Description

Safety device and flying vehicle equipped with safety device

[0001] The present invention relates to a safety device and an aircraft equipped with the safety device.

[0002] In recent years, advances in autonomous control and flight control technologies have accelerated the industrial use of drones, or other flying objects equipped with multiple rotors. Drones fly by simultaneously and balancedly rotating multiple rotors, for example. Drones ascend and descend by increasing or decreasing the rotor speed, and move forward or backward by tilting the aircraft through an increase or decrease in the rotor speed. These flying objects are not only used for disaster relief, cargo transportation, and landscape photography, but are also expected to carry people on board, and their use is expected to expand globally in the future.

[0003] On the other hand, the risk of aircraft falling accidents such as those mentioned above is seen as a danger, hindering the widespread use of aircraft. In order to reduce the risk of such falling accidents, safety devices such as parachutes for aircraft are being commercialized.

[0004] For example, Patent Document 1 discloses a gimbal vibration damper for an unmanned aerial vehicle that includes an upper vibration damping sheet, a lower vibration damping sheet, and a vibration damping component.

[0005] US Patent Application Publication No. 2018 / 0135723

[0006] Incidentally, it is desirable to suppress vibrations from being applied to a device for operating an actuator with a power source that is mounted on a safety device or an aircraft (such as a device that includes a control unit with a CPU, ROM, RAM, etc. to control the actuator, etc.).

[0007] Therefore, an object of the present invention is to provide a safety device or flying vehicle that can suppress vibrations from being applied to a device for operating an actuator having a power source.

[0008] (1) A safety device according to the present invention is a safety device for an aircraft, comprising: a container having a lid; a projectile contained in the container; a sliding member that slides to one side to push the lid from the inside and remove the lid; an actuator having a power source that generates a driving force to slide the sliding member to one side; a vibration-damping member that absorbs vibrations; and a positioning member that is attached to the container or the aircraft via the vibration-damping member and on which a device for operating the power source can be positioned.

[0009] (2) In the safety device of (1) above, it is preferable that the power source is located on the other side of the sliding member, and the positioning member is located on the other side of the container in a direction intersecting the sliding direction of the sliding member relative to the power source, and is attached to the container via the vibration-damping member.

[0010] (3) In the safety device of (1) above, it is preferable that the container is located on one side of the aircraft, the power source is located on the other side of the sliding member, and the positioning member is located on one side of the aircraft, on the other side of the container, and in a direction intersecting the sliding direction of the sliding member relative to the power source, and is attached to the aircraft via the vibration-damping member.

[0011] (4) In the safety device of (1) above, it is preferable that the power source is located on the other side of the sliding member, and the positioning member is located inside the container and in a direction intersecting the sliding direction of the sliding member relative to the power source, and is attached to the container via the vibration-damping member.

[0012] (5) In the safety devices of (1) to (4) above, the vibration-isolating member is preferably a vibration-isolating spring, a vibration-isolating rubber, a vibration-isolating damper, or a vibration-isolating pad.

[0013] (6) The flying body according to the present invention is characterized by comprising an airframe, any one of the safety devices (1) to (4) above connected to the airframe, and a device for operating the power source arranged on the arrangement member.

[0014] According to the present invention, it is possible to provide a safety device that can suppress vibrations from being applied to a device for operating an actuator having a power source, and an aircraft equipped with the safety device.

[0016] First Embodiment A safety device and an aircraft according to a first embodiment of the present invention will be described below with reference to FIGS. 1 and 2. FIG.

[0017] As shown in FIG. 1 , the safety device 100 includes a container 10, a projectile 20, an actuator 30, a plurality of collars 40, a plurality of bolts 50, a harness 60, a positioning member 70, and a plurality of vibration-damping members 80.

[0018] The container 10 contains the projectile 20. The container 10 has a main body 11 and a lid 12. The container 10 is located on one side of the flying vehicle 1 (the side indicated by the arrow X in Figure 1, etc.; the same applies below). Specifically, the main body 11 and the lid 12 are located on one side of the fuselage 2 of the flying vehicle 1. The one side is the side on which the piston member 31 slides due to the driving force generated by the gas generator 38.

[0019] The main body 11 has a bottom that is open on one side. The main body 11 has a hole 13 and a plurality of holes 14. The hole 13 is formed in the center of the bottom of the main body 11 and penetrates the bottom of the main body 11 in the sliding direction of the piston member 31. Note that, hereinafter, the sliding direction of the piston member 31 may be simply referred to as the sliding direction. The actuator 30 is inserted into the hole 13. The hole 14 is formed outward from the center of the bottom of the main body 11 and penetrates the bottom of the main body 11 in the sliding direction. A bolt 50 is inserted into the hole 14 to secure the container 10 and the actuator 30.

[0020] The lid portion 12 has a bottom and is open on the other side (the side indicated by arrow Y in Figure 1, etc.; the same applies below). The other side is the side opposite to the side along which the piston member 31 slides due to the driving force generated by the gas generator 38. The opening of the lid portion 12 is formed to fit into the opening of the main body portion 11. The lid portion 12 is attached to the main body portion 11 by fitting the opening of the lid portion 12 into the opening of the main body portion 11. The lid portion 12 has a tubular portion 15. The tubular portion 15 is formed in the center of the ceiling of the lid portion 12 and protrudes from the ceiling of the lid portion 12 to the other side. The tubular portion 15 is cylindrical and has a bottom and is open on the other side. An actuator 30 is disposed inside the tubular portion 15.

