In one aspect, an elongate mounting structure is elongated along a longitudinal direction and includes an elongate member having an elongate mounting member and a headrail member above the elongate mounting member. A longitudinal end of the elongate mounting member receives an extension mechanism to mount an architectural covering between two opposing mounting surfaces and the headrail member receives a drive assembly for operating a covering. The elongate mounting structure further includes an overhang part protecting from the elongate main member in a lateral direction, with the overhang part comprising an attaching section for attaching said covering to the overhang part such that the covering can extend substantially vertically in front of the elongate main member.

A counterbalancing device for a roller shade having a flexible sheet member and a roller shaft coupled to the flexible sheet member includes a stationary rod extending within the roller shaft, with the rod including a first end and a second end opposite the first end. The counterbalancing device also includes a rod adjuster coupled to the first end of the stationary rod and a spring winder positioned adjacent to the first end of the stationary rod. The rod adjuster is configured to selectively rotate the stationary rod and the spring winder is configured to rotate with the roller shaft. Additionally, the counterbalancing device also includes a spring having a first spring end coupled to the spring winder such that the first spring end rotates with the spring winder, and a second spring end coupled to the stationary rod such that the second spring end rotates with the stationary rod.

In one aspect, a spring assist module for a covering includes a torsion spring that is selected according to a protocol such that the torsion spring drives a driven part of the covering with a constant operating force. In another aspect, a roller blind includes a roller and a torsion spring operatively coupled to the roller, with the torsion spring having a spring characteristic(s) selected according to a protocol that matches the spring characteristic(s) to a torque curve associated with the roller blind to drive the roller with a constant operating force. In a further aspect, a method for selecting a spring for use within a roller blind includes determining a parameter(s) of the roller blind, determining a torque curve for the roller blind based at least partially on the parameter(s), and selecting a spring characteristic for a torsion spring of the roller blind that matches the torque curve.

A mounting element for mounting an architectural covering between two opposing mounting surfaces may include an elongate mounting member, and an extension mechanism operable between: i) a retracted state, and ii) an extended state in which the mounting element can be fastened to the architectural recess. The mounting element may also include an actuator rotatable about a rotation axis which is not parallel to the longitudinal direction, and a conversion mechanism to convert a rotation of the actuator into a translatory movement of the rotation axis along the longitudinal direction and vice versa. The extension mechanism is arranged to abut one of the opposing mounting surfaces in the extended state when the mounting element is mounted between the opposing mounting surfaces.

A mounting system for an architectural covering including a pair of mounting brackets, a roller operably connected to each of the mounting brackets, and an end plug at least partially received within the roller and operably connected to one of the mounting brackets. The end plug selectively transitions between an extended position and a retracted position and includes a sleeve, a plunger received within the sleeve, and a spring at least partially received within the plunger for biasing the plunger away from the sleeve. The plunger includes a center or body section and at least two radially spaced tongues extending from a first end of the center section. In the extended position a first portion of the plunger projects from the sleeve and in the retracted position at least a portion of the first portion of the plunger is received within the sleeve.

Roller blind mounting system and parts therefor

A system for attaching a shade material to a roller having recesses in its surface includes inserting portions of the shade material into an associated elongated recess and retaining the material in the recess with an attachment member having peaks and valleys along its length for intermittent engagement with the material within the recess.

Attachment of an architectural covering

A force transmitting coupling for drivingly coupling winding devices of adjacent architectural coverings. The coupling includes first coupling member, a second coupling member, and mating engagement means on the first and second coupling members adapted to establish mating engagement between the first and second coupling member to transmit a drive force from one of the first and second coupling members to another of the first and second coupling members. The second coupling member includes a hub and the engaging means on the second coupling member are resiliently connected to the hub.

Adjustable drive coupling for adjacent architectural coverings

A roller blind mounting system including at least one roller, at least one telescopic end plug and at least two brackets. The telescopic end plug is engageable within an end-opening of one of said rollers. The end plug includes a hollow body and a telescopically movable member or plunger co-axially positionable with respect to the hollow body such that a first axial extending length portion of the plunger projects from the hollow body and a second axial extending length portion is held within the hollow body. The plunger is telescopically movable between a first end position in which the first portion of the plunger projects from the cylindrical body and a second end position in which at least part of the first portion is inserted into the cylindrical body.
