This Clark patent has no slat cord holes and no slat notches and so no Peeping Tom problem with the slats. 09,648,602, filed on Aug. 26, 2000 by Kawakita, Kevin. This design still has edge gap Peeping Tom (. All prior art blinds use curved slats with the curvature pointed face-down towards the floor. K). Replacement of individual slats is a desirable feature. The alternative embodiment has no slat cord holes, but, has two opposing side, notched slats. Each slat guide has an almost full length, vertical removal slot such that an individual slat can be unsnapped from its rung, lifted up, rotated into a vertical position, and slid out sideways out of the slat guide on one end of the window or the other end.
N). Also relevant in this regard is the amount of light leaks in a fully lowered shut and tilt close operation. The notched slats will allow light leaks. The Tuzmen Patents introduce huge increases in light leaks for a fully tilt closed and lowered closed blind. These U.S. patents in most cases concerned many different horizontal window blind devices using slats with no cord holes and some sort of tilt open/tilt close and or raise open/lower close mechanism. One or more vertical columns of tension clips is used across the blind width. There are various devices designed enhancing the general performance of window blinds having slats, such as venetian blinds which have existed since the 1800's. This objective has not been met by many prior art high privacy blind designs. The slats are cord hole free, however, the tension clip use on concave-down, curved slats will cause too large a stack height. This invention provides an edge device that prevents Peeping Toms (, L). 4,341,254) (assigned to Levolor) provides a decorative solid, aluminum frame with edge cover protection.
No. This prior device is unlike the current patent, which concerns a design-in approach done at the factory. The ladder assembly provides the tilt open/tilt close operation. An object and advantage of the present invention is to provide such a device which comes on newly factory built horizontal window blinds, which can be installed at the dwelling without the use of special tools or expertise. However, this slat guide will need some clearance with the window casing to allow for sideways sliding action, individual slat removal.
Especially important is full raise open/lower close operation. This invention provides a device which can be sold at the retail or discount store in components with slats of different lengths custom cut and sold separately from the frame integrated with control cord mechanisms.
The C-shaped wire clip on the bottom of a concave, open face down, slat will prevent full flush across the slat contact with both upper and lower adjoining slats, tilt closure causing light leaks. This will allow at the store custom length cutting of the slats for retrofit upon an adjustable length frame. An object and advantage of this invention is to have no necessity for tilt open/tilt close control cord rope ladder rungs which look like the steps upon a rope ladder of prior art horizontal window blinds. The horizontal slat is first rested upon the rung of the cloth ladder. The raise open/lower close cords were attached to sets of double pulleys hidden in the headrail just like the old Venetian blinds, but, on a smaller scale. This invention provides a clip device (. This is described in DETAILED DESCRIPTION-OPERATION Of THE PREFERRED EMBODIMENT, see FIG. An object and advantage of the present invention is to provide such a device that is inexpensive to buy and inexpensive to manufacture. An object and advantage of the present invention is to provide such a device that is easily removable in its entirety for cleaning or dusting of the window frame or the blind. This is the cord which raises and lowers the blind. Other U.S. patents have major problems with introducing light leaks in fully tilt closed and lowered closed blinds. Hunter Douglas (R), Ovation (R), and Levolor (R) have new (1999) anti-Peeping Tom or high privacy horizontal window blinds in the prior art and available for public use. The present invention relates generally to window coverings, and more specifically, to window blinds of the type having slats, control cords, and control cord holes in the slats. Disadvantages of the Schaller patent are that the color or decorative pattern of the frame is fairly permanent. An object and advantage of the present invention is to provide a device which can be sold at the retail or discount store in components with slats of different lengths custom cut and sold separately from the frame integrated with control cord mechanisms. Also in the tilt close directions, the slat overlaps the adjoining top or bottom slat's hole thus completely blocking through the cord hole Peeping Tom activity. A standard, prior art free play raise open and lower close control cord is threaded down the top middle bar of the T with attachment upon the bottom board.
