Abstract

PURPOSE:To prevent the loaded equipments from being damaged, even when a destination spot is in an irregular or tilt shape further with a large shock load additionally acting, by forming a shock absorbing material by a shock absorbing material main unit consisting of paper honeycomb material of predetermined compression strength and a waterproof sheet material coating the main unit with a vacuum packing. CONSTITUTION:At the moment when a shock absorbing material 11 is grounded in its bottom surface, a paper honeycomb material 13, forming a shock absorbing material main unit 12, is given a shock load compressing the honeycomb material 13 in the axial direction of a cell 13a. When this shock load is applied, compression stress is generated in the honeycomb material 13, but it functions not as the shock absorbing material before the stress reaches a fixed value, that is, the compression strength of the honeycomb material 13, and the honeycomb material 13 is given the shock load transmitted being left as is through a moving shelter 1 to equipments loaded. Accordingly, the shock load is applied to the equipments, but because a shock value is further smaller than the compression strength of the honeycomb material 13 forming the main unit 12 set to a smaller value than a permissible value G of the equipment, it is prevented from being damaged.

Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention is applicable to mobile box-shaped objects such as mobile shelters, containers, etc., which are transported via transportation means. f4 A moving box that protects the equipment, luggage, etc. loaded inside by reducing and absorbing the buffering load applied to the moving box-like structure when the body is lowered from the transportation means to the ground at the destination. The present invention relates to a shock absorber for a shaped structure.

“Prior art” and “Problems to be solved by the invention” Box-like structures for transportation such as mobile shelters and containers (hereinafter referred to as
(simply referred to as "mobile shelters, etc.") are generally transported to their destinations by means of transportation such as trucks or other vehicles. However, even if the destination is a place where it is extremely difficult to transport by vehicle, such as a remote mountainous area, or even if it is possible to transport by vehicle without any difficulty, depending on the destination, vehicle transport may take a long time. , When transportation is extremely urgent, a helicopter is used for suspended transportation.

In the case of suspended transportation by helicopter, at the destination,
When lowering a suspended mobile shelter, etc. to the ground, the suspension wires are normally unrolled very slowly, so if the equipment, cargo, etc. loaded inside are ordinary items, Although there is little chance of damage, for example, in the case of a mobile communication shelter loaded with high-precision electronic equipment, communication equipment, etc., the permissible G value of the loaded equipment may be affected when the equipment is grounded. If an impact load that even slightly exceeds the above is applied to a mobile shelter, etc., there is a risk that these devices will be damaged. l! It was equipped with side thrusters to prevent accidents.

However, when using such legs to prevent damage to equipment loaded into a mobile shelter, etc., the following problems have been pointed out.

First, if the destination is flat and a movable shelter is lowered perpendicular to it, the oleo model works perfectly and the impact load applied to the 'MWI leg upon touchdown is completely absorbed by the #li[r leg. However, if the destination is uneven or sloped, even if the conditions are within the allowable range for lowering the movable shelter, etc., the shock absorbing bullet will absorb the instant it hits the ground. For example, impact loads may be applied diagonally, etc. In such cases, the buffer legs may not function for 1 minute, causing damage to equipment, and was sometimes damaged.

Secondly, even though such shock absorbing legs are used very infrequently, because they are hydraulic mechanisms, they must be inspected and kept on hand at all times, making the work extremely troublesome.

Thirdly, since the structure of such buffer legs is complicated,
It was expensive.

Such problems have been pointed out in conventional 1iJ2 impact devices such as VJ and mobile shelters using street legs.

Therefore, in order to solve the problems of shock absorbers such as movable shelters using conventional shock absorber legs, the SN that constitutes the shock absorber
The street material is made of honeycomb materials each having a predetermined compressive strength, and is formed into a pillar shape with an appropriate cross-sectional area and an appropriate height in order to support the lower corner of a movable shelter, etc. with its cell end surface. , These MflI materials can be attached to the lower part of each corner using a mounting belt or the like, either directly or via a mounting member, etc., depending on the structure of the mounting part of the mobile shelter, etc. that is used. A shock absorber is provided.