[0021] The projectile 20 is contained in the container 10. The projectile 20 is disposed between the cylindrical portion 15 and the side of the container 10. The projectile 20 is ejected from the container 10 when the lid 12 is removed. For example, if the lid 12 is removed from the main body 11 while the flying object 1 connected to the safety device 100 is falling, the projectile 20 becomes exposed to the outside and is ejected from the main body 11 by wind pressure or the like, or is ejected by being pulled out of the main body 11 by a string-like connecting member (not shown) connected to the lid 12. Note that a support member (a member having an overall shape similar to a hat) extending from the piston member 31 and supporting the projectile 20 may be provided, and the piston member 31 may be slid to one side to remove the lid 12 from the main body 11 and move the support member to one side, thereby ejecting the projectile 20 supported by the support member from the main body 11. In this embodiment, the projectile 20 is a parachute or a paraglider.

[0022] The actuator 30 includes a piston member 31 , a tubular member 32 , a holding member 33 , a seal member 34 , a cylinder 35 , a seal member 36 , a base 37 , and a gas generator 38 .

[0023] A portion of the actuator 30 is located outside the container 10 on the other side. Specifically, a portion of the actuator 30 is located outside the other end of the container 10 on the other side. More specifically, a portion of the actuator 30 is located outside the other side of the bottom of the main body 11. In this embodiment, a portion of the piston member 31, a portion of the cylinder 35, the base 37, and the gas generator 38 are located outside the container 10 on the other side.

[0024] Another part of the actuator 30 is located inside the container 10 and is housed in the container 10. In this embodiment, another part of the piston member 31, the tubular member 32, the holding member 33, the seal member 34, another part of the cylinder 35, and the seal member 36 are located inside the container 10 and are housed in the container 10.

[0025] The actuator 30 is disposed offset to the other side relative to the container 10. As a result, it becomes easier to adjust in advance the thickness of the portion of the container 10 that comes into contact with the piston member 31 during operation (for example, the thickness can be adjusted to match the output of the actuator), making it easier to adjust the strength of the container 10. In addition, it becomes easier to reduce the dimension of the container 10 in the sliding direction, improving the workability when storing the projectile 20.

[0026] The piston member 31 is an example of a sliding member that slides to one side to push the lid portion 12 from the inside and remove the lid portion 12. The lid portion 12 is located on one side of the piston member 31, and as the piston member 31 slides to one side, the piston member 31 comes into contact with the lid portion 12 and pushes the lid portion 12 to one side, and by pushing the lid portion 12 to one side, the lid portion 12 is removed from the main body portion 11. The piston member 31 is pushed up to one side by a driving force generated by the gas generator 38 and slides to one side relative to the cylinder 35. The piston member 31 extends in the sliding direction. The piston member 31 has a main body portion 31a, a rod-shaped portion 31b, a hole portion 31c, and a groove portion 31d.

[0027] The main body portion 31a has an outer diameter substantially equal to the inner diameter of the cylinder 35. The rod-shaped portion 31b is connected to the main body portion 31a, extends from one end of the main body portion 31a to one side, and has a smaller diameter than the main body portion 31a. The hole portion 31c is provided inside the main body portion 31a and the rod-shaped portion 31b. The hole portion 31c is formed along the central axis of the piston member 31 from the other end of the main body portion 31a to partway along the rod-shaped portion 31b. This makes the piston member 31 lighter than if the hole portion 31c were not formed. The groove portion 31d is provided on the outer peripheral surface of the main body portion 31a along the circumferential direction of the main body portion 31a.

[0028] The tubular member 32 is fitted or loosely fitted into the main body 31a at the other end of the rod-shaped portion 31b while contacting the main body 31a. A gap may be present between the inner peripheral surface of the tubular member 32 and the outer peripheral surface of the rod-shaped portion 31b, as long as the gap does not interfere with plastic deformation due to substantially uniform compression when the retaining member 33 and the stopper portion 35b of the cylinder 35 collide. The tubular member 32 is made of a material that undergoes plastic deformation and has a lower tensile strength than the piston member 31 (e.g., metals such as iron, aluminum, brass, copper, etc., alloys such as stainless steel, resins, etc.) (e.g., metals such as aluminum and brass, alloys such as stainless steel, resins such as monomer cast nylon, polyamide synthetic resins such as nylon 6, nylon 6,6, nylon 4,6, etc.). The tubular member 32 and the inner peripheral surface of the cylinder 35 are spaced apart by a predetermined distance or more (for example, a distance at which the tubular member 32, which has been plastically deformed by substantially uniform compression when the holding member 33 collides with the stopper portion 35b of the cylinder 35, does not come into contact with the inner peripheral surface of the cylinder 35) so that the tubular member 32 does not come into contact with the inner peripheral surface of the cylinder 35. As a result, even if the holding member 33 collides with the stopper portion 35b of the cylinder 35 and is plastically deformed, the tubular member 32 deforms without being hindered by the inner peripheral surface of the cylinder 35, and the impact on the piston member 31 is sufficiently absorbed.

[0029] The holding member 33 holds the tubular member 32 at the other end of the rod-shaped portion 31 b in contact with the main body portion 31 a. The holding member 33 may be an elastic member such as rubber, or may be made of the same material as the tubular member 32, and may be ring-shaped or clip-shaped.

[0030] The seal member 34 is provided in the groove 31d along the circumferential direction of the main body 31a. The seal member 34 is in contact with the groove 31d and the inner circumferential surface of the cylinder 35. The seal member 34 is an O-ring or the like.

[0031] The cylinder 35 accommodates the piston member 31 and slidably supports the piston member 31. The cylinder 35 extends in the sliding direction. The cylinder 35 has a hole 35a, a stopper 35b, and a groove 35c.

[0032] The hole 35a is a hole through which the piston member 31 protrudes toward one side relative to the cylinder 35 during operation. The hole 35a penetrates one end of the cylinder 35 in the sliding direction. The piston member 31 is inserted into the hole 35a. The stopper portion 35b is formed inside the one end of the cylinder 35. The stopper portion 35b is cylindrical and disposed so as to surround a portion of the rod-shaped portion 31b of the piston member 31. The stopper portion 35b limits the sliding range of the piston member 31 toward one side. When the piston member 31 slides toward one side due to the driving force generated by the gas generator 38, the holding member 33 collides with the stopper portion 35b, thereby limiting the sliding toward one side. The groove portion 35c is provided on the inner peripheral surface of the stopper portion 35b along the circumferential direction of the stopper portion 35b.

