[Industrial applications]

 The present invention relates to a one-handed openable umbrella that can be opened and closed with only one hand.

[0002]

[Prior Art]

 FIG. 5 is a conventional example of this type of umbrella, which was previously proposed by one of the inventors of the present application [see Japanese Patent Publication No. 61-41201]. The shafts are an inner shaft 1a and an outer shaft that slide smoothly relative to each other. It is a double shaft consisting of shaft 1b. The required number (usually 8) of main bones 2 are movably supported at the upper end of the inner shaft 1a, with one end gathered at a required angle (360 ° / 8 = 45 ° when 8). The required number (usually the same number of 8 main bones 8) of auxiliary bones 4 is at a predetermined angle at the upper end of the outer shaft 1b (when there are 8 main bones 45 °). Are assembled and movably supported, and the other ends movably support the main bone 2 at a position 2a near the support position on the inner shaft 1a. The grip handle 6a is provided at the lower end of the outer shaft 1b, and the auxiliary handle 6b is provided at the lower end of the inner shaft 1a. The coil spring 5 is arranged on the upper end of the inner shaft 1a so as to provide the elastic force between the outer shaft 1b and the inner shaft 1a in a direction to bring the upper end of the outer shaft 1b closer to the upper end of the inner shaft 1a. ing . An operating button 7a is provided on the grip handle 6a as a locking mechanism for temporarily stopping the mutual sliding of the outer shaft 1b and the inner shaft 1a. When the operation button 7a is pressed, the temporary stop of the mutual sliding is released. When the positional relationship between the outer shaft 1b and the inner shaft 1a is changed and the grip handle 6a is close to the auxiliary handle 6b and the main frame 2 is closed (first state), the temporary sliding of the mutual sliding is resumed. You can stop.

Normally, when the umbrella is closed, the grip handle 6a is in a position almost in contact with the auxiliary handle 6b. Then, in order to open the umbrella, press the operation button 7a with the finger of one hand while holding the grip handle 6a with one hand, the elasticity of the spring 5 pulls down the inner shaft 1a with respect to the outer shaft 1b. Sliding in the direction, whereby the auxiliary bone 4 acts to push and spread the main bone 2, and the umbrella opens. Although it can be used as it is, when fixing the main bone at the maximum open position in strong wind, etc., the hand holding the umbrella should separate the auxiliary handle 6b at the lower end of the inner shaft 1a from the grip handle 6a. When operated with a finger or the like, the second state shown in FIG. 5 is established, and the mutual sliding of the outer shaft 1b and the inner shaft 1a is temporarily stopped and locked.

To close the opened umbrella, press the operation button 7a with the finger of the hand holding the grip handle 6a. The coil spring 5 causes the tip of the outer shaft 1b to move slightly away from the tip of the inner shaft 1a. The main bone 2 is slightly closed due to the squeezing operation of the auxiliary bone 4 at this time. As described above, since the elasticity of the coil spring 5 is not so strong, in this closed state, the auxiliary handle 6b is pressed against a part of the body to bring the grip handle 6a close to the auxiliary handle 6b. By pulling lightly like this, the main bone is easily closed and the umbrella is closed, and the mutual sliding of the outer shaft 1b and the inner shaft 1a is temporarily stopped. However, in this conventional example, since the position 2a of the auxiliary bone 4 that supports the main bone 2 is located relatively close to the inner shaft 1a (about 7 to 10 cm) when the umbrella is open and in use, when wind is strong, etc. The main bone 2 and the cloth attached to the main bone 2 may become slack and become unstable.

Although the main bone 2 is stabilized by moving the position 2a away from the center, the auxiliary handle 6b extends below the grip handle 6a for a corresponding amount, which makes it inconvenient to use and has an unnatural shape. is there.

In order to eliminate this drawback, what is proposed is shown in FIG. 6 [see Japanese Utility Model Laid-Open No. 1-169116]. This further includes a lateral auxiliary bone 4a in addition to the auxiliary bone 4 in the structure of the conventional example shown in FIG. An outer end of the lateral auxiliary bone 4a movably supports the main bone 2 at a supporting position 2b at a substantially central portion of the main bone 2, and an inner end of the lateral auxiliary bone 4a is movably supported by an inner shaft 1a at a supporting position 4b. Further, the lateral auxiliary bone 4a is movably supported by the upper end of the auxiliary bone 4 at a support position 4c which is about 1/3 of its entire length from the inner end. With such an arrangement, the lateral auxiliary bone 4a is configured to be substantially horizontal as shown in the figure with the main bone 2 completely opened. The spring 5 is shown in a compressed state, and uses the elastic force in the extending direction as the operating force. The upper end of the spring 5 is fixed inside the tip mounting body 8. When the operation button 7a is pushed in the closed state, the spring 5 is still compressed, and the expanding force causes the main bone 2 to start to open, and as shown in FIG. 6, the lateral auxiliary bone 4a. The elastic effect of the spring 5 is strongly exerted in a state in which is substantially horizontal, and the main bone 2 strongly adheres to the cloth. At this time, mutual sliding of the inner shaft 1a and the outer shaft 1b is stopped by the stopper 9b.

A hole for locking when opened may be provided if necessary. Under special conditions, such as when it is made as a golf umbrella, under the conditions of use, it is more stable to provide such a hole in the inner shaft 1a.