In a shock absorbing device such as a movable shelter having such a configuration, when the MR device is used, when the movable shelter etc. is not attached with each buffer material constituting the shock absorbing device, the movable shelter etc. has a honeycomb shape at the lower part of each corner. It is supported by a cushioning material made of material.

By the way, when an impact load is applied to the honeycomb material in the direction of its cell axis to compress the honeycomb material,
Compressive stress is generated in the honeycomb material, and when this stress reaches a certain level (compressive strength of the honeycomb material, that is, the compressive strength of the cell walls constituting the honeycomb material), the cell walls begin to buckle. -dan,
After the cell walls begin to buckle, the cell walls continue to buckle with a substantially constant compressive strength that is much smaller than the compressive strength of the honeycomb material before the cell walls begin to buckle. It has the characteristic that it absorbs the impact load applied to the honeycomb material due to the buckling of the walls, and that the absorption effect continues until about 75% of the length in the cell axis direction is buckled.

Therefore, the degree of shock load absorption due to the buckling of the cell walls is constant, and since the shock load is absorbed due to the permanent strain caused by the buckling of the cell walls, no recoil action occurs. In addition, buckling of cell walls progresses under an impact load that is much smaller than the impact load applied until the honeycomb material reaches its compressive strength. Never.

Therefore, when using a shock absorber when transporting a mobile shelter, etc., it is mainly limited to cases where the loaded equipment is of high precision and its allowable G value is small. must be formed of a honeycomb material having a predetermined compressive strength, that is, a compressive strength that is smaller than the allowable G value of the equipment, and
The cushioning material made of honeycomb material is disposable after each use, and honeycomb material with low compressive strength is easy to mold.

In addition, because it is inexpensive, a vapor honeycomb material with a predetermined compressive strength is used, and its height is as follows.
When the mobile shelter, etc. is lowered at an appropriate height, that is, the condition of the destination is uneven or sloped, and the condition is at the limit where lowering the mobile shelter, etc. is permissible. Also, while buckling of the cell walls of the vapor honeycomb material that forms the buffer material that is first grounded continues, buckling of the vapor honeycomb material that forms the sealing material that is not grounded last begins. It is formed to a height that can also be
The cross-sectional area is formed to have a cross-sectional area that allows the cell end surface to support the lower surface of the corner of a movable shelter or the like.

Therefore, when attaching the M1 # equipment and lowering a mobile shelter, etc. that has been transported to the air over the destination and lowered it to the ground, even if the destination is not flat, the impact load is first applied to the lower surface of the cushioning material that first touched the ground. is applied, and when this load reaches the compressive strength of the vapor honeycomb material forming the buffer material, the cell walls begin to buckle, and thereafter, the impact load is absorbed by the cell walls' buckling.

Then, when the buckling of the vapor honeycomb material forming the cushioning material that first touched the ground has progressed to a certain degree, the buckling of the vapor honeycomb material forming the M impact that touched the ground begins, and in this way, , 4! While the shock absorber is grounded and the vapor honeycomb material that forms the first grounded buffer material continues to buckle, the vapor honeycomb material that forms the last grounded gffl material begins to buckle. The impact load applied to the 1#X shock absorber is absorbed by the buckling of the vapor honeycomb material forming each shock absorber.

Therefore, equipment loaded into mobile shelters, etc.
Initially, an impact load is applied, but the value of i zero load is R”
Since the G value is smaller than the allowable G value for Class R, the loaded equipment will not be damaged.

As described above, in the conventional shock absorbing equipment such as a mobile shelter having such a configuration, the y! Since the street bombing material is made of vapor honeycomb material, firstly, the destination where the movable shelter etc. is dropped is not flat, for example, the destination is uneven or sloped. The condition is
Even when a mobile shelter or the like is lowered to a place at the limit where it is permissible to lower it, it can fully perform its function.

Second, it is easy to handle, as it does not require constant inspection or maintenance.

Thirdly, the M shock absorber, which constitutes the main part of the shock absorber, can be formed from an inexpensive vapor honeycomb material, so the shock absorber is extremely inexpensive.