[0033] The seal member 36 is provided in the groove portion 35c along the circumferential direction of the stopper portion 35b. The seal member 36 is in contact with the groove portion 35c and the outer peripheral surface of the piston member 31. The seal member 36 is an O-ring or the like.

[0034] The other end of the cylinder 35 is fixed by crimping to the base 37. The base 37 is fixed to the fuselage 2 of the aircraft 1 by fastening a bolt (not shown) into a hole (not shown, with an internal thread) provided in a flange 37b of the base 37. The base 37 is a squib holder. The base 37 has a substantially cylindrical member 37a, a flange 37b, and an insertion opening 37c.

[0035] The substantially cylindrical member 37a holds the gas generator 38 on the cylinder 35 side. The flange portion 37b is provided on the side of the substantially cylindrical member 37a opposite to the cylinder 35 side. The flange portion 37b has a plurality of holes 37d. The holes 37d are used to attach the base 37 to the container 10. An internal thread is cut on the inner circumferential surface of the hole 37d, and a bolt 50 inserted from the inside of the container 10 is screwed into the hole 37d. The insertion port 37c is used to insert an electrical connector 61 into the electrode 38b of the gas generator 38.

[0036] The gas generator 38 is located on the other side of the piston member 31 and is an example of a power source that generates a driving force to slide the piston member 31 to one side. The gas generator 38 is inserted into the opening on the other side of the cylinder 35 and is disposed on the other side of the piston member 31. The gas generator 38 may be an igniter alone, or a gas generator equipped with an igniter and a gas generant. Alternatively, a hybrid or stored-type gas generator may be used in which a gunpowder-type igniter ruptures the seal of a small gas cylinder, releasing the gas inside. In this case, the pressurized gas in the gas cylinder may be a non-flammable gas such as argon, helium, nitrogen, or carbon dioxide, or a mixture thereof. Furthermore, the gas generator may be equipped with a heating element made of a gas generant composition or a thermite composition to reliably propel the piston when the pressurized gas is released. The gas generator 38 is, for example, a micro gas generator. The gas generator 38 has a cup body 38a and multiple electrodes 38b.

[0037] An igniter is disposed inside the cup body 38a. Also, for example, a gas generating agent, a gas cylinder, and / or a heating element are appropriately disposed inside the cup body 38a. The electrode 38b is electrically connected to the igniter disposed inside the cup body 38a.

[0038] The collar 40 is a member for offsetting the actuator 30 to the other side relative to the container 10. The collar 40 is disposed between the bottom of the main body 11 of the container 10 and the flange 37b of the base 37. The collar 40 has a cylindrical shape extending in the sliding direction, and the internal space of the collar 40 communicates with the hole 14 and the hole 37d.

[0039] The bolt 50 is a member for fixing the container 10 and the actuator 30 together. The bolt 50 is inserted through the hole 14 and the collar 40 from the inside of the container 10, and is threaded into the hole 37d. By tightening the bolt 50, the container 10 and the actuator 30 are fixed together.

[0040] The harness 60 is a member for electrically connecting the gas generator 38 and the trigger device 90. The harness 60 has a connector 61.

[0041] The connector 61 is located on the other side of the gas generator 38 and is connected to the electrode 38b. The harness 60 has a connector (not shown) connected to the trigger device 90 and wiring (not shown) connected to the connector 61. As a result, a signal from the trigger device 90 is supplied to the gas generator 38, causing the gas generator 38 to operate.

[0042] The arrangement member 70 is a member on which a device for activating the gas generator 38 can be placed. In the present embodiment, the arrangement member 70 is a member for placing a trigger device 90 for activating the gas generator 38. Note that not only the trigger device 90 but also a battery for storing power to be supplied to the trigger device 90 may be placed in the arrangement member 70, or an accessory member such as wiring for connecting the trigger device 90 to the battery may be placed in the arrangement member 70. Furthermore, a buzzer device (sound source) and / or an LED (light source) that indicates the state of the trigger device 90 may be placed in the arrangement member 70. The arrangement member 70 has a main body portion 71 and a lid portion 72.

[0043] The main body 71 has a bottom and is open on one side. As described above, a portion of the actuator 30 is located on the other side of the container 10, and the main body 71 is arranged in a ring shape so as to surround the portion.

[0044] The lid portion 72 has a bottom that opens on the other side. As described above, a portion of the actuator 30 is located on the other side of the container 10, and the lid portion 72 is arranged in a ring shape to surround that portion. The opening of the lid portion 72 is formed to fit into the opening of the main body portion 71. The lid portion 72 is attached to the main body portion 71 by fitting the opening of the lid portion 72 into the opening of the main body portion 71.

[0045] The positioning member 70 is located on the other side of the container 10. Specifically, the main body 71 and the lid 72 are located on the other side of the main body 11 and the lid 12 of the container 10. The positioning member 70 is located on one side of the aircraft 1. Specifically, the main body 71 and the lid 72 are located on one side of the fuselage 2 of the aircraft 1. In this way, the positioning member 70 is located between the container 10 and the aircraft 1.

[0046] The arrangement member 70 is positioned offset relative to the gas generator 38 in a transverse direction intersecting the sliding direction, and is not positioned in the sliding direction, which is the direction from one side of the gas generator 38 to the other. In the present embodiment, the arrangement member 70 is disposed so as to be positioned in a direction perpendicular to the sliding direction relative to the gas generator 38. Specifically, the main body 71 is positioned in a direction perpendicular to the sliding direction relative to the electrode 38b. The lid 72 is positioned in a direction perpendicular to the sliding direction relative to the cup body 38a. Note that, hereinafter, the transverse direction intersecting the sliding direction may be simply referred to as the transverse direction. Furthermore, the orthogonal direction perpendicular to the sliding direction may be simply referred to as the orthogonal direction.

