Abstract
The invention refers to a system comprising a Venetian blind or the like housed within a double glazing or a double glass. The blind comprises a multiplicity of slats movable by means of a shaft rotatable around a longitudinal axis thereof and housed in a rolling-shutter box of the double glazing. The closure system comprises means for rotating the shaft around the longitudinal axis thereof. The rotation means are housed in a lateral profile of the double glazing and are commanded by a slider translatable between an upper end stop, at which the blind is completely raised, and a lower end stop, at which the blind is completely lowered. The closure system further comprises a first mechanism which prevents a movement of the blind until, during the transport or assembly of the closure system, the rolling-shutter box is disconnected from the lateral profile. The first blocking mechanism comprises three pins that can be rotated, together with the shaft, around the longitudinal axis thereof, and that can be translated between a first position at which the three pins are housed in three respective seats obtained in the cap of the rolling-shutter box, and a second position in which the thre…