Although it has characteristics such as 1! Since the reinforcement material is made of vapor honeycomb material, the following problems have been pointed out.

First, vapor honeycomb materials have the property of being extremely susceptible to moisture absorption, and when moisture is absorbed, the quality deteriorates, for example, the compressive strength value decreases, and the degree of deterioration changes depending on the degree of moisture absorption. In some cases, there is a concern that the cushioning material may not fulfill its m1tll function, so it is troublesome to select a storage location for the cushioning material that is used infrequently and to handle it during transportation.

Second, if it is raining during use, it is necessary to cover the M cushioning material with a waterproof sheet to prevent it from getting wet. If the cushioning material is made thicker than necessary, the compressive strength and other performance of the cushioning material may change, causing damage to the loaded equipment, so the covering work must be done carefully. It had to be carried out according to established standards, and therefore the work was troublesome and required a lot of man-hours.

Thirdly, cjAf, handling during transportation etc. is perfect, and
Even if the weather at the time of use is sunny with low humidity, if the destination is a place with puddles or a wetland, the effective stroke will be impaired. etc., there was a risk that the function of the cushioning material would deteriorate and damage the equipment.

This problem has been pointed out in conventional shock absorbing devices such as movable shelters made of buffer materials made of vapor honeycomb material.

In view of these circumstances, the present invention was made to solve the problems of the conventional example described above.
For example, when transporting by suspended transport using a helicopter, the destination is uneven or sloped, and the conditions are at the limit where it is permissible to lower a mobile shelter, etc. Even if a large shock load is applied to the shock absorber at a time, it can absorb the shock load and completely prevent the loaded equipment from being damaged. Not only does it require no troublesome work such as maintenance, it is easy to handle, and it is inexpensive. 2JR such as deterioration of quality does not occur at all,
It is extremely easy to handle during storage and transportation, and there is no need for complicated covering work even when using it in the rain.
Moreover, even if there is a puddle of water or if the ball is dropped at a wetland-like destination, the effective stroke will not be impaired or its performance will be reduced, and it can fully fulfill its 'R' ability. The purpose is to propose a shock absorbing device such as a mobile shelter.

"Means for Solving the Problems" The present invention has been made to achieve the above object, and the technical solutions thereof are as follows.

This shock absorbing device is a shock absorbing device for mitigating and absorbing an impact load applied to a movable shelter etc. transported via a transportation means when the movable shelter etc. is lowered from the transportation means to the ground. The cushioning material that constitutes the device 411 consists of a cushioning material body made of vapor honeycomb material having a predetermined compressive strength, and a waterproof sheet material covering the cushioning material body by vacuum packing. , is formed into a columnar shape with an appropriate height and a cross-sectional area capable of supporting the lower corner portion of the movable shelter etc. by the cell end face.

Then, a cushioning material having such a configuration is placed in a predetermined positional relationship at the lower part of each corner of the movable shelter, etc., via appropriate attachment means! 7 can be installed respectively.

"Medical Use" Since the present invention consists of the above-mentioned means, it functions as follows. That is, for example, when transporting a mobile shelter, etc. loaded with high-precision equipment, etc. by suspended transport using a helicopter, each M new material constituting the device is attached to the mobile shelter, etc. via an appropriate attachment means. When the movable shelter, etc. is installed in a predetermined positional relationship at the lower four corners of the
From the allowable G value of equipment loaded into mobile shelters, etc.,
A vapor honeycomb material with a small compressive strength is used, and it has a cross-sectional area that allows the lower part of the corner to be supported by the cell end face. Forming the main body of the M product that does not touch the ground first even when the movable shelter, etc. is lowered in a place where the movable shelter, etc. is at the limit where it is permissible to lower the movable shelter, etc. While the buckling of the cell walls of the vapor honeycomb material continues to progress, the vIWi material body that finally touched the ground has a height that allows the cell walls of the vapor honeycomb material to begin buckling. Since the main body of the cushioning material formed in the shape of a column is supported by the cushioning material made by vacuum packing and covered with a waterproof sheet material, firstly, the destination where the movable shelter etc. is dropped is not flat. Even if the destination is uneven or sloped, and the condition is at the limit where it is permissible to lower a mobile shelter, etc., it can still perform its function. As a result, the eight loaded aircraft will not be damaged.

