Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a kind of one-handed foldable umbrella that can be folded by one-handed operation.

[0002]

[Prior art]

 The conventional automatic umbrella generally refers to one that can be automatically opened, but recently, an umbrella that can be automatically folded has been developed in response to actual demand. A slightly currently known structure of this type of umbrella is one in which parts such as a pull rod and a spring are provided inside the center rod, but since the space inside the center rod is very small, many parts If it had to be mounted, it took time to manufacture, and interference between parts was likely to occur, which was not practical.

[0003]

[Problems to be solved by the device]

 In view of the above-mentioned drawbacks of the conventional technique, an object of the present invention is to achieve automatic folding of an umbrella with a simple structure in which a movable sleeve is added to the outside of the center rod.

[0004]

[Means for Solving the Problems]

 The one-handed foldable umbrella of the present invention is an umbrella having a center rod whose upper part is connected to the ribs and receiving bones and whose lower end is connected to the handle. One ring body is engaged with and interlocked with it. A flange is provided on the upper end of the movable sleeve, and a spring is attached between the flange and the upper end of the movable wheel under the flange. It is characterized in that the movable sleeve is interlocked with the movable wheel and the movable wheel is slid downward to achieve one-handed folding.

[0005]

[Action]

 The one-handed foldable umbrella of the present invention is provided with a movable sleeve on the outside of the center rod, and the lower part of the movable sleeve and the one ring body are coupled to each other, and a flange is formed on the upper end of the movable sleeve, so that the movable wheel is attached to the outside of the movable sleeve. A spring is provided between the movable wheel and the flange on the upper end of the movable sleeve, and the movable wheel is pulled down with the movable sleeve by the thumb and forefinger of the hand holding the handle. The umbrella can be folded by one hand by moving it downwards by interlocking.

[0006]

【Example】

 As shown in FIGS. 1 and 2, the present invention includes a center rod 1, a movable wheel 2, a receiving bone 3, a rib 4, and a handle 5 connected to the lower end of the center rod 1. Since the sleeve 6 is installed, the movable sleeve 6 is slidably attached to the outer periphery of the center rod 1, and the concave hole 61 provided at the lower end thereof is fitted to the convex grain 71 of the ring body 7. Then, one spring 72 is provided in the opening at the lower part of the ring body 7 and integrated with the ring body 7, and the upper part of the handle is fitted into the opening end. A flange 62 is formed on the upper end of the movable sleeve 6, another spring 63 is attached below the flange 62, and the movable wheel 2 is attached to the outer periphery of the movable sleeve 6. The state of the present invention when the umbrella is opened is as shown in FIG. 2, and the upper end of the movable wheel 2 tops the spring 63. At this time, the lower included angle between the support bone 3 and the center rod 1 is smaller than 90 °, and the movable cross wheel 2 is biased upward by being pressed against the ribs 4 and the support bone 3 of the raw cloth, and is fixed to open the umbrella. Form a state.

When folding the umbrella, the user pulls the ring 7 downward with one hand. Then, the movable sleeve 6 moves downward in conjunction with the ring body 7, the upper flange 62 of the movable sleeve 6 presses the movable potter's wheel 2 downward and slides it downward, and as shown in FIG. When the lower included angle of the support bone 3 and the center rod 1 exceeds 90 °, the movable cross wheel 2 slides down rapidly due to the pressure from the above-mentioned raw cloth, thus achieving the folding of the umbrella with one hand. .

[0008]

[Effect of device]

 The present invention achieves folding of the umbrella by one-handed operation with a simple structure in which a movable sleeve is provided on the outer circumference of the center rod, and the manufacturing is easy, and the manufacturing time and cost are low. It is practical because it does not have the problem of mutual interference between parts, which was present in the conventional structure in which interlocking parts were provided inside a narrow center rod.
