[0004] The first Jetman Yves Rossy, [online]. [Retrieved on 27 September, 2023], Retrieved from the internet :<URL: https: / / yvesrossy.com / >

[0005] The above-mentioned flight devices are primarily attached to the pilot's upper body. Therefore, when flying using the flight devices, the pilot's body (especially the legs) from the waist down is suspended in mid-air. This poses a problem in that, unlike when standing on the ground, the freedom and naturalness of physical movement are significantly limited.

[0006] The present invention has been made in consideration of the above-mentioned circumstances, and aims to provide a reaction force mechanism and flight system that allows a pilot to ensure freedom and naturalness in their physical movements during flight.

[0007] <1> The reaction force mechanism of aspect 1 of the present invention is a reaction force mechanism that is attached to a pilot wearing a flying device, and is characterized by comprising a first part that is attached to a part of the pilot's leg, a second part that is attached to the pilot's upper body or waist, and a third part that connects the first part and the second part.

[0008] According to the invention of Aspect 1, the reaction force mechanism is attached to a pilot wearing the flight device. The reaction force mechanism further includes a first section attached to a portion of the pilot's leg, a second section attached to the pilot's upper body or waist, and a third section connecting the first and second sections. As a result, when a pilot to which the reaction force mechanism is attached extends his / her leg, tension is generated in the third section. This tension allows the pilot to receive a reaction force from the first section to his / her leg. As a result, even when the pilot is flying using the flight device and the pilot's legs are suspended in mid-air, i.e., the pilot's feet are not in contact with the ground, the pilot can extend his / her legs and receive a force similar to the reaction force received from the ground when the pilot is standing on the ground. Therefore, even when the pilot's feet are not in contact with the ground, the pilot can apply force to his / her legs by bracing himself / herself using the reaction force mechanism. This ensures freedom and naturalness of the pilot's physical movement while flying. That is, for example, it is possible to more easily stabilize the pilot's posture while flying. Alternatively, it can make it easier for the pilot to change his / her posture during flight. Furthermore, by attaching such a reaction force mechanism to the pilot, it becomes easier to use the pilot's body movements to give instructions regarding the operation of the flying device.

[0009] <2> A reaction force mechanism according to aspect 2 of the present invention is the reaction force mechanism according to aspect 1, characterized in that the first part is fixed to the sole of the operator's foot.

[0010] According to the invention of Aspect 2, the first section is fixed to the soles of the pilot's feet. This allows the pilot to apply force to his legs as if bracing himself during flight, with the same sensation as if he were standing on the ground. This makes it easier to ensure greater freedom and naturalness in the pilot's physical movements.

[0011] <3> A reaction force mechanism according to aspect 3 of the present invention is the reaction force mechanism according to aspect 1 or 2, characterized in that the first part is fixed to the knee of the operator.

[0012] According to the invention of Aspect 3, the first section is fixed to the knee of the pilot. This reduces the number of devices attached to the part of the pilot below the knee. Therefore, for example, when the pilot lands during flight, the pilot can easily use the soles of his / her feet freely.

[0013] <4> A reaction force mechanism according to aspect 4 of the present invention is the reaction force mechanism according to any one of aspects 1 to 3, characterized in that the second part is fixed to the shoulder of the operator.

[0014] According to the invention of Aspect 4, the second section is fixed to the pilot's shoulder. As a result, the reaction force caused by the pilot extending his / her legs is applied to the pilot's shoulder via the second section. This allows, for example, the force of the pilot's legs to assist the pilot's back muscles. Therefore, for example, when the pilot has relatively low muscle strength, it is possible to more easily assist the pilot's physical movement during flight.

[0015] <5> A reaction force mechanism according to aspect 5 of the present invention is a reaction force mechanism according to any one of aspects 1 to 3, characterized in that the second part is fixed to the waist of the operator.

[0016] According to the invention of aspect 5, the second section is fixed to the waist of the pilot. This makes it possible to reduce the size of the reaction force mechanism, for example. Therefore, it is possible to reduce the weight of the reaction force mechanism, for example. Furthermore, it is possible to make it easier for the pilot to move their body while walking on the ground or flying.