[0047] As described above, a portion of the actuator 30 is located outside the container 10 on the other side, and the arrangement member 70 is located perpendicular to that portion. Specifically, the main body 71 is located perpendicular to the cylinder 35, the approximately cylindrical member 37a, the flange 37b, the insertion port 37c, and the electrode 38b, which are parts of the actuator 30. Furthermore, the lid 72 is located perpendicular to the cylinder 35, the approximately cylindrical member 37a, and the cup body 38a, which are parts of the actuator 30.

[0048] The positioning member 70 forms a space 73 for accommodating the trigger device 90. The space 73 is a space surrounded by the main body portion 71 and the lid portion 72. The trigger device 90 is disposed in the space 73 and accommodated in the positioning member 70. In this manner, in this embodiment, the positioning member 70 is a case for accommodating the trigger device 90.

[0049] The positioning member 70 is attached to the container 10 via a vibration-isolating member 80. Specifically, the positioning member 70 is attached to the main body 11 of the container 10 via the vibration-isolating member 80. The vibration-isolating member 80 will be described later. The positioning member 70 is not only arranged so as not to come into direct contact with the aircraft 1, the container 10, the actuator 30, the plurality of collars 40, etc. in the initial state, but also so as not to come into direct contact with the aircraft 1, the container 10, the actuator 30, the plurality of collars 40, etc. when the safety device 100 is activated or when the aircraft 1 is flying.

[0050] Since the components constituting the placement member 70 and the components constituting the container 10 are separate, manufacturability and assembly are improved, and the container can also be made to accommodate complex shapes that match the surface shape of the object to which it is attached (for example, the surface shape of an aircraft), thereby improving versatility and design.

[0051] The trigger device 90 includes, for example, a control unit (not shown) having a CPU, ROM, RAM, etc., and an abnormal state determination unit (not shown) that determines whether the aircraft 1 is in an abnormal state based on a signal received from a detection unit (not shown) that detects the state of the aircraft 1 (failure, loss of control, flight state (flight attitude, speed, angular velocity, altitude, attitude angle, etc.), distance to obstacles, position information, etc.). The trigger device 90 is configured to execute various programs (signal transmission program, signal reception program, etc.) using the CPU to automatically transmit command signals, activation signals, etc. to each component depending on the situation (for example, when the aircraft 1 is in an abnormal state (abnormal)), or to receive command signals, etc. from an external source via a communication unit (not shown) and transmit command signals, activation signals, etc. to each component. For example, when the aircraft 1 is in an abnormal state, the trigger device 90 has the function of transmitting an automatic activation signal to the actuator 30 by executing various programs using the CPU to the actuator 30, or transmitting an activation signal to the actuator 30 by executing various programs using the CPU to the actuator 30 when a trigger signal is received from a remote signal transmitter / receiver operated by the operator.

[0052] Examples of the detection unit include a signal receiving sensor, an acceleration sensor, a gyro sensor, a barometric pressure sensor, a GPS (Global Positioning System), a laser sensor, an ultrasonic sensor, an infrared sensor, a millimeter wave radar, a submillimeter wave radar, a speed sensor, a monocular or compound eye vision sensor, an energy amount sensor, and a wind direction detection sensor, and the detection unit includes at least one of these. Other examples of the detection unit may include a unit that detects that an emergency signal has been transmitted from an emergency signal transmitting device in response to an operation by an operator, a unit that detects a malfunction of equipment installed in the aircraft 1, etc.

[0053] Furthermore, the above-mentioned "abnormal state" refers to a case where the abnormal state determination unit determines that the aircraft 1 is in an abnormal state (such as malfunction, inoperability, or an abnormal fall) based on a signal from the above-mentioned detection unit provided in the aircraft 1 or the safety device 100. Specifically, the abnormal state determination unit determines that "signal loss from the control unit of the aircraft 1 for a certain period of time or reception of an abnormal signal from the control unit of the aircraft 1", "signal loss from the remote signal transmitter / receiver for a certain period of time or reception of an abnormal signal from the remote signal transmitter / receiver", "signal loss from the ground station for a certain period of time or reception of an abnormal signal from the ground station when there is communication with a ground station (including a relay station)", "position information of the aircraft 1 indicates that the aircraft 1 is approaching or entering a prohibited area or deviating from the planned route", "remaining amount of power supply (battery) or fuel of the aircraft 1 is below a specified value", "acceleration of the aircraft 1 is below a specified value or above a specified value", This occurs when it is determined that one or more of the following conditions have occurred: "The angular velocity of the aircraft 1 is equal to or greater than a specified value," "The attitude angle of the aircraft 1 is equal to or greater than a specified value (for example, tilted 45° or more from the horizontal)," "The aircraft 1 is approaching an obstacle that may cause damage to the aircraft 1 (detected by a laser sensor (such as LiDAR) or an infrared sensor, or by a vision sensor and image analysis)," "If the aircraft 1 is capable of carrying a person, an emergency situation has occurred for a person inside the aircraft 1 (detected by an emergency signal being transmitted from the emergency signal transmitter)," or "A fatal malfunction of equipment installed in the aircraft 1."

[0054] The vibration-damping member 80 absorbs vibrations. For example, the vibration-damping member 80 is expandable and absorbs vibrations by expanding and contracting. The vibration-damping member 80 is also shear-deformable and absorbs vibrations by shear deformation. Specifically, for example, the vibration-damping member 80 is expandable and contractable in the sliding direction and absorbs vibrations in the sliding direction. The vibration-damping member 80 is also shear-deformable in the perpendicular direction and absorbs vibrations in the perpendicular direction. The vibration-damping member 80 is located on the other side of the container 10 and on one side of the arrangement member 70, and is located between the container 10 and the arrangement member 70.

