US Patent 7066165 Center-fire bow

A bow includes a bow frame with a geometric center, and a window surrounding the geometric center. A bow handle is attached to the bow frame at a position offset from the geometric center, such that a user can fire an arrow through the window, through the geometric center of the bow. A gimbal may be disposed within the window, the bow handle being pivotally attached to the gimbal, so as to allow free pivoting of the bow about two substantially orthogonal axes.