Second, there is no need to constantly inspect and adjust the fiffi.
Its handling is easy.

Thirdly, since the main body of the shock absorbing material, which occupies the main part of the M new device, is formed of low-grade vapor honeycomb material, the shock absorbing device is extremely inexpensive.

Furthermore, in particular, since the cushioning material is made of MWI material made of vapor honeycomb material, the rod body is vacuum packed and covered with a waterproof sheet material, so fourthly, if it is stored for a long time in a general safe etc. , or 1. Even when transported by normal truck transportation, the cushioning material does not absorb moisture and its quality deteriorates, and therefore, it is extremely easy to store and handle during transportation. It is.

Fifth, even if it is used in the rain, there is no need to cover with a complicated tarpaulin sheet, which was necessary each time, and the compressive strength and other problems caused by covering with a tarpaulin sheet are No problems such as changes in performance will occur.

Sixth, even if the destination is in a place where there is a puddle of water or a wetland, performance may deteriorate, for example, the effective stroke of the cushioning material will be impaired. There will never be a situation where you are unable to fulfill your full potential.

Seventh, the inside of the cushioning material is in a vacuum state, and the pressure is lower than the outside pressure, so when the vapor honeycomb material that forms the main body of the cushioning material buckles, or when it touches the ground, the cushioning material is exposed to stones on the ground. Even if the waterproof sheet material is torn due to a collision with a protrusion such as the 6. Embodiment The present invention will be described below based on an embodiment shown in the drawings.

Figure 1 is a partially cutaway perspective view of 1flWi forest, Figure 2 is
FIG. 3 is a perspective explanatory view showing a state in which each of the cushioning materials constituting the shock absorbing device is attached to the movable shelter, and FIG. 3 is a side view of the main part of FIG. 2.

First, an outline of the mobile shelter will be explained.

In the figure, reference numeral 1 denotes a movable shelter, and this movable shelter 1 has a box shape, and has a frame frame 2 provided at the top, bottom, left and right, and front and rear edges, side walls 3, a top wall 4, and a bottom wall 5. End side walls 6 are fixedly attached to the front and rear end surfaces, respectively. In the illustrated example of the mobile shelter 1, an entrance/exit (not shown) is provided in one end side wall 6, and a slanted door 7 opens and closes the entrance/exit.
is installed.

The mobile shelter 1 is loaded with 5 devices (not shown), such as high-precision electronic devices and communication devices.

The mobile shelter 1 is roughly like this.

Next, the cushioning material constituting the shock absorbing device will be explained.

Reference numeral 11 denotes the M product constituting the shock absorber 10, and this [1
The materials 11 are as follows. 12 is the main body of the buffer material of Ni-gai Shinzai 1, and this l! impact body 1
2 is formed of a vapor honeycomb material 13 having a predetermined compressive strength, that is, a compressive strength whose value is smaller than the allowable G value of the equipment (not shown) loaded into the mobile shelter 1.

The vapor honeycomb material 13 forming this cushioning material main body 12 has the cell axis of each cell 13a located along the vertical direction, and supports the lower surface of the corner of the movable shelter 1 by the end surface of the cell 13a. When a mobile shelter 1 having a cross-sectional area that allows for Even if the condition is uneven or sloped, and the condition is at the limit where it is permissible to lower the movable shelter 1, the vapor forming the shock absorbing material main body 12 will be While the buckling of the cell walls 13b of the honeycomb material 13 continues, the cushioning material 11 touches the ground after a.
It is formed into a columnar shape with a substantially square cross section and has a height at which buckling of the cells u13b of the vapor honeycomb material 13 forming the buffer material body 12 of is formed.

In addition, on the open end surface of the cell 13a of the vapor honeycomb $413 that forms this VI street new material body 12, a part of the cell wall 13b near the cell end surface is formed, for example, during vacuum bag packaging or installation, which will be described later. A surface protection sheet 14 made of kraft paper is attached to prevent deformation, damage, and loss of gffffn performance.The cushioning material main body 12 has a columnar shape with a substantially square cross section. The cross section is not limited to, and the cross section may be rectangular, approximately right triangular in cross section, or columnar such as a fan shape with two sides at approximately right angles.

