Summary of the Invention

Problems to be Solved by the Invention

[0004] As described above, in the invention described in Patent Document 1 or Patent Document 2, the simple flying object falls by separating the propeller part and the base part due to an external impact such as a bullet. At this time, the propeller part or the base part only operates due to the inertia from the previous flight and the external impact such as a bullet. Therefore, even if the propeller part and the base part are separated due to an external impact such as a bullet, they simply move apart and do not actively and forcefully separate in opposite directions. Thus, it lacks dynamism and visual impact.

[0005] The present invention has been developed against the background of the above problems. That is, the present invention is a simple flying object that separates and falls under impact, and an object of the present invention is to provide a simple flying object in which the propeller part and the base part actively, forcefully, and violently separate in opposite directions when falling.

Means for Solving the Problems

[0006] As a result of intensive studies, the inventor of the present invention temporarily couples a plurality of propeller parts and a base part, and disposes a spring part having a repulsive force at the temporary coupling part, so that when the propeller part and the base part are separated in the air, they actively, forcefully, and violently separate in opposite directions, and it has been found that a visual impact can be obtained. The present invention has been made based on this finding.

[0007] The present invention is a simple flying object A that falls under an external impact, and the simple flying object A includes a base part 1 and a plurality of propeller parts 2 that can be separated from the base part 1 by impact. The propeller part 2 and the base part 1 are temporarily coupled, and a spring part S is disposed between the propeller part 2 and the base part 1. The spring part S is disposed in a state where the propeller part 2 and the base part 1 are elastically pressed.

[0008] In the present invention, a propeller part side temporary coupling part 2A is provided on the propeller part 2, a base part side temporary coupling part 1A is provided on the base part 1, and the propeller part 2 and the base part 1 are temporarily coupled via the propeller part side temporary coupling part 2A and the base part side temporary coupling part 1A. The simple flying object A is as described above.

[0010] The present invention resides in the simple flying object A described above, in which the propeller part 2 and the base part 1 are temporarily joined by bayonet connection.

[0011] The present invention resides in the simple flying object A described above, in which the propeller part 2 and the base part 1 are temporarily joined by pin connection.

[0012] The present invention resides in the simple flying object A described above, in which the propeller part 2 and the base part 1 are temporarily joined by press-fitting connection.

[0013] The present invention resides in the simple flying object A described above, in which the propeller part 2 and the base part 1 are temporarily joined by magnetic attachment connection. The present invention resides in the simple flying object A described above.

[0014] The present invention resides in the simple flying object A described above, in which a power source 4 and a control part 6 for controlling the propeller part 2 are provided in the base part 1, the propeller part 2 is composed of a motor body 3 coupled to the power source 4 and a propeller body 21 attached to the shaft of the motor body 3, a base part side contact 11a is provided in the base part 1, a propeller part side contact 23 is provided in the propeller part 2, and the power source 4 and the motor body 3 are electrically connected by contact between the base part side contact 11a and the propeller part side contact 23, and when the temporary connection between the base part 1 and the propeller part 2 is disengaged due to impact, the base part side contact 11a and the propeller part side contact 23 are separated at the same time.

[0015] The present invention resides in the simple flying object A described above, in which the base part 1 is a substantially rectangular housing, arm parts 11 extend horizontally from the upper ends of the four corners of the base part 1, the propeller part 2 is attached to the tip of each arm part 11, and the propeller part 2 is attached so as to support the arm part 11 from below.

[0016] The present invention resides in the simple flying object A described above, wherein the propeller unit 2 has a propeller body 21 and a frame unit 22 for protecting the propeller body 21, and the frame unit 22 has a motor body receiving portion 22a that houses a motor body 3 connected to the axis of the propeller body 21 from below, three beam portions 22b that extend obliquely upward and outward from the motor body receiving portion 22a, and a circular outer frame 22c that does not contact the propeller body 21 supported by the beam portions 22b.

[0017] Further, the present invention may be a suitable combination of the above.

