Abstract: A mud flap lifting system for trucks pushes the mud flaps from their inside surface upward and rearward away from the rear tires. Push bars swing about a pivot from the underside of the truck body directly behind the mud flap. The push bars include C-shaped arms which receive the upper portion of the folded mud flap as it is retracted. Fully retracted, the mud flap is compactly folded so that it is less susceptible to damage. The lift mechanism is pneumatically powered by a single centrally-located cylinder which actuates twin linkages on either side of the truck through a transverse pivoting axle so that both mud flaps may be retracted simultaneously by a single pneumatic actuator.

Abstract: A splash guard or mud flap comprising a flexible, splash-intercepting body portion which may be fabricated of a material such as rubber or plastic or metal, and which is supported on and maintained in a preselected position on the fender of a vehicle by means of anchoring members adapted to be engaged along the fender of the vehicle. The anchoring members have a projection or pin-like member thereon for engaging and retaining the flexible, splash-intercepting body portion on the anchoring members. In a preferred embodiment of the splash guard, the body portion is fabricated of a material such as rubber or plastic which can be fully penetrated by the pin-like member utilizing only finger pressure. Locking means in the form of a push-on type nut advantageously is provided for the members. The splash guard, in its preferred form, can quickly and properly be positioned on the fender of a vehicle without the need for any tool.

Abstract: A retractable wheel flap-mounting assembly for dump trucks which includes a rigid supporting member fixed to the rear edge of the bottom of the dump truck body and having a pair of flap-mounting slides slidably mounted on said supporting member with means for moving the slides inwardly into retracted position when the dump body is to be dumped.