The open side of the C-shape faces the floor. This invention has no necessity for tilt open and tilt close control cord ladder rungs which look like the steps upon a rope ladder of prior art horizontal window blinds. The special hardened, edge has an off center axis, small, slat cord hole which is on the street-facing, edge of the slat. H). Without further analysis, the foregoing description will so fully reveal the mechanism of the present invention that others of average skill in the prior art and knowledge of all prior art can adapt it for different applications meeting the claims of said invention. There is no stated intention to block out Peeping Toms (. The notches act as guides for the free play raise open/lower close cord. The slats rest upon the horizontal steps in prior art blinds. Mechanically efficient mechanisms with little waste of energy due to excessive friction and cord tangling or misdirection is important. This first Tuzmen patent covers a horizontal window blind having slats with no cord holes. H). However, the room-facing, tilt edge up operation does not fully tilt close the slats. Children and dogs often bend blind slats resulting in poor operation and an ugly crumpled slat appearance. O). H). An advantage of the present invention is to provide such a device that allows the edge cover strip to be easily removed for cleaning or altering colors of the edge cover strip. A vertical column of the room facing, front, tilt sleeve is also threaded free play with a second raise open and lower close blind cord which attaches to the bottom board. Customers do not like this limitation. An advantage of the present invention is that it provides a plurality of such clip devices (.
These raise open/lower close cord controls require a center-width positioned, slat with cord hole to pass the raise open/lower close cord through in a free play manner which cords are firmly attached to the bottom board. in which the clip is used as means to connect the cord hole free slats to the control cords and the control cords are connected at the top to the window blind head rail and at the bottom to the window blind bottom board and furthermore, the control cords are connected to a window blind raising and lowering mechanism and a window blind tilt open and tilt close mechanism. This Yu patent concerns a high privacy, horizontal window blind using a cord hole and edge notch free slat. The full-length, slat carrier tray can also cause greater stack height which is the height of the stacked slats when the blind is fully tilt open and raise opened. Slats without cord holes, but, with notches are used. The free-hanging, raise open and lower close control cord is replaced by a US and foreign patented, spring-loaded, self-ratcheting, internal pulley. A mechanism for frame construction with aluminum pieces is provided. The slats in this first Tuzmen patent might also get scratched by friction contact of metal clip upon aluminum slat. Slat clearance with this center raise open/lower close control cord during a tilt operation determines the shape and size of the slat cord hole. The metal ladder mechanism does the tilt open/tilt close operation. While these devices may be suitable for the purposes for which they were designed, they would not be suitable for the purposes of the present invention, as hereinafter described. This Judkins patent covers a horizontal window blind having slats with no cord holes, but, with slat edge notches to retain the blind cords. This invention provides a device that is easily removable in its entirety for cleaning or dusting of the window frame or the blind. 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. This Hauser patent covers a horizontal window blind having slats with no cord holes and no notches. The cloth sleeve, slat holder has a special hardened, edge added to the sleeve holding the slat. The raise open/lower close cords were attached to sets of double pulleys hidden in the headrail with the customer pulling the free hanging cords at one end of the headrail.
make single damaged slat changes easier. E). This patent uses a cloth ladder assembly for the tilt open/tilt close mechanism. Also the minimum stack height becomes too great. In the preferred embodiment, it consists of an open top, C-shaped, metal clip held with the C-shape open face up towards the ceiling through which the cord hole free slat is slid horizontally through and across the clip. This type of rectangular frame also works mostly for newly installed horizontal mini-blinds. 2). The entire assembly forms a metal ladder mechanism when viewed from the edges of the blind. The Roberts patent uses cord hold free slats which are held in place by a C-shaped clip which has the open part of the C-shape pointing towards the ceiling. This Continuation in Part Tuzmen patent unlike my invention has the problem of excessive light leaks in the fully lower closed and fully tilt closed operation. My invention avoids these problems. 60/244,034 filed Oct. 27, 2000. Minimal stacking height allows the most amount of full sunlight and fresh air through the fully opened blind.
U.S. patent application Ser. As mentioned just above, the room-facing, tilt edge down operation fully tilt closes the slats. The raise open/lower close operation is still initiated by a user operated, single, free-hanging, control cord which is attached through internal to the headrail pulleys to the raise open/lower close blind cords. The Walker patent in its preferred embodiment has no slat cord holes for Peeping Tom action and no notches for light leaks. In viewing the cord mechanism from the side which looks like a rope ladder, the slat tilt axis is located closer to the right side or street side tilt open/tilt close control cord and not on the center width of the slat. The raise open and lower close actions are done by vertical cords which are strung free play down either side of the cloth ladder. The Hauser patent also still has Peeping Tom access through the edge gaps made with the window casing. E). The problems with the Voss patent is that light leaks come in through the edge notches. This second Tuzmen patent is a Continuation in Part (CIP) of her first Tuzmen US patent, U.S. Pat. I). Stack height can greatly increase using ill-designed clips with often concave-down, curved slats. A free play raise open/lower close operation set of cords runs vertically down the slats with partial retaining by the slat edge notches.