Effect of the Invention

[0018] In the simple flying object A, since at least one of the propeller units 2 separates from the base unit 1 and falls when the simple flying object A receives an impact from the outside, for example, it can be used in a game of shooting down the simple flying object A by shooting, hitting, etc. Also, in the simple flying object A, the propeller unit 2 and the base unit 1 are temporarily joined, and the spring portion S disposed between the propeller unit 2 and the base unit 1 is disposed in a state of being elastically compressed by the temporary joining of the propeller unit 2 and the base unit 1. When the simple flying object A receives an impact and the propeller unit 2 and the base unit 1 separate in the air, they separate vigorously and violently due to the repulsive force of the spring portion S, and a visual impact can be obtained. Therefore, when shooting down the simple flying object A, it is easier to visually recognize that an object has hit the simple flying object A, and a sense of exhilaration can be obtained. In addition, when the base unit 1 and the propeller unit 2 are separated, by attaching and temporarily joining the base unit 1 and the propeller unit 2 again, flight can be easily performed any number of times.

[0019] Also, since there are a plurality of propeller units 2, the separation of the propeller units 2 from the base unit becomes more visually recognizable. Also, a sense of exhilaration and excitement of shooting down the simple flying object A in pieces can be obtained.

[0020] In the simple flying object A, the propeller unit 2 and the base unit 1 are temporarily joined by any one of a locking connection, a bayonet connection, a pin connection, a press fit connection, or a magnetic attachment connection. When the base unit 1 and the propeller unit 2 are separated, the user can easily attach the propeller unit 2 to the base unit 1 again and temporarily join them. Also, when they are temporarily joined by any one of a locking connection, a bayonet connection, a press fit connection, or a magnetic attachment connection, loss of parts and the like can be prevented.

[0021] In the simple flying object A, since the power source 4 is provided in the base unit 1, the propeller unit 2 can be driven using the power source 4 as a power source. When the power source 4 is a battery, it is easy to replace.

[0022] In the simple flying object A, since at least one of the propeller units 2 separates from the base unit 1 and falls when the simple flying object A collides with another object, for example, it can also be used in a game where the simple flying object A is operated to avoid obstacles.

[0023] In the simple flying object A, the arm portion 11 extends from the base unit 1, and the propeller unit 2 is attached so as to support the arm portion 11 from below. Thus, the lift force generated in the propeller unit 2 is directly transmitted to the base unit 1. As a result, the base unit 1 is accurately supported and the flight of the simple flying object A becomes stable.

[0024] In the simple flying object A, the propeller unit 2 has a propeller body 21 and a frame portion 22 for protecting it. The frame portion 22 has a motor body receiving portion 22a that houses the motor body 3 connected to the axis of the propeller body 21 from below, three beam portions 22b that extend obliquely upward outward from the motor body receiving portion 22a, and a circular outer frame 22c that does not contact the propeller body 21 supported by the beam portions 22b. By having these, the propeller body 21 is reliably protected, and even when the simple flying object A repeatedly flies and falls, damage to the propeller body 21 can be prevented.

DETAILED DESCRIPTION OF THE INVENTION

[0026] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings as necessary. In the drawings, the same reference numerals are assigned to the same elements, and duplicate descriptions are omitted. In addition, the positional relationships such as up, down, left, and right are based on the positional relationships shown in the drawings unless otherwise specified. Furthermore, the dimensional ratios in the drawings are not limited to the illustrated ratios.

[0027] FIGS. 1(A) and 1(B) are side views showing a simple flying object A. FIG. 1(A) shows a state in which the base portion 1 and the propeller portion 2 are attached. The simple flying object A is composed of a base portion 1 and a propeller portion 2. The simple flying object A can fly freely in the vertical direction, horizontal direction, or diagonal direction by driving the propeller unit 2. FIG. 1(B) is a diagram showing the state before attaching the base unit 1 and the propeller unit 2. In addition, the right propeller unit 2 is shown in the attached state. As shown in FIG. 1(B), the propeller unit 2 is attached from the lower side of the base unit 1.

[0028] FIG. 2 is a top view showing the simple flying object A. As shown in the figure, in this embodiment, four propeller units 2 are attached to the base unit 1.

[0029] The base unit 1 is a substantially rectangular housing. Arm portions 11 extend horizontally from the upper ends of the four corners of the base unit 1, and the propeller units 2 are attached to the tips of the respective arm portions 11. The base unit 1 incorporates a power source 4, a control unit 6 for controlling the propeller unit 2, a conduction wire 5 for supplying power to the propeller unit 2, etc., and these are electrically connected (see FIG. 1A).

