Abstract: The invention is an automatic safety device for opening and closing an umbrella. The device is disposed within the grip body of an umbrella and includes a reel member, a ratchet, a coil spring, a rocker, a reset spring and a dragline. The reel member is secured to the ratchet and coil spring and is rotatably mounted about a reeling axis. When an umbrella is fully closed, the sidewall of a step-cone within a central shaft engages the releasing convex causing a pawl to disengage from the ratchet. The dragline is tied to the reel member and to the upper nest at the top of the umbrella. When closing the umbrella, the central shaft is only allowed to move downwards as restricted by the unidirectional feature of the ratchet. When the downward force is removed, the dragline holds the central shaft in position, thereby avoiding sudden deployment of the umbrella.
