Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a cargo compartment structure of a cargo compartment installed on the loading platform of a freight vehicle, and in particular, to a cargo compartment with thick sides (openable). Regarding the side-open luggage compartment structure.

[Prior Art] Conventionally, in the technical field of freight vehicles, in order to facilitate the loading and unloading of cargo into the cargo compartment, structures that open the sides of the cargo compartment over the entire surface, such as wing doors, have been developed. Various structures, vertically split doors, accordion curtain doors, etc., have been proposed and implemented.

In other words, in a freight vehicle with such a side-openable luggage compartment, it becomes possible to load and unload cargo using the mechanical power of a forklift from the side of the vehicle, which was not possible with conventional pan-type vehicles. In addition, for oven decks that can be handled by forklifts, the work of attaching and detaching the sheets to protect the cargo, which was essential, has been achieved. As each has its own merits,
It is currently in widespread use.

[Problems to be Solved by the Invention] However, although it is certainly convenient for loading and unloading cargo all at once in a freight vehicle having such a cargo compartment that can be opened on the side, it is difficult to load and unload cargo little by little. , When unloading the cargo little by little, the sides of the luggage compartment must be widened (opened), which is very inconvenient, even for such a small amount of luggage.

For example, this is especially noticeable in the case of a luggage compartment with a wing door, and when the wing door flips upward, the sides of the luggage compartment are completely opened.
Loading of luggage into the cargo compartment can be carried out all at once using mechanical force such as a forklift. However, even when it becomes necessary to take out the loaded baggage in small quantities, it becomes necessary to flip up the wing door. Here, as the wing door rotates upward, the lower edge of the wing door becomes -
At that moment, the truck was swung wide into the side of the truck. For this reason, when loading and unloading cargo, it is necessary to secure a space on the side of the luggage compartment that is commensurate with the amount of movement, which poses the problem of, for example, making it difficult to unload cargo in a narrow alley. It has been pointed out.

This invention was made in view of the above-mentioned problems, and an object of the present invention is to open the sides widely so that a large amount of luggage can be loaded at once during loading and unloading work. However, it is an object of the present invention to provide a cargo compartment structure for a freight vehicle whose side surfaces can be opened to a small extent so that it is optimal for unloading a small amount of luggage.

[Means for Solving the Problems] In order to solve the above-mentioned problems and achieve the purpose, a cargo compartment structure for a freight vehicle according to the present invention is a luggage compartment structure of a luggage compartment installed on a loading platform of a freight vehicle. a closing member that releasably closes at least one side of the luggage compartment;
This closing member is characterized by comprising an opening partially formed at a location that defines the side surface of the cargo compartment, and a door member that releasably closes this opening.

Further, in the luggage compartment structure of a freight vehicle according to the present invention, the closing member is constituted by a wing door that is movably supported around a rotation axis disposed along the front-rear direction in the ceiling portion of the luggage compartment. It is characterized by being

Further, in the luggage compartment structure of a freight vehicle according to the present invention, the closing member is comprised of a vertically divided door supported vertically movably on a side surface of the luggage compartment.

Further, in the luggage compartment structure of a freight vehicle according to the present invention, the closing member is comprised of an accordion curtain that is attached to a side surface of the luggage compartment so as to be retractable laterally.

[Function] In the cargo compartment structure of a freight vehicle configured as described above, when loading cargo, the closing member is moved to open the sides of the cargo compartment, and a large amount of cargo is moved at a time, for example by applying mechanical force. This means that the work time for loading and unloading can be shortened, and the burden on the loading and unloading workers can be significantly reduced. On the other hand, when unloading luggage from the luggage compartment, if the amount of luggage is small, the door member is opened to partially open the side surface.

In this way, by partially opening the sides according to the baggage to be unloaded, you can, for example, make the sides thicker (even when unloading the baggage at the back of the luggage compartment without opening it, the baggage on the near side can be opened). There is no need to take it down once, and the sides can be opened without having to operate the closing member, which improves the work efficiency.