[0030] The base unit 1 and each propeller unit 2 are in a state of a weak connection, so-called temporary connection, such that their attachment may become detached due to an external impact. Specifically, the base unit 1 and the propeller unit 2 are temporarily connected by the engagement of a claw 24 provided as a propeller unit side temporary connection portion 2A and a receiving portion provided as a base unit side temporary connection portion 1A. That is, the temporary connection between the base unit 1 and the propeller unit 2 is by a locking connection.

[0031] Here, a spring portion S such as a coil spring is disposed between the base unit side temporary connection portion 1A and the propeller unit side temporary connection portion 2A. Due to the temporary connection between the base unit 1 and the propeller unit 2, the spring portion S is in a compressed state and is elastically pressed. Here, the spring portion S may be fixed to the base unit side temporary connection portion 1A, or may be fixed to the propeller unit side temporary connection portion 2A. Also, it may be in a free state without being fixed to either. In this case, the spring part S will also protrude alone. The spring part S is provided with a recess serving as a spring receiving part S1 in the base part side temporary coupling part 1A or the propeller part side temporary coupling part 2A, and is arranged so as to fit into the recess, thereby facilitating the positioning of the spring part S itself.

[0032] Inside the base part 1, a power source 4, for example a battery, is arranged. The simple flying object A is driven by these power sources 4 (see Fig. 1(A)). A battery can be preferably used as the power source 4 provided in the base part 1, and it can be replaced even when the power source 4 is exhausted. Also, by using a storage battery as the battery, it becomes possible to charge and use it repeatedly.

[0033] The control part 6 is provided with a receiving part for receiving an external operation signal and a circuit for controlling the driving of each of the plurality of propeller parts 2 according to the operation signal received by the receiving part. By the control part 6, each propeller part 2 starts and stops rotating, and changes the rotation speed and the like. The operation signal received by the receiving part is transmitted from an external controller (not shown) at a distance from the simple flying object A, and the attitude and flight direction of the simple flying object A are controlled by the driving of the propeller. In addition, for transmitting the operation signal, a remote controller can be used in the same way as a known radio control.

[0034] Fig. 3 is a bottom view showing the arm part 11. The arm part 11 extends outward from the corner part of the base part 1. Each arm part 11 incorporates a conduction wire 5 for energizing the motor body 3 of the propeller part 2, and a base part side contact point 11a which is the end of the conduction wire 5 is exposed on the lower side of the end of each arm part 11 (see Fig. 1). When the base part side contact point 11a comes into contact with the propeller part side contact point 23 provided on the propeller part 2 side, the power source 4 and the motor body 3 are electrically connected, and power is supplied to the motor body 3.

[0035] FIG. 4 is a partial cross-sectional view showing the temporary coupling portion 1A on the base portion side, showing the X-X cross-section in FIG. 3. Note that the state where the propeller portion side 2A is attached is shown. At the tip of each arm portion 11, a pair of receiving portions, which are the temporary coupling portions 1A on the base portion side, are provided. The receiving portions are provided to face the propeller side so that a pair of claws 24, which are the temporary coupling portions 2A on the propeller portion side, can engage.

[0036] FIG. 5 is an explanatory view showing the propeller portion 2. A part is shown in cross-section. Since each of the plurality of propeller portions 2 has the same configuration, one of them will be described here as an example. The propeller portion 2 includes a propeller body 21, a motor body 3 provided on the axis of the propeller body 21, and a conduction wire 5 for contacting and conducting with the base portion side contact 11a provided on the arm portion 11 of the base portion 1 described above.

[0037] The propeller portion 2 has a propeller body 21 that generates lift by rotating, and a frame portion 22 for protecting it. The frame portion 22 includes a motor body receiving portion 22a that houses the motor body 3 connected from below to the axis of the propeller body 21, a plurality of (here, three) beam portions 22b that extend obliquely upward outward from the motor body receiving portion 22a, and a circular outer frame 22c that does not contact the propeller body 21 supported by the beam portions 22b. Further, the outer frame 22c is provided with an extension portion 22d that protrudes toward the base portion 1.

