JPH08308621A - Revolutionary air umbrella - Google Patents

Abstract

PURPOSE: To provide an air umbrella having a double airtight construction of upper and lower sheets from which the umbrella is quickly shaped by an inflating operation by sending air from a stopper and which is instantaneously shrunk and folded by discharging the air by opening the stopper, so that the umbrella is a very light, small, and portable without becoming a nuisance and trouble when the rain stops. CONSTITUTION: The main body portion D of an umbrella is made of a material such as a vinyl sheet or a similar material which is air-tight, soft, and tough, and has a double structure of upper and lower sheets A and B. By injecting air from a stopper 5 to a portion between the sheets A and B, the air umbrella is instantaneously quickly formed. By opening an air discharging plug F and using the palms of hands, the air is instantaneously quickly discharged and the umbrella results in a super light shrunk shape.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rain umbrella that is convenient for carrying and storing due to its revolutionary ultra-miniaturization by the "revolutionary air umbrella".

[0002]

2. Description of the Related Art A conventional umbrella (umbrella) has been constructed by three parts, as shown in FIG. 2, a waterproof fabric part (i), a frame part (ro) and an umbrella handle part (ha). is there. Therefore, the skeleton member has been used or stored only by expanding and folding it. For this reason, when carrying it after raining
It is also a very troublesome obstacle because of its feeling and its weight. Therefore, it is also always the top of misplaced items. This is also common to conventional "folding umbrellas" that are folded up. In this way, thanks to the umbrella used during the rain, we forget about it after the rain, and if it is a little long and useless rain umbrella for subsequent carrying, the air umbrella of the present invention makes it an ultra light and small storage form, so the bag, Whether you store it in one corner of a bag, put it in your pocket, or carry it with one hand, it feels almost empty.

[Problems to be Solved by the Invention]

(A) The "revolutionary air umbrella" of the present invention has a long history of rain umbrellas (umbrellas) up to the present time, and does not use any "skeleton material" that is a main component of the umbrella. The deployment of the umbrella form is instantly completed by the blowing and expanding operation of (air). (B) Further, due to the opening of the top exhaust hole (E) and the operation of palm pressure, an ultra-light and small contraction form is instantaneously obtained. (C) It is an epoch-making creative umbrella that makes it possible to carry a boneless, foldable, ultra-light, small-sized portable device by such simple and simple instantaneous operations. (D) As a result, the bulkiness of the conventional "framework" umbrella after the rain is over, the weight of the umbrella, and the troublesomeness of carrying it and the annoyance of disturbing feelings are released. (E) Since it is the smallest and lightest foldable form, it can be embarrassed if it is always stored in a corner of a bag, bag, etc., regardless of the rainy season, even if it rains unexpectedly due to a drastic change in the weather on the go. There is no need to do this, and it can be used as a convenient air umbrella. This is especially true when traveling near and far.

[Configuration and Means for Solving the Problems]

(A) As shown in Fig. 1, the umbrella body fabric is colorless and transparent or colored vinyl sheet material, or similar to this, is absolutely airtight and is extremely tough such that it does not break or crease and is smooth and flexible. It is made of material. (B) This is made into a double sheet structure of upper and lower double, and the entire periphery of the upper and lower overlapping is formed on the "entire circumferential crimp flange (C)" of absolutely airtight electrothermocompression (electrothermal sealer, electrothermal press). (C) Therefore, if the handle plug (6) of the air blow-in hole of the third hollow joint shaft (3) is opened and the air blow-in hole (5) is held in the mouth and the air is blown deep and long, the air blow-out hole (4) The air chamber (D), which is absolutely airtight, immediately expands to form a rain umbrella by the air filling from (1). (D) Also, remove the top exhaust hole plug (F) of the main hollow shaft (1) at the center of the air chamber (D), and open the top exhaust hole (E) and operate the palm pressure to open the air chamber (D). The air that has been fully filled is instantly exhausted and becomes an ultra-light and small foldable storage form. (E) The umbrella handle portion is a stretchable joint handle (2) (3).

[0005]

【Example】

(B) When using this air umbrella, first tightly and securely tighten the top exhaust plug (F) of the top exhaust hole of the main hollow shaft (1), and then the third hollow joint shaft handle ( Remove the handle plug (6) of 3), put the air blow hole (5) in your mouth and blow a deep and long breath. (B) At this time, the backflow prevention valve (7) acts so that the air is not discharged backflow. (C) The air thus blown into the air chamber (D) is blown out from the air blowing hole (4), and the air is blown and expanded to form a rain umbrella shape. (D) When storing this air umbrella after use, remove the top exhaust hole plug (F) at the upper end to remove the air filled in the air chamber (D) from the air discharge hole (4). ), Exhaust is completed instantly through the top exhaust hole (E),
It becomes an ultra-light and small storage form. (E) In this case, the material itself is thin and flexible even if it is stored in a convoluted convolution, so when it is expanded again, it does not become wrinkled and a crisp and smooth umbrella surface appears. (F) Since this air umbrella is expanded and formed by injecting and filling with air, its main hollow shaft (1) is used as an upright central axis for gripping and supporting force in a strict umbrella shape. Therefore, when it is used during rainfall, even if it encounters a fairly strong wind and rain, it adapts to this, so-called "Kaze ni Yanagi", flexibly receives and absorbs it, and keeps the original umbrella form. Go on. (G) In this respect, the conventional rain umbrella has a framed hardwood structure, so it resists strong wind and rain from the front and resists it. Eventually, this wind blows it into incoherent and terrible damage. There are marked differences compared to the many cases. (H) Thus, the folding storage capacity of the air umbrella after the rain is really revolutionary and small compared with the conventional rain umbrella and the conventional folding umbrella.

Since this "Revolutionary Air Umbrella" is mainly made of vinyl sheet material, it exhibits its various characteristics such as its corrosion resistance and its water and moisture resistance, and its service life is extremely long, and Since it is cheap, it is the most suitable as a household item.

All of these have been empirically demonstrated and confirmed as a result of a number of rigorous practical trial tests over a long period of time, their great merit and their outstanding convenience performance.
