BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable umbrella, and more particularly to a foldable portable umbrella.

[0002]

2. Description of the Related Art First, a conventional portable umbrella will be described with reference to the drawings. FIG. 26 is a front view schematically showing a configuration of a conventional portable umbrella. Referring to FIG. 26, portable umbrella 50
0 is the tension bone 520, handle 530, vinyl sheet 54
0, grip part 550, cap 560 and supporting bone 57
0 is included. One end of the handle 530 supports one end of a predetermined number of tension bones 520. The tension bone 520 is composed of at least two or more elements. Therefore, the tension bone 520 can be bent in a predetermined direction at the joint portion of the elements. A vinyl sheet 540 is attached to the other end of the tension bone 520. The vinyl sheet 540 is held by being sandwiched between one end of the handle 530 and the cap 560. Therefore, when the tension bone 520 is open, the vinyl sheet 540 is open in the outer peripheral direction around the handle 530. A grip portion 550 is attached to the other end of the handle 530. A cylinder 580 is fitted in the handle 530. The cylinder 580 is movable in the directions of arrows A and B along the handle 530. One end of a support bone 570 is supported by the cylinder 580. The other end of the support bone 570 is joined to the joint of the elements of the tension bone 520.

In the conventional portable umbrella 500, the opening and closing of the umbrella is performed by sliding the cylinder 580 along the handle 530 in the directions of arrows A and B. This cylinder 580
, The supporting bone 570 presses the tension bone 520 in the direction of arrow A. By the pressing of the support bone 570, the tension bone 520 opens in the outer peripheral direction around the handle 530, and the umbrella is in an open state.

[0004]

Referring to FIG. 26, gravity is generally applied in the direction of arrow B when an umbrella is used. In the conventional portable umbrella, the portable umbrella 500 tends to be closed by the gravity in the arrow B direction. Prevent this,
Cylinder 580 and support bone 570 to keep it open
Is installed. That is, when the cylinder 580 is moved in the direction of arrow A and locked, the support bone 570 is extended in the outer circumferential direction around the handle 530.
Press 20. Due to this pressing, the portable umbrella 500 is kept open. Thus, the cylinder 580 and the supporting bone 570 contribute to keeping the umbrella open. However, the provision of the cylinder 580 and the supporting bone 570 complicates the mechanism of the umbrella. Therefore, when the portable umbrella 500 is folded, it is difficult to fold it compactly. Therefore, even if the umbrella is folded, its size is relatively large, and there is a problem that it is difficult to carry the umbrella in a pouch or a bag.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and a portable umbrella which has a simpler mechanism and which can be made more compact in a folded state. The purpose is to provide.

[0006]

The portable umbrella of the present invention includes a support plate, a handle, a bone, a seat, a container for a grip, and a cap. The support plate has first and second main surfaces, and has a hole formed therethrough from the first main surface to the second main surface. The handle is inserted through a hole in the support plate, and is provided movably from the first main surface side to the second main surface side through the hole. There are three or more bones and the first
Has one end supported on the main surface of the handle and is rotatably mounted about the one end between a closed position and an open position with respect to the handle. Each of these bones and stalks
It is possible to consist of a plurality of elements, the elements being superimposed on one another to a length of substantially a single element. The seat has a peripheral edge attached to the other end of each of the bones and a central portion attached to the support plate. The handle container can be attached to the end of the handle on the second main surface side, and the handle and the bone are overlapped with each other to form a substantially single element. It can be stored. The cap is attachable to either end of the handle on the first and second major surface sides.

[0007]

First, the operation of the portable umbrella of the present invention for shifting from the opened state to the folded state will be described. The open state of the portable umbrella of the present invention is a state in which the handle has moved most to the second main surface side. Also, the elements of this handle do not overlap each other and the length of the handle is the largest. Each bone is in an open position by being supported by the first main surface of the support plate. Also, the elements of each bone do not overlap each other, and the length of the bone is the largest. Since the length of each bone is the longest, the sheet attached to the other end of each bone is in a stretched state.

[0008] To collapse the above open state, the lengths of the bones are adjusted to approximately the length of a single element by first overlapping the elements of the bones.
As a result, the sheet becomes slack. Next, each bone is moved to a closed position by rotating each bone about one end of the bone. At the time of rotation of the bone, the sheet is loosened, so that the rotation is smoothly performed. Next, the length of the handle is adjusted to the length of a substantially single element by overlapping the elements of the handle with each other. By pushing the handle toward the first main surface side through the hole of the support plate, the handle is brought to the state most moved to the first main surface side.

