There is provided a safety apparatus that not only has excellent safety performance but also has improved ease of accommodation of an ejected object in a container, and is capable of securing diversity of attachment positions to an aerial vehicle as compared with a related art, and an aerial vehicle including the safety apparatus. The safety apparatus includes a pilot chute ejectorand a main parachute storage. The pilot chute ejectorincludes an actuator, a push-up memberpushed up in one direction by the actuator, a pilot chutepushed up while being supported by the push-up member, a bottomed cylindrical containerthat accommodates the actuator, the push-up member, and the pilot chute, and a lidhaving a fan-shaped cross section that closes an opening end of the container. The actuatoris fixed at a position shifted from a geometric center of the fan-shaped cross section on a bottom surface of the containervia a base

Safety device and flight vehicle provided with safety device

There are provided a safety apparatus and an aerial vehicle including the safety apparatus, in which a lid and an opening end of a container are fixed before operation more firmly than a conventional art to be less susceptible to an external environment. A safety apparatus includes a piston member, a cylinder that accommodates the piston member and is provided with a bore through which the piston member protrudes to the outside during operation, a push-up member that is pushed up in one direction by the piston member, an ejected objectthat is pushed up while being supported by the push-up member, a gas generator that moves the piston member in the cylinder, and a lidincluding a projection. The projectionincludes a second through hole, and an engagement mechanism is configured when a pin memberis inserted into the second through holeand a first through holeprovided in a containerto engage an opening end of the containerand the projection

Safety device, and flying body provided with safety device

There is provided a safety apparatus including a push-up member in which an ejected object is hardly displaced even during transportation, and an aerial vehicle including the safety apparatus. A safety apparatusincludes a cylinderthat accommodates a piston memberand is provided with a borethrough which the piston memberprotrudes to the outside (upward in FIG.) during operation, a push-up memberthat is pushed up in one direction by the piston member, an ejected objectthat is pushed up while being supported by the push-up member, a gas generatoras a power source that moves the piston memberin the cylinder, a containerthat has a bottomed cylindrical shape and accommodates the piston member, the cylinder, the push-up member, the ejected object, and the gas generator, and a lidthat closes an opening end of the container. A movement preventing memberthat prevents the ejected objectfrom moving in a circumferential direction of a bottomed cylindrical portionis provided on an upper surface of a supportof the push-up member

Safety device, and flying vehicle provided with safety device

There are provided a safety apparatus and an aerial vehicle including the safety apparatus, in which a lid and an opening end of a container are fixed before operation more firmly than a conventional art to be less susceptible to an external environment. A safety apparatus includes a piston member, a cylinderthat accommodates the piston memberand is provided with a borethrough which the piston memberprotrudes to the outside during operation, a push-up memberthat is pushed up in one direction by the piston member, an ejected objectthat is pushed up while being supported by the push-up member, and a gas generatorthat moves the piston memberin the cylinder. A bottomed cylindrical portionof the push-up memberhas a hole, the holehas a substantially identical shape to a shape of one end of a rod, and the one end of the rodis fitted to the hole. The bottomed cylindrical portionand the rodare fastened and fixed by a bolt member

Provided are an ejection device with reduced weight without reducing an ejection speed of an ejected object and a flying object including the ejection device. An ejection deviceincludes a piston member, a cylinderwhich accommodates the piston memberand is provided with a hole portionfor allowing the piston memberto project outward during operation, a push-up memberpushed up in one direction by the piston member, an ejected objectpushed up while being supported by the push-up member, and a gas generatorwhich moves the piston memberin the cylinder, and in the ejection device, the push-up memberhas a support portiondisposed on a distal end side of the piston memberwith a tip of the piston memberin a moving direction of the piston memberset as a reference.
