DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transport container, a transport carrier and a container device which are preferably used when various kinds of cargo are mixedly loaded on a transport vehicle or the like.

[0002]

2. Description of the Related Art In recent years, a carrier has widely obtained information on the empty space of a truck carrier from a truck using a wide area information transmission network such as the Internet, and has also gathered information on customers of cargo transport to collect information. There have been attempts at various places to develop a transfer plan so as to satisfy the demand of the above, and to transfer the transfer plan to both sides (that is, the supply side and the demand side) to thereby improve the efficiency of the transfer operation. By realizing such a transport system, it is possible to target not only trucks within the same company but also trucks across many companies, and it is possible for cargo owners to efficiently stack different packages. Therefore, it is expected that the inconvenience of, for example, running a return flight with empty or small luggage will be resolved, thereby contributing to the improvement of transport efficiency on a nationwide scale.

[0003] It can be said that the use of such a wide-area information transmission network to cope with the transportation system in terms of software has already been established, but the fact is that there are few lorries that are compatible with this transportation system. It is true that the transport system is not functioning effectively as a result.

A lorry is roughly classified into a box-type canopy having a canopy, such as a van and a wing car, and an open car having a flat canopy without a canopy, such as a truck or a semi-trailer. However, the proportion of canopies that protect their cargo from the rain is not so high, with more open cars. However, when there are cargoes that do not want to get wet in the rain, it is not suitable to use open vehicles, which makes it difficult to incorporate open vehicles into the transport system despite the fact that there are more vehicles than open vehicles. There was an inconvenience.

[0005]

Therefore, even in the case of an uncovered vehicle, even if the luggage that does not like to get wet is mixed, the luggage is covered with a waterproof sheet, or a waterproof tent is mounted on the luggage carrier. In some cases, the container may be mounted on a carrier and transported while the package is stored in a container that is a waterproof container.

However, when the luggage is covered with the waterproof sheet, the operation is very troublesome. Even if the luggage is covered with the waterproof sheet, rainwater enters from the gap between the sheets, so that a reliable waterproof effect can be obtained. There is a problem that it is not possible.

[0007] Even if a tent is attached to the carrier of the carrier,
Since it is difficult to make the top of the bed tightly closed, there is a problem in that rainwater invades from the gap between the tents during a downhill and the like, and a complete waterproof effect cannot be expected.

[0008] In comparison with these, the container has a greater effect of preventing rainwater from entering the interior, so that even if the luggage does not like to get wet, the container is used to ensure that the luggage does not wet the destination. It can be transported to

However, if a container is to be used, it is necessary to secure the container to the carrier so that the container does not fall off the carrier due to the vibration of the carrier during transportation or the turning of the truck. A locking portion for tensioning is provided on the placing surface, and a locking projection corresponding to the locking portion is provided on the bottom plate of the container. Then, the container is prevented from falling off by locking the locking portion of the loading platform to the locking projection.

Therefore, the container carrier has a large number of locking projections at various locations, and these locking projections hinder the loading of the cargo other than the container on the loading platform. As a result, there is a problem that the lorry must be dedicated to the container, and the lorry cannot be used for versatile mixed loading.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it has been made possible to mix a load that does not like to get wet with normal loads, thereby allowing an open-type vehicle to be used in an extensive transport system. It is an object of the present invention to provide a transport container, a transport carrier, and a container device that can be mounted on a route to improve overall transport efficiency in Japan.

[0012]

According to the first aspect of the present invention,
A transport container mounted on the transport carrier, which has a width slightly smaller than the width of the carrier, and has a rectangular parallelepiped container body having an opening / closing door on at least one side, and a lower portion provided at the bottom of the container body. projecting towards, and at least three support legs supporting the container body, Ri Do and a shroud which surrounds the top plate of the container body from all sides, the container body is a rectangular parallelepiped set
The frame that was found and was stretched around the periphery of this frame
A side plate, a bottom plate provided at the bottom of the frame, and the frame
It can be sealed by the top plate provided on the top of the
At the lower end of the support leg, a recess is formed in the carrier.
A flange portion fitted into the fitted fitting concave portion .

