The flange portion 22c is fixed to the floor member 14 by an appropriate fixing means such as a bolt.

The description will be continued with reference to FIGS. 2 and 3. The cargo compartment of the box-type cargo bed 2 is divided into a plurality of spaces by a partition wall 30 extending from the floor surface to the ceiling surface. In the illustrated embodiment, the cargo compartment of the box-type cargo bed 2 is divided into three spaces A, B, and C by a partition wall 30.
The partition wall 30 includes four left and right partition wall members 32 that are detachably installed in parallel to the side surface of the box-type cargo bed 2, and two front and rear partition walls that are installed in parallel to the front surface of the box-type cargo bed 2. A member 34 is included. Each of the left and right partition wall members 32 and the front and rear partition wall members 34 has a rectangular shape, and a seal member 36 is disposed on each side except the lower side. That is, the seal member 36 is also attached to the upper end portion of the left and right partition wall members 32. For example, urethane foam (foamed polyurethane) is used as the seal member 36, but various foamed synthetic resin materials having flexibility can be used. The seal member 36 is bonded to each side except for the lower sides of the left and right partition wall members 32 and the front and rear partition wall members 34 via appropriate bonding means such as an adhesive tape. On the wall surface of the left and right partition wall members 32, there are a lashing rail 38 used when the front and rear partition wall members 34 are fixed, and three strip-shaped grip portions used when the user installs and removes the left and right partition wall members 32. 40 is provided. The lashing rail 38 may be a well-known one, and a detailed description thereof is omitted in this specification.

Referring to FIG. 5, the left and right partition wall members 32 are initially left and right partition wall members 32 in a state where the left and right partition wall members 32 are somewhat inclined with respect to the vertical direction as indicated by broken lines in FIG. 5. Of the left and right partition wall members 32 inserted into the ceiling rail 20, and the left and right partition wall members 32 are gradually swung in the upright direction and lifted somewhat upward. The lower end of the left and right partition wall member 32 is inserted into the floor rail 22 by being pushed into the cargo compartment of the box-type cargo bed 2. Since the seal member 26 and the seal member 36 have elasticity, when the upper end portions of the left and right partition wall members 32 are fitted into the ceiling rail 20, the seal member 26 and the seal member 36 are deformed and can be easily installed. It can be performed.
In a state where the left and right partition wall members 32 are installed in the cargo compartment of the box-type loading platform 2, the left and right partition wall members 32 are arranged in the left-right direction by the ceiling rail 20 at the upper end and the floor rail 22 at the lower end. The movement is restricted, and the movement in the front-rear direction is restricted by the frictional force between the upper end portion and the ceiling rail 20 and the frictional force between the lower end portion and the floor rail 22. Thereby, in the box- type loading platform 2, the left and right partition wall members 32 can be installed in the cargo compartment without providing a relatively heavy member such as a lock on the left and right partition wall members 32. It becomes possible to reduce the load of the installation and removal work of the left and right partition wall members 32 by the operator.
When the left and right partition wall members 32 are installed in the cargo compartment of the box-type loading platform 2, as clearly understood by referring to FIG. 5, the ceiling between the upper ends of the left and right partition wall members 32 and the ceiling rails 20 is the ceiling. The seal member 26 of the rail 20 and the seal member 36 of the left and right partition wall members 32 are sealed. As described above, when the four left and right partition wall members 32 are respectively installed in the luggage compartment of the box-type loading platform 2, the four left and right partition wall members 32 are clearly understood by referring to FIG. 3. In this case, the space between the front and rear end faces is hermetically sealed via the seal member 36, and the whole is in a single-wall state.