The vapor honeycomb material 13 forming the M member main body 12 with the surface protection sheet 14 attached to the open end face of the cells 13a is covered by vacuum bag packaging with a waterproof sheet material 15 such as a plastic sheet.

The cushioning material 11 constituting the I-shock device 10 is constructed as described above.

Next, the means for attaching the cushioning material and the like will be explained.

In FIGS. 2 and 3, 31 is an upper mounting bracket, and 32 is a lower mounting bracket. Each of these mounting brackets 31 and 32 has a hook 33 on the tip of the mounting belt 30, which will be described later. A stop hole (not shown) is drilled therein.

In the illustrated example, when attaching the cushioning material 11 to the movable shelter 1, the upper mounting bracket 31 attaches the cushioning material 11 to the lower surface of the corner of the movable shelter 1.
The movable shelter is arranged so that the end surfaces of the cells 13a of the cushioning material main body 12 face each other, and the substantially orthogonal outer surfaces of the cushioning material 11 are brought into contact with the outer surfaces of the side walls 3 and end side walls 6 at the corners, respectively, and the road surface. 1, the side wall 3 and end fIJ in the −L direction of the cushioning material 11 are in contact with the lower surface of the corner of the cushioning material 11. Two of each are arranged on the I wall 6 at a predetermined interval.

In addition, the lower mounting bracket 32 is attached to the movable shelter 1 at a predetermined distance from the inner edge of the upper surface of the buffer material 11 when the buffer material 11 is in contact with the lower surface of the corner of the movable shelter 1 in the above-mentioned positional relationship. They are respectively disposed at locations corresponding to the respective upper mounting brackets 31 on the lower surface.

In addition, 30 is a mounting belt, 30a is a fixed side belt of the mounting belt 30, 30b is an adjustment side belt of the mounting belt 30,
34 is a buckle attached to the end of the stationary belt 30a.

Therefore, y! When using the clamping device 30 and attaching the new street material to the mobile shelter 1, first, the hook 33 is attached to the tip of the adjustment belt 30b.
are respectively hung in the latching holes (not shown) of the lower mounting brackets 32, and then, after positioning the cushioning material 11 on the lower surface of the corner of the movable shelter l in the above-mentioned positional relationship, this state is While maintaining the attachment belt 30 along the outer peripheral surface of the N member 11, the hook 33 attached to the tip of the fixed side belt 30a is attached to the upper part arranged in a positional relationship corresponding to the lower attachment bracket 32. They are respectively hooked into the hooking holes (not shown) of the mounting bracket 31, and finally, the end of the adjustment side belt 30b that is locked to the buckle 34 is adjusted to tighten the cushioning material 11 with the mounting belt 30. As a result, the MWI material 11 is attached to a predetermined position of the mobile shelter 1.

Note that the means for attaching the cushioning material 11 is not limited to the above-mentioned embodiments, and since the cushioning material 11 is extremely lightweight, it may be attached using an adhesive tape or the like.

The means for attaching the cushioning material 11 is as described above.

The above is the explanation of the configuration, etc.

Hereinafter, the vital movement etc. will be explained.

Now 1. When transporting the mobile shelter 1 to a destination by, for example, suspended transport using a helicopter, first, cushioning material 1 is placed at the bottom of each of the four corners of the mobile shelter 1.
1 in the specified positional relationship.

The movable shelter 1 to which the cushioning material 11 is attached has #! 1. It is supported by new town material 1.

The mobile shelter 1 to which the ffl street device 10 is attached in such a state is lowered and lowered by a helicopter and transported to the LI destination.

The mobile shelter 1 that has been transported to the sky above the destination is lowered to the destination by letting out the suspended wires.

