ABSTRACT:
A pulley system for opening and closing an umbrella which has a ribholder adapted for slidable movement along an umbrella pole. A pulley wheel is mounted in the umbrella pole below its top portion with one end of a pulley cord fixedly attached to the ribholder while the other end of the pulley cord extends below the closed umbrella cover with a first cord handle adapted for being grasped by an operator. The first cord handle has a locking pin adapted for insertion into a hole in the umbrella pole for stopping the downward travel of the ribholder and supporting the umbrella in its open position. A second cord handle is secured to the pulley cord at a predetermined distance from the first handle such that the second handle can be readily grasped and pulled further downward for raising the ribholder to permit the locking pin to be inserted into the hole for locking the umbrella in its open position.
