U.S. PAT. NO. 2,505,155
Inventor: Gordon K. Smith

A transparent closure device embodying a frame. A plurality of closure louvers are mounted in the frame to swing in a horizontal plane. End channels are for supporting the opposite ends of each louver. The louvers are formed concave-convex throughout the major portion of their length transversely. The terminal ends of each louver is formed flat transversely for engagement in the channels. The opposite longitudinal edges of the louvers are beveled at an identical angle throughout their length. The ends of the channels are closed and beveled at an angle identical to the angle of the edges of the louvers. The bevel of the channels engaging the bevel of the louvers form a continuous beveled edge throughout the louver and the channels. The louvers and the channels are adapted to overlie each other in beveled engagement when in the closed position, to provide an uninterrupted continuous surface to the closure device.

A louver having clear transparent C-shaped holding flanges for holding decorative panels. The transparent holding flange on each longitudinal edge of each louver in a vertical louver system is held vertical by a louver track system. The louvers are moveable from an overlapped closed position to an open position. Each louver has a main body portion of opaque material. The C-shaped holding flanges or edge portions include two transparent longitudinal edge portions, one on each longitudinal edge of the long louver. The transparent edge portion is equal in width to a transparent inwardly facing flange portion positioned over each longitudinal edge portion. The transparent edge portion and transparent inwardly facing portion are connected together and separated by a transparent mid portion of a width generally equal to the thickness of a decorative member. The transparent material allows the edges of an inserted piece of decorative material to be viewed through the transparent, inwardly facing portions.

Laminates particularly useful in vertical blind slat assemblies, and vertical blind slat assemblies utilizing the laminates are disclosed. The laminates comprise strand material which is not free hanging and in which there are substantial spaces between the strands to allow light to pass through the material, and a sheet-like layer to which the strand material is secured so that the strands of the laminate are fixed. The laminates allow the color or other characteristics of a slat member or insert to be seen. The laminates can have differing surface characteristics, (e.g. texture) and strand colors, sizes and patterns. The sheet-like layer can be transparent or translucent. A laminate can be secured directly, for example by adhesive, to a slat member having light-transmitting properties (e.g. opaque or translucent), surface characteristics (e.g. texture) and/or color which affect the overall appearance of the slat. A laminate can be removably secured to a groover slat member which can have light transmitting properties, surface characteristics and/or color which affect the overall appearance of the slat. An insert can be disposed between the laminate and the groover slat which itself has light-transmitting properties (e.g. opaque, translucent), surface characteristics and/or color or print which affect the overall appearance of the slat. The laminate allows the insert and/or slat member to be seen, to provide color, etc. to the slat assembly. The laminates allow a vertical blind slat to be assembled easily from a particular laminate and slat member, and insert if used. By stocking a limited number of laminates, slat members and inserts, a wide variety of slat assemblies can be provided. The laminates can have a plastic or fabric second layer to which the strand material is secured.

The triangular shape of the louvers allow light to pass through the first and second color-tinted adjacent sides to add a soft color hue to a room. The third side of the triangular louver is opaque and acts much the same as does a common blind when used to block the light from entering a room. The third side may, however, have a decorative scent or pattern on it to present a pleasant scene to the onlooker. The third side has a rotation restriction and alignment tab on it to align the third sides of the louvers, so that the decorative pattern or scene is clearly illustrated and that the louver is positioned to properly block the light. Each louver is removably attached to a support system in such a manner that the louvers may be rotated, to allow light to pass through two of the adjacent sides and then be rotated so that the opaque third side is parallel to the window or door and restricts the passage of the light.
SUMMARY OF THE PRESENT INVENTION
The instant invention relates generally to shade devices for windows and, more specifically, to a system for refracting light passing through a window while also dimming the light and allowing only opaque silhouettes to be seen therethrough on an outside of the window.
A primary object of the present invention is to provide a blind system that will overcome the shortcomings of the prior art devices.
Another object of the present invention is to provide a blind system including slat members which are at least partially light transmissive, similar to the optical effect produced by passing light through glass blocks.
A further object of the present invention is to provide a blind system which is easily and conveniently installed within an existing window frame.
A yet further object of the present invention is to provide a blind system having tinted slats for restricting the amount of light allowed to pass therethrough and refracting any light allowed to pass therethrough.
A still further object of the present invention is to provide a blind system wherein the slats refract light passing therethrough and allow only opaque silhouettes to be viewed therethrough.
An additional object is to provide a blind system wherein its slat members are positioned to extend either vertically or horizontally within the window frame.
An even further object of the present invention is to provide a blind system wherein the slats are color tinted to give a stained glass appearance.
A still further object of the present invention is to provide a blind system that is simple and easy to use.
A yet further object of the present invention is to provide a blind system that is economical in cost to manufacture.
Further objects of the invention will appear as the description proceeds.
A blind system for regulating light entering a window frame of a window is disclosed by the present invention. The blind system includes a support bar affixed to an interior top portion of the window frame, a plurality of prism shaped slat members connected to and extending from the support bar and a device for selectively pivoting the slat members to both change an angle at which the light passes through the slat members and change an amount of light permitted to enter the room through the slat members. The slat members are able to refract light passing through the window and thereby redirect light passing therethrough. The slat members are connected to extend either vertically or horizontally from the support bar. A device for adjusting a height of the slat members above a bottom side of the window frame is provided when the slat members extend horizontally. The slat members are also able to pivot within a 180° range of rotation. A device is also provided for regulating the height of the horizontal slat members or regulating the extension of the vertical slat members across the width of the window frame.
To the accomplishment of the above and related objects, this invention may be embodied in the form illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustra
