Venetian blinds include a pair of slat lift and guide tapes (27, 28) that extend from the upper rail (12), downwardly through openings (22) in the elongated parallel slats (14) and into the lower rail (13) where they are collected in the lower rail on spools (48). The lift and guide tapes are concave in cross section when in their rectilinear shape and progressively change to flat in cross section as they are pulled into the lower rail and wrapped about tape collector spools.

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 three pins lie outside said seats. While the rolling-shutter box is disconnected from the lateral profile, the three pins are housed in the respective seats so as to prevent a rotation of the shaft for moving the slats. The closure system also comprises three counter-pins integrally connected to the lateral profile and arranged in a manner so as to push the three pins outside the respective seats upon connection of the rolling-shutter box to the lateral profile, so as to allow a rotation of the shaft for moving the slats. The closure system finally comprises a second mechanism for blocking the slider when the latter is situated at the upper end stop, i.e. when the blind is completely raised.

A hold down device is provided for continuous loop cords or bead chains in a window covering installation. The hold down device engages the cord or chain while the cord or chain is loosely suspended, and prevents operation by encountering the head rail if the cord or chain is operated. Mounting the hold down device in a window covering installation disengages the hold down device from its secured position relative to the cord or chain.

A motorized window treatment system may include a roller tube, a flexible material, a motor drive unit, and mounting brackets. The mounting brackets may include a stationary portion configured to be attached to a structure surrounding a window. The mounting brackets may include a movable portion configured to receive an end portion of a housing of a motor drive unit. The movable portion may be configured to operate the motorized window treatment between the operating position and the extended position in a circular-shaped path. A portion of the motor drive unit may be accessible when the motorized window treatment is in the extended position. The mounting brackets may include a stopping mechanism that is configured to prevent the motorized window treatment from extending beyond the extended position.
