JPS6029482B2 - One-handed automatic handle opening/closing umbrella - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a western umbrella that can be automatically opened and closed by operating the handle with one hand.

Conventionally, Western umbrellas that can open and close automatically have not been popularized because of their complicated structure, which makes it difficult to commercialize them because they are expensive, heavy, and unsightly.Also, even if they were commercialized, only the current one It seems that they will not be as popular as Western umbrellas. The present invention aims to improve the above-mentioned difficulties by simplifying the structure to a greater degree than the conventional one, and thus to provide a one-handed automatic handle opening/closing umbrella that is lightweight, inexpensive, easy to operate, and widely used. Next, an example will be described. 1st
In the figure, reference numeral 1 denotes a handle tube which is the center of the umbrella, and a handle 3 having a main rib 2 pivotally attached thereto is fixed to its upper part, and a handle 4 is fixed to its lower part.

In addition, the handle tube 1 at the bottom of the fixed Ugurukuru 3 has a locking hole IA,
In addition to the guide groove IB and the guide long groove IC, the handle tube 1 above the fixed handle 4 is also provided with a guide groove ID and a guide long groove IE, respectively. One end of the support bone 5 is pivotally connected to the main bone 2, and the other end of the support bone 5 is pivotally connected to a descending member 6 that is movable up and down along the handle tube 1. Going down again 6
is provided with a locking hole 6A. Therefore, the descending member 6 is a pipe body having an inner diameter slightly larger than the outer diameter of the handle pipe 1.
It is reinforced so that it can be raised and lowered along the outer periphery. and handle tube 1
A tube body 7 having an inner diameter somewhat larger than the outer diameter is fixed to the middle part of the stem tube 1, and a closing spring 8 is installed between the tube body 7 and the lower part 6. On the other hand, the handle pipe 1 is loaded with an operating member 10 which allows the stone protrusion 9 always protruding from the upwardly moving part 3 to be raised and lowered. A tube body 11 having an outer diameter is fixed to the lower part of the operating punch 10 and has an outer diameter slightly larger than the inner diameter of the handle tube 1. Attach the spring 12. Therefore, the opening guide 12 installed between the actuating village 10 and the tube body 11 is both inserted into the handle tube 1. In addition, in the operation village 10 there is an auxiliary spring 14 that assists the operation of an umbrella opening pawl 13 that is removably engaged for opening the umbrella, and an umbrella closing pawl 15 that is releasably engaged for closing the umbrella. An auxiliary spring 16 is attached to each. Therefore, opening claw 1
3 is removably locked in a locking hole IA provided in the handle tube 1, and the closing claw 15 protrudes from the outer diameter of the handle tube 1 and is removably locked in a locking hole 6A provided in the lower part 6. It is configured to be locked to.
In order to stop the umbrella claw 15 at a fixed location, a pin 17 is inserted into the operating village 10 above the umbrella claw 15 so as to protrude longer than the outer diameter of the handle tube 1. On the other hand, the opening claw 13 and the operating protrusion 18 are attached together with a connecting member 19, and the closing claw 15 and the operating protrusion 20 are attached together with connecting members 21 and 22. The base is constructed so that only the handle 4 is always stopped near the handle 4. In addition, the Shuto ball retaining ring 23 holds the main frame 2 together. Next, the operation will be explained.

Closed umbrella → Seki umbrella When the umbrella is closed, it is in the state shown in FIG.

