Abstract

The safety stop, intended to prevent a roller shutter from falling suddenly, has a circular housing each end of the carrier spindle, supporting it in bearings, with a circular plate mounted on a sleeve around the spindle, rotating with it, and carrying a set of radial slots housing a set of rollers each with a bush mounted on each end, to locate the rollers in the slots, and these rollers are thrown outwards by centrifugal force when the spindle reaches a given speed to engage a set of forked abutments extending inwards from the interior of the housing.
