Description

  The present invention relates to a flying disk that can be fly as a flying object.

Conventionally, a flying object described in Patent Document 1 is known as a disk-like floating body. The flying body includes an upper blower composed of rotary blades that pump air in the axial direction and a lower blower composed of rotary blades that pump air fed from the upper blower in the opposite directions. It consists of a structure arranged coaxially so as to rotate. In the turbo fan on the upper blower side, air sucked in from the centrifugal direction is pumped in the axial direction through the through hole, and in the turbo fan on the lower blower side, the air sucked in through the through hole is centrifugally fed It is something that is pumped to
Also, a flying disk that is held in the hand and is thrown away, such as a disk described in Patent Document 2, is known. The flying disk has no power, and the flight time and reach distance are determined according to the given initial speed while maintaining the posture by the rotation given at the time of release.
Further, there is known a flying play equipment described in Patent Document 3 in which a circular outer periphery is constituted by an annular elastic wire, and a blade for generating buoyancy by rotation of the annular elastic wire is provided inside.
Further, a flying instrument described in Patent Document 4 that moves horizontally using a double rotor, in which main power and a main body are reversed to obtain buoyancy, is known.

The flying body described in Patent Document 1 generates buoyancy that rises upward due to the air flow generated by the fan. The upper air blower provided in the upper part of the airframe and the lower air blower provided in the airframe are provided. By rotating in the opposite direction relatively, the aircraft is not rotated. Therefore, the flying object cannot be used as a flying object such as a flying disk that is thrown in the horizontal direction and reaches far.
The disk described in Patent Document 2 is a type of general flying disk that does not have power, and can fly while drawing various trajectories according to the direction, initial speed, rotation speed, and posture at the time of throwing. It can be done. And when flying horizontally, it is thrown at a certain initial speed according to the distance to reach, so even when the flying disc is caught, it must be received at a relatively high speed. The same applies to the flying play equipment described in Patent Document 3.
Further, the propeller flying tool described in Patent Document 4 is configured to generate upward and horizontal propulsive forces by two propellers. Unlike a flying disk, it is not thrown against humans, and there is no example of mounting such a propeller flying device on a flying disk that assumes a throwing operation.

An object of the present invention is to provide a flying object that can reach a distant place in a stable posture as a flying disk. In other words, it is a flying disc that can be thrown and used by a player as a flying object, and can provide a certain flight distance even if it is not an expert, and slowly when the speed of horizontal movement decreases. It is an object to provide a flying disk that descends and is easy for an opponent to catch. Furthermore, in order to realize the said subject, it is a subject to provide the structure which can aim at the increase in buoyancy, the stability of a posture, and the maintenance of a driving force by rotation of the airframe using the reaction force accompanying rotation of a propeller. It is what.
Propellers that generate buoyancy when the player's hand is released during throwing rotate and maintain that state in the air, providing a flying disc with a mechanism that stops propeller rotation when the flight ends It is an object to do. It is another object of the present invention to provide various means for causing the propeller to start or stop rotating automatically or by any operation of the user.
In addition, this invention is invention which aims at solving the subject which combined all or the selected single or any one of the said subject.

When the wing-like member is provided, the rotation of the disk main body can be made continuous in addition to the reaction force of the propeller.

Further, the flying disk is thrown by a player's hand, and has a switch or a sensor for rotating a propeller connected to the driving device. Further, the switch or sensor is configured to detect the start of flight and automatically rotate the propeller.
Since it is desirable that the flying disk is lightweight, a large-capacity battery cannot be mounted. For this reason, a switch or a sensor for controlling the driving of the propeller is required in order to suppress the consumption of the electric power generated when the aircraft is not in flight. Further, when the propeller driving start and stop are automatically controlled using a sensor capable of detecting the start and end of flight, it is possible to further prevent wasteful power consumption.

