[0011]
As shown in FIG. 1, in a rubber balloon 1 pre-filled with a levitation gas schematically shown in partial cross section, as shown in FIGS. 2 and 3, the umbrella body 2 and the peripheral edge 3 of the umbrella body 2 are fixed. A parachute 7 including a group of a plurality of suspended cords 4, 4, a bundling portion 5 thereof, and a single hanging strap 6 is accommodated.
[0012]
The umbrella body 2 is folded, the support string group is also folded, and the lower ends of the support strings 4, 4 are united together at a binding part 5, and a single hanging strap 6 extends from the binding part 5. Only the lower end portion 8 of the hanging strap 6 is drawn out from the mouth-neck tube 9 of the rubber balloon 1 to the outside.
[0013]
FIG. 2 shows a state in which the parachute 7 is folded, and a weight body 11 such as an observation instrument is suspended from the lower end portion 8 of the normal hanging strap 6.
[0014]
FIG. 3 shows a state in which the parachute 7 opens the umbrella body 2 and falls.
[0015]
The lower end of the support string 4 group is integrally bound to the binding part 5, but the form of the binding part 5 may be arbitrary, and the lower end of the support string 4 group may simply be bound.
[0016]
FIG. 4 shows a rubber balloon with a built-in parachute to which the present invention is applied, and is the same as FIG. 1 except that a winding unit 10 is added. The hanging strap 6 is not simply folded and built in the rubber balloon 1 but is wound around the take-up portion 10 to facilitate the mounting of the parachute 7 including the hanging strap 6 in the rubber balloon 1. Is.
[0017]
The hanging strap 6 is wound around the winding portion 10 except for the lower end portion 8 drawn out of the mouth-and-neck tube 9 of the rubber balloon 1.
The winding of the hanging strap 6 around the winding portion 10 is, in particular, when the parachute 7 is dropped. 3 between the opened umbrella body 2 shown in FIG. 3 and the weight body 11 at both ends of the suspension strap 6 so as to be easily dissociated and stretched by the applied tension F applied to the suspension strap 6 in the vertical direction. Is wound around the winding unit 10.
[0018]
Different winding structures of the hanging strap 6 in the winding unit 10 are shown in FIGS. 5, 6, and 7. 5 and 6 show an embodiment of claim 1 .
[0019]
In FIG. 5, the hanging strap 6 is wound around the bobbin-shaped winding unit 10 (10A), and the winding ends 12 and 12 of the winding unit 10A are lightened at the notches 13 and 13 of the winding unit 10A, respectively. On the other hand, the mouth and neck portion 9 of the rubber balloon 1 shown in FIG. 1 is filled with a buoyant gas at the time of levitation and the sealing of the gas, as shown in FIG. Since the gas filling shut-off valve 16 is hermetically sealed, the balloon piece that has ruptured at a predetermined pressure always occupies a position below the parachute 7 and, as before, the parachute 7 is not crowned and immediately opened. Due to the applied tensions F and F at the time of dropping, the upper and lower winding ends 12 and 12 are easily disengaged from the cuts 13 and 13, and the hanging strap 6 suspends the weight body 11 and is extended. The parachute 7 opened in this state falls slowly on the ground or water.
[0020]
FIG. 6 shows another type of winding unit 10 (10B). The winding ends 12 and 12 of the hanging strap 6 wound around the winding portion 10B are locked to the flange portion 10D of the winding portion 10B by locking bands 14 and 14, respectively. When the vertical tensions F and F are applied to the hanging strap 6 at the time of dropping, the winding ends 12 and 12 are easily pulled out from the locking bands 14 and 14, and the hanging strap 6 is easily detached from the winding portion 10B. And stretched.
[0021]
A winding unit 10 (10C) shown in FIG. 7 is an embodiment of claim 2 . The winding portion 10C of the hanging strap 6 is gathered into an elongated shape, and the hanging strap 6 is wound in an overlapping manner by drawing an 8-shaped trajectory 10E around both front and back surfaces of the winding portion 10C of the elongated body. The suspension strap 6 is temporarily fixed by the temporary fixing portion 15 so that it can be dissociated by the tensions F and F applied to both ends of the hanging strap 6. The stop is released, and the hanging strap 6 is extended in a state where the weight body 11 is suspended. Of course, the shape of the winding unit 10 is not limited to the above-described embodiments.