[0038] The beam portions 22b and the extension portion 22d house a conduction wire 5 that conducts with the motor body 3. On the upper side of the extension portion 22d, the end of the conduction wire 5 is exposed as a propeller portion side contact 23 for contacting and conducting with the base portion side contact 11a provided on the base portion 1. Since the propeller body 21 is protected by these structures, it is possible to prevent damage to the propeller body 21 even when the simple flying object A repeats flight and fall.

[0039] FIG. 6 is a partial cross-sectional view showing the temporary coupling portion 1A on the base portion side, and shows the X-X cross-section in FIG. 3. Note that the state where the temporary coupling portion 2A on the propeller portion side is separated is shown. A pair of claws 24, which are the above-described temporary coupling portion 2A on the propeller portion side, are provided on the extending portion 22d. When temporarily fixing the base portion 1 and the propeller portion 2, the claw 24 is inserted into the temporary coupling portion 1A on the base portion side, and the claw 24 is hooked on the hooking portion provided in the temporary coupling portion 1A on the base portion side.

[0040] Here, the hole of the temporary coupling portion 1A on the base portion side is provided with a size such that it does not bind firmly. Specifically, as shown in FIG. 4, for example, it is provided such that the width of the hooking portion claw 24 is about half the width of the temporary coupling portion 1A on the base portion side where it is locked. Thereby, when the simple flying object A receives an impact from the outside and the propeller portion 2 is displaced outward (leftward in FIG. 4) with respect to the base portion 1, the inner claw 24 comes off from the hooking portion. Then, the propeller portion 2 loses its balance and tilts downward on the inner side (rightward in FIG. 4) and falls. As a result, the outer claw 24 also shifts inward and comes off from the hooking portion, and the propeller portion 2 and the base portion 1 are completely separated, resulting in the state of FIG. 6. Conversely, when the simple flying object A receives an impact from the outside and the propeller portion 2 is displaced inward (rightward in FIG. 4) with respect to the base portion 1, the outer claw 24 comes off from the hooking portion. Thereby, the propeller portion 2 falls with the outer side (leftward in FIG. 4) on the lower side, and thereby the inner claw 24 also comes off from the hooking portion. As a result, the state of FIG. 6 is similarly obtained.

[0041] In addition, a spring receiving portion S1 described above is provided on the extending portion 22d. The spring receiving portion S1 has a shape corresponding to the spring portion S.

[0042] When attaching the propeller portion 2 to the base portion 1, the arm portion 11 of the base portion 1 is attached so that the extending portion 22d of the propeller portion 2 supports from below. At this time, the claws 24 of the propeller part side temporary coupling part 2A are inserted by the end part of the opening of the base part side temporary coupling part 1A. By hanging the returns of the pair of claws 24 on the catching parts of the base part side temporary coupling part 1A respectively, the base part side temporary coupling part 1A and the propeller part side temporary coupling part 2A are locked.

[0043] At this time, the spring part S disposed between the base part 1 and the propeller part 2 is elastically pressed in a compressed state by both of them. By maintaining the elastic state of the spring part S due to the locking of the base part side temporary coupling part 1A and the propeller part side temporary coupling part 2A, in the state where the base part 1 and the propeller part 2 are temporarily coupled, a force in the direction of separating from each other by the spring part S is accumulated between the two.

[0044] When the propeller part side temporary coupling part 2A and the base part side temporary coupling part 1A are temporarily coupled, the propeller part 2 is accurately positioned with respect to the base part 1. At this time, since the base part 1 and the propeller part 2 are accurately positioned, the base part side contact point 11a provided on the lower surface of the arm part 11 and the propeller part side contact point 23 provided on the upper surface of the extending part 23 are in contact, and electric power is supplied from the power source 4 of the base part 1 to the propeller part 2. Thereby, even if the user is, for example, a beginner or a child, it becomes possible to easily attach the base part 1 and the propeller part 2 and perform flight again.

[0045] By the way, the extending part 22d of the propeller part 2 supports the arm part 11 of the base part 1 from below upward By attaching it in such a way, the lift generated in the propeller part 2 is directly transmitted to the base part 1. In this case, the base part 1 is accurately supported by the supporting force, and the flight of the simple flying object A is stabilized. On the contrary, when the structure is such that the arm part 11 of the base part 1 supports the extending part 22d of the propeller part 2 from below, lift is applied only to the propeller part 2, and the base part 1 is supported only by the locking connection of the temporary coupling part. In this case, the propeller part 2 becomes more likely to separate from the base part 1, and the game property is improved.