[0017] <6> A reaction force mechanism according to aspect 6 of the present invention is a reaction force mechanism according to any one of aspects 1 to 3, characterized in that the second part is fixed to the flight device.

[0018] According to the sixth aspect of the present invention, the second section is fixed to the flight device. This allows the pilot to apply a pulling force to the flight device by, for example, extending his / her legs. The force applied by the pilot in this manner can be used, for example, to control the flight device. That is, for example, the thrust of the flight device can be changed depending on the magnitude of the force with which the pilot pulls the flight device via the reaction force mechanism. Furthermore, for example, the pilot can change the attitude of the flight device by changing its attitude using the reaction force mechanism. In this way, by allowing the pilot to control the flight device using his / her legs, the pilot can use his / her hands freely during flight. Therefore, the pilot can perform some task while remaining in the air using the flight device.

[0019] <7> A reaction force mechanism according to aspect 7 of the present invention is a reaction force mechanism according to any one of aspects 1 to 3, characterized in that the second part is fixed to a full harness worn by the pilot.

[0020] Here, the pilot may wear a flight device via a full harness. During flight, the pilot is suspended by the full harness. The pilot's weight is then applied to the base of the pilot's legs via the full harness. This can compress the base of the pilot's legs, causing pain. Furthermore, prolonged suspension can cause congestion in the base of the pilot's legs. Therefore, according to the seventh aspect of the invention, the second part of the reaction force mechanism is attached to the full harness worn by the pilot. This allows the pilot, wearing a reaction force mechanism, to extend his or her legs, so that the weight of the pilot applied to the base of the pilot's legs is applied to the first part of the reaction force mechanism. This reduces pressure on the base of the pilot's legs. Therefore, pain and congestion in the base of the pilot's legs can be reduced. Furthermore, attaching such a reaction force mechanism to the pilot reduces the burden on the pilot's body, contributing to extending the pilot's flight time. In addition, by having the pilot wear the flight device via a full harness, it becomes easier to put on and take off the flight device.

[0021] <8> A flight system according to aspect 8 of the present invention is characterized by comprising a flight device and a reaction force mechanism according to any one of aspects 1 to 7.

[0022] According to the eighth aspect of the present invention, a flight system includes a flight device and a reaction force mechanism according to the present invention. This allows, for example, freedom and naturalness of the pilot's physical movements during flight. That is, for example, it makes it easier for the pilot to change his / her posture during flight. Therefore, for example, it makes it easier to use the pilot's physical movements to give instructions regarding the operation of the flight device. Alternatively, it is possible to enjoy the other effects described above.

[0023] According to the above aspects of the present invention, it is possible to provide a reaction force mechanism and a flight system that allow the pilot to ensure freedom and naturalness of body movement during flight.

[0025] A flight system and reaction force mechanism 1 according to one embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1 , the flight system according to this embodiment comprises a flight device F and a reaction force mechanism 1. The flight device F is worn by a human pilot P, enabling the pilot P to fly. In this embodiment, the flight device F is worn on the upper body of the pilot P. In other words, the flight device F in this embodiment causes the pilot P's body from the waist down (particularly the legs L) to be suspended in mid-air during flight.

[0026] In the flight system according to this embodiment, the pilot P wears the reaction force mechanism 1, which allows the pilot P to operate the flight device F using the force of his or her legs, utilizing the reaction force received from the reaction force mechanism 1. In other words, the reaction force mechanism 1 is preferably connected to the flight device F when in use. The reaction force mechanism 1 is also preferably equipped with a bending sensor (not shown) that can detect, for example, the state of the pilot P's legs L, i.e., the bending angle of the pilot P's legs L. This preferably allows the state of the pilot P's legs L to be processed as information related to the operation of the flight device F.

[0027] Any known flying device may be suitably used as the flying device F. That is, for example, the flying device F may be a jet pack (Jet pack (registered trademark)) by Jetpack Aviation. Alternatively, the flying device F may be a jet suit (Jet Suit) by Gravity Industries. Alternatively, any other flying device may be used as the flying device F. The flying device F may fly by being appropriately operated by the pilot P, or may fly by automatic control. In this embodiment, the flying device F is attached via a buckle BC to a full harness H worn by the pilot P, as shown in FIGS. 10 to 12.