According to the present invention, at least three support legs are provided at the bottom of the container main body, and the container main body is placed on the open-top carrier to thereby enable the container main body to use the three support legs. Stand on the carrier in a stable state. Then, in a state where the container body is placed on the carrier, each support leg is fastened to a part (hook or the like) of the enclosure member of the carrier using a rope or the like, so that the container body is used for the traveling vehicle. It is transported without falling even by vibration or turning. By providing the support legs on the bottom of the container body in this manner, it is not necessary to provide a projection for tightening the container body on the surface of the carrier. Can be used for loading ordinary luggage, and the consolidation of container transportation and ordinary luggage without using a container can be realized without any trouble.

Therefore, by using such a container, the luggage which does not like to get wet is surrounded by the side plate, the bottom plate and the top plate.
In such a case, luggage that does not interfere with rain can be placed directly on the carrier while small items that may be wet can be placed in the enclosure on the top plate of the container body. It is now possible to mix and sort different types of luggage more efficiently than ever before, and this has enabled the use of wide-area mutual information networks, such as the Internet, to balance supply and demand of uncovered vehicles that were previously considered unsuitable. It will be possible to incorporate it into a transport system that dispatches vehicles according to the schedule, thereby improving global transport efficiency taking into account the entire country.

Also , a flange is provided at the lower end of the support leg .
Therefore , the container body can stand up in a more stable state due to the presence of the flange provided on the support leg.

[0016] According to a second aspect of the invention, a transport bed for mounting a transport container of claim 1 wherein the floor plate for placing a transport container, the support legs at positions corresponding to the support leg Is provided with a fitting concave portion.

According to the present invention, the container body is loaded on the carrier and the support legs are fitted into the fitting recesses formed in the carrier, so that when the container body is inclined to fall down, the flange is formed. Since it interferes with the inner wall of the fitting concave portion, the container body is securely prevented from tipping over. Further, in a state where the support leg is fastened with a rope or the like, the rope is prevented from falling out of the support leg due to the presence of the flange portion, so that the container body is more securely tightened to the carrier.

According to a third aspect of the present invention, in the second aspect of the present invention, there is provided a tightening means for tightening and loosening the flange so that the support leg fitted in the fitting recess does not come off. It is characterized by being carried out.

According to the present invention, since the flange is tightened by the tightening means and is prevented from being pulled out in a state where the support leg is fitted in the fitting recess, the support leg does not need to be fastened with a rope or the like. Thus, the container body is prevented from rolling over.

According to a fourth aspect of the present invention, in the third aspect of the present invention, the tensioning means has a bottom-facing projection which is fitted at one end, penetrates the bottom plate of the concave portion, and faces the support leg bottom. On the other hand, at the other end, a partly notched tensioning wheel provided with a flange-facing projection penetrating the peripheral wall of the fitting recess and facing the upper surface of the flange, and turning the tensioning wheel around its center. It is characterized by comprising a central shaft movably supported and a return means for applying a force so that the bottom-facing projection is directed toward the bottom of the support leg.

According to the present invention, the tensioning wheel usually has a state in which the bottom-facing projection projects upward from the bottom plate of the fitting recess by the return means. When the support leg of the container body is immersed in the fitting recess in this state, the bottom of the flange presses the bottom opposing projection downward against the return means due to the weight of the container body, so that the tensioning wheel is at the center. The flange is turned around the axis in the immersion direction, whereby the flange-facing projection facing the flange from the peripheral wall of the fitting recess is extended into the fitting recess, and its tip faces the surface side of the flange, and the flange is Are sandwiched between the two projections, and the state of insertion of the support leg into the insertion recess is stabilized.

