Abstract: A fuel tank latch is disclosed for securing a pivotable gas tank on a motorcycle. The fuel tank latch provides a way to tilt up the fuel tank to access components located beneath the fuel tank. When in its normal, non-tilted position, the forward end of the fuel tank may be secured to the motorcycle's chassis.

The fuel tank latch may include a cover plate, a latch, a base plate, and an attachment plate. Example fuel tank latches according to the present disclosure may be configured to releaseably latch together the mounts and pins. A knob may be provided to allow operation of an internal latch assembly. The fuel tank latch may be used to secure components other than a gas tank to motorcycle.

Abstract: A fiber reinforced core panel is formed from strips of plastics foam helically wound with layers of rovings to form webs which may extend in a wave pattern or may intersect transverse webs. Hollow tubes may replace foam strips. Axial rovings cooperate with overlying helically wound rovings to form a beam or a column. Wound roving patterns may vary along strips for structural efficiency. Wound strips may alternate with spaced strips and spacers between the strips enhance web buckling strength. Continuously wound rovings between spaced strips permit folding to form panels with reinforced edges. Continuously wound strips are helically wrapped to form annular structures, and composite panels may combine both thermoset and thermoplastic resins.
