US 12,221,832 B2 · Architectural-structure coverings, and components thereof

Abstract

An architectural-structure covering may include a covering moveable between retracted and extended positions, and between closed and open configurations. The covering may include front and rear sheets and a plurality of vanes extending therebetween. In the extended position, the covering may be configured so that the vanes are opened such that they are positioned substantially perpendicular to the incoming light. The architectural-structure covering may also include a rotatable member and an external booster movable between a first state of operation wherein the external booster stores potential energy and a second state of operation wherein the external booster releases the stored potential energy to rotate the rotatable member in a predetermined direction to effect additional rotation of a covering.

Dependent claims

An architectural-structure covering, comprising:

a rotatable member;
a covering operatively coupled to the rotatable member, the covering being movable between a retracted position and an extended position;
and
an external booster operatively coupled to the rotatable member, the external booster comprising:
a biasing mechanism operably associated with the rotatable member to selectively rotate the rotatable member in an extension direction, the biasing mechanism having a preload;
and
a retention mechanism associated with the biasing mechanism and operable to release the preload at the extended position;
wherein the external booster is spaced apart from the rotatable member, the external booster being coupled to the rotatable member via one or more gears arranged and configured to transfer rotation between the external booster and the rotatable member.