[0028] The reaction force mechanism 1 is attached to a pilot P wearing a flight device F. The reaction force mechanism 1 enables the pilot P to apply force to brace his legs while flying the flight device F. In this way, the reaction force mechanism 1 has the function of ensuring freedom and naturalness of body movement for the pilot P while flying.

[0029] (Outline of Reaction Mechanism) As shown in Fig. 1 , the reaction mechanism 1 includes a first section 10, a second section 20, and a third section 30. The first section 10 is attached to a part of the leg L of the operator P. The second section 20 is attached to the upper body or waist of the operator P. The third section 30 connects the first section 10 and the second section 20. For example, when the operator P, to which the first section 10 and the second section 20 are attached, stretches the leg L, the third section 30 is pulled by the first section 10 and the second section 20, generating tension.

[0030] With each of the above configurations, when the pilot P, to which the reaction force mechanism 1 is attached, extends his / her leg L, tension is generated in the third section 30. This tension allows the pilot P to receive a reaction force on his / her leg L via the first section 10. Therefore, even when the pilot P's feet Ft are not in contact with the ground during flight using the flight system, the pilot P can brace his / her feet Ft as if standing on the ground. This makes it easier for the pilot P to stabilize his / her posture during flight, for example. Alternatively, it makes it easier for the pilot P to change his / her posture during flight. The first section 10, the second section 20, and the third section 30 will be described in detail below.

[0031] (Details of First Part) The first part 10 is attached to a portion of the leg L of the operator P. One end of the third part 30 is connected to the first part 10. The first part 10 is attached, for example, by wrapping it around a portion of the leg L of the operator P. That is, the first part 10 is, for example, a strip-shaped member made of cloth or rubber. The first part 10 may also be attached, for example, by hooking it onto a portion of the leg L of the operator P. That is, the first part 10 may be formed, for example, of a wire 10W or a plate 10B made of metal or resin. The first part 10 is not limited to the above, and any other material may be used for the first part 10 as long as it is strong enough to withstand the force of the leg of the operator P. Below, several examples of locations where the first part 10 is fixed to the operator P will be described.

[0032] (First Example of First Part) As a first example, the first part 10 is fixed to, for example, the sole of the foot Ft of the operator P. Specifically, for example, as shown in FIG. 2 , the band-shaped first part 10 is fixed by being wrapped around the tip of the operator P's foot Ft. At this time, for example, the toes may be passed through the first part 10 formed into a ring shape using a band-shaped material. Alternatively, the first part 10 formed with hook-and-loop fasteners (not shown) on both ends of the band may be wrapped around the foot Ft, and the hook-and-loop fasteners may be attached to each other. Alternatively, as shown in FIG. 3 , the first part 10 may be formed by a plate 10B, a wire 10W, or the like, and the operator P's foot Ft may be hooked onto the first part 10. In this case, for example, as shown in FIG. 3 , the portion that contacts the sole of the operator P's foot Ft may be formed by the plate 10B, and the portion connecting the plate 10B and the third part 30 may be formed by the wire 10W. In this case, it is preferable that the board 10B is rectangular, for example, with its longitudinal direction aligned with the width direction of the foot Ft. The first section 10 formed as described above is preferably arranged to contact the sole of the operator P's foot Ft, particularly the area around the arch, as shown in FIG. 2 or 3. This makes it preferable that the operator P can easily move his / her ankle when the first section 10 is attached. Alternatively, the first section 10 may be arranged to contact the sole of the operator P's foot Ft, particularly the area around the toes, for example. This may make it easier for the operator P to step on the first section 10 using the force of his / her ankle.

