Further, one end of the tow rope 30 is connected to the pulley base 80, the other end is wound around the second pulley and the first pulley 81 in this order, and is connected to the hook head 20 located in the middle rod 10. Further, it further includes the hand button structure of the umbrella in the present invention described above. The lower end of the middle rod 10 is inserted into the pressing base 2. Further, the middle rod 10 is provided with an elastic portion hole to be combined with the elastic portion 34.

In the present embodiment, the present invention further includes a safety cable 40. One end of the safety rope 40 is connected to the ratchet 81, and the other end is connected to the pulley base 80. Moreover, the safety rope 40 penetrates the hook head 20.

In this embodiment, the middle rod 10 includes an outer pipe 101, a middle pipe 102, and an inner pipe 103 that are slidably fitted in this order from the top. The upper wheel 60 and the pulley base 80 are installed at the upper end of the outer pipe 101. Further, the lower wheel 70 is slidably installed on the outer tube 101, and the lower end of the inner tube 103 is inserted into the pressing base 2. The hole of the elastic portion 34 is provided at the bottom position of the outer pipe 101. A hollow connecting rod 100 for moving the hook head 20 downward is connected to the bottom end of the pulley base 80. The hook head 20 is located below the connecting rod 100, and the safety rope 40 and the towing rope 30 each penetrate the connecting rod 100. The umbrella opening spring 90 is used to relatively extend the outer pipe 101, the middle pipe 102, and the inner pipe 103. The umbrella opening spring 90 is covered on the outside of the hollow connecting rod 100, and the upper end is in contact with the upper wheel 60 and the bottom end is in contact with the holding pipe 9.

The umbrella collecting state (preparing to open the umbrella) of the automatic opening / closing umbrella of the present invention is shown in FIGS. 6, 2, and 4. At this time, since the elastic portion hole of the outer pipe 101 is locked to the elastic portion 34, the middle rod 10 cannot be extended. Further, the hook head 20 is regulated by the position regulating portion 611 of the second movable member 6. When the button 3 is pressed, the button 3 moves the elastic portion 34 so that the elastic portion 34 is separated from the elastic portion hole of the outer tube 101, and the umbrella opening spring 90 releases energy. As a result, as shown in FIG. 7, the outer pipe 101 and the middle pipe 102 of the middle rod 10 move upward. As the outer tube 101 and the inner tube 102 move upward, the hook head 20 is locked to the position restricting portion 611 of the second movable member 6, so that the lower wheel moves upward by the tow rope 30. As a result, the umbrella bone frame 50 completes the umbrella opening operation. Further, as shown in FIG. 4, the safety rope 40 is pulled. When the outer tube 101 and the inner tube 102 release the slide base 4, the slide base 4 moves the first movable member 5 upward under the action of the second elastic member 33. As a result, the first movable member 5 enters the pressing range of the button 3, and as a result, the umbrella collection ready state is completed. Then, when the button 3 is pressed again, the first movable member 5 is pressed and the second movable member 6 is moved in the pressing direction, so that the position regulating portion 611 of the second movable member 6 is moved as shown in FIG. Release the hook head 20. As a result, the umbrella bone frame 50 of the automatic opening / closing umbrella realizes the closing of the umbrella as shown in FIG. 8 by the action of the umbrella spring 501. Further, as the hook head 20 moves upward, the hook head 20 releases the pawl 83, so that the pawl 83 engages with the ratchet 81 under the action of the fourth elastic member 84, as shown in FIG. To do. At this time, the ratchet 81 can only rotate in the forward direction, and cannot rotate in the reverse direction. Therefore, when the middle rod 10 is compressed, the ratchet 81 rotates forward due to the action of the mainspring 82, and the safety rope 40 can be recovered. Further, when the center rod 10 is released in the compression process, the safety rope 40 is pulled, but the ratchet 81 cannot rotate in the opposite direction because it is braked by the pawl 83. As a result, the center rod 10 does not elastically return and extend due to the pulling action of the safety rope 40.

At the time of collecting the umbrella, when the middle bar 10 is compressed, the middle bar 10 is gradually shortened. Further, the hook head 20 enters the holding pipe 9 and moves downward until it is pushed by the connecting rod 100 and locked in the position regulating portion 611 of the second movable member 6. Further, when the hook head 20 pushes the pawl 83, the pawl 83 is released from the ratchet 81. Then, the ratchet 81 recovers the safety rope 40 by the action of the mainspring 82, and the safety rope can be released when the umbrella opening function is realized in the present invention.

The parts not mentioned in the automatic opening / closing umbrella of the present invention are the same as those in the prior art, or can be realized by using the prior art.

The above-mentioned embodiment is merely for further explaining the hand button structure of the umbrella and the automatic opening / closing umbrella in the present invention, and the present invention is not limited to the embodiment.
