Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a kite, and more particularly to a kite having a curved surface portion on the upper part of the kite body that can efficiently utilize wind pressure, and having a large wind-receiving surface at the lower part of the thread of the main body.

Generally, when the wind hits the main body of a kite, the wind pressure is distributed depending on the position of the threads on the kite string, with wind pressure acting on the wind receiving surface above the thread and wind pressure acting on the wind receiving surface below the thread. Due to the ratio of flies.

However, since the surface of the conventional kite body is flat, the wind pressure on the wind receiving surface particularly above the thread cannot be used efficiently. That is, when the kite body is tilted with respect to the airflow, the wind pressure per unit area on the kite body becomes relatively weak. For this reason, the wind-receiving surface above the strings has to occupy a large proportion of the entire kite body, and it has therefore been difficult to downsize the kite. Furthermore, if the surface of the kite body is flat, when the kite body loses its balance and turns upside down, the wind pressure distribution is reversed and the kite descends suddenly, making flight unstable.

It is an object of the present invention to solve the above-mentioned drawbacks and to propose a kite that can utilize the wind efficiently to obtain sufficient lifting force even under weak wind pressure conditions, and can also be made compact.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

In the drawings, reference numeral A designates a kite, and this kite A consists of a kite body 3 made up of a triangular wing-shaped body 2 attached to a long and thin windshield plate 1 so as to divide it into two halves with the apex facing upward. and a tail 4 attached to the lower end of the kite body 3. A curved surface 5 that curves backwards and backwards is formed on the upper part of the kite body 3, and a plurality of kite strings 7 are arranged near the upper part of the kite body 3. The threads 6, 6... are arranged vertically.

First, both the wind panel 1 and the wing-shaped body 2 are made of foamable synthetic resin. The upper part of the airfoil supporting surface of the wind panel 1 is curved to the rear and dorsal sides, and the upper part of the airfoil 2 attached to the support surface is also curved to the rear and back along the shape of the upper part of the wind panel 1, so that the curved surface part 5 is curved to the rear and back. It is formed. In addition to the above-described example, the kite body 3 may include a wing-shaped body 2 made of paper or a soft synthetic resin sheet stretched and supported by a supporting frame (for example, a hard synthetic resin pipe) (not shown). At the same time, it is also possible to form an appropriately shaped wind panel 1 made of paper or soft synthetic resin sheet and hanging below the support bone. Further, it is sufficient that the upper part of the kite body 3 is formed as a curved surface that curves toward the back and back, and may be a curved surface instead of a curved surface.

Next, near the upper part of the main body 3 of the wind panel 1, a plurality of threads 6, 6, . Kite string 7 on thread 6 above
When attaching the kite string, the end of the kite string 7 may be made into a ring shape, and the end portion 7 may be inserted through the slit 6a and hooked onto a suitable thread 6. Note that it is sufficient that at least two or more threads 6 are arranged vertically, and the shape thereof is not limited to the example illustrated above. For example, if the thread is made with round holes,
A configuration may also be adopted in which a hook-shaped locking metal fitting is attached to the end of the kite string and the locking metal fitting is locked to a thread at an appropriate position.

The proximal end of the kite string 7 is wound around a spool 10, and a magnet 11 is attached to the spool 10.

The tail 4 is made of a soft synthetic resin sheet, paper, etc., but is not necessarily necessary for the kite A. If double-sided tape or the like is attached to the base of the kite, it can be attached to and detached from the kite body 1 as desired depending on flight conditions.

As described above, the kite A is provided with a curved surface portion 5 that curves toward the back and back on the upper part of the kite body 3, so that the curved surface portion 5
can efficiently absorb wind pressure. That is, as shown in FIG. 2, when the kite body 3 forms a constant angle of attack with respect to the flow of the wind 8, the wind 8 hits the curved surface 5 at a substantially right angle. At this time, the wind pressure per unit area is close to the maximum, so even if the curved surface portion 5 is small, it can receive a large wind pressure, and the threads 6 that give lift to the kite body relatively.
Since the wind-receiving surface at the bottom of the kite A can be enlarged, the levitation of the kite A is greatly facilitated. Therefore, the entire kite A can be downsized. Moreover, since the wing-like body 2 is triangular in shape and attached to the elongated wind panel 1 so as to be divided into two halves with the apex facing upward, the kite A can be lifted even by turbulence.
can be kept in balance.

Moreover, since the threads 6 are formed in the upper part of the kite body 3 and in the vicinity thereof, together with the curved surface part 5, the wind pressure distribution is difficult to reverse, and therefore the flight is stable. Furthermore, since a plurality of thread stitches 6 are formed, when the kite string 7 is attached to the lower thread stitch 6, the kite A can obtain a large lifting force as described above, and the kite string 7 can be attached to the upper string stitch 6. 6, the curved surface portion 5 itself forms an angle of attack, and by the wind pressure acting on the curved surface portion 5, the kite A receives a lifting force and can float in the air.

Therefore, the kite A as a whole can be made smaller and can fly well even with air blown by a cooler 9, an electric fan, or the like. When the magnet 11 is attached to the spool 10 of the kite string 7 as in the illustrated example, the magnet 11 can be attracted to a metal surface such as the housing portion 9a of the cooler 9.

In addition, when the wind board 1 is an elongated plate-like body as in the illustrated example above, the wind board 1 has a rudder function, so that the kite A can have stable flight with little lateral oscillation. Further, since the upper part of the wing-shaped body 2 is curved, when the wing-shaped body 2 is made of foamable synthetic resin or the like, the strength against left and right bending is increased by the curved surface, and special reinforcing bones etc. are not required.

As explained in detail above, the present invention forms a curved part on the upper part of the kite body to promote levitation, and
The wing-like body has a triangular shape, and is pasted onto a long thin wind board so that it is bisected with its apex facing upward, and the optimal thread stitch can be selected, allowing for efficient use of wind pressure. This makes it easier to operate the kite body at the beginning of flying, and even young children can fly it easily. Also, because it can be made smaller,
You can easily fly a kite even in a light breeze, and you can easily enjoy kite flying indoors, in parks, in narrow places like alleys, etc.
Electric wires etc. do not get in the way. In this case, the product name or the like can be displayed on the surface of the kite, and the kite can be flown using air from an air conditioner in a store or the like, and can be used as an advertising medium. Moreover, since the threads are provided near the upper part of the kite body, a large lifting force can be obtained and flight stability is also good.