[0033] (Second Example of First Part) As a second example, the first part 10 is fixed to, for example, the knee K of the operator P. Specifically, for example, as shown in FIG. 4 , the first part 10 formed in the shape of a knee support is fixed by being wrapped around the knee K of the operator P. In this case, a hole 10H may be formed in the first part 10 to expose the kneecap, thereby making it easier to bend and straighten the knee. In this case, for example, the leg L may be passed through the first part 10 formed in a tubular shape using a strip-shaped material. Alternatively, the first part 10 formed in a strip-like shape with hook-and-loop fasteners (not shown) on both ends may be wrapped around the foot Ft, and the hook-and-loop fasteners may be attached to each other. Furthermore, as shown in FIG. 5 , the first part 10 formed in a hook shape may be fixed to the knee K of the operator P by being hooked onto it. In this case, it is preferable that a metal or cloth hook holder 10F be provided in a portion of the operator P's clothing that is located at the knee K. 6, the first part 10, which is a belt, may be fastened by being hooked around the knee K of the operator P. In this case, it is preferable that a metal or cloth belt hook 10BF is provided on the part of the operator P's clothing that will be located at the knee K. Also, as shown in FIG. 7, the first part 10, which is a buckle, may be fastened by being assembled at the operator P's knee K. In this case, it is preferable that one side 10BC of the buckle is provided in advance on the part of the operator P's clothing that will be located at the knee K. Note that the first part 10 may be fastened to the operator P's calf, shin, or ankle using the structures shown in FIGS. 5 to 7.

[0034] (Details of the Second Part) The second part 20 is attached to the upper body or waist of the operator P. The other end of the third part 30 is connected to the second part 20. The second part 20 is, for example, formed in a corset shape and attached by wrapping around the operator P's waist or the like. That is, the second part 20 is, for example, a belt-like member made of cloth or rubber. The second part 20 may be attached by hooking onto any part of the operator P's upper body. That is, the second part 20 may be formed of, for example, a wire 10W or a plate 10B made of metal or resin. The second part 20 is not limited to the above, and any other material may be used for the second part 20 as long as it is strong enough to withstand the force of the operator P's legs. Below, several examples of locations where the second part 20 is fixed to the operator P will be described.

[0035] (First Example of Second Part) As a first example, the second part 20 is fastened to the shoulder of the rider P. Specifically, for example, as shown in FIG. 8 , the second part 20 is shaped like a bib vest and is fastened by being worn by the rider P. At this time, the third part 30 is connected to the shoulder of the rider P wearing the second part 20. In this embodiment, fastening the second part 20 to the shoulder of the rider P includes fastening the other end of the third part 30 to the shoulder of the rider P in this manner. Note that, as with the first part 10 described in FIGS. 5 to 7 , a hook, belt, or buckle may be used for the second part 20. At this time, it is preferable that a hook hook 10F, a belt hook 10BF, or one side of a buckle 10BC be provided on the shoulder of the rider P's clothing.

[0036] (Second Example of Second Part) As a second example, the second part 20 is fixed to the waist of the operator P. Specifically, for example, as shown in FIG. 9 , the second part 20 formed in a corset shape is wrapped around the waist of the operator P and fixed. In this case, for example, the body may be passed through the second part 20 formed in a tubular shape using a belt-like material. Alternatively, the second part 20 formed in a belt-like shape with hook-and-loop fasteners (not shown) on both ends may be wrapped around the waist, and the hook-and-loop fasteners may be attached to each other. Note that, as with the first part 10 described in FIGS. 5 to 7 , a hook, belt, or buckle may be used for the second part 20. In this case, it is preferable that a hook hook 10F, a belt hook 10BF, or one side of a buckle 10BC be provided on the waist portion of the operator P's clothing.

[0037] (Third Example of Second Part) As a third example, the second part 20 is fixed to the flight device F. Specifically, as shown in Fig. 10 , the second part 20 formed in a hook shape is fixed by hooking it onto the flight device F worn by the pilot P. Note that Fig. 10 only shows the framework of the flight device F in a schematic manner, and does not show other components such as the thrust mechanism. Note that instead of a hook, the second part 20 formed in a bracket shape may be fixed to the flight device F worn by the pilot P by bolting.

