Laterally extendible mud flap mounting assembly for vehicles

A laterally extendible and vertically adjustable mud flap mounting assembly for a vehicle having a ball mount receiving box beam extending rearwardly from the vehicle, comprising in combination:

• an elongate central support box beam having opposing end portions and defining a medial channel extending therethrough, the central support box beam carrying a protruding mud flap extension stop spacedly adjacent opposing end portions and two spacedly adjacent depending fastening arms at a medial position, each fastening arms in a defining a plurality of opposed cooperating pairs of vertically spaced holes to carry releasable fasteners to fasten the central support beam orthogonally to the receiving box beam;
• two similar mud flap assemblies each having an elongate box beam mud flap extension slidably within each end of the medial channel of the central support beam to extend laterally therefrom with and a mud flap mounting arm carried by each mud flap extension to extend spacedly adjacent and parallel to the central support beam, and each mud flap mounting arm defining plural spaced holes to carry releasable fasteners extending therethrough to releasably fasten mud flaps to the mud flap mounting arms, and
• a collar carried by the laterally inner end portions of the mud flap mounting arms to slidably fit over and about the central support beam, and the collar defining a threaded hole extending therethrough to carry a threaded fastener therein to frictionally engage the central support beam to positionally maintain the mud flap assembly relative to the central support beam.