Also, a flying disc thrown by the player's hand,
It has a centrifugal force switch configured to rotate the propeller connected to the driving device by energizing with the rotation of the disk body, and the propeller is rotated by the rotation of the disk body accompanying the flight, and the flight ends. The rotation of the propeller is stopped by lowering or stopping the rotation speed of the disk body.
The present invention is provided with a switch for detecting a centrifugal force and closing a circuit as one means of a sensor capable of detecting the start and end of flight. By controlling the start and stop of driving of the propeller using the centrifugal force switch, it is possible to prevent wasteful power consumption.
Since the flying disk has buoyancy due to the rotation of the propeller, the flight time is longer than the conventional flying disk released at the same initial speed, and it flies slowly so as to descend when it reaches the receiving side. is there. Further, since the propeller rotation start and stop can be linked with the flight, there is no troublesome operation of the switch, and the power consumption can be reduced and the battery consumption can be suppressed.

The flying disk according to the present invention has a propeller, and flies in a substantially horizontal direction while generating buoyancy by the rotation of the propeller. If the initial speed at the time of throwing is the same, the flight distance becomes longer in proportion to the flight time. Since the flying disk according to the present invention has a propeller, the flight time becomes longer, and the flying disk can fly farther than a flying disk without a propeller.
In addition, since the propeller switching is synchronized with the rotation of the disc body accompanying the flight, the propeller rotation can be maintained by maintaining the energized state of the switch by centrifugal force during the flight. A complicated operation such as turning on and off is unnecessary.
Further, the flying disk according to the present invention flies at a certain height until the end of the flight, and flies so as to descend slowly as the horizontal movement speed decreases. Therefore, it has the effect that it is easy to catch the flying disc that has been flying.
In addition, the rotation of the disk body is indispensable for maintaining the flying posture in the air, but the disk body is kept rotating by the wing-like member that receives the reaction force and air flow accompanying the rotation of the propeller. Yes. For this reason, the flying disk according to the present invention has an effect that the flight can be finished while maintaining the posture until the end because the disk main body continues to rotate until it almost stalls and descends.

It is a plane (upper surface) figure of a flying disk. FIG. 3 is a side view of the flying disk (partly taken along the X-X ′ section in FIG. 1). It is a bottom view of a flying disk.

Hereinafter, embodiments for carrying out the invention will be described with reference to the drawings.
In each figure, reference numeral 1 denotes a flying disk according to the present invention. The flying disk 1 is composed of a disk main body 2 shaped like a dish with an outer shape of about 20 to 30 cm and a propeller 3 rotating at a position protruding from the upper surface of the disk main body 2.
The disc body 2 is formed as a thin-walled structure having a rigidity of a diameter of 23 cm and a height of about 3 cm as an optimal form. The disc body 2 in the present embodiment is formed by a thin frame 4 formed in a lattice shape with a synthetic resin and a resin film 5 covering the frame 4. The disc body 2 is not limited to this structure, and other structures may be adopted.

The disc main body 2 has an external shape like a dish with a circular opening 6 formed in the center, and the height of the disc main body 2 is roughly set on the outer periphery of the substantially flat upper wall portion. The side wall 7 has a shape that is curved downward with a curvature such that the radius is set to a radius of. Note that the shape of the side wall 7 is not limited to a curved surface, and an appropriate shape is adopted in consideration of flight efficiency and the like, for example, as an inclined surface including a linear element.
When the disc body 2 having the above structure is released in the horizontal direction while being rotated, the shape of the outer peripheral portion and the upper wall portion excluding the opening 6 hold the buoyancy and fly by inertia.

