Abstract
A rapid deployment and retraction telescoping mast system for controlling the height of a mast. A retraction mechanism including a resilient member, a retraction reel, a reel shaft, and a motor disposed about a frame. The resilient member extends from the retraction reel and is rigidly attached to a top tube of the mast through a sealed passage. The reel shaft rotates the retraction reel and winds the resilient member creating a retraction force on the top tube causing controlled retraction of the mast. A deployment mechanism including a compressor, storage tank, exhaust valve and isolation valve arranged about the frame and in communication with the mast. The compressor generates pressurized air to be communicated to the mast when the isolation valve is in the open position. The increase of pressure generated by the deployment mechanism provides a force within the mast thereby controlling its deployment.
