The lower end of the member (5) is fixed to the upper end of the hand (2). Two or more wall holes (6) are provided on the peripheral wall of the intermediate cylindrical member (5) at a position equidistant from the upper end surface of the hand (2), and each wall hole (6) has A small ball (7) having a diameter larger than the thickness of the peripheral wall of the intermediate cylindrical member (5) is located, and when the small ball (7) is pressed from the inside or outside, the small ball (7) Part of the spherical surface of the inner cylindrical member (5) protrudes inward from the inner peripheral wall or outward from the outer peripheral wall. The wall hole (6) and the small ball (7) may be provided at two positions opposite to each other with the middle rod (3) interposed therebetween, as shown in Figs. 1 and 2; It is preferable to provide three to eight places on the peripheral wall so as to be even. Further, a large cylinder operating member (10) concentric with the middle rod (3) is provided outside the middle cylindrical member (5) via a large diameter coil spring (U) fixed to the upper end of the hand (2). The large cylindrical operating member (10) has two inner peripheral walls (12a, 12b) having different inner diameters as shown in FIGS. The inner diameter of the first inner peripheral wall (12a) located on the side is smaller than the inner diameter of the second inner peripheral wall (12b) located on the upper side. According to the present invention, when the mouth closure (1) is locked, the step located at the boundary between the two inner peripheral walls (12a, 12b) of the large cylinder operating member (10) is positioned at the upper end of the middle cylindrical member (5). Generally, it is structured to be locked to an annular projection provided on the horn (see Fig. 1).

In addition, a locking projection (4) is formed at the lower end side of the mouthpiece (1) of the automatic umbrella of the present invention, and as shown in FIG. 2) When the locking projection (4) of the mouth lip (1) is positioned below the small ball (7) by pushing it down to the side, the small cylindrical member (8) is pushed down, but the large cylindrical operation is performed. The member (10) is pushed up by the large-diameter coil spring (11), and the small ball (7) moves inward by coming into contact with the first peripheral wall (12a) of the large cylindrical operating member (10), Part of the small spherical surface of the small ball (7) protrudes inward from the inner peripheral wall of the middle cylindrical member (5). The protruding small ball (7) locks the locking projection (4) of the mouth-cloth (1), the mouth-closing (1) is fixed to the upper end of the hand (2), and the umbrella is closed. State.

On the other hand, when the large cylindrical operating member (10) in the state of being pushed up as shown in Fig. 1 is pushed down to the side of the hand (2), the first inner peripheral wall (7) at the height of the small ball (7) 12a) moves downward, and is located at the height of the second inner peripheral wall (12b) having a larger inner diameter than the first inner peripheral wall (12a) and the sphere (7) (see FIG. 2). The small ball (7) is moved outward by the part (4), and the locking of the locking projection (4) is released. The mouthpiece クロ) thus opened is pushed up by the action of the small-diameter coil spring (9) provided below the small cylindrical member (8), and the ribs are automatically opened. At this time, the step located at the boundary between the two inner peripheral walls (12a, 12b) of the large cylinder operating member (10) is caused by the small ball (7) moving outward as shown in FIG. The operation member (10) is locked, and is fixed in a depressed state.

The locking projection (4) of the mouth lip (1) in the present invention has a squared portion in contact with the small ball (7) so that the mouth lip (1) can be securely engaged. 1), and the locking projections (4) are spaced vertically in two steps at the lower end of the mouth lip (1), that is, above the locking projections (4) shown in the figure. In this case, a small ball (7) is formed by two locking projections (4) when the mouth closure (1) is pressed down. Is housed in a space.

Thus, in the automatic opening umbrella of the present invention, like a conventional umbrella, a slit-shaped Since there are no holes, the center rod has sufficient strength and the center rod is unlikely to bend or break. Further, since the umbrella of the present invention does not have a structure in which a cisser is inserted into a slit hole of a mouth lip and a mouth lip is fixed as in the case of a conventional umbrella, the position of the slit hole and the cissing are shifted and the umbrella is shifted. It is not impossible to open and close. Furthermore, the present invention not only solves the problem of the strength of the middle rod in the conventional automatic umbrella, but also makes it difficult to form a slit hole, so that a material that has not been suitable as an automatic umbrella before, such as wood And plastic can also be used.

In the present invention, except for the coil springs (9) and (11) made of metal, the material of the receiving member of the blinds shown in FIGS. 1 and 2 is not particularly limited.

In the automatic umbrella of the present invention, the above-described structure provided on the upper end side of the hand (2) may be provided integrally with the hand (2), or may be provided separately from the hand (2). May be provided by attaching a component or device having the following to the upper end of the hand (2):

In the case of the automatic opening umbrella of the present invention, the mouth lip can be securely locked by pulling the mouth lip toward the hand side and pushing it into the middle cylindrical member, and furthermore, by merely pushing down the large cylindrical operation member, the engagement of the mouth lip is achieved. This is very convenient because the lock is released and the ribs can be opened automatically. In particular, in the automatic umbrella of the present invention, unlike a conventional so-called jump umbrella, the umbrella is opened by pressing any part of the circumference of the large cylindrical operating member, instead of pressing an operation button at a specific position. The advantage is that the finger can be used with a soft foot.

Furthermore, since there is no slit hole provided in the center rod as in a conventional umbrella, the center rod has sufficient strength, and has the advantage that the center rod is unlikely to bend or break. Yes, and there is no need to provide repelling holes in the mouth lip.