[0046] The simple flying object A is driven by obtaining power from the power source 4. For example, among the four propeller units 2, the propeller bodies 21 of those on the diagonal rotate in the same direction, and the propeller bodies 21 of adjacent propeller units 2 rotate in opposite directions, so that the simple flying object A can perform floating, descending, or hovering without horizontal movement. Specifically, by increasing the rotation speed of the propeller body 21, the lift force increases, and the simple flying object A ascends. At this time, each propeller body 21 rotates at the same rotation speed. By changing the rotation speed of the propeller body 21, it can be tilted.

[0047] Movement or rotation is performed by making the rotation speeds of the propeller bodies 21 of each propeller unit 2 different. Specifically, for example, in the case of movement, by increasing the rotation speeds of the two propeller bodies 21 behind the traveling direction compared to the rotation speeds of the two propeller bodies 21 on the traveling direction side, the simple flying object A moves in the traveling direction. In the case of rotation, rotation is performed by increasing the rotation speeds of the propeller bodies 21 of the two propeller units 2 arranged diagonally and rotating in the rotation direction compared to the rotation speeds of the other two propeller bodies 21.

[0048] Figure 7 is an explanatory diagram showing the state where the propeller unit 2 and the base unit 1 are separated. The simple flying object A maintains a horizontal state during flight. When an external impact is applied to the simple object A during flight, the balance is disrupted and the posture collapses. Then, the direction of the lift force applied from the propeller unit 2 to the base unit 1 changes, for example, a torsional force is applied between the propeller unit 2 and the base unit 1, and at least a part of the propeller unit 2 and the base unit 1 are separated.

[0049] When the propeller unit 2 and the base unit 1 are separated, the spring part S is released from the elastic state. Due to the restoring force (i.e., elastic force) of the released spring part S, the propeller unit 2 is vigorously ejected from the base unit 1. That is, the base unit 1 and the propeller unit 2 are actively and violently separated. As a result, the separation becomes visually more intense, and a dynamic and exciting feeling can be obtained.

[0050] Furthermore, when some of the propeller parts 2 are separated from the base part 1, the attitude of the simple flying object A cannot be maintained, and in some cases, the other propeller parts 2 and the base part 1 may be sequentially separated in a chain reaction. Even in this case, a plurality of spring parts S that are elastically pressed between the base part side temporary coupling part 1A and the propeller part side temporary coupling part 2A are released, and due to this restoring force, the base part 1 and the propeller part 2 are vigorously separated.

[0051] When the base part 1 and the propeller part 2 are separated, the base part side contact point 11a and the propeller part side contact point 23 are separated and conduction is established, so that the rotation of the propeller body 21 stops. As a result, even if the simple flying object A surely falls, it is possible to prevent injuries in the case where the fallen propeller body 21 hits a person.

[0052] The simple flying object A of the present invention is mainly for use in games. Various games can be considered using the simple flying object A. For example, there is a game in which a soft ball made of synthetic resin is thrown, or a ball or a bullet such as a BB bullet is made to collide with the flying simple flying object A by a method such as using an air gun, and the purpose is to knock it down by an impact from the outside. In this case, it can be considered to be a game in which competing to hit the simple flying object A with another object.

[0053] When the simple flying object A is impacted, since the propeller part 2 can be separated from the base part 1, when the simple flying object A is knocked down, it is visually easy to tell that an object has hit the simple flying object A, and a refreshing feeling can be obtained. In addition, since there are a plurality of propeller parts 2, the separation of the propeller parts 2 from the base part 1 occurs in multiple directions, and the visual impact is extremely large. Also, it is possible to obtain a refreshing feeling and an exciting feeling of knocking down the simple flying object A in pieces.

[0054] Here, other embodiments will be described. In the above embodiment, the temporary coupling portion 2A on the propeller portion side was fixed, but the temporary coupling portion 2A on the propeller portion side may be made movable so as to protrude by the supply of power from the power source 4 and retract when the supply of power is cut off. For example, FIG. 8(A) is an explanatory diagram showing a simple flying object A according to another embodiment, showing a state in which the base portion 1 and the propeller portion 2 are attached. In the present embodiment, the temporary coupling portion 2A on the propeller portion side includes an opening 24a provided so as to face the base portion 1 side, and a rod-shaped portion 24b that protrudes by being supplied with power from the power source 4 toward the inside of the opening 24a. The rod-shaped portion 24b retracts when the supply of power is cut off. Further, the temporary coupling portion 1A on the base portion side is a rod-shaped portion corresponding to the opening 24a, and has a hole 12a corresponding to the rod-shaped portion 24b.

