Description

Detailed Description of the Invention

[0001]

[Industrial field of application] A plastic sheet made of vinyl or the like is used as a whole, and consists of an umbrella part, a hollow bone part, and a hollow handle part. When not in use, it can be folded into a pocket tissue to fold a pocket, a handbag, etc. (EN) A folding umbrella made of a plastic sheet, which is carried in a container and is expanded when in use so that the hollow bone portion and the hollow handle portion can be filled with air to be inserted into an umbrella shape.

[0002]

[Prior Art Problem] Everyone has the experience of having trouble when he / she is in the rain when he / she is out and about without having an umbrella. Therefore, recently, folding umbrellas that can be folded small and stored in a bag or handbag and extremely inexpensive umbrellas called so-called vinyl umbrellas have been provided, but even the above-mentioned folding umbrellas are ordinary umbrellas that are foldable. Therefore, it is bulky and heavy,
It is annoying and troublesome to carry around at all times, and the vinyl umbrella is cheaper than other ordinary umbrellas, so it can not be carried around at any time, it is cheap and ugly, and how cheap it is, They do not sell well in places where it rains or rains.

In view of the above-mentioned circumstances, it is small and light weight, is not bulky and is inexpensive, can be carried in a pocket, a handbag, etc. on a daily basis, or can be easily obtained at a shop such as a station like a pocket tissue. Since it is extremely convenient to have such an umbrella, it has been requested to develop and provide such an umbrella.

[0004]

Therefore, the present invention comprises a thin, light, and durable plastic sheet such as vinyl as a whole,
It is foldable and small enough to fold into a pocket tissue, so you can easily carry it in your pocket, handbag, etc. at any time, and when you use it, you can immediately inflate it by inflating the balloon to inflate the umbrella. The present invention provides a folding umbrella made of a plastic sheet, which is capable of forming the above.

[0005]

That is, the present invention is to provide a whole with a plastic sheet, and to provide a circular or polygonal sheet-shaped umbrella portion, and to form a tubular shape from the peripheral portion of the umbrella portion toward the center. Forming a hollow bone part and projecting a tubular hollow handle part downward from the center, forming the hollow bone part and the hollow handle part in a mutually venting state, and forming a hollow bone part or a part of the hollow handle part. The problem is solved by a folding umbrella made of a plastic sheet in which an air inlet is formed.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will be described with reference to the drawings. The folding umbrella A made of a plastic sheet of the present invention is provided with a thin and durable plastic sheet such as vinyl as a whole and has a conventional shape such as a circle or a polygon. The umbrella portion 1 having the same shape as that of the umbrella is provided, and the inner or outer surface of the umbrella portion 1 has a tubular hollow bone which is radially directed from the peripheral portion toward the center and corresponds to the bone of a conventional umbrella. While forming the part 2,
From the center downward, a tubular hollow handle portion 3 corresponding to the handle of a conventional umbrella is formed in a protruding manner, and the hollow bone portion 2 and the hollow handle portion 3 are formed in a mutually vented state. Or, an injection port 4 for injecting air into the hollow portion in a part of the hollow handle portion 3.
Is formed.

[0007] If necessary, a tubular hollow reinforcing portion 5 is appropriately formed around the umbrella portion 1, between the hollow bone portions 2 or between the hollow bone portions 2 and the hollow stem portion 3 to prevent heavy rain or rain. Provided to withstand wind.

The hollow handle portion 3 may be a straight rod-like member similar to the handle of a conventional umbrella, or may be a loop-like member, that is, it protrudes from the inner surface of the umbrella member 1 and when the umbrella A is inserted, it becomes a hollow bone member 2. The shape is arbitrary as long as it is a shape suitable for stably supporting the umbrella portion 1.

The air inlet 4 provided at the tip of the hollow handle 3 is provided with a detachable plug or a valve structure capable of injecting and discharging air. It is configured such that the injection and filling of air into the portion 3 and the like and the retention and the discharge of the air from the hollow bone portion 2, the hollow stalk portion 3 and the like for the unused folding can be easily performed at any time.

[0010]

[Function] Since the whole is made of a plastic sheet, it is normally folded very small and carried in a pocket, handbag, etc., and when it is used, air is blown from the inlet 4 to the hollow bone portion 2, hollow handle. When the portion 3, the hollow reinforcing portion 5 and the like are injected and filled, each portion expands and the umbrella is formed into an open outer shape. Therefore, the hollow handle portion 3 is held and inserted.

After use, the valve, plug, etc. of the inlet 4 are opened to discharge the air in the hollow bone portion 2, the hollow stem portion 3, and the hollow reinforcing portion 5, and the bag is folded back to its original size and carried. To do.

[0012]

[Effect] Because it is made of plastic sheet such as vinyl and is thin and flexible, it can be folded in an extremely small size, and because it is extremely lightweight, it can be carried in a pocket, handbag, etc. at all times like a pocket tissue. effective. Also, as with a pocket tissue, it can be sold at a station shop or the like without being bulky and can be easily handled, so that it is convenient for both sellers and buyers.

In particular, at the time of use, it can be immediately formed into a shape similar to that of a conventional umbrella by simply taking it out from a pocket or the like, unfolding it, and injecting and filling air from the injection port, which is extremely convenient.

After use, after removing water and drying, air can be removed from the inlet to flatten it and fold it into small pieces for repeated use.

Since it can be easily manufactured by cutting the plastic sheet and heat-sealing it, it can be provided at a very low cost without the cost of materials and labor, and therefore, it is not a burden even if it is disposable only once. There is also an advantage that does not become.
