[Technical field to which the invention belongs]

 The present invention relates to an automatic umbrella opening / closing control structure.

[0002]

[Prior art]

 A US application corresponding to Taiwan Patent No. 392448, “Automatic Folding Umbrella with Simplified Control Mechanism and Reduced Parts,” published on June 1, 2000, is disclosed as US Pat. No. 5,992,433.

[0003]

[Problems to be solved by the invention]

 However, while the control mechanism described above has been simplified and reduced in parts, it is still very complex in practice. Therefore, a main object of the present invention is to provide a double-barreled automatic umbrella opening / closing control structure which can be controlled by a new design even if the two-stage umbrella opening / closing control is accidentally touched.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, a double-branch automatic umbrella opening / closing control structure according to the present invention mainly passes an umbrella bone having an umbrella closing control seat through an umbrella closing control set. Further, after the handle is inserted into the center rod sleeve, the pin is inserted into the lower pipe and the umbrella closing control seat inside the lower pipe to be securely connected. When the umbrella closing control seat is in the closed state, the trigger is lowered by pushing down the lower nest, and the pushing convex body on the inner wall of the button is displaced. When the button is first pressed, the annulus retreats from the incision in the lower nest and the lower nest is released. With the opening of the umbrella, the trigger of the umbrella closing control set is raised by the spring at the lower end of the umbrella until it is aligned with the push-button body. When the button is pressed again, the pushing convex on the upper inner wall pushes the trigger of the umbrella closing control set. The sprung head of the connecting arrowhead hung on the side hole of the umbrella-closed control seat by the control spring is pushed into the hole of the arrowhead and detached from the tensioned drawstring. The lower nest lifted by the drawstring loses its lifting support force, and the umbrella closing spring contracts the entire umbrella bone, pushing the lower nest downward and the umbrella closes.