[Problems to be solved by the device]

 In the conventional one-handed openable and closable umbrella as described above, one curved or bulging auxiliary handle is fixedly attached to the end of the inner shaft of the umbrella, which is the design of the handle of the conventional umbrella. Of course, it is provided according to the custom of the user. Although the design of such a curved or bulging auxiliary pattern certainly provides the user with the convenience of gripping and carrying, when such a design is applied to an umbrella for one-handed opening / closing operation, it is not suitable for processing and assembling. On the contrary, it causes a great deal of difficulty. Referring to the schematic view of the conventional structure of FIG. 4, the operation button 83 therein is fitted under the operation button base 81, and a fixing ring 91 for fixing the operation button is separately fixed on the inner shaft 90. An auxiliary handle 92 is attached and fixed to the lower end of the fixing ring 91 of the inner shaft 90. At the upper stage of the auxiliary handle 92, there is a sliding contact moving rod 921 which is provided in the grip handle 82 to move the grip handle 82 in sliding contact. When assembling it, the operation button base 81 is fixed to the lower end of the outer shaft 80, the fixing ring 91 is fixed to the inner shaft 90, and then the inner shaft 90 is further drilled in the outer shaft 80. Each umbrella is assembled one by one in its proper position, but the next step is the most difficult in the assembly process. The auxiliary handle 92 and the grip handle 82 are all assembled only after the supporting ribs of the entire umbrella have been assembled. Also, the grip handle 82 must be first fitted into the distal end of the inner shaft 90 before the lower auxiliary handle 92 is assembled, and if the auxiliary handle 92 is assembled first, the curved handle or bulge at the end thereof. Due to this structure, the grip handle 82 cannot be fitted into a predetermined position. In this case, since the auxiliary handle 92 must be fixed to the lower end of the inner shaft 90, when the grip handle 82 is fitted to the end of the inner shaft 90, be sure to open the umbrella first and move the outer shaft 80 upward. First, the sliding contact moving rod 921 above the auxiliary handle 92 is fixed to the end of the inner shaft 90, which causes inconvenience in assembling work.

When assembling each member of the umbrella itself, since the umbrella cloth is not bound to the umbrella bone, it is appropriate if the auxiliary handle 92 and the grip handle 82 cannot be assembled with the umbrella closed. Assembly work can be performed on various production lines. However, according to the current design of the auxiliary handle 92, when assembling the auxiliary handle 92, the umbrella is always opened first, and the grip handle 82 fitted to the end of the inner shaft 90 is first pushed up, so that the auxiliary handle 92 and The inner shaft 90 is fixed. This opening operation is quite troublesome in processing, and since the volume that it occupies after opening the umbrella is quite large, it occupies a considerably large space when assembling and processing, and the arrangement of the production line is It is difficult and can easily injure workers when the umbrella is open.

Further, the inner shaft 90 of the conventional example has a cylindrical structure, and the inner hole of the outer shaft 80 and the sliding contact rod 921 of the auxiliary handle 92 is also a round hole. In addition, even when it is used, relative rotation or wobbling is likely to occur due to external force, and the operation button base 81 is displaced, which causes a problem that it is difficult to operate.

An object of the present invention is to provide an umbrella that can be opened and closed with one hand, in which the assembling work on the production line is made safe and simplified, and the quality can be improved.

In order to achieve this object, the one-handed openable umbrella according to the present invention is provided with one axial groove on one side of the inner shaft and at the outer shaft ends where the operation buttons are fixed. Assembling the whole body by providing a convex block to be fitted, and at the same time, providing a convex block in the hole that fits into the concave groove of the inner shaft at the proper position inside the sliding contact moving rod fixed to the end of the inner shaft. In this case, it is possible to facilitate the positioning of the assembly, and at the time of use, the operation button base and the sliding contact moving rod are provided with a guide function to prevent wobbling. Therefore, the overall operability becomes more stable and reliable. In addition, by adopting a two-stage design for the auxiliary handle that is fixed to the lower end of the outer shaft and connecting one sliding contact moving rod and one auxiliary handle, it is not necessary to open the umbrella during assembly. First, insert the sliding contact moving rod into the end of the inner shaft to fix it, then insert the grip handle to the outside of the sliding contact moving rod, and fix the grip handle below the operation button base at the lower end of the outer shaft. Since the auxiliary handle having a curved shape or a bulge shape is connected to the end of the sliding contact moving rod, it is not necessary to open the umbrella during the assembling process, and the whole assembling becomes more convenient and smooth.

Finally, if the curved or bulging auxiliary handle 40 is fixed to the end of the sliding contact moving rod 30, the entire assembling flow can be completed. It is possible.

According to the present invention, an axial groove 11 is provided on the inner shaft 10 side, and the operation button base 21 has a unique outer side. A convex block 22 is provided which is fitted to the end of the shaft 20. The convex block 22 is fitted into the concave groove 11 of the inner shaft 10 and provides a guide function when the outer shaft 20 slides on the inner shaft 10 and, when used, between the outer shaft 20 and the inner shaft 10. Even better use stability can be obtained without causing relative rotation or wobbling.

Further, as shown in the cross-sectional structure of the sliding contact moving rod 30 of the present invention without showing in FIG. 3, the present invention shows that the inside of the sliding contact moving rod 30 is fixed to the end of the inner shaft 10. Since the in-hole convex block 31 that fits into the concave groove 11 of the inner shaft 10 is also provided at the proper position, positioning can be further facilitated during the assembly of the sliding contact moving rod 30, and the problem of assembly misalignment does not occur. After the whole is assembled, a guide function is applied between the sliding contact moving rod 30 and the operation button base 21 and the inner shaft 10 to prevent wobbling, and the overall operability is more stable and reliable. Will be things.
