Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for transporting cargo between various transportation lines such as trucks, freight cars, ships, and airplanes, or between containers, etc., in which cargo is loaded and transported. Loading place (hereinafter referred to as loading platform)
It is related to load fixing means to prevent cargo from collapsing by fixing the cargo to the ground. This is mainly applied to items handled in individual units, such as small items), furniture, works of art, and musical instruments.

■ In the above-mentioned means of transporting cargo, the conventional and common method of securing the cargo is to fasten the cargo to the loading platform using robes or rubber bands. Taking a truck as an example, the cargo is They are loaded one after another from the center of the truck bed, and are held in place by wrapping a lobe or rubber band around the rear end of the load.

There is also a cushioning method in which a blanket, foam material, or other elastic body is inserted into the gap between the wall plate of the loading platform and the load, or between the loads to stop the movement of the load. This method is widely used in conjunction with the rubber band tightening method.

However, due to the relationship between the loading platform size and the cargo size, in most cases a gap is created between the loading platform side wall and the cargo, causing the cargo to collapse during transportation. tends to occur.

In addition, cardboard boxes with robes or rubber bands are pressed strongly locally, which may cause deformation of the box and damage the contents.

Furthermore, in this method, there is no force to hold the entire load, so the load gradually collapses from the top.

To avoid this, many lobes are required, which increases the number of man-hours required for cargo handling.

On the other hand, in the cushioning material sandwiching method, there is generally no force to stop the movement of the load, so even if the load does not collapse, the contents may be damaged by the movement of the load, and many cushioning materials may be sandwiched individually. Since it has to be carried out in a crowded manner, the number of man-hours required for cargo handling increases.

As described above, all of the conventional transportation fixing methods have insufficient effects to prevent the cargo from collapsing or suppress the movement of the cargo, resulting in constant transportation troubles. For this reason, the current situation is that not only does it require a lot of man-hours for cargo handling, but it also causes a lot of mental fatigue during driving.

! Therefore, the present invention stabilizes various cargoes transported by means of cargo transport such as trucks and containers by compressing them with a movable wall body provided in the loading platform. The purpose of the movable wall body 1 according to the present invention is to hold the cargo, prevent the movement of the cargo, prevent the cargo from collapsing, and facilitate the cargo handling work.
A fixing plate 2 that can be attached to or is made of a loading platform wall plate of a cargo transport means, an elastic body 3 that is attached to the fixing plate and can be expanded and contracted in a direction perpendicular to the fixing plate, and a It consists of a movable wall plate 4 which is attached to be sandwiched between the fixed plate and moves according to the expansion and contraction of the expandable body.

This movable wall body 1 is attached to a loading platform, that is, a wall plate of a cargo loading area, by fixing or suspending a fixed plate 2. Then, the telescopic body 3 is contracted and the cargo is loaded in a state where the cargo loading space on the loading platform is wide, and then the telescopic body 3 is extended to move the movable wall plate 4 inward toward the cargo, and the movable wall plate 4 The cargo is clamped into a pressure tube and fixed. Depending on the case, the loading platform wall plate may also be used as the fixing plate 2.

above the child The present invention will be explained below by way of examples not shown in the accompanying drawings.

FIG. 1 somewhat conceptually shows a movable wall body 1 according to the present invention installed on a loading platform 5 of a truck.
surrounded on the sides and top by Note that the rear wall plate forming the door section at the rear end is shown removed.

In this embodiment, both side wall plates 6a 1. CB dynamic wall face piece 1 is fixed.