Therefore, firstly, at the moment when the bottom surface of the cushioning material 11 touches the ground, M
Forming the member body 121. In the vapor honeycomb material 13, the vapor honeycomb material 13 is
An impact load is applied that acts to compress the When this impact load is applied, compressive stress is generated in the vapor honeycomb material 13, but until this stress reaches a certain level, that is, the compressive strength of the vapor honeycomb material 13, the vapor honeycomb material 13 is #yi The impact material does not function, and the impact load applied to the vapor honeycomb material 13 is transferred to the movable shelter 1 as it is.
The information is transmitted to the loaded equipment via the therefore,
This impact load is applied to the equipment, but the value of this impact load is set to a value smaller than the allowable G value of the loaded equipment. Since this value is even smaller than the value of compressive strength, the transmitted impact load will not damage the equipment. However, when the stress generated in the vapor honeycomb material 13 forming the buffer material main body 12 reaches compressive strength, the cell walls 13b begin to buckle. And -dan, cell wall 1
3b begins to buckle, the cell walls 13b proceed with a compressive strength that is considerably smaller than the compressive strength of the vapor honeycomb material 13 before the cell walls 13b begin to buckle, and the cell walls 13b buckle. Since the impact load applied to the buffer material 11 due to the bending is absorbed, no impact load is applied to the loaded equipment after the cell wall 13b begins to buckle.

Furthermore, even if the destination where the mobile shelter 1 is lowered is uneven or sloped, and the condition is at the limit where the mobile shelter 1 is allowed to be lowered,
The height of the cushioning material main body 12 is such that the cell wall 13 of the vapor honeycomb material 13 forming the #1 street lumber 12 does not initially touch the ground.
While the buckling of b continues to progress, the cells of the vapor honeycomb material 13 that form the cushioning material body 12 finally touch the ground! Since the height is set at a level where i3b can begin to buckle, even when lowered into such a location, no shock load exceeding the allowable G value will be applied to the loaded equipment.

Second, the #1 cushioning material 11 constituting the shock absorbing device 10 includes a cushioning material main body 12 formed of a vapor honeycomb material 13, and a structure in which the cushioning material main body 12 is not covered by vacuum packing with a waterproof sheet material 15. It is easy to handle, as there is no need for constant inspection or maintenance.

Thirdly, the cushioning material main body 12 occupies the main part of the cushioning device 10.
Since the shock absorber 10 can be formed from a low-temperature vapor honeycomb material, the shock absorber 10 is extremely inexpensive.

Furthermore, in particular, since the impact 11 is composed of an MfE material main rod body 12 formed of a vapor honeycomb material 13 and covered with a waterproof sheet material 15 by vacuum packing, fourthly, it is used less frequently. Even when the cushioning material 11 is stored for a long period of time in a general *m etc. or transported by normal truck transportation, the vapor honeycomb material 13 forming the II impact body 12 absorbs moisture. , there will be no situation where the quality deteriorates,
Therefore, it is extremely easy to store and handle during transportation.

Fifth, even if it is used in rainy weather, there is no need for the frequent covering work with a tarpaulin sheet, which was necessary each time, and the compressive strength etc. due to the covering with a tarpaulin sheet is reduced. No problems such as changes in performance will occur.

Sixth, even if the state of the destination is a place where there is a puddle or a wetland, for example, #1
There will be no situation where the effective stroke of the vapor honeycomb material 13 forming the shock absorbing material 12 is impaired or the performance is degraded and the shock absorbing material 11 is unable to fully perform its function.

Seventhly, the inside of the buffer material 11 is in a vacuum state, and the pressure is lower than the outside pressure, so when the vapor honeycomb material 13 forming the llj material main rod body 12 buckles or when it touches the ground, the buffer material 11 is in a vacuum state. 11 collides with a protrusion such as a stone on the ground, and even if part of the waterproof sheet material 15 is torn, the outside air that entered through the torn part will cause the vapor honeycomb material 13 to buckle. At the same time, since the vapor is discharged from the broken part again, no air pack effect occurs, and therefore, no change occurs in the compressive strength or the like of the vapor honeycomb material 13.

The above is the explanation of the operation, etc.

"others" Next, another embodiment of the shock absorber 10 will be described.

