Motorcycle fork extension
Abstract
Abstract AN ELONGATED MEMBER IS CONNECTED TO THE TOP END OF A MOTORCYCLE FRONT FORK POST, AND BRIDGES THE DISTANCE BETWEEN THE UPPER AND LOWER BRACKETS OF A MOTORCYCLE FRONT END STEERING ASSEMBLY TO FORM A DOWNWARD AND FORWARD EXTENSION OF THE FRONT FORK. THE SAID MEMBER HAS SUBSTANTIALLY THE SAME CROSS-SECTIONAL CONFIGURATION AS THE POST, AND ITS BOTTOM END IS SHAPED TO RECEIVE THE TOP END OF THE POST AND HAS A THREADED STEM THAT SCREWS INTO A TAPPED HOLE IN THE POST. THE TOP END OF THE MEMBER IS FORMED TO SEAL WITHIN A CAVITY IN THE UPPER BRACKET AND HAS A LONGITUDINALLY EXTENDING TAPPED HOLE IN ITS CENTER TO RECEIVE A CAP SCREW, THE HEAD OF WHICH SEATS ON THE TOP OF THE UPPER BRACKET TO PREVENT DOWNWARD MOVEMENT OF THE MEMBER WITH RESPECT THERETO. WHEN THE EXTENSION MEMBER IS IN PLACE, THE LOWER BRACKET IS CLAMPED TIGHTLY TO THE UPPER END OF THE FORK POST, AND THE EXTENSION MEMBER SPANS MOST OF THE DISTANCE BETWEEN THE LOWER AND UPPER BRACKETS.
