DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, the present invention is roughly classified into a shank 1, an umbrella opening spring 2, a cylinder 3, an umbrella closing spring 4, an upper claw 5, a lower claw 6, a canopy structure 7, a wire 8,
It consists of a handle 9 and the like.

The shank 1 comprises an inner pipe 11 and an outer pipe 12 which can slide on each other. An intermediate ring 13 is fixed to the upper portion of the inner pipe 11. Extension 14, the intermediate ring 13
Is formed to extend over. A lower ring 15 is movably provided on the outer tube 12 so as to slide on the outer tube 12. Both inner and outer tubes 11 and 12 are provided with upper holes 16 and 17 and lower holes 18 and 19, respectively. In the preparation state shown in FIG. 2, the inner pipe 11 is located below the outer pipe 12, and the upper holes 16 and 17 and the lower holes 18 and 19 are aligned with each other.

The umbrella opening spring 2 is an extension 1 of the inner pipe 11.
It is supported within 4 to telescopically expand and contract. The extension 14 is enclosed in the cylinder 3. The cylinder 3 slides with respect to the extension 14 by the telescopic action of the opening spring 2. The lower end of the upper ring 31 is fixed to the lower end of the cylinder 3.

The umbrella closing spring 4 is the intermediate ring 13 described above.
And the outer tube 12 is provided in a microscopic state in a limited state between the top ends thereof. The outer tube 12 is slidable with respect to the inner tube 11 by the telescopic action of the closing spring 4. The upper and lower claws 5 and 6 form a lock mechanism. The lower claw 6 has a hair spring 61 at the lower end of the inner tube 11.
The upper claws 5 are also supported by the same hairspring 51 to be repelled in a container 52, which is also slidable in the inner tube 11. Of course, the container 52 is provided with a slit through which the hook portion of the upper claw 5 projects.

A wire 8 connects between the upper claw 5 and the lower ring 15. The outer tube 12 has a longitudinal slot 20 below the ring 15 below it, while the inner tube 11 also has a longitudinal slot 21 in the corresponding middle part. The wire 8 passes through its juxtaposed slots 20, 21 at its upper end and then snaps into engagement with the lower ring 15. The wire 8 has rigidity so that the upper claw 5 can be pushed and pulled.

Since the canopy structure 7 is exactly the same as a normal one, detailed description thereof is unnecessary and will be omitted here. Only the upper, middle and lower rib structures are pivotally attached to the upper, middle and lower rings 31, 13 and 15, respectively. The handle 9 is provided at the lower end of the shank 1. Handle 9
The inner actuating body 91 is provided with two raised portions 92 and 93, which face the holes 17 and 19 above and below the outer tube 12, respectively. Further, the lower ring 15 includes the inner and outer pipes 11 and 12
A lock body 22 is provided in parallel to lock the lock holes 23 and 24 of the above, thereby supporting the lower ring 15 more stably and preventing the canopy structure 7 from sliding out accidentally.

Next, the operation of this device will be described. The user needs a preparatory action before opening the umbrella. For example, the handle 9 is held with one hand and the end of the cylinder 3 is placed on the ground, the back surface of the wall, or the other hand. When a slight force is applied by one hand, the outer tube 12 moves with respect to the inner tube 11 and compresses the umbrella closing spring 4. Since the umbrella opening spring 2 is held in the compressed state when the umbrella is closed, only the umbrella closing spring 4 is easily compressed with a slight force in this preparatory operation. The handle 9 held by the outer pipe 12 moves upward with respect to the inner pipe 11 and pushes the lock body 22 of the lower ring 15 out through the corresponding lock holes 23, 24 so that the upper and lower holes 17, 19 are Move them to positions aligned with the upper and lower holes 16 and 18, respectively.

At this point, as shown in FIG. 2, the upper claw 5 is pushed downward by the wire 8 and locked in the aligned holes 16 and 17, and the umbrella opening spring 2 is locked in a compressed state and restricted. To do. On the other hand, the lower claw 6 simultaneously moves downwards with respect to the outer tube 12 by the inner tube 11 and is locked in the aligned holes 18 and 19 to lock and limit the umbrella closing spring 4 in the compressed state.

In this ready state, the umbrella can be opened at any time. For example, when pushing the upper side of the operating body 91 with the thumb of the hand holding the handle 9, the upper claw 5 is disengaged from the holes 16 and 17 arranged by the umbrella opening actuating portion 92, and the umbrella opening spring 2
The locked state of is released. As a result, the umbrella opening spring 2 expands due to the energy stored during compression, the cylinder 3 moves upward with respect to the extension 14 of the inner tube 11, and the canopy structure 7 opens. At the same time lower ring 1
5 moves upward to the upper end of the outer tube 12, the lock body 22 is locked in the lock holes 23 and 24 arranged side by side, and the upper claw 5
Is pulled upwards by the wire 8. At this time, as shown in FIG. 3, the lower claw 6 is held in the locked state.

When closing the umbrella, the user only has to press the lower side of the actuating body 91, whereby the lower claw 6 is pushed by the umbrella closing actuating portion 93 and the hole 19 under the outer tube 12 is pushed.
And the umbrella closing spring 4 in the locked state is released. This causes the umbrella closing spring 4 to expand due to the energy stored during compression, the outer tube 12 moves downward relative to the inner tube, and the canopy structure 7 closes. At the same time, the umbrella opening spring 2 is compressed, and the lower claw 6 is moved upward by a certain distance by the inner tube 11 to return to the state shown in FIG.

[0016]

As described above, the arrangement and configuration of the automatic umbrella according to the present invention is remarkably simplified, but the structure is sufficiently strong and stable. Furthermore, the operation is easy and reliable, and the manufacturing cost is greatly reduced. Although the present invention has been described in detail by the preferred embodiments, many changes, modifications and variations can be made within the scope of the present invention without departing from the spirit thereof.
