[0003]

By the way, the following problems have been pointed out in such a conventional example. That is, first, in the conventional cushioning member 5 mounting structure, the pallet 1
Since the cushioning material 5 is interposed between the cushioning material 5 and the load 3, if the amount of the cushioning material 5 crushed by soft landing or the like is small, the load 3 is not crushed at the time of landing and the pallet is inserted through the cushioning material 5. There is a situation in which the pallet 1 does not reach the pallet 1 as expected because the wheels 6 of the vehicle 2, which is the mounted object 3, remain on the pallet 1 as expected. So after landing,
Difficulty of complicated and troublesome removal and dismantling work of the mounting object 3 such as jacking up the mounting object 3 such as the vehicle 2 from the top of the pallet 1 and extracting the uncrushed cushioning material 5 from under the wheel 6. was there. Secondly, it has been pointed out that the conventional mounting structure has a problem in that the mounted object 3 cannot be used or deployed quickly after landing and landing. For example, after landing and landing, the vehicle 2, which is the mounted object 3, cannot be immediately started, which hinders quick airborne action.

Third, in the conventional mounting structure, the pallet 1
Since the cushioning material 5 is fixedly interposed between the mounting material 3 and the loading object 3 and the overall height is high, there is a spatial allowance for the restricted height inside the aircraft when it is mounted on the aircraft. Without
It was pointed out that it is cramped and may interfere with the on-board work. Fourthly, in the conventional mounting structure, since the cushioning material 5 is interposed between the pallet 1 and the mounted object 3 and the cushioning material 5 does not exist under the pallet 1, the drop impact at the time of landing is achieved. As a result, there is a problem that the pallet 1 is easily damaged.

In view of such circumstances, the present invention has been made to solve the problems of the above-mentioned conventional example, and the cushioning material can be displaced between a preparation position near the end and a cushioning position under the pallet. In addition, the cushioning material is held at the preparation position by the holding material inside the machine, displaced in the air by the tensioning means equipped with the wire, and positioned by the positioning means at the cushioning position.

At the same time, thirdly, the cushioning material has a limit height when mounted on an aircraft, fourthly, the pallet is prevented from being damaged at the time of landing, and fifthly, the cushioning material is realized by a simple structure. The purpose is to propose a mounting structure for.

[0006]

The technical means of the present invention for achieving this object are as follows. That is, the mounting structure of the cushioning material is such that a mounted object such as a vehicle directly mounted on a pallet with a parachute is dropped from the aircraft into the air with a parachute, and the mounted object is passed through the pallet in the air during the fall. It is used for landing by hanging under the opened parachute, and protects the mounted object from a drop impact at the time of landing. Further, it has the following cushioning material, holding material, pulling means, positioning means and the like. That is, in a structure such as being held in a preparation position at the end of the loaded object in the aircraft or the like, and in a buffer position on the bottom surface side of the pallet in the middle of falling, it is more likely to be crushed by a drop impact at the time of landing. A cushioning material, a holding material interposed between the cushioning material in the preparation position and the mounted object or pallet, and holding the cushioning material in the preparation position, and the cushioning material in the preparation position. On the other hand, a wire connected through the bottom surface of the pallet is provided, and it is possible to apply a tensile force to the cushioning material with the wire in the air in the middle of falling, and release the holding by the holding material, Pulling means for wrapping the material from the preparation position to the buffering position and holding it, and interposed between the buffering material and the pallet at the buffering position, the buffering material is stably placed at the buffering position. Positioning means for positioning, And composed.

In this way, the mounted object 3 such as the vehicle 2 is
The cushioning material 18 is positioned and held at the cushioning position B under the pallet 1 and descends in the air to land on the ground. Therefore, the mounted object 3 is protected from the drop impact by the cushioning material 18 being crushed by the drop impact at the time of landing and the drop impact being absorbed. Then, after such landing and landing, the mounted object 3 such as the vehicle 2 is removed from the pallet 1 and released to be started, used and deployed. Now, according to the mounting structure of the cushioning material 18, the following first, second, third, fourth and fifth are provided.

First of all, since the mounted object 3 such as the vehicle 2 is landed on the pallet 1 in a state of being directly in contact with the pallet 1, the pallet 1 is landed on the pallet 1 at the time of landing like the conventional example of this kind shown in FIG. It does not occur that the wheels 6 of the vehicle 2 float up and the wheels 6 of the vehicle 2 do not reach the pallet 1, for example. Therefore, the mounted object 3 such as the vehicle 2 is jacked up and the cushioning material 18 after landing.
It can be easily and easily removed from the pallet 1 and released without the need for work such as removing. Secondly, after landing and landing there, the mounted object 3 such as the vehicle 2 can be immediately started, used and deployed.

Thirdly, the cushioning material 18 is vertically held at the preparation position A near the rear end of the mounting object 3 when it is mounted on the aircraft 7. Therefore, as compared with the conventional example of this type shown in FIG. 8, the overall height of the mounting object 3 and the pallet 1 is reduced, and a spatial allowance is generated with respect to the height limit inside the machine. Fourthly, since the cushioning material 18 is positioned and held at the cushioning position B below the pallet 1 at the time of landing, the pallet 1 is also protected from the drop impact at the time of landing. Fifthly, in addition to these, the conventional mount 2, such as the vehicle 2, the pallet 1, the parachute such as the main umbrella 4, etc. can be used as they are, and the predetermined cushioning material 18, holding material 19, wire 20, etc. can be pulled. It suffices to provide the means, the positioning means 21, etc., and is realized by a simple structure.

[0024]