When the support leg suddenly jumps out of the recess due to the vibration of the vehicle or the like, the front side of the flange is brought into pressure contact with the tip of the flange-facing projection. The rotation of the tensioning wheel around the central axis by the means is restricted, and the support leg is prevented from being pulled out of the fitting recess. Therefore, the container body is reliably prevented from rolling over due to the support legs coming out of the fitting recesses.

When lowering the container body from the carrier, the container body may be gently lifted using a working machine such as a forklift or a crane. Then, the supporting leg gradually rises, so that the bottom-facing protrusion that is in contact with the bottom of the flange portion rises while maintaining the abutting state by the action of the return means, and as a result, around the central axis of the tensioning wheel. Because the flange-facing projection is pulled back into the peripheral wall of the fitting recess by the rotation, the support leg can be pulled out of the fitting recess without the flange being interfered by the flange-facing projection. The main body is unloaded from the carrier.

By providing such a tensioning means,
When the container body is loaded, there is no need to perform any special tightening operation, just perform the operation of fitting the support legs into the fitting recesses, so that the support legs are reliably prevented from coming out even by vibration etc. At the time of unloading, the tension is automatically released, so that the container body can be prevented from rolling over and the cargo handling operation can be simplified.

According to a fifth aspect of the present invention, in the fourth aspect of the invention, the return means is a spring means for applying a restoring force so that the bottom-facing projection is directed toward the bottom of the support leg. Is what you do.

According to the present invention, the bottom-facing projection of the tensioning wheel is brought into a state in which the tip is pressed against the bottom of the support leg by the biasing force of the spring means.

According to a sixth aspect of the present invention, in the fourth aspect of the invention, the return means is a weight attached to a proper position of the tensioning wheel so that the bottom-facing projection is directed toward the bottom of the support leg. It is characterized by the following.

According to the present invention, the bottom-facing projection is directed in the direction in which the tensioning wheel comes into contact with the bottom of the support leg by the rotation about the center axis due to the weight of the weight. It is in a state where it is pressed against the bottom.

The invention according to claim 7, a container device used for mounting in a clamping state transport bed a transportable <br/> container for feed according to claim 1, loading platform for the upper Symbol conveyor Is
A container comprising: a fitting concave portion for fitting the support leg into a floor plate on which the transport container is placed; and a tightening means for tightening the support leg fitted in each concave portion. Device.

According to the present invention, the transport container is loaded on the carrier, each support leg is fitted into the fitting recess formed in the carrier, and the support leg fitted into the fitting recess is tightened. Since each support leg is kept in a stopped state by being tightened by the means, it is possible to reliably prevent the container from tipping over due to vibration of the carrier. Also, since the loading platform is formed with a recess instead of the conventional locking projection, there is nothing on the surface of the loading platform that hinders the loading of luggage.Therefore, mixed loading of containers and ordinary luggage is not possible. This makes it possible to improve the versatility of the carrier for the load.

When the support leg 3 rises rapidly due to vibration of the support leg 3, the tensioning wheel 52 cannot follow the sudden rise, and the flange portion 32 collides with the second operating end 52e. 3 is prevented from falling out of the cup body 51.

FIGS. 5 and 6 are explanatory views in a sectional view for explaining the operation of the tensioning means 5. FIG.
5B is a state immediately before the support leg 3 is fitted into the cup body 51, FIG. 5B is a state in which the support leg 3 is being fitted into the cup body 51, and FIG. 5
6 (b) in a state where it is slowly coming out of 1
Indicates a state in which the support leg 3 has risen rapidly.

First, when loading the container 1 onto the loading platform 91, the container body 2 is lifted by a forklift (not shown) so that the four support legs 3 correspond to the four fitting recesses 90 of the loading platform 91. After positioning the main body 2, the container 1 is gently lowered,
As shown in FIG. 5A, the support leg 3 is fitted into the cup body 51, and the upper end of the first operation end 52d comes into contact with the receiving recess 32a of the flange 32.

