  • Publication number: 20020108723
    Abstract: The structures and process for producing the structures of the invention enable extensive and efficient use of block scrap for slat manufacturing. The techniques employed advantageously accomplish two goals simultaneously, enabling scrap, such as block scrap, to be formed into longer effective lengths. Such longer effective lengths can then be cutably formed into slats of various sizes. The joinder of the block scrap is by deeply extending, finite interlock length finger joints which, once the material is cutably formed into slats, remain as relatively shallow and finite interlock length finger joints. The joints have the added benefit that they statistically “break up” any grain differences which would otherwise create warp, and enable long lengths of slat 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.

  • Publication number: 20020026749
    Abstract: Several embodiments of the shutters employ a variety of synergistic features which may be used individually or in combination to produce a shutter capable of more completely shutting out light. One aspect is the use of a two-step overlapping end to provide a complementary fit in order to shut out light. Another aspect is the use of an angled engagement pin which engages the louver not at its edge, but into its main expanse and nearer the center of pivot of each louver. Another aspect is the use of an accommodation space to accommodate the “U” shaped attachment member of the simultaneous actuation handle, which accommodation space can vary in size and depth to accommodate structures extending from the simultaneous actuation handle. Regardless of relative size, the louvers, engagement pins, and simultaneous actuation handle can be disciplined to form a neater appearance on the shutter assembly.