[0055] Here, the vibration-isolating member 80 is a vibration-isolating spring. For example, one end of the vibration-isolating member 80 is attached to a fixing member that is fixed to the main body 11 of the container 10 by screwing or the like, and the other end of the vibration-isolating member 80 is attached to a fixing member that is fixed to the lid 72 of the arrangement member 70 by screwing or the like. In this way, the arrangement member 70 is attached to the container 10 via the vibration-isolating member 80.

[0056] The vibration-isolating member 80 may be vibration-isolating rubber. When the vibration-isolating member 80 is vibration-isolating rubber, for example, one end of the vibration-isolating member 80 is attached to a fixing member that is fixed to the main body 11 of the container 10 by screwing or the like, and the other end of the vibration-isolating member 80 is attached to a fixing member that is fixed to the lid 72 of the arrangement member 70 by screwing or the like. In this way, the arrangement member 70 is attached to the container 10 via the vibration-isolating member 80.

[0057] Furthermore, the vibration-isolating member 80 may be a vibration-isolating damper. When the vibration-isolating member 80 is a vibration-isolating damper, for example, one end of the vibration-isolating member 80 is attached to the main body 11 of the container 10 by screwing or the like, and the other end of the vibration-isolating member 80 is attached to the lid 72 of the arrangement member 70 by screwing or the like. In this way, the arrangement member 70 is attached to the container 10 via the vibration-isolating member 80.

[0058] When vibrations of the flying vehicle 1 are transmitted to the container 10, the vibrations are absorbed by the vibration-damping member 80, and the vibrations can be prevented from being transmitted to the arrangement member 70. Furthermore, vibrations generated when the gas generator 38 generates a driving force are absorbed by the vibration-damping member 80, and the vibrations can be prevented from being transmitted to the arrangement member 70. As a result, vibrations can be prevented from being applied to the trigger device 90 and the like arranged on the arrangement member 70.

[0059] As shown in FIG. 2, the flying object 1 includes a body 2, a plurality of propulsion mechanisms 3, a plurality of legs 4, a safety device 100, and a trigger device 90 (see FIG. 1).

[0060] The propulsion mechanism 3 is coupled to the airframe 2 and propels the airframe 2. For example, the propulsion mechanism 3 is a propeller or the like. The legs 4 are provided on the lower part of the airframe 2. The safety device 100 is coupled to the airframe 2. As described above, for example, a bolt (not shown) inserted from inside the airframe 2 is threadedly engaged with a hole (not shown) in the flange portion 37b and tightened, thereby coupling the safety device 100 to the airframe 2. The trigger device 90 is disposed on the positioning member 70.

[0061] As described above, the safety device 100 in the first embodiment of the present invention is a safety device for an aircraft 1, and comprises a container 10 having a lid portion 12, a projectile 20 contained in the container 10, an actuator 30 having a piston member 31 that slides to one side to push the lid portion 12 from the inside and remove the lid portion 12, and a gas generator 38 that generates a driving force to slide the piston member 31 to one side, a vibration-damping member 80 that absorbs vibrations, and a positioning member 70 that is attached to the container 10 via the vibration-damping member 80 and on which a trigger device 90 for activating the gas generator 38 can be placed.

[0062] According to this, since the positioning member 70 is attached to the container 10 via the vibration-isolating member 80, vibrations of the container 10 are absorbed by the vibration-isolating member 80, and the vibrations can be prevented from being transmitted to the positioning member 70. Therefore, the application of vibrations to the trigger device 90 arranged on the positioning member 70 can be prevented.

[0063] Furthermore, in the safety device 100 according to the first embodiment of the present invention, the gas generator 38 is located on the other side of the piston member 31, and the positioning member 70 is located on the other side of the container 10 in a direction intersecting the sliding direction of the piston member 31 relative to the gas generator 38, and is attached to the container 10 via the vibration-damping member 80.

[0064] This can prevent vibrations that occur when the gas generator 38 generates a driving force from being transmitted to the arrangement member 70. Therefore, it is possible to further prevent vibrations from being applied to the trigger device 90 arranged on the arrangement member 70.

[0065] In the safety device 100 according to the first embodiment of the present invention, the vibration-isolating member 80 is a vibration-isolating spring, a vibration-isolating rubber, or a vibration-isolating damper.

[0066] According to this, vibrations can be easily absorbed by the vibration-isolating spring, vibration-isolating damper, or vibration-isolating rubber, so that the application of vibrations to the trigger device 90 arranged on the arrangement member 70 can be easily suppressed.

[0067] The aircraft 1 in the first embodiment of the present invention also includes the airframe 2, a safety device 100 coupled to the airframe 2, and a trigger device 90 arranged on the arrangement member 70.

[0068] This provides the same effects as the safety device 100 described above.

[0069] Second Embodiment A safety device according to a second embodiment of the present invention will be described below with reference to Fig. 3. In this embodiment, reference numerals having the same last two digits as those in the first embodiment are similar, and therefore their description may be omitted. Furthermore, parts that are not particularly described are similar to the safety device and flying vehicle of the first embodiment, and therefore their description may be omitted.

[0070] As shown in Figure 3, the safety device 200 of this embodiment differs from the safety device 100 of the first embodiment described above mainly in that it is equipped with a vibration-damping member 180 instead of the vibration-damping member 80 of the first embodiment described above.

[0071] Here, the vibration-isolating member 180 is a vibration-isolating pad. For example, one end face of the vibration-isolating member 180 is attached to the main body 111 of the container 110 with an adhesive or the like, and the other end face of the vibration-isolating member 180 is attached to the lid 172 of the arrangement member 170 with an adhesive or the like. In this way, the arrangement member 170 is attached to the container 110 via the vibration-isolating member 180. For example, the vibration-isolating pad is made of rubber, gel, urethane, or the like.

