On the other hand, since the bulk becomes smaller when degassed, the storage volume is reduced when not in use, which improves usability.

With reference to FIG. 8, when the storage container 71 rolls over on a flat surface 61 such as the ground, the protective members 82a and 82b come into contact with the flat surface 61 so that the storage body 75 does not come into contact with the flat surface 61. It is set. With such a configuration, the storage body 75 is less likely to be directly impacted during transportation, storage, and dropping, so that the safety of the storage state is improved.

FIG. 1 is a schematic perspective view of a storage container structure composed of a storage container according to the first embodiment of the present invention, and FIG. 2 is a schematic end view seen from the II-II line shown in FIG. 3 is a schematic perspective view showing a state in which the storage container shown in FIG. 1 is unfolded.

With reference to these figures, the storage container structure 1 includes an object to be stored 66, a watertight cylindrical storage body 51 for storing the object to be stored 66, and a storage body 51 (object to be stored 66). It is composed of a shock absorber 56 arranged below, and a storage container 11 arranged so as to cover the storage body 51 (object to be stored 66) and the shock absorber 56.

With reference to FIGS. 1 and 2, the storage container 11 is composed of a polyhedral-shaped enclosure 21 arranged so as to cover the outside of the storage body 51 (object to be stored 66). The surrounding body 21 is composed of a plurality of polygonal elastic bodies 23a to 23d constituting each surface of the outer surface thereof. The elastic body 23d is arranged below the shock absorber 56.

Here, the polyhedral shape of the surrounding body 21 of the storage container 11 is composed of a triangular pyramid shape. The triangular pyramid shape is the smallest number of faces among the polyhedral shapes. Therefore, since the surrounding body 21 is composed of the minimum number of four elastic bodies 23a to 23d, it is advantageous in terms of cost.

The elastic bodies 23a to 23d of the surrounding body 21 have airtightness, and are composed of, for example, a bag body 28 made of a rubber material and a gas 29 injected into the bag body 28. With this configuration, the bulk of the elastic bodies 23a to 23d before the injection of the gas is low, so that the storage container 11 can be easily stored and transported. Further, since the storage body 51 (object to be stored 66) is covered with the elastic bodies 23a to 23d of the surrounding body 21, it can be safely stored.

Further, the elastic bodies 23a to 23d of the surrounding body 21 are provided with pressure adjusting means 41a and 41b such as an air injection / discharging valve that can adjust the pressure of the gas 29 injected therein. With such a configuration, the elastic performance of the enclosure 21 of the storage container 11 can be adjusted, so that protection according to the characteristics of the stored object 66 such as weight and size can be achieved.

Here, the shock absorber 56 is configured to have an elastic function similar to the elastic bodies 23a to 23d, and also includes a pressure adjusting means 41c. With reference to FIG. 2, a shock absorber 56 is arranged below the storage body 51 (the object to be stored 66) in addition to the elastic body 23d. Further, the specific gravity of the shock absorber 56 is set to be larger than the specific gravity of other members in the storage container structure 1. Therefore, the position of the center of gravity of the storage container structure 1 is lowered toward the lower side. This makes it possible to drop the impact absorber 56 of the storage container structure 1 down, as in the case of dropping supplies from a helicopter to an isolated village in the event of a disaster, and the impact when touching the ground or the like is mitigated. Will be done.

With reference to FIG. 3, each of the elastic bodies 23a to 23d is configured to be expandable, and when the storage body 51 (the object to be stored 66) is surrounded as shown in FIG. 1, each of the facing bodies remains discontinuously. The sides 26a to 26f are connected by the connecting means 31a to 31j via the connecting holes 25a to 25g and the like. Here, the connecting means 31a to 31j are made of string-shaped bodies 34a to 34j to be hung on each side 26a to 26f, for example, like a rope. The string-shaped bodies 34a to 34j may be other than ropes.

Further, since each of the elastic bodies 23a to 23d is expandable, only the elastic body worn or the like due to use can be replaced with a new elastic body, which is advantageous in terms of cost.

With reference to FIG. 3, the storage container 11 is in an expanded state, and the elastic bodies 23a to 23c are arranged so as to face each side of the elastic body 23d, and the string-like body 34b which is the connecting means 31b to 31d. It is in a state of being connected by ~ 34d.

The storage body 51 (object to be stored 66) is placed on the upper surface of the shock absorber 56 arranged above the elastic body 23d.

