Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention accumulates elastic force by pressing the tip of an umbrella against the ground or a wall surface to compress a coil spring provided inside the umbrella shaft, and by operating a button. The present invention relates to an automatic umbrella that can be opened and closed by releasing the elastic force stored in a coil spring.

[0002]

2. Description of the Related Art For example, a conventional automatic opening / closing umbrella has a prior art disclosed in Japanese Patent No. 1439641 filed by the same applicant. Such an automatic opening / closing umbrella is provided in the intermediate cylindrical shaft, and has a strong first coil that always urges the upper and lower inner shafts outside both ends of the intermediate cylindrical shaft, that is, in directions away from each other. A spring and a second coil spring that is provided on the outer periphery of the upper end of the intermediate tubular shaft and that biases the intermediate sliding ring (wheel) and the lower sliding ring (wheel) in a direction away from each other when the umbrella is opened, The handle portion is provided with a push button device that operates a locking spring piece that can be engaged with and disengaged from the intermediate cylindrical shaft and the outer cylindrical shaft.

In this automatic opening / closing umbrella, the first coil spring is compressed by pressing the handle with the tip of the umbrella closed to the ground or wall while the umbrella is closed to store elastic energy for opening / closing the umbrella. When the push button is pressed to release the locked state between the locking spring piece and the outer cylindrical shaft, the outer cylindrical shaft is partially elastically released from the first coil spring (energy) to cause the intermediate cylindrical shaft to move. At the same time as it slides up to the upper end and opens the umbrella through the umbrella frame, the lower wheel and wheel provided on the outer cylindrical shaft is the second
The coil spring is compressed to store the elastic force for closing the umbrella. When the button is pressed again with the umbrella open, the locking state between the locking spring piece and the intermediate cylindrical shaft is released, and the intermediate cylindrical shaft rises due to the elastic force of the second coil spring, and the upper and lower parts The inner shaft slides up and down on the intermediate cylindrical shaft by the elastic force of the first coil spring, and closes the umbrella through the canopy.

[0004]

In the above-mentioned conventional example, when the umbrella is opened and closed, the first coil spring and the second coil spring act in directions opposite to each other, that is, in directions repelling each other. Part of the resilience of the coil is consumed by the other coil spring, and a coil spring having a sufficiently strong resilience must be used. Therefore, when using
When holding the handle and pressing the umbrella with the tip of the umbrella protruding to the ground, the first coil spring is compressed to store elastic energy used as power for opening and closing the umbrella.
An extremely large pressing force of kg to 20 kg is required, and it is generally necessary to apply a part of the body weight in addition to the arm force, that is, a force applied to the arm by tilting the body toward the arm. Therefore, it is difficult for even an adult to fully push the umbrella with one hand while sitting on the seat of a train or a bus until the first coil spring is completely compressed.
Moreover, since children and old people can hardly push the umbrella even when standing, it is inconvenient to use, the age group of users is limited, and it is not an automatic umbrella that anyone can use easily regardless of age or sex. There are challenges.

In the automatic opening / closing umbrella constructed as described above, when the umbrella is closed, the upper coil spring 415 has the wire rod 54 in which the movable plug 414 is pushed upward by the raising of the drill bit 22 by the closing operation. , 55, the upper end of the spring 415 is compressed upward, so that the energy for opening the umbrella is maintained in a compressed state. On the other hand, the umbrella closing coil spring 8 is in a free state,
Coil spring 42 provided between movable barrel 421 and lower wheel 23
2 is also free. At the same time, the upper bail 232 is locked in the locking hole 11 of the umbrella shaft 1 and the lower bail 72 is locked in the locking holes 322, 612 of the center shaft 32 and the elastic actuating piece 61 which overlap with each other to maintain the closed umbrella state. ing.

When using an umbrella, first, the umbrella handle 3 is grasped and the umbrella tip 9 is pressed in a state of being projected on the ground or the wall surface, or the umbrella handle 3 and the umbrella tip 9 are grasped by both hands and compressed in opposition. Then, the tip of the center shaft 32 slides in the umbrella shaft 1 while compressing the coil spring 8 for closing the umbrella by the relative motion between the umbrella handle 3 and the umbrella shaft 1, while the lower end of the umbrella shaft 1 also moves by the relative motion. It slides down into the extension cylinder portion 711 of the cylinder 71, and finally the lower repellent 72 of the operating means 7 is locked in the locking hole 12 below the umbrella shaft 1, and energy for closing the umbrella is stored in the coil spring 8. At the same time, the movable cylinder 4
21 is a wire rod 52, and the lower end is a center shaft plug 32.
Since the wire rod 53 is pushed upward by 4 and is hung up in an interlocking relationship with the wire rod 53, the coil spring 422 is stretched and energy can be stored.

