发明名称 Assit-a-lift
摘要 As briefly described in my CLAIM on page 29, my invention titled Assist-A-Lift, is the unique combination of my four separate custom-fabricated sub-assemblies herein described in this patent application that combine into a system that includes a pivot-type tongue hitch boat trailer. This trailer incorporates a fulcrum on the trailer located approximately 7 feet back from the original front 2 inch ball hitch that provides the necessary capability of the much-needed lever-effect luxury of clearance when backing uphill or on inclines where doorways are encountered. This is especially accommodating for persons with disability or handicapped individuals seeking this powered luxury tool and aid.
