摘要:
A covering for an architectural opening with improved insulating properties in one embodiment includes face-to-face cellular insulative components defining a fabric with dual layers of cells with the fabric being retractably mounted in a headrail so as to either be rolled about a roller or gathered adjacent to the bottom of the headrail. A first component of the fabric includes a pair of spaced parallel sheets of material interconnected with horizontally-extending flexible vanes so as to define a plurality of horizontally-extending, vertically adjacent cells of generally rectangular cross-sectional configuration. A second component of the fabric is mounted on one sheet of the first component of the fabric so as to form a plurality of vertically adjacent drooping segments of fabric forming a roman-shade appearance. Single or multiple layers of the components can be used with or without the other type of component.
摘要:
A system for incorporation into a retractable covering that includes a flexible lift cord extending from a headrail to a bottom rail. The system includes a flexible protector of a length similar to that of an associated lift cord with the lift cord being operatively connected to the protector. The protector is in turn connected to a fabric extending between the headrail and the bottom rail at predetermined spaced locations so that any loop of protector formable is limited by the spacing between the locations at which the protector is connected to the fabric. The maximum size of a loop so formed in the protector and thus the lift cord associated therewith is insufficient to encapsulate a body part of a child or infant.
摘要:
An apparatus and associated method for manufacturing a window covering for an architectural opening. The apparatus includes a support structure handling assembly, an operating element handling assembly, and a vane handling assembly. The handling assemblies process the respective materials to an assembly station to attach one portion of a vane to the operating elements, and another portion of the vane to the support structure, allowing movement of one portion of the vane relative to other portion of the vane.

A wireless battery-operated window covering assembly is disclosed. The window covering has a head rail in which all the components are housed. These include a battery pack, an interface module including an IR receiver and a manual switch, a processor board including control circuitry, motor, drive gear, and a rotatably mounted reel on which lift cords wind and unwind a collapsible shade. The circuitry allows for dual-mode IR receiver operation and a multi-sensor polling scheme, both of which are configured to prolong battery life. Included among these sensors is a lift cord detector which gauges shade status to control the raising and lowering of the shade, and a rotation sensor which, in conjunction with internal registers and counters keeps track of travel limits and shade position.

An operating control system for a retractable shade including a roller reversibly rotatable within a headrail includes a clamp system for gripping an endless operating cord in a neutral position to prevent rotation of the roller and a tensioner if properly mounted in a fixed position will release the clamp system to permit rotation of the roller while positioning the runs of the endless cord in a closely spaced relationship to minimize the risk of an infant or child becoming entangled in the cord.

An operating system for a retractable covering for an architectural opening having at least a movable bottom rail and possibly a movable middle rail connected to a shade material includes control or guide cords extending from a head-rail for the covering to the bottom rail and extending through the middle rail. Manually operable locks are provided on the bottom rail and the middle rail to grip the cords as they extend therethrough and a take-up system is provided in the bottom rail that is biased so as to retain the cords in a taut condition during movement of the bottom rail or the middle rail. The bottom and middle rails are moved manually simply by manually releasing the manual locks provided thereon so that exposed control cords are alleviated.
摘要:
A control element for actuating an operating mechanism for a retractable shade. The retractable shade having a flexible operating cord retractable and extendable from the operating mechanism, the flexible operating cord having a free end. The control element is attached to the flexible operating cord and includes a core having a length, the core being stiffened along the length so as to resist becoming entangled and an upper end of the length that is attached to the free end of the flexible operating cord.

摘要:
A system for biasing or encouraging a sheet of material to gather in one direction when one edge thereof is moved toward an opposite edge utilizes a plurality of cords, fibers or yarns which are secured to one face of the sheet of material so that the material always gathers toward the face on which the cords or fibers are provided.
