Abstract
Abstract A ramp assembly provides loading of small off-the-road vehicles onto, and unloading of such vehicles from the bed of a pick-up truck. The assembly includes a flexible support such as a sheet of lightweight chain link, cloth belting or the like which is connected at the upper end to the corner posts of the truck bed or otherwise secured to the truck and which is tensioned at the other end thereof by an elongate support member, connected at one end to the ball hitch on the truck. The connection to the corner posts is made by notched members which extend laterally from both sides of the flexible support to engage the walls of the posts.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
159 words
A ramp assembly for loading relatively small motorized vehicles on, and unloading such vehicles from, the loading bed of relatively larger motorized vehicles of the type including a ball hitch so that such a relatively small vehicle can be transported by the larger vehicle, said ramp assembly comprising: a flexible support sheet which, in use, extends between the bed of the larger vehicle and the ground to form a ramp, said support sheet being of a flexible construction which is capable of being rolled up when not in use; means for securing one end of the support sheet on the bed of the larger vehicle; and means, comprising an elongate tensioning member extending between the larger vehicle and the other end of the support sheet, for tensioning and supporting the support sheet so that the support sheet is held taut and thereby forms the ramp, said elongate tensioning member including means engaging the ball hitch of the larger vehicle.