[0055] FIG. 8(B) is an explanatory diagram showing the simple flying object A according to another embodiment, showing a state in which the base portion 1 and the propeller portion 2 are separated. When the temporary coupling portion 1A on the base portion side is inserted into the opening 24a of the temporary coupling portion 2A on the propeller portion side, the contact point 23 on the propeller portion side and the contact point 11a on the base portion side come into contact, and power is supplied to the rod-shaped portion 24b. As a result, the rod-shaped portion 24b protrudes and is inserted into the hole 12a of the temporary coupling portion 1A on the base portion side. As a result, the propeller portion 2 is locked and temporarily coupled to the base portion 1. When an external impact is applied to the simple flying object A in this state, a force is applied between the base portion 1 and the propeller portion 2, and the temporary coupling between the temporary coupling portion 1A on the base portion side and the temporary coupling portion 2A on the propeller portion side is disengaged. Specifically, when the power is cut off, the rod-shaped portion 24b, which is the temporary coupling portion 2A on the propeller portion side, retracts and comes out of the hole 12a. As a result, the elastic force of the spring portion S is exerted, and the base portion 1 and the propeller portion 2 are actively separated in a strongly opposing direction. This separation is dynamic and has a large visual impact.

[0056] Also, the temporary coupling between the base part 1 and the propeller part 2 may use protrusions. FIGS. 9(A) and 9(B) are explanatory views showing a simple flying object A according to still another embodiment. FIG. 9(A) shows a state in which the base part 1 and the propeller part 2 are attached. FIG. 9(B) shows a state in which the base part 1 and the propeller part 2 are separated. In the present embodiment, as the temporary coupling part 2A on the propeller part side, a cylindrical part 24c having a diameter-expanded part 24d with a diameter-expanded tip is provided, and as the temporary coupling part 1A on the base part side, a hole part corresponding to the cylindrical part 24c is provided. In the hole part, a protrusion part 12b protruding inward is provided in the middle thereof. The cylindrical part 24c, particularly the diameter-expanded part 24d, has elasticity. A spring part S is provided at the bottom of the hole part of the temporary coupling part 1A on the base part side, and a spring receiving part S1 is provided at the tip of the cylindrical part 24c. To attach the base part 1 and the propeller part 2, the cylindrical part 24c is inserted into the hole part so that the diameter-expanded part 24d straddles the protrusion part 12b and is inserted, whereby the propeller part 2 and the base part 1 are temporarily coupled.

[0057] Also, the locking coupling between the base part 1 and the propeller part 2 may be by a bayonet coupling that locks using rotation. Specifically, with the pin part P inserted into the hole part, the propeller part 2 may be rotated with respect to the base part 1 so that the pin part P and the key part 12 engage with each other. FIG. 10(A) is an explanatory view showing a simple flying object A according to another embodiment, showing a state in which the propeller part 2 is attached to the base part 1. For convenience of explanation, parts other than the key part 12c and the pin part P are shown in cross section. Also, FIG. 11(A) is an explanatory view showing the state of temporary coupling in FIG. 10(A), showing a state of viewing the temporary coupling part 1A on the base part side from below. In addition, the pin part P is shown added. In this embodiment, the temporary coupling portion 1A on the base portion side is a hole portion provided on the side facing the propeller portion 2, and a spring portion S is provided on the bottom surface. Further, two key portions 12c having an L shape in a top view are provided on the inner wall at a position spaced apart from the bottom surface. The temporary coupling portion 2A on the propeller portion side is a pin portion P having an enlarged head at its tip. Two temporary coupling portions 2A on the propeller portion side are provided at positions corresponding to the key portions 12c. To temporarily couple the base portion 1 and the propeller portion 2, with the temporary coupling portion 2A on the propeller portion side inserted into the temporary coupling portion 1A on the base portion side, the propeller portion 24 is rotated in a predetermined direction. When it is rotated until the pin portion P abuts against the key portion 12c, the enlarged head is caught by the key portion 12, and the pin portion P is locked to the key portion 12c. Thereby, the base portion 1 and the propeller portion 2 are temporarily coupled. At this time, the spring portion S provided at the bottom of the temporary coupling portion 1A on the base portion side is in a compressed state.

