Window shutter blind cassette has rubber seals fitted to shutter and closing cassette slit in open and closed condition

摘要

A window shutter blind deploys from a spindle in an overhead cassette via an elongated slit. The shutter blind is assembled from a series of horizontal slats terminating at the lowest extremity in a batten located immediately after a rubber seal that locates in the slit on retraction. The shutter has a further rubber seal (4) that engages in the slit when the shutter is fully deployed.
