It extends substantially linearly from the upper side of the connecting fitting 9 through the middle bone 7, and is pivotally connected to the locking portion turtle 5b of the connecting fitting 15 via a link 17.

In the middle machine A, the second stage middle rod 2, the third stage middle rod 3 and the fourth
Locking holes la, 2a, 3a are formed at the lower end of the stage middle rod 4 at the upper end of the first stage middle rod 1, second stage middle rod 2, or third stage middle rod 3, respectively, when the middle rod is in an extended state. Elastic repellents 2b, 3b, and 4b are provided which engage in the middle part A.
maintains the extended state.

The sliding potter's wheel 13 is provided so as to be freely movable with respect to a rotary operating tube 18 with an operating knob 18a provided to be movable up and down with respect to the center shaft A. A locking piece 13b is provided on the sliding wheel 13 by a shaft 13a, and the locking piece 13b is attached to the coil spring 1.
3c urges the locking end portion 13d to enter a groove '8b formed in the vertical direction of the potter's wheel operating barrel 18. A locking step portion 18c is formed at the upper part of the groove 18b by a non-notched portion.
is provided. A handle 19 is provided at the lower end of the middle rod A. In the above configuration, in the open state shown in FIG. 1, the operating bridge 18a at the lower end of the potter's wheel operating barrel 18 is locked by the flicker 3c of the third stage middle rod 3, and the sliding wheel 13 is held in place by its locking piece. 13b is engaged with the locking stepped portion 18c to maintain the raised position in the potter's wheel operating barrel 18.

In addition, in the umbrella rib B, the driven protrusion gd of the connecting fitting 9 comes into contact with the lower surface of the main rib 6, and the connecting fitting 15 to the outer rib 8 are attracted by the magnetic wire 16, and the connecting fitting 15 is moved to the elongated hole turtle 5.
c enters into the connecting fitting 10, and the locking part 15b touches the lower surface of the connecting fitting 10, so it cannot rotate, and the umbrella rib B
holds its elongated shape stably as a whole.

To close the umbrella from this state, push in the flicker 3c to pull down the potter's wheel operation tube 18, and while moving the sliding connection 12 above the main rib 6 via the strut 11, keep the umbrella rib B in its extended state. The umbrella is placed in the non-folded and open state as shown in FIG.

At this time, the elastic wire village 14 prevents the umbrella rib B from spreading out. To change from the non-folded umbrella state to the folded umbrella state, use both hands to press the handle 19 and the operating knob 18a of the potter's wheel operating tube 18.
When you pull it by holding it, the repelling 3b of the third stage middle rod 3, which has a weak locking force, automatically retreats and the third stage middle rod 3 enters into the second stage middle rod 2.

When it is pulled further from this state, the potter's wheel operation tube 18t, sliding potter's wheel 13, strut 11 and sliding connector 12 as a whole move downward relative to the birch A and umbrella rib B.At this time, as shown in FIG. As shown in , the elastic wire 14 rotates the connecting fitting 9 to the intermediate rib 7 above the main rib 6 via the driven protrusion gd, and the elastic wire 16 pushes the connecting fitting 15 to the outside of the connecting fitting 10.