[0072] The flying body 101 differs from the flying body 1 according to the first embodiment above mainly in that it is equipped with a safety device 200 instead of the safety device 100. The positioning member 170 is not only arranged so as not to come into direct contact with the flying body 101, container 110, actuator 130, and multiple collars 140 in the initial state, but also so as not to come into direct contact with the flying body 101 when the safety device 200 is activated and when the flying body 101 is flying.

[0073] As described above, in the safety device 200 according to the second embodiment of the present invention, the vibration-isolating member 180 is a vibration-isolating pad.

[0074] According to this, vibrations can be easily absorbed by the vibration-proof pad, and therefore, vibrations can be easily prevented from being applied to the trigger device 190 arranged on the arrangement member 170.

[0075] Third Embodiment A safety device according to a third embodiment of the present invention will now be described with reference to Fig. 4. In this embodiment, reference numerals having the same last two digits as those in the first embodiment are similar, and therefore their descriptions may be omitted. Furthermore, parts that are not particularly described are similar to the safety device and flying vehicle of the first embodiment, and therefore their descriptions may be omitted.

[0076] As shown in Figure 4, the safety device 300 of this embodiment differs mainly from the safety device 100 of the first embodiment described above in that the positioning member 270 is attached to the aircraft 201 via a vibration-damping member 280.

[0077] The vibration-damping member 280 is located on the other side of the positioning member 270 and on one side of the aircraft 201, and is located between the positioning member 270 and the aircraft 201. Specifically, the vibration-damping member 280 is located on the other side of the positioning member 270 and on one side of the airframe 202, and is located between the positioning member 270 and the airframe 202. Note that the positioning member 270 is not only arranged so as not to come into direct contact with the aircraft 201, the container 210, the actuator 230, the plurality of collars 240, etc. in the initial state, but is also arranged so as not to come into direct contact with the aircraft 201, the container 210, the actuator 230, the plurality of collars 240, etc. when the safety device 300 is activated and when the aircraft 201 is flying.

[0078] Here, vibration-damping member 280 is a vibration-damping spring. For example, one end of vibration-damping member 280 is attached to a fixing member that is fixed to main body 271 of arrangement member 270 by screwing or the like, and the other end of vibration-damping member 280 is attached to a fixing member that is fixed to airframe 202 of aircraft 201 by screwing or the like. In this way, arrangement member 270 is attached to aircraft 201 via vibration-damping member 280.

[0079] It should be noted that vibration-isolating member 280 may be vibration-isolating rubber. When vibration-isolating member 280 is vibration-isolating rubber, for example, one end of vibration-isolating member 280 is attached to a fixing member that is fixed to main body 271 of arrangement member 270 by screwing or the like, and the other end of vibration-isolating member 280 is attached to a fixing member that is fixed to airframe 202 of aircraft 201 by screwing or the like. In this way, arrangement member 270 is attached to aircraft 201 via vibration-isolating member 280.

[0080] Furthermore, the vibration-isolating member 280 may be a vibration-isolating damper. When the vibration-isolating member 280 is a vibration-isolating damper, for example, one end of the vibration-isolating member 280 is attached to the main body 271 of the arrangement member 270 by screwing or the like, and the other end of the vibration-isolating member 280 is attached to the airframe 202 of the aircraft 201 by screwing or the like. In this way, the arrangement member 270 is attached to the aircraft 201 via the vibration-isolating member 280.

[0081] Vibrations of the flying object 201 are absorbed by the vibration-damping member 280, and transmission of the vibrations to the arrangement member 270 can be suppressed. Furthermore, if vibrations generated when the gas generator 238 generates a driving force are transmitted to the flying object 201, the vibrations are absorbed by the vibration-damping member 280, and transmission of the vibrations to the arrangement member 270 can be suppressed. As a result, vibrations can be suppressed from being applied to the trigger device 290 and the like arranged on the arrangement member 270.

[0082] The flying vehicle 201 differs from the flying vehicle 1 according to the first embodiment described above mainly in that it is equipped with a safety device 300 instead of the safety device 100 .

[0083] As described above, the safety device 300 in the third embodiment of the present invention is a safety device for an aircraft 201, and comprises a container 210 having a lid portion 212, a projectile 220 contained in the container 210, a piston member 231 that slides to one side to push the lid portion 212 from the inside and remove the lid portion 212, an actuator 230 having a gas generator 238 that generates a driving force to slide the piston member 231 to one side, a vibration-damping member 280 that absorbs vibrations, and a positioning member 270 that is attached to the aircraft 201 via the vibration-damping member 280 and on which a trigger device 290 for activating the gas generator 238 can be placed.

[0084] According to this, since the arrangement member 270 is attached to the flying object 201 via the vibration-isolating member 280, vibrations of the flying object 201 are absorbed by the vibration-isolating member 280, and transmission of the vibrations to the arrangement member 270 can be suppressed. Therefore, application of vibrations to the trigger device 290 arranged on the arrangement member 270 can be suppressed.

[0085] Furthermore, in the safety device 300 of the third embodiment of the present invention, the container 210 is located on one side of the aircraft 201, the gas generator 238 is located on the other side of the piston member 231, and the positioning member 270 is located on one side of the aircraft 201, on the other side of the container 210, and in a direction intersecting the sliding direction of the piston member 231 relative to the gas generator 238, and is attached to the aircraft 201 via the vibration-damping member 280.

[0086] This can prevent vibrations that occur when the gas generator 238 generates a driving force from being transmitted to the arrangement member 270. Therefore, it is possible to further prevent vibrations from being applied to the trigger device 290 arranged on the arrangement member 270.

[0087] In the safety device 300 according to the third embodiment of the present invention, the vibration-isolating member 280 is a vibration-isolating spring, a vibration-isolating rubber, or a vibration-isolating damper.

