Abstract: A covering for an architectural covering is provided. The covering may include a rotatable outer roller, a rotatable inner roller, a first shade secured to the outer roller, and a second shade secured to the inner roller. The outer roller may define an elongated slot extending along a length of the outer roller and opening to an interior of the outer roller. The inner roller may be received within the outer roller and may define a central longitudinal axis. The first shade may be retractable onto and extendable from the outer roller. The second shade may extend through the elongated slot and may be retractable onto and extendable from the inner roller. The elongated slot may be substantially horizontally aligned with the central longitudinal axis of the inner roller when the first shade is in a fully extended position.

Abstract: A hem bar for use with an architectural-structure covering such as, for example, a rollable screen (e.g., an outdoor insect screen, a solar screen, a hurricane screen, a privacy and security screen, etc.).

Abstract: A scaffold includes a U-profile beam having an outwardly-open U-profile in which a scaffold platform is releasably hooked by mounting hooks. The U-profile beam has a perpendicular wall delimiting the U-profile and a guiding and fastening groove delimited by inwardly-extending groove reach-behind protrusions delimiting a locking space for releasably locking a locking element reaching behind the protrusions. An anti-lift-out and support element has an anti-lift-out element extending over the hooks to prevent lifting out. A support element fixed to the anti-lift-out element extends perpendicularly from the anti-lift-out element to a support element end for supporting the support element on the wall. The anti-lift-out element has a through-opening designed so that the fastening element moves the locking element toward the fastening element longitudinal axis and perpendicularly to the groove through the through-opening.

Abstract: A modular ladder having a single, central column for supporting radiating steps is shown and described. Steps are pivotally mounted on the central column to generate attachable modules. The steps fold up to a stowed position to minimize bulk when the ladder is not in use, and fold down to a nearly but not quite perpendicular position to facilitate climbing. The steps are held frictionally in the stowed position and by gravity in a deployed position when nearly perpendicular to the central mast. The ladder has a removable foot module for stability when propping the ladder on the ground. Each module bearing steps includes an integral loop for attachment of anchoring straps when desired.
