Abstract
A ramp leg guard for use with livestock trailers and the like including panels which are automatically positioned and latched along at least one side of a ramp structure when said ramp structure is moved to an open position for loading or unloading of the trailer. In one embodiment a single panel is provided on each side of the ramp with said ramp being used with a trailer of drop-center, pull type. In another embodiment double panel structure is provided on only one side of the ramp with the other side of the ramp being enclosed by the side of the trailer. Both embodiments employ spring loaded hinges to automatically retract the guard panels and the ramp structure as well as latch mechanism for positively retaining the guard panels in tight engagement with the ramp structure in the extended position.