As described above, the portable umbrella of the present invention shifts from the open state to the folded state. That is, the folded state is a state in which the handle has moved most to the first main surface side. Also, the elements of the handle overlap each other and are approximately the length of a single element. Bones
In the closed position, the bone elements also overlap each other to a length of approximately a single element. The sheet is loose and wrapped around a bone or handle.

In the portable umbrella of the present invention, the bone is supported on the first main surface. Therefore, in the open state of the umbrella, the bone is maintained in the open position by the first main surface even under the influence of gravity. Therefore, unlike the conventional form umbrella shown in FIG. 26, the cylinder 580 and the support bone 570 for supporting the tension bone 520 are unnecessary. Therefore, in the portable umbrella of the present invention, the mechanism can be simplified.

Further, in the portable umbrella of the present invention, when shifting to the folded state, the bone moves from the open position to the closed position. The bone moved to the closed position extends from the support plate in a direction from the second main surface to the first main surface. In this state, the elements of the handle do not overlap each other, and the length of the handle is the largest. The handle extends from the support plate in a direction from the first main surface to the second main surface, that is, in a direction opposite to the bone in the closed position. Therefore, in this state, the length of the umbrella is very large and not compact. Therefore, by providing a hole in the support plate, the handle can move from the first main surface side to the second main surface side through the hole. That is, the handle is movable to extend in the same direction as the bone in the closed position. By moving the handle, the length of the umbrella can be reduced as compared to a state in which the bone and the handle extend in the opposite directions from the support plate. Further, the handle is composed of a plurality of elements, and the elements can be overlapped with each other to make the length of the element almost single. This allows
The length of the handle can be reduced, and the length of the umbrella can be further reduced. Thus, the portable umbrella of the present invention can be folded compactly. Therefore, it is easy to enter a pouch or a bag, and it is very easy to carry. In addition, the container for the grip part, when the umbrella is open,
By being attached to the end of the handle on the second main surface side, it becomes a grip portion of the umbrella, and makes it easier to grip the umbrella. Moreover, since the handle and the bone can be stored in the grip portion container when the umbrella is folded, the handle and the bone can be stored compactly and can be easily carried. In addition, when the umbrella is open, the cap is attached to the end of the handle on the first main surface side, thereby playing a role of firmly fixing the sheet to the support plate. In addition, the cap is attached to the second main surface side end of the handle when the umbrella is folded,
It becomes a lid for closing the opening end of the above-mentioned container for grip portion, and enhances the tightness of the container. Accordingly, even if the sheet is wet with rain, the moisture can be sealed in the container when the umbrella is folded, and the moisture can be prevented from leaking out of the container.

[0037]

[Effect of the Invention] In the portable umbrella of the present invention, the bone is first.
Is supported on the main surface. Therefore, when the umbrella is open, the first main surface keeps the bone in the open position even under the influence of gravity. In this way, the mechanism can be simplified since the bone is maintained in the open position by the first main surface.

Further, in the portable umbrella of the present invention, a hole is formed in the support plate, and the handle can be moved from the first main surface side to the second main surface side through the hole. Also, by superimposing the bone and handle elements on each other, the length of the bone and handle can be made substantially the length of a single element. Thereby, the portable umbrella of the present invention can be stored more compactly in the folded storage state. Therefore, it is easy to put in a pouch or a bag, and it is very easy to carry. When the umbrella is open, the grip portion container is attached to the end of the handle on the second main surface side to form a grip portion of the umbrella, making it easier to grip the umbrella. On the other hand, since the handle and the bone can be stored in the grip portion container when the umbrella is folded, the handle and the bone can be stored compactly and can be easily carried. In addition, when the umbrella is open, the cap is attached to the end of the handle on the first main surface side, thereby playing a role of firmly fixing the sheet to the support plate. When the umbrella is folded, the cap is attached to the end of the handle on the second main surface side, and serves as a lid for closing the opening end of the grip portion container, thereby enhancing the tightness of the container. Accordingly, even if the sheet is wet with rain, the moisture can be sealed in the container when the umbrella is folded, and the moisture can be prevented from leaking out of the container.
