Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an umbrella.

[0002]

2. Description of the Related Art A conventional umbrella is composed of a handle, an upper wheel fixed to the tip of the handle, a lower wheel fixed to the handle slidably below the handle, and a shaft that can be opened and closed radially. Stopped ribs, inner ribs on the bottom and outer ends on the center of the ribs to fix the angle between the ribs and handle at the time of opening. A waterproof sheet fixed to each end of the ribs to open and spread the ribs.

In a conventional umbrella, a handle, an upper potter's wheel, a lower potter's wheel, a rib, and a receiving bone constitute a link, and can be opened and closed by sliding the lower potter's wheel along the handle. That is, when the lower wheel is slid upward, the ribs swing upward with the upper wheel as a fulcrum due to the link action, and as a result, open radially about the handle. Then, the ribs are opened and the waterproof sheet is spread. In addition, when the lower wheel is slid downward, the ribs swing downward, and the waterproof sheet is pursued accordingly.

[0004]

However, in the case of the conventional umbrella, when the umbrella is closed, water droplets attached to the waterproof sheet may fall and hit the body. In addition, when getting into a car on a rainy day, the umbrella cannot be closed once the user enters the car, so the user must enter the car after closing. Therefore, you have to be hit by rain from when you close the umbrella to when you enter the car. Further, in the conventional umbrella, when the umbrella is closed, the wet surface of the waterproof sheet is exposed to the outside, so that even when entering the umbrella, various places and clothes such as a car seat may be wet. It is therefore an object of the present invention to provide an umbrella that does not get wet when closed and does not get wet after closing.

[0005]

In order to achieve the above object, an umbrella of the present invention comprises a handle, an upper wheel fixed to a tip of the handle, and a lower wheel slidably fixed to the handle below the handle. A wheel, a rib that is axially secured to the lower wheel so that it can be opened and closed radially, and a bone that determines the angle between the rib and the handle when the inner edge is upper and the outer edge is axially secured to the middle of the rib. And a waterproof sheet whose center portion is fixed to one of the upper and lower potter's wheels, and whose peripheral portion is fixed to each tip of the ribs so that the ribs can be opened and spread.

[0006] The umbrella of the present invention, like the above-mentioned conventional umbrella, has a handle, upper wheel, lower wheel, rib, and receiving bone,
Since the link is configured, the lower wheel can be opened and closed by sliding the lower wheel along the handle. However, in the umbrella of the present invention, unlike the conventional umbrella, the rib is fixed to the lower wheel, and the inner end of the receiving bone is fixed to the upper wheel.

Therefore, in the umbrella of the present invention, when the lower wheel is slid upward, each rib opens radially around the handle, and the waterproof sheet is spread. Also, when the lower wheel is slid downward, the ribs are fixed to the receiving bones in the middle part, so the fixed end swings downward with the lower wheel and the tip upwards, and the waterproof sheet Is pursed. Therefore, in the umbrella of the present invention, when the umbrella is closed, attached water drops do not fall on the body. Also, when getting into the car on a rainy day, the umbrella can be closed after getting into the car, so that it is not necessary to be drowned in the rain. Furthermore, in the umbrella of the present invention, when the umbrella is closed, the wet surface is hidden inside, so that various places and clothes such as car seats are not wetted.

In the umbrella of the present invention, the rib or the receiving bone is
When the inner section and the outer section are connected to the inner section via an elastic body such as a spring, the ribs expand and contract in accordance with the tension of the waterproof sheet, so that the waterproof sheet is not torn by the ribs. Also, when the tarpaulin is unfolded, it stays taut without sagging.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to the drawings. FIGS. 1, 2, 3, and 4 are cross-sectional views illustrating the closed state, the opened state, the state immediately before opening, and the opened state of the umbrella of the first embodiment, respectively. The umbrella 1 of this embodiment includes a handle 2, an upper wheel 3, a lower wheel 4, a rib 5, a receiving bone 6, and a waterproof sheet 7.

The upper wheel 3 is fixed to the upper end of the handle 2, and the lower wheel 4 is slidably fixed to the handle 2 below. The rib 5 is pivotally fixed to the lower wheel 4. The receiving bone 6 is pivotally fixed to the upper wheel 3 at the inner end and to the intermediate portion of the rib 5 at the outer end. I have.
A plurality of sets of the ribs 5 and the receiving bones 6 are provided, and are radially arranged around the handle 2. Therefore, by sliding the lower wheel 4 along the handle 2, the rib 5 opens and closes radially. At this time, the angle between the rib 5 and the handle 2 is determined by the receiving bone 6. The waterproof sheet 7 is made of a waterproof material such as vinyl, and has a central part fixed to the upper potter's wheel 3 and a peripheral part fixed to each end of the ribs 5. Therefore, the waterproof sheet 7
The rib 5 opens and closes radially, and is expanded or pursed.

