发明名称 Bumper block assembly for a rear bumper of a trailer
摘要 A bumper block assembly configured to be coupled to a bumper of a trailer includes a compressible bumper block including a generally horizontal bore extending from an outer surface of the bumper block to an inner surface of the bumper block and an outer cap coupled to the bumper block. The outer cap includes an outer wall engaged with the outer surface of the bumper block and further includes an aperture formed therethrough that is aligned with the bore of the bumper block. A bolt of the bumper block assembly is received through the aperture of the outer cap and the bore of the bumper block in order to couple the bumper block assembly to the bumper of the trailer. A spring of the assembly is positioned around a threaded end portion of the bolt in order to maintain the bolt recessed within the aperture of the outer cap as the outer cap and bumper block are moved between expanded and compressed positions.