The movable wall body 1 is made up of three layers: a fixed plate 2, an expandable body 3, and a movable wall plate 4. The fixing plate 2 is a rigid plate fixed to the loading platform side wall plate 6a by bolts 7 and in contact with the side wall plate 6a, and is provided with a gas supply/exhaust port, as will be described in detail later. The extensible body 3 consists of an airtight hollow bag-like body whose one end surface is hermetically fixed to the fixed plate 2, and is made of a material such as rubber or resin that has good airtightness and is resistant to bending fatigue due to expansion and contraction, and is able to expand and contract freely. It is made. The hollow part of this expandable body 3 communicates with the gas supply/discharge port provided in the fixed plate 2, and L12
By supplying and discharging gas such as air into the hollow portion through the supply and discharge port, the expandable body 3 expands and contracts in a direction perpendicular to the fixed plate 2, as shown by arrow a in FIG. The movable wall plate 4 is attached to the extensible body 3 so as to cover the outer end surface of the extensible body 3, and moves according to the expansion and contraction of the extensible body 3 until the extensible body 3 is in the extended position shown by the solid line in FIG. When carrying the cargo, it comes into contact with the side of the cargo 8 and is pressed against it, fixing the cargo 8 and preventing its movement. For this reason, the movable wall plate 4 is made of an elastic material such as rubber or soft resin so that it conforms well to the shape of the load.

When loading the cargo 8 onto the carrier 5, the gas inside the expandable body 3 is removed to bring it into a contracted state as shown by the dotted line, and the load 8 is loaded into the relatively wide space, and then the expandable body 3 is The moving wall plate 4 is expanded by supplying gas inside the movable wall plate 4.
By crimping the cargo 8 to the side surface of the cargo 8, the cargo 8 is fixed to the loading platform 5 and prevented from shifting or collapsing during transportation. The cargo 8 is not limited to one piece of cargo, but can also be, for example, a large number of cardboard boxes lined up in a mfQ manner, and such a large number of cargoes can be crimped and fixed together by the movable wall plate 4.

Figures 2 and 3 show in more detail an example of the movable wall body that is attached to the side wall plate of the truck bed as described above. The movable wall body 1 is provided with an air cushion 3 in the form of a bag-like elastic body rope similar to that shown in FIG. The air cushion 3 is made of a sheet material made of rubber or resin, has a large pleat 9 in the middle, and is expandable and contractible in the direction of arrow a perpendicular to the surface of the fixed plate 2.

The fixed plate 2 is provided with a gas supply/discharge port 10 opening into the center of the air cushion 3, and this gas supply/discharge port 10 is connected to a truck-mounted air compressor (not shown) through a gas supply/discharge pipe 11. ing.

For example, the gas supply and exhaust pipe 11 is attached to the fixing plate 2 so that it does not get caught between the fixing plate 2 and the loading platform wall plate 6a (FIG. 1).
The piping is routed through a concave part on the back of the pipe.

A pressure receiving plate 4 made of a movable wall plate, that is, a rubber plate, is integrally connected to the inner end surface of the air cushion 3, that is, the end surface on the cargo side. When extended, it is crimped onto the load. −
As an example, the thickness 2 during air cushioning is approximately 20
Cm, and the air cushion has approximately 0.01 Kpi/
AI's secret information is stolen.

In this embodiment, as can be seen from FIG. 3, a plurality of air cushions 3 are provided on one long fixing plate 2, and this fixing plate 2 is attached to a bolt 13 via a hanger 12 to the side wall of the loading platform. It is designed to be suspended from a plate 61). Of course, a plurality of movable wall bodies each having a fixed plate may be hung on the loading platform wall plate 6b, and instead of being hung, the first movable wall body may be
It may be fixed at ports 1 to 1 as described in the figure.

The movable wall surface body 1 shown in FIGS. 4 and 5 employs an accordion-shaped air cushion 14 that has many folds on a cylindrical surface as an extensible body and is freely extensible and retractable in the linear direction. One elastic body is made up of 11-
J is formed, and one movable wall plate 4 is stretched across these four air cushions 14. The movable wall plate 4 consists of a rigid aluminum pressure receiving plate 15 that receives reaction force from the cargo and transmits it to each air cushion 14, and a foam cushioning material 16 that covers the surface of this pressure receiving plate 15. 16 shows the elastic contact that conforms to the shape of the cargo.