[0058] FIG. 10(B) is an explanatory view showing a simple flying object A according to another embodiment, showing a state where the temporary coupling is released. For convenience of explanation, parts other than the key portion 12c and the pin portion P are shown in cross section. FIG. 11(B) is an explanatory view showing the state of the temporary coupling in FIG. 10(B), showing the state of the temporary coupling portion 1A on the base portion side and the pin portion P as viewed from below. In addition, the pin portion P is shown added. When an external impact is applied to the simple flying object A and the propeller portion 2 is rotated in a direction opposite to the predetermined direction, the pin portion P moves to a position disengaged from the key portion 12c, and the temporary coupling is released. As a result, the propeller portion 2 becomes free with respect to the base portion 1.

[0059] FIG. 10(C) is an explanatory view showing a simple flying object A according to another embodiment, showing a state where the spring portion S is released. When the temporary coupling between the base portion 1 and the propeller portion 2 is released, the spring portion S that has been compressed is released. Thereby, the base portion 1 and the propeller portion 2 are violently separated. In the case of this embodiment, since it is temporarily joined by bayonet coupling as described above, when a force is applied in the rotational direction upon receiving an impact, the base portion 1 and the propeller portion 2 are separated, which is a characteristic. Also, the propeller portion 2 is more firmly attached to the base portion 1, making it more difficult to knock down the simple flying object A. As a result, it is possible to bring about a change in the gameplay.

[0060] In the above embodiment, the temporary joining between the base portion 1 and the propeller portion 2 was by locking coupling, but it may also be by pin coupling. FIG. 12 is an explanatory diagram showing a temporary joining portion 1A on the base portion side and a temporary joining portion 2A on the propeller portion side according to another embodiment. In this case, holes communicating with the propeller portion 2 and the base portion 1 are provided, and they are temporarily joined by inserting a coupling pin 24e. The coupling pin 24e is press-fitted into the base portion 1 and the propeller portion 2. Thereby, the base portion 1 and the propeller portion 2 are separated by an external impact.

[0061] Also, in the above embodiment, the temporary joining between the base portion 1 and the propeller portion 2 was by locking, but it may also be by magnetic attachment coupling. FIG. 13 is a bottom view showing an arm portion 11 according to another embodiment. In this case, for example, inside the end portion of each arm portion 11, a magnet 7 for magnetically attaching the propeller portion 2 is embedded on the lower side. And in the extending portion 22d of the propeller portion 2, a magnetic body (not shown) is built in so as to face the magnet 7 provided on the arm portion 11 of the base portion 1. Here, for the magnetic body, for example, a thin iron plate can be suitably used. When the arm portion 11 of the base portion 1 and the extending portion 22d of the propeller portion 2 are brought close to each other, a magnetic attraction force acts between the magnet 7 and the magnetic body, and the two are temporarily joined. In this case, it is necessary to set the magnetic attraction force to be greater than the elastic force of the spring portion S. In this embodiment, since the base portion 1 and the propeller portion 2 are attached by magnetic attachment, the base portion 1 and the propeller portion 2 can be easily assembled.

[0062] In addition, in the temporary coupling by magnetic attachment between the base portion 1 and the propeller portion 2, an electromagnet may be used instead of the permanent magnet 7. In that case, the electromagnet will be connected to the power source 4. FIG. 14 is an explanatory diagram showing a simple flying object A according to another embodiment. In this embodiment, a touch sensor 10 is provided so as to be exposed outside the base portion 1. The touch sensor 10 is electrically connected to the control unit 6, and touching the touch sensor 10 switches the on / off of the power supply from the power source 4. The touch sensor 10 is supplied with power from the power source 4, that is, it shares the power source with the motor body 3 of the propeller portion 2. Similarly, the electromagnet 9 is also supplied with power from the power source 4, and shares the power source with the touch sensor 10 and the motor body 3.

