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.
摘要翻译：如我在第29页的CLAIM中简要描述的，我的发明名为Assist-A-Lift是本专利申请中描述的四个独立的定制子组件的独特组合，其组合成包括枢轴式舌头挂车拖车。这款拖车在距离原来的前2英寸球形挂钩大约7英尺的拖车上装有一个支点，这样可以提供必要的能力，即在上坡时或斜坡遇到门槛的情况下提供急需的杠杆效应。这特别适合残疾人士或残疾人寻求这种动力的豪华工具和援助。