The fixed plate 2 is provided with a gas supply/discharge port 10 at the center position of each air cushion 14, and each supply/discharge branch pipe 11 connected to these gas supply/discharge ports 10, 10...
a, 11a, . . . are combined into one gas supply/discharge pipe 10 and connected to a truck-mounted air compressor.

In this embodiment as well, a plurality of movable wall surfaces are arranged on a common fixed plate 2 of one cell 1.

FIG. 6 shows a movable wall body similar to that shown in FIG. 2.3, in which the air cushions 3 are communicated with each other through the communication holes 18, and the gas supply/discharge ports and supply/discharge pipes (not shown in FIG. 6) are connected to each other. An embodiment in which the number of air cushions 3 is reduced and the internal pressure of each air cushion 3 is made equal will be shown.

In each of the embodiments described above, the fixed plate 2 is fixed or suspended from the loading platform wall plate 6, so that the movable wall body of the present invention can be easily installed on an existing loading platform. However, if the movable wall body of the present invention is installed on the loading platform from the beginning,
It is possible to use both the loading platform wall plate and the fixing plate. That is, the expandable body may be directly attached to the loading platform wall plate, and the present invention also includes such a movable wall body.

The movable wall body of the present invention may be installed on any wall plate of a loading platform having wall plates, and its installation position is appropriately selected depending on the configuration of the vehicle. ′? Figures S7 (al to (d)) show typical examples of installation positions of the movable wall body 1 that is pulled onto the truck bed.S7 (a) shows the side wall plate 6a/ of the truck bed 5 as well as in Figure 1.
(b) is also installed on the ceiling wall board 6b.

(C) is a full-scale installation type in which the front wall board 6CJ5 and the rear wall board 6d are installed in addition to the side wall board 5a and the ceiling wall board 61), and the rear wall board 6d is usually a door.

FIG. 7(d) shows an example in which the movable wall body 1 according to the present invention is attached to the side wall plate 6a of a loading platform equipped with an automatic cargo handling device. The loading platform is provided with a conveyor 20 with a gate screen 19 erected thereon, and the cargo loaded from the rear of the loading platform is carried to the center by the conveyor 20, and is crimped and fixed on both sides by the extension of the movable wall 1. This greatly reduces and shortens loading and unloading work.

The embodiments in which the present invention is applied to truck beds have been described above, but the present invention is not limited to trucks, but can also be applied to various types of transportation such as ships, airplanes, and freight cars, and can also be applied to containers in container transportation. can. Furthermore, it goes without saying that the present invention is not limited to the illustrated embodiments, and as described in the text, numerous modifications can be made within the scope of the present invention.

The moving wall body for fixing cargo of the present invention exhibits an excellent effect in preventing cargo from collapsing in means of transporting cargo. In other words, since the movable wall body is in contact with or press-fitted to the load surface, the load is suppressed from shifting laterally or longitudinally due to inertia force, centrifugal force, vibration, etc. during transportation, and the load is prevented from collapsing. Even when this movable wall body is installed on the side walls of the loading platform on the left and right in the direction of travel, it holds the entire side of the load, preventing it from shifting due to the back and forth forces associated with starting and stopping, and preventing the load from collapsing. can do.

Moreover, according to the movable wall body of the present invention, damage to the stack can be prevented. However, since the movable wall body presses the load in close contact with the entire load, there is very little planar movement and vertical movement of the load, and there is no damage to the contents of the cardboard box or the like. Even if a sudden force is applied, there is no damage to the packaging or contents due to the cushioning effect of the elastic body.

Furthermore, by installing the movable wall body of the present invention, the work of hanging robes and closing gaps becomes unnecessary, and cargo handling work such as loading and unloading becomes simple and quick.

Furthermore, the effect of preventing cargo from collapsing during transportation reduces the influence of driving methods on the cargo, thereby significantly reducing the mental burden on the driver.
