Abstract
A safety device capable of rapidly inflating a float, having sufficient buoyancy at the time of landing on water, and being lighter than a conventional safety device, and a flight vehicle including the safety device. A safety device includes a parachute, a bottomed cylindrical container that accommodates the parachute, and an ejection device that is provided in the container and ejects the parachute to the outside of the container. The parachute includes an umbrella body, a plurality of lines, a center cord, and a bag-shaped member. The bag-shaped member including an intake port connected to a ventilation port is provided outside a top portion of the umbrella body. The intake port of the bag-shaped member is provided with a check valve including a hinge portion and a plate member.
Claims10
A safety device comprising:
- a deployable object, the deployable object being deployable by being ejected into midair and being formed with a ventilation port that opens when deployed;
- a container that accommodates the deployable object;
- an ejection device that is provided in the container and ejects the deployable object to an outside of the container;
- a bag-shaped member provided on an outer side of the ventilation port and including an intake port through which air is taken in through the ventilation port;
- a plurality of lines having one end connected to an edge of the deployable object, and another end connected to the container or a payload outside the container;
- and
- a center cord having one end branched into a plurality of portions from a middle and connected to an edge of the ventilation port or an edge of the intake port, and another end connected to the container or the payload,
- wherein the deployable object and the bag-shaped member are ejected by an operation of the ejection device, and tension is applied to the center cord, so that the intake port is opened, and
- wherein the bag-shaped member is provided with a check valve at the ventilation port or the intake port.