The rib 5 is formed by joining two nodes. FIG. 5 shows the joining portion. FIG. 5 is an enlarged view of a portion V in FIG. As shown in FIG. 5, the rib 5 is fixed to the lower wheel 4 and includes an inner section 53 including a shaft fixing portion of the receiving bone 6 and an outer section 51 joined to the inner section 53 via a spring 52. . Therefore, when a force is applied to the spring 52, the position of the outer segment 51 changes, and the rib 5 expands and contracts.
Therefore, even when the waterproof sheet 7 is smaller than the length of the rib 5, the waterproof sheet 7 is not torn by the rib 5. In addition, when it is spread, it stays taut without sagging.

In the umbrella 1 of this embodiment, when the lower potter's wheel 4 is slid upward from the closed state shown in FIG. 1, the state shown in FIGS. 2 and 3 is changed to the open state shown in FIG. When the lower wheel 4 is slid downward from the state of FIG.
Since the rib 5 is axially fixed by the receiving bone 6 at the intermediate portion, the rib 5 swings so that the tip is directed upward, and as a result, the state shown in FIG. 1 is obtained.

In the closed state shown in FIG. 1, the lower wheel 4 is lowered to the lowermost position. In this state, since the waterproof sheet 7 is folded and no force is applied to the spring 52, the rib 5 does not expand or contract. The wet surface of the waterproof sheet 7 is hidden inside. In this embodiment, the shaft stop at the outer end of the receiving bone 6 is provided near the center of the rib 5, so that the rib 5 just fits between the upper wheel 3 and the lower wheel 4 when closed. Becomes compact.
Although the waterproof sheet 7 is still bent in the state of FIG. 2, the waterproof sheet 7 is stretched in the state of FIG. 3, and the rib 5 is shrunk by the tension.

In the state shown in FIG. 4, the shrunken rib 5 is stretched, and the waterproof sheet 7 is stretched without sagging. Here, as the distance from the shaft stop of the rib 5 to the lower wheel 4 is closer to the length of the receiving bone 6, the lower wheel 4 can be slid up, so that the space above the head is widened during use. be able to. In this embodiment, since the distance from the shaft stop of the rib 5 to the lower wheel 4 is slightly shorter than the length of the rib 6, the rib 5 and the rib 6 approach each other while being curved, and the lower wheel 4 is moved. It can be slid until it comes into close contact with the upper wheel 3. In order to prevent the lower wheel 4 from slipping down, a stopper may be provided on the handle 2.

In consideration of design and functionality, it is preferable that the waterproof sheet 7 is not only fixed at the center and the periphery, but is also fixed to the ribs 5 and the receiving bones 6 in other places. In the case of fixing at a portion other than the central portion and the peripheral portion, a ring-shaped projection may be provided at a predetermined position of the waterproof sheet 7 and the rib 5 or the receiving bone 6 may be slidably fixed through the ring. .

A second embodiment of the present invention will be described with reference to FIGS. FIG. 6 is a sectional view showing a second embodiment of the present invention, and FIG. 7 is an enlarged view of a portion VII in FIG. In this embodiment, both the main bone 5 and the receiving bone 6 include the inner segment 73,
An outer section 71 joined to the inner section 73 via a spring 72 is provided. Therefore, not only the main bone 5 but also the receiving bone 6 can be expanded and contracted. In addition, since the rib 5 is axially fixed to the receiving bone 6 at the outer section 71, when a force is applied to the spring 72, the distance from the axial stop of the rib 5 to the lower wheel 4 changes. Therefore, the umbrella 1 can be opened and closed more smoothly, and when the umbrella 1 is opened, it is easy to slide the lower wheel 4 until it comes into close contact with the upper wheel 3. Note that, other than the above features, the third embodiment is the same as the first embodiment.

FIG. 8 is a sectional view of a third embodiment of the present invention. The umbrella 1 of this embodiment has a handle 2, an upper wheel 3, a lower wheel 4, a rib 5,
It is provided with a receiving bone 6 and a waterproof sheet 7.
However, they differ in that they are fixed to the lower wheel 4 at the center and to the tips of the ribs 5 at the periphery. In this embodiment, when the umbrella 1 is closed, the ribs 5 and the receiving ribs 6 are hidden by the waterproof sheet 7, so that the design is excellent.
