Abstract
An umbrella includes: a central shaft having a lower tube secured on a grip and an upper tube telescopically mounted on the lower tube, a plurality of umbrella ribs pivotally secured to the central shaft for securing an umbrella cloth thereon, a plurality of rib restoring springs respectively secured on the ribs for operatively automatically closing the umbrella, which is previously opened to tension the rib restoring springs for storing their restoring spring energy, a control device having a push button transversely slidably held in a grip and a closing actuator vertically slidably held in the lower tube having a pulling rod linked to a resilient latch for operatively retracting the resilient latch for uncoupling the upper tube from the lower tube when closing the umbrella, and a rope secured between the lower tube and a lower runner of the umbrella ribs by slidably winding the rope in an upper portion of the upper tube to be operatively tensioned on the rope when opening the umbrella to have a tendency for pulling the lower runner of the umbrella ribs and the upper tube towards the lower tube as restored by the rib restoring springs for helpfully closing the umbrella automatically, thereby providing an umbrella having an automatically closing mechanism with simple construction, easy production and convenient operation.
