Abstract

The invention discloses a safely foldable automatically expanding / collecting umbrella, which comprises a telescopic umbrella middle rod, an expandable umbrella rib device and a ratchet and pawl device, wherein the ratchet and pawl device is arranged in the umbrella head. The spindle of a ratchet is provided with a rope; the ratchet is connected with a clockwork spring; the clockwork spring is tightened when the ratchet rotates counterclockwise, and the ratchet rotates clockwise when the clockwork spring is loosened; and a ratchet spring which is used for driving a pawl to match with the ratchet is arranged in the umbrella head. When the middle rod is pressed in an umbrella closing process, under the braking action of the pawl, the ratchet only can rotate clockwise; and under the action ofthe clockwork spring, the ratchet rotates clockwise to collect the rope, wherein if the middle rod is incautiously released in the clockwise rotation of the ratchet, the rope is tightened but the ratchet cannot rotate counterclockwise, so the rope can fix the middle rod to prevent the middle rod from being sprung off. Therefore, the safely foldable automatic expanding / collecting umbrella has the effect of safety protection.
