Abstract
An arrangement for raising and lowering relative light weight objects from a ground position to a high storage position. A bracket is secured to the high storage position and supports a vertical rotatable shaft, with a pair of horizontal reels and an automatic lock position. A rod is detachably attached to the shaft and extends horizontally downwardly to the ground position. Rotation of the shaft around its central axis causes rotation of the reels. The reels are affixed to two lines which extend generally horizontally from the reels, with the free ends of the lines extending over spaced pulleys and extending downwardly for attachment to the ground level. Rotation of the shaft allows raising and lowering of the object. A spring loaded mechanism associated with the shaft causes automatic locking of the reels in any position, and locks the reels upon raising to the high storage position. The spring loaded locking mechanism is responsive to a slight downward pull on the shaft to an unlocking position, and release of the shaft causes the reels to automatically lock.
