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.