[0022]
8 and 9 show an embodiment of claim 3 . The rubber balloon 1 is sealed with a gas-filled shut-off valve 16 which is sealed by filling the rubber balloon 1 with a light gas such as hydrogen or helium. The rubber balloon 1 that is light and filled with the light gas through the gas filling and shut-off valve 16 rises to a high altitude while suspending the observation weight body 11.
[0023]
At a predetermined altitude, as shown in FIG. 9, the rubber balloon 1 that has expanded into a spherical shape is ruptured and the parachute 7 is exposed, and is opened as shown in FIG. 3, and the weight body 11 is slowly put on the ground or water. Drop it. The fragments of the rubber balloon 1 do not interfere with the opening of the parachute 7 at all.
[0024]
When the gas shut-off valve 16 is hermetically bonded to the mouth and neck tube 9 of the rubber balloon 1, the parachute 7 in the rubber balloon 1 and the weight body 11 suspended outside the rubber balloon 1 are connected so as not to cause gas leakage. The attachment of the hanging strap 6 is a problem. There are three possible solutions.
[0025]
a, the suspension strap 6 is divided into two, the suspension strap upper half 6A is connected to the upper end 17 of the gas stop valve 16 in the rubber balloon 1, and the suspension strap lower half 6B is connected to the lower end of the gas stop valve 16 outside the rubber balloon 1. Tie to 18. In this case, the winding unit 10 is attached to the hanging strap upper half 6 </ b> A within the rubber balloon 1.
[0026]
b. The hanging strap 6 is sealed and bonded to the mouth-neck tube 9 of the rubber balloon 1 by the tie band 19 and the like together with the valve 16 along the outer peripheral surface of the gas filling shut-off valve 16. In this case, the upper half of the hanging strap 6 remains in the rubber balloon 1 and is connected to the parachute 7 via the winding portion 10, and the lower half of the hanging strap 6 suspends the weight body 11 outside the rubber balloon 1.
[0027]
C. A winding part is directly connected to the upper end side of the gas filling shut-off valve 16, and the hanging strap 6 is wound around the winding part.
[0028]
【The invention's effect】
In the invention of claim 1, since the parachute is folded and stored in advance in the rubber balloon, it is unnecessary for the user who needs to install the gas filling stop valve or the like when using the balloon, to incorporate the parachute, The lower end of the parachute suspension strap is fixed to the mouth and neck of the rubber balloon, so when the rubber balloon bursts in the high sky, the parachute is always positioned above the fragment of the rubber balloon and exposed without being crowned by the fragment. It is fully open without hindrance and produces an effect (first effect) that allows the weight body to be slowly lowered.
[0029]
Further, in the invention of claim 1 , since the hanging strap is wound around the winding portion so as to be easily dissociable by the applied tension at the time of dropping, the interior operation of the long hanging strap is extremely difficult when the parachute is built in the rubber balloon. It is easy and produces an effect (second effect) in which the operation when using the balloon can be carried out without hindrance.
[0030]
Furthermore, in the invention of claim 1 , both ends of the hanging string that is shortly wound around the winding unit are automatically dissociated from the winding unit by the tension applied to the hanging string when dropped, and the hanging string is predetermined. The effect of not causing any hindrance to the operation at the time of observation of the suspended heavy body is obtained.
[0031]
In the invention of claim 2 , in addition to the first effect and the second effect, since the winding portion has an elongated shape, no special parts are required, and a lightweight board piece, cardboard piece, or the like is sufficient. It can be used without adding extra weight when the balloon is raised, and it has the effect of reducing the overall weight of the rubber balloon in addition to the ease of operation.
[0032]
In the invention of claim 3 , since the parachute is built in the rubber balloon and the gas-filled shut-off valve is sealed and attached to the mouth-and-cervical canal, the weight body of an observer or the like is used at the ballon spot of the rubber balloon. The effect of being able to ascend the observation balloon and so on, and to safely and reliably carry out the observation and descend the heavy body to the ground or the water, simply by attaching the gas and filling the gas. Play.
