器具の安全機構。A portable device that has a pair of guide rollers at the top and a braking means consisting of a fixed roller and a movable roller at the bottom, and is capable of safely descending by passing a descending rope between the guide rollers and the brake means. In the safety mechanism of the evacuation equipment, the above-mentioned pair of guide rollers 4, 5
Among them, on the same axis of one guide roller 4, a disk, a plurality of rotating arms functioning as centrifugal weights arranged along the circumference of the disk, and located between the disk and the inner circumferential wall of the casing,
A centrifugal friction mechanism 8 is provided, which is composed of a bearing ball that is held between the rotating arm and the inner circumferential wall of the casing during overspeeding, and generates a large frictional force that impedes this rotation as the rotational speed increases. A portable evacuation device characterized in that the step 6 is constructed by disposing two fixed rollers 16, 17 and moving a movable roller 18 to a position approximately in the middle of these fixed rollers 16, 17. safety mechanism.