  2 and FIG. 3, the two front and rear partition wall members 34 are sealed between the left and right end surfaces via a seal member 36, so that the front end It is closely attached to the seal member 36 provided on the front end face of the left and right partition wall member 32 located at, and is detachably installed in the cargo compartment of the box-type cargo bed 2. When the front and rear partition wall members 34 are installed in the cargo compartment of the box-type cargo bed 2, a seal member is provided between the upper end portion of the front and rear partition wall members 34 and the top panel 12 of the cargo compartment of the box-type cargo bed 2. It will be in a sealed state via 36. Since the sealing member 36 is flexible, the front and rear partition walls 34 can be installed in the cargo compartment of the box-type loading platform 2 even in a portion where the top panel 12 is not provided with an opening groove. The front / rear partition wall member 34 inserts a well-known lashing belt into an insertion portion provided on the wall surface, and attaches one end of the lashing belt to a lashing rail provided on the inner surface of the left side panel 8 and other lashing belts. By attaching the end to a lashing rail provided on the inner surface of the right side panel 10, it is fixed to the luggage compartment of the box-type carrier 2 (see also FIG. 8).

  By installing the left and right partition wall members 32 and the front and rear partition wall members 34 in the cargo compartment of the box-type carrier 2 as described above, the cargo compartment of the box-type carrier 2 has three spaces as shown in FIG. The front panel 4, the front part of the left side panel 8, the front part of the right side panel 10, and the space A defined by the front and rear partition wall members 34, the front and rear partition wall members 34, the rear part of the left side panel 8, and the left and right partitions A space B defined by the wall member 32 and the rear door 6 is divided into a front and rear partition wall member 34, a left and right partition wall member 32, a rear portion of the right side panel 10, and a space C defined by the rear door 6. Is done. As described above, the upper end portion of the left and right partition wall member 32 and the ceiling rail 20 are in a sealed state via the seal member 26 of the ceiling rail 20 and the seal member 36 of the left and right partition wall member 32, and adjacent four pieces. The movement of air between the space B and the space C divided by the left and right partition wall members 32 due to the sealed state between the front and rear end surfaces of the left and right partition wall members 32 via the seal member 36. Is prevented. Further, as described above, the space A and the space between the upper end portion of the front and rear partition wall members 34 and the top panel 12 of the cargo compartment of the box-type cargo bed 2 are sealed through the seal member 36. The movement of air between the space B or the space A and the space C is also prevented. Thereby, it is possible to prevent dust and dust from entering the space in the cargo compartment divided by the left and right partition wall members 32.

Since the left and right partition wall members 32 and the front and rear partition wall members 34 are detachably installed in the cargo compartment of the box-type loading platform 2, the volume of each space is arbitrarily adjusted according to the amount of cargo stored in each divided space. Is possible.
For example, when the amount of cargo stored in the space A is relatively large compared to the amount of cargo stored in the spaces B and C, as shown in FIG. By moving one of the partition wall members 34 rearward, the volume of the space A can be expanded. When it is desired to expand the volume of the space A further than in the case illustrated in FIG. 6A, the left and right partition wall members 32 installed at the front are removed and the front and rear partitions are removed as illustrated in FIG. 6B. By appropriately moving the wall 34 backward, the volume of the space A can be further expanded. In this case, a ceiling rail cover, which will be described later, is installed on the ceiling rail 20 where the left and right partition wall members 32 are not installed, and a floor rail 22 where the left and right partition wall members 32 are not installed are described later. It is preferable to install a floor rail cover.
When it is desired to divide the cargo compartment of the box-type loading platform 2 into two spaces instead of three, as shown in FIG. 6C, one of the front and rear partition wall members 34 is removed from the state shown in FIG. By removing, the cargo compartment of the box-type cargo bed 2 can be divided into two spaces. Furthermore, as shown in FIG. 6 (d), the ceiling rail 20 and the floor rail 22 are provided from the rear end to the front end of the box-type loading platform 2, and all the front and rear partition wall members 34 are removed and the left and right partition wall members 32 are provided. Furthermore, one can be added and the luggage compartment of the box-type luggage carrier 2 can be divided in the left-right direction.
Further, in the box- type loading platform 2, as long as the upper ends of the left and right partition wall members 32 are inserted into the ceiling rail 20 and the lower ends thereof are inserted into the floor rails 22, the left and right partition wall members 32 are moved into the cargo compartment. Since it can be installed in an arbitrary place, as shown in FIG. 6E, a small space S is formed at an arbitrary position in the cargo compartment using the left and right partition wall members 32 and the front and rear partition wall members 34. In addition, the degree of freedom for adjusting the volume of each space in the cargo compartment divided by the partition wall 30 is high. Accordingly, each space can be freely adjusted according to the amount of cargo to be stored, and the cargo storage efficiency of the entire cargo compartment of the box-type cargo bed 2 can be increased.

