Abstract
In accordance with one embodiment, a roof-raising/lowering mechanism for an A-frame style folding trailer comprises a mechanical lever arm assembly. The lever arm assembly is coupled to the rear roof section, which underlies the front roof section when such sections are in their lowered, overlapping positions. Thus, when the lever arm assembly is operated to raise the rear roof section, it pushes up the front roof section to its raised position. The lever arm assembly can be manually operated and/or power-operated using, for example, an electric motor as the power source.