FIG. 4 is a perspective view showing the mutual attachment positional relationship between the g-side material and the side protection member attached to this yI street.

In this embodiment, [I! I
A side protection member 20 is attached to protect the lower end of the wall 3 and the end side wall 6.

The side protection member 20 attached to the M product 11 is as follows. The side protection member main body 21 of this side protection member 20 is made of a vapor honeycomb material 2 having the same compressive strength as the vapor honeycomb material 13 forming the buffer material tIF, 12.
2, the cell axis of each cell 22a is located along the horizontal direction, and its height is higher than the height of the V11 material 11, and the length in the width direction is Regarding the size, one of the four-part protective member main body 21
However, the end face of the cell 13a is formed to have a length equal to the length of one side of the v1 timber body 12, which is formed into a substantially square shape,
Further, the other side protection member main body 21 is formed to have a longer length in the width direction than the width direction of the other four-part protection member main body 21 by the thickness of the side protection member main body 21, which will be described later. ing. The thickness of the side protection member main body 21 is determined when the movable shelter 1 is swayed sideways due to wind or the like while the movable shelter 1 is being lowered to the ground, and the degree of swaying is below the allowable limit. When touching the ground, mobile shelter 1
When an impact load is applied to the lower corner or the cushioning material 11 from the lateral direction, diagonal direction, etc., this impact load is transferred to the cell walls 2 of the vapor honeycomb material 22 forming the side protection member main body 21.
It is formed to a thickness that can be sufficiently absorbed by the buckling of 2b.

A surface protection sheet 14 is attached to each open end surface of the cells 22a of the vapor honeycomb material 22 forming the side protection member main body 21, and the surrounding area is vacuum-bag packed with a waterproof sheet material 15. covered by.

The side protection member 20 has this structure.

Next, the means for attaching the buffer t411 to which the side protection member 20 is attached will be explained.

When attaching the GM material 11 to which the four-part protection member 20 is attached to the movable shelter 1, the M product 11 and the lower end of each side protection member 20 are aligned in advance, and the outer surface of the cushioning material 11 is After each side protection member 20 is placed in a predetermined positional relationship and in contact with each other, the side protection member 20 is fixed to the M surface material 11 using an adhesive tape, a mounting belt, or the like. Thereafter, the upper surface of the buffer material 11 to which the side protection member 20 is attached is brought into contact with the lower surface of the corner of the movable shelter 1, and the inner surface of the protrusion of the side protection member 20 is brought into contact with lTI! It can be easily attached by placing it in contact with the outer surface of the lower end of the I wall 3 and the end side wall 6 and then attaching it with an attachment belt or the like. (See FIGS. 2 and 3) Therefore, according to this embodiment, the movable shelter 1 to which the side protection member 20 is attached and the cushioning material 11 is not attached is supported by the M material 11 on the lower surface of each corner. In addition, the side walls 3 at each corner, the outer surface of the lower end of the end side wall 6, and the outer surface of the cushioning material 11 are covered with a side protection member 20.

Therefore, when lowering the movable shelter 1, the movable shelter 1 is swayed sideways due to wind or the like during the lowering, and the degree of the sway is within the permissible limit.
When touching the ground, the lower corner of the mobile shelter 1 or the cushioning material 11
Even when a large impact load is applied from the lateral direction, diagonal direction, etc., this WI impact load is absorbed by the buckling of the cell walls 22b of the vapor honeycomb material 22 forming the side protection member main body 21. Therefore, when such a situation occurs, the function of the f:J ribbon fTf material 11 is not impaired, and the loaded equipment can be more safely protected.

In addition, since the side protection member 20 and the cushioning material 11 are formed separately, it is possible to use the side protection member 2o only when it is assumed that it is necessary, and it is also possible to use the side protection member 2o during transportation, storage, etc. is also easy.

Next, other examples of attachment means for the M-face material 11 will be explained.

FIG. 5 is a partially cutaway front view showing other attachment means such as a cushioning material.

In the figure, 40 is a mounting member, and this mounting member 40
consists of a fixed cushion 41 and a support member 42.

