The automatic opening/closing umbrella thus formed is as shown in FIG.
In the state 1 in which the umbrella surface is closed and the inner rod is accommodated, the outer barrel 4 of the inner rod is locked by the outer barrel locking ring 93 and cannot be removed.
2. The bullet-shaped fastener 3 is locked by the bullet-shaped fastener locking ring 96 and cannot be detached.
3. The elastic force of the spiral spring 98 itself causes the rotary disc 97 to automatically wind the closed umbrella rope 72 when the umbrella is closed.
4, the outer cylinder 4 is supported by being stretched by the bullet-shaped fastener releasing member 92 so that the bullet-shaped fastener releasing member 92 and the bullet-shaped fastener locking ring 96 do not come into contact with each other.
5. When the bullet-shaped fastener 3 is locked, the bullet-shaped fastener 3 is urged against the safety lever 99, and the safety lever 99 is disengaged from the turntable 97.

When the umbrella is open 1. When the button 92 is pressed, the outer cylinder locking ring 93 releases the lock to the outer cylinder 4.
2. The open umbrella spring 7 compressed at this time pops out the middle rod and extends the three-stage middle rods (outer cylinder 4, middle cylinder 5, and inner cylinder 6).
3. When the umbrella is closed, the outer cylinder 4 stretches and supports the bullet-shaped fastener releasing member 92, and the bullet-shaped fastener releasing member 92 and the bullet-shaped fastener locking ring 96 do not come into contact with each other. When released, the button 92 does not press against the bullet-shaped fastener locking ring 96, so that the bullet-shaped fastener 3 is also locked.
One end of the opening umbrella rope 71 is fixed to the bullet-shaped fastener 3, the other end is passed through the upper wheel pulley 11, then the lower wheel block 81 is wound, and finally fixed to the upper wheel 1, so that the center rod is extended. At this time, the open umbrella rope 71 is pulled into the center rod, and at this time, the lower wheel 8 comes close to the upper wheel 4 and the umbrella is opened.
4. Since the bullet-shaped fastener 3 is also locked, it is supported by the safety lever 99 in a stretched manner, that is, the turntable 97 is detached. As shown in FIG. 4, after the center rod is jumped out by the opening umbrella spring 7, the closing umbrella rope 72 is pulled out from inside the rotary plate 97 to inside the center rod, and at the same time, the closing umbrella rope 72 also pulls the rotary plate 97. The spiral spring 98 is rotated in the opposite direction to accumulate elastic force in the spring spring 98.

When the umbrella surface is closed 1, since the outer cylinder 4 has already popped out after opening the umbrella, the bullet-shaped fastener releasing member 92 is brought close to the bullet-shaped fastener locking ring 96, and the child-body detaching/releasing member 92 is pushed. The pressure-applying portion is fitted to the bullet-shaped fastener locking ring 96.
2. At this time, after pressing the button 91, the button 91 is pressed against the bullet-shaped fastener releasing member 92, and the bullet-shaped fastener releasing member 92 is also pressed against the bullet-shaped fastener locking ring 96. After the bullet-shaped fastener locking ring 96 is pressed, the bullet-shaped fastener 3 is released, and in this case, the rib 2 is closed by the tensile force of the rib closing spring 21. The lower wheel 8 is also stored toward the hand 9, and the connection method of the opening rope 71 is also such that the bullet-shaped fastener 3 is moved upward and the umbrella surface is closed.
3. As shown in FIG. 5, in order to move the bullet-shaped fastener 3 upward, the tension support to the safety lever 99 is released, and at this time, the elastic force of the tail portion of the safety lever 99 itself rotates the safety lever 99. The rotary plate 97 can rotate only in the direction of the retractable umbrella rope 72 and cannot rotate in the opposite direction due to the locking action of the locking wall 994 with respect to the projection 971 by bringing it closer to the plate 97.
4. When the center rod is manually stored, elastic force is accumulated in the spring spring 98 of the turntable 97. Therefore, when the center rod is manually pushed, the three-stage cylinders come close to each other, the center rod becomes short, and the umbrella is closed. The rope 72 is also wound around the turntable 97.
5. Since the umbrella closing rope 72 is wound around the rotary disc 97, if the compression to the center rod is released, the open umbrella spring 7 has the elastic force of jumping out the three stages of the center rod. Since it is supported by being stretched, the length of the center rod does not hold when it is released without extending the center rod.
As shown in FIG. 6 and FIG. 5, the inner rod continues to be stored until the outer cylinder 4 is locked, and the bullet-shaped fastener 3 is locked, and the umbrella surface is closed to accommodate the inner rod.
