摘要:
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.

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.

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.

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.

A slat or vane (30) 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 (30) 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 (30). The slat (30) can be repeatedly deformed and will always return to its original configuration.

A control system for a vertical vane covering for use in an architectural opening includes a headrail having an upwardly opening channel in which a plurality of carriers are disposed for sliding movement along the length of the headrail. The headrail is of a thin profile with only a minority portion of the carriers being positioned within the hollow interior of the headrail. The carriers are interconnected by a scissors-type linkage to effect uniform separation of the vanes when the covering is expanded across an architectural opening and each carrier includes a rack and pinion system for rotating the vanes suspended thereby. Unique mountings for the endmost vanes allow the endmost vanes to cover the ends of the headrail.

摘要:
A retractable cover for architectural openings having collapsible vanes includes a support structure in the form of a sheet of material, monofilaments, tapes, ribbons, cords, or the like, supporting an upper edge of a plurality of vertically spaced, horizontally extending vanes with the lower edges of the vanes in most embodiments of the invention being connected to operating elements adapted to raise the lower edges of each vane toward the upper edges to define openings or gaps between the vanes through which vision and light can pass in an open condition of the covering. Variations of the covering do not require movement of a lower edge of a vane relative to an upper edge but simply movement of some vanes relative to other vanes. The vanes can be made of materials having different flexibilities and where more rigid materials are used, creased fold lines can be established for desired operability.
