Abstract: A semi-automatic umbrella includes a telescopic central shaft, a handle, and a runner slidable along the shaft. A first pull cord is placed in a tensed state when the shaft is extended, which causes an upward biased movement of an actuating member to thrust a spring-biased runner-retaining member to disengage from the shaft once the first pull cord is released. A tension spring body coupled to a second pull cord is stretchable to acquire an urging force. The stretched tension spring body enables an upward movement of the runner for spreading the umbrella. Once the urging force is released, a downward movement of the runner causes collapse of the umbrella and disengagement of a spring-biased shaft-retaining member from the shaft, thereby permitting folding of the shaft and closing the umbrella.

Abstract: A control device is applied to a base of an umbrella stem. A buckle sits in the base whose upper portion sets a controlling device controlled by the buckle and whose lower portion radially disposes a spool disk. The peripheral wall of the spool disk having ratchets defined thereon is embraced by a spool groove. Two ends of a spiral spring are respectively fixed to the base and the spool disk to generate an elastic force driving the spool disk's rotation. A shift block positioned under the base of the controlling device has a continuous torsion to contact the spool disk and clasp the ratchets. A disk cord provides one end fixed on the spool disk and wound around the spool groove and the other end penetrating the controlling device and the base to join an upper accommodation of the umbrella.

At the opening/closing motion of the umbrella, in response to the umbrella closing operation (umbrella opening operation) to an operation part provided in the lower part of the umbrella, the circular pipe which extends toward the operation part is driven in the direction in which the lower ring approaches (separates from) the upper ring. Consequently, the umbrella opening operation and umbrella closing operation using a single hand become possible in a simple structure.

Abstract: A protective mechanism for automatic umbrella includes a drive stem, a pulley tackle, a spring motor, a clutch, and a clutch spring; wherein, the drive stem is pivoted beneath the telescopic stick, and a hooked head in the telescopic stick controls a downward movement. The pulley tackle is pivoted beneath the drive stem. A strand has on end fixed to the pulley tackle and the other end secured to an upper notch of the umbrella. The spring motor is installed on the pulley tackle. The clutch is disposed under the pulley tackle. The clutch plate and the clutch spring are consecutively installed at a lower part of the drive stem. Confronting the clutch and the pulley tackle, unidirectional slant gears are able to cooperate with each other.

Abstract: The present invention pertains to a protective mechanism for automatic umbrella mainly including a drive unit, a pulley tackle, a spring motor, a clutch, and a clutch spring; wherein, a strand has one end fixed to the pulley tackle and the other end secured to an upper notch of the umbrella, and the spring motor and the clutch are separately mounted on the pulley tackle. Further, between the clutch and the pulley tackle are unidirectional rotor members cooperating with each other. Thus, the drive unit and the clutch spring substantially control the separation and contact of the clutch and the pulley tackle for either releasing the strand and tightening the spring motor while stretching the umbrella or winding the strand in a single direction and loosening the spring motor when collapsing. Therefore, the present invention prevents from striking users by taking off the umbrella stick halfway when manually retracting it.

And, the system can also be dynamic, such that it's also resistant to external forces, such as the wind.

Abstract: A protective device for automatic open close umbrellas is revealed. The protective device includes a ratchet mounted in a handle and rotating elastically for retracting or releasing a string, a string whose bottom end is fixed on the ratchet while a top end is fixed on an outer tube of an umbrella shaft or a core tube, and a locking member that is reverse L-shaped and is arranged with an elastic member for turning back therein. The locking member includes an upper part, a lower part, and a middle axle, used as a first-class lever. The upper part is against the bottom of the umbrella shaft so that the fastener can lean against a top surface of the upper part. When the umbrella shaft is gradually folded, the top surface of the upper part of the locking member is separated from the fastener while the bottom of the lower part is locked to one of the ratchet teeth of the ratchet elastically so as to achieve anti-springing effect.

Abstract: A guy structure for an automatic unfolding and folding umbrella is provided. The guy structure includes two or more guys: One guy is a lower nest guy, provided at least between a middle rod and a lower nest; the other is an unfolding guy, provided at least between the middle rod and a spreading component in the umbrella head. While unfolding the umbrella, an unfolding spring stretches and opens part of the middle rod pipe. The unfolding guy pulls and opens the rest section of middle rod pipe with the cooperation of the lower nest guy, and forms the complete unfolding status. While folding the umbrella, the folding spring makes the lower nest move downward under force of the folding spring. At this time, the unfolding spring does not generate tension on the middle rod pipe above it, thus the middle rod pipe above the unfolding spring can be collected through the lower nest guy or the unfolding guy.
