The force enables the lowering of the lower wheel 3 to the closed position in FIG. 4 automatically. The umbrella closing implement 5 descends to a position regulated by the lower end edge of the window hole 1b, and the pushing-down action body 5a is at a position lower than the upper wheel cylinder portion 2a by a certain amount as shown in FIG. When the lower locker 3 is pushed up to the same position when the umbrella is opened next time, the lower locker 3 is pushed up by the upper surface of the lower locker 3 and is lifted, whereby the entire umbrella closing operation tool 5 is lifted. When the lower locker 3 is grasped and the umbrella is directly pulled down to close the umbrella, the umbrella closing operation tool 5 descends by its own weight.

5 and 6 show a second embodiment in which the present invention is implemented in a topless folding western umbrella having the structure disclosed in Japanese Utility Model Publication No. 63-37858. As is customary in Topless-type folded western umbrellas, only one set of umbrella-bone mechanisms is shown, and the other end of the skeleton 11 pivotally supported at one end by the upper wheel 2 is placed in the middle of the skeleton 7. In addition, one end of the rib 7 pivotally supported by the lower rocker 3 is pivoted in the middle of the rib 6, and both ends are pivoted in the middle of the rib 6 and the midpoint of the backbone 11. The supporting ribs 12 are provided so that each of the above-mentioned umbrella frames can be automatically opened / closed and rotated by the vertical movement of the lower wheel 3 on the umbrella handle 1. The umbrella handle 1 is made up of a relatively small and large diameter upper handle 1A and a lower handle 1B that are elastically fitted together. The upper wheel 2 is at the upper end of the upper handle 1A, and the hand 4 is at the lower end of the lower handle 1B. They are stuck to each other.

As shown in FIG. 5, the position where the lower wheel 3 contacts the upper wheel cylindrical portion 2a is the open umbrella position of the lower wheel 3, and the upper position is in the extended state as shown by the chain line in FIG. It is said that when the lower wheel 3 is pulled down to the boundary between the handle 1A and the lower handle 1B, the closed umbrella state is obtained.

On the other hand, the ball stopper 22 is connected to the lower end portion of the umbrella closing operation tool 5 by a lateral pin 28 which is inserted through the window hole 1b of the umbrella handle 1 as described above.

The cylinder 21 that engages the lower roller 3 in the open position at the position shown by the chain line shows the lower roller 3 when the closing operation tool 5 is pulled down. Push it down. That is, in this embodiment, the cylindrical body 21 is configured as the pushing-down acting body as described above. Also, the ball clasp 22 lowers the umbrella closing operation tool 5 inside the umbrella handle 1 when it is pulled down by the finger of the hand holding the hand 4, and is configured as a pulling down operation body as described above. The operation of the third embodiment is substantially the same as that described above for the first embodiment.

FIG. 8 shows a fourth embodiment in which a spring 23 for raising the umbrella closing operation tool 5 together with the tubular body 21 and the ball clasp 22 is added to the structure of the third embodiment shown in FIG. , Showing. The spring 23 is a weak coil spring, and the pin 26 for fixing the hand 4 receives the lower end thereof, and the upper end thereof acts on the lower end of the umbrella closing operation tool 5. Therefore, according to the present embodiment, the cylinder 21 is raised to the position where it comes into contact with the upper wheel 2 in the closed umbrella state shown in the figure, and when the umbrella is opened from this state, the lower roller 3 is in the maximum raised position. 21 is contacted and the opening position is restricted. FIG. 8 exemplifies a ball clasping state by the ball clasp 22 for one main rib 6.

When the structure for forming the umbrella closing operation tool 5 from the pipe material as in the embodiment of FIGS. 7 and 8 is applied to the folding western umbrella as shown in FIGS. A pipe material such as a three-piece pipe or three pipes may be fitted so as to be expandable and contractable, and the pull-down operation of the lower wheel may be obtained in the most extended state.

It should be noted that the present invention can be implemented even in a western umbrella provided with a spring that functions similarly to the spring 8 described above, which is different from the western umbrellas according to the above-described embodiments in a structure that does not directly act on the lower wheel. Needless to say.