When the container 1 is further lowered in this state, the flange 32 presses the distal end of the first operating end 52d downward.
5 (FIG. 4), rotates clockwise around the tension shaft 53 against the urging force of FIG. 4, and the first operation end 52 d enters the bottom insertion hole 51 b, and the second operation end 52 e is Part insertion hole 5
As shown in FIG. 5B, the distal end of the second operating end 52e abuts on the peripheral surface of the support leg body 31 slightly above the flange 32, as shown in FIG. Support leg 3
Is sandwiched between the first and second operation ends 52d and 52e.

Next, when unloading the container 1 once loaded on the loading platform 91, once the container 1 is gently lifted using a forklift (not shown), the support legs 3 gently move inside the cup body 51. To rise to the flange 32
The first operating end 52d in contact with the receiving recess 32a follows the flange 32 by the urging force of the coil spring 55, whereby the tensioning wheel 52 rotates counterclockwise around the tensioning shaft 53. As a result, as shown in FIG. 6A, the second operating end 52e is released from the cup body 51, and the engagement of the second operating end 52e with the flange 32 is released, and the support leg 3 is released. Comes out of the cup body 51.

Then, while the lorry 9 is running, the loading platform 91
When the container 1 suddenly rises due to vibration of the container 1, the support leg 3 rises rapidly in a direction to come out of the inside of the cup body 51, but the tensioning wheel 52 rotates slowly due to the presence of the absorber 56. It is not possible to follow the rise of the leg 3, so that the flange 32 of the support leg 3 interferes with the second operating end 52e as shown in FIG. The escape from the body 51 is prevented. Therefore, even if the carrier 91 vibrates while the lorry 9 is traveling, the support leg 3 is moved to the cup body 51.
As a result, the container 1 can be reliably prevented from dropping off the carrier 91.

FIG. 7 is a side sectional view showing another embodiment of the tightening means. In this tensioning means 5a, the coil spring 55 and the absorber 56 are not employed. Instead, a weight 57 made of a heavy metal such as lead is provided at an appropriate position of the tensioning wheel main body 52a (specifically, at a point symmetrical position with respect to the tip end of the first operating end 52d and the tensioning shaft 53). The weight of the weight 57 imparts a force to the tensioning wheel 52 to rotate counterclockwise around the tensioning axis 53. Other configurations of the tensioning means 5a are the same as those of the tensioning means 5 of the previous embodiment.

According to the tensioning means 5a of the second embodiment, the tensioning wheel 52 is

Effects of the Invention According to the first aspect of the invention, the bottom of the container body, for at least three support legs are provided, three or more by placing the container body in the bed of no lid The support legs can stably stand on the carrier. Then, in a state where the container body is placed on the carrier, each support leg is fastened to a part (hook or the like) of the enclosure member of the carrier using a rope or the like, so that the container body is used for the traveling vehicle. It is transported without falling even by vibration or turning. In this way, by providing the support legs on the bottom of the container body, it is not necessary to provide a projection for tightening the container body on the surface of the loading platform. It is possible to load ordinary luggage on the loading platform, and it is possible to carry out container transportation and mixed loading of ordinary luggage without using containers.

Further, since the surrounding member is provided so as to surround the top plate of the container main body, it is possible to place luggage which does not hinder the rain on the top plate, thereby improving the overall loading efficiency. be able to.

Therefore, by using such a container, luggage which does not want to be wet can be stored in the container body, while luggage which does not cause any trouble even when wet can be directly placed on the loading platform.
In addition, it is possible to mount small items that may get wet in the enclosure inside the enclosure on the top plate of the container body. It can be used in a transport system that distributes vehicles according to the supply and demand balance, and can improve global transport efficiency taking into account the entire land area.

[0088] In addition, since having a flange portion at the lower end portion of the support leg can be erecting in a more stable state container body by the presence of the flange portion.

According to the second aspect of the present invention, the carrier is provided with a fitting recess for fitting the support leg at a position corresponding to the support leg of the floor plate on which the transport container is placed.

Further, in a state where the support leg is fastened with a rope or the like, the rope is prevented from coming off from the support leg due to the presence of the flange portion, so that the container body can be more securely tightened to the carrier.

