By mounting the bag body 3 into which the gas having a specific gravity smaller than that of air is injected near the one end portion 4a of the center rod 4 of the umbrella body 2, the umbrella 1 is lightened and the usability is improved. , Can reduce fatigue.

FIG. 4 is a sectional view showing the pressure container 20 and the bag body 3 in a simplified manner. As shown in FIG. 4A, the thickness T <b> 1 of the first portion 23 of the bag body 3 in the vicinity of the suction / discharge port 18 is the thickness T <b> 2 of the second portion 24 which is a remaining portion far from the suction / discharge port 18. It is formed larger.

The pressure container 20 is provided with an intake / exhaust port 22 for intake and exhaust of gas, and an intake / exhaust port 22.
A container valve 21 for communicating / blocking between the inside and the outside is provided. When injecting gas into the bag 3, confirm that no gas has entered the bag 3, remove the fastening member 16 and the plug 19 from the suction / discharge port 18, and apply pressure to the suction / discharge port 18 of the bag 3. It is attached to the suction / discharge port 22 of the container 20. At this time, since the stopper 19 and the suction / discharge port 22 are formed to have substantially the same outer diameter, they can be easily mounted. The attached suction / discharge port 18
Further, it is fastened by the fastening member 16 to prevent gas leakage.

Next, the container valve 21 is opened, the pressure container 20 and the bag body 3 are communicated with each other, and the gas in the pressure container 20 is filled into the bag body 3 to expand the bag body 3. After the bag 3 is completely spread and the filling of the gas is completed, the container valve 21 is closed to shut off the bag 3 and the pressure container 20. Thereafter, the fastening member 16 is loosened, the suction / discharge port 18 of the bag body 3 is removed from the suction / discharge port 22 of the pressure vessel 20, a plug 19 is fitted into the suction / discharge port 18, and the fastening member 16
To conclude. In this way, the gas is filled in the bag 3.

When the umbrella 1 is not used, the skeleton 9 is removed from the lowering wheel 8, the bag 3 is removed from the umbrella body 2, and the skeleton 9 is attached to the lowering wheel 8 again to close the umbrella body 2. The gas in the removed bag 3 is returned to the pressure vessel 20 again.

When the gas in the bag 3 is returned to the pressure container 20, the stopper 19 is first removed from the bag 3, the suction / discharge port 18 of the bag 3 is attached to the suction / discharge port 22 of the pressure container 20, and the fastening member 16 is attached. Conclude with. Next, the gas is moved away from the container valve 21 and moved to the first portion 23 having a thickness T1 near the container valve 22 of the bag body 3 by, for example, pressing the gas in the second portion of the bag body 3 having the thickness T2 by hand or the like. Let it.

As shown in FIG. 4 (2), after the gas from the second portion 24 is transferred to the first portion 23, the first portion 23
Around the second thickness portion 24 from the outside of the bag body 3 with a string 25
Tied by to block between the first and second portions 23, 24 and prevent gas from moving from the first portion 23 to the second portion 24. In this case, instead of the string 25, the first portion 23 and the second portion 24 may be cut off by hand.

After that, the container valve 21 is opened, the inside of the bag body 3 and the inside of the pressure container 20 are communicated with each other, and the gas in the bag body 3 is pressurized.
Move within 0. At this time, the pressure in the pressure vessel 20 is P1, the pressure in the bag 3 is P2, and the relationship between the two is P1.
The gas inside the bag body 3 is moved into the pressure vessel 20 by pressing the bag body 3 from outside the bag body 3 by, for example, a hand or the like so that 2> P1.

After all the gas in the bag 3 has moved into the pressure container 20, the container valve 21 is closed and the bag 3 is removed from the pressure container 20. The suction / discharge port 18 of the bag 3 is closed again with the plug 19 to prevent air or the like from entering the bag 3.

Therefore, by moving the gas in the second portion 24 to the first portion 23 as described above, instead of applying the pressure to the entire bag body 3 to move the gas into the pressure vessel 20, When the pressure P2 of the first portion 23 is increased and the container valve 21 is opened, the pressure container 2 is easily removed from the inside of the bag body 3.
The gas can be moved to zero. At this time, the thickness T1 of the first portion 23 is large enough to withstand the pressure P2, so that the strength of the first portion 23 is large and the bag 3 is prevented from being damaged.

The pressure container 20 is pressed by pressing the entire bag body 3.
In contrast to the case of moving the gas inside, when the gas in the first portion 23 is moved into the pressure vessel 20, since the surface area of the first portion 23 is smaller than the surface area of the entire bag body 3,
By pressing the first portion 23 by hand, the pressure vessel 20
The work of moving the gas inside is easy.