In order to change from the expanded state shown in FIG. 3 to the used state shown in FIG. 1, each of the elastic bodies 23a to 23c is placed in the storage body 51 (contained object 66) in the direction of the solid arrow shown in FIG. Lift to cover the outside. Then, as shown in FIG. 2, the elastic bodies 23a to 23c are connected by passing the string-shaped body 34a, which is the connecting means 31a, through the connecting holes 25a to 25c formed in each of the elastic bodies 23a to 23c. ..

At the time of surrounding the storage body 51 (the stored object 66), the facing sides 26a to 26f remaining discontinuously are connected by the string-shaped bodies 34e to 34j which are the connecting means 31e to 31j. In the elastic bodies 23a and 23b, the sides 26a and 26e are connected by the string-shaped body 34e which is the connecting means 31e and the string-shaped body 34f which is the connecting means 31f. That is, the string-shaped body 34e, which is the connecting means 31e, is connected through the connecting hole 25d of the elastic body 23a and the connecting hole 25f of the elastic body 26b. The string-shaped body 34f, which is the connecting means 31f, is connected through the connecting hole 25e of the elastic body 23a and the connecting hole 25g of the elastic body 23b. In this way, when the string-shaped bodies 34e to 34j, which are the connecting means 31e to 31j, are connected, the string-shaped bodies 34e to 34j are loosened and connected even when the size of the storage body 51 (the object to be stored 66) is large. And the storage space can be adjusted, so rational storage is possible. Further, by connecting the connecting holes 25a to 25g previously formed on the sides 26a to 26f of the elastic bodies 23a to 23d with the connecting means 31a to 31j, it is necessary to set the optimum connecting point each time. As a result, the number of connecting points is reduced, and the storage operation is speeded up.

Next, the gas 29 is injected into the bag 28 via the pressure adjusting means 41a and 41b of the elastic bodies 23a to 23c, so that the state of use shown in FIG. 1 is obtained. In the drop preparation stage, for example, the storage container structure 1 may be suspended by passing a hanging hook (not shown) in addition to the string-shaped body 34a which is the connecting means 31a through the connecting holes 25a to 25c. Further, a parachute may be attached to the connecting holes 25a to 25g, and the storage container structure 1 may be dropped.

4A and 4B are schematic schematic views showing the locus of the center of gravity when the vehicle rolls over on a flat surface, FIG. 4 is a conventional storage container shown in FIG. 6, and FIG. 4 is a storage container shown in FIG. Is.

Here, for the sake of explanation, the center of gravity of the storage container is assumed to be in the center of the container.

As shown by the solid line with reference to (1) of FIG. 4, the storage container 71a is placed on a flat surface 61 such as the ground. A state in which the storage container 71a rolls over on the flat surface 61 in the direction of the arrow of the solid line to the storage container 71b shown by the alternate long and short dash line, the storage container 71c shown by the alternate long and short dash line, and the storage container 71d shown by the broken line. Is shown. At this time, the center of gravity of the storage container 71a draws a linear locus parallel to the flat surface 61 as shown by the solid line. That is, since the potential energy does not fluctuate during the rollover, the storage container 71a is likely to roll. Therefore, the ground contact state on the flat surface 61 of the storage container 71a is unstable.

As shown by the solid line with reference to (2) of FIG. 4, the storage container 11a of the storage container structure 1 is in a state of being placed on a flat surface 61 such as the ground. A state in which the storage container 11a rolls over on the flat surface 61 in the direction of the arrow of the solid line to the storage container 11b shown by the alternate long and short dash line, the storage container 11c shown by the alternate long and short dash line, and the storage container 11d shown by the broken line. Is shown. At this time, the center of gravity of the storage container 11a draws an arc-shaped locus so as to move up and down from the flat surface 61 as shown by the solid line. That is, since the potential energy fluctuates during the rollover, the storage container 11a is less likely to roll than the storage container 71a shown in FIG. 4 (1). Therefore, even when the container is dropped from above, the ground contact state on the flat surface 61 of the storage container 11a is stabilized so that the container stops at a position close to the drop location. Further, in the storage container 11a of the storage container structure 1, as shown in FIG. 1, the storage body 51 (object to be stored 66) is not shown on the ground or the like because the entire outer surface is covered with the surrounding body 21. Even if there is a convex portion, the impact is transmitted through the surrounding body 21, and the effect of impact mitigation is improved.

FIG. 5 is a schematic perspective view of the storage container shown in FIG. 1 in the liquid.

With reference to the figure, the storage container 11 of the storage container structure 1 is in a state of being floated in a liquid in the sea or the like. On the liquid surface 63, a part of the elastic bodies 23a to 23c of the surrounding body 21 in the storage container 11 shown by the solid line appears. On the other hand, a part of the storage container 11 shown by the broken line is located below the liquid level 63.

