When the umbrella is opened, the first reel 81 rotates to pull down the second open pull cord 42 and wind it back into the first reel 81, and the parachute pull rope 45 is oppositely released from the second reel 82. The case of the umbrella is the opposite of when the umbrella is opened.

In order to realize the opposite winding and releasing operations of the second open umbrella rope 42 and the umbrella pull rope 45, various existing arrangements can be utilized, for example, the driving member 85 passes through a plurality of gear devices, so that the driving member 85 drives the first reel 81 and the second reel 82 to rotate in opposite directions. Alternatively, the orientation in which the second open pull cord 42 and the umbrella pull cord 45 are inserted into the reel is set in the opposite direction, and the scrolling of the first reel 81 and the second reel 82 in the opposite direction can be achieved in the same manner. Alternatively, when the driving member 85 drives one of the first reel 81 and the second reel 82, the other reel is free to rotate, and is driven by the corresponding pulling cord to scroll in the opposite direction.

However, for the above various situations, after the operation of opening and closing the umbrella is completed, the fixing device capable of fixing the umbrella opening state or the umbrella closing state should be provided, which is a prior art and will not be described herein.

In addition, the first reel 81 and the second reel 82 are correspondingly arranged to have different circumferences according to different winding or unwinding lengths of the second open pull cord 42 and the umbrella pull cord 45 at the same time. Round.

Next, the umbrella opening process of the automatic umbrella of the present invention will be described with reference to Figs.

In the open state shown in FIG. 1, the user activates the driving member 85 to rotate the second reel 82 to wind up the recovery umbrella rope 45 (at this time, the first reel 81 is rolled in the opposite direction. The second parachute pull cord 42 is released. The other end of the parachute pull cord 45 pulls down the first rib 13 to gather the rib, and drives the second rib 15 to push the lower nest 30 downward.

As the lower nest 30 moves downward, the first open pull cord 41 connected to the lower nest 30 is taken out to the outside of the upper tube 21 and the middle tube top plug 33 is pulled up together with the middle tube 23, thereby making the middle tube 23 is pulled into the inner cavity of the upper tube 21.

The third open-end drawstring 43 is pulled out of the middle tube 23 as the middle tube 23 enters the inner tube 21, and the lower end of the third open-end pull cord 43 brings the lower tube top plug 32 together with the lower tube 22 The upper tube 22 is pulled up into the inner cavity of the middle tube 23.

As shown in FIG. 4, as the lower tube 22 enters the inner cavity of the middle tube 23, the push rod 25 fixed to the middle tube top plug 33 pushes the movable member 35 downward and away from the lower tube top plug 32, and the second open umbrella pulls The cord 42 will be discharged from the first reel 81.

It can be seen that as the parachute drawstring 45 is wound back to the second reel 82, the upper tube 21, the middle tube 23 and the lower tube 22 will be folded into each other to form an umbrella state as shown in FIG.

When the umbrella is opened, in contrast to the above process, the user activates the driving member 85 to rotate the first reel 81 back to the second open pull cord 42 (at this time, due to the free rotation of the second reel 82 or the driving member 85) Starting in the opposite direction to cause the parachute cord 45 to be released), the second parachute cord 42 pulls the movable member 35 upwardly to the lower tube The top plug 32 pushes the middle tube top plug 33 and the middle tube 23 together so that the lower tube 22 slides out of the inner tube 23 inner cavity.

As the lower tube 22 slides out, the third open cord puller 43 is pulled into the inner chamber 23 and the upper tube 21 is pulled up, so that the middle tube 23 slides out from the inner chamber 21 of the upper tube 21. The first open pull cord 41 enters the inner cavity of the upper tube 21 as the middle tube 23 slides out, and the first open pull cord 41 pulls the lower nest 30 upward.

Due to the rise of the lower nest 30, the second rib 15 extends the first rib 13 upwardly to open the umbrella.

It can be seen from the above process that although the umbrella string has the same function, it not only has the function of opening the umbrella, but also functions to guide the upper tube 21, the middle tube 23 and the lower tube 22 to fold each other when the umbrella is closed.

The above is a description of the structure of the three-fold umbrella and its opening and closing process. When applied to an umbrella of more than four folds, it is only necessary to increase the number of the middle tubes 23 and the number of the third open pull cords 43 so that the number of the middle tubes 23 is the same as the number of the third open pull cords 43, each The connection manner of the third open-end drawstring 43 in the middle tube 23 and the pipe fitting is similarly analogized.