The stone protrusion 9 is at the uppermost position, and the pin 16 is at the uppermost position of the guide groove IB provided in the handle tube 1. Also, Seki Umbrella Claw 13 and Closing Umbrella Claw 1
5 is in a state where each is off. In this state, when the handle 4 is grasped with one hand and the stone protrusion 9 is pressed against the ground, etc., the operating pestle 10 moves toward the handle 4 as shown in FIG. 3, compressing the opening spring 12 and 13 is locked in the locking hole IA of the handle tube 1 to be in the energized state, and the operating protrusion 18 moves and stops near the handle 4. Also, since the operating punch 10 has moved, the closing claw 1
5 is locked in the locking hole 6A of the lower part 6. However, since the two operating protrusions only work from opening to closing the umbrella, it does not move and is stopped from the beginning. Then, by grasping the handle 4 with one hand and pulling the operating protrusion 18 with the tip of a finger, the canopy claw 13 is removed from the locking hole IA, the compressed opening spring 12 is released, and the operating punch 10 is pushed up and lowered. Since the umbrella claw 15 is locked, the umbrella 6 moves upward and upward in three directions, and the support bone 5 applies an opening force to the main bone 2, thereby closing the umbrella. Also, operation protrusion 1
8 also moves up and down in three directions. Therefore, the umbrella closing spring 8 is stretched until the umbrella is fully closed, but the elasticity of this spring is smaller than the elasticity of the opening spring 12 in the compressed state. However, the elasticity after the umbrella opening claw 15 of the umbrella opening spring 8 is released from the locking hole 6A, which is in the stretched state when the umbrella is fully opened, is the same as that of the umbrella in the released state, that is, the elasticity is zero. Naturally, the elasticity is greater than the elasticity of the spring 12. Seki Umbrella -> By grasping the opening handle 4 with one hand and pulling the operating protrusion 20 with the fingertip, the lock between the closing claw 15 and the locking hole 6A is released.

As mentioned above, the elasticity of the umbrella opening spring 8 in the stretched state is greater than the elasticity of the umbrella opening mirror 12 in the released state, so the lower arm 6 with the umbrella closing spring 8 attached moves toward the hand. , a closing force is applied from the support bone 5 to the main bone 2, so that the umbrella is closed. Furthermore, when the umbrella cloth is opened, it is pulled tightly and the main ribs 2 are also deflected, creating tension, so when the umbrella closing claw 15 is released from the locking hole 6A, the tension also causes the umbrella to close. Since it becomes a supporting force, the elasticity of the umbrella opening spring 8 can be reduced. When the umbrella closing is completed, as shown in FIG. 2 again, the stone protrusion 9 is at the uppermost position, the pin 17 is at the uppermost position of the guide groove IB provided in the handle tube 1, and the umbrella claw 13 and the closing claw 15 are also located at the uppermost position. If each umbrella comes off, there will be no energy for the next umbrella, so as mentioned above, hold the handle 4 with one hand and press the stone protrusion 9 against the ground to compress the spring 12 for the umbrella. Produces energy for Sekigasa. Furthermore, since the closing pawl 13 and the closing pawl 15 are attached to the operating punch 10 by applying the principle of a mallet, they can be removed by pulling the operating protrusion with a light force. The present invention differs from the automatic opening/closing Western umbrella in which the stone protrusion of the follower is fixed, as mentioned above, the umbrella claw is detachably engaged for the guide umbrella, and the umbrella is detachable for the closing umbrella. A closing claw for locking is attached to an operating member that can be moved up and down inside the handle tube, a spring for the porridge umbrella and an operating pestle are placed inside the handle tube, and a closing spring is installed outside the handle tube. The structure is such that the spring for the umbrella is compressed by the push-in operation, applying force to the main frame of the umbrella, and at the same time the spring for closing the umbrella can store energy. When pressed, the opening claw locks on the handle tube and the closing claw locks on the lower part, and from this state, the umbrella can be opened and closed by pulling each operating protrusion at hand with your fingertips. In addition, even if you accidentally pull the operating protrusion for closing the umbrella when opening the umbrella, it will not have any effect on the opening claw and the opening claw. Since there is only the operating protrusion for the umbrella, it is constructed so that there is no chance of accidentally pulling the operating protrusion for the umbrella.

Therefore, it is possible to provide a one-handed automatic handle opening/closing umbrella that is simpler in structure, lighter in weight, easier to operate, and less expensive than conventional automatic opening/closing umbrellas.