Since the elastic bodies 23a to 23d and the shock absorber 56 are composed of a bag body 28 having an airtightness in which a gas 29 is injected therein, they also exhibit watertightness and generate buoyancy by volume in the liquid. do.

The storage body 51 of the storage container 11 stores the stored object 66 inside the storage body 51 and has watertightness. Further, a fastener 53 having watertightness is formed on the upper surface of the storage body 51. As a result, the intrusion of water is prevented, so that the storage container 11 can be dropped at any place regardless of whether it is on the ground or in the liquid.

FIG. 9 is a schematic plan view schematically showing an elastic body constituting the enclosure of the storage container according to the second embodiment of the present invention, and FIG. 10 is a schematic plan view taken from the XX line shown in FIG. It is a schematic cross-sectional view seen.

The elastic body 23 of the storage container structure according to this embodiment further includes an internal pressure adjusting means 43 for preventing an increase in the internal pressure due to deformation. Since other configurations are basically the same as the configurations of the storage container structure of the first embodiment, the differences will be mainly described.

With reference to these figures, the elastic body 23 made of, for example, a rubber material of the surrounding body 21 according to this embodiment has a circular shape in a plan view. The bag body 28 of the elastic body 23 of the surrounding body 21 is formed by sealing the peripheral edges 45a and 45b of two identical circular sheet bodies with the same width in the radial direction with an adhesive or the like. .. In this case, different to such an adhesive or the like of the adhesive strength, the peripheral portion 45a of the bag 28, the adhesive force F ₂ of the second adhesive layer 47 corresponding to a portion of the 45b, the first adhesive layer corresponding to the other portion 46, the internal pressure adjusting means 43 of the elastic body 23 is formed so as to be smaller than the _{adhesive force F 1} at the portion having the same circumferential length as the second adhesive layer 47 _{(F 2} <F _1). The reason for this configuration will be described later.

Further, the elastic body 23 is provided with the same pressure adjusting means 41 as the elastic body of the first embodiment. By injecting the gas 29 into the bag body 28 of the elastic body 23 via the pressure adjusting means 41, the state of use as shown in FIG. 10 is obtained.

FIG. 11 is a schematic schematic diagram showing the state of the elastic body and the storage body after dropping of the storage container containing the stored object according to the second embodiment of the present invention, and FIG. 11 (1) is a state immediately after dropping. (2) is a diagram showing a state immediately after a collision with the ground, and (3) is a diagram showing a state after a certain time has elapsed from the collision with the ground.

In FIG. 11, in order to make it easy to understand the deformation process of the elastic body, only the storage body 51 in which the stored object is stored and the elastic body 23 arranged in the lower part of the storage body 51 are shown instead of the entire storage container structure 1. ing.

With reference to (1) in the figure, first, the storage container structure 1 is dropped from a helicopter or the like. _{At this time, the opening force (P 1} × (area) A) that tries to open the seal by _{the internal pressure P 1} of the elastic body 23, _{the adhesive force F 1} of the first adhesive layer 46, and the adhesion of the second adhesive layer 47. The force F ₂ has a relationship of (P ₁ × A) <F ₂ <F ₁ , and the gas remains sealed. The area A refers to a fixed value based on the shape of the elastic body for converting the opening force applied to the sealing portion by the internal pressure P _1.

Next, referring to (2) in the figure, when the dropped storage container structure 1 collides with a flat surface 61 such as the ground, a force G applied by the fall and a corresponding reaction force R are applied respectively. become. Then, the elastic body 23 is compressed from above and below by the force G applied by the fall and the corresponding reaction force R. As a result, the elastic body 23 is compressed from, for example, the shape represented by the broken line to the shape represented by the solid line according to the compressive force. Then, since the volume of the elastic body 23 is temporarily reduced, the gas inside of the elastic body 23 is compressed, the internal pressure P ₂ of the elastic body 23 is increased.

At this time, the elastic body 23 is _{sealed so that the adhesive force F 2 of the second adhesive layer 47 is smaller than the adhesive force F 1} of the first adhesive layer 46, _{so that the internal pressure P 2} of the elastic body 23 is increased. When the opening force (P ₂ × A) based on the above exceeds _{the adhesive force F 2} of the second adhesive layer 47 _{(F 2} <(P ₂ × A) <F ₁ ), the sealing of the second adhesive layer 47 is the internal pressure. It loses its size and is released. Then, the gas gradually flows out to the outside through the second adhesive layer 47 whose sealing is opened, so that the internal pressure P ₂ of the elastic body 23 gradually begins to drop. In this case, under normal use environment, the internal pressure P ₂ from that the opening force (P ₂ × A) begins to drop before exceeding the adhesive force F ₁ of the first adhesive layer 46, the opening force (P ₂ × a) it is not exceed the adhesive force F ₁ of the first adhesive layer 46, first adhesive layer 46 remains adhered without being opened.

