the insertion hole 15. In addition, the insertion portion 11 itself is formed to be easily elastically deformed when inserted into the insertion hole 15.

In addition, when the insertion part 11 is forcibly inserted into the insertion hole 15, the maximum height of the insertion part 11 is larger than the opening length of the insertion hole 15, so the insertion part 11 can absorb the air that the parachute P receives. If there is only so much resistance, it will not be easily removed from the insertion hole 15. Further, the flange portion 12 is in close contact with the edge portion of the insertion hole 15, and the jaw-shaped portion of the insertion portion 11 and the flange portion 12 press the edge portion of the insertion hole 15 from the front and back, so that the fixture P3 is fixed. (See Figure 4).

By the way, the attachment P3 may be detachably attached to the insertion hole 15 of the parachute release device B as shown in the example, or it may be fixed at a predetermined position of the parachute release device B, although not shown. It may be shaped like this, and the fitting P
The configuration, shape, etc. of 3 are not limited to the illustrated example.

The traveling toy A is formed to be able to change direction and adjust speed by radio control, and can have an appropriate form and configuration.

The parachute release device B is configured to store the parachute P in a folded state, and is activated to release the parachute P into the air when, for example, a receiver receives a signal from a transmitter. . The insertion holes 15 into which the fixtures P3 of the parachute P are inserted are respectively formed in extruded bodies that push out the parachute P using the elastic force of the elastic spring.

(Effect of the invention) Therefore, according to the parachute for a traveling toy of the present invention, by being towed by the traveling toy A, it can stably maintain a floating state in the air, and this kind of traveling toy As a parachute for
It will be the best one. Moreover, its configuration is simple,
It is suitable for mass production and can be provided at low cost.

Then, the folded portions 1 are arranged on a suitable approximately circular cloth so as to be symmetrical with respect to a vertical line passing through the center of the cloth and at approximately equal intervals along the circumferential direction,
Since the parachute P is formed to have a substantially hemispherical shape as a whole, the parachute P is well balanced when subjected to air resistance, and the parachute P in the towed state is difficult to swing from side to side or rotate.

Moreover, the base end of the hanging cord 2 fixed to the folding part 1 provided on the left half of the parachute body P1, and the base end of the hanging cord 2 fixed to the folding part 1 provided on the right half of the parachute body P1. The tips of the tow strings 3 are fixed to the tied portions of the suspension strings 2, and the proximal ends of the tow strings 3 are fixed to the string attachment part 10 of the fixture P3, so that the parachute main body P1
The left and right halves of the parachute are able to receive air resistance in a well-balanced manner, and the parachute main body P1 does not try to rotate or shake due to the horizontal rotational force generated in the parachute main body P1 in the towed state. can be reliably prevented, and the string P2
It also won't get twisted.

In particular, the fixing position of the tip of each of the hanging cords 2 fixed to the folding part 1 at the lower left and right bottom of the parachute body P1 is set closer to the center of the parachute body P1 than the fixing position of the tip of each of the other hanging cords 2. Therefore, when the parachute P is towed by the traveling toy A and the parachute P is subjected to air resistance, a large amount of air flows downward from the lowest part of the parachute body P1, and this It becomes the force that increases P1,
The parachute P itself can now move stably while staying above the traveling toy A (floating in the air), and there is a risk that the parachute body P1 may come into contact with the traveling surface or be dragged. It becomes a thing without a trace.

Furthermore, since the ends of the hanging cords 2 are each fixed to the folding portion 1, the fixed portions between the parachute body P1 and the cords P2 can be strengthened, and the parachute body P1, which is subject to air resistance, will not break from the fixed portions of the hanging cords 2. It becomes difficult.
