  • Braking device, and shielding device using same
    Patent number: 11168518
    Abstract: Provided is a braking device configured to release a cord in a non-bent state so that the operation force required to pull cords is reduced and the behavior of slats is stabilized during an automatic fall, and a sunlight shielding device using the braking device. A braking device for braking movement of a cord includes a movement converter configured to convert movement of a cord into movement of another member. The movement converter includes sandwiching object configured to allow the cord to be sandwiched. The sandwiching object is configured to change a sandwiched state so that the cord is sandwiched by the sandwiching object when the cord and the sandwiching object move relatively in one direction and the cord is released in a non-bent state when the cord and the sandwiching object move relatively in another direction.
