A vertical blind apparatus having a wand operated control for traversing the slats along a headrail and for rotating the slats. The blind apparatus has an actuator shaft with its axis disposed in a central vertical plane equidistant from the sidewalls of the headrail; slat carriers are mounted on slat carriages for rotation about vertical axes disposed in the central vertical plane and a control shaft for the wand operated control is also mounted for rotation in the central vertical plane. The wand operated vertical blind apparatus can be used in either left or right draw installations and in two-way draw installations.

Vertical blind

A vertical blind apparatus of the type having a plurality of panel support carriages mounted for movement along a track and a lazy-tong linkage extending lengthwise of the track and connected to the carriages to control spacing between adjacent carriages when the blind is extended along the track to a closed position. The maximum spacing between adjacent carriages is further controlled by rail engaging fingers on the outer pivots of the lazy-tong linkage, and a rail having lateral guide faces arranged to engage the fingers to limit movement of the outer pivots to a preselected minimum distance.

Vertical blind apparatus

A vertical blind of the type having louver carriages mounted for movement along a guide channel with a louver carrier mounted on each carriage for rotation about an upright axis and carriage gear mechanism for rotating the louvers in response to turning of an operating shaft that extends lengthwise of the channel. A wand operated mechanism is provided for rotating the louvers in response to raising and lowering a wand and includes a drive lever mounted for pivotal movement about an axis parallel to the axis of the operating shaft and a crank lever rotatable with the shaft and operated by the drive lever to rotate the shaft. A bidirectional detent mechanism on the housing and crank lever releasably retains the shaft in different angularly adjusted positions. The wand includes a tubular member connected to the drive lever through an L-shaped connector so that tubular member extends downwardly from the underside of the channel in all operating positions fo the drive lever.