Therefore, since the repulsive force of the elastic body at the time of collision does not increase, damage to the stored object is suppressed. Further, since the sealing of the second adhesive layer 47 is released as the internal pressure of the elastic body 23 increases, the protective function of the elastic body 23 can be adjusted.

Further, referring to (3) in the figure, the gas continues to flow out of the elastic body 23 through the opened second adhesive layer 47, _{and the outflow stops when the internal pressure P 3} becomes equal to the external pressure (P). ₃ × A = 0 <F ₂ <F ₁ ).

Then, the elastic body 23 finally shrinks to about the thickness of the material or the like, but as described above, the gas inside gradually flows out, so that the elastic body 23 has a certain protective function. , Damage to the stored object stored in the storage body 51 is suppressed.

FIG. 12 is a schematic schematic diagram showing a state of an elastic body and a storage body after dropping of a storage container containing an object to be stored according to a third embodiment of the present invention, and FIG. 12 (1) is a state immediately after dropping. (2) is a diagram showing a state immediately after a collision with the ground, and (3) is a diagram showing a state after a certain time has elapsed from the collision with the ground.

The elastic body 23 of the storage container structure 1 of this embodiment is provided with the internal pressure adjusting means 43 different from that of the second embodiment. Since other configurations are basically the same as the configurations of the storage container structure of the first embodiment, the differences will be mainly described.

In FIG. 12, as in FIG. 11, in order to make it easy to understand the deformation process of the elastic body, only the storage body 51 and the elastic body 23 arranged under the storage body 51 are shown instead of the entire storage container structure 1. There is.

With reference to (1) in the figure, specifically, the elastic body 23 having the same structure as the elastic body of the first embodiment is further provided with a relief valve 49. The relief valve 49 operates when the internal pressure P ₁ of the elastic body 23 exceeds a certain value (the set pressure P of the relief valve 49) so that the valve opens instantly and the gas inside the elastic body 23 is discharged to the outside. It is set.

In order to make the storage container structure 1 usable, first, gas is injected into the elastic body 23 via the pressure adjusting means 41. Then, the internal internal pressure P ₁ rises, and the elastic body 23 expands. When the gas is continuously injected, the internal pressure P ₁ of the elastic body 23 rises further, and when the set pressure P of the relief valve 49 is reached (P ₁ = P), the valve of the relief valve 49 opens and a part of the gas is released. It will be discharged to the outside. At that point, when the injection of gas is stopped and the internal pressure of the elastic body 23 falls below the set pressure P of the relief valve 49 (P ₁ <P), the valve of the relief valve 49 closes and the elastic body 23 is sealed. .. As described above, since it is not necessary to set the gas injection amount in advance, the work efficiency in preparation is improved.

Such a storage container structure 1 is dropped from a helicopter or the like. At this time, the internal pressure P ₁ of the elastic body 23 and the set pressure P of the relief valve 49 have a relationship of _{P 1 <P.}

Next, referring to (2) in the figure, when the dropped storage container structure 1 collides, a force G applied by dropping and a corresponding reaction force R are applied respectively. Then, the elastic body 23 is compressed from above and below by the force G applied by the fall and the corresponding reaction force R. As a result, the elastic body 23 is compressed from, for example, the shape represented by the broken line to the shape represented by the solid line according to the compressive force. Then, since the volume of the elastic body 23 is temporarily reduced, the gas inside the elastic body 23 is compressed, and the internal pressure P ₁ of the elastic body 23 rises to P ₂ .

At this time, at the moment when the internal pressure P ₂ reaches the value of the set pressure P of the relief valve 49 (P ₂ = P), the valve of the relief valve 49 operates. Then, since the gas is gradually discharged to the outside through the relief valve 49, the internal pressure P ₂ does not exceed the set pressure P.

Therefore, since the repulsive force of the elastic body 23 at the time of collision does not increase, damage to the stored object stored in the storage body 51 is suppressed.

Furthermore, with reference to (3) in the figure, as described above, since the valve of the elastic body 23 of the pressure P ₃ is relief valve 49 set pressure P to below the relief valve 49 closes, discharge of the gas ceased ( P ₃ <P). That is, the elastic body 23, unlike the second embodiment, to remain in the form of gas therein to maintain the internal pressure P _3, so that a constant elastic force is maintained.
