Flying decoration

摘要

A flying decoration includes a drive unit, at least one object mount, a transport line and an idler pulley device. The drive unit includes a drive motor, a system controller and a speed sensor. The drive unit is retained above the ground in one location and the idler pulley device is retained above the ground in another location. A drive pulley is mounted to a drive shaft of the drive motor. The system controller controls the rotation of the drive shaft. Both ends of the transport line are secured to the object mount to form a transport loop. The system controller includes an automatic travel distance calibration program. The object mount includes a line tensioning device for reducing slack in the transport loop. One end of the transport loop is retained on the drive pulley and the other end is retained on an idler pulley of the idler pulley device.

1. A flying decoration comprising:
a drive unit includes a drive motor, a drive pulley and a system controller, said drive pulley is secured to a drive shaft of said drive motor, said system controller controls a speed and rotational direction of said drive pulley, said system controller alternates the rotation of said drive shaft between a clockwise rotation and a counterclockwise rotation, a plurality of holes are formed through said drive pulley; an idler pulley device includes an idler pulley; an object mount includes means for retaining an object and means for stopping rotation of said drive motor at each end of said object mount; a speed sensor for counting said plurality of holes during rotation of said drive pulley; and a transport line having a first end and a second end, said first and second ends of said transport line are secured to said object mount to form a transport loop, said drive pulley is engaged with a first end of the transport loop and said idler pulley is engaged with a second end of the transport loop, wherein said drive unit and said idler pulley device are retained above the ground, operation of said drive unit causes said object mount to have a substantially linear back and forth movement.