As an example, the disk main body 2 is formed by a frame 4 for maintaining the shape and a resin film 5 covering the frame 4. The frame 4 is formed in a thin and narrow lattice shape capable of maintaining a disk shape, and covers the whole with a resin film 5 so as to close an opening such as a window formed between the lattices. Yes. For example, a heat shrink film is used as the resin film 5, and the resin film 5 is heated and shrunk after covering the entire frame 4 so as to be in close contact with the frame 4. In addition, even if the part comprised with the flame | frame 4 and the resin film 5 is formed as one integral member, it does not interfere.
The reason why the disk main body 2 is formed as described above is that the disk main body 2 is formed to be lightweight while maintaining the shape of the disk. The frame 4 is formed in a lattice shape having openings. However, the frame 4 may be formed as a closed thin film in a region corresponding to the openings so as to have the same function as a stretched film. Is.

A mounting plate 8 for the propeller 3 is provided at the center of the opening 6. The mounting plate 8 is a portion that is integrated with the frame 4 and is a circular portion that is supported by a spoke-like arm 11 that extends from the center of the upper wall surface toward the outer peripheral side.
A drive unit 9 for rotating the propeller 3 is provided on the back surface of the mounting plate 8. The drive unit 9 includes a battery, a motor, a gear group coupled to the motor shaft, and a case housing these. When the centrifugal force switch 12 described later is closed, the drive unit 9 rotates the motor, and rotates the drive shaft 10 protruding above the mounting plate 8 via the gear group. The propeller 3 is attached to the drive shaft 10, and the propeller 3 is rotated by the rotation of the drive shaft 10.
As described above, the propeller 3 is disposed at the center of the opening 6 formed at the center of the disc body 2, but the center of the opening 6 where the propeller 3 is disposed is limited to the center point of the opening 6. It does not mean a narrow range. That is, it refers to a region having a certain range on the central axis of the disk main body 2, and the arrangement of the propeller that exerts the action of allowing the air flow to pass from the upper side to the lower side through the opening 6 is referred to as the central part of the opening 6. It is.
Therefore, the central portion of the opening 6 where the propeller is disposed is not only above the mounting plate 8 from which the drive shaft 10 is protruded, but also exhibits the characteristics of the flying disk according to the present invention. As long as it is formed, the case where the propeller is disposed at the same height as the upper wall surface of the disk body 2 substantially the same as the mounting plate 8 or the case where the propeller is disposed at a position lower than the upper wall surface of the disk body 2 is included. It is a waste. The propeller 3 is preferably provided at a position slightly higher than the upper wall surface of the disc body 2 as shown in the figure, and the flight posture is set by suspending the disc body 2 by the propeller 3 that generates buoyancy. It is easy to stabilize.

In the present embodiment, four spoke-like arms 11 (11a, 11b, 11c, 11d) supporting the mounting plate 8 are provided. A centrifugal force switch 12 is attached to the back surface of one of the four arms 11a.
The centrifugal force switch 12 is a switch configured to close the circuit when centrifugal force or the like is generated in a certain direction. The centrifugal force switch 12 used in the present embodiment is configured such that an iron ball accommodated in the inside presses an internal contact by centrifugal force to energize, and the energization is canceled together with the disappearance of the centrifugal force. It is comprised so that it may do.

The centrifugal force switch 12 is provided along the arm 11 a provided from the center to the outer periphery, and is energized by the centrifugal force accompanying the rotation of the disk body 2. The centrifugal force switch 12 closes a circuit connecting the motor and the battery built in the drive unit 9 and rotates the propeller 3 by rotating the motor. That is, the propeller is rotated with the rotation of the disk body 2. The propeller 3 rotates in the counterclockwise direction when viewed from above.
A weight 15 for balancing the weight with the centrifugal force switch 12 is attached to the arm 11c at a diagonal position of the arm 11a.

Further, each arm 11a, 11b, 11c, 11d facing the opening 6 that communicates vertically is provided with a blade (wing member) 13 (13a, 13b, 13c, 13d) having an inclined surface. Each wing 13 receives a descending air flow generated by the propeller 3 and generates a force for rotating the disk body 2 in the anti-propeller direction. The wing 13 is formed as an inclined plate inclined toward the moving (rotating) direction.
The wing-like member is subjected to a propeller airflow in a manner similar to that of the wing 13 by a method such as forming the arm 11 in a narrow plate shape and imparting an angle (twisting). A configuration that applies a rotational force is also included. Therefore, the shape of the wing and the mounting location are not limited to the illustrated structure.

