Abstract:
1. An umbrella comprising: a mast to be inserted on a ground; a trigger located inside the mast, the trigger retains a runner on the mast; a closure system including a security system for closing the umbrella in case of lifting of the umbrella, the security system comprising: a triggering system located on a contact area of the mast with the ground, the triggering system comprising a slider, a slider return spring, and a flexible transmission assembly connected to the head of the slider; a mechanism to inactivate the triggering system, the mechanism including a cam pivotally mounted on the trigger, the cam is capable of resting against the mast, the cam being connected to said flexible transmission assembly, a pole for contacting the ground, the pole is retractable in the mast; wherein when a downward end of the umbrella leans against the ground, the weight of the umbrella compresses said spring and the slide is an active upper position in which said cam does not press against the mast; when said downward end of the umbrella does not lean against the ground or when the wind tends to lift the umbrella, said spring expands and pushes the slide to a lower triggering position in which said flexible transmission assembly is tensioned, which causes the cam to rotate and to bear against the mast, thereby inducing the withdrawal of the trigger inside the mast ensuring the automatic closing of the umbrella; wherein said pole is telescopically retractable inside the mast until it abuts on a pin, a locking system of the pole being then operated to immobilize said pole.