[Example 1] Below, the first embodiment of the cargo compartment structure of a freight vehicle according to the present invention will be described.
The configuration of the embodiment will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 to 3, the freight vehicle 10 of the first embodiment is mounted on a loading platform 12, with both sides independently mounted on the loading platform 12.
It has a luggage compartment 14 that can be opened over the entire surface.

That is, two partition walls 16a are provided at the front and rear edges of the loading platform 12.
, 16b are provided in an upright and fixed state. The upper central portions of these partition walls 16a, 16b are connected to each other by a beam 18 extending in the front-rear direction. On both left and right sides of this beam 18, there are luggage compartments 14.
Wing doors 20 and 22, which serve as closing members that releasably close both left and right sides of the door, are rotatably supported independently.

That is, in this first embodiment, the above-mentioned luggage compartment 14
, both partition walls 16a and 16b, and a pair of wing doors 2
It is set to be defined by the space surrounded by 0 and 22.

Here, each wing door 20, 22 has a ceiling portion 20a, 22a extending substantially horizontally to close a corresponding half of the ceiling portion of the luggage compartment 14 in a state where the luggage compartment 14 is closed.
and a side wall portion 20 integrally connected to the corresponding ceiling portions 20a, 22a so as to fall downward from the outer edge of the ceiling portions 20a, 22a.
b.

22b, it is configured in an abbreviated form.

As shown in FIG. 3, each wing door 20, 22 is biased by a corresponding spring mechanism 24, 26 from a closed position shown by a solid line to a flip-up position shown by a two-dot chain line. ing.

In addition, each wing door 20, 22 is in a closed position.
It is latched in the closed state by a latch mechanism (not shown).

On the other hand, as is clear from FIG. 2, each wing door 20,
The side wall portions 20b, 22b of 22 are partially provided with openings 28.
．． 30 is formed, and a pair of sliding doors 32a; 32b, 34a; 34b are respectively attached as door members for releasably closing the openings 28, 30. These sliding doors 32a; 32b.

34aH34b, by selectively drawing these to the side, the sides of the luggage compartment 14 are partially opened.

Further, the rear surface of the luggage compartment 14 defined by the rear partition wall 16b has a pair of rear doors 3 connected to each other in a double door structure.
It is releasably closed by 6a and 36b.

Luggage compartment 1 in freight vehicle 1o configured as above
The operation of loading and unloading cargo onto and from the vehicle No. 4 will be described below.

First, when loading cargo, for example, cargo compartment 1
Assuming that cargo is loaded all at once into the luggage compartment 14 when a freight vehicle with empty cargo truck 4 travels to the loading station and stops, the loading operator who also serves as the driver must use the latch mechanism (not shown). Release the
With the help of the biasing force of the spring mechanism 24.26, both wing doors 20.2 are opened as shown by the dashed line in FIG.
2 to the flip-up position.

By rotating both wing doors 20 and 22 in such a manner that they are each flipped up to the flip-up position, the luggage compartment 1
Both sides of 4 will be open over the entire surface.

In this way, with both sides of the cargo compartment 14 completely open, the loading operator can load a large amount of cargo at once using, for example, mechanical power such as a forklift. This means that it can be loaded into the compartment 14. The luggage loaded in this manner can be stacked in a correct order according to the order in which they are taken out, starting from the innermost part of the luggage compartment. That is, the baggage to be unloaded last is stored in the innermost part of the luggage compartment 14, in other words, the luggage to be unloaded first is stored in the front part of the luggage compartment 14. It is stored in the side part, in other words, in the rear part of the luggage compartment 14.

When the cargo loading operation is completed in this manner, both wing doors 20 and 22 are pushed down against the biasing force of the spring mechanisms 24 and 26, and rotated to the closing position where they close the sides of the luggage compartment 14. In this state, it is latched in the closed position by a latch mechanism (not shown).