[0088] According to this, vibrations can be easily absorbed by the vibration-isolating spring, vibration-isolating damper, or vibration-isolating rubber, so that the application of vibrations to the trigger device 290 arranged on the arrangement member 270 can be easily suppressed.

[0089] Moreover, the flying object 201 in the third embodiment of the present invention includes an airframe 202 , a safety device 300 coupled to the airframe 202 , and a trigger device 290 arranged on the arrangement member 270 .

[0090] This provides the same effects as the safety device 300 described above.

[0091] <Fourth embodiment> A safety device according to a fourth embodiment of the present invention will be described below with reference to Fig. 5. In this embodiment, reference numerals having the same last two digits as those in the third embodiment are similar, and therefore their description may be omitted. Furthermore, parts that are not particularly described are similar to the safety device and flying vehicle of the third embodiment, and therefore their description may be omitted.

[0092] 5, the safety device 400 according to this embodiment differs from the safety device 300 according to the third embodiment in that it includes a vibration-isolating member 380 instead of the vibration-isolating member 280 of the third embodiment. The positioning member 370 is not only arranged so as not to come into direct contact with the flying vehicle 301, container 310, actuator 330, and multiple collars 340 in the initial state, but also so as not to come into direct contact with the flying vehicle 301 when the safety device 400 is activated or when the flying vehicle 301 is flying.

[0093] Here, vibration-isolating member 380 is a vibration-isolating pad. For example, one end face of vibration-isolating member 380 is attached to main body 371 of arrangement member 370 with an adhesive or the like, and the other end face of vibration-isolating member 380 is attached to airframe 302 of aircraft 301 with an adhesive or the like. In this way, arrangement member 370 is attached to aircraft 301 via vibration-isolating member 380. For example, the vibration-isolating pad is made of rubber, gel, urethane, or the like.

[0094] The flying vehicle 301 differs from the flying vehicle 201 according to the third embodiment mainly in that the flying vehicle 301 is provided with a safety device 400 instead of the safety device 300 .

[0095] As described above, in the safety device 400 according to the fourth embodiment of the present invention, the vibration-isolating member 380 is a vibration-isolating pad.

[0096] According to this, vibrations can be easily absorbed by the vibration-proof pad, and therefore, vibrations can be easily prevented from being applied to the trigger device 390 arranged on the arrangement member 370.

[0097] Fifth Embodiment A safety device according to a fifth embodiment of the present invention will be described below with reference to Fig. 6. In this embodiment, reference numerals having the same last two digits as those in the first embodiment are similar, and therefore their description may be omitted. Furthermore, parts that are not particularly described are similar to the safety device and flying vehicle of the first embodiment, and therefore their description may be omitted.

[0098] 6 , the safety device 500 according to this embodiment differs from the safety device 100 according to the first embodiment mainly in that the arrangement member 470 is located inside the container 410. The arrangement member 470 is not only arranged so as not to come into direct contact with the container 410, the actuator 430, etc. in the initial state, but also so as not to come into direct contact with them when the safety device 500 is activated or when the flying object 501 is flying. The arrangement member 470 may be in contact with the projectile 420, but a partition wall or the like may be provided between the arrangement member 470 and the projectile 420 to prevent the arrangement member 470 from coming into contact with the projectile 420.

[0099] The vibration-damping member 480 is located inside the container 410, on the other side of the positioning member 470 and on one side of the bottom of the main body 411 of the container 410, and is located between the positioning member 470 and the bottom of the main body 411 of the container 410.

[0100] Here, vibration-isolating member 480 is a vibration-isolating spring. For example, one end of vibration-isolating member 480 is attached to a fixing member that is fixed to main body 471 of arrangement member 470 by screwing or the like, and the other end of vibration-isolating member 480 is attached to a fixing member that is fixed to the bottom of main body 411 of container 410 by screwing or the like. In this way, arrangement member 470 is attached to container 410 via vibration-isolating member 480.

[0101] It should be noted that vibration-isolating member 480 may be vibration-isolating rubber. When vibration-isolating member 480 is vibration-isolating rubber, for example, one end of vibration-isolating member 480 is attached to a fixing member that is fixed to main body 471 of arrangement member 470 by screwing or the like, and the other end of vibration-isolating member 480 is attached to a fixing member that is fixed to the bottom of main body 411 of container 410 by screwing or the like. In this way, arrangement member 470 is attached to container 410 via vibration-isolating member 480.

[0102] Furthermore, vibration-isolating member 480 may be a vibration-isolating damper. When vibration-isolating member 480 is a vibration-isolating damper, for example, one end of vibration-isolating member 480 is attached to main body 471 of arrangement member 470 by screwing or the like, and the other end of vibration-isolating member 480 is attached to the bottom of main body 411 of container 410 by screwing or the like. In this way, arrangement member 470 is attached to container 410 via vibration-isolating member 480.

[0103] When vibrations of the flying object 401 are transmitted to the container 410, the vibrations are absorbed by the vibration-isolating member 480, and the vibrations can be prevented from being transmitted to the arrangement member 470. Furthermore, vibrations generated when the gas generator 438 generates a driving force are absorbed by the vibration-isolating member 480, and the vibrations can be prevented from being transmitted to the arrangement member 470. As a result, vibrations can be prevented from being applied to the trigger device 490 and the like arranged on the arrangement member 470.

[0104] The flying vehicle 401 differs from the flying vehicle 1 according to the first embodiment described above mainly in that it is equipped with a safety device 500 instead of the safety device 100 .

[0105] As described above, the safety device 500 in the fifth embodiment of the present invention is a safety device for an aircraft 401, and comprises a container 410 having a lid portion 412, a projectile 420 contained in the container 410, an actuator 430 having a piston member 431 that slides to one side to push the lid portion 412 from the inside and remove the lid portion 412, and a gas generator 438 that generates a driving force to slide the piston member 431 to one side, a vibration-damping member 480 that absorbs vibrations, and a positioning member 470 that is attached to the container 410 via the vibration-damping member 480 and on which a trigger device 490 for activating the gas generator 438 can be placed.

