Abstract: A motorcycle flag holder mountable on a rear axle nut includes a main body formed from plate stock having spaced-apart first and second major planar surfaces. The main body has a regular-duodecagonally-shaped nut-securing aperture with a central an axis perpendicular to the major planar surfaces. The nut-securing aperture is sized to slide over the axle nut. The main body incorporates a slit that begins at an outer edge of the main body and terminates at an edge of the nut-securing aperture. First and second opposing portions of the main body on either side of the slit can be drawn together with a nut-securing bolt, thereby causing the nut-securing aperture shrinks in size and tighten around the axle nut. The main body also includes a flag staff retaining bore in which a flag staff may be secured with a thumb screw.

Abstract: A flag holder for vehicles—such as motorcycles and all-terrain vehicles—mounts on a generally horizontal panel having a bolt hole stamped, punched or drilled therein. For a preferred embodiment of the invention, the flag holder includes a cylindrical main body having an axially-aligned cylindrical aperture for receiving the staff of a flag. The holder also includes a hollow threaded retaining fastener that is coaxial with the cylindrical aperture. A staff ejector pin, retained within the hollow threaded retaining fastener, may be employed to eject a broken end of the flag staff. Two alternative embodiments are provided. The first utilizes a threaded main body and a hollow retainer bolt. The second utilizes a threaded hollow stud and a nut.
