    摘要： SHELVING UNITS ARE MOVABLE ALONG GUIDE RAILS BETWEEN SELECTED END PORTIONS BY MEANS OF A LEVER SWINGABLY MOUNTED ON A SIDE OF EACH UNIT AND HAVING A LOWER END PORTION ENGAGEABLE WITH SELECTED, VARIABLY POSITIONABLE ABUTMENTS PROJECTING LATERALLY FROM ONE OF THE RAILS AND AN UPPER END PORTION PROVIDING A HAND GRIP FOR SWINGING THE LEVER ABOUT ITS PIVOT TO MOVE THE UNIT BY A LEVERAGE ACTION. THE PIVOT POINT OF THE LEVER IS ADJUSTABLE ALONG THE LEVER TO PROVIDE VARIABLE LEVERAGE.

    摘要： A tandem rider device and method of use for maintaining three planes of stability, elimination of interference and steering is presented. In particular, the present invention relates to devices and mechanisms, which when connected to the three planes of stability, vertical, horizontal and axial, between two duplicate personal transportation devices or between the transportation device and another device including structural stability elements provide for the following three enhancements. Provide tracking wheels, levers, springs and pedals for interference elimination devices allowing removal of tracking wheel interferences when two devices are connected together. Providing steering mechanism used for steering two duplicate personal transportation devices or steering the transportation device and another device when the tandem rider device is placed on a suitable surface other than parallel tracks. Providing a plurality of assemblies, that when such assemblies are removed, allow engagement of the steering mechanism when the transportation devices are removed from parallel tracks.
