PROTECTION DEVICE AND PROTECTION METHOD

WIPO Patent Application WO/2024/034419

A1

This protection device comprises an outer shell container, a protective body, and a driving unit. The protective body is provided with: frame assemblies that each include at least two frames which are disposed at a distance from each other at positions that are proximal and distal to an object to be protected and in a shape surrounding at least part of the object to be protected, and which are formed such that the distance therebetween changes when an external force is applied; and a connection part that connects the plurality of frame assemblies, which are disposed along a stacking direction. Prior to operation, the protective body is accommodated in the outer shell container in a state where the interval between the plurality of frame assemblies in the stacking direction is a prescribed initial distance. During operation, the protective body is driven by the driving unit such that the interval between the plurality of frame assemblies becomes greater than the initial distance, while maintaining a first frame assembly of the plurality of frame assemblies disposed in the stacking direction that is at one end, and a second frame assembly at the other end is made to protrude to a protection position.