  Next, as shown in FIGS. 7A to 7C, a part or all of the left and right partition wall members 32 are removed, and the front and rear partition wall members 34 intersect the concave ceiling rails 20 (and the floor rails 22). Thus, the problem that occurs when the above-described box-type loading platform 2 is provided in the cargo compartment will be described. In this case, as clearly understood by referring to FIG. 8, the top panel 12 is provided with a concave ceiling rail 20 and at the upper end of the front and rear partition wall members 34. Since the upper surface of the seal member 36 is generally flat, an opening that communicates one space (space D) partitioned by the front and rear partition wall members 34 and the other space (space E) above the front and rear partition wall members 34. 46 is formed, through which air moves between the two spaces.

Therefore, in the box-bed of the present invention, independent of the partition wall member 32 ceiling rail 20 that it is not installed ceiling rail cover 42 is removably mounted, ceiling surface is the surface of the box-type bed of luggage compartment Become one. Longitudinal length of the ceiling rail cover 42 is in the range substantially the same as the length in the front-rear direction of the left and right partition wall member 32 is good preferable.
With reference to FIGS. 9 and 10, a ceiling rail cover 42 includes a cover surface 42a opposing the rail surface 20a of the ceiling rail 20, a pair of cover erected from both side edges of the cover surface 42a upward A side surface 42b and an engaging portion 42c are provided. The engaging portion 42 c is provided on the cover side surface 42 b and engages with the engaged portion 20 d provided on the ceiling rail 20 of the box-type loading platform 2. In the illustrated embodiment, two engaging portions 42c are provided at both ends in the longitudinal direction of each cover side surface 42b, and both engaging portions 42c are circular holes. Further, in the interior of at least one of the ceiling rail cover 42 of the upper surface and the ceiling rail 20 that is attached seal member having elasticity. In the illustrated embodiment, the seal member 48 is attached to the upper surface of the ceiling rail cover 42, that is, the upper surface of the cover surface 42a (the seal member 26 is also attached to the inside of the ceiling rail 20 as described above). . For example, urethane foam (foamed polyurethane) is used as the seal member 48, but various foamed synthetic resin materials having flexibility can be used. The seal member 48 is bonded to the upper surface of the cover surface 42a of the ceiling rail cover 42 through an appropriate bonding means such as an adhesive. A string-like gripping portion 50 is provided on the lower surface of the longitudinal end portion of the cover surface 42a.
If desired, the floor rail cover 44 is also installed on the floor rail 22 where the left and right partition wall members 32 are not installed. Referring to FIG. 9, the floor rail cover 44 is a flat plate member having a shape corresponding to the opening groove of the floor rail 22, and a string-like grip 52 is provided on the upper surface thereof. .

