Abstract
The present invention relates to an umbrella and includes a cover, a shaft of multi-sectional tubes, a notch, a runner, main ribs, and stretchers. A fixed sleeve is disposed outside an engaging complex that is disposed on the top portion of a sectional tube of the shaft having the smallest diameter, thereby enabling the engaging complex to slide up or down inside the fixed sleeve. The notch connects with an upper end of the fixed sleeve and the runner is disposed outside the fixed sleeve thereby enabling the runner to slide up or down outside the fixed sleeve. The fixed sleeve of this invention forms an elongated and strengthened part of the shaft to firmly support the umbrella when opened and stores multiple or all sectional tubes of the shaft when fully collapsed.