According to the third aspect of the present invention, since the tightening means is provided for tightening and loosening the flange so that the support leg fitted into the fitting recess is not removed, the support leg is provided with the fitting recess. In the state of being fitted into the container, the flange portion is tightened by the tightening means and is prevented from being pulled out, whereby the container body can be reliably prevented from overturning without fastening the support legs with a rope or the like.

According to the fourth aspect of the present invention, the tensioning means includes a partially notched tensioning wheel having a bottom-facing projection and a flange-facing projection, and turning the tensioning wheel around its center. Since the center wheel is movably supported and the return means applies a force so that the bottom-facing projection is directed toward the bottom of the support leg, the tensioning wheel is usually fitted with the bottom-facing projection by the return means. When the supporting leg of the container body is immersed in the fitting concave portion in this state, the bottom of the flange portion resists the bottom facing projection against the return means due to the weight of the container body. Then, the tensioning wheel is rotated about the central axis in the above-mentioned immersion direction, and the flange-facing protrusion facing the flange from the peripheral wall of the fitting recess is extended into the fitting recess and the tip thereof. Faces the front side of the flange so that the flange is It has been fitted state of the state since it into the recess the fitting of the support leg can be stabilized.

When the support leg jumps out of the recess due to the vibration of the vehicle or the like, the front surface side of the flange is pressed against the tip of the flange-facing protrusion, and the large pressure resistance at this time causes a return. The rotation of the tensioning wheel around the central axis by the means is restricted, and the support leg can be reliably prevented from coming out of the fitting recess. Therefore, it is possible to reliably prevent the container body from rolling over due to the support legs coming out of the fitting recesses.

When unloading the container body from the loading platform, the container body is gently lifted using a working machine such as a forklift or a crane, so that the bottom-facing projection abutting against the bottom of the flange portion is brought into contact with the return means. The flange is opposed to the flange because the flange opposing protrusion is pulled back into the peripheral wall of the fitting recess by the rotation about the central axis of the tensioning wheel, thereby gently ascending while maintaining the contact state. The container body can be pulled out of the fitting recess without being interfered by the part opposing projection, and the container body can be unloaded from the carrier.

By providing such a tightening means,
When the container body is loaded, there is no need to perform any special tightening operation, just perform the operation of fitting the support legs into the fitting recesses, so that the support legs are reliably prevented from coming out even by vibration etc. At the time of unloading, the tension is automatically released, so that the container body can be prevented from rolling over, and the cargo handling operation can be simplified.

According to the fifth aspect of the present invention, since the spring means for applying an urging force so that the bottom-facing projection is directed toward the bottom of the support leg is used as the return means, the tip of the bottom-facing projection of the tensioning wheel is used. The state of being pressed against the bottom of the support leg can be brought about by the urging force of the spring means.

According to the sixth aspect of the present invention, since the weight attached to the proper position of the tensioning wheel so that the bottom facing projection is directed to the bottom of the support leg is used as the return means, the bottom facing projection is formed by the tensioning wheel. Can be directed in the direction of contact with the bottom of the support leg by rotation about the center axis due to the weight of the weight, so that the tip of the bottom-facing projection is pressed and stopped against the bottom of the support leg. Can be.

According to the seventh aspect of the present invention, the container device is provided with at least three support legs for supporting the container body, and the transport bed is mounted on the floor plate on which the transport container is placed. And a tightening means for tightening the support legs fitted in the respective recesses, so that the transport container is loaded on the carrier and each support leg is recessed in the carrier. Each supporting leg is fitted into the fitting concave portion, and the supporting legs fitted into the fitting concave portion are tightened by the tightening means. Can be prevented.

[0098] Further, since the concave portion is formed in the loading platform in place of the conventional locking convex portion, there is no obstacle on the surface of the loading platform that hinders the loading of the load, and therefore, the container and the normal load are mixed. Is possible, and the versatility of the carrier for the load can be improved.
