A trailer rail assembly includes a base plank with a planar top surface raised above a horizontal plane and extending along an entire longitudinal length of the base member. Such a base plank has a U-shaped cross-section. The assembly further includes a cylindrical shaft with an annular cross-section spanning along an entire longitudinal length of the top surface. A support plate is statically and fixedly attached to the shaft and spanning along the entire longitudinal length of the base plank, and a mechanism for simultaneously rotating the shaft and the support plate in sync and about a fulcrum axis extends along an entire longitudinal length of the shaft while the base plank remains statically affixed at a stationary position.

What is claimed as new and what is desired to secure by Letters Patent of the United States is: 1. A trailer rail assembly for supporting objects on a vehicle trailer, said trailer rail assembly comprising:a base plank having a planar top surface raised above a horizontal plane and extending along an entire longitudinal length of said base plank;a shaft having an annular cross-section and spanning along an entire longitudinal length of said top surface; anda support plate statically and fixedly attached to said shaft and spanning along the entire longitudinal length of said base plank; andmeans for simultaneously rotating said shaft and said support plate in sync and about a fulcrum axis extending along an entire longitudinal length of said shaft while said base plank remains statically affixed at a stationary position;wherein said simultaneous rotating means comprisesat least one bracket statically mounted to a portion of the vehicle trailer adjoining an end of said base plank, said bracket having a raised central portion monolithically formed with a pair of oppositely seated lowered flange portions, said central portion having an orifice formed therein and passing from an anterior surface to a posterior surface of said bracket at a height above said flange portions;a zerk fitting traversing through a side of said central portion and extending along an entire inner perimeter of said orifice;a lubricant inserted into said zerk fitting; anda fastener connected to an entrance port of said zerk fitting such that said zerk fitting is maintained at a stable and static position;wherein an end of said shaft is rotatably interfitted within said orifice and arranged in such a manner that an outer circumference of said end of said shaft directly rubs against said zerk fitting and said lubricant to minimize a frictional force during operating conditions.