[0063] FIG. 15 is an explanatory diagram showing a state in which the propeller portion 2 and the base portion 1 according to another embodiment are separated. By the touch sensor 10 switching the on / off of the power supply, the power supplies to the propeller portion 2 and the electromagnet 9 are switched synchronously. That is, when something touches the touch sensor 10 of the simple flying object A in the flying state, the power supply to the motor body 3 of the propeller portion 2 is immediately stopped (that is, the conduction is broken), and the drive of the propeller portion 2 stops. At the same time, the power supply to the electromagnet 9 is stopped, the magnetic attraction force acting between the base portion 1 and the propeller portion 2 is lost, and the base portion 1 and the propeller portion 2 are separated. Therefore, by touching the sensor 10 of the simple flying object A during flight, the drive of the propeller stops and at the same time the four propeller portions 2 and the base portion 1 are separated and each falls. When all the propeller portions 2 are separated from the base portion 1 and the simple flying object A falls, a greater sense of exhilaration can be obtained. The sensor 10 may be configured such that, for example, the drive of only one propeller stops, rather than all of them.

[0064] Furthermore, as another embodiment, press-fitting can also be used for attaching the base portion 1 and the propeller portion 2. FIGS. 16(A) and 16(B) are explanatory views showing a simple flying object A according to another embodiment. FIG. 16(A) shows a state in which the base portion 1 and the propeller portion 2 are attached. FIG. 16(B) shows a state before the base portion 1 and the propeller portion 2 are attached. In the simple flying object A, a concave portion 13 is provided in the arm portion 11, and a convex portion 12 is provided in the extending portion 22d. When attaching the base portion 1 and the propeller portion 2, the convex portion 12 is press-fitted into the concave portion 13. This press-fitting relationship is preferably such that it can be easily detached when subjected to an impact. However, it is necessary to set the press-fitting force to be greater than the elastic force of the spring portion S. By using fitting for attaching the base portion 1 and the propeller portion 2, the positioning of the propeller portion 2 with respect to the base portion 1 is surely performed. Also, even if the user is a child, it becomes possible to easily attach the base portion 1 and the propeller portion 2.

[0065] As described above, the preferred embodiments of the present invention have been described, but the present invention is not limited to the above embodiments. It is sufficient if the principle can be applied.

[0066] The spring portion S is not limited to a coil spring, and various springs such as a leaf spring can be preferably used as long as it can exhibit an elastic force.

[0067] In the locking between the base portion 1 and the propeller portion 2, it is arbitrary whether the base portion side temporary coupling portion 1A or the propeller portion side temporary coupling portion 2A is the claw 24 or the receiving portion. Similarly, the shapes and numbers of the claw 24 and the receiving portion are also arbitrary.

[0068] In the present embodiment, there are four arm portions 11 extending from the base portion 1 and four propeller portions 2 attached to the arm portions 11, respectively, but the number and attachment positions are not particularly limited.

[0069] In the present embodiment, the shapes of the base portion 1 and the propeller portion 2 are as described above, but are not limited thereto. For example, it is possible to appropriately make changes such as making the base portion 1 spindle-shaped and increasing or decreasing the number of beam portions 22b of the propeller portion 2.

[0070] In the present embodiment, engagement or the like is used for attaching the base portion 1 and the propeller portion 2, but other methods may be used, or a combination thereof may be used as appropriate. Further, in the arm portion 11 and the extension portion 22d, appropriate unevenness and ribs can be provided for positioning in the attachment of the base portion 1 and the propeller portion 2. Furthermore, in the present embodiment, the propeller portion 2 is attached from below the base portion 1, but a structure in which the propeller portion 2 is attached from the side of the base portion 1 may also be used. In the present embodiment, in FIGS. 1, 5, 8, 14, etc., the propeller portion 2 includes a beam portion 22b, and a conduction wire 5 is built in the beam portion 22b. However, in the case of a structure without the beam portion 22b, it is also possible to adopt a wiring structure that does not pass through the inside of the beam portion 22b.

Industrial Applicability

[0071] The simple flying object A can be widely used in various games. In the simple flying object A, when impacted, the base portion 1 and the propeller portion 2 are violently separated, resulting in a stronger impact. As a result, a sense of exhilaration and excitement can be obtained. Also, even if the base portion 1 and the propeller portion 2 are separated, they can be easily reassembled.
