A rotary drive system for a roller blind. The drive system comprises a handle a worm gear, a bull gear, and a planetary gear drive system. The handle causes rotation of the worm gear, that engages the bull gear, that engages the planetary gear carrier of the planetary gear drive system. The sun gear of the planetary gear drive system is configured to engage the roller tube of the roller blind. Rotation of the worm gear causes a rotation of the bull gear which rotates the planetary gear carrier, causing the planetary gears to impart rotational motion to the sun gear and rotation of the roller tube at a rate faster than the rotation of the worm gear, said planetary gear carrier causing said planetary gears to impart rotational motion to said sun gear and rotation of the roller tube at a rate faster than the rotation of said worm gear.

A blind control for a window covering having a narrow profile; and particularly relates to a control module for a window shade where the location of the drive mechanism is selected to minimize the gap between the end of the window shade and inside edge of a window opening; locating the drive mechanism in a shell disposed in a housing to rigidify a reduced thickness of the drive so as to minimize the gap; and use a single rod depending from the control module to activate the drive mechanism in a safe and secure manner.

The invention also includes a housing with an end wall adjacent one end of the shade; a clutch projecting from said end wall and rotatable about a clutch axis, a drive gear engageable at one end of the clutch for rotatably driving said clutch and shade, said drive gear disposed in said housing adjacent said end wall; and a wand for driving said drive gear.

The invention provides for a wand to raise and lower the window shade.

Implementations of a roller blind assembly for angled architectural openings are provided. In some implementations, the roller blind assembly comprises a frame, a roller tube assembly, a roller blind sheet, a chain assembly, a track assembly, an extension assembly, a retraction assembly, and a motor assembly. In some implementations, a method of using the roller blind assembly comprises installing the roller blind assembly to fully fit the perimeter of an angled architectural opening and operating the roller blind assembly to fully cover the opening of the angled architectural opening.

A shutter adjustment device for utilizing a tool such as a drill to easily and effortlessly raise or lower storm shutters. The shutter adjustment device generally includes a housing adapted to be connected between a drill and a shutter lever of a storm shutter. The housing may be connected to a drill such that the housing rotates when the drill is activated. The shutter lever may be removably engaged within a clamp assembly of the housing such that the shutter lever may be easily rotated by activating the drill. In this manner, the shutter may be easily raised or lowered with little effort using the drill.

A main slat for a roller shutter system is provided. The slat includes a slat body having a first and second end, a hook end connected to the first end of the slat body, a screw boss connected to the second end of the slat body, and a receiving end connected to the screw boss. The hook end and the receiving end are each shaped such that the hook end is laterally insertable into the receiving end of an adjacent main slat and when so inserted forms a hinge. The slat body has a central cross section including at least first and second portions, the first and second portions each having a different radius of curvature.

In combination with a crank assembly, the improvement comprising an apparatus for improving operation of the crank assembly. The apparatus includes an an end cap of a predetermined material, an elongated extension member having each of a predetermined shape, a first predetermined length and formed of a first predetermined material, such predetermined shape includes a projection on one end thereof for engagement with one end of the crank assembly. A sleeve is disposed around at least a portion of the elongated extension member, such sleeve having a second predetermined length and formed of a second predetermined material. There is a means for securing the sleeve to the elongated handle member.
