Improved arrangement for the closure of openings

摘要

Arrangement which comprises a roll-up or self-rolling-up laminar portion inside a slat of the successive slats which make up a slat-type closure for openings. Said laminar portion is arranged consecutively between pairs of slats in the succession of slats provided in the closure for openings. Rolling-up of the laminar portions is actuated by means of a single actuator, generally coincident with the slat actuator. The invention is for use in closures of openings constructed from slats connected together by a simultaneous movement in response to a single actuator. <IMAGE>
