A user presses down the safety buckle when the runner gets close to positioning pins formed on the center post to allow the hook latches to respectively engage the positioning pins thereby securely fixing the runner in position on the center post.

Abstract: A cushioning device for umbrella includes a first gear, a plate spring, a bolt, and a second gear collectively arranged in a hollow chamber defined between a side cover and a casing. The umbrella has a central post to which an axially-extending toothed rack is mounted. The side cover and the casing of the cushioning device are mounted to the runner of the umbrella to have the second gear mating the rack of the central post. The first gear and the second gear of the cushioning device mate each other. The first gear has a surface to which the plate spring and the bolt are mounted. Rotating the bolt to different extents of tightness makes the plate spring apply different depression forces to the first gear, which changes the frictional resistance between the first gear and the casing.

Abstract: A device that releases an operating collar from an open position on the mast of an opened beach or patio umbrella in the presence of a strong wind, allowing the umbrella canopy to close thereby diminishing the wind force acting on the umbrella. The device includes a locking pin and an associated biasing mechanism. In a working configuration of the device, the pin is exposed for insertion through certain holes in the mast. A distal end of the mechanism faces the mast while a proximal end of the mechanism applies a bias force to a proximal end of the pin. The collar rests on the inserted pin with enough force to overcome the bias force tending to eject the pin. When the collar is urged to rise because of a strong wind acting on the umbrella, the pin ejects thus freeing the collar to move downward as the umbrella canopy closes.

Abstract: An automatic close umbrella is disclosed. As folding an umbrella, the user presses a control device on a handle by one finger so that a tenon is released from a buckle and thus the buckle unit of the lower rib collector is separated from the lower central pole. Furthermore, the lower rib collector descends due to the elasticity of a first elastomer disposed between the upper rib collector and lower rib collector further addition of impacting the hook device of the central pole. Thereby, two central poles are separated from each other and the hook device of each central pole will be released. Therefore, each multi-section central pole is telescopic automatically. Furthermore, as the hinged ribs are folded, the canopy arranged on the hinged ribs will be closed. Thus, as the user enters into a room or a car, the user may close the umbrella easily by only one hand.

Abstract: This specification discloses an automatic opening and closing structure of a collapsible umbrella that allows the user to open the umbrella to use by pressing a button on the handle so that the runner departs from the hook block on the button and moves toward the notch, which further stretches out the umbrella. When pressing again the button, the sliding block on the button moves to push the connected pin within the handle, which further pushes the hook in the lower tube of the shaft out of the opening on the lower tube for storage. The hook then departs from the bullet head provided in the shaft, and the bullet head slides upward by the pulling of a string. By the spring force of the spring connected on the collapsible rib, the umbrella can be collapsed for storage.
