Automatic flag unfurler |
摘要 |
An automatic flag unfurling apparatus for use on a flag pole contains a ribbed, lightweight, hollow tube containing strategically located notches in a longitudinal rib extruded integral with the parent plastic tube. Plastic cable ties, inserted into the flags eyelets, engage the notches and retain the flag in its preferable free-flying position. A lower friction reducing washer and retaining collar are firmly positioned on a stationary flag pole to prevent the tube/flag combination from sliding down the pole. The tube/flag combination is free to swivel due to wind forces acting on the tube/flag combination, and regardless of wind direction, freely swivels allowing the flag to remain in an unfurled state.