In this state, the series of cargo loading operations is completed, and the driver, who is the loading operator, now drives the freight vehicle 10 to transport the cargo to the destination.

When the first destination is reached, a pair of rear doors 36a are opened.
, 36b to open the rear surface of the luggage compartment 14, from which the desired luggage can be unloaded. On the other hand, as the luggage in the luggage compartment 14 is sequentially unloaded in this manner, the open space at the rear of the luggage compartment gradually increases. As a result, the unloading worker, who was the driver, was unable to unload the cargo while standing on the ground,
4, carry the luggage to the rear loading platform, place the equipment here, jump from the luggage compartment 14, stand on the ground, and take the steps to unload the luggage. (Become..

However, such a procedure is very troublesome, so the operator must pull forward the sliding door 32b on the side where the cargo to be unloaded is located, and open the opening 30 formed on the side of the cargo compartment 14. By opening the rear part, it becomes possible to easily unload the luggage stored in the middle of the luggage compartment 14 through this open part.

When unloading luggage located at the innermost part of the luggage compartment 14, the sliding door 32 is opened on the side where the luggage to be unloaded is located.
By pulling back a and opening the front part of the opening 30 formed on the side of the luggage compartment 14, the luggage stored in the innermost part of the luggage compartment 14 can be easily unloaded through this open part. It will be possible to do this.

As described above, in this first embodiment, by partially opening the side surface of the luggage compartment 14 corresponding to the part where the luggage to be unloaded is stored, the luggage can be stored at any position in the luggage compartment 14. This makes it easier to unload loaded cargo, dramatically improving work efficiency and significantly reducing the burden on workers.

Here, the luggage compartment structure of the first embodiment configured as described above can be optimally applied not only to the above-mentioned operating conditions but also to the cases described below. be.

In other words, the order of taking out the luggage is incorrectly instructed, and based on this incorrect instruction, for example,
In the case where it is necessary to unload the baggage at an early stage while the baggage is stored, in the conventional configuration, all the baggage on the front side is first unloaded, or the wing door 20 , 22 must be flipped up. However, the former is very time-consuming, and the latter is impossible, for example, in narrow alleys where sufficient space cannot be secured on the sides.
In the end, there is a possibility that you will have to unload the baggage on the front side.

However, in this first embodiment, the luggage compartment 14
By selectively opening the sliding doors 32a; 32b, 34a; 34b attached to the openings 30° 32 formed here, the side surface near the baggage to be unloaded can be partially opened. It will be possible to do so.

In this way, in this first embodiment, even if
Even if the loading order is incorrect, it is possible to respond well and easily unload the cargo from this loading position without impairing workability.

On the other hand, currently, in the cargo transportation industry, a refrigerator is installed in the luggage compartment 14, and cargo that requires refrigeration is stored in the refrigerator and transported in a refrigerated state.

This kind of refrigerator is strategically installed at the innermost part of the luggage compartment 14, and when luggage is piled up in the luggage compartment on the front side of this refrigerator, it will be placed before the luggage stacked here. When unloading the items in the refrigerator, a problem similar to the above-mentioned case of loading the items in the wrong order will occur. For this reason, conventionally, the cargo compartment 1 on the front side of the refrigerator
In step 4, I try not to pile up luggage, or I try to unload the luggage from the front. In this way, in the former case, the transportation efficiency becomes very low, and in the latter case, as mentioned above, it is very time-consuming and the work efficiency is poor.

However, in this first embodiment, the luggage compartment 14
When taking out the luggage stored in the refrigerator installed in the innermost part of the refrigerator, pull the front sliding door 32a backward,
By partially opening the side of the luggage compartment 14, the refrigerator can be easily accessed. As a result, it becomes possible to stack luggage in the luggage compartment on the front side of the refrigerator, greatly improving transportation efficiency.

It goes without saying that the present invention is not limited to the configuration of the first embodiment described above, and can be modified in various ways without departing from the gist of the invention.
