Title: Window blinds slat structure

Description:
BACKGROUND OF THE INVENTION  
      1) Field of the Invention  
      The invention herein relates to window covering products, specifically a window blinds slat structure that provides for use on doors and windows in which an original, innovative windows blinds slate structure enables products of higher quality and greater added value.  
      2) Description of the Prior Art  
      Conventional window blinds are comprised an upper support, a lower support, and a plurality of slats. Since the slats are plain surfaced and the design is uninteresting, the resulting weave design is limited and insufficiently variable to meet market requirements.  
      In view of the said situation, the applicant of the invention herein researched and developed a window blinds slat structure of novel design having product manufacturing utility, originality, and progressiveness which culminated in the development of the window blinds slat structure of the invention herein.  
     SUMMARY OF THE INVENTION  
      The objective of the invention herein is to provide a window blinds slat structure utilized as a horizontal louvered window shade in which a plurality of loops are unitarily knitted from warp yarns or weft yarns along the two sides of each slat, the loops providing for the insertion and positioning of long rods, thereby converting the original conventional cloth covered slats into changeable yarn woven slats and enabling the insertion of the long rods such that they are exposed outside the slats, with the slats and the long rods paired in different color combinations for a contrastive, multi-layer look that enhances the aesthetic appearance of the window blinds, which is the primary purpose of the present invention.  
      Yet another objective of the invention herein is to provide a window blinds slat structure in which the said window blinds slats can be utilized on Roman blinds, wherein a plurality of loops are unitarily knitted from warp yarns or weft yarns along the two sides of the slat and the twisted threads of a fringe extend downward in an intricate array from the one side of the slat; situated at the anterior extent of the loops, the fringe covers the space between adjacent slats such that after the slats are closed, no translucence occurs at the interstices, the said structure effectively serving as a sunshade.

     DETAILED DESCRIPTION OF THE INVENTION  
      Referring to  FIG. 1 , the isometric drawing of the window blinds slat of the invention herein, the window blinds slat  30  structure of the present invention consists of a knitted fabric, wherein the warp yarns and weft yarns are interlaced to form intricate lattice  33  lines, the slat  30  decorative pattern achieved by varying the intervallic distance and width dimensions between each lattice  33 , and loops  31  are unitarily knitted from the warp yarns or the weft yarns at predetermined intervals apart along the two sides of the slat  30 .  
      Referring to  FIG. 2 , the drawing illustrating utilization on a Roman blinds slat structure, a plurality of loops  31  are unitarily knitted from warp yarns or weft yarns along the two sides of the slat  30 , the twisted threads of a fringe  32  extend downward in an intricate array from the one side of the slat  30 ; the fringe  32  is situated at the anterior extent of the loops  31 , with the fringe  32  covering the space between adjacent slats  30  such that after the slats  30  are closed, no translucence occurs at the interstices, the said structure effectively serving as a sunshade.  
      Referring to  FIG. 3 .  FIG. 4 , and  FIG. 5 , the invention herein as utilized on a window blinds embodiment, the example application elaborated below: First, the said window blinds is comprise of:  
      An upper support  10  having a control mechanism for varying slat  30  angle and adjusting lower support  20  height.  
      A lower support  20  situated below the upper support  10 .  
      A plurality of window blind slats  30  having loops  31  unitarily knitted from the warp yarns or the weft yarns at predetermined intervals apart along two sides, the quantity of loops  31  increased or decreased as required.  
      Several long rods  40  that are individually inserted into the loops  31  at the two sides of the slats  30 , each long rod  40  fabricated of a hard but flexible plastic fiber.  
      Several ladders  50 , each connected to the said upper support  10  and the said lower support  20  and distributed along the two lateral edges of each said slat  30  and, furthermore, each said ladder  50  has two crosspiece cords  51  disposed at predetermined intervals apart, the quantity of which are equal to the amount of slats  30 ; when assembled, the first slat  30  is inserted between two crosspiece cords  51  (in the drawing, the area between the solid line and the invisible line), the remaining slats  30  then straddled on the two crosspiece cords  51  above (in the drawing, the invisible line area), enabling the opening and closing of each slat  30  by means of the ladder  50 ; said assembled components constituting a horizontal louvered window screen.  
      Additionally, if the problem of insufficiently level slats  30  is encountered, mounting components are installed at the two extremities of the long rods  40 , the mounting components are clipped onto the slats  30  to support them horizontally and thereby eliminate the insufficiently level slats  30  problem.  
      When the said window blinds structure is installed, the said long rods  40  are disposed outside the slats  30  and to improve the shortcoming of the prior art, the necessity of concealing the long rods  40 , the long rods  40  are colored to match slats  30  of different color to create a range of variegated combinations, the contrastive light and dark hues giving the window blinds a multi-layered look that enhances the aesthetic appearance of the window blinds, which is among the major effects of the invention herein.  
      In summation of the foregoing section, since the window blinds slat structure of the invention herein has manufacturing utility and, furthermore, is original and progressive, the present invention meets new patent application requirements. However, the said description only discloses the most preferred embodiment and shall not be construed as limitation on the scope and claims of the invention herein. Furthermore, all modifications and adaptations based on the application claims of the present invention shall remain protected under the claims of the invention herein.
