  • Patent number: 4537237
    Abstract: Our sectional overhead door is allowed to louver through machine mechanisms we have designed. The door louvers allowing ventilation, natural lighting, privacy, and security. These features can be utilized while the door is in the closed position, still allowing for the door to be raised in its normal manner. The louvering angle can be adjusted and locked by the use of one lever, thus allowing for maximum security while in the locked and louvered position. The bottom section will not louver for the purpose of additional security. Through the use of louvering, the above features can be achieved without changing the outward appearance of the structure.

  • Patent number: 4535828
    Abstract: A thermally efficient window shade that folds into attractive pleats in the raised position. The shade is fabricated from a laminated insulating material composed of encapsulated air bubbles in combination with one or more skins. The shade folding properties are obtained by slitting the laminate partially through the laminate at predetermined locations. The disclosure includes modified versions of the laminated insulating material as well as shade configurations wherein numerous three-sided pockets are formed by the shade to provide small regions of stagnant air. The disclosure further includes apparatus for efficiently slitting a continuous web of the laminated insulating material.

  • Patent number: 4535830
    Abstract: One end of the retraction spring of a lateral-traction roller shade is fastened to an interior rod that is stationary once it has been installed. The other end of the spring is fastened to a carrier bushing that rotates on the interior rod. The shaft of the shade is attached to the bushing and one end of a retention and clamping spring that surrounds the rod is fastened inside the bushing in such a way that the spring will rotate along with it. The other end of the spring is positioned in the path traveled by a drive segment on a sheave when the shade is lowered and in front of a drive rib on the bushing that is also positioned in the path. The raising of the shade is thus facilitated by the retraction spring.