To open the umbrella, the operation button 73 may be pushed upward with the thumb. At this time, the push-up rod 78 rises with the movement of the operation button 73, and the movable plug 326 is moved upward at the lower end of the rod 78.
The moving distance is restricted by the relationship between the pin 321 and the long hole 325. Then, the operating wire rod 62 whose lower end is fixed to the movable plug 326 pushes up the sliding block 60 at the bent portion 621 and pushes the repellant 232 away, so that the repellant 23
2 and the locking state of the locking hole 11 of the umbrella shaft 1 are released, and the upper and lower storage mechanisms 41, 42 for opening the energy storage means 4 for opening the umbrella.
The stored energy, that is, the spring elastic force, is released. Accordingly, the lower wheel 23 is moved upward by the contracting force of the spring 422, and at the same time, the inner wheel 22 is moved by the spring 415.
The extension force moves to the lower side via the wire rods 54 and 55, and the umbrella can be opened in an interlocking relationship with the respective lathes 21, 22 and 23 of the umbrella frame 2. At this time, the upper and lower ends of the spring stopper 76 are located at the upper ends of the guide grooves 714, 715, respectively, and the upper end receives the lower end of the umbrella shaft 1. Therefore, even if the umbrella receives a strong wind, it is automatically closed. There is no. On the other hand, in the heart cam device 75, the heart cam 751 is operated by the operation button 73.
The head of the driven arm 752 is guided by the cam groove 753 to come under the cam 751 and can be used to operate the operation button 73 for closing the umbrella.

Next, when the opened umbrella is closed, the operation button 73 may be pushed downward. At this time, the slider 731 of the operation button 73 pushes down the rear end of the lower repelling 72 to release the locked state between the front end locking end of the lower repelling 72 and the locking hole 11 of the umbrella shaft 1. The umbrella closing coil spring 8 in the compressed state expands, releases the umbrella closing energy, and moves the umbrella shaft 1 so as to extend upward. At this time, the lower wheel 23 moves downward with respect to the ascending umbrella shaft 1, and the upper repellent 232 finally stops by stopping in the locking hole of the umbrella shaft 1, and at the same time, the inner wheel 22 also moves through the interlocking means 5. It moves until it contacts the lower surface of the upper wheel 21, and the energy storage mechanism 41 for opening the upper umbrella uses the inertia when the umbrella frame 2 returns to the closed state by the wheel mechanism 21, 22, 23 via the interlocking means 5. Is compressed and stores energy, and the umbrella closes and returns to its original closed state.

[0022]

According to the present invention configured as described above, the energy storage means 4 for opening an umbrella operates in two steps, upper and lower, and the storage means 41 for opening an upper umbrella is operated when the umbrella is closed or Since energy is stored in advance during assembly,
When the energy for closing the umbrella is stored by compressing the coil spring for closing the umbrella 8, there is no need to resist the elastic force of the coil spring for opening 415 as in the conventional case, so that unnecessary energy is not consumed. Since the coil spring 8 for closing the umbrella can be compressed independently, a coil spring having a light spring force can be used, and the pressing force is about 1/2 or less of that of the conventional one, that is, 7 to 10 k.
It can be operated with g force. In addition, the upper and lower opening umbrella energy storage mechanisms 41 and 42 lift springs 415 and 422 by lever rods 51 to 55 having a lever action, instead of the conventional method of directly compressing a coil spring to store energy. By using the method of storing energy, that is, the method of operating in the opposite manner, the spring can be operated with a light force. Further, the operation button 73 of the operation means 7 is guided by the heart cam device 75 so that the opening / closing operation sequence or the operation of pushing up / down can be reliably performed. Further, since the operation means 7 is provided with the spring stopper 76, it is possible to prevent accidental closing when an external force or a strong wind is received.