The fixed cushion 41 has a compressive strength higher than the compressive strength of the vapor honeycomb material 13 constituting the cushioning material main body 12,
For example, the honeycomb panel 43, which is made of an aluminum honeycomb material as a core material and has aluminum surface plates attached to both sides, has an appropriate thickness, so that the space between the upper surface of the cushioning material 11 and the road, shape, and size. It is formed. Further, an insert nut 46 is embedded in a suitable portion of the fixed cushion 41 so as to open on the surface plate.

The support member 42 is formed of a light metal plate, such as an aluminum plate, which is considerably thicker than the surface plate of the honeycomb panel 43 constituting the fixed cushion 41. Floor part 4 formed to size
2a, and wall portions 42b vertically erected along the two outer edges of the floor portion 42a.

Upper mounting brackets 31 for hanging the mounting belt 30 and mounting bolt fixing brackets 45 for fixing mounting bolts 44, which will be described later, are arranged side by side at both ends of the outer upper part of the wall portion 42b. has been done.

In addition, lower mounting brackets 32 are provided with tip portions protruding from the portions corresponding to the upper mounting brackets 31 on the edge of the floor portion 42a facing the wall portion 42b.
is installed. Further, a support member 4 is provided on the floor portion 42a.

Therefore, according to the attachment means in this embodiment, in particular, the structure of the mobile shelter 1 has, for example,
Even in the case of a treetop structure with a skid 60 etc. protruding, the movable shelter 1
Since the cushioning material 11 can be attached to the lower corner of the frame via the attachment member 40, which cannot be attached firmly and stably,
The y1 shock member 11 can be attached extremely firmly and stably.

In addition, since the M'fR material 11 is installed in a state where it is fully supported by the fixed cushion 41 and the floor part 42a of the support member 42, during installation,
When an impact load is applied to the cushioning material 11, for example, by the skid 60, only a part of the cushioning material 11 is first deformed or damaged, and its effective stroke is not impaired. can be formed to the minimum required size. Therefore, storage, handling, etc. of the II-threaded timber 1 are easy.

Furthermore, when touching the ground, for example, if an obstacle with a sharp tip, etc.
In the event that an obstacle or the like collides with the li material 11 and breaks through a part of the cushioning material 11 or even a part of the fixed cushion 20, the movable shelter 1 is a fixed cushion 20 or a support member 42
The movable shelter 1 will not be damaged because the shock is also cushioned by the cushion material 48 attached to the support member 42.

Note that the configuration of the mounting member 40 is not limited to this embodiment, and for example, the mounting member used for the M material attachment 11 to which the above-mentioned side protection member 20 is attached may further include support. The height of the inner portion 42b of the member 42 may be formed higher, and a fixed cushion for protecting the lower end portions of the side wall 3 and the end side wall 6 may be provided on the outer surface of this wall portion 42b.

Further, the mounting member may be composed of only a fixed cushion. Further, regarding the attachment means, etc., the attachment member and the cushioning material may be attached at the same time using an attachment belt or the like.

As described above, the l! Regarding the i-device, an example was explained in which it was used in the mobile shelter 1.

"Effects of the Invention" As described in detail above, according to the shock absorbing device for a moving box-like structure according to the present invention, when transporting a moving box-like R4 body by hanging transport using a helicopter, for example, The condition of the ground is uneven or sloping, and the condition is at the limit where it is permissible for the moving box-shaped #I structure to be lowered, and when it touches the ground, there is a large impact load on the shock absorber. Even if the impact load is applied, it can absorb the impact load and prevent the loaded equipment from being damaged, and also eliminates the need for troublesome work such as constant inspection and maintenance. It goes without saying that it is easy to handle and inexpensive, but also that the quality of the cushioning material deteriorates during long-term storage or transportation. It is extremely easy to handle during storage, transportation, etc. Furthermore, even when used in rainy weather, there is no need for complicated covering work, and even if there are puddles or wet areas, it is extremely easy to handle. Even when it is dropped at a destination like this, its performance does not deteriorate, such as the effective stroke being lost, and it can fully perform its function.

In this way, the problems that existed in this type of conventional example are completely eliminated, and the effects of the present invention are remarkable and great.
