Title:
EFFICIENT, NATURAL SLAT SYSTEM, COVERING AND METHOD
Document Type and Number:
WIPO Patent Application WO2002064935
Kind Code:
A3
Abstract:
The structres and process for producing the structures of theinventon enable extensive and efficeent use of block scrap for slat (91, 171, 205, 255) manufacturing. The techniques employed advantageously accomplish two goals simultaneously, enabling scrap, such as block scrap, to be formed into longer effective lenghts. Such longer effective lengths can then be cutably formed into slat (91, 171, 205, 255)s of various sizes. The joinder of the block scrap is by deeply extending, finite interlock lenght finger joints which, once the material is cutalby formed into slat (91, 171, 205, 255)s, remain as relatively shallow (the thickness of the slat (91, 171, 205, 255) and finite interlock lenght finger joints. TH joints have the added benefit that they statistically "break up" any grain differences which would otherwise create warp, and enable long lenghts of slat (91, 171, 205, 255) to be employed from several shorter lengths of scrap. An applied covering layer may be applied by wrapping or insertion. An ultraviolet resistant lacquer may be applied to the covering layer for long window life and attractive finish.