[0106] According to this, since the arrangement member 470 is attached to the container 410 via the vibration-isolating member 480, vibrations of the container 410 are absorbed by the vibration-isolating member 480, and it is possible to prevent the vibrations from being transmitted to the arrangement member 470. Therefore, it is possible to prevent vibrations from being applied to the trigger device 490 arranged on the arrangement member 470.

[0107] Furthermore, in the safety device 500 according to the fifth embodiment of the present invention, the gas generator 438 is located on the other side of the piston member 431, and the positioning member 470 is located inside the container 410 and in a direction intersecting the sliding direction of the piston member 431 relative to the gas generator 438, and is attached to the container 410 via the vibration-damping member 480.

[0108] This can prevent vibrations that occur when the gas generator 438 generates a driving force from being transmitted to the arrangement member 470. Therefore, it is possible to further prevent vibrations from being applied to the trigger device 490 that is arranged on the arrangement member 470. In addition, the safety device 500 can be made even more compact.

[0109] In the safety device 500 according to the fifth embodiment of the present invention, the vibration-isolating member 480 is a vibration-isolating spring, a vibration-isolating rubber, or a vibration-isolating damper.

[0110] According to this, vibrations can be easily absorbed by the vibration-isolating spring, vibration-isolating damper, or vibration-isolating rubber, so that the application of vibrations to the trigger device 490 arranged on the arrangement member 470 can be easily suppressed.

[0111] Furthermore, the flying object 401 in the fifth embodiment of the present invention includes a body 402 , a safety device 500 coupled to the body 402 , and a trigger device 490 arranged on the arrangement member 470 .

[0112] This provides the same effects as the safety device 500 described above.

[0113] Sixth Embodiment A safety device according to a sixth embodiment of the present invention will be described below with reference to Fig. 7. In this embodiment, reference numerals having the same last two digits as those in the fifth embodiment are similar, and therefore their description may be omitted. Furthermore, parts that are not particularly described are similar to the safety device and flying vehicle of the fifth embodiment, and therefore their description may be omitted.

[0114] 7 , the safety device 600 according to this embodiment differs from the safety device 500 according to the fifth embodiment mainly in that it includes a vibration-isolating member 580 instead of the vibration-isolating member 480 of the fifth embodiment. The positioning member 570 is not only arranged so as not to come into direct contact with the container 510, the actuator 530, etc. in the initial state, but also so as not to come into direct contact with them when the safety device 600 is activated or when the flying object 501 is flying. The positioning member 570 may be in contact with the projectile 520, but a partition wall or the like may be provided between the positioning member 570 and the projectile 520 to prevent the positioning member 570 from coming into contact with the projectile 520.

[0115] Here, vibration-isolating member 580 is a vibration-isolating pad. For example, one end face of vibration-isolating member 580 is attached to main body 571 of arrangement member 570 with an adhesive or the like, and the other end face of vibration-isolating member 580 is attached to the bottom of main body 511 of container 510 with an adhesive or the like. In this way, arrangement member 570 is attached to container 510 via vibration-isolating member 580. For example, the vibration-isolating pad is made of rubber, gel, urethane, or the like.

[0116] The flying vehicle 501 differs from the flying vehicle 401 according to the fifth embodiment described above mainly in that it is equipped with a safety device 600 instead of the safety device 500 .

[0117] As described above, in the safety device 600 according to the sixth embodiment of the present invention, the vibration-isolating member 580 is a vibration-isolating pad.

[0118] According to this, vibrations can be easily absorbed by the vibration-proof pad, and therefore, vibrations can be easily prevented from being applied to the trigger device 590 arranged on the arrangement member 570.

[0119] Other Embodiments Although the embodiments of the present invention have been described above with reference to the drawings, the specific configurations are not limited to these embodiments. The scope of the present invention is defined by the claims rather than the description of the above embodiments, and further includes all modifications within the meaning and scope of the claims.

[0120] In the above embodiments, a parachute or a paraglider was used as the projectile. However, the projectile may also include a lift-generating member, a net-like member for capture or entanglement, a fire extinguisher, a life preserver, medicine, etc. Examples of the lift-generating member include a parafoil, a Rogallo parachute, a single-surface parachute, an airplane wing, a propeller, and a balloon. Furthermore, if the lift-generating member has a control line, the safety device preferably includes a steering mechanism that can change the inclination angle of the launched lift-generating member using the control line. This steering mechanism may include, for example, multiple reels that reel in the control lines connected to the lift-generating member and a motor that powers the reels. The motor can be driven to reel in or release the control lines, thereby tensioning or loosening the lift-generating member as needed.

[0121] Furthermore, in the above embodiment, a gas generator is used as the power source, but the configuration is not limited as long as it is possible to impart a driving force to the sliding member for propelling the sliding member along the cylinder, and for example, an elastic body such as a spring may be used.

[0122] In the above embodiment, the case where at least a part of the actuator is located on the other side of the container has been described, but this is not limiting. For example, the entire actuator may be housed in the container, and the actuator may not be located on the other side of the container.

[0123] In the above embodiment, the arrangement member forms a space for accommodating the trigger device, but this is not limiting. For example, the arrangement member does not have to form a space for accommodating the trigger device, and may form a mounting surface for mounting the trigger device, or may form a recess into which the trigger device is fitted.

[0124] In addition, in the above embodiment, a safety device using a container including a bottomed main body and a lid having a cylindrical portion has been described, but this is not limited thereto. For example, instead of the container of the above embodiment, a container including a bottomed cylindrical portion having an opening at one end and a lid that closes the opening may be used for the safety device. In this case, the positioning member may be provided on the side (cylindrical portion) of the bottomed cylindrical portion via a vibration-damping member.