A method of installing the ceiling rail cover 42 on the ceiling rail 20 will be described with reference to FIG. 8 and FIG. The ceiling rail cover 42 is attached to the ceiling rail 20 in a portion where the left and right partition wall members 32 are not installed.
The ceiling rail cover 42 is inserted into the opening groove of the ceiling rail 20 such that the cover surface 42a faces the rail surface 20a of the ceiling rail 20 and the cover side surface 42b faces the rail side surface 20b of the ceiling rail 20. At that time, using the elasticity of the U-shaped cross section of the ceiling rail cover 42, the engaging portion 42 c of the ceiling rail cover 42 and the engaged portion 20 d of the ceiling rail 20 are engaged with each other to be attached to the ceiling rail 20. Is done.
When the ceiling rail cover 42 is attached to the ceiling rail 20, the upper surface of the ceiling rail cover 42, that is, the upper surface of the cover surface 42a, and the ceiling rail 20 are in a sealed state via the sealing member 26 and the sealing member 48, The opening 46 described above is closed by the ceiling rail cover 42. Thus, when the front and rear partition wall members 34 are provided in the cargo compartment of the box-type cargo bed 2 so as to intersect the concave ceiling rails 20, the one space (space D) divided by the front and rear partition wall members 34 is the other. The amount of air moving through the opening 46 to the space (space E) is reduced. In addition, when the ceiling rail cover 42 is mounted on the ceiling rail 20, the ceiling surface of the luggage compartment of the box-type cargo bed 2 is flush with the front and rear partition wall members 34 so as to intersect the concave ceiling rail 20. In the case where it is provided in the cargo compartment of the box-type loading platform 2, the opening 46 becomes sufficiently small, and the space between one space (space D) divided by the front and rear partition wall members 34 and the other space (space E) is set. The amount of moving air can be further reduced.
When removing the ceiling rail cover 42 from the ceiling rail 20, the holding portion 50 provided on the lower surface of the end portion of the cover surface 42 a of the ceiling rail cover 42 shown in FIG. 9 is held and pulled downward. As a result, the engagement between the engagement portion 42 c of the ceiling rail cover 42 and the engagement portion 20 d of the ceiling rail 20 is released, and the ceiling rail cover 42 can be removed from the ceiling rail 20.

Further, in the box-type cargo bed 2, one of a plurality of spaces divided by the partition wall 30 is surrounded by a heat insulating material, and an evaporator that cools the room is installed in the space surrounded by the heat insulating material. The room temperature of the space surrounded by can be made lower than room temperature. In this case, the left and right partition wall members 32 and the front and rear partition wall members 34 are so-called sandwich structure type heat insulating panels in which a heat insulating material such as expanded polystyrene is sandwiched from both sides by a thin resin plate such as polycarbonate. Further, the front panel 4, the rear door 6, the left side panel 8, the right side panel 10, and the top panel 12 are sandwich structure heat insulating panels in which a heat insulating material is sandwiched from both sides with a metal thin plate. It is preferable that an appropriate heat insulating material is provided.
Then, for example, evaporators (not shown) are arranged on the lower surfaces of the top panel 12 in the space A and the space B shown in FIG. 2, respectively, and the evaporators are respectively connected to appropriate refrigeration apparatuses, and the room temperature of the space A is set to −20 ° C. The room B is set to + 5 ° C. to be a refrigerated room, and the room C is kept at room temperature to be a dry room. In this case, as described above, the upper end portion of the left and right partition wall member 32 and the ceiling rail 20 are in a sealed state via the seal member 26 of the ceiling rail 20 and the seal member 36 of the left and right partition wall member 32. The front and rear end surfaces of the four adjacent left and right partition wall members 32 are in a sealed state via a seal member 36, and are divided into a space B (refrigeration chamber) and a space C (dry chamber) divided by the left and right partition wall members 32. The movement of cold air or warm air between the refrigeration apparatus and the refrigeration apparatus can be prevented from lowering the cooling efficiency. The frozen product is stored in the freezer (space A), the refrigerated product is stored in the refrigerator (space B), and the normal cargo that does not require temperature control is stored in the dry chamber (space C). Goods and normal cargo can be stored and delivered in the luggage compartment of the same box-type carrier 2 and the transportation efficiency can be improved.

  Although the box-type cargo bed of the present invention has been described in detail with reference to the accompanying drawings, the box-type cargo bed of the present invention is not limited to this, and various modifications can be considered. For example, in the box type carrier of the present invention, the ceiling rail and the floor rail extend in parallel with the side surface of the box type carrier, but the ceiling rail and the floor rail extend in parallel with the front surface of the box type carrier, It is also possible to insert the upper end portion of the front and rear partition walls into the ceiling rail and the lower end portion thereof into the floor rail.