[0038] (Fourth Example of Second Part) As a fourth example, the second part 20 is fixed to, for example, a full harness H worn by the pilot P. Any known full harness H may be suitably used as the full harness H. Here, the pilot P may wear the flight device F via the full harness H. The second part 20 according to the fourth example is suitably used when the pilot P wears the full harness H. Specifically, as shown in FIG. 11 , the second part 20 is fixed to the waist of the full harness H. Alternatively, as shown in FIG. 12 , the second part 20 may be fixed to the shoulders of the full harness H. Here, when the pilot P wears the flight device F via the full harness H, the weight of the pilot P is applied to the base of the legs L of the pilot P via the full harness H. This causes pressure to be applied to the base of the legs L of the pilot P. When the second part 20 is fixed to the full harness H, the rider P can apply force to the first part 10 by bracing his / her legs, so that the weight of the rider P applied to the base of the rider P's legs L is applied to the first part 10 of the reaction force mechanism 1. This may prevent the base of the rider P's legs L from being compressed. The second part 20 in the fourth example may be formed by a hook, a belt, or a buckle, as in the first part 10 described with reference to FIGS. 5 to 7 . Alternatively, the other end of the third part 30 may be sewn to the full harness H as the second part 20. In this case, the second part 20 may be a connection between the third part 30 and the full harness H.

[0039] (Details of Part 3) The third part 30 connects the first part 10 and the second part 20. For example, when the operator P, to which the first part 10 and the second part 20 are attached, stretches his / her leg L, the third part 30 is pulled by the first part 10 and the second part 20, generating tension. This allows the operator P, to whom the reaction force mechanism 1 is attached, to receive a reaction force on his / her leg L via the first part 10, as described above. The third part 30 is, for example, a strip-shaped member made of cloth or rubber. This allows the third part 30 to more easily follow the movement of the operator P's leg L. This makes it easier to ensure the operator P's freedom of movement of the leg L. The third part 30 may be, for example, a plate-shaped member. This makes it easier to reliably generate a reaction force when the operator P stretches his / her leg L, for example. Furthermore, for example, if the third section 30 connecting the first section 10 and the second section 20 is a plate-shaped member, it is possible to more easily stably support the legs L of the pilot P during flight. That is, for example, when the pilot P is flying with his / her body aligned horizontally, it is possible for the pilot P to easily maintain the legs L in an extended state without exerting force on his / her legs. This makes it easier to stabilize the posture of the pilot P. Also, for example, it is possible to more easily reinforce the legs L of the pilot P. That is, for example, when the pilot P crashes to the ground, it is possible to prevent the pilot P from suffering injuries such as fractures due to the reaction force mechanism 1 receiving the impact of the crash. Not limited to the above, any other material may be used for the third section 30 as long as it is strong enough to withstand the force of the pilot P's legs.

[0040] As described above, the reaction force mechanism 1 according to this embodiment is attached to a pilot P wearing a flight device F. The reaction force mechanism 1 also includes a first section 10 attached to a portion of the pilot P's leg L, a second section 20 attached to the pilot P's upper body or waist, and a third section 30 connecting the first section 10 and the second section 20. As a result, when the pilot P to which the reaction force mechanism 1 is attached extends his leg L, tension is generated in the third section 30. This tension allows the pilot P to receive a reaction force from the first section 10 to his leg L. As a result, for example, even when the pilot P is flying using the flight device F and the pilot P's leg L is suspended in mid-air, i.e., the pilot P's foot Ft is not in contact with the ground, by extending the leg L, the pilot P can receive a force similar to the reaction force received from the ground when the pilot P is standing on the ground. Therefore, even when the feet Ft of the pilot P are not in contact with the ground, the pilot P can apply force to his / her legs by bracing himself / herself using the reaction force mechanism 1. This ensures freedom and naturalness of the pilot P's physical movements while the pilot P is flying. That is, for example, it is possible to make it easier for the pilot P to stabilize his / her posture while flying. Alternatively, it is possible to make it easier for the pilot P to change his / her posture while flying. Furthermore, by attaching such a reaction force mechanism 1 to the pilot P, it is possible to make it easier to use the pilot P's physical movements to give instructions regarding the operation of the flying device F.