The rotation of the disk main body 2 due to the throwing is maintained by the inertial force held by the disk main body 2, but is gradually attenuated by the air resistance of the resin film 5 covering the exposed part and surface of the frame 4.
The rotation of the disk body 2 has a gyroscopic effect of stabilizing the attitude of the aircraft during flight. For this reason, rotating the disk main body 2 is an important element for a throwing type flying disk.
The wing 13 that has received the downward airflow from the propeller 3 generates a rotational force that rotates the disk body 2 in the direction opposite to the propeller 3. The wing 13 acts to supplement the rotational force of the disc body 2 that is attenuated by air resistance and to keep the rotation. The rotation of the disk main body 2 has the effect of reducing the air resistance with respect to the stability of flight and the maintenance of buoyancy and the traveling direction. The flying disk according to the present embodiment can secure a stable flight posture and flight distance by utilizing the reaction force of the propeller for the rotation of the disk main body 2.
Further, since the propeller 3 is attached to the disk main body 2, when the propeller 3 rotates, the reaction force acts on the disk main body 2 and tries to rotate the disk main body 2. Although the said patent document 1 has a means which prevents rotation of the body by this reaction force, the flying disk 1 which concerns on this Embodiment has a structure which transmits the said reaction force to the disk main body 2 without negating. ing. In the flying disk according to the present embodiment, the reaction force accompanying the rotation of the propeller is also used for the rotation of the disk main body 2, thereby having an effect on the stability of the flight.

  On the other hand, the rotation of the propeller 3 does not generate a propulsive force in the horizontal direction, but has a buoyancy that tends to raise the disk body 2. Although the propeller 3 and the drive unit 9 used in the present embodiment do not have buoyancy enough to lift and lift the stationary disk body 2, the propeller 3 and the drive part 9 have a force enough to gently lower the disk body 2 to be dropped. It has been adjusted.

The flying disk 1 according to the present embodiment is provided with a cylindrical protective portion 14 on the upper surface of the disk body 2 so as to cover the outer periphery of the propeller 3. The protection part 14 is a part that looks like a trapezoidal protrusion protruding from the upper surface of the disk main body 2 when viewed from the side, and is provided so that the tip of the high-speed propeller 3 does not come into contact with the user. is there. Further, in this case, the airflow generated by the propeller 3 has an action of guiding the airflow to flow from top to bottom. The protection part 14 is formed lightweight.
Further, the protective part may be formed of a net-like member. In the case where the protective part is formed by a net-like member, it is possible to cover only the upper part or the entire periphery including the upper part in addition to the case where the protective part is formed in a cylindrical shape like the protective part 14. When the mesh member is used, it is possible to prevent the propeller from contacting the human body while reducing air resistance during flight.

In addition, the flying disk 1 according to the present embodiment uses the centrifugal force switch 12 described above as an example of the propeller 3 starting means, so that the propeller 3 starts to rotate when the flight starts and the propeller 3 starts when the flight ends. The rotation is stopped. However, the switching of the propeller 3 is not limited to this example.
For example, a physical quantity or change such as vibration, sound, distortion, acceleration, or the like generated in the disk main body when the flying disk 1 starts to be thrown is detected by a sensor, and the circuit is driven based on the detected signal, so that the propeller 3 is It may be rotated. In addition, in these controls, timer means for forcibly stopping the propeller 3 with the passage of a certain time can be provided, and the propeller 3 can be stopped when the end of flight cannot be determined by the sensor.
When the propeller 3 is stopped by a timer, the rotation of the propeller 3 may be started by a mechanical switch including the centrifugal force switch 12 without using a physical quantity detection sensor.

  The present invention is applicable to a flying object called a flying disk.
