levolor blind tilt mechanism replacement

5,386,867 (see BACKGROUNDRelevant Prior Art Patent Summary), allow full tilt closure only in the street edge down position. Unlike the Venetian blind cloth ladder, the Peeping Tom's could peer through the miniblind's slat cord hole because the cord ladder did not cover the holes in the lowered close and tilt closed directions. The tilt open and tilt close operation is still initiated by a single, user operated tilt wand and internal to the headrail, tilt rod mechanism composed of a tilt rod which is attached to the tilt open/tilt close control cords through winches. This Wolfe patent concerns a horizontal window blind having slats with a T-shaped cord hole allowing individual slat removal and replacement or repair. I). Edge gap protection when the blind is mounted inside of the window casing is also not covered by this patent. The user simply raises open and lower closes the bottom board of the blind by hand to activate the self-ratcheting pulley. This object has not been met by prior art high privacy blind designs such as the Hunter Douglas (R) design or the Chen patent (U.S. Pat. Most clip based prior art inventions used metal clips which were of limited color choices. The raise open and lower close actions are done by vertical cords which are strung free play down either side of the cloth ladder. C). The Kraus patent is also more suited to exterior of window protective use of large, stiff, slats made of steel or glass. An advantage of the present invention is to provide such a device that is inexpensive to buy and inexpensive to manufacture. This shaping minimizes light leaks in a fully lowered close and tilt closed blind. The center columns have no slat cord hole and thus have no Peeping Tom problem. No mention is made of Peeping Tom prevention, although her invention solves part of this problem. Q). An advantage of the present invention is to provide such a device in the form of a clip (, F). An object and advantage of the present invention is to provide such a device that does not interfere in any way with the tilt closing (minimal light leaks), tilt opening and raising open the fully tilt open blinds (minimal stack height), or lowering close the fully tilt open blind. The Koch patent's tilt open/tilt close operation is performed by raising one ladder while lowering the opposing end's ladder. Upon one end of the tilt rod was attached a differential gear which attached to a free hanging customer activated, rotary action, tilt wand. The miniblinds used a raise open/lower close operation performed by a cord which was threaded free play down the center width hole with clearance of the slat and attached to the blind's bottom board. The alternative embodiment has no slat cord holes, but, has two opposing side, notched slats to act as guides for the free play raise open/lower close cord. Appears to be used in the Hunter Douglas, high privacy, Peeping Tom design (see above), but, US Patent markings as to this does not occur. The Levolor (R) Ultra Dark horizontal window blinds still produce an edge gap between the blinds and the window casing in certain types of blind mountings known as inside the window casing mountings. The Hauser patent also still has Peeping Tom access through the edge gaps made with the window casing. e) a window blind tilt open and tilt close mechanism. 5,386,867 (see below) assigned to Care Mate (R) International Company, Ltd. This is for child safety purposes to prevent accidental infant and pet strangulation. The edge gap problem still occurs for certain blind mountings done entirely inside of the window casing. The individual slats are removable for replacement or repair. Unlike Hunter-Douglas, it also provides for an edge covering strip to cover edge gaps made with the window casing. Also relevant in this regard is the amount of light leaks in a fully lowered shut and tilt close operation. The slats are cord hole and notch free, however, the interlocking U shaped clips create areas for light leaks by preventing a flush tilt closure of a slat upon the upper and lower adjoining slat. 4,341,254) (assigned to Levolor) provides a decorative solid, aluminum frame with edge cover protection.
