摘要： This invention describes the design of a carrier system for people or goods permitting the continuous path of travel of a duo spiral escalator ascending and descending around a tower with a fixed diameter from the top to the bottom. At the bottom level and at the top level of the duo spiral escalator the invention consists of discontinuous upper and lower tracks for reversing the tread direction. Escalator chains connected to the tread support rods insure a smooth transfer of the treads between sets of tracks. This invention permits continuous transportation of the riders ascending and descending to a plurality of floors of varying ceiling heights. Current straight and spiral escalators have half of the treads carrying riders while the other half are empty as they travel back underneath. With this invention, as the treads move between floors, all of them may have riders aboard. This design saves horizontal space and requires fewer treads and materials than current escalators.
摘要翻译：本发明描述了用于人或货物的承运人系统的设计，允许二重螺旋自动扶梯的连续行进路线从顶部到底部具有固定直径的塔架上升和下降。在二重螺旋自动扶梯的底部水平和顶部水平处，本发明由用于反转胎面方向的不连续的上部和下部轨道组成。连接到胎面支撑杆的自动扶梯链确保轨迹组之间的胎面的平滑传递。本发明允许骑手上下连续地连续地运送到具有不同天花板高度的多个楼层。当前直的和螺旋式的自动扶梯有一半的脚踏车载着车手，而另一半是空的，因为他们回到下面。利用本发明，当胎面在地板之间移动时，它们都可以搭载乘客。该设计节省了水平空间，并且比目前的自动扶梯需要更少的踏板和材料。
