2. Description of the Related Art Conventionally, in order to prevent water droplets attached to a rain-wet umbrella from falling on the inside of a car or the floor of a store and polluting the surrounding area, a closed umbrella is covered with a plastic bag or the like. It was generally performed to wrap and attach a plastic bag or the like by using an instrument.

[0003]

However, in such a case, it is relatively troublesome to close the rain-wet umbrella and insert it into a plastic bag or the like, and at that time, the hand gets wet, and it is inserted to prevent it. The use of tools has the disadvantages of requiring large-scale tools and equipment. In addition, there is a possibility that water drops adhering to the umbrella cloth may be accumulated in the vinyl bag and the vinyl bag may be broken and the water drops may leak out.

In view of the above, the present invention provides a device for capturing water droplets attached to an umbrella cloth by simply and specially devising it. When the umbrella wet with rain is closed and the umbrella side is simply raised, the water droplets attached to the umbrella cloth. Is naturally and accurately captured and stored in the storage container attached to the tip end of the center rod, and the water droplets are surely prevented from falling on the floor surface and the like to stain the surrounding area. It is not necessary to use a conventional plastic bag or its attachment device with the various difficulties described above, and the opening / closing valve of the storage container is automatically opened / closed according to the opening / closing operation of the umbrella, which is suitable for use. It is an object of the present invention to provide a water drop capturing device for an umbrella which is excellent in stability, durability and decorativeness.

[0005]

To achieve the above object, the present invention employs the following means. That is, a water drop container that is attached to the outer surface of the protruding end of the center rod of the umbrella and that catches and stores the water droplets that have adhered to the umbrella cloth when the umbrella is closed, and is slidably arranged in the center rod of the umbrella. The sliding metal fitting is pushed by the lower wheel through a projection protruding from the opening window that opens on the outer surface of the center rod between the upper stopper and the lift stopper of the lower wheel that protrudes on the outer surface of the center rod. The sliding metal fitting and the opening / closing valve which is normally closed at the drainage port of the water drop container via an elastic member or a magnetic member are used to push or pull the opening / closing valve. The feature is that the opening / closing valve is automatically opened / closed in accordance with the opening / closing operation of the umbrella through the raising / lowering of the lower wheel by connecting as much as possible.

When the rain-wet umbrella is closed and stood with the stone side facing down, water droplets adhering to the umbrella cloth are attached to the outer surface of the tip of the umbrella rod protruding toward the stone side. It is dropped inside and received, and is introduced into the storage container through the pipe. At the time of introducing the water droplets, the residual air in the storage container is discharged to the outside through the pipe as the water droplets are introduced, and the water droplets are smoothly introduced.

An opening / closing valve is provided at the drainage port of the water drop container, and the opening / closing valve is arranged so as to be normally closed via an elastic member such as a spring or a magnetic member such as a magnet.

A sliding metal fitting, which is pushed by the rise of the lower lock for opening and closing the umbrella, is arranged in the center rod of the umbrella. The sliding metal fitting and the opening / closing valve of the storage container are provided by the sliding metal fitting. The on-off valve is connected so as to be pushed or pulled, and the on-off valve is automatically opened and closed through the connecting means for connecting the sliding metal fitting and the on-off valve when the umbrella is opened and closed by raising and lowering the lower wheel. It A protrusion is integrally connected to the sliding fitting so that the protrusion protrudes to the outside from an opening window formed on the outer peripheral surface of the center rod, and the opening window stops the lower rocker from rising when the umbrella is opened. Therefore, it is formed on the outer peripheral surface of the center rod between the stopper projected on the outer surface of the center rod and the upper crater for stopping the lowering of the lower wheel when the umbrella is opened. Therefore, the sliding metal fitting is pushed through the contact between the lower rocker and the protrusion due to the ascent along the lower rocker when the umbrella is opened, and is slid in the middle rod to rise together with the lower rocker. Then
The protrusion stops contacting the front end wall surface of the opening window to stop the rise.

The connecting means for connecting the on-off valve of the water drop accommodating container and the sliding fitting slidably arranged in the inner rod may have various modes. Use one that abuts or fixes the front end of the protruding tip on the on-off valve. In this case, if the lower rocker is raised along the center rod when the umbrella is opened, the lower rocker hits the protrusion of the sliding fitting protruding from the opening window and pushes the sliding fitting upward, pushing the on-off valve to the sliding fitting. Then, the water drops in the container are discharged onto the opened umbrella cloth. When the lower wheel is lowered while the umbrella is closed, the pressing force on the on-off valve by the sliding metal fittings via the lower wheel is released, and the on-off valve returns to its original position due to the elastic force of the spring or the magnetic force of the magnet, and closes and closes. When the umbrella that has been umbrellad is placed upright with its stone head side down, water droplets travel down the umbrella cloth and are dripped downward, and are captured and stored in the storage container.

As another mode of the connecting means for connecting the on-off valve and the sliding metal fitting, a roller in which the other end of the wire rope whose one end is fixed to the on-off valve is disposed inside the middle rod behind the sliding metal fitting. It is wound around and the tip is fixed to the rear end of the sliding fitting. In this case, when the sliding metal fitting is pushed upward due to the rise of the lower lock when opening the umbrella, the wire rope that is fixed to the rear end of the sliding metal fitting and wound around the roller is pulled to open the on-off valve and close the umbrella. At this time, when the lower wheel is lowered to release the pressing force on the sliding fitting, the on-off valve returns to its original position and closes due to the elastic force of the spring or the magnetic force of the magnet.

The valve mechanism of the drain port of the water drop container including the on-off valve includes a receiving cylinder in which a hollow cylindrical magnet is attached to an annular magnetic plate disposed in the drain port, and a circular magnetic plate. In some cases, an on-off valve having a magnet fitted and attracted inside the receiving cylinder is attached so as to protrude.

In some cases, the outer surface of the tip end portion of the center rod that protrudes toward the projection side is covered with a cover made of a flexible material such as resin.
