Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a maneuverable assembly type which has a pleat provided at the trailing edge of a horizontal wing to stabilize a vertical posture and a means for changing the direction by operating a lifting thread. It is about kites.

[0002]

2. Description of the Related Art Conventionally, as a kite having maneuverability, a kite having an upper thread attached to a thread provided on the left and right through a dedicated device such as a clip has been used, and a triangular or rhombic flat kite or parafoil has been used. There were model kites.

[0003]

Many of the conventional kites with maneuverability have a large shape, and require a long thread and a certain strong wind to stably fly. . Therefore, there was a problem that it was not suitable for a narrow place. In addition, when the number of threads is plural, the threads are apt to be entangled, and there is a disadvantage that handling is troublesome.

[0004]

SUMMARY OF THE INVENTION The present invention seeks to form a camber that is easy to assemble, increases buoyancy in front of the horizontal wing, and reduces distortion of the entire kite at the trailing edge of the horizontal wing. Means for saving buoyancy that causes warping to occur is provided. By forming a curved surface on the entire kite in this way, the vertical posture can be stably lifted without having to take a long thread, so that the kite can be operated smoothly even with a lightweight and compact kite by simply attaching the lifting thread directly. become.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention provides a vertical wing in front of a horizontal wing having a bar on the back, a lifting thread attached to an appropriate position of the vertical wing, and Forming a camber that increases buoyancy, providing a means for saving the buoyancy applied to the rear of the kite, and providing means for turning with the operation of the lifting thread.

The means for saving the buoyancy applied to the rear part of the kite preferably has a structure which does not hinder the buoyancy of the kite.
For example, a wedge-shaped fold may be provided at the trailing edge of the horizontal wing.

When the kite constructed as described above is lifted, the portion provided with the wedge-shaped folds and the periphery thereof are bent upward, so that the buoyancy acting on the rear portion of the kite is saved. Therefore, the load on the bar can be reduced, and the buoyancy of the entire kite becomes higher than before, so that the center of gravity moves forward, so that the stability in the vertical direction is improved.

In order to form a camber as shown in the horizontal wing, it is preferable to provide a spindle-shaped fold at a boundary between the horizontal wing and the vertical wing.

The curved surface formed on the horizontal wing preferably has a shape close to that of a bird wing, which can provide a large buoyancy. For this reason, it is more effective that the position of the spindle-shaped fold is located slightly before the kite.

The means for turning with the operation of the lifting thread is provided with a thread hole serving as a thread at an appropriate position on the vertical wing, and is provided on the back of the kite as means for turning with the operation of the lifting thread. It is advisable to cross the yarns and attach them to both left and right ends of the rod.

When a crossing hole is provided in front of the kite when the crossing hole is provided in front of the kite, the crossed lifting yarn acts on the front edge, so that turning in the direction in which the line is drawn can be obtained, and the crossing hole is provided later. Since the crossed yarn acts on the trailing edge of the kite, it can turn in the opposite direction to the direction in which the yarn was pulled.

In the case where the cross hole is provided at the front side, when one of the left and right lifting yarns is pulled and one of the lifting yarns is loosened, the leading edge of the wing on the loose side is lifted, and the angle of attack is increased. As a result, the kite is tilted, and starts to turn in the direction of drawing the string. In this case, since the string is pulled against the tension of the rod, a reaction occurs with a certain threshold value until the kite starts turning.

If the force applied to the cross hole is large, the force applied to the thread hole will be lost, and the angle of attack cannot be maintained. Therefore, a return hole is provided at an arbitrary position slightly before the thread hole. It is preferable to deflect the force applied to the cross hole so that the function of the thread hole can be maintained.

[0014] When the crossing hole is provided later, since the crossed up thread acts on the trailing edge of the kite, when one of the left and right raised threads is pulled and one of the raised threads is loosened, the loosened side is removed. The trailing edge of the wing lifts, reducing the angle of attack. This causes the kite to tilt and begin turning in the opposite direction of drawing the string. In this case, since the action acts on the trailing edge of the bar with less tension, the turning can be performed with a slight difference in the right and left forces.

The folds of the present invention can be easily manufactured by applying pressure to a mold having irregularities in the form of folds with paper interposed therebetween. As a specific manufacturing method, a plurality of rectangular papers are arranged and pressed between molds formed such that a concave surface is formed on the front of the kite and a convex surface is formed on the back of the kite.

A wedge-shaped fold (9) is provided on the trailing edge (4) of the horizontal wing (1, 1), and the spindle is provided at the boundary between the horizontal wing (1, 1) and the vertical wing (2, 2) as shown in FIG. Creases (10, 10) are provided. A thread hole (6, 6) is provided at an appropriate position of the vertical wing, and a return hole (7, 7) is provided at a position slightly forward of the thread hole (6, 6). Horizontal wing (1,
Intersecting holes (8, 8) are provided slightly forward of the boundary between 1) and the vertical wings (2, 2). And the right raising thread (11)

Intersecting holes (8, 8) are provided at positions slightly behind the boundary between 1) and the vertical wings (2, 2). And the right thread (1
1) is passed from the thread hole (6) to the right turning hole (7), exits from the right crossing hole (8) to the back of the kite, and the tip is attached to the left end of the rod (12). Similarly, the left raising thread (8) is passed through the eyelet (6), and further through the left turning hole (7), and then out of the left intersection hole (8) to the back of the kite. Then, the tip is attached to the right end of the rod (12).

[0018]

The present invention has the following effects. Eliminating the glue makes it easy to disassemble and assemble, is inexpensive, suitable for mass production, and can be conveniently stored and transported.

The fold structure is flexibly deformed in response to a change in wind. For this reason, when a wedge-shaped fold is provided on the trailing edge of the horizontal wing, the portion provided with the fold and its surroundings warp upward to receive a strong wind. As a result, a sweepback angle is formed between the left and right horizontal wings, so that the overall distortion is reduced and the load on the bar can be reduced. Furthermore, since the center of gravity of the whole is shifted forward, the stability in the vertical direction improves,
The attitude of the kite can be stabilized.

Further, by providing a spindle-shaped fold at a position slightly forward of the boundary between the horizontal wing and the vertical wing having the above structure, a camber is naturally formed on the horizontal wing when the kite is lifted. It can be more stable.

From the above, even if a thin paper is used as the material, it can be fried without breaking its shape, so that the overall weight can be reduced. Also, compared to existing sport kites, there is less danger due to the lack of speed, and it can be fried even in places where the wind direction changes easily or in narrow places.

By applying a method of forming wedge-shaped folds or spindle-shaped folds by applying pressure to the paper sandwiched between the molds, it is possible to simultaneously form a large amount of the same shape.
