Abstract: 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.

Abstract: 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.

Abstract: A slat or vane for use in a covering for an architectural opening is suitable for use in either a horizontal or vertical orientation and in a horizontal orientation will not sag or droop, and in a vertical orientation will rotate uniformly along its length when rotated from end thereof. The slat is formed in a tubular configuration and has a base material of glass fibers bonded together in a thermoformable resin so as to maintain the arcuate curvature desired for the tubular slat or vane. The slat can be repeatedly deformed and will always return to its original configuration.

Abstract: Methods and apparatus to provide upper and lower travel limits for architectural opening coverings are disclosed. A disclosed architectural opening covering assembly includes a rotatable roller tube and a covering mounted to the roller tube. The covering is movable between a lowered position and a raised position. The covering is wound on the roller tube in the raised position. The covering assembly further includes a first limit nut located internal to the roller tube to define the lowered position, and a second limit nut located internal to the roller tube to define the raised position.

Abstract: A retractable covering in accordance with the present invention includes a head rail with a horizontally disposed roller and a pair of depending sheets from the roller which form part of a fabric which can be wrapped around the roller or unwrapped from the roller when moving the covering between retracted and extended positions. The sheets can also be moved with the roller between a closed position wherein they are in contiguous relationship and an open position wherein they are separated while remaining in parallel relationship. A plurality of cut-out vanes are formed in one sheet having a free edge thereof secured as with adhesive or the like to the other sheet. Accordingly, when the sheets are in the closed contiguous relationship, the vanes which are integral with one sheet become coplanar therewith but when the sheets are separated the vanes pivot to open a passage through the sheet from which they were cut to permit the passage of vision and light.

Abstract: A covering for an architectural opening includes a roller assembly having a rotatable roller secured to one edge of a sheet of flexible material with the opposite edge secured thereabove to a fixed location. The roller assembly is cradled in a cord ladder or cord ladder type element so one vertical run of the cord ladder is anchored and the other vertical run is raised or lowered to raise and lower the cradle thereby causing the flexible material to be wrapped around or unwrapped from the roller. The roller assemblies can be used individually or in combination with like roller assemblies and can further be used in combination with other covering products such as sheets of translucent or transparent materials like sheer fabric.

Abstract: An apparatus for stitching a fabric and/or attaching guide rings to the fabric for possible use in a covering for an architectural opening includes a lift bar to which a top edge of the fabric is connected so the fabric can hang into an underlying housing where a plurality of individually operated clamps are positioned. The clamps can manipulate the fabric as the lift bar is raised or lowered while horizontal tucks are formed in the fabric with a reciprocating tucker blade. A pair of traversing sewing machines are used to stitch a tuck and/or attach guide rings to the tuck in an automated operation.

Abstract: An apparatus for forming fabrics for use, by way of example, in coverings for architectural openings includes a system for handling single or multi-layered fabrics by suspending the fabric from a lift tower, threading the fabric through various clamp systems within a housing for the apparatus, and subsequently forming horizontal rows of hobbles, tunnels, and/or attached rings by gripping and releasing the fabric with a vacuum clamp, upper and lower clamps, and a tucker blade clamp while a reciprocating tucker blade forms horizontal tucks in the fabric. Hobbles can also be formed in one layer of the fabric through use of the vacuum clamp which gathers a portion of one layer of the fabric while the other layer is handled differently. In doing so, hobbles are formed between tucks in the fabric with the hobbles establishing a fabric resembling a Roman shade.

Abstract: A Venetian-style window blind (10) that resembles plantation style shutters is described. In a preferred embodiment, the headrail is shaped like the plurality of slats depending from it, is pivotally connected to the sides of a window frame by mounting brackets and has a hollow interior. Tilting of the plurality slats depending from the headrail is accomplished by vertically moving an actuator rod that is pivotally connected to the headrail. The plurality of slats are suspended from the headrail by a cord ladder to tilt in unison with the headrail. While tilting the blind assembly into the closed position, the headrail and depending slats also slide inwardly towards the windowpane. The slats are lifted through the actuation of a lift handle that is slidably attached to the actuator rod and contains therein a lock mechanism to hold the slats in a desired position.

After all operations are complete on a tuck, the fabric is raised a predetermined amount so that a repeated operation can be applied to the fabric at a predetermined distance below the first operation where by the fabric can be provided with rows of tucks forming tunnels to which guide rings are attached.

Abstract: A modular shutter blind system for a window blind application. A window blind is made to look like a window shutter by having airfoil shaped slats which traverse in toward the window when the blind is tilted closed and traverse away from the window and toward the room when the blind is tilted open in order to give the blind the clearance needed to tilt open while making it appear as if the window frame is the shutter blind frame. This traverse motion of the slats is accomplished by having the tilting axis along the centroid of the head rail move in and out while the blind is tilted closed or open respectively.