[0041] Furthermore, the first section 10 is fixed to the soles of the feet Ft of the pilot P. This allows the pilot P to apply force to his legs as if bracing himself while flying, with the same sensation as when he is standing on the ground. This makes it easier to ensure greater freedom and naturalness in the pilot P's physical movements.

[0042] Furthermore, the first section 10 is fixed to the knee K of the pilot P. This reduces the number of devices attached to the part of the pilot P below the knee K. Therefore, for example, when the pilot P lands during flight, the pilot P can easily use the soles of his / her feet Ft freely.

[0043] Furthermore, the second section 20 is fixed to the shoulders of the pilot P. As a result, the reaction force caused by the pilot P extending his legs L is applied to the shoulders of the pilot P via the second section 20. This makes it possible to assist the back muscles, for example, with the force of the pilot P's legs. Therefore, for example, when the pilot P has relatively low muscle strength, it is possible to more easily assist the body movement of the pilot P during flight.

[0044] Furthermore, the second part 20 is fixed to the waist of the pilot P. This makes it possible to reduce, for example, the size of the reaction force mechanism 1. Therefore, it is possible to reduce, for example, the weight of the reaction force mechanism 1. Furthermore, it is possible to make it easier for the pilot P to move his / her body while walking on the ground or flying.

[0045] The second part 20 is also fixed to the flight device F. This allows the pilot P to apply a pulling force to the flight device F, for example, by extending the legs L. The force applied by the pilot P in this way can be used, for example, to control the flight device F. That is, for example, the thrust of the flight device F can be changed depending on the magnitude of the force with which the pilot P pulls the flight device F via the reaction force mechanism 1. Also, for example, the pilot P can change the attitude of the flight device F by changing its attitude using the reaction force mechanism 1. In this way, by allowing the pilot P to control the flight device F using the legs L, the pilot P can use his hands freely during flight. Therefore, the pilot P can perform some kind of work while remaining in the air using the flight device F.

[0046] Here, the pilot P may wear the flight device F via a full harness H. At this time, the pilot P is suspended in mid-air by the full harness H during flight. The pilot P's weight is then applied to the bases of the pilot P's legs L via the full harness H. This may compress the bases of the pilot P's legs L, causing the pilot P to feel pain. Furthermore, if the suspended state continues for a long period of time, congestion may occur at the bases of the pilot P's legs L. Therefore, the second part 20 of the reaction force mechanism 1 is attached to the full harness H worn by the pilot P. In this way, when the pilot P, to which the reaction force mechanism 1 is attached, extends his legs L, the weight of the pilot P applied to the bases of the pilot P's legs L can be applied to the first part 10 of the reaction force mechanism 1. This prevents the bases of the pilot P's legs L from being compressed. This prevents the pilot P from feeling pain and prevents congestion at the bases of the pilot P's legs L. Furthermore, by attaching such a reaction force mechanism 1 to the pilot P, it is possible to reduce the physical burden on the pilot P and contribute to extending the time the pilot P can fly. Furthermore, by having the pilot P wear the flight device F via a full harness H, it is possible to make it easier for the pilot P to put on and take off the flight device F.

[0047] Furthermore, the flight system according to this embodiment includes a flight device F and a reaction force mechanism 1 according to one embodiment of the present invention. This ensures, for example, freedom and naturalness of the body movements of the pilot P during flight. That is, for example, it makes it easier for the pilot P to change his / her posture during flight. Therefore, for example, it makes it easier to use the body movements of the pilot P to give instructions regarding the operation of the flight device F. Alternatively, it is possible to enjoy the other effects described above.

[0048] The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, the reaction force mechanism 1 according to the present embodiment may be used by someone other than the pilot P of the flight device F. For example, the reaction force mechanism 1 according to the present embodiment may be used by a person working at height, a stuntman, or the like.

[0049] In addition, within the scope of the spirit of the present invention, the components in the above-described embodiments may be replaced with well-known components as appropriate, and the above-described modifications may be combined as appropriate.

[0050] The above aspects of the present invention provide a reaction force mechanism and a flight system that ensures freedom and naturalness of body movement for the pilot during flight, and thus have great industrial applicability.
