Abstract: A motor head cover for a roller shade that has an electric motor releasably secured to an end bracket by an insert plate. The motor head cover has a C-shaped body having a mouth opening and an outer circumferential surface. The outer circumferential surface has an inner body surface, an outer body surface, an outer, inwardly directed, side surface, and an inner, inwardly directed, side surface. Each of the side surfaces extend inwardly from the circumferential surface at approximately 90 degrees to collectively form a raceway with the inner body surface. The inner, inwardly directed, side surface is configured to be engaged about a circumferential lip on the insert plate to assist in releasably securing the motor head cover thereto. The inner, inwardly directed side surface, has a series of spaced apart notches that assist in a non-destructive flexure of the motor head cover when securing about the insert plate.

Abstract: A shroud for the drive chain of a roller blind. The drive chain has s a series of balls mounted on a cord or wire and is in the form of a pair of leg members forming a loop. The shroud comprises an elongate body having opposed open ends with an internal passageway extending therebetween. The body has an enclosed exterior surface extending between the open ends. A longitudinal internal baffle may extend between the open ends, segmenting the internal passageway into two longitudinal channels, each channel extending between the open ends and dimensioned to slidably receive one of the pair of chain leg members therethrough. The baffle may have a longitudinal slot extending along its length, where the slot is dimensioned to permit the receipt of the cord or wire of the drive chain, and is dimensioned to preclude the passage of the balls of the drive chain therethrough.

Abstract: A torque transfer coupler for a roller blind. The torque transfer coupler has a central body securable to an electric motor and includes one or more torque transfer elements engaging the interior of the blind's roller tube. The coupler includes an anti-slip member having one or more resilient portions having a rest position and a deflected position. When, in their rest positions the resilient portions have a dimension larger than the cross sectional area of the roller tube. When in their deflected positions and received within the roller tube the resilient portions engage the interior surface of the roller tube resisting the withdrawal of the torque transfer coupler, and the electric motor secured thereto, from the interior of the roller tube.

Abstract: An adjustment mechanism for a roller blind. The adjustment mechanism comprises (i) an adjustment spring housing securable to an end plate of the roller blind such that when so secured the housing does not rotate independent of the end plate, (ii) a balancing spring coupler at least partially receivable within the adjustment spring housing, the balancing spring coupler having an outer end securable to an end of a balancing spring of the roller blind, (iii) an adjustment spring, the adjustment spring transferring rotational torque between the adjustment spring housing and the balancing spring coupler, and (iv) an adjustment shaft positioned at least partially within the adjustment spring housing. Rotation of the adjustment shaft causes a rotation of the balancing spring coupler and the adjustment spring relative to the adjustment spring housing to increase or decrease the torsional loading of the balancing spring.

Abstract: A mount for a roller blind. The roller blind has a roller tube securable to a structure between first and second end brackets. In one embodiment the mount comprises at least one yoke and at least one axle member. The yoke is securable to the first end bracket and has a generally horizontally oriented throat. The axle member is releasably securable to a first end of the roller tube with at least a portion retainable within the yoke's throat when the axle member is generally horizontal. The receipt of the said axle member within the throat hangs the first end of the roller tube from the first end bracket while permitting the roller tube to pivot about the first end bracket in a generally vertical plane.

Abstract: 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.
